Abstract: A document conveying apparatus is provided with a document tray, a feeding member, and a discharge tray disposed below the document tray. The document tray includes an upper tray member, a lower tray member, a movable tray member movable in a width direction orthogonal to a feeding direction of a document, a tray cover disposed to cover an underside of the movable tray member, and a driving portion. The driving portion moves the upper tray member and the movable tray member integrally to a raised position and a lowered position. The movable tray member and the tray cover are configured to be moved integrally in the width direction between a first position in which the movable tray member supports the document together with the upper tray member and a second position in which the movable tray member is retracted from the first position into below the upper tray member.

Abstract: A photoelectric conversion device includes a light receiving unit and a plurality of pixel control units. A first pixel control unit controls a first exposure period in a first pixel among a plurality of pixels based on a first exposure control signal, generates a second exposure control signal by delaying the first exposure control signal, and outputs the second exposure control signal to a second pixel control unit. When the first exposure control signal is enabled, the second pixel control unit controls a second exposure period such that a start time of the second exposure period coincides with a start time of the first exposure period. When the second exposure control signal is enabled, the second pixel control unit controls the second exposure period such that the start time of the second exposure period is later than the start time of the first exposure period.

Abstract: A document conveying apparatus is provided with a document tray and a discharge tray disposed below the document tray. The document tray includes an upper tray member, a lower tray member, a movable tray member, and a driving portion configured to move the upper tray member and the movable tray member integrally to a raised position and a lowered position. The movable tray member is configured to be moved in a width direction between a first position and a second position in which the movable tray member is retracted into below the upper tray member. The document tray includes a shutter configured to cover a gap created between the upper tray member and the lower tray member. The gap is created by the upper tray member and the movable tray member being moved to the raised position and the movable tray member being moved to the second position.

Abstract: A ranging device including: a control unit controlling a light emission timing in a light emitting device divided into emitting regions and a start timing of time counting; a receiving unit divided into receiving regions corresponding one-to-one to the emitting regions; a latch unit generating a light reception time value indicating an elapsed time from the start of the time counting to incidence of light based on the time count value and light reception signals; and a calculation unit calculating a flight time of light based on the light reception time value. Light emission timings of the emitting regions are different from each other, and a time difference between two light emission timings is shorter than a measurement period in each receiving region. The calculation unit calculates the flight time based on the light reception time value and the time difference.

Abstract: A ranging device includes: a processing unit configured to operate in a first mode for outputting a signal based on incident light to a first number of photoelectric conversion elements among photoelectric conversion elements and configured to operate in a second mode for outputting a signal based on incident light to a second number of photoelectric conversion elements among the photoelectric conversion elements, the second number being different from the first number; and a time conversion unit configured to generate a signal indicating a time at which light is incident on a light receiving unit based on a time count value input from a time counting unit and a signal generated in the light receiving unit. Switching from the first mode to the second mode is performed in a period from the start of light emission to the next start of light emission of a light emitting device.
