Abstract: A conventional disc changer uses separate elevating cams, separate connection mechanisms, and separate locking mechanisms to effect driving of the elevation and lowering of spindles constituting a disc holding means and of a disc clamp means at a recording/playing position. Thus, the apparatus is complicated and large, and loads on the elevating cams significantly vary when the drivings of the elevating and lowering of the spindles constituting the disc holding means and the disc clamp means are simultaneously carried out.

According to the present invention, an elevating means for elevating and lowering the spindles constituting the disc holding means and a disc playing means is configured so that a single part simultaneously performs these operations.

In contrast, when the decision result indicates that the measurement value is less than the threshold value, the CPU does not authorize the mobile station to transmit the message.
