2. Description of the Related Art An inexpensive film unit with a lens is provided so that a user can easily obtain a camera and take a picture even if he forgets to carry the camera. This lens-equipped film unit is equipped with a simple photographing mechanism including a photographing lens and a shutter, as well as a strobe device and a film winding mechanism, and a cartridge equipped with an international standard (ISO 1007-2079 version). It has a built-in film, is small and has excellent portability. Users who purchase this can easily enjoy taking pictures even indoors or in dark places.In addition, after the end of the shooting, they can hand over the whole unit to the development store without taking out the photographic film already taken. It has the advantage that it is only necessary to request the development, and it is not necessary to perform troublesome operations such as rewinding the film or taking out the cartridge. In such a film unit with a lens, a cartridge and a film drawn from the cartridge are stored in a roll form,
Each time a photo is taken, the film winding film is wound into the patrone by rotating the winding knob directly connected to the spool of the patrone.
And engage the perforation of the film,
The frame is wound to rotate the driven sprocket once and the cam that rotates coaxially with the driven sprocket for shutter charging and film winding stop. It is configured so that it cannot be done. Therefore, if the user forgets to wind the film, he may miss the photo opportunity.

In order to eliminate such an adverse effect, it is conceivable to use a motor like a general compact camera to automatically wind a film after shutter release. On the other hand, such a film unit with a lens, when the filming of the film with a cartridge is completed,
The film is taken out for collection and development in the developing station, and the unit main body is collected by the manufacturer after the film is taken out. In order to save resources and reduce costs, manufacturers disassemble the collected unit body, select reusable parts as they are, and reuse them, and separate the parts that cannot be reused as they are into raw materials. As a result, we are trying to recycle.

A lens-equipped film unit having such a film automatic feeding mechanism requires a power source for causing the strobe device to emit light and a power source for feeding the film. . However, providing these power sources separately in the film unit impairs the characteristics of the lens-equipped film unit, which are compact, highly portable, and inexpensive, which is not preferable. Therefore, it is conceivable to use one power source for both the power source for causing the strobe device to emit light and the power source for feeding the film. However, in this case, if the lead wires are directly soldered to both contact pieces of the battery that becomes the power source, it becomes difficult to remove the wiring board when disassembling the lens-equipped film unit and reassembling it. However, there is a problem that the reuse efficiency decreases. Further, in order to improve the reuse efficiency of the parts, it is possible that the parts of the film unit with a lens equipped with the automatic film feeding mechanism can be reused as the parts of the film unit with a lens of the manual winding type. Although desirable, if the lead wire is directly soldered to both contact pieces of the battery that becomes the power source, it becomes difficult to use the wiring board for the strobe device of the film unit with lens of the manual winding type. There was a problem.

At this time, the kicking-off arm 90d kicks the shutter blades 96, rotates the shutter blades 96, and opens the photographing opening 86. As a result, the subject light that has passed through the taking lens 9 reaches the film 20b, and the film 20b is exposed. Since the motor 30 is immediately stopped by the brake when the film is wound up one frame,
The film 20b is not pulled, and the blurring of the film does not occur during shutter release. At the same time, as shown in FIG. 3, the rotation of the locking lever 71 releases the pressing of the pin 72 against the switching lever 66 in the counterclockwise direction. As a result, the first contact piece 76 returns to its original shape due to its elasticity, and thus moves to the second contact piece 77 side. However, FIG.
As shown in FIG. 2, while the shutter button 5 is pressed down, the pressing piece 144a of the pressing lever 144 and the protruding piece 77a of the second contact piece 77 are not in contact with each other, so
The contact piece 77 is displaced in the direction away from the first contact piece 76 by its own elasticity, the contact portion 76a of the first contact piece 76 and the second contact piece 77 are not contacted, and the motor 30 is not rotated. .
