A worm 57 and a worm wheel 58 that connect the four and the output shaft 55.

Next, the operation of the guide width synchronizing mechanism C in the photographic processing apparatus of the present invention will be described.

First, by comparing the width information of the photographic printing paper S on which the image of the photographic film F shown in FIG. 2 is printed and the current guide width position obtained from the detector 56 shown in FIG. The motor 53 is rotated after determining the rotation direction.

For example, when the gap between the pair of guides 9a and 9b of the guide width changing means A and B in the submerged rack portion 1 and the drying rack portion 21 is widened, the rotation of the width changing motor 53 causes the output shaft 55 to move. The pinion shaft 45 is shown in FIG.
Rotate in the a direction shown inside. Accordingly, the rotational movement of the motor 53 is caused by the pinion gear 45a and the rack gear 4
6, the linear motion of the slide plate 49 and the rack gear 10 is converted. In the submerged rack unit 1, this linear motion is converted into a rotary motion again by the first transmission shaft 4, and the feed screw shaft 7 is rotationally driven, and the pair of guides 9a, 9a.
b is expanded in the b direction shown in FIG. As a result, the photographic paper S
Is reliably guided by the guides 9a and 9b, and no trouble such as clogging occurs.

On the other hand, also in the drying rack portion 21, the rotation movement of the width changing motor 53 changes the rotational movement of the motor 53 into the linear movement of the second slide connecting means 25 by the pinion gear 45b and the rack gear 47. This linear motion is converted into rotary motion again by the second transmission shaft 24, which drives the feed screw shaft 7 to rotate, and the pair of guides 9
Spread a and 9b in the direction b shown in FIG. As a result, the photographic printing paper S transported from the submerged rack section 1 is reliably transferred and guided by the guides 9a and 9b of the drying rack section 21.

In the photographic processing apparatus of the present invention, the guide width synchronizing mechanism C and the guide width changing mechanism A in the submerged rack section 1 are connected to each other by the rectangular cutout 48 of the slide plate 49 and the rack gear 10. . Similarly, the guide width synchronizing mechanism C and the guide width changing mechanism B in the drying rack portion 21 are connected to each other by the concave portion 52 of the rack gear 47 and the convex piece 27 of the second slide coupling means 25. Therefore, the submerged rack section 1 and the drying rack section 21
The guide width synchronizing mechanism C provided in advance is simply loaded in the developing unit and the drying unit of the apparatus, respectively.
Since a pair of guide widths can be connected to the set value of the printing paper to be conveyed, the guide width can be accurately synchronized. Also, after the loading, for cleaning and inspection work,
Since the submerged rack portion 1 or the drying rack portion 2 can be easily removed, it is very convenient.

[0034]

As described above, according to the photographic processing apparatus of the present invention, the pair of guides are simultaneously moved and synchronized between the guide width changing mechanisms in the rack section of the developing section and the drying section. Since the guide width synchronizing mechanism is provided, the guide widths of the in-liquid rack section and the drying rack section can be set correctly. Therefore, troubles such as clogging and detachment of the printing paper can be prevented, and stable transportation of the printing paper is possible.

Further, the guide width synchronizing mechanism includes guide width synchronizing means including a pinion shaft having two pinion gears and two width adjusting rack gears, and driving means including a width changing motor and a detector. Since it is composed of, the number of parts is small and the structure is simple, so the equipment cost is low.

Further, the in-liquid rack section of the developing section and the drying rack section of the drying section can be attached to and detached from the guide width synchronizing mechanism by slide connecting means. Therefore, simply by loading the submerged rack section and the drying rack section into the main body of the device,
Since the pair of guide widths can be synchronized with the set value, maintenance and workability are improved.
