Claims

[Claims for Utility Model Registration] (1) A printing device that prints using a print head that reciprocates along a print line on printing paper, comprising: a driving means attached to one side of a frame corresponding to one end of the print line; , a driven means attached to the other side of the frame corresponding to the other end of the printing line, and a connection stretched between the driving means and the driven means and partially attached to the printing head. and a bearing means that is attached to the other side of the frame corresponding to the driven means, and is formed with a number of support parts each having a different distance from the driving means and rotatably supports the driven means. A printing device characterized by: (2) The printing device according to claim 1, wherein the support portion is a recess opened outward in the extending direction of the other end of the print line, and is formed in large numbers in a step-like manner. (3) The bearing means has a surface that comes into contact with the frame on the opposite side of the recess, and is attached to the frame so that the position of the bearing means with respect to the frame can be changed along the direction in which the recesses are arranged in a stepped manner. The printing device according to claim 2, which is provided with a latching means for selectively latching the printing device. (4) The driven means has a shaft protruding in both directions of the rotational axis, and the bearing means has a hole in the center of which the driven means is disposed and through which the connecting means passes;
The printing device according to claim 2, which has the recess for supporting the shaft on both sides of the hole.
