Abstract: An ink jet recorder that includes line heads (4) having a plurality of nozzle heads (41), main tanks (13) placed outside of the line heads (4) to store ink; an ink supply passage (13a, 49a, 49c) that connects the main tanks (13) to the associated nozzle heads (41), and distribution tanks (6) placed in each line head (4). The number of supply tube connections (67) provided in the distribution tank (6) is smaller than that of the nozzle heads (41) arranged in the line head (4).

Abstract: A plurality of long narrow rectangular plate like nozzle heads are inclined together in a direction relative to that in which they are disposed side by side in a line in the line head for permitting ink that also gets into gaps between adjacent nozzle heads to be wiped away.

Abstract: A developer feeder for wet developing apparatus having a developing roller rotationally engaged with a photoconductor drum and a feed roll in part immersed in a liquid developer and rotationally engaged with the developing roller for supplying the liquid developer onto the developing roller can be made to furnish the peripheral surface of the developing roller with the liquid developer even in thickness by using a plurality of feed rollers which are not mesh rollers but whose peripheral surfaces are smooth and which are arranged circumferentially of the rotational developing roller.

Abstract: For a line head in an ink jet recorder wherein the line head comprises a plurality of long narrow rectangular plate like nozzle heads which are inclined together in a direction relative to that in which they are disposed side by side in a line in the line head, the invention is designed to be capable of wiping ink as well that gets into gaps between adjacent nozzle heads. To this end, an elastically deformable blade 13 is used that is brought into pressure contact with nozzle faces of a line head 23 and moved in a direction in which nozzle heads 24 are inclined while maintaining the blade 13 under pressure to cause it to be deformed against the nozzle faces as it is moved. Also, contaminants adhered on the blade by the wiping action is flushed with cleaning liquid rather than by a contaminant removal member.

Abstract: In order to maintain ink supply pressure to a recording head constant while supplying the recording head with ink with an minimum of air entrained therein, the invention provides an ink supplier which comprises a main ink reservoir, a subsidiary ink reservoir connected to the main ink reservoir for replenishment with ink from the main ink reservoir and a means whereby a position head of the ink liquid level in the subsidiary ink reservoir is maintained substantially constant relative to a printing head face of the recording head. Included preferably also are a deaerator associated with the subsidiary ink reservoir for removing air from ink therein and a float floating on ink in the subsidiary ink reservoir.

Abstract: An electronic apparatus electrically connectable to an external member includes a housing that has an insertion opening, which the external member is inserted into and ejected from, an ejector which is provided movably on the housing, has a movable end that projects from the insertion opening, and projects the external member from the insertion opening as the movable end moves apart from the insertion opening, and a cover, attachable to the housing, which closes the insertion opening.

Abstract: An apparatus is operable to print both sides of a web using two sets of ink-jet printers. A first set of printers are aligned horizontally, and so are the second set, with a vertical spacing between the first set and the second set. Paid out from its roll, the web is first fed forwardly past the first set of ink-jet printers so as to be printed on one side thereof, then reversely past the second set to be printed on the other side. The web can be guided solely by parallel rollers without the use of turning bars.

Abstract: A magnetic display apparatus having a magnetic display sheet consisting of a plurality of microcapsules having oily liquid having photoabsorptive ferromagnetic powder and photoreflective non-magnetic powder, an apparatus for erasing with a magnet a line drawn on the display sheet by the magnetic pen, a magnet, a mechanism for moving the magnet along a major portion of the magnetic display sheet and a power source for moving the mechanism which supports the magnet.

Abstract: A magnetic pen for drawing lines on the main surface of a magnetic display sheet consisting of a plurality of microcapsules in which oily liquid having photoabsorptive ferromagnetic powder and photoreflective non-magnetic powder are mixed in sealed relationship, and wherein the magnetic pen includes a core member having a spherical crown shape, a magnet constituting part of a notched surface of the core member, the core member being supported by the pen such that the notched surface of the core member protrudes from the tip of the pen and a spherical contraposition is generated by a part of the spherical surface of the core member, and wherein the notched surface of the core member is brought into contact with the main surface of the magnetic display sheet by the force of a stroke drawing line.

Abstract: The drawing toy of the present invention includes: a paper retainer, to retain a piece of paper for drawing; a writing tool holder, for use in drawing on the paper; a first cam, keeping the information for moving the writing tool holder in a first direction along said paper; a second cam, carrying the information for moving the writing tool holder along the paper and in a second direction, perpendicular with the first direction; a cam driver, to drive the first cam and the second cam; and a drawing mechanism coupled to the first cam and the second cam, which moves the writing tool holder in response to the movements of both cams, whereby a drawing may be effected on the paper.

Abstract: A game device including a game plate having a predetermined track formed thereon and at least one piece resting portion provided by said track, a piece which can be rested on the piece resting portion. A running body is provided on the track and having a scooping-up member for scooping up game pieces. A scooping-up member operating mechanism for operating the scooping-up member, wherein the scooping-up member operating means includes a scooping-up driving mechanism for temporarily driving the scooping-up member in the vicinity of said piece resting portion. A restraining mechanism designed to intermittently operate so as to intermittently restrain a part of mechanical elements inside said scooping-up member driving mechanism from operating is also provided.

Abstract: A water toy is provided with play members in a game body which is at least partially filled with air. The water toy has a fountain generating mechanism for generating a stream of liquid in the air of the game body to propel the play members through the air. The play members may be caught by receiving elements.
