  • Patent number: 10524747
    Abstract: A holder (100) included in an X-ray imaging device holds an operation device for wirelessly operating the X-ray imaging device in a removable manner. The holder (100) sets the operation device unremovable when the X-ray imaging device is not in operation, and sets the operation device removable when the X-ray imaging device is in operation. This easily prevents the X-ray imaging device from being brought away.

  • Patent number: 10433806
    Abstract: An operation device (200) for wirelessly operating an X-ray imaging device (1) is held in a removable manner in a holder (100) included in the X-ray imaging device (1). The operation device (200) includes a control unit (211) that provides a notification when detecting that a predetermined condition is satisfied while the operation device (200) remains removed from the holder (100). This structure provides various notifications including a notification for preventing the operation device from being left or lost.

  • Publication number: 20180153499
    Abstract: An operation device (200) for remotely operating an X-ray imaging device (1) includes an operation unit (280), a grip detection unit (240), which determines whether an operation received by the operation unit (280) is a normal operation or an erroneous operation, and a control unit (230), which transmits an operation signal corresponding to the operation to the X-ray imaging device (1). The control unit (230) transmits the signal when the grip detection unit (240) determines that the operation is a normal operation. The operation device is prevented from causing an erroneous operation of its target device.

  • Patent number: 9156625
    Abstract: An object detecting actuator and an object detecting switch with increased durability. The actuator in one embodiment includes a roller that receives a load of an external force; and a roller lever to which the roller is rotatably attached by means of a rotary shaft, the actuator being a displacement member that is displaced in accordance with the load of the force received by the roller, wherein the roller is constituted by a sintered body of stainless steel material impregnated with lubricating oil, and a density of the sintered body of stainless steel material is in a range of 6.45 to 6.7 g/cm3.

  • Patent number: 8698069
    Abstract: A slit is formed in a plunger of a limit switch in such a manner that an amount of light incident on a light receiving element is changed in accordance with displacement of the plunger. The limit switch is provided with a setting processing unit (123) for setting a voltage value outputted from the light receiving element as a threshold value when a setting instruction is inputted in a state where the plunger is displaced to a designated position by a user, a position detecting unit (113) for performing detection processing of detecting whether or not the plunger is placed at a closer position to a reference position than to the designated position by comparing the set threshold value and the voltage value outputted from the light receiving element, and an output signal controlling unit (119) for outputting a signal based on a result of the detection processing.

  • Patent number: 6984797
    Abstract: A push-button switch has a plunger to be pressed so as to activate its main body supported by a base member. A cap serving as a pressing member is on an outer edge portion of the plunger. The outer periphery of the cap is surrounded by a frame part of a lens member made of a transparent resin material such that the light from a light source disposed near the center of the plunger is guided to the upper edge part of the frame part.
