持される。 Since the present invention has the above-described configuration, printing by the line printer 1 is performed by rotating the type belt 16 in the E direction and also circulating the ink ribbon 21, so that the hammer printing surface 6 of the printing hammer 6 is rotated.
A is selectively driven to project in the direction of the type belt 16, but in order to obtain good printing, as already mentioned, the type belt running surface KBF of the printing unit 5 and the hammer printing surface of the printing hammer 6 must be It is necessary to adjust so that the hammer surface PHF on which 6a is aligned is in a parallel state. This adjustment is performed by moving the positioning cams 9, 9 on both sides of the belt unit 3 by arrow C while the printer 1 is in the printing operation.
Rotate in direction D. Then, the cam surface 9
a. Belt unit 3 via positioning pin 2a
moves in the directions of arrows A and B with respect to the base unit 2 while being guided by the guide groove 3b, and moves on the running surface.
The gaps GAP1 and GAP2 at both ends of the unit between the KBF and the hammer surface PHF change. By appropriately operating the cams 9, 9, adjust the gaps GAP1, GAP2 so that GAP1=GAP2, that is, so that the printing condition of the printout printed by the printer 1 is the best. When the adjustment is completed, , fix the cam 9 to the unit 3 by tightening the fixing bolt 10, and set the gaps GAP1 and GAP in good printing condition.
Hold 2. Therefore, the fixing metal fitting 11 is further rotated in the C direction to engage the pin 2a in the engagement groove 11a, and in this state, the fixing bolt 12 is tightened to engage the belt unit 3 with respect to the base unit 2. When fixed via the groove 11a and the cam surface 9a, the gaps GAP1 and GAP2 are fixed and held in the best printing condition.
