    Abstract: A backpack work apparatus comprises a back carrier frame; a drive motor mounted on the back carrier frame; a work tool driven by the drive motor; a right and left shoulder straps; a chest strap linking the intermediate points of the right and left shoulder straps; and an emergency release buckle device provided at the point where the chest strap is coupled to the intermediate point of the left shoulder strap, which is divided by the buckle device into two parts, an upper strap and a lower strap. The buckle device normally buckles the chest strap, the upper strap and the lower strap, and is capable of releasing the lower strap and the chest strap from the upper strap via a one part motion in an emergency.

    Abstract: An autonomous cleaning device (1), such as a robotic vacuum (1), has an optical sensor (50) that includes: a rotary body (51) configured to rotate relative to a main body (2) about a rotational axis (CX); a light-emitting device (61) provided on the rotary body; a light-receiving device (62) provided on the rotary body; a cover (52) disposed upward of the rotary body; and legs (70) disposed around the rotary body and supporting the cover. In a cross section orthogonal to the rotational axis, at least a portion of a surface of each of the legs is inclined with respect to a virtual radial line (RL) extending in the radial direction of the rotational axis.

    Abstract: A backpack work machine is provided and may include a backpack frame, a motor mounted on the backpack frame, a driven device driven by the motor, and an arm provided at a lower portion of the backpack frame. The arm is rotatable around an axis line that extends in a left-right direction of the backpack frame and has in a fore end portion thereof a throttle lever regulating output of the motor. The backpack frame also has in the lower portion thereof a support axis having an axis line, and the arm is supported by the support axis so as to be rotatable around the axis line of the support axis within a rotation range that extends between an up-down direction of the backpack frame and a front-rear direction of the backpack frame.
