A liquid ejecting apparatus includes: a head having a nozzle; a pressure-changing unit for changing pressure of liquid in the nozzle in such a manner that the liquid is ejected from the nozzle; a level-data setting unit for setting a selected level data from a plurality of level data, based on an ejecting data; a driving-signal generator for generating a first driving signal and a second driving signal; and a driving-pulse generator for generating a driving pulse based on the selected level data and the first driving signal and the second driving signal. The first driving signal and the second driving signal are periodical signals having a same period. The first driving signal includes a first large-drop pulse-wave and a third large-drop pulse-wave. The second driving signal includes a second large-drop pulse-wave. The first large-drop pulse-wave, the second large-drop pulse-wave and the third large-drop pulse-wave have a same waveform, and appear in that order at regular intervals.

A memory includes a nonvolatile memory cell array, and a memory control circuit which carries out writing of data to and reading of data from the memory cell array in access units of N bits where N is an integer equal to 2 or greater. The memory cell array includes a rewritable area in which both writing of data and reading of data are permissible, and a read-only area in which writing of data is prohibited and reading of data is permissible. The rewritable area is configured so that the N bits constituting one access unit contain both actual data and an error detection code. The read-only area is divided between an actual data area in which the N bits constituting one access unit contain actual data, and an error detection code area in which the N bits constituting one access unit contain error detection codes.

A circuit board of an ink cartridge is provided with a plurality of terminals, with the contact portions of the plurality of terminals forming a plurality of lines. The contact portions of two terminals used for detecting installation are positioned in a first line, and the contact portion of a power terminal is positioned between the two terminals. The first line may be positioned to a leading side when the ink cartridge is moved in a prescribed direction to effect installation in a printer. Alternatively, the first line may be the line closest to an opening of an ink delivery port. Alternatively, the first line may be the line closest to an ink delivery needle.

An ink cartridge 111 holding a recording material used for printing therein has a sensor substitute module 170 to simulate operations of a cartridge having a built-in sensor. As a control circuit 222 of a printer 200 gives a sensor access instruction to the ink cartridge 111, the sensor substitute module 170 generates a specific signal and outputs the specific signal via an output module 178. The specified signal is equivalent to a signal that represents a sufficient level of remaining ink and is expected to be output from the built-in sensor of the cartridge. The ink cartridge 111 is thus applicable to both a printer designed for the use of a cartridge with a built-in sensor and a printer designed for the use of a cartridge without a built-in sensor. Namely the cartridge of the invention is compatible with the cartridge having the built-in sensor.
