Description

DETAILED DESCRIPTION OF THE INVENTION Recently, a disc camera (DISC CAMERA) has been developed. This camera is designed to rotate a disk containing film inside the camera. That is, a large number of film frames are provided at equal intervals along the circumference of a disk, and one such disk is housed in a predetermined cartridge. The cartridge is released from the locked room by being loaded into the camera, and the prescribed 7.
(The camera has a configuration in which the frame piece is placed in the photographic optical system, and when the shutter is opened and closed in this state, the photographing operation is performed. Also, in this camera, the disc rotates immediately after the shutter release and the next frame is released.)V Move the piece to the photographing optical system.

The above-mentioned camera is an example of a disk camera, but such a disk camera is already known, for example, as disclosed in U.S. Pat. No. 4,194.822 and U.S. Pat.
, No. 614.

The main characteristics of a disk camera are that it has a flat shape with an extremely small thickness, and that its structure is suitable for reducing size and weight. Therefore, this camera is extremely convenient to carry, use, and store, and is small and lightweight enough to be carried in a shirt pocket, for example.

However, since the development of disc cameras is new, there are many practical problems that need to be improved.

The problems are listed below.

(1) The shirt button has an electrical switch structure. This shirt button is advantageous in that it can be pushed and operated with a small stroke and light pressure, but it does not bend or bend.
There is a drawback that it is easy to operate incorrectly. That is, when preparing to take a picture or while carrying the camera in a pocket of clothing, the shirt button may be inadvertently pressed to trigger the shutter operation. Furthermore, some cameras with a built-in flash emitter automatically emit a flash when the brightness of the subject is below a predetermined level. A flash may occur along with the release, and in some cases, a flash may occur within the pocket in which the camera is placed.

(2) The disk camera is loaded and 2. It is flattened along the disc and has a rectangular shape with little depth when viewed from the front.The photographic lens is located on the right side of the front, and the light emitting window of the flashlight is located on the upper left side of the front. There are many things set up.

For this reason, it is structurally and operationally difficult to provide a shirt button on the top left side of the camera when viewed from the front, and also because this type of camera is placed on a tabletop with the shooting lens facing upward. If the shirt button is placed on the back of the camera, it may cause malfunction. For the above-mentioned reasons, the shirt button is generally provided approximately at the center of the front of the camera; however, it is not preferable to provide the shirt button at such a position because it is difficult to operate.

(3) As mentioned above, the disk camera has a flat shape with little thickness, but like other small cameras such as this one, the holding position when the shirt is released is unstable. So-called shutter shake is likely to occur.

(4) Since the disk camera has a flat shape,
The viewfinder window and the light emitting window of the flashlight emitter are likely to come into contact with other objects, and these windows may be scratched or damaged. For example, this is likely to occur when carrying a camera and other items together in a pocket of clothing.

The present invention aims to solve the above-mentioned drawbacks of disc cameras, and in order to stabilize the hand-holding posture when releasing the shirt, a retractable grip is provided on one side of the disc camera, and when the grip is retracted, , that is,
When the camera is not in use, the shutter button provided on the side of the camera is covered by the grip, and the camera is characterized in that it is configured to prevent the button from being accidentally operated while carrying the camera.

In addition, in a disc camera with a built-in flashlight, the above-mentioned grip covers the light-emitting window and the shirt button, thereby preventing the light-emitting window from being scratched or damaged due to contact with other objects. .

An embodiment of the disc camera according to the present invention will be described below with reference to the drawings.
