摘要:
A video printing apparatus and method in which, without interlocking the movement of the printing head with the capstan for carrying the printing paper and the paper feeding mechanism by a cam and linkage mechanism, they are respectively operated by three independent motors. The printer includes a first normally and reversely rotatable DC motor for searching the head of the ink ribbon of the ribbon cassette housed in the printer and for taking up the ink ribbon by the take-up reel base during the printing operation. A second normally and reversely rotatable stepping motor is provided for carrying the printing paper housed in the tray by the capstan and the pinch roller to the printing position and the paper delivering position. A third normally and reversely rotatable DC motor is provided for moving the printing head which subjects the printing paper to the printing processing by pressing the ink ribbon of the ribbon cassette thereon in cooperation with the platen. A control mechanism for locking the tray in position, pressing the printing paper in the tray into engagement with a first feeding roller and moving the pinch roller into engagement with the capstan includes a plurality of cams disposed on a common axis which are driven by the first motor.
