Description

本発明は、木材を圧縮することによって所定の形状に加工する木材の加工方法に関する。   The present invention relates to a wood processing method for processing wood into a predetermined shape by compressing the wood.

近年、木材を圧縮することによって所定の形状に加工する技術が注目されている。自然素材である木材はさまざまな木目を有するため、原木である無垢材から形取る箇所に応じて個体差が生じ、その個体差が製品ごとの個性となる。また、長期の使用によって生じる傷や色合いの変化自体も、独特の風合いとなって使用者に親しみを生じさせることがある。これらの理由により、合成樹脂や軽金属を用いた製品にはない、個性的で味わい深い製品を生み出すことのできる素材として、木材が注目されている。   In recent years, a technique for processing a predetermined shape by compressing wood has been attracting attention. Wood, which is a natural material, has a variety of grain, so individual differences occur depending on the location of the raw wood, which is the raw wood, and the individual differences become the individuality of each product. In addition, scratches and changes in color caused by long-term use may also have a unique texture and may be familiar to the user. For these reasons, wood is attracting attention as a material that can produce unique and tasty products that are not found in products using synthetic resins or light metals.

従来、木材の圧縮加工技術として、吸水軟化した１枚の木材を圧縮し、その木材を圧縮方向と略平行に切断して板状の一次固定品を得た後、この一次固定品を加熱吸水させながら所定の三次元形状に成形する技術が知られている（例えば、特許文献１を参照）。また、軟化処理した状態で圧縮した１枚の木材を所定の型枠で仮固定し、この木材の回復を型内で行って型成形する技術も知られている（例えば、特許文献２を参照）。   Conventionally, as a wood compression processing technique, a piece of wood that has been softened by water absorption is compressed, the wood is cut substantially parallel to the compression direction to obtain a plate-like primary fixed product, and then this primary fixed product is heated and absorbed by water. There is known a technique of forming a predetermined three-dimensional shape while performing the process (for example, see Patent Document 1). In addition, a technique is also known in which a piece of wood compressed in a softened state is temporarily fixed with a predetermined mold frame, and this wood is restored in a mold and molded (for example, see Patent Document 2). ).

特許第３０７８４５２号公報Japanese Patent No. 3078452 特開平１１−７７６１９号公報JP-A-11-77619

木材を圧縮加工する場合には、木材の個体差や種類、加工後の木材の強度やその用途などを含むさまざまな点を考慮して木材の肉厚や圧縮率を決める必要がある。例えば加工後の木材の強度を向上させるには肉厚をある程度厚くせざるを得ないが、従来のように１枚の木材を圧縮して成形する場合には、肉厚を厚くすることによって成形の困難度が増加してしまうという問題があった。   When compressing wood, it is necessary to determine the thickness and compression ratio of the wood in consideration of various points including individual differences and types of wood, strength of the processed wood, and its use. For example, in order to improve the strength of wood after processing, it is necessary to increase the thickness to some extent, but in the case where one piece of wood is compressed and molded as in the past, it is formed by increasing the thickness. There was a problem that the degree of difficulty increased.

また、木材には繊維方向が存在するため、１枚の木材を圧縮して成形を行うと、加工した木材がその繊維方向に応じた非一様な強度分布を有し、適切な強度に達していない方向が生じる場合があった。   In addition, since there is a fiber direction in wood, when one piece of wood is compressed and molded, the processed wood has a non-uniform strength distribution according to the fiber direction and reaches an appropriate strength. There was a case where a direction that did not occur.

これらの問題を解決するために、既製の合板を圧縮して加工を行うことが考えられるが、この場合には合板を構成する各木材の繊維方向によって伸縮の度合いが異なるため、圧縮によって割れ等が発生する上、各木材を接着する接着剤が表面に浮き出してしまうという問題もあり、実用に耐え得る製品を加工することはできなかった。   In order to solve these problems, it is conceivable to perform processing by compressing a ready-made plywood, but in this case, the degree of expansion and contraction differs depending on the fiber direction of each wood constituting the plywood, so cracking due to compression, etc. In addition, there is a problem in that the adhesive that bonds each piece of wood rises on the surface, and it has not been possible to process a product that can withstand practical use.

（実施の形態１）
図１は、本発明の実施の形態１に係る木材の加工方法によって形成される圧縮木製品を外装材とする電子機器の構成を示す斜視図である。同図に示す電子機器はデジタルカメラ１００であり、略椀状の木製のカバー部材１１および１２が組み合わさって成る略直方体形状の外装材１の内部に各種電子部材が収容されている。 (Embodiment 1)
FIG. 1 is a perspective view showing a configuration of an electronic device having a compressed wood product formed by the wood processing method according to Embodiment 1 of the present invention as an exterior material. The electronic apparatus shown in FIG. 1 is a digital camera 100 in which various electronic members are accommodated in a substantially rectangular parallelepiped exterior material 1 formed by combining substantially bowl-shaped wooden cover members 11 and 12.

図２は、カバー部材１１および１２の構成を示す斜視図である。カバー部材１１は、略長方形状の表面をなす主板部１１ａと、この主板部１１ａの長手方向に沿って主板部１１ａと略直交する方向に立ち上がって延出する二つの側板部１１ｂと、主板部１１ａの短手方向に沿ってその主板部１１ａと略直交する方向に立ち上がって延出する二つの側板部１１ｃとを有する。   FIG. 2 is a perspective view showing the configuration of the cover members 11 and 12. The cover member 11 includes a main plate portion 11a having a substantially rectangular surface, two side plate portions 11b extending and extending in a direction substantially orthogonal to the main plate portion 11a along the longitudinal direction of the main plate portion 11a, and the main plate portion. It has two side plate portions 11c that rise and extend in a direction substantially orthogonal to the main plate portion 11a along the short direction of 11a.

カバー部材１２もカバー部材１１と略同形状をなし、略長方形状の表面をなす主板部１２ａと、この主板部１２ａの長手方向に沿って主板部１２ａと略直交する方向に立ち上がって延出する二つの側板部１２ｂと、主板部１２ａの短手方向に沿ってその主板部１２ａと略直交する方向に立ち上がって延出する二つの側板部１２ｃとを有する。   The cover member 12 also has substantially the same shape as the cover member 11, and rises and extends in a direction substantially orthogonal to the main plate portion 12 a along the longitudinal direction of the main plate portion 12 a and the main plate portion 12 a having a substantially rectangular surface. Two side plate portions 12b and two side plate portions 12c rising and extending in a direction substantially orthogonal to the main plate portion 12a along the short direction of the main plate portion 12a are provided.

図３は図１のＡ−Ａ線断面図である。この図３および上述した図２に示すように、カバー部材１１および１２は、個別に圧縮した２枚の木材を重ねて接着することによって形成される。より具体的には、カバー部材１１は外部材１１１および内部材１１２の二層から成る一方、カバー部材１２は外部材１２１および内部材１２２の二層から成る。   3 is a cross-sectional view taken along line AA of FIG. As shown in FIG. 3 and FIG. 2 described above, the cover members 11 and 12 are formed by stacking and bonding two pieces of individually compressed wood. More specifically, the cover member 11 is composed of two layers of an outer member 111 and an inner member 112, while the cover member 12 is composed of two layers of an outer member 121 and an inner member 122.

外部材１１１はカバー部材１１の長手方向に略平行な繊維方向Ｌ111を有する一方、内部材１１２はカバー部材１１の短手方向に略平行な繊維方向Ｌ112を有する。また、外部材１２１はカバー部材１２の長手方向に略平行な繊維方向Ｌ121を有する一方、内部材１２２はカバー部材１２の短手方向に略平行な繊維方向Ｌ122を有する。したがって、各カバー部材を構成する外部材と内部材の繊維方向は略直交している。 The outer member 111 has a fiber direction L 111 substantially parallel to the longitudinal direction of the cover member 11, while the inner member 112 has a fiber direction L 112 substantially parallel to the short direction of the cover member 11. The outer member 121 has a fiber direction L 121 substantially parallel to the longitudinal direction of the cover member 12, while the inner member 122 has a fiber direction L 122 substantially parallel to the short direction of the cover member 12. Therefore, the fiber directions of the outer member and the inner member constituting each cover member are substantially orthogonal.

カバー部材１１の主板部１１ａには、撮像レンズを有する撮像部５およびフラッシュ６をそれぞれ表出する開口部１３および１４が形成されている。また、カバー部材１１の側板部１１ｂおよび１１ｃには、それぞれ切り欠き１５１および１６１が形成されている。   In the main plate portion 11a of the cover member 11, openings 13 and 14 are formed to expose the imaging unit 5 having the imaging lens and the flash 6, respectively. Further, notches 151 and 161 are formed in the side plate portions 11b and 11c of the cover member 11, respectively.

他方、カバー部材１２の主板部１２ａには、画像情報や文字情報を表示するために液晶ディスプレイ、プラズマディスプレイ、または有機ＥＬ（Electroluminescence）ディスプレイ等によって実現される表示部８を表出する開口部１７が形成されており、この開口部１７表面には、表示部８を保護するガラス等の保護部材が装着される。カバー部材１２の側板部１２ｂおよび１２ｃには、切り欠き１５２および１６２がそれぞれ形成されている。   On the other hand, the main plate portion 12a of the cover member 12 has an opening 17 for displaying the display portion 8 realized by a liquid crystal display, a plasma display, an organic EL (Electroluminescence) display or the like for displaying image information and character information. A protective member such as glass for protecting the display unit 8 is attached to the surface of the opening 17. Cutouts 152 and 162 are formed in the side plate portions 12b and 12c of the cover member 12, respectively.

これら二つのカバー部材１１および１２を用いてデジタルカメラ１００を組み立てると、切り欠き１５１と１５２が向かい合って開口部１５を形成し、切り欠き１６１と１６２が向かい合って開口部１６を形成する。このうち開口部１５はシャッターボタン７を表出する一方、開口部１６はパソコン等の外部機器への接続を行う接続デバイスを表出する。この接続デバイスは、例えばＵＳＢ（Universal Serial Bus）等の接続用端子、ｘＤピクチャーカードやスマートメディア等の外部記憶媒体を装着する装着用デバイス、および電源等の差込用ジャックなどである。これらの接続デバイスを未使用時に保護するため、開口部１６に蓋を装着してもよい。   When the digital camera 100 is assembled using these two cover members 11 and 12, the notches 151 and 152 face each other to form the opening 15, and the notches 161 and 162 face each other to form the opening 16. Of these, the opening 15 represents the shutter button 7, while the opening 16 represents a connection device for connecting to an external device such as a personal computer. This connection device is, for example, a connection terminal such as a USB (Universal Serial Bus), a mounting device for mounting an external storage medium such as an xD picture card or smart media, and a plug-in jack such as a power source. In order to protect these connection devices when not in use, a lid may be attached to the opening 16.

