Claim:
1. An industrial robot comprising a horizontal multistage telescopic device, the horizontal multistage telescopic device including: a base including a slider support, the slider support including a slider receiver; a slider including a slider guide disposed below the slider, the slider guide being provided along a longitudinal direction of the slider, the slider guide being movably supported by the slider receiver to movably mount the slider to the base, the slider having a width dimension in a horizontal direction set to be larger than a width dimension of the base, the slider being mounted to the base so as to be movable in a first direction and in a second direction that are opposite to each other along the horizontal direction, the slider having a movement limitation position as a home position in the second direction, the slider being disposed above the base; an output arm having an end in the second direction, the end being provided with an output arm support, the output arm being expanded in the first direction from the output arm support, the output arm support being mounted to the slider so as to be horizontally movable in the first and second directions, the output arm having an end in the first direction to which an end effector, such as a hand, is mounted, the output arm being provided above the slider; a movement mechanism including a first rotor and a second rotor mounted to the ends in the first and second directions, respectively, of the slider, and a linear member mounted across the first and second rotors, the linear member having a first part connected to the base and a second part connected to the output arm support, the second part being opposite to the first part in order to move the output arm in the first direction with the movement of the slider by a distance corresponding to at least a stroke of movement of the slider; a motor mounted to an end of the slider in the second direction, the motor being provided spaced apart upward from an upper surface of the slider so as not to interfere with a movement region of the output arm; and a rotation transmitting member for transmitting torque of the motor to the second rotor of the movement mechanism, the rotation transmitting member being configured by a rotation transmission mechanism including a driving rotor mounted to a rotary shaft of the motor, a driven rotor provided so as to coaxially and integrally rotate with the second rotor, and a transmission linear member mounted across the driving rotor and the driven rotor.
