PROBLEM TO BE SOLVED: To provide an automatic issuing machine capable of positively communicating operation guidance by speech. SOLUTION: Right before a ticket vending machine generates the operation guidance by speech, a "ping pong" sound is generated to call attention of a user. By this, the user will not miss the first word of the substantial vocal guidance. COPYRIGHT: (C)2006,JPO&NCIPI
