Description

Description: FIELD OF THE INVENTION The present invention relates to a photosensitive material processing apparatus for a laser typesetting machine.

2. Description of the Related Art An example of a laser typesetting machine will be described below as an example of a conventional photosensitive material processing apparatus. The unsensitized sheet-shaped photosensitive material stored in a rolled state inside the laser typesetting machine body is pulled out by the photosensitive material feeding device and is attached to the upper part of the main body via the laser light irradiation part. It is inserted in the magazine for use and wound up by the rollers in the magazine. One typesetting operation (printing on the photosensitive material with laser light)
At the end of the step, the photosensitive material is cut in the vicinity of the photosensitive material insertion opening of the magazine, and the indicator lamp of the end of photosetting lights up.

Then, during the typesetting operation, the length of the photosensitive material used is recorded by the photosensitive material feed amount recording device provided inside and is displayed to the user. Then, when the next typesetting operation is performed, the newly used data is added to the data recorded in the photosensitive material feed amount recording device until then and displayed. However, if the photosensitive material feed amount recording device is reset before the typesetting operation, only the length of the newly used photosensitive material is recorded and displayed.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above-described configuration, when a plurality of types of photosensitive materials having different properties and different widths of the photoconductors are used while being replaced with each other in one processing apparatus main body In order to manage the remaining amount of each photosensitive material, it is necessary to manually enter the amount of the photosensitive material displayed on the ledger every typesetting operation according to its type. The judgment of the replacement timing of the photosensitive material requires the user to add the data recorded during each typesetting operation to obtain the total usage amount, which is very inconvenient. The present invention has been made in view of the above problems, and when a plurality of types of photosensitive materials having different properties are used while being replaced by one processing apparatus main body, the replacement time can be easily set for each photosensitive material. It is an object of the present invention to provide a photosensitive material processing device capable of making a judgment.

Means for Solving the Problems In order to solve the above problems, the present invention has a detecting means for detecting the type of the photosensitive material mounted and an area for recording the usage amounts of a plurality of photosensitive materials respectively. Memory is provided,
An area corresponding to the type of the photosensitive material output from the detecting means is selected from the memory, and the data in the area is updated based on a signal from the photosensitive material feed amount detecting means.

Operation With the above-mentioned configuration, when using multiple types of photosensitive materials with different properties and widths while exchanging them in one processing unit main body, the user can change the information recorded in each area of the memory. Based on this, the remaining amount of each photosensitive material can be managed individually, and the replacement timing of each photosensitive material can be individually determined.

Example Hereinafter, an example of a laser typesetting machine will be described as an example of the photosensitive material processing apparatus according to the present invention.

In FIG. 1, 1 is a photographic paper, a film-like photosensitive recording medium such as a silver salt film (hereinafter referred to as a photosensitive material), 2 is a photosensitive material 1
And a photosensitive material box configured to block light from the outside. The photosensitive material 1 is wound and stored in a photosensitive material box 2 in a roll shape. By the way, several kinds of photosensitive materials having different widths are prepared as the photosensitive materials used in the laser typesetting machine, and they are housed in photosensitive material boxes having different widths. Then, before carrying out the photosetting operation, a photosensitive material having an appropriate width is selected and used as necessary. Reference numeral 3 is a photosensitive material feeding motor, and 4 is a photosensitive material feeding roller connected to the motor 3. Reference numeral 5 is a roller arranged so as to face the roller 4, and the photosensitive material 1 is sandwiched between the roller 4 and the roller 5. 6 is roller 5
It is an encoder that detects the rotation of the. The roller 5 rotates simultaneously with the feeding of the photosensitive material 1, and the encoder 6 outputs a number of pulses corresponding to the feeding amount of the photosensitive material 1.

Reference numeral 7 is a counter for counting the pulses output from the encoder 6. Reference numeral 8 is a photosensitive material type detection circuit. In this embodiment, several kinds of photosensitive materials having different widths are used, and in this case, the width of the photosensitive material box also varies depending on the width of the photosensitive material as described above. The laser typesetting machine according to the present embodiment is provided with two slide plates for fixing the photosensitive material boxes having different widths as described above, and the slide plates are slid to move the photosensitive material boxes from the lateral direction. It is designed to be sandwiched and fixed by both slide plates. If the size of the photosensitive material box is different, this
The distance between the two slide plates sandwiched therebetween varies depending on the size of the photosensitive material box. The photosensitive material type detection circuit 8 is configured to detect the type of photosensitive material from the distance between two slide plates. Reference numeral 9 is a storage circuit for storing the count value of the counter 7, 10 is a control circuit for controlling each section, and 11 is an indicator for displaying the remaining amount of various photosensitive materials.

