<p>PURPOSE:To safely and detachably use a display device for a high voltage use by detachably connecting the display device to a system mainbody through a connector means and supplying the power of a low voltage to the display device. CONSTITUTION:When the connector 13 is connected to the display device 12, and the device 12 is installed on the system mainbody 11, a display circuit 14 and a power device 15 in the mainbody 11 are respectively and electrically connected to the device 12 through the connector 13. Thus, a display part 16 in the device 12 obtains a display signal from the circuit 14, power from the device 15, and the part comes to a display possible state. In such a case, the power voltage of the low voltage is outputted from the device 15 and it is converted into a high voltage required for display through a D/C-C/D converter 17, and is given to the display part 16. Since the high voltage is not given to the connector part, the display device can safely and detachably be used.</p> |
