Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photosensitive material conveying device for conveying a photosensitive material from an image printing device to a processing device in a light-shielded state.

[0002]

2. Description of the Related Art For example, a scanner for converting a photographic image into a halftone image for printing by using an original as a document scans a laser beam which is modulated according to an image signal read from the photographic image and converted into an electric signal. Then, the photosensitive material is exposed. As a result, the light-sensitive material irradiated with the laser light is exposed according to the photographic image and a halftone image is recorded. The exposed photosensitive material is then subjected to a developing process.

In recent years, various attempts have been made to improve the processing capacity by combining an image printing apparatus such as a scanner and an automatic developing machine which is a photosensitive material processing apparatus for developing a photosensitive material exposed by the image printing apparatus. Has been implemented. In this case, since the image-printing apparatus such as a scanner and the automatic developing machine are different in the conveying speed and the conveying port height of the photosensitive material, there are differences in the conveying speed between the scanner and the automatic developing machine, discharge, and the insertion port. In general, a photosensitive material conveying device that eliminates the positional deviation is interposed.

This photosensitive material conveying device is provided with a conveying path for conveying the photosensitive material at a predetermined speed by a driving force of a driving source, and the conveying path is shielded so that light from the outside does not reach the photosensitive material. In addition, guides are provided so as to protrude from each other so that the photosensitive material can be reliably delivered to the next apparatus, and the transport path is provided so as to be substantially continuous between the discharge port of the scanner and the automatic developing machine. In addition, when the photosensitive material is conveyed together with the scanner, the conveying speed is controlled so as to match the conveying speed on the scanner side, and when the photosensitive material is conveyed together with the automatic developing machine, the conveying speed is controlled so as to coincide with the conveying speed of the automatic developing machine. Is becoming

The photosensitive material transporting device thus provided allows the photosensitive material discharged from the scanner to be sent to the automatic developing machine. As a result, the photosensitive material is continuously developed by an automatic developing machine when a predetermined image is exposed by the image output device.

By the way, in this photosensitive material conveying device, a conveying path for the photosensitive material is formed by a plurality of roller pairs and a plurality of guides arranged between these roller pairs. The photosensitive material nipped and fed from the roller pair is guided to the downstream roller by a guide. In addition, the photosensitive material conveying device can discharge the photosensitive material outward from the middle portion of the conveying path. It can be pulled out from the machine and processed by another automatic processor.

[0007]

However, in such a photosensitive material conveying device, when the photosensitive material is retracted from the middle of the conveying path and pulled out, the nipping of the photosensitive material by the roller pair is released and the guide is further moved. However, the work is complicated because each of these work is performed individually.

In view of the above facts, the present invention is a simple work,
An object of the present invention is to provide a photosensitive material conveying device that can retract a photosensitive material from a normal conveying path.

[0009]

SUMMARY OF THE INVENTION A photosensitive material conveying apparatus according to the present invention has a first conveying path for conveying a photosensitive material sent from one apparatus while sandwiching it between a pair of rollers and sending the photosensitive material to the other apparatus by a guide. A photosensitive material transporting device having a second transport path for taking out a photosensitive material delivered from the one device, wherein the photosensitive material delivered from the one device is guided to the first or second transport route. A path changing mechanism section for moving and switching the guide as described above, and a pinching release mechanism for interlocking with the path changing mechanism section and for releasing the nipping of the photosensitive material by the roller pair when switched to the second transport path. And a part.

[0010]

In the photosensitive material conveying apparatus of the present invention having the above structure, the pair of rollers and the guide form a conveying path for the photosensitive material. This transport path is divided into the first and the second by the path changing mechanism section.
Is switched to the transport path. Further, the pair of rollers is switched between the state in which the photosensitive material can be sandwiched and the state in which the photosensitive material is not sandwiched by the sandwiching release mechanism section.

The pinching release mechanism section and the path changing section operate in conjunction with each other, and when the second transport path is selected, the roller pair does not pinch the photosensitive material. Thus, when the photosensitive material is taken out, it is possible to select the conveying path and release the nipping of the roller pair by one operation.

For example, when the guide path is swung to select the transport path and one roller is swung to release the pinching of the roller pair, it is easy to use a cam connected to the same rotary shaft. Can be done.

It is constituted by a movable guide plate 130 arranged above. The movable guide plate 130 is rotatably supported on the downstream side by the side plate 80, and on the upstream side, the cam 108 of the eccentric roller 100 is further protruded in the width direction of the transport path and has a tip portion.
A leg portion 132 extending toward is formed.

