    Abstract: To prevent an output decrease of laser light due to impurities that could be formed in a guide-light emitting device or an imaging device. A laser-light guiding section includes a transmission window section, an optical component disposed to cause an optical path of the UV laser light emitted from the laser-light output section and an optical path of transmitted light transmitted through the transmission window section to cross, and a sealing member in which the transmission window section is provided, the sealing member configuring a sealed space for airtightly housing the optical component. At least one of a guide-light emitting device configured to emit guide light for visualizing a scanning position of the UV laser light toward the transmission window section and an imaging device configured to receive light for imaging a workpiece via the transmission window section is disposed on the outer side of the sealed space.

    Abstract: An object is to prevent the occurrence of contact failure between a cartridge equipped with a recording medium and an ink jet recording apparatus. A bottle body is crushed to reduce the volume thereof when an ink or solvent is sucked out of the bottle body. A bottle has a neck and a mouth. The neck is rigid. The ROM unit records therein an ink or solvent type, a serial number, the capacity of the bottle, and the amount of remaining ink or solvent. The ROM unit has first and second arms, and freely movably attached to the neck by the first and second arms. A positioning hole is formed on a ROM holder body which houses therein a recording medium. The positioning hole positions the ROM holder body in cooperation with a positioning pin of a reservoir.

    Abstract: Occurrence of a drawing failure is suppressed. An ink jet printer includes: a nozzle configured to eject ink toward a drawing target object; a storage unit that stores drawing data specifying an ejection timing of the nozzle at each of a plurality of offset positions in a conveyance direction, the ejection timing corresponding to drawing information; an optical movement measurement sensor that receives light from the drawing target object and generates a measurement value related to movement of the drawing target object in the conveyance direction based on the received light; and a drawing control unit that controls ink ejection from the nozzle based on reference position information indicating that a reference position of the drawing target object is at a predetermined position, a current offset position with respect to the reference position based on the measurement value generated by the optical movement measurement sensor, and the drawing data.

    Abstract: A ROM unit mounted to a bottle has a plurality of terminal plates on the front end surface of the ROM unit. The ROM unit is movable in a direction orthogonal to a bottle axis Ax, and can be positioned at a retreat position where an interference with a contamination preventing eaves is avoided, and a contact position projected more front than the retreat position. The terminal plates can be electrically contacted with reservoir terminals when positioning at the contact position.

    Abstract: An ink jet printer includes: a nozzle configured to eject the ink toward a drawing target object; a storage unit that stores drawing data specifying an ejection timing of the nozzle at each of a plurality of offset positions in a conveyance direction, the ejection timing corresponding to drawing information; a distance sensor that measures a distance to the drawing target object in an ejection direction of the nozzle; and a drawing control unit that controls ink ejection from the nozzle based on the drawing data and a current relative position from the nozzle to each of a plurality of offset positions of the drawing data. The drawing control unit controls the ink ejection based on a determination result as to whether the distance to the drawing target object in the ejection direction of the nozzle measured by the distance sensor satisfies the predetermined criterion.
