When the photosensitive material 14 is inserted from the insertion opening 16 in a substantially horizontal state, it is held between the rollers 18 . By driving this roller 18, the photosensitive material 14 is conveyed and conveyed toward the developing tank 28. When the leading end of the photosensitive material 14 reaches an upper roller 36 disposed in the developer tank 28, the photosensitive material 14 is held between the rollers 36 and conveyed toward the bottom of the developer tank 28.

The photosensitive material 14 that has passed through the roller 36 is transferred to the guide plate 8
It is guided by the guide surface 2 and held between the lower rollers 36. By being held between the rollers 36, the photosensitive material 14
is reversed, guided by the guide surface of the guide plate 82, held between the upper rollers 36, and discharged from the developer surface of the developer tank 28.

The photosensitive material 14 discharged from the developing tank 28 is transferred to a roller 40.
．． 42 and conveyed toward the fixing tank 30.

In the fixing tank 30, a roller 36 is used as in the developing ff28.
The toner is conveyed in a substantially U-shape within the fixing tank 30 by the guide plate 82 , and then similarly conveyed to the washing tank 32 where it is held between the rollers 50 .

The photosensitive material 14 held by the rollers 50 is successively held by the rows 550 that extend to the drying section 44, passes through the guide plate 48, and reaches the drying section 44.

Warm air is blown into the chamber 52 of the drying section 44, and the warm air is blown out from the slit holes 56. As a result, the photosensitive material 14, which is held between the pair of rollers 54 and conveyed in a substantially horizontal state, is blown with hot air substantially evenly, and is dried. Photosensitive material 1 subjected to drying treatment
4 is discharged from the discharge port 58 and stored in the magazine 86, and the processing of the photosensitive material 14 is completed.

The length display control during processing of the photosensitive material 14 will be explained below in accordance with the flowchart of FIG. 5 and the time chart of FIG. 6.

temperature sensor 1 and moves to step 201.
00 detects the development temperature, then step 20
2, the developing temperature is displayed on the display section 72. In the next step 204, it is determined whether or not the photosensitive material detection sensor 80 has detected the photosensitive material 14. If the determination is negative, that is, the photosensitive material 14 has not been detected, step 201
Move to. If an affirmative determination is made in step 204, that is, the photosensitive material 14 is detected, the process moves to step 206, and the display content of the display section 72 is switched to display the processing length, and then, in step 208, the display length is set to 0. In step 210, L is displayed on the display B72, and in step 211, the integrated value TL is displayed on the display section 70. That is, when the leading edge of the photosensitive material 14 is detected, the display switches to the length display, and the processing length L and integrated value TL at this time are 0.
becomes.

In the next step 212, it is determined whether a predetermined time (for example, 1 second) has elapsed. Here, if it is determined that a predetermined period of time has elapsed, the process moves from step 212 to step 214 to determine whether or not the photosensitive material 14 has been detected, that is, whether the rear end of the photosensitive material 14 has passed the photosensitive material detection sensor 80. If the photosensitive material 14 is detected, the process moves to step 216, where 1 is added to L (LL+1),
Further, in step 218, after adding 1 to TL (TL 4
-TL+1), the process moves to step 210.

If it is determined in step 214 that the photosensitive material 14 is not detected, it is determined that the rear end of the photosensitive material 14 has passed, and the process proceeds to step 220.

In step 220, after switching the display on the display unit 72 to a waiting time display (counting down in 1 second increments to indicate how many seconds remaining the photosensitive material 1#J14 will be taken out of the automatic developing machine 10 and the processing will be completed), In step 222, it is determined whether or not to end the process. If the process is to end, the process moves to step 224 and the integrated value TL is stored in the RAM 94. Further, if the process is to be continued, the process moves to step 201. At this time, the display on the display unit 70, that is, the integrated value TL is displayed as is.

In this embodiment, the photosensitive material detection sensor 80 is inserted into the insertion slot 1.
Although it is installed near the discharge port 58, it may be placed anywhere near the discharge port 58 or on the conveyance route.

Further, although the temperature of the processing liquid is displayed for the developer, the temperature of other processing liquids may be displayed.

Incidentally, the flashing processing ready display in FIG. 6 means that the next photosensitive material may be inserted, but the previous photosensitive material
Indicates that 4 remains.
