A detector housing and a photosensor are provided. The sensor interactive portion has an aperture of a predetermined size. The detector, particularly the body, is reciprocally mounted in the housing, whereby the card contacting portion of the detector contacts the uppermost card of a deck of cards and the sensor interactive portion is received in the photosensor. Depending on the sensed position of the card contacting portion of the detector, the machine receives a reshuffle or proceed command.
