  • Front/back discrimination device for time card, time recorder provided with same, front/back discrimination method for the time card, and program
    Patent number: 8941699
    Abstract: A time recorder includes a first sensor that detects the side edge of a time card having a cut-out formed at at least one corner of the bottom, a second sensor that detects the bottom of the time card, and a card feeding unit that feeds the time card. When the time card is fed by this card feeding unit, a pulse counter of the card feeding unit counts the number of pulses of predetermined pulse signals after the first sensor detects the time card and until the second sensor detects the time card. Next, the front and back faces of the time card are determined based on the number of pulses that is a counting result. Hence, the front and back faces can be determined by the first sensor and the second sensor only.
