<p>An elastic spacer is installed between tapered holes provided at upper and lower circuit boards to couple the circuit boards in parallel and thereby facilitate installation of the circuit boards on a back panel of a CPU unit. A connecting system of circuit boards is provided with first and second tapered holes (17, 27) which are provided at facing positions of first and second circuit boards (20, 21) and an elastic spacer (40) installed to the tapered holes in order to connect the circuit boards in parallel, wherein the elastic spacer (40) is formed with a first spacer (41) which is provided at one end with a tapered part (43) fitted into the first tapered hole (17), and a second spacer (42) which is provided at one end with a tapered part (44) fitted into second tapered hole (27). A spring (48) is inserted between the first and second spacers. The first spacer (41) is fitted in the tapered hole (17) and fastened by a screw (8S) to the first circuit board (20). The second circuit board (21) is fastened by a screw (8L) to the first spacer (41) in a state fitting the second tapered hole (27) over the second spacer (42) with the second circuit board approaching the first circuit board (20).</p> |
