Abstract

The second terminal is disposed between the first terminal and the third terminal. The fifth terminal is disposed between the fourth terminal and the sixth terminal. The first cable and the second cable are disposed to at least partially overlap with each other in a direction orthogonal to a direction in which the first terminal and the second terminal are lined up.

Claims (30)

1. A cable group electrically coupled to an ejecting head of a liquid ejecting apparatus, the ejecting head including a first ejecting unit ejecting a liquid by driving a first piezoelectric element, a second ejecting unit ejecting a liquid by driving a second piezoelectric element, and a third ejecting unit ejecting a liquid by driving a third piezoelectric element, the cable group comprising:

a first cable including a first terminal from which a first drive signal input into one end of the first piezoelectric element from a first drive circuit is output, a second terminal from which a second drive signal input into one end of the second piezoelectric element from a second drive circuit is output, and a third terminal from which a third drive signal input into one end of the third piezoelectric element from the first drive circuit is output; and

a second cable including a fourth terminal from which a fourth drive signal input into one end of the first piezoelectric element from the second drive circuit is output, a fifth terminal from which a fifth drive signal input into one end of the second piezoelectric element from the first drive circuit is output, and a sixth terminal from which a sixth drive signal input into one end of the third piezoelectric element from the second drive circuit is output, wherein

the second terminal is disposed between the first terminal and the third terminal,

the fifth terminal is disposed between the fourth terminal and the sixth terminal, and

the first cable and the second cable are disposed to at least partially overlap with each other in a direction orthogonal to a direction in which the first terminal and the second terminal are lined up.

2. The cable group according to claim 1 , wherein

the second cable includes a seventh terminal from which a first reference voltage signal input into another end of the first piezoelectric element is output, and an eighth terminal from which a second reference voltage signal input into another end of the second piezoelectric element is output,

the eighth terminal is disposed between the fourth terminal and the fifth terminal,

the fourth terminal is disposed between the seventh terminal and the eighth terminal, and

the first cable and the second cable are disposed such that the first terminal and the seventh terminal at least partially overlap with each other, and the second terminal and the eighth terminal at least partially overlap with each other.

3. The cable group according to claim 1 , wherein

the first drive signal and the second drive signal have different signal waveforms.

4. The cable group according to claim 3 , wherein

a maximum voltage of the first drive signal is higher than a maximum voltage of the second drive signal.

5. A cable coupled to an ejecting head of a liquid ejecting apparatus, the ejecting head including a first ejecting unit ejecting a liquid by driving a first piezoelectric element, a second ejecting unit ejecting a liquid by driving a second piezoelectric element, and a third ejecting unit ejecting a liquid by driving a third piezoelectric element, the cable comprising:

a first terminal from which a first drive signal input into one end of the first piezoelectric element from a first drive circuit is output;

a second terminal from which a second drive signal input into one end of the second piezoelectric element from a second drive circuit is output; and

a third terminal from which a third drive signal input into one end of the third piezoelectric element from the first drive circuit is output, wherein

the second terminal is disposed between the first terminal and the third terminal.

6. The cable according to claim 5 , further comprising:

a fourth terminal from which a fourth drive signal input into one end of the first piezoelectric element from the second drive circuit is output;

a fifth terminal from which a fifth drive signal input into one end of the second piezoelectric element from the first drive circuit is output;

a sixth terminal from which a sixth drive signal input into one end of the third piezoelectric element from the second drive circuit is output;

a seventh terminal from which a first reference voltage signal input into another end of the first piezoelectric element is output; and

an eighth terminal from which a second reference voltage signal input into another end of the second piezoelectric element is output, wherein

the fifth terminal is disposed between the fourth terminal and the sixth terminal,

the eighth terminal is disposed between the fourth terminal and the fifth terminal,

the fourth terminal is disposed between the seventh terminal and the eighth terminal, and

in a direction orthogonal to a direction in which the first terminal and the second terminal are lined up, the first terminal and the seventh terminal are disposed to at least partially overlap with each other, and the second terminal and the eighth terminal are disposed to at least partially overlap with each other.
