  • Patent number: 11487234
    Abstract: A sheet accommodating apparatus includes an apparatus body, a first cassette to be drawn out in a draw-out direction with respect to the apparatus body, a second cassette disposed adjacent to the first cassette in a vertical direction, a holder member attached to the apparatus body, and a first light emitting member and a second light emitting member that are supported by the holder member. The first cassette includes a first accommodating container and a first cover. The second cassette includes a second accommodating container and a second cover. The first cover has a first hole in a position opposing the first light emitting member such that the light emitted from the first light emitting member passes therethrough. The second cover has a second hole provided in a position opposing the second light emitting member such that the light emitted from the second light emitting member passes therethrough.

  • Patent number: 11360425
    Abstract: An image forming apparatus includes a cassette, an image forming unit configured to form an image on a sheet fed from the cassette a set position, a guide rail configured to draw out the cassette from the set position, and a movable stopper unit that regulates a movement of the cassette in a draw-out direction by abutting with the cassette while the cassette is drawn out from the set position along the guide rail. The movable stopper unit includes a regulating portion movable between a regulating position where the regulating portion regulates a movement of the cassette within a moving trajectory of the cassette in moving in the draw-out direction and a retracting position where the regulating portion is located outside of the moving trajectory and does not regulate the movement of the cassette, and an urging portion configured to urge the regulating portion to the regulating position.

  • Publication number: 20210382429
    Abstract: A sheet accommodating apparatus includes a first cassette provided so as to be drawn out in a draw-out direction, a second cassette disposed adjacent to the first cassette in a vertical direction, one holder member, and a first light emitting member and a second light emitting member that are supported by the holder member. The first cassette includes a first accommodating container and a first cover. The second cassette includes a second accommodating container and a second cover. The first cover has a first hole provided in a position opposing the first light emitting member in the draw-out direction such that the light emitted from the first light emitting member passes therethrough. The second cover has a second hole provided in a position opposing the second light emitting member in the draw-out direction such that the light emitted from the second light emitting member passes therethrough.

  • Patent number: 10836594
    Abstract: A sheet feeding apparatus includes a sheet stacking unit on which a sheet is stacked, a feed member configured to abut against the sheet stacked on the sheet stacking unit to feed the sheet, a friction member disposed on the sheet stacking unit so as to be opposed to the feed member; a drive unit configured to drive the feed member, a detection unit configured to detect a load on the drive unit when the drive unit drives the feed member, and a control unit configured to control the drive unit. The control unit causes the drive unit to drive the feed member at a first speed and thereafter in a case where the load detected by the detection unit satisfies a predetermined condition, the control unit causes the drive unit to drive the feed member at a second speed higher than the first speed.

  • Publication number: 20200290832
    Abstract: An image forming apparatus includes a stacking unit, a pickup roller, a conveying roller, a transfer unit, a motor, a determiner, and a velocity adjuster. The conveying roller conveys, in a conveying direction, a sheet fed by the pickup roller from the stacking unit. The determiner determines a value of a parameter corresponding to a load torque applied to a motor rotor. Based on a length between a front end of the sheet and a nip position of the conveying roller at a first timing when the determined value changes from a value smaller than a predetermined value to a value greater than the predetermined value, and a length between the nip position and a predetermined position downstream of the conveying roller and upstream of an image forming position in the conveying direction, the velocity adjuster adjusts a conveying velocity at which the sheet is conveyed to the predetermined position.
