Abstract: A sheet supply apparatus includes a tray on which a sheet is to be placed, a regulation guide, a supporting body, and a rotating body. The regulation guide is disposed to the tray and regulates a side end of the sheet in a width direction when the sheet is conveyed in a conveyance direction. The supporting body includes a first teeth part and moves in the width direction together with the regulation guide. The rotating body includes a second teeth part engaging with the first teeth part of the supporting body and rotates with movement of the supporting body. The second teeth part is displaced to the rotating body based on a position of the regulation guide.

Abstract: A drive transmission device includes a chassis fixed to an apparatus main body and a driving roller that is driven by a driving source. A belt member transmits rotational force of the driving roller. A tension roller contacts the belt member to apply tension to the belt member. A support member supports the tension roller rotatably and is swingable about a rotational shaft of the chassis. A screw fixes the support member to the chassis at a predetermined position. A retaining member is able to be engaged with the chassis, in which the support member is arranged and fixed between a part of the retaining member and the chassis in an insertion direction of the screw.

Abstract: In a printing apparatus, a platen configured to support a sheet to be printed includes an ink receiver configured to receive ink discharged from a print head. The ink receiver includes a plurality of first ink grooves and a plurality of second ink grooves configured to guide the received ink, the second ink grooves having a tilt angle greater than that of the first ink grooves. The platen includes an absorber configured to absorb the ink received by the ink receiver, the absorber being arranged on a back side of the ink receiver.

Abstract: An object of the invention is to provide a personal mobility that is able to turn by movement of the gravitational center of a passenger, without individually controlling each motor that drives the left and right wheels, and without using any special parts. The personal transporter includes left and right driving wheels (21) as front wheels, left and right casters (22) as rear wheels, and two motors (31) for independently driving the left and right driving wheels (21). By giving a camber angle, in which an upper part inclines inward when viewed from the front, with respect to the left and right casters (22), the torque or the applied voltage of the two motors (31) is the same, the caster (22) rotates in the direction of movement of gravitational center to act as a steering wheel, and it is possible to turn a personal transporter in the movement direction of the gravitational center.

Abstract: Provided is a sheet conveying apparatus that includes a conveying unit capable of changing its posture through rotation, and forms a sheet conveyance path capable of conveying a sheet without fail regardless of which posture the conveying unit is in. A first conveying unit is capable of being in a first posture and in a second posture by rotating from the first posture. In a case where the first conveying unit is in the first posture, a sheet conveyance path is formed in which the first conveyance path, the second conveyance path, and the third conveyance path are connected in this order. In a case where the first conveying unit is in the second posture, a sheet conveyance path is formed in which the first conveyance path and the third conveyance path are connected in this order.