Therefore, at the upstream end of the movable guide plate 130, these legs 132 are supported by contacting the cam 108. The cam 108 rotates with the rotation of the dial 116, and the movable guide plate 130 is swung in the contacting and separating direction with the fixed guide plate 128 with the rotation of the cam 108. The swinging of the movable guide plate 130 in the contacting / separating direction is separated from the fixed guide plate 128 when the pair of rollers 82 can hold the photosensitive material 14 by the dial 116, and the photosensitive member sent out from the pair of rollers 82 is moved. The material 14 is inserted between the movable guide plate 130 and the fixed guide plate 128 and guided to the roller pair 84.

When the roller pair 82 is separated,
The movable guide plate 130 approaches the fixed guide plate 128, and the step portion 1 formed at the upstream end of the fixed guide plate 128.
It is accommodated in 34. Therefore, the photosensitive material 14 inserted between the roller pair 82 is guided to the upper surface of the movable guide plate 130.

An auxiliary guide plate 136 is erected upward at an intermediate portion of the movable guide plate 130 in the carrying direction. As shown in FIGS. 2 and 3, the casing 78 is provided with an opening / closing lid 138 on the upper surface. The photosensitive material 14 guided to the upper surface of the movable guide plate 130 is guided to the opening / closing lid 138 by the auxiliary guide plate 136.
Therefore, by opening the opening / closing lid 138, the operator can take out the photosensitive material 14 guided by the auxiliary guide plate 136.

As shown in FIGS. 3 and 4, the insertion port 140 is provided in the casing 78 of the transport unit 44.
A shutter 142 that opens and closes the insertion port 140 is provided in the vicinity of the insertion port 140. Normally, this shutter 142 is closed, and the gas of the processing liquid accumulated in the processing liquid processing unit 32 of the automatic processor 16 is inserted into the insertion port 140. The scanner 12 does not enter the scanner 12.

As shown in FIG. 3, a guide group 144 is disposed near the roller pair 84, and the photosensitive material 14 can be inserted from the opening / closing lid 138 toward the automatic developing machine 16.

As shown in FIG. 5, the fixed guide plate 1
A motor 146 serving as a drive source of the transport unit 44 is disposed below the 28. A sprocket 148 is arranged on a rotating shaft 146A of the motor 146, and a driving force is transmitted to the roller pair 82, 84 by a chain 150.

The control section 46 arranged below the transport unit 44 mainly controls the driving of the motor 146. The control unit 46 is connected to the scanner 12 and detects the operation of the scanner 12. When the operation of the scanner 12 is detected, the motor 146 causes the roller pairs 82 and 84 to move to the conveyance speed of the scanner 12. It is designed to drive at approximately the same speed.

The control unit 46 is also connected to the automatic developing machine 16, and when the automatic developing machine 16 detects the insertion of the photosensitive material 14, changes the driving speed of the motor 146,
The roller pairs 82 and 84 are driven according to the conveying speed of the automatic developing machine 16.

The control section 46 includes a movable guide plate 13
A limit switch (not shown) for detecting the position of 0 is connected, and the roller pair 82 depends on the position of the movable guide plate 130.
It is detected whether or not the photosensitive material 14 can be nipped. Further, the control unit 46 includes an interlock mechanism that prevents the motor 146 from being driven when the opening / closing lid 138 or the upper surface of the casing 78 is open, and the shutter 142.
Does not operate the motor 146 when the insertion opening 140 is closed.

Next, the operation of this embodiment will be described. In the photographic image processing system 10 shown in FIG. 1, the scanner 12 exposes a halftone image by irradiating the photosensitive material 14 with laser light according to an image signal. The exposed photosensitive material 14 is transferred from the scanner 12 to the transfer device 3 by driving the transfer roller pair 24.
0 is sent to the guide unit 42. Guidance unit 4
In 2, the guides 48 and 50 guide the photosensitive material 14 sent by the pair of transport rollers 24 of the scanner 12 toward the transport unit 44.

In the transport unit 44 shown in FIG. 3, the motor 146 is driven by the operation signal of the scanner 12 so that the photosensitive material 14 can be transported at substantially the same speed as the transport roller pair 24 of the scanner 12. When the photosensitive material 14 is inserted from the guide unit 44 in this state, the photosensitive material 14 is nipped by the roller pair 82 and is conveyed in the guide portion 86. As a result, the photosensitive material 14 is transferred from the scanner 12 to the transport unit 44.

