Disclosed herein is a thin film cell in which a cell unit is sealed by a polyimide film. Such a cell unit can be obtained by forming an ion-conductive polymer electrolytic layer formed by mixing polyethylene oxide derivatives with lithium salt on a negative-polarity material composed of lithium or a lithium-aluminum metal foil and then forming a layer of a positive-polarity material from composite materials formed by mixing Vanadium oxide and polyethylene oxide derivatives together, on the electrolytic layer, by using a screen printing process. Also disclosed is a printed circuit board with a thin film cell incorporated therein, in which said cell unit is to be mounted on a flexible film substrate, by using a screen printing process. By this invention, the thin film cell and the printed circuit board can be fabricated in a continuous manner by making use of a screen printing process.

Printed circuit board having a thin film cell incorporated therein

An equipment which requires an external unit to be assembled therein for starting inherent operation. The equipment includes a detection means for detecting an identification mark such as a trade mark affixed to the external unit. The equipment is only operable upon detection of a proper identification mark. The equipment may be a printer and an image recording apparatus such as a copying machine, and the external unit may be an image recording medium cassette such as an ink ribbon cassette and a rolled photosensitive sheet cartridge.
