Abstract

PROBLEM TO BE SOLVED: To provide a paper sheet guide device capable of reducing a carrying load in the confluent part of a paper sheet carrying path, and being installed in a limited space. SOLUTION: This paper sheet guide device is provided in the confluent part between first and second paper sheet carrying paths 70 and 72 for demarcating a curved paper sheet carrying path in the confluent part, and is equipped with a guiding member turnably fitted to a device frame, a torsion spring 66 fitted to the turning shaft of the guiding member to turn the guiding member in a direction for narrowing the curved paper sheet carrying path, and a stopper for ensuring the curved paper sheet carrying path having a given width against the urging force of the spring 66 by being fixed to the guiding member and abutting on the device frame. The spring 66 is constituted so as to have a sufficiently weak spring constant so that the collision of the pater sheet, carried on the curved paper sheet carrying path, with the guiding member can turn the guiding member against the energizing force of the spring 66, to expand the width of the downstream side of the curved paper sheet carrying path.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper guide device provided at a junction of a paper transport path for transporting paper such as bills.

2. Description of the Related Art Banknote automatic teller machines (ATMs) have been remarkably popularized, and have recently been installed not only in financial institutions such as banks but also in stores such as supermarkets and convenience stores.

[0003] The internal mechanism of the ATM is composed of components mounted at a high density, and it is difficult to secure a transport path for transporting bills smoothly at the confluence of the transport paths. is there.

[0004]

2. Description of the Related Art FIG. 1 is a view showing an example of a conventional paper guide device provided at a confluence of a banknote transport path in an ATM. A guide block (guide member) 6 is fixed between the flat guide plate 2 and the curved guide plate 4.

The guide block 6 has a curved surface 6a and a flat surface 6b having a radius of curvature substantially the same as the radius of curvature of the curved guide plate 4, and the first conveyance is performed by the curved guide plate 4 and the curved surface 6a of the guide block 6. The path 8 is defined, and the second conveyance path 10 is defined by the flat guide plate 2 and the flat surface 6b of the guide block 6.

[0006] The bill 12 conveyed through the first conveying path 8
The transport direction is gradually bent by the front end colliding with the curved surface 6a of the guide block 6, and the
Conveyed toward.

As described above, conventionally, a guide block having a curved surface is provided at the confluence of the banknote transport path, and the bending of the transport path is made as small as possible to reduce the banknote transport load. (Clogging of banknotes).

[0008]

In the above-described structure at the confluence of the banknote transport path as described above, the degree of bending when the banknote is transported is uniquely determined by the radius of curvature of the curved surface of the guide block. There is a problem in that the load on the bill increases at a location where the bend is strong, and the jam of the bill occurs at the junction of the transport path.

If the radius of curvature of the curved surface of the guide block is increased, the occurrence of jamming can be reduced, but such a design is almost impossible because components are mounted at high density.

SUMMARY OF THE INVENTION The present invention has been made in view of the foregoing, and it is an object of the present invention to smoothly carry a sheet without causing paper jam at a junction of a sheet carrying path. The purpose of the present invention is to provide a paper guide device capable of performing the following.

[0011]

According to the present invention, there is provided a sheet guide device provided at the junction of a first sheet conveyance path and a second sheet conveyance path defining a curved sheet conveyance path at a junction. A guide member rotatably attached to the apparatus frame, a torsion spring attached to a rotation shaft of the guide member, and rotating the guide member in a direction to narrow the curved paper conveyance path; A stopper fixed to the guide member and securing the curved paper conveyance path having a predetermined width against the urging force of the torsion spring by abutting on the apparatus frame, wherein the torsion spring has the curved shape. When the sheet conveyed along the sheet conveying path collides with the guide member, the guide member rotates against the urging force of the torsion spring, and rotates along the curved sheet conveying path. To enlarge the width of the flow side, the sheet guide device is provided which is characterized in that it has a sufficiently low spring constant.

When the paper conveyed along the curved paper transport path collides with the guide member, the guide member rotates against the urging force of the torsion spring, and the downstream width of the curved paper transport path is increased. You. Therefore, the load on the paper transport is reduced, and the occurrence of jam at the junction of the transport path can be reduced.