The photosensitive material 14 is further transported by the transport unit 44 and sent to the automatic developing machine 16. In the automatic processor 16, when the insertion sensor 40 detects that the tip of the photosensitive material 14 has been inserted, the processing liquid processing unit 32 and the drying unit 34 are operated. At the same time, the automatic developing machine 16 informs the control unit 46 of the carrying device 30 that the photosensitive material 14 has been inserted. As a result, the control unit 46 causes the motor 146 to
By changing the driving speed of the roller pair 82, 84 to match the conveying speed of the photosensitive material 14 of the automatic developing machine 16.

When the photosensitive material 14 is fed from the transport unit 44, the automatic developing machine 16 shown in FIG. 1 carries out the processing liquid treatment by successively immersing the photosensitive material 14 in a developing solution, a fixing solution and washing water while transporting the photosensitive material 14. After that, the drying unit 34 performs a drying process and discharges. That is, the photographic image processing system 10
Then, when the halftone image corresponding to the image signal is exposed by the scanner 12, the exposed photosensitive material 14 is continuously developed and finished by the automatic developing machine 16.

In this photographic image processing system 10,
The photosensitive material 14 exposed by the scanner 12 is automatically processed by the automatic developing machine 1.
When it is pulled out before being sent to 6, the transport unit 44 is used.

As shown in FIGS. 5 and 6, in the transport unit 44, the dial 116 provided outside the casing 78 is pulled to move the engagement pin 120 to the dial engagement portion 1.
The dial 1 is pulled out from the 18 engaging holes 122.
16 becomes rotatable. The dial 116 is rotated 180 degrees and the engagement pin 120 is inserted into the other engagement hole 122. The rotation of the dial 116 rotates the eccentric roller 100 and the cam 108.

When the eccentric roller 100 rotates 180 degrees, the lever 102 swings to lower the roller 94 of the roller pair 82. As a result, the roller 92 and the roller 94 of the roller pair 82 are separated from each other. Also, the leg portion 13 supported by contacting the cam 108 by the rotation of the cam 108
In both cases, the movable guide plate 130 moves, and the movable guide plate 130 approaches the fixed guide plate 128 and is housed in the step portion 134.

As a result, in the carrying unit 44, the photosensitive material 14 is not carried by being nipped by the roller pair 82. By the movement of the movable guide plate 130,
A limit switch (not shown) switches the contacts to stop driving the motor 146.

In addition, the photosensitive material 14 in the transport unit 44
Since the movable guide plate 130 is housed in the stepped portion 134, the transport path can be changed in the direction along the upper surface of the movable guide plate 130 and the auxiliary guide plate 136.

Therefore, the photosensitive material 14 sent from the scanner 12 into the transport unit 44 by driving the transport roller pair 24 passes between the roller 92 and the roller 94 of the roller pair 82, and the movable guide plate 130. Guided from the upper surface along the auxiliary guide 36, the rear end of the photosensitive material 14 stops in a state where the rear end of the photosensitive material 14 is separated from the transport roller pair 24 of the scanner 12.
In this state, the transport unit 44 shown in FIG. 2 and FIG.
The photosensitive material 14 can be extracted by opening the opening / closing lid 138.

In the carrying unit 44, since the dial 116 is rotated to separate the roller 92 and the roller 94 of the roller pair 82, the photosensitive material 14 can be extracted without resistance.

When the transport unit 44 is returned to the normal use state, the dial 116 is further rotated 180 degrees to rotate the eccentric roller 100. As a result, the roller 92 and the roller 94 of the roller pair 82 are brought close to each other so that the photosensitive material 14 can be nipped, and the cam 108 rotates to separate the movable guide plate 130 from the fixed guide plate 128. As a result, a conveyance path between the roller pair 82 and the roller pair 84 is secured, and the photosensitive material 14 nipped and conveyed by the roller pair 82 is guided to the roller pair 84.

As described above, the carrier device 30 according to the present embodiment.
The photosensitive material 14 can be easily rotated by rotating the dial 116.
The transport path of the casing can be changed, and the casing 78
There is no need to look into the inside of the work.

In this embodiment, the example in which the scanner 12 is applied as the image printing apparatus has been described, but the image printing apparatus is not limited to this. For example, it is possible to apply an image of a newspaper facsimile or the like by scanning or surface-exposing an image on a light-sensitive material, and when the light-sensitive material is exposed and subsequently subjected to development processing.

As described above, the photosensitive material conveying apparatus according to the present invention includes the path changing mechanism section for changing the conveying path of the photosensitive material and the nipping release mechanism section for changing the nipping state of the photosensitive material by the roller pair. Are linked.

As a result, the excellent effect that the photosensitive material can be easily taken out by one operation can be obtained.
