  • Patent number: 4963986
    Abstract: An image input apparatus having a lens unit and a photoelectric transducer and includes an automatic exposure circuit for controlling an amount of exposure onto the photoelectric transducer so that it becomes a predetermined standard value, a correction circuit for modifying the standard value, and a reset circuit for converting a correction value corrected by the correction circuit into the aforementioned standard value. Also provided is a controller for selecting a first mode for modifying data representing an amount of light exposure on the photoelectric transducer, and a second mode for modifying data representing a focal length of the lens unit. The reset circuit further includes a common increase/decrease change-over switch for increasing and decreasing corresponding data in each mode selected by the controller.

  • Patent number: 4926196
    Abstract: An ink jet printer has a recovery system for sucking ink from nozzle orifices together with air bubbles stagnant in orifices so as to recover the normal state in the orifices. The recovery system has a vacuum generating device, a capping device and a valve mechanism for controlling the vacuum generated in the vacuum generating device to the capping device. The recovery system further has a temperature detector for detecting the temperature of the ink. The operation timing of the valve mechanism is controlled in accordance with the temperature of the ink detected by the temperature detecting means, so that the amount of ink sucked by the recovery system is regulated in accordance with the temperature of the ink.
