PURPOSE: A wooden pattern processing machine minimizing transfer faulty due to the deformation of gantry is provided to, while minimizing the load actuating on gantry, exchange tool in the wooden pattern processing machine easily, and to reduce the power loss. CONSTITUTION: The wooden pattern processing machine includes: a horizontal plate(110) in which work table(113) is included; a base(100) which is set with a vertical block(130) included in the vertical direction upper side of both ends and has ruler shape; and an assembling structure of the gantry(300) which is installed to be supported in the upper of the base. ATC(400) is connected to one side of the base to prevent the interference due to the movement of gantry. The ATC is installed in the mount space(135) formed in the one side of inner side of vertical block of the base and is formed of rotary type tool unit in which a plurality of tools are installed as the rotation method. The rotary type tool unit is formed with a first rotational plate which includes a plurality of first elasticity blocks which are separable to columnar direction and a first driving unit which rotates the first rotational plate. The rotary type tool unit is installed inside of the first casing having a first open part(412). The first open part is included of the configuration where the first cover member which is connected to cylinder canning be opened and closed is more connected.
