Abstract: A printer includes a light source module including an ejecting head that ejects a UV ink onto a medium. The UV ink hardens when irradiated with a UV light ray. The light source module includes an irradiator that irradiates the UV ink with the UV light ray. The printer may include a guide shaft to/from which the light module is attachable/detachable and a driving controller that performs control of the irradiator. The light source module includes, in addition to the irradiator, a memory module that stores therein information indicating a light irradiation feature of the irradiator. The driving controller performs control of the irradiator by using the information indicating a light irradiation feature of the irradiator.

Abstract: A liquid discharging apparatus includes a print head that has a driving element and discharges a liquid, a drive signal generation circuit that generates the drive signal based on a drive signal generation control signal for controlling generation of the drive signal, and a drive circuit substrate on which the drive signal generation circuit is provided. The drive circuit substrate has an input connector that inputs the drive signal generation control signal into the drive circuit substrate and an output connector that outputs the drive signal from the drive circuit substrate. A distance between the input connector and the output connector is shorter than a distance between the drive signal generation circuit and the input connector. The distance between the input connector and the output connector is shorter than a distance between the drive signal generation circuit and the output connector.
