CONTAINER FOR PRINT MATERIAL, DEVICE FOR DETECTING CONCERNING PRINT MATERIAL IN CONTAINER, AND METHOD FOR COMMUNICATING INFORMATION BETWEEN CONTAINER AND PRINTER

摘要

PROBLEM TO BE SOLVED: To obtain a container for print material communicating with a printer in which power being fed to each component can be produced from a power generated using an electromagnetic wave. SOLUTION: An ink container 100 generates a power for driving a control section 210, an RF circuit 200, or the like, by rectifying carriers transmitted from a printer PT at a power generating section 240. Since a program voltage generating section 250 and a sensor driving voltage generating section 260 are connected in parallel at the power generating section 240, a program voltage required for writing data into an EEPROM 220 and a voltage for driving a sensor SS employing a piezoelectric element are generated individually.
