PURPOSE: To enable even an inexperienced customer to smoothly purchase the commodities with no prescription of the input sequence by optionally granting the corresponding input sequence when the customer inputs a designated item for purchase of the desired object.
CONSTITUTION: A CPU 31 controls each circuit device based on the program stored in a ROM 32 and stores these control data in a RAM 33 so that they can be freely read out. Then the CPU 31 does not prescribe the input sequence for operations of a destination station selection button 17, an equipment button 18 which selects the reserved seat tickets, the non-reserved seat tickes, etc., a touch panel switch 21 containing a display which shows the designated fare for purchase of a ticket and also performs the touch input operations, etc. Thus the input operations are granted in an optional sequence. Furthermore the CPU 31 shows the due input items which are not inputted yet by the customer on a guidance display 13 while the designated purchase items are received in an optional sequence.
