Abstract: Disclosed herein are a drip coffee machine and a liquid discharge device used therefor including: a liquid providing module having a discharge pipe discharging liquid to coffee beans; a rotation module having an actuator generating rotational force, a driven gear rotated by receiving the rotational force, and a base plate rotated by being connected to the driven gear, the base plate being configured to move the discharge pipe along a rotation trajectory when rotated; and a translation module including a translation drive unit having an elastic pull member elastically deflecting the discharge pipe along a translation trajectory, an adjustment cam installed to be rotatable with respect to the base plate to adjust the position of the discharge pipe elastically deflected within the translation trajectory by the elastic pull member in the one direction or the other direction opposite to the one direction and having its outer circumferential surface in contact with the discharge pipe, and an intermediate unit trans
