等の課題があった。However, the above-mentioned conventional technology has the following problems. Generally, when recording with a thermal transfer printer, the platen and AI! Recording is performed by applying pressure between the ink film and the recording paper between the recording head and the roller, and the printer/printer is not used except when recording.
Since the pressure on the recording head and rollers is released, a very large paper feeding force is required to feed the paper during recording, and the paper pressing force and shaft loss of the paper feeding means are also much larger than when not recording. However, when paper feeding is carried out using a dedicated drive source, a high torque drive source is required, resulting in an expensive device.
そこで本発明はこのような課題を解決するもので、その
目的とするところは、紙送り精度を低下させることなく

位置にある。Next, the paper feed roller 22 is rotated in the direction of arrow G by a drive means (not shown), and the automatically fed recording paper P3 is conveyed in the direction of arrow H. At the same time, the drive means (not shown) rotates the paper feed roller 22 in the direction of arrow 1. 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 is exerted between the recording paper P3 and the paper feed belt 15 due to the paper ejection roller 34 which is tilted by its own weight on the paper feed belt 15, and the recording paper P3 is It is transported in the direction of arrow H and securely stored in the stacker 8. After recording is completed, the head frame 32 shown in FIG. 2 is rotated in the direction opposite to the direction of the arrow F to release the pressure of the head 25 and rollers 28 and 28 against the platen 26, thereby setting the head frame 32 in a reset state. The third bar 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 and rollers 28 and 29 are in a position where they do not interfere with the replacement of the film cassette 11.

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. Generally speaking, 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. The force and the horizontal axis of the paper feeding means are also very thick (a high torque motor is required as the paper feeding drive source, but as shown in Figure 4, the paper feeding drive source is a PM type stepping motor 35). The driving force is transmitted to the paper feed roller 22 and paper feed drive shaft 12 via the reduction gear 36, and the film winding f [reduction gear 38, support gear 39, and paper feed conveyance load are removed from the source DC motor 37] The torque limiter 40, which can transmit a force smaller than the operating load of the paper feeding means, transmits a force smaller than the operating load of the paper feeding means excluding the paper feeding transport load to the DC motor from the recording paper transport speed from the stepping motor 35. 37
The paper feed drive shaft 12
In addition to allowing the use of a low-torque motor, the paper feed transmission force from the DC motor 37 is only a force smaller than the operating load of the paper feed means excluding the paper feed conveyance load. There is no problem with feeding accuracy. Film winding is decelerated by DC motor 37 in mJ.
The driving force is transmitted to the winding core 10 via If38. When winding only the film without paper feeding, the support gear 39 and the reduction gear 38 are rotated by a drive means (not shown) in the direction of the arrow to prevent the load of the paper feeding system from being applied to the film winding. It has a structure that cancels the result.

す。FIG. 6 shows how to replace consumables when the mechanical section is in a reset state. To replace and replenish the recording paper P1, listen to the paper magazine door 3, pull out the paper magazine 7 while rotating it in the direction of arrow 1, set the recording paper, and then push the paper magazine 7 back in the direction opposite to the direction of arrow 1. To replace the film cassette 11, open the film cassette door 4, pull out the film cassette 11 in the direction of arrow J, push in a new film cassette in the opposite direction to the direction of arrow J, and close the film cassette door 4. Further, the recording paper P2 on which recording has been completed is removed by opening the stacker door 5.

、低価格の装置を供給出来るという効果が期待出来る。As described above, according to the present invention, the paper feeding means receives power from both the paper feeding drive source and the other driving source, and the torque limiter is interposed between the other driving source and the paper feeding means, The transmission force regulated by the torque limiter is smaller than the operating load of the paper feeding means excluding the paper feeding conveyance load, and the conveying speed of the paper feeding means by the other drive source is faster than the conveying speed of the paper feeding means by the paper feeding drive source. In addition, a clutch mechanism that can cancel power transmission is interposed between other drive sources and the paper distribution feeding means, and power transmission from the distribution driving source to the paper feeding means is canceled except during recording. It is possible to use a low-torque drive source as the paper feed drive source without reducing accuracy, and it is expected that a low-cost device can be provided.
