Abstract
Abstract A recording head device comprises a roller, a recording head disposed opposite to this roller, a securing member, a frame with a hole, a pin passing through this hole in contact with the securing member, and a supporting means for supporting the recording head, having an elongate hole and being engaged by the pin between the securing member and the frame so that a small relative motion caused, for example, by deformation of the device is allowed between the securing member and the recording head and a uniform pressure can be maintained between the roller and the recording head.
