Abstract

PURPOSE:To enable the normal printing, to have the long duration of a lever stop part and to enable the acquisition of shock absorbing property even after a long period of stoppage, by jointly using a metallic spacer and a rubber spacer for the lever stop part. CONSTITUTION:The metallic spacer 8 having a hardness of 500min in Hv and a rubber spacer 7 are jointly used for a lever stop part. The core part of a frame 1 is magnetized by applying current to a coil 13 and an armature 6 is attracted. A lever 9 is rotated following that and a wire 10 is pushed. Paper is printed by its top via an ink ribbon. When the application of current is stopped, the lever 9 is pushed back by the force of a returning spring 11 and collides with the lever stop part consisting of the metallic spacer 8 and the rubber spacer 7. After rebounding, it is stopped. Though the lever 9 is always pushed onto the metallic spacer 8 by the force of the returning spring 11 during long time stoppage, the lever 9 normally prints the first dot without boring into the metallic spacer 8 at the start of motion. Further, the metallic spacer 8 with which the level directly collides does not lose its function even after its use for a long time.

Conventionally, a rubber spacer 7 is placed inside the lever holder 5θ at 11I11, and a thin layer is placed on top of the straddle rubber spacer 7 to specify the stroke length of the lever 90 and to absorb rebound when the lever returns 0 after printing. It had a structure that incorporated a plastic spacer.

If only rubber spacer 7 is used, return spring I when stopped for a long time
l+ 17) Lever 9 tends to bite into rubber spacer 7 due to force, so V) When starting lo, energy is used to move lever 9 away from rubber spacer 7, so it is normal. There is a problem that it cannot be printed on. In order to eliminate biting, a rubber spacer 70 and a plastic spacer with VC scratches are used, but the lever 90 wears out due to the impact force of the lever 90 returning and breaks when used for a long time. There is a problem with putting it away.

The impact dot head that has been drilled as shown in ■ above is
Long) When υ1 is stopped, the lever is in contact with the metal spacer and does not bite at all. Therefore, the first dot can be printed normally even at subsequent startups. In addition, since it is made of metal, rubber is more abrasion resistant than plastic, making it more durable. Furthermore, by giving the metal spacer a unique shape that reduces rigidity, it is possible to take advantage of the shock absorption properties of the rubber spacer.
