Patent number: 6118514Abstract: In an image forming apparatus, an exposure head has blue light emitting elements, a base on which the blue light emitting elements are provided, bonding pads formed on the base, and an aluminum-made reflecting layer formed on each bonding pad. Each aluminum-made reflecting layer has a reflectivity of 90% or higher to blue light from the light emitting element with respect to the regular reflection component. Part of blue light generated by one of the light emitting elements may travel to an adhered surface of the light emitting element, but it is reflected by the aluminum-made reflecting layer without being absorbed by the adjacent bonding pad, so that that part of blue light is re-directed toward a microcapsule recording sheet.Type: GrantFiled: September 17, 1998Date of Patent: September 12, 2000Assignee: Brother Kogyo Kabushiki KaishaInventor: Takeo Iwasaki

Patent number: 5787324Abstract: Maintenance performance is promoted and a vivid printed image is provided in an electrophotographic device capable of conducting color printing. Cartridges corresponding to different printing colors, each of which includes a photosensitive body, are stacked in a vertical direction. A recording sheet is fed along a sheet feeding path and brought into contact with the photosensitive bodies corresponding to the respective colors, and toner images of the respective printing colors are transferred on the recording sheet. A transfer belt for feeding the recording sheet is arranged in a front cover, and the transfer belt is exposed when the front cover is opened. Therefore, correcting a mis-feeding of the recording sheet is facilitated. Also, the respective cartridges are spaced apart such that optical paths are provided between the cartridges so that optical beams corresponding to the respective printing colors may be directly irradiated onto the corresponding photosensitive bodies.Type: GrantFiled: September 24, 1996Date of Patent: July 28, 1998Assignee: Brother Kogyo Kabushiki KaishaInventor: Takeo Iwasaki

Patent number: 5701191Abstract: The housing 2 is integrally formed with a cylindrical support portion 6. A cylindrical bore 30a is formed through the support portion 6. An inner diameter of the bore 30a is made substantially equal to an outer diameter of the semiconductor laser 4. The semiconductor laser 4 is therefore supported in the bore 30a. A lens barrel 7 holds therein a collimator lens 5. The outer diameter of the lens barrel 7 is also substantially equal to the inner diameter of the bore 30a. The lens barrel 7 is also supported in the bore 30a.Type: GrantFiled: April 22, 1996Date of Patent: December 23, 1997Assignee: Brother Kogyo Kabushiki KaishaInventor: Takeo Iwasaki

Patent number: 5317444Abstract: An optical scanning apparatus of the present invention is for optically scanning a medium. In the optical scanning apparatus, a light source receives image information and emits light beam modulated in accordance with the image information. A single optically imaging system is positioned in a single location for receiving the light beam from the light source and for focusing the light beam to be focused on the medium. A reflective mirror formed with a single reflective surface is provided for reflecting the light beam from the optically imaging system to direct the light beam to the medium. The reflective mirror is rotated by a motor at a fixed speed to allow the reflective surface to scan the light beam on the medium in a scanning sweep. Surfaces other than the reflective surface of the reflective mirror is prevented from directing the light beam to be focused on the medium.Type: GrantFiled: November 30, 1992Date of Patent: May 31, 1994Assignee: Brother Kogyo Kabushiki KaishaInventor: Takeo Iwasaki
