Further, even if the number of the mailbox units 2 constituting the mailbox unit is increased or decreased, it is possible to select and use only the necessary signal line connection terminals within the range of the number of signal line connection terminals provided in the connection harness HC in advance. Good. Further, in the case where the number of the mailbox parts 2 to be connected to the control box A is changed by sequentially increasing or decreasing the connection harness HC by such a method,
If the number of mailbox parts 2 constituting one unit is different, the numbers to be assigned to the mailbox parts for control are also different. In other words, when the connection harness HC can connect the control box A and the mailbox unit 2 to form a maximum of 8 × 8 matrix wiring, the mailbox unit that constitutes one unit has five stages and is configured to have seven units. In such a case, a 5 × 7 matrix wiring is configured, but in this case, the controller of the control box A needs to execute a control program capable of signal processing on the 5 × 7 matrix wiring. Therefore, in the mailbox unit proposed in claim 2,
A jumper board is provided as the external setting means 15 so that the controller 10 side of the control box A can discriminate this state every time the number of the mailbox parts 2 constituting one unit is changed. A 3-bit setting signal to be set is fetched into the controller 10 side so that the control program to be executed can be switched and set.
