PURPOSE:To shorten the switching time of a display screen by previously preparing picture information having high probability of display at the time of using a season ticket issuing machine. CONSTITUTION:In the season ticket issuing machine, a storage device 15 is constituted of plural frame memories 15a to 15n. Data writing in respective frame memories 15a to 15n is started before determining the contents of a transaction or picture information to be displayed next. For instance, in the display state of a guide 'input of effective period' on the display screen 11a, the contents of plural picture information for displaying 'purchased amount', 'input of name', 'input of age', 'input of sex', etc., are stored in individual frame memories based upon the priority order of the picture information during the input of the effective period. At the time of determining the contents to be displayed, one of the frame memories 15a to 15n is selected and a display on the display screen 11a is switched. |
