摘要

In an ink container (100) of the invention, an electric power generator (240) rectifies a carrier wave transmitted from a printer PT and thereby generates an electric power for driving a controller (210) and an RF circuit (200). A program voltage generator (250) and a sensor driving voltage generator (260) are connected in series with the electric power generator (240) to individually generate a program voltage required for writing data into an EEPROM (220) and a voltage required for driving a sensor SS including a piezoelectric element. The arrangement of the invention efficiently generates electric powers, which are to be supplied to respective constituents of a container for a printing material, such as the ink container (100), which establishes communication with a printing device, such as the printer (PT), from a preset electric power generated by utilizing a radio wave.
