Description

本発明は電子機器についての技術分野に関する。詳しくは、トレイの背面に弾性部材を取り付けると共に外筐に弾性部材が押し付けられるリブを設けて構造の簡素化等を確保した上で密閉性の向上を図る技術分野に関する。 The present invention relates to the technical field of electronic equipment. More specifically, the present invention relates to a technical field in which an elastic member is attached to the back surface of a tray and a rib for pressing the elastic member is provided on an outer casing to ensure the simplification of the structure and improve the sealing performance.

各種の電子機器、例えば、ディスク状記録媒体に対する情報信号の記録や再生を行うディスクドライブ装置には、外筐に挿入自在及び引出自在に支持されディスク状記録媒体を外筐の内外において搬送するトレイを備えたものがある。 Various electronic devices, for example, disk drive devices for recording and reproducing information signals to and from a disk-shaped recording medium, are supported so that they can be inserted into and pulled out from an outer casing, and a tray that carries the disk-shaped recording medium inside and outside the outer casing. There is something with.

このようなトレイを有するディスクドライブ装置にあっては、外筐に形成されたトレイ挿脱孔から外筐の内部への塵埃等の侵入を防止してディスク状記録媒体に対する情報信号の記録動作や再生動作の信頼性の向上を図るために、トレイが外筐に引き込まれた状態においてトレイと外筐との間の密閉性を確保する必要がある。 In a disk drive device having such a tray, the operation of recording information signals on a disk-shaped recording medium by preventing entry of dust and the like from the tray insertion / removal hole formed in the outer casing into the inner casing, In order to improve the reliability of the reproducing operation, it is necessary to ensure the sealing between the tray and the outer casing in a state where the tray is pulled into the outer casing.

従来のディスクドライブ装置には、トレイと外筐との間の密閉性を確保するために、トレイの蓋部の背面側にバネ部材を有する付勢機構を設け、トレイが引き込まれたときに付勢機構によって蓋部を引込方向へ付勢して蓋部を外筐の外面に押し付けてトレイ挿脱孔を閉塞するようにしたものがある（例えば、特許文献１参照）。 A conventional disk drive device is provided with a biasing mechanism having a spring member on the back side of the lid portion of the tray in order to ensure the tightness between the tray and the outer casing, and is attached when the tray is retracted. There is a mechanism in which a lid portion is urged in a retracting direction by a biasing mechanism and the lid portion is pressed against an outer surface of an outer casing to close a tray insertion / removal hole (see, for example, Patent Document 1).

特開平２００４−１２７３３７号公報Japanese Patent Laid-Open No. 2004-127337

ところが、特許文献１に記載された電子機器にあっては、バネ部材を有する付勢機構を設けてトレイを外筐に押し付けてトレイと外筐との間の密閉性を確保しているため、付勢機構を有する分、機構が複雑となり製造コストの増大を来たすと言う問題がある。 However, in the electronic device described in Patent Document 1, an urging mechanism having a spring member is provided to press the tray against the outer casing to ensure the sealing between the tray and the outer casing. Since the urging mechanism is provided, there is a problem that the mechanism becomes complicated and the manufacturing cost increases.

また、トレイの蓋部の背面側に付勢機構を配置するためのスペースが必要となり、その分、トレイの移動方向における長さが長くなり、ディスクドライブ装置の大型化を来たすと言う問題もある。 In addition, a space for arranging the urging mechanism on the back side of the lid portion of the tray is required, and the length in the moving direction of the tray is correspondingly increased, resulting in an increase in the size of the disk drive device. .

そこで、本発明電子機器は、構造の簡素化等を確保した上で密閉性の向上を図ることを課題とする。 Therefore, an object of the electronic device of the present invention is to improve hermeticity while ensuring simplification of the structure and the like.

