Description

TECHNICAL FIELD The present invention relates to a so-called passbook printing device for printing on a passbook, a form, etc., and particularly to a passbook printing device suitable for automatic page change of a passbook.

[Prior Art] A conventional device of this type is, for example, Shoukai 55-6617.
There is a turn page mechanism disclosed in Japanese Patent Publication No. 3. This device is designed to obtain the force required for turning pages from the reaction force by the "pushing rod" that presses the passbook against the page-changing rollers and the frictional force between the page-changing rollers and the pages that turn the passbook. Further, the push rod itself is not provided with means for holding a passbook.

[Problems to be solved by the invention]

In the page changing roller used in the above-mentioned conventional technique, the relationship between the deformation amount and the force of the roller is as shown in FIG. 4, and it corresponds to the change in the thickness of the passbook due to the difference in the number of pages. Since it is not possible, the force necessary for turning the page is obtained from the pressing force provided by the pushing rod and the frictional force between the page changing roller and the page turning the passbook. A drive source and the like for driving the motor are required, and the mechanism is complicated and expensive.

Further, in the above-mentioned conventional technology, the fixing of the passbook at the time of page change is entrusted to the conveying roller, and therefore the conveying roller must be fixed so as not to rotate at the time of page change. Also, if the passbook itself has a large force to move in the rotation direction of the page-changing rollers due to the turning force at the time of page change, or if the relationship of the forces is unbalanced, the passbook will move. There was a problem of tilting.

The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the above-mentioned problems in the turn page mechanism of the conventional passbook printing apparatus and to reliably perform page turning by the page changing roller. It is an object of the present invention to provide a passbook printer suitable for automatic page change of a passbook.

[Means for solving problems]

The above-mentioned object of the present invention is, in a passbook type printing apparatus having a printing unit and a passbook page changing mechanism, a page changing roller which constitutes the passbook page changing mechanism has a large friction coefficient and a pressure change with respect to a change in deformation amount. And a passbook printing device characterized by being made of an elastic material having a small friction coefficient, and a passbook holding pad made of a material having a large friction coefficient at a position facing the page changing roller. It is achieved by a passbook printer.

[Action]

In the passbook page changing mechanism in the passbook printing apparatus according to the present invention, the material of the page changing roller is very soft, that is, an elastic body having a small reaction force against deformation is used, and the force required for turning pages is It is obtained from the force generated by the deformation of the page-changing roller made of various materials and the frictional force between the page-changing roller and the turning pages of the passbook.

FIG. 5 is a graph showing the relationship between the deformation amount and the force of the page changing roller used in the page changing mechanism in the passbook printing apparatus according to the present invention. As shown in the figure, in the page changing roller used in the present invention, the change in the force F generated as the reaction force against the change in the deformation amount (change in the thickness of the passbook) is different from that of the conventional one. The force F is within the range necessary for turning the pages of the passbook within the range of change in the thickness of the passbook.

Further, in a passbook page changing mechanism in another passbook printing apparatus according to the present invention, a pad having a very high friction coefficient for holding a passbook is provided directly below the page changing roller.
It is necessary that the coefficient of friction between the pad and the cover of the passbook is higher than the coefficient of friction between the middle sheets of the passbook.

As shown in the reference diagram of FIG. 6, when the conventional turn page mechanism is used to turn the passbook by hand, hold the central part of the page to be turned with the right hand and turn the page to turn with the left hand. In this case, the force to be held by the left hand requires a considerable amount of force, and if the positions of the right and left hands are unbalanced, there was the problem that the passbook would rotate. The passbook page changing mechanism in the passbook printing apparatus of the present invention corresponds to a case where a finger is put under the page to be turned of the passbook and the page is turned only with the left hand, as shown in the reference diagram of FIG. Ensures that the pages are turned, and that the left and right hands are not unbalanced to rotate.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a side sectional view of a passbook printer according to an embodiment of the present invention. In the figure, 1 is a passbook (hereinafter, simply referred to as "passbook"), 2 is an inserter for inserting the passbook 1, 3 is a pair of conveyance rollers, and 4 is recorded on a magnetic stripe 30 provided on the passbook 1. A magnetic head 5 for reading / writing information, a print head 5 for forming a printing portion together with a carrier 6, a platen 7, and a print ribbon mechanism 8, 9 for a passbook guides 12 and 13, a page changing pad 20, a sensor 21, etc., and a passbook page. The page change roller which forms the change mechanism part is shown.

