Description

本発明は、操作部材への操作量に応じて当該操作部材に対応する機能のパラメータの変化量を変更することができる電子機器に関するものである。   The present invention relates to an electronic apparatus that can change a change amount of a parameter of a function corresponding to an operation member in accordance with an operation amount to the operation member.

従来、撮像装置のような電子機器において、撮影光学系の焦点距離を変更する機能、いわゆるズーム機能を有するものがある。このような撮像装置では、ズーム機能を実行するためのズーム操作部材が撮像装置外装部に設けられており、中立位置(非操作位置)から一方向に操作すると、撮影光学系の焦点距離をワイド方向に切替えることができる。あるいは、中立位置から他方向に操作すると、撮影光学系の焦点距離をテレ方向に切替えることができる。   2. Description of the Related Art Conventionally, some electronic devices such as an imaging apparatus have a function of changing a focal length of a photographing optical system, that is, a so-called zoom function. In such an imaging apparatus, a zoom operation member for performing a zoom function is provided on the exterior of the imaging apparatus, and when operated in one direction from the neutral position (non-operation position), the focal length of the imaging optical system is widened. You can switch to the direction. Alternatively, when the camera is operated in the other direction from the neutral position, the focal length of the photographing optical system can be switched to the tele direction.

また近年の撮像装置は、ズーム機能における焦点距離の変化速度(ズ−ム速度)を低速から高速へと可変できる撮像装置も提供されている。ズ−ム速度を可変できる撮像装置では、ズーム操作部材の移動量により、低速から高速へと段階的にズ−ム速度を制御しているのが一般的である。このような撮像装置においては、ズーム操作部材の移動量とズーム速度との関係がわかりづらく、低速ズームを意図しているのに高速ズームになってしまい過剰にズ−ムする等、意図したズ−ム倍率に合わせることが困難であった。   In recent years, imaging apparatuses that can change the focal length change speed (zoom speed) in the zoom function from low speed to high speed are also provided. In an imaging apparatus in which the zoom speed can be changed, the zoom speed is generally controlled stepwise from a low speed to a high speed by the amount of movement of the zoom operation member. In such an image pickup device, it is difficult to understand the relationship between the amount of movement of the zoom operation member and the zoom speed, and although the low-speed zoom is intended, the zoom is excessively zoomed because the high-speed zoom is caused. -It was difficult to match the magnification.

また、静止画のみならず動画撮影機能が搭載された撮像装置も提供されるようになり、ズ−ム倍率もより高倍率となってきている。こうした動画撮影中にズ−ム速度を可変できる高倍率のズーム機能を有する撮像装置においては、意図したズ−ム速度で制御できないと目標とするズーム倍率に達するまでに時間がかかり意図しない動画デ−タが記録されてしまう場合があった。   In addition, not only still images but also imaging devices equipped with a moving image shooting function have been provided, and the zoom magnification has become higher. In an imaging apparatus having a high-magnification zoom function that can change the zoom speed during moving image shooting, it takes time to reach the target zoom magnification unless it can be controlled at the intended zoom speed. -In some cases, data was recorded.

これらの問題に対し、特許文献1では、操作部材の移動量に応じてズ−ム速度を切替えるズ−ム速度切替え手段と、ズ−ム速度が切替わった時点から他のズ−ム速度に切替わる時点までの間で負荷を増加させる負荷増加手段を筐体に備えた撮像装置を提案している。   With respect to these problems, in Patent Document 1, zoom speed switching means for switching the zoom speed in accordance with the amount of movement of the operation member, and another zoom speed from the time when the zoom speed is switched. There has been proposed an imaging apparatus provided with a load increasing means for increasing the load until the time of switching.

しかしながら、上述の特許文献に開示された従来技術では、負荷増加手段は板バネ先端で当接させる構成となっており、当接させた瞬間の負荷は0で、その後、徐々に負荷を増加させている為、負荷を感じるまでの移動量が多い。そのため、操作者がズ−ム切替え位置を正確に把握しにくい。   However, in the prior art disclosed in the above-mentioned patent document, the load increasing means is configured to abut on the tip of the leaf spring, the load at the moment of abutment is 0, and then the load is gradually increased. Therefore, there is a lot of movement until you feel the load. For this reason, it is difficult for the operator to accurately grasp the zoom switching position.

そこで、本発明の目的は、操作部材への操作量に応じて当該操作部材に対応する機能のパラメータの変化量を変更することができる電子機器において、操作量と変化量との関係を操作者に把握しやすくすることを目的とする。   Accordingly, an object of the present invention is to provide a relationship between an operation amount and a change amount in an electronic device that can change a change amount of a parameter of a function corresponding to the operation member according to an operation amount on the operation member. The purpose is to make it easier to grasp.

The convex vertex of the bent portion approaches a straight line connecting the position where the arm portion is fixed to the operation member and the tip portion .

本発明によれば、操作部材への操作量に応じて当該操作部材に対応する機能のパラメータの変化量を変更することができる電子機器において、操作量と変化量との関係を操作者に把握しやすくすることができる。   According to the present invention, in an electronic device that can change the amount of change in the parameter of the function corresponding to the operation member according to the amount of operation on the operation member, the operator grasps the relationship between the operation amount and the amount of change. Can be easier.

次に、本実施形態における回転操作型のズ−ムレバ−ユニットについて図2ないし図6を用いて詳細に説明する。図2は本実施形態に係る撮像装置の展開図、図3は撮像装置におけるズームレバーユニットの展開図、図4はズームレバーユニットを下方から見た詳細図、図5はズームレバーユニットの縦方向の断面図である。   Next, the rotary operation type zoom lever unit in this embodiment will be described in detail with reference to FIGS. 2 is a development view of the imaging apparatus according to the present embodiment, FIG. 3 is a development view of the zoom lever unit in the imaging apparatus, FIG. 4 is a detailed view of the zoom lever unit viewed from below, and FIG. 5 is a vertical direction of the zoom lever unit. FIG.

ズ−ムレバ−ユニット33は、撮像装置本体1の上面に取り付けられる。前カバ−31および後カバ−32は、撮像装置本体1を覆う外装カバ−である。   The zoom lever unit 33 is attached to the upper surface of the imaging apparatus main body 1. The front cover 31 and the rear cover 32 are exterior covers that cover the imaging apparatus main body 1.

