PURPOSE:To improve operability with an easy reading of results of indication by outputting number or single weight as set through a proper display section among a piece-number display and a single weight display with the switching of a circuit according to an operation mode. CONSTITUTION:With the operation of a single weight setting key 20, an output is inverted to H and held while a gate 21 for switching a display data over to a single display 14 turns on a gate 22 under the operation of the single weight setting key 20 and a single weight written into a key-in register 5 through a ten-numeric key 6 is indicated on a single weight display 14 through the gates 22 and 24. With the operation of single weight setting key 20, a switching signal of a gate circuit 16 goes to H through an OR gate 25 so that an output of a subtractor 3 is supplied to a number display 15 through gates 17 and 19. Thus, as gates 16 and 21 are switched by the operation of the single weight setting key 20, in the second operation mode, data being keyed-in is indicated on the signal weight display 14 thereby facilitating the reading of results of the indication. |
