  • Patent number: 11882248
    Abstract: A reading device includes a carriage configured to move in a sub-scanning direction with reference to an object placed on a contact glass, an optical sensor attached to the carriage, the optical sensor being configured to scan the object placed on the contact glass to obtain an image of the object, and a reference scale used as a reference when a dimension of the object is computed based on the image obtained by the optical sensor. In the reading device, the reference scale extends in a main scanning direction and a sub-scanning direction with reference to the object, and is disposed outside a range of image acquisition in which the optical sensor scans the object to obtain the image of the object as the carriage moves and inside a maximum movement range in which the carriage is movable and the optical sensor obtains the image of the object.

  • Patent number: 11860564
    Abstract: A drive transmitter includes a first member and a second member. The first member includes an opening through which a rotary shaft passes, a wall orthogonal to an axial direction of the first member, and a drive transmitting portion by which a driving force is transmitted. The second member has a rigidity greater than the first member and is configured to be fastened to the first member. A space is between the second member and the first member, with the first member and the second member being overlaid in a fastening direction of the second member, prior to fastening of the first member and the second member. At least a part of the wall of the first member defining the space with the second member is configured to shift toward the second member to reduce a diameter of at least a part of the opening at the fastening.

  • Publication number: 20230375967
    Abstract: A fixing device includes an endless fixing rotator, a slide aid, a pressure rotator, a nip formation plate, a support, a heat source, and a reflector. The endless fixing rotator has flexibility. An inner circumferential surface of the fixing rotator slides over the slide aid. The pressure rotator contacts an outer circumferential surface of the fixing rotator. The nip formation plate is disposed inside the fixing rotator to contact the pressure rotator via the fixing rotator and the slide aid to form a nip between the fixing rotator and the pressure rotator. The nip formation plate has a thermal conductivity equal to or greater than 10 W/mK. The support supports the nip formation plate. The heat source is disposed inside the fixing rotator to heat the fixing rotator. The reflector reflects radiant heat from the heat source.
