The pressing rod for pressing the shutter button of the discard camera is formed so as to swingably support a substantially central portion in the longitudinal direction in a vertically swingable manner.

(Problems to be solved by the invention) However, when the self-timer is not used, the other end of the suction receiving plate is swung rearward about the pivotal support so that the pressing piece of the pressing rod moves to the true position of the shutter button. Since it is shifted from the top to the front, not only is the operation troublesome, but there is a risk that the shutter button of the single-use camera may malfunction when some impact is applied to or brought into contact with the pressing rod.

Therefore, the present invention has been devised to solve the above-mentioned problems, and is a self-timer for a single-use camera that can reliably prevent malfunction of the shutter button of the single-use camera with extremely easy operation. The lock device of

(Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention provides a locking piece near the pressing piece of a pressing plate for pressing a shutter button of a used camera, while On the rear side of the shutter button side end of the board fitted near one side of the shutter button on the camera upper surface, a lock body having a locking portion on the upper surface is pressed when the locking portion moves to the shutter button side. It is movably attached so that it can be engaged with and disengaged from the locking piece of the plate.

(Operation) When the self-timer is not used, the lock body is moved to the shutter button side by the above-described technical means, and the locking portion is locked to the locking piece of the pressing plate to operate the self-timer. Allow to lock. Further, when the self-timer is used, the lock body is moved to the opposite side of the shutter button so that the locking portion is disengaged from the locking piece of the pressing plate so that the self-timer can be released.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 5, first, a rectangular substrate 1 that is fitted on the upper surface of the disposable camera A near one side of the shutter button B is provided, and the shutter button B of the substrate 1 is provided.
A protrusion-shaped ventilation part 2 is provided on the upper surface of the opposite side end to a suitable length. Also, at the end of the upper surface of the substrate 1 on the shutter button B side, the shutter button B of the disposable camera A is attached to one end.
A pressing plate 5 having a pressing piece 3 for pressing and a suction cup 4 adsorbed to the upper surface of the ventilation part 2 of the substrate 1 at the other end is provided with a substantially central portion in the longitudinal direction via a pair of bearings 6 and a shaft pin 7. The shaft pin 7 has one end supported on the upper surface of the substrate 1 on the ventilating portion 2 side and the other end supported on the lower surface of the pressing plate 5 on the suction cup 4 side. A coil spring 8 for detaching the suction cup 4 is provided to be elastically repellent.

In the disposable timer self-timer device formed as described above, the locking piece 9 is provided so as to project downward near the rear surface of the pressing piece 3 of the pressing plate 5. On the other hand, on the rear side of the end portion of the substrate 1 on the shutter button B side, a guide edge 10 having a substantially rectangular ring shape that is long in the left-right longitudinal direction of the substrate 1 is provided.
A pair of moving holes 11 are provided side by side in the inner front and rear portion of 0. Then, the locking piece 9 is provided on the upper surface of each moving hole 11 of the substrate 1.
Each claw piece 15 protruding from the front and rear edges of the lower surface of the lock body 14 having the locking portion 12 for locking and the finger hook 13 for moving
Is movably fitted within the range of the guide edge 10 so that the locking portion 12 is disengageably locked to the locking piece 9 of the pressing plate 5 when moving to the shutter button B side. It was done.

That is, in the self-timer locking device of the present invention, the suction cup 4 of the pressing plate 5 is coiled around the shaft pin 7 as a coil spring 8.
The air vent 2 of the substrate 1 swings downward while resisting the repulsive force of the substrate 1.
When air is adsorbed on the upper surface, air gradually enters the suction cup 4 from both sides of the ventilation part 2, and the suction capacity of the suction cup 4 becomes weaker.
After a certain period of time, the elastic force of the coil spring 8 causes the suction cup 4 to separate from the substrate 1, and the pressing piece 3 of the pressing plate 5 swings downward around the shaft pin 7 so that the shutter button B of the disposable camera A is released. Make sure that it is pressed vigorously. In this case, the time from when the suction cup 4 of the pressing plate 5 is adsorbed until the shutter button B of the used camera A is vigorously pressed is 5 seconds to 15 seconds.
The cross-sectional area of both sides of the ventilation part 2, the size of the suction cup 4, and the elastic force of the coil spring 8 are appropriately set so as to be about a second.

The ventilation part 2 of the substrate 1 is provided with a protrusion-shaped ventilation part 2 of an appropriate length on the upper surface of the substrate 1 on the side opposite to the shutter button B, and the suction plate 4 of the pressing plate 5 is connected to the ventilation part of the substrate 1. 2 is described and illustrated so that air is gradually introduced into the suction cup 4 from both sides of the ventilation part 2 when adsorbed on the upper surface thereof, but the invention is not limited thereto and the shutter button B of the substrate 1 is not limited thereto. When a slit-like ventilation part is provided on the upper surface of the opposite end at a suitable length, and when the suction cup 4 of the pressing plate 5 is adsorbed on the upper surface of this ventilation part, air is gradually introduced from the ventilation part into the suction cup 4. You may enter.

Next, the use state will be described. When setting the self-timer, the lock body 14 is moved to the side opposite to the shutter button B as shown in FIG. After releasing from the stop piece 9 and releasing it, the suction plate 4 of the pressing plate 5 is swung downward against the elastic force of the coil spring 8 and adsorbed on the upper surface of the ventilation part 2 of the substrate 1, whereby air is sucked. When the suction capacity of the suction cup 4 becomes weaker as the suction cup 4 gradually enters the inside, the suction cup 4 is separated from the substrate 1 by the elastic force of the coil spring 8 after a certain time, and the pressing piece 3 of the pressing plate 5 is moved downward. Since the shutter button B of the used camera A is swung to the urging force, the shutter button B of the used camera A is automatically released after a certain time.

As in one embodiment of the present invention, a substantially rectangular ring-shaped guide edge 10 that is long in the left-right longitudinal direction of the substrate 1 is provided on the rear side of the end portion of the substrate 1 on the shutter button B side. A pair of moving holes 11 are arranged side by side, and each of the moving holes 11 of the substrate 1 is provided with a respective claw piece 15 projecting from the front and rear edges of the lower surface of the lock body 14, and its locking portion 12 is on the shutter button B side. If it is movably fitted within the range of the guide edge 10 so as to be releasably locked to the locking piece 9 of the pressing plate 5 when moving to the position, the finger hook portion 13 on the upper surface of the lock body 14 is interlocked. Therefore, the moving operation of the lock body 14 can be performed easily, reliably and smoothly.

(Effect of the Invention) As described above, the present invention provides the locking piece 9 in the vicinity of the pressing piece 3 of the pressing plate 5 for pressing the shutter button B of the single-use camera A, while the shutter on the upper surface of the single-use camera A is provided. On the rear side of the shutter button B side end of the substrate 1 fitted in the vicinity of one side of the button B, a lock body 14 having a locking portion 12 on the upper surface is provided.
Since the locking portion 12 is movably attached to the locking piece 9 of the pressing plate 5 so as to be disengageably locked when the shutter button B is moved to the shutter button B side, the lock body is locked when the self-timer is not used. 14 to the shutter button B side,
Since the self-timer can be locked by an extremely easy operation of only locking the locking portion 12 to the locking piece 9 of the pressing plate 5, malfunction of the shutter button B of the disposable camera A can be reliably prevented. . Further, when using the self-timer, the lock body 14 is moved to the opposite side of the shutter button B, and the self-timer is released by an extremely easy operation of only removing the locking portion 12 from the locking piece 9 of the pressing plate 5. As a result, the pressing operation of the shutter button B of the disposable camera A can be surely performed.
