Definitions

  • An automatic fee determining system is provided with a real time clock associated with a storage register for recording in encoded form the identification of a given 15-minute time interval of the day.
  • a ticket issuer is positioned adjacent the entry lane of a parking facility to encode the entry time upon the ticket information from the real time storage register.
  • the information is encoded by passing the ticket beneath continuously energized tone heads which place BCD codes on the tickets. Switching of the signal to the tone heads in response to the position of the tickets at the issuer provides for multiple digit encoding in longitudinally spaced relationship on the tickets.
  • the tone heads are transversely [51] Int. Cl.
  • the present invention relates to automatic fee computing systems particularly for use in parking facilities and the like.
  • Some systems of the prior art provide minute-byminute computation of the time. This requires elaborate and expensive means for recording the time on an issued record, in reading the time from the record, and in computing the lapsed time on the minute-by-minute basis.
  • the present invention is predicated in part upon the concept of dividing the time of day into a plurality of discrete time intervals, which'intervals are sufficiently short to allow accurate computation of the elapsed time, but not so short as to require complete numerical computation capability to determine the elapsed time.
  • the present invention is further predicated upon the concept of providing an elapsed time and fee computation device comprising at least three digital storage registers differentially linked together so that one register will contain information representative of the difference between the values stored in the other two. Specifically, one register is controlled by a real time clock and contains information relating to the identification of the current specific time interval of the day.
  • the second register is controlled by a record reader so as to receive and store information relating ferential value in the third register is achieved by first setting the second register to the IN-time, as supplied by the record reader, and then by changing the value of the second registeruntil the information containedtherein corresponds to that of the first or real time register, to simultaneously make a corresponding change in the value of the third register, which change is representative of the number of elapsed time periods between, for example, entry and exit to and from a parking facility.
  • solid state circuitry forms the registers and the means for computing and comparing differentially the values to establish the elapsed time.
  • the registers are mechanical rotary switches linked together by a differential mechanical drive assembly.
  • the device of the present invention also includes an electronic fee computing device which assigns a fee based on the output of the elapsed time register, and also which communicates its value to a fourth fee register contained within an automatic pay station.
  • the output of the fee determining circuit may operate a-recording cash register for use by an attendant.
  • tickets are encoded magnetically as they are being issued by the placement of stationary tone heads adjacent a ticketfeeding path and to energize these heads as the tickets are passed beneath them to encode the tickets in longitudinal strips, preferably with BCD representations of the time of day at which the ticket is issued.
  • Plural elements of information are recorded by causing the data transmitted to the heads to be switched in response to the relative position of the issuing ticket with respect to the heads so as to encode upon the tickets different elements of data in longitudinally spaced relationship therealong.
  • Registration of the tone heads with respect to the ticket is achieved by providing a transversely floating head provided with an edge detecting guide and biasing means for moving the head until the guide is in contact with the edge of the ticket.
  • a separate channel is provided to one side of the ticket for detection by a reader at the exit lane. This channel is employed to determine the proper orientation of the ticket and also for determination of whether or not the ticket is validly encoded. The channel is so positioned that only one orientation of a validly coded ticket will result in proper detection of signal recorded on the channel. Improperly oriented or invalidly encoded tickets are rejected and returned to the customer.

  • the reader 21 reads the information encoded upon the ticket, which information is representative of the time at which the customer entered the lot, and transmits this information along a line or set of lines 22 to the computation module 13. If the customer has lost his ticket, he may depress a lost ticket button 23 on the reader panel which will transmit information indicating this fact along a line 24 to the computation module 13 to assign usually a maximum fee.
  • the ticket receiver unit 12 may, and preferably does, also include an automatic pay station 30 which includes a cash accepter 31 and also, if desired, a change return device 32.
  • the cash accepter accepts cash deposited by the customer and transmits information indicating the amount of cash deposited along a line 35 to the computation module 13. If change is required, the computation module 13 dispatches appropriate control signals along a line 36 to the change return device 32 which returns the proper change stored in a magazine to the customer.

  • the computation module 13 further operates to receive the encoded information from the ticket reader 21 on line 22 and to compare this information with the time period indicating the time of day at which the customer is leaving the lot, and then computes the number of time periods which have elapsed between the customers entry and exit to assign the proper fee to be charged the customer for the time for which he has used the parking area.
  • the computation module 13 additionally displays the assigmed fee to the customer. Payment of this assigned fee into the cash accepter 31 transmits signals along line 35 to the module 13 to cause to to operate the gate control 14 to permit the customer to leave the lot.

In the event that the ticket has been lost, a maximum fee charge would be entered in the register 54 through information received from line 24 from the lost ticket switch 23 and is input to the register 54 along line 55.
  • the information transmitted therefrom along line 35 is processed by logic 58 which generates the control signal on line 37 to operate the gate 14 when the amount of cash accepted corresponds to the fee as stored in the register 54.

  • the mechanism thus far discussed is a conventional difierential drive mechanism. Itis experienced with mechanisms of this type that considerable strain develops throughout this gear train so that when the motor 162 is ultimately stopped the residual stresses within the system will continue to apply motion to the output gear 238 which drives the switch register 161. With a 96 position switch, it is found that this forward motion or delayed motion is intolerable as it tends to move the switch off of its prescribed positions.
