Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device loaded with a cartridge that is used as a cartridge chamber, and more particularly to a cartridge loading device provided with a safety lock mechanism for opening a cartridge chamber lid that closes the cartridge chamber. Is related to.

[0002]

2. Description of the Related Art There are cameras, film scanners, film developing devices, etc. as cartridge loading type devices, especially devices for loading a cartridge in which a photographic film is wound.

For example, in a camera, a cartridge chamber for loading a cartridge, a cartridge chamber cover for shielding the cartridge chamber, a driving means for feeding and rewinding a film from the loaded cartridge, a means for locking the cartridge chamber lid, and a cartridge chamber. An operation unit that unlocks the lid and opens the cartridge chamber lid is essential.

A photographic film used for a camera is required to have a light shielding property when it is not developed. For this reason, various proposals have been made regarding a safety lock mechanism for preventing the camera user from unintentionally opening the cartridge chamber lid after the photographic film is fed into the apparatus.

Japanese Unexamined Patent Publication No. 7-319057 proposes a safety lock mechanism that makes it impossible to accept a manual opening operation of the cartridge chamber lid opening operation section when the camera is in a special state such as a film winding state. .

According to Japanese Patent Laid-Open No. 7-128733, the cartridge chamber lid locking / unlocking operation portion is an electric switch, and the cartridge chamber lid is driven to open by electric control by a motor. Then, the cartridge chamber lid opening operation unit does not accept the cartridge chamber lid opening command. In other words, the sequence itself of opening the cartridge chamber lid by driving the motor is a safety lock mechanism.

[0007]

However, as is not the case with a camera, if a part of the gear train that feeds the photographic film bites or the electric control goes out of control, the film will not rewind into the cartridge. There is a possibility that there will be no status.

Further, because of the existence of the safety lock mechanism described above, when the above situation occurs in the safety lock state, there is a problem that even the cartridge chamber lid cannot be opened. Regardless of the state of the camera, it is extremely important for the function of the camera to completely rewind the film taken into the cartridge and remove the cartridge from the camera.

In Japanese Patent Laid-Open No. 7-319057, in the film winding state in which a safety lock is involved, the safety lock cannot be released or the cartridge chamber lid cannot be opened unless the camera is extensively released. If the camera is disassembled in a large scale, it takes time and labor, and there is also a problem in that the AF, the lens barrel, and the like are out of adjustment, and readjustment is required.

Also in the case of Japanese Patent Laid-Open No. 7-128733,
If electric current cannot be supplied to the drive motor due to an electrical trouble or the software runs out of control, the cartridge chamber cover cannot be opened unless the camera is extensively scattered.

Further, as disclosed in Japanese Patent Application Laid-Open No. 9-212598, as a workaround when a part of a gear train for feeding a film is stretched, a film in a cartridge is wound up. There is also a proposal to provide a work window for cutting the gear connection and a work window for manually driving the spool in the cartridge in order to drive the spool. However, despite the fact that the problem of the gear being stretched is an extremely rare phenomenon, it is possible to reduce the number of parts by providing multiple work windows and parts for sealing these work windows on the exterior of the device due to this problem. It was increasing and creating design difficulties. Even if the film is manually rewound into the cartridge, if the cartridge chamber lid lock release mechanism is not activated and the cartridge chamber lid unlocking operation is not accepted, the cartridge is easily removed from the device. I can't take it out.

The object of the present invention has been made in view of these problems. The appearance of the design is not impaired, it is not usually noticeable, the opening of the cartridge chamber lid can be quickly performed in an emergency, and new parts can be added. It is an object of the present invention to provide a cartridge loading type device such as a camera with a safety lock for a cartridge chamber lid which is unnecessary.
