[0045]

As described above, according to the present invention, the rotary axis of the cutter block for cutting the material to be cut is set to be substantially vertical and the upper part of the conveying path for the material to be cut is opened. Since it is not affected by the weight of the cutting material,
It is also possible to perform cutting of a material having a cutting surface longer than the length of the cutter block with high processing accuracy. Further, when the height of the cutter block is made higher than the height of the surface plate and the upper surface of the surface plate is a horizontal surface, the end surface processing of the wide material can be easily performed. Furthermore, by providing the auxiliary surface plate detachably, when the auxiliary surface plate is mounted above the surface plate, the material to be cut can be reliably transported, and the auxiliary surface plate can be mounted on the surface plate. When it is mounted on the side of the machine, the material to be cut can be transported in a more stable state when processing the end surface of wide material, which in turn can improve the processing accuracy and downsize the entire automatic planer machine. It is possible to achieve the above, and it is possible to provide the automatic planer with versatility.
