Description
本発明は、回転操作可能な操作部材及びこれを有する電子機器に関し、特に電子機器に装備された操作部材の回転を検出する技術に関する。 The present invention relates to an operating member capable of rotation operation and an electronic device having the same, and more particularly to a technique for detecting the rotation of an operating member mounted on the electronic device.
電子機器には、様々な処理や動作を実行させるために、押しボタン式やスライド式、回転式等の種々の操作部材が実装されている。このような操作部材が操作されたときの操作部材の動作を検出する手段として、各種のセンサが用いられている。例えば、回転式の操作部材の一例である回転操作環の回転を、フォトリフレクタを用いて検知する技術が提案されている(特許文献1参照)。 Various operation members such as a push button type, a slide type, and a rotary type are mounted on the electronic device in order to execute various processes and operations. Various sensors are used as means for detecting the operation of the operating member when such an operating member is operated. For example, a technique for detecting the rotation of a rotary operating ring, which is an example of a rotary operating member, using a photoreflector has been proposed (see Patent Document 1).
具体的には、回転操作環に反射率の異なる反射面を一定の回転角度毎に交互に設け、回転操作環が回転操作されたときにフォトリフレクタのオン/オフ(受光/非受光)が切り替わる構成とする。これにより、回転操作環の回転を検知することができる。ここで、回転操作環に反射率の異なる反射面を形成する方法としては、環状部材の内周面に反射面を直接形成する方法や、環状部材の内周面に反射シートを貼り付ける方法等がある。 Specifically, reflective surfaces having different reflectances are alternately provided on the rotation operation ring at regular rotation angles, and the photoreflector is switched on / off (light reception / non-light reception) when the rotation operation ring is rotated. It is configured. Thereby, the rotation of the rotation operation ring can be detected. Here, as a method of forming the reflective surfaces having different reflectances on the rotation operation ring, a method of directly forming the reflective surface on the inner peripheral surface of the annular member, a method of attaching a reflective sheet to the inner peripheral surface of the annular member, and the like. There is.
しかしながら、環状部材に反射率の異なる反射面を直接形成して回転操作環を製造する場合、製造(加工)コストが高くなるという問題がある。これに対して、反射シートを環状部材に貼り付けて回転操作環を製造する場合には、環状部材に反射面を直接形成する場合よりも、製造コストを抑えることができる。しかし、360度の回転が可能な回転操作環では、反射シートを環状部材の内周面の全周にわたって貼り付ける必要が生じる。このとき、反射シートの継ぎ目に微小な隙間が生じ、或いは、反射シートの継ぎ目に微小な重なりが生じてしまうと、反射率の変化が一様でなくなることで、回転角度を検知した際に誤検知が生じるおそれがある。 However, when a rotary operation ring is manufactured by directly forming reflective surfaces having different reflectances on the annular member, there is a problem that the manufacturing (processing) cost becomes high. On the other hand, when the reflective sheet is attached to the annular member to manufacture the rotation operation ring, the manufacturing cost can be suppressed as compared with the case where the reflective surface is directly formed on the annular member. However, in the rotation operation ring capable of rotating 360 degrees, it is necessary to attach the reflective sheet over the entire inner peripheral surface of the annular member. At this time, if a minute gap is generated at the seam of the reflective sheet or a minute overlap is generated at the seam of the reflective sheet, the change in reflectance becomes not uniform, and an error is made when the rotation angle is detected. Detection may occur.
本発明は、製造コストが抑えられ、回転角度の誤検知を防止することができる回転操作可能な操作部材を提供することを目的とする。 An object of the present invention is to provide a rotation-operable operating member capable of suppressing manufacturing costs and preventing erroneous detection of a rotation angle.
本発明に係る操作部材は、円周面を有する環状部材と、前記円周面に固定されたシートと、を備え、前記シートの表面の反射率は前記円周面の反射率と異なり、前記シートは、前記円周面の周方向に並ぶ複数の孔部を有し、前記孔部から前記円周面の一部が露出し、かつ、前記シートの両端が前記周方向において互いに向かい合うように、前記円周面に固定され、前記周方向において前記シートの両端の間には、前記孔部の前記周方向の幅と略等しい幅を有する隙間が設けられ、前記隙間では前記円周面が露出していることを特徴とする。 Operating member according to the present invention comprises an annular member having a circular peripheral surface, and a sheet secured to the circumferential surface, the reflectance of the surface of the sheet is different from the reflectance before Symbol circumferential surface, The sheet has a plurality of holes arranged in the circumferential direction of the circumferential surface so that a part of the circumferential surface is exposed from the holes and both ends of the sheet face each other in the circumferential direction. Is fixed to the circumferential surface, and a gap having a width substantially equal to the width of the hole in the circumferential direction is provided between both ends of the sheet in the circumferential direction, and the circumferential surface is provided in the gap. Is exposed .
本発明によれば、回転操作可能な操作部材の製造コストを抑えることができる。また、操作部材の回転角度を検知する際に誤検知が発生することを防止することができる。 According to the present invention, it is possible to reduce the manufacturing cost of an operating member that can be rotated. In addition, it is possible to prevent erroneous detection from occurring when detecting the rotation angle of the operating member.
以下、本発明の実施形態について、添付図面を参照して詳細に説明する。本実施形態では、本発明に係る電子機器の一例として撮像装置を取り上げることとする。 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the present embodiment, an imaging device will be taken up as an example of the electronic device according to the present invention.
図1は、本発明の実施形態に係る撮像装置1の外観斜視図である。撮像装置1は、本発明に係る電子機器の一例である。撮像装置1は、大略的に、本体部1a及び円筒部1bから構成されている。本体部1aは、不図示であるが、撮像素子、画像処理回路、信号処理回路及びメモリカード等を有する。撮像素子は、被写体の光学像を光電変換する。画像処理回路は、撮像素子から出力されるアナログ信号をデジタル画像信号へ変換して所定の画像処理を施し、画像データを生成する。信号処理回路は、円筒部1bに設けられた後述のフォトリフレクタ10a,10b(図4参照)からの信号に基づき、後述の回転操作環4の回転を検知する。メモリカードは、画像処理回路から出力される画像データを記憶する。 FIG. 1 is an external perspective view of the image pickup apparatus 1 according to the embodiment of the present invention. The image pickup apparatus 1 is an example of an electronic device according to the present invention. The image pickup apparatus 1 is roughly composed of a main body portion 1a and a cylindrical portion 1b. Although not shown, the main body 1a includes an image sensor, an image processing circuit, a signal processing circuit, a memory card, and the like. The image sensor photoelectrically converts the optical image of the subject. The image processing circuit converts an analog signal output from an image pickup element into a digital image signal, performs predetermined image processing, and generates image data. The signal processing circuit detects the rotation of the rotation operation ring 4 described later based on the signals from the photo reflectors 10a and 10b (see FIG. 4) provided in the cylindrical portion 1b. The memory card stores image data output from the image processing circuit.
円筒部1bは、本体部1aの正面側中央付近に配置されている。円筒部1bは、撮像レンズ2及び鏡筒3を有する。撮像レンズ2は、撮像素子に結像する被写体像を形成する。鏡筒3は、撮像素子へ到達する光量を調整する不図示のシャッタ装置や絞り装置を備える。 The cylindrical portion 1b is arranged near the center on the front side of the main body portion 1a. The cylindrical portion 1b has an image pickup lens 2 and a lens barrel 3. The image pickup lens 2 forms a subject image to be imaged on the image pickup element. The lens barrel 3 includes a shutter device and an aperture device (not shown) that adjust the amount of light reaching the image sensor.
円筒部1bの外周には、本発明の第1実施形態に係る回転操作環4、円筒外装5及びキャップ6が設けられている。回転操作環4は、撮像素子の感度調整やシャッタ速度等の各種の撮像パラメータを変更する際に操作される回転操作可能な操作部材である。撮像装置1では、不図示の設定手段によって、回転操作環4の操作によって設定値の変更が可能な撮像パラメータを予め設定することができるようになっている。よって、回転操作環4を回転操作することによって、予め設定した所望の撮像パラメータの設定値を変更することができる。なお、キャップ6及び円筒外装5については、図2を参照して後に説明する。また、撮像装置1のその他の構成部品については、本発明と直接の関係がないため、説明を省略する。 A rotation operation ring 4, a cylindrical exterior 5, and a cap 6 according to the first embodiment of the present invention are provided on the outer periphery of the cylindrical portion 1b. The rotation operation ring 4 is an operation member capable of rotation operation that is operated when various image pickup parameters such as sensitivity adjustment of the image pickup element and shutter speed are changed. In the image pickup apparatus 1, an image pickup parameter whose set value can be changed by operating the rotation operation ring 4 can be set in advance by a setting means (not shown). Therefore, by rotating the rotation operation ring 4, it is possible to change the preset values of the desired imaging parameters. The cap 6 and the cylindrical exterior 5 will be described later with reference to FIG. Further, since the other components of the image pickup apparatus 1 are not directly related to the present invention, description thereof will be omitted.
