Patent number: 11882248Abstract: 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.Type: GrantFiled: September 30, 2022Date of Patent: January 23, 2024Assignee: Ricoh Company, Ltd.Inventors: Masahiro Ishida, Shogo Nakamoto, Takuya Okamoto, Hiroki Hamashoji
