<p>PROBLEM TO BE SOLVED: To provide an attachment mechanism which can properly cope with the hot line attachment/detachment of a unit device in an information processing system where plural unit devices are connected to a unit attachment substrate of an information processor. SOLUTION: The tip positions of contacts of three connectors 31a, 32a and 33a placed at the side of a unit device 22a are shifted from each other when viewed in the direction where they are put into a unit device attachment substrate 24a. On the other hand, the contacts of three connectors 41a, 42a and 43a placed at the side of the substrate 24a are located at the same position. Therefore, the contact timing is shifted from each other among the contacts of the device 22a and the substrate 24a in the order of uses for the GND, signals and the power supply respectively.</p> |