ズ−ムレバ−ユニット33は、シャッターボタン4と、圧縮バネ13と、ズ−ムレバ−5と、上面ベ−ス部材14と、ト−ションバネ15と、ズ−ムレバ−固定板17と、ズ−ム速度切替えブラシ18と、負荷増加板バネ19とで構成される。そして、直下に配置した操作プリント基板21とでシャッタースイッチ21aとズームスイッチ21bを構成する。本実施形態では更にメインスイッチ21c、モード設定スイッチ21dもあわせて構成しているが、説明は省略する。   The zoom lever unit 33 includes a shutter button 4, a compression spring 13, a zoom lever 5, an upper surface base member 14, a torsion spring 15, a zoom lever fixing plate 17, and a zoom lever. And a load increasing leaf spring 19. A shutter switch 21a and a zoom switch 21b are configured by the operation printed circuit board 21 arranged immediately below. In the present embodiment, the main switch 21c and the mode setting switch 21d are also configured, but the description is omitted.

シャッターボタン4は、シャッターボタン4の軸4bに、シャッターボタン4を上方向に付勢する圧縮バネ13を通して、フック4aでズ−ムレバ−5に抜け止めされている。シャッターボタン4は、操作者により押下された後、押下が解除されると圧縮バネ13の力で、待機位置に自動復帰する。   The shutter button 4 is secured to the zoom lever 5 by a hook 4a through a compression spring 13 that urges the shutter button 4 upward on the shaft 4b of the shutter button 4. After the shutter button 4 is pressed by the operator and then released, the shutter button 4 is automatically returned to the standby position by the force of the compression spring 13.

上面ベ−ス部材14は、モード設定レバー6と、電源ボタン7と、操作者の操作によって移動したズ−ムレバ−5を中立位置に復帰する復帰力を与えるト−ションバネ15が設けられている。ト−ションバネ15は、上面ベ−ス部材14の上面に設けた軸に、上方向から差し込まれ、両足が上面ベ−ス部材14の下側に潜り込むようにしてビス16で抜け止めされている。   The upper surface base member 14 is provided with a mode setting lever 6, a power button 7, and a torsion spring 15 for providing a restoring force for returning the zoom lever 5 moved by the operation of the operator to the neutral position. . The torsion spring 15 is inserted into the shaft provided on the upper surface of the upper surface base member 14 from above, and is secured with screws 16 so that both feet are under the upper surface base member 14. .

上面ベ−ス部材14には、ズ−ムレバ−5に設けたビス用の軸を通す複数の扇形の穴が設けられている。ズ−ムレバ−5のビス用の軸を、上側からこの穴に差込み、裏側からズ−ムレバ−固定板17を2本のビス20で固定する。したがって上面ベ−ス部材14はズ−ムレバ−5とズ−ムレバ−固定板17に挟まれている。   The upper surface base member 14 is provided with a plurality of fan-shaped holes through which the screw shafts provided in the zoom lever 5 are passed. A screw shaft of the zoom lever 5 is inserted into the hole from above, and the zoom lever fixing plate 17 is fixed with two screws 20 from the back side. Accordingly, the upper surface base member 14 is sandwiched between the zoom lever 5 and the zoom lever fixing plate 17.

このときズ−ムレバ−固定板17のレバ−形状部17aをト−ションバネ15の2本の腕の中央に引っ掛ける様に組み付ける。また、ズ−ムレバ−固定板17を固定する2本のビス20を締める際に、ズ−ム速度切替えブラシ18と負荷増加板バネ19をそれぞれ共締め固定する。ズ−ム速度切替えブラシ18と負荷増加板バネ19がズ−ムレバ−5と位置決めされることで、ズ−ム速度切替えブラシ18と負荷増加板バネ19は精度良く組みつけられる。またバランスよく配置することで互いの干渉が無く組立性も良い。   At this time, the lever-shaped portion 17 a of the zoom lever fixing plate 17 is assembled so as to be hooked on the center of the two arms of the torsion spring 15. Further, when the two screws 20 for fixing the zoom lever fixing plate 17 are tightened, the zoom speed switching brush 18 and the load increasing plate spring 19 are fixed together. By positioning the zoom speed switching brush 18 and the load increasing leaf spring 19 with the zoom lever 5, the zoom speed switching brush 18 and the load increasing leaf spring 19 are assembled with high accuracy. Also, by arranging them in a well-balanced manner, there is no interference with each other, and assembly is good.

ズ−ムレバ−5とズ−ムレバ−固定板17は一体固定となり、一体となったズ−ムレバ−固定板17は、上面ベ−ス部材14に対して、ズ−ムレバ−5に設けたビス用の軸を通す扇形の穴の範囲で回転自在に取り付けられている。   The zoom lever 5 and the zoom lever fixing plate 17 are integrally fixed. The integrated zoom lever fixing plate 17 is a screw provided on the zoom lever 5 with respect to the upper surface base member 14. It is attached so that it can rotate freely within the range of a fan-shaped hole that passes through the shaft.

これにより、ズ−ムレバ−固定板17は、ズ−ムレバ−5の操作に連動して回転動作する。ズ−ムレバ−5はト−ションバネ15の2本の腕の中央にズ−ムレバ−固定板17のレバ−形状部17aが位置するときに中立位置となる。ト−ションバネ15は、操作者の操作に応じて回動したズ−ムレバ−5を中立位置に戻すようにズームレバー5に対して所定の復帰力(回転操作に対する負荷)を付与している。   As a result, the zoom lever fixing plate 17 rotates in conjunction with the operation of the zoom lever 5. The zoom lever 5 is in a neutral position when the lever-shaped portion 17a of the zoom lever fixing plate 17 is located at the center of the two arms of the torsion spring 15. The torsion spring 15 applies a predetermined return force (load to the rotation operation) to the zoom lever 5 so as to return the zoom lever 5 rotated according to the operation of the operator to the neutral position.

