破損する欠点があつた。 A recording device that uses rolled recording paper has a recording section and a cutting section, but since these two sections are quite far apart, a non-recorded section (hereinafter simply referred to as a margin) occurs that corresponds to the length between them. It is uneconomical.
Therefore, in recording apparatuses that use rolled recording paper, there is a constant need to prevent the occurrence of blank spaces. Conventionally known methods for preventing the occurrence of blank spaces include a method of reversing the first drive source (means) as described in Japanese Patent Publication No. 53-34690, and a method of reversing the first drive source (means) using a cutting means. There are human methods. However, the latter method has the disadvantage that the device may be damaged if it receives driving forces from the first and second driving means simultaneously.

Ｃの方向へ移動しイニシヤル位置へ戻る。 Now, when a series of recording operations have been completed and the recording paper 29 has been fed to the cutting position, a cutting instruction is received from a control circuit (not shown), and a one-turn clutch, also not shown, is activated. The recording paper 29 is cut by receiving the driving force from the second driving means. The rotary blade shaft 5' is driven one rotation, and the idler cam gear 11 meshing with the cutter gear 12 is therefore driven. The idle cam gear 11 has its cam portion 11'
moves in the direction of arrow C along the cam line shown in FIG. 4, and eventually meshes with the rear roller reversing gear 10 to drive it. Rear roller reverse gear 10
is the back roller pulley 9 due to the frictional force with the friction member 19.
is rotated in a direction (hereinafter simply referred to as reverse rotation) opposite to the direction of rotation by the pulse motor 1 of the first drive means (hereinafter simply referred to as forward rotation). This rotation causes the drive roller 2 to reverse rotation via the second transmission belt 15. As a result, the recording paper 29 is returned in the direction of arrow B. At this time, the pulse motor 1 of the first driving means is also reversely rotated by the first transmission belt 14. The idle cam gear 11 is in the initial position with the cam boss 17 at the O position as shown in FIG. When the idle cam gear 11 receives a driving force, O
-W-X 1 , X 2 -Move in the direction of arrow C along the diagram of Y-Z-O and return to the initial position.

ーラ逆転歯車１０と噛み合わない様にしてある。 The cutting operation of the recording paper 29 by the cutting means is completed between O and W, and at the W position, the idle cam gear 11 is moved in the direction of arrow C by the force of the compression spring 21 and engages with the rear roller reversing gear 10 W-X. 1 , X 2 -Y, the driving roller 2 is rotated in the reverse direction while continuing the engaged state. This amount of rotation matches the amount of return required for the recording paper 29. During Y-Z, the idle cam gear 11 is moved in the direction of arrow D and returns to the initial position. The gear of the idle cam gear 11 is removed by an amount corresponding to the Y-Z-O interval so that it does not mesh with the back roller reversing gear 10 during that time.

る。 The first drive means and the second drive means are controlled by a control circuit (not shown) so that they do not operate at the same time, but even if they operate at the same time, the device is not damaged. Do not directly connect the back roller pulley 9 and the back roller reversing gear 10,
Frictional transmission is performed via the friction member 19. Therefore, when the back roller reversing gear 10 is driven by the pulse motor 1 while the drive roller 2 and the back roller 3 are rotating normally, the back roller reversing gear 10 slips with the friction member 19. The rotation is not transmitted to the back roller pulley 9. For this reason, the recording paper continues to be fed by the pulse motor 1.
Furthermore, the cutting means also returns to its initial position after completing one normal rotation, thereby preventing damage to the device.

面の面取りをすると効果がある。 The torque transmitted between the back roller reversing gear 10 and the friction member 19 is adjusted in advance to a magnitude necessary for normal reversing, but smaller than the driving torque of the pulse motor 1. In addition, in order to ensure smooth meshing between the idle cam gear 11 and the back roller reversing gear 10, the center distance between the two gears must be increased beyond the normal value, or the gears may be shifted in a negative direction to ensure that the gears mesh smoothly. It is effective to increase the number of teeth or chamfer the mating surfaces.

ことは避けられない。 FIG. 3 shows a reversing mechanism using a friction wheel transmission instead of the gear transmission used in the embodiments of FIGS. 1 and 2. FIG. The back roller pulley 9 and the back roller reversing roller 101 are integrally constructed and are attached to the back roller shaft 3' via a one-way clutch (not shown). The back roller reversing roller 101 is made of rubber material. The idler cam gear 11 and the friction roller 102 are integrally constructed, and the friction roller is made of a metal material. Other aspects are the same as in the case of gear transmission. When the idle cam gear 11 is now driven, it is moved in the direction of the arrow C as described above, and the friction roller 102 is brought into pressure contact with the back roller reversing roller 101. Therefore, the back roller reversing roller 102 is driven by frictional force to reverse the back roller pulley 9. The torque transmitted by the frictional force can be adjusted by the force of the compression spring 21. The torque transmitted by the frictional force between the back roller reversing roller 101 and the friction roller 102 is normally adjusted in advance so that it is of a magnitude necessary for reversing and smaller than the drive torque of the pulse motor 1. If this method is used, the torque transmission means and recording paper cutting means can be operated by the same mechanism, making it cheaper, but it is inevitable that the accuracy of the return amount will be inferior to the gear transmission method. .
