Title:
LIQUID DISCHARGE DEVICE
Document Type and Number:
Japanese Patent JP2018034312
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce an impact due to variation in characteristics of mutual circuit elements when D-class-amplifying a drive signal to a piezoelectric element 60.SOLUTION: A printing device 1 includes: a correction circuit 54a for correcting data dAp on the basis of correction data Ac and outputting data dA; a drive circuit 5a for converting the data dA into an analog signal and D-class-amplifying the converted data, and then outputting a drive signal COM-A; a correction circuit 54b for correcting data dBp on the basis of correction data Bc and outputting data dB; and a drive circuit 5b for converting the data dB into an analog signal and D-class-amplifying the converted data.SELECTED DRAWING: Figure 2
