Abstract
A hand held device for spraying liquid utilizes insertable drop-on-demand ink jet cartridges. The disclosed device is simple and inexpensive in design and facilitates interchangeable use of different inks without intervening cleaning.
Claims2
A hand-held ink jet device constructed for use with insertable ink jet print/cartridges to produce ink droplet streams for stroke-marking, said device comprising:
- (a) nest means for insertably receiving an ink jet print/cartridge of the type having a self-contained ink supply, a plurality of orifice means and a plurality of discrete jetting means energizable respectively for drop-on-demand ejection of ink droplets through such orifice means;
- (b) driver means including a plurality of discrete drivers for respective coupling to said plurality of discrete print/cartridge jetting means, said drivers being selectively actuatable for providing ink jetting electrical energy pulses;
- (c) means for electrically coupling said driver means to the jetting means of a print/cartridge inserted in said nest means;
- and
- (d) switchable control means for selectively actuating said driver means to provide electrical energy pulses in a continuous series and for selectively controlling different numbers of driver means to energize their respective jetting means with such continuous pulse series.
