Device for actuating a closure element of an input/output opening of a read/write unit for data cards

摘要

The operable coupling between the input of a data card (6) and the operating of the closing element (27) is arranged in such a manner, that as well as having a high functioning reliability on the one hand, also the possibility of substantially preventing any unauthorised manipulation of the operable connection on the other hand. A light barrier works in conjunction with the push rod (33) so that a signal is transmitted designating the read-recording position of a data card. One of the two side walls (5) forming the guide shaft is used for the location of the push rod.
