The film F guided to the transport path 64 by the guide rollers 82 is nipped and transported by the transport rollers 84, and returned to the automatic rewinding device 16 via the guide rollers 86.

At this time, the cartridge 12 has already been rotated by -90 degrees (see FIG. 4) by the driving of a stepping motor (not shown) to change the direction of the insertion port 12A, and the film F is directly loaded into the cartridge 12. Rewind.

Next, the case where the film P has not been developed will be described.

As shown in FIGS. 2 to 4, the film P is stored in the cartridge 56,
The film P is pulled out from the inside. When the film P reaches the rear end, the film P is cut by the cutter 70 and separated from the cartridge 56.

The film P is transported to the thermal development processing section 18 along a transport path 72 located below the transport path 64. The transport path 72 is wider than the width of the transport path 64. Like the transport path 64, the transport path 72 is also composed of two rails 73 as shown in FIG. Have been. The rail 73 has a U-shaped cross section, and a concave portion 71 is formed on the opposing side surface.

The bottom wall 71A of the concave portion 71 supports both ends of the film P to be conveyed, and the edge of the film P slides on the side wall 65B to prevent the film P from meandering.

It is discharged from a discharge port 90 formed on the side surface of the thermal developing device 10. The film P is cut into an appropriate length by a cutter (not shown), put into a negative bag, and discharged.

Next, the case where the film F has been developed will be described.

As shown in FIG. 5, the film F is wound around the intermediate cartridge 14 by the automatic winding device 16 in the same manner as in the case where the film F has not been developed.

When the film F is wound around the intermediate cartridge 14, the direction of the intermediate cartridge 14 is changed by 90 degrees by driving a stepping motor (not shown). Then, the film F is nipped and transported by the transport rollers 92, and is directly transported to the image information reading unit 40 along the transport path 94 by the transport rollers 46 via the guide rollers 47.

As described above, the processing corresponding to each film can be performed only by inserting the film into each insertion opening with one heat developing device 10. In this embodiment, the transport path 6
4 and the transport path 72 are arranged vertically, but may be arranged in parallel to the width direction of the film, and the invention is not limited to this.

Next, a heat developing apparatus according to a second embodiment will be described.

In the first embodiment, the transport path 6 for the film F
6 and the transport path 72 for the film P, respectively, in the second embodiment, as shown in FIG. 8, in the section from the transport roller 105 to the image information reading unit 40, one transport path 100 is provided. It is only arranged. The transport route is the same as in the first embodiment, and a description thereof will be omitted.

Next, the transport path 100 will be described.

The transport path 100 is composed of two rails 101 like the transport paths 66 and 72.
The interval of 01 can be changed by a solenoid described later. Thus, the films F and P having different widths can be transported.

More specifically, as shown in FIGS. 9 and 10, the rail 101 is supported by a guide rail 108 so as to be able to contact and separate while keeping a parallel state. This rail 101
A solenoid 102 is fixed to the side plate 110 on the outside.

The plunger 11 of this solenoid 102
2 is connected to the side surface of the rail 101.
When power is not supplied to the solenoid 102, the plunger 112 protrudes due to the urging force of a spring (not shown) provided therein, and the interval between the rails 101 is reduced. At this interval, the film F can be transported.

As described above, the interval between the rails 101 changes depending on whether or not the power is supplied to the solenoid 102. When the power is not supplied to the solenoid 102, the rail 101 has a narrow interval in which the film F can be transported. When power is supplied to the solenoid 102 by a control unit (not shown),
The distance between the rails 101 is increased, and the film P can be transported.

In this configuration, for example, when the cartridge 56 is inserted into the cartridge insertion slot 54 (see FIG. 1), the cartridge 56 is inserted by a sensor (not shown) provided in the cartridge insertion slot 54. Is detected. Next, a detection result is transmitted to a control unit (not shown), and power is supplied to the solenoid 102 by the control unit.

Then, as shown in FIG.
1 is widened, and the film P can be transported. When the film P is discharged from the discharge port 92, power is not supplied from the control unit to the solenoid 102, the interval between the rails 101 becomes narrow, and the interval returns to the interval where the film F can be transported.

Further, even if the cartridge 12 is inserted into the cartridge insertion slot 52, power is not supplied to the solenoid 102, so that the rails 101 are kept at a narrow interval.

As described above, by changing the interval between the rails 101 of one transport path 100, the film F and the film P
Can be conveyed, so that it is not necessary to arrange a plurality of conveyance paths, and the space for the heat developing device can be reduced.

Here, between the rails 101, the rail 1
A transport roller 104 is disposed orthogonal to the longitudinal direction of the transport roller 01 and is rotatably supported by support means (not shown). The transport rollers 104 transport the film F and the film P. The length of the transport roller 104 is slightly longer than the width of the film P so that no trace of the edge of the transport roller 104 is left on the image frames 68 and 76.

For this reason, notches 101A are formed near both ends of the rail 101.
When the distance between the rails 101 becomes narrow, the rail 101 escapes so as not to come into contact with the transport roll 104.

The sensor detects whether or not a cartridge has been inserted into the insertion slot, and supplies power to the solenoid from the control unit. However, an operation provided on the top surface of the heat developing device 10 shown in FIG. The interval between the rails 101 may be changed by pressing a film selection switch of the switch unit 62, and the present invention is not limited to this.

Next, the transport path of the films F and P will be described.

First, the film F transported along the transport path 120 or the film P transported along the transport path 122 is guided to the transport path 100 via the transport roll 105. Then, the film F or the film P is transported along the transport path 100 and passes through the coating tank 114,
It is transported to the development processing section 18.

The heat-developed film F or P is transported through the guide roller 21 to the transport path 100.
Is transported to the image information reading unit 40 by being nipped and transported by the transport rollers 116 and 118. Image information reading unit 4
Since the path after 0 is the same as the first embodiment, the description is omitted.
