<p>PURPOSE:To adjust the reproducing speed and to improve the handling by detecting operating amts. of a variable speed lever and a variable speed dial and changing the reproducing speed in accordance with a detecting result. CONSTITUTION:A control data DCOMD is outputted by operating a fixed operator 2 from a corresponding command generating circuit 8, and a magnetic tape is reproduced at a speed which is decided by the operator 2. When the variable speed lever 4 is selected by selecting operators 6 and 32, a data SEN corresponding to a lever operating amt. is outputted from an operating amt. detecting sensor 10 via a selection circuit 30, and a command table 42 is accessed to obtain an output from a command converting circuit 40, and hence the desired reproducing speed is obtained. When the variable speed dial 24 is selected by the operators 6 and 32, an operating amt. data SEN1 is outputted from a rotating amt. detecting sensor 22 via the selection circuit 30 and the command converting circuit 40, so that the reproducing speed can be adjusted. When the variable speed dial 24 is selected, a rotary position data DKEN is generated by a data converting circuit 46, and an output data DSEN of a data memory 12 is renewed and initialized, and then a preset reproducing speed is maintained.</p> |
