4-3-3 Buzzer and Cash Drawer Circuits

1) Buzzer Driving Circuit

The Buzzer is used to inform several kinds of states which occur under system operating and gives some information to users by controlling the P86 of CPU (UPD70F3107)

[Figure 4-6 Buzzer Block Diagram]

2) Cash Drawer Driving Circuit

The circuit is used for opening cash drawer and driven by the Q10, Q11(2SD2170). When its state is high level signal, Q10 or Q11 (2SD2170) drive the solenoid to open the cash drawer. As an optional item, we provide sensor switch (we call it a compulsory switch) which checks the drawer whether it is opened or not. This sensor switch turns on for the drawer open condition, and turns off for the other.

※Caution : Make sure that the Cash Drawer solenoid resistance is more than 20Ω.
