The present invention relates to a passbook printing device for printing data on bankbooks, forms, etc. (hereinafter referred to as "bankbooks"), and particularly suitable for automatically turning pages. It relates to a printing device.

An apparatus of this type is described, for example, in Japanese Laid-Open Utility Model Publication No. 55-66173.

In the above-described conventional apparatus, the force required to turn over the pages of the bankbook is dependent on the reaction force of the pressing bar that presses the bankbook against the page-turning roller and the friction force between the pages to be turned over and the page turning roller. Is formed by. The push rod itself is not equipped with any device for fixing the passbook. While turning the page, the rotation of the conveying rollers is stopped to lock the passbook in place.

The conventional apparatus has the following disadvantages. The relationship between the amount of deformation of the page turning roller and the force exerted by it does not correspond to a change in the thickness of the passbooks which may have different page numbers. Thus, the need for a driving device for driving the above-mentioned push rods and the push rods and other associated members makes the apparatus structurally complicated and expensive. Another disadvantage of the conventional apparatus is that, in the case of an imbalance between the force of the conveyance roller holding the account and the force of turning the page, the passbook may be moved or inclined by the rotation of the page turning roller.

It is an object of the present invention to solve the aforementioned problems of the prior art.

Another object of the present invention is to enable page turning to be reliably implemented by the passbook printing device.

In order to achieve the above objects, the passbook printing apparatus according to the present invention comprises a printing section and a passbook page turning mechanism, the passbook page turning mechanism having a page turning roller. The page turning roller of the apparatus of the present invention includes a member formed of an elastic material having a large friction coefficient and a small change in pressure with respect to a change in deformation amount, and the page turning operation is achieved by a force following only a change in pressure of the member. .

In one aspect of the present invention, there is provided a passbook printing device comprising a printing unit and a bankbook page turn mechanism, wherein the bankbook page turn mechanism has a page turn roller. The passbook page turn mechanism of the apparatus of the present invention also has a pad formed of a material having a high coefficient of friction and disposed at a position opposite to the page turn roller.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 1 shows a passbook factor device 10 according to a first embodiment of the present invention. The apparatus 10 includes an inserter 2 for inserting a passbook (abbreviated as "bankbook") 1, a plurality of conveying roller pairs 3a to 3d, a magnetic head 4, a printing head ( 5), a page turning roller 9 and a detector 15. The magnetic head 4 reads the information recorded on the magnetic stream 1a provided on the cover of the bankbook 1 and writes the information on the magnetic strip 1a. The printing head 5 together with the carrier 6, the platen 7 and the printing ribbon mechanism 8 forms a printing portion. The page turning roller 9 is driven by the motor 22. As shown in FIG. 2A, the roller 9 is equipped with relatively flexible rubber members 9a on a sponge. The rubber member 9a has a small change in pressure against deformation. A plurality of suitable rubber members 9a are arranged in the axial direction of the page turning roller 9. Alternatively, the single rubber member 9a may be provided to extend over the entire length of the page turning roller 9. The material of the rubber member must have high frictional resistance and high wear resistance. 5 shows the relationship of the page turning force F to the deformation amount X of the rubber members 9a of the page turning roller 9. As shown in FIG. From Fig. 5, it can be seen that when the amount of deformation X changes between the amounts of deformation a and a 'corresponding to the change range of the bankbook thickness, the page turning force F changes within the normal range between b and b'. 4 shows the relationship of the page turning force F 'to the deformation amount X' of the page turning roller of the conventional apparatus, and when the deformation amount X 'changes between the change amounts c and c' corresponding to the bankbook thickness change range, It can be seen that the force F 'does not change within the normal range between d and d'.

The page turn roller 9 forms an account page turn mechanism with the bank guides 12 and 13, the page turn pad 20, and the page position home position sensor 21. The detector 21 detects that a predetermined number of pages in the account has been turned over and serves to stop the rotation of the motor.

The detector 15 reads the page code (not shown) on the passbook 1 before the printing unit starts printing.

