ABSTRACT:
Various signals are exchanged between a coin acceptor section that identifies the authenticity of deposited coins and sorts out the on the basis of their denominations, and a change control section that receives the sorted-out coins and performs control to count the coins and to deliver the coins as a change. Such a signal exchange between the two sections is achieved through optical coupling between a light emitting diode and a photo transistor, without employing any electric contacts. Further, electric power supply from the change control section to the coin acceptor section is done through spring-biased probes without employing any electric connectors, or through inductive coupling without employing any electric contacts. Such arrangements can greatly facilitate attachment and detachment of the coin acceptor section to and from the change control section.
