Knead and record the preparation is completed 5, then Pressing the record button starts the recording operation. By the way, when the recording of information to the recording medium is finished, the recorded part and the following unrecorded 7916 minutes are cut, and the recorded part is wound into the winding magazine and wound. The removal magazine is removed from the phototypesetting machine body and the recording medium is subjected to the developing process, but the removal magazine cannot be removed from the γγ typesetting machine body during recording mode, and must be removed only after the recording operation is completed. However, since the recording medium is photosensitive, when removing the VC winding magazine, the recording medium path on the winding magazine side and the phototypesetting machine body side must be shielded from light in advance. The present invention is designed so that the light shielding can be performed exactly 6'ε when the take-up magazine is removed after recording is completed.
A displacement member that can be operated from the outside is provided, and when the displacement member is displaced to a predetermined position, it blocks light from the artificial side of the recording medium passage of the winding magazine and the exit side of the recording medium passage of the pulling body, and This invention is designed to release the winding magazine from the machine body.The present invention will be explained below based on the drawings.The illustrated laser phototypesetting machine has a supply magazine containing all rolled recording media attached to the phototypesetting machine body. When the recording medium is set in the magazine, the recording medium in the magazine is automatically fed to the recording start position by the feeding mechanism. It is a schematic diagram of a feeding mechanism of such a laser phototypesetting machine,

This condition is shown by the solid line in FIG. On the other hand, when the lever 26 is pulled, the light-shielding bin 31 on the recording medium side of the winding magazine 13, which is engaged with the groove 28a of the bar 28, slides as shown in FIG. Since it is moved at t1, the spring 32 is activated and the light shielding sponge 33 is separated from the guide plate 22, and as a result, the light shielding on the recording medium side of the winding magazine 13 is also released. The arrow indicates the feeding path of the recording medium. Next, when the recording button (not shown) is turned on, the laser beam L is projected onto the recording medium 11 at A and a shown in FIG.
Image information is recorded by R. When the cut button (not shown) is pressed after recording is completed, the drive roller 19 in the phototypesetting machine main body 11 moves in the same direction as the winding magazine, and the light-shielding sponge 33 comes into contact with the guide plate 22, thereby shielding the winding magazine 13 from light. It will be done. In this way, when the lever 26 is pressed, the main body 11 and the take-up magazine 13 are automatically shielded from light, so that the supply magazine 13 can be removed in a bright room. FIG. 5 is a plan view of the slide lever 28. Three engagement holes 28b are formed in the slide lever 28, and during the recording mode, a headed pin 35 (FIGS. 2 and 4 ) are engaged. However, lever 26
When is pushed in the direction of the arrow, the slide lever 28 slides and the headed bottle 35 is disengaged from the engagement hole 28b, so that the width magazine 13 becomes removable. In this way, when the lever 26 is pressed after the recording operation is completed, the take-up magazine becomes removable, and the recording medium path is shielded from light on the take-up magazine side and the phototypesetting machine body side. Take roller 1
3a is rotated by an external motor (not shown) for a predetermined period of time set by a timer, so that the recording medium 11. , I
The recorded part of : should be placed in the spring magazine 13 at $:. Next, remove the saving magazine 1. (Z, '7 will be explained.) As shown in Fig. 3, when the lever 26 is pushed to the chain line position, it slides and the bar 28 moves to the right, so that the spring 34
The lever 35, which is biased and released from f7, moves clockwise around point P to the position In shown by the chain line.
