A loading device for a disk driver includes a transporting unit and a guide unit. The transporting unit includes one roller or two rollers, and the guide unit includes two symmetric or asymmetric cones. When loading a disc, two sides of the disc are individually supported on two cones of the guide unit. Two cones have different cone angles, equal cone angles but unequal lengths, or the same shape but different rotation velocities. The guide unit utilizes different arc speeds on two ends to obliquely convey the disc with any guide rails. The loading device reduces the cost of production and prevents the disc from generating collision and noisy.

A hinge positioning structure is used to couple a body and a leg of a stand. The hinge positioning structure has a joint groove formed in the body, a stopper attached at the bottom of the joint groove having an elastic body with a spring strip, and a hinge formed in the leg positioned in the joint groove. The leg has two sides, each side having a pivot positioned according to a corresponding pivot hole in the joint groove for rotatable insertion into the corresponding pivot hole of the joint groove, and two flanges, each flange parallel to the spring strip and radially protruding a first height sufficient to contact with the spring strip for generating a resistance.

A tray-type optical disc drive includes a base unit, an optical disc drive body, a front panel and a disc tray. The disc tray includes at least a retainer and a receiver. The receiver includes a horizontal bearing area, a ramp and a vertical bearing area. The ramp outwardly adjoins the horizontal bearing area while the vertical bearing area outwardly adjoins the ramp. The horizontal bearing area contacts with the outer edge of the disc when the disc is under horizontal disposition. The retainers are disposed on the receiver. When the disc is under vertical disposition, the retainers stop the disc edge for the disc to be positioned. The vertical bearing area and the retainer stop the lower edge of the disc edge. The upper edge of the disc edge leans against the horizontal bearing area.

Tray-type optical disc drive with improved reliability under vertical disposition

The present invention is a disk drive with an electrostatic discharge structure including a casing having a hollow space inside, and a tray with a spindle motor, which can freely insert into or pull out from the casing. A chassis covers the bottom of the tray and contacts the spindle motor. A bezel in the front of the tray has a hole to accommodate an eject button. A metal sheet is attached to the back of the bezel, surrounds the eject button, and connects with the chassis. A wire connects the spindle motor for grounding. The tray is able to discharge electrostatic charges whenever inserting into or pulling out from the casing.

The present invention is to provide an optical disk drive including a casing, a tray, a signal wire, and a conductive wire. The casing has a first electric device and a grounded conductor, and the tray has a second electric device and a base plate. The signal wire connects the first electric device and the second electric device. The conductive wire is a part of the signal wire to electrically connect the base plate and the conductor. When a user touches the tray, electrostatic charges of the user are grounded by the connection of the base plate and the conductor.

An apparatus for changing optical disks including a plurality of driving shafts, supported on the bottom plate of an optical disk drive, and a plurality of elastic devices. The driving shafts rotate synchronously around their vertical axes to raise and lower the trays. Each of the driving shafts includes a thread region, threads of which can be engaged with the trays, and an upright region located on the thread region. The pitch for threads in the upper thread portion is larger than that in the lower thread portion of the thread region. Each of the elastic devices has one end fixed to a top end of the upright region of the corresponding driving shaft or fixed beneath the top plate, and the other end provided together with the flat surface between the upright region and the thread region for clamping the trays in the range of the upright regions. Trays are also forced by the elastic devices by rotating the driving shafts to move along the thread from the position held at the upright region to that held at the thread region.
