    摘要: A head shift mechanism in a magnetic tape apparatus includes a rotatably driven gear, a movably supported engaging member intermittently engageable with the gear, and a cam member which is operatively coupled to and moves simultaneously with the engaging member. A movably supported changeover member is cooperable with and moves in response to movement of the cam member, and a selectively actuable arrangement causes the gear to drivingly engage the engaging member. A movably supported operating member has a magnetic head thereon, and the changeover member can cause a movably supported control member to move the operating member to an advanced position. A lock arrangement is provided to releasably lock the control member in a position where it holds the operating member in the advanced position, and selectively actuable release arrangement is provided for releasing the lock arrangement.
