    摘要： A printed circuit board drilling machine, with a well-designed outer shape, providing excellent operability and maintainability, which sequentially makes a number of holes in at least one printed circuit board, placed on a table 22 moved in an XY plane, by using a drill driven by a spindle motor 27. The machine has openable/closable doors 20 and 21 which is separated into an upper door and a lower door in a front portion. The upper door 20 opens upward, while the lower door 21 opens downward. The upper door 20 comprises transparent material. Upon maintenance, the doors 20 and 21 are opened, and the table 22 is moved inwardly. Thus, the distance from the outside of the machine to the spindle motor 27 and its peripheral parts can be reduced, and maintenance can be easily performed with respect to the spindle motor 27 and its peripheral parts.
