Title: Innovations of Yu-Ming Chang
Introduction
Yu-Ming Chang is a notable inventor based in Guishan Shiang, Taiwan. He has made significant contributions to the field of optical disk drives, holding a total of 2 patents. His work reflects a commitment to advancing technology in this area.
Latest Patents
One of his latest patents is for a slot-in optical disk drive. This invention features a clamping unit with two protrusions that fastens around the central hole of a base plate. A front positioning part utilizes a stick to link a front right positioning bar and a front left positioning bar, allowing them to open or close synchronously. Additionally, a locking rod with a limiting pin is inserted into an arc slot on the side of the base plate, which protrudes a locking end from the rear. The rear positioning part employs an idle gear to link the rear right and rear left positioning bars for synchronized operation. The locking end can insert into a first or second positioning recess on the rear left positioning bar, while a touch block of the locking rod leans against the first protrusion. A lever is also included on the rear right positioning bar to link a linkage plate set by one end.
Another patent by Yu-Ming Chang is an emergency ejection device for a slot-in optical drive. This device utilizes a feeding motor to rotate a transmission shaft from one end without self-locking. The other end of the transmission shaft extends to the front of the drive, forming a pincer-like slot. A worm is positioned between the two ends, and one end of a gear set drives a clamping unit while the other end rotates a roller. A worm wheel is engaged with the worm, allowing the transmission shaft to be rotated by hand to eject a disk.
