Next, the operation of this embodiment will be described. When the opening / closing lid 18B is opened in the dark room, the attachment / detachment detection pin 34 is retracted via the interlocking mechanism (not shown), and the light shielding member 30 is moved to the retracted position. With the opening / closing cover 18B opened, the reel 146 is taken out, and is taken out of a new paper roll 2.
1 is fitted into the core 140.

Accordingly, the drum 160 is inserted into the core 140 of the printing paper 22, and the drum 160 supports the printing paper 22. At this time, the flange 1 is guided by the guide portion 206.
The stopper 210 reciprocates with respect to 74, and the engagement or disengagement state is changed by the reciprocation.
Therefore, the flange 174 can be once removed from the drum 160 and the core 140 can be fitted.

However, since one flange 174 is previously screwed to the drum 160 with the screw 246, the reciprocation of the stopper 210 is restricted, and the stopper 210 is stopped in the engaged state, and the flange 174 is fixed. .
Therefore, the one flange 174 does not inadvertently disengage from the drum 160, and the mounting position of the photographic paper 22 does not shift even in a dark room.

Then, the paper roll 2 supported by the drum 160 and restricted in position by the pair of flanges 174.
1 is mounted on the magazine body 18A as an outer frame after the held reel 146 is inserted, and then inserted until the leading end of the printing paper 22 reaches the leading end of the paper port 26. When the opening / closing lid 18B is closed after the paper roll 21 is loaded, the paper port 26 moves to the light shielding position in conjunction with this, and the inside of the paper port 26 is shielded from light while the leading end of the photographic paper 22 is nipped. When the opening / closing lid 18B is closed, it is locked by the lock mechanism 25.

After loading the paper roll 21, the magazine 1
8 is placed on the magazine table 46. When the operation handle 54 is rotated from the position indicated by the two-dot chain line to the position indicated by the dotted line, the plate 48 moves to the left along with the magazine table 46 by the engagement between the roller 50 and the groove 48A. If the loading detection sensor 56 is turned on during the movement of the magazine table 46,
The controller rotates the pulse motor M1 forward, and the pulse motor M1 is transmitted to the feed roller pair 28 via the paper supply gear system FG, so that the feed roller pair 28 rotates.

When the magazine handle 46 is moved by further rotating the operation handle 54, the magazine 18 is set at the mounting completed position. Immediately before this mounting is completed, the detachment detection pin 3
4 contacts the projection 38, so that the light shielding member 30
6 and open the paper port 26. Immediately after this, the feed roller pair 28 is inserted into the notch 2 of the paper port 26.
6A while rotating, the leading end of the printing paper 22 is held by the feed roller pair 28. When the leading end of the photographic paper 22 passes through the feed roller pair 28 and is detected by the passage sensor 60, the forward rotation of the pulse motor M1 stops.

When the mounting of the magazine 18 is completed, the photo sensor 42 reads the paper information from the signal section 40, and
This is sent to the controller. This controller adjusts the width of the variable guide 72 and adjusts the width of the variable paper mask 8.
Adjust the size of 6.

By the rotation of the pair of feed rollers 28, the leading end of the printing paper 22 reaches the main feed roller 114 via the exposure stage 84. This main feed roller 11
4 is rotated by the pulse motor M2, so that the leading edge of the photographic paper 22 is held and fed. When the leading end of the printing paper 22 is detected by the passage detection sensor 120, the rotation of the pulse motors M1 and M2 stops.

After the pulse motors M1 and M2 are stopped, the motor 66 rotates to retract the guide cam 64 to the position shown by the solid line. Immediately thereafter, the pulse motor M1 rotates forward, and the printing paper 22 drawn from the magazine 18 forms a loop 70. When the loop 70 reaches a predetermined amount (at least one frame), the loop sensor 68 is turned on to stop the forward rotation of the pulse motor M1.

As described above, the paper loading is automatically performed only by loading the magazine 18, and the apparatus enters the print standby state. Negative film 9 for film carrier
After setting 2, the user operates a keyboard (not shown) to instruct printing, and a photometric unit (not shown) measures the number of frames to be printed on the negative film.
Various printing exposure amounts are calculated from the obtained photometric values and exposure information such as sensitivity and surface type, and the filter setting position of the filter unit 98 is adjusted in accordance with the printing exposure amounts.
After the adjustment of the filter, the black shutter 104 operates to print and expose the photographic paper 22 set on the exposure stage 84.

When the frame of the negative film is printed and exposed on the photographic paper 22, the pulse motor M2 rotates by a predetermined amount to convey the photographic paper 22 by one frame. This causes the printed portion to be transported toward the loop 130 and the unprinted portion to be pulled out of the loop 70. This loop 70
When the loop amount is decreased, the loop sensor 68 is turned on, so that the pulse motor M1 rotates forward to draw out the photographic paper 22 from the magazine 18 and send it into the loop 70. The pulse motor M1 rotates until the loop sensor 68 is turned off, and constantly stores a predetermined amount of the photographic paper 22 in the loop 70.