なお、カバー部材１１および１２には、上述した開口部や切り欠き以外にも、ファインダを取り付けたり操作入力ボタンを表出するための開口部や切り欠き等をさらに形成してもよい。   The cover members 11 and 12 may further be formed with openings and notches for attaching a finder and exposing operation input buttons, in addition to the openings and notches described above.

外装材１の内部には、図３に示すように、デジタルカメラ１００が有する電子的機能を実現する電子部材のうちの少なくとも一部、より具体的にはデジタルカメラ１００の撮像処理等に関する駆動制御を行う制御回路、ＣＣＤ（Charge Coupled Device）等の撮像素子、および音声の入出力を行うマイクロフォンやスピーカを含む電子部材を備えた制御部９が収納されている。このうち制御回路は、演算および制御機能を有するＣＰＵ（Central Processing Unit）、および所定のＯＳ（Operation System）を起動するプログラム等の各種情報を記憶するフラッシュメモリなどによって実現される。   As shown in FIG. 3, the exterior material 1 includes at least a part of electronic members that realize an electronic function of the digital camera 100, more specifically drive control related to imaging processing of the digital camera 100. And a control unit 9 including an electronic member including a control circuit for performing image pickup, an image pickup device such as a CCD (Charge Coupled Device), and a microphone and speaker for inputting and outputting sound. Among these, the control circuit is realized by a CPU (Central Processing Unit) having calculation and control functions, and a flash memory for storing various information such as a program for starting a predetermined OS (Operation System).

電子部材を格納して外装材１を組み立てる際には、カバー部材１１とカバー部材１２の対向する側板部端面に接着剤等を塗布して互いに接合する。この後、二つのカバー部材の接合部分の外周を弾性部材等から成る封止部材を用いて封止してもよい。また、接合部分となる二つのカバー部材の側板部端部のうちいずれか一方のカバー部材の側板部端部に溝部を穿設し、他方のカバー部材の側板部端部にはその溝部に嵌合可能な突起部を形成しておき、接合時に両者を嵌合するようにしてもよい。   When the exterior member 1 is assembled by storing the electronic member, an adhesive or the like is applied to the opposing side plate portion end surfaces of the cover member 11 and the cover member 12 and joined together. Then, you may seal the outer periphery of the junction part of two cover members using the sealing member which consists of an elastic member etc. Also, a groove portion is formed in the end portion of the side plate portion of one of the two cover members to be joined, and the end portion of the side plate portion of the other cover member is fitted in the groove portion. Protruding portions that can be combined may be formed, and both may be fitted together during bonding.

次に、以上の構成を有するカバー部材の加工方法を詳細に説明する。まず、カバー部材１１および１２の原材料となる木材を無垢材から形取る。図４は、カバー部材１１および１２の原材料となる木材を無圧縮状態の無垢材５０から形取る状況を模式的に示す説明図である。外部材１１１または１２１の原材料となる木材５１は平板状をなし、その木材５１の長手方向が無垢材５０の繊維方向Ｌに略平行となるように無垢材５０から形取られる。このように形取られた木材５１は、図５に示すように、肉厚Ｒを有し、表面の木目５０Ｇが略平行に走る柾目材である。   Next, a method for processing the cover member having the above configuration will be described in detail. First, the wood used as the raw material for the cover members 11 and 12 is formed from a solid material. FIG. 4 is an explanatory view schematically showing a situation in which the wood that is the raw material of the cover members 11 and 12 is formed from the uncompressed solid material 50. The wood 51 that is the raw material of the external material 111 or 121 has a flat plate shape, and is shaped from the solid material 50 so that the longitudinal direction of the wood 51 is substantially parallel to the fiber direction L of the solid material 50. As shown in FIG. 5, the wood 51 shaped in this way has a wall thickness R and is a grid material having a surface grain 50G that runs substantially in parallel.

これに対し、内部材１１２または１２２の原材料となる木材５２も平板状をなし、その木材５２の短手方向が無垢材５０の繊維方向Ｌに略平行となるように無垢材５０からの形取りを行う。図６は形取った木材５２の構成を示す斜視図である。この木材５２も肉厚がＲの柾目材であるが、長手方向の長さは木材５１の長手方向の長さよりも短い。   On the other hand, the timber 52 that is the raw material of the inner member 112 or 122 also has a flat plate shape, and is shaped from the solid material 50 so that the short direction of the timber 52 is substantially parallel to the fiber direction L of the solid material 50. I do. FIG. 6 is a perspective view showing the configuration of the shaped wood 52. The wood 52 is also a grid material with a wall thickness of R, but the length in the longitudinal direction is shorter than the length in the longitudinal direction of the wood 51.

なお、木材５１および５２を無垢材５０から形取る際には、予め後述する圧縮工程によって減少する分の容積を加えておく。また、この実施の形態１で使用する無垢材は、檜、檜葉、桐、杉、松、桜、欅、黒檀、チーク、マホガニー、ローズウッドなどである。これらの無垢材は、本発明の全ての実施の形態で使用することができる。   In addition, when shaping | molding the timbers 51 and 52 from the solid material 50, the volume for the reduction | decrease by the compression process mentioned later is added beforehand. The solid materials used in the first embodiment are camellia, camellia leaf, paulownia, cedar, pine, cherry blossom, camellia, ebony, teak, mahogany, rosewood and the like. These solid materials can be used in all embodiments of the present invention.

次に、木材５１を圧縮する（圧縮工程）。図７は木材５１の圧縮工程の概要を示す説明図であり、図８は図７のＢ−Ｂ線断面図である。これらの図７および図８に示すように、圧縮工程では、二つの金型６１および７１を用いて木材５１を圧縮する。二つの金型のうち、木材５１の上方から木材５１に対して圧縮力を加える金型６１は、下方に突出する凸部６２を有する。これに対し、圧縮時に木材５１の下方から木材５１に対して圧縮力を加える金型７１は、下方に窪んだ凹部７２を有する。   Next, the wood 51 is compressed (compression process). FIG. 7 is an explanatory view showing an outline of the compression process of the wood 51, and FIG. 8 is a sectional view taken along line BB of FIG. As shown in FIGS. 7 and 8, in the compression process, the wood 51 is compressed using two molds 61 and 71. Of the two molds, a mold 61 that applies a compressive force to the wood 51 from above the wood 51 has a convex portion 62 that projects downward. On the other hand, the mold 71 that applies a compressive force to the wood 51 from below the wood 51 during compression has a recess 72 that is recessed downward.

この圧縮工程を行うに際して、まず木材５１を高温高圧の水蒸気雰囲気中に所定時間放置する。これにより、木材５１は過剰に水分を吸収して軟化する。その後、同じ水蒸気雰囲気中で二つの金型６１および７１のうち少なくともいずれか一方の金型を他方の金型に近づけるようにして木材５１を挟持圧縮する。図９は、この圧縮状態を示す図であり、図８と同じ切断面を有する縦断面図である。この図９に示すように、木材５１を二つの金型６１および７１で挟持、圧縮することにより、木材５１は凸部６２と凹部７２の隙間の三次元形状に相当する略椀状に変形する。   When performing this compression step, the wood 51 is first left in a high-temperature and high-pressure steam atmosphere for a predetermined time. Thereby, the wood 51 absorbs moisture excessively and softens. Thereafter, the wood 51 is sandwiched and compressed so that at least one of the two molds 61 and 71 is brought close to the other mold in the same water vapor atmosphere. FIG. 9 is a view showing this compressed state, and is a longitudinal sectional view having the same cut surface as FIG. As shown in FIG. 9, when the wood 51 is sandwiched and compressed by two molds 61 and 71, the wood 51 is deformed into a substantially bowl shape corresponding to the three-dimensional shape of the gap between the convex portion 62 and the concave portion 72. .

この実施の形態１においては、圧縮によって木材５１の肉厚ｒ1（＜Ｒ）は場所によらずほぼ均一となる。したがって、圧縮工程における木材５１の圧縮率Ｃ1は（Ｒ−ｒ1）／Ｒで与えられる。この圧縮率Ｃ1の具体的な数値は、０.５〜０.７程度である。 In the first embodiment, the wall thickness r 1 (<R) of the wood 51 becomes substantially uniform regardless of the location by compression. Therefore, the compression rate C 1 of the wood 51 in the compression process is given by (R−r 1 ) / R. A specific numerical value of the compression ratio C 1 is about 0.5 to 0.7.

図９に示す状態で所定時間放置した後、金型６１と金型７１を離間させて圧縮を解除し、水蒸気雰囲気を解いて木材５１を乾燥させる。この際、木材５１の材質によっては、二つの金型を離間すると元の形状に戻ってしまう場合もある。この場合には、金型６１および７１で木材５１を挟持した状態で圧縮を解除して乾燥を行う。木材５１の乾燥時間は、木材５１の形状や種類に応じて変化する。   After leaving for a predetermined time in the state shown in FIG. 9, the mold 61 and the mold 71 are separated to release the compression, the water vapor atmosphere is released, and the wood 51 is dried. At this time, depending on the material of the wood 51, when the two molds are separated, the original shape may be restored. In this case, in a state where the wood 51 is held between the molds 61 and 71, the compression is released and drying is performed. The drying time of the wood 51 varies depending on the shape and type of the wood 51.

なお、圧縮工程によって木材５１および５２の外縁に不要部分が形成された場合には、この不要部分を切削によって除去し、適当な端面処理を施す。   In addition, when an unnecessary part is formed in the outer edge of the timbers 51 and 52 by a compression process, this unnecessary part is removed by cutting and an appropriate end surface process is performed.

ここまで木材５１の圧縮工程を説明したが、木材５２に対しても同様の圧縮工程を行う。この木材５２の圧縮工程では、木材５１を圧縮するときの金型６１および７１とは異なる金型を用いることにより、圧縮された木材５１よりも若干小さい外形形状を有するとともに、場所によらずほぼ均一な肉厚ｒ2（＜Ｒ）を有する略椀状に変形される。したがって、この圧縮工程における木材５２の圧縮率Ｃ2は（Ｒ−ｒ2）／Ｒで与えられる。 Although the compression process of the wood 51 has been described so far, the same compression process is performed on the wood 52. In the compression process of the wood 52, by using a mold different from the molds 61 and 71 when the wood 51 is compressed, the outer shape is slightly smaller than that of the compressed wood 51 and is almost independent of the place. It is deformed into a substantially bowl shape having a uniform thickness r 2 (<R). Therefore, the compression rate C 2 of the wood 52 in this compression step is given by (R−r 2 ) / R.

