An electronic apparatus has a fixed case unit and a movable case unit, and the rotation operability of the movable case unit is improved. The electronic apparatus having the fixed case unit and movable case unit also includes a movable arm, which is fitted openably and closably to the fixed case unit via a hinge. The movable case unit is supported rotatably on the movable arm, and the rotation center of the movable case unit is set at a position near the hinge to be on or near the centerline of the movable case unit.

Electronic apparatus, display control method and recording medium

An image forming device includes an image forming part which forms an image on a recording medium; a recording medium switchback portion which receives the recording medium on a first run, one side of which has been printed when passing the image forming part, and sends the recording medium for a second run; a recording medium path which communicates with the recording medium switchback portion so as to send the recording medium to and from the recording medium switchback portion; an inverted recording medium transfer path through which the recording medium is sent to the image forming part again with an upper surface and a lower surface of the recording medium reversed; and a recording medium transfer part which transfers the recording medium along the inverted recording medium transfer path. The image forming device is further provided with a first recording medium receiving portion which stores the recording medium one on another with a printed surface facing upwards; and a first recording medium ejection path which communicates with the recording medium receiving portion so as to send the recording medium to the first recording medium receiving portion.

Image forming device

An ink cartridge connectable to a print head having a supply pipe which receives a supply of ink includes a casing having a first, upper chamber and a second, lower chamber communicating with each other via a communicating hole and storing the ink, a porous body provided in the first chamber and storing the ink by a negative pressure, and a connection part provided in the second chamber and connectable to the supply pipe. The connection part has normally closed valve means for communicating the print head with the second chamber by opening when the supply pipe is inserted into the connection part. The ink cartridge includes a connecting pipe extending from the first chamber into the second chamber and a filter member covering the opening of the connecting pipe in the second chamber. The filter member releases air from the connecting pipe upwardly into an upper region of the second chamber.

An image forming device includes an image forming part which forms an image on a recording medium; a stacker which stores the recording mediums one on another; a recording medium switchback portion which receives the recording medium on a first run, one side of which has been printed when passing the image forming part, and sends the recording medium for a second run; an inverted recording medium transfer path through which the recording medium is sent to the image forming part with an upper surface and a lower surface of the recording medium reversed; a recording medium transfer part which transfers the recording medium along the inverted recording medium transfer path; a recording medium position correcting part, located at the inverted recording medium transfer path, which corrects a position in a width direction of the recording medium, and a control means for controlling the recording medium position correcting part with a particular operation timing so that the recording medium position correcting part is operated while the printing means is transferred along the inverted recording medium transfer path by the recording medium transfer part.

Dual-sided image forming device with improved recording medium

A backup unit is provided with respect to a nozzle of a print head for printing by injecting ink, and sucks the ink from the nozzle, the backup unit including: a nozzle cap sealing the nozzle by making contiguous contact with the print head; a pump; and an ink path communicating the nozzle cap and the pump; wherein the pump includes: a bellows part having an internal space formed therein; a movable rod fixed to the bellows part and having an ink passage therein; a slide valve provided in the bellows part and slidable with respect to the rod, the slide valve closing and opening a hole provided at one end of the ink passage with respect to the internal space, depending on a position of the movable rod; an ink inlet provided at the other end of the ink passage and communicating with the ink path; and an ink outlet communicating with the internal space depending on a position of the slide valve, the slide valve having a stroke shorter than a stroke of the rod, a volume of the internal space within the bellows part increasing and decreasing as the slide valve makes a reciprocating motion in a direction parallel to a center axis of the rod, the slide valve sucking the ink from the nozzle via the ink inlet by opening the hole of the ink passage to the internal space when the rod is at a position where the volume of the internal space is a maximum, and discharging the ink in the internal space via the ink outlet as the volume of the internal space decreases.
