Abstract

PURPOSE: To realize this portable computer, which is immune to noise, having light weight with low energy consumption by providing a means to separate the connection part of a peripheral equipment from the main body of the computer and connecting a signal line through a switcher.
CONSTITUTION: The main body 10 of the computer and a connection part 11 of the peripheral equipment are connected by an address signal 12, data signal 13 and power source 14. When the connection part 11 is connected to the main body 10, the signal line is connected after a detector/switcher 19 detects that the main body 10 is connected the connection part 11. When the connection part 11 is disconnected, this is detected and the signal line is discon nected. The above-mentioned signal line and a power supply line are connected in parallel to control circuits 15-18 of respective equipments. On the other hand, the peripheral equipments are connected to connecting terminals provided on the respective control circuits. The diagram shows a system for adding the connection parts corresponding to the number of the peripheral equipments to be connected. When the number of the peripheral equipments to be connected is one, one peripheral equipment connection part 20 is prepared and when connection terminals 23 and 24 in a main body 33 of the computer are connected, the peripheral equipment can be connected to a connecting terminal 26. In the case of further adding the peripheral equipments, the connecting terminals are successively added.
