Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] A mechanism for page turning of a medium in a bookkeeping machine, wherein the direction of rotation of the feed roller is changed between when the medium is being conveyed and when the page is being turned, so that the feed roller is turned over. It can be used for both transportation and page turning.

[Industrial application field]

The present invention relates to a page-turning mechanism that also serves to convey a medium, and more specifically, by switching the rotation direction of the feed roller without providing a unit dedicated to page-turning between the pitches of the feed rollers provided at a predetermined pitch. ,
The present invention relates to a page-turning mechanism that can only carry a medium and can turn a page while carrying a medium.

In the printing section of the recording machine, print on a medium such as a passbook.
When performing on a page different from the state in which the medium is inserted, or when printing over two or more pages, a page turning mechanism is provided in the bookkeeping machine in order to automatically change pages by turning over the cover or inside paper. It is provided.

Since the page-turning mechanism is provided in the medium-conveying path from the medium-inserting port of the bookkeeping machine to the printing section, the page-turning mechanism saves space in order to reduce the space around the conveying path, and reduces the cost. It is desired to reduce the processing time.

[Conventional technology]

In order to perform page turning in the conveying path connecting the medium insertion port of the bookkeeping machine and the printing section, conventionally, as shown in FIGS. 7 and 8, for example, a unit dedicated to page turning is provided.

In FIGS. 7 and 8, the feed rollers 2 are arranged at a predetermined pitch along the conveying path 1. Reference numeral 3 denotes a driving roller of the feed rollers 2, which is connected to a pulse motor 4 as a driving source. A turn page mechanism unit 5 is provided at an intermediate position of the installation pitch of the feed roller 2. In the turn page mechanism section 5, 6 is a turning roller, 7 is a pulse motor as a driving source of the turning roller 6,
Reference numeral 8 is a pressure part that can take a position in contact with the transport path 1 shown in FIG. 7 and a position retracted from the transport path 1 shown in FIG.

In such a conventional structure, in order to convey the medium 9,
After the pressure part 8 is moved to the retracted position as shown in FIG. 8, the drive roller 3 is rotated as shown by the arrow in FIG. 8, and the medium 9 is conveyed and inserted from the printing section as shown in FIG. It is transported in the direction toward the mouth. When the drive roller 3 is rotated in the reverse direction, the medium 9 is conveyed in the direction from the medium insertion port toward the printing section.

In order to perform page turning with this conventional structure, the medium 9 is moved to a position straddling the feed roller 2 and the turn page mechanism unit 5, and the rotation of the drive roller 3 is stopped. When the turning roller 6 is rotated counterclockwise as shown in FIG. 7 by moving it to a position in contact with the conveying path 1 as shown, the page in contact with the turning roller 6 is lifted while the entire position of the medium 9 is stopped. . After that, the rotation of the turning roller 6 is stopped and the pressure part 8 is retracted, and then the medium 9 is fed to the left in FIG. 7, the page is turned.

[Problems to be solved by the invention]

In this conventional method, since the turn page mechanism section 5 dedicated to page turning is provided, a large space is required and the cost is increased. In particular, since the installation pitch of the feed rollers 2 is determined depending on the minimum length of the medium 9 to be processed, it is not possible to provide such a turnpage mechanism unit 5 in a limited space between such feed rollers. However, the structure was also complicated.

Further, it is necessary to stop the medium 9 once at the position shown in FIG. 7, and after the turning roller 6 is actuated, the medium 9 is moved to the left again to complete the page turning. The drawback was that it took a long time.

The present invention was created in view of such a point, and a part of the feed roller also serves as a page-turning roller with a simple structure, so that the dedicated turn page mechanism section is eliminated and the sheet is conveyed. It is an object of the present invention to provide a page turning mechanism capable of reducing the space around the road, reducing the cost, and shortening the processing time of the page turning.

[Means for solving problems]

The above-mentioned purpose is, as shown in FIG. 1, in the medium transport path 1 for transporting the medium 9 inserted from the medium insertion port of the bookkeeping machine with the binding margin side at the head to the processing section side for processing the medium 9. Feed rollers 11 and 12 provided on both sides of the transport path 1 for sandwiching and transporting a medium 9, and a drive source 1 for rotationally driving the feed rollers 11 and 12.
3 and one of the feed rollers 11 are rotationally driven in the conveyance direction of the medium 9, and the inside paper 1 on the side in contact with the other feed roller 12
7 or the transmission means 14 for transmitting the driving force of the drive source 13 so as to rotationally drive the other feed roller 12 in the direction of turning the cover, and the rotation direction of the other feed roller 12 in the middle paper 1 of the medium 9.
7 or a switching means 15 for switching from the flipping direction of the cover, and while feeding the medium 9 from the processing section side to the medium insertion port side, the feed rollers 11 and 12 are rotationally driven in the same direction to perform page turning. This is achieved by providing a page turning mechanism that conveys to the processing unit side.

[Action]

In the transport path of the bookkeeping machine to which the page-turning mechanism of the present invention is applied, the medium 9 is bound on the binding margin side so that the sheets at the free end do not come apart and are not inadvertently flipped when being inserted into the medium insertion port. Is inserted from the medium insertion opening with the head at the top. Medium 9
In order to convey the sheet, the drive source 4 rotationally drives the drive roller 3 counterclockwise, and the drive source 13 rotationally drives one feed roller 11 counterclockwise via the transmission means 14. When the other feed roller 12 is released from the rotational drive in the same direction as the one feed roller 11 by operating the switching means 15, the medium 9 is conveyed leftward in FIG. 1, that is, in the direction from the printing portion toward the medium insertion port. To be done. If the drive roller 3 and one of the feed rollers 11 are reversed,
The medium 9 is conveyed in the direction from the medium insertion port toward the printing unit. In this way, when the medium is fed, the page turning mechanism of the present invention operates the medium feeding together with the other medium feeding mechanism 16.

Next, in the conveying path of the bookkeeping machine to which the page turning mechanism of the present invention is applied, in order to turn the page, the driving roller 3 is used.
Is rotated counterclockwise as shown in FIG. 1 to move the medium 9 leftward in FIG. 1, that is, from the printing section to the page turning mechanism 10.
Transport it to. The feed rollers 11 and 12 are both rotationally driven in the counterclockwise direction by the drive source 13 via the transmission means 14 (page turning operation). Therefore, the medium 9 approaching the page turning mechanism 10 is one of the feed rollers. While being continuously conveyed to the left by 11, the inside paper 17 or cover of the medium 9 which is in contact with the feeding roller 12 is turned by the other feeding roller 12. After the medium 9 once passes through the page-turning mechanism 10, the switching means 15 is operated and one of the feed roller 11 and the driving roller 3 is rotationally driven in the clockwise direction to convey the medium 9 to the printing section ( It is possible to perform printing on the page after the page is turned over in the medium conveying operation).

In this way, by providing the page turning mechanism that also serves as the feeding of the medium according to the present invention, it is not necessary to provide a dedicated turn page mechanism section and the like, which contributes to space saving and cost reduction. Moreover, according to the mechanism of the present invention, page turning can be performed while the medium is being conveyed in one direction, so that the processing time can be shortened.
