Abstract: In a pantagraph-type jack, a lower reinforcement plate is integrally provided at an inner end of a bottom plate portion of each lower arm so as to extend therefrom in parallel with a corresponding lower pivot, and a lower recess is formed in an upper surface of a flange portion of each lower enforcement plate so that the lower recess receives a part of an outer peripheral surface of a threaded rod when a load bearing platform is lowered to a lowermost position. Also, an upper reinforcement plate having the same structure is integrally provided at an inner end of an upper plate portion of each upper arm. Thus, it is possible to firmly restrict inward falling of side plate portions of the lower arms and upper arms, and to lower the load bearing platform to a lowermost position without interference by the above-described reinforcement structure.

Thus, a frictional torque is minimized between the lower arms and the base as well as between the upper arms and the load bearing platform when the load bearing platform is raised and lowered, and a support strength of the lower arms with respect to the lower pivots and a support strength of the upper arms with respect to the upper pivots are enhanced.

Abstract: A process computes a combination of chromatic and achromatic color dots for reproducing an input color signal based on a result of colorimetric measurement for a CIELab value. The process finds the sum of chromatic and achromatic color dot diameters. The process extracts combinations of chromatic and achromatic color dots wherein the sum of chromatic and achromatic color dot diameters is greater than or equal to a specified value. From the extracted combinations of chromatic and achromatic color dots, the process further extracts chromatic and achromatic color signals for recording a combination of chromatic and achromatic color dots containing the minimum achromatic color dot diameter and determines these signals as a color signal.
