Abstract

加1算盘是一种计算用具，主要内容是在算盘的下梁(2)底部开有使装有算珠(1)的滑动装置(4)固定在下梁(2)上并能滑动的滑动槽(3)。具有结构简单，提高算盘计算速度特点。

Description

加1算盘
加1算盘是一种计算用具
目前，人们广泛使用的算盘是上档一珠，下档四珠的结构，虽有二元示数的功能(即在算盘上拔珠靠梁表示一个数时，靠框的算珠也能表示另一个数)但并不完整，人们常用的是用靠梁的算珠表示要计算的数字，而靠框的算珠没有什么意义，即使是在上一下四的五珠算盘上，有的收款人员在用靠框的算珠时，也要默记把末档靠框的算珠加1，而把以后靠框均为9的各档看成零。这样不能充分显示算盘的二元示数的功能，即使显示了也要经过长时间的锻炼并且容易发生差错。另外，梁上三位一隔的记位点，没有明显的个位档。
本发明的目的在于提供一种加1算盘，提高收款速度，易于确是定位档，解决了收款人员在给顾客找钱时要用减法计算或暗记在末档框珠加1，用加1算盘只需把加1算珠移到末档，一看外珠即可得到应找给顾客的钱数，另外一般计算时，将加1算珠与梁上任意一个记位点对应，用于定位，可做个位档，在计算时不会忘记个位档的发生串位现象，默记个位档。
本实用新型加1算盘的具体内容是，在算盘的下梁(2)底部开有滑动沟槽(3)，使有算珠(1)滑动装置(4)固定在下梁(2)并能沿滑动槽(3)滑动。
最佳实施例：图1装配示意图、图2滑动装置示意图
结合附图、进一步说明，将算盘的下梁(2)底部开上一条可以使带有算珠(1)的滑动装置(4)能顺下梁2滑动和起固定作用的滑动沟槽(3)
