Abstract

本实用新型涉及一种双梁六珠算盘,其特征是该 算盘具有上、下两根横梁,每根档杆被上、下横梁分隔 为三部分,上横梁以上的档杆上串有一个算珠,下横 梁以下的档杆上串有一个算珠,上、下横梁之间的档 杆上串有4个算珠。其优点是除可进行普通算盘的 计算外,还可进行补数计算,并简化了一些复杂的减、 乘、除法运算,还可用于十二、十六、六十进位制的计 算。

Description

本实用新型是一种计算工具。
算盘是一种古老的计算工具,现在使用的算盘主要有两种,一种是单梁六珠,一种是单梁七珠,由于结构简单,使用方便,因而在电子计算器广泛普及的今天,仍受到广大财务人员的青睐。但现有算盘的功能较为单一,只能分步逐一进行四则和开方、乘方运算,在运算中还存在珠不够用和定位不方便等缺点。
本实用新型的目的在于解决目前算盘存在的缺点,增加算盘的计算功能。
本实用新型提出的算盘包括框架、横梁、档杆和算珠,所述的横梁为上、下两根,串有算珠的档杆被两根横梁分隔为三部分,上梁以上部分有一个算珠,下梁以下部分有一个算珠,上下梁之间有四个算珠,档杆可根据需要制成十三到二十七档不等。新型双梁六珠算盘除了可以利用上部五珠进行普通算盘的计算外,还可进行一系列其它功能计算。例如进行补数计算,拨珠靠上梁表示实数,珠靠下梁表示补数,这种计算对商店售货员找零计算非常便利。还可利用此算盘作减、乘、除法的简捷运算,并可用于十二、十六、六十进位制的计算,最下面的算珠可用作定位或分项的标记。
本实用新型提出的新型算盘弥补了原有算盘功能的不足,使一些复杂的运算变得简捷、迅速。
图1是本实用新型的结构示意图。
图2是本实用新型的一个演算实例。
实施例:参见图1,本实用新型的双梁六珠算盘由框架1、档杆2、横梁3、4和算珠5组成。档杆2为13档,横梁3上部的档杆2上有一个算珠5,横梁4下部的档杆2上也有一个算珠5,横梁3和4之间的档杆2上有4个算珠5。图2为本实用新型的一个计算实例,某人用10元面额的人民币购物,三件物品价格分别为1.13元、2.11元、5.03元,累计8.27元,用上部五珠进行加法计算后,在无上珠靠上梁的档位拨一下珠5靠下横梁4,这样靠下横梁的数便为应找回的余额1.73元(末档位加一),既免去反减的麻烦,又准确无误。
