2. Description of the Related Art By using a video camera, it is possible to capture still images as well as moving images. However, the resolution of the video camera is lower than that of the photo camera,
Often they want to use a photo camera (film camera) with a video camera. Therefore, it is conceivable that the video camera and the photo camera are integrally formed so that the video camera unit captures a moving image while the photo camera unit captures a still image.

In this case, it is necessary to dispose a total of two image pickup lenses of a video camera section and a photo camera section in the integrated camera device.

By the way, FIG. 11 is a diagram showing an outline of an electric zoom mechanism of a video camera. The operation body 81 is of a seesaw type, and tilts clockwise or counterclockwise around the fulcrum P as a center. Tact switches 82 and 83 are arranged at positions facing the lower surfaces of both ends of the operating body 81, respectively. Reference numeral 84 is a motor, and a zoom driver 85 is connected between the motor 84 and the tact switches 82 and 83. A gear 84a is attached to one end of the motor 84.

Reference numeral 86 is a zoom body having a substantially cylindrical shape. The zoom body 86 is provided with a gear 86a that meshes with the gear 84a of the motor 84. An image pickup lens 87 is fixed to the front side of the zoom body 86, and a zoom lens 88 that moves in the front-rear direction by the rotation of the gear 86a is disposed on the rear side thereof. When the operating body 81 is tilted and the tact switches 82 and 83 are pressed, the gear 84a of the motor 84 is rotationally driven. As a result, the gear 86a of the zoom body 86 rotates and moves the zoom lens 88 in the front-rear direction, so that the zoom operation is performed.

[0006]

As described above, in the camera device in which the video camera and the photo camera are integrated,
When the above-mentioned electric zoom function is applied to both imaging lenses, two operation bodies 81 are arranged on the cabinet.

In this case, when it is desired to zoom the zoom lenses of the video camera unit and the photo camera unit at the same time, the photo camera unit must be zoomed after the video camera unit is zoomed. This requires twice the time, smooth operation cannot be performed, and there is a risk of missing a photo opportunity.

Further, when the operation body for zooming the video camera section and the photo camera section is arranged separately from the cabinet, when the operation is switched from the video camera section to the photo camera section or vice versa, the camera The user has to move his / her finger to another operating body while checking the finger position while looking away from the eyecup of the device, which may make it impossible to perform a smooth operation.

Therefore, an object of the present invention is to enable smooth operation of electronic equipment and the like.

[0010]

According to the present invention, an operating body having a locking member and a pressing piece for locking a plurality of locking portions of a cabinet is arranged so as to be slidable and tiltable with respect to the cabinet and operated. The operated body is arranged at a position facing the pressing piece at a position where the locking member locks with the plurality of locking portions of the cabinet after the body slides.

[0011]

The lock between the locking member 34 of the operating body 30 and the locking portions 28a to 28c of the cabinet 1 is released, and the operating body 30 is slid in this released state. By locking the locking member 34 and any locking portions 28a to 28c of the cabinet 1, the operating body 30 is locked to the other locking portions 28a to 28c. When the operating body 30 is tilted, the operated bodies 51a to 51f arranged to face the pressing piece 31 of the operating body 30 are operated. Therefore, for example, when arranging the operated bodies 51e and 51f that simultaneously operate the pair of movable members 45 and 49, the pair of movable members 45 and 49 can be operated simultaneously. In addition, by sliding and tilting the operating body 30,
Since the operation of the electronic device can be switched, it can be operated smoothly without checking the finger position.
