ABSTRACT:
A power transmitting device for a stepping motor comprises: a stepping motor commonly serving as a power source for a pickup moving mechanism of a light load and a power source for a disk transferring mechanism of a heavy load; switching mechanism for a switching path for transmitting the power from the motor between the first path, via which the power is transmitted to the pickup moving mechanism, and a second path, via which the power is transmitted to the disk transferring mechanism via power transmitting gear mechanisms; and transmission prohibiting mechanism for prohibiting the transmission of the power from the stepping motor to the disk transferring mechanism at the beginning of the power transmission via the second path.
