  • Patent number: 10674031
    Abstract: A driving device is used in an image reading apparatus, and reciprocates a scanning unit for reading an image on an original. The driving device comprises a pull member, a driving pulley which transmits driving force to the pull member, a following pulley which applies tension to the pull member and a pulley holder having a pulley axis which holds the following pulley rotatably. Then, the pulley axis has a lock pawl capable of locking an upper end portion of the following pulley and canceling engagement with the following pulley by being tilted toward a side of an axial center by elastic deformation. Furthermore, the lock pawl is arranged at a side of a tension acting direction from the pull member to the following pulley except the farthest position from the driving pulley among positions in a circumferential direction of the pulley axis. It is possible to attach and detach the following pulley easily at a time of maintenance or the like.

  • Publication number: 20200149625
    Abstract: In a shift device, a lever is able to slide in a front-rear direction relative to a housing, and an FFC electrically connects a sensor substrate of the housing to an operating substrate of the lever. Here, the lever is moved slidingly in the front-rear direction, which is on a perpendicular direction side relative to a width direction of the FFC. Because of this, a reduction in the durability of the FFC can be inhibited.

  • Publication number: 20200149634
    Abstract: In a shift device, as a result of lower sliding projections of a lever moving slidingly against lower sliding plates of soft materials, the slidability of the lever is improved. Moreover, as a result of restricting projections of the lever being abutted against stoppers of the soft materials, noise generated when a sliding motion of the lever is restricted is reduced. Additionally, because the lower sliding plates and the stoppers are formed integrally with each other, the structure can be simplified.

  • Publication number: 20200149627
    Abstract: At a shift lever device, at a time when a lever is rotated in a left-right direction, a joint of the lever moves a joint tube of a link in an up-down direction. Moreover, at a time when the lever is rotated in a front-rear direction, a link operating portion of the lever rotates an operation tube of the link in the front-rear direction around the joint side. Here, at the time when the lever is rotated in the left-right direction, the joint is moved in the left-right direction with respect to the joint tube. Therefore, the need to provide parts between the lever and the joint can be eliminated, and a number of parts can be reduced.

  • Publication number: 20200128148
    Abstract: A document reading device includes red, green, and blue photoelectric transducers; a reader that reads a color image of a document with the photoelectric transducers; and a converter that converts the read color image into a grayscale image. The converter determines the maximum tone value MAX(RGB) among the red, green, and blue tone values of the RGB signal (RGB) of the pixel of the red, green, and blue colors to be a grayscale value of the pixel.

  • Publication number: 20200059570
    Abstract: An image reading device includes an image reader that scans a document so as to read an image of the document. The image reader includes a scanning body in which at least plural mirrors, a condenser lens, and an image sensor are disposed. In the scanning body, concerning positional relationships among the plural mirrors as viewed from a main scanning direction, the plural mirrors are disposed on two sides with respect to an imaginary line extending along an optical axis of reflected light from the document. The mirrors on a corresponding one of the two sides are disposed such that a reflecting position of a mirror on a downstream side in a traveling direction of the reflected light is positioned closer to the document and also to the imaginary line than that of a mirror on an upstream side in the traveling direction of the reflected light.

  • Patent number: 10567609
    Abstract: An illumination device includes a light guide member having a bar-like shape and a light source disposed so as to face an end surface of the light guide member. The illumination device guides light from the light source in the light guide member and emits the light from a light emission surface of the light guide member formed in a longitudinal direction of the light guide member. The light emission surface includes a first light diffusing portion that is formed in a first portion near the light source and that has a protruding/recessed shape, and a second light diffusing portion that is formed in a second portion adjacent to an end of the first light diffusing portion, the end being away from the light source. The second light diffusing portion has a protruding/recessed shape and has lower light diffusivity than the first light diffusing portion.

  • Patent number: 10508732
    Abstract: In a shift lever device, a first facing cavity and a second facing cavity of a lever, and a first facing hole and a second facing hole of a printed wiring board, respectively face each other when the lever is disposed in an “H” position. Thus, in a state in which the lever is disposed in the “H” position when the shift lever device is being assembled, the first facing cavity and the second facing cavity respectively face the first facing hole and the second facing hole, thereby enabling the accuracy of relative assembly positions of a magnet of the lever and detection elements of the printed wiring board to be increased, and enabling the detection accuracy of a shift position of the lever to be improved.
