The invention claimed is: 1. A head-mounted audio/video playback system comprising: (i) a main-body unit comprising: a left case comprising a left speaker and a recessed part in which a unit-connection terminal provided with a plurality of electrical terminals is provided; a right case comprising a right speaker and a recessed part in which a unit-connection terminal having a same configuration as the unit-connection terminal of the left case is provided; a coupling unit for integrally coupling the left case and the right case; a left audio-signal transmission line for transmitting a left audio signal, which is supplied to the left speaker; a right audio-signal transmission line for transmitting a right audio signal, which is supplied to the right speaker; and a video-signal transmission line, connected to the electrical terminals included in the unit-connection terminal of the left case and the electrical terminals included in the unit-connection terminal of the right case, for transmitting a video signal, and (ii) a video playback unit that can be removably connected to one of the left case and the right case of the main-body unit, the video playback unit comprising: a display element for displaying images; a main body adapted to be fitted into the recessed part of said one of the left case and the right case such that a connection element of the video playback unit provided on the main body is connected to the corresponding one of the unit-connection terminals; and display-element driving means for driving the display element according to a video signal input from the connection element, wherein when the display element is connected to the left case, the display element is positioned in front of a left eye of a user, and when the display element is connected to the right case, the display element is positioned in front of a right eye of the user. 2. A head-mounted audio/video playback system according to claim 1, wherein the unit-connection terminal of the left case and the unit-connection terminal of the right case each include an electrical terminal for detecting left/right unit mounting position, and wherein the video playback unit further comprises control means for determining whether the video playback unit is connected to the left case or the right case by detecting the electrical terminal for detecting left/right unit mounting position and for controlling the display-element driving means according to the determination result so that an image displayed on the display element is properly oriented vertically and horizontally. 3. A head-mounted audio/video playback system comprising: (i) a main-body unit comprising: a left case comprising a left speaker and a unit-connection terminal provided with a plurality of electrical terminals; a right case comprising a right speaker and a unit-connection terminal having a same configuration as the unit-connection terminal of the left case; a coupling unit for integrally coupling the left case and the right case; a left audio-signal transmission line for transmitting a left audio signal, which is supplied to the left speaker; a right audio-signal transmission line for transmitting a right audio signal, which is supplied to the right speaker; and a video-signal transmission line, connected to the electrical terminals included in the unit-connection terminal of the left case and the electrical terminals included in the unit-connection terminal of the right case, for transmitting a video signal; (ii) a video playback unit that can be removably connected to one of the left case and the right case of the main-body unit, the video playback unit comprising: a display element for displaying images; a connection element adapted to be connected to the unit-connection terminals; and display-element driving means for driving the display element according to a video signal input from the connection element, wherein when the display element is connected to the left case, the display element is positioned in front of a left eye of a user, and when the display element is connected to the right case, the display element is positioned in front of a right eye of the user; and (iii) a battery unit comprising: a battery; and a connection terminal adapted to be connected to the unit-connection terminals and to supply power from the battery, wherein the video playback unit is removably attachable to both the left case and the right case to be connected to the corresponding one of the unit connection terminals, and the battery unit is removably attachable to both the left case and the right case to be connected to the corresponding one of the unit connection terminals. 4. The head-mounted audio/video playback system according to claim 3, wherein the main-body unit further comprises a power-supply line, connected to the electrical terminals of the unit-connection terminal of the left case and the electrical terminals of the unit-connection terminal of the right case, for supplying power, wherein the video playback unit further comprises an input power switching circuit that detects whether the power-supply line can supply power and whether the battery unit can supply power, and wherein when both of the power-supply line and the battery unit can supply power, the input power switching circuit stops the power supplied from the battery unit and allows the power to be supplied only from the power-supply line.
