POWER SOURCE CONTROL DEVICE FOR INKJET HEAD AND INKJET PRINTING APPARATUS

摘要

The device and method handles increases in power consumed by an inkjet head. When greater-than-specified electric power is being input from both the first input section and the second input section, the control section controls the state of connection so as to prioritize connection of the second power source to the inkjet head driving system over the first power source.

主权项

1. A power source control device for an inkjet head, comprising:
a first input section which receives electrical power supplied from a first power source; a second input section which receives electrical power supplied from a second power source having higher power supply capability per predetermined time interval than the first power source; and a control section which controls a connection status between an inkjet head driving system and the first and second input sections such that any one of the first and second power sources is connected to the inkjet head driving system, wherein the control section controls the connection status in such a way as to connect the second power source, preferentially over the first power source, to the inkjet head driving system when a predetermined amount or more of electrical power is input from both the first and second input sections.
