DISPLAY FIXING APPARATUS FOR ELECTRONIC DIGITAL DISPLAY SCALE

摘要

PURPOSE:To enable efficient weighing by holding various data such as weight of a load and price as displayed automatically by a specified time when the load is removed from a weighing section to fix a display. CONSTITUTION:When a load is applied to a weighing section 1, an analog signal A is outputted for the load from the weighing section 1 and when it is inputted to an A/D converter 2, a conversion load signal W is inputted into an AND gate 8 from the converter 2. Then, as the load applied to the weighing section 1 becomes stable, a stability signal S turns to a 1 signal and the conversion load signal S applied to the weighing section 1 is outputted from the gate 8 to be stored into a shift register 12. The signal W inputted into the register 12 is shown on a weight display section 15 while being send to an arithmetic section 13, with which 13 a price is calculated and a price signal P is shown on a price display section 16. Then, when the load is removed, a holding circuit is formed to continue a display as a time signal T is the 1 signal in a specified time after the setting of a timer 4. Then, after a specified time, the signal T is down to 0 to release the holding.