ズ−ム速度切替えブラシ18は、ビス締め部18bが、樹脂で覆われるよう、金属と樹脂で構成されている。ズ−ム速度切替えブラシ18のブラシ部18aは、金属片でできており、先端が二股になった二本の接触子が形成されている。ビス締め部18bを、樹脂で覆う事で、ブラシ部18aがズ−ムレバ−固定板17に電気的に接触しないようにしている。   The zoom speed switching brush 18 is made of metal and resin so that the screw fastening portion 18b is covered with resin. The brush portion 18a of the zoom speed switching brush 18 is made of a metal piece, and two contactors having a bifurcated tip are formed. By covering the screw fastening portion 18b with resin, the brush portion 18a is prevented from being in electrical contact with the zoom lever fixing plate 17.

負荷増加板バネ19は、図4(b)に示すような形状をしており、ズームレバー5の回転中心とビス締め部19bの中心とを結ぶ直線aに対して線対称な1対の腕部19aが、ズームレバー固定板17と略平行に設けられている。本実施形態では、ズームレバー5の回転中心とビス締め部19bの中心とを結ぶ直線aはズームレバーの径方向と一致している。   The load increasing leaf spring 19 has a shape as shown in FIG. 4 (b), and a pair of arms symmetrical with respect to a straight line a connecting the rotation center of the zoom lever 5 and the center of the screw fastening portion 19b. A portion 19 a is provided substantially parallel to the zoom lever fixing plate 17. In the present embodiment, a straight line a connecting the rotation center of the zoom lever 5 and the center of the screw fastening portion 19b coincides with the radial direction of the zoom lever.

腕部19aは、直線aの近傍で負荷増加板バネ19に固定されていて、固定位置から直線aに対して略直交する方向に伸びている。そして、腕部19aには第1の折り曲げ部19c、第2の折り曲げ部19d及び第3の折り曲げ部19eが設けられていて、第1の折り曲げ部19cによって直線aに対して略直交する方向からビス締め部19b側に折り曲げられる。なお、第1の折り曲げ部19cでは、直線aに対して略直交する方向からの角度が90度を超えないように折り曲げることが望ましい。第1の折り曲げ部19cによって折り曲がった腕部19aは、更に第2の折り曲げ部19dによってズームレバーの回転方向と略平行な方向であって、腕部19aの先端部19fが直線aから離れる方向に折り曲げられる。そして、先端部19fの近傍に設けられた第3の折り曲げ部19eによって、先端部19fはズームレバー5の回転方向と略直交する方向であって、ズームレバー5の外周方向に折り曲げられる。このように、第1の折り曲げ部19cから第3の折り曲げ部19eまでの部分を屈曲部とすると、屈曲部と先端部19fとは連続して設けられ、屈曲部は腕部19aが固定された位置と先端部19fとを結んだ直線よりも後述する回転規制部側に凸となる。   The arm portion 19a is fixed to the load increasing leaf spring 19 in the vicinity of the straight line a, and extends in a direction substantially orthogonal to the straight line a from the fixed position. The arm portion 19a is provided with a first bent portion 19c, a second bent portion 19d, and a third bent portion 19e. From the direction substantially orthogonal to the straight line a by the first bent portion 19c. It is bent toward the screw fastening portion 19b. In addition, it is desirable to bend in the 1st bending part 19c so that the angle from the direction substantially orthogonal to the straight line a may not exceed 90 degree | times. The arm portion 19a bent by the first bent portion 19c is further in a direction substantially parallel to the rotation direction of the zoom lever by the second bent portion 19d, and the tip portion 19f of the arm portion 19a is separated from the straight line a. Can be folded. Then, by the third bent portion 19e provided in the vicinity of the front end portion 19f, the front end portion 19f is bent in the direction substantially orthogonal to the rotation direction of the zoom lever 5 and in the outer peripheral direction of the zoom lever 5. As described above, when the portion from the first bent portion 19c to the third bent portion 19e is a bent portion, the bent portion and the tip portion 19f are provided continuously, and the arm portion 19a is fixed to the bent portion. It is more convex toward the rotation restricting portion described later than a straight line connecting the position and the tip portion 19f.

これらのズ−ムレバ−ユニット33直下に操作プリント基板21が配置される。操作プリント基板21には、シャッタ−ボタン4の押し子4bで押下されるシャッタ−スイッチ21aと、ズ−ム速度切替えブラシ18の金属ブラシ部18aが摺動するズ−ム接点部21bと、他には、電源スイッチ21c、モ−ド接点部21d等を備えている。   The operation printed circuit board 21 is disposed immediately below these zoom lever units 33. The operation printed circuit board 21 includes a shutter switch 21a pressed by the pusher 4b of the shutter button 4, a zoom contact portion 21b on which the metal brush portion 18a of the zoom speed switching brush 18 slides, and others. Includes a power switch 21c, a mode contact portion 21d, and the like.

ズ−ム速度切替えブラシ18の金属ブラシ部18aは、操作プリント基板21のズ−ム接点部21b上を摺動移動し、操作者によるズ−ムレバ−5への操作角度(操作量)に応じて、非作動、ズ−ム動作方向の切替えと、ズ−ム速度の切替えを行う。   The metal brush portion 18a of the zoom speed switching brush 18 slides on the zoom contact portion 21b of the operation printed circuit board 21, and according to the operation angle (operation amount) to the zoom lever 5 by the operator. Inactive, switching of the zoom operation direction and switching of the zoom speed are performed.

次に、ズームレバー5を回転操作したとき生じる操作過重について図6を用いて説明する。図6(a)に示した中立位置からズ−ムレバ−5を所定角度だけ回転させると、図6(b)に示すように、負荷増加板バネ19の先端部19fが、上面ベ−ス部材14に形成された二本の回転規制部14aに当接する。先端部19fが回転規制部14aに当接した状態で更にズームレバー5を回転させると、ト−ションバネ15による復帰力に加え、負荷増加板バネ19による復帰力が追加される。この時、第2の折り曲げ部19dにより形成された腕部19aの『く』の字形状部分(屈曲部)が伸びることで塑性変形を防ぎ、先端部19fが回転規制部14aに当接した状態からわずかにズームレバー5を回転させただけで所望の負荷を生み出すことができる。   Next, the operation overload that occurs when the zoom lever 5 is rotated will be described with reference to FIG. When the zoom lever 5 is rotated by a predetermined angle from the neutral position shown in FIG. 6 (a), as shown in FIG. 6 (b), the tip 19f of the load increasing leaf spring 19 becomes the upper surface base member. 14 abuts against the two rotation restricting portions 14 a formed on the surface 14. When the zoom lever 5 is further rotated in a state where the front end portion 19f is in contact with the rotation restricting portion 14a, in addition to the restoring force by the torsion spring 15, the restoring force by the load increasing leaf spring 19 is added. At this time, the "<"-shaped part (bent part) of the arm part 19a formed by the second bent part 19d extends to prevent plastic deformation, and the tip part 19f is in contact with the rotation restricting part 14a. Thus, a desired load can be generated by rotating the zoom lever 5 slightly.

