Abstract
There is disclosed an electronic display unit wherein a motor driving portion including a CPU and a driving IC controls a drive current to a motor (11) so that the motor (11) initially rotates at a low speed and subsequently rotates at a high speed to switch the speed of rotation of a case (3) from a low speed to a high speed, whereby operability is ensured if a rotation control switch is disposed on a front surface of the case (3), preventing conventionally increased size of the unit as well as alleviating user's feeling that rotation requires too much time.
