  • Patent number: 11052010
    Abstract: A training device suppresses unintended operation of an operation rod when executing an operation mode in which operation of the operation rod is controlled based on a force applied to the operation rod. The training device includes the operation rod, a motor, a force detector, a rotation information output sensor, a first command calculator, and a force corrector. The operation rod moves a limb. The motor operates the operation rod in a direction of degree of freedom. The force detector detects a force component and outputs a force component signal. The rotation information output sensor detects an operation position of the operation rod in a corresponding direction of degree of freedom. The force corrector calculates a corrected force component value based on operation positions of the operation rod and force component signal. The first command calculator calculates a first motor control command based on the corrected force component value.

  • Patent number: 9833374
    Abstract: A training apparatus includes a fixed frame, a training rod, a motor, rotation information detection sensor, tilt angle and position difference calculation units, determination, motor drive and position difference eliminating units. The training rod is supported by the fixed frame in a manner capable of being tilted by a motor about at least an X-axis or a Y-axis so as to hold the limb. The tilt angle calculation unit calculates a tilt angle of the training rod. The position difference calculation unit calculates a position difference. The determination unit obtains the position difference every time when a second time period elapses. If the position difference generated in the second time period is a first threshold or lower, the motor drive unit drives the motor so that the position difference is accumulated and maintained. The position difference eliminating unit resets the position difference at a predetermined timing.

  • Patent number: 8654411
    Abstract: An image scanning device accepts an instruction to scan a double-sided document and scans a plurality of double-sided documents with respect to each page to produce image data. Image data is eliminated when a page is determined as being solid colored from the image data produced by the scanning section. Image data other than the eliminated image data is transmitted to the outside. When an instruction to scan a double-sided document is received from the outside and accepted, elimination of image data is prohibited.

  • Patent number: 8593652
    Abstract: An image reader includes a path switching part, located at a branch point that switches between a double-sided path and a single-sided path. The double-sided path defines a conveyance route that passes through a reading position from the branch point to enter a conveyance path that causes a document to make a U-turn, and then again passes through the reading position to be discharged to a paper discharge tray. The single-sided path defines a conveyance route that, without passing through the reading position, merges into the conveyance path from the branch point. Along the double-sided path, document detecting sensors provide detection results so that a collision determination part determines a possibility of a collision between documents, and if such a possibility is determined, the path switching part switches the double-sided path to the single-sided path to prevent the documents from colliding head-on with each other in the vicinity of the reading position.

  • Patent number: 8582184
    Abstract: An image reader and document conveying method shorten times necessary for a discharge process that discharges a document in being conveyed and for an idle feeding process of a document that is left on a paper feed tray. If during double-sided reading, a stop key is operated to issue an instruction to cancel reading, a conveyance controller outputs a path specifying signal to select a single-sided path, and thereby a conveyance route is switched from a double-sided path to the single-sided path. For this reason, the discharge process that discharges a document being conveyed at the time of the reading cancellation to a paper discharge tray, and the idle feeding process that discharges a document left on a paper feed tray to the paper discharge tray are performed with use of the single-sided path that is shorter than the double-sided path, and therefore the times necessary for the discharge and idle feeding processes can be shortened.

The document detecting units are at least two in number and arranged to detect a document at different positions on a transportation route. The supply timing adjusting unit is arranged to measure a transportation distance of the document after detection by the document detecting units and to generate a supply signal. The document supplying unit is arranged to supply a document from a paper feed tray based on the supply signal. The supply timing adjusting unit is arranged to generate the supply signal based on a result of detection by the document detecting unit that corresponds to the specified scanning method.

  • Patent number: 8056896
    Abstract: In an image scanning apparatus, documents on a document tray are transferred one by one, and an upper surface height of the documents is lowered to turn off a height detection sensor. Different kinds of control modes are performed according to a document scanning mode. In an image-quality-priority scanning mode, a transfer unit suspends transfer of the document, the document tray is elevated until the upper surface height reaches a target height that is higher by a predetermined distance after the height detection sensor is turned on, and the transfer unit resumes the transfer of the document. In a speed-priority scanning mode, while the transfer of the document is continued by the transfer unit, the document tray is elevated until the document tray reaches the target height.
