Patent number: 5737149Abstract: A floppy disk drive having a drive lever for driving a floppy disk. The drive lever is made from a low-cost metal plate and is elastically supported by a coil spring, thereby reducing the manufacturing cost. The drive lever has an arcuate shape which is bent inwardly in such a manner that an outward force of the drive lever is increased, thereby reducing friction and abrasion of the driving pin. The floppy disk drive has a rotor case of a driving motor, and a drive lever disposed at an inner bottom portion of the rotor case. The drive lever has a first end at which the driving pin protrudes through an opening in the rotor case, and a second opposite end which is secured to the case by a screw surrounded by the coil spring. Due to the coil spring, the drive lever offers elastic resistance when the driving pin is engaged in an engagement hole of a floppy disk hub. The drive lever is straight or has an arcuate shape which is bent inwardly.Type: GrantFiled: August 6, 1996Date of Patent: April 7, 1998Assignee: Samsung Electro-Mechanics Co., Ltd.Inventor: Seong Ho Shin
