Title:
LIQUID DISCHARGE DEVICE
Document Type and Number:
Japanese Patent JP2022104714
Kind Code:
A
Abstract:
To provide a liquid discharge device that can reduce the risk that an ink discharge property may deteriorate.SOLUTION: The liquid discharge device comprises an integrated circuit that outputs a modulation signal, an amplification circuit that outputs an amplified modulation signal by driving a transistor, and a demodulation circuit including an inductance element, which output a driving signal. The inductance element has: a first side part provided with a first terminal; a second side part positioned to oppose to the first side part and provided with a second terminal; a third side part and a fourth side part crossing the first side part and the second side part; and lead member connected to the first terminal and the second terminal, including a first inflection point and a second inflection point; and a guide member provided to surround the lead member. Virtual straight lines connecting a lead part in the lead member to the first terminal and to the second terminal cross each other at center parts of the virtual straight lines. A shortest distance between the transistor and the third side part is below a shortest distance between the transistor and the first side part and is below a shortest distance between the transistor and the second side part.SELECTED DRAWING: Figure 13
