  • Patent number: 11827488
    Abstract: The rotation of a lifting and lowering plate 56 is controlled such that, in a case where the height of the sheet loaded in a manual feed tray 50 is maximum, a feed roller 51 abuts the sheet at a first abutment position at a first moving velocity slower than a second moving velocity at a position upstream in the movement direction of the feed roller 51 from the first abutment position, and, in a case where the height of the sheet loaded in the manual feed tray 50 is minimum, the feed roller 51 abuts the sheet at a second abutment position at a third moving velocity slower than the first moving velocity at the first abutment position.

  • Patent number: 11791193
    Abstract: A first sensor is disposed in such a way that optical axes of a light emitting element and a light receiving element thereof are parallel to a left-right direction. A second sensor is disposed in such a way that optical axes of a light emitting element and a light receiving element thereof are parallel to a front-rear direction. When a position of a wafer to be loaded on a loading portion is taught, a position of the loading portion or a teaching jig to be loaded on the loading portion in the front-rear direction is detected by the first sensor by moving a hand in the front-rear direction by a moving mechanism, and a position of the loading portion or the teaching jig in the left-right direction is detected by the second sensor by moving the hand in the left-right direction by the moving mechanism.

  • Patent number: 11719031
    Abstract: A window regulator includes a guide rail, a carrier plate, and a raising/lowering means to raise/lower the carrier plate along the guide rail. The carrier plate includes a front surface sliding member configured to slide on a front surface of a flange portion of the guide rail and a back surface sliding member configured to slide on a back surface of the flange portion. The back surface sliding member includes a contact portion coming into contact with the back surface and a base portion that presses the contact portion against the back surface by a restoring force of elastic deformation. The contact portion extends toward the back surface and is elastically deformed and bent on the end side to allow the flange portion to enter from a lateral side in an extending direction thereof when assembling the carrier plate to the guide rail.

  • Publication number: 20230166392
    Abstract: An industrial robot continuously and automatically executes a teaching step of learning a hand position that is the position of a hand when mounting a transported object to be placed in a predetermined position on a placing section, and a calibration step of correcting the hand position learned in the teaching step. In the calibration step, the hand is moved to the hand position identified in the teaching step, and a transported object for teaching placed in the predetermined position is mounted and taken out onto the hand. Thereafter, the hand is moved again to the hand position identified in the teaching step and the transported object for teaching is placed on the placing section. Afterward, the position of the transported object for teaching is detected by second sensors attached to the hand and the hand position is corrected based on the detection result by the second sensors.
