LIQUID EJECTION HEAD DRIVING SYSTEM
First Claim
1. A liquid ejection head driving system comprising:
- a liquid ejection head including a plurality of nozzles that eject a liquid and a plurality of pressurizing elements that pressurize the liquid ejected from the nozzles;
a driving circuit substrate including a driving signal generation unit in which a driving signal supplied to the plurality of pressurizing elements is generated, a driving signal wiring that branches an output of the driving signal generation unit into two or more systems, and a plurality of circuit-side connectors that extract the driving signal wiring for each of the systems;
a support member that supports the driving circuit substrate; and
the same number of wiring substrates as that of the system in which a wiring-side connector connected to the circuit-side connector is installed, a driving signal pattern for transmitting the driving signal for each of the systems is formed on a first surface, and a reference potential pattern of the driving signal is formed on a second surface on an opposite side to the first surface, wherein;
the plurality of wiring substrates are disposed in parallel so as to be brought close to each other by causing the first surfaces to face each other, andthe driving circuit substrate is configured such that the same number of circuit-side connectors as the number of wiring substrates are mounted at a position where a direction of insertion and extraction of the wiring-side connector of the wiring substrate is released.

Abstract
A liquid ejection head driving system includes an ink jet head, a driving circuit substrate provided with a driving circuit in which a driving signal is generated, a driving signal wiring that branches an output of the driving circuit into two or more systems, and a plurality of connectors that extract the driving signal wiring for each system, and a flexible flat substrate (FFC) in which a connector connected to a connector of the driving circuit substrate is installed, a driving signal pattern for transmitting the driving signal for each system is formed on a first layer, and a reference potential pattern is formed on a second layer. The driving circuit substrate is configured such that the same number of connectors as the number of wiring substrates are mounted at a position where a direction of insertion and extraction of the connector of the FFC is released.
