PURPOSE:To obtain the titled device being excellent in durability and causing little noise by making the hammer retained in a standby state for printing by a deep retaining part when the high reset part of a reset cam pushes up the hammer and by making a shallow retaining part work when the low reset part operates. CONSTITUTION:At least one reset part is made to be the high reset part 20a, and when this high reset part 20a pushes up the hammer 12, the hammer is retained in the standby state for printing by the deep retaining stage 42a. The collision and contact of other low reset parts 20b and 20c with the hammer 12 can be removed and the abrasion and the generation of noise in each part can be reduced. |
