Abstract

PURPOSE:To prevent a computed result or a memory content after being switched to the computed result from being erased accidentally by providing two display parts, and performing the simultaneous display of an arithmetic operation or the computed result and a memory at the time of displaying the memory content. CONSTITUTION:By providing the two display parts 17 and 18, the display part on one side is used in an ordinary operation, and at the time of displaying the content of the memory 14, display is performed on the display part on the other side. Therefore, it is possible not only to perform another arithmetic operation even when displaying the content of the memory 14, but to observe the computed result and the content of the memory 14 simultaneously since the two display parts 17 and 18 can be used. In such a way, it is not feared that the computed result is erased accidentally, and also, it is possible to perform the comparison of data intended to compare with the computed result by storing the data in the memory 14 easily since both data are displayed simultaneously.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、電子式卓上計算機の表示形態に関するもので

〔従来の技術〕[Conventional technology]

従来、この種の電子式卓上計算機ではメモリの内容を演
算中に表示するこが出来ない為、演算終了後表示してい
た。又、メモリの内容を表示する時、現在表示中の演算
結果とメモリの内容を交換しなければ表示することがで
きなかった。Conventionally, in this type of electronic desktop calculator, the contents of the memory cannot be displayed during calculation, so the contents are displayed after the calculation is completed. Furthermore, when displaying the contents of the memory, it is necessary to exchange the currently displayed calculation result with the contents of the memory.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

内容を消してしまうという欠点があった。In the above-mentioned conventional electronic desktop calculator, the contents of the memory can only be displayed after one calculation has been completed. Also, when trying to display the contents of memory,
Since the calculation result and the memory contents cannot be displayed at the same time, the calculation result and the memory contents must be exchanged and displayed, so there is a risk of accidentally erasing the calculation result or the memory contents after the exchange. There were drawbacks.

〔問題点を解決するための手段〕[Means for solving problems]

本発明の電子式卓上計算機は、メモリの内容を表示して

る。The electronic desktop calculator of the present invention has two display sections in order to perform calculations while displaying the contents of the memory, and to display the contents of the memory at the same time as the calculation results.

〔実施例〕〔Example〕

次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

様の演算を行うことができる。In the case of normal numerical input and calculation, data is first inputted from the key human power section 11 shown in FIG. After being transferred to 16, it is displayed on display unit 18. Next, when transferring the calculation result to the memory 14, by pressing a specific key for transfer from the key control unit 11, the control unit 12 decodes it as a transfer command to transfer the calculation result to the memory 14, and the result is transferred to the memory 14. be transferred. Displaying the contents of the memory 14 on the display section 17 is done by pressing a specific key from the key control section 11, which is interpreted by the control section 12 as a command to display the contents of the memory, and after the data in the memory 14 is transferred to the display drive circuit 15. , are displayed on the display section 17. If a specific key for displaying the contents of the memory on the display section 17 is not pressed by the key human power section 11, the display drive circuit 1 is sent to the control section 12.
Issue an order not to display it to 5. Finally, display section 17.
18 are independent from each other, so even when the display unit 17 is displaying the next value, if an instruction to calculate the next value is input from the key input unit 11, the calculation unit 13 calculates it, and the calculation result is transferred to the display drive circuit 16. , are displayed on the display section 18, and by transferring the contents of the memory 14 to the arithmetic section 13, the same arithmetic operations as in the conventional art can be performed.

Not only can other calculations be performed even while the contents of the screen are being displayed, but since two display sections are used, the calculation results and the contents of the memory can be viewed at the same time, so there is no need to worry about accidentally erasing the calculation results. Furthermore, if the data to be compared is stored in the memory, it is easier to compare the data with the calculation results because both data are displayed simultaneously.
