Front - and rear side of a time control card discriminating apparatus, equipped with the same time recording means, a method for distinguishing - from the front and rear side of the time control card and program

摘要

A time recording device (10) has a first sensor (15), of the lateral edge of a time control card, which has a cutout of the at least at a lower corner is formed, a second sensor (16), which the lower end of the time control card is detected, and a cards intake factory (28), which draws the time control card. If the time control card of this cards intake factory (28) is drawn in, includes a pulse counter of the cards feed mechanism (28) the number of pulses of predetermined pulse signals, after the first sensor (15) has detected the time control card and to the second sensor (16) detects the time control card. As the next step, front - and the rear side of the time control card on the basis of the number of pulses is determined, which a count is. Consequently, it is possible, front - and the rear side only by means of the first sensor (15) and of the second sensor (16) to determine. Accordingly, the device can have a simplified structure.