この実施の形態１では、圧縮工程後の木材５１の肉厚ｒ1と木材５２の肉厚ｒ2が等しくなるように金型が設計されている。このため、圧縮工程における木材５１の圧縮率Ｃ1と木材５２の圧縮率Ｃ2は等しい（Ｃ1＝Ｃ2）。以下では、圧縮工程によって成形された木材５１および５２を外部材１１１および内部材１１２とそれぞれ称する。 In the first embodiment, the mold is designed so that the thickness r 1 of the wood 51 after the compression process is equal to the thickness r 2 of the wood 52. Therefore, the compression ratio C 2 compression ratio C 1 and timber 52 of timber 51 in the compression step is equal (C 1 = C 2). Hereinafter, the woods 51 and 52 formed by the compression process are referred to as an outer member 111 and an inner member 112, respectively.

以上説明した圧縮工程の後、個別の圧縮工程で形成した外部材１１１と内部材１１２を図１０の説明図に示すように重ねて適量の接着剤を両部材の接着面に塗布し、接着する（接着工程）。図１１は、この接着工程によって形成されたカバー部材１１原型の構成を示す斜視図であり、図１２は、図１１のＣ−Ｃ線断面図である（接着剤は図示せず）。   After the compression process described above, the outer member 111 and the inner member 112 formed in the individual compression processes are overlapped as shown in the explanatory view of FIG. 10, and an appropriate amount of adhesive is applied to the bonding surfaces of both members and bonded. (Adhesion process). FIG. 11 is a perspective view showing the configuration of the original cover member 11 formed by this bonding step, and FIG. 12 is a cross-sectional view taken along the line CC of FIG. 11 (adhesive is not shown).

この接着工程において、外部材１１１の内側面と内部材１１２の外側面とは同形状であるため、両部材の接着を行うに際して位置決めは不要であるが、接着圧力が適正な値となるように制御するには、何らかの治具を用いて接着を行った方がより好ましい。そのような治具として、外部材１１１の圧縮工程に用いる金型７１と内部材１１２の圧縮工程に用いる金型（図７の金型６１に相当する金型）とを組み合わせて用いることができる。この場合には、外部材１１１と内部材１１２を重ねたものを前述した二つの金型によって挟持した状態で適切な圧縮力を印加すればよい。   In this bonding step, the inner surface of the outer member 111 and the outer surface of the inner member 112 have the same shape, so positioning is not necessary when bonding both members, but the bonding pressure is set to an appropriate value. In order to control, it is more preferable to perform bonding using some kind of jig. As such a jig, a mold 71 used in the compression process of the outer member 111 and a mold used in the compression process of the inner member 112 (a mold corresponding to the mold 61 in FIG. 7) can be used in combination. . In this case, an appropriate compression force may be applied in a state in which the outer member 111 and the inner member 112 are overlapped by the two molds described above.

なお、カバー部材１１が有する開口部や切り欠きは、以上の工程が終了した後で切削または穿孔等によって形成する。図１１は、この接着工程によって形成されたカバー部材１１原型の構成を示す斜視図であり、図１２は、図１１のＣ−Ｃ線断面図である（接着剤は図示せず）。   In addition, the opening part and notch which the cover member 11 has are formed by cutting or drilling etc. after the above process is complete | finished. FIG. 11 is a perspective view showing the configuration of the original cover member 11 formed by this bonding step, and FIG. 12 is a cross-sectional view taken along the line CC of FIG. 11 (adhesive is not shown).

図１３は、圧縮工程と接着工程を経てカバー部材１１となる外部材１１１および内部材１１２内部の強度分布を状態ごとに模式的に示す縦断面図である。圧縮工程を経た後の外部材１１１および内部材１１２は、金型からの圧縮力を受ける表面付近の領域Ｓで繊維密度が増加し、その領域Ｓの強度が中間領域Ｍの強度よりも相対的に強くなる。   FIG. 13 is a longitudinal cross-sectional view schematically showing the strength distribution inside the outer member 111 and the inner member 112 that become the cover member 11 through the compression process and the bonding process for each state. After the compression process, the outer member 111 and the inner member 112 have an increased fiber density in the region S near the surface that receives the compression force from the mold, and the strength of the region S is relatively higher than the strength of the intermediate region M. Become stronger.

このような外部材１１１と内部材１１２を２枚重ねて接着してカバー部材１１を形成すると、そのカバー部材１１の表面付近の領域Ｓと同程度の強度を有する領域Ｓ'が中央部付近にも生じる。この中央部付近の領域Ｓ'は、元は外部材１１１と内部材１１２の表面付近の領域Ｓが接着によって重なってできた領域のため、その厚さは領域Ｓの２倍程度である。このようにしてカバー部材１１は、強度が相対的に強い層と弱い層とが交互にかつ多様に重なりあうようになり、靭性を備え、強くてしなやかな材質となる。   When the cover member 11 is formed by overlapping and bonding two such outer members 111 and 112, the region S ′ having the same strength as the region S near the surface of the cover member 11 is located near the center. Also occurs. Since the region S ′ near the center is originally a region where the region S near the surface of the outer member 111 and the inner member 112 is overlapped by adhesion, the thickness thereof is about twice that of the region S. In this way, the cover member 11 has a relatively strong layer and a weak layer that are alternately and variously overlapped with each other, and has a toughness and a strong and flexible material.

以上説明した本発明の実施の形態１によれば、２枚の木材を個別に圧縮した後、その２枚の木材を重ねて接着することにより、圧縮時における木材の肉厚を薄くすることができ、成形が容易になる。   According to the first embodiment of the present invention described above, after compressing two pieces of wood individually, the two pieces of wood are stacked and bonded, thereby reducing the thickness of the wood during compression. Can be formed easily.

また、この実施の形態１によれば、圧縮工程を経た結果、木材に強度が強い層と弱い層とが交互に現れるため、靭性も備え、強くてしなやかな材質の圧縮木製品を提供することができる。   Further, according to the first embodiment, as a result of the compression process, a strong layer and a weak layer appear alternately in the wood, so that a compressed wooden product having a toughness and a strong and flexible material can be provided. it can.

さらに、この実施の形態１によれば、カバー部材をなす外部材と内部材の繊維方向を略直交させることにより、表面方向に沿って強度が弱い部分を互いに補い合うことができるので、木材表面に沿った方向における強度の非一様性を解消することが可能となり、適切な強度を一様に付与することができる。   Furthermore, according to the first embodiment, by making the fiber directions of the outer member and the inner member forming the cover member substantially orthogonal to each other, it is possible to compensate for weak parts along the surface direction. It becomes possible to eliminate the non-uniformity of the strength in the direction along the direction, and an appropriate strength can be uniformly imparted.

なお、上述した実施の形態１とは逆に、外部材１１１の繊維方向を短手方向に略平行とし、内部材１１２の繊維方向を長手方向に略平行とすることにより、外部材１１１と内部材１１２の繊維方向を略直交させてもよい。   Contrary to Embodiment 1 described above, the outer member 111 and the inner member 112 are made substantially parallel to the short direction and the inner member 112 is made substantially parallel to the longitudinal direction. The fiber direction of the material 112 may be substantially orthogonal.

また、２枚の木材の繊維方向は上記の如く略直交していなくてもよく、少なくともそれらの木材の繊維方向が交差するように２枚の木材を形取れば、上記実施の形態１と同様の効果を得ることができる。この意味では、無垢材５０から形取る木材は柾目材でなくてもよい。   Further, the fiber directions of the two pieces of wood may not be substantially orthogonal as described above, and if the two pieces of wood are shaped so that at least the fiber directions of the pieces of wood intersect, they are the same as in the first embodiment. The effect of can be obtained. In this sense, the wood formed from the solid material 50 does not have to be a mesh material.

さらに、カバー部材１１とカバー部材１２とで、外部材と内部材が指向する繊維方向と外形形状との関係を逆にしてもよい。すなわち、カバー部材１１は上記実施の形態１と同様に形成する一方で、カバー部材１２の方は、外部材１２１の繊維方向が短手方向に略平行となり、内部材１２２の繊維方向が長手方向に略平行となるように形成してもよい。   Further, the cover member 11 and the cover member 12 may reverse the relationship between the fiber direction in which the outer member and the inner member are directed and the outer shape. That is, while the cover member 11 is formed in the same manner as in the first embodiment, in the cover member 12, the fiber direction of the outer member 121 is substantially parallel to the short direction, and the fiber direction of the inner member 122 is the longitudinal direction. You may form so that it may become substantially parallel to.

ところで、以上の説明では２枚の木材を重ねて圧縮木製品を形成する場合を扱ったが、３枚以上の木材を用いて加工することもできる。例えば柾目材を３枚用いる場合には、各々の木材の繊維方向が６０度の角度をなして交差するようにすれば、互いの強度の弱い部分を補い合うことができ、強度の向上を実現することができる。より一般にｎ枚（ｎは２以上の整数）の柾目材を用いる場合には、各々の繊維方向が（１８０／ｎ）度の角度をなして交差するようにすればよい。   By the way, in the above description, the case where two pieces of wood are stacked to form a compressed wood product has been dealt with, but it is also possible to process using three or more pieces of wood. For example, in the case of using three pieces of mesh material, if the fiber directions of the respective woods intersect at an angle of 60 degrees, the weak portions of each other can be compensated for, and an improvement in strength can be realized. be able to. More generally, when n sheets (n is an integer of 2 or more) are used, the fiber directions may intersect at an angle of (180 / n) degrees.

ここで、カバー部材１１および１２の数値例を挙げておく。まず、肉厚がＲ＝２ｍｍ程度の平板状の２枚の木材５１および５２を無垢材５０から形取る。圧縮工程では、これらの木材を０.８〜０.９ｍｍ程度の肉厚となるまでそれぞれ圧縮する。したがって、完成したカバー部材１１および１２の肉厚は、１.６〜１.８ｍｍ程度となる。   Here, numerical examples of the cover members 11 and 12 will be given. First, two flat wooden pieces 51 and 52 having a wall thickness of R = 2 mm are formed from the solid material 50. In the compression step, these timbers are respectively compressed until the thickness becomes about 0.8 to 0.9 mm. Therefore, the thickness of the completed cover members 11 and 12 is about 1.6 to 1.8 mm.

