Abstract

PURPOSE:To improve the operability and cost of a printer by integrating a paper-feeding tractor to send continuous papers with a single slip inserter by providing a single slip inserter integrated with a paper presser for the tractor for supplying papers. CONSTITUTION:When using continuous papers, a single slip inserter 25 provided with paper feeding tractors 1 and 1' and a paper presser to pressingly put a continuous paper 11 into the tractors 1 and 1' is opened around pins 24 and 24' as the center. The claw of the tractor is coupled with the hole of the paper 11, and a single slip inserting part 18 is closed. When using single slip papers 3, a lock lever 21 to fix the tractors 1 and 1' is opened, and the single slip paper is matched with the size of a single slip to be used, moved on a fixed shaft 22, and fixed by the lever 21. In this case, a pinch roller 6 to be pressed by the platen 4 is in the opened state toward the direction of D by manual operation. A single slip is inserted into the opening 25a of a single slip inserter 25 serving as the continuous paper presser of the tractors 1 and 1' until it comes into contact with a paper pressing spring 23 fixed to the inserter 25, and the roller 6 is pressed on the platen 4 manually.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention supplies a long continuous sheet of paper using a tractor or sprocket type paper feeding mechanism, and further presses the cut sheet of paper against a platen using a pinch roller. The present invention relates to a printing device that prints characters using a needle, type, heat-sensitive, discharge, etc. print head.

Configuration of Conventional Example and Its Problems An example of printing using cut paper in a conventional printing device will be described with reference to FIGS. 1 and 2.

In Fig. 1, the paper feed extractor 1.1' has a ticket insertion device! 2.2' is installed, this ticket insertion device 2
．． The ticket 3 inserted through the opening 2' is pinched by a platen 4 and a pinch roller 6 supported by a shaft 6, and is ejected through a print head 8 that slides on a shaft T. .

The platen 4 is supported by a side plate 9,9', and a gear 10 whose rotation is transmitted from a drive source such as a motor is fixed to one end thereof. This gear 1o is the continuous paper 11
A square shaft 12 drives a paper feed tractor that feeds and supplies paper.
It meshes with a gear 13 fixed to and rotates synchronously. In FIGS. 1 and 2, 14 is a paper support member, 16 is a tractor drive shaft, 16 is a gear meshing with the gear 13, 17 is an ink ribbon cassette that moves together with the print head 8, and 18 is a continuous paper 11 and single paper. A paper guide plate 23 guides the slip 3 to the print head 8 side, this paper guide plate 1
A thin plate spring 19.20 is connected to the platen 4 to press the paper sent out from the paper guide plate 18 onto the platen 4, and a claw portion 19! L, 20!
an operating lever 19b for releasing L from the paper feed retractor portions 1 and 1';

2Qb is the part 190 connected to the ticket inserting device 2.2'
．． An elastic part 21 extending from 200 is a lock lever that fixes the tractor part in accordance with the paper widths of the continuous paper 11 and the cut sheets 3.

When using cut sheet paper '3, place the cut sheet inserting device 2.2' on the paper holding parts 12L, 1&' of the paper feed tractor 1.1', and press the claws provided on the cut sheet inserting devices 2, 2'. 192L, 2
11L is installed by hooking it onto the paper feed tractor 1.1', and adjust the width of the paper feed tractor 1,
1' in the axial direction of the sliding shaft 22, and lock lever 2
It is fixed by operating the ticket inserting device 2, 2'.
A cut sheet is inserted through the opening, wrapped around the platen 4, and is fed by rotating the platen 4 while being pressed by the pinch roller 6.

In addition, when using the continuous paper 11, the ticket inserting device 2.
2', move the lock release operation lever to arrow A,
By operating in direction B, the claws 19a, 21& are released from the paper feed tractors 1, 1', and in that state, the ticket insertion device 2.2' is removed from the paper feed tractors 1, 1'. .

Thereafter, the continuous paper 11 is inserted between the paper feed tractors 1, 1' and the paper pressers 11L, 11L', and the continuous paper is sent out by the tractor.

In other words, in such a conventional printing device, by attaching the ticket inserting device 2, 2' to the paper feed tractor section 1, 1' of the main body, it is possible to print on the ticket paper. However, since it is removable, it is necessary to attach and remove it depending on the paper being used, which is time-consuming and troublesome.In addition, since it is removable, there is a risk of losing it, and it also increases costs.

Purpose of the Invention The present invention aims to eliminate such conventional drawbacks, and to improve operability and cost by integrating a paper feed tractor and a ticket insertion device when feeding continuous paper. It is.

Structure of the Invention In order to achieve this object, the present invention provides a sheet feeding tractor section with a cut inserting member integrally molded with a paper pressing member.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. In FIGS. 3 and 4, the same parts as in FIGS. 1 and 2 are given the same numbers.

When using continuous paper, the paper feed tractors 1, 1' and the cut inserting member 26, which also serves as a paper presser for sandwiching the continuous paper 11 into the paper feed tractor 1.1', are opened around the pins 24, 24'. Then, the tractor pawl and the hole of the continuous paper 11 are fitted, and the slip insertion member 18 is closed. A gear 13 is fixed to one end of the shaft 12 that rotates the tractor.
is the gear 16 and platen 4 whose rotation is transmitted from the drive motor.
They mesh with a gear 1o fixed to one end of the gear, and rotate synchronously. The continuous paper 11 is fed out by such a mechanism. ``When using a cut sheet 3, the lock top/bar 21 fixing the paper feed retractor section 1.1' is released, moved, and fixed by the lock lever 21.

At this time, the pinch roller 6 pressed against the platen 4 is manually opened in the direction D.

Insert the ticket through the opening 25& of the ticket insertion member 25 which also serves as a continuous paper presser of the paper feed tractors 1, 1', and push it until it comes into contact with the paper presser spring 23 fixed to the ticket insertion member 26. , Then, the pinch roller 6 is manually pressed against the platen 4 side. Now, by rotating the platen 4, the cut sheet 3 that has been pinched by the platen 4 and the pinch roller 6 is sent out to the print head 8 side. Note that 26 is a spring that biases the ticket insertion member 25.

Effects of the Invention As described above, according to the ticket inserting device of the present invention, since it is integrated with the paper holding member of the serial sheet feeder 1-actor, it is easy to operate and there is no need to remove it, eliminating the risk of losing it. This has the effect that changes can be made without changing the conventional configuration.

FIG. 1 is a perspective view of a conventional printing device, FIG. 2 is a side view of a conventional ticket insertion device, FIG. 3 is a perspective view of a printing device according to an embodiment of the present invention, and FIG. 4 is a ticket insertion device. FIG. 3 is a side view of the device.