図2(a)は、円筒部1bの概略構造を示す断面図である。また、図2(b)は、図2(a)に示す領域Sの部分拡大図である。図2(a),(b)では、鏡筒3の内部に配置される撮像レンズ2等の部品については、本発明と直接の関係がないため、図示を省略している。 FIG. 2A is a cross-sectional view showing a schematic structure of the cylindrical portion 1b. Further, FIG. 2B is a partially enlarged view of the region S shown in FIG. 2A. In FIGS. 2A and 2B, parts such as the image pickup lens 2 arranged inside the lens barrel 3 are not shown because they are not directly related to the present invention.
円筒部1bは、鏡筒3の外周に配置されたベース部材8を有する。ベース部材8の先端側(被写体側)には、キャップ6が配置されている。ベース部材8の外周には、回転操作環4及び円筒外装5が配置されている。円筒外装5とベース部材8は、不図示の部品を介して本体部1aへ固定される。キャップ6は、円筒外装5とで回転操作環4を挟み込むようにして、不図示のビスによって、ベース部材8を介して本体部1aに固定される。回転操作環4は、鏡筒3の光軸L方向において円筒外装5とキャップ6とで挟持されているため、回転操作環4の光軸L方向への移動は、一定のガタを除いて規制されている。しかし、回転操作環4は、光軸Lを中心軸とした回転方向では動きに規制はなく、360度の回転が可能となっている。 The cylindrical portion 1b has a base member 8 arranged on the outer periphery of the lens barrel 3. A cap 6 is arranged on the tip end side (subject side) of the base member 8. A rotation operation ring 4 and a cylindrical exterior 5 are arranged on the outer periphery of the base member 8. The cylindrical exterior 5 and the base member 8 are fixed to the main body 1a via a component (not shown). The cap 6 is fixed to the main body 1a via the base member 8 by a screw (not shown) so as to sandwich the rotation operation ring 4 with the cylindrical exterior 5. Since the rotation operation ring 4 is sandwiched between the cylindrical exterior 5 and the cap 6 in the optical axis L direction of the lens barrel 3, the movement of the rotation operation ring 4 in the optical axis L direction is restricted except for a certain amount of play. Has been done. However, the rotation operation ring 4 has no restriction on its movement in the rotation direction about the optical axis L as a central axis, and can rotate 360 degrees.
キャップ6には、溝6aが設けられている。溝6aの内部には、樹脂材の一例であるゴム材からなるリング部材7が嵌め込まれている。リング部材7の内径は単体の状態では溝6aの外径より小さく、そのため、リング部材7は伸び広げられながら溝6aへ嵌め込まれる。回転操作環4が光軸L方向において円筒外装5とキャップ6とによって挟持された状態では、リング部材7は、回転操作環4に設けられた突出部4eによって、光軸Lと直交する方向(ラジアル方向)に付勢(加圧)され、圧縮される。突出部4eは、円筒部1bでは、回転操作環4の内周の3カ所に周方向に略等間隔で設けられており、これにより、リング部材7はバランスよく突出部4eによって付勢される。突出部4eによるリング部材7への付勢により、回転操作環4を回転操作する際に一定の操作負荷が加わることで、回転操作環4が不用意に回転してしまうことを防止して、操作性を向上させることができる。なお、突出部4eは、4カ所以上に設けられていてもよい。 The cap 6 is provided with a groove 6a. A ring member 7 made of a rubber material, which is an example of a resin material, is fitted inside the groove 6a. The inner diameter of the ring member 7 is smaller than the outer diameter of the groove 6a in a single state, so that the ring member 7 is fitted into the groove 6a while being stretched and expanded. In a state where the rotation operation ring 4 is sandwiched between the cylindrical exterior 5 and the cap 6 in the direction of the optical axis L, the ring member 7 is in a direction orthogonal to the optical axis L by the protrusion 4e provided on the rotation operation ring 4. It is urged (pressurized) in the radial direction) and compressed. In the cylindrical portion 1b, the projecting portions 4e are provided at three positions on the inner circumference of the rotation operation ring 4 at substantially equal intervals in the circumferential direction, whereby the ring member 7 is urged by the projecting portions 4e in a well-balanced manner. .. By urging the ring member 7 by the protrusion 4e, a constant operation load is applied when the rotation operation ring 4 is rotated, so that the rotation operation ring 4 is prevented from being inadvertently rotated. Operability can be improved. The protruding portions 4e may be provided at four or more locations.
図3(a)は、回転操作環4の斜視図である。図3(b)は、回転操作環4の内周面(円周面)の平面展開図である。回転操作環4は、環状部材12と、環状部材12の内周面に貼り付けられたシート11とを有する。 FIG. 3A is a perspective view of the rotation operation ring 4. FIG. 3B is a plan development view of the inner peripheral surface (circumferential surface) of the rotation operation ring 4. The rotation operation ring 4 has an annular member 12 and a sheet 11 attached to the inner peripheral surface of the annular member 12.
環状部材12は、例えば、アルミ材の切削加工によって製造されており、外周は凹凸状に形成され、その表面はブラスト処理によって粗い表面に仕上げられている。これにより、回転操作環4の外周面を把持して回転操作する際の指の滑りを抑制して、操作性を高めることができる。環状部材12の内周面において少なくともシート11が貼り付けられる領域は、反射率の高い面の一例である光沢面12aに仕上げられている。 The annular member 12 is manufactured, for example, by cutting an aluminum material, has an outer peripheral surface formed in an uneven shape, and has a rough surface finished by a blasting process. As a result, it is possible to suppress the slippage of the finger when gripping and rotating the outer peripheral surface of the rotation operation ring 4, and improve the operability. At least the region on the inner peripheral surface of the annular member 12 to which the sheet 11 is attached is finished with a glossy surface 12a, which is an example of a surface having high reflectance.
環状部材12の内周面には、シート11が、その両端が環状部材12の周方向において互いに向かい合うように貼り付けられている。シート11の表面は、反射率の低い面の一例である非光沢面11aとなっている。 A sheet 11 is attached to the inner peripheral surface of the annular member 12 so that both ends thereof face each other in the circumferential direction of the annular member 12. The surface of the sheet 11 is a non-glossy surface 11a, which is an example of a surface having a low reflectance.
なお、図3(b)では、非光沢面11aと光沢面12aとを区別するために、便宜的に、非光沢面11aに斜線を施している。また、後に説明する図6(a),(b),(c)及び図7(a),(b)でも、同様の理由で、非光沢面に斜線を施している。 In FIG. 3B, the non-glossy surface 11a is shaded for convenience in order to distinguish the non-glossy surface 11a from the glossy surface 12a. Further, in FIGS. 6 (a), (b), (c) and 7 (a), (b), which will be described later, the non-glossy surface is shaded for the same reason.
シート11の材質は限定されるものではない。シート11には、環状部材12の周方向に対応する長さ方向に、所定の幅Aの複数の孔部11bが、幅Aの間隔で並んで形成されている。つまり、シート11において隣接する孔部11b間での非光沢面11aの幅もまた幅Aである。また、シート11の長さは、シート11が環状部材12に貼り付けられた状態で、環状部材12の周方向で対向する両端間に所定の幅Bの隙間12bが形成されるように、予め設定されている。隙間12bの幅Bは、孔部11bの幅Aと略同じ幅に設定される。 The material of the sheet 11 is not limited. In the sheet 11, a plurality of holes 11b having a predetermined width A are formed side by side at intervals of the width A in the length direction corresponding to the circumferential direction of the annular member 12. That is, the width of the non-glossy surface 11a between the adjacent holes 11b in the sheet 11 is also the width A. Further, the length of the sheet 11 is set in advance so that a gap 12b having a predetermined width B is formed between both ends of the annular member 12 facing each other in the circumferential direction in a state where the sheet 11 is attached to the annular member 12. It is set. The width B of the gap 12b is set to substantially the same width as the width A of the hole portion 11b.
なお、光沢面であるか非光沢面であるかの判断は、見た者の主観に依存するところが大きいが、本実施形態では、光沢面と非光沢面とを、反射率の異なる面の典型的な組み合わせとして用いている。後述するように、本実施形態では、光学式センサの一例であるフォトリフレクタの発光部から回転操作環4の内周面へ向けて投光する。そして、回転操作環4の内周面からの反射光をフォトリフレクタの受光部が受光したか否かを示す信号に基づいて、回転操作環4の回転が検知される。そこで、フォトリフレクタの受光部が受光可能な反射光を生じさせる面の一例として光沢面を用い、フォトリフレクタの受光部が受光不可能な反射光を生じさせる面の一例として非光沢面を用いている。したがって、環状部材12の内周面とシート11の表面は、見かけに関係なく、反射光の受光と非受光とがフォトリフレクタによって識別可能な程度の反射率の差を有していればよい。 The determination of whether the surface is glossy or non-glossy largely depends on the subjectivity of the viewer, but in the present embodiment, the glossy surface and the non-glossy surface are typical of surfaces having different reflectances. It is used as a typical combination. As will be described later, in the present embodiment, light is projected from the light emitting portion of the photoreflector, which is an example of the optical sensor, toward the inner peripheral surface of the rotation operation ring 4. Then, the rotation of the rotation operation ring 4 is detected based on the signal indicating whether or not the light receiving portion of the photoreflector has received the reflected light from the inner peripheral surface of the rotation operation ring 4. Therefore, a glossy surface is used as an example of a surface on which the light receiving portion of the photoreflector generates reflected light that can be received, and a non-glossy surface is used as an example of a surface on which the light receiving portion of the photoreflector generates reflected light that cannot be received. There is. Therefore, the inner peripheral surface of the annular member 12 and the surface of the sheet 11 need to have a difference in reflectance to such an extent that the light receiving and the non-light receiving of the reflected light can be distinguished by the photoreflector regardless of the appearance.