本発明電子機器は、外筐にトレイが移動されるトレイ挿脱孔を形成し、トレイに、記録媒体が装填される記録媒体装填部と引込位置において外筐のトレイ挿脱孔を閉塞する蓋部とを設け、トレイの蓋部の背面における記録媒体装填部の周囲の位置に枠状に形成された弾性部材を取り付け、外筐に、トレイが引込位置に移動されたときに弾性部材が押し付けられ該弾性部材を弾性変形させると共に枠状に形成され弾性部材側へ突出されたリブを設けたものである。 The electronic apparatus according to the present invention has a tray insertion / removal hole for moving the tray in the outer casing, a recording medium loading portion for loading the recording medium on the tray, and a lid for closing the tray insertion / removal hole of the outer casing at the retracted position. A frame-shaped elastic member is attached to a position around the recording medium loading portion on the back of the lid portion of the tray, and the elastic member is pressed against the outer casing when the tray is moved to the retracted position. The elastic member is elastically deformed and provided with a rib that is formed in a frame shape and protrudes toward the elastic member.

従って、本発明電子機器にあっては、引込位置において、トレイに取り付けられた弾性部材が外筐に設けられたリブに押し付けられる。 Therefore, in the electronic device of the present invention, the elastic member attached to the tray is pressed against the rib provided in the outer casing at the retracted position.

本発明電子機器は、外筐に挿入自在及び引出自在に支持され記録媒体を外筐の内外において搬送するトレイを備え該トレイが外筐の内部に引き込まれた引込位置と外筐から外部へ引き出された引出位置との間で移動される電子機器であって、外筐にトレイが移動されるトレイ挿脱孔を形成し、トレイに、記録媒体が装填される記録媒体装填部と引込位置において外筐のトレイ挿脱孔を閉塞する蓋部とを設け、トレイの蓋部の背面における記録媒体装填部の周囲の位置に枠状に形成された弾性部材を取り付け、外筐に、トレイが引込位置に移動されたときに弾性部材が押し付けられ該弾性部材を弾性変形させると共に枠状に形成され弾性部材側へ突出されたリブを設けたことを特徴とする。 The electronic apparatus according to the present invention includes a tray that is supported so as to be freely inserted into and withdrawn from the outer casing and conveys a recording medium inside and outside the outer casing, and a drawing position in which the tray is drawn into the outer casing and the outside from the outer casing. An electronic device that is moved between the drawer position, a tray insertion / removal hole for moving the tray is formed in the outer casing, and a recording medium loading unit in which the recording medium is loaded on the tray and the drawing position A lid that closes the tray insertion / removal hole of the outer casing is provided, and an elastic member formed in a frame shape is attached to a position around the recording medium loading section on the back of the lid of the tray, and the tray is pulled into the outer casing. The elastic member is pressed when moved to a position to elastically deform the elastic member, and a rib formed in a frame shape and protruding toward the elastic member is provided.

従って、弾性部材を外筐に設けられたリブに押し付けてトレイと外筐との間の密閉性が確保され、バネ部材を有する付勢機構等の複雑な機構を配置する必要がなく、機構の簡素化及び配置スペースの低減による小型化を図ることができる。 Therefore, the elastic member is pressed against the rib provided on the outer casing to ensure the sealing between the tray and the outer casing, and it is not necessary to arrange a complicated mechanism such as a biasing mechanism having a spring member. Miniaturization can be achieved by simplification and reduction of the arrangement space.

請求項２に記載した発明にあっては、リブを弾性部材に近付くに従って先細りとなる形状に形成したので、弾性部材が小さな引込力で確実にリブによって圧縮され、トレイと外筐との間の良好な密閉性を確保することができる。 In the invention described in claim 2, since the rib is formed in a shape that tapers as it approaches the elastic member, the elastic member is reliably compressed by the rib with a small pulling force, and the space between the tray and the outer casing is reduced. Good hermeticity can be secured.

請求項３に記載した発明にあっては、トレイが引込位置に移動されたときにリブによって弾性変形される弾性部材の変形量を、弾性部材の厚みに対する５％乃至３０％にしたので、小さな引込力によってトレイを引込位置まで移動させることができる。 In the invention described in claim 3, the amount of deformation of the elastic member elastically deformed by the rib when the tray is moved to the retracted position is set to 5% to 30% of the thickness of the elastic member. The tray can be moved to the retracted position by the retracting force.

請求項４に記載した発明にあっては、トレイが引込位置に移動され弾性部材がリブに押し付けられた状態において、外筐の外面と弾性部材との間に隙間が形成されるようにしたので、小さな引込力によってトレイと外筐との間の安定した密閉状態を確保することができる。 In the invention described in claim 4, since the gap is formed between the outer surface of the outer casing and the elastic member in a state where the tray is moved to the retracted position and the elastic member is pressed against the rib. A stable sealing state between the tray and the outer casing can be ensured by a small pulling force.

