Bill Stacker Detection Apparatus

Abstract

A bill stacker detection apparatus comprises a base body, a stacker and a sensor. The sensor has a light emitting element and a light receiving element. When the stacker is moved to a position near the sensor, apertures of a protruding structure on the stacker is covered. The light receiving element is unable to receive a light beam emitted by the light emitting element. If bills fill with the stacker, a bill supporting plate then pushes a sliding block. The aperture is staggered by the sliding block. The light receiving element then receives the light beam to detect whether the stacker is disposed on the base or filled with bills.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a bill stacker detection apparatus, and more particularly to the bill acceptor detection apparatus that performs the positioning detection, and detects whether a stacker is filled with bills.BACKGROUND OF THE INVENTION[0002]Coin acceptors of vending machines usually adopt coins and bills. The design of bill acceptors currently does not focus on the positioning of bill acceptors and bill acceptors filled with bills. Some companies then use counters, photoelectric switches, micro-switches or magnetic elements to detect the positioning of bill acceptors and bill-full status. However, the aforementioned ways still have the following shortcomings:[0003]1. If the counters are used to count whether or not bills stored in the bill acceptors are full, the circuit design may not easy It is also difficult to maintain when it is in malfunction.[0004]2. If the photoelectric switches are used for detection, the sensing areas may be easi...

AI Technical Summary

Benefits of technology

"The present invention provides a bill stacker detection apparatus that can determine if a stacker is full or not. This is achieved by using a sliding block that covers the apertures of a protruding structure on the casing of the stacker when the bills are not full. When the bills are full, the displacement of the bill supporting plate pushes the sliding block, exposing the apertures and allowing the light receiving element to receive the light beam, thereby detecting if the stacker is filled with bills. This apparatus provides accurate positioning detection and ensures the efficient operation of the bill stacker."

Problems solved by technology

However, the aforementioned ways still have the following shortcomings:1. If the counters are used to count whether or not bills stored in the bill acceptors are full, the circuit design may not easy It is also difficult to maintain when it is in malfunction.

2. If the photoelectric switches are used for detection, the sensing areas may be easily covered by dirt to generate errors, and component costs are high.

The contacts may easily generate damages after use for a while.

When the bills stored in the bill acceptors are full, predetermined alarm lamps then shine and then electrically conducting circuits are cut off However, magnetic forces may disintegrate after use for a while.

Alternatively, detection actions may not be certainly performed.

Besides, because there are metal components and electronic components disposed in the coin machines, the reed switches may be inappropriately influenced to cause inaccurate detections.
