Abstract: An image recording apparatus includes a recording section having a head holding member holding a plurality of head units ejecting ink, and a position adjusting mechanism including position adjusting members, each being provided for each head unit, for adjusting a position of the head unit relative to the head holding member according to movement thereof, a driving mechanism for generating a force moving the position adjusting member, and transmission mechanisms, each being provided for each position adjusting member, for transmitting the force generated by the driving mechanism to the position adjusting member, the driving mechanism selecting the transmission mechanism to be transmitted with the force from the plurality of transmission mechanisms to supply the force to only the selected transmission mechanism.

Abstract: An image recording apparatus comprises a plurality of drums for holding a recording medium on their perimeter faces and for being able to rotate the recording medium, and printing unit, which are arranged as opposed to the perimeter faces of the drums, for being able to make printing on the recording medium. A tension generating unit for applying a tension to the recording medium is arranged in the upstream and the downstream of the drums on the conveyance path of the recording medium. A drum in the downmost stream side of the conveyance path is used as a driving drum, and the other drums are used as driven drums.

Abstract: An image recording apparatus includes first and second drums configured to transfer a recording medium, first and second recording sections arranged in opposition to the first and second drums, respectively, and each including a recording head configured to record an image on the recording medium, and a main body frame configured to rotatably support at least the first and second drums, and when replacement of the recording head is to be carried out, each of the first and second recording sections is moved in a direction perpendicular to an axial direction of a rotating shaft of corresponding one of the first and second drums, and in horizontal direction.

Abstract: An image recording apparatus includes a rotational drum for retaining a recording medium on an outer circumference of the drum; a head retention member placed opposite to the outer circumference of the drum, for retaining a print head printing on the recording medium by jetting ink from a plurality of nozzles; and a support member for supporting the head retention member at a prescribed position in relation to the drum, the support member being engaged with the rotation shaft of the drum.

Abstract: An image recording apparatus includes two drums, where such a configuration is adopted that both an approaching or spacing direction of a first recording head section corresponding to a first drum of the drums and an approaching or spacing direction of a second recording head section provided corresponding to a second drum of the drums coincide with a width direction (an X-direction) of a recording apparatus main body and are parallel to each other, and a space required by the first recording head section at a spacing completion time and a space required by the second recording head section at a spacing completion time overlap with each other as viewed from a Y-direction.

Abstract: An image recording apparatus comprises a plurality of drums for holding a recording medium on their perimeter faces and for being able to rotate the recording medium, and printing unit, which are arranged as opposed to the perimeter faces of the drums, for being able to make printing on the recording medium. A tension generating unit for applying a tension to the recording medium is arranged in the upstream and the downstream of the drums on the conveyance path of the recording medium. A drum in the downmost stream side of the conveyance path is used as a driving drum, and the other drums are used as driven drums.

Abstract: Comprised are a rotational drum for retaining a recording medium on the outer circumference of the drum; a head retention member, being placed opposite to the outer circumference of the drum, for retaining a print head printing on the recording medium by jetting ink from a plurality of nozzles; and a support member for supporting the head retention member at a prescribed position in relation to the drum, in which the support member is engaged with the rotation shaft of the drum. Such a configuration makes it possible to reduce a variation of the relative position between the head retention member and drum and improve a print quality.

Abstract: A head-mounted image display device consists mainly of an image producing unit (2), right and left frames (27 and 25), and a controller (8). The image producing unit has image display LCDs enclosed with covers (11 and 12). The right and left frames useful in wearing the head-mounted image display device HMD on the head are supported by frame supports (17 and 16) that are fixed to the cover (11). Herein, the right and left frames are detachably attached to the frame supports. An earphone cord (21 or 20) is guided along ribs which are formed on the outer surface of the right or left frame. An earphone (7 or 6) is detachably attached to an earphone holder formed in the distal or rear portion of the right or left frame. Thus, there is provided a head-mounted image display device that is compact, that can be readily worn on the head, and that not only enables viewing of a display screen image but also simplifies observation of an ambient environment.

Abstract: An optical pickup comprises a plurality of light sources for generating recording and reproducing light of information, a plurality of optical elements for treating light beam generated from the light sources, light detecting means for detecting light beam in a optical path to adjust various characteristics of the light beam, and a recording medium, wherein resolution or resolving power in recording time and in reproducing time is adjusted to match to each other.
