Software Card Lock

Sets or acquires the Lock/Unlock status of the software-type card lock switch.

This machine has a card lock mechanism that is on the card case to prevent accidental removal of the card. This mechanism has a software driver that detects the released state of this lock and executes the appropriate file closing procedure. However, some types of cards, depending on the card shape, can not be fastened by the lock switch. If this is the case, even if a card is present it will not be detected. This function is provided to handle this type of card.

To use a card for which the card lock mechanism can not be used, call this function in advance to set the software lock switch to ON. Now a card can be detected when it is inserted or removed.
