SOLUTION: A drilling device for a printed board performs sequential drilling of many holes using a drill driven by a spindle motor in at least one printed board loaded on a table 22 moved or controlled in XY plane. On the front surface of this device, doors 20, 21 divided into an upper portion and a lower portion are provided, the upper door 20 being operable upward and the lower door 21 downward. The upper door 20 is constituted with transparent material. In maintenance, by opening the doors 20, 21 and by moving a table 22 on the depth side, distance from the outside of the device to its circumference containing the spindle motor can be shortened, and maintenance of the circumference containing the spindle motor can easily be performed.</p> |
