Abstract

PURPOSE:To certainly turn over a page by simple constitution and to simplify constitution by mounting a page turning-over part to the rotary shaft of a page turning-over roller through an elastic member. CONSTITUTION:A page turning-over roller 6 is constituted by mounting a page turning-over part 9 to a rotary shaft 7 through a spring 8 being an elastic member. In such a case that the thickness of a passbook 1 is varied by a change of the number of pages when the page of the passbook 1 is turned over by the page turning-over roller 6 of a page turning-over mechanism, the spring 8 is deformed corresponding to the thickness of the passbook 1 by its elastic force and the page turning-over part 9 can follow the turned-over page 1. of the passbook 1 and, therefore, said spring 8 can absorb the thickness variation of the passbook l. Therefore, even when the thickness of the passbook 1 is varied, said variation can be absorbed by the spring 8 and, therefore, the desired page of the passbook 1 can be certainly turned over. Further, since the turning- over of a page can be realized only by the rotation of the page turning-over roller 6, constitution can be simplified as compared with a conventional example using a press pad or a push lever other than the page turning-over roller.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a page changing device suitable for automatically turning over a desired page of a bankbook in a bankbook printing device that prints on bankbooks such as bankbooks and forms. The present invention relates to a mechanism, and particularly to a page changing mechanism in which page turning is performed by a rotating page changing roller.

[Conventional technology]

As a conventional technology of this type of page change mechanism,
There is a technique disclosed in Japanese Patent No. 66173.

In this conventional technology, when it is necessary to turn the pages of a bankbook, a pressing pad located at a position facing the page changing roller and a button lever located at a distance from this move and press the spine of the bankbook, and the spine of the bankbook is pressed. When the inner sheet of the passbook whose pages should be changed is pressed against the page change roller side by the butt and bush lever, the page change roller rotates while making frictional contact with the passbook, so that even if the thickness of the passbook changes, the desired value of the passbook is maintained. The pages are turned over, and if the desired page of the passbook cannot be turned over, the passbook is ejected from the return slot.

[Problem to be solved by the invention]

As mentioned above, in the conventional technology, in order to turn over the desired page of a bankbook, a page changing roller is provided, and a pressing pad is also installed to cope with changes in the thickness of the bankbook due to changes in the number of pages. Since two parts are used, including the bush lever, there are many parts per piece, and a drive means to drive these two parts is also required, which not only complicates the configuration but also requires more than one part. There was an expensive problem.

The object of the present invention is to solve the problems of the prior art described above.

Even if the thickness of passbooks fluctuates due to differences in the number of pages, etc.

To provide a page changing mechanism for a printing device for bankbooks, which can surely turn pages with a simple configuration and can reduce costs by simplifying the configuration.

[Means to solve the problem]

In order to achieve the above object, the present invention is characterized in that a page changing roller that turns over a desired page of a bankbook by rotation has a page turning section attached to a rotating shaft via an elastic member.

[For production]

When the pages of a bankbook are turned by the page changing mechanism, if the thickness of the bankbook changes due to changes in the number of pages, etc., the page changing roller is constructed by attaching the page turning section to the one-rotation shaft via an elastic member as described above. When the page turning section hits the passbook when turning the pages of the passbook by the page changing roller, the elastic member deforms according to the thickness of the passbook due to its elastic force, and the page turning section can follow the turned page of the passbook. Can absorb variations in thickness. Therefore, even if the thickness of the passbook changes, the variation is absorbed by the elastic member, so that the desired page of the passbook can be turned over reliably. Moreover, since page turning can be realized only by rotating the page changing roller, there is no need to use other parts, and the structure can be simplified accordingly, and the cost can be reduced by simplifying the structure.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 4. FIG. 1 is a schematic diagram showing a bankbook printing device to which a first embodiment of the page changing mechanism of the present invention is applied, and FIG. 2 is an enlarged view of the main parts showing the first embodiment of the page changing mechanism of the present invention. It is.

