Abstract
A printer mechanism includes a single motor turning a system drive gear in a paper feeding direction, and in a cam driving direction, opposite the paper feeding direction. When the system drive gear is turned in the paper feeding direction, a paper feeding spring clutch drives a paper feed roll with the system drive gear. When the system drive gear is turned in the cam driving direction, a drive cam is driven by a cam driving spring clutch. The drive cam has a first surface driving a moving knife blade across a stationary knife blade in a cutting direction, and in a return direction opposite the cutting direction. With this movement in the cutting direction, the moving knife is held against the stationary knife blade, and, with movement in the return direction, the moving knife is moved away from the stationary knife blade, by means of a second surface of the drive cam. Provision is made to allow the cam driving clutch and cam to return to an original configuration after an event in which knowledge is lost of the operating mode and position of the mechanism.
