Description

[Detailed description of the invention] The present invention photographs a manuscript etc. on a microfilm,
The present invention relates to a camera processor that temporarily winds and stores photographed film, and then allows the processor to continue processing such as development.

In recent years, camera processors, which integrate a camera (photographing section) and a processor (film processing section after shooting) and can continue to process film after shooting, have become popular in the office due to their advantages such as instant processing and operability. It has come to be widely used as a means of automation.

Normally, camera processors such as those mentioned above continue to process the film after shooting, so for example, after the operator finishes shooting and sends the film to the processor, there is a need to temporarily suspend the operation. If the power switch is turned off for some reason, the film will remain immersed in the processing liquid in the processor and will stop working.

As a result, developing defects may occur on the film,
In some cases, the film may become clogged in the transport system.

The present invention relates to a camera processor that eliminates the inconvenience caused by operational errors as described above, and more specifically, the present invention relates to a camera processor that eliminates the inconvenience caused by operational errors, and more specifically, a camera section that exposes a film image, a film storage section that winds up and stores the exposed film, and When the power switch is turned on, the camera processor, which is connected to a processor section that allows continuous processing such as development of the fed film, is closed by the development start signal and the power is turned off. The present invention provides a camera processor characterized in that it has a developing processing circuit equipped with a relay that operates the processor section even after the switch is turned off and is opened in response to a film trailing edge detection signal. Conventionally, all you had to do was operate the power switch on the camera side, and even if the shooting operation was stopped, everything other than the shooting section continued to operate until the development of the exposed area of the film was completed, and the development process continued. A camera processor that automatically stops all devices when the process is finished is known from Japanese Patent Publication No. 47-14943, but this camera processor is of a type that consistently performs shooting and processing at the same time. (ie, the processing system is constantly driven) and does not require any development start signal as in the present invention.

Hereinafter, the present invention will be explained with reference to drawings showing one embodiment.

FIG. 1 is a diagram showing an outline of a camera processor for photographing and processing a long film, and FIGS. 2 and 3 are operation circuit diagrams of the camera processor. This camera processor is broadly divided into a camera unit 1, a storage unit 2, and a processor unit 3.

When the power switch S is turned on, power is supplied to the photographing system circuit 31 and the entire apparatus via the developing processing system circuit 30 and the relay RL ₁ .

Here, the photographing system circuit 31 via the relay RL ₁ is connected to circuits related to photographing, such as a drive circuit for the document insertion rollers 6 and 6', a circuit for the illumination lamp 8, and the like. When the power is turned on, the document insertion rollers 6, 6' begin to rotate, and the camera is ready for photographing. When the original 5 is inserted, the film 4 moves in synchronization with the original 5 by an original detection sensor (not shown), and a latent image is formed on the film 4 through the lens 9.

The photographed film 4 is transferred to the film feed roller 1
Storage unit 2 by 0,10',11,11'
It is wound up and stored on a take-up reel 13 inside.

Note that the feed rollers 11 and 11' are as described below.
It is provided so as to be swingable at an angle of approximately 90 degrees in the directions shown by arrows A and B in FIG.

Any amount of images can be taken until the predetermined amount determined by the winding capacity in the storage unit 2 is reached. After the desired amount of images has been taken, pressing the feed button 32 for starting development will cause the image to be taken. The final image on the film 4 is fed to a position beyond the film cutter 17, and the film 4 is cut by the cutter 17. When the operation of the cutter 17 is completed, the film feed rollers 11, 11' move to the position where they communicate with the inlet 38 of the processor unit 3 as indicated by the arrow A in FIG. The image is sent out toward the entrance of the processor unit 3, and then processing such as development is started.
In this embodiment, the development start signal is obtained from the feed button 32, but it is also possible to obtain this signal from the operation end signal of the cutter 17. When the above processing is started, the photographed film 4 fed out from the reel 13 by the rollers 11, 11' is transferred to the developer tank 20 via the film introduction groove 19 by a plurality of guide rollers 18 provided for each tank. , Fixer tank 2
1, a washing accelerator liquid tank 22, a washing tank 23, and a drying chamber 24 equipped with a drying fan 25 and a drying heater 26 before being wound onto a reel 28. When the above-mentioned photographing is completed and the feed button 32 is pressed, the document insertion roller drive circuit 35
In response to the signal, the document insertion rollers 6, 6' stop rotating and photographing operations are prohibited. At the same time, flip-flop circuit 33 is set, contact RL _2-1 of relay RL ₂ in the power supply section is closed, and relay RL _{2 is} also closed.
Contact point RL _2-2 sends an activation signal to the drying room control circuit 36, and the drying fan 25 and drying heater 26, which were stopped during photographing, are activated.

If you turn off the power switch S here, the switch will turn off.
S ₁ and S ₂ open, and contact RL _1-1 of relay RL ₁ opens to perform photographing operations such as the drive circuit for document insertion rollers 6 and 6' and the control circuit for photographing illumination lamp 8 in the photographing system circuit 31. However, the development processing circuit 30, which consists of the winding of the photographed film, the cutter drive circuit, the processor unit drive, the control circuit, etc., is turned on by the signal from the feed button 32 mentioned above. Since relay RL ₂ is closed by contact RL _2-1 , it continues to operate. Then, the film 4 is processed, and the rear end of the film 4 is placed near the exit of the processor unit 3.
Alternatively, when it is detected by the detector 27 installed in the take-up chamber 29, a signal from the film trailing edge detection circuit 37 is applied to the reset input terminal of the flip-flop circuit 33, the contacts of the relay RL ₂ are switched, and the entire power supply is cut off. drooping

Also, if the power switch S is not turned off after pressing the feed button, power is of course supplied to all power sources, but when the rear end of the film is detected by the detector 27, the contact RL _2-2 of the relay RL ₂ As a result, the power supply to the drying heater 26, drying fan 25, and other processor units 3 is cut off and turned off. At this time, an alarm display such as a buzzer may be output at the same time to notify the end of the development process.

In this case, whether or not the next shooting can be started is determined by checking the sensor 16 provided in the storage unit 2 on the reel 13.
The structure is such that the document insertion rollers 6, 6' can be driven by the passage of the trailing edge of the film wound up on the film. 56-146109, same 56-
146106, 56-146105, etc., if the configuration is such that the next photograph can be taken even during the developing process, the next photograph can be restarted in a short time after the photograph is completed, which is even more convenient.

Furthermore, the above-mentioned camera processor is used for long film, which winds and stores photographed film on a reel; however, it is not limited to this method; it can also be used for camera processors that cut the film into short lengths and take photographs. In this case, it is sufficient to provide a guide member for feeding the short film to a position corresponding to the storage unit of the above-described embodiment, and the structure can be similar to that of the above-described embodiment.

The present invention has been explained above using one embodiment, but
With this configuration, when the feed button is operated, the operation signal can automatically continue the operation of at least the processor unit of the camera processor regardless of whether the power switch is turned on or off, so that it is possible to automatically continue the operation of at least the processor unit of the camera processor. This not only eliminates film finishing defects, but also eliminates film clogging. Furthermore, if the power switch is turned off without operating the feed button, all operations of the camera processor are stopped while the photographed film is stored in the storage chamber, which is very convenient.
