  • Patent number: 10564584
    Abstract: A sheet-conveying device includes first, second, and third rotary members, and a switching unit. The first rotary member rotates in one direction to convey, with the second rotary member, a sheet in a first direction and to convey, with the third rotary member, the sheet in a second direction. The switching unit switch from a first to a second state by moving the first rotary member before a trailing end of the first direction conveyed sheet passes through the first and second rotary members. The first state is a state where the second rotary member contacts a first surface of the sheet and the first rotary member contacts a second surface of the sheet. The second state is a state where the first rotary member contacts with the first surface of the sheet and the third rotary member contacts the second surface of the sheet.

  • Patent number: 10556762
    Abstract: A sheet conveying apparatus includes first, second, and third rotating members, a switching unit, and a regulating member. The first rotating member rotates in one direction to convey, with the second rotating member, a sheet in a first direction and convey, with the third rotating member, the sheet in a second direction different from the first direction. The switching unit switches the first rotating member between first and second positions. The first position is a position in which the first rotating member coveys a sheet with the second or third rotating member. The second position is a position to which the first rotating member is retracted from the first position. Where the first rotating member moves from the first position, the regulating member regulates the sheet position so that a sheet rear end held by the second and third rotating members is positioned above a first rotating member moving trajectory.

  • Patent number: 10435260
    Abstract: A sheet conveying apparatus includes a first rotating member, a second rotating member to convey a sheet in a first direction upon the first rotating member rotating, a third rotating member to convey the sheet in a second direction upon the first rotating member rotating, and a switching unit. The switching unit switches a position of the first rotating member between a first position at which the first and second or first and third rotating members convey the sheet, and a second position at which the first rotating member is retracted. Before a rear end of the sheet has been conveyed by the first rotating member and the second rotating member, the switching unit moves the first rotating member from the first position towards the second position. The switching unit stops a movement of the first rotating member at a position between the first position and the second position.

  • Publication number: 20190298225
    Abstract: A biological information measurement apparatus comprises: a spectrometer; a housing that contains the spectrometer and includes a surface on which a measurement target is to be placed, and an aperture portion through which light illuminating the measurement target placed on the surface and light reflected from the measurement target are to pass; and a shutter member that can move between a first position of opposing the aperture portion of the housing and a second position of retreating from the first position of opposing the aperture portion, the shutter member including a white reference surface. If the shutter member is at the first position, the spectrometer performs calibration using the white reference surface. If the shutter member is at the second position, the aperture portion and the measurement target oppose each other, and the spectrometer colorimetrically measures the measurement target.

  • Patent number: 10294068
    Abstract: An image forming apparatus includes a discharging portion to discharge a sheet on which the image has been formed, an image reading portion to read the image formed on the sheet, and a switching portion to switch between a first position where the discharged sheet is conveyed to a supporting portion and a second position where the discharged sheet is conveyed toward the image reading portion. The sheet conveyed toward the image reading portion is conveyed to a reading position after conveyance of the sheet by the discharging portion is finished, and the control portion conveys the sheet at a first conveyance speed in a period before a trailing end of the sheet is released from the discharging portion and conveys the sheet at a second conveyance speed different from the first conveyance speed in a period after the trailing end of the sheet is released from the discharging portion.

  • Publication number: 20190092593
    Abstract: A sheet conveying device includes a blocking member having a blocking surface with which a leading end of a sheet that is being conveyed comes into contact for obliquity correction. The blocking member is rotated by being pushed by the sheet against an urging force of a positioning unit that positions the blocking member to be in the standby position. The blocking member is rotatable to be in a sheet-passage-allowing orientation in which the sheet is allowed to pass. When a trailing end of the sheet that is being conveyed has passed the blocking member, the blocking member that is in the sheet-passage-allowing orientation rotates in a same direction as a sheet conveyance direction and is positioned to be in a standby position.

  • Patent number: 10189674
    Abstract: An image forming apparatus including an image forming unit, first and second discharging portions, first and second supporting portions, an image reading portion, and first and second switching portions is provided. The first switching portion switches between causing a sheet bearing an image formed by the image forming unit to be discharged to the first supporting portion by the first discharging portion and causing the sheet to be conveyed toward the image reading portion that reads the image. The second switching portion switches between causing the sheet whose image has been read to be conveyed toward the second discharging portion that discharges the sheet whose image has been read to the second supporting portion and causing the sheet to be conveyed toward the image forming unit. The image reading portion is disposed above the first discharging portion and further on the inside of the apparatus than the second switching portion.

  • Patent number: 10046945
    Abstract: An image forming system includes an image forming apparatus, an image reading apparatus, and a connecting conveyance path that branches from a second main conveyance path of the image reading apparatus and joins a first sub conveyance path of the image forming apparatus, and is configured to convey an original from the image reading apparatus to the image forming apparatus. The system controls conveyance of the original so that a first side becomes a side that faces an image forming unit if the first side of the original is designated as the image formation side or so that a second side becomes the side that faces the image forming unit if the second side of the original is designated as the image formation side.
