Lever Motor Drive Circuit
This printer has a DC type lever motor for the purpose described below.
Adjustment of paper path changeover timing
Adjustment of shaft rotation position
Rotation of the lever motor starts changeover of the paper path and the platen open/close
operation. An NPN Darlington transistor is used for lever motor drive. Due to the structure of
the lever motor, a brake circuit is not required. The lever motor is driven using the ELV_M1
output signal from the GA.
The lever motor rotates when LEV_M1 = LOW. The motor cannot be driven when the VCC-
PWR is not being supplied. Furthermore, the Q41 NPN Darlington transistor incorporates a CE
Zener to perform kickback protection.
