Electronic price calculating weighing machine - has switch in front of computer, with two actuators for input operation

摘要

The price registering weighing machine has a memory for preset unit prices of goods and an input stage with a keyboard. The latter is used for recall of a respective price from the memory, or for input of an independent goods price. A computer is used to form the price of the sale. A display indicates the prices and/or weights. In front of the computer is connected a two position switch. In its first position the switch couples the computer to the memory, while in its second position it provides direct connection to the input stage. The switch has two sequentially arranged actuators, one for holding the switch in one of its two positions, while the other one brings the switch into its input stage connecting position. Preferably a signal indicator is associated to the actuators.
