To provide a linear drive mechanism comprising two linear drive means for reducing reaction on the slide of each of the linear drive means due to the contraction/elongation of a dust-proofing cover in a bellows structure.
The linear drive mechanism comprises the linear drive means 1 having the slide 10 to be driven along a guide 11 in the horizontal direction, and the linear drive means 2 having the slide 20 to be driven along a guide 21 in the vertical direction. On the side where the moving-direction lines of the slides 10, 20 to be moved cross each other, the common dust-proofing cover 3 in the bellows structure is provided for covering the guides 11, 21. The dust-proofing cover 3 is mounted at one end on the slide 10 which is moved in the horizontal direction, and at the other end on the slide 20 which is moved in the vertical direction. Even when the slide 10 is driven in the direction of contracting the bellows structure of the dust-proofing cover 3, the bellows structure is contracted in the vertical direction, therefore reducing reaction due to the contraction of the bellows structure to reduce force on the slide 10.
