Printing apparatus
A printing apparatus that is unlikely to damage a printing medium with a detection lever includes a feeding unit configured to receive a printing medium and to convey the printing medium in a conveyance direction; and a detection lever configured to rotate about a rotation axis for detecting a printing medium on the feeding unit, wherein in a width direction of a printing medium, which intersects with the conveyance direction, a first position of a contact between the detection lever and the printing medium and a second position of a center of the rotation axis are different.
DOCUMENT CONVEYING DEVICE
A document conveying device includes a sheet feeding tray, a sheet feeding mechanism, a sheet feeding tray lifting mechanism, a top plate, a fixed wall part, a lifting wall part, and a reflective optical sensor. The top plate is in contact with a lower surface of the document to be fed. The fixed wall part is provided extending downward from an upstream side end portion of the top plate, and is fixed in position. The lifting wall part is provided extending upward from a downstream side end portion of the sheet feeding tray, and lifted and lowered along the fixed wall part together with the sheet feeding tray. The reflective optical sensor detects the document placed on the sheet feeding tray. The reflective optical sensor emits light in a direction inclined downstream of the sheet feeding direction from a vertically upward direction.
PRINTING APPARATUS
A printing apparatus that is unlikely to damage a printing medium with a detection lever includes a feeding unit configured to receive a printing medium and to convey the printing medium in a conveyance direction; and a detection lever configured to rotate about a rotation axis for detecting a printing medium on the feeding unit, wherein in a width direction of a printing medium, which intersects with the conveyance direction, a first position of a contact between the detection lever and the printing medium and a second position of a center of the rotation axis are different.
Sheet separation device, sheet laminator, and image forming system
A sheet separation device includes a sheet separation unit, a displacement detector, a displacement adjuster, and a controller. The sheet separation unit performs a sheet separating operation and a sheet inserting operation. The displacement detector detects a displacement amount of the two-ply sheet when the two-ply sheet is displaced in a width direction of the two-ply sheet and detects a displacement amount of the inner sheet. The displacement adjuster adjusts the displacement of the two-ply sheet in the width direction before the sheet separating operation, based on the displacement amount of the two-ply sheet in the width direction detected by the displacement detector. The controller causes the displacement adjuster to adjust relative positions of the two-ply sheet and the inner sheet between the sheet separating operation and the sheet inserting operation, based on the displacement amount of the inner sheet in the width direction detected by the displacement detector.
Card issuing device
A card issuing device for using with a plurality of cards includes a card storage part which accommodates the plurality of cards, a card send-out mechanism which sends out a card among the plurality of cards from the card storage part, a card conveyance mechanism which conveys the card sent out by the card send-out mechanism toward a card discharge port along a card conveyance passage connected with the card discharge port, an optical sensor which is located on a lower side with respect to the card conveyance passage and reads a code indicated on a rear face of the card, and a dust adhesion prevention mechanism which prevents dust from adhering to a reading face of the optical sensor when the optical sensor is not used.
Medium feeding device and control method for medium feeding device
A medium feeding device includes a placement section on which a medium group is supported; a raising and lowering section configured to raise and lower the placement section; a pickup unit that includes a pickup roller that comes into contact with an upper section of the medium group and a support section that applies a downward force to the pickup roller, and that feeds a medium in order from a top in a feed direction while applying a downward pressing force to the medium group from the pickup roller; a control section; and a detection section configured to detect the pressing force, wherein the control section causes the raising and lowering section to raise and lower the placement section such that a detected pressing force falls within a target range.
