A protrusion 6b is integrally provided on a part of an accessory shoe cover 6 that covers a contact point portion 5a of an accessory shoe 5 provided on the camera body 1, and the protrusion 6b is internally provided in a concave hole 8 of the camera body 1. When operating the operation switch, here the film rewinding switch 9, the protrusion 6b of the accessory shoe cover 6 is inserted into the recessed hole 8 to operate the switch. Therefore, it is possible to operate the switch in a correct state at any time by using the parts attached to the camera.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a camera having an accessory shoe, and more particularly, to improvement of a shoe cover provided to cover a contact portion of the accessory shoe.

[0002]

[Prior Art]

 A camera having an electric film rewinding mechanism or a date imprinting mechanism is provided with a film rewinding switch for forcibly rewinding the film and a date setting switch for imprinting the date. In this case, if these switches are exposed on the surface of the camera body, you may inadvertently operate the switches while operating the camera, causing the date to change unexpectedly or the film to rewind. Will be done. For this reason, in recent years, it has been proposed that a concave hole is provided on the surface of the camera body, and the operation switch, which is rarely used, is provided in the concave hole. With this configuration, there is no risk of inadvertently operating the switch in the recessed hole with a pointed object.

[0003]

[Problems to be solved by the device]

 In such a camera, a sharp object is required when operating the operation switch, so it becomes difficult to set the date and rewind the film when such an object is not held. Also, it is common to operate the switch with the tip of a mechanical pencil, but if the switch is operated with the core left open, the broken core may be caught in the switch and interfere with the normal operation of the switch. ..

Recently, a rubber contact has been proposed for the operation switch. In such a case, however, when the switch is operated with a pointed and hard object such as a ballpoint pen, the rubber contact is used. Doing so may cause holes in the contacts, resulting in poor contact, which may cause the camera to malfunction. An object of the present invention is to provide an accessory shoe cover attached to a camera as a component that can operate the operation switch in a correct state.

[0005]

[Means for Solving the Problems]

 According to the present invention, a part of the accessory shoe cover that covers the contact part of the accessory shoe provided on the camera body is provided with a protrusion that is inserted into the recessed hole in which the operation switch is installed to operate the operation switch. There is.

【Example】

 Next, the present invention will be described with reference to the drawings. FIG. 1 is a schematic perspective view of a camera to which the present invention is applied, where 1 is a camera body and 2 is a lens. Here, an example in which the present invention is applied to a single-lens reflex camera is shown. The camera body 1 is provided with a shutter button 3, a display 4, etc., and an accessory shoe 5 is provided on one shoulder. The accessory shoe 5 has a well-known structure, and a flash device (not shown) can be fitted and supported for electrical connection with the camera side.

An accessory shoe cover 6 that is attachable to and detachable from the camera body 1 is attached to the accessory shoe 5. In the attached state, the accessory shoe cover 6 covers the contact portion 5 a of the accessory shoe 5. , Prevent its exposure. This accessory shoe cover 6 is made of an insulating material such as a resin material, and is subjected to the same or similar surface treatment as the camera body 1 so as not to cause a feeling of strangeness when attached to the accessory shoe 5. preferable. As shown in the enlarged view of FIG. 2, the accessory shoe cover 6 has concave grooves 6a on both sides which are fitted to the rails 5b on both sides of the accessory shoe 5, and is attached to the accessory shoe 5. A projecting portion 6b having a sharpened tip is integrally formed at the end on the insertion side. The protrusion 6b is formed in a tapered shape as a whole, and when the accessory shoe cover 6 is attached to the accessory shoe 5, the protrusion 6b is housed in the recess 1a provided in the camera body facing the accessory shoe 5. There is.

On the other hand, one side of the camera body 1 is provided with a recessed hole 8 that is tapered together with the back cover opening lever 7, and a film rewind switch 9 is installed inside this recessed hole 8. This film rewinding switch 9 is provided on the surface of the flexible printed circuit board 12 arranged along the surface of the body 11 of the camera body 1, as shown in FIG. It is composed of rubber contacts 13 arranged. When the rubber contact 13 is pressed inward, the rubber contact 13 is elastically deformed to bring the circuit into conduction by contacting the contact of the flexible printed circuit board 12 with the conductive portion 13a, thereby turning on the circuit and turning it out of the drawing. The electric film rewinding mechanism of is driven to forcibly rewind the film.

Therefore, according to this structure, since the film rewind switch 9 is provided at a position retracted from the surface of the camera body 1, the film rewind switch 9 is manually operated during normal operation of the camera. No object is touched and unintentional forced rewinding of the film is prevented. When it becomes necessary to rewind the film, the accessory shoe cover 6 attached to the accessory shoe 5 is removed as shown in FIGS. 1 and 2, and then the accessory shoe cover 6 is attached as shown in FIG. The protrusion 6b provided integrally with the above is inserted into the recessed hole 8 and the rubber contact 13 therein is pressed. As a result, the rubber contact 13 is elastically deformed inward, the conductive portion 13a comes into contact with the flexible printed circuit board 12 to operate the film rewinding switch 9, and the film rewinding mechanism rewinds the film. ..

Therefore, by using the accessory shoe cover 6 that is always attached to the camera, it is possible to rewind the film at any time during shooting outdoors. Further, it is not necessary to use a mechanical pencil or other hard parts when rewinding the film, and it is possible to prevent the camera from being damaged due to the switch operation using these parts. Although the film rewind switch is used as an example of the operation switch in the above embodiment, it can be applied to the date setting switch of the date imprinting mechanism.

[0011]

[Effect of the device]

 As described above, according to the present invention, since the operation switch provided inside the recess can be operated by the protrusion provided on the accessory shoe cover, the accessory shoe cover normally attached to the camera is used. The operation switch can be operated at any time, and it is possible to avoid the cause of failure that occurs when operating the operation switch using other parts.
