PURPOSE:To progress effectively miniaturization and also to progress safety and countermeasure against dust proof with simple constitution by inserting a brush into a brush inserting inlet from the outside of a cylinder and connecting and loading it to the slip ring. CONSTITUTION:The slip ring 30 and the 1st, 2nd and 3rd brushes 38A, 38B and 38C are fitted to a gap of the turning side rotary transformer 26, a video head base 40 or a piezoelectric effect element 33. Since the cylinder assembling state of the upper cylinder 21, the lower cylinder 20 and a motor assembly 41 is formed with a minimum component length, the miniaturization of the video recorder main body is urged. With the protection countermeasure at application of a high voltage, the safety is improved and the dust proof countermeasure preventing the adhesion of dust is improved. |