（実施の形態２）
図１４は、本発明の実施の形態２に係る木材の加工方法によって形成される圧縮木製品を外装材とする電子機器の構成を示す斜視図である。同図に示す電子機器はデジタルカメラ２００であり、略椀状の木製のカバー部材２１および２２が組み合わさって成る略直方体形状の外装材２の内部に各種電子部材が収容されている。 (Embodiment 2)
FIG. 14 is a perspective view showing a configuration of an electronic device having a compressed wood product formed by the wood processing method according to Embodiment 2 of the present invention as an exterior material. The electronic apparatus shown in FIG. 1 is a digital camera 200 in which various electronic members are accommodated in a substantially rectangular parallelepiped exterior member 2 formed by combining substantially bowl-shaped wooden cover members 21 and 22.

図１５は、カバー部材２１および２２の構成を示す斜視図である。カバー部材２１は、略長方形状の表面をなす主板部２１ａと、この主板部２１ａの長手方向に沿って主板部２１ａと略直交する方向に立ち上がって延出する二つの側板部２１ｂと、主板部２１ａの短手方向に沿ってその主板部２１ａと略直交する方向に立ち上がって延出する二つの側板部２１ｃとを有する。カバー部材１２もカバー部材２１と略同形状をなし、主板部２２ａと、この主板部２２ａの周縁からそれぞれ立ち上がって延出する側板部２２ｂおよび２２ｃを有する。   FIG. 15 is a perspective view showing the configuration of the cover members 21 and 22. The cover member 21 includes a main plate portion 21a having a substantially rectangular surface, two side plate portions 21b extending and extending in a direction substantially orthogonal to the main plate portion 21a along the longitudinal direction of the main plate portion 21a, and a main plate portion It has two side plate portions 21c that rise and extend in a direction substantially orthogonal to the main plate portion 21a along the short direction of 21a. The cover member 12 also has substantially the same shape as the cover member 21, and has a main plate portion 22a and side plate portions 22b and 22c that stand up and extend from the periphery of the main plate portion 22a.

カバー部材２１は、個別に圧縮した２枚の木材を重ねて接着することによって形成され、外部材２１１および内部材２１２の二層から成る。カバー部材２２もカバー部材２１と同様に形成され、外部材２２１および内部材２２２の二層から成る。この実施の形態２においては、各カバー部材を構成する外部材と内部材が異なる木目５０Ｇを有する。具体的には、外部材２１１および２２１が板目材である一方、内部材２１２および２２２は柾目材である。   The cover member 21 is formed by stacking and adhering two individually compressed pieces of wood, and consists of two layers of an outer member 211 and an inner member 212. The cover member 22 is also formed in the same manner as the cover member 21 and includes two layers, an outer member 221 and an inner member 222. In the second embodiment, the outer member and the inner member constituting each cover member have different grain 50G. Specifically, the outer members 211 and 221 are plate members, while the inner members 212 and 222 are plate members.

図１５に示す場合、板目材である外部材２１１および２２１の繊維方向は一様な方向を指向していない。これに対して柾目材である内部材２１２および２２２は、各々の繊維方向Ｌ212およびＬ222がカバー部材２１および２２の長手方向にそれぞれ略平行である。このように、非一様な繊維方向を有することが多い板目材を外部材とする一方で、一様な繊維方向を有する柾目材を内部材としてその両者を重ねてカバー部材２１および２２を形成することにより、互いの木材の繊維方向が交差するようになる。この結果、各カバー部材の強度の異方性が小さくなる。 In the case shown in FIG. 15, the fiber directions of the outer members 211 and 221 that are plate materials are not oriented in a uniform direction. On the other hand, in the inner members 212 and 222 which are mesh members, the fiber directions L 212 and L 222 are substantially parallel to the longitudinal direction of the cover members 21 and 22, respectively. In this way, while the plate member that often has non-uniform fiber directions is used as the outer member, the cover member 21 and 22 are overlapped by using the cross member having the uniform fiber direction as the inner member. By forming, the fiber direction of each wood crosses. As a result, the strength anisotropy of each cover member is reduced.

カバー部材２１の主板部２１ａは、撮像部５を表出する開口部２３とフラッシュ６を取り付ける開口部２４とを有する。また、カバー部材２１の側板部２１ｂおよび２１ｃには、それぞれ切り欠き２５１および２６１が形成されている。   The main plate portion 21 a of the cover member 21 has an opening 23 that exposes the imaging unit 5 and an opening 24 to which the flash 6 is attached. Further, notches 251 and 261 are formed in the side plate portions 21b and 21c of the cover member 21, respectively.

他方、カバー部材２２の主板部２２ａには、液晶ディスプレイ、プラズマディスプレイ、または有機ＥＬディスプレイ等によって実現される表示部８を表出する開口部２７が設けられ、この開口部２７表面には、表示部８を保護するガラス等の保護部材が装着される。カバー部材２２の側板部２２ｂおよび２２ｃには、それぞれ切り欠き２５２および２６２が形成されている。   On the other hand, the main plate 22a of the cover member 22 is provided with an opening 27 that exposes the display unit 8 realized by a liquid crystal display, a plasma display, an organic EL display, or the like. A protective member such as glass for protecting the portion 8 is attached. Cutouts 252 and 262 are formed in the side plate portions 22b and 22c of the cover member 22, respectively.

これら二つのカバー部材２１および２２を用いてデジタルカメラ２００を組み立てると、切り欠き２５１と２５２が向かい合って開口部２５を形成し、切り欠き２６１と２６２が向かい合って開口部２６を形成する。このうち開口部２５はシャッターボタン７を表出する一方、開口部２６はパソコン等の外部機器への接続を行う接続デバイスを表出する。この開口部２６には、未使用時に接続デバイスを保護するための蓋を装着してもよい。   When the digital camera 200 is assembled using these two cover members 21 and 22, the notches 251 and 252 face each other to form the opening 25, and the notches 261 and 262 face each other to form the opening 26. Of these, the opening 25 represents the shutter button 7, while the opening 26 represents a connection device for connecting to an external device such as a personal computer. A lid for protecting the connection device when not in use may be attached to the opening 26.

デジタルカメラ２００の内部は上述したデジタルカメラ１００の内部と同様の構成を有する（図３を参照）。すなわち、外装材２の内部には、デジタルカメラ２００における撮像処理などの機能を実現する電子部材の少なくとも一部をなす制御部９が収容されている。なお、外装材２の構成や組立方法等は、上記実施の形態１における外装材１の構成や組立方法等とそれぞれ同じである。   The inside of the digital camera 200 has the same configuration as the inside of the digital camera 100 described above (see FIG. 3). That is, inside the exterior material 2 is accommodated a control unit 9 that constitutes at least a part of an electronic member that realizes a function such as an imaging process in the digital camera 200. The configuration and assembly method of the exterior material 2 are the same as the configuration and assembly method of the exterior material 1 in the first embodiment.

次に、以上の構成を有するカバー部材の加工方法を詳細に説明する。まず、カバー部材２１および２２の原材料となる木材を、予め圧縮によって減少する容積を加えた形態で無垢材から形取る。図１６は、カバー部材２１および２２の原材料となる木材を無圧縮状態の無垢材５０から形取る状況を模式的に示す説明図である。外部材２１１または２２１の原材料となる木材５３は平板状をなし、その木材５３の長手方向が無垢材５０の繊維方向Ｌに略平行となるように形取られる。このように形取られた木材５３は板目材である（図１７を参照）。   Next, a method for processing the cover member having the above configuration will be described in detail. First, the wood used as the raw material of the cover members 21 and 22 is formed from a solid material in a form in which a volume that is reduced by compression is added in advance. FIG. 16 is an explanatory view schematically showing a situation in which the wood used as the raw material for the cover members 21 and 22 is formed from the uncompressed solid material 50. The wood 53 that is the raw material of the external material 211 or 221 has a flat plate shape and is shaped so that the longitudinal direction of the wood 53 is substantially parallel to the fiber direction L of the solid material 50. The wood 53 thus shaped is a plate material (see FIG. 17).

これに対して内部材２１２または２２２の原材料となる木材５４は、その長手方向が無垢材５０の繊維方向Ｌに略平行となるように形取られた柾目材である。この木材５４は、図５に示す木材５１と同様の構成を有する。木材５３および５４の肉厚はともにＲで等しく、木材５３の長手方向の長さは木材５４の長手方向の長さよりも長い。   On the other hand, the wood 54 which is a raw material of the inner member 212 or 222 is a mesh material shaped so that its longitudinal direction is substantially parallel to the fiber direction L of the solid material 50. The wood 54 has the same configuration as the wood 51 shown in FIG. The thicknesses of the timbers 53 and 54 are both equal to R, and the longitudinal length of the timber 53 is longer than the longitudinal length of the timber 54.

次に、形取った木材５３および５４を圧縮する（圧縮工程）。この圧縮工程では、圧縮を行う前に、木材５３および５４を高温高圧の水蒸気雰囲気中に所定時間放置する。その後、各木材に対して所定の二つの金型を用いることにより、水分を過剰に吸収して軟化した木材５３および５４をそれぞれ挟持、圧縮する。   Next, the shaped woods 53 and 54 are compressed (compression process). In this compression step, the woods 53 and 54 are left in a high-temperature and high-pressure steam atmosphere for a predetermined time before compression. After that, by using two predetermined molds for each wood, the woods 53 and 54 softened by excessively absorbing moisture are sandwiched and compressed, respectively.

この圧縮工程によって木材５３の肉厚ｒ3（＜Ｒ）および木材５４の肉厚ｒ4（＜Ｒ）は、場所によらずほぼ均一となる。木材５３の圧縮率Ｃ3＝（Ｒ−ｒ3）／Ｒおよび木材５４の圧縮率Ｃ4＝（Ｒ−ｒ4）／Ｒは、ともに０.５〜０.７程度である。なお、圧縮工程によって木材５３および５４の外縁に不要部分が形成された場合には、この不要部分を切削によって除去し、適当な端面処理を施す。 The thickness r 3 of the timber 53 by the compression process (<R) and the thickness r 4 of the timber 54 (<R) is almost uniform regardless of the location. The compression rate C 3 = (R−r 3 ) / R of the wood 53 and the compression rate C 4 = (R−r 4 ) / R of the wood 54 are both about 0.5 to 0.7. In addition, when an unnecessary part is formed in the outer edge of the timbers 53 and 54 by a compression process, this unnecessary part is removed by cutting and an appropriate end surface process is performed.

