Abstract: PURPOSE: A method for processing events having a hierarchical structure in a communication equipment is provided to rapidly inform an operator of the state of the data transmitted by a communication equipment in real time. CONSTITUTION: A communication equipment reads all event information(41). The equipment initializes a variable E to 1(42). The equipment checks whether the 1st event occurred actually(43). If the 1st event didn't occur, the equipment checks whether the variable E is larger than 7(50). If the variable E is smaller than or equal to 7, the equipment increases the variable E by 1(51) and returns to step 43. Then, if it is confirmed that the 2nd event occurred actually, the equipment checks whether the 2nd event is the uppermost event(44). As the 2nd event is not the uppermost event, the equipment checks which event is the upper event of the 2nd event(45). The equipment confirms whether the upper event of the 2nd event occurred actually(46). The equipment confirms whether the 1st event is the uppermost event(48). The equipment checks whether the 1st event occurred(49). As the 1st event didn't occur, the equipment returns to step 50, recognizes that the variable E is smaller than 7, increases the variable E by 1, and returns to step 43 again.

CONSTITUTION: A printer and an ink tank(1) for the printer capable of precisely detecting that ink has run out in a foam type ink tank. The ink chamber(30) and an ink passage are formed in this order between a foam containing portion(6) and the ink outlet of a foam-type ink tank. A first filter(11) is installed between the foam containing portion and the ink passage and used to pass bubbles through, whereas a second filter(12) having a pore diameter smaller than the pore diameter of the first filter is installed between the ink chamber and the ink passage. A rectangular prism for detecting an ink end is formed on the side of the ink chamber(30). When the reflective surface of the rectangular prism is exposed from an ink liquid level as bubbles are gathered in the ink chamber with ink that is running short, light is reflected from the reflective surfaces and is detected by a reflection type optical sensor on the ink-jet printer side. Thereby, the ink end is determined. When the capacity of the ink chamber is set sufficiently smaller, the ink end is detectable at a point of time when the ink has substantially run out.
