1. The electronic block system of a ticket puncher is designed for determining ticket validity. Characterized in that: It is equipped with a microprocessor controlling system (A), connected to the operation-mode configuration module (D) with the clock (J) and a non-volatile memory. It is also connected to the local keyboard module (K), used for defining a digit sequence, the clock used in autonomous mode, the A/V signalling module (L), the display module (C), the transmission module (E) which communicates with superior controllers, and the sensor module (F) for controlling the status of the module of actuators (B).
