In the above configuration, in the present embodiment,
As shown in FIGS. 2 to 7, an exposure case 26 in which an exposure head 25 is assembled is mounted on a frame 11 of the machine body 1, and an exposure position transport unit 6 is mounted on the frame 11. The frame 11 is made of an aluminum casting, and can absorb vibrations generated in the exposure position transport unit 6 and the exposure device 23 by the aluminum casting.

The exposure position transport unit 6 can be moved horizontally between a transport position close to the exposure head 25 shown in FIG. 2 and a retracted position separated from the exposure head 25 shown in FIG.

Specifically, as shown in FIGS. 2 to 4,
The frame 11 includes a support surface 12 on which the exposure position transport unit 6 is placed, side walls 12 and 13 extending upward from an end of one side of the support surface 12, and outward from an upper end of the side wall 13.

6 are protruded from the bottom surface of the four fitting portions 6.
The exposure position transport unit 6 is supported on the installation plate 66 of the frame 11 by fitting the 7 to the guide rail portion 15.

Then, by pulling the exposure position transport unit 6 leftward in FIG. 2 from the state shown in FIG. 2, the exposure position transport unit 6 is separated from the exposure head 25 along the guide rails 15, 15. To move from the transport position close to the exposure head 25 shown in FIG. 2 to the retreat position separated from the exposure head 25 shown in FIG.

By pushing the exposure position transport unit 6 in the state shown in FIG. 3 toward the exposure head 25, the exposure position transfer unit 6 is moved from the retracted position separated from the exposure head 25 shown in FIG. Can be moved to a transport position close to the transfer position.

In moving the exposure position transport unit 6 between the transport position and the retreat position, the exposure position transport unit 6 may be moved manually, or mechanically driven by a motor under the control of the controller 5. The exposure position transport unit 6 may be moved first.

Further, between the exposure position transfer unit 6 and the frame 11, as shown in FIGS. 2 to 7, the exposure position transfer unit 6 is positioned at a predetermined transfer position (positioning with respect to the line exposure head 25). And fixing means 7 for fixing. As shown in FIGS. 2 to 5, the fixing means 7 includes two positioning pins 71 projecting toward the exposure head 25 from a member 61a supporting the pressing roller 42 in the exposure position transport unit 6, and FIG. 2 to 5
As shown in FIG. 7, the exposure position transport unit 6 is fixed to the frame 11 with the contact surface 72 provided on the exposure case 26 and contacting the positioning pin 71 and the contact surface 72 pressed by the positioning pin 71. And a fixed arm 73.

When the tip of the positioning pin 71 comes into contact with the contact surface 72 of the exposure case 26, the exposure position transport unit 6 includes the first pair of exposure rollers 4a and the second pair of exposure rollers 4b. The transport surface to be exposed is the exposure head 25
And the exposure surface (focus surface) to be exposed.

After the tip of the positioning pin 71 is brought into contact with the contact surface 72 to position the exposure position transport unit 6 with respect to the exposure head 25, the exposure head 25
It is necessary to fix the exposure position transport unit 6 to the frame 11 at a predetermined transport position in order to prevent the distance between the exposure position transport unit 6 and the exposure position transport unit 6 from fluctuating.

Therefore, in the present embodiment, when the tip of the positioning pin 71 comes into contact with the contact surface 72, the exposure position transport unit 6 moves the frame 11 with the positioning pin 71 pressed against the contact surface 72. The exposure position transport unit 6 is fixed to the frame 11 by using the fixed arm 73 so as to be fixed to the predetermined position.

Specifically, the fixed arm 73 is fixed to a shaft 74 as shown in FIGS.
The shaft 74 is rotatably supported by a shaft case 75. A worm gear 76 is attached to one end of the shaft 74, and the torque of an arm drive motor 77 for driving the shaft 74 is rotated by a torque limiter 78, a coupling 79, The power is transmitted to the shaft 74 via a worm gear 80 fixed to the shaft of the coupling 79.

Further, a torsion spring 8 is attached to the shaft 74.
1 is fixedly inserted, and one end of the torsion spring 81 is fixed to the fixed arm 73 and the other end is fixed to the shaft case 75, so that the fixed arm 73 is rotated in one direction (the direction in which the fixed arm 73 is pressed against the frame 11). I try to urge toward.

The arm driving motor 77 is rotatable in the normal and reverse directions. When the fixed arm 73 is driven in a direction for releasing the fixing, the arm driving motor 77 is moved in a direction opposite to the urging force of the torsion spring 81. By rotating and rotating the shaft 74, the fixed arm 73 is swung to a fixed release position (the position indicated by the phantom line in FIG. 7), and the fixed arm 73 is separated from the frame 11 and the frame of the exposure position transport unit 6 is moved. 11 is released.