In this passbook printing device, when one #1 is inserted into the inserter 2, that #11 is taken in by a pair of drive rollers 3a, and a pair of drive rollers 3b and 3c are used to position the print head 4 and the platen 5 between the print head 4 and the platen 5. After the predetermined printing is completed, the zero passbook 1 is conveyed to the passbook 1 and printed by the print head 4, and is ejected to the inserter 2 by rotating the drive rollers 3c, 3b, and 3a in the reverse direction.

On the other hand, when the print head 4 is printing, when it is necessary to print from the current print page to the next page, the passbook 1 is moved to a predetermined position of the page change mechanism located behind the print position by a pair of drive rollers 3c and 3d. After the passbook 1 is transported and the next page of the passbook 1 is turned over by the page changing mechanism at that position, the passbook 1 is sent to the printing position again, where printing is performed, and the passbook 1 is ejected to the inserter 2.

The page changing mechanism includes a page changing roller 6. As shown in FIG. 2, the page changing roller 6 has a page turning section 9 attached to a rotating shaft 7 via a spring 8 as an elastic member.

The rotating shaft 7 is connected to the motor 10 shown in FIG. 1, and when the page 1111 that needs to be turned is conveyed to a predetermined position of the page turning mechanism, the rotating shaft 7 is connected to the motor 10 shown in FIG.
is detected by the motor 10. The page turning unit 9 directly turns over a desired page of the bankbook 1 by rotating when it comes into contact with the bankbook 1, and has a spring 8 whose end is attached to the rotating shaft 7.
It is attached to the other end and is made of rubber or the like with a high coefficient of friction so that the page can be turned reliably when it comes into contact with the passbook 1, for example. The spring 8 is made of a plate, and when the thickness of the passbook 1 changes due to a change in the number of pages, etc., the spring 8 is deformed by its own elastic force to absorb the change in thickness.

In addition, when the thickness of the passbook changes due to the difference in the number of pages opened on both sides of the passbook 1, the page turning unit 9 always applies approximately -like pressure to the turned page 1' of the passbook 1, regardless of the thickness.
Its outer circumferential surface is placed at an eccentric position with respect to the rotating shaft 7 so that it can act on the surface. Therefore, the outer peripheral surface of the page turning section 9 is selected at an appropriate position so that even if the thickness of the bankbook 1 changes, a uniform pressure can be applied to the turning page 1' of the bankbook 1.

Since the page change mechanism of the embodiment has the above-mentioned configuration, 1
Next, its operation will be described.

If it is necessary to change the page to the bank@1 when printing the bankbook 1, when the bankbook 1 is conveyed to a predetermined position of the page changing mechanism, the sensor 11 detects the bankbook 1 and the motor 10 is driven. As a result, the page changing roller 6 rotates, and the page turning section 9 of the page changing roller 6 rotates in frictional contact with the turning page 1' of the bankbook 1, thereby turning the bankbook 1 as shown in FIG. When the page 1' is bent and the turned page 1' passes over the page changing roller 6 as shown by the broken line in the figure, the pair of drive rollers 3d transports the passbook 1 to the printing position side, and the turned page 1 is ′ is turned over and conveyed to the printing position.

When the page changing roller 6 of the page changing mechanism turns the pages of the bankbook 1, if the thickness of the bankbook 1 changes due to changes in the number of pages, etc., the page changing roller 6 rotates through the rotation shaft 7 via the spring 8 as described above. Since the turning section 9 is attached, the spring 8 deforms according to the thickness of the bankbook 1 due to its elastic force, and the page turning section 9 can follow the turning page 1' of the bankbook 1, so that the thickness of the bankbook 1 can be changed. Can absorb fluctuations. Therefore, even if the thickness of the passbook 111 changes, the variation is absorbed by the spring 8, so that the desired page of the passbook 1 can be turned over reliably. Moreover, since page turning can be realized only by rotating the page changing roller 6, the configuration can be simplified compared to the conventional example in which a suppressing pad or a bushing lever is used in addition to the page changing roller.

