[Prior art]

 As is well known, some conventional printer devices have a built-in recording paper winding mechanism for winding printed-out recording paper. As shown in FIG. 2, the conventional recorded recording paper winding mechanism 21 built in the printer device causes the recorded recording papers C and S to follow the preset recording paper feed lines F and L. It is configured to feed and wind around a recording paper take-up shaft provided in the recording paper feed lines FL, specifically, the paper feed motor 22 and the paper feed motor. A motor 22 is provided with a paper feed roller 24 mechanically interlockingly connected via a power transmission means 23 such as a belt, and the paper feed roller 24 feeds the recorded recording papers C and S to the recording paper. It is configured to send along the lines FL. The paper feed roller 24 is urged toward the recorded recording paper C.S. so as to apply a feeding force to the recorded recording paper C.S on the recording paper feed line F.L in the feeding direction. . On the other hand, the recording paper take-up shaft 25 provided in the recording paper feed lines F and L is mechanically interlocked with the paper feed motor 22 through a power transmission means 26 such as a belt.

In the recorded recording paper winding mechanism 21 having the above-described conventional configuration, the recording paper winding shaft 25 has a slip mechanism 27, and a winding bobbin 28 is arranged around the outside of the slip mechanism 27. The recording sheets C and S that have been recorded are wound around the winding bobbin 28. The slip mechanism 27 is intended to absorb a change in the winding force of the recording paper winding shaft 25 due to a change in the recording paper winding diameter. As the size increases, a slip action is generated between the recording paper winding shaft 25 and the winding bobbin 28 to absorb the change in the winding force. The conventional recorded recording paper winding mechanism 21 has a simple structure mechanically, but for the reasons described above, it is necessary to mount the slip mechanism and the recording paper winding diameter. When there is a large change in the take-up force and the take-up force changes greatly, there is a problem in that it is difficult to adjust the slip force in relation to paper feed.

[Explanation of Examples]

 Hereinafter, the recording paper winding mechanism in the printer device according to the present invention will be described in detail with reference to specific embodiments shown in the drawings. FIG. 1 is a schematic side view showing the basic structure of a recording paper winding mechanism in a printer device according to the present invention. In particular, FIG. 1A shows the winding state, and FIG. This shows the state in which the winding diameter has increased due to the progress of winding. In the example shown in this figure, the recording paper take-up mechanism 1 sends out the recorded recording papers C and S along preset recording paper feed lines F and L, and the recording paper feed lines F and L are fed. It is configured so as to be wound around a recording paper winding shaft provided in the above. Specifically, one rotary drive source 2 and a first rotary drive source 2 composed of a belt or the like are provided. A paper feed roller 4 mechanically interlocked via a power transmission means 3 is provided. By the paper feed roller 4, the recorded recording papers C and S are moved along the recording paper feed lines F and L. It is configured to send out. The paper feed roller 4 urges the recorded recording papers C and S on the recording paper feeding lines F and L toward the recorded recording papers C and S so as to apply a feeding force in the feeding direction. is there. On the other hand, in this invention, the recording paper take-up shaft 5 provided in the recording paper feed lines F and L is only a free rotary shaft that is rotatably fixed, and the recorded data is recorded around the shaft body. The paper C and S can be wound up.

In this invention, as a means for winding the recorded recording papers C and S on the recording paper winding shaft 5, a winding roller means 6 independent of the recording paper winding shaft 5 is used. Have The take-up roller means 6 includes a swing arm 8 pivotally supported by a pivot shaft 7 and a take-up roller pivotally supported by a swing end 8a of the swing arm 8. 9 and a second power transmission means 10 for mechanically interlocking connection between the take-up roller 9 and the rotational drive source 2 for rotationally driving the take-up roller 9. In the take-up roller means 6, the swing arm 8 is provided with a projecting arm 11 at the diametrically opposite end 8b of the swing end 8a with respect to the pivot 7, so that the projecting arm 11 and the machine body can be appropriately pulled in a pulling direction. The acting spring 12 is tensioned. In the structure of the take-up roller means 6, the take-up roller 9 makes a busbar contact with the outer peripheral surface of the recorded recording paper C / S wound around the recording paper take-up shaft 5 and passes through the take-up paper. In order to prevent the recording paper winding shaft 5 from rotating, the spring 12 biases the recording paper winding shaft 5 toward the recording paper winding shaft 5. In the example shown in the drawings, the second power transmission means 10 includes a first belt 10A mechanically interlockingly connecting the rotary drive source 2 and the pivot 7, and the pivot 7 and the winding. The second belt 10B mechanically interlocks with the rotation shaft 9A of the take-up roller 9. In this invention, the paper feed roller 4 and the take-up roller 9 need only rotate in the same direction in the example shown in the figure, and there is no need for synchronous rotation. Further, in the above embodiment, the rotation ratio between the paper feed roller 4 and the take-up roller 9 is such that the rotational peripheral speed of the take-up roller 9 is slightly higher than the rotational peripheral speed of the paper feed roller 4. You can set it as follows.

According to the recording paper winding mechanism in the printer device according to the present invention, when the recorded recording papers C and S are wound around the recording paper winding shaft 5, the recording paper winding shaft 5 is wound around the recording paper winding shaft 5. The recording paper winding shaft 5 is rotatably driven from the outer peripheral surface side by the winding roller 9 combined so as to come into contact with the outer peripheral surfaces of the recorded recording papers C and S, so that the recording paper winding The peripheral speed on the shaft 5 side and the winding force are constant, and stable winding can be performed without the need for a conventional slip ring mechanism.
