Abstract

PURPOSE: To simplify key operations to perform operations efficiently, by causing a flip flop to send a multiplication command to an operation circuit to make multiplication possible even if no multiplication command key is depressed.
CONSTITUTION: In the electronic desk calculator where multiplication can be operated, operation circuit 6 not only stores the numeric input, etc., from keyboard 3 but also receives operation command signals outputted from control part 4 according to the set state of FF5 and keyboard 3 to execute various operations. The operation result is sent to buffer 2 for display through control part 4 and is displayed on display unit 1. In this case, FF5 sends the multiplication command to circuit 6 to execute multiplication even if no multiplication command key is depressed, so that key operations can be simplified to execute operations efficiently.
