Latest Patents
One of Juman's latest patents is an optical memory apparatus that features a base with a unitary and integral optical component mounting portion. This innovative design allows for a miniaturized optical disc memory to be received in a slot, accommodating a height of about 17 mm, which is typically used for floppy disc drives. The base includes a base plate with integral sidewalls and an internal partition wall that defines a cartridge receiving slot. The design incorporates first and second support plates that extend from the partition wall, creating upper mounting surfaces and cavities for an ejection motor and a fixed optical system. This system is engineered to transmit a laser beam and receive a reflected beam along a central optical axis.
Another notable patent involves an optical data recording and reproducing apparatus designed for easy assembly. This invention aims to produce a compact optical disk drive unit that improves the efficiency of component assembly. The drive unit consists of a driving mechanism and a printed wiring board, which work together to load a cartridge containing an optical disk, drive the cartridge, and read or write data. The driving mechanism is divided into a load/ejection mechanism and a reading/writing mechanism, enhancing the overall functionality of the device.
