Abstract

亮珠算盘的结构如图1所示。它由边框、挡板、珠杆、亮珠和电池组成。边框、挡板、珠杆均由金属制成。边框与珠杆与电池的负极连接。挡板与电池的正极连接。在挡板与边框和珠杆之间有绝缘层。当亮珠接触金属挡板时,亮珠发光。亮珠由半透光外壳、金属滑套、绝缘套、带磁性的金属版和发光体组成。本发明的优点:(1)在用珠发光,备用珠不发光,便于读数;(2)基本取消虚拨现象。

Description

亮珠算盘
珠算作为一种方便、简单、实用的计算工具已有相当长的历史。虽然现在已经发明了计算机、计算器并广泛应用在科学、教育、金融、会计及家庭等各个领域。但珠算这一传统计算工具在各方面还有广泛应用，特别是它的开发儿童智力的功能是计算器所不能取代的。
传统的算盘有各种各样，但(1)由于在用珠与备用珠颜色一样，都有一个读数不太方便的问题，特别是当算盘较小，在用珠与备用珠间隙较小时更不方便；(2)在用珠虚拨，会造成计算错误。
本发明(1)利用电发光使在用珠变成彩色，便于读数；(2)利用带有磁性的算珠，避免或减少虚拨。
亮珠算盘的结构如图1所示。它由边框、挡板、珠杆、亮珠和电池组成。边框、挡板、珠杆均由金属制成。边框与珠杆与电池的负极连接。挡板与电池的正极连接。在挡板与边框和珠杆之间有绝缘层。当亮珠接触金属挡板时，亮珠发光。
亮珠的结构如图2所示。它由半透光外壳、金属滑套、绝缘套、带磁性的金属版和发光体组成。
本发明的优点：(1)在用珠发光，备用珠不发光，便于读数；(2)基本取消虚拨现象。

Claims (2)

1.亮珠算盘的结构原理通过电流使在用珠发光或改变颜色，便于阅读；通过磁力减少或取消珠子虚拨现象。
2.亮珠的结构亮珠由半透光外壳、金属滑套、绝缘套、带磁性的金属版和发光体组成。
