Patent number: 11102369Abstract: An image reading device includes (i) light guides extending in a main scanning direction and configured to emit light from a light source toward a reading target moving relatively in a sub-scanning direction, the light from the light source being projected into end surfaces of the light guides in the main scanning direction, (ii) an optical filter arranged between the light source and the end surfaces of the light guides and configured to block or attenuate light having a specific wavelength from the light from the light source, (iii) a lens body to focus reflected light reflected by the reading target onto a light receiver to convert the reflected light into an electrical signal, and (iv) a lens holder. The lens holder includes a first positioner for positioning the light guides and a second positioner for positioning the optical filter.Type: GrantFiled: September 4, 2019Date of Patent: August 24, 2021Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Hiroaki Matsunaga, Daisuke Ohama, Yuki Okuhigashi, Masahiko Takashina, Shigeru Matsuo, Masaki Wakisaka

Patent number: 10999456Abstract: An image reading device includes light guides (5, 6) that emit light to an object to be read, a lens body (8) that condenses reflected light, a light receiver (13) that receives the reflected light, a sensor board (24) on which is mounted the light receiver (13), a lens holder (11), and a housing (9) that houses or holds these components. The lens holder (11) includes a holder bottom (11g), light guide positioners (11a, 11b) and lens body holders (11e, 11f). In the lens holder (11), the lens body (8) is attached between the lens body holders (11e, 11f), the sensor board (24) is attached to the holder bottom (11g) such that the light receiver (13) aligns with an optical axis of the lens body (8), and the light guides (5, 6) are attached to the light guide positioners (11a, 11b). A surface of each light guide positioner (11a, 11b) that faces the corresponding light guide (5, 6) to be attached has at least a portion having a same shape a s a shape of a surface of the light guide.Type: GrantFiled: December 7, 2018Date of Patent: May 4, 2021Assignee: Mitsubishi Electric CorporationInventors: Daisuke Ohama, Hideki Kunishio, Masaaki Okada, Yuki Okuhigashi, Masahiko Takashina, Masaki Wakisaka
