Abacus for accounting calculation and with luminescent prompting beads

Abstract

The invention discloses an abacus for accounting calculation and with luminescent prompting beads, and belongs to the technical field of accounting. The abacus consists of a peripheral frame (1), a partitioning frame (2), bead stringing shafts (3), the luminescent prompting beads (4) and a switch (5). The abacus is characterized in that the bead stringing shafts (3) are brackets for supporting theluminescent prompting beads (4) and with an internal circuit element for controlling the luminescence of the luminescent prompting beads (4), and are totally 9-13 in number; the luminescent promptingbeads (4) are shaped like known abacus beads, are made of glass or plastic, are respectively in a shape of a cake with a middle hole, and are totally 7 in number on each bead stringing shaft (3), i.e., 2 above the partitioning frame (2) and 5 below the partitioning frame (2), luminescent lamps (6) are arranged at the centers of the inner parts of luminescent prompting bead bodies (9) above the luminescent lamps (6) and are known LED (Light Emitting Diode) lamps. The abacus disclosed by the invention is simple to manufacture, strong in operability, and low-cost, and has an obvious effect.

Description

technical field [0001] The invention relates to an abacus for accounting calculation with luminous prompt beads, belonging to the technical field of accounting. Background technique [0002] The abacus is a simple calculation tool invented by the ancient Chinese working people. China is the hometown of abacus. Today, when computers are widely used, the ancient abacus is not only not abandoned, but is in the ascendant in many countries due to its advantages such as flexibility and accuracy. The abacus allows children to quickly and accurately calculate the required calculation results. Existing abacuses come in different shapes and materials. The general abacus is mostly made of wood or plastic. The abacus is composed of a series of beads of equal number arranged in a rectangular wooden frame. There is a beam to divide the beads into two parts, the bead runs through a straight column, commonly known as "file" ”, usually 9th, 11th or 13th gear. There is a beam in the middl...

Problems solved by technology

[0003] In order to overcome the problem that the traditional abacus cannot remind the operator which bead has moved, which one has not moved, and whether the movement is in place through light emission after the abacus beads move, the present invention provides an abacus for accounting calculation with light-emitting reminder beads. The abacus for accounting calculation of the reminder beads uses the operator to press and rotate the switch shaft, the movable pole and the fixed pole are in close contact, connect the movable pole power line and the fixed pole power line together, and then toggle the luminous prompt bead, Make the luminous reminder bea
