  • Publication number: 20070224874
    Abstract: A connector includes: a housing; and a plurality of metal contacts supported so as to be parallel to each other with respect to the housing, each contact having a first contact arm and a second contact arm, and electrically connecting a first member and a second member to each other by bringing a first contact terminal of the first contact arm and a second contact terminal of the second contact arm into elastic contact with a conductive connection portion of the first member and a conductive connection portion of the second member respectively, the first member and the second member being disposed on both sides of the housing, wherein the housing has a through hole penetrating therethrough and formed on a side of the first contact terminal with respect to a first separation start position at which the first contact arm starts separation from the housing, and a second separation start position at which the second contact arm starts separation from the housing is disposed farther apart from the through hole tha

  • Patent number: 7111934
    Abstract: The feeding apparatus 50 includes a hopper 51 that is provided operable to support the papers in inclined attitude and pivot around a pivot axis 51a, and a feed roller 53 that is provided at a feed roller shaft 54 and feeds the paper to the downstream side by rotating in contact with the paper. When seen from the side view of the feeding path, guide rollers 57 and 58 are provided near the feed roller 53 and are driven to rotate in contact with paper. A movable member, provided near the feed roller 53, pivots around a pivot axis 63a so that the movable member moves backward and forward to the feeding path. Accordingly, a clearance between the feed roller 53 and the hopper 51 is narrowed.

  • Publication number: 20060193670
    Abstract: A gap detector is operable to detect a distance between a liquid electing head adapted to eject liquid toward a target medium and a platen adapted to support the target medium. A circular plate is adapted to be provided on a guide shaft which is rotated together with the rotary plate to selectively determine the distance as one of a plurality of distances. The circular plate has a plurality of flags formed on an outer periphery, each of which is associated with one of the distances. A sensor is disposed in the vicinity of the outer periphery of the circular plate and operable to output a signal indicative of a passage of each of the flags in accordance with the rotation of the circular plate. At least one of intervals between the flags in a circumferential direction of the circular plate is made different from the other.
