O Utility Model Registration Claims A platen, a pressure roller formed to be able to press against and separate from the platen, and the leading edge of the paper coming into contact with a position slightly after passing through the pressure contact point between the pressure roller and the platen. In the paper feeding device of the printing device, the pressure arm supports the pressure roller and is swingable between a pressure contact position and a release position of the pressure port and roller by a support shaft. and,
a spring that applies a force to the pressure arm toward the pressure contact position; a release member that pushes the pressure arm toward the release position; and a manual lever that moves the release member; The pressure arm IJ has a spring that is rotatably supported by the pressure arm IJ, and has a spring that applies force to press the stopper claw against the platen, and a pressing member that presses the stopper claw in a direction away from the platen.
A paper feed device for a printing device, characterized in that it is drivingly connected to an IJ-space member.

Claims

[Scope of utility model registration request]

A platen, a paper guide member disposed with a gap from the platen and having a curvature corresponding to the platen, a pressure roller penetrating the paper guide member so as to be able to press against and release from the platen; In a paper feeding device of a printing device that has a stopper claw that aligns the leading edge of the paper by abutting the leading edge of the paper at a position slightly after passing the pressure contact point between the pressure roller and the platen, when the platen is stopped. The stopper claw comes into contact with the platen when the pressure roller is disengaged from the platen, and makes it possible to align the leading edge of the paper inserted between the paper guide member and the platen.
．． After aligning the leading edge of the paper, the pressure roller moves from a disengaged state to a pressure contact state with respect to the platen, and the paper is sandwiched between the platen and the pressure roller, and after the paper is sandwiched, the stopper claw is released from the platen and moves. A paper feeding device for a printing device, characterized in that the platen is driven to feed the paper after the stopper claw is released from the lock.
