PROBLEM TO BE SOLVED: To make easily distinguishable the attaching-detaching state of a cartridge, attaching-detaching date and time, and the kind of an injection liquid within a cartridge by providing a means for memorizing date and time of attaching-detaching the cartridge, the kind of the cartridge resulted from detecting the shape of the cartridge, and the kind of an injection liquid. SOLUTION: When the cartridge 1 for filling an injection liquid is assembled into a main body 3 by a cartridge holder 2, a switch 6 is pushed up to turn on. A microprocessor, which provides a data memory, a log memory, a calendar, and a timepiece on a base plate 14, reads a state of a switch 7 and compares contents of a memory 9 storing a kind of the cartridge and a kind of the injection with a comparator 8a according to a state of the switch 7 to obtain the kind of the cartridge 1 and the kind of the injection liquid. The date and time of assembling the cartridge 1 can be further obtained. Data of the date and time are stored in the log memory 12 and the stored data can be displayed on a display section 13. |
