    Abstract: There are provided a blade drive device and an optical instrument. The blade drive device includes a substrate that has an opening, a front curtain and a rear curtain that are movable along an opening surface of the opening so as to open and close the opening, a front curtain locking portion that interlocks with opening and closing operations of the front curtain, a rear curtain locking portion that interlocks with opening and closing operations of the rear curtain, a regulation lever that is configured to be pivotally movable around a lever axis, that enters an operation trajectory of the front curtain locking portion and the rear curtain locking portion, and that is capable of entry and escape between an entry position for regulating the movement of the front curtain and the rear curtain in a closing direction and an escape position escaped from the operation trajectory, a regulation electromagnetic actuator that is configured to be rotatable around a regulation axis, and a linkage lever that causes the regulation lever to pivot around the lever axis in response to the rotation around the regulation axis of the regulation electromagnetic actuator. The regulation lever and the linkage lever engage with each other while being provided with play in a circumferential direction around the regulation axis.

    Abstract: In one embodiment of an enclosure device, a camera casing and light source casing are secured to a plate frame, and the enclosure device is configured to be mounted to an arm, such as a robotic welding arm. A shutter mounting arm may also be secured to the plate frame. A flap may be pivotally mounted to the distal end of the shutter mounting arm, such that the flap may be actuated between a first and second position by an actuator cooperatively engaged with the flap. The first position may be defined as to protect a camera lens positioned in the camera casing and a light source lens positioned in the light source casing. The second position may be defined as to not obscure a line-of-sight from either the light source and/or the camera to the work piece on the arm. A light source casing may be sandwiched between two side plates that are generally configured as mirror images of one another. The light source casing housing a light source may be configured as a laser designed to measure distances.

    Abstract: An apparatus including a camera shutter having a shutter window therethrough; a shutter drive connected to the camera shutter; and an aperture member having an aperture therethrough. The shutter drive includes at least one magnet and at least one coil. The shutter drive is configured to move the camera shutter when the coil is activated. The shutter window is sized and shaped to be moved into registry with the aperture. The shutter window is substantially at least as large as the aperture.
