Noise-reducing resonator and laser-scanning unit with the same

Abstract

A noise-reducing resonator and a laser-scanning unit with the same are provided. The noise-reducing resonator includes: a case having at least two spaces divided by partitions, and one side of which is open; and a cover fixed to the opened side of the case and having at least two holes for communicating each of the spaces with the exterior. An image forming apparatus having a lower operating noise than the conventional art, because the noise may be effectively reduced at a plurality of frequency bands rather than one frequency band. In addition, the resonator may be integrally formed with the laser-scanning unit and formed using the ribs formed at the main body of the laser-scanning unit, thereby reducing the number of parts and facilitating its manufacturing.
