  • Patent number: 9796546
    Abstract: A vacuum belt moves between a print head and a manifold. The manifold has manifold chambers, and each of the manifold chambers has manifold openings. Vacuum lines are connected to the manifold chambers. The vacuum lines exert vacuum force upon the manifold chambers, and the manifold openings exert the vacuum force through belt perforations. A cylindrical valve structure is connected to the vacuum lines. The cylindrical valve structure includes a cylindrical sleeve (having sleeve openings connected to the vacuum lines) and an internal valve cylinder positioned within the cylindrical sleeve. The internal valve cylinder has groups of vacuum slots. The internal valve cylinder moves linearly within the cylindrical sleeve (in directions parallel to cylindrical walls of the cylindrical sleeve) to align only one of the groups of vacuum slots with the sleeve openings at a time, so as to control which of the manifold chambers receive the vacuum draw.

  • Patent number: 9796551
    Abstract: A paper guide mechanism that facilitates operation without easily allowing deviation of a wide guide unit. In a paper guide mechanism (10), a position-holding member (13) holds the widthwise position of a widthwise moving member (12) by bringing a first fixing-side locking section (11e) and a first moving-side locking section (13d) into contact with each other on a surface perpendicular to a direction of movement of the widthwise moving member (12) even in a case in which the widthwise moving member (12) is about to move in any direction along the width direction. The position-holding member (13) has a movement-restricting section (13e).

  • Patent number: 9796544
    Abstract: There is provided a feed apparatus including a support unit, a feed roller, a swingable arm to support the feed roller, a guide unit, a movable member movable to a retracted position and a protruding position at which the movable member can abut against the sheet supported by the support unit, a driving source, driving transmission units; and a contact-separating mechanism to move the feed roller to a separated position and an abutment position at which the feed roller abuts against the sheet supported by the support unit. In a state in which the movable member is the protruding position and the feed roller is the separated position, a time required to start feeding of the sheet by the feed roller moved from the separated position to the abutment position is longer than a time required to shift the movable member from the protruding position to the retracted position.

  • Patent number: 9784660
    Abstract: Provided are a microparticle sorting device, and a method and a program for sorting microparticles capable of stabilizing sorting performance over a prolonged period of time. The microparticle sorting device includes an imaging element and a controller. The imaging element obtains an image of fluid and fluid droplets at a position where the fluid discharged from an orifice which generates a fluid stream is converted into the fluid droplets. The controller controls driving voltage of an oscillation element which gives oscillation to the orifice and/or controls a position of the imaging element based on a state of the fluid in the image and/or a state of a satellite fluid droplet. The satellite fluid droplet does not include microparticles and exists between the position, where the fluid is converted into the fluid droplets, and a fluid droplet, among fluid droplets including the microparticles, which is closest to the position where the fluid is converted into the fluid droplets.

  • Patent number: 9758328
    Abstract: A transport mechanism for a peripheral device and an operating method including the same are provided. The transport mechanism includes a tray, at least a transport roller, a detector, a trigger component and a processor. The tray includes an opening extending through the tray. The transport roller is rotatably installed in the opening and protruded from the tray to transport a flexible object to move along a transport path. The detector near the tray has a detecting area. The trigger component is located in the opening and spaced apart from the flexible object on the transport path. The flexible object deviated from the transport path presses the trigger component to enter or leave the detecting area and triggers the detector to transmit an abnormal detecting signal. The processor receives the abnormal detecting signal to stop the transport roller.

  • Patent number: 9758325
    Abstract: Provided is an image forming apparatus that, even when a paper feeding cassette is open, positively performs paper feeding from a manual feed tray, and yet shortens the printing interrupt time. Image forming apparatus includes a paper feeding cassette, guide member, paper feeding changeover determining part, and system control part. Paper feeding cassette is detachably loaded in an apparatus main body. Guide member is temporarily fixed in apparatus main body above paper feeding cassette, constituting a carrying passage for a paper sheet from manual feed tray. If paper feeding cassette is drawn out from apparatus main body, paper feeding changeover determining part determines whether or not paper feeding can be changed over to that from manual feed tray. If the result of determination by paper feeding changeover determining part shows that changeover is possible, system control part causes paper feeding from manual feed tray to be performed.
