Patent number: 5621585Abstract: A reel brake device in a recording and reproducing apparatus is operated by a tape loading mechanism. A cam portion is formed on any one side of at least one of a pair of loading gears employed for driving a pair of tape guide units which draw a tape from the cassette. The reel brake for braking the reels includes a friction member for braking the supply reel table and an operating portion which comes into contact with a cam surface and a cam protrusion surface of the cam portion selectively so that it may be driven. Under a tape unloading condition, the reel brake performs braking or releasing operation of the reels as the loading gear rotates in a predetermined direction. Driving of the reel brake by the existing loading gear without using any separate driving element, makes it possible to maintain the brake stroke, enhance the accuracy in operation, and reduce the number of elements constituting the supply reel brake device.Type: GrantFiled: December 22, 1995Date of Patent: April 15, 1997Assignee: Goldstar Co., Ltd.Inventors: Seong-Sik Kang, Sung-Hoon Choi, Myung-Cheol Baek, Sung-Pyo Hong, Ji Y.

Patent number: 5521775Abstract: A fast running mode conversion device for magnetic recording and reproducing apparatus. This device has a shaft supporter provided on the bottom surface of a base plate. An idler lifting lever for lifting or lowering an idler arm is pivotally mounted on the shaft supporter. A drive arm for driving the idler lifting lever is rotatably mounted on a shaft of the base plate. A biasing member coupled to the drive arm has a biasing lever for driving the idler lifting lever. The biasing lever extends toward the idler lifting lever. A function plate rectilinearly reciprocates by the rotating force of a cam gear, thus to turn the drive arm. The drive arm has an operating pin and the function plate has a pair of cam projections for cooperating with the operating pin when turning the drive arm.Type: GrantFiled: September 20, 1994Date of Patent: May 28, 1996Assignee: Goldstar Co., Ltd.Inventors: Seong-Sik Kang, Sung-Hoon Choi, Myung-Cheol Baek, Sung-Pyo Hong, Ji Y.

Patent number: 5507404Abstract: A color electroluminescence(EL) display element and the manufacturing method thereof which can improve an RC-time delay phenomenon and the contrast of the EL display element. According to the EL display element, an auxiliary metal electrode is formed on a transparent electrode. The auxiliary metal electrode is formed by forming on the transparent electrode a metal film having a high melting point and a low resistivity, such as molybdenenum, with a thickness of about 1000 .ANG., and then by selectively etching the metal film so that it remains on the boundary between each of R, G, and B color filters with a width of about 5 to 30 .mu.m. The color filters are formed on a circular polarizing plate and sealed up with the auxiliary metal electrode, and thus the circular polarizing plate absorbs an external light incident to and reflected from a metal electrode.Type: GrantFiled: October 28, 1994Date of Patent: April 16, 1996Assignee: Goldstar Co., Ltd.Inventor: Jae H.
