Claims

[Scope of utility model registration request]

A printing arm 4 whose base end is supported by a machine frame 2 on a base 1 so as to be swingable in the vertical direction by a shaft 3; A shaft 9 with a support arm 8 at each end with an adjustable adjustment lever 10,
12 to support the adjustment lever 10 so that it can be vertically raised and lowered, and the printing block 5 is attached to this support arm 8.
A cam 22 of a cam device 6 that swings the printing arm 4 in the vertical direction is engaged with the printing arm 4, and a printing drive spring 7 that pulls the printing arm 4 toward the base 1 to perform printing is engaged. The cam 22 of the cam device 6 has a maximum radius area 22A that pushes the printing arm 4 to the highest position, and a slowdown area 22B that connects to this area and brings the paper presser 20 of the printing block 5 into contact with the paper. , a step portion 22G that continues from this region and has a required head difference, and a return region 22E that continues from the bottom 22D of this step portion to the maximum radius region, and by changing the head of the step portion 22C, the printing block 5 can be adjusted. A printing machine characterized in that the lifting height of a type block is changed and printing is performed by the traction force of a printing drive spring 7.
