Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thermal printing device capable of printing fixed item information and variable item information on printing paper such as a coupon ticket.

Recently, there has been a desire to develop an automatic ticket gate with a ticket function.

In this automatic ticket gate, it is necessary to print fixed item information such as the station name and variable item information such as the date on the ticket that is inserted through the ticket slot and taken in and transported. However, when fixed item information and variable item information are printed in a subsidiary, they are printed separately using printing devices installed at different positions in a ticket vending machine or the like. Therefore, if the printing device is
This increases installation space, increases costs, and requires the ticket to be stopped twice, slowing down the printing process speed. The problem is that it cannot be applied as is. The present invention has been made based on the above-mentioned circumstances, and its object is to be able to reliably and quickly print fixed item information and variable item information at predetermined positions on guard-like printing paper, and to avoid misalignment of printing positions. It is an object of the present invention to provide a thermal printing device that can prevent this.

The present invention will be described below based on an illustrated embodiment.

In the figure, reference numeral 1 denotes a V thermal printing device located in the middle of a ticket paper transport path 2, which is a paper transport path formed in an automatic ticket gate with a ticket function. P
The station name 3 as fixed item information and the date 4 as variable item information are printed at the same time. A pair of conveyor belts 5, 5,
6, 6 are stretched so that the ticket P is held at both ends in the width direction and forcibly conveyed, and the heating printing device 1 is installed upright along one side edge of the ticket paper transfer path 2. It is attached to the front of the frame 7.

That is, on the front surface of the frame 7, there is a component support 8 having a lower horizontal support piece 8a extending to the lower surface side of the ticket paper transfer path 2 and an upper horizontal support piece 8b extending to the upper surface side of the ticket paper transfer path 2. It is attached via set screws 9...-. A stamp stand 10 is attached to the upper surface side of the lower horizontal support piece 8a of the component supporter 8 so as to be able to support the lower surface of the ticket P. Above the stamp stand 10, the station name 3 and date 4 are written. A heating printing plate head 11 and a thermal head 12 for printing are provided. The stamp stand 10 is placed along the ticket transfer path 2*
The notch is tapered to gradually approach the paper transport path.
Further, the heating printing plate head 11 and the thermal head 12 are supported movably so as to be able to move up and down using a pair of guide rods 13, 13 hanging down from the bottom surface of the base of the upper horizontal support piece 8b of the component support 8 as guides. Screws 15, 15 on body 14
have been defeated through each.

Also, the movable support body 14 is urged upward by return springs 17, 17 which are externally connected to the guide shafts 13, 13 and whose downward movement is regulated by stop rings 16, 16, so that both heads 11, 12 can be printed. The surfaces 11a and 12a are configured to be separated from the ticket transfer path 2. Further, a bushing magnet 18 is attached to the upper surface of the upper horizontal support piece 8b of the component support body 8, and this plunger 18a receives a pressing force that is horizontally projected from the center of the upper end of the movable support body 14. The movable support body 14 is returned to the springs 17 and 17 so that the lower end faces are opposite to the upper faces, and the printing surfaces 11 and 12a of both heads 11 and 12 are in contact with the coupon P.
The structure is such that it can be laid down against the urging force of. A movable support actuating mechanism 19 is configured to displace the movable support 14 in synchronization with the print signal. The heating printing plate head 11 is constructed as shown in FIGS. 4 and 5 in groups. That is, a cartridge heater 21 is iron-filled in the center of a cylindrical heating printing plate 20 having a printing surface 11a, and the heating printing plate 20 is iron-filled in a case 23 with a heat insulating material 22 interposed. ing. Further, a rectangular thermistor 25 is inserted into a notch groove 24 formed on the outer circumference of the heating printing plate 20 along the axis 0 direction.

Further, the cartridge heater 21 is fixed by a set screw 26 screwed into the heat dissipation printing plate 2M, and the heating printing plate 20
is fixed by a set screw 27 screwed into the case 22. Further, the thermistor 25 is fixed in close contact with the heating printing plate 201 by a set screw 29 screwed into the heat insulating material 22 through a screw insertion hole 28 formed in the case 23. On the lower end surface of the heating printing plate 20, as shown in FIG. 5, the station name 30 of "Kawasaki 1st class" is stamped in seal letters. Also, on the printing surface 12a of the thermal head 12, as shown in FIG. 7 segments as "day"
Heat-generating printing blocks 31 are arranged in a square shape.

Note that 32 shown in FIGS. 1 and 2 is a ticket transport stop located between the transport belts 6, 6 of the ticket transport path 2 and protruding freely into the ticket transport path 2. It is a stopper as a mechanism.

Thus, the ticket P inserted into the ticket slot of the automatic ticket gate is deposited into the ticket transport path 2 and conveyed by the conveyor belts 5, 5, 6.
, 6, and the stopper 32 protrudes into the ticket transfer path 2 in response to a ticket passage signal from a ticket passage detector (not shown).

Therefore, the conveyed coupon P comes into contact with the stopper 32 and is forcibly stopped with slippage occurring between the conveyor belts 5, 5, 6, and 6. On the other hand, in the thermal printing apparatus 1, the bushing magnet 18 of the movable body actuating mechanism 19 operates in synchronization with the printing signal to return the movable support body 14 and push it down against the biasing force of the springs 17, 17.

And the heating printing plate head 1 1 attached to the movable support 14
The printed surfaces 11a and 12a of the thermal head 12 are pressed against the ticket P at the same time, and the station name 3 and date 4 are printed on the ticket P at the same time. Then, the excitation of the push magnet 18 is released and the movable support body 14 is raised by the biasing force of the return springs 17, 17, and the stopper 32 is lowered, so that the coupon P is conveyed. ．．
The printing conditions are based on the voltage and time applied to the seven segments constituting the heat-generating print block 31 disposed on the printing surface 12a of the thermal head 12, the stop time of the ticket P, the head pressure contact time, and the printing stand. The material of 10 and the surface temperature of the printing surface of the heating printing plate 20 are set.

In addition, the surface temperature of the heating printing plate 20 in the heating printing plate head 11 is set to 120 to 15 pm using a heater 21 of several watts.
The temperature is controlled by 1°C by controlling the phase. In the above-mentioned embodiment, the case where the present invention is applied to an automatic ticket gate with a ticket function has been described, but the present invention is not limited to this, and may be applied to various ticket issuing machines, for example, and in short, it can be applied to fixed items. Any device may be used as long as it is necessary to print the information and variable item information on the face of the ticket.

It goes without saying that various other modifications can be made without changing the gist of the present invention. As described above, according to the present invention, fixed item information and variable item information can be printed simultaneously, and the print processing speed is improved compared to the conventional method in which each item is printed separately.

In addition, a stopper is provided at the rear end of the paper transport path than the printing stamp stand to determine the printing position from the front end of the paper, and this stopper and a belt that clamps and transports both ends of the paper in the transverse direction It also has the effect of preventing misalignment of the printing position and ensuring printing at a predetermined position. Also,
Since the stamp stand 10 is tapered to gradually approach the ticket paper transfer path along the ticket paper transfer path 2, even if the set of tickets is transferred in a undone state, it is smoothly guided onto the stamp stand 10 along the taper. This makes it possible to reliably prevent paper tickets from jamming.
