Ticketing control unit

Claim 1

An automatic toll ticketing system for automatically providing tickets for billing toll calls, said system comprising memory means for recording ticketing information, ticket producing means operated responsive to computed information derived from said ticketing information, active ticketing control unit means for controlling said memory means and said ticket producing means and for providing said computed information to said ticket producing means, said active ticketing control unit means comprising storage means for receiving and storing said ticketing information including connect time and disconnect time, means in said ticketing control unit means for reading out said stored ticketing information, computing means for computing the elapsed time of a call from said readout information, means for supplying information representing said computed elapsed time to said storage means thereby reusing said storage means, means for supplying said elapsed time information to said ticket producing means, said storage means storing the ticketing information and the computed elapsed time information using a first code, translating means provided for translating said first code to a second code for use in computing said elapsed time, and for supplying said elapsed time to said ticket producing means, said storage means for storing the ticket information including connect time minute units digit storage means, connect time minute tens digit storage means, connect time hour units digit storage means, connect time hour tens digit storage means, disconnect time minute units digit storage means, disconnect time minute tens digit storage means, disconnect time hour units digit storage means, and disconnect time hour tens digit storage means, means including storage busses for selectively coupling said individual ones of said storage means to said readout means, means including said storage busses for disconnecting said readout means from said storage means and for connecting said storage means to said computing means, said computing means operating responsive to the simultaneous operation of said readout means, said translating means, and said means for connecting said storage means to said computing means, sequencing means provided for stepping said ticketing control unit to individually compute the elapsed time digits in the following sequence: minute units, minute tens and hour units, wherein converting means are provided for them converting the minute tens digit and the hour units digit to a total minute tens digit, hundred means provided for detecting and indicating when the total elapsed time minute tens digit is at least ''''10'''' and is less than ''''20,'''' and for detecting and indicating when the total elapsed time minutes tens digit is at least ''''20'''' and less than ''''30,'''' said first code being a two-out-of-five code, and said second code being a decimal code, said storage means including a set of five relays with two relays operated for each stored digit, said readout means including a set of five relays with two relays operated responsive to each readout digit, said translating means including a set of 10 relays, first contact field means comprising contacts on said readout relays for operating one of the 10 translate relays responsive to each of the operated two of five readout relays, and said computing means including a second contact field including contacts on said readout relays and said translating relays for extending an operating ground to reoperate selected storage relays to store the computed elapsed time digits.
