<p>PURPOSE:To detect each housing position as an absolute position by providing a driving means which operates the combination of ON-OFF of first and second position detecting devices before and after movement at the time of moving between positions so as to be set differently from each other in respective position. CONSTITUTION:In the first and second position detecting devices 21 and 22, through holes are provided at positions shown in figure on a gear 6. At the time of moving a disk reproducing mechanism 3 in a perpendicular direction, that is, rotating the driving gear 6, the combination of the change of the output of the first and second position detecting devices 21 and 22 at the time of moving from a certain disk housing position to an adjacent disk housing position can be set differently in all disk housing positions. Thus, the present position of the disk reproducing mechanism 3 can be recognized up to 6 stages at maximum, and furthermore, by constituting and distinguishing the output of the first and second position detecting devices at a first disk housing position differently from another disk housing position, it is possible to set it as a reference position.</p> |