回転操作環4の内周面では、孔部11bと隙間12bの各領域で、環状部材12の内周面である光沢面12aが露出している。したがって、回転操作環4の内周面には、孔部11bと隙間12bの各領域で露出している光沢面12aと、シート11における孔部11bと孔部11bとの間の領域の非光沢面11aとが、全周に亘って交互に設けられる。本実施形態では、孔部11b及び隙間12bの各領域の幅が角度4度分の幅に設定され、且つ、孔部11bと孔部11bとの間の幅Aの領域も角度4度分の幅に設定されている。よって、光沢面12aと非光沢面11aとが8度ピッチで4度ずつ交互に配置されている。 On the inner peripheral surface of the rotation operation ring 4, the glossy surface 12a, which is the inner peripheral surface of the annular member 12, is exposed in each region of the hole portion 11b and the gap 12b. Therefore, on the inner peripheral surface of the rotation operation ring 4, the glossy surface 12a exposed in each region of the hole 11b and the gap 12b and the non-glossy region between the hole 11b and the hole 11b in the sheet 11 The surfaces 11a are alternately provided over the entire circumference. In the present embodiment, the width of each region of the hole 11b and the gap 12b is set to a width of 4 degrees, and the region of the width A between the hole 11b and the hole 11b is also set to an angle of 4 degrees. It is set to the width. Therefore, the glossy surface 12a and the non-glossy surface 11a are alternately arranged at a pitch of 8 degrees by 4 degrees.
ここで、環状部材の内周面にシートを貼り付けた場合に、シートの両端間に隙間を設けずに端面同士を合わせた場合には、シートの両端間に微小な隙間が生じ、或いは、微小な重なりが生じてしまうことがある。これに対して、環状部材12の内周面にシート11が貼り付けられたときに、シート11の両端間に幅Bの隙間12bを意図的に設けることにより、シート11の両端間に微小な隙間や重なりが生じることを回避することができる。これにより、後述するように、回転操作環4の回転を検知する際に誤検知が生じることを防止することができる。 Here, when the sheet is attached to the inner peripheral surface of the annular member, if the end faces are aligned without providing a gap between both ends of the sheet, a minute gap is generated between both ends of the sheet, or A small amount of overlap may occur. On the other hand, when the sheet 11 is attached to the inner peripheral surface of the annular member 12, a gap 12b having a width B is intentionally provided between both ends of the sheet 11, so that a minute gap 12b is provided between both ends of the sheet 11. It is possible to avoid the occurrence of gaps and overlaps. As a result, as will be described later, it is possible to prevent erroneous detection from occurring when detecting the rotation of the rotation operation ring 4.
図3(a),(b)にはそれぞれ、回転操作環4の回転を検出するための2つのフォトリフレクタ10a,10bが図示されており、図3(a)には、2つのフォトリフレクタ10a,10bが実装されたフレキシブル配線基板9が図示されている。 3 (a) and 3 (b) show two photo reflectors 10a and 10b for detecting the rotation of the rotation operation ring 4, respectively, and FIG. 3 (a) shows two photo reflectors 10a. , 10b is mounted on the flexible wiring board 9.
フォトリフレクタ10a,10bの発光部と受光部は、回転操作環4の内周側に、外周側を向いて配置されている。フォトリフレクタ10a,10bで回転操作環4の回転を検知するためには、フォトリフレクタ10a,10bと対面した回転操作環4の内周面に、反射率の異なる面を、少なくとも交互に設ける必要がある。ここで、前述の通り、環状部材12の内周面は光沢面12aに仕上げられている。そこで、フォトリフレクタ10a,10bの発光部から光沢面12aへ投光されて光沢面12aで反射した光をフォトリフレクタ10a,10bの受光部で検知することができるように、環状部材12の内周面とフォトリフレクタ10a,10bとの間の距離を定める。このとき、シート11の表面の非光沢面11aは、フォトリフレクタ10a,10bの発光部から非光沢面11aへ投光されて非光沢面11aで反射した光をフォトリフレクタ10a,10bの受光部で検知不可能な反射率に設定される。これにより、回転操作環4の回転に伴って、フォトリフレクタ10a,10bの受光部に受光状態と非受光状態を交互に生じさせて、撮像装置1が備える不図示の信号処理回路へ受光状態と非受光状態とを示す信号を送ることが可能になる。 The light emitting portion and the light receiving portion of the photoreflectors 10a and 10b are arranged on the inner peripheral side of the rotation operation ring 4 so as to face the outer peripheral side. In order for the photoreflectors 10a and 10b to detect the rotation of the rotation operation ring 4, it is necessary to provide at least alternately surfaces having different reflectances on the inner peripheral surface of the rotation operation ring 4 facing the photoreflectors 10a and 10b. is there. Here, as described above, the inner peripheral surface of the annular member 12 is finished with a glossy surface 12a. Therefore, the inner circumference of the annular member 12 can be detected by the light receiving portion of the photoreflectors 10a and 10b so that the light projected from the light emitting portion of the photoreflectors 10a and 10b to the glossy surface 12a and reflected by the glossy surface 12a can be detected. The distance between the surface and the photo reflectors 10a and 10b is determined. At this time, the non-glossy surface 11a on the surface of the sheet 11 is projected from the light emitting portion of the photoreflectors 10a and 10b to the non-glossy surface 11a and reflected by the non-glossy surface 11a by the light receiving portion of the photoreflectors 10a and 10b. The reflectance is set to be undetectable. As a result, as the rotation operation ring 4 rotates, the light receiving states of the photoreflectors 10a and 10b are alternately generated in the light receiving state and the non-light receiving state, and the signal processing circuit (not shown) provided in the image pickup apparatus 1 is subjected to the light receiving state. It becomes possible to send a signal indicating a non-light receiving state.
次に、回転操作環4が回転操作された際の回転角度の検出方法について説明する。図4は、円筒部1bの分解斜視図であり、回転操作環4及びその周囲の部材を示している。ベース部材8には、フレキシブル配線基板9が固定されており、フレキシブル配線基板9に2つのフォトリフレクタ10a,10bが実装されている。フォトリフレクタ10a,10bの配設ピッチは、図3(b)に示すように、一方が光沢面12a(孔部11b又は隙間12bの領域)のほぼ中心と対向する位置にあるときに、他方が光沢面12aと非光沢面11aとの境界と対向する位置にあるように設定される。これにより、2つのフォトリフレクタ10a,10bから出力される信号波形の位相差を最大とすることができる。 Next, a method of detecting the rotation angle when the rotation operation ring 4 is rotated will be described. FIG. 4 is an exploded perspective view of the cylindrical portion 1b, showing the rotation operation ring 4 and its surrounding members. A flexible wiring board 9 is fixed to the base member 8, and two photoreflectors 10a and 10b are mounted on the flexible wiring board 9. As shown in FIG. 3B, the arrangement pitch of the photoreflectors 10a and 10b is such that when one is positioned so as to face substantially the center of the glossy surface 12a (the region of the hole 11b or the gap 12b), the other is It is set so as to face the boundary between the glossy surface 12a and the non-glossy surface 11a. Thereby, the phase difference of the signal waveforms output from the two photo reflectors 10a and 10b can be maximized.
回転操作環4の回転方向を検出するためには、フォトリフレクタ10a,10bから出力される信号波形に位相差が生じていることが必要である。つまり、フォトリフレクタ10aが受光したときに、回転操作環4の回転方向によってフォトリフレクタ10bが受光しているか否かの差異が生じることが必要となる。この差異に基づいて、回転操作環4がどの方向に回転しているかを信号処理回路によって判別することができる。 In order to detect the rotation direction of the rotation operation ring 4, it is necessary that the signal waveforms output from the photoreflectors 10a and 10b have a phase difference. That is, when the photoreflector 10a receives light, it is necessary that there is a difference in whether or not the photoreflector 10b receives light depending on the rotation direction of the rotation operation ring 4. Based on this difference, the signal processing circuit can determine in which direction the rotation operation ring 4 is rotating.
図5(a)は、撮像装置1の背面側から見て時計回り(CW)方向(図4参照)に回転操作環4が回転操作された際にフォトリフレクタ10a,10bから出力される信号波形である。図5(b)は、時計回りの方向の逆方向である反時計回り(CCW)方向(図4参照)に回転操作環4が回転操作された際にフォトリフレクタ10a,10bから出力される信号波形である。なお、図5(a),(b)では、フォトリフレクタ10aをPR10aと記し、フォトリフレクタ10bをPR10bと記している。また、信号波形がHighを示す範囲は、フォトリフレクタ10a,10bがそれぞれ受光状態にあることを示し、信号波形がLowで示す範囲は、フォトリフレクタ10a,10bがそれぞれ非受光状態にあることを示している。 FIG. 5A shows signal waveforms output from the photoreflectors 10a and 10b when the rotation operation ring 4 is rotated in the clockwise (CW) direction (see FIG. 4) when viewed from the back side of the image pickup apparatus 1. Is. FIG. 5B shows signals output from the photoreflectors 10a and 10b when the rotation operation ring 4 is rotated in the counterclockwise (CCW) direction (see FIG. 4), which is the opposite direction of the clockwise direction. It is a waveform. In FIGS. 5A and 5B, the photoreflector 10a is referred to as PR10a, and the photoreflector 10b is referred to as PR10b. Further, the range in which the signal waveform indicates High indicates that the photoreflectors 10a and 10b are in the light receiving state, respectively, and the range in which the signal waveform indicates Low indicates that the photoreflectors 10a and 10b are in the non-light receiving state, respectively. ing.
