Title: Accumulator
Inventor: KANEAKI TETSUHIKO
IPC: H03H17/02
Filed: 1987-06-04
Abstract: PURPOSE:To prevent the generation of a distortion near zero by setting (M+1) bit (M<N)-th from the high order of the memory means of an N bit (N is a natural number.) to '1' at the time of starting the accumulation and starting the accumulation. CONSTITUTION:When a resetting signal RES comes to be '0', by a time slot 0, the output of AND gates 30-34 comes to be all zero and the output of an OR gate 41 comes to be '1'. Thus, full adders 11-16 output alpha0+128 and are latched to DFF21-26. By a time slot 1, the signal RES comes to be '1' the AND gates 30-34 and the OR gate 41 give outputs Y0-Y23 of DFF21-26 to the full adders 11-16. For this reason, by the time slot 1, the calculation of alpha0+128+alpha1 is executed. Thus, the accumulation is successively executed, the calculation of a formula is executed by a time slot 63 and by the continuous time slot 0, the output is executed from the DFF21-26. The DFF27-29 latch the high order 16 bit of the data by a clock signal CK2 and the output of the accumulator is obtained.

A 1st developing machine 23 is set in a non-developing state and the black toner image is formed by the 2nd developing machine 24 in the 1st image forming process. The black toner is then transferred onto the copying paper S. The photosensitive drum 20 is thereafter electrostatically charged by an electrostatic charger 21 in the 2nd image forming process. The electric charge of the other regions except the photosensitive body region corresponding to the assigned region of the copying paper is erased by an inter-image eraser 22. The 2nd developing machine 24 is then put into the non-developing state and the assigned region is developed with the white toner of the 1st developing machine 23. The copying paper S on which the black toner image is transferred is again conveyed to a transfer section T where the solid image of the white toner is superposed thereon. The images having the high gradation characteristic is thus formed and the stressing of a part of the images is possible.
