THREE-DIMENSIONAL SEMICONDUCTOR ELEMENT, INK TANK WITH THIS ELEMENT ARRANGED THEREIN, INK JET RECORDING DEVICE EQUIPPED WITH THIS TANK, AND COMMUNICATION SYSTEM USING THIS THREE-DIMENSIONAL SEMICONDUCTOR ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional semiconductor element or the like capable of detecting the detailed information within an ink tank of each color in real time and performing a two-way communication for the information with an external ink jet recording device. SOLUTION: This ink jet recording device 600 comprises a liquid discharge head (not shown) for discharging an ink drop for printing and a carriage 607 for loading the color ink tank 500 for each color retaining the liquid supplied to the liquid discharge head. As the ink tank 500, tanks of four colors (B, C, M and Y) are loaded. A three-dimensional semiconductor element 11 having a communication function having a different responding condition is arranged on each of the ink tanks so as to be communicatable with the communication circuit 150 of the ink jet recording device 600 arranged out of the ink tanks 500. The three-dimensional semiconductor element 11 is constituted so as to be communicatable by the resonance by electromagnetic induction of a resonance circuit 102.