Next, a detailed description will be given with reference to FIG. The data output from the counter 7 is added to the storage waterway 9 via the data bus line. The data stored in the memory circuit 9 is added to the control circuit 10 via the data bus line.
The memory circuit 9 is divided into a plurality of memory areas in order to accommodate a plurality of types of photosensitive materials, and the output data from the counter 7 is stored in the memory corresponding to the address signal from the control circuit.

Next, the operation will be described.

First, when the photosensitive material box 2 is mounted on the main body, the photosensitive material type detection circuit 8 determines the type of the mounted photosensitive material and sends the information to the control circuit 10. Then, the control circuit 10 sends an address signal corresponding to the mounted photosensitive material to the storage circuit 9 based on the information and sends a data read command signal to the counter 7. Then, the data already stored in the designated memory, for example, in the memory corresponding to the photosensitive material a, for example, when the photosensitive material a is already used for 5 m, the data corresponding to 5 m is transferred via the bus line. It is read by the counter 7. However, when the mounted photosensitive material is completely unused, the user issues a reset command to set data corresponding to unused photosensitive material, that is, data corresponding to 0 m, in the counter 7. .

Next, when the photosetting operation is started, the value in the counter 7 is successively added as the photosensitive material is fed, and for example, the photosensitive material a
When 10 m is used, the data in the counter 7 corresponds to 15 m. However, if the reset command is input before the operation, the data will correspond to the amount used thereafter, that is, 10 m. When the typesetting operation is completed, the control circuit 10 sends a data output command signal to the counter 7, and also sends a data read command signal to the memory circuit 9 to cause the memory circuit 9 to read the output data from the counter 7, The data in a predetermined memory in the memory circuit 9, that is, the memory corresponding to the photosensitive material a is updated. Further, the control circuit 10 reads the data from the counter 7 output to the data bus line, and based on the data, displays the total amount of the photosensitive material used at that time using the display 11. The user can know the total amount of the photosensitive material used at that time based on the displayed information every time the photosetting operation is performed.
By comparing the total amount given in advance, it is possible to determine the replacement time of the photosensitive material. Incidentally, as a photosensitive material used in this type of laser typesetting machine, there are many cases in which 30 m of the photosensitive material is stored in a photosensitive material box. If only the length of 30 m is used even if the width is different, the data read from the counter 7 in the control circuit 10 is subtracted from the data corresponding to the 30 m to obtain the obtained data. Based on this, the remaining amount of the photosensitive material may be displayed.

Next, a second embodiment of the present invention will be described.

In FIG. 3, a pulse signal from the photosensitive material feed amount detector is directly input to the controller 12. Then, during the typesetting operation, the control device 12 directly adds 1 to the data in the memory in the selected storage device 9 each time the pulse signal is input. Further, during the photosetting operation, data indicating the usage amount of the photosensitive material is stored in the register for addition in the control device, and the amount of the photosensitive material used based on the data is displayed during the photosetting operation. be able to.

In the above embodiment, the photosensitive material feed amount detecting unit is the encoder 6 connected to the roller 5 as shown in FIG.
Although the feeding amount of the photosensitive material is detected by the method, another method shown in FIGS. 4, 5, and 6 may be used. In the example of FIG. 4, the detection roller 13 and the auxiliary roller 14 other than the photosensitive material feeding roller are provided.
The encoder 6 is connected to. In the example of FIG. 5, an encoder 6 is connected to the rotary shaft of the photosensitive material feeding motor 3. Further, in the example of FIG. 6, a feed hole is provided on the side of the photosensitive material 1.
15 are provided. Then, the light emitting element 16 and the light receiving element 17 are provided so as to sandwich the portion, and the pulse voltage generated in the light receiving element 17 is taken out by moving the photosensitive material 1.