Further, even if the outer circumferential surface of the page turning section 9 is arranged at an eccentric position with respect to the rotating shaft 7 and the thickness of one bankbook 1 changes.

The spring 8 is designed so that approximately -like pressure can always be applied to the turning page 1' of the passbook 1 regardless of its thickness.
Even if the elastic force of the passbook 1 is weak, it can sufficiently cope with variations in the thickness of the passbook 1.

FIG. 3 shows a second embodiment of the page change mechanism according to the present invention.

This embodiment differs from the first embodiment in that the page change roller 6 includes a correction member 12 capable of correcting abnormal deformation of the spring 8.

That is, the correction member 12 has a cylindrical shape except for the mounting portion 12a, which is a part of the outer periphery, and is fixed in a concentric position with respect to the rotating shaft 7.
The spring 8 is supported by overlapping both ends of the passbook 1, and when the spring 8 hits the surface of the page 1' of the passbook 1 when the pages are turned, the spring 8 tends to deform abnormally due to aging etc. is suppressed to correct abnormal deformation of the spring 8.

The spring 8 has a U-shaped plate body, and both ends of the spring 8 are supported by the spring guide 12, and the middle part side to which the page turning section 9 is attached is used for the purpose when the page turning section 9 turns the pages. The spring guide 12 and the space 13 are separated from each other so that an elastically deformed state can be formed.

In this embodiment, when the page turning part 9 of the bankbook 1 hits the turning page 1' of the bankbook 1 when the page of the bankbook 1 is turned by the page changing roller 6, if the spring 8 has deteriorated over time, the spring 8 becomes abnormal. This may result in severe deformation and may not be able to accommodate variations in the thickness of one bankbook 1. However, as described above, the correction member 12 fixed to the one-rotation shaft 7 can suppress abnormal deformation of the spring 9 and correct the abnormal deformation of the spring 8. It becomes possible to turn pages normally for a long period of time, and the function of the spring 8 can be maintained for a long period of time.

FIG. 4 shows another embodiment of the page change mechanism according to the present invention.

In this case, the spring 8 is formed as a spiral plate. The correction member 14 holds the spring 8 in the form of a spiral plate, and its inner end is fixed to a spring support 15 attached to the rotating shaft 7 together with the spring 8. A page turning section 9 is attached to its outer end. In this embodiment, even if the spring 8 has deteriorated over time when the pages of the passbook 1 are turned by the page changer, the correcting member 14 corrects the abnormal deformation of the spring 8, so that the spring 8 functions properly. is maintained for a long period of time. Therefore, even if the correcting part 14 has a shape that is parallel to the spring 8, the function of the spring 8 is not impaired. Therefore, according to this embodiment, the same as that of the second embodiment is achieved. It can be effective.

〔Effect of the invention〕

As described above, according to claim 1 of the present invention.

When the page turning part of the first page changing roller hits the bankbook when turning the pages of the bankbook with the page changing roller, the elastic member deforms according to the thickness of the bankbook due to its elastic force, so as to absorb the variation in the thickness. This makes it possible to reliably turn the desired page of a bankbook even if the thickness of the bankbook changes.Furthermore, page turning can be achieved by only rotating the single page changing roller, so other parts can be used. This becomes unnecessary and the configuration can be simplified accordingly, which has the effect of reducing costs.

Further, according to claim 2 of the present invention, the outer circumferential surface of the page turning section is arranged at an eccentric position with respect to the rotation axis, so that even if the thickness of the passbook changes, the approximately -like pressure is always maintained regardless of the thickness. Since it is designed to be able to act on the turning pages of the passbook, variations in the thickness of the passbook can be adequately coped with.

Furthermore, according to claim 3 of the present invention, since the elastic member has a correction member capable of correcting abnormal deformation due to aging, the function of the spring can be maintained for a long period of time by the correction member. It has the effect of
