Abstract: A printer includes a stationary paper chute extending along the outer peripheral surface of a platen over a limited angular extent thereof so as to define therebetween a paper feed passage, the paper chute having an opening through which a pinch roller is movable into and out of the paper feed passage for releasably locking a paper on the platen. The printer further has a pinch roller actuating mechanism which includes a pressure spring disposed adjacent to the paper chute for biasing the pinch roller against the platen, the pressure spring being composed of a cantilevered resilient strip having a free end on which the pinch roller is rotatably supported, and a release camshaft rotatably disposed between the paper chute and the pressure spring and angularly movable to resiliently displace the pressure spring in a direction to move the pinch roller away from the platen.

Abstract: This theater ticket issuing machine uses a single print head to print on any selected one of three differently-colored ticket stocks. Guides establish three separate ticket stock paths, one for each color of ticket stock. These three paths converge into a common path where printing takes place. Each path has its own feed rollers driven by reversible stepping motors under microprocessor control. A cutter is located beyond the print head in the normal direction of ticket stock movement. After cutting, ticket stock is withdrawn by reverse operation of the appropriate feed rollers to clear the common path, at least where a different ticket stock is to be fed in the next issuing operation. The microprocessor can be made to eliminate the clearing step when the color of the next ticket to issue is the same as that of the last ticket issued.

Abstract: There is disclosed an improvement upon a cancellation type printing mechanism or a stored energy type printing mechanism having magnetic members, so-called armatures, attracted by a permanent magnet while resiliently deflecting resilient members connected to one end thereof. The magnetic members are associated with corresponding electro-magnets which are adapted to be energized selectively to release the associated magnetic members by cancelling the magnetic attracting force of the permanent magnet, so that the magnetic member is actuated by the energy stored in the corresponding resilient members thereby to drive the printing elements. One end of the magnetic member contacts the magnetic pole surface of the permanent magnet or a yoke mounted on the permanent magnet so as to form a fulcrum for the rotation of the magnetic member. A recess is formed on one side of the magnetic member facing a core of the electro-magnet, so that the magnetic member does not engage the corner of the core of the electro-magnet.

Abstract: A printing plate is directly mounted on a plate cylinder by first placing small holes in the non-image area of the printing plate on register holes in the plate cylinder and by then inserting register pins through the small holes and into the register holes so that the two holes are brought into complete registry with each other. Remounting a removed printing plate at the same position on the cylinder at which it was mounted before may be readily performed by relying on X-Y coordinates of the previous position for finding the corresponding register holes and then by reperforming the method as described above. This will result in a considerable reduction in the manpower required for the plate mounting operation and in the subsequent work to bring the plate into accurate registry with the cylinder.

Abstract: A small-sized printer has a carriage moving in front of a platen. A print wheel is rotatably mounted on the carriage and coupled to a print wheel gear. The print wheel gear meshes with two worm gears which extend parallel to the platen. A rack-like cam also lies parallel to the platen and is followed by rocking lever which drives a pivoted hammer support. A pivoted hammer on the pivoted support strikes the inside of the print wheel, forcing an inked character to print on the paper, and rolling the character on the paper as the carriage moves. The two worm gears are powered by a motor which acts through a print drive. Their rotation is controlled so that the print wheel is rotated for print character selection by rotating both worm gears to turn the print wheel gear, the carriage is caused to move along the print line by stopping rotation of one of the worm gears, and the carriage is caused to return to its original position by stopping the other worm gear.
