Data handling system

Claim 1

A data handling terminal comprising: a microcomputer which is intended for connection to a central computer, and a memory, said data handling terminal (1) includes; feed path (5), intended for advancing a so-called time card (29); and along the feed path (5), a printer (19) and a sensor (21), said sensor being arranged to transmit a signal to the microcomputer (2) when a time card (29) occupies a pre-determined position relative to said printer (19); said data handling terminal also comprising a first control circuit (20) arranged to control said printer (19) in response to signals received from said microcomputer (2), and said data handling terminal further comprising an identifying device (22) arranged to read from a code device, a code individual to a respective employee; and wherein said microcomputer (2) is arranged to store in said memory (4), information corresponding to said employee code together with information printed by the printer (19), including the time concerned, the improvement comprising, in said data handling terminal, said sensor (21) which is arranged to transmit a signal when a mark, such as a spot (32-34), included on the time card (29) is detected by said sensor during passage of the time card along said feed path (5); and that said sensor (21) is arranged to transmit said signal to said microcomputer (2), which is thereupon programmed to transmit a signal containing information relating to the time in question to said first control circuit (20), said control circuit (20) being arranged to thereupon actuate said printer (19) so as to print the time concerned on the time card (29) together with a further correlated said mark spot (33;34), of the first mentioned mark spot type, which last mentioned mark spot is used for positioning the time card the next time the card is inserted into the data terminal whereby said last mentioned mark spot is sensed by said sensor (21).
