Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet skew correction mechanism in a paper sheet conveying device.

0002

2. Description of the Related Art Conventionally, as shown in FIGS. 7 and 8, a skew correction mechanism for a paper sheet conveying device has been designed to raise and press one end edge of a paper sheet 20, and to an abutment plate 21 that abuts the other end edge on the abutment plate 12;
Some devices are equipped with a link mechanism 22 for standing up. That is, the conventional skew correction mechanism has one abutting mechanism, and corrects skew by abutting only paper sheets of a single width.

0003

[Problems to be Solved by the Invention] However, the skew correction mechanism of this conventional paper sheet conveying device has only one abutting mechanism, so that only sheets of a single width can be placed on the reference side surface. When paper sheets of different widths are conveyed without being able to be pressed, there is a problem in that the skew cannot be corrected.

The present invention has been made in view of the above-mentioned problems, and is a method for correcting the skew of a paper sheet conveying device, which makes it possible to easily correct the skew of paper sheets of different widths. The purpose is to provide a mechanism.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the skew correction mechanism of the paper sheet conveying device of the present invention presses the edge of the paper sheet and abuts it against a reference side surface along the direction of travel. A skew correction mechanism of a paper sheet conveying device that corrects the skew of paper sheets has two abutment mechanisms for abutting paper sheets of two different widths against a reference surface, and either one The structure includes a drive means for selectively operating the abutment mechanism using one drive source.

[0006] Also, a skew correction mechanism for correcting skew of paper sheets of a paper sheet conveying device that conveys two types of paper sheets, narrow paper sheets and wide paper sheets, which have different widths. , a first abutment plate that stands up from a plane position capable of supporting the wide paper sheet to an upright position and abuts the narrow paper sheet against the reference side surface; a second abutting plate that rises from a flat position to an upright position and abuts the wide paper sheet against the reference side surface, and the first abutment plate does not support the wide paper sheet; A spring that can bias the first abutment plate to the upright position, a link mechanism that drives the second abutment plate to two positions, a flat position and an upright position, and a second abutment plate that is interlocked with this link mechanism. The structure includes a stopper that disables the first abutment plate from standing up when the abutment plate is in the flat position and allows the first abutment plate to stand up when the second abutment plate is in the upright position. .

[0007]

[Operation] According to the skew correction mechanism constructed as described above, one of the abutment mechanisms is selectively activated, thereby performing skew correction corresponding to paper sheets of different widths.

[0008]

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 are a top view and a front view showing an embodiment of the present invention, and FIGS. 3 and 4 are a front view and a diagram showing an operating state when a wide paper sheet (passbook A) 13 is used as a medium. 5 and 6 are narrow paper sheets (passbook B) as media.
14 is a front view showing the operating state in the case of No. 14. FIG.

In FIG. 1 and FIG. 2, the embodiment shows a paper sheet conveying device that conveys two types of paper sheets, narrow paper sheets 14 and wide paper sheets 13, which have different widths. A skew correction mechanism for correcting skew feeding of the above-mentioned wide paper sheets 13.
a first abutment plate 10 that stands up from a plane position that can support the above to an upright position and abuts the narrow paper sheet 14 against the reference side surface 12; and a plane position that is located outside the first abutment plate 10. Stand up to the standing position and place the above-mentioned wide paper sheet 13 on the reference side 1.
a second abutting plate 11 that abuts against the second abutting plate 11; and a spring that can bias the first abutting plate 10 to the upright position when the first abutting plate 10 does not support the wide paper sheet 13. 9, a link mechanism L that is provided on the frame 1 and drives the second abutment plate 11 to two positions, a plane position and an upright position; The stopper 8 disables the first abutment plate 10 from standing up when the second abutment plate 11 is in the upright position, and allows the first abutment plate 10 to stand up when the second abutment plate 11 is at the upright position. The link mechanism L is composed of links 2, 3, 4, 5 and levers 6, 7, and is operated by the lever 6 driven by a solenoid (not shown).

Therefore, according to this embodiment, in the normal state, as shown in FIG. stored in position.

As shown in FIGS. 3 and 4, when the wide paper sheet (passbook A) 13 is conveyed, the solenoid moves backward, thereby causing the link 5, lever 6, link 3,
The abutment plate 11 rises via the lever 7 and the link 4. Furthermore, when the second abutment plate 11 rises approximately 50 degrees via the link 5, lever 6, and link 2 (FIG. 3), the stopper 8 is removed. At this time, the first abutting plate 10 is pushed by the wide paper (passbook A) 13 and cannot rise up, and only the second abutting plate 11 stands up.
A wide paper sheet 13 is abutted against the reference side surface 12.

As shown in FIGS. 5 and 6, when a narrow paper sheet (passbook B) 14 is conveyed, the same operation as described above is performed, but at this time, the first abutting plate 10 is pressed against the spring. 9
The edge of the narrow paper sheet (passbook B) 14 is abutted against the reference side surface 12 by the abutting plate 10.

During these operations, the spring 9 has a free length when the second abutment plate 11 is housed, and the first abutment plate 10 is also housed (FIG. 2). Even when the solenoid moves backward and the second abutment plate 11 is raised by about 50 degrees, the force of the spring 9 is still insufficient to push up the passbook. After this, when the second abutting plate 11 is raised and there is no medium on the first abutting plate 10, the second abutting plate 11 is raised by the force of the spring 9. In addition, if there is a medium, the second abutment plate 11 will rise before it rises, causing the medium to sink into the medium.

[0014]

As explained above, according to the skew correction mechanism of the paper sheet conveying device of the present invention, paper sheets of two different widths can be brought into contact with the reference side surface. Moreover, since the two abutting mechanisms can be selectively operated with one actuator, there is an effect that skew correction can be performed extremely efficiently.
