Abstract: A multi-purpose computer work aiding board includes a board body, a rotary disk having a top face forming a mouse pad, and a substantially inverted U-shaped copy holding frame. A top face of the board body being provided with a plurality of recessed grooves of different sizes that are adapted to accommodate disks of different sizes in an upright position or to receive a mouse and stationery items. Four sides of a bottom face of the board body form struts such that, when the board body is placed in a position, a lower end of the board body forms a through space for receiving the rotary disk, a disk rim portion of the rotary disk forming a pivot mounting hole. The bottom of the board body is provided with at least one strut forming a pivot for insertion into the pivot mounting hole such that the rotary disk can be rotatably turned sideways into or out of the through space, a periphery of the top face of the board body forming a recess for receiving the copy holding frame.

Abstract: A disk organizer adapted to receive various types of disks includes a base, a cover pivotally connected to the base such that the cover is liftable from the base; and a plurality of disk clamps. Each disk clamp has a protrudent block projecting from either bottom end thereof. At least a row of clamp grooves are formed in the base. The lateral side walls of each clamp groove form multiple steps the thickness of which enlarges towards the bottom such that the space between opposite steps receives and holds the bottom angles at both ends of a disk inserted therein. Pairs of fastening recesses are formed at both sides of the base adjacent to the clamp grooves. The distance of any pair of fastening recess is identical to the distance between the protrudent blocks of the disk clamp so that the disk clamp may have the protrudent blocks thereof retained in the fastening recesses of the base and may slightly swing forwardly or rearwardly according to the positions of the fastening recesses.

Abstract: A CD container storage device includes a rectangular case and a cover wherein the rectangular case includes a rear wall, a top wall, a bottom wall and two lateral side walls and divided into two chambers by a vertical partition having a slot a front side thereof, and the cover is pivotally and slidably engaged with the rectangular case and has a hook member engageable with the slot.

Abstract: A CD bank including a rectangular casing having an upper portion and a lower portion engaged with the upper portion, the lower portion being formed at a lower edge with pairs of ears, each pair of the ears being provided with two opposite protuberances, a plurality of holders pivotally connected with a lower edge of the lower portion, each of the holders being symmetric in structure at both sides thereof and being formed with a through hole adapted to be fitted between the protuberances of a respective pair of the ears, each side of the holder being formed with a half-round recess of a diameter slightly longer than that of an compact disk, an opening at a central portion of the holder for facilitating removal of a compact disk, a plurality of retaining lugs suspending above the half-round recess and spaced around a periphery thereof and having a beveled edge facing inwards, a plurality of triangular projections spaced around the periphery and having a beveled edge facing outwards, a projection at a top of the

Abstract: A CD bank which includes a case, a transparent cover hinged to the case, and a plurality of individual CD holder plates mounted inside the case to hold individual compact disks respectively, wherein the case has two longitudinal rails bilaterally disposed on the inside, and longitudinally spaced pairs of transverse grooves respectively made on the longitudinal rails; the individual CD holder plates are respectively pivotably mounted in the longitudinally spaced pairs of transverse grooves between the longitudinal rails, each individual CD holder plate having a half-round recess for holding an individual compact disk, an extension board extending from the diameter of the half-round recess, an opening at the periphery of said half-round recess for the insertion of the thumb, an index groove at the extension board for mounting an index sticker, a plurality of retaining lugs suspending above the half-round recess and spaced around the border thereof for holding down an individual compact disk within the half-roun
