Description

  The present invention relates to a numerical control device, and more particularly to a numerical control device having a common printed circuit board.

As a control board for controlling the device, a dedicated board is generally prepared according to the specifications. On the other hand, in order to avoid preparing a dedicated board, multiple types of standard divided boards are prepared, and they are combined with spacers between the divided boards according to the required specifications. A technique has been proposed in which the same specification as that of the dedicated substrate can be satisfied by fixing in a shape housing (see, for example, Patent Document 1).
Patent Document 1 discloses a structure in which a common substrate common to a plurality of devices to be controlled and an individual substrate according to the specifications of each device to be controlled are arranged on the same plane.

On the other hand, when a board with one standardized dimension and a board with another standardized dimension are connected by a connector in one plane, the connection body further matches the dimension of the other standardized board. A design method has been proposed (for example, see Patent Document 2).
Patent Document 2 discloses that when an additional slot is required for the first board as the main board, the second board having the slot can be added as an expansion board.
