If the time has elapsed without the door (3) being opened even once.

Assuming that the request for carrying out the currently selected medicine has been cancelled, the process moves to (to) (to) and sends a signal to nine lock control circuits αe and one lamp control circuit α to lock the corresponding lock (6).

Turn off the lamp (4). On the other hand, if the authorized person opens the door (3)Y within the specified time, the contact of the switch (5) will open.

Calculation @ti4 knows that the door (3) has been opened by checking the output signal of the switch signal generation circuit αη, and (3)
karake) Proceed to the following operations. That is, computer I is the door (3)
Within the specified time after the container (1) has been opened, the authorized person shall repeat and monitor the actions of (H, (B), (B)). If it has been taken out, the weight indicated by the weight detection device (8) will be zero, and if it is returned to the box (2), the weight will not be zero, so calculation tfi (I4 sends signal 2 to channel switching circuit αB) By checking the output of the weight detection device (8), it is possible to detect whether the container (1) is taken out or taken out.If the container (1) is not taken out even once within the specified time, the door (3) closes again. When the pressure is reached, the transition shifts from (B) to (To) Shio), and assuming that the pressure for taking out the medicine is no longer necessary, the computer 04 sends the lock control circuit αe and lamp control circuit QSK signals to lock the lock (6). lamp(
4) Turn off the light. Further, if the specified time has elapsed without container (1) being taken out, the calculator αa moves from (ko) to (goods) and thereafter. First, at fA, computer 04) sends a signal to the alarm device (I trench and sounds an alarm, (x),
(Repeat -1.

Check to see if the container (1) has not been taken out and the door (3) is left open. Naturally, the alarm continues to sound during this time.

Then, when the authorized person notices the alarm and closes the door (3), the computer 04) will be able to take out the medicine within the specified time, just as if the container (11) had never been taken out and the door (3) was closed. Assuming that the request has been canceled, send a signal to the alarm device tJ3 at (n) to stop the alarm, and then (@.
