DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 4 and FIG. 5 schematically show a printer processor 10 in which a transport path switching mechanism according to this embodiment is used. (Schematic Description of Printer Processor) The photo printing unit 12 constituting the printer unit of the printer processor 10 has a structure in which a paper magazine 14 in which photographic printing paper P is stored can be loaded. The photographic printing paper P sent out from the paper magazine 14 is cut into a desired length by the cutter 16, and then placed on the suction belt 18 and stopped to be conveyed on the optical axis S of the exposure light beam.

A large number of small holes are formed in the suction belt 18 over the entire area, and a suction force for sucking the printing paper P from the suction fan 22 is applied through the small holes formed on the upper surface of the duct 20. It is supposed to be done.

The casing 10 of the printer processor 10
On the upper surface of A, a light source box 26 in which a light source 24 is arranged
Is provided. The side wall of the light source box 26 is opened, and the diffusion box 28 is inserted into this opening.
A mirror and a diffusing plate are provided in the diffusing box 28 so that the light amount of the light source 24 is large at the exit and is flat.

At the bent portion of the diffusion box 28,
The light rays of the light source whose color tone is adjusted by the three sets of CC filters 30 arranged in the light source box 26 are bent from the horizontal direction to the vertical direction.

The light beam bent in the vertical direction passes through the negative film N set on the negative carrier 32 placed on the casing 10A and becomes an exposure light beam. The exposure light beam passes through the exposure lens unit 34 and forms an image of the negative film N on the photographic printing paper P arranged in the lower area.

Here, the photographic paper P on which the black shutter 35 has been opened and the image printing has been completed is guided by the guide roller 3
It is nipped between 6 and the pressing roller 38, and is conveyed through a conveying path 40 to a processing tank 42 for carrying out each processing such as development, bleach-fixing and washing.

Finally, the photographic printing paper P washed with water in the washing tank is conveyed to the drying processing section 44 arranged above. The drying processing section 44 includes a drying section 52 and a transport section 54. The dried photographic printing paper P is guided by a guide plate 136 that constitutes a transport path switching mechanism, and is discharged from the discharge port 48 or the concentration measuring unit. It is discharged to the outside of the machine via 50. (Control Strips Cassette) As shown in FIGS. 2 and 3, the control strips cassette 60 is a rectangular box body, and the control strip 64 is attached to the hollow portion 62.