この復帰力の増加点からズ−ムレバ−5を更に回転操作すると、高速ズ−ム駆動状態が開始される。高速ズ−ム駆動状態が開始されてから更に回転操作していくと、図6(c)に示すように、ズ−ムレバ−5のビス締め用のボス5aと上面ベ−ス部材14に設けられた扇形の穴の端である突き当て部14bが当接し、それ以上の回転操作が不能となる。   When the zoom lever 5 is further rotated from the increasing point of the return force, the high speed zoom drive state is started. When the rotating operation is further performed after the high speed zoom driving state is started, as shown in FIG. 6C, the screw boss 5a and the upper surface base member 14 of the zoom lever 5 are provided. The abutting portion 14b, which is the end of the formed fan-shaped hole, comes into contact, and further rotation operation becomes impossible.

次に、ズームレバー5を回転操作したときのズーム速度の切替えについて説明する。ズ−ムレバ−5に力を加えト−ションバネ15の反力に抗して回転させると、ズ−ム速度切替えブラシ18の金属ブラシ部18aがズ−ム接点部21b上を摺動移動し、ズーム非作動の中立位置から低速ズ−ム域に入る。ズームレバー5の回転角度がこの低速ズーム域に入っている間は、第1のズーム速度でズーム倍率が変化する。   Next, switching of the zoom speed when the zoom lever 5 is rotated will be described. When a force is applied to the zoom lever 5 and rotated against the reaction force of the torsion spring 15, the metal brush portion 18a of the zoom speed switching brush 18 slides on the zoom contact portion 21b, Enter the low speed zoom range from the neutral position where zoom is not activated. While the rotation angle of the zoom lever 5 is in this low speed zoom range, the zoom magnification changes at the first zoom speed.

更にズームレバー5を回転させると、負荷増加板バネ19の先端部19fが上面ベ−ス部材14に形成された回転規制部14aに当接し、操作負荷が増加する。この回転角度を負荷増加点とする。この角度より更にズームレバー5を回転させることで、高速ズ−ム域に入る。ズームレバー5の回転角度がこの低速ズーム域に入っている間は、第1のズーム速度よりも速い第2のズーム速度でズーム倍率が変化する。すなわち、負荷増加点となる角度が低速ズ−ム/高速ズ−ムのズ−ム速度切替え点となる。   When the zoom lever 5 is further rotated, the distal end portion 19f of the load increasing leaf spring 19 comes into contact with the rotation restricting portion 14a formed on the upper surface base member 14, and the operation load increases. This rotation angle is taken as the load increase point. By rotating the zoom lever 5 further than this angle, the high speed zoom region is entered. While the rotation angle of the zoom lever 5 is within this low speed zoom range, the zoom magnification changes at a second zoom speed that is faster than the first zoom speed. That is, the angle that becomes the load increase point becomes the zoom speed switching point of the low speed zoom / high speed zoom.

このように、負荷増加点(第2の角度)とズーム速度切替え点(第1の角度)とを一致させることでズーム操作中の操作負荷の変化とズーム速度の変化とが対応し、操作者が操作負荷とズーム速度との関係を正確に把握することができる。そのため、操作者が所望するズーム速度を容易に設定することができ、目標とするズーム倍率に達するまでの時間を軽減することができる。   Thus, by matching the load increase point (second angle) and the zoom speed switching point (first angle), the change in the operation load during the zoom operation corresponds to the change in the zoom speed, and the operator Can accurately grasp the relationship between the operation load and the zoom speed. Therefore, the zoom speed desired by the operator can be easily set, and the time required to reach the target zoom magnification can be reduced.

なお、この負荷増加点とズ−ム速度切替え点とは完全に一致していなくてもよく、角度差が所定の範囲内(5°以内が望ましい)すなわち、負荷増加点とズ−ム速度切替え点とが略等しければ、操作者が操作負荷とズーム速度との関係を正確に把握することができる。   Note that the load increase point and the zoom speed switching point do not have to coincide completely, and the angle difference is within a predetermined range (preferably within 5 °), that is, the load increase point and the zoom speed switching point. If the points are substantially equal, the operator can accurately grasp the relationship between the operation load and the zoom speed.

図7は、ズ−ム速度切替え点と負荷増加点の関係を表す図である。なお、図7では、負荷増加点とズーム速度切替え点とが一致していない場合について説明する。   FIG. 7 is a diagram illustrating the relationship between the zoom speed switching point and the load increase point. FIG. 7 illustrates a case where the load increase point and the zoom speed switching point do not match.

ズームレバー5をシャッタースイッチ21aを中心に回転させると、ズ−ム速度切替えブラシ18の金属ブラシ部18aが操作プリント基板21に実装されたズーム接点部21bに接触導通し、ズーム非作動の中立位置Aから低速ズ−ム域Bに入る。更にズームレバー5を回転させると、低速ズ−ム域B移動中に、負荷増加板バネ19の先端部19fが上面ベ−ス部材14に形成された回転規制部14aに当接し、負荷増加点(中立位置から負荷増加点までの回転角度:D)となる。   When the zoom lever 5 is rotated about the shutter switch 21a, the metal brush portion 18a of the zoom speed switching brush 18 is brought into contact with the zoom contact portion 21b mounted on the operation printed circuit board 21, and the zoom non-actuated neutral position. Enter the low speed zoom zone B from A. When the zoom lever 5 is further rotated, the tip 19f of the load increasing leaf spring 19 abuts against the rotation restricting portion 14a formed on the upper surface base member 14 during the low speed zoom region B movement, and the load increasing point is increased. (Rotational angle from neutral position to load increase point: D).

