PROBLEM TO BE SOLVED: To make a die appear to make smooth motions at the start of motions. SOLUTION: The display comprises a housing 20 rotatably supporting the die 10, a pulse motor 30 as a rotation driving source for rotating/operating the die 10 so that each face of the die 10 is at a display position successively, a motion converting mechanism 40 for converting the rotating motion of the pulse motor 30 to the rotating motion of the die 10, and a control part 70 for controlling the rotation of the pulse motor 30 by generating pulses necessary to rotate the pulse motor. The control part 70 has a function of starting the pulse motor 30 with such a speed pattern like a primary curve that the die 10 can follow and rotate. COPYRIGHT: (C)2005,JPO&NCIPI |