図１８は、上記圧縮工程で形成した外部材２１１と内部材２１２を乾燥させた後、その両部材を重ねて接着する接着工程の概要を示す説明図である。以下では、カバー部材２１の接着工程を説明するが、カバー部材２２の接着工程も同じである。   FIG. 18 is an explanatory diagram showing an outline of the bonding process in which the outer member 211 and the inner member 212 formed in the compression process are dried and then both the members are stacked and bonded. Below, although the adhesion process of the cover member 21 is demonstrated, the adhesion process of the cover member 22 is also the same.

この接着工程では、外部材２１１の内側面と内部材２１２の外側面の少なくとも一方に適量の接着剤を塗布することにより、両部材を接着し、カバー部材２１の原型を形成する。この接着工程においても、上記実施の形態１と同様、外部材２１１と内部材２１２を適確に接着するために適当な治具を用いてもよい。   In this bonding step, an appropriate amount of adhesive is applied to at least one of the inner surface of the outer member 211 and the outer surface of the inner member 212, thereby bonding both members to form a prototype of the cover member 21. Also in this bonding step, as in the first embodiment, an appropriate jig may be used to bond the outer member 211 and the inner member 212 appropriately.

このようにして形成したカバー部材２１の原型に対し、開口部や切り欠きを切削または穿孔によって形成し、デジタルカメラ２００の外装材２の一部をなすカバー部材２１が完成する。完成したカバー部材２１の肉厚は、圧縮前の二つの木材の肉厚の合計２Ｒの３０〜５０％程度となる。   The cover member 21 that forms part of the exterior material 2 of the digital camera 200 is completed by forming openings and notches in the original pattern of the cover member 21 thus formed by cutting or drilling. The thickness of the completed cover member 21 is about 30 to 50% of the total thickness 2R of the two woods before compression.

以上説明した本発明の実施の形態２によれば、上記実施の形態１と同様の効果を得ることができる。すなわち、この実施の形態２によれば、２枚の木材を個別に圧縮した後、この圧縮した２枚の木材を重ねて接着することにより、圧縮工程時における木材の肉厚を薄くすることができ、成形が容易になる。   According to the second embodiment of the present invention described above, the same effect as in the first embodiment can be obtained. That is, according to the second embodiment, after compressing two pieces of wood individually, the two pieces of compressed wood are stacked and bonded together, thereby reducing the thickness of the wood during the compression process. Can be formed easily.

また、この実施の形態２においても、圧縮によって強度が強い層と弱い層とが交互に現れるため（図１３を参照）、靭性も備えた強くてしなやかな圧縮木製品を提供することができる。   Also in the second embodiment, a strong layer and a weak layer appear alternately by compression (see FIG. 13), so that a strong and supple compressed wood product having toughness can be provided.

さらに、この実施の形態２によれば、カバー部材をなす外部材と内部材の木目を異なるものとすることにより、互いの繊維方向が交差し、表面方向に沿って強度が弱い部分を互いに補い合うことができる。この結果、木材表面に沿った方向における強度の非一様性を解消することが可能となり、適切な強度を一様に付与することができる。   Further, according to the second embodiment, the grain of the outer member and the inner member forming the cover member are different from each other, so that the fiber directions of each other intersect and the portions having low strength along the surface direction complement each other. be able to. As a result, it is possible to eliminate non-uniformity of strength in the direction along the wood surface, and appropriate strength can be imparted uniformly.

ところで、この実施の形態２では外部材として板目材を、内部材として柾目材を用いたが、これは次の意味で好ましい。すなわち、板目材は多様な木目を有しているため、そのような板目材を外部材として適用すれば意匠的な意味での個体差がより顕著になる。これに対して柾目材は異方性が小さく一様な繊維方向を有しているため、その繊維方向に垂直な方向の強度が強く、繊維方向に沿った曲げ加工を行うのが容易である。このように板目材と柾目材を組み合わせることにより、互いの長所を活かした圧縮木製品を提供することが可能となる。   By the way, in the second embodiment, a plate material is used as the outer member and a grid material is used as the inner member, which is preferable in the following sense. That is, since the grain material has a variety of grain, if such a grain material is applied as an outer member, the individual difference in the design sense becomes more remarkable. On the other hand, the mesh material has a small anisotropy and a uniform fiber direction, so the strength in the direction perpendicular to the fiber direction is strong, and it is easy to perform bending along the fiber direction. . Thus, it becomes possible to provide a compressed wood product that takes advantage of each other's advantages by combining the plate material and the mesh material.

なお、外部材として木口材を用いることも可能であるし、内部材として柾目材以外のもの、例えば追柾材を用いることも可能である。   In addition, it is also possible to use a timber material as an outer member, and it is also possible to use things other than a mesh material, for example, a memory material, as an inner member.

この実施の形態２においても、３枚以上の木材から圧縮木製品を加工することができる。上述したように、板目材や木口材は意匠的に見て個性的なので、例えば板目材または木口材を表面をなす部材として用いる一方、内側の部材として２枚の柾目材を互いの繊維方向が略直交するように重ねて接着すれば、強度と美観を兼ね備えた圧縮木製品を得ることができる。この場合には、板目材または木口材を他の２枚の柾目材よりも肉厚を薄く形取りを行ってもよい。   In the second embodiment, a compressed wooden product can be processed from three or more pieces of wood. As described above, since the grain material and the lip material are unique in terms of design, for example, the grain material or the lip material is used as a member that forms the surface, while two glazing materials are used as the inner members. If they are stacked and bonded so that the directions are substantially orthogonal, a compressed wood product having both strength and aesthetics can be obtained. In this case, the plate material or the mouthpiece material may be shaped to be thinner than the other two pieces of the mesh material.

（実施の形態３）
図１９は、本発明の実施の形態３に係る木材の加工方法によって形成される圧縮木製品を外装材とする電子機器の構成を示す斜視図である。同図に示す電子機器はデジタルカメラ３００であり、略椀状の木製のカバー部材３１および３２が組み合わさって成る略直方体形状の外装材３の内部に各種電子部材が収容されている。 (Embodiment 3)
FIG. 19 is a perspective view showing a configuration of an electronic device having a compressed wood product formed by the wood processing method according to Embodiment 3 of the present invention as an exterior material. The electronic apparatus shown in FIG. 1 is a digital camera 300, in which various electronic members are accommodated inside a substantially rectangular parallelepiped exterior member 3 formed by combining substantially bowl-shaped wooden cover members 31 and 32.

図２０は、カバー部材３１および３２の構成を示す斜視図である。カバー部材３１は、略長方形状の表面をなす主板部３１ａと、この主板部３１ａの長手方向に沿って主板部３１ａと略直交する方向に立ち上がって延出する二つの側板部３１ｂと、主板部３１ａの短手方向に沿ってその主板部３１ａと略直交する方向に立ち上がって延出する二つの側板部３１ｃとを有する。カバー部材３２もカバー部材３１と略同形状をなし、主板部３２ａと、この主板部３２ａの周縁からそれぞれ立ち上がって延出する側板部３２ｂおよび３２ｃを有する。   FIG. 20 is a perspective view showing the configuration of the cover members 31 and 32. The cover member 31 includes a main plate portion 31a having a substantially rectangular surface, two side plate portions 31b extending and extending in a direction substantially orthogonal to the main plate portion 31a along the longitudinal direction of the main plate portion 31a, and the main plate portion. It has two side plate portions 31c that rise and extend in a direction substantially orthogonal to the main plate portion 31a along the short direction of 31a. The cover member 32 also has substantially the same shape as the cover member 31, and has a main plate portion 32a and side plate portions 32b and 32c that stand up and extend from the periphery of the main plate portion 32a.

カバー部材３１は、個別に圧縮した２枚の木材を重ねて接着することによって形成され、外部材３１１および内部材３１２の二層から成る。カバー部材３２もカバー部材３１と同様に形成され、外部材３２１および内部材３２２の二層から成る。   The cover member 31 is formed by stacking and bonding two pieces of individually compressed wood, and consists of two layers of an outer member 311 and an inner member 312. The cover member 32 is also formed in the same manner as the cover member 31 and includes two layers of an outer member 321 and an inner member 322.

外部材３１１および３２１、ならびに内部材３１２および３２２は全て柾目材である。このうち、外部材３１１と内部材３１２の繊維方向はカバー部材３１の長手方向に略平行であり、重なり合う外部材３１１と内部材３１２の木目５０Ｇはほぼ揃っている。また、外部材３２１と内部材３２２の繊維方向はカバー部材３２の長手方向に略平行であり、重なり合う外部材３２１と内部材３２２の木目５０Ｇもほぼ揃っている。   The outer members 311 and 321 and the inner members 312 and 322 are all grid members. Among these, the fiber direction of the outer member 311 and the inner member 312 is substantially parallel to the longitudinal direction of the cover member 31, and the grain 50G of the overlapping outer member 311 and inner member 312 is substantially aligned. Further, the fiber directions of the outer member 321 and the inner member 322 are substantially parallel to the longitudinal direction of the cover member 32, and the overlapping grain 50G of the outer member 321 and the inner member 322 is substantially aligned.

カバー部材３１の主板部３１ａは、撮像部５を表出する開口部３３とフラッシュ６を取り付ける開口部３４とを有する。また、カバー部材３１の側板部３１ｂおよび３１ｃには、それぞれ切り欠き３５１および３６１が形成されている。   The main plate portion 31 a of the cover member 31 has an opening 33 that exposes the imaging unit 5 and an opening 34 to which the flash 6 is attached. Further, notches 351 and 361 are formed in the side plate portions 31b and 31c of the cover member 31, respectively.

他方、カバー部材３２の主板部３２ａには、液晶ディスプレイ、プラズマディスプレイ、または有機ＥＬディスプレイ等によって実現される表示部８を表出する開口部３７が設けられ、この開口部３７表面には、表示部８を保護するガラス等の保護部材が装着される。カバー部材３２の側板部３２ｂおよび３２ｃには、それぞれ切り欠き３５２および３６２が形成されている。   On the other hand, the main plate portion 32a of the cover member 32 is provided with an opening portion 37 that exposes the display portion 8 realized by a liquid crystal display, a plasma display, an organic EL display, or the like. A protective member such as glass for protecting the portion 8 is attached. Cutouts 352 and 362 are formed in the side plate portions 32b and 32c of the cover member 32, respectively.

