[banknote output control device with prevents supply of stacked banknotes]

Abstract

Disclosed is a banknote output control device, which includes an optical transmitter module controlled to emit light across the banknote delivery path, an optical receiver module controlled to detect light passing from the optical transmitter module across the banknote delivery path, and a control circuit, which continues the output of a banknote when the value of the detected signal from the optical receiver module is approximately equal to the predetermined reference value, or reverses the banknote delivering direction when the value of the detected signal from the optical receiver module differs from the predetermined reference value significantly.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a banknote output control device for use in, for example, a money exchanging machine and more particularly, to such a banknote output control device that prevents supply of stacked banknotes. [0003] 2. Description of the Related Art [0004] Following fast development of high technology, a variety of auto vending machines (such as ticket vending machines, money exchanging machines, etc.) have been developed and intensively used in public places, stores, and etc. In an auto vending machine, a banknote (ticket) output control device may be used to automatically output banknotes (tickets). Because a banknote (ticket) has a thin thickness, two or more banknotes (tickets) may be carried together for output erroneously. [0005]FIG. 8 shows a banknote output control device A according to the prior art. According to this design, the banknote output control device A comprises a chamber A1, a gap...

Benefits of technology

[0007] The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a banknote output control device, which prevents supply of stacked banknotes. To achieve this and other objects of the present invention, the banknote output control device uses an optical transmitter module to emit light across the banknote delivery path, an optical receiver module to detect light passing from the optical transmitter module across the banknote delivery path, and a control circuit to control the out

Problems solved by technology

Further, because a banknote C has a thin thickness, it is difficult to adjust the banknote delivery gap to the thickness of the banknotes C accurately.

If the banknote delivery gap is not equal to the thickness of the banknotes C, two or more banknotes C may be delivered together, or banknotes C may be jammed in the gap control device B, resulting in failure of the whole system.
