DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of claim 1 will be described below with reference to FIGS. 1 to 4 of the drawings.

A box 1 of this control device has a lower box 1 with an upper opening.
1 and an upper lid 12 with a lower opening are overlapped and connected by screws 13.

The lower box 11 is equipped with an input/output board 2 in a horizontal direction, and the input/output board 2 is fixed with screws 21. This input/output board 2 includes a first connector 22 with the insertion direction facing upward, an external connection terminal device 23 extending upward and exposed to the outside from the terminal portion 14 of the top cover 12, and an external connection terminal device 23 shown in FIG. Electronic components constituting input/output means 24 for transmitting and receiving control information to and from the terminal device 3 connected to the terminal device 3 are mounted on the top surface.

A central control board 4 is installed horizontally on the top lid 12, and is fixed with screws 41. This central control board 4 includes a second connector 42 that connects with the first connector 22 of the input/output board 2 with the insertion direction facing downward, and a third connector 43 with the insertion direction facing downward.
and a board fixing spacer 44 are provided on the lower surface, and furthermore, an electronic component 46 constituting the central control means 45 shown in FIG. 4 is provided on the upper surface. The electronic components 46 include an operation switch 47 and a display 48, which are exposed through an operation opening 15 and a display opening 16 formed on the upper surface of the upper lid 12.

Furthermore, a memory board 5 is disposed on the lower side of the central control board 4, that is, on the side of the input/output board 2, in a horizontal direction with respect to the central control board 4. A fourth connector 51 to be connected to the connector 43 is installed with the insertion direction facing upward, and this third connector 43
It is coupled to the central control board 4 by coupling with the board fixing spacer 44 and fixing the screw 52 to the board fixing spacer 44. This memory board 5
An electronic component 54 constituting a storage means 53 for storing programs and data as shown in FIG. 4 is installed on the bottom surface of the computer.

With this configuration, by removing the screws 13 and separating the lower box 11 and the upper cover 12, the connection between the first connector 22 and the second connector 42 is removed, and the memory board 5 and the central control The storage board can be separated into an upper lid 12 to which the board 4 is fixed, and a lower box 11 to which the input/output board 2 is fixed, and in this separated state, the opening of the upper lid 12 and the lower box 11 has a large effect on specification changes. Both the boards 5 and the input/output board 2 can be easily replaced or changed, and the central control board 4 can also be easily replaced or changed.

[0016] Therefore, this control device has storage means 53
The central control means 45 performs arithmetic processing and writes and reads data to and from the storage means 53 according to the program, and the input/output means exchanges control information with the terminal device 3 based on the arithmetic processing of the central control means 45. Give and receive. Specifically, control is performed to perform arithmetic processing based on information input to one of the terminal devices 3 and transmit load control information to other terminal devices 3;
There are controls for transmitting load control information to part or all of the terminal device 3 based on data in the storage means, control for processing information input to the terminal device 3 and displaying the status on an external display device, etc. In addition, by operating an operation switch 47 provided on the central control board 4, initial settings or changes of the arithmetic processing state or data can be made, and the arithmetic processing state or data can be confirmed by displaying on the display 48.

[0017]

As described above, the control device according to claim 1 has the following features:
An input/output board for arranging input/output means in a lower box with an upper opening is installed horizontally, and a first connector with the insertion direction facing upward and a terminal device for external connection exposed from the lower box are installed on this input/output board. furthermore, a central control board having a central control means disposed in the upper lid of the lower opening is installed in a horizontal direction, and a second connector is inserted into the central control board with the insertion direction facing downward and coupled to the first connector. A third connector is provided with the direction facing downward, and a fourth connector is provided which is connected to the third connector with the insertion direction facing upward into the storage board on which the storage means is arranged, and a fourth connector is provided in the center on the input/output board side. Since it is mounted horizontally on the control board, by separating the lower box and upper cover, it is easy to install and remove not only the input/output board and memory board that require changes for various control functions, but also the central control board. can be carried out, making it compact and easy to change specifications.