以下に、本発明電子機器を実施するための最良の形態を添付図面に従って説明する。 The best mode for carrying out the electronic apparatus of the present invention will be described below with reference to the accompanying drawings.

以下に示した最良の形態は、本発明電子機器を、ディスク状記録媒体に対する情報信号の記録及び再生を行うディスクドライブ装置に適用したものである。尚、本発明電子機器の適用範囲はディスクドライブ装置に限られることはなく、記録媒体を外筐の内外で搬送するトレイを備えた他の各種の電子機器に広く適用することができる。 In the best mode described below, the electronic apparatus of the present invention is applied to a disk drive device that records and reproduces information signals on a disk-shaped recording medium. The applicable range of the electronic apparatus of the present invention is not limited to the disk drive device, and can be widely applied to various other electronic apparatuses having a tray for conveying a recording medium inside and outside the outer casing.

電子機器（ディスクドライブ装置）１は、外筐２内に所要の各部が配置されて成る（図１参照）。 The electronic device (disk drive device) 1 is configured by arranging required parts in an outer casing 2 (see FIG. 1).

外筐２は、例えば、扁平な箱状に形成され、前方に開口する箱状に形成された本体パネル３と該本体パネル３の前端部に取り付けられたフロントパネル４とを有している。 The outer casing 2 is formed in, for example, a flat box shape, and has a main body panel 3 formed in a box shape opening forward and a front panel 4 attached to a front end portion of the main body panel 3.

フロントパネル４は後方に開口された横長の箱状に形成されている。フロントパネル４の内部には操作釦５、５、・・・の一部を除いた部分が配置され、該操作釦５、５、・・・の一部がフロントパネル４の前面部４ａから前方へ突出されている。 The front panel 4 is formed in a horizontally long box shape opened rearward. A part of the front panel 4 excluding a part of the operation buttons 5, 5,... Is arranged, and a part of the operation buttons 5, 5,. It is protruded to.

フロントパネル４の前面部４ａには前方に開口された横長の配置凹部６が形成されている（図１乃至図３参照）。配置凹部６の底面部６ａにはトレイ挿脱孔７が形成されている。トレイ挿脱孔７は内径が配置凹部６の開口面積より小さい横長の矩形状に形成され、外筐２の内部に連通されている。 A front-side portion 4a of the front panel 4 is formed with a horizontally-arranged concave portion 6 opened forward (see FIGS. 1 to 3). A tray insertion / removal hole 7 is formed in the bottom surface portion 6 a of the arrangement recess 6. The tray insertion / removal hole 7 is formed in a horizontally long rectangular shape whose inner diameter is smaller than the opening area of the arrangement recess 6, and communicates with the inside of the outer casing 2.

配置凹部６にはトレイ挿脱孔７の前側開口縁に連続して前方へ突出されたリブ８が設けられている（図２及び図３参照）。リブ８はトレイ挿脱孔７の前側開口縁の全周に設けられ、前方へ行くに従って幅が細くなる先細りの形状に形成されている。リブ８は、図２に示すように、例えば、前方を向く先端面８ａと該先端面８ａの内縁から後方へ延びる水平面８ｂと先端面８ａから後方へ行くに従って水平面８ｂから遠ざかるように傾斜された傾斜面８ｃとを有している。 The arrangement recess 6 is provided with a rib 8 projecting forward from the front opening edge of the tray insertion / removal hole 7 (see FIGS. 2 and 3). The rib 8 is provided on the entire circumference of the front opening edge of the tray insertion / removal hole 7 and is formed in a tapered shape whose width becomes narrower toward the front. As shown in FIG. 2, for example, the rib 8 is inclined so as to move away from the horizontal surface 8b as it goes backward from the front end surface 8a, the horizontal surface 8b extending rearward from the inner edge of the front end surface 8a, and the rear end surface 8a. And an inclined surface 8c.

