As described above, in the cutting machine disclosed in Patent Document 1, the housing device and the cutting device are arranged side by side, so the size is increased in the left and right direction. From the viewpoint of space saving, it is preferable that the size of the cutting machine is suppressed from increasing in the left-right direction.

The present invention has been made in view of this point, and an object thereof is to provide a cutting machine capable of suppressing an increase in size in the left-right direction.

A cutting machine according to the present invention includes a stocker, a case body, a gripping portion, and a gripping movement mechanism. The stocker has an accommodation portion in which the workpiece is accommodated. The case main body is formed with a storage area for a user to store a workpiece in the storage section, and an opening communicating with the storage area and opening in a predetermined opening direction is formed. The gripping part is arranged on the side opposite to the opening with respect to the stocker, and is capable of gripping the workpiece. The grip movement mechanism moves the grip portion toward the stocker.
