Benefits of technology

"The invention provides an improved stacker wheel that solves problems of existing stacker wheels. The curved tines on the wheel are flexible and have a larger opening between them, making it easier to insert media between them. The tines also allow for flattening of the media and hold them gently with minimal deformation. The stacker wheel is lightweight and can be easily manufactured. It can be connected together with other similar stacker wheels. The invention also provides a media dispenser and an automated teller machine including the stacker wheel. The technical effects of the invention include improved performance and reliability of the stacker wheel and its assembly."

Problems solved by technology

Although currency notes are quite easily deformed, if thicker and / or stiffer media such as train tickets are to be dispensed, large stresses are exerted on the media which may result in damage to the media (e.g. scoring, creasing etc).

Embodiment Construction

[0044]FIGS. 3A-3D are detailed diagrams of an example of an improved stacker wheel 300 for use in a media dispenser, for example as part of an automated teller machine (ATM). The improved stacker wheel 300 is capable of handling many different types of media including, but not limited to currency notes, tickets (e.g. train tickets), credit / debit cards and mobile phone top-up cards.

[0045] The wheel 300 has a central web-like hub 301 comprising a plurality of spokes 302 attached to an axle 303. Attached to the spokes 302 of the web-like hub 301 are a plurality of curved tines 304 (six tines in the example shown in FIGS. 3A-3D). Although the hub is shown in FIGS. 3A-3D as being web-like, it could alternatively be disk-like (i.e. a solid planar disk rather than discrete spokes). In use the stacker wheel 300 rotates about an axis of rotation 305 central to the axle 303.

[0046] The axle 303 is substantially cylindrical in shape and comprises a first portion 303a extending parallel to the...

Abstract

The invention relates to a stacker wheel for handling media, suitable for use in a media dispenser within an automated teller machine. The stacker wheel comprises a plurality of curved tines attached to a central hub. Each curved tine has a thickness that reduces with increased distance from the central hub over substantially the whole length of the tine, such that the spacing between adjacent tines increases with increased distance from the central hub over substantially the whole length of the tine.

Description

[0001] The present invention relates to an improved stacker wheel. It is particularly related to, but in no way limited to, stacker wheels for handling media in an automated teller machine (ATM). BACKGROUND OF THE INVENTION [0002] Stacker (or stacking) wheels are commonly used in automated teller machines (ATMs) to stack multiple currency notes prior to dispensing the stack of notes to a user of the ATM. The operation of a stacker wheel can be described with reference to FIG. 1 which shows a schematic side elevation view of a cash dispenser unit 73 of an ATM. The cash dispenser unit 73 includes a stacker wheel assembly 75. The stacker wheel assembly 75 comprises a plurality of stacker wheels 76 spaced apart in a parallel relationship along a shaft 77, each stacker wheel 76 having a plurality of curved tines 78. [0003] The cash dispenser unit 73 holds a number of currency cassettes 89 each holding a stack of currency notes 68. When one or more notes are to be dispensed from a particu...
