| 英文摘要 | PURPOSE:To set a density peculiar to a user by constituting the titled device so that a reference value can be freely set without executing the adjustment of a voltage dividing resistance, and also, the laser beam quantity can be varied in accordance with a ratio set manually at the time of replacing a drum. CONSTITUTION:As for a terminal 35, a light quantity control start signal APCST is applied and inputted to the input port I4 of a microcomputer 14, and as for terminals 36-38, light quantity switching signals S1-S3 are applied and inputted to input ports I1-I3 of the microcomputer 14. As for a changeover switch 39, when this changeover switch 39 is on, an automatic mode for determining automatically a light quantity set value is set, and when said switch is off, a manual mode for making the light quantity set value variable manually is set. A variable resistor 40 being a variable means inputs an analog input AN1 which becomes a manual reference value, to the internal memory of the microcomputer 14, when the changeover switch 39 is off. In this regard, the output of an operational amplifier 13 becomes the analog input AN2 of the microcomputer 14. |