The passbook 1 to be printed inserted from the inserter 2 is sucked into the apparatus by the pair of transport rollers 3. The absorbed passbook 1 is read so as to read the information recorded on the magnetic stripe 30 provided on the cover thereof, so that the magnetic stripe 30 is stopped so as to come to the position of the magnetic head 4.
Here, after reading the information, the passbook 1 is sent to the printing unit to perform necessary printing based on the information.

Here, when the necessary printing is over a plurality of lines and the page is to be printed on the next page beyond the original page, or when it is necessary to print on another page of the passbook 1, the passbook 1 Is sent to the passbook page changing mechanism behind the printing unit. The passbook 1 stopped at a predetermined position is page-changed by the page-change roller 9 driven by a motor 22.

This situation will be described in detail with reference to FIGS. 1 (a) and 1 (b). The page changing roller 9 is a roller covered with a sponge-like relatively soft rubber whose pressure change due to deformation is small. Here, as the material of the rubber itself, it is important that the friction resistance is high and the abrasion resistance is high.

The page change is performed by driving the page change roller 9 by the motor 22 as described above. That is, with respect to the passbook 1 set at the position shown in FIG. 1 (a), the page turning roller 9 is driven counterclockwise by the motor 22 to turn up the uppermost page and turn the page. It is sent out above the roller 9 (the figure shows this state).
At this time, the passbook 1 is page-changed without moving from the stop position due to the frictional force between the cover of the passbook 1 and the page-change pad 20.

The page-changing roller 9 detects that the page-changing home position sensor has changed the page-changing a predetermined number of times and stops the rotation of the motor 22, and thereafter, the passbook 1 in the state shown in FIG. 1 (a). Is moved in the discharging direction (to the left in the drawing) as shown in FIG.

After the page change operation is completed, the passbook 1 is sent back to the printing section, and desired printing is performed on a new page.

At this time, the page code (not shown) printed on the passbook 1 is read by the sensor 15 in advance in order to check whether the page change is performed reliably.

After the printing is completed, the recorded information on the magnetic stripe is updated, if necessary, and is discharged to the inserter 2 and passed to the operator or the like.

According to the above-described embodiment, there is an effect that the structure of the page changing mechanism can be greatly simplified and a highly reliable passbook printing apparatus can be realized.

In the above embodiment, the page-changing roller 9 is a roller covered with sponge-like relatively soft rubber whose pressure change with deformation is small. However, the page-changing roller 9 is not limited to this. As shown in FIG. 3, it is also effective to use a rubber-coated roller having a hollow rubber portion.

It is also effective to urge the page-changing pad 20 toward the page-changing roller 9 with a spring or the like to utilize the pressure of both the page-changing roller 9 and the page-changing pad 20.

[Effects of the Invention] As described above, according to the present invention, in the passbook type printing apparatus having the printing unit and the passbook page changing mechanism, the page changing roller constituting the passbook page changing mechanism has a large friction coefficient and is deformed. Since it is made of an elastic material whose pressure change is small with respect to the change in amount, it is possible to realize a passbook printing device suitable for automatic page change of a passbook, which can surely perform page turning by a page change roller. It is effective.

Further, when a pad made of a material having a large friction coefficient is provided at a position facing the page changing roller, it is possible to completely prevent the passbook from moving during the page changing operation.
The remarkable effect that a passbook printer suitable for automatic page change of a passbook can be realized is achieved.