これら二つのカバー部材３１および３２を用いてデジタルカメラ３００を組み立てると、切り欠き３５１と３５２が向かい合って開口部３５を形成し、切り欠き３６１と３６２が向かい合って開口部３６を形成する。このうち開口部３５はシャッターボタン７を表出する一方、開口部３６はパソコン等の外部機器への接続を行う接続デバイスを表出する。この開口部３６には、未使用時に接続デバイスを保護するための蓋を装着してもよい。   When the digital camera 300 is assembled using these two cover members 31 and 32, the notches 351 and 352 face each other to form the opening 35, and the notches 361 and 362 face each other to form the opening 36. Among these, the opening 35 represents the shutter button 7, while the opening 36 represents a connection device for connecting to an external device such as a personal computer. The opening 36 may be provided with a lid for protecting the connection device when not in use.

デジタルカメラ３００の内部は上述したデジタルカメラ１００の内部と同様の構成を有する（図３を参照）。すなわち、外装材３の内部には、デジタルカメラ３００における撮像処理などの機能を実現する電子部材の少なくとも一部をなす制御部９が収容されている。なお、外装材３の構成や組立方法等は、上記実施の形態１における外装材１の構成や組立方法等とそれぞれ同じである。   The inside of the digital camera 300 has the same configuration as that of the digital camera 100 described above (see FIG. 3). That is, inside the exterior material 3 is accommodated a control unit 9 that constitutes at least a part of an electronic member that realizes a function such as an imaging process in the digital camera 300. The configuration and assembly method of the exterior material 3 are the same as the configuration and assembly method of the exterior material 1 in the first embodiment.

次に、以上の構成を有するカバー部材の加工方法を詳細に説明する。まず、カバー部材３１および３２の原材料となる木材を、予め圧縮によって減少する容積を加えた形態で無圧縮状態の無垢材５０から形取る。   Next, a method for processing the cover member having the above configuration will be described in detail. First, the wood used as the raw material of the cover members 31 and 32 is shaped from the uncompressed solid material 50 in a form in which a volume that is reduced by compression is added in advance.

図２１は、カバー部材３１および３２の原材料となる木材を無圧縮状態の無垢材５０から形取る状況を模式的に示す説明図である。外部材３１１または３２１の原材料となる木材５５は平板状をなし、その長手方向が無垢材５０の繊維方向Ｌに略平行となるように形取られた柾目材である。また、内部材３１２または３２２の原材料となる木材５６も平板状をなし、その長手方向が無垢材５０の繊維方向Ｌと略平行になるように形取られた柾目材である。木材５５および５６の肉厚はともにＲで等しく、木材５５の長手方向の長さは、木材５６の長手方向の長さより長い。   FIG. 21 is an explanatory diagram schematically showing a situation in which the wood that is the raw material of the cover members 31 and 32 is formed from the uncompressed solid material 50. The wood 55 as a raw material of the external material 311 or 321 is a grid material shaped so that the longitudinal direction thereof is substantially parallel to the fiber direction L of the solid material 50. Further, the wood 56 as a raw material of the inner member 312 or 322 is also a flat plate shape, and is a grid material shaped so that its longitudinal direction is substantially parallel to the fiber direction L of the solid material 50. The thicknesses of the timbers 55 and 56 are both equal to R, and the longitudinal length of the timber 55 is longer than the longitudinal length of the timber 56.

次に、形取った木材５５および５６を圧縮する（圧縮工程）。この圧縮工程では、圧縮を行う前に、木材５５および５６を高温高圧の水蒸気雰囲気中に所定時間放置する。その後、各木材に対して所定の二つの金型を用いることにより、水分を過剰に吸収して軟化した木材５５および５６をそれぞれ挟持、圧縮する。   Next, the shaped woods 55 and 56 are compressed (compression process). In this compression step, the woods 55 and 56 are left in a high-temperature and high-pressure steam atmosphere for a predetermined time before compression. Thereafter, by using two predetermined molds for each wood, the woods 55 and 56 softened by excessively absorbing moisture are sandwiched and compressed, respectively.

この圧縮工程によって木材５５の肉厚ｒ5（＜Ｒ）および木材５６の肉厚ｒ6（＜Ｒ）は、場所によらずほぼ均一となる。この実施の形態３では、木材５５の肉厚ｒ5と木材５６の肉厚ｒ6が等しくなるように圧縮工程を行う。このため、木材５５の圧縮率Ｃ5＝（Ｒ−ｒ5）／Ｒおよび木材５６の圧縮率Ｃ6＝（Ｒ−ｒ6）／Ｒは等しく、その値は０.５〜０.７程度である。なお、圧縮工程によって木材５５および５６の外縁に不要部分が形成された場合には、この不要部分を切削によって除去し、適当な端面処理を施す。 The thickness r 5 of the compression process timber 55 by (<R) and the thickness r 6 of the timber 56 (<R) is almost uniform regardless of the location. In the third embodiment, the compression process is performed so that the thickness r 5 of the wood 55 is equal to the thickness r 6 of the wood 56. Therefore, the compression rate C 5 = (R−r 5 ) / R of the wood 55 and the compression rate C 6 = (R−r 6 ) / R of the wood 56 are equal, and the value is about 0.5 to 0.7. It is. In addition, when an unnecessary part is formed in the outer edge of the timbers 55 and 56 by a compression process, this unnecessary part is removed by cutting and an appropriate end surface process is performed.

図２２は、上記圧縮工程で形成した外部材３１１と内部材３１２を乾燥させた後、その両部材を重ねて接着する接着工程の概要を示す説明図である。以下では、カバー部材３１の接着工程を説明するが、カバー部材３２の接着工程も同じである。   FIG. 22 is an explanatory view showing an outline of an adhesion process in which the outer member 311 and the inner member 312 formed in the compression process are dried and then both the members are overlapped and adhered. Below, although the adhesion process of the cover member 31 is demonstrated, the adhesion process of the cover member 32 is also the same.

この接着工程では、外部材３１１の内側面と内部材３１２の外側面のうち少なくとも一方の面に適量の接着剤を塗布することにより、両部材を接着し、カバー部材３１の原型を形成する。この接着工程においても、上記実施の形態１と同様、外部材３１１と内部材３１２を適確に接着するために適当な治具を用いてもよい。   In this bonding step, an appropriate amount of adhesive is applied to at least one of the inner surface of the outer member 311 and the outer surface of the inner member 312, thereby bonding both members to form a prototype of the cover member 31. Also in this bonding step, an appropriate jig may be used in order to bond the outer member 311 and the inner member 312 appropriately as in the first embodiment.

このようにして形成したカバー部材３１の原型に対し、開口部や切り欠きを切削または穿孔によって形成し、デジタルカメラ３００の外装材３の一部をなすカバー部材３１が完成する。完成したカバー部材３１の肉厚は、圧縮前の無垢材５０から形取った状態における二つの木材の肉厚の合計２Ｒの３０〜５０％程度となる。   The cover member 31 that forms part of the exterior material 3 of the digital camera 300 is completed by forming openings and notches in the original pattern of the cover member 31 thus formed by cutting or drilling. The thickness of the completed cover member 31 is about 30 to 50% of the total thickness 2R of the two pieces of wood in the state of being formed from the solid material 50 before compression.

この実施の形態３においては、一般に接着工程後の外部材と内部材の木目がほぼ揃っているため、外力が作用したり温度や湿度が変化することによって生じる外装材３の伸縮の態様が、互いに固着する外部材と内部材とでほぼ一致し、それらの部材内部に応力が溜まりにくくなる。この結果、外力が作用したり温度や湿度が変化したりしてもひずみを生じにくいという特有の効果を得ることができる。   In this Embodiment 3, since the grain of the outer member and the inner member after the bonding process is generally almost uniform, the expansion and contraction mode of the exterior material 3 caused by the external force acting or the temperature or humidity changing, The outer member and the inner member that are fixed to each other substantially coincide with each other, and stress is less likely to be accumulated inside those members. As a result, it is possible to obtain a specific effect that distortion hardly occurs even when an external force is applied or temperature or humidity is changed.

また、外部材と内部材の木目をほぼ揃えることによって、１枚の木材で成形した同形状の圧縮木製品と同等の特性を得ることができる。その一方で、外部材と内部材の繊維方向は略平行であるが、固着した後に両部材の木目が完全に一致することはないため、１枚の木材を用いて圧縮木製品を形成する場合に比べて強度の異方性を小さくし、より一様な強度を付与することができる。   Further, by substantially aligning the grain of the outer member and the inner member, it is possible to obtain the same characteristics as the compressed wooden product of the same shape formed from a single piece of wood. On the other hand, the fiber direction of the outer member and the inner member is substantially parallel, but the grain of both members does not completely match after being fixed, so when forming a compressed wood product using a single piece of wood Compared to the strength anisotropy, more uniform strength can be provided.

なお、この実施の形態３で用いる木材は、外部材と内部材の木目がほぼ揃っていれば必ずしも柾目材である必要はなく、板目材、木口材、または追柾材を用いて実現することも可能である。   Note that the wood used in the third embodiment is not necessarily a grid material as long as the outer member and the inner member have substantially the same grain, and is realized by using a plate material, a wood end material, or a memorial material. It is also possible.

以上説明した本発明の実施の形態３によれば、２枚の木材を個別に圧縮した後、この２枚の木材を重ねて接着することにより、圧縮工程時における木材の肉厚を薄くすることができ、成形が容易になる。   According to the third embodiment of the present invention described above, after compressing two pieces of wood individually, the two pieces of wood are stacked and bonded, thereby reducing the thickness of the wood during the compression process. Can be formed easily.

また、この実施の形態３によれば、圧縮によって強度が強い層と弱い層とが交互に現れるため（図１３を参照）、靭性も備えた強くてしなやかな圧縮木製品を提供することができる。   Further, according to the third embodiment, a strong layer and a weak layer appear alternately by compression (see FIG. 13), so that a strong and supple compressed wood product having toughness can be provided.

さらに、この実施の形態３によれば、外部材と内部材の木目がほぼ一致するように重ねて接着するため、加工後の外部材と内部材の伸縮の態様がほぼ一致し、それらの部材内部に応力が溜まりにくくなる。したがって、外部から力が加わったり温度や湿度の変化があったりしてもひずみを生じにくい。   Further, according to the third embodiment, since the outer member and the inner member are overlapped and bonded so that the grain of the inner member substantially coincides, the expansion and contraction modes of the outer member and the inner member after processing substantially coincide with each other. Stress is less likely to accumulate inside. Therefore, even if a force is applied from the outside or a change in temperature or humidity occurs, distortion hardly occurs.