この位置より更にズームレバー5を回転させることで、高速ズ−ム域Cに入る。この角度が低速ズ−ム/高速ズ−ムのズ−ム速度切替え点(中立位置からズ−ム切替え点までの回転角度:A+B)となる。すなわち、ズームレバー5の回転角度が第1の角度以上か否かに応じてズーム速度を切替える。   By further rotating the zoom lever 5 from this position, the high speed zoom region C is entered. This angle becomes the zoom speed switching point (rotational angle from the neutral position to the zoom switching point: A + B) of the low speed zoom / high speed zoom. That is, the zoom speed is switched according to whether the rotation angle of the zoom lever 5 is equal to or greater than the first angle.

上述したように、(A+B)とDとの角度差を所定の範囲内に設定することで、操作者が操作負荷とズーム速度との関係を正確に把握することができる。   As described above, by setting the angle difference between (A + B) and D within a predetermined range, the operator can accurately grasp the relationship between the operation load and the zoom speed.

(第2の実施形態)
次に、図8を参照して、本発明に係る第2の実施形態について説明する。なお、本実施形態では、第1の実施形態で説明した撮像装置とズームレバーユニット33の構成のみが異なるため、ズームレバーユニット33以外の構成についての説明は省略する。また、以下では、本実施形態のズームレバーユニット33において第1の実施形態のズームレバーユニット33と同様の部分は同じ符号をつけて説明するものとする。
(Second Embodiment)
Next, a second embodiment according to the present invention will be described with reference to FIG. In the present embodiment, only the configuration of the image pickup apparatus described in the first embodiment and the zoom lever unit 33 are different, and thus description of configurations other than the zoom lever unit 33 is omitted. Hereinafter, in the zoom lever unit 33 of the present embodiment, the same parts as those of the zoom lever unit 33 of the first embodiment will be described with the same reference numerals.

本実施形態では、ズ−ムレバ−5は、3本のカシメ軸5aが設けられ、上面ベ−ス部材14の上面から差込み、下面からズ−ムレバ−固定板17を取り付け、3本のカシメ軸5aを溶着することで、上面ベ−ス部材14を挟んで、回転自在に取り付けている。これにより、ズ−ムレバ−固定板17は、使用者によるズ−ムレバ−5の操作に連動して回転動作する。   In the present embodiment, the zoom lever 5 is provided with three caulking shafts 5a, inserted from the upper surface of the upper surface base member 14, and attached with the zoom lever fixing plate 17 from the lower surface. By welding 5a, the upper surface base member 14 is sandwiched and attached rotatably. As a result, the zoom lever fixing plate 17 rotates in conjunction with the operation of the zoom lever 5 by the user.

ズ−ムレバ−固定板17には、1対の板バネ形状部17bが設けられており、取り付ける際に、ズ−ムレバ−固定板17は、上面ベ−ス部材14の中立軸14cを2枚の板バネ形状部17bで挟むように組み込まれる。この2枚の板バネ形状部17bは、操作に応じて回動したズ−ムレバ−5を中立位置に戻るようにズームレバー5に対して所定の負荷(復帰力)を付与する。2枚の板バネ形状部17bの中央に、上面ベ−ス部材14の中立軸14cが位置するときにズ−ムレバ−5は中立位置となる。   The zoom lever fixing plate 17 is provided with a pair of leaf spring-shaped portions 17b. When the zoom lever fixing plate 17 is attached, the zoom lever fixing plate 17 has two neutral shafts 14c on the upper surface base member 14. It is assembled so that it may be pinched | interposed by the leaf | plate spring shape part 17b. The two leaf spring-shaped portions 17b apply a predetermined load (returning force) to the zoom lever 5 so that the zoom lever 5 rotated according to the operation returns to the neutral position. When the neutral shaft 14c of the upper surface base member 14 is positioned at the center of the two leaf spring-shaped portions 17b, the zoom lever 5 is in the neutral position.

また、ズームレバー固定板17には、第1の実施形態における負荷増加板バネ19の腕部19aと同形状の腕部17cが設けられている。   Further, the zoom lever fixing plate 17 is provided with an arm portion 17c having the same shape as the arm portion 19a of the load increasing leaf spring 19 in the first embodiment.

ズ−ムレバ−5を図8(a)に示した中立位置から所定角度だけ回転させると、図8(b)に示すように、腕部17cが上面ベ−ス部材14に形成された回転規制部14dに当接する。腕部17cが回転規制部14dに当接した状態で更にズームレバー5を回転させると、板バネ形状部17bによる復帰力に加え、腕部17cによる復帰力が追加される。この時、腕部17cの『く』の字形状部分(屈曲部)が伸びることで塑性変形を防ぎ、腕部17cが回転規制部14dに当接した状態からわずかにズームレバー5を回転させただけでも所望の負荷を生み出すことができる。   When the zoom lever 5 is rotated by a predetermined angle from the neutral position shown in FIG. 8 (a), as shown in FIG. 8 (b), the rotation restriction formed by the arm portion 17c on the upper surface base member 14 is achieved. It contacts the part 14d. When the zoom lever 5 is further rotated in a state where the arm portion 17c is in contact with the rotation restricting portion 14d, the restoring force by the arm portion 17c is added in addition to the restoring force by the leaf spring shape portion 17b. At this time, the "<"-shaped portion (bent portion) of the arm portion 17c extends to prevent plastic deformation, and the zoom lever 5 is slightly rotated from the state where the arm portion 17c contacts the rotation restricting portion 14d. Alone can produce the desired load.

この負荷増加点からズ−ムレバ−5を回転操作すると、高速ズ−ム駆動状態が開始され、更に回転操作していくと、図8(c)に示すようにズ−ムレバ−5のカシメ用のボスと上面ベ−ス部材14の突き当て部(不図示)が当接し、それ以上の回転操作が不能となる。   When the zoom lever 5 is rotated from this load increase point, a high speed zoom drive state is started. When the zoom lever 5 is further rotated, as shown in FIG. 8C, the zoom lever 5 is caulked. The boss and the abutting portion (not shown) of the upper surface base member 14 come into contact with each other, and further rotation operation becomes impossible.

ズ−ムレバ−固定板17には、更に、操作プリント基板に実装されたズ−ムスイッチ21bのレバ−部材を挟み込むように、突出部17dが形成されている。   The zoom lever fixing plate 17 is further provided with a projecting portion 17d so as to sandwich the lever member of the zoom switch 21b mounted on the operation printed board.

