Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple self-timer which can be used only by mounting it on the upper surface of a camera such as a film with a lens (hereinafter referred to as a disposable camera).

[0002]

2. Description of the Related Art Most of the disposable cameras currently on the market do not have a self-timer function. Therefore, a self-timer mechanism for adding a self-timer function to such a camera later is proposed as a camera accessory. There is.

For example, there is a structure in which the shutter button is attached to a shutter button of a disposable camera and the shutter button is pushed down after a predetermined time by a shutter pushing member driven by a mainspring or the like to release the shutter.

However, since the self-timer mounted and used in the camera as described above needs to support at least the pressing force of the shutter button by the shutter pressing member, the camera body is used as a supporting body. Had to be formed in such a size that it could be covered from the outside, which made it bulky as a whole, and was inconvenient for storage and carrying.

Further, since it is necessary to incorporate a shutter button pressing mechanism using a mainspring or the like into the inside, the mechanism becomes complicated, and there is a problem that it takes time to manufacture.

Furthermore, the specifications (length, width, front and rear thickness) of the size of the disposable camera, the position of the shutter button, and the stroke of the shutter button are various depending on the manufacturer, and are therefore commercially available. However, if it could be applied to all the existing cameras, the structure would be rather complicated and the cost would have to be high.

[0007]

In view of the above-mentioned circumstances, the present invention can be mounted on the upper surface of each camera even if there is a difference in specifications regarding the size of the camera such as a disposable camera. It is an object of the present invention to provide a small and simple self-timer that can be used as it is.

[0008]

The present invention has been made for the purpose of solving the above-mentioned problems, and its constitution is as follows.
A suction cup member for holding the opened rear end side in a closed state against the spring force by the suction force on the open rear end side of the clip-shaped member formed so that the front end side is forcibly closed by the spring force. The clip-shaped member is closed outwardly by the suction force of the suction cup member, and the convex-shaped member contacts the shutter button of the camera. When the rear end side of the clip-shaped member which is brought into contact with and placed on the camera and closed by the suction force is explosively opened by the spring force, the opening force causes the convex member to push down the shutter button. It is characterized by having done.

[0009]

In the simple self-timer of the present invention, the rear end side of the clip-shaped member closed by the suction force of the suction cup member is burstly opened after an appropriate time so that the convex member pushes down the shutter button of the camera. Since the shutter can be released, it can be used with any manufacturer's camera regardless of the specifications regarding the size of the disposable camera, and it is compact and simple in structure, making it easy to carry. It does not get in the way and can also be used as a memo clip when not used as a self-timer.
