Due to the urging force, the hopper lever 17 rotates in the direction of arrow C about the fulcrum 42, the hopper 16 is lifted in the direction of arrow B about the fulcrum 43, and the recording paper P1 is pressed against the paper feed belt 15. At the same time, Due to the urging force of the spring member 101, the separator 18
rotates in the direction of arrow C about the fulcrum 42, and the friction member 19 attached to the separator 18
Pressed to 5. In this state, automatic paper feeding is started by rotating the paper feeding drive shaft 12 in the direction of arrow E by a drive means (not shown). As the paper feed belt 15 rotates in the direction of arrow E, one or more recording papers are transferred to the separator 18.

支障とならない位置にある。Next, the paper feed roller 22 is rotated in the direction of the arrow G by a drive means (not shown), and the automatically fed recording paper P3 is conveyed in the direction of the arrow H, and at the same time, the winding core 10 is rotated in the direction of the arrow 1 by the drive means (not shown). Recording is performed while rotating the ink film Q to convey the ink film Q. At this time, the recording paper P3 is guided on the guide chip 33 and is conveyed in a direction in which it is pressed by the paper discharge roller 34 and the paper feed belt 15. In the case of color recording, the paper feed roller 22 is rotated in the direction of arrow G during recording and in the opposite direction to arrow G when returning the paper, and the recording paper P3 is rotated in the direction of arrow H and counter-H by a predetermined amount three or four times. After reciprocating, the recording paper P3 is discharged in the direction of arrow H. The paper feed roller 22 and the paper feed belt 15 are rotated by the same drive source in the directions of arrows E and G shown in FIG. When the paper is ejected until it comes off the nipping part, a frictional force acts between the recording paper P3 and the paper feed belt 15 due to the paper ejection roller 34 that rests on the paper feed belt 15 under its own weight! 2 Recording paper P3 is transported in the direction of arrow H and is securely placed in the stacker 8.
Since the recording paper is stored in the device, no recording paper remains inside the device, which prevents paper jams. After the recording is completed, the head frame 32 shown in FIG. The reset state is also the mechanical state when the film cassette 11 containing the recording paper P1 and the ink film Q is replaced, and the head 25
The rollers 28 and 29 are located at a position where they do not interfere with the replacement of the film cassette 11.

との果合を解除する構造になっている。FIG. 5 shows a drive transmission mechanism for rotating the paper feed roller 22 and the paper feed belt 15 and for winding the film. In general, the load on the paper feeding system is greater when recording than when not recording, as the head 25 and rollers 28 and 29 shown in FIG. 2 are suppressing the platen 26, and a high torque motor is required. As shown in FIG. 4, driving force is transmitted from the paper feed motor 35 to the paper feed roller 22 and paper feed drive shaft 12 via the reduction gear 36, and the drive force is transmitted from the film motor 37 to the reduction gear 38, the support gear 39, and the paper feed conveyance. A torque limiter 40 capable of transmitting a force smaller than the operating load of the paper feeding means excluding the load is transmitted to the paper feed drive shaft 12, which is smaller than the operating load of the paper feeding means excluding the paper feeding conveyance load. A torque motor can be used. For film winding, driving force is transmitted from the film motor 37 to the winding core 10 via a reduction gear 38. When winding only the film without paper feeding, the support lever 41 is rotated in the direction of the arrow by a drive means (not shown) to prevent the load of the paper feeding system from being applied to the film winding.
It has a structure that cancels the relationship between the two.

To replace and replenish the recording paper P1, please use the paper machining door 3. After pulling out the paper magazine 7 while rotating it in the direction of arrow 1 and setting the recording paper thereon, the vapor magazine 7 is pushed in again in the direction opposite to the direction of arrow 1. To replace the film cassette 11, open the film cassette door 4 and move the film cassette 11 in the direction of arrow J.

Since the paper ejecting flow is pressed by its own weight onto the paper feeding means near the section, it is expected that a space-efficient and low-cost device can be provided, as well as ensuring that the recording paper is stored in the stacker after recording is completed. You can expect the effect that it can be done.
