Description

[Detailed Description of the Invention] The present invention relates to an electronic computer with a clock that has both a clock function and a calculator function, and particularly aims to make effective use of the display section.

Conventionally, in an electronic computer with a clock, when displaying the day of the week, seven day-of-the-week display segments were provided and these segments were selectively displayed in correspondence with the day of the week.

However, this display was effective only when displaying the clock function and was not used when executing the computer function, resulting in very poor usage efficiency.

The present invention attempts to effectively use the day of the week display segment when executing a calculator function. Specifically, for example, when executing a calculator function, multiple data such as 500+25+35+... are input. When calculating with
This is intended to sequentially light up and display the segments of the day of the week display each time data is input.

An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 is a plan view of the main part explaining the segment configuration of the display section, where SN is the sun-shaped segment that displays numerical values. SD is a dot segment that displays decimal points.

SB is a par segment for displaying the day of the week, and for each par segment SB, a letter W indicating each day of the week is formed on the cabinet CB by printing or the like.

In addition, the display body DSP including each of the above segments is a liquid crystal,
It can be configured with any ECD, LED, etc.

Figure 2 shows the circuit configuration.

CLU is the clock circuit section, CAU is the computer circuit section, SM is the mode changeover switch that switches between the clock function and the computer function.
The DSP is the display described in FIG.

DN is a display drive circuit corresponding to the numerical display section D1 including the sun-shaped segment SN and dot segment SD of the display body DSP, and DB is a display drive circuit corresponding to the bar display section D2 consisting of the per segment SB. It has a data selection function using a mode changeover switch SM.

NK is a group of numerical keys, FK is a group of function keys, C
K is a group of time setting keys for the clock.

When the mode selector switch SM is set to the CL (clock function) side, input to the clock circuit section CLU becomes possible by a predetermined operation of the clock setting key group CK, and the time can be set appropriately as necessary.

On the other hand, at this time, the display drive circuits DN and DB select and input the output from the clock circuit unit CLU, that is, the time information ICL and day of the week information ID, and display them on the display body DSP.

An example of the display is shown in Figure 3, where it is displayed that 0 samurai 2 powder 3 tsui for Tuesday.

When the mode selector switch SM is set to the CA (computer function) side, the computer circuit section CAU accepts the manual input of the numeric key group NK and the function key group FK, and the display drive circuits DN and DB are placed on the computer circuit section CAU side. Now you can select and input the output from .

In this case, the display drive circuit DN corresponding to the numerical display section D1
The input value/calculation value information ICA is input to the bar display section D2, and the data input count information IC is input to the display drive circuit DB corresponding to the other bar display section D2.

Figure 4 shows an example of the display when the calculator function is executed.Here, for example, key operations are performed up to 500 + 25 + 35+, the calculation result 560 is displayed, and three bar segments SB are lit. It is displayed that up to three pieces of data have been input.

Figure 5 shows an example of a counting circuit in the computer circuit unit CAU.The key input signals of the function keys 10, -t, The contents are counted up one by one, and the count contents are reset by a human input signal from the calculation end key or the clear key CL.

CB is a count register in the count circuit CO, from which data input count information ■C is supplied.

OR1 is an OR gate that inputs key human input signals of +, -9×, ÷, and OR2 is an OR gate that inputs key human input signals of = and CL.

Note that the counting circuit is set when a numerical value is input.
, -9×, ÷ function keys may be provided, and the output signal of this detection circuit may be used to count up the count circuit CO (see FIG. 5).

In this case, in the example above, if you input 5 of 500, 1
2 bar segments sB will be lit, when inputting 2 of 25, 2 bar segments will be lit, and when inputting 3 of 35, 3 bar segments SB will be lit.

In any case, the counting circuit can be modified in various ways.

Further, in the above-described embodiment, seven bar segments SB were provided corresponding to the day of the week display, but it is clear that there is no problem even if there are more than this.

As described above, the present invention includes a means for counting the number of input data when executing the calculator function, and also uses at least seven segments used for displaying the day of the week when displaying the clock function, so that the above-mentioned counting contents can be calculated. This segment can be used effectively and the number of input data can be confirmed when executing a computer function, thereby providing a useful electronic computer with a clock.
