It is sandwiched between a pair of rotating transport rollers 4, 4, and guided to a liquid tank 2 (the one at the right end in FIG. 1) for the developing process. Then, the paper 13 is guided in the feeding direction B along the inner peripheral surface 14 of the liquid tank 2 by the conveying force of the rollers 4, 4, and is guided by the pair of liquid squeezing rollers 5, 5. The liquid is squeezed out while being held in place and sent to the liquid tank 2 (the one in the center of Figure 1) for the bleach-fixing process. Finally, the paper 13 is washed with water in the liquid tank 2 of the washing process (at the left end in FIG. 1), and is sent out from the liquid squeezing rollers 5, 5 at the left end, completing the development.

As shown in FIGS. 2 and 3, the head section 11 has a cover body 9 which is made up of a guide plate section 7 on which the photographic paper 13 slides and a light shielding plate section 8 that blocks light.
and a head body 10 to which the lid body 9 is pivotally attached so that it can be opened and closed.

Specifically, the guide plate part 7 is formed into a substantially flat plate shape, and has a bent part 15 with both ends bent at right angles so as to guide the paper 13 in the unfolded state and to block light in the closed state. 15, and a locking piece 16 with a Z-shaped cross section on the tip side.
will be established.

Furthermore, the light-shielding plate part 8 includes a light-shielding plate main body 17 that covers the guide plate part 7 from above in the closed state.
and a locking member 18 that slidably locks the locking piece 16 of the guide plate portion 7 in the longitudinal direction.

Specifically, the light shielding plate main body 17 is formed into a substantially flat plate shape having bent parts 19, 19 bent at right angles at both ends, and has a shape at the tip to facilitate opening and closing operations. A projecting piece 27 is provided in a protruding manner. Further, the locking member 18 is formed in a substantially rectangular shape with a long hole 20 for locking the locking piece 16 .
The locking member 18 is connected to the light shielding plate main body 17.
It is fixed to the light shielding plate main body 17 via a plurality of convex portions 21 provided at the middle or upper part of the inner surface.

Further, the head main body 10 has openings on the paper 13 carry-in side and the paper feed-out side to serve as a paper carry-in inlet 22 and a paper feed-out port 23, respectively.
A recess 24 into which the tip of the bent portion 15 of the guide plate portion 7 is fitted, and a recessed portion 25 into which the bent portion 19 of the light shielding plate portion 8 is fitted. ，
It is formed by appropriately bending it so as to have a diameter of 25.

Therefore, the guide plate portion 7 formed as described above
And the light shielding plate part 8 includes a locking piece 16 and a locking member 18.
and a suitable number of hinges 2.
