Next, the operation and effects of the embodiment having the above configuration will be explained.

Now, in this example, the base 1 of the plane machine has a mechanism that restricts the downward movement of the front table 3, which is adjusted by moving up and down to adjust the cutting margin for the workpiece, when the amount of displacement of the front table 3 reaches a predetermined value. A stopper 28 is provided to release the downward movement restriction.

Therefore, by rotating the handle 9, the height of the top surface 3a of the front table 3 can be moved up and down to easily adjust the cutting margin of the workpiece, and the workpiece is always displayed on the scale 13 with the stopper 28. In addition, when replacing the plane blade on the plane body 2, the downward movement restriction of the front table 3 by the stopper 28 is released, and the front table 3 is As a result of being able to move the blade downward to a position outside the adjustment range, the blade opening for the plane barrel 2 is enlarged, the amount of exposure of the plane body increases, and the job of replacing the plane blade is facilitated.

That is, in the present invention, the front and rear tables placed horizontally in order to place workpieces to be horizontally transferred to the front and rear sides of the planer barrel, which is rotatably supported on the base, are moved upwardly and downwardly relative to the base. In a planer machine that is supported so as to be able to move independently in a direction, the base is provided with a planer that is movably adjusted to increase or decrease the cutting margin for the workpiece, and when the displacement amount of the front table reaches a predetermined value. By attaching a stopper for regulating the downward movement of the machine so that the downward movement regulation can be canceled, it is possible to prevent erroneous operations in which the machining allowance of the workpiece exceeds the adjustment range.
In addition, when replacing the planer blade, the exposed amount of the planer blade can be increased to improve workability when replacing the planer blade, so it is an extremely practical idea as a planer board.
