  • Publication number: 20240059061
    Abstract: Provided is an inkjet printer capable of suppressing variations in landing positions of inks ejected from a plurality of inkjet heads mounted on a carriage for each inkjet head. In this inkjet printer, a plurality of inkjet heads 3 are mounted on a carriage. This inkjet printer includes at least one of a first inclination adjustment mechanism (13) for adjusting the inclination of each of the inkjet heads (3) with respect to the carriage in a pivoting direction having a sub scanning direction as an axial direction of pivoting, and a second inclination adjustment mechanism (14) for adjusting the inclination of each of the inkjet heads (3) with respect to the carriage in a pivoting direction having a main scanning direction as an axial direction of pivoting.

  • Patent number: 10124578
    Abstract: A nozzle-clogging determining device is provided for detecting nozzle clogging without causing an increase in the cost. A nozzle-clogging determining device is configured to detect pass of droplets ejected from a plurality of nozzles of a head of an inkjet printer, and includes a droplet detector and a determination controller. The droplet detector includes a light emitter configured to emit detection light for detecting pass of droplets in a direction intersecting with a traveling direction of droplets, and a light receiver configured to receive the detection light. The determination controller consecutively ejects a plurality of droplets from each nozzle of the head at equal intervals, and has a threshold for performing determination on nozzle clogging on the basis of a light interception rate of the detection light which the light receiver receives when droplets are positioned inside a spot of the detection light which the light receiver receives.

  • Patent number: 9956770
    Abstract: A droplet detection device includes a light emitting element that emits a detection light for detecting shielding of at least one part by a microdroplet discharged from a nozzle of a head of an ink jet printer in a direction intersecting an advancing direction of the microdroplet; a light receiving element; and a pair of wall portions facing each other and enabling the microdoplet to pass therebetween; where the wall portions have one part of a light path of the detection light from the light emitting element to the light receiving element and allows at least one part of the detection light to be reflected and to reach the light receiving element, and the detection light has a width in a direction equal to a spacing in the direction of the wall portions in a region sandwiched by ends on the light emitting element side of the wall portions.

  • Patent number: 9751322
    Abstract: A waste ink recovery device (1) which is a fluid transport device has a tubing pump (40) configured to rotate around a shaft center by a motor, thereby transporting waste ink into a recovery container, flow passage members (30) for guiding the waste ink into the tubing pump (40), a flow passage selector (50), and a one-way clutch (70). The flow passage selector (50) has operating members (53) for opening and closing internal flow passages of the flow passage members (30), and an eccentric cam (54) configured to make the operating members (53) open and close the internal flow passages of the flow passage members (30).

  • Patent number: 9610776
    Abstract: A connection member is provided that can be fabricated at low cost and easily attached to a target component. The connection member is a member to be connected to and to communicate with a first component. The connection member is further connectable to another connection member to be connected to and to communicate with a second component. The connection member includes a communicating portion connectable to and communicatable with the first component, engaging portions engageable into the other connection member, and engaged portions into which the other connection member is engageable. These connection members are mutually connectable to communicate with each other.
