DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an efficient, automatic and miniaturized film rewinding device for rewinding a film from a new type of film cartridge to an intermediate cartridge.

[0002]

2. Description of the Related Art As a cartridge for storing a film, a so-called patrone of a cochlear shape, which is conventionally used with a terminal of the film slightly extended, is generally used.
However, such conventional ones have various problems when used,
Recently, a new type of cartridge has been disclosed in US Pat. No. 5,347,334 or US Pat. No. 5,031,8.
No. 52 has been proposed.

[0003] Although this new type of film cartridge is still cochlear in appearance, the cartridge case is downsized and a split type is adopted, and the film wound on a spool is opened as needed to open the case. And can be taken out freely. In addition to storing the unexposed raw film, it is considered that the negative film can be stored in the cartridge even after developing and printing after photographing.

[0004] Before the film is used for photography, the entire film is stored in a cartridge, the outlet for feeding out the film is completely closed by a lid which can be freely opened and closed, and at the time of photography, the lid is opened and the spool is rotated. The leading end of the film is fed out of the cartridge outlet by the spool output (thrust).

At the rear end of the film, a hole at the rear end of the film is locked by a locking claw projecting into a slit provided in the spool core, thereby securely fixing the film to the spool. or,
An edge material is provided on the spool flange for feeding the film, and between the flange and the inner wall of the case, the film is unexposed, exposed, developed, etc., and a bar code is displayed to prevent double exposure. For example, an arc-shaped disk plate or the like is provided.

The above-mentioned new type film cartridge M
Will be briefly described with reference to FIGS. This film cartridge M is described in U.S. Pat.
347, 334 and the like, and for the detailed configuration, see the original text.

As shown in FIG. 12, a film cartridge M comprises a cochlear-shaped cartridge case 100 having a built-in spool 101 for film winding, and the case 100 is divided into two halves as shown in FIG. Is different from the conventional patrone in that an opening / closing door 102 is provided at the film outlet. A rotation shaft is provided at one end of the spool 101 and the opening / closing door 102, and slots 103 and 104 are provided for connecting power shaft ends for transmitting power for rotating the respective rotation shafts.

Further, a spool 1 is provided at one end, which is the same as the above.
A fan-shaped indicator plate 105 is provided outside the flange of No. 01, and a to d indicate the state of the film depending on where the fan-shaped portion of the indicator plate 105 is located.
Are bored in the case end plate 106. The display hole a indicates an unexposed state (unphotographed), b indicates an unexposed state partially using the film, c indicates an exposed state (undeveloped), and d indicates a developed state. Any of the above states can be confirmed by the white fan-shaped portion of the indicator plate 105.

[0009] As shown in FIG.
The film F wound around the spool shaft 101b of No. 01 is shielded from light by closing the film outlet of the film case with the opening / closing door 102 while the entire length is wound. When rotated, the film F is fed out only by the rotation.

When winding the film F around the spool 101, as shown in FIG. 13B, the end of the film F is inserted into the slit 107 of the spool shaft 101b, and the hole h near the end is engaged with the engaging claw. Wrap with hooking on 108. When the entire length of the film is wound on the spool 101, the notch 109 at the beginning of the film is stopped by being hooked on the skirt of the flange 101c of the spool.

When the film stored in such a cartridge is developed and printed on the premise of the above-described film cartridge, the film fed from the film cartridge is directly sent to a developing device or a printing device, and the film is left as it is. Since the trailing end cannot be separated from the spool, the feeding is stopped at the end of the film, and the developing process cannot be performed efficiently and automatically. Therefore, as one method for efficiently performing the development processing without stopping the processing, an intermediate cartridge is prepared in advance, and the film is once wound around the intermediate cartridge.

A film unwinding device for winding a film around such an intermediate cartridge or a winding portion corresponding to the intermediate cartridge is known from Japanese Patent Application Laid-Open No. Hei 5-232633. In this unwinder, a film cartridge storage section and a film take-up section are provided at a predetermined distance, a film feed roller and a film guide are installed between them, and separate drive motors are attached to the film cartridge and the feed roller, respectively. Have been.

The leading end of the film is fed by rotating a spool in the cartridge by a motor for the film cartridge and sending it out. When the leading end of the film reaches the feed roller, the film is sent to the winding section by the motor for the feed roller. When the motor is fed to the rear end of the film, each motor stops. However, even after the motor stops, the spool slightly rotates in the film feeding direction due to the inertial force of the flywheel provided between the spool and the motor for the film cartridge.

Therefore, the rear end of the film is displaced with respect to the spool, and the hole at the rear end of the film is disengaged from the engaging pawl of the spool. Thereafter, when the motor of the feed roller is driven again to feed the film until the film comes off the feed roller, the film wound by the winding unit can be removed from the winding device.

A similar apparatus is also disclosed in Japanese Patent Application Laid-Open No. Hei 6-130633. In the separation apparatus of this publication, the release plate is moved from the film outlet of the cartridge case to the release port of the cartridge case. The rear end of the film that is inserted and engaged with the locking claw in the slit of the spool shaft is removed from the locking claw.

[0016]

The above-mentioned new type of film cartridge has been developed as a type capable of automatically feeding a film, and is used in a state where the leading end of the film slightly protrudes from the patrone as in the prior art. This is not a prerequisite, and the entire length of the film, whether exposed or unexposed at the start of use, is contained in the cartridge. Therefore, it is premised that the leading end of the film is fed by rotating the spool.

However, when designing the above-mentioned intermediate cartridge, a door which can be opened and closed like the film cartridge is provided at the entrance in order to facilitate the insertion of the film, and the spool for winding the film fixes the leading end of the inserted film. It is necessary to easily pull out the terminal at the time of feeding out simply by winding it in, and it is assumed that the terminal at the time of film winding is used with a little length without being wound up Is preferred.

When designing a device for inserting a film cartridge and an intermediate cartridge used under such conditions and rewinding the film into the intermediate cartridge, it is necessary to design the structure and function of the device so as to satisfy the above-mentioned conditions. Of course, it is necessary to consider that the whole device is small, compact, simple, highly efficient, easy to operate, and reliable.

However, in order to obtain a configuration that completely satisfies all the above conditions, it is necessary to consider the following various problems.

It is necessary to have a configuration that can contribute to the achievement.

However, none of the above-mentioned conventional film winding apparatuses and the like discuss the miniaturization, compactness, operability, and the like of the above-mentioned apparatuses, and there is no problem at all. There is a need for a film rewinding device that can completely solve the problem.

The present invention utilizes the movement of a cover plate provided on a case main body of a film rewinding device and an opening and closing plate provided in the case body, taking into account the above-mentioned problems of the conventional film winding device. It is an object of the present invention to provide a film rewinding device that rationalizes a preparation operation by opening and closing a film guide, opening and closing both cartridge doors, and stably holding an intermediate cartridge to reduce the size and size of the device.

[0023]

According to the present invention, as a means for solving the above-mentioned problems, a housing portion for a film cartridge and a winding portion for an intermediate cartridge are disposed at a predetermined distance in a main body case having a cover plate which can be opened and closed.
