ABSTRACT:
A paper sheet setting mechanism in a printer such as an ink jet system printer includes a memory device which stores a desired left setting position at which a left paper pressing roller should be positioned, and a desired right setting position at which a right paper pressing roller should be positioned. C-shaped guide plates are secured to the paper pressing rollers. Each of the C-shaped guide plates includes a roof member which is made contact with a pritrusion secured to a printer head when a shaft of the paper pressing rollers is held at a first stable position. When the printer head is driven to shift while the shaft is held at the first stable position, the paper pressing rollers are shifted on the shaft and controlled to be positioned at the desired left and right setting positions, respectively.
