ABSTRACT:
A sheet setting device for a printer and the like including pressure rollers adapted to be brought into and out of engagement with a platen, and resist claws adapted to brought into and out of engagement with the platen in a position downstream of the position in which the pressure rollers are brought into and out of engagement with the platen. The device includes an operation lever and a linkage for linking the operation lever with the pressure rollers and the resist claws, the linkage being constructed such that as the operation lever is actuated, the resist claws are first brought into engagement with the platen and then the pressure rollers are moved away from the platen. By the aforesaid actuation of the operation lever, a lever having at its forward end paper ball rollers adapted to be brought into and out of engagement with the platen is moved through a cam in a manner to release the paper bail rollers from engagement with the platen. The aforesaid actuation of the operation lever is sensed by a switch which generates a signal for effecting control such that a carriage carrying a print head and a guide for guiding a sheet to conform to the outer peripheral surface of the platen is moved to a position suitable for guiding the sheet.
