A sheet slicing mechanism includes a rigid frame member supporting a stepper motor coupled to a drive gear. A rotatably supportable rotary member includes a driven gear coupled to the drive gear and is rotatably supported upon the frame. A blade frame having a generally cylindrical configuration is received within the rotary member and is freely movable in the vertical axis. The blade frame supports a cutting blade and a cutting force weight. The rotary member defines a vertical slot which cooperates with an outwardly extending pin in the blade frame to permit the blade frame to be vertically movable with respect to the rotary member while locked thereto as to rotational motion. A solenoid activated lifting means is supported upon the frame and is operable to raise the blade frame to a noncutting position.
