[0095] Composition of printing system:

[0096] Next, embodiments of the present invention will be described based on examples. figure 1 It is an explanatory diagram showing the general configuration of the printing system in the first embodiment. The printing system includes a printer 20, a computer 90, and an ink cartridge 100. The printer 20 is connected to the computer 90 via the connector 80.

[0097] The printer 20 includes a sub-scanning and conveying mechanism, a main scanning and conveying mechanism, a head driving mechanism, and a main control unit 40 for controlling each mechanism. The sub-scanning and conveying mechanism includes a paper feed motor 22 and a platen 26, and conveys the paper P in the sub-scanning direction by transmitting the rotation of the paper feed motor to the platen. The main scanning conveying mechanism includes a carriage motor 32, a pulley 38, a driving belt 36 spanned between the carriage motor 32 and the pulley 38, and a sliding shaft 34 arra...

[0153] Picture 10 It is a first explanatory diagram showing the electrical structure of the printer in the second embodiment. Picture 10 The parts required for processing related to the ink cartridge 100A in the second embodiment are emphatically depicted. Correct Picture 10 The structure of the main control unit 40A is marked with symbols as follows: Figure 5 The main control unit 40 described has the same structure. Figure 5 Add A to the end of the symbol.

[0154] The sub-control section 50A in the second embodiment includes seven switches SW1A to SW7A. These seven switches SW4A to SW7A are the same as the switches SW1 to SW3 of the first embodiment, and operate under the control of the second control circuit 55A.

[0155] The first switch SW1A is a single-channel analog switch. One terminal of the first switch SW1A is connected to the drive signal generating circuit 42A of the main control unit 40, and the other terminal is connected to the sixth switch SW6A and the fifth...

[0172] Figure 13 It is an explanatory diagram showing the electrical structure of the printer in the third embodiment. Figure 13 The electrical structure of an ink cartridge 100B is emphasized. in Figure 13 Here, the configuration of the sub-control unit 50 of the printer 20 schematically shows a state in which one ink cartridge 100B is selected as the target of the remaining ink level determination process or the memory access process. That is, in Figure 13 In the illustration, the second switch SW2 and the other five ink cartridges are omitted. In fact, the other 5 ink cartridges have Figure 13 The ink cartridge 100B shown has the same structure.

[0173] The configuration of the printer 20 (the main control section 40 and the sub-control section 50) in the third embodiment is the same as the configuration of the printer 20 in the first embodiment, so the description thereof is omitted. In the ink cartridge 100B in the third embodiment, instead of the voltage stabilizer 3...

Abstract

A liquid container attachable to a liquid jetting apparatus is provided with an electric circuit, which includes a first electric device and a second electric device, a first terminal, and a second terminal. The electric circuit can execute first communication with the first electric device and second communication with the second electric device, by using an inter-terminal potential difference between a potential which the liquid jetting device inputs to the first terminal, and a potential which the liquid jetting device inputs to the second terminal. The electric circuit can execute the first communication and the second communication by discriminating the communications one from the other by using different inter-terminal potential differences.

Description

Technical field [0001] This application claims the priority of Japanese Patent Application No. 2008-180997 filed on July 11, 2008, and the disclosure content is incorporated by reference in its entirety. [0002] The present invention relates to a liquid container, a liquid ejecting device, and a liquid ejecting system, and more particularly to a liquid container having a plurality of electrical equipment, a liquid ejecting device using the liquid container, and a liquid ejecting system containing the liquid container. Background technique [0003] In order to supply the ejected liquid to liquid ejecting devices such as inkjet printers, a liquid container containing the liquid is used. [0004] Conventionally, as a method for managing the remaining amount of liquid in a liquid container, a method in which a liquid ejecting device cumulatively calculates and manages the amount of ejected liquid through software; and a method in which a liquid remaining amount sensor is installed in th...
