AI Technical Summary

Technical Problem

Existing liquid ejection devices, such as inkjet printers, face challenges in minimizing device size due to the need for a movement area for wiping members, which often leads to increased dimensions in the direction of movement.

Method used

The liquid dispensing device incorporates a wiping mechanism with a wiper portion that moves in a direction intersecting the circuit board, where at least a part of the electrical component unit and power supply unit overlap with the wiping mechanism, allowing for reduced dimensions in the direction of movement.

Benefits of technology

This configuration enables the device to be made smaller by overlapping components in the direction of wiper movement, improving maintainability and reducing the overall size without compromising functionality.

Abstract

To solve the problem in which: a moving region of a wiping member needs to be secured at the outside of an ink discharge region and therefore a device is easily increased in size in a moving direction of the wiping member in a configuration in which the wiping member moves in a direction along an ink discharge surface of an ink discharge head.SOLUTION: A liquid discharge device includes: a liquid discharge head which discharges liquid to a medium; a wiping mechanism which wipes a liquid discharge surface of the liquid discharge head and has a wiper section for wiping the liquid discharge surface by moving in a direction along the liquid discharge surface; an electrical section which is positioned at a portion related to control of the device and has a substrate; and a power supply section to be a power supply source. A moving direction of the wiper section is a direction crossing a surface of the substrate. At least a part of the electrical section, at least a part of the power supply section, and at least a part of the wiping mechanism overlap in the moving direction of the wiper section.SELECTED DRAWING: Figure 7
