Abstract: PURPOSE:To prevent the entry of a material which contaminates mirror surfaces of a polygon mirror held on a rotating shaft by setting the gap between the bottom surface of the polygon mirror and a dust-proof member greatar than the gap between the top surface opposite to the bottom surface and the dust-proof member.

Filed: 1995-06-27
Abstract: PURPOSE: To track a mobile object with high accuracy by fetching the output information from a gyro sensor and correcting the temperature drift of the gyro sensor after input of a stop signal that is produced by the side brake of the mobile object. CONSTITUTION: A control unit 5 decides whether a mobile object is at a standstill based on the ON/OFF signals of a side brake. If the mobile object is at a standstill, the receiving level of the IF signal detected by a receiving level detector 4 is stored and the correction value is calculated as the value equal to the gyro sensor output and the gyro sensor original point voltage. Then the tracking of a BS antenna 1 is discontinued by the unit 5. If the mobile object is not stopped when a power supply is applied, the correction value is estimated from the mean output of a gyro sensor 8 during execution of the step tracking. Then the antenna 1 is tracked based on the estimated correction value. When an ON signal is inputted from the side brake, the correction value is updated and the peak value is stored. Then the tracking of the antenna 1 is discontinued.