When the fixed arm 73 is driven from the unlocked position to the fixed position, the arm driving motor 7
By rotating the shaft 74 by rotating the shaft 7 in the biasing direction of the torsion spring 81, the fixed arm 73 swings to a fixed position (the position indicated by the solid line in FIG. 7), and the fixed arm 73 contacts the frame 11. The exposure position transport unit 6 is fixed to the frame 11.

When the fixed arm 73 is moved from the unlocked position to the fixed position, the arm driving motor 7
7 is overrun for about 2 seconds and the frame 11 is pressed by the fixed arm 73 so that the exposure position transport unit 6 is always kept pressed against the exposure head 25 side.

More specifically, after the exposure position transport unit 6 is forcibly moved from the retracted position to the transport position, and the exposure position transport unit 6 reaches the predetermined transport position by the positioning pins 71, the fixed arm 73 is moved to the frame 11 position. The controller 5 drives the arm driving motor 77 for a certain period of time (for example, about 2 seconds) to swing to the supporting position.
Drive control.

With this overrun control, when the arm driving motor 77 is stopped, the exposure position transport unit 6 is kept pressed with the fixed arm 73 pressed against the frame 11 at all times.
Can be stopped, so that the fixed arm 73 is
By pressing the positioning pin 71 against the exposure case 26, the exposure position transport unit 6 is securely supported at a predetermined transport position of the frame 11 without shaking even if some external vibration is input to the exposure position transport unit 6. Is done.

When the fixed arm 73 comes into contact with the frame 11 while the arm driving motor 77 is rotating, the torque limiter 78 controls the arm driving motor 7.
Only 7 is rotated.

As shown in FIGS. 6 and 7, two position sensors 82 are provided for detecting the fixed position of the fixed arm 73 to the frame 11 and the fixed release position. Only the position sensor is shown), a rectangular detection plate 83 is fixed to the end of the shaft 74 that swings the fixed arm 73 on the opposite side to the mounting position of the worm gear 76, and the detection plate 83 is When the detection plate 83 rotates with the rotation of the shaft 74, the position of the detection plate 83 at that time is detected, thereby detecting the fixed arm 73.
Is detected at a fixed position or at a fixed release position.

The detection result of the detection plate 83 by the position sensor 82 is input to the controller 5, and when the exposure position transport unit 6 is moved to the retreat position, the exposure position transport unit 6 is moved to the retreat position by an output from the controller 5. For example, it is displayed on the monitor 21 whether or not the exposure position transport unit 6 can be moved, or the exposure position transport unit 6 is locked so as not to be moved to the retreat position.

Next, the operation for moving the exposure position transfer unit 6 from the transfer position to the retreat position and the case for moving the exposure position transfer unit 6 from the retreat position to the transfer position in this embodiment will be described.

If a paper jam occurs in the exposure position transport unit 6 during the operation of the photographic processing apparatus, the paper jam is detected by a separately provided sensor (not shown) for detecting the paper jam. A command to be input to the controller 5 and release the fixed arm 73 fixed to the frame 11 is output from the controller 5 to the arm driving motor 77.

Then, the output of the controller 5 causes the arm driving motor 77 to rotate in the direction for releasing the fixed arm 73, and the fixed arm 73 is separated from the frame 11 and shown in the phantom line shown in FIG. Rocks to the position.

When the fixing of the fixed arm 73 to the frame 11 is released, the operator pulls out the exposure position transfer unit 6 from the transfer position shown in FIG. 2 to the retracted position shown in FIG. Then, when returning the exposure position transport unit 6 to the transport position, the operator moves the exposure position transport unit 6 from the retracted position shown in FIG. 3 to the transport position shown in FIG.

Further, when the exposure position transport unit 6 is moved from the retracted position to the transport position, when the exposure position transport unit 6 reaches the predetermined transport position by the positioning pin 71, a position detection sensor (FIG. (Not shown), and the detection result is
And the arm drive motor 77 is driven by the control of the controller 5 to swing to a position where the fixed arm 73 is pressed against the frame 11.

In the case of maintenance of the exposure position transport unit 6, when the operator inputs, for example, a keyboard to perform the maintenance work to the controller 5, the controller 5 releases the fixed arm 73 in the fixed state. A command to release the fixing is output to the arm driving motor 77, and the fixing arm 73 swings in the fixing releasing direction, and thereafter the same process as that for paper jamming is performed.

In the above embodiment, when the paper is clogged,
During the maintenance work, the operator pulls out the exposure position transport unit 6 manually. Under the control of the controller 5, the exposure position transport unit 6 is automatically moved from the transport position to the retracted position or from the retracted position to the transport position by motor driving. You may do so.

