    Abstract: The ink-jet printer head includes a cavity unit which has a plurality of pressure chambers arranged in a plurality of pressure-chamber rows; an actuator unit which has individual surface electrodes corresponding to the pressure chambers respectively, and land portions conducted to the individual surface electrodes respectively; and a flexible cable which has connection terminals and signal lines. The land portions and the connection terminals are electrically connected. In each of the pressure-chamber rows, the land portions are arranged such that a certain land portion is shifted from another land portion adjacent to the certain land portion in a longitudinal direction of the pressure chambers. Accordingly, even when the pressure chambers are arranged highly densely, it is possible to electrically connect the flexible cable and the actuator unit easily.

    Abstract: An image forming apparatus including an image forming portion that forms an image on a surface of a sheet, a feeding device that feeds the sheet in a sheet feeding direction, a sheet receiving portion, and an engagement portion selectively moves between a first position and a second position. When the engagement portion is in the first position, the engagement portion engages the leading end of the sheet. When the engagement portion is in the second position, the engagement portion does not engage the sheet. When the engagement portion is in the first position, the engagement portion engages a leading end of the sheet before a trailing end of the sheet passes the feeding device. The sheet receiving portion receives the sheet after the engagement portion engages the leading end of the sheet.

  • Publication number: 20090244139
    Abstract: An object of the invention is to provide a liquid droplet ejecting apparatus capable of determining a type of droplet to be ejected through each nozzle at an arbitrary ejection timing, with consideration of not only an influence of droplet ejections at preceding and following ejection timings, but also crosstalk between a nozzle column and another nozzle column. A data generation circuit of the liquid droplet ejecting apparatus includes a first storage unit, a second storage unit, and a droplet type determination unit. The first storage unit stores therein information on a plurality of types of droplets. The second storage unit stores therein time-sequence information of a type of droplet which information associates each ejection timing of each nozzle with one of the types of droplets.

  • Patent number: 7448613
    Abstract: A lifting plate provided in a sheet accommodating member is locked at a position, to which the lifting plate is downwardly turned against a pushing force of a spring, by a locking mechanism having a locking member configured to lock the lifting plate, and also having a lock releasing lever configured to release locking of the lifting plate by the locking member. When the sheet accommodating unit is mounted, the lock releasing lever is made to abut against a lock release member. Thus, the lock releasing lever is moved integrally with the locking member in a lock release direction. When the sheet accommodating unit is drawn out, the lock releasing lever is made to abut against the lock release member. Thus, the lock releasing lever is singly moved in a direction opposite to the lock release direction to maintain the locking of the lifting plate by the locking member.
