Claims

[Claims for Utility Model Registration] (1) A belt support that supports from inside a toothed belt that reciprocates in a vertical direction to reciprocate a movable table, and a lifting engaging body that engages the toothed belt when rising. a pair of belt support and movement means arranged before and after the moving table, and a pair of rails corresponding to each of the belt support and movement means and spaced apart from each other and provided in a straight line; The elevating and lowering engaging body of the belt support and movement means, which is pressed and moved by the table, is pushed up by the rail corresponding to the belt support and movement means and engages with the toothed belt. A mechanism to prevent the toothed belt from deflecting. (2) The toothed belt deflection prevention mechanism according to claim 1, wherein the movable table and the pair of belt support and movement means have a guide rail that runs in common. (3) The toothed belt deflection prevention mechanism according to claim 1 or 2, wherein the separated portion of the pair of rails is located approximately at the center between the pair of pulleys meshing with the toothed belt. (4) The toothed belt deflection prevention mechanism according to any one of claims 1 to 3, wherein the belt support is a rotatable toothed pulley, and the elevating and lowering engaging body is a toothed pulley whose rotation is restricted.
