Abstract
An ink tank receives data signals from a printer and an LED provided on the ink tank is driven on the basis of the received data signals. The LED is driven in an inactive time period that is different from the time period in which the date signals are input to the ink tank.
Claims18
A signaling module provided in a liquid container mountable on a printer main body, the signaling module comprising:
- a data signal contact that electrically contacts the printer main body and receives data signals including a control code selected from a control code group including an ON code and an OFF code from the printer main body;
- a light-emitting unit capable of emitting light;
- and
- a control unit capable of allowing the light-emitting unit to be turned on, on the basis of the ON code included in the data signals to be input from the printer main body to the data signal contact, and of allowing the light-emitting unit to be turned off, on the basis of the OFF code included in the data signals to be input from the printer main body to the data signal contact,
- wherein switching between a ON state and a OFF state of the light-emitting unit by the control unit is performed during an inactive period during which the data signals from the printer main body are not input to the data signal contact.
A liquid container mountable on a printer main body, the liquid container comprising:
- a data signal contact that electrically contacts the printer main body and receives data signals including a control code selected from a control code group including an ON code and an OFF code from the printer main body;
- a light-emitting unit capable of emitting light;
- and
- a control unit capable of allowing the light-emitting unit to be turned on, on the basis of the ON code included in the data signals to be input from the printer main body to the data signal contact, and of allowing the light-emitting unit to be turned off, on the basis of the OFF code included in the data signals to be input from the printer main body to the data signal contact,
- wherein switching between an ON state and an OFF state of the light-emitting unit by the control unit is performed during an inactive period during which the data signals from the printer main body are not input to the data signal contact.
A printer including a printer main body having a data signal line capable of communicating data signals, including a control code selected from a control code group including an ON code and an OFF code, and a liquid container to be detachably mounted on the printer main body,
- wherein the liquid container comprises a data signal contact that electrically contacts the data signal line, a light-emitting unit capable of emitting light;
- and a control unit capable of allowing the light-emitting unit to be turned on, on the basis of the ON code included in the data signals to be input from the printer main body to the data signal contact and of allowing the light-emitting unit to be turned off, on the basis of the OFF code included in the data signals to be input from the printer main body to the data signal contact,
- wherein switching between an ON state and an OFF state of the light-emitting unit by the control unit is performed during an inactive period during which the data signals from the printer main body are not input to the data signal contact.
