A multiple-type operation button integrally formed by an elastic member is sandwiched between the operation panel and a plurality of tact switches of the connector board, and even if another object collides with the multiple-type operation button, a shock or the like at that time occurs. Since the tactile switch is elastically absorbed so that the tact switch is not damaged and the switch guard surrounding the outer periphery of the operation panel can be removed, it is easy to directly press the multiple operation button with a fingertip. Therefore, the operability of the switch can be improved without using an operating jig.

Since the multiple operation button integrally formed by the elastic member can absorb the impact from the outside, the tact switch and the connector substrate can be prevented from being damaged.

The combination of the multiple operation button and the tact switch, which are integrally formed by the elastic member, provides a good switch operation feeling.

Since the switch device consisting of multiple operation buttons and a plurality of tact switches can be installed in a small space without taking up space, it is possible to promote miniaturization of the camera body and reduction of the number of parts.

Since the multiple operation buttons can be easily sandwiched between the operation panel and the plurality of tact switches, the multiple operation buttons can be easily assembled.

At this time, the rear end sides of the six operation buttons 35 are inserted into the six button mounting holes 29 formed in the operation panel 2d from the inner side to project rearward, and the front end sides of these operation buttons 35 are connected to the tact switches 36, respectively. To be attached to.

A positioning plate 40, which is a vertical bent piece integrally formed by bending, is provided on the lower surface of the rear end of the holding metal fitting 17, and the upper end side of the connector board 16 is located at the substantially central portion of the switch device 33. The positioning plate 40 is shown in FIG.
Are contacted in the direction of the arrow.

The switch device 33 configured as described above
Push the rear end of each operation button 35 from behind the operation panel 2d in the direction of the arrow shown in FIG.
At the front end of each of the tact switches 36, the tact switches 36 are pushed to be turned on, and when the fingertips are released from the operation buttons 35, the tact switches 36 are turned off.

At this time, the MENU button is used to display gain, shutter speed, white balance and other modes on the video screen, and the UP and DOWN buttons of the FUNCTION button are used to perform up and down operations of the displayed mode. , Set the specified mode. And UP button and DOWN of DATA button
Up and down the setting conditions of the mode set with the button. The DISPLAY button displays only the mode set on the video screen.

Since the positioning plate 40 of the holding member 17 can receive the pressing force when each operation button 35 is pressed in the arrow direction in FIG. 4 with the fingertip, the connector board 16 is bent in the arrow direction and damaged. Can be prevented.

Since the multiple-type operation button 38 is integrally formed by an elastic member such as a comb, even if the multiple-type operation button 38 is roughly handled or another object collides with it, the impact at that time is elastic. In this way, the tact switch 36 and the connector board 16 are not damaged.

Since the entire operation panel 2d is formed flat and there is no need to provide a switch guard surrounding the outer periphery of the operation panel 2d, it is easy to directly press each operation button 35 with a fingertip and the operability of the switch is good.

The combination of the multiple operation button 38 integrally formed by the elastic member and the plurality of tact switches 36 provides a good switch operation feeling.

The switch device 33 including the multiple operation buttons 38 and the plurality of tact switches 36 does not take up space and can be easily installed in a narrow space between the operation panel 2d and the connector board 16, so that the camera body 2 can be easily installed. It is possible to promote downsizing and reduction of the number of parts.

The multiple-type operation button 38 is easily fitted between the operation panel 2d and the plurality of tact switches 36 by fitting the plurality of operation buttons 35 into the plurality of button mounting holes 39 of the operation panel 2d from the inside. It is possible to easily assemble the multiple-type operation button 38.

The embodiment of the present invention has been described above.
The present invention is not limited to the above embodiments, and various modifications can be made based on the technical idea of the present invention.

[0045]

The video camera of the present invention constructed as described above has the following effects.

A multiple-type operation button integrally formed by an elastic member is sandwiched between the operation panel and a plurality of tact switches of the connector board, and even if another object collides with the multiple-type operation button, a shock or the like at that time occurs. Since the tactile switch is elastically absorbed so that the tact switch is not damaged and the switch guard surrounding the outer periphery of the operation panel can be removed, it is easy to directly press the multiple operation button with a fingertip. Therefore, the operability of the switch can be improved without using an operating jig.

Since the multiple operation button integrally formed by the elastic member can absorb the impact from the outside, the tact switch and the connector substrate can be prevented from being damaged.

The combination of the multiple operation button and the tact switch, which are integrally formed by the elastic member, provides a good switch operation feeling.

Since the switch device consisting of multiple operation buttons and a plurality of tact switches can be installed in a small space without taking up space, it is possible to promote miniaturization of the camera body and reduction of the number of parts.

Since the multiple operation buttons can be easily sandwiched between the operation panel and the plurality of tact switches, the multiple operation buttons can be easily assembled.
