Auxiliary pressurizing plates 22 are stuck in the recesses of the dies 18 between the gates 16 by means of pressurizing bushings 19, springs 20 and supporting means 21. Molten metal is forced roughly uniformly from the part 15 thrugh the gates 16 into the cavities 13. In this stage, the pressurizing force of the molten metal is exerted upon the bushings 19, and presses the plates 22 via the springs 20, thus the molten metal in the cavities 13 is pressurized uniformly. The layers 17 contribute to solidifying of the molten metal in the gates 16 after solidification of the molten metal in the cavities 13 and to reduction in the remaining molten  metal in the gates. Thus the generation of defective cast products is decreased  and yield is improved.

Abstract: PROBLEM TO BE SOLVED: To reduce reading abnormality by reading a pre-printed reading start mark and changing that reading start position at the time of retrying reading based on the detected result of that position deviation. SOLUTION: On an application form to be used for applying a ticket issue, for example, there are applicant description columns for name and age or the like, and the image reading start mark for starting reading those description columns is pre-printed. When an image reader 12 reads the application deviating the position of start mark to right, for example, data are fetched into an image buffer as black bit data but in the other case, the data are fetched as white bit data. A position deviation detection circuit 39 searches black bits to be positioned in the retrieval range of start mark from the head of data in that image buffer and detects the deviated position at the time of reading. When retrying reading, an image reading circuit 35 changes that reading start position.
