Abstract: PURPOSE:To attain accurate identification and to render an image with high quality by identifying a halftone area from a character line drawing area from the size of a rectangle and a ratio of the number of picture elements of a binary image in the rectangle to that after extracting a contour setting the rectangle as identification unit. CONSTITUTION:A binarization processing is applied on image input data inputted with multivalues from a scanner, etc., by a binarization processing means 1. A rectangle forming processing to connect a black picture element is applied on a binarized image by a rectangle forming processing means 3, and also, after an isolated point is eliminated from the image by an isolated point eliminating means 5, the extraction processing of the contour is applied by a contour extracting means 6. An area judging means 8 identifies the character line drawing area from the halftone area from the size of the rectangle and the ratio of the number of binary black picture elements to the picture element whose contour is extracted. In such a way, it is possible to accurately identify a character line drawing image in a document image from a halftone image, and a satisfactory reproducing image can be obtained.

IPC: F16D65/18
Filed: 1989-04-05
Abstract: PURPOSE: To enhance brake responsiveness by interposing a clutch and a control member between a drive sleeve and a motion converting member, and transmitting force from an energy storing member to a force transmitting member in a controllable manner. CONSTITUTION: A coil spring 6 is pulled by operation of a motor 10. If reversal, rotation of the motor 10 is prevented by a one-way tightening spring 12, large torque is applied to a driving sleeve 8 in one direction. The sleeve 8 is normally fixed in such a manner as not to be rotated in the above-described direction by an outward tightening spring 16. In the meantime, when a control sleeve 17 is turned by a control motor 20, the spring 16 can be released since the spring 16 engages the sleeve 17. Consequently, the sleeve 8 can be freely rotated by the effect of the spring 6 until the sleeve 8 is fixed again to a housing 1 by the spring 16. During this rotation, since an inward tightening spring 18 is located in a fixing direction, rotation or torque is transmitted to a drive ring 13, to be transmitted toward a force transmitting member 4 in the axial direction.
