Description

[Detailed Description of the Invention] The present invention relates to an improvement of an office computer, and in particular, it equips a conventionally well-known office computer with an arithmetic device (such as a calculator) that is not directly related to the office computer. The keyboard input device used as a method can be switched between the office computer and the arithmetic unit, so that local calculations can be performed using the same input device without interfering with the processing of the office computer. This is intended to improve the operator's work efficiency.

Conventionally, office computers have been used as follows: 1. A calculation device such as a calculator that is not directly related to the office computer is provided separately from the office computer, and the calculation device is provided with an input device such as a dedicated keyboard.

2. Add computing power to office computers,
The office computer also performs calculations.

etc. are known.

However, as in 1 above, if calculations etc. are performed on a separate calculator, the operator will have to perform two types of input operations, or it will be inconvenient if the calculator is not nearby. When calculations and the like are performed by an office computer, there are drawbacks such as an increase in the load on the office computer and an increase in the processing time required by the office computer.

The present invention was made to solve the above-mentioned drawbacks of the conventional technology, and allows calculations to be performed on a local device such as a calculator using the same input device without interfering with the processing of the office computer. Make your office computer even easier to use,
The aim is to improve the work efficiency of operators.

FIG. 1 is a block diagram for explaining an embodiment of an office computer according to the present invention.
is the main body of an office computer or the like, 2 is an input device such as a keyboard, 3 is a switching gate, 4 is an arithmetic device such as a calculator, 5 is a switching gate circuit, 6 is a display device, 7 is a switching switch, and switching gate 3 is The changeover switch 7 selects and switches between inputting the key information from the input device 2 into the office computer main body 1 or the arithmetic device 4, and the changeover gate circuit 5 selects and switches the inputting of the key information from the input device 2 to the office computer main body 1 or into the arithmetic device 4. It is possible to select and switch between supplying from the office computer main body 1 and supplying from the arithmetic unit 4. Note that FIG. 2 is a diagram showing an example of the arrangement of the input device 2, display device 6, and changeover switch 7. Normally, the changeover switch 7 is turned on to the system (office computer) side, and the key information from the input device 2 is supplied to the office computer main body 1 through the passage 3a of the changeover gate 3, and the office computer main body 1 performs the original processing, such as a printer. During this process, the operator is left blank. The operator uses this wasted time to perform subtotals, inspections, etc. of the slips, but in doing so, conventional office computers have the drawbacks mentioned above. In contrast, according to the present invention, when the changeover switch 7 is turned on to the calculator side while the office computer is performing processing work, the key information from the input device 2 is transferred to the calculation device through the passage 3b of the changeover gate 3. 4, it is possible to operate the arithmetic unit 4 without preventing the processing of the office computer main body 1, and it is possible to perform subtotals and inspections of slips etc. while the office computer is processing. Can be done.

FIG. 3 is a detailed view of the switch section. As mentioned above, information from the keyboard 2 is normally transferred to the office computer main body 1 through the switch 7.
The main unit performs tasks such as printing out the slips to the printer, while the operator uses the blank time to perform subtotals and inspections of the slips, etc. In order to do this, when the switch 7 is turned to the calculator side, the information from the keyboard 2 is switched so that it is input to the arithmetic unit 4,
At the same time, the calculator instruction LED lights up. Therefore,
At this time, the information from the keyboard 2 does not go to the office computer main body 1, does not interfere with the operation of the office computer main body 1, and the LED for instructing the calculator lights up, prompting the operator to select either the calculator mode or the office computer mode. make it even easier to understand.

Note that the above is only one embodiment of the present invention, and for example, by providing the arithmetic device 4 with a clock function, the display device 6 is normally set to the clock display, and only when the arithmetic device is in use. The calculation may be displayed. In addition, there are cases where you want to use a calculator simply as a calculator, and cases where you want to input the calculated results into an office computer.In the latter case, it is also possible to input the contents displayed on the display device into the office computer. To do this, after operating the calculator, the displayed data should be input to the office computer when the changeover switch is switched from the calculator side to the system side, while the display remains displayed on the display device. When used as a computer, press the clear key C on the input device (keyboard) to set the display to 0, and then switch the switch to the system side. In that case, the office computer will control the data to be ignored. Just do it.

FIG. 4 is an electrical circuit diagram of the switch section for explaining an example of inputting the results calculated in the calculator mode into the office computer main body 1, and FIG. 5 is an overall block diagram. is a gate circuit, F/F is a flip-flop circuit, and _D1 is a run circuit. After calculating in calculator mode as described above, clearing with clear key C, and then turning changeover switch 7 to the system side, The results calculated in the calculator mode are not input to the office computer main body 1, but before clearing with the clear key C,
When the changeover switch 7 is turned to the system side, the result calculated by the calculator 4 is input to the office computer main body 1 through the changeover gate circuit 5, so that the answer calculated in the calculator mode is immediately input to the office computer main body 1. It can be used for inputting data or simply as a calculator.

Further, it is preferable that the display device has a display means for clearly indicating to the operator whether it is in the calculator mode or the system mode. In that case, for example, a light emitting diode is provided in the upper digit and the light emitting diode is lit When you set the time to calculator mode,
The operator can confirm the input when inputting the calculation result of the calculator. It should be noted that it is easy to understand that the display may be displayed using an underline or the like instead of the light emitting diode. Further, in the above example, the case where the changeover switch 7 is newly provided was explained, but since it is uneconomical to provide a new changeover switch, for example,
If you press the (÷) and (×) keys on the numeric keypad in succession, the system will switch from the system to the calculator.
It is also possible to switch from the calculator to the system when the (+) and (-) keys are pressed in succession, and if you switch the key input like this without providing a switch, This is more effective when displaying a mode on a display device.

FIG. 6 is a principal electrical circuit diagram for explaining an example of a case where switching between calculator mode and system mode can be performed without using the changeover switch 7, and FIG. 7 is an overall block diagram. in,
In the figure, F/F is a flip-flop circuit, G is a gate circuit, and Dr is a driver circuit. For example,
If you press the “×” key after pressing the “÷” key without pressing any other keys, it will enter calculator mode.
When the "+" key and "-" key are pressed consecutively, the system mode is entered.

As is clear from the above description, according to the present invention, it is possible to perform calculations etc. using the same input device without interfering with the processing of the office computer, and the work efficiency of the operator can be significantly improved.
