Abstract: 1,238,908. Car parks. S. A. KROLL. 5 Sept., 1968 [7 Sept., 1967], No. 42233/68. Heading G4T. A car park has a register 38 at its exit adapted to receive a time-stamped parking ticket whereby a parking fee entered on the register keyboard by a cashier is imprinted on the ticket and displayed on an indicator board 40, and an audit recorder located at a central station for totalling the parking fees charged at the exit and the number of cars leaving the car park and recording on an audit strip the total parking fees charged and number of cars leaving the car park at predetermined intervals, on demand, or for every transaction. In addition, a print-out is obtained automatically on a malfunctioning of the system. An audit recorder is provided for each exit or a single audit recorder is provided for a plurality of exits. As illustrated in Fig. 6, detectors 14a, 14b and ticket issuing machine 16 in the entrance 10a apply signals to AND gate 27, when a car is in the entrance and a ticket is taken from the machine 16, to operate traffic signals 18 and inhibit gate 25 preventing generation of an alarm signal. Likewise, detectors 42a, 42b and register 38 in the exit 10b apply signals to AND gate 47, when a car is in the exit and a ticket inserted in the register, to inhibit gate 45. If a car passes through the entrance or exit without stopping or passes through the entrance or exit in the wrong direction whereby sequential relay 31 or 35 fires, then an alarm signal is generated and a print-out obtained. On inserting a ticket in the register, switch 49 is closed to energize print hammer 84 which in turn closes switch 53 applying a signal to AND gate 47. The register is primed by a cashier's key 85 closing a switch 89 in the circuit of switch 49 and a switch 91 to energize the audit recorder whereby a print-out is obtained at the start of a cashier's tour of duty. A switch 57 is closed to print a receipt. The register comprises a plurality of setting levers 50a, Fig. 2, positioned according to the amount to be charged to selectively position wafer switches 60a, controlling the indicator board 40 and providing the input to the audit recorder, and position printing wheels 66a. Commonly occurring amounts may be set up on the register by a single setting lever. Additional printing wheels record the date and time. The cashier's key 85 carries an embossed number printed on the ticket. In a second embodiment, Fig. 8, the cashier initially inserts his key together with an attendance card in the register to set flip-flops 115, 116 and 119 and generate a "lane open" signal causing the audit recorder to print out the cashier's identity number entered on the register keyboard followed by the total stored therein. The total store is cleared and a second total printing cycle initiated by flip-flop 126 to print out a zero total followed by a time print 128 after a predetermined delay. A car is sensed at the exit by a single detector 111 to generate a "car present" signal which together with "lane open" and "ticket in" signals operate the register to record the amount set up on the keyboard 143 and enter the amount in the central store. If the car passes the detector without stopping, gate 155 fires to trigger the alarm 156 and causes the audit recorder to print an X followed by the subtotal 132 and time 128. If a car driver hands over his ticket and the correct amount but does not stop, the cashier enters the amount by closing switch 158. On completing his tour of duty, the cashier sets up the date on the keyboard, removes his key and inserts his attendance card to generate a "lane closed" signal whereby the printer prints a "C" followed by the sub-total and time.
