The present invention relates to a head drive device of a deposit account printer that issues a deposit / payment statement to a depositor in the financial system. In particular, the head is fixed in accordance with the thickness of the printed surface that is varied according to the number of pages of the passbook. The present invention relates to a head drive device of a bankbook printer that can be aligned to maintain the spacing, and provides a uniform and stable shock absorbing power to provide excellent printing and prevent breakage of the head pin.

Various bankbook printers for organizing deposit bankbooks for depositing deposits / payments to be given to depositors have been developed and used to date, and such bankbook printers generally have a book-type bankbook containing at least one book. Spreading on a base consisting of two pairs of pairs of first feeders and second feeders which are installed in front and rear of the base, in a direction intersecting the feeding of the bankbook on the base between the first and second feeders. A desired print is achieved by a head provided in the carriage installed to be driven.

Such a bankbook printer prints a bookshelf through a bookcase in which several sheets of paper are collected, that is, prints a page after printing is completed and prints on a new page.

The thickness of the to-be-printed surface fed to the head side at the time of printing is changed while passing the bankbook thus fed.

In other words, the thickness is gradually increased according to the number of pages turned, and the head is also raised and lowered according to the height of the printed surface to perform the printing process.

By the way, the head position control configuration for raising and lowering the head in accordance with the change of the printed surface thickness of the passbook fed from the passbook printer, the suspended surface of the head by using the tension of the elastic member (spring) and the printed surface thickness of the passbook As the elastic member increases and decreases, the height of the head is adjusted or the height of the head is controlled by using a cam method.

However, in the height adjustment configuration of the head, the head height configuration using the tension of the elastic member physically forms the height of the head by the change in the tension length of the elastic member.

More specifically, the elastic member increases and decreases according to the thickness of the printed surface of the bankbook to be fed, and the height of the head is adjusted to the printed surface.

At this time, when the thickness of the printed surface is increased by increasing the number of printed sheets, the tension of the elastic member is gradually reduced to increase the height of the printed surface, that is, when the height of the printed surface is low and the tension of the elastic member is changed so that the head on the printed surface is changed. Since the height alignment position is greatly influenced by the tension degree of the elastic member, precise adjustment is not made, and thus, the spacing between the head and the printed surface cannot be uniformly maintained in accordance with the height change, resulting in uneven printing. In addition, when the tension of the elastic member is low, that is, when the thickness of the printed surface is increased and the elastic member is contracted, the tension of the elastic member is lowered and the shock absorption is poor when printing, causing frequent head breakage. The impact noise was large and product defects were not as reliable.

In addition, the height adjustment configuration of the head using the cam also allows the height of the head to be directly adjusted by the cam curve, which is also inaccurate and the gap between the printed surface and the head is not precise and the shock absorption of the head pin is poor. Not only was this falling problem, but there were also many defects such as complicated structure and increased device volume.

The present invention has been made in consideration of the above circumstances, and its object is to maintain the printing position of the head precisely and consistently according to the thickness change of the printed surface to be fed, and to achieve the printing state uniformly and clearly. The present invention is to provide a head drive device of the passbook printer that can prevent the breakage of the head pin by contacting the head to maintain the proper shock absorption to the printed surface.

The object of the present invention is to provide a headbook device for a bankbook printer that uses a depositbook printer that issues credits to depositors and records deposits / payments in the financial system, that is, a dot-type head that moves up and down on the platen. The head drive has a suspension that rotates about the rear end on the platen and lifts the carriage having the head integrally on the platen, and lifts the suspension by driving the control signal. It is configured to cooperate with the platform and the spring lifted by. The platform also includes a first shielding member for setting the lowering position of the platform and a first shielding plate for turning on and off the second sensing member for setting the elevated position of the platform, thereby printing the bankbook to be fed. The head is lowered first to the thickness of the surface and the platform is lowered again with the head reaching the printed surface. Secondly, the head is fixed to the printed surface by the tension of the spring mounted between the platform and the suspension platform. This is keeping it up.

Therefore, the head is constantly aligned with the thickness height of the printed surface to be fed and maintains an appropriate impact absorption force.

Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall side view of the passbook printer to which the head drive device of the present invention is applied, and the passbook to be pushed into the flat base 100 has two pairs of one set installed in the front and rear (left and right directions in the drawing). The first feeder 12 and the second feeder 130 of the feed / will be removed.

Then, the carriage 200 having the head 210 formed on the platen 110 is installed to perform the desired printing (see FIG. 4).

The present invention is a drive device for lowering and raising the head 210 on the platen 110, ie lowering and lifting the head 210 on the platen 110 during printing and non-printing of the passbook in the conventional printer configured as described above Is mounted.

As described above, the head 210 is integrally provided in the carriage 200 installed to be driven in a direction intersecting with the feeding / discharging of the passbook installed in parallel on the platen 110 to perform printing by a control signal. Will be performed.

In addition, as shown in FIGS. 3 and 4, a suspension stand 300 is installed on the frame 10 of the apparatus so as to be movable around the shaft pin 11, and the suspension stand 300 has a substantially c-shaped plate shape. Consists of

In addition, the first sensing member 710 to be described later is integrally fixed to the suspension stand 300 by fixing means such as bolts and nuts.

In addition, the suspension stand 300 is connected to the first shield plate 510 and the spring 600 of the lifting platform 500 which can be elevated by the lead screw 440 of the lift 400 mounted on the upper side of the main body to be described later. do.

The lift 400 is installed in a vertical direction as shown in FIG. 2 to perform a desired operation. The lift 400 is driven by a driving gear 420 with a rotational driving force of the driving motor 410. 430, the driven gear 430 rotates the lead screw 440 to elevate the platform 500.

