Abstract: A document camera includes a base, a monitor display mounted on the base, a first arm, a second arm, and a camera head. The first arm is mounted to the base so as to be pivotable in a right-left direction. The second arm is mounted to the first arm so as to be pivotable in the right-left direction. The camera head is mounted to the second arm so as to be pivotable in the right-left direction. The arms and the camera head are laid into respective laid positions when the document camera is not in use. The arms and the camera head are raised into respective standing positions when the document camera is in use. When laid into the respective laid positions, the arms and the camera head are fit within an upper surface of the base, and the monitor display is substantially covered by the first arm.

Abstract: A document camera includes a base, a first arm assembled to the base, a second arm assembled to the first arm, and a camera head assembled to the second arm. The first arm is pivotable between a parallel extending position and a raised position. The second arm is pivotable between a juxtaposed position and a raised position and between the raised position and a parallel extending position. The camera head is pivotable between a juxtaposed position and a position where the camera head is raised from the second arm. When the document camera is to be folded, the first arm is set to the parallel extending position, the second arm and the camera head are to the respective juxtaposed positions. When the document camera has been folded, upper surfaces of the first and second arms and the camera head are substantially coplanar.

Abstract: A material imaging apparatus includes a base, support pillar and imaging camera divided into a camera base and a camera neck. The camera is mounted via a first shaft on the pillar so as to be pivotable between a right horizontal position where an imaging lens is located on a base right side and a left horizontal position where the lens is located on base left side. The camera neck is mounted via a second shaft on the camera base so as to be rotatable between a downwardly vertical position where when the camera assumes the right or left horizontal position, the lens is directed to the base placement surface side and lens optical axis is substantially vertical to the base placement surface, and an upwardly vertical position where the lens is directed to a side opposite the base placement surface and the optical axis assumes a substantially vertical position.

Abstract: A visual presenter includes a base, first and second column supports and a video camera head. The base has an upper surface formed with an accommodation recess located substantially at a central part of the upper surface. When the column supports and the camera head are in respective accommodation positions, the second column support and the video camera head are configured to lie along a front surface of the first column support. The column supports and the video camera head are configured to be accommodated in the accommodation recess. Upper surfaces of the second column support and the vide camera head are substantially co-planar with an upper surface of the base.

Abstract: A drawing system includes a pointing device, a control unit and a drawing unit drawing a line of trajectory of the cursor and including a straight line input assisting unit. The assisting unit includes a start point recognizing unit, an end point determination unit and a coordinate aligning unit. The start point recognizing unit recognizes as a start point an initial coordinate having an input position designated by the coordinate input unit. The end point determination unit determines as an end point a last coordinate having an input position designated by the coordinate input unit. The coordinate aligning unit aligns the coordinates of the primary coordinate group on a single line connecting between the start and end points thereby to form a secondary coordinate group. When a line is drawn based on the primary coordinate group, the line is corrected to a straight line based on the secondary coordinate group.

Abstract: A surveillance television camera including a camera base which is mounted on an installation surface and to which a surveillance television camera is mounted, a dome cover which is detachably attachable to the camera base and a locking device including a movable locking member mounted on the camera base and an elastic member biasing the movable locking member toward a joint surface of the movable locking member relative to the dome cover. The camera base has a joint surface relative to the dome cover. The dome cover has a fitting recess formed in the joint surface. When the joint surfaces of the camera base and the dome cover are joined together so that the dome cover is turned circumferentially thereby to be attached to the camera base, the movable locking member is fitted into the fitting recess of the dome cover by a biasing force of the elastic member.

Abstract: An electronic magnifier includes a stage on which an object to be read is placed, an imaging unit which is disposed above the stage to image the object, a liquid crystal display (LCD) monitor which is mounted via a pivoting member to the imaging unit so as to be pivotable, wherein the LCD monitor is configured to be accommodated in a space defined between the imaging unit and the stage.

Abstract: An attachment connects an eyepiece lens tube of microscope and an imaging lens tube of visual presenter and includes a cylindrical part loosely fittable through an opening with the eyepiece lens tube, a circular receiving surface which is formed on the cylindrical part and which a distal end of the imaging lens abuts, the receiving surface having a through hole, an indication line indicative of a center of the hole, a positioning piece standing along an outer circumferential edge of the receiving surface and having an inner circumferential surface with a curvature radius substantially equal to a curvature radius of outer circumference surface of the imaging lens tube, the outer circumferential surface of the imaging lens tube, and at least three screw members which are threadingly thrust radially through a circumferential surface of the cylindrical part into the cylindrical part, the screw members being arranged equiangularly.
