Abstract: An image pickup apparatus including a lens barrel, a hollow shaft, a base, electric wiring, and a protection member. The lens barrel has a lens and an image pickup device embedded therein. The hollow shaft is rotatable about an axis intersecting with an optical axis of the lens. The axis serves as a central axis of the hollow shaft. The base supports the lens barrel in a rotatable manner by using the hollow shaft. The electric wiring extends through the inside of the hollow shaft to electrically transmit an image pickup signal of the image pickup device. The protection member is provided in the hollow shaft so as to prevent the electric wiring from coming into contact with the hollow shaft.

Abstract: A camera apparatus includes a base; an outer case assembled on the base; an inner case assembled in the outer case; a supporting member assembled in the inner case; a camera and a board assembled in the supporting member; a cooling fan for cooling the board, and so forth. The cooling fan is provided in the inner case to blow cooling air over the board. An air inlet is located on an air intake side of the cooling fan, whereas an air outlet is located in an extension of an air discharge side of the cooling fan along the board.

Abstract: Disclosed is a head system including a plurality of recording heads for azimuth recording. The system includes a first recording head having a plurality of magnetic gaps having a first azimuth angle, and a second recording head having a plurality of magnetic gaps having a second azimuth angle different from the first azimuth angle. After first magnetization patterns are formed on a recording medium by the first recording head, second magnetization patterns are formed by overwriting side edge portions in the formation direction of the first magnetization patterns by the second recording head. This makes it possible to prevent the worsening of the accuracy of the magnetization pattern width due to a relative height stagger (offset) between the heads, to thereby enhance the accuracy of the magnetization pattern width, and to achieve high-density recording.