尚、リブは先端面と水平面と傾斜面を有する形状に限られることはなく、先細りの形状であれば任意の形状に形成することが可能であり、例えば、図４に示すリブ８Ａのような先端が丸みを帯びた形状、図５に示すリブ８Ｂのような外側の面が水平面とされ内側の面が傾斜面とされた形状、図６に示すリブ８Ｃのような先端面の両側に連続する面が傾斜面として形成された形状等としてもよい。 The rib is not limited to a shape having a tip surface, a horizontal surface, and an inclined surface, and can be formed in any shape as long as it is a tapered shape. For example, the rib 8A shown in FIG. A shape with a rounded tip, a shape in which the outer surface such as the rib 8B shown in FIG. 5 is a horizontal surface and an inner surface is an inclined surface, and is continuous on both sides of the tip surface such as the rib 8C shown in FIG. It is good also as the shape etc. in which the surface to perform was formed as an inclined surface.

外筐２にはトレイ挿脱孔７から引き出されるトレイ９が前後方向へ移動自在に支持されている（図１乃至図３参照）。トレイ９はディスク状記録媒体が装填される記録媒体装填部１０と該記録媒体装填部１０の前端部に取り付けられた蓋部１１とを有している。 A tray 9 drawn out from the tray insertion / removal hole 7 is supported on the outer casing 2 so as to be movable in the front-rear direction (see FIGS. 1 to 3). The tray 9 has a recording medium loading unit 10 on which a disk-shaped recording medium is loaded and a lid 11 attached to the front end of the recording medium loading unit 10.

記録媒体装填部１０にはディスク状記録媒体が装填される装填用凹部１０ａが形成されている。記録媒体装填部１０の前後方向から見た外形寸法は、トレイ挿脱孔７の開口縁との接触を防止して外筐２に対する良好な移動性を確保するために、トレイ挿脱孔７の内径より小さくされている（図２及び図３参照）。 The recording medium loading unit 10 is formed with a loading recess 10a into which a disk-shaped recording medium is loaded. The external dimensions of the recording medium loading unit 10 as viewed from the front and rear direction are such that the tray insertion / removal hole 7 has a dimension to prevent contact with the opening edge of the tray insertion / removal hole 7 and ensure good mobility with respect to the outer casing 2. It is smaller than the inner diameter (see FIGS. 2 and 3).

蓋部１１は、図７に示すように、横長の矩形の板状に形成された前面パネル部１２と該前面パネル部１２の背面１２ａから後方へ突出された結合用突部１３とが一体に形成されて成る。結合用突部１３は記録媒体装填部１０の前端部に結合されている。 As shown in FIG. 7, the lid 11 has a front panel portion 12 formed in a horizontally long rectangular plate shape and a coupling projection 13 that protrudes rearward from the back surface 12 a of the front panel portion 12. Formed. The coupling protrusion 13 is coupled to the front end of the recording medium loading unit 10.

前面パネル部１２の外形状は、配置凹部６の開口面積より小さくトレイ挿脱孔７の内径より大きくされている。 The outer shape of the front panel portion 12 is smaller than the opening area of the arrangement recess 6 and larger than the inner diameter of the tray insertion / removal hole 7.

前面パネル部１２の背面１２ａには横長の枠状に形成された弾性部材１４が取り付けられている。弾性部材１４は幅方向における中央部が、外筐２に設けられたリブ８に対向して位置されるように蓋部１１に取り付けられている（図２及び図３参照）。弾性部材１４はトレイ９が外筐２に引き込まれたときに、リブ８に押し付けられて一部が圧縮される。 An elastic member 14 formed in a horizontally long frame shape is attached to the back surface 12 a of the front panel portion 12. The elastic member 14 is attached to the lid portion 11 so that the central portion in the width direction is positioned opposite to the rib 8 provided in the outer casing 2 (see FIGS. 2 and 3). The elastic member 14 is pressed against the rib 8 and partially compressed when the tray 9 is pulled into the outer casing 2.

弾性部材１４としては、例えば、ポリウレタンフォームであるポロン（株式会社ノイアックコーポレーション製）が用いられている。弾性部材１４は、例えば、厚みが１．０ｍｍ乃至２．０ｍｍとされ、結合用突部１３を囲む位置に取り付けられている（図７参照）。 As the elastic member 14, for example, PORON (manufactured by Neuac Corporation), which is a polyurethane foam, is used. The elastic member 14 has a thickness of 1.0 mm to 2.0 mm, for example, and is attached to a position surrounding the coupling protrusion 13 (see FIG. 7).

