Filed: 1990-01-25
Abstract: PURPOSE:To attain the edit processing with a few memory capacity without contradiction by expanding edit processing information into a matrix shaped edit map sectioned by a main scanning and a subscanning when plural rectangular areas are edited. CONSTITUTION:A CPU accesses a memory 401 and brings an MSEL signal to zero to access a memory 402 by a CCD address to start the scanning of an optical system. When the edit is implemented according to one memory bank, the CPU sets an edit data of a prescribed line of an edit map M(a,b) into a memory bank (j). Then this is implemented till the optical system reaches a prescribed end point Ymax in the subscanning direction and stops. Thus, the edit processing is attained by taking the designated order or degree of overlap of plural areas into account without contradiction by constituting an edit map comprising each change point coordinate table in the main scanning and the subscanning in all areas to be designated and a pseudo bit map memory corresponding to the change point.

Title: Vibrating motor and driving method for vibrating motor
Inventor: HIGUMA KAZUYA
IPC: H02N2/00
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To make it possible to drive vibrating-wave motors with stability and reliability, by providing a switching means which switches between operation and non-operation of a control means according to driving conditions set on a condition setting means. SOLUTION: Eight-bit output values of a microcomputer 2 for setting frequencies for switching starting and driving conditions for individual vibrating motors 19 are stored in a rewritable storage means 36, and the vibrating motors 19 are controlled according to the stored values. Or, calculation is made from values in the rewritable storage means 36 to determine frequencies for switching starting and driving conditions. By switching driving conditions as mentioned above, current passed through output stage transistors can be reduced and thus power consumption can be reduced. If driving conditions are switched, driving frequencies are prevented by phase control from being restricted. As a result the state of driving of the vibrating motors 19 can be detected with accuracy, and thus the motors can be driven with stability and reliability.