Fig. 6 shows the operation of the hand simulating the operation of the passbook page turning mechanism of the conventional device. When handing over the pages of the bankbook 1 by hand, the center part of the page 1b to be flipped is pressed with the right hand, the page 1b is moved to the right while pushing the page 1b with the left hand, and the page 1b is turned over. In such a case, the left hand that squeezes the page 1b has a large force such that if the right hand and the left hand are not aligned with each other, the bankbook 1 may begin to rotate or the page 1b may not fall smoothly. Crazy

7 shows the operation of the hand, which simulates the operation of the page turning mechanism of the apparatus of the present invention. From the page 1b to be handed over from the bankbook 1 to the bankbook cover c1, the left hand is held between the thumb of the left hand and the other fingers, and the page 1b to be turned over is moved to the right while pushing the page 1b with the left hand thumb. Pass 1b). In such a case, the force for pushing the page 1b to be turned to the right while pushing it with the thumb is greater than the frictional force between the page 1b and the adjacent page of the passbook 1. Further, if the coefficient of friction between the remaining fingers of the left hand and the front cover 1c of the bankbook is greater than the coefficient of friction between the page 1b and the adjacent pages of the bankbook 1, the page turning operation is performed by the bankbook 1's. It can be reliably achieved without causing any movement or rotation.

The device works in the following manner. The bankbook 1 to which data is to be printed is inserted through the inserter 2, and conveyed into the printing apparatus 10 by the plurality of conveying rollers 3a and 3b, on the cover of the bankbook 1. The provided magnetic strip 1a is stopped at a position opposite to the magnetic head 4. While the bankbook 1 is in this position, the reading and writing of the information are carried out. Then, it is conveyed by the bankbook 1 function conveyance rollers 3b to the printing part to which printing is performed. If the printing has to be continued from the first page to the next page, or if a different page has to be printed, the bankbook is returned by the conveying rollers 3c to the bankbook page turning mechanism so that the cover sheet 1c of the bankbook 1 can be printed. ) Comes to rest in the predetermined space shown in FIG. 2A, in contact with the page turning pad 20. When the page turning roller 9 is driven counterclockwise by the motor 22 as shown in FIG. 2A, the rubber members 9a of the page turning roller 9 are placed on the top page (of the bankbook 1). In contact with 1b), the page 1b is rolled up to be positioned on the page turning roller 9. While the rubber members 9a are in contact with the uppermost page 1b of the bankbook 1 during the page turning operation, the bankbook 1 is removed from the stop position by the friction force between the front cover 1c and the page-turning pad 20. It is kept from being displaced. The in-situ detector 21 detects the fact that a predetermined number of pages have been turned over, and thus, when the rotation of the motor 22 is stopped, the conveying rollers 3d are passed through the bankbook 1 as shown in FIG. 2B. ) To end the page turning operation, and then send the passbook 1 to the print section for printing. Before printing starts in the printing section, the detector 15 reads the page code (not shown) of the bankbook 1 to check whether the predetermined number of pages have been handed over without error. When the printing unit has completed printing, the magnetic head 4 updates the information recorded on the magnetic strip 1a on the cover of the bankbook 1, and also conveys rollers 3a, 3b and 3c. Sends bankbook 1 to inserter 2.

3 shows a page turning roller 30 of the passbook printing apparatus according to the second embodiment of the present invention. The apparatus of the second embodiment is distinguished from the first embodiment in that the rubber member 30a mounted on the roller 30 is molded from a material that is hollow and must be relatively flexible but not necessarily sponge-like.

In another embodiment, the page turning pad 20 is pressed against the page turning roller 9 or 30 of the first or second embodiment, so that the force of the rubber member against the amount of deformation of the rubber member of the page turning roller. Compression springs may also be provided to make the relationship of < Desc / Clms Page number 5 > Further, if the spring constant of the compression spring is properly selected, the page turning operation may be achieved by using a normal page turning roller and a compression spring together.

While the present invention has been described with respect to preferred embodiments, the invention is not limited thereto but limited to the scope defined by the appended claims.