また、この実施の形態３によれば、木目を揃えることによって１枚で成形する場合と同等の特性を得ることができる一方で、重ねた部材の木目が完全に一致することはないので、１枚の木材を加工して圧縮木製品を形成する場合よりも強度の異方性を小さくすることができ、より一様な強度が得られる。   Further, according to the third embodiment, the same characteristics as in the case of molding by one piece can be obtained by aligning the grain, but the grain of the stacked members does not completely coincide with each other. The anisotropy of strength can be made smaller than when a piece of wood is processed to form a compressed wood product, and a more uniform strength can be obtained.

（実施の形態４）
図２３は、本発明の実施の形態４に係る木材の加工方法における接着工程の概要を説明する図である。同図に示す場合、同じ圧縮率で圧縮した外部材４１１と内部材４１２の間に補強材４１３を挟んで接着を行う。外部材４１１と内部材４１２を形成する圧縮工程は、上記実施の形態１〜３と同様である。 (Embodiment 4)
FIG. 23 is a diagram for explaining the outline of the bonding step in the wood processing method according to Embodiment 4 of the present invention. In the case shown in the drawing, the reinforcing member 413 is sandwiched between the outer member 411 and the inner member 412 which are compressed at the same compression rate, and the bonding is performed. The compression process for forming the outer member 411 and the inner member 412 is the same as in the first to third embodiments.

なお、図２３では外部材４１１と内部材４１２の木目や繊維方向を明示していない。これは、本実施の形態４に係る木材の加工方法が、外部材４１１や内部材４１２をなす木材の木目や繊維方向によらずに実施可能なためである。   In FIG. 23, the grain and fiber direction of the outer member 411 and the inner member 412 are not clearly shown. This is because the wood processing method according to the fourth embodiment can be carried out regardless of the grain or fiber direction of the wood forming the outer member 411 and the inner member 412.

補強材４１３は、例えばセルロース等の木材繊維成分を含む天然繊維である木綿、麻、亜麻等や、再生セルロース繊維であるレーヨン等を用いて形成される。より具体的には、補強材４１３は、均一な線状をなす複数の繊維を一様な方向に密に揃えたものを束ねることによって形成される。このような補強材４１３の繊維方向が、木材の繊維方向と交差してその木材の強度が弱い方向を指向するようにすれば、加工後の圧縮木材の曲げ強度および引張り強度とも向上させることができる。   The reinforcing material 413 is formed using, for example, cotton, hemp, flax, etc., which are natural fibers containing a wood fiber component such as cellulose, or rayon, which is a regenerated cellulose fiber. More specifically, the reinforcing material 413 is formed by bundling together a plurality of fibers that form a uniform line and are closely aligned in a uniform direction. If the fiber direction of such a reinforcing material 413 crosses the fiber direction of the wood and points in a direction where the strength of the wood is weak, both the bending strength and the tensile strength of the compressed wood after processing can be improved. it can.

一例をあげると、外部材４１１および内部材４１２が実施の形態１の外部材１１１および内部材１１２と同様の柾目材である場合、外部材４１１の繊維方向はカバー部材４１の長手方向に略平行であり、内部材４１２の繊維方向はカバー部材４１の短手方向に略平行となる。そこで、補強材４１３の繊維方向を外部材４１１および内部材４１２の繊維方向と４５度程度の角度で交差するように両部材間で配設すれば、外部材４１１と内部材４１２を重ねたときに強度が相対的に弱い方向を補強することができる。   For example, when the outer member 411 and the inner member 412 are the same mesh material as the outer member 111 and the inner member 112 of the first embodiment, the fiber direction of the outer member 411 is substantially parallel to the longitudinal direction of the cover member 41. The fiber direction of the inner member 412 is substantially parallel to the short direction of the cover member 41. Therefore, when the outer member 411 and the inner member 412 are overlapped with each other so that the fiber direction of the reinforcing member 413 intersects the fiber direction of the outer member 411 and the inner member 412 at an angle of about 45 degrees. The direction in which the strength is relatively weak can be reinforced.

図２４は、接着工程によって完成したカバー部材４１の構成を示す斜視図であり、図２５は図２４のＤ−Ｄ線断面図である。これらの図２４および図２５に示すように、補強材４１３は、外部材４１１と内部材４１２の間に配設されるため、その一部が外部材４１１と４１２の表面にそれぞれ若干食い込んでいるが、補強材４１３の主成分は木材が含有する成分と同じなので、木材との親和性が高い。この結果、木材自体の繊維を切断等によって傷つけたりすることなく、木材になじんだ状態で木材の表面に接着する。   24 is a perspective view showing the configuration of the cover member 41 completed by the bonding process, and FIG. 25 is a sectional view taken along the line DD of FIG. As shown in FIGS. 24 and 25, the reinforcing member 413 is disposed between the outer member 411 and the inner member 412, so that a part thereof slightly bites into the surfaces of the outer members 411 and 412. However, since the main component of the reinforcing material 413 is the same as the component contained in the wood, the affinity for the wood is high. As a result, the fiber of the wood itself is adhered to the surface of the wood without being damaged by cutting or the like in a state familiar to the wood.

また、カバー部材４１に外力が作用したり温度や湿度が変化したりする場合には、補強材４１３がカバー部材４１に追随して変形し、カバー部材４１の過度の変形を防止することができる。これは、補強材４１３の主成分が木材の含有する成分と同じであり、補強材４１３のヤング率、熱膨張係数、および湿度膨張係数が、カバー部材４１のヤング率、熱膨張係数、および湿度膨張係数にそれぞれ近い値をとるためである。   Further, when an external force is applied to the cover member 41 or the temperature or humidity changes, the reinforcing member 413 is deformed following the cover member 41, and excessive deformation of the cover member 41 can be prevented. . This is because the main component of the reinforcing material 413 is the same as the component contained in the wood, and the Young's modulus, thermal expansion coefficient, and humidity expansion coefficient of the reinforcing material 413 are the same as the Young's modulus, thermal expansion coefficient, and humidity of the cover member 41. This is because the values are close to the expansion coefficients.

なお、補強材４１３の繊維方向は必ずしも一様に揃っている必要はなく、その繊維方向がランダムであってもよい。また、線状の繊維をネット状に編むことによって補強材を形成してもよい。加えて、各々の繊維の長さも均一でなくてよく、絹や麻などから成る極薄の布や不織布等を用いて補強材４１３を形成してもよい。   Note that the fiber directions of the reinforcing material 413 are not necessarily uniform, and the fiber directions may be random. Further, the reinforcing material may be formed by knitting linear fibers into a net shape. In addition, the length of each fiber may not be uniform, and the reinforcing material 413 may be formed using an extremely thin cloth or non-woven fabric made of silk or hemp.

また、補強材４１３の素材は木材繊維成分を含むものに限られるわけではない。例えば、補強材４１３としてカーボン繊維を用いてもよいし、適当な素材に所定の繊維を貼付することによって補強材４１３を形成してもよい。また、金属シートや金属ネットを用いて補強材４１３を形成することもできる。   Further, the material of the reinforcing material 413 is not limited to one containing a wood fiber component. For example, carbon fibers may be used as the reinforcing material 413, or the reinforcing material 413 may be formed by sticking predetermined fibers to an appropriate material. Further, the reinforcing material 413 can be formed using a metal sheet or a metal net.

上記の如く形成されたカバー部材４１は、同様に形成される別のカバー部材（図示せず）と組み合わさって電子機器の外装材をなす。その電子機器がデジタルカメラである場合の外装材の構成や組立方法等は、補強材４１３の有無を除いて上記実施の形態１におけるデジタルカメラ１００の外装材１の構成や組立方法等とそれぞれ同じである（図１〜図３を参照）。   The cover member 41 formed as described above is combined with another cover member (not shown) formed in the same manner as an exterior material of the electronic device. When the electronic device is a digital camera, the configuration and the assembly method of the exterior material are the same as the configuration and the assembly method of the exterior material 1 of the digital camera 100 in Embodiment 1 except for the presence or absence of the reinforcing material 413. (See FIGS. 1 to 3).

以上説明した本発明の実施の形態４によれば、成形が容易であるとともに、表面に沿った方向に対して一様な強度を付与することができる。   According to the fourth embodiment of the present invention described above, molding is easy and uniform strength can be imparted in the direction along the surface.

また、この実施の形態４によれば、カバー部材（圧縮木製品）をなす外部材と内部材の間に補強材を設けることにより、そのカバー部材の強度を一段と向上させることができる。   Further, according to the fourth embodiment, the strength of the cover member can be further improved by providing the reinforcing material between the outer member and the inner member forming the cover member (compressed wood product).

特に、木材繊維成分を含んで成る補強材を用いることにより、木材と補強材との収縮率が略同一となり、木材との親和性が高く、材質の均一化を図ることができる。また、そのような補強材は、木材自体の繊維を切断したりすることがないため、木材自体の強度を劣化させることなく、圧縮木製品としてのカバー部材の強度を一段と向上させることができる。   In particular, by using a reinforcing material containing a wood fiber component, the contraction rate between the wood and the reinforcing material is substantially the same, the affinity with the wood is high, and the material can be made uniform. In addition, since such a reinforcing material does not cut the fibers of the wood itself, the strength of the cover member as a compressed wood product can be further improved without deteriorating the strength of the wood itself.

ところで、補強材を外部材の外側表面および内部材の内側表面の一方または両方に設けることも可能である。補強材を外部材の外側表面に設ける場合には、圧縮木製品の強度を向上させるとともに、その補強材自体がデザインの一部となって一段と個性的な製品を提供することができる。これに対して、補強材を内部材の内側表面に設ける場合には、外観に影響を及ぼさずに圧縮木製品の強度を向上させることができる。   By the way, it is also possible to provide the reinforcing material on one or both of the outer surface of the outer member and the inner surface of the inner member. When the reinforcing material is provided on the outer surface of the outer member, the strength of the compressed wood product can be improved, and the reinforcing material itself can be part of the design to provide a more unique product. On the other hand, when the reinforcing material is provided on the inner surface of the inner member, the strength of the compressed wood product can be improved without affecting the appearance.

なお、３枚以上の木材を用いて圧縮木製品を製造する場合には、隣接する木材間の少なくともいずれか一つの木材間に補強材を配設すればよい。   In addition, what is necessary is just to arrange | position a reinforcing material between at least any one wood between adjacent timber, when manufacturing a compressed wood product using three or more timber.

