Title: Method for driving optical modulating element
Inventor: OKADA SHINJIRO
IPC: B41J2/44
Filed: 1986-05-06
Abstract: PURPOSE:To improve the latent image forming characteristic of a photosensitive drum and especially generate a gradation print picture by impressing an alternating waveform voltage to picture elements on non-selected scanning lines to equalize the polarity of a time average value of the alternating waveform voltage to that of a signal which sets picture elements on a selected scanning line to the bright state.

When a liquid crystal layer is made thinner, the helical structure of liquid crystal molecules is broken and they have a non-helical structure though an electric field is not impressed and their bipole moment Pa or Pb is in an upward state 34a or a downward state 34b. If an electric field Ea or Eb different in polarity which is higher than a certain threshold is applied to this cell by a voltage impressing means 31a or 31b, bipole moments Pa and Pb are changed to the upward state 34a or the downward state 34b in accordance with the field vector of the electric field Ea or Eb. Thus, liquid crystal molecules are oriented in either of one stable oriented state 33a and the other stable oriented state 33b.

Abstract: PURPOSE:To adjust the luminous amount of lighting by changing the ratio of the lighting time during one scanning period (duty cycle) in a raster scanning system device where a charge coupling element CCD is used as a read element and fluorescent light or the like is used as a lighting source. CONSTITUTION:A lighting time control circuit 5 consists of a time 5a starting cunting a clock signal CLK with a main scanning synchronoizing signal (s) and generating a carry signal when a clock corresponding to a setting time (t) is counted and a flip-flop FF5b set by the main scanning synchronizing signal (s) and reset by a carry signal of the timer 5a, and applies start/stop of an inverter 1 with an output signal of the flip-flop 5b. A control circuit 8 gives a setting time (t) in response to the detection signal from a sensor 9 detecting the lightness of fluorescent light 3 to the lighting time control circuit 5. That is, fluorescent light 3 is lighted at each main scanning and extinguished when the time reaches the set time (t) of the timer 5a by the control circuit 8. Since the time (t) set to the timer 5a is set in the unit of a clock signal, luminous amount is adjusted optionally substantially.
