IPC: G03G15/00
Filed: 1983-12-22
Abstract: PURPOSE:To eliminate the need for preliminary scanning of original density and to control the quantity of lamp light to the quantity optimum for an exposed original region by inputting the output from an original density sensor provided on the upstream side of the exposing region in the original scanning direction to a circuit for dimming the quantity of the lamp light after delaying said output. CONSTITUTION:The density of an original 1 is detected by a sensor 9 provided on the upstream side in the scanning direction (a) where the light illuminated from a lamp 3 and reflected from the original is irradiated via a projecting optical system such as a mirror 4 or the like onto a photosensitive drum. A lamp power source is switched according to the detected value, by which the illuminance of the lamp is adjusted. Since there is a time delay until the certain part of the original detected by the sensor 9 arrives at the position under the exposing region, the output of the sensor 9 is passed through a delay circuit and is then put into a dimming circuit. However, there is also the delay in actual change in the quantity of the lamp light after the lamp voltage is changed and therefore the delay time is determined by taking such delay into consideration.

Abstract: PURPOSE: To display blank data above and below display data as much as a necessary number of lines without making the operation speed fast by making an N-fold display of the blank data longitudinally by making a longitudinal scan N time as fast as a display part, and minimizing the amount of the blank data. CONSTITUTION: A fast line clock generating device 11 generates a fast line clock which is N time as fast as before and a head line signal converting device 15 converts a head line signal and outputs a fast head line signal in timing matching the fast line clock.