尚、弾性部材１４として用いられる材料はポリウレタンフォームに限られることはなく、例えば、ＥＰＤＭ（エチレンープロピレンージエンゴム）、各種のゴム系の材料、ポリエチレンフォーム等を用いることも可能である。 The material used as the elastic member 14 is not limited to polyurethane foam, and for example, EPDM (ethylene-propylene-diene rubber), various rubber materials, polyethylene foam, and the like can be used.

図８は、弾性部材１４の一例として用いられたポロンの圧縮特性を示すグラフ図であり、物性の異なる４種類のポロンについて示している。横軸は弾性部材１４の圧縮率（厚みに対する圧縮量の割合）を示し、縦軸は弾性部材１４に付与された圧縮荷重を示す。 FIG. 8 is a graph showing the compression characteristics of poron used as an example of the elastic member 14, and shows four types of poron having different physical properties. The horizontal axis indicates the compression ratio (ratio of the compression amount with respect to the thickness) of the elastic member 14, and the vertical axis indicates the compression load applied to the elastic member 14.

何れの種類の弾性部材１４においても、約５０％の圧縮率を境として、これより大きくなると急激に圧縮荷重が大きくなることが解る。従って、トレイ９に弾性部材１４が取り付けられた場合においては、圧縮率が約５０％を境として、これより大きく弾性部材１４を圧縮しようとしたしたときには、トレイ９を外筐２の内部に引き込む引込力を急激に大きくする必要がある。 It can be seen that in any type of elastic member 14, the compression load suddenly increases when the compression ratio becomes higher than about 50% of the compression ratio. Therefore, when the elastic member 14 is attached to the tray 9, when the compression rate is about 50% and an attempt is made to compress the elastic member 14 larger than this, the tray 9 is pulled into the outer casing 2. It is necessary to increase the pulling force rapidly.

トレイ９が外筐２の内部に引き込まれた状態において、所定の操作釦（イジェクト・ローディング釦）５が操作されると、トレイ９が外筐２から引き出されて引出位置まで移動される（図３参照）。 When a predetermined operation button (eject / loading button) 5 is operated in a state in which the tray 9 is pulled into the outer casing 2, the tray 9 is pulled out from the outer casing 2 and moved to the pull-out position (FIG. 3).

引出位置に移動されたトレイ９の装着用凹部１０ａにディスク状記録媒体を装填し、再び、上記操作釦５が操作されると、トレイ９が後方へ移動され外筐２の内部へ引き込まれて行く。尚、トレイ９の外筐２に対する引出動作及び引込動作は、外筐２の内部に配置され搬送用モーターを有する図示しないトレイ搬送機構によって行われる。 When a disc-shaped recording medium is loaded in the mounting recess 10a of the tray 9 moved to the drawing position and the operation button 5 is operated again, the tray 9 is moved backward and pulled into the outer casing 2. go. Note that the drawing operation and the drawing operation of the tray 9 with respect to the outer casing 2 are performed by a tray transport mechanism (not shown) that is disposed inside the outer casing 2 and has a transport motor.

トレイ９が引き込まれていくと、引込位置まで移動されて弾性部材１４がリブ８に押し付けられ、弾性部材１４がリブ８に押し付けられた分だけ圧縮されリブ８の全周に密着されトレイ挿脱孔７が閉塞される（図２参照）。このとき弾性部材１４の圧縮量は、厚みの５％乃至５０％、望ましくは、５％乃至３０％になるように設定されている。 When the tray 9 is pulled in, the elastic member 14 is moved to the pull-in position, and the elastic member 14 is pressed against the rib 8. The elastic member 14 is compressed by the amount pressed against the rib 8, and is closely attached to the entire circumference of the rib 8. The hole 7 is closed (see FIG. 2). At this time, the compression amount of the elastic member 14 is set to be 5% to 50%, preferably 5% to 30% of the thickness.

