Description

Technical Field

[0001] The utility model relates to the technical field of crystal oscillator devices, and more specifically, to a crystal oscillator device for a thermal printer microprocessor. Background Art

[0002] Crystal oscillators are widely used in communications, radar, measuring instruments, and navigation equipment because they can generate AC signals with highly stable frequencies. In particular, they are used in thermal printer microprocessors, playing an indispensable role in this field.
