Abstract
Provided is a signal processing circuit including: a first terminal to which a control signal including identifier information indicating a control target is input; a determination circuit configured to determine the control target based on the identifier information; and a second terminal that is different from the first terminal. When the determination circuit determines that the control target is the signal processing circuit, the signal processing circuit performs a process in accordance with the control signal. When the determination circuit does not determine that the control target is the signal processing circuit, the signal processing circuit outputs the control signal from the second terminal.
Claims12
A signal processing circuit comprising:
- a first terminal to which a control signal including identifier information indicating a control target is input;
- a determination circuit configured to determine the control target based on the identifier information;
- and
- a second terminal that is different from the first terminal,
- wherein when the determination circuit determines that the control target is the signal processing circuit, the signal processing circuit performs a process in accordance with the control signal,
- wherein when the determination circuit does not determine that the control target is the signal processing circuit, the signal processing circuit outputs the control signal from the second terminal, and
- wherein the control signal is input to the first terminal from the same control circuit in both a case where the control target is the signal processing circuit and a case where the control target is not the signal processing circuit.
An image forming apparatus comprising:
- a main body including a control circuit;
- and
- a flexible cable used for connecting the control circuit and a reading unit to each other,
- wherein the control circuit is configured to output control signals, which include respective identifier information indicating at least one control target selected from a plurality of signal processing circuits of the reading unit, to the reading unit via the flexible cable, and
- wherein both of a first control signal whose control target is a first signal processing circuit of the plurality of processing circuits, and a second control circuit whose control target is not the first signal processing circuit are output from the same control circuit to one terminal of the first processing circuit.
