Further, a conveyor device 136 for transporting the photographic printing paper P in a direction orthogonal to the transport direction of the transport path 84 is arranged at a position adjacent to the rear end of the transport path 84 and one step lower than the transport path 84, The belt 136A of the conveyer device 136 rotates in the direction of arrow C, and the photographic printing paper P is sequentially conveyed to the sorter 138 side for collectively collecting the photographic printing paper P for each negative film N. There is.

A plate-shaped gate 126 is attached at a position facing the rearmost end on the side where the upper sensor 122 is arranged and the upper part of the conveyor device 136 in the conveyance path 84 in FIG. Has been. In the same manner, a plate-shaped gate 128 is attached to the uppermost position of the conveyor device 136, facing the rearmost end on the side where the lower sensor 124 is arranged in the conveyance path 84 in FIG. ing.

These gates 126 and 128 are guided by the guide members 144 and 146, respectively, and as shown in FIG.
It is sandwiched by two pairs of rollers 140 and 142 which are arranged vertically. One ends of the upper rollers 140 and 142 of the rollers 140 and 142 are connected to the motors 130 and 132, respectively.
The rollers 140 and 142 are rotated by the driving rotation of 0 and 132, and the gates 126 and 128 are moved to the right, whereby the gates 126 and 128 are opened and closed, respectively. For example, as shown in FIG. 4, the gate 128 is moved to the right by the rotation of the motor 132, and the gate 128 is moved.

A stopper member 148 is arranged on the upper side and between the guide members 144 and 146.

The motors 130 and 132 are connected to the controller 112, and the controller 1
Since the motor 12 controls the rotation of the motors 130 and 132, the opening and closing of the gates 126 and 128 is controlled by the controller 112.

In other words, when the gate 126 and the gate 128 are opened while being controlled by the controller 112 while the print paper P is on the gate 126 and the gate 128, the print paper P on the opened gates 126 and 128 is opened. Collides with the stopper material 148 and drops onto the belt 136A of the conveyor device 136, and the dropped photographic paper P is conveyed by the conveyor device 136 to the sorter 138 side.

Next, the operation of this embodiment will be described. First,
The sorting device 110 arranges the photographic papers P in two rows on the transport path 60. At this time, the sorting information on which row the photographic paper P transported on the transport path 60 is sorted is stored in the memory in the controller 112. Memorize with.

Therefore, since the memory in the controller 112 stores which row the photographic paper P has been distributed to in the order of exposure, the controller 112 grasps the exposure order and arrangement of the photographic paper P as shown in FIG. There is. still,
Here, P1, P2, P3, P4, P5, P6 ...
The exposure order of the printing paper P is shown.

As shown in FIG. 2, when the photographic printing paper P is arranged in two rows and conveyed side by side to the vicinity of the exit portion of the processor section 72, first, the sensor 124 detects the front end of the photographic printing paper P1. . By this detection, the controller 112 closes the gate 128, and when the sensor 122 detects the leading end of the photographic printing paper P2, the controller 112 is similarly operated.
Closes gate 126.

Next, when the sensor 124 detects the trailing edge of the printing paper P1, the controller 112 similarly moves the gate 128 to the position shown by the chain double-dashed line in FIG.
When the leading edge of the photographic printing paper P3 is detected at 24, the controller 112 similarly closes the gate 128. Similarly, the sensor 12
When the rear end of the photographic printing paper P2 is detected by 2, the gate 126 is moved to the position shown by the chain double-dashed line in FIG. 2 and opened, and when the front end of the photographic printing paper P4 is detected by the sensor 122, the gate 128 is closed.

In this way, the photographic printing paper P is sequentially discharged onto the belt 136A of the conveyor device 136. By repeating this, the photographic printing paper P is conveyed to the sorter 138 side by the conveyor device 136 in the order of exposure and On 138, they are arranged in the order of exposure.

That is, the opening and closing of the gates 126 and 128 provided respectively corresponding to the plurality of sorted rows are controlled by utilizing the detection timing of the printing paper P detected by the sensors 122 and 124 and the sorting information. The gates 126 and 128 are opened and closed so that the printing paper P is accumulated in the order of exposure.

