  • Publication number: 20190238700
    Abstract: An image reading device includes: a supply tray including a movable plate which moves from a first position to a second position according to a decrease in the number of sheet to be supported by a supply tray; a discharge guide including a discharge opening for discharging the sheet conveyed by a conveyance guide to a discharge tray, and moves from a third position to a fourth position according to the decrease in the number of the sheets to be supported by the supply tray; a first drive source and a first drive train that transmits a drive force from the first drive source to a discharge roller. The discharge roller discharges a sheet through a discharge opening by receiving the drive force from the first drive source.

  • Publication number: 20190068823
    Abstract: An image reading apparatus, having a housing, a feed tray, and a reader sensor, is provided. The housing includes a reversing guide, a discharge tray, and an opening. The reversing guide is configured to reverse a first face and a second face of a sheet and guide the sheet from a first position toward a second position in a direction from a rear side toward a front side at the first position and in a direction from the front side toward, the rear side at the second position. The discharge tray is arranged at a position lower than the reversing guide and is configured to support the sheet discharged from the conveyer path. The opening is formed between the reversing guide and the discharge tray and is configured to expose the sheet supported by the discharge tray so that the sheet is removed through the front side of the housing.

  • Publication number: 20170309728
    Abstract: In a process of implanting ions of an n-type impurity for threshold control into a semiconductor substrate surrounded by an element isolation portion, a resist pattern is formed such that the resist pattern covers a divot formed at a boundary portion of the element isolation portion with an SOI layer. Thus, since ions of the n-type impurity are not implanted into the divot, an etching rate of the divot in a cleaning process or the like is not accelerated, and etching can be suppressed. As a result, a BOX layer is prevented from becoming thin, so that degradation of a TDDB characteristic of the BOX layer can be prevented.

  • Patent number: 9783386
    Abstract: A sheet conveying apparatus includes: a conveyor configured to convey a sheet along a conveyance path; and a discharge tray having a support surface for supporting the sheet discharged from the conveyor. The conveyor includes a discharge unit for discharging the sheet conveyed along the conveyance path, onto the discharge tray. The discharge tray is provided with a projection protruding upward from the support surface and elongated in a direction along a discharge direction in which the sheet is conveyed. At least a portion of the projection which has a downstream edge of the projection in the discharge direction is a movable portion changeable between a first position at which an upper end portion of the projection is farthest from the support surface and a second position which is nearer to the support surface than the first position.

  • Patent number: 8792146
    Abstract: An image reading apparatus may include a cable for connecting one device or component to a controller configured to perform functions and execute instructions. To prevent breakage and stress on the cable, the cable may be fixed to a guide component. For example, the cable may be fixed to the guide component on a first side and be held by the component such that the cable includes a generally U-shaped slacked portion. According to one or more arrangements, the guide component may include an escape portion that allows for the movement of an openable unit of the image reading apparatus. In yet other aspects, the guide component may be attachable/detachable from a main body of the image reading apparatus.
