Abstract: A liquid discharge apparatus includes: a frame; a substrate that is fixed to the frame and has a first surface and a second surface; a first circuit that is provided on the first surface; a second circuit that is provided on the second surface; a heat conductive sheet; and a head unit that is driven by a driving signal and is capable of discharging liquid, in which the first circuit includes a driving signal generation circuit that generates the driving signal using a first transistor and a second transistor, the heat conductive sheet is in contact with the frame, the first surface, the first transistor, and the second transistor, and a distance between a portion of the first circuit farthest from the first surface and the first surface is shorter than a distance between a portion of the second circuit farthest from the second surface and the second surface.

Abstract: A liquid discharging apparatus includes a head unit driven by a drive signal to discharge a liquid; a substrate; and a first transistor and a second transistor provided on the substrate and configured to generate the drive signal. In the substrate, a screw hole is provided between the first transistor and the second transistor.

Abstract: A printing apparatus includes a cartridge, and a wiring cable which can transmit an electrical signal to the cartridge. The carriage is provided with a connector unit and a wiring board in a holder unit on which the cartridge is mounted. First and second electrode portions, and a connector unit are arranged on a first face of the wiring board. The wiring board is arranged at a position of being overlapped with the cartridge in a direction which goes along an arrow Y. A width of the wiring board in an arrow X direction is the same as a width of a cartridge arranging region in the holder unit, or is smaller than that.