フォトリフレクタ10a,10bの信号波形に位相差がない場合には、回転操作環4をどの方向に回転させても、フォトリフレクタ10a,10bの信号波形が同じとなるため、回転方向を検知することはできない。一方、フォトリフレクタ10a,10bの信号波形の位相差が小さい場合には、位相差の有無の判定にばらつきが生じ、回転方向を誤検知するおそれがある。 When there is no phase difference in the signal waveforms of the photoreflectors 10a and 10b, the signal waveforms of the photoreflectors 10a and 10b are the same regardless of the direction in which the rotation operation ring 4 is rotated, so that the rotation direction is detected. Can't. On the other hand, when the phase difference between the signal waveforms of the photo reflectors 10a and 10b is small, the determination of the presence or absence of the phase difference may vary, and the rotation direction may be erroneously detected.
そこで、円筒部1bでは、フォトリフレクタ10a,10bから出力される信号波形に、概ね、半位相分の位相差を生じさせている。回転操作環4が時計回りに回転操作された場合、フォトリフレクタ10aの受光部の受光状態が(1)High、(2)High、(3)Low、(4)Lowと変化する際に、フォトリフレクタ10bの受光状態は(1)High、(2)Low、(3)Low、(4)Highと変化する。回転操作環4が反時計回りに回転操作された場合、フォトリフレクタ10aの受光部の受光状態が(1)High、(2)High、(3)Low、(4)Lowと変化する際に、フォトリフレクタ10bの受光状態は(1)Low、(2)High、(3)High、(4)Lowと変化する。このような順序が守られている場合には、上記(1)から(4)のいずれのタイミングから回転が開始されても、回転操作環4の回転方向を検知することができる。そして、回転操作環4の回転角度を、回転方向と回転開始位置によらず、フォトリフレクタ10a,10bが上記(1)から(4)まで順番に変化することで1ピッチ(1周期)分だけ回転したことを、本体部1aに設けられた不図示の信号処理回路によって判別する。 Therefore, in the cylindrical portion 1b, a phase difference of approximately half a phase is generated in the signal waveforms output from the photoreflectors 10a and 10b. When the rotation operation ring 4 is rotated clockwise, the photo is taken when the light receiving state of the light receiving portion of the photo reflector 10a changes to (1) High, (2) High, (3) Low, and (4) Low. The light receiving state of the reflector 10b changes as (1) High, (2) Low, (3) Low, and (4) High. When the rotation operation ring 4 is rotated counterclockwise, when the light receiving state of the light receiving portion of the photo reflector 10a changes to (1) High, (2) High, (3) Low, and (4) Low. The light receiving state of the photo reflector 10b changes as (1) Low, (2) High, (3) High, and (4) Low. When such an order is observed, the rotation direction of the rotation operation ring 4 can be detected regardless of the timing of the above (1) to (4). Then, the rotation angle of the rotation operation ring 4 is changed in order from (1) to (4) above by the photoreflectors 10a and 10b regardless of the rotation direction and the rotation start position, so that only one pitch (one cycle) is required. The rotation is determined by a signal processing circuit (not shown) provided in the main body 1a.
前述の通り、回転操作環4の内周面においてフォトリフレクタ10a,10bと対面する位置には、孔部11b及び隙間12bにおいて露出した光沢面12aとシート11の非光沢面11aとが約4度ずつで交互に、周方向の全周にわたって設けられている。よって、回転操作環4の内周面には、合計で45カ所の光沢面12aが存在する。したがって、回転操作環4を8度回転させる毎に回転操作環4の回転を検出することができる。図5(a),(b)において、フォトリフレクタ10aでの信号の隣接する立ち上がり位置α間の間隔が、回転操作環4の8度の回転に相当する。 As described above, the glossy surface 12a exposed in the holes 11b and the gap 12b and the non-glossy surface 11a of the sheet 11 are about 4 degrees at the positions facing the photoreflectors 10a and 10b on the inner peripheral surface of the rotation operation ring 4. It is provided alternately over the entire circumference in the circumferential direction. Therefore, there are a total of 45 glossy surfaces 12a on the inner peripheral surface of the rotation operation ring 4. Therefore, the rotation of the rotation operation ring 4 can be detected every time the rotation operation ring 4 is rotated 8 degrees. In FIGS. 5A and 5B, the distance between adjacent rising positions α of the signal in the photoreflector 10a corresponds to the rotation of the rotation operation ring 4 by 8 degrees.
以上の説明の通り、回転操作環4は、環状部材12の内周面においてシート11が貼り付けられる領域全体が光沢面12aとなるように製造されている。そのため、環状部材12の内周面に異なる反射率の反射面を直接形成する場合よりも成形や加工が容易であり、製造コストを下げることが可能になる。また、表面が非光沢面11aとなっており、幅Aの孔部11bが幅Aの間隔で並べて形成されたシート11を、環状部材12の内周面に貼り付けている。こうして、周方向で対向するシート11の両端間に、幅Aと略等しい幅Bの隙間12bを形成して、光沢面12aを露出させている。これにより、回転操作環4が回転操作されたときの回転操作環4の回転角度及び回転方向を誤検知することなく、正確に検出することができ、ひいては、撮像装置1の信頼性を高めることができる。 As described above, the rotation operation ring 4 is manufactured so that the entire region to which the sheet 11 is attached on the inner peripheral surface of the annular member 12 becomes a glossy surface 12a. Therefore, molding and processing are easier than when reflective surfaces having different reflectances are directly formed on the inner peripheral surface of the annular member 12, and the manufacturing cost can be reduced. Further, a sheet 11 having a non-glossy surface 11a on the surface and having holes 11b having a width A arranged side by side at intervals of the width A is attached to the inner peripheral surface of the annular member 12. In this way, a gap 12b having a width B substantially equal to the width A is formed between both ends of the sheets 11 facing each other in the circumferential direction to expose the glossy surface 12a. As a result, the rotation angle and rotation direction of the rotation operation ring 4 when the rotation operation ring 4 is rotated can be accurately detected without being erroneously detected, and the reliability of the image pickup apparatus 1 can be improved. Can be done.
次に、本発明の第2実施形態に係る回転操作可能な操作部材について、図6(a)を参照して説明する。図6(a)は、本発明の第2実施形態に係る回転操作環24の内周面の平面展開図である。回転操作環24は、以下に説明する通り、上述した回転操作環4の内周面での光沢面と非光沢面の配置が逆となった構造を有する。 Next, the rotation-operable operating member according to the second embodiment of the present invention will be described with reference to FIG. 6A. FIG. 6A is a plan development view of the inner peripheral surface of the rotation operation ring 24 according to the second embodiment of the present invention. As described below, the rotation operation ring 24 has a structure in which the arrangement of the glossy surface and the non-glossy surface on the inner peripheral surface of the rotation operation ring 4 is reversed.
回転操作環24は、環状部材22と、環状部材22の内周面に貼り付けられたシート21とを有する。環状部材22は、内周面が非光沢面22aに形成されている点で、上述した環状部材12と異なるが、その他の構成は環状部材12と同じである。 The rotation operation ring 24 has an annular member 22 and a sheet 21 attached to the inner peripheral surface of the annular member 22. The annular member 22 is different from the above-mentioned annular member 12 in that the inner peripheral surface is formed on the non-glossy surface 22a, but other configurations are the same as those of the annular member 12.
シート21には、環状部材22の周方向に対応する長さ方向に、所定の幅Aの複数の孔部21bが幅Aの間隔で並んで形成されている。また、シート21の表面は光沢面21aとなっている。シート21が環状部材22に貼り付けられた状態で、環状部材22の周方向で対向する両端間には、幅Bの隙間22bが形成される。回転操作環24では、シート21に形成された幅Aの孔部21b及び周方向で対向する両端間に形成される幅Bの隙間22bの各領域で、環状部材22の非光沢面22aが露出している。なお、シート21は、幅Bが幅Aと略等しくなる長さに設定されている。また、回転操作環24の内周面に設けられる光沢面21aと非光沢面22aの定義は、上述した第1実施形態での定義と同じである。 In the sheet 21, a plurality of holes 21b having a predetermined width A are formed side by side at intervals of the width A in the length direction corresponding to the circumferential direction of the annular member 22. The surface of the sheet 21 is a glossy surface 21a. In a state where the sheet 21 is attached to the annular member 22, a gap 22b having a width B is formed between both ends of the annular member 22 facing each other in the circumferential direction. In the rotation operation ring 24, the non-glossy surface 22a of the annular member 22 is exposed in each region of the hole portion 21b of the width A formed in the sheet 21 and the gap 22b of the width B formed between both ends facing each other in the circumferential direction. doing. The sheet 21 is set to a length in which the width B is substantially equal to the width A. Further, the definitions of the glossy surface 21a and the non-glossy surface 22a provided on the inner peripheral surface of the rotation operation ring 24 are the same as the definitions in the first embodiment described above.