（その他の実施の形態）
ここまで、本発明を実施する上で最良と思われる形態を、実施の形態１〜４として詳述してきたが、本発明はこれらの実施の形態によってのみ限定されるものではない。以下、その他の実施の形態を説明する。 (Other embodiments)
Up to this point, the best mode for carrying out the present invention has been described in detail as the first to fourth embodiments. However, the present invention is not limited only to these embodiments. Hereinafter, other embodiments will be described.

（１）カバー部材を構成する外部材と内部材の間に電子機能部材を配設することもできる。例えば、この電子機能部材として外部材と内部材の間にアース回路基板を挿入し、外装材内部の電子部材と接続すれば、外装材内部に本来設けるべきアース回路用の空間を節約することができる。また、別の電子機能部材として、金属シートを外部材と内部材の間に設けることにより、補強材としての機能に加えて電磁波を防止するシールド部材としての機能を兼備させることができる。さらに別の電子機能部材として、ＩＣチップや各種実装部品を組み込んだシートまたはフレキシブル基板等を挿入することにより、多様な機能を備えた電子機器を実現することが可能となる。 (1) An electronic functional member may be disposed between an outer member and an inner member that constitute the cover member. For example, if an earth circuit board is inserted between the outer member and the inner member as the electronic functional member and connected to the electronic member inside the exterior material, the space for the ground circuit that should be originally provided inside the exterior material can be saved. it can. Further, as another electronic functional member, by providing a metal sheet between the outer member and the inner member, in addition to a function as a reinforcing material, a function as a shield member for preventing electromagnetic waves can be provided. Furthermore, an electronic device having various functions can be realized by inserting a sheet or a flexible substrate in which an IC chip or various mounting components are incorporated as another electronic functional member.

なお、３枚以上の木材を用いてカバー部材を形成する場合には、補強材や電子機能部材を配設する場所が複数あるので、カバー部材の用途に応じて、それらの部材を組み合わせて配設してもよい。   In addition, when the cover member is formed using three or more pieces of wood, there are a plurality of places where the reinforcing material and the electronic functional member are provided. Therefore, these members are combined and arranged according to the use of the cover member. You may set up.

（２）図２６は、外部材と内部材とで肉厚を変えて圧縮加工を行った圧縮木製品としてのカバー部材の構成を示す断面図である。ここでは、外部材４５１と内部材４５２の圧縮率は同一とする。図２６に示す場合、カバー部材４５は、外部材４５１の肉厚ｈ1が内部材４５２の肉厚ｈ2よりも小さい（ｈ1＜ｈ2）。したがって、相対的に肉厚が小さい外部材４５１として板目材や木口材のような割れやすく成形が難しい木材を用いることができ、圧縮工程における加工が容易となって割れ等を防止することができる。 (2) FIG. 26 is a cross-sectional view showing a configuration of a cover member as a compressed wood product that has been compressed by changing the thickness between the outer member and the inner member. Here, the compression rates of the outer member 451 and the inner member 452 are the same. In the case shown in FIG. 26, the cover member 45 has a thickness h 1 of the outer member 451 smaller than a thickness h 2 of the inner member 452 (h 1 <h 2 ). Therefore, as the outer member 451 having a relatively small thickness, it is possible to use wood that is easily cracked and difficult to be molded, such as a plate material or a mouthpiece material, which facilitates processing in the compression process and prevents cracking and the like. it can.

この場合には、内部材として強度の高い柾目材等を用いることにより、カバー部材４５自体の肉厚は同一でも、強度の高い方の部材の肉厚を厚くした分だけ強度を向上させることができる。なお、平板状の木材からの曲げ等の加工において、圧縮工程における変形の度合が外部材と内部材とで異なる場合には、変形の度合が大きい方の肉厚を薄くし、成形しやすい方を厚くしてもよい。   In this case, the strength of the cover member 45 itself can be increased by increasing the thickness of the higher strength member even if the thickness of the cover member 45 itself is the same by using a high strength mesh material as the inner member. it can. If the degree of deformation in the compression process is different between the outer member and the inner member in processing such as bending from flat wood, the one with the greater degree of deformation is made thinner and easier to mold May be thickened.

（３）圧縮工程における金型の形状や木材の肉厚を調整することにより、外部材と内部材の圧縮率を部材ごとに変える。同じ種類の木材の場合、その木材の圧縮後の色調は圧縮率によって異なる。より具体的には、圧縮率が相対的に大きい木材の方が炭化が進むため、圧縮によって表面の色がより濃く変化する。また、圧縮率が相対的に大きい木材の方が、表面の平滑性や光沢に優れ、汚れにくい。 (3) The compression ratio of the outer member and the inner member is changed for each member by adjusting the shape of the mold and the thickness of the wood in the compression step. In the case of the same kind of wood, the color tone after compression of the wood varies depending on the compression ratio. More specifically, since the wood having a relatively high compression rate is carbonized, the color of the surface changes more strongly due to compression. In addition, wood having a relatively high compression rate is superior in surface smoothness and gloss, and is less likely to get dirty.

これに対して、圧縮率が相対的に小さい木材は、圧縮率が相対的に大きい木材よりも表面の色の変化が少ないが、より軟らかい。また、圧縮率が相対的に小さい木材の方が木の風合いが残っていて手触りもよい。このような特徴に鑑みて、適用する製品に付与したいデザインやその製品の特性に応じた圧縮率を設定すれば、多様な色調を有する個性的な圧縮木製品を形成することができる。   In contrast, wood with a relatively low compression rate has less surface color change than wood with a relatively high compression rate, but is softer. In addition, wood with a relatively small compression rate has a texture of wood and is easy to touch. In view of such characteristics, by setting a compression ratio according to the design to be applied to the product to be applied and the characteristics of the product, individual compressed wood products having various colors can be formed.

一例をあげると、木口材のように曲げ等による成形が難しい材質に対しては圧縮率を小さくする一方、柾目材のように成形が容易な材質に対しては圧縮率を大きくすれば、それらを重ねて圧縮して成る圧縮木製品を容易に成形することができる。したがって、異なる圧縮率の木材を組み合わせて用いることにより、製品の色調や外観を多様に変化させながらも、適正な強度を保つことが可能となる。   For example, if the compression ratio is reduced for materials that are difficult to be formed by bending, such as a lip material, the compression ratio can be increased for materials that are easy to mold, such as a mesh material. It is possible to easily form a compressed wood product formed by stacking and compressing. Therefore, by using a combination of woods having different compression ratios, it is possible to maintain an appropriate strength while variously changing the color tone and appearance of the product.

ところで、木材の圧縮率がその木材の限界圧縮率を超えない範囲で十分高い場合には、色調が変化するだけでなく、金型温度が高温であるために焼成によって木材が炭化して導電体となり、電磁シールド効果を生じる。このため、本発明に係る木材の加工方法を用いて得られる圧縮木製品を電子機器の外装材として適用する場合には、高い圧縮率によって導電体となった木材と、炭化しないで絶縁体のままである木材とを重ねて外装材を構成すればより好ましい。このためには、圧縮工程において、外部材と内部材の対向する面のうち少なくとも一方の面を炭化すればよい。   By the way, when the compressibility of the wood is sufficiently high as long as it does not exceed the limit compressibility of the wood, not only the color tone changes, but the wood is carbonized by firing because the mold temperature is high, and the conductor Thus, an electromagnetic shielding effect is produced. For this reason, when the compressed wood product obtained by using the wood processing method according to the present invention is applied as an exterior material of an electronic device, it remains as an insulator without being carbonized with wood that has become a conductor due to a high compression ratio. It is more preferable if the exterior material is constituted by overlapping the wood. For this purpose, at least one of the opposing surfaces of the outer member and the inner member may be carbonized in the compression step.

（４）以上の説明では、原材料の無垢材として同一種類の木材を用いることを前提としていたが、各層で木材の種類を変えてもよい。例えば、２枚の木材を重ねて電子機器のカバー部材を形成する場合、外部材としてデザインを重視して意匠性の高い見栄えのよい木材を選択する一方、内部材は強度を重視して強度の高い木材を適用できればより好ましい。このように異なる種類の木材をうまく組み合わせることにより、１枚の木材からでは決して実現することのできない強度と美観を兼ね備えた圧縮木製品を提供することができる。 (4) In the above description, it is assumed that the same kind of wood is used as a solid raw material, but the kind of wood may be changed in each layer. For example, when a cover member for an electronic device is formed by stacking two pieces of wood, the design of the outer member is emphasized and a good-looking wood with high design is selected, while the inner member emphasizes the strength of the strength. It is more preferable if high wood can be applied. Thus, by properly combining different kinds of wood, it is possible to provide a compressed wood product having strength and beauty that can never be realized from a single piece of wood.

なお、この場合にも、外部材や内部材として用いる木材の加工の難易度に応じて各部材の肉厚や圧縮率を上記同様に調整することができる。   In this case as well, the thickness and compression rate of each member can be adjusted in the same manner as described above according to the difficulty of processing the wood used as the outer member and the inner member.

（５）所定の三次元形状をなすように無垢材からの形取りを行ってもよい。この場合、木材を形取る段階で開口部や切り欠きを一緒に形成してもよいし、木材を形取った後でそれらの開口部や切り欠きを切削や穿孔等によって形成してもよい。 (5) You may shape from a solid material so that a predetermined three-dimensional shape may be made. In this case, the openings and notches may be formed together at the stage of shaping the wood, or the openings and notches may be formed by cutting or drilling after shaping the wood.

（６）本発明に係る木材の加工方法によって形成された圧縮木製品を外装材として適用し得る電子機器は、デジタルカメラの他に、携帯電話またはＰＨＳまたはＰＤＡ等の携帯型通信端末、ＭＤまたはＣＤまたはカセットテープ等の音声記録媒体を装着して音声を出力する携帯型オーディオ装置、ＩＣレコーダ、携帯型テレビ、携帯型ラジオ、各種家電製品のリモコン、デジタルビデオなどがある。また、本発明に係る圧縮木製品は、電子機器の外装材以外の用途にも適用可能である。 (6) An electronic apparatus to which the compressed wood product formed by the wood processing method according to the present invention can be applied as an exterior material is a mobile phone, a portable communication terminal such as PHS or PDA, MD or CD, in addition to a digital camera. Alternatively, there are portable audio devices that output sound by mounting an audio recording medium such as a cassette tape, IC recorders, portable televisions, portable radios, remote controls for various home appliances, digital video, and the like. In addition, the compressed wood product according to the present invention is applicable to uses other than the exterior material of the electronic device.
