    • An answer totaling and analyzing apparatus according to the present invention possesses an auxiliary light-projecting and receiving unit relaying a light-emitting and reception between a center unit and answer units, in addition to the center unit and the answer units exchanging signals by optical pulses. The center unit assigns answer periods of the respective answer units by answer command signals for the plural answer units. The respective answer units can reply answers for questions with a very small number of pulses by using a method in which contents of the answer are represented by a time position of an optical pulse transmission in the answer period assigned to the answer unit. The center unit discriminates the answer signals from the respective answer units by this communication method and detects the answer and totalizes and analyzes the answer. The light-emitting and receptions between the answer units and the center unit are relayed by using the auxiliary light-projecting and receiving unit, and thereby, it becomes possible to use in a large meeting room and to use a much number of answer units which are conventionally difficult, and a simple and stable answer totalizing and analyzing can be performed.
    • 根据本发明的答案总计和分析装置除了中心单元和应答单元通过光脉冲交换信号之外,还具有中继单元和应答单元之间的发光和接收的辅助投光和接收单元 。 中心单元通过多个应答单元的应答命令信号分配各个应答单元的应答周期。 通过使用其中回答内容由分配给应答单元的应答周期中的光脉冲传输的时间位置来表示的方法,各个应答单元可以回答具有非常少量脉冲的问题的答案。 中心单元通过该通信方法来区分来自各个应答单元的应答信号,并检测答案并对其进行总结和分析。 应用单元和中央单元之间的发光和接收通过使用辅助投光和接收单元进行中继,从而可以在大型会议室中使用并且使用大量的应答单元 通常是困难的,并且可以执行简单和稳定的答案总计和分析。

    • A course guidance system includes a direction sensor and a speed sensor both fitted to a moving body, a display mounted in the moving body and a map displayed in a manner corresponding to the display surface of the display and in which the present position of the moving body is derived by the direction sensor and the speed sensor and is plotted on the display in a manner corresponding to the map. The improvement comprises a locus memory for sequentially storing an X component value and a Y component value of the driving position based on a predetermined driving distance obtained from the speed sensor and on the driving position obtained from the direction sensor, a locus display memory for storing data in a manner corresponding to the display surface of the display, the data being obtained by reading the contents of the locus memory in a manner corresponding to the scale of reduction of the map, and a display for plotting the driving locus of the moving body on the display surface based on the contents of the locus display memory, wherein the data to be read when the contents of the locus memory is transferred to the locus display memory are divided into a plurality of groups each consisting of a data line to be read at a predetermined interval which are sequentially read and transferred, and the plotted line of the driving locus to be displayed is displayed sequentially and progressively from a rough display to a dense display.
