<p>PURPOSE:To prevent springing out of a battery due to foregetting to lock, loss of memory information, etc., by a method wherein when an IC memory card is connected to an information processor while a battery holder is being not locked, a card detecting circuit in the information processor is kept incapable of being operated. CONSTITUTION:When a card side connector 2 of an IC memory card 1 is connected to an instrument connector 9 side of an information processor 8, respective card detecting pins 2b, 9b come in mutual contact with ground electric potential pins 2a, 9a. Therefore, when input of a battery 12 comes to be of an 'L' state, its output comes to be of an 'L' state concurrently therewith. Therefore, the information processor 8 detects that the IC memory card 1 is connected, and the IC memory card 1 comes capable of being operated. That is, when the IC memory card 1 is connected to the information processor 8 while a battery holder 3 is not locked with a slide type locking device 5, a card detecting circuit 10 is not operated by action of a slide switch 7.</p> |
