A recording or reproducing apparatus for recording or reproducing information by relatively moving a head and a sheet recording medium is disclosed. The recording or reproducing apparatus includes a stabilizing member disposed around the head and arranged to generate pressure which brings the recording medium into contact with the head in accordance with the rotation of the recording medium. The stabilizing member includes a first projection portion having a projection surface projecting toward the recording medium, a second projection portion disposed outside of the first projection portion via a groove portion formed outside the first projection portion, the second projection portion having a projection surface projecting toward the recording medium, and a cut portion formed in a portion of the second projection portion downstream from the head in a direction of rotation of the recording medium, the cut portion being formed by cutting the second projection portion from its surface which confronts the recording medium, and the depth of the groove portion with respect to the recording medium being reduced from the outer portion of the stabilizing member to the inner portion of the same.

An ink jet recording apparatus having a conveying unit for conveying a recording medium to be recorded on, a body unit including an ink containing unit mounting section for mounting an ink containing unit for containing ink to be supplied to a recording head and a cassette mounting section for mounting a cassette for supplying the recording medium. Also provided are a recording unit including a recording head mounting section for mounting the recording head, a carriage unit for moving the recording unit in a predetermined direction, a recovery unit for restoring an ink discharge function, an electrical power source unit for actuating the ink jet recording apparatus, and an electrical circuit unit for controlling the conveying unit, the recording unit, the carriage unit and the recovery unit. The recording head mounting section and electrical circuit unit are provided within the body unit and the ink containing unit mounting section is provided at a position lower than the recording head mounting section and below the electrical circuit unit.

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.

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.
