JPH04323150A - Sheet transfer path and sheet double face printing device - Google Patents

Abstract

PURPOSE:To obtain a sheet transfer path and a sheet double face printing device for printing on both sides of a sheet by providing a transfer path for reversing the front side to the rear of the sheet at the rear of a printing mechanism, in a sheet printing device in which the sheet passes through the transfer path and into the printing device for printing. CONSTITUTION:This device is provided with a first transfer path 5 comprising a printing mechanism, in which a printing head 1, a platen 2, and an ink ribbon 3 are incorporated, and a sensor 4 for confirming the top and rear ends of a sheet and a second transfer path 6 comprising a switchover valve 7 for reversing the sheet from the front side to the rear and a drive part 8. The sheet is printed by the printing mechanism, fed to the first transfer path 5, and its top end is confirmed by the sensor 4. Then the switchover valve 7 is raised upward to feed the sheet to the second transfer path 6. Also, when the sensor 4 confirms the rear end of the sheet, the switchover valve 7 lowers down to reverse the sheet from the front side to the rear after the sheet runs one round by the drive part 8 comprising a drive pulley 9a, a pulley 9b, and a belt 10. Then it passes through the first transfer path 5 and into the printing mechanism, and printing is made on its rear surface.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a ticket printing device.
In particular, the present invention relates to a ticket printing device that requires printing on both sides of a ticket.

0002

2. Description of the Related Art Conventional ticket printing devices print only on one side of a ticket, and do not have a mechanism for printing on both sides.

0003

[Problems to be Solved by the Invention] As mentioned above, in the conventional ticket printing device, the conveyance path ends at the printing mechanism section and it does not have a mechanism for printing on both sides, so it can only print on one side of the ticket. There is a drawback.

An object of the present invention is to provide a conveyance path at the rear of the printing mechanism section for turning the ticket from the front side to the back side.
It is an object of the present invention to provide a cut conveyance path and a double-sided printing device for a cut, which can eliminate the above-mentioned drawbacks and print on both sides of a cut.

[0005]

[Means for Solving the Problems] The ticket conveyance path of the first invention includes a switching valve that switches between inserting and discharging the ticket, and a switching valve that goes around the inserted ticket so that the surface of the ticket is reversed. It has a driving part consisting of a turning pulley and a belt, and the driving part discharges the sheet whose surface has been turned over by switching the valve of the switching valve.

[0006] A double-sided printing device for a ticket according to the second invention is a ticket printing device that sends a ticket through a conveyance path to a printing mechanism section and prints the ticket. It has a second conveyance path for feeding.

[0007] A double-sided printing device for a ticket according to a third invention is a double-sided printing device for a ticket according to the second invention, which has the ticket transportation path according to the first invention in the second transportation path. ing.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a side view of a double-sided printing device for a ticket according to an embodiment of the present invention, and FIG. 2 shows an operation of switching the front side (printed surface) of a ticket to the back side of the double-sided printing device for a ticket shown in FIG. Figure shown, Figure 2
(a) to (b) are diagrams showing each operation on the conveyance path of the cut sheet.

In FIG. 1, the double-sided printing device for a ticket according to the present embodiment includes a printing mechanism section having a print head 1, a platen 2, and an ink ribbon 3 for printing on a ticket, and a printing mechanism section for printing on a ticket. It has a sensor 4 for checking, a first conveyance path 5 up to the sensor 4, and a second conveyance path 6 consisting of a switching valve 7 and a drive unit 8 for turning the ticket from the front side to the back side. are doing. Further, the drive unit 8 includes a drive pool 9a and a pulley 9.
b and a belt 10.

Then, as shown in FIGS. 2(a) and 2(b), the ticket is printed in a printing mechanism section having a print head 1, a platen 2, and an ink ribbon 3, and is sent to a first conveyance path 5. When the tip of the ticket is confirmed by the sensor 4, the switching valve 7 is lifted upward and the ticket is sent to the second conveyance path 6.

Furthermore, when the sensor 4 confirms the rear end of the ticket, the switching valve 7 moves downward, and the ticket is moved within the second conveyance path 6 by a drive section 8 consisting of a drive pool 9a, a pulley 9b, and a belt 10. Once around, the front side turns over to the back side, and the first conveyance path 5
The paper is sent to the printing mechanism, where the back side is printed.

[0013]

As explained above, the double-sided printing device of the present invention is capable of printing double-sided tickets by having a conveyance path at the rear of the printing mechanism for flipping the ticket from the front side to the back side. This has the effect of making it possible.

[Brief explanation of drawings]

FIG. 1 is a side view of a double-sided printing device for a single sheet according to an embodiment of the present invention.

2 is a diagram showing an operation of switching the front side (printed side) of a ticket to the back side of the ticket double-sided printing device of FIG. 1; FIG. Figure 2(a)
-(b) are diagrams showing each operation on the conveyance path of the ticket.