回転操作環24を円筒部1bに適用した場合に、シート21の光沢面21aは、フォトリフレクタ10a,10bの発光部から光沢面21aへ投光したときの光沢面21aからの反射光をフォトリフレクタ10a,10bの受光部で検知可能な反射率に調整されている。一方、環状部材22の非光沢面22aは、フォトリフレクタ10a,10bの発光部から非光沢面22aへ投光したときの非光沢面22aからの反射光をフォトリフレクタ10a,10bの受光部で検知不可能な反射率に調整されている。その結果、回転操作環24の内周面には、光沢面と非光沢面とが、実質的に幅Aで全周に亘って交互に設けられる。 When the rotation operation ring 24 is applied to the cylindrical portion 1b, the glossy surface 21a of the sheet 21 photoreflects the reflected light from the glossy surface 21a when the light emitting portion of the photoreflectors 10a and 10b is projected onto the glossy surface 21a. The reflectance is adjusted so that it can be detected by the light receiving portions of 10a and 10b. On the other hand, the non-glossy surface 22a of the annular member 22 detects the reflected light from the non-glossy surface 22a when the light is projected from the light emitting portion of the photoreflectors 10a and 10b to the non-glossy surface 22a by the light receiving portion of the photoreflectors 10a and 10b. Adjusted to an impossible reflectance. As a result, glossy surfaces and non-glossy surfaces are alternately provided on the inner peripheral surface of the rotation operation ring 24 over the entire circumference with substantially a width A.
したがって、回転操作環24が回転操作されたときにフォトリフレクタ10a,10bから得られる波形信号は、図5(a),(b)を参照して説明した波形信号の位相が半周期だけずれたものとなる。したがって、回転操作環24が回転操作されたときの回転角度及び回転方向は、第1実施形態に係る回転操作環4が回転操作されたときの回転量角度及び回転方向と同様に検知可能である。よって、回転操作環24でも、回転操作環4が奏する効果と同じ効果を得ることができる。 Therefore, the waveform signals obtained from the photoreflectors 10a and 10b when the rotation operation ring 24 is rotated are shifted in phase by half a cycle from the waveform signals described with reference to FIGS. 5A and 5B. It becomes a thing. Therefore, the rotation angle and the rotation direction when the rotation operation ring 24 is rotated can be detected in the same manner as the rotation amount angle and the rotation direction when the rotation operation ring 4 according to the first embodiment is rotated. .. Therefore, even with the rotation operation ring 24, the same effect as that of the rotation operation ring 4 can be obtained.
次に、本発明の第3実施形態に係る回転操作可能な操作部材について、図6(b)を参照して説明する。図6(b)は、本発明の第3実施形態に係る回転操作環34の内周面の平面展開図である。回転操作環34は、環状部材12と、環状部材12の内周面に貼り付けられたシート31とを有する。環状部材12は、第1実施形態で説明した環状部材12と同じであり、その内周面は光沢面12aとなっている。 Next, the rotation-operable operating member according to the third embodiment of the present invention will be described with reference to FIG. 6 (b). FIG. 6B is a plan development view of the inner peripheral surface of the rotation operation ring 34 according to the third embodiment of the present invention. The rotation operation ring 34 has an annular member 12 and a sheet 31 attached to the inner peripheral surface of the annular member 12. The annular member 12 is the same as the annular member 12 described in the first embodiment, and its inner peripheral surface is a glossy surface 12a.
シート31は、環状部材12の周方向に対応するシート31の長さ方向に、第1の反射領域である幅Aの非光沢面31bと第2の反射領域である幅Aの光沢面31aとが交互に並べられた構成となっている。シート31では、その長さ方向と直交する幅方向(図6(b)では上下方向)において、光沢面31aが非光沢面31bの一部に挟まれているが、幅方向端部側の非光沢面31bは必ずしも必要なものではない。 The sheet 31 has a non-glossy surface 31b having a width A which is a first reflection region and a glossy surface 31a having a width A which is a second reflection region in the length direction of the sheet 31 corresponding to the circumferential direction of the annular member 12. Are arranged alternately. In the sheet 31, the glossy surface 31a is sandwiched between a part of the non-glossy surface 31b in the width direction (vertical direction in FIG. 6B) orthogonal to the length direction, but the non-glossy surface 31a is on the end side in the width direction. The glossy surface 31b is not always necessary.
シート31としては、表面全体が非光沢面31bのシートに光沢面31aを印刷等によって形成したもの、又は、表面全体が光沢面31aのシートに非光沢面31bを印刷等によって形成したものを用いることができるが、これに限定されるものではない。 As the sheet 31, a sheet having a glossy surface 31a formed on a sheet having a non-glossy surface 31b on the entire surface by printing or the like, or a sheet having a non-glossy surface 31b formed on a sheet having a glossy surface 31a on the entire surface by printing or the like is used. It can, but is not limited to.
環状部材12の内周面にシート31が貼り付けられた状態で、環状部材12の周方向で対向するシート31の両端間には、幅Bの隙間12bが形成される。シート31は、幅Bが幅Aと略等しくなる長さに設定されている。 With the sheet 31 attached to the inner peripheral surface of the annular member 12, a gap 12b having a width B is formed between both ends of the sheet 31 facing the annular member 12 in the circumferential direction. The sheet 31 is set to a length in which the width B is substantially equal to the width A.
ここで、シート31の表面の光沢面31a及び非光沢面31bの各反射率と、環状部材12の内周面の光沢面12aの反射率との関係について説明する。フォトリフレクタ10a,10bが、光沢面31aからの反射光は受光するが、非光沢面31bからの反射光を受光することができないように、光沢面31aと非光沢面31bの各反射率には差が設けられている必要がある。また、光沢面12aが露出している隙間12bは、環状部材12の周方向において非光沢面31bに挟まれている必要がある。そして、フォトリフレクタ10a,10bが、光沢面12aからの反射光は受光するが、非光沢面31bからの反射光を受光することができないように、光沢面12aと非光沢面31bの各反射率にも差が設けられている必要がある。そこで、光沢面31a、非光沢面31b及び光沢面12aの反射率は、光沢面12aの反射率と光沢面31aの反射率との差が、非光沢面31bの反射率と光沢面31aの反射率との差よりも小さくなるように設定される。これにより、回転操作環34が回転操作されたときにフォトリフレクタ10a,10bから得られる波形信号を、図5(a),(b)を参照して説明した波形信号と同等なものとすることができる。 Here, the relationship between the reflectances of the glossy surface 31a and the non-glossy surface 31b on the surface of the sheet 31 and the reflectance of the glossy surface 12a on the inner peripheral surface of the annular member 12 will be described. The reflectances of the glossy surface 31a and the non-glossy surface 31b are set so that the photo reflectors 10a and 10b receive the reflected light from the glossy surface 31a but cannot receive the reflected light from the non-glossy surface 31b. There must be a difference. Further, the gap 12b where the glossy surface 12a is exposed needs to be sandwiched between the non-glossy surface 31b in the circumferential direction of the annular member 12. Then, the reflectances of the glossy surface 12a and the non-glossy surface 31b are obtained so that the photo reflectors 10a and 10b receive the reflected light from the glossy surface 12a but cannot receive the reflected light from the non-glossy surface 31b. Must also have a difference. Therefore, the reflectance of the glossy surface 31a, the non-glossy surface 31b, and the glossy surface 12a is such that the difference between the reflectance of the glossy surface 12a and the reflectance of the glossy surface 31a is the reflectance of the non-glossy surface 31b and the reflection of the glossy surface 31a. It is set to be smaller than the difference from the rate. As a result, the waveform signal obtained from the photoreflectors 10a and 10b when the rotation operation ring 34 is rotated is made equivalent to the waveform signal described with reference to FIGS. 5A and 5B. Can be done.
例えば、光沢面12aは、フォトリフレクタ10a,10bの発光部から光沢面12aへ投光したときの光沢面12aからの反射光をフォトリフレクタ10a,10bの受光部で検知可能な反射率に調整される。シート31の光沢面31aは、光沢面12aと同等の反射率に調整される。一方、シート31の非光沢面31bは、フォトリフレクタ10a,10bの発光部から非光沢面31bへ投光したときの非光沢面31bからの反射光をフォトリフレクタ10a,10bの受光部で検知不可能な反射率に調整される。 For example, the glossy surface 12a is adjusted to have a reflectance that allows the light reflected from the glossy surface 12a when the light emitted from the light emitting portions of the photoreflectors 10a and 10b to the glossy surface 12a to be detected by the light receiving portion of the photoreflectors 10a and 10b. To. The glossy surface 31a of the sheet 31 is adjusted to have the same reflectance as the glossy surface 12a. On the other hand, the non-glossy surface 31b of the sheet 31 does not detect the reflected light from the non-glossy surface 31b when the light is projected from the light emitting portion of the photoreflectors 10a and 10b to the non-glossy surface 31b by the light receiving portion of the photoreflectors 10a and 10b. Adjusted to possible reflectance.