ズ−ムスイッチ21bは、角型で形成されたベ−ス部材に、レバ−部材が外形から突出しており、内蔵されたコイルバネ(不図示)によってレバ−部材を中立位置を保つように付勢している。レバ−部材は、一方の方向に回転させると、撮影レンズの焦点距離がテレ側(ズーム倍率が大きくなる方向)に変化し、他方の方向に回転させるとワイド側(ズーム倍率が小さくなる方向)に変化する。レバ−部材は操作者によるズ−ム動作を終了した後、内蔵されたコイルバネによって中立位置に復帰する。   The zoom switch 21b has a lever member protruding from an outer shape of a square base member, and urges the lever member to maintain a neutral position by a built-in coil spring (not shown). ing. When the lever member is rotated in one direction, the focal length of the photographic lens changes to the tele side (the direction in which the zoom magnification increases), and when rotated in the other direction, the wide side (the direction in which the zoom magnification decreases). To change. The lever member returns to the neutral position by a built-in coil spring after completing the zoom operation by the operator.

ズ−ムスイッチ21bは、ズ−ムレバ−固定板17の突出部17dの回動に伴い、ズ−ム動作への切替えと、ズ−ム速度を低速ズ−ム/高速ズ−ムの切替えを行うものである。   The zoom switch 21b performs switching to the zoom operation and switching the zoom speed between the low speed zoom and the high speed zoom as the protrusion 17d of the zoom lever fixing plate 17 rotates. Is.

このように、ズ−ムレバ−固定板17には、中立位置に復帰させる板バネ形状部17bと、回転操作の負荷を増加させる腕部17cと、ズ−ムスイッチ21bを作動させる突出部17dが一体で構成される為、精度良く、また組立性良く配置することが可能となる。   As described above, the zoom lever fixing plate 17 is integrally provided with the leaf spring-shaped portion 17b for returning to the neutral position, the arm portion 17c for increasing the load of the rotation operation, and the protruding portion 17d for operating the zoom switch 21b. Therefore, it can be arranged with high accuracy and good assembly.

操作者がズ−ムレバ−5に力を加えズームレバー5を回転させると、ズ−ムレバ−固定板17の突出部17dがズ−ムスイッチ21bを作動させ、中立位置から低速ズ−ム域に入る。ズ−ムレバ−固定板17の腕部17cが上面ベ−ス部材14に形成された回転規制部14dに当接し、操作負荷が増加する。その後更にズームレバー5を回転させると低速ズ−ム/高速ズ−ムのズ−ム速度切替え点を越える。この負荷増加点と、低速ズ−ム/高速ズ−ムのズ−ム速度切替え点を略等しく(角度差が5°以内が望ましい)設定することで、操作者が操作負荷とズーム速度との関係を正確に把握することができる。   When the operator applies a force to the zoom lever 5 and rotates the zoom lever 5, the projection 17d of the zoom lever fixing plate 17 operates the zoom switch 21b to enter the low speed zoom region from the neutral position. . The arm portion 17c of the zoom lever fixing plate 17 comes into contact with the rotation restricting portion 14d formed on the upper surface base member 14, and the operation load increases. Thereafter, when the zoom lever 5 is further rotated, the zoom speed switching point of the low speed zoom / high speed zoom is exceeded. By setting the load increase point and the zoom speed switching point of the low speed zoom / high speed zoom substantially equal (preferably the angle difference is within 5 °), the operator can set the operation load and the zoom speed. The relationship can be grasped accurately.

(第3の実施形態)
次に、図9を参照して、本発明に係る第3の実施形態について説明する。なお、本実施形態では、第1の実施形態で説明した撮像装置とズームレバーユニット33の構成のみが異なるため、ズームレバーユニット33以外の構成についての説明は省略する。また、以下では、本実施形態のズームレバーユニット33において第1の実施形態のズームレバーユニット33と同様の部分は同じ符号をつけて説明するものとする。
(Third embodiment)
Next, a third embodiment according to the present invention will be described with reference to FIG. In the present embodiment, only the configuration of the image pickup apparatus described in the first embodiment and the zoom lever unit 33 are different, and thus description of configurations other than the zoom lever unit 33 is omitted. Hereinafter, in the zoom lever unit 33 of the present embodiment, the same parts as those of the zoom lever unit 33 of the first embodiment will be described with the same reference numerals.

本実施形態では、上面ベ−ス部材14には、ズ−ムレバ−5を中立位置に復帰する復帰力を与えるト−ションバネ15が設けられている。ト−ションバネ15は、上面ベ−ス部材14上面に設けた軸に、上方向から差し込まれ、両足が上面ベ−ス部材14の下側に潜り込むようにしてビス16で抜け止めされている。   In the present embodiment, the upper surface base member 14 is provided with a torsion spring 15 for providing a restoring force for returning the zoom lever 5 to the neutral position. The torsion spring 15 is inserted from above into a shaft provided on the upper surface of the upper surface base member 14, and is prevented from being removed by screws 16 so that both feet are under the upper surface base member 14.

ズ−ムレバ−5は、上面ベ−ス部材14を挟むようにして、ズ−ムレバ−固定板17と2本のビス20によって固定され、上面ベ−ス部材14に対して回転自在に取り付けられる。これにより、ズ−ムレバ−固定板17は、ズ−ムレバ−5の操作に連動して回転動作する。   The zoom lever 5 is fixed by a zoom lever fixing plate 17 and two screws 20 so as to sandwich the upper surface base member 14, and is rotatably attached to the upper surface base member 14. As a result, the zoom lever fixing plate 17 rotates in conjunction with the operation of the zoom lever 5.

ズ−ムレバ−固定板17は、取り付ける際にレバ−形状部17aをト−ションバネ15の2本の腕の中央に引っ掛ける様に組み付けられる。ズ−ムレバ−5は、このト−ションバネ15の2本の腕の中央にズ−ムレバ−固定板17のレバ−形状部17aが位置するときに中立位置となる。ト−ションバネ15は、操作者の操作により回動したズ−ムレバ−5を中立位置に戻るように所定の復帰力を与える。   The zoom lever fixing plate 17 is assembled so that the lever-shaped portion 17a is hooked on the center of the two arms of the torsion spring 15 when attached. The zoom lever 5 is in a neutral position when the lever-shaped portion 17a of the zoom lever fixing plate 17 is located at the center of the two arms of the torsion spring 15. The torsion spring 15 gives a predetermined restoring force so that the zoom lever 5 rotated by the operation of the operator returns to the neutral position.

