PURPOSE:To obtain a signal transmitting line strong to the noise of a high frequency area especially by executing the grounding through a conducting rotary shaft, a conducting holding core bar and a ground exclusive-use contact. CONSTITUTION:A power supplied through a slip ring 2 from a power source device 9 is supplied through a lead wire 7 for transmission to an electronic circuit substrate 5 in a rotary drum 6. The lead wire 7 is passed in a hollowed conducting rotary shaft 1' and the good quality power source transmission without a noise can be executed. The grounding of the substrate 5 is executed to the external part directly from the top of the substrate through the rotary shaft 1', a conducting holding core bar 1 and a ground exclusive-use contact 3 fitted to the core bar 1 by a contact terminal 3'. The contact 3 is fitted in the shaft direction of the rotary shaft 1' and the stable ground line with a low impedance can be formed. |
