<p>PURPOSE:To prevent the peripheral parts of a loading mechanism from operating by estimating that a malfunction is caused in the case the number of rotations of a reel motor at winding side is less than the specific number of rotations and deciding it an error. CONSTITUTION:When an eject switch is pushed, a signal is transmitted to a mode motor driving circuit 5 from a system controllor 4, a magnetic tape is stopped when a mode comes in an eject state, and a tape guide is moved and shifted to an unloading motion. Now the number of feeding rotations of the winding side reel just before the stop is translated by the system controllor 4 and the specific number of rotations is decided. In the case it is less than the constant number of rotations, an abnormal signal is transmitted from the system controllor 4 and displayed on a screen. The damage of a tape can thus be prevented.</p> |