ズ−ムレバ−固定板17を固定する2本のビス20は、ズ−ム速度切替えブラシ18と負荷増加ゴムバネ29をそれぞれ共締め固定する。これによって、ズ−ム速度切替えブラシ18と負荷増加ゴムバネ29を精度良く、また組立性良く配置することが可能となる。   The two screws 20 for fixing the zoom lever fixing plate 17 fasten and fix the zoom speed switching brush 18 and the load increasing rubber spring 29 together. As a result, the zoom speed switching brush 18 and the load increasing rubber spring 29 can be arranged with high accuracy and good assembly.

ズ−ム速度切替えブラシ18は、ビス締め部18bが、樹脂で覆われるよう、金属と樹脂の二色成形で構成されている。ズ−ム速度切替えブラシ18のブラシ部18aは、金属片でできており、先端が二股になった二本の接触子が形成されている。ビス締め部18bを、樹脂で覆う事で、ブラシ部18aがズ−ムレバ−固定板17に電気的に接触しないようにしている。   The zoom speed switching brush 18 is formed by two-color molding of metal and resin so that the screw fastening portion 18b is covered with resin. The brush portion 18a of the zoom speed switching brush 18 is made of a metal piece, and two contactors having a bifurcated tip are formed. By covering the screw fastening portion 18b with resin, the brush portion 18a is prevented from being in electrical contact with the zoom lever fixing plate 17.

負荷増加ゴムバネ29は、エラストマ−など小さな力で大きく変形し、大きな弾性ひずみ領域を持った材料で構成している。負荷増加ゴムバネ29は、ズームレバー5の回転中心とビス20でビス締めされる不図示のビス締め部の中心とを結ぶ直線bに対して線対称な1対の腕部29aが、ズームレバー固定板17と略平行に設けられている。腕部29aは、直線bの近傍で負荷増加ゴムバネ29に固定されていて、固定位置から直線bに対して略直交する方向に伸びている。そして、腕部29aの先端部29bは、ズームレバー5の回転方向と略直交する方向であって、ズームレバー5の外周方向に折り曲げられる。本実施形態でも、第1の実施形態及び第2の実施形態の屈曲部に相当する、腕部29aが固定された位置と先端部29bとを結んだ直線よりも後述する回転規制部側に凸となる部分が設けられている。   The load increasing rubber spring 29 is made of a material having a large elastic strain region that is greatly deformed by a small force such as an elastomer. The load increasing rubber spring 29 has a pair of arm portions 29a which are symmetrical with respect to a straight line b connecting the rotation center of the zoom lever 5 and the center of a screw tightening portion (not shown) tightened with a screw 20 to fix the zoom lever. It is provided substantially parallel to the plate 17. The arm portion 29a is fixed to the load increasing rubber spring 29 in the vicinity of the straight line b, and extends in a direction substantially orthogonal to the straight line b from the fixed position. The distal end portion 29 b of the arm portion 29 a is bent in the direction substantially orthogonal to the rotation direction of the zoom lever 5 and in the outer peripheral direction of the zoom lever 5. Also in this embodiment, it protrudes toward the rotation restricting portion described later from a straight line connecting the position where the arm portion 29a is fixed and the tip portion 29b, which corresponds to the bent portion of the first embodiment and the second embodiment. The part which becomes is provided.

ズ−ム速度切替えブラシ18の金属ブラシ部18aは、操作プリント基板のズ−ム接点部上を摺動移動し、操作者によるズ−ムレバ−5への操作の回転角度(操作量)に応じてズ−ム動作への切替えと、ズ−ム速度を低速ズ−ム/高速ズ−ムの切替えを行う。   The metal brush portion 18a of the zoom speed switching brush 18 slides on the zoom contact portion of the operation printed board, and according to the rotation angle (operation amount) of the operation to the zoom lever 5 by the operator. Switching to zoom operation and switching the zoom speed from low speed zoom to high speed zoom.

図9(a)に示した中立位置からズ−ムレバ−5を所定の角度だけ回転させると、図9(b)に示すように、負荷増加ゴムバネ29は上面ベ−ス部材14に形成された二本の回転規制部14aに先端部29bが当接する。この時、負荷増加ゴムバネ29はエラストマ−などの弾性材料で構成されるため、先端部29bと回転規制部14aとの衝突音を軽減することができる。   When the zoom lever 5 is rotated by a predetermined angle from the neutral position shown in FIG. 9A, the load increasing rubber spring 29 is formed on the upper surface base member 14 as shown in FIG. 9B. The tip end portion 29b comes into contact with the two rotation restricting portions 14a. At this time, since the load increasing rubber spring 29 is made of an elastic material such as an elastomer, it is possible to reduce a collision sound between the tip portion 29b and the rotation restricting portion 14a.

先端部29bが回転規制部14a当接した状態で更にズームレバー5を回転させると、ト−ションバネ15による復帰力に加え、負荷増加ゴムバネ29による復帰力が追加される。この時、腕部29aの凸形状に起因する負荷増加ゴムバネ29の弾性力により、先端部29bが回転規制部14aに当接した状態からわずかにズームレバー5を回転させただけでも所望の負荷を生み出すことができる。   When the zoom lever 5 is further rotated with the distal end portion 29b in contact with the rotation restricting portion 14a, in addition to the restoring force by the torsion spring 15, the restoring force by the load increasing rubber spring 29 is added. At this time, due to the elastic force of the load increasing rubber spring 29 caused by the convex shape of the arm portion 29a, a desired load can be applied even if the zoom lever 5 is slightly rotated from the state where the tip end portion 29b is in contact with the rotation restricting portion 14a. Can be created.

