As shown in FIG. 2, the upright conveyance means 32 is an interface rack that is removably installed, and is provided with a plurality of pairs of conveyance rollers 44 and 46 that sandwich the photosensitive material F, and these are arranged in parallel. It is pivotally supported by a pair of side plates 48 (the side plate on the near side is not shown in FIG. 2), and rotates by receiving the driving force of a motor (not shown). A guide plate 50 is provided between these pairs of transport rollers, and lifts the photosensitive material F fed out horizontally from the exposure section 30 from a low position to a high position, turns it over at the upper end, and transfers it to the developer tank 12. It is designed to be supplied to the upper part.

A cassette 52 is inserted into the upper part of this upright conveyance means 32 by passing through the drying section 22.

As shown in FIG. 3.4, in the cassette 52, both ends of the plate-shaped cassette body 540 in the width direction are bent at right angles to form bent portions 54A extending parallel to each other.
The distal ends of 4A are abutting parts 54B bent at right angles in the direction of separation from each other, and the distal ends of this abutting parts 54B are further bent at right angles to form holding parts 54C parallel to each other. The lid plate 58 has a flat plate shape and can be accommodated between the holding parts 54C, and has dimensions such that both ends in the width direction abut against the holding parts 54C. This cover plate 58 is in close contact with the cassette body 54,
A rectangular strip housing portion 62 is formed between the bent portions 54A.

Therefore, a control strip (not shown) on which a predetermined image has been printed under predetermined conditions is inserted into the IJ lapse container 62. To prevent outside light from inadvertently entering the inserted control strip from both ends of the cassette 52, light-shielding felt materials 64 and 66 are attached to the inner periphery of the ends of the strip accommodating portion 62, respectively.

Further, an insertion plate 68 can be inserted into the strip accommodating portion 62 from one end, and the insertion plate 68 is inserted into the strip accommodating portion 62 by holding the bending pressing portion 68A formed at the protruding tip of the insertion plate 68.
