Abstract

The linearly moving and rotating device includes a support portion that supports an operated member integrally provided with the article support portion, for rotation about the movable axis and for movement along the first direction, and a linearly movable member which is moved along the first direction by the actuator. The operated member is connected to the linearly movable member in a portion spaced apart from the movable axis as seen along a direction along the movable axis. The linearly moving and rotating device includes an operating state switching portion which can be switched to a linearly moving state for restricting rotation of the operated member about the movable axis and for allowing movement of the operated member along the first direction, and to a rotating state for allowing rotation of the operated member about the movable axis and for restricting movement of the operated member along the first direction.

First claim

1 . A linearly moving and rotating device for moving an article support portion for supporting an article along a straight first direction and for rotating the article support portion about a movable axis extending perpendicular to the first direction, the linearly moving and rotating device comprises:
an operated member which is integrally provided with the article support portion; a support portion that supports the operated member for rotation about the movable axis and that supports the operated member for movement along the first direction; and a linearly movable member which is moved along the first direction by an actuator, wherein the operated member is connected to the linearly movable member in a portion spaced apart from the movable axis as seen along a direction along the movable axis, and an operating state switching portion which can be switched to a linearly moving state for restricting rotation of the operated member about the movable axis and for allowing movement of the operated member along the first direction, and to a rotating state for allowing rotation of the operated member about the movable axis and for restricting movement of the operated member along the first direction.

2 . The linearly moving and rotating device as defined in claim 1 , wherein the actuator includes a screw shaft arranged such that a pivot axis thereof extends along the first direction, and a rotation motor for drivingly rotating the screw shaft about the pivot axis, and
wherein the linearly movable member is attached to the screw shaft so as to move along the first direction as the screw shaft is rotated.

3 . The linearly moving and rotating device as defined in claim 1 , further comprising:
a controller for controlling operations of the actuator and the operating state switching portion, and wherein the controller performs a linear movement actuation control for causing the article support portion to be moved along the first direction by placing the operating state switching portion in the linearly moving state and activating the actuator, and a rotation control for causing the article support portion to be rotated about the movable axis by placing the operating state switching portion in the rotating state and activating the actuator.
