Abstract

PURPOSE:To detect film jamming and to prevent a film from being damaged by exposing the leading edge of the film after being cut near a cutter and detecting the leading edge of the film in the transfer path of a developing device. CONSTITUTION:The film F already photographed is temporary stored in a buffer chamber 6, and the film F which is stored is cut by the cutter 7 at a position behind the backmost part of the film already photographed in the case of development processing and transferred to the developing part B. At such a time, a light emitting member 9 is allowed to emit light immediately after the cutter 7 is actuated and before next developing is started. Thus, the leading edge of the film F to which next developing should be performed is exposed and it can be detected by non-contact type optical sensors 16-19 after it passes a developer tank 11. Therefore, whether or not film jamming occurs is discriminated without damaging the film based on whether or not the leading edge of the film F passes the respective paths between the sensors 15 and 16, 16 and 17, 17 and 18, 18 and 19 in a fixed time.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a processor camera that photographs a subject image on a film and develops the film.

<Conventional technology> Conventionally, this type of processor camera has, for example, a third processor camera.
There is a processor camera as shown in the figure.

That is, this processor camera has a photographing section A and a photographing section B.
It is configured to sequentially transport the unphotographed film F loaded in the film supply chamber 1 to the photographing section A and the developing section B.

In the photographing section A, the sheet-like object S is fed from the paper feed table 2 to the recording section 3 inside the stomach, and an image of the sheet-like object S is photographed while the sheet-like object S passes through the recording section 3. Through the lens 4, the film E transported from the supply reel 5 is subjected to slit exposure and an image is photographed and recorded, and the photographed film F is stored in the buffer chamber 6 until -1.
During development, the stored film F is cut by a cutter 7 at the rearmost position of the photographed film and transported to the development section. On the other hand, the sheet-like object S that has been recorded in the recording section 3 is discharged to the stacker 8.

Further, the photographed film F transferred from the photographing section A is placed in the developer tank 11. Fixed @ tank 12. After passing through a washing tank 13 and being developed, it is dried with hot air and wound onto a take-up reel 14 as a finished film.

<Problem to be solved by the invention> However, in the conventional processor camera described above, the developing section B
It is common practice to detect film jams at

Specifically, the time from the start of the development process is managed using a timer or the like, and film jams are detected based on whether the leading edge of the finished film passes through a certain bus within a certain period of time. The leading edge of the finished film was detected using a contact sensor (switch) such as a microswitch.

However, in this case, the film and sensor must come into contact, which can result in scratches on the film and missing images.
It also had drawbacks such as film jams occurring in the sensor section. If the leading edge of the film could be detected using a non-contact optical sensor or the like, this drawback would be overcome, but after passing through the developer tank 11, the film F becomes colorless and transparent except for the exposed part, and furthermore, the leading edge of the film has Since photography is usually not performed in consideration of editing, etc., it is difficult for these sensors to detect the leading edge of the film.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a processor camera which eliminates the drawbacks of the prior art and which can reliably detect film jams without damaging the film.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention includes a photographing section that photographs a subject on film, a developing section that develops the photographed film, and a film transfer section from the photographing section to the developing section. In a processor camera, the processor camera has a conveyance means for sending out the photographed film, and a cutter for cutting the photographed film after conveying it to the developing section, and an exposure means for exposing the leading edge of the film after cutting is provided near the cutter. At the same time, a non-contact type sensor for detecting the leading edge of the film is provided in the transport path of the developing section.

<Function> The processor camera with the above configuration uses an exposure means to form an exposed area at the leading edge of the film cut by the cutter, and detects the exposed area at the leading edge of the film with a non-contact sensor in the developing unit, thereby preventing film jams. can be easily detected, and the film can be prevented from being damaged by the sensor.

<Example> An embodiment of the present invention will be described below with reference to FIG.

Note that the same parts as those of the conventional example shown in FIG. 3 are given the same reference numerals, and explanations of the structures thereof will be omitted, and only the different structures will be explained.

In the processor camera shown in FIG. 1, reference numeral 9 denotes a light emitting member provided near the upstream side of the pharynx of the cutter 7. The leading edge of the film F is exposed by emitting light before starting I.

Reference numerals 15, 16, 17, 18, and 19 are non-contact optical sensors for detecting the leading edge of the film F, and they are located on the inlet side of the developing tank 11, the output side of the developing tank 11, and the fixing tank 12 in the transfer path in the developing section B, respectively. It is provided on the outlet side of the washing tank 13 and on the upstream side of the take-up reel 14. The other configurations are the same as those of the conventional example described above.

The operation of this embodiment having the above configuration will be explained.

The photographed film F is stored in the -H buffer chamber 6, and during development processing, the stored film F is cut by a cutter 7 at the rearmost position of the photographed film and transferred to the developing section B. However, at this time, the light-emitting member 9 is caused to emit light immediately after the cutter 7 is operated or before the next development is started. As a result, the leading edge of the next film F to be developed is exposed, and even after the exposed portion passes through the developer tank 11 of the developing section B, the leading edge of the film does not become colorless and transparent and can be detected by the sensors 16 to 19. Become. Therefore, whether or not the leading edge of the film F passes through the sensors 15, 16, 16, 17, 17, and 18, 18 and one inter-sensor bus within a certain period of time determines whether there is a film jam or not without damaging the film. It is determined.

A single reference numeral will be given to each, and only the different points will be explained.

In this embodiment, as a means for exposing the leading edge of the film after cutting,
A slit 21 is provided in the body of the photographing section A at an upstream position of the cutter 7, and a shutter 22 is provided on the inner surface of the slit 21.
It has been established. The other configurations are the same as those of the previous embodiment.

In this embodiment having the above configuration, by opening and closing the shutter 22 at the leading end of the film F after cutting, an exposed portion can be formed using external light from the slit 21.

<Effects of the Invention> As explained above, the present invention provides an exposure means in the vicinity of the cutter that cuts the photographed film, exposes the leading edge of the cut film, and places the exposed portion in the transport path of the developing section. By detecting the leading edge of the film using a non-contact sensor, it is possible to detect film jams in the developing section.
This has the effect of not damaging the film, and especially preventing jamming at the sensor section.
