PURPOSE:To eliminate the need for strictness for adjusting the position of the supporting point for respective parts, by integraly providing a positioning unit with a recording head and positioning a feed roller based on the positioning unit. CONSTITUTION:A slit 5a is formed at the tip portion of an arm 5 and the shaft 6 of a feed roller 3 is inserted into the slit 5. In addition, a pin 10 is mounted at the side near to the root of the arm 5 and a spring 11 is disposed between the pin 10 and the shaft 6 so that the feed roller 3 is pulled toward the root side of the arm 5 at all times. The recording head 4 has a positioning plate 12 provided at its both sides in a lengthwise direction and the shaft 6 of the feed roller 3 is locked within a positioning cutout 12a. Thus, since the recording unit 4a of a recording head 4 and the cutout 12a are located at the same position at all times the feed roller 3 is pressed to the recording unit 4a at an accurate position. Therefore, it is not necessary to so strictly position the shaft 6 and shafts 7, 8, whereby assembly can be made readily.
