Recording head

摘要

A recording head includes: a recording element substrate having a recording element and a logic circuit cofigured to control driving of the recording element; and an electric wiring member cofigured to provide a wiring layer that has a first group of a plurality of terminals, a second group of a plurality of terminals, and a plurality of signal lines configured to connect the first group of terminals to the second group of terminals; wherein the plurality of signal lines includes a plurality of logic signal lines including a logic power source line, a logic ground line, and at least first and second logic signal lines, and wherein, on the wiring layer, a line pattern connected to one of the logic power source line and the logic ground line is disposed along the first and second logic signal lines.

1. A recording head, comprising:
a plurality of recording element substrates having a recording element and a logic circuit cofigured to control driving of the recording element; and an electric wiring member cofigured to provide a wiring layer that has a plurality of first groups of a plurality of terminals for connecting to the plurality of recording element substrates, a second group of a plurality of terminals for connecting to a recording apparatus, and a plurality of signal lines configured to connect the plurality of first groups of terminals to the second group of terminals, wherein the plurality of signal lines include a plurality of clock lines for transmitting a clock signal to the recording element, a plurality of data lines for transmitting data to the recording element, and a ground line configured to connect the first group of terminals and the second group of terminals, wherein the ground line has a plurality of branched lines branched off from the ground line, one end side of the plurality of branched lines extends to a vicinity of the second group of terminals without being connected to the second group of terminals, wherein the clock lines are not directly adjacent to the data lines, and wherein one of the branched lines is disposed between a clock line of the clock lines and a data line of the data lines.