この負荷増加点(先端部29bと回転規制部14aとが当接する回転角度)から更にズ−ムレバ−5を回転操作すると、高速ズ−ム駆動状態が開始される。高速ズ−ム駆動状態が開始されてから更に回転操作していくと、図9(c)のように、ズ−ムレバ−5のビス締め用のボス5aと上面ベ−ス部材14の突き当て部14bが当接し、それ以上の回転操作が不能となる。   When the zoom lever 5 is further rotated from this load increase point (the rotation angle at which the tip 29b and the rotation restricting portion 14a abut), the high-speed zoom drive state is started. When the rotating operation is further performed after the high speed zoom driving state is started, the boss 5a for tightening the screw of the zoom lever 5 and the upper surface base member 14 are abutted as shown in FIG. The part 14b comes into contact, and further rotation operation becomes impossible.

なお、上面ベ−ス部材14の突き当て部14bもエラストマ−などの弾性材料となるように周りの樹脂できた領域と2色成形されており、ズ−ムレバ−5のビス締め用のボス5aと上面ベ−ス部材14の突き当て部14b衝突音を軽減することができる。   The abutting portion 14b of the upper surface base member 14 is also molded in two colors with the surrounding resin region so as to be an elastic material such as an elastomer, and the screw lever boss 5a of the zoom lever 5 is formed. The impact noise of the abutting portion 14b of the upper surface base member 14 can be reduced.

このように、本実施形態では、ズームレバー5を回転させることで衝突する部分にエラストマ−などの弾性材料を配置することによって、音声録音時に録音されるズームレバーの操作音を軽減することができる。   As described above, in the present embodiment, the operation sound of the zoom lever that is recorded at the time of voice recording can be reduced by arranging the elastic material such as an elastomer in the collision portion by rotating the zoom lever 5. .

ズ−ムレバ−5に力を加えト−ションバネ15の反力に抗して回転させると、ズ−ム速度切替えブラシ18の金属ブラシ部18aは、操作プリント基板のズ−ム接点部21b上を摺動移動し、中立位置から低速ズ−ム域に入る。更にズームレバー5を回転させると負荷増加ゴムバネ29の先端部29bが上面ベ−ス部材14に形成された回転規制部14aに当接し、操作負荷が増加する。この回転角度が負荷増加点である。その後更にズームレバー5を回転させると低速ズ−ム/高速ズ−ムのズ−ム速度切替え点を越える。この負荷増加点と、低速ズ−ム/高速ズ−ムのズ−ム速度切替え点を略等しく(角度差が5°以内が望ましい)設定することで、操作者が操作負荷とズーム速度との関係を正確に把握することができる。   When a force is applied to the zoom lever 5 and rotated against the reaction force of the torsion spring 15, the metal brush portion 18a of the zoom speed switching brush 18 moves over the zoom contact portion 21b of the operation printed board. Slide and move from the neutral position to the low speed zoom range. When the zoom lever 5 is further rotated, the tip 29b of the load increasing rubber spring 29 comes into contact with the rotation restricting portion 14a formed on the upper surface base member 14, and the operation load increases. This rotation angle is the load increase point. Thereafter, when the zoom lever 5 is further rotated, the zoom speed switching point of the low speed zoom / high speed zoom is exceeded. By setting the load increase point and the zoom speed switching point of the low speed zoom / high speed zoom substantially equal (preferably the angle difference is within 5 °), the operator can set the operation load and the zoom speed. The relationship can be grasped accurately.

以上のように、上述した3つの実施形態では、ズーム速度の切替えを行うためのズ−ム速度切替え部材とズーム操作の負荷を増加させる負荷増加部材を精度良く、また組立性良く配置することができる。また、ズーム速度の切替え角度と略等しい角度でズーム操作の負荷を大きく変化させることで、操作者が操作負荷とズーム速度との関係を正確に把握することができる。   As described above, in the above-described three embodiments, the zoom speed switching member for switching the zoom speed and the load increasing member for increasing the load of the zoom operation can be arranged with high accuracy and ease of assembly. it can. Further, by greatly changing the zoom operation load at an angle substantially equal to the zoom speed switching angle, the operator can accurately grasp the relationship between the operation load and the zoom speed.

なお、上述した3つの実施形態では、撮像装置におけるズーム操作に適用した場合を説明したが、その他の機能の操作に適用しても構わない。例えば、記録媒体に記録された複数の画像のうちの1つを液晶表示装置11に表示させる再生モードにおいて、表示させる画像を次の画像に変更する画像送り操作の速度を変更させる場合に適用しても構わない。   In the above-described three embodiments, the case where the present invention is applied to the zoom operation in the imaging apparatus has been described. However, the present invention may be applied to operations of other functions. For example, in a playback mode in which one of a plurality of images recorded on a recording medium is displayed on the liquid crystal display device 11, it is applied when changing the speed of an image feed operation for changing the image to be displayed to the next image. It doesn't matter.

また、上述した画像送り操作のような、撮像装置以外の電子機器でも実行可能な機能にも適用可能であるため、操作部材への操作量に応じて当該操作部材に対応する機能のパラメータの変化量を変更させる電子機器であれば本発明を適用することができる。   In addition, since it can also be applied to a function that can be executed by an electronic device other than the imaging device, such as the image feed operation described above, the change in the parameter of the function corresponding to the operation member according to the operation amount to the operation member The present invention can be applied to any electronic device whose amount is changed.

また、上述した3つの実施形態では、操作部材の回転方向によらず、負荷増加及び変化量の変更を行ったが、操作部材を一方の方向に回転させたときのみ負荷増加及び変化量の変更を行う場合であっても適用可能である。   In the above-described three embodiments, the load increase and the change amount are changed regardless of the rotation direction of the operation member. However, the load increase and the change amount are changed only when the operation member is rotated in one direction. It is applicable even when performing.

また、上述した3つの実施形態では、変化量を2つで切替える(低速ズーム/高速ズーム)場合を説明したが、もっと多くの切り替えを行う場合に適用してもよく、例えば、第1の実施形態における負荷増加板バネ19を複数設けた構成であってもよい。   In the above-described three embodiments, the case where the change amount is switched between two (low speed zoom / high speed zoom) has been described. However, the present invention may be applied to a case where more changes are made, for example, the first embodiment. A configuration in which a plurality of load increasing leaf springs 19 are provided may be employed.

以上、本発明の好ましい実施形態について説明したが、本発明はこれらの実施形態に限定されず、その要旨の範囲内で種々の変形及び変更が可能である。   As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
