| 1. An electronics device system including a first electronics device and a second electronics device to which said first electronics
device is attached by a rotational operation, said electronics device system comprising:
a first terminal group disposed on said first electronics device, said first terminal group including terminals arranged in
one direction; and
a second terminal group disposed on said second electronics device and including terminals arranged so as to correspond to
the terminals of said first terminal group, said first terminal group sliding on said second terminal group from one end thereof
in the direction of arrangement of said terminals when an attachment operation for attaching the first electronics device
to said second electronics device is performed, and the terminals of said first terminal group being connected to the terminals
of said second terminal group one on one to form a plurality of terminal pairs when said first and second electronics devices
are kept in an attachment completion state,
wherein said terminal pairs include first and second terminal pairs, said second terminal pair being connected later than
said first terminal pair when said attachment operation of said first and second electronics devices is performed, and said
second terminal pair being disconnected earlier than said first terminal pair when a detachment operation for detaching said
first electronics device from said second electronics device is performed, and
wherein said first terminal pair is set to high impedance after said second terminal pair has been disconnected and while
said first terminal pair is connected.
