Abstract: PURPOSE:To prepare a plastic member having a shaft inlaying with a bearing hole with good accuracy by the reduced number of molds, by forming molds so that the burr generated at the position corresponding to the parting parts of the molds to the outside in a radius direction from the circumference of a circle. CONSTITUTION:Molds 44, 46 have circumferential parts 44a, 46a formed as molding surfaces respectively forming the halves of the circumference of a male screw to be molded and expanded parts are formed to the parts of the molds 44, 46 ranging to the parting face between both molds 44, 46, that is, both end parts of the circumferential parts 44a, 44b so as to be expanded to the inside in a radius direction. In this case, a screw molds are formed to the circumferential parts but the expanded parts have shapes largely expanded from the screw threads of the screw molds. When said molds 44, 46 are filled with molten plastic and the mold 44 is pulled upwardly while the mold 46 is pulled downwardly after curing, a screw is formed. This screw is formed so that the burrs at the places corresponding to the parting parts of the molds are not protruded from valley parts so as not to be contacted with the screw part.

Abstract: PROBLEM TO BE SOLVED: To provide a buffer which has capacity for securely storing picture data required for one main scanning operation of an output system and can realize high speed access, corresponding to the processing speed of the output system. SOLUTION: For reading picture data for one main scanning operation, a pair of DRAM 204A and 204B are used, picture data for one main scanning operation is divided and they are sent to a pair of SRAM 208A and 208B. Picture data are alternately transferred from SRAM 208A and 208B to an output system. Then, next picture data which are divided are stored in SRAM 208A and 208B which become empty. Thus, a pair of SRAM 208A and 208B are alternately connected to the output system and divided picture data are transferred. Consequently, picture data can be accessed at appropriate processing speed without giving the stress of waiting time to the output system. Thus, correspondence to the sharp increase of picturure data quantity based on high resolution, coloring and multi-recording is realized.
