SOLUTION: A first flat spring 31 and a second flat spring 35 are attached in an energizing region 30 formed in the rear of a frame 2. The first flat spring 31 and the second flat spring 35 are attached so as to surround a supporting shaft 15 with bends 32, 36 lapped. A head unit 20 is pushed to the platen roller 5 by an energizing piece 34 of the first flat spring 31, and the regulating member 16 is energized by the energizing piece 38 of the second flat spring 35, and then the platen roller 5 is prevented from coming out from the frame 2.
