| 英文摘要 | A light quantity control device suitable for use in a laser beam printer includes a beam generator (11), a monitor (13) for monitoring the quantity of light of a beam generated by the beam generator (11), and a controller (2). The controller (2) controls the light quantity of the beam generated by the beam generator in response to the output of the monitor (13). The controller (2) includes a digital value output circuit and a light quantity control circuit (7). The digital value output circuit outputs a digital value representing the quantity of light of the beam, and the light quantity control circuit controls the quantity of light in response to the digital value. The digital value output circuit varies the timing of output of the digital value in accordance with the output of the monitor (13). |
