Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bankbook printing machine, and more particularly to a platen mechanism in a dot matrix printing machine used in a bank teller machine to print on a left-right opening bankbook.

Wire Dot Mato IJ is used as a printing machine for bank teller equipment.
A printing machine using a box is used. In this printing machine,
As the printing speed increases, the operating stroke of the printing element (type or wire), that is, the amount of movement up to the printing paper surface, decreases, and in order to obtain good printing, it is necessary to reduce the distance between the printing element and the printing paper surface. It needs to be kept small and constant. A secondary printing machine has a reference guide (which serves as a reference surface) placed in front of a printing mechanism section (hereinafter referred to as print head) consisting of printing elements, etc., at a certain distance from the tip of the print head. A platen (hereinafter referred to as a reference guide) is provided, and the printing paper is pressed against the reference guide using a platen from behind the printing paper. Printing machines used in bank teller equipment to print on bankbooks, etc., print on paper with different thicknesses for the left and right pages, even though the lines are printed on the same line, as in a bankbook with left and right openings. Printing is required. In such a bankbook printing machine, it is difficult to effectively and appropriately press bankbooks with different paper thicknesses on the left and right sides against the reference guide using the same Okayama platen.
To solve this problem, usually 2 or 3 platens are used.
A known platen mechanism is divided into the above parts and effectively presses the reference guide according to the thickness of the left and right sheets. However, such a conventional platen mechanism has a structure in which a plurality of divided platens are simultaneously moved to press the bankbook against the reference side from the back side thereof, and this has the following drawbacks. FIG. 2 is an explanatory diagram of the operation of the conventional mechanism when the platen is divided into three parts including the seam of the bankbook.

In Fig. 2A, the platen is divided into three parts la, lb,
lc is simultaneously driven and pushed forward. At the exit of Figure 2, the platen in the middle hits the back of the fold of the bankbook 10 with left and right openings. In Fig. 2C, the platen is still driven forward, but since the middle platen has resistance from the back mountain, the left and right platens are pushed forward and come into contact with the bankbook. Once the left and right platens come into contact with the passbook, the passbook will no longer be able to move left or right and escape, so it will no longer be possible to use the middle platen to push open the folds and force the standard guide. In FIG. 2, the operation ends with the left and right platens pressing the passbook against the reference guide. At this time, the folds of the middle platen will not be completely pushed open. As described above according to the operation diagram,
In the conventional technique of pushing out the split platens at the same time, the fold of the passbook cannot be completely pushed open, so the left and right pages are fixed in a state closer to the fold, and printing is performed. Therefore, there is a drawback that the printing position on the passbook is shifted left and right. An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, and to have the effect that the folds of a left-right open bankbook can be completely pushed open to bring the bankbook into close contact with the platen, and there is no misalignment of the left and right printing positions. Our goal is to provide passbook printing machines. The present invention is characterized by a passbook printing machine having a mechanism for pressing a passbook against a reference guide using a platen divided into two or three or more parts for printing on left-right open passbooks. Instead of using platens at the same time, one split platen can be used for one passbook.
With the divided platen positioned, the divided platen is moved in a predetermined order so that the adjacent divided platen positions the other part of the passbook, and the passbook is pressed against the reference guide.
The reason is that the fold of the passbook is configured so that it is completely pushed open.

Next, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a platen mechanism portion of a passbook printing machine showing an embodiment of the present invention. 1 is a platen, and the platen 1 is divided into three parts (la, la,
lb, lc).

2a. 2b and 2c are the divided platens la and l, respectively.
b, plate attached to the rear of lc, 3a, 3b,
3c is a stud attached to the plates 2a, 2b, 2c; 4a, 4b, 4c are magnets for pushing out the platens la, lb, lc in the direction of the reference guide 6; 5a, 5
b, 5c are recovery springs for platens la, lb, lc.

6 is a reference guide when pressing the passbook 10, and 7 is a guide for the passbook 10.

8 is a magnet drive circuit, and 9 is a control circuit.

The platen 1 is separated from the reference guide 6 via the plate 2 and the stud 3 by the force of the recovery spring 5.

In this state, when the left-right opening bankbook 10 passes in front of the platen 1 and is guided between the reference guide 6 and the guide 7, the drive circuit 8 is activated by a command from the control unit 9, and the magnet 4 is activated. Excited. When the magnet 4 is excited, the platen 1 is pushed out toward the reference guide 6 via the stud 3 and plate 2 against the force of the spring 5.
The pushed out platen 1 presses the left-right open bankbook 10 against the reference guide 6, so that printing is performed while maintaining a predetermined distance between the printing head (not shown) and the left-right open bankbook 10. FIG. 3 shows the movement of the divided platen of the platen mechanism of the present invention.

In this embodiment, divided platens la, lb, lc
are operated in order from the end. That is, in the embodiment shown in FIG. 1, the divided platens la, lb, and lc have driving magnets 4a, 4b7, and 4c, respectively, and can be driven independently under the control of the control section 9. It is possible to operate the wind blower. Of course, the driving source is not limited to magnets. As another example, using one driving source, the platens Ia and lb can be mechanically driven by other mechanisms corresponding to the plate 2 and the stud 3.
, lc can be moved sequentially from the end. By operating one division platen in this way and then operating the adjacent division platens in sequence, it becomes possible to completely push open the passbook fold, as shown in the operation explanatory diagram in Figure 3. .

That is, as shown in FIG.
0 is guided to the front of platens la, lb, and lc. Next, as shown in FIG.
to press against. Next, as shown in Figure 3', the platen l
b is pushed forward and pushes out the back mountain of the fold of the bankbook 10 that opens left and right. One page of the left-right opening bankbook 10 is already on the platen l
a is pressed against the reference guide 6, but the other page is not pressed yet and is free.
Therefore, when the spine of the fold is pushed by the platen lb, the left-right opening bankbook 10 can move toward the pages that are not yet pressed against the reference guide 6, so that the bankbook fold is completely pushed open and the reference guide 6 can be imposed on. Finally, as shown in FIG. 3 2, the platen lc is pushed forward with the passbook folds pushed open, and the remaining pages that have not yet been pressed against the reference guide 6 are transferred to the reference guide 6.
It will be forced on you. Although the above embodiment describes an example in which the platen 1 is divided into three parts, the present invention is not limited to this. As described above, according to the present invention, by sequentially operating the split platen at different times, the left and right opening bankbook 10
It is possible to completely push open the fold and press it against the reference guide 6, and it is possible to obtain the effect that the printing position on the passbook does not shift from side to side.
