<P>PROBLEM TO BE SOLVED: To vary the pressing stroke of a button by a simple structure. Ž<P>SOLUTION: A transfer restraining plate 50 is disposed under the presentation button 24. A stopper 24b is formed in the presentation button 24, and an abutting part 50a is formed in the transfer restraining plate 50. The transfer restraining plate 50 is slidably retained between a restraining position to insert the abutting part 50a into the transfer pathway of the stopper 24b and a permitting position to retract the abutting part 50a from the transfer pathway of the stopper 24b, and is driven by a solenoid 56 to slide/move. When the transfer restraining plate 50 is moved to the restraining position, the stopper 24b abuts on the abutting part 50a in the process of pressing the presentation button 24, so that the presentation button 24 can not be pressed to the last. When the transfer restraining plate 50 is moved to the permitting position, the presentation button 24 can be pressed to the last without the stopper 24b abutting on the abutting part 50a.
