  • Patent number: 11022764
    Abstract: Laser hazard at disconnection can be prevented with a simple structure. A tubular connector exterior, and a block that is incorporated on one end side of the connector exterior and on which a light emission portion or a light incident portion is mounted toward the other end side are provided. The light emission portion or the light incident portion is mounted on the block so that the optical axis direction thereof is tilted relative to the longitudinal direction of the connector exterior. The light emission portion is a lens through which light output from a light transmission path is collimated and emitted. At least part of the collimated light emitted through the lens is incident on a light diffusion portion provided inside the connector exterior.

  • Patent number: 11024476
    Abstract: A push-button switch may include a housing, an operation unit, a lock lever unit, a transmission mechanism, a movement regulating portion, a contact mechanism, and a first biasing portion. The movement regulating portion enables movement of a lever body to a second position when an end of the operation unit on a housing portion side is positioned at an initial position, and disables movement of the lever body to the second position when the end of the operation unit on the housing portion side is positioned closer to an operation surface than the initial position in a movable direction. The first biasing portion biases the plunger from an operating position toward a return position.

  • Patent number: 11011325
    Abstract: A push button switch may include a housing, an operation unit, and, a lock lever unit. A lever body of the lock lever unit may have a locking portion capable of locking one end of a long jig in an extending direction. The housing may have a fulcrum projection that contacts an intermediate portion of the jig having the one end locked to a locking portion when the lever body is moved using the jig, and serves as a rotation fulcrum of the jig.

  • Publication number: 20210135708
    Abstract: It is possible to determine, with a simple configuration, that the connection direction of a cable is the reverse direction. A cable is connected for use between a transmission device and a reception device, and transmits data in one direction. A connection direction determination unit determines whether the connection direction is the reverse direction, on the basis of a result of voltage monitoring at a predetermined position on a power-supply line. When the connection direction is determined to be the reverse direction, the information transmission unit transmits information indicating that the connection direction is the reverse direction, to the transmission device or the reception device.

  • Patent number: 10910174
    Abstract: A push-button switch may include a housing, an operation unit, a lock lever unit, and a biasing portion. A lever support portion may be connected to the operation unit so as to be movable together with the operation unit when a lever body is positioned at a second position. The housing may have a deformation portion that, when the operation unit is pulled in an opening direction when the lever body is positioned at the second position, deforms the lever body so as to be capable of releasing the pressing to the lever body by a holding unit.

  • Patent number: 10629398
    Abstract: A switch device includes an actuation unit, a movable unit, a first base, and a second spring, which is a torsion coil spring that acts between the actuation unit and the movable unit. The movable unit is movable with respect to the base. The second spring applies a force to the actuation unit when the actuation unit is at a third position in a direction that is not parallel to a direction in which the torsion coil spring applies a force to the actuation unit when the actuation unit is at a fourth position.
