PURPOSE:To contrive to enhance the efficiency of disassembling and assembling operations, by providing a means for preventing a lever part from being drawing out by an attracting force of a permanent magnet when disassembling a wire- driving mechanism, in a wire head type printing head. CONSTITUTION:When disassembling, a driver is inserted through a hole 18 provided in a head cover 3, a screw 17 provided with a pressing-in plate 16 is fitted in, and the lever part 5 consisting of a lever body 6 (provided with the printing wire 4), an attracted member 7 and a screw member 8 is fixed by pressing against a head frame 1 and a guide frame 2. Thereafter, when the head cover 3 provided with the driving mechanism 10 is detached from the head frame 1, the lever part 5 remains as it is without being drawn out. Accordingly, since the printing wire 4 can be disassembled while remaining inserted in the guide frame 2, the efficiency of the assembling and disassembling operations can be enhanced. |
