Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a camera processor capable of photographing a document on a microfilm and performing various photographic processing steps such as development, fixing, washing, and drying in an integrated manner. The present invention relates to a camera processor in which the film storage method is changed depending on whether the film to be photographed is long or short, so that the above-mentioned steps can be performed consistently.

The definition of long length and short length as used in the present invention is determined by whether the length is larger or smaller than a preset reference length, as described later, and this reference length usually means several meters.

Conventionally, there are two ways to store photographed film in a camera processor: one is to wind the photographically processed film onto a reel in the storage section, and the other is to simply eject it to a discharge hotspot in the storage section without winding it onto a reel. It is being In the former case, a large amount of photographing is carried out at once and a long length of film is continuously processed and wound onto a reel, which facilitates post-processing operations such as storing the processed film as is. However, when the amount of shooting is small, the film becomes short, making it difficult to wind onto a reel, and in addition to increasing the number of times the film must be rewound and the take-up reel attached and detached. If storage is required, the work becomes extremely complicated. In the latter case, since the film is simply discharged to the discharge box, the film can be continuously stored as long as the capacity of the discharge box allows, regardless of the length of the film. However, in this case, especially when a long film is discharged, the film accumulates in the form of a rope, which causes the film to rub against each other and become charged with static electricity or become scratched, resulting in a decline in film quality. The film may become clogged at the film ejection port, making it impossible to eject the film, and to overcome this problem, the film ejection box must be made larger.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a camera processor that eliminates the above-mentioned drawbacks of conventional camera processors and has only the advantages of the above-mentioned two film storage systems.

That is, the present invention includes a camera section for photographing a document or the like, a storage section for storing the film photographed by the camera section, a processor section for subsequently photographically processing the film, and a storage section for storing the film after the photographic processing. In a camera processor equipped with a film storage section, the length of the film photographed by the camera section is compared with a preset film length reference value by a film measuring circuit, and a selection signal is generated as a result of the comparison. operating a switching means near the film storage section to select a film travel path;
When the length of the photographed film is larger than the reference value, the film is wound onto a reel in the film storage section, and when the length of the photographed film is smaller than the reference value, it is stacked in the film storage section. The camera processor is characterized in that the switching means operates to

The details of the present invention will be explained below using examples.

FIG. 1 is a front view of a camera processor according to an embodiment of the present invention, and FIG. 2 is a block diagram of its electric circuit.

In this embodiment, the film 4 photographed by the camera unit 1 is
When the amount of film is larger than a preset reference value, that is, when the film is long, the film measuring circuit 21 issues a signal to switch the film transport path provided near the film entrance of the film ejection box 5. A certain guide switching lever 6 is operated so that the film 4 after photographic processing is wound on the reel 7,
Further, when the amount of photographed film 4 is less than the reference value, that is, when the film is short, the guide switching lever 6 does not operate and the film ejection box 5
This camera processor is equipped with a film ejecting device configured to stack and accumulate film 4 after photographic processing within the camera processor. That is, the present camera processor is broadly divided into a camera section 1, a film storage section 2, a processor section 3, and a film ejection box 5 which is a film storage section. In the camera section 1, a document 14 is photographed on a film 4 supplied from a reel 15 through a lens 16 and the like. The photographed film 4 is transferred to drive rollers 11, 11a and drive rollers 12, 12a in the film storage section 2.
It is wound onto the reel 17 via the . The drive rollers 11, 11a measure the amount of photographed film 4, and input the measured value to a measuring circuit 21 shown in FIG. The measurement circuit 21 does not emit a signal when the input measurement value is less than the reference value preset in the measurement circuit 21 (i.e., it is short), and conversely, when it is greater than the reference value (i.e., (in the case of a long length), it is configured to emit a signal. Note that this reference value is determined by the capacity of the film discharge box 5, etc., and can be freely set by the measuring circuit 21.

When a desired amount of photographing has been achieved, the last end of the photographed film 4 is fed into the film storage section 2 by operating a photographic processing switch (not shown), and the film cutter 13 is operated to cut the film 4. The following explanation assumes that the amount of photographed images is less than the above-mentioned reference value. After the photographed film 4 is cut as described above, the drive rollers 12, 12a
While holding the vicinity of the cut portion of the film 4, the cut portion of the film 4 is rotated 90° from the position A to the position B so that the cut portion of the film 4 corresponds to the entrance of the film guide 19 of the processor section 3. The rollers 12, 12a are configured to return to position A once the photographed film has been fed. Thereafter, the film 4 is fed into the processor section 3 by drive rollers 12, 12a. The fed film 4 is guided through each process of photographic processing by a film guide 19, rollers 18, etc., and then delivered to a film discharge box 5.
sent to. In this case, the guide switching lever 6 is in a position to close the film guide on the take-up reel 7 side, and the film 4 sent to the film ejection box 5 after photo processing is conveyed in the direction of the film delivery rollers 10, 10a. Being done,
The rollers 10 and 10a stack and store the films at the bottom of the film discharge box 5.