これにより、回転操作環34が回転操作されたときの回転角度及び回転方向は、第1実施形態に係る回転操作環4が回転操作されたときの回転角度及び回転方向と同様に検知可能である。よって、回転操作環34でも、回転操作環4が奏する効果と同じ効果を得ることができる。 As a result, the rotation angle and the rotation direction when the rotation operation ring 34 is rotated can be detected in the same manner as the rotation angle and the rotation direction when the rotation operation ring 4 according to the first embodiment is rotated. .. Therefore, even with the rotation operation ring 34, the same effect as that of the rotation operation ring 4 can be obtained.
次に、本発明の第4実施形態に係る回転操作可能な操作部材について、図6(c)を参照して説明する。図6(c)は、本発明の第4実施形態に係る回転操作環44の内周面の平面展開図である。回転操作環44は、環状部材22と、環状部材22の内周面に貼り付けられたシート41とを有する。環状部材22は、第2実施形態で説明した環状部材22と同じであり、その内周面は非光沢面22aとなっている。 Next, the rotation-operable operating member according to the fourth embodiment of the present invention will be described with reference to FIG. 6 (c). FIG. 6C is a plan development view of the inner peripheral surface of the rotation operation ring 44 according to the fourth embodiment of the present invention. The rotation operation ring 44 has an annular member 22 and a sheet 41 attached to the inner peripheral surface of the annular member 22. The annular member 22 is the same as the annular member 22 described in the second embodiment, and its inner peripheral surface is a non-glossy surface 22a.
シート41の表面には、環状部材22の周方向に対応するシート41の長さ方向に、第1の反射率の第1の反射領域である幅Aの光沢面41aと、第2の反射率の第2の反射領域である幅Aの非光沢面41bとが、交互に並べられた構成となっている。シート41では、その長さ方向と直交する幅方向(図6(c)では上下方向)において、非光沢面41bが光沢面41aの一部に挟まれているが、幅方向端部側の光沢面41aは必ずしも必要なものではない。 On the surface of the sheet 41, a glossy surface 41a having a width A, which is a first reflection region of the first reflectance, and a second reflectance in the length direction of the sheet 41 corresponding to the circumferential direction of the annular member 22. The non-glossy surface 41b having a width A, which is the second reflection region of the above, is arranged alternately. In the sheet 41, the non-glossy surface 41b is sandwiched between a part of the glossy surface 41a in the width direction orthogonal to the length direction (vertical direction in FIG. 6C), but the gloss on the end side in the width direction The surface 41a is not always necessary.
シート41としては、全体が光沢面41aのシートに非光沢面41bを印刷等によって形成したもの、又は、全体が非光沢面41bのシートに光沢面41aを印刷等によって形成したものを用いることができるが、これに限定されるものではない。 As the sheet 41, a sheet having a non-glossy surface 41b formed on a sheet having a glossy surface 41a as a whole by printing or the like, or a sheet having a glossy surface 41a formed on a sheet having a non-glossy surface 41b as a whole by printing or the like can be used. Yes, but not limited to this.
環状部材22の内周面にシート41が貼り付けられた状態で、環状部材22の周方向で対向するシート41の両端間には、幅Bの隙間22bが形成される。シート41は、幅Bが幅Aと略等しくなる長さに設定されている。 With the sheet 41 attached to the inner peripheral surface of the annular member 22, a gap 22b having a width B is formed between both ends of the sheet 41 facing the annular member 22 in the circumferential direction. The sheet 41 is set to a length in which the width B is substantially equal to the width A.
シート41の表面の光沢面41a及び非光沢面41bの各反射率と、環状部材22の内周面の非光沢面22aの反射率との関係は、第3実施形態で説明した、シート31の表面の光沢面31a及び非光沢面31bの各反射率と環状部材12の内周面の光沢面12aの反射率との関係と同じである。よって、光沢面41a、非光沢面41b及び非光沢面22aの反射率は、非光沢面22aの反射率と非光沢面41bの反射率との差が、非光沢面31bの反射率と光沢面31aの反射率との差よりも小さくなるように設定される。これにより、回転操作環44が回転操作されたときにフォトリフレクタ10a,10bから得られる波形信号を、図5(a),(b)を参照して説明した波形信号の位相が半周期だけずれたものと同等にすることができる。 The relationship between the reflectances of the glossy surface 41a and the non-glossy surface 41b on the surface of the sheet 41 and the reflectance of the non-glossy surface 22a on the inner peripheral surface of the annular member 22 is described in the third embodiment of the sheet 31. The relationship between the reflectances of the glossy surface 31a and the non-glossy surface 31b on the surface and the reflectance of the glossy surface 12a on the inner peripheral surface of the annular member 12 is the same. Therefore, the reflectance of the glossy surface 41a, the non-glossy surface 41b, and the non-glossy surface 22a is such that the difference between the reflectance of the non-glossy surface 22a and the reflectance of the non-glossy surface 41b is the reflectance of the non-glossy surface 31b and the glossy surface. It is set to be smaller than the difference from the reflectance of 31a. As a result, the phase of the waveform signal obtained from the photoreflectors 10a and 10b when the rotation operation ring 44 is rotated is shifted by half a cycle as described with reference to FIGS. 5A and 5B. Can be equivalent to the one.
例えば、シート41の光沢面41aは、フォトリフレクタ10a,10bの発光部から光沢面41aへ投光したときの光沢面41aからの反射光をフォトリフレクタ10a,10bの受光部で検知可能な反射率に調整される。一方、シート41の両端間の隙間22bで露出する非光沢面22aは、フォトリフレクタ10a,10bの発光部から非光沢面22aへ投光したときの非光沢面22aからの反射光をフォトリフレクタ10a,10bの受光部で検知不可能な反射率に調整される。また、シート41の非光沢面41bは、非光沢面22aと同等の反射率を有するように調整される。 For example, the glossy surface 41a of the sheet 41 has a reflectance that allows the light receiving portion of the photoreflectors 10a and 10b to detect the reflected light from the glossy surface 41a when the light is projected from the light emitting portion of the photoreflectors 10a and 10b to the glossy surface 41a. Is adjusted to. On the other hand, the non-glossy surface 22a exposed by the gap 22b between both ends of the sheet 41 reflects the light reflected from the non-glossy surface 22a when the light is projected from the light emitting portion of the photoreflectors 10a and 10b onto the non-glossy surface 22a. , 10b is adjusted to a reflectance that cannot be detected by the light receiving unit. Further, the non-glossy surface 41b of the sheet 41 is adjusted so as to have the same reflectance as the non-glossy surface 22a.
これにより、回転操作環44が回転操作されたときの回転角度及び回転方向は、第1実施形態に係る回転操作環4が回転操作されたときの回転角度及び回転方向と同様に検知可能である。よって、回転操作環44でも、回転操作環4が奏する効果と同じ効果を得ることができる。 As a result, the rotation angle and rotation direction when the rotation operation ring 44 is rotated can be detected in the same manner as the rotation angle and rotation direction when the rotation operation ring 4 according to the first embodiment is rotated. .. Therefore, even with the rotation operation ring 44, the same effect as that of the rotation operation ring 4 can be obtained.
次に、本発明の第5実施形態に係る回転操作可能な操作部材について、図7(a)を参照して説明する。図7(a)は、本発明の第5実施形態に係る回転操作環54の内周面の平面展開図である。回転操作環54は、環状部材12と、環状部材12の内周面に貼り付けられたシート51から構成される。環状部材12は、第1実施形態で説明した環状部材12と同じであり、その内周面は光沢面12aとなっている。環状部材12についての詳細な説明は省略する。 Next, the rotation-operable operating member according to the fifth embodiment of the present invention will be described with reference to FIG. 7A. FIG. 7A is a plan development view of the inner peripheral surface of the rotation operation ring 54 according to the fifth embodiment of the present invention. The rotation operation ring 54 is composed of an annular member 12 and a sheet 51 attached to the inner peripheral surface of the annular member 12. The annular member 12 is the same as the annular member 12 described in the first embodiment, and its inner peripheral surface is a glossy surface 12a. A detailed description of the annular member 12 will be omitted.
シート51の表面は、非光沢面51aとなっている。また、シート51には、第1実施形態で説明したシート11と同様に、環状部材12の周方向に対応する長さ方向に、幅Aの孔部51bが幅Aの間隔で並べて形成されている。シート51が環状部材12に貼り付けられた状態で、環状部材12の周方向で対向するシート51の両端間には、幅Bの隙間12bが形成される。シート51は、幅Bが幅Aと略等しくなる長さに設定されている。 The surface of the sheet 51 is a non-glossy surface 51a. Further, in the sheet 51, similarly to the sheet 11 described in the first embodiment, holes 51b having a width A are formed side by side at intervals of the width A in the length direction corresponding to the circumferential direction of the annular member 12. There is. In a state where the sheet 51 is attached to the annular member 12, a gap 12b having a width B is formed between both ends of the sheet 51 facing the annular member 12 in the circumferential direction. The sheet 51 is set to a length in which the width B is substantially equal to the width A.
