Abstract
In an ink jet type print recording apparatus, a predetermined number of pulses are first produced in a positive direction when gear disengagement is carried out to drive an line feed motor in a forward direction at an angular amplitude within a half of a gear tooth width. Subsequently, pulses whose number is twice as large as the predetermined number are produced in the opposite direction to drive the line feed motor in the reverse direction. Subsequently, a predetermined number of pulses are produced in the positive direction again to drive the line feed motor in the forward direction. With this operation, an idle gear is smoothly disengaged from a link target gear. The line feed motor is reciprocatively driven in the same manner as described above when the idle gear is linked to a new link target gear.

6540320 - Low-height ink jet service station - Owned by Hewlett-Packard Company (Palo Alto, CA)

A system and a method for servicing a printhead using a low-height service station design. The system of the present invention includes a low-height service station having a gear and clutch arrangement that permits a service station drive assembly and a print media feed assembly to use the same motor. By momentarily reversing the motor, the gear and clutch arrangement permits the service station drive assembly to be engaged and the print media feed assembly to be disengaged, or vice versa. Moreover, the gear and clutch arrangement provides a means for a capping platform and a wiping platform within the service station to move independently of each other.

7293869 - Recording medium processing apparatus - Owned by Toshiba Tec Kabushiki Kaisha (Tokyo,JP)

The apparatus has a carriage that holds a head, a carriage-driving mechanism having a motor, and a holding mechanism configured to press a recording medium to a medium-holding base. The holding mechanism has a pair of arm members and a pushing member secured to the arm members. A spring urges the holding mechanism toward the medium-holding base. The carriage can move to a first region and farther to as second region. In the first region, the head can read data from the recording medium. The apparatus has a sliding member that moves together with the carriage while the carriage remains in the second region. When the carriage moves to the second region and moves together with the carriage, the pushing member moves away from the medium-holding base.

6173551 - Ink jet coder system and method - Owned by Philip Morris Incorporated (New York, NY)

A cigarette packing apparatus comprising means for repetitively progressing labels through a print location, a signal generator configured to generate a signal indicative of presence of the label as it passes adjacent the print location, a second signal generator configured to generate a signal indicative of a speed at the print location; a fluid jet printer head adjacent the print location and a controller configured to operate the printer head responsively to the first and second signal generators, with an additional arrangement within the packing apparatus defining a contact-free path portion sufficient for ink to dry at the indicia-bearing portion of the label as the label is progressed beyond the print location.

6890055 - Power transmission arrangement - Owned by Hewlett-Packard Development Company, L.P. (Houston, TX)

A power transmission arrangement includes a shaft, a first gear mounted on the shaft, a plate supported by the shaft and rotatable between a first position and a second position, a second gear supported by the plate and engaged with the first gear, and a third gear supported by the plate and movable between a disengaged position and an engaged position with the second gear when the plate is rotated between the first position and the second position.

7464922 - Image-recording apparatus, and recording-medium supply device - Owned by Brother Kogyo Kabushiki Kaisha (JP)

An image-recording apparatus including (a) a carriage carrying a recording head, (b) a maintenance unit disposed at a standby position located outside a recording area (L) of the recording head, (c) medium feeding devices to feed recording media from respective cassettes (d) first, second and third gears which are disposed outside the recording area and through which a drive force is selectively transmitted from a drive-force output gear to one of the medium feeding devices and the maintenance device, and (e) a power-transmission switching device having a shift gear which is moved for selective meshing engagement with the first, second and third gears according to a distance of movement of the carriage from the recording area toward the maintenance unit. In at least one of the medium feeding devices, a support arm pivotally supported at its proximal end portion by a drive shaft and rotatably supporting a rotary medium-supply member at its free end portion is biased by a biasing device pivotally about the axis of rotation of the drive shaft in a direction for moving the free end portion toward the stack of recording media, and in an axial direction of the drive shaft against a support frame which rotatably supports the drive shaft.
