Abstract: 1,221,218. Ticket gates. TATEISI ELECTRONICS CO. 23 Sept., 1968 [29 Sept., 1967], No. 45121/68. Heading G4T. A system for automatically examining railway tickets and operating gates according to the information encoded thereon comprises a plurality of ticket gates each having means for reading the information and means for operating the gate, means connectable to any one of the gates to co-operate with the gate's reading means to examine the information read, whereby the gate is operated to permit passage therethrough only when the information is valid, while the gate operating means of the other gates are conditioned to permit passage therethrough regardless of the validity of the ticket used. Each ticket gate, Fig. 1, comprises pivoted bars 15, 25, at the exit end and passenger detectors operated by light beams 34. There may be a floor mounted weight operated detector 36. A ticket inserted at 22 activates a conveyer which conveys the ticket past a reader to an exit slot 23. Each gate may be either normally open or closed. In a first embodiment, Fig. 2, the units within the box 70 form a detachable section connectable to any one of the gates. The ticket information is memorized, 51, and compared with the correct information by a collation circuit 52. If the ticket is valid the circuit 52 produces an output which is stored in a memory 53, and an inhibit signal is applied therefrom to a gate driving circuit to prevent the gate being closed by the passenger detector 47. The other gates will remain permanently open. In a second embodiment, Fig. 3, the gates without a detachable section 80 will not close provided a ticket is detected, but regardless of the information thereon. In the gate with the section 80 attached, a switch 90 is set upwards so that the gate driving circuit 55 is inhibited when the ticket information is correct. The switch 90 is otherwise set downwards so that activation of the ticket detector 42 inhibits the circuit 55. In a third embodiment, Fig. 4, the gates are normally closed, and those without a detachable section 80 will open when the ticket detector 42 is actuated together with the passenger antenna detector 47, a switch 90 being set downwards previously. The gate driving circuit 155 is effectively an " AND " gate. With the section 80 connected, switch 90 is set upwards to utilize the ticket reader 40 instead of the ticket detector 42. The gates are closed upon actuation of a passenger passage detector 46, e.g. a plate 36, Fig. 1. Further embodiments are described wherein a detachable section corresponding to box 70, Fig. 2, or box 80, Fig. 3, is sited at a remote location where it is selectively connected to one of the gates by ganged rotary switches or ganged rotary switches which open a selected solenoid-operated switch, the solenoidoperated switches corresponding to the switches 90, Fig. 3. The ganged rotary switches may be operated manually or automatically. Finally, the remotely located detachable section may be connected to each gate in turn by a circuit arrangement including a counter, driven by a slow or rapid pulse generator. The counter is halted by an output from the detachable section on serving a valid ticket, Fig. 9 (not shown), or merely detecting a ticket in the associated gate, Fig. 10 (not shown), the counter being re-started in each case when the ticket checking is completed.