シート51の長さ方向の一方端には、他方端に向けて長さ方向に突出形成された第1の凸部51c及び第2の凸部51dが設けられている。第1の凸部51c及び第2の凸部51dはそれぞれ、環状部材12の周方向に対応するシート51の長さ方向において孔部51bと並ばない位置に設けられている。具体的には、第1の凸部51c及び第2の凸部51dはそれぞれ、シート51の長さ方向と直交する幅方向の両端部(図7(a)では上下の端部側)に設けられ、孔部51bは幅方向の中央部に設けられている。したがって、隙間12bでの光沢面12aの露出と孔部51bでの光沢面12aの露出を同等なものとすることができるため、回転操作環54でのフォトリフレクタ10a,10bによる回転検知に支障は生じない。シート51を環状部材12の内周面に貼り付けたときに、第1の凸部51c及び第2の凸部51dはそれぞれ、シート51の他方の端面に向けて突出する。 At one end of the sheet 51 in the length direction, a first convex portion 51c and a second convex portion 51d are provided so as to project in the length direction toward the other end. The first convex portion 51c and the second convex portion 51d are provided at positions not aligned with the hole portion 51b in the length direction of the sheet 51 corresponding to the circumferential direction of the annular member 12, respectively. Specifically, the first convex portion 51c and the second convex portion 51d are provided at both ends in the width direction orthogonal to the length direction of the sheet 51 (upper and lower end sides in FIG. 7A), respectively. The hole 51b is provided at the center in the width direction. Therefore, the exposure of the glossy surface 12a in the gap 12b and the exposure of the glossy surface 12a in the hole 51b can be made equivalent, so that the rotation detection by the photoreflectors 10a and 10b in the rotation operation ring 54 is hindered. Does not occur. When the sheet 51 is attached to the inner peripheral surface of the annular member 12, the first convex portion 51c and the second convex portion 51d each project toward the other end surface of the sheet 51.
第1の凸部51cの突出長さは、孔部51bの幅Aより短く、幅Aの半分(A/2)より長い。第2の凸部51dの突出長さは、孔部51bの幅Aより長く、幅Aの1.5倍より短い。そのため、環状部材12の内周面にシート51が貼り付けられた状態では、周方向において対向するシート11の他方の端面に対して、第1の凸部51cは重なることはないが、第2の凸部51dと重なった状態となる。 The protruding length of the first convex portion 51c is shorter than the width A of the hole portion 51b and longer than half (A / 2) of the width A. The protruding length of the second convex portion 51d is longer than the width A of the hole portion 51b and shorter than 1.5 times the width A. Therefore, in the state where the sheet 51 is attached to the inner peripheral surface of the annular member 12, the first convex portion 51c does not overlap with the other end surface of the sheets 11 facing each other in the circumferential direction, but the second It is in a state of overlapping with the convex portion 51d of.
第1の凸部51c及び第2の凸部51dは、環状部材12の内周面にシート51が適切に貼り付けられたか否かを判断する指標となる。例えば、第1の凸部51cがシート51の対向する端部と重なった場合には、シート51の一部が浮いた状態で貼り付けられたことになり、シート51の両端間の隙間12bの幅Bが、シート51に形成された孔部51bの幅Aより狭くなっていることになる。この場合には、回転操作環54の回転角度や回転方向を正確に検知することができなくなるおそれがあるため、シート51の貼り直しが必要なことがわかる。 The first convex portion 51c and the second convex portion 51d serve as indexes for determining whether or not the sheet 51 is properly attached to the inner peripheral surface of the annular member 12. For example, when the first convex portion 51c overlaps with the opposite end portion of the sheet 51, it means that a part of the sheet 51 is attached in a floating state, and the gap 12b between both ends of the sheet 51 The width B is narrower than the width A of the hole 51b formed in the sheet 51. In this case, the rotation angle and the rotation direction of the rotation operation ring 54 may not be accurately detected, so that it is necessary to reattach the sheet 51.
一方、第2の凸部51dがシート51の対向する端部と重ならなかった場合には、シート51が縒れて貼り付けられたことになり、シート51の両端間の隙間12bの幅Bが、シート51に形成された孔部51bの幅Aより広くなっていることになる。この場合も、回転操作環54の回転角度や回転方向を正確に検知することができなくなるおそれがあるため、シート51の貼り直しが必要なことがわかる。 On the other hand, when the second convex portion 51d does not overlap with the opposite end portion of the sheet 51, it means that the sheet 51 is twisted and attached, and the width B of the gap 12b between both ends of the sheet 51. However, the width A of the hole 51b formed in the sheet 51 is wider than the width A. In this case as well, it can be seen that the sheet 51 needs to be reattached because the rotation angle and rotation direction of the rotation operation ring 54 may not be accurately detected.
回転操作環54は、回転操作環4と同等の効果を得ることができ、また、簡便な方法でシート51が規定通りに環状部材12に貼り付けられているか否かを確認することができる。 The rotation operation ring 54 can obtain the same effect as the rotation operation ring 4, and it can be confirmed by a simple method whether or not the sheet 51 is attached to the annular member 12 as specified.
なお、第1の凸部51c及び第2の凸部51dの突出長さは、上述した範囲内で、部品の寸法誤差等のばらつきを考慮して設定される。具体的には、部品の寸法誤差等のばらつきが大きい場合、シート51の長さ方向の両端間に形成される隙間12bの幅Bを孔部51bの幅Aに可能な限り近付ける必要がある。つまり、第1の凸部51c及び第2の凸部51dの突出長さを幅Aに近付ける必要がある。この場合、シート51の貼りずれに対する許容量は小さくなる。 The protruding lengths of the first convex portion 51c and the second convex portion 51d are set within the above-mentioned range in consideration of variations such as dimensional errors of parts. Specifically, when there are large variations such as dimensional errors of parts, it is necessary to make the width B of the gap 12b formed between both ends of the sheet 51 in the length direction as close as possible to the width A of the hole 51b. That is, it is necessary to bring the protruding lengths of the first convex portion 51c and the second convex portion 51d closer to the width A. In this case, the allowable amount for the misalignment of the sheet 51 becomes small.
一方、部品の寸法誤差等のばらつきが小さい場合、シート51の長さ方向の両端間に形成される隙間12bの幅Bが孔部51bの幅Aから多少ずれていても、フォトリフレクタから出力される波形信号の位相差を、誤検知が発生しない許容範囲内に納めることができる。よって、第1の凸部51cは孔部51bの幅Aの半分の長さに近く、第2の凸部51dは幅Aの1.5倍の長さに近くすることができる。この場合、シート51の貼りずれに対する許容量は大きくなる。 On the other hand, when the variation such as the dimensional error of the parts is small, even if the width B of the gap 12b formed between both ends in the length direction of the sheet 51 is slightly deviated from the width A of the hole 51b, it is output from the photo reflector. The phase difference of the waveform signal can be kept within the allowable range where false detection does not occur. Therefore, the first convex portion 51c can be close to half the length of the width A of the hole portion 51b, and the second convex portion 51d can be close to 1.5 times the length of the width A. In this case, the allowable amount for the misalignment of the sheet 51 becomes large.
第1の凸部51c及び第2の凸部51dと同等の凸部を、図6(a),(b),(c)を参照して説明したシート21,31,41に設けることができる。また、回転操作環54では、シート51の長さ方向の一方の端面に第1の凸部51cと第2の凸部51dを形成したが、これに限られず、一方の端面に第1の凸部51cを形成し、他方の端面に第2の凸部51dを形成してもよい。このとき、第1の凸部51cと第2の凸部51dとが、環状部材12の周方向で重なり合わないようにする。更に、回転操作環4の光沢面と非光沢面とを逆にして回転操作環24を構成したのと同様に、回転操作環54の光沢面と非光沢面とを逆にしてもよい。 Convex portions equivalent to the first convex portion 51c and the second convex portion 51d can be provided on the sheets 21, 31 and 41 described with reference to FIGS. 6A, 6B and 6C. .. Further, in the rotation operation ring 54, the first convex portion 51c and the second convex portion 51d are formed on one end surface of the sheet 51 in the length direction, but the present invention is not limited to this, and the first convex portion is formed on one end surface. The portion 51c may be formed, and the second convex portion 51d may be formed on the other end face. At this time, the first convex portion 51c and the second convex portion 51d are prevented from overlapping in the circumferential direction of the annular member 12. Further, the glossy surface and the non-glossy surface of the rotation operation ring 54 may be reversed in the same manner as the rotation operation ring 24 is configured by reversing the glossy surface and the non-glossy surface of the rotation operation ring 4.
次に、本発明の第6実施形態に係る回転操作可能な操作部材について、図7(b)を参照して説明する。図7(b)は、本発明の第6実施形態に係る回転操作環64の内周面の平面展開図である。回転操作環64は、環状部材62と、環状部材62の内周面に貼り付けられたシート11から構成される。シート11は、第1実施形態で説明したシート11と同じであるので、詳細な説明を省略する。シート11が環状部材62の内周面に貼り付けられた状態で、シート11の長さ方向の両端間には、所定の幅Bの隙間62bが形成される。 Next, the rotation-operable operating member according to the sixth embodiment of the present invention will be described with reference to FIG. 7B. FIG. 7B is a plan development view of the inner peripheral surface of the rotation operation ring 64 according to the sixth embodiment of the present invention. The rotation operation ring 64 is composed of an annular member 62 and a sheet 11 attached to the inner peripheral surface of the annular member 62. Since the sheet 11 is the same as the sheet 11 described in the first embodiment, detailed description thereof will be omitted. In a state where the sheet 11 is attached to the inner peripheral surface of the annular member 62, a gap 62b having a predetermined width B is formed between both ends of the sheet 11 in the length direction.
