DRIVE CIRCUIT FOR RECORDING DEVICE, LIGHT-EMITTING ELEMENT UNIT, AND RECORDING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a novel technology for suppressing a circuit scale of a recording device.SOLUTION: A drive circuit for a recording device comprises: a first driver DRarranged on an electric path from a first current supply part 110 to a first connection part; a second driver DRarranged on an electric path from a second current supply part 120 to the first connection part; a third driver DRarranged on an electric path from the second current supply part 120 to a second connection part; and a switch part 130 configured to selectively connect the second current supply part 120 with one of the second driver DRand the third driver DRand to disconnect between the second current supply part 120 and the other of the second driver DRand the third driver DRwhen the second current supply part 120 is connected with the one driver.SELECTED DRAWING: Figure 1
