Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] A touch lever is pivotally supported on the shaft of a page-turning roller that abuts against a passbook and rotates, and the lever is projected from the side surface of the page-turning roller to the outer peripheral side of the roller, and the Even if the space is tight, you can check the page turn by making sure that the tip of the flipped page hits against it, and by installing a sensor detection part in the part that extends from the lever to the outside of the passbook passage, you can check the page turn. Let the page turn over until it is finished.

[Industrial application field]

In financial institutions and the like, the contents of past transactions are automatically recorded in a bankbook or the contents are automatically recorded when a transaction of cash is made by a bookkeeping machine. In such a device that handles a passbook, when turning a page and recording on the next page, a device that once ejects the passbook and the customer turns the page and then inserts it again into the device and restarts recording, There is a device that automatically turns pages. The present invention relates to a mechanism for ensuring that page turning is always performed in an automatic page turning apparatus in the latter device.

[Conventional technology]

FIG. 4 is a conventional page turning mechanism, (a) is a plan view,
(B) is a right side view. A head carrier 3 having a print head 2 mounted thereon is supported on a guide shaft 1 shown in FIG.
The passbook is printed between the platen 5 and the platen 5. A gap between the upper plate 6 and the lower plate 7 is a passbook passage 8. A pinch roller 9 and a turning roller 10 are arranged to face each other so as to sandwich the passbook passage 8 and are supported by roller bearings 11, respectively. The turning roller 10 includes a roller bearing 11 via a drive shaft 10a.
Supported by.

Now, when the customer inserts the passbook from the passage insertion port 12 with the page to be recorded opened, the sensor (not shown) detects the print line and the line to be printed is positioned on the platen 5 so as to be illustrated. Not positioned by the roller. Then, when the predetermined information is printed and the print lines are insufficient, the next page is turned by the page turning mechanism.

FIG. 5 is a side view showing the page turning operation. When there are not enough print lines, the passbook N passes over the platen 5 as shown in FIG.
However, it is sandwiched between the pinch roller 9 and the turning roller 10. Then, by rotating the turning roller 10, the medium 15 of the top page is turned as shown in FIG. That is, in the fixed passbook N, the medium of the top page
Only 15 starts to bend due to the counterclockwise rotating force of the turning roller 10. Then, as shown in (c), with the tip of the medium 15 abutting the outer periphery of the turning roller 10,
Then, as shown in (d), the elastic force (stretching force) of the medium 15 causes the medium 15 to bounce up from the turning roller 10 to cover the turning roller 10.

Next, as shown in (e), with the pinch roller 9 retracted to the lower side, the turning roller 10 is reversed to return only the medium 16 being double-turned to its original state. Then (f)
As described above, the turning roller 10 is rotated in the clockwise direction and the pinch roller 9 is rotated in the counterclockwise direction. When the passbook N is transferred to the left side, the medium 15 is reversed to the right side by the turning roller 10 and the passbook N is It is transferred onto the platen 5 and printed by the print head. When printing is completed, the paper is ejected to the passbook insertion slot.

[Problems to be solved by the invention]

In this way, in the mechanism for turning the page of the passbook with the roller, the environmental condition is satisfied and the turning operation is performed once.
It suffices if the page turning is performed completely, but if the medium 15 of the passbook N is dusty and slippery, the page turning may fail.

If the page cannot be turned in this way, the printing line cannot be detected when printing is performed on the platen 5. Therefore, conventionally, the passbook N is once discharged to the passbook insertion slot 12 and the customer is requested to turn the page. Then, after turning the page, it was solved by inserting it again into the device.

However, even if the page turning is incomplete in the first operation, it is often possible to surely turn the page by performing the page turning operation again. Alternatively,
In some cases, the medium 15 has moved to the middle of the turning operation, and if the turning roller 10 is further rotated, the turning can be surely performed. Furthermore, due to slippage between the roller and the page, although the page could not be completely turned by one turning operation, the page turned halfway as if the page turning was completed. If the passbook is conveyed as it is for the purpose of printing or detecting the page mark, the bent page may be pinched by the rollers and the page may be broken.

Therefore, the present invention immediately detects whether or not the page turning has been performed reliably, and when the page turning is not completed or in the middle of the turning operation, the turning roller 10 is further operated to always turn the page turning surely. By being performed, it is to realize the full automation of the page turning operation.

[Means for solving problems]

1A and 1B are views for explaining the basic principle of a page turning mechanism according to the present invention. FIG. 1A is a plan view and FIG. 1B is a side view.
The present invention inserts a passbook between a pair of rollers to form a medium (15).
In a page-turning mechanism for turning the page by pressing the turning roller (10) and rotating it in the turning direction, the tip of the medium (15) rotatably supported and turning the page (10). ), The touch lever (20) is provided at the position where the touch lever (20) is struck just before it jumps up, and the medium (15) is struck.
0) has a detecting means (21, 22) for detecting that it has rotated.