環状部材62の内周面は、環状部材12の光沢面12aと同様の、光沢面62aとなっている。また、環状部材62の内周面には、第1のマーカ62c及び第2のマーカ62dが形成されている。図7(b)には、第1のマーカ62c及び第2のマーカ62dとして矩形の形状を有するものを示しているが、これに限定されるものではない。第1のマーカ62c及び第2のマーカ62dは、例えば、環状部材62に形成された凹部であるが、これに限定されるものではなく、刻印や印刷(インクの塗布)によって形成されてもよいし、シールを貼り付けることによって形成されていてもよい。 The inner peripheral surface of the annular member 62 is a glossy surface 62a similar to the glossy surface 12a of the annular member 12. Further, a first marker 62c and a second marker 62d are formed on the inner peripheral surface of the annular member 62. FIG. 7B shows, but is not limited to, the first marker 62c and the second marker 62d having a rectangular shape. The first marker 62c and the second marker 62d are, for example, recesses formed in the annular member 62, but are not limited thereto, and may be formed by engraving or printing (application of ink). However, it may be formed by attaching a sticker.
第1のマーカ62c及び第2のマーカ62dはそれぞれ、環状部材62の周方向でシート11に設けられた孔部11bと並ばない位置に設けられている。具体的には、第1のマーカ62c及び第2のマーカ62dはそれぞれ、環状部材62にシート11が貼り付けられたときのシート11の幅方向の両端部(図7(b)では上下の端部側)の近傍に設けられている。したがって、隙間62bでの光沢面62aの露出と孔部11bでの光沢面62aの露出を同等なものとすることができるため、回転操作環64でのフォトリフレクタ10a,10bによる回転検知に支障は生じない。 The first marker 62c and the second marker 62d are provided at positions not aligned with the holes 11b provided in the sheet 11 in the circumferential direction of the annular member 62, respectively. Specifically, the first marker 62c and the second marker 62d are both upper and lower ends in the width direction of the sheet 11 when the sheet 11 is attached to the annular member 62 (upper and lower ends in FIG. 7B), respectively. It is provided in the vicinity of the part side). Therefore, the exposure of the glossy surface 62a in the gap 62b and the exposure of the glossy surface 62a in the hole 11b can be made equivalent, so that the rotation detection by the photoreflectors 10a and 10b in the rotation operation ring 64 is hindered. Does not occur.
環状部材62の周方向での第1のマーカ62cの長さ(幅)は、シート11に形成された孔部11bの周方向の幅Aより短く、幅Aの半分(A/2)より長い。環状部材62の周方向での第2のマーカ62dの長さ(幅)は、孔部11bの周方向の幅Aより長く、幅Aの1.5倍より短い。そのため、環状部材62の内周面にシート11が貼り付けられた状態では、第1のマーカ62cがシート11と重なる(シート11で覆われる)ことはないが、第2のマーカ62dの一部は、シート11と重なる(シート11で覆われる)。 The length (width) of the first marker 62c in the circumferential direction of the annular member 62 is shorter than the circumferential width A of the hole portion 11b formed in the sheet 11 and longer than half (A / 2) of the width A. .. The length (width) of the second marker 62d in the circumferential direction of the annular member 62 is longer than the width A in the circumferential direction of the hole portion 11b and shorter than 1.5 times the width A. Therefore, when the sheet 11 is attached to the inner peripheral surface of the annular member 62, the first marker 62c does not overlap with the sheet 11 (covered by the sheet 11), but is a part of the second marker 62d. Overlaps the sheet 11 (covered by the sheet 11).
なお、本実施形態では、第1のマーカ62c及び第2のマーカ62dは、周方向での中心が環状部材62のスラスト方向と平行な直線M上に位置するように、環状部材62に形成されている。但し、第1のマーカ62c及び第2のマーカ62dを形成する位置は、これに限定されるものではなく、少なくとも、環状部材62のスラスト方向から見たときに第1のマーカ62cが第2のマーカ62dに包含される位置に形成されていればよい。 In the present embodiment, the first marker 62c and the second marker 62d are formed on the annular member 62 so that the center in the circumferential direction is located on the straight line M parallel to the thrust direction of the annular member 62. ing. However, the positions where the first marker 62c and the second marker 62d are formed are not limited to this, and at least the first marker 62c is the second marker 62c when viewed from the thrust direction of the annular member 62. It suffices if it is formed at a position included in the marker 62d.
第1のマーカ62c及び第2のマーカ62dは、環状部材62の内周面にシート11が適切に貼り付けられたか否かを判断する指標となり、また、環状部材62の内周面にシート11を貼り付ける際の目印となる。例えば、第1のマーカ62cの一部とシート11の長さ方向の端部とが重なった場合、シート11が環状部材62に対して浮いて貼り付けられたことになる。このとき、隙間62bの幅Bが、シート11に形成された孔部16bの幅Aより狭くなっていることになる。この場合には、回転操作環64の回転角度や回転方向を正確に検知することができなくなるおそれがあるため、シート11の貼り直しが必要なことがわかる。 The first marker 62c and the second marker 62d serve as indicators for determining whether or not the sheet 11 is properly attached to the inner peripheral surface of the annular member 62, and the sheet 11 is attached to the inner peripheral surface of the annular member 62. It will be a mark when pasting. For example, when a part of the first marker 62c and the end portion of the sheet 11 in the length direction overlap, the sheet 11 is floated and attached to the annular member 62. At this time, the width B of the gap 62b is narrower than the width A of the hole 16b formed in the sheet 11. In this case, since the rotation angle and the rotation direction of the rotation operation ring 64 may not be accurately detected, it can be seen that the sheet 11 needs to be reattached.
一方、第2のマーカ62dとシート11の長さ方向の端部とが全く重なっていない場合には、シート11が環状部材62に対して縒れて貼り付けられたことになる。このとき、隙間62bの幅Bが、シート11に形成された孔部11bの幅Aより広くなっていることになる。この場合も、回転操作環64の回転角度や回転方向を正確に検知することができなくなるおそれがあるため、シート11の貼り直しが必要なことがわかる。 On the other hand, when the second marker 62d and the end portion of the sheet 11 in the length direction do not overlap at all, the sheet 11 is twisted and attached to the annular member 62. At this time, the width B of the gap 62b is wider than the width A of the hole portion 11b formed in the sheet 11. In this case as well, it can be seen that the sheet 11 needs to be reattached because the rotation angle and the rotation direction of the rotation operation ring 64 may not be accurately detected.
なお、環状部材62の周方向での第1のマーカ62c及び第2のマーカ62dの長さ(幅)は、上述した範囲内で部品の寸法誤差等のばらつきを考慮して、第1の凸部51c及び第2の凸部51dの突出長さと同様に設定される。 The length (width) of the first marker 62c and the second marker 62d in the circumferential direction of the annular member 62 is the first convex in consideration of variations such as dimensional errors of parts within the above range. It is set in the same manner as the protruding length of the portion 51c and the second convex portion 51d.
本実施形態では、第1のマーカ62c及び第2のマーカ62dを、環状部材62の内周面にシート11を貼り付ける際の目印にしたが、これに代えて、凸部、印刷による印刷部或いは刻印による刻印部等であってもよい。また、第1のマーカ62c及び第2のマーカ62dを環状部材62のスラスト方向においてシート11が貼り付けられる幅の範囲内に設けたが、これに限られず、環状部材62のスラスト方向にずれた位置に第1のマーカ62c及び第2のマーカ62dを設けてもよい。 In the present embodiment, the first marker 62c and the second marker 62d are used as marks when the sheet 11 is attached to the inner peripheral surface of the annular member 62, but instead of this, a convex portion and a printing portion by printing are used. Alternatively, it may be a stamped portion or the like by stamping. Further, the first marker 62c and the second marker 62d are provided within the width range in which the sheet 11 is attached in the thrust direction of the annular member 62, but the present invention is not limited to this, and the second marker 62d is displaced in the thrust direction of the annular member 62. A first marker 62c and a second marker 62d may be provided at the positions.
以上の説明の通り、回転操作環64でも、回転操作環4と同等の効果を得ることができ、また、簡便な方法でシート11が規定通りに貼り付けられているか否かを確認することができる。 As described above, the rotation operation ring 64 can also obtain the same effect as the rotation operation ring 4, and it is possible to confirm whether or not the sheet 11 is attached as specified by a simple method. it can.
なお、回転操作環64において、回転操作環24で用いられているシート31を環状部材62の内周面に貼り付けた構成とすることもできる。また、環状部材62の内周面を非光沢面として第1のマーカ62c及び第2のマーカ62dを形成すると共に、シート21,41を環状部材62の内周面に貼り付けた構成とすることもできる。 In the rotation operation ring 64, the sheet 31 used in the rotation operation ring 24 may be attached to the inner peripheral surface of the annular member 62. Further, the inner peripheral surface of the annular member 62 is used as a non-glossy surface to form the first marker 62c and the second marker 62d, and the sheets 21 and 41 are attached to the inner peripheral surface of the annular member 62. You can also.
