Abstract

In a portable small size printer unit 1, when a pickup roller 50 is replaced, user grips a roller main body 55 and slides it resisting a bias force of a spring 57. Consequently, when the roller main body 55 is slid, the entire length of the pickup roller 50 is shortened, so that a first convex portion 55c is removed from a first concave portion 51a. After that, the front end of a slide shaft member 58 is removed from a shaft mounting portion 42a by tilting the roller main body 55 and then, the pickup roller 50 is removed from the printing mechanism unit 7. By sliding the slide shaft member 58 outward of the roller main body 55, the roller main body 55 is taken out of the slide shaft member 58 and the like so as to replace only the roller main body 55.
