A customer of an eating house orders refreshments by pressing a first touch panel provided at a customer's seat, watching a liquid-crystal monitor on which a menu of the refreshment and an average cooking time thereof are displayed. A cook inputs cooking-state information with a second touch panel provided in a kitchen when cooking is started and is completed. The cooking-state information is displayed on the liquid-crystal monitor so that it is possible to confirm a cooking state of the ordered refreshment. When the ordered refreshment is untouched, the customer can cancel or urge the refreshment by pressing the first touch panel. Upon instructing a check with the first touch panel, the check is printed out from a printer. The customer can order, cancel and urge the refreshments without calling a waitperson.

Information administering system for an eating house

A cartridge is set in a printer main unit, and has a remaining toner measurer which measures toner in a toner chamber upon setting of the cartridge. A cartridge memory stores information of a remaining toner amount measured previously. CPU compares the remaining toner amount measured newly with the remaining toner amount measured previously and read from the cartridge memory. If there is an increase in the toner, the cartridge is determined as improper cartridge reloaded with the toner. An alarm signal is generated. Also, printing is inhibited. In another preferred embodiment, shortage information is assigned to the cartridge upon using up the toner. The cartridge, if it has the shortage information, is determined as improper. If a characteristic of the toner is not within a reference range, the cartridge is determined improper. In another preferred embodiment, an upper limit of the number of times of toner reloading is predetermined. The cartridge is determined improper if the reloading time number comes up to the upper limit. The improper cartridge is set in a state in which operation is inhibited. Also, when the cartridge is disassembled, the improper cartridge is inhibited from operating.
