Image display system, image display apparatus and peripheral devices of image display apparatus
An image display system has an image display apparatus and a peripheral device that can be mounted on the image display apparatus. The image display apparatus includes a first electrode for electrically connecting the image display apparatus and peripheral device, and the peripheral device includes a second electrode for electrically connecting the image display apparatus and peripheral device. These electrodes are placed so as to have contact with one another when the peripheral device is mounted on the image display apparatus. In addition, the image display system moves the mounting position of the peripheral device on the image display apparatus as appropriate. The system minimizes cables used for electrical connections between the image display apparatus and peripheral devices, makes the apparatus compact and allows adoption of a variety of layouts.

an image display apparatus provided with a first electrode and a second electrode;
a peripheral device provided with a third electrode and a fourth electrode, which can be mounted onto said image display apparatus; and
a guide for directing a path when a mounting position of said peripheral device on said image display apparatus is changed, wherein
said first and second electrodes are placed along said guide,
said first electrode and said third electrode are for supplying power from said image display apparatus to said peripheral device,
said second electrode and said fourth electrode are for transmitting a signal between said image display apparatus and said peripheral device, and
said first and second electrodes are placed in such a way as to directly contact said third and fourth electrodes, respectively, by positioning said peripheral device to any of a plurality of mounting positions along said guide.
