Abstract: A table which can be easily assembled without much labor for screw fastening or such operations is provided. For this purpose, pins are provided on lower portions of the inner surfaces of both side frames which constitute the table, and slots are formed in upper portions thereof and opened upwardly, while slots which are opened downwardly to be closely fitted on the pins of the side frames are formed in lower portions of a rear frame on both sides, and pins to be closely fitted in the slots in the upper portions of the side frames are provided on upper portions of the rear frame on both sides. The rear frame is connected to both the side frames.

Abstract: An apparatus to isolate vibration during printing by a printer of a computer or a word processor, including vibration control swingable devices provided at their bearing portions, where the printer is mounted, with concave-surface bases extending in parallel to a direction of movement of a printing head of the printer and with rollers connected to the bearing portions which operate rolling motion on the concave-surface bases. The vibration control swingable devices may also include swing mounts for swinging the bearing portions in parallel to the direction of movement of the printing head. Thus, the vibration caused by the printer during printing can be isolated from other associated instruments.

Abstract: This invention relates to a relatively smallsized computer mount carrier rack which can be collapsed when it is housed, stored or conveyed. The carrier rack has such a structure that a computer mount panel is connected to the rear frame structure pivotable around a common axis of both-side joints and slidable by a pair of pins of the joints with respect to left and right columns of the rear frame structure, the rear frame structure is provided with left and right side frame structures which are connected thereto by pivotable joints and collapsible one over the other by rotating them around the axes of the joints so as to overlay the side frame structures on the rear frame structure and deform three structures into triple layer, and that the folded computer mount panel is received within a space defined by the rear frame structure and the collapsed side frame structures, thereby deforming the whole of the disassembled carrier rack into planar configuration.