[Action]

The tip of the medium 15 that is turned by the rotation of the turning roller 10 is guided to the upper side of the turning roller 10 while hitting the outer periphery of the turning roller 10 and jumps up from the turning roller 10 by the elasticity of the medium 15, but the tip of the medium 15 The turning roller
Before it is separated from 10, it hits against the tip of the touch lever 20 and presses the touch lever 20 to rotate it in the direction of arrow a2. Then, with the tip of the touch lever 20 retracted and retracted from the outer periphery of the turning roller 10,
Jumps up and covers the turning roller 10. When the touch lever 20 is rotated by the medium 15, the touch lever 20 is rotated by the medium 15.
The detection lever 22 integrated with 20 rotates, and it is detected by the sensor 21 that the medium 15 is surely turned over.

However, even if the turning roller 10 rotates by a predetermined angle, the medium
If the tip of 15 does not move above the turning roller 10,
Since the medium 15 does not reach the touch lever 20, the detection lever
22 does not rotate and end of page is not detected.

Therefore, the turning roller 10 further rotates. That is, the turning roller 10 rotates until the medium 15 reaches the touch lever 20 and rotates the touch lever 20 and the detection lever 22 and the sensor 21 detects it.

〔Example〕

Next, practical examples of how the page turning mechanism according to the present invention is embodied will be described. FIG. 2 is a view showing an embodiment of a page turning mechanism according to the present invention, (a) is a plan view and (b) is a right side view. The turning mechanism of the passbook N is the same as that of the conventional device shown in FIG. In this example,
The structure is such that the torsion coil spring 23 is wound around the shaft 10a of the turning roller 10. The straight portion 20 at one end serves as a touch lever, which projects from the side surface of the turning roller 10 to the outer circumference of the turning roller 10 so that the medium 15 of the passbook N abuts against it. The straight portion 24 at the other end is bent like a crank, and a weight 25 is attached to the middle portion. The tip is the detection lever 22. The detection lever 22 is provided with a shield plate 26, and whether the shield plate 26 is located at a position facing the sensor 21 or not is used to detect whether page turning has been performed.

FIG. 3 is a diagram showing the operation of the apparatus of this embodiment. When the tip of the medium 15 moves to the upper side of the turning roller 10 as shown in FIG. 3 (a) by the operation of (a) to (c) of FIG. 5, the tip of the medium 15 hits the touch lever 20. .
When the turning roller 10 further rotates in the counterclockwise direction, the extension force of the medium 15 causes the touch lever 20 to rotate in the direction of arrow a2, resulting in the state of (b). Touch lever like this
When 20 is rotated and the tip of the medium 15 is released from the touch lever 20, the medium 15 jumps up and extends as shown in (c), and the touch lever 20 is released from the medium 15, so that the medium of (a) is again released. It returns to the original state and prepares for the next detection.

When the touch lever 20 is rotated by the medium 15 in this way, the detection lever 22 at the other end also rotates together, and the shielding plate 26 separates from the sensor 21 as shown in (b) and is detected by the sensor 21. As a result, the turning roller 10 rotates clockwise and the pinch roller 9 rotates counterclockwise to transfer the passbook N to the left side, position it on the platen 5, and perform printing on a predetermined line. When the passbook N is transferred onto the platen 5 in this manner, the medium 15 is reversed by the turning roller 10 in the arrow a1 direction.

A weight 25 is provided on the detection lever 22 side, and the touch lever 20 released from the medium 15 is configured to return to the original state due to the weight of the weight 25, but a return spring is provided to return by the spring force. You may let me.

Further, in the embodiment of FIG. 2, the drive shaft 10a of the turning roller 10 is inserted into the torsion coil spring 23, and the torsion coil spring 23
The straight portions formed in advance on both ends of are used for the touch lever 20 and the detection lever 22. In contrast,
It is also possible to form the touch lever 20 and the detection lever 22 by forming the strip plate material into a U shape as shown in FIG. 1 (a), for example, so that both levers 20 and 22 can rotate integrally. it can.
In addition, the touch lever 20 may be provided at one end of the tubular body and the detection lever 22 may be provided at the other end of the tubular body to integrate them.

〔The invention's effect〕

As described above, according to the present invention, the touch lever 20 is projected from the side surface of the page turning roller 10, and the touch lever 20 is rotated by hitting the touch lever 20 immediately before the medium 15 jumps up from the turning roller 10. ing. When the medium 15 hits the touch lever 20 and the touch lever 20
After that, the page turning is completed by the rotation of the page turning roller 10 and the pinch roller 9 thereafter. Therefore, the page turning is surely detected by the touch lever 20, and when the touch lever 20 is not rotationally driven, the turning roller 10 is further rotated, so that the page turning can be always performed reliably. In addition, the sensor for detection 21
Since the detection lever 22 and the detection lever 22 are arranged outside the passage of the passbook N and the detection lever 22 and the touch lever 20 are integrally connected, the detection means is provided at a position avoiding a narrow passbook passage. It can be installed and does not hinder the miniaturization of the device.
