DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bill discriminating apparatus and a bill discriminating apparatus mounted on a bill processing unit and discriminating bills.

[0002]

2. Description of the Related Art A bill discriminating apparatus has a transport path horizontally in a main body of the apparatus, transports bills along the transport path, detects information on the transported bills by an optical sensor, and determines whether the bill is correct or not. It is designed to discriminate. A transport roller and a roller base are provided in the transport path, and the banknote is transported by rotation of the transport roller.

When paper money is transported, paper dust and the like adhere to the transport roller. As a countermeasure, a paper scraper (scraping claw) or a sponge material is pressed against the transport roller to scrape the paper dust. The scraped-off paper dust falls due to gravity and is stored in a paper dust storage unit provided outside the apparatus main body.

In recent years, a bill processing unit on which a bill validator is mounted has been remarkably reduced in size in recent years, and the degree of freedom in mounting an internal device has been reduced. For this reason, the bill discriminating apparatus is often arranged vertically so that the transport path is vertical. When the bill validator is arranged in this manner, the paper dust scraped off by the scraper stays below the transport roller.

[0005]

However, in the prior art, since the paper powder staying below the transport roller is left as it is, the paper powder flows backward from the gap between the transport roller and the roller base to the transport path, and the optical path of the optical sensor. There is a problem in that the gap between the transport roller and the roller base is clogged with paper dust, which causes a rotational load on the transport roller.

Accordingly, the present invention prevents paper dust removed from the transport roller from staying below the transport roller, thereby preventing backflow into the transport path and preventing clogging between the transport roller and the roller base. It is an object to provide a leaf discriminating device and a bill discriminating device.

Exhausted from 6.

In the meantime, a scraper 31 as a removing means is provided in the vicinity of the driving roller 22a of the conveying roller pair 22. The scraper 31 is composed of a leaf spring 32 as an elastic member, and a resin part 33 as a contact part having a heat resistance and an abrasion resistance which is integrally formed at the tip thereof and is divided into a plurality of parts in the width direction. 33 so that the roller base 33 elastically contacts the drive roller 22a.
Attached to. A paper dust storing section 36 for storing the paper dust 35 is provided below a portion where the resin portion 33 of the scraper 31 contacts the transport roller 22a.

As shown in FIG. 3, the paper dust storing section 23 is slidable so that it can be easily attached to and detached from the banknote discriminating apparatus 1, so that not only the maintenance personnel of the apparatus but also the operator of the banknote processing apparatus can use it. The paper dust that has accumulated can be easily cleaned.

In the ATM 2, one of the two device surfaces in the upright direction is defined as a maintenance surface due to the location of the installation location or restrictions on the device design. Needless to say, the paper dust storing section 36 can be detached from the maintenance side of the bill validating apparatus 1 without removing the paper dust storing section 36 from the maintenance section.

FIG. 4 shows a driving roller 22 of the conveying roller pair 22.

FIG. 6 shows a second embodiment of the present invention. A banknote handling device used in a bank or the like in which the banknote discriminating device 1 is mounted has two main applications. One is a cash processor which is directly operated by an operator, and the other is an opportunity for an operator to directly operate. There are applications such as automatic machines such as ATM / CD which are installed in automation corners where there is little.

In the former case, since the number of processed banknotes is large and the operator operates directly, the operator can discard the paper dust stored in the paper dust storage unit 36 as described above.
In the latter case, although the number of sheets to be processed is relatively small as compared with the cash processing machine, the operator does not access the bill processing apparatus unless the automatic machine or the like is stopped due to an obstacle or medium replenishment.

Therefore, it is necessary to make the paper dust storage section 36 large enough not to overflow at least until the maintenance personnel discards the paper dust at the time of periodic inspection. However, in the case where the size of the paper dust storage unit 36 cannot be sufficiently obtained as described above, FIG.
As shown in the figure, the paper dust storage unit 3
Instead of 6, a skewed chute 37 can be provided to discharge the falling paper dust 35 to the outside of the apparatus main body 14.

In this case, when the paper dust 35 discharged outside the bill validator 1, that is, into the bill processing unit 6 has a bad influence on the bill processing unit 6, a paper dust storage unit as shown in FIG. 38 may be provided.

FIGS. 7 and 8 show a third embodiment of the present invention. Drive roller 2 of transport roller pair 22
2a is supported at both ends by bearings, which are supported by a roller base 42. An opening 43 is provided on the side of the roller base 42 where the scraper 31 comes into contact with the transport roller 22a, and through which the paper dust 35 removed from the drive roller 22a is discharged to the outside of the apparatus main body 14.

The opening 43 has a rib 4 as a projection.
4, 44 are protruded. The ribs 44, 44 are interposed in the grooves 22b, 22b of the drive roller 22a so as to enter inside the outer peripheral surface of the conveyance. These ribs 44, 44
With this intervention, the paper dust 35 scraped off from the outer peripheral surface of the transport of the drive roller 22a is regulated so as not to fall into the grooves 22b.

Since the outer peripheral surfaces of the roller base 42 and the driving roller 22a are arranged with a minimum clearance, the paper dust 35 scraped off by the scraper 31 is removed when the ribs 44 are not interposed. The light enters the grooves 22b, 22b of the nozzle 22a and flows backward to the conveying surface due to the rotation of the drive roller 22a, thereby blocking the optical path of the optical sensor 28 and causing erroneous detection.

[0036]

As described above, according to the present invention, the paper dust adhered to the conveying means (conveying roller) is removed by the removing means, and the removed paper powder is stored in the storing section provided in the apparatus main body. Paper dust flows back from the gap between the transport roller and the roller base to the transport path, blocking the optical path of the optical sensor and causing erroneous detection. The function and performance of the apparatus can be maintained favorably without any rotation load.

Further, since the storage section is provided detachably, the storage section is periodically taken out to collect paper dust,
It is also possible to prevent paper dust from overflowing from the storage section. Further, since the guide means for guiding the paper dust removed by the removing means to the outside of the apparatus main body is provided, the paper dust can be removed to the outside of the apparatus main body without manual removal operation.

Further, a plurality of grooves along the circumferential direction are formed in the outer peripheral surface of the transport roller in the axial direction, and the transport guide has an opening for exposing a part of the transport roller and opposite side edges of the opening. Since the bridge piece is interposed and interposed in the groove of the transport roller in a nested manner, paper sheets (banknotes) transported along the transport guide are guided along the bridge piece at the opening, There is no danger that the leading end of the opening comes into contact with the inner edge of the opening and becomes jammed.

Further, since the roller base is provided with a projection which is nested in the groove of the transport roller, the removed paper dust can be prevented from flowing back to the transport path via the groove of the transport roller. .

Further, the paper dust removing means has a structure in which the paper dust is elastically brought into contact with and pressed against the transport roller, so that the gap adjustment becomes unnecessary and the paper dust can be reliably removed. Further, since the paper dust removing member is divided in the axial direction of the transport roller, it can be easily and surely brought into contact with the transport roller.
