PROBLEM TO BE SOLVED: To provide a circuit board and its mounting structure which are small in size, reduced in cost, and capable of housing a large number of input/ output signal wires, and especially a main distributing device (MDH) board where plug-in pins can be surely inserted into or drawn out from the board. SOLUTION: A rectangular circuit boards 17A/19A can be mounted on a board mounting board 14 freely detachable by inserting or drawing its one side (e.g. short side) into or out of the board mounting board 14, connectors 6b/5b through which signals are transmitted to an outer equipment from the circuit boards 17A/19A and vice versa are provided to the one or two adjacent sides of the circuit board 17A/19A, and a large number of input/output signal wires are arranged dispersedly. It is preferable that a circuit board be an MDF board which is employed in a communication equipment. The MDF board and a robot which inserts or draws plug-in pins into or out of the board are inserted into an adjacent slot, and a first angle member provided to the MDF board and a second angle member provided to the robot are engaged with each other freely slidably so as to be ensured of mutual positional accuracy. |
