Patent number: 7564600Abstract: The image reading apparatus of this invention moves the discharge guide to lead documents after passing the contact glass to the discharge tray in order to cope with different functions to improve image reading accuracy demanded for the image reading and to increase stacking capacity of the discharge tray easily. The image reading accuracy is improved when the width of documents to contact the contact glass surface is made wide by making the tilt angle of the discharge guide small to get the documents parallel to the contact glass surface. The stacking capacity of the discharge tray increases when the tilt angle of the discharge guide is made large.Type: GrantFiled: March 5, 2004Date of Patent: July 21, 2009Assignees: Kabushiki Kaisha Toshiba, Toshiba Tec Kabushiki KaishaInventor: Naoki Shoji

Patent number: 7361874Abstract: An auto focusing mechanism is provided in a surveying instrument, such as an electronic level, that is capable of automatically focusing a telescope on a sighted staff. As a focusing lens (21b) is moved by a motor (41) along the optical axis of a telescope (20), the image of a staff (1) sighted by the telescope (20) is converted into an electrical signal by a line sensor (24). The output signal of the line sensor (24) is converted into a digital signal by an A/D converter (27) and stored in a RAM (28). Based on the data stored in the RAM (28), a microcomputer (3) monitors frequencies of the component signals, or wavelets, contained in the output signal of the line sensor (24) stored in the RAM (28). When a particular frequency of the output signal associated with the position of the focusing lens (21b) is detected a determination is made that the focusing lens (21b) is located at a focusing position, and the distance from the telescope (20) to the staff (1) is calculated.Type: GrantFiled: December 28, 2005Date of Patent: April 22, 2008Assignee: Sokkia Co., Ltd.Inventors: Nobuyuki Nishita, Naoki Shoji, Takashi Nagao