また、引込位置において弾性部材１４がリブ８に密着された状態においては、弾性部材１４の幅方向における中央部がリブ８に押し付けられて圧縮される。このように弾性部材１４の幅方向における中央部がリブ８に押し付けられるような設定をすることにより、トレイ９の外筐２に対する位置精度がトレイ９の外筐２に対するガタツキ等により低下した場合においても、弾性部材１４をリブ８に確実に押し付けることができる。 Further, when the elastic member 14 is in close contact with the rib 8 at the retracted position, the central portion in the width direction of the elastic member 14 is pressed against the rib 8 and compressed. In this way, by setting the central portion of the elastic member 14 in the width direction to be pressed against the rib 8, the positional accuracy of the tray 9 with respect to the outer casing 2 is reduced due to rattling or the like of the tray 9 with respect to the outer casing 2. Also, the elastic member 14 can be reliably pressed against the rib 8.

引込位置においては、弾性部材１４の後面１４ａと外筐２の配置凹部６の底面部６ａとの間には一定の隙間が形成され、弾性部材１４がリブ８とのみ接触され底面部６ａとは非接触の状態とされている。このときトレイ９の蓋部１１は配置凹部６に位置され、蓋部１１がフロントパネル４の前面部４ａから前方に突出されない状態とされる。 In the retracted position, a certain gap is formed between the rear surface 14a of the elastic member 14 and the bottom surface portion 6a of the arrangement recess 6 of the outer casing 2, and the elastic member 14 is brought into contact only with the ribs 8 to define the bottom surface portion 6a. It is in a non-contact state. At this time, the lid portion 11 of the tray 9 is positioned in the arrangement recess 6, and the lid portion 11 is not projected forward from the front surface portion 4 a of the front panel 4.

以上に記載した通り、電子機器１にあっては、弾性部材１４を外筐２に設けられたリブ８に押し付けてトレイ９と外筐２との間の密閉性を確保しているため、トレイ９の蓋部１１の前面パネル部１２の背面１２ａ側にバネ部材を有する付勢機構等の複雑な機構を配置する必要がなく、機構の簡素化及び配置スペースの低減による小型化を図ることができる。 As described above, in the electronic device 1, the elastic member 14 is pressed against the rib 8 provided in the outer casing 2 to ensure the sealing between the tray 9 and the outer casing 2. It is not necessary to arrange a complicated mechanism such as an urging mechanism having a spring member on the back surface 12a side of the front panel section 12 of the lid section 11, and simplification of the mechanism and miniaturization by reducing the arrangement space can be achieved. it can.

尚、上記には、外筐２のトレイ挿脱孔７の開口縁の全周のみにリブ８を設けた例を示したが、例えば、図９に示すように、配置凹部６の底面部６ａに大きさの異なる複数の枠状のリブ８、８、・・・を設けることも可能である。このように複数のリブ８、８、・・・を設けることによりトレイ９と外筐２との間の密閉性が向上し得ると共に外筐２の内部から外部への音漏れ防止効果の向上を期待することができる。 In the above, the example in which the rib 8 is provided only on the entire circumference of the opening edge of the tray insertion / removal hole 7 of the outer casing 2 is shown. However, for example, as shown in FIG. It is also possible to provide a plurality of frame-like ribs 8, 8,. By providing a plurality of ribs 8, 8,..., The sealing between the tray 9 and the outer casing 2 can be improved, and the effect of preventing sound leakage from the inside of the outer casing 2 to the outside can be improved. You can expect.

電子機器１にあっては、トレイ９に弾性部材１４を取り付け外筐２にリブ８を設けているが、逆に、図１０に示すように、トレイ９にリブ１５を設け外筐２に弾性部材１６を取り付けてトレイ９と外筐２との間の密閉性を確保することも可能である。 In the electronic apparatus 1, the elastic member 14 is attached to the tray 9 and the rib 8 is provided to the outer casing 2. Conversely, as shown in FIG. 10, the rib 9 is provided to the tray 9 and elastic to the outer casing 2. It is also possible to secure the sealing property between the tray 9 and the outer casing 2 by attaching the member 16.

