  • Publication number: 20100329769
    Abstract: A roll paper printer having a cover movable between an open and closed position with the printer having hooks on locking levers disposed to the cover to hold the cover in the locked position upon engaging pins located on the printer body side and having an opening lever to unlock the cover. The printer also includes a paper cutter device having a stationary knife which is attached to the cover and contact plate parts which extend from the stationary knife for contacting the front panel part on the printer body and having extension springs disposed in tension for pulling the stationary knife towards the back of the printer such that upon closing the cover the contact plate parts push the cover to the front of the printer. This causes the hooks of the locking levers to press from the back against the engagement pins to eliminate any play in the cover when in cover is in the locked position and to assist in opening the cover when the cover opening lever is operated.

  • Publication number: 20100283823
    Abstract: A printer for printing a barcode by discharging ink droplets from print nozzles that are used for printing bars in the bar code. The printer includes a CPU and a head carriage mechanism. The CPU divides a length of the bars of the barcode into a plurality of segments and changes which of the nozzles that are used as print nozzles in each segment such that the barcode is printed by discharging ink droplets from the print nozzles in each segment. The head carriage mechanism is for moving the print medium relative to the print nozzles. Each bar of the resulting barcode extends in a single, diagonal direction across the plurality of segments. Other printers and printing methods are also provided.

  • Patent number: 7780287
    Abstract: A printing method for printing a barcode forms a plurality of dots on a print medium from one end of the bars to the other end by discharging ink droplets from print nozzles assigned to print the bars from among a plurality of nozzles aligned in a direction intersecting the bars. The printing method divides the barcode in the direction of the length of the bars into a plurality of segments, changes which of the plural nozzles are assigned as print nozzles in each of the segments, and discharges ink from the print nozzles in each of the segments to print the barcode.

  • Publication number: 20080278023
    Abstract: Winding is wound around each of a plurality of core arm portions formed integrally with a core cylinder portion of a stator core. Windings wound around the respective core arm portions are 3-phase-configured such that one end of winding of each phase extends outwardly as an output wire, three output wires in total, and such that the other end of winding of each phase is connected at a common node, thereby establishing Y-connection. Two of the three output wires are fixedly pressed by crossover wires extending between windings wound around the respective core arm portions, whereas the remaining one output wire is fixedly pressed by a winding end wire of winding of an adjacent phase.
