Abstract

PURPOSE:To improve discharge efficiency as well as stability of ink drop by preventing from entering dust and air, by integrally forming a head and a tank and by providing a ventilating means in order to equalize the pressure in the tank to the atmospheric pressure. CONSTITUTION:An ink jet head is accommodated in a head accommodation section 2 of a box 1. A supply tube 5 is connected to the end of a glass nozzle 4 in the head, while the other end of the supply tube 5 passes through a bulkhead 6 between the head accommodation section 2 and an ink reservoir 3, and extends as far as the bottom of the reservoir 3. Next, the supply tube 5 is airtightly sealed to the bulkhead 6. Then, an air hole 8 is made to the bulkhead 6 between the reservoir 3 and head accommodation section 2 in order to equalize the pressure in the reservoir 3 to the atmospheric pressure. A diameter of the hole 8 of 10mm or less is recommended.
