  • Patent number: 5009532
    Abstract: A paper feeding apparatus associated with a printer for storing a plurality of individual recording media and for controlling the release of individual recording media from a storage device toward a platen of the printer. A transmission mechanism couples rotation of the platen in a counterclockwise direction which rotates the paper feeding rollers in a clockwise direction for releasing the individual recording media from the storage device. Rotation of the platen in a clockwise direction halts rotation of the paper feeding rollers preventing further release of individual recording media from the storage device while rotating auxiliary paper feeding rollers in a counterclockwise direction for advancing the individual recording medium toward the platen. A release lever disengages the paper feeding rollers and auxiliary paper feeding mechanism to permit use of continuous print media.

  • Patent number: 4602882
    Abstract: A serial printer includes a control circuit for driving the printer carriage. The control circuit detects the change of level of a home position signal in synchronism with a print position signal which is produced based upon occurrence of particular data selected out of a cycle of data for driving a step motor so as to increase the permissible range of variation in the change of the level of the home position signal that takes place due to mechanical vibrations differing in mode or phase.

  • Patent number: 4525085
    Abstract: The print head of a serial printer includes a protruding plug which is seated and locked into a receptacle on a translating carriage. An endless belt has teeth engaged in a correspondingly contoured groove of the carriage for positive connection between carriage and belt, whereby the head traverses the printing medium for printing thereon. The platen is positively and simply held and includes a resin surface for impact of print wires. The gap between the head and platen is readily adjusted in steps by motion of a lever.

  • Patent number: 4500023
    Abstract: A paper feeding apparatus for use in a printer is capable of feeding both continuous computer or fan-fold paper having holes in the peripheral edges thereof and single sheets of paper such as letter paper. The paper feeding apparatus includes a frame having a platen rotatably supported thereon and a guide shaft supported on the frame. First and second paper feeding members are disposed on the guide shaft and spaced apart for feeding a fan-fold paper along the peripheral edges thereof by means of the holes therealong. First and second guide members are disposed intermediate the first and second paper feeding members. The first and second paper guide members each have a first portion for guiding a continuous fan-fold paper fed by the first and second paper feeding members, a second portion for guiding a single sheet of paper while being inserted and fed into the printer and a third surface for guiding a single sheet of paper while it is being fed out of the printer, past the platen.

  • Patent number: 4492484
    Abstract: A printing device for use in a wire dot printer having a plurality of printing wires. The printing device includes a frame and a carriage slidably supported on the frame for lateral translation thereacross. A printing head is supported on the carriage and includes a nose member which supports the plurality of printing wires. First and second holding members are disposed on the carriage so that the nose member is intermediate the first and second holding members. A ribbon mask constructed from an elastic material is disposed on the nose member. The ribbon mask is removably held between the first and second holding members and extends across the nose member.

  • Patent number: 4196667
    Abstract: A print hammer having an improved head portion for striking a selected moving print character member in a line printing device is provided. The printing device prints when the print hammer strikes a print character member at a predetermined print position forcing the character member against an ink ribbon, a print paper and a platen. The head portion is formed with an inclined surface facing the direction of approaching adjacent character members to drive an adjacent character member striking the side of the print hammer around the print hammer for avoiding jamming and damage to character members and print hammers. In a preferred embodiment the head portion is substantially "V" shaped with the apex of the V disposed in a direction opposite to the movement of the print character members.

  • Patent number: 4173183
    Abstract: In a line printer character belt in which characters are mounted on flexible fingers which are struck by printing hammers toward a platen in the printing operation, the fingers are flexed toward the platen by a projection on the fingers or on a character block on which the fingers are mounted. Vibration subsequent to the printing operation is eliminated, thereby providing excellent printing quality free of dirt and ghosts.
