【発明の名称】貯蔵容器中の導電性書き込み液の貯蔵量を監視する装置
Document Type and Number:
Japanese Patent JPH0827206
Kind Code:
B2
Abstract:
Apparatus for monitoring supply of electrically conductive writing fluid in a reservoir for an ink printing device which has three electrodes with one pair of the electrodes mounted in a region of the reservoir which is constantly moistened by the writing fluid and provides a first signal which produces a fluid comparison resistance. An additional electrode together with one of the pair of electrodes produces a signal which indicates the change of resistance as a function of the fluid level of the fluid. A control electronics component receives the first and second signals and supplies an output to a shutoff device. A generator and an inverter which receives an input from the generator supply pulses to two of the electrodes.
