り機構。 A paper feed roller that takes out predetermined sheets of paper one by one is arranged inside the printer body so that it can be rotated freely by a paper feed drive motor, and a paper feed roller that transports the paper conveyed by this paper feed roller to a predetermined printing position. In the paper feed mechanism of a printer, the paper feed mechanism is provided with a pressure roller that is in pressure contact with the paper feed roller, and a paper ejection roller that ejects the paper after printing. A clutch mechanism is connected that rotates the paper roller only in a predetermined paper feeding direction, and the pressure roller is brought into pressure contact with the paper feed roller by the rotation of the paper feed drive motor in the paper feed direction, and the pressure roller is pressed against the paper feed roller by rotation of the paper feed drive motor in the paper feed direction. 1. A paper feed mechanism for a printer, comprising a roller contact/separation mechanism that separates the paper from the paper feed roller by rotation in a direction.
