Abstract

PURPOSE: To make it possible to omit a part of calculation processings, which the operator executes directly conventionally, and the recognition process of values of numbers, by incorporating a calculation processing function in an abacus and by giving a digital display mechanism.
CONSTITUTION: Digital display plate 3 is fitted onto an abacus, and data processing unit 5 dependent upon electronic parts is incorporated in the abacus, and a digital number of the same value as the position of counter 1 is displayed on the abacus. Counter 6 of a part of the abacus is used as a switch for calculation to perform the function of an operating switch. An electronic circuit having a memory function is incorporated in the abacus to perform complicated functional calculation. Further, the abacus is connected to an external large-scale computer to give a function as an I/O device to the abacus.
