Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lens-equipped film unit, and more particularly to a lens-equipped film unit in which a motor winds a film.

[0002]

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 that is specified by the international standard (ISO 1007-1979 version). It has a built-in film, is small,
It has excellent portability. Users who purchase it can easily take pictures even indoors or in dark places.In addition, after the shooting is complete, the entire unit itself, without taking out the photographic film, can be handed over to the photofinishing shop. Therefore, there is an advantage that it is only necessary to request the development, and it is not necessary to perform troublesome operations such as rewinding the film and taking out the cartridge. Such a film unit with a lens stores a film cartridge and a film pulled out from the film cartridge in a roll form, and by rotating the winding knob directly connected to the spool of the film cartridge, the film cartridge is rotated every time a photograph is taken. It is configured to wind up the film that has already been taken.
And engage the perforation of the film,
Shutter charging and film winding stop are performed by the driven sprocket that makes one rotation by winding the frame and the cam that rotates coaxially with the driven sprocket, and the winding knob must be rotated for each shooting. It is configured so that the next shooting cannot be performed. For this reason, if the user forgets to wind the film after shooting, he or she may miss the photo opportunity.

In order to solve such a problem and make the photographing operation simpler, a motor is used like a general compact camera, and after shutter release,
It may be possible to automatically wind the film. In a general compact camera, the film winding motor winds the film one frame at a time, or at the time of loading the film, to wind the film from the patrone to the take-up shaft, or to finish shooting all the films. Later, in order to rewind the film into the patrone, if it has a zoom, it is also used for zooming, so stable performance is required,
In addition, since it is required to withstand repeated use and inevitably be compact, an expensive motor is used and is usually arranged in the film winding shaft.

[0004]

However, in the film unit with a lens, the film is stored in a state of being pulled out from the cartridge, and the film is wound after all the films have been photographed. It is sufficient for the film winding motor to be able to wind the film one frame at a time without needing to return it. Moreover, since it does not require repeated use as much as a compact camera, it can be used like a compact camera. , No need to use expensive motors. Furthermore, in the case of incorporating a motor similar to a compact camera in a film unit with a lens and automatically winding the film, contrary to the characteristic of the film unit with a lens that it is cheap, on the other hand, it is cheap, When using a large-sized motor, the characteristic of being compact may be impaired.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a cartridge storage chamber in which a cartridge with a film with a cartridge is stored, a film winding motor, a gear unit for transmitting the driving force of the motor, and a grip portion gripped at the time of photographing. A film unit with a lens including a lens unit, which is capable of automatically winding a film by a motor without impairing the characteristics of the film unit with a lens that is inexpensive and compact. To do.

[0006]

The above object of the present invention is achieved by arranging the motor in the front of the cartridge storage chamber and storing it in the grip portion. In a preferred embodiment of the present invention, the gear unit is arranged above the motor and the cartridge storage chamber.

[0007]

According to the present invention, the film winding motor is arranged at the front side of the cartridge storage chamber in which the cartridge is stored, and is stored in the grip portion which is gripped at the time of photographing. Even if a relatively large motor is used, the lens-equipped film unit does not unnecessarily increase in size, improving the operability during shooting, and at the same time, it is possible to automatically wind the film at a low cost. It becomes possible to provide. According to the preferred embodiment of the present invention, since the gear unit is arranged above the motor and the cartridge storage chamber, it is possible to provide a compact film unit with a lens capable of automatically winding a film.
