The tip part is K so that it is integrated. It was,
The first feeder 5#i and the first detector 116 are rotated by a motor (not shown) by a motor that detects the leading end of the tape-shaped thermal paper 3. The first feed roller 5 is composed of a drive system row 55a and rollers 5h and K pressed against the drive system roller 56 by the biasing force of a spring 20. 9. The second feed roller 8 is composed of rollers 8h and 8k which are pressed against the four rollers 81 of the drive system and the rollers 81 of the second drive system by the biasing force of the spring 21. Furthermore, the cutter 9Fi is composed of a fixed blade 9@ and appropriate means KLfJ and movable blades 9h and K that reciprocate.

On the other hand, the first feed roller 5 marked with * is provided with a #i-mi one-way clutch function, and the first feed roller 5 is driven with a tarlatch connected only when 30 tape-shaped thermal papers are set. During printing, the tarlatch is cut off and rotated during printing. That is, during printing, only the #i*2 feed roller 8 is driven to convey the tape-shaped thermal paper 3, and the first feeding roller 5 works to convey the tape-shaped thermal paper 3.
It's called Klk, which rotates quickly during the middle rotation. Note that %22 is an L-shaped conveyance path through which the ticket P cut by the cutter 9 and printed with predetermined information by the thermal head 11 is conveyed to the discharge port 15. and a belt 25 driven by these rollers 24, and a fourth detector for detecting the end se of the tape-shaped thermal paper 3,
26 is a roller that guides the tape-shaped thermal paper 3 toward the guide path 4.

Next, a method of loading one tape-shaped thermal paper 3 will be explained.

First, the user picks up the leading end of the tape-shaped thermal paper 3 that has been wound into a roll around the winder 2 with the print side facing inside, and pulls it to insert it into the guide path 40 entrance portion 4eK. When the leading edge of the moving tape-like thermal paper 3 is detected by the first detector 6 due to this insertion, the feeder 5 of 1s1 is driven.
A tape-shaped thermal paper 3 is conveyed along a guide path 4. Then, when the tape-shaped thermal paper 3 is conveyed a predetermined amount and its leading edge is detected by the detector 7 of ts2, the feed roller 8 and platen roller 12- of IIE2 rotate, and this second feed 1+ --When the tape-shaped thermal paper 3 reaches the tip 8,
The tape-shaped thermal paper 3#i is conveyed by the second conveyance roller f3. When the sixth detector 10 detects the tip of the tape-like thermosensitive g3 during this conveyance, the feed t of 111E2 is detected.
J4-RA 8#i Tape-shaped thermal paper 6 is conveyed by about the autumn equinox and production is stopped. At this time, the leading end of the tape-shaped thermal paper 3 is held by the second feed roller 8 and the platen roller 12. At that time, dust cleaning member 2B#i ticket printing W
When the ticket comes into contact with the MK and the ticket is conveyed, the dust on the surface of the ticket is removed and the ticket enters the thermal head 11. After printing, the leading edge of the tape-shaped thermal paper 6 that has been retained (this leading edge is not normally shaped, so it cannot be used as a ticket P) is cut off. The cut portion is cut and shaped by the machine, and the cut portion is transferred to the transport path 22
After being transported by the gate 19, the vibrations are separated and taken into the collected seed box 1B. On the other hand, the tape-shaped thermal paper 3 whose tip has been shaped is transported by the amount of one coupon by the rotation of the second feed carots 8, and then the second feed)
It is placed between the roller 8 and the platen a-ra 12 and cut by the cutter 19. In other words, a fixed size ticket P
is set under the thermal head 110, which is a ticket standby snow cover, and waits for ticket issuance.

Upon receiving the printing command for the ticket sheet set as described above, the sheet is conveyed by the rotation of the platen roller 12, and at this time, predetermined items are printed by the swivel head 11, and then, On the other hand, when this ticket P is printed, the second feeder 1a-roller 8 is rotated again and the tape-shaped thermal paper 3 is is conveyed by a predetermined amount, and then cut by the cutter 9 and the next ticket P is set.

Thereafter, when printing commands are sequentially received, the tape-shaped thermal paper 6 is conveyed by a predetermined amount, but at this time, #! At c, the clutch of the first feed roller 5 is disengaged and rotates midway.

That is, only the tape-like heat sensitive t5 #i second power feeding area - ra 8 is transported from K! The first feed roller 5 is rotated by the tape-like thermal paper 5.

In this way, during printing, the first feed for conveying the tape-shaped thermal paper 6 by the drive foot of only the roller 8 in the #i second feed during printing does not require driving the I-roller 5, reducing labor consumption and consumption. can be reduced. In addition, the feed roller 8, the platen roller 12, the dust cleaning member 28 provided in the O-opening, the dust casting pressure cover 29 on the guide path 4, and the chips from the ticket paper due to the K cutter 19 are removed from the nail head 11. This is to prevent damage to the thermal head 110 when it is transported.

It should be noted that the above embodiment is merely an example, and it goes without saying that each member can be replaced with other members having the same function.
1. It goes without saying that it would be better to use other appropriate materials that have the same effect as the gauze cloth type, and suction devices in the brush, air blowers, etc. may also be used. In the case of H, it is difficult to remove the moldy dust, and in B, the stirrup becomes larger, which is a little difficult.

ζer＠Company With the structure described above, even if there is dust on the print surface of the thermal paper, by cleaning it before feeding it to the printing section, the print head can be protected and it will last for a long time. It can withstand many uses and can protect the printing condition well.
