PURPOSE:To obtain a vessel whose both faces are usable, by arranging the vessel and each part symmetrically with respect to the axis, and providing an address display means symmetrically with respect to the same axis also. CONSTITUTION:When a vessel body 1 is loaded to an image pickup device, a disc driving source is brought into contact with a disc flange part 2, and a display driving source is brought into contact with a display plate flange part 7. At this time, the presence or the absence of a projecting part 12 is detected mechanically or electrically, and displayed on the image pickup device side whether the vessel body 1 is loaded face up or face down. A magnetic head is brought into contact with a magnetic disc 3 through an aperture part 8a. The arrow of a display plate 4 is moved by one-frame and recording of one frame of picture information on this magnetic disc is displayed together with a number 5. When 40-frame of picture information are recorded on the magnetic disc 3, the arrow 6 is rotated once to display it. When the vessel body 1 is loaded again face down, 40-frame of picture information are recorded similarly because each part of the vessel is constituted symmetrically with respect to an axis X0-X0'. |
