Patent number: 6045233Abstract: It is made possible to locate arbitrarily a light guiding device and a light emitting means. A notch (11) having a triangular cross-section is formed on a bottom (inner) side of a light guiding device (10) formed so as to have a rectangular cross-section. Furthermore, a light emitting source (12) is provided under the notch (11) of this light guiding device (10). The light emitting source (12) is mounted on a circuit board (13), and controlled according to the state of control or setting in, for example, the electronic appliance. When the light ray from the light emitting source (12) is irradiated toward the notch (11), the emitted light ray is reflected by a reflective face (14) formed by the notch (11) so as to be a plane and a front face (15) of the light guiding device (10) becomes luminous. In addition, the irradiated light ray is partially transmitted through the reflective face (14), and a top face (16) of the light guiding device (10) also becomes luminous.Type: GrantFiled: January 6, 1998Date of Patent: April 4, 2000Assignee: Sony CorporationInventors: Yuji Iwai, Hideyuki Taguchi

Patent number: 5786933Abstract: A rear project cabinet for arear projection television set in which the screen and the mirror can be easily set in their positions and an optical accuracy can be established. The screen fixing segment and the mirror fixing segment constituting the rear projector cabinet are formed by plastic material in such a manner that each of its depth size and the inclination angle of the mirror may become a set value, thereby a well-focused appropriate screen can be attained by a mere coupling and assembling of these segments, and even in the case that the screen size at the screen fixing segment is different, it can be accommodated by applying a proper insert die during molding of the mirror fixing segment.Type: GrantFiled: June 18, 1996Date of Patent: July 28, 1998Assignee: Sony CorporationInventors: Yuji Iwai, Ryoji Naito, Masataka Onishi, Takayasu Ishikawa
