Abstract: In an optical disc apparatus, a harsh blow sound due to collision of first stoppers of a tray and third stoppers of a main chassis when the tray reaches to a terminal position of drawing thereof is reduced. When a second stopper of the tray contacts with the front end portion of a cam slider, the front end portion of the cam slider is elastically deformed so that moving speed of the tray is largely decelerated. Consequently, the blow sound due to contact of the first stoppers of the tray and the third stoppers of the main chassis is radically reduced.

Abstract: A tray-constrained mechanism of optical disk drive is proposed. This mechanism, consisting of a resilience part, forms an elastic constraint between the resilience part and a lateral wall on the protrusion part of bottom case, in order to constrain a tray and to reduce vibration generated by a spindle motor. Furthermore, because this mechanism contains only one resilience part, it can reduce both material cost and manufacture cost.
