Title: Scanner
Inventor: OHASHI TSUTOMU
IPC: G03G15/04
Filed: 1989-03-31
Abstract: PURPOSE:To shorten the time from the time of an image forming command before the start of the image formation or the time before the recovery from a step out is made when the step out arises by converging the operating speed of a 1st scanning means to a reference speed, then driving a 2nd scanning means according to the operating condition of the 1st scanning means. CONSTITUTION:A driving circuit 34 rotates a polygonal mirror driving motor 24 when a switch for the image formation is turned on. The polygonal mirror rotation signal from a photointerruptor 26 and the reference signal from a reference signal oscillator 32 are introduced to a phase comparator 31 by which the phase difference is calculated. The rotating speed of the polygonal mirror is converged to a prescribed speed in accordance therewith. On the other hand, a drum rotating motor 13 is started to run by a driving circuit 39 simultaneously when the switch turns on. An electronic switch 35 is changed over when the output of the comparator 31 turns to zero and the rotating speed of the polygonal mirror converges to a prescribed speed. The drum rotation signal from the photointerruptor 15 and the polygonal mirror rotation signal from the photointerruptor 26 are then compared by a phase comparator 37.

Abstract: PURPOSE:To prevent sheets of paper or the like from being overlooked by equipping a detecting means for detecting the sheets of paper or the like remaining in a classification box after the sheets of paper or the like have been taken out from the classification box. CONSTITUTION:When classification of mails P has been thoroughly completed, these mails P are taken out from the classification boxes 6... respectively. Thereafter it is recognized by visual observation of an operator that the mails P have been thoroughly taken out or not from the classification boxes 6.... Then a switch is turned on in order to change over to a residual check mode provided to an operation part, Thereby light is emitted from a cell 8 for light emission and interrupted by the mails P when these are allowed to remain. Therefore a cell 9 for light reception can not receive light. When the call 9 does not receive light, the number of an indication part 20 is lighted and indicated which is correspondent to the row of the classification box incorporating the residual mail. Thereby the mail is surely prevented from being left as it stands.