As described above, when the photographic papers P are conveyed in a plurality of rows side by side, the processed photographic papers P come out from the exit portion of the processor unit 72 in a plurality of rows, but the detection timing of the photographic papers P and the distribution information. These can be integrated in the order of exposure by the gates 126 and 128 whose opening and closing are controlled based on

On the other hand, for example, when the printing papers P3 and P4 are reversed and the printing papers P are conveyed side by side as shown in FIG. 5, the timing for opening the gates 126 and 128 is from the printing paper P4. Since it is necessary to drop P3 onto the conveyor device 136 first, the gate 126 is the first and the gate 128 is the first.
Will come later.

In this case, the controller 112 controls the rotation timings of the motors 130 and 132, the gate 128 does not open even if the sensor 124 detects the rear end of the printing paper P4, and the sensor 122 causes the printing paper P3 to move. After detecting the trailing edge and confirming that the printing paper P3 is positioned on the gate 126, the gate 126 is opened to eject the printing paper P3, and then the gate 128 is opened. After this, printing paper P
Since the tip of 5 has already passed through the sensor 124, the gate 128 will be closed immediately.

As a result, even when the printing papers P3 and P4 are conveyed in reverse, the printing paper P3 can be discharged to the conveyor device 136 side before the printing paper P4, and the printing papers P can be stacked in the order of exposure. Will be able to.

As described above, according to this embodiment, even if the photographic papers P are not necessarily arranged in the order of exposure, the photographic papers P
Even if there are plural types of lengths, the printing papers P can be stacked in the order of exposure based on the detection timing and the distribution information of the printing papers P.

In this case, since the arrival time of the photographic printing paper P at the gate is accurately known, it is not necessary to consider a time error when opening and closing the gate.

That is, the sorting device 110 sets the printing paper P
When the gate is opened and closed based on the elapsed time from the time of distribution, if a trouble such as a power failure occurs, the elapsed time becomes meaningless as information, but in the present embodiment, such a time It is not necessary to consider such an error. Therefore, according to the present embodiment, it is possible to deal with such a trouble.

A second embodiment of an integrated device for a photographic printer according to the present invention is shown in FIG. 6, and this embodiment will be described based on these drawings. The same members as those described in the first embodiment are designated by the same reference numerals, and the duplicate description will be omitted.

Therefore, the gates 172, 174, and 172 are arranged in the order of detection of the leading edge of the printing paper P by the sensors 162, 164, 166.
Open 176. Further, since the photographic paper P5 is longer than the photographic paper P6, the photographic paper P6 is the gate 17 first.
However, even in this case, the sensor 164 for detecting the photographic paper P5 detects the leading edge of the photographic paper P before the sensor 166 for detecting the photographic paper P6.

Therefore, the controller can determine that the printing paper P5 has come out of the processor unit 72 before the printing paper P6. Therefore, even if the printing paper P6 gets on the gate 176 first, the gate 176 is not opened and the printing paper P6 is not opened. The gate 174 on which the photographic printing paper P5 rides after the rear end of the paper P5 passes the sensor 164.
Can be opened first to discharge the photographic printing paper P5 onto the conveyor device 136, and then the gate 176 can be opened to discharge the photographic printing paper P6 onto the conveyor device 136.

Therefore, in the first embodiment, the opening and closing of the gate is controlled by the detection timing and the distribution information. However, in the present embodiment, the printing paper P accumulated in the exposure order is not required for the distribution information.
Can be accumulated.

That is, the opening and closing of the gates 172, 174, and 176 respectively provided corresponding to the plurality of sorted lines are controlled by utilizing the detection timings of the leading edge and the trailing edge of the printing paper P, respectively. The gates 172, 174, and 176 are opened and closed so that the printing paper P is discharged in the order of detecting the leading edge of the sheet.

In the above embodiment, the gate may be a plurality of gates of four or more, and the structure of the gate is not limited to the plate-like one, and may have another structure. Further, the sensor is not limited to the optical type, and may be, for example, a sensor that contacts a photographic paper and mechanically detects it.
