Problems solved by technology

[0002] Known printing (PRINT) type calculator is as shown in Figure 7, mainly is that a small-sized printer 71 is set on the calculator body, to print any calculation formula and the result of typing in at present, so that the user can know and Confirm what keys you type or what the answer is, and you can use the printed output as a report for your own reference or as a receipt; but if this report is needed repeatedly, the known print-type calculator cannot automatically print out the same report, and the user must repeatedly key in the previous calculation formula and calculated results to obtain another same report, which is obviously inconvenient and it is difficult to ensure that there will be no errors when typing again. Therefore, the aforementioned printing It is necessary to improve the type calculator

Embodiment Construction

[0021] Regarding the preferred embodiment of the printing type calculator of the present invention, please refer to the hardware block diagram shown in Fig. , memory 14, print driver 15, printer 16, and LCD display 17 and other components, wherein, under the general use state, the user is to key in calculation data by the input button group 11 and display it on the LCD display 17 at the same time. After the calculation and processing by the microprocessor 13 , the obtained result is output to the LCD display screen 17 .

[0022] In the print mode, the microprocessor 13 drives the printer 16 through the print driver 15 to print the data entered by the user and the processed results.

[0023] The memory 14 is for the microprocessor 13 to store the data and / or processing results entered by the user, and the user can use the operation of the up key 111 and the down key 112 in the input key group 11 to These data stored in the memory 14 are scrolled on the LCD display screen 17 so...

Abstract

A array printing computer for duplication array prints of report forms is to key in the information with a group of input keys, to use a display screen for display the keyed in information and the processed results, a report form printer for printing the keyed in information and processed results out in array, a storage for storing the information and processed results, a micro processor for processing the information and controlling the display screen. The action of the report form printer and storage together with micro processor with allow the information and the precessed results to be displayed on the display screen for checking and revising or for duplication array printing to let the user conveniently print out the desired report form in array type with the computer.