The platform 500 is the first shielding plate 510 and the second shielding plate 520 having a substantially N-shape as shown in Figs. 1 and 2 are integrally fixed to the nut member 501 by fastening means. The nut member 501 is screwed to the lead screw 440 to move the spiral, so as to elevate the platform 500 as described above.

That is, when the lead screw 440 is rotated in the forward or reverse direction by the forward and reverse rotation of the drive motor 410, the platform 500 is guided to the lead screw 440 to go up and down a predetermined distance.

Further, as shown in FIGS. 1 and 4, the platform 500 is connected to each other by the suspension 300 and the spring 600 which are movable around the shaft pin 11, and the spring 600 is connected to the platform ( The 500 may absorb mutual shocks during the elevation and compensate the gap between the head 210 of the carriage 200 and the passbook.

The lifting and lowering of the platform 500 lifts the carriage 200 on the platen 110 and pushes the carrier head 210 off and on to the printed surface.

On the other hand, the platform 500 is additionally provided with a control structure for setting the up and down position of the carriage 200, that is, the top dead center and the bottom dead center of the head.

The control structure of the platform 500 is a top dead center of the first sensing member 710 and the head to set the bottom dead center of the head on the upper and lower sides of the appropriate position, that is, the lifting platform 500, the outer wall surface of the frame 10. It is provided with a second sensing member 720 for detecting the setting.

Among the first and second sensing members 710 and 720, the first sensing member 710 is fixedly movable to be integral with the movable suspension 300 which is movable around the shaft pin 11 as described above. It is.

The second sensing member 720 is fixed on the frame 10 of the main body at the position where the second shield plate 520 of the lifting table 500 is elevated, as shown in 4a, b, c, and the carriage 200. The head 210 of the printing is finished to control the upward movement position.

Referring to the operation of the head drive device of the present invention configured as described above in detail as follows.

4A illustrates a state in which the head 210 of the carriage 200 is raised to the highest position.

This position is a state before the feeding of the passbook 20 to be printed or the state in which the head 210 of the carriage 200 is separated from the printed surface of the passbook in order to perform feeding and removal of the passbook after printing.

At this time, the first shielding plate 510 and the second shielding plate 520 of the platform 500 are located in each of the first sensing member 710 and the second sensing member 720 and are in an off state.

In this state, when the passbook 20 is fed onto the base 100 to align the print rows, an output signal for lowering the head from the control device is given.

In response to the output signal, the driving motor 410 of the lift 400 starts driving to rotate the lead screw 440 to lower the platform 500.

When the lifting platform 500 begins to descend, the suspension platform 300 is connected to the spring 600 and the lowering of the platform 500 continues as the spring 600 is elongated and at the same time the extension of the spring 600 and In addition, the suspension stand 300 also flows about the shaft pin 11 and moves downward as shown in FIG. 4b.

When the suspension stand 300 descends together with the lift table 500 and the head 210 of the carriage 200 contacts the printed surface of the bank 20 as shown in FIG. At the same time, the suspension platform 300 that descended along the platform 500 stops descending. The alignment of the head position causes the head to be constantly brought into contact with the printed surface in accordance with the height of the printed surface thickness of the passbook 20 to be fed.

At this time, even after the head 210 is aligned in contact with the surface to be printed, the driving motor 410 continues to drive without stopping and continues to lower the platform 500, but the suspension having the head 210 aligned to a predetermined position. Base 300 no longer descends. In other words, the spring 600 connecting the lift table 500 and the suspension stand 300 is extended to offset the lowering force so that the lowering force of the lift table 500 is not transmitted to the suspension stand 300 side.

As described above, the lowering of the platform 500 is, as the first detection plate 510 of the platform 500 is eventually separated between the first sensing member 710 fixed to the suspension 300, the first sensing member 710 is turned on from the off state to stop the drive motor 401.

As described above, the lift table 500 extends the spring 600 connected to the suspension stand 300 by further descending as shown in FIG. 4C even when the suspension stand 300 is aligned to a predetermined position. Elongation) acts to absorb the pin shock of the head 210 applied to the printed surface, that is, the impact of the printing head pin strike.

That is, the expansion of the spring 600 is made after the alignment of the head position to always compensate for the shock with a uniform elastic force corresponding to the thickness height of the printed surface to be fed.

Next, after the completion of the desired printing on the printed surface of the passbook (after the last column printing) in the state as shown in FIG. 4C, when the print completion signal is given, the driving motor 410 performs reverse rotation driving, and the driving mo The lifting platform 500 is raised by the rotation of the lead screw 440 connected to the rotor 410.

At this time, when the platform 500 rises, the spring 600 that has been extended is restored and contracted so that the lifting force of the platform 500 is transmitted to the suspension stand 300 through the spring 600 to push the suspension stand 300. Raised.

When the platform 500 is raised as described above and the second shield plate 520 below the platform 500 is positioned between the second sensing members 720, the second sensing members 720 are turned off. The driving motor 410 that raises the platform 500 by the off signal is stopped.

At this time, the platform 500 is raised to the highest position and restored to the position of Figure 4a to wait for the next print signal.

Therefore, the present invention is fed and physically aligned with the head 210 as the primary lift 400 according to the thickness of the printed surface of the passbook, and after the head is aligned with the printed surface, the secondary of the lift 400 is secondary. The spring 600 makes it possible to completely prevent the case that the head pin is broken by the impact impact by virtue of the accurate factor at a constant and stable hitting distance by maintaining the proper impact absorbing force on the printed surface by the tension force. will be.

In addition, the present invention has the advantage of miniaturizing the volume of the device by driving the head with a simple structure.

As described above, an embodiment of the present invention has been described, but the present invention is not limited thereto and may be changed within the scope of the claims.
