Abstract: 1,110,381. Checking fares. J. W. HALPERN. 26 March, 1965 [27 March, 1964], No. 8147/64. Heading G4T. A fare charging apparatus for a public transport system comprises an entry registration unit whereat a token is issued recording the entry fare stage and an exit registration unit in which the tokens are placed to assess the journey of the passenger and display the fare payable. A passenger may previously obtain a pre-paid ticket or a ticket with an account number for future rendering of an account which is inserted in a second entry registration unit for recording the entry fare stage. When used at stations, separate entries and exits are provided for the ticket-holding and non- ticket-holding passengers. At an entrance to a bus, closure of a button 13 (Fig. 3) releases a ticket in a shoot 14 wherein erasing heads E2 erase any characters on the ticket and writing heads W2 write numbers from registers ZS2 and VCS1, corresponding to the entry zone number set by the driver on a switch ZSW and to a vehicle check number set on a switch VCSW, through a modulator M1, a correction unit C2 which compensates for the orientation of the ticket, and a pulse sequencing unit PS1. Ticket holders insert their tickets in a slot 18 wherein reading heads read the ticket value and a check number which is recorded after demodulation D1 and correction unit C1 in registers VS1 and CS1 respectively. The check number is compared CC1 with a stored check number and if found invalid a lamp L1 is illuminated and a penalty fare number is transferred from PN together with the entry fare stage number ZS 1 to a subtraction SB 1 for subtraction from the ticket value number VS1 and entry in a register VS2. The entry fare stage number represents the fare from the entry point to the terminus. If the ticket is valid the penalty number PN is omitted. Erasure heads E1 erase all characters except an account number from the ticket and writing heads W1 write ticket value number VS2, entry zone number ZS2 and vehicle check number VCS1 on the ticket. At the exit point the tickets are inserted in a slot 22 (Fig. 4) wherein reading heads R2 read all the information on the ticket and the account number is transferred to a register TS, the ticket value number, entry zone number and vehicle check number are transferred to registers VS3, ZS3 and VCS2 respectively and the check number compared with that in register CC2, disagreement causing illumination of a lamp L3, operation of an alarm bell AL and ejection of the ticket. The exit zone number representing the fare from the exit point to the terminus is set in register ZS4 by the switch ZSW, added AD to the value number VS3 to indicate the final ticket value number VS4, and subtracted SB2 from the entry zone number ZS3 to fine the fare number CNS which is displayed DU. The ticket value number VS4 and a correct registering signal CS2 are written on the ticket by writing heads W3. If an account ticket is used the account number T3 is recorded on a tape REC and a renewal number VS5 added to the ticket value number, if the final ticket value number VS4 is negative. In a modification, successive fares are added to the ticket value number until the ticket value number exceeds a predetermined limit, whereupon the account number is recorded and the ticket value number reduced by a fixed amount. If the value of a pre-paid ticket becomes negative it may be renewed in a similar manner by payment to the driver or an automatic machine. The casual tickets inserted in the exit unit are transferred pneumatically to the entry unit for re-use. The entry and exit units may be coupled to count and control the number of people on the bus. Different rates of charging may be in operation at dfferent times of day. Several shoots may operate at each operation apparatus although controlled by a single computer.
