Description

 Media feeder {DEVICE OF SUPPLYING PAPER MEDIUM}

The present invention relates to a media supply apparatus including a pickup discharge portion, and more particularly, to a media supply apparatus having a structure capable of facilitating roller production in an automated teller machine.

Financial automated devices are automated devices that can provide basic financial services, such as deposit or withdrawal, without the need for bank employees, regardless of time and place.

The automated teller machines can be divided into cash dispensers and cash dispensers according to whether or not they are withdrawn. In recent years, the automated teller machines have been used for various purposes such as cash withdrawals, check deposits, bank accounts, and giro payments.

In addition, a paper medium such as cash or check is used for the automated teller machine, and various apparatuses are used to discharge these paper mediums.

In particular, the paper medium can be discharged using a feed roller which is picked up by the roller and feeds the picked up paper medium, and a gate roller for discharging the paper medium one by one.

Among them, the feed roller may provide a rubber roller at a portion in contact with the paper medium. In particular, in order to manufacture the rubber roller, a part of the feed roller must be processed to form a space in which the rubber roller can be combined with the feed roller. By the way, in the case of the body of the feed roller, the cutting process must be accompanied because it uses a metal material such as aluminum, there is a problem that the part price increases due to the cutting process.

The present invention makes it possible to more easily manufacture the device for supplying the paper medium, thereby reducing the time and manpower required to manufacture the device.

The present invention can more easily form a device for supplying a paper medium to reduce the time required to form the device.

According to an embodiment of the present invention for achieving the above objects of the present invention, a media supply device includes a pickup roller for picking up a paper medium; A feed roller provided adjacent to the pickup roller; A gate roller disposed to face the feed roller and passing the paper medium picked up by the pickup roller in a sheet unit; A drive roller coupled to one side of the feed roller; And a pinch roller which keeps meshing with the driving roller and conveys the paper medium passed between the feed roller and the gate roller. Unlike the feed roller, the driving roller may be provided with a lightweight material such as plastic, and may be sufficiently manufactured by an injection process rather than a cutting process.

The driving roller may be provided on one side or both sides of the feed roller, and may be provided spaced apart from the feed roller or in close contact, that is, integrally assembled. In addition, the drive roller may comprise a roller body and an elastic ring, where the outer ring of the roller body may be provided with an elastic ring. The drive roller here can transmit a force for conveying the paper medium while maintaining engagement with the pinch roller. An elastic ring is provided in the form of a strip on the outer surface of the drive roller to improve the frictional force.

Conventionally, the feed roller functions to pass the paper medium one by one with the gate roller, and the pinch roller functions to convey the paper medium. Therefore, a groove or groove for forming a gap with the gate roller may be formed in the conventional feed roller, and a friction surface that rotates together with the pinch roller may be provided at both ends. Therefore, conventional feed rollers must be manufactured through a complicated process, and the design elements to be considered are also various. However, according to an embodiment of the present invention, the feed roller and the driving roller are provided separately but mounted on the same shaft, and can perform a separate function corresponding to the gate roller and the pinch roller, respectively.

According to an embodiment of the present invention, the feed roller and the drive roller to be manufactured separately can be performed more easily than the case of manufacturing a conventional feed roller, the drive roller is to be produced using a plastic injection, etc. This can reduce manufacturing cost and roller weight. In addition, the time and manpower required for the operator to build the device can be saved.
