PURPOSE:To simplify a circuit configuration by providing a pause zone generator for setting at every drive signal, thereby enabling to combine the signal of pause zone with four diodes and the drive signals. CONSTITUTION:A pause zone generator 6 for setting zone that a pair of drive signals of reverse phase relation become together OFF at each pair of drive signal is provided, and outputs of NAND circuits N1, N2 of the pause zone generator are connected to corresponding drive signals A, -A, B, -B of a ROM5 through diodes d1-d4. A switch SW is connected to a (a)-terminal side in case of normal rotation, and connected to a (b)-terminal side in case of reverse rotation. |
