Abstract
(EN)
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.

La présente invention concerne un système de commande de tête de décharge de liquide, qui limite le bruit électromagnétique émis par des cartes de câblage et pour lequel l'entretien des cartes de câblage etc., est extrêmement facile. Un mode de réalisation de la présente invention concerne : une tête à jet d'encre (14) ; une carte de circuit imprimé de commande (18) équipée d'un circuit de commande (102), dans lequel un signal de commande est généré, un câblage de signal de commande pour diviser la sortie du circuit de commande vers au moins deux systèmes de circuit, et de multiples connecteurs (26) pour extraire le câblage du signal de commande pour des systèmes de circuit individuels ; et des cartes de circuit imprimé plates flexibles (FFC) (16) sur lesquelles des connecteurs (24) à connecter aux connecteurs de carte de circuit imprimé de commande sont installés et un motif de signal de commande pour transmettre le signal de commande pour le système de circuit individuel est formé sur une première couche (16C) et un motif potentiel de référence est formé sur une seconde couche (16D). Les multiples FFC sont disposées en parallèles, de sorte que les premières couches soient orientées les unes vers les autres et s'approchent les unes des autres. La carte de circuit imprimé de commande est chargée avec le même nombre de connecteurs que le nombre de cartes de câblage dans des positions où la direction d'insertion-extraction du connecteur de FFC est ouverte.
