  • Patent number: 8356894
    Abstract: An ink jet recording apparatus includes a recording head which discharges ultraviolet curing inks toward a recording sheet while reciprocally moving in a reciprocal movement direction M crossing a transportation direction S of the recording sheet; and an ultraviolet irradiation head which irradiates ultraviolet rays toward the ultraviolet curing inks discharged from the recording head and attached to the recorded medium. The recording head includes a going recording head and a returning recording head which are disposed at the front and the back of the reciprocal movement direction M with respect to a region in which the ultraviolet irradiation head irradiates the ultraviolet rays to the recording sheet.

  • Patent number: 8061804
    Abstract: A method of moving a cap apart from a printhead within a short period of time without damaging a printing apparatus when the cap sticks to the printhead. A cap moving unit is driven to try to move the cap apart from the printhead. When a detection unit for detecting that the cap has moved apart from the printhead detects that the cap has not moved apart from the printhead, it is controlled to slightly reciprocate the carriage while driving the cap moving unit. When the detection unit detects that the cap has moved apart from the printhead under this control, the slight reciprocation of the carriage is forcibly stopped.

  • Patent number: 7584951
    Abstract: A conveying device which can determine whether an error occurred therein. When a transmission unit is in a transmission state, a sheet feed roller is driven by a DC motor to perform first driving for conveying a sheet up to a conveying roller. The occurrence of an error with respect to the sheet feed roller is determined based on information obtained from an encoder during the first driving. When the occurrence of an error is determined, second driving is performed. A conveyance error is determined based on a count value during the first driving and a count value during the second driving, which are both obtained from the encoder.

  • Patent number: 7344224
    Abstract: A carriage, on which a recording head is mounted, and to which a moving unit is connected, reciprocates a recording area by the moving unit to perform recording by the recording head. In the carriage, a recording head mount part and a connection part to the moving unit are separately provided, and the mount part and the connection part are coupled by a coupling structure having a linear elastic member. Hereby, vibration from the moving unit is shielded in the division portion and is not transmitted to the recording head mount part. Therefore, recording accuracy of the recording head can be kept in a high state.

  • Patent number: 7208235
    Abstract: The present invention provides a method for forming a transparent thin film by a chemical vapor deposition method using a gaseous raw material. In the method, a film growth rate is at least 8 nm/s, and the transparent thin film contains at least one selected from carbon (C) and oxygen (O), nitrogen (N), hydrogen (H), and silicon (Si). According to this method, a transparent thin film that does not peel off a substrate easily due to the eased tension in the thin film and has high transmittance in the visible light region can be deposited on a glass ribbon in a float bath.
