Title: Sliding plate fitting device
Inventor: INAGUCHI TETSUYA
IPC: G11B21/02
Filed: 1986-01-30
Abstract: PURPOSE:To freely move a fitting device up to the prescribed position on a sliding plate by providing a ring with plural small holes, cutting a space between these small holes and a hole in the center and inserting the ring into the upper part of a supporting shaft. CONSTITUTION:The sliding plate 3 can move in a direction D while its horizontal direction and vertical one are regulated by the supporting shaft 2 and a group comprised of the ring 11, a washer 4, a substrate 5 and a washer 6, respectively. Since a slit 11c does not reach an outer periphery, it has no step. Accordingly some part of the ring 11 does not contact the end part of the hole 11a on the sliding plate 3, which can freely move up to the prescribed position. As the slit 11c does not reach the outer periphery, it is impervious to impact. Besides the ring 11 is provided with a circular small hole 11b on the tailing end of the slit 11c, said hole 11b distributes the concentration of stress due to the slit 11c, whereby the mechanical strength of the ring 11 can be improved.

Abstract: PROBLEM TO BE SOLVED: To automatically select an image processing corresponding to the situation in the image input. SOLUTION: A data separating device 10 separates input data into image data and non-image data indicating the attribute, and supplies the separated non-image to a non-image information recognizing device 12, and supplies the separated image data to a masking device 18. The device 12 recognizes a zoom position and a focal distance at the time of photographing from the non-image data by dividing it into three cases. A photographic situation judging device 14 judges a photographic situation, for example, 'portrait' or 'landscape' according to the recognized result of the device 12.  In the case of the 'portrait', a color processing coefficient selecting device 16 sets a color processing coefficient under the great consideration of skin color reproduction in a masking device 18, and in the case of the 'landscape', the color processing coefficient selecting device 16 sets a color processing coefficient under the great consideration of green system reproduction in the masking device 18. The masking device 18 color-corrects the image data from the data separating device 10 by the masking processing corresponding to the set color processing coefficient.