しかしながら、弾性部材１６を外筐２に取り付けた場合には、トレイ９の引出位置と引込位置との間の移動時における記録媒体装填部１０と弾性部材１６の接触を防止するために、図１０に示すように、弾性部材１６を内面がトレイ挿脱孔７の内周縁に一致した位置又はこれより外側に取り付ける必要がある。従って、引込位置において弾性部材１６の幅方向における中央部がリブ８に押し付けられるようにするためには、リブ１５をトレイ挿脱孔７より外側に位置させる必要が生じ、その分、蓋部１１の外形状が大きくなると言う問題が発生する。また、図１０に示すように、蓋部１１の外周部にリブ１５を設けた場合には、前方から見た状態で蓋部１１の外周側に弾性部材１６がはみ出してしまい視認性が低下し、このはみ出した部分を蓋部１１によって覆うようにすると、さらに蓋部１１の外形状を大きくする必要が生じてしまう。このような蓋部１１の大型化は、大きな配置凹部６を形成する必要上、電子機器１の大型化を来たすことになり、また、弾性部材が大きくなることで製造コストが上昇する。 However, when the elastic member 16 is attached to the outer casing 2, in order to prevent the recording medium loading unit 10 and the elastic member 16 from contacting each other when the tray 9 moves between the drawing position and the drawing position, FIG. As shown in FIG. 3, the elastic member 16 needs to be attached at a position where the inner surface coincides with the inner peripheral edge of the tray insertion / removal hole 7 or outside the tray. Accordingly, in order for the central portion in the width direction of the elastic member 16 to be pressed against the rib 8 at the retracted position, the rib 15 needs to be positioned outside the tray insertion / removal hole 7, and accordingly, the lid portion 11. There arises a problem that the outer shape of the is increased. Further, as shown in FIG. 10, when the rib 15 is provided on the outer peripheral portion of the lid portion 11, the elastic member 16 protrudes from the outer peripheral side of the lid portion 11 when viewed from the front, and the visibility is lowered. If the protruding part is covered with the lid part 11, it is necessary to further increase the outer shape of the lid part 11. Such an increase in the size of the lid 11 results in an increase in the size of the electronic device 1 due to the necessity of forming the large arrangement recess 6, and the manufacturing cost increases due to an increase in the elastic member.

そこで、電子機器１のように、トレイ９に弾性部材１４を取り付け外筐２にリブ８を設けることにより、上記した蓋部１１の大型化に起因する各種の不具合を生じることがなく、電子機器１の小型化及び製造コストの低減を図ることができる。 Therefore, unlike the electronic device 1, the elastic member 14 is attached to the tray 9 and the rib 8 is provided on the outer casing 2, so that various problems due to the increase in the size of the lid portion 11 do not occur. 1 can be reduced in size and manufacturing cost.

また、電子機器１にあっては、リブ８、８Ａ、８Ｂ、８Ｃを弾性部材１４に近付くに従って先細りとなる形状に形成しているため、弾性部材１４が小さな引込力で確実にリブ８、８Ａ、８Ｂ、８Ｃによって圧縮されてトレイ９と外筐２との間の良好な密閉性が確保され、また、引込力が小さくて済むためトレイ９を搬送するための搬送用モーターのトルクを小さくすることができる。 Further, in the electronic device 1, the ribs 8, 8A, 8B, and 8C are formed in a shape that tapers as they approach the elastic member 14, so that the elastic member 14 can be reliably secured with a small pulling force. , 8B, 8C to ensure a good sealing property between the tray 9 and the outer casing 2, and to reduce the torque of the transport motor for transporting the tray 9 because the pull-in force is small. be able to.

さらに、トレイ９が引込位置に移動されたときの弾性部材１４の圧縮量を厚みに対する５％乃至３０％にしているため、小さな引込力によってトレイ９を引込位置まで移動させることができる。 Furthermore, since the compression amount of the elastic member 14 when the tray 9 is moved to the retracted position is 5% to 30% of the thickness, the tray 9 can be moved to the retracted position with a small retracting force.

加えて、トレイ９が引込位置に移動された状態において、配置凹部６の底面部６ａと弾性部材１４の後面１４ａとの間に隙間が形成されるようにしているため、小さな引込力によってトレイ９と外筐２との間の安定した密閉状態を確保することができる。 In addition, since the gap is formed between the bottom surface portion 6a of the arrangement recess 6 and the rear surface 14a of the elastic member 14 in a state where the tray 9 is moved to the retracted position, the tray 9 can be operated with a small retracting force. And a stable sealed state between the outer casing 2 and the outer casing 2 can be ensured.
