  • Patent number: 8967617
    Abstract: The present invention is to provide a printing apparatus capable of correctly detecting an origin of a conveying roller for conveying a print medium at the time of its rotation with a simple configuration that does not accompany an increase of cost. For this purpose, the printing apparatus is equipped with a lock mechanism (a lock link lever) for stopping rotation of the conveying roller at a predetermined rotational position and saves a count value of a rotation amount of the conveying roller when the conveying roller is locked by the lock mechanism concerned as origin information. After this, driving of the conveying roller is controlled based on the saved origin information and a phase of rotation of the conveying roller obtained from the count value of the conveying roller.

  • Patent number: 8684046
    Abstract: A puncture repair kit has a bottle unit positioned with greater stability. A puncture repair kit includes a compressor device, and a bottle unit in which a cap is attached to an opening in a bottle container which houses a puncture sealing agent. The compressor device includes a compressed air discharge port. The cap includes an air intake port for feeding compressed air from the compressed air discharge port into the bottle container, and a sealing agent/compressed air removal port for removing puncture sealing agent and compressed air in succession from the bottle container by feeding in compressed air. When the cap of the bottle unit is oriented downwards, the air intake port is directly connected with the compressed air discharge port.

  • Patent number: 8678370
    Abstract: A recording apparatus to record an image on a recording medium using a recording head includes a first conveying roller, a second conveying roller, and a controller. The first conveying roller is positioned upstream of the recording head in a conveying direction and the second conveying roller is positioned downstream of the recording head in the conveying direction. In response to a first conveying mode being selected, the controller performs a rotational phase control in which the controller controls rotational phases of the first conveying roller and the second conveying roller such that the recording medium is conveyed by predetermined sections of circumferences of the first conveying roller and the second conveying roller when a trailing end of the recording medium passes the first conveying roller. In response to the second conveying mode being selected, the controller does not perform the rotational phase control.

  • Publication number: 20140078207
    Abstract: A printing apparatus includes a printing unit, a first and second conveying units conveying a printing medium, a driving unit driving the conveying units and a control unit controlling the driving unit. A load mutually acting on the conveying units through the medium in a conveyance state by the conveying units is recursively calculated for each predetermined conveyance unit while setting the initial value to 0. The driving unit is controlled based on the calculation result at the time of the transition to suppress a fluctuation in a conveyance amount at the time of the transition of the conveyance state of the medium from the conveyance state by the conveying units to a conveyance state only by the second conveying unit.

  • Publication number: 20140078206
    Abstract: A printing apparatus includes a printing unit, first and second conveying units conveying a printing medium, a driving unit driving the first and second conveying units, and a control unit controlling the driving unit. The conveyance state of the printing medium makes transition from a first conveyance state in which the printing medium is conveyed only by the first conveying unit to a second conveyance state in which the printing medium is conveyed by both the first and second conveying units. The control unit controls the driving unit based on a fluctuation in a load that mutually acts between the first and second conveying units through the printing medium to suppress a fluctuation in a conveyance amount at the time of the transition of the conveyance state from the first conveyance state to the second conveyance state.
