PROBLEM TO BE SOLVED: To detect a faulty setting of a unit in a main body frame with a simple constitution and to reduce the cost of a photographic processing device. SOLUTION: When the unit 11b reaches a reference position or a position in direction B deeper than the reference position by pressing the unit 11b in the direction B, a positioning part 14 provided in the unit 11b is fixed by a positioning block 15 provided in the main body frame 3a, whereby the unit 11b is fixed in the main body frame 3a. Meanwhile, when a user releases his (her) hand from the unit 11b before the unit 11b reaches the reference position, only energizing force in a direction A by a plunger unit 13 acts on the unit 11b, so that the unit 11b projects in the direction A. The user can recognize a faulty setting of the unit 11b in the main body frame 3a by recognizing the projection of the unit 11b.
