Description

[Detailed explanation of the idea]

0001

【Technical field】

The present invention relates to a passbook printing device, particularly a passbook printing device for a general-purpose financial counter terminal system. Regarding.

0002

[Prior art]

Conventionally, in this type of passbook printing device, the The amount of the deposit or refund will be automatically stamped on the recording side of the deposit passbook. It was written. This deposit passbook has a mount on which the impression of the deposit user's transaction seal is engraved. was affixed to the header of the passbook, and the mount was covered with a transparent sticker. . When updating your bankbook, the mount will be attached to the header section of your new bankbook. After that, I covered the mount with a transparent sticker.

0003 In this passbook printing device, as shown in FIG. The print head 18 is guided by the head shaft 19 and moves in the row direction. ing. The movement of the print head 18 is caused by the driving force of the motor 22 acting on the pulleys 17a and 17b. This is done by being transmitted to the print head drive belt 16 stretched between . That is, by rotating the pulley 17a directly connected to the motor 22, printing is performed. The head drive belt 16 moves in the row direction and is connected to the print head drive belt 16. The printed print head 18 is now moved in the row direction along the print head shaft 19. ing. When the print head 18 moves in the row direction, it simultaneously moves the paper guide 2. Printing is now possible on the recording surface of the bankbook inserted between 0 and platen 24. ing. Here, the drive shaft connecting the motor 22 and the pulley 17a is a bearing 23. It is pivoted on.

0004 In this case, the print head shaft 19 and platen 24 are fixed. The gap between the print head 18 and the platen 24 is kept constant. Here, mark Paper guide 2 is used for the writing surface of the bankbook, which is thick with the counter paper and transparent sticker. 0 and the platen 24.

[0005] When the print head 18 is moved in the row direction by the rotational drive of the motor 22, As shown in FIG. Characters are performed. However, when the print head 18 passes over the stamp mount 28, When the stamp mount 28 comes into contact with the paper guide 20, the paper guide 20 is bent. I'm going to lose it. At this time, the ink ribbon guided by the ribbon guides 25a and 25b The gap between the paper guide 26 and the paper guide 20 is also narrowed, and the paper guide 27 is now The link ribbon 26 will come into contact with them.

[0006] In such a conventional passbook printing device, there is a gap between the paper guide 20 and the platen 24. The gap is the total thickness of the recording surface 27a of the bankbook 27, the seal mount 28, and the transparent seal. Because the print head 18 passes over the stamp mount 28, , the part of the seal mount 28 contacts the paper guide 20 and bends the paper guide 20. Since the ink ribbon 26 comes into contact with the recording surface 27a of the bankbook 27, the recording surface There was a problem that 27a was contaminated.

[0007]

[Purpose of invention]

This invention was made to eliminate the problems of the conventional ones as mentioned above. The purpose of the present invention is to provide a passbook printing device capable of preventing dirt on the recording surface of a passbook.

[0008]

[Structure of the idea]

The passbook printing device according to the present invention is a passbook printing device that prints on passbooks using a print head. a printing device, which is movable in a direction perpendicular to the print surface of the print head; a variable platen; a biasing member that biases the variable platen toward the print head; The variable platen is moved in the row direction in synchronization with the movement of the printing head in the row direction. A driving means is provided.

[0009]

【Example】 Next, an embodiment of the present invention will be described with reference to the drawings.

0010 FIG. 1 is a plan view of an embodiment of the present invention. In the figure, the variable platen 1 is It is supported by the upper and lower shafts 2 and the platen base 4, and is It is biased toward the head 18 side. The platen base 4 is attached to the base part 21. The motor is guided by the platen shaft 5 and transmitted to the platen drive belt 6. It is adapted to move in the row direction by the driving force of 12.

[0011] The driving force of the motor 12 is transmitted to the gear shaft 9 via the gear 11 and the bevel gear 10. and is transmitted to the platen drive belt 6 stretched between the pulleys 7a and 7b. Ru. As a result, the platen drive belt 6 moves in the row direction, so the platen drive belt 6 moves in the row direction. The platen base 4 connected to the belt 6 is moved along the platen shaft 5 in the row direction. Moving. Therefore, the variable platen 1 supported by the platen base 4 is also moved in the row direction. move. Here, the gear shaft 9 is pivotally supported by a bearing 8.

0012 Further, the driving force of the motor 12 is transmitted to the gear shaft via the gear 11 and the bevel gear 13. 14 and stretched between pulleys 17a and 17b. is transmitted to port 16. This causes the print head drive belt 16 to move in the row direction. Therefore, the print head 18 connected to the print head drive belt 16 is connected to the print head system. It moves along the shaft 19 in the row direction. In other words, variable platen 1 and printing The heads 18 will each move synchronously in the same direction. Here, the gear shaft 14 is pivotally supported by a bearing 15.

[0013] The print head 18 is inserted between the variable platen 1 and the paper guide 20 When printing on the recording surface of a passbook (not shown), the variable platen 1 responds to the tension of the spring 3. Therefore, the printing impact of the print head 18 is increased by being biased toward the paper guide 20 side. accept.

[0014] When the motor 12 rotates, the gear 11 rotates and drives the bevel gears 10 and 13. . As a result, the driving force of the motor 12 is transmitted to the gear shafts 9, 14, and the pulley platen drive belt 6 and print head drive belt 1 via 7a and 17a, respectively. 6. Therefore, the variable platen 1 and the print head 18 are synchronously Move in the row direction.

[0015] Due to this movement in the row direction, the print head 18 is thickened by the seal mount and the transparent seal. When passing over the recording surface of a bankbook that is thick, it changes by the thickness of the bankbook. The platen 1 moves toward the platen base 4 against the urging force of the spring 3. Therefore, The paper guide 20 can be used to record a bankbook without being bent by the seal mount. The gap between the notebook and the paper guide 20 is always kept constant. This allows the printhead to The ink ribbon of the card 18 will not come into contact with the recording surface of the bankbook and stain it.

[0016] In this way, the variable head 18 is movable in the direction perpendicular to the printing surface of the print head 18. The platen 1 is urged toward the print head 18 by the spring 3, and the gear 11 and , bevel gears 10, 13, gear shafts 9, 14, and pulleys 7a, 17a. The motor 12 is connected to the platen drive belt 6 and the print head drive belt 16, respectively. Drive force is transmitted to synchronize the variable platen 1 and print head 18 in the same row direction. By moving the paper guide 20 between the recording surface of the bankbook and the paper guide 20. The gap can always be kept constant. Therefore, the print head 18 is connected to the stamp mount and the transparent sheet. Even when passing over the recording surface of a bankbook, which is thick due to the paper The guide 20 is not bent by the stamp mount and the print head 18 is The ink ribbon may come into contact with the recording surface of the bankbook and stain the recording surface. do not have.

[0017]

[Effect of the idea]

As explained above, according to the present invention, the direction perpendicular to the printing surface of the print head is The variable platen, which can be moved freely in the direction, is biased toward the print head, and the By moving the variable platen in the row direction in synchronization with the movement in the row direction. This has the effect of preventing stains on the recording surface of the bankbook.
