Abstract
A tape recorder having a controller for a movable member is able to control the movement of the member between two states by one electromagnet. The controller includes an electromagnet having first and second attracting parts which correspond to first and second attracted parts, a driving member which is driven through a fixed motion by a driving source, a combining part for moving which is installed on said movable member so as to separate from the driving member or be maintained in the combined state with said driving member by said first attracted part, a combining part for keeping position which is installed on said movable member to maintain said movable member in the second position by combining with the second attracted part and a leaving prevention part for preventing the leaving from said driving member of said combining part for moving when said movable member is at a position from halfway between said first and second positions to its second position. A separating part which is installed on said moving member or on said combining part for moving, can pull apart said first attracted part forcibly from said first attracting part after said combining part for moving has reached said leaving prevention part by movement of said movable member from said first position toward said second position and also before said part reaches said second position.
