Abstract: In a magnetic tape device including a cam, an operating member driven by the cam against force of an energizing member to bring a head to a position for press-fitting a tape, and a changeover member actuated by the cam for changing tape feeding direction, an improvement which comprises an electromagnetic plunger, a control member for linking the cam and the operating member to actuate the operating member in press-fitting position upon energization of the electromagnetic plunger and for releasing transmitting relation between the cam and the operating member both in the press-fitting state and in the middle of the press-fitting action upon deenergization of the electromagnetic plunger, and a link member for linking the cam and the changeover member during action of the operating member, thus not cancelling transmitting relation between the cam and the changeover member even if the action of the operating member is cancelled during action of the changeover member.
