Abstract: In a beam scanning apparatus of an electrophotographic color printer, at least two beam deflectors, each having a deflection disk consisting of at least two sectors and a driving source for rotating the deflection disk, deflect and scan an incident beam. The deflection disk has a pattern formed thereon for diffracting and scanning the incident beam.

Abstract: A disk cartridge includes a case which receives a disk thereon, a cover which is installed on the case and includes an opening, and a shutter which is movably installed in the case, in a lower direction of the disk, to open and close an aperture formed on the case. The disk cartridge has guide holes formed on the case along a trace of the shutter, and support members formed on the shutter. The support members are guided along the guide holes while having ends thereof interfering with peripherals of the guide holes. Therefore, since the peripherals of the guide holes interfere with the ends of the support members, the shutter is prevented from being deformed even where an external force is applied to the shutter through the aperture, in a closed state of the shutter.

The opener is installed in the main body and elastically contacts a guide formed on the tray. The opener includes a second gear and a first protrusion. The second gear rotates a rotating wheel when in contact with a first gear. The first protrusion formed on a first end of the second gear temporarily rotates the rotating wheel so that the first and second gears can mesh. The guide has a first cam that moves the opener such that the first protrusion does not interfere with the latch when the tray is loaded/unloaded.
