Title:
LIQUID-DISCHARGING HEAD-DRIVING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/162938
Kind Code:
A1
Abstract:
The present invention provides a liquid-discharging head-driving system, which limits electromagnetic noise emitted from wiring boards and for which ease of maintenance of the wiring boards, etc. is excellent. One embodiment of the present invention is provided with: an inkjet head (14); a driving circuit board (18) equipped with a driving circuit (102) in which a drive signal is generated, drive signal wiring for splitting the output of the driving circuit to at least two circuit systems, and multiple connectors (26) for extracting the drive signal wiring for individual circuit systems; and flexible flat circuit boards (FFC)(16) on which connectors (24) to be connected to the driving circuit board connectors are installed and a drive signal pattern for transmitting the drive signal for the individual circuit system is formed on a first layer (16C) and a reference potential pattern is formed on a second layer (16D). The multiple FFCs are disposed in parallel so that the first layers face and approach each other. The driving circuit board is loaded with the same number of connectors as the number of wiring boards at positions where the FFC connector insertion-extraction direction is open.