As described above, according to this embodiment, when paper is clogged in the exposure position transport unit 6 or when the exposure position transport unit 6 and the exposure head 25 are maintained, By horizontally moving the exposure position transport unit 6 to the retracted position, a work space can be formed between the exposure position transport unit 6 and the exposure head 25, and maintenance such as an operation of removing the printing paper P and cleaning of the rollers. Work can be performed easily.

As a result, without moving the exposure position transport unit 6 from the machine body 1, it is possible to take out a paper jam or perform a maintenance operation simply by moving the exposure position transport unit 6 to the retracted position.

In this embodiment, the positioning pin 7 for positioning the exposure position transfer unit 6 at a predetermined transfer position is used.
1 and the exposure position transport unit 6 at the transport position
Since the fixing means 7 having the fixing arm 73 for fixing the exposure unit 1 to the exposure position 1 is provided, even when the exposure position transfer unit 6 is returned from the retracted position to the transfer position by the positioning pin 71, it can be easily moved to the predetermined transfer position where the focus surfaces coincide. And the fixed arm 73 moves the exposure position transport unit 6 to the frame 1 at a predetermined transport position.
1 can be securely fixed.

Since the exposure position transport unit 6 can be fixed to the frame 11 while the positioning pin 71 is constantly pressed against the contact surface 72, the exposure position transport unit 6 is fixed to the exposure position transport unit 6 with some external vibration. Is input, the exposure position transport unit 6 is reliably maintained at a predetermined transport position without shaking.

As a result, the transfer surface of the exposure position transfer unit 6 does not deviate from the exposure surface (focus surface), and the amount of shift can be kept within the specified range of focus and color shift. The stability of focus can be improved.

Further, there is no need to directly scan and correct the printed out print, and the correction function can be automated.

Further, a scanning device such as a flatbed scanner is not required, which is advantageous in cost and space.

Further, in the present embodiment, the exposure position transport unit 6 is configured to move horizontally in a direction orthogonal to the transport surface when transporting the photosensitive material. Since the space retracted from the head 25 can be made as small as possible, the space for installing the exposure position transport unit 6 can be made small, and the entire photographic processing apparatus does not become large.

Further, since the exposure position transport unit 6 is configured to move linearly and horizontally, the structure of the moving mechanism can be simplified without complicating the structure, so that the cost of components can be reduced.

Further, since the exposure position transport unit 6 is configured to be horizontally movable on the frame 11, the exposure position transport unit 6 can be supported on the entire support surface 12 of the frame 11. The frame 1 of the exposure position transport unit 6 has a possible configuration.
Rigidity when attached to 1 can be increased, and vibration resistance can also be improved.

In the present embodiment, the exposure position transport unit 6 is configured to move horizontally with respect to the exposure head 25. 6 may be configured to swing and move between a transport position and a retreat position.

According to the first aspect of the present invention, there is provided a linear exposure head for printing image data in a line on a photosensitive material, and a photosensitive material is loaded onto an exposure surface exposed by the exposure head. In a photographic processing apparatus having an exposure position transfer unit having a transfer mechanism for unloading, the exposure position transfer unit is movably attached to a body at a transfer position close to the exposure head and a retreat position separated from the exposure head. In the event of a paper jam in the exposure position transport unit or during maintenance work, the paper was jammed only by moving the exposure position transport unit to the retreat position without removing the exposure position transport unit from the machine. Maintenance work such as taking out the printing paper and cleaning the rollers can be easily performed.

According to a second aspect of the present invention, in the photographic processing apparatus according to the first aspect, the exposure position transport unit is configured to be movable in a direction orthogonal to a transport surface when the photosensitive material is transported.

Further, since the exposure position transport unit is configured to move linearly, the structure of the mechanism for moving the exposure position can be simplified without complicating the structure, so that the cost of components can be reduced.

Further, when the exposure position transport unit is installed so as to be horizontally movable with respect to the machine, the entire lower surface of the exposure position transport unit can be supported on the machine side. While being movable, the rigidity of the exposure position transport unit when it is attached to the body can be increased, and the vibration resistance can be improved.

According to a third aspect of the present invention, in the photographic processing apparatus according to the first or second aspect, a fixing means for positioning and fixing the exposure position transport unit to a predetermined transport position is provided. Therefore, even when the transfer unit is moved from the retreat position to the transfer position, it can be easily positioned at the predetermined transfer position where the focus surface coincides, and even if some external vibration is input to the exposure position transfer unit. The exposure position transport unit can be securely fixed to the machine body at a predetermined transport position without swinging the exposure position transport unit.

As a result, the transfer surface of the exposure position transfer unit does not deviate from the exposure surface (focus surface), and the amount of shift can be kept within the specified range of focus and color shift. Focus stability can be improved.

Further, it is not necessary to directly scan and correct the printed out print, and the correction function can be automated.
