The above-mentioned switch for detecting the presence or absence of the above-mentioned continuous paper is attached to this form trailing guide, and this switch is in pressure contact with the continuous paper when the above-mentioned continuous paper is being fed, and when it is not being fed. The present invention is characterized in that it has a lever positioned facing from the window at a position 1a with a slight clearance from the ticket rear guide.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described based on the drawings.

As shown in FIGS. 1 and 2, in the printer, a print head 1 is fixed to a carriage 2 on the front side of a platen 5 (on the left side in the figure). Carriage 2 has two rails 3
and 4 (not shown), and can reciprocate in the axial direction of the platen 5. During the reciprocating movement of the carriage 2, the print head 1 moves the ink ribbon (not shown) stored in the ribbon cassette 6. Printing is performed on continuous paper 17 (shown in FIG. 1) and cut sheet 22 (shown in FIG. 2) through the printer. Above the platen 5, a tractor 7 for feeding continuous paper 17 is rotatably supported on the printer body, and a front inserter 8 for feeding/inputting single sheets 22 is attached to a frame (not shown) of the tractor 7 device. ing.

Below the platen 5, a paper guide 9 is fixed to the printer base 10 with screws. The paper guide 9 includes a cut front guide 11, an opening/closing guide 12 rotatably supported on the cut front guide 11, and a cut rear guide 13 arranged at a predetermined distance from the cut front guide 11. Then, a form front guide 14 is arranged at a distance slightly wider than the operating range of a lever 19 of a switch 18, which will be described later, on the single form rear guide 13, and a form rear guide 15 is arranged on the form front guide 14 at a predetermined interval. It consists of A switch 18 for detecting the presence or absence of continuous slip paper is screwed and fixed to a mounting portion 16 of the silver slip rear guide 15 that is integrally formed with the slip rear guide 15. Further, as shown in FIG. 3, the form front guide 14 is formed with a window 20 through which the lever 19 of the switch 18 can be moved in and out. 1
