<p>PROBLEM TO BE SOLVED: To make a control for moving a record medium and the control of initializing operations to be surely performed even when the count value of a counting means is in-definite by producing positional information for control becoming the same value even when the counting means is initialized at a first transfer position or a second transfer position. SOLUTION: When a counting means is initialized at a refernce position (A position), a count value (the value of a pulse counter) is made to be positional information for control and when the means is initialized at the transfer position (B position) of a side different from the side of the reference position, a value in which a count value equivalent to the distance between the first transfer position and the second transfer position is added to the count value of the means is made to be positional information for control. Consequently, even when the means is initialized at both of the A position and the B position, positional information for control becoming the same value can be obtained. Then, this information can be used in various kinds of controls as reliable positional information at the time of the turning the power on.</p> |
