Claims

[Scope of utility model registration request]

A head support member that supports the head is supported on the chassis so that it can freely rotate in the direction in which the head approaches and leaves the recording sheet, and can also move along the recording surface of the recording sheet. A cam surface is provided on one side of the swing end side and the chassis, and a movable body that moves along the cam surface is provided on the other side, and the cam surface has a portion corresponding to the recording or reproducing area of the movement area of the head. The flat part is parallel to the recording sheet, and the part corresponding to the area outside the recording or reproduction area is an inclined surface, and when the movable body comes into contact with the inclined surface, the head leaves the recording sheet. A head support device characterized by:
