Title: Led emitter unit
Inventor: INAZU SHINSUKE
IPC: F21V8/00
Filed: 1995-04-06
Abstract: PURPOSE: To freely set the lighting area with the scattering effect of light, and to eliminate a LED board and a spacer by fitting a cover to a LED so as to form a hollow space between a LED light emitting unit and a cover lighting unit. CONSTITUTION: In an emitter using a LED 4 as a light source, an acrylic cover 3 is integrated with the LED 4 so as to form a hollow part 12 between an LED light emitting unit 4' and an acrylic cover lighting unit 14. With this structure, since the irregular reflection of the light emitted from the LED 4 is generated in the hollow part 12, the lighting light at an area larger than a light source can be obtained. Lighting area can be freely set and the luminance of the lighting light can be uniformed by forming thickness of the cover 3 at minimum in the thickness l1 , l2 , l3 in the periphery of the hollow part 12 and fixing the LED 4 to the cover 3 having the arbitrary lighting area.  A female side connector, a board of LED, a resistor and a spacer or the like can be eliminated by providing a counterbore 10 at a leg part of the LED 4 so as to match with the shape of a male side connector.

Filed: 1979-06-28
Abstract: PURPOSE: To make the charge distribution on a photosensitive drum surface even, remove uneven electric potentials and achieve beautiful copying by forming the end edge of a shield plate opposing to a photoreceptor in arc form.  
     CONSTITUTION: A photosensitive drum 1 is rotated in the direction of an arrow and the photosensitive drum 1 is charged by the corona discharge generated by a discharge member 2. The central part of the photosensitive drum 1 becomes higher in electric potential than at the end part. Thereupon, the end 4 of the shield plate 3 opposing to the photosensitive drum 1 is formed in such arc form which is close to the photosensitive drum surface at the center and leaves from the photosensitive drum at both ends so that the photosensitive drum surface assumes an even charge distribution. As a result of this, the width W on the photosensitive drum surface charged by the discharge member 2 is relatively narrow in the central section of the shield plate but said charge width W' becomes much wider in the section at both ends of the shield plate 3, thus the two ends of the photosensitive drum 1 become higher in charge quantity than the central part and the electric potential at the end parts and the potential in the central part become even in terms of potential.
