摘要： An ink jet printer includes a rotary drum having a peripheral surface for holding a paper sheet, a print head for printing an image on the paper sheet held on the peripheral surface by jetting ink to the paper sheet, and an elevator mechanism for setting the print head to a printing position close to the peripheral surfice at a time of printing and to a non-printing position farther from the peripheral surface than the printing position along a normal line of the peripheral surface at a time of maintenance. Particularly, the elevator mechanism includes a pair of guide rails set parallel to the normal line of the peripheral surface, a slider unit rotatably holding the print head and slidably attached to the guide rails, and a driving section for moving the slider unit up and down. The slider unit includes a spindle, a head support member rotatable about the spindle by a rotational force applied due to a weight of the printhead, and a posture regulator for regulating a posture of the print head with respect to the guide rails against the rotational force.

摘要： An ink-jet printer with an ink nozzle purging device includes a valve equipped in a portion of an ink supply pipe extending from a pump to a printing head unit, and an ink urging unit which has a chamber equipped in a portion of the pipe between the valve and the pump, and further has an elastic member disposed in the chamber. The member accumulates an elastic force by a pressure of the ink entering into the chamber while the pump is operated with the valve being closed, and then urges the ink toward the printing head unit when the valve is opened to release the elastic force accumulated in the elastic member.

摘要： An apparatus for securing a typewriter, includes a locking device for locking an outer case in a closed position and a fastening device for fastening a bottom plate of the case to a mounting base. When opened, the cover permits a portion of the bottom plate to be exposed. The fastening device is brought, from inside the case, into engagement with the bottom plate of the case through the exposed portion of the bottom plate, thereby locking the typewriter to the mounting base. The fastening device for the bottom plate cannot be released unless the locking device is unlocked by a key to open the cover. Accordingly, only a keyholder can unlock the locking device, thus preventing the typewriter from being stolen. Further, since the fastening device is engaged with the bottom plate of the typewriter case, the outer appearance of the typewriter is not degraded.