In this way, when the exposure amount is less than the reference value, that is, when the film is short, the measuring circuit 21 does not emit a signal, so even if the cutter 13 operates and a signal is emitted from the cutter circuit 22, the AND circuit 23, no further activation signal is issued, and the films are stacked and stored as described above without the guide switching lever 6 being operated from its normal position.

On the other hand, if the amount of shooting is greater than the reference value mentioned above,
The measuring circuit 21 emits a signal, and the signal is input to the AND circuit 23. Furthermore, when the cutter 13 operates, the signal generated by the cutter circuit 22 is
It is input to the AND circuit 23. The AND circuit 23 generates a signal based on these two signals, the timer of the timer circuit 24 is set by the signal, and the signal is input to the flip-flop circuit 26 after the set time. This setting time is set until the leading edge of the film reaches just before the guide switching lever 6 after cutting the film. Further, the reason why the timer is used is to eliminate the inconvenience caused when the previously photographed film is in the film guide 19. The guide switching signal is input only during long length processing, and even if continuous processing is performed, there is little chance that the previous film will be in the processing machine, and if it is, cutting will be prohibited. Alternatively, the guide may be switched by a cut signal without using a timer, or by the detection sensor 20 in front of the switching lever. The guide switching lever 6 opens the film guide 19B on the take-up reel 7 side by energizing a solenoid or the like in response to a signal inputted after the above-mentioned set time, and switches the other film guide 19 on the take-up reel 7 side.
It operates to close A. Also, at the same time as the guide switching lever 6 is operated, the film feed rollers 9, 9a are
Then, the reel 7 starts rotating to take up the film 4. The photographically processed film 4 is conveyed to the film discharge box 5 operating as described above, and is wound onto the reel 7 via the feed rollers 9, 9a and the film winding guide 8.
Thereafter, as winding progresses, when the rear end of the film 4 is detected by the detection sensor 20 provided in front of the guide switching lever 6, the flip-flop circuit A signal generated by the film trailing edge detection circuit 25 is inputted to 26. The signal de-energizes the solenoid, etc., and the guide switching lever 6 switches the film guide 19 on the take-up reel 7 side again.
B is closed, and the film feed rollers 9, 9a and reel 7 also stop rotating.

As described above, when a large number of originals 14 are photographed at once and the film 4 becomes long, this camera processor winds it onto the reel 7 and transfers the photographed film 4.
When the film is short, it is configured to be stacked, so compared to the conventional film storage method of camera processors, damage to the film 4 and film clogging can be minimized, and the capacity of the film ejection box 5 can be reduced. It can be reduced to the minimum necessary. In addition, post-processing work such as storage of swimsuits becomes easier.

Although the present invention has been described above using one embodiment, the present invention is not necessarily limited to the above embodiment.

For example, in the embodiment described above, the guide switching lever 6
Although the film 4 is guided to the winding side or the stacking side depending on the configuration, the film storage section is not limited to this method, and the film storage section may be configured as shown in FIG.

That is, a member having the same function as the guide switching lever 6 described above is used as a film winding lever 8, and this lever 8 is normally left hanging down as shown by the broken line in the figure. Similarly to the signal, when a long film is sent, the lever 8 moves to the position c where the film can be wound as shown by the solid line, the take-up reel 7 starts rotating, and the film is wound. The film 4 fed through the guide 19 in the direction of the arrow is wound up.
If the photographed film 4 is short, the film take-up lever 8 is held in the downwardly hanging position D, and the film 4 is allowed to fall under its own weight as shown in the figure, and then placed in the film ejection box 5. It is to be laminated on the bottom of the Even with this configuration, the same effects as those of the above-mentioned embodiments can be achieved.

The camera processor described above is of a type in which the photographed film 4 is once wound up on the reel 17 of the film storage section 2 and then subjected to photographic processing. A buffer chamber 2a is provided between the camera section 1 and the processor section 3, and photographed film 4 is stored in a loop in the buffer chamber 2a so that photographing and photographic processing can be performed continuously. It can also be used for camera processors.

That is, this camera processor stores the film 4 photographed by the camera section 1 in a loop in the buffer chamber 2a, and sends it to the processor section 3 while adjusting the difference between the photographing speed of the camera section 1 and the processing speed of the processor section 3. When the film 4 is long, it is measured by the drive rollers 11 and 11a, and a signal is input from the measuring circuit 21 to the AND circuit 23, while a detection sensor 28 provided near the entrance of the processor section 3 The leading edge of the film 4 sent from the buffer chamber 2a is detected, and a signal is input from the film leading edge detection circuit 27 to the AND circuit 23.
outputs an output signal, and thereafter operates in the same manner as in the previous embodiment, and the film 4 is wound onto the reel 7. In this case, Katsuta 1
The operation in step 3 may be performed when a desired amount of images are taken.

In addition, if the amount of photographed film is smaller than the reference value, no signal is input from the measuring circuit 21 to the AND circuit 23, so the subsequent devices do not operate and the short film 4
is discharged to the bottom of the film discharge box 5. This embodiment constructed in this way has the same effects as the previous embodiment.
