PURPOSE:To facilitate the easy sale of a ticket of an optional format by designating in common the ticket format when plural ticket vending machines are controlled by a central processor for the tickets of same type. CONSTITUTION:When a power supply is applied, both display memory DM and ticket format memory BFM are cleared. A ticket vending machine gives an IPL request to a central processor via a communication controller TCU and transmission line. An initial program given from the central processor is stored in a program memory PM. A means KI within a controller CTL reads out a prescribed code different from the screen data written to the memory BFM and decides a key input area. While a means DE within the controller CTL erases only the data in an area decided by a prescribed code different from the screen data when the prescribed data on the ticket format fed by a key is sent to the central processor. |
