Abstract
The coin-type determining device, for determining the presence or absence of inclined notches formed on the circumferential surface of the coin transferred through a coin transfer path, comprises: a plurality of notch detecting devices provided separately from each other with respect to an axis of the coin; a determining device for determining the presence or absence of inclined notches based on the difference between the notch detection results by the notch detecting devices.
Claims10
A coin-type determining device for determining a presence or absence of inclined notches formed on a circumferential surface of a coin transferred through a coin transfer path, comprising:
- a plurality of notch detecting devices provided separately from each other in a thickness direction of the coin in the path, said notch detecting devices receiving light from a plurality of positions that are spaced in the thickness direction of the coin on said circumferential surface of the coin, so as to perform notch detection;
- a determining device for determining the presence or absence of notches inclined to said thickness direction based on a difference in phase between notch detection results by the notch detecting devices.
A coin-type determining device for determining a presence or absence of inclined notches formed on a circumferential surface of a coin being transferred through a coin transfer path, comprising:
- a light emitting device for emitting light onto the circumferential surface of the coin from a direction perpendicular to an axis of the coin;
- a plurality of light receiving devices provided separately from each other in a thickness direction of the coin to receive light reflected from the circumferential surface of the coin during transfer of the coin through the coin transfer path;
- and
- a determining device for determining the presence or absence of notches inclined to said thickness direction based on a difference in phase between notch direction signals from the plurality of light receiving devices.
