There is provided a liquid jetting apparatus including: a liquid jetting head configured to jet liquid; a liquid discharge unit configured to discharge the liquid from the liquid jetting head; a waste liquid recover unit including a waste liquid absorber configured to absorb a waste liquid discharged from the liquid jetting head by the liquid discharge unit and detection electrodes configured to detect a waste liquid amount absorbed into the waste liquid absorber; and a vibration generating source configured to vibrate the waste liquid absorber in a vibration direction, wherein the detection electrodes are disposed to make contact with an end surface defining the waste liquid absorber, and a normal direction of the end surface intersects with the vibration direction.

Liquid jetting apparatus

A liquid jetting apparatus includes: a liquid jetting head in which nozzles for jetting the liquid are formed and which has an actuator for jetting the liquid from the nozzles; an interposer substrate which is provided to the liquid jetting head and on which a driver IC is mounted; a control substrate which controls the liquid jetting head; a wire member which connects the interposer substrate and the control substrate; and a flexible circuit board which connects the interposer substrate and the actuator, wherein the interposer substrate has a first connecting portion to which the wire member is to be connected, and a second connecting portion to which the flexible circuit board is to be connected, and the driver IC is arranged nearer to the first connecting portion than the second connecting portion of the interposer substrate.

A liquid jetting apparatus is provided including: a liquid jetting head having a nozzle formed therein through which the liquid is jetted; a driving unit which is configured to output energy to the liquid jetting head; an energy recovery mechanism which is configured to recover and supply a part of the energy supplied from the driving unit to the liquid jetting head; and a mist removing unit to which the part of the energy recovered by the energy recovery mechanism is supplied so that the supplied energy is used to remove a mist generated under a condition that the liquid jetting head jets the liquid.

There is provided a drive control device including: a wiring board connected to an actuator; two driver ICs each having a plurality of common signal input terminals and selection signal input terminals arranged in one direction; and a control section transmitting a plurality of types of common signals and selection signals to the two driver ICs, respectively, in which the two driver ICs are disposed to face to each other on the wiring board so that the common signal input terminals in the respective driver ICs are each arranged in reverse directions to each other, and the paired common signal input terminals that are disposed in the one direction in the same order when counted from one side are wired respectively.
