20080259116 | RECORDING APPARATUS - There is provided a recording apparatus including a recording head which includes a nozzle plate having conductive property including an opening and for ejecting ink toward a medium to be recorded from the opening, an absorbing member disposed so as to oppose the nozzle plate in the ejecting direction of the ink from the recording head and for absorbing the ink not adhered to the medium to be recorded, an electrode disposed so as to make contact with the absorbing member, and an electric potential difference generator for generating an electric potential difference between the nozzle plate and the electrode and electrically attracting the ink not adhered to the medium to be recorded toward the electrode side. The electric potential difference generator generates an electric potential difference so that the magnitude of the electric potential difference is varied in accordance with a distance between a portion of the absorbing member to which the ink is absorbed and the nozzle plate. | 10-23-2008 |
20090115827 | RECORDING APPARATUS AND LIQUID EJECTING APPARATUS - 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. | 05-07-2009 |
20090115828 | RECORDING APPARATUS AND LIQUID EJECTING APPARATUS - The present invention relates to an ink jet recording apparatus having an ultraviolet irradiation head having a discharge tube. Solving means include a recording head that reciprocates along the surface of recording paper and discharges ultraviolet curable ink toward the recording paper, a discharge tube that moves together with the recording head and outputs ultraviolet light, and a movable plane reflecting mirror that switches between two light paths through which ultraviolet light from the discharge tube is applied in front of and behind the recording head in the reciprocation direction M. The discharge tube may include an elliptic reflecting mirror that converges output ultraviolet light toward the surface of the recording paper. | 05-07-2009 |

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. | 05-09-2013 |
20140152734 | PRINTING APPARATUS - A printing apparatus includes a position detection unit which includes an optical element, a light source and a light receiving element, radiates light from the light source toward the printing surface, causes diffused reflection light of reflection light which is reflected by the printing surface to be incident to the light receiving element through the optical element and outputs positional information relating to a position of the printing surface at which the light from the light source reflects, from the light receiving element, and a controller which causes movement of the carriage to stop when lifting up of the printing medium is detected on a basis of the positional information output from the light receiving element, in which a virtual plane which contains the optical element and the light receiving element is in a state of being inclined in relation to a normal line of the printing surface. | 06-05-2014 |
20140192109 | PRINTING APPARATUS - A printing apparatus includes a print head that forms an image on a target printing surface of a printing medium by relatively moving with respect to the printing medium, an elastic wave radiation unit that radiates elastic waves, in air toward the target printing surface, a reception unit that receives the elastic waves that are radiated from the elastic wave radiation unit and reflected by the target printing surface, and a control unit which measures the time of arrival taken for elastic waves, and stops relative movement when the time of arrival is shorter than a defined time, in which the defined time is a time of arrival in which a distance from the print head to the printing medium and the distance from the elastic wave radiation unit to the printing medium to an allowable minimum distance between the print head and the printing medium. | 07-10-2014 |
20140192361 | RECORDING MEDIUM DETERMINING DEVICE AND RECORDING MEDIUM DETERMINATION METHOD - A recording medium determining device includes a light irradiating portion that irradiates a recording medium with visible light; a regular reflection light receiving portion that receives regular reflection light regularly reflected by the recording medium irradiated with light from the light irradiating portion; a diffused reflection light receiving portion that receives diffused reflection light diffusely reflected by the recording medium irradiated with light from the light irradiating portion; and a determining portion that determines the type of recording medium on the basis of each light amount of two or more visible light components with different wavelengths to one another among the light components received by the regular reflection light receiving portion and each light amount of two or more visible light components with different wavelengths to one another among the light components received by the diffused reflection light receiving portion. | 07-10-2014 |
20140192368 | RECORDING MEDIUM DETERMINATION APPARATUS AND RECORDING MEDIUM DETERMINATION METHOD - A recording medium determination apparatus includes a light radiation unit which radiates light toward a recording medium; a light receiving unit which receives diffuse reflection light, which is light radiated from the light radiation unit and diffuse reflected by the recording medium; a reflection portion which can reflect transmitted light, which is radiated from the light radiation unit and transmitted through the recording medium, to cause the transmitted light to be incident to the recording medium again; a switching unit which switches a reflectance state such that a reflectance of the reflection portion changes; and a determination unit which determines a thickness of the recording medium on a basis of a value of a ratio between light amounts of a plurality of the diffuse reflection lights which are reflected by the reflection portion in different reflectance states and are received by the light receiving unit. | 07-10-2014 |
20140293336 | PRINT SYSTEM AND INFORMATION PROCESSING DEVICE - A print system includes: a cartridge information reading unit that reads out cartridge information including tape color information about a color of a print surface of tape-like member housed in a cartridge installed in a tape printing device and ink color information about a color of an ink ribbon housed in the cartridge, from a cartridge information recording unit provided in the cartridge; a cartridge information acquisition unit that acquires the read-out cartridge information; and a display unit that shows a color display of the color of the print surface of the tape-like member and the color of the ink ribbon, based on the tape color information and the ink color information included in the acquired cartridge information. | 10-02-2014 |
