Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic number storage and reading device capable of storing and reading a series of numbers such as telephone numbers.

Conventionally, electronic desktop calculators that can store calculation results, constants, etc. in non-volatile memory using numerical keys have already been proposed, but the display based on the normal numerical lead-in suppresses the upper "0". Therefore, it is impossible to store all key input information in the memory, regardless of the type of operation key, such as "0" before numerical information is input, or symbols related to it. be.

However, remembering phone numbers, name codes,
It is desirable that information such as "0" or a hyphen before numerical information is input, such as the storage of an affiliation code or a patent number, can be stored as is in the memory and output and displayed.

Furthermore, since the telephone number books that each person creates are written in pencil, the font is small and easy to misread, especially in dark places such as at night. Also, when doing office work for each department, name codes are often used, and it is convenient to input and memorize these.

The present invention has been made in view of the above points, and it is possible to increase the memory capacity, specify an arbitrary address, and freely write a series of numbers such as a telephone number to that address using the numeric keys, or vice versa. It is an object of the present invention to provide an electronic number storage/reading device which can specify an address and output and display the number stored at the address and the symbol related thereto.

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

FIG. 1 shows an external perspective view of the main body showing an embodiment of the device of the present invention. Numbers are written according to the capacity of the memory; for example, if there are 100 memories, the numbers are from 1 to 100. 4 is the keyboard part, 0 to 9
is a numeric key, - is a decimal point key, ×, ÷, +, -, = are four arithmetic calculation keys, C is a clear key, CA is a non-volatile memory clear key (described later), NO is a memory address number specification key ( Corresponding to 1 to 100 above), NI is a key for inputting into memory, that is, keys such as 0 to 9, etc., to lead in the desired numerical value, etc., and then, using this NI key, input it to the specified memory with the NO key. do. H, L, P, and U are symbol input keys. TU is a count-up key that starts from 0 when you press this key and counts up the time. TD is a count-up key that counts up the time after entering a numerical value. A countdown key that counts down each time, 5 is a display with each digit in the form of a daily segment, 6 is a mode switch, CL is a calculator mode (TU and TD keys only work in this mode), CK is a clock Display the current time in mode. W is a mode for inputting data to the nonvolatile memory, and R is a mode for outputting data from the nonvolatile memory. 7 automatically turns on when you open the cover 2 with the power switch, and turns off when you close it.
Turn off. Display body 5 is 12 digits here,
Covers display of phone number. FIG. 2 is a diagram showing an example of various displays, for example, a case where a telephone number, time name code, patent number, etc. are displayed.

Storing telephone numbers When storing telephone numbers in memory, a "-" (hyphen) key is provided to distinguish between area code, city code, and number. For example, 0, 6, -, 6,
If you press 2, 1, -, 1, 2, 2, 1, 06-621-1221 will be displayed, and this will be stored in the memory at the first address, for example. Even if the power is turned off, this information is memorized in the memory, so if you turn on the power and call up the first address when you use it, the above display will appear, and if you turn the dial while looking at this, there will be fewer mistakes and you can check it. It's getting easier. If you display numbers in a display type, all you need to do is create a correspondence table between addresses and names. In addition to numbers, the symbol "-" is also stored in the memory, and this is also displayed, which reduces input errors or misreading of station numbers and numbers.

Search for name code The name code and date of joining are memorized and displayed.

(Example) Taro Hayakawa Joined in 1972 Name code 12345 Display 52-12345 Memory of patent (reference) number (Example) Patent reference number 52-857 Display P52-871 Actual case reference number 52-234 Display U52-234 Figure 3 1 is a block diagram showing a specific example of the circuit of the device of the present invention, and shows a case where a telephone number is stored and read. In the figure, MR is non-volatile memory and the others are volatile circuits. Assume that cover 2 is now opened and the power is turned on. memory
The MR has the first address to the 100th address _n1 to _n100 , and each address is composed of 12 digits and 12×4=48 bits, and is, for example, a random access memory. The 12 digits correspond exactly to the display digits. AD is an address decoder, _G1 is an input gate circuit for the memory MR, _G2 is an output gate circuit for the MR, and SHR is a shift register that can essentially store the output of the memory MR as is through the gate _G2 . Here, a method of reading "0" into the memory will be described.

First, memory MR and shift register SHR
is set to clear state by pressing clear key AC. However, in this clear state, a display suppression code SPC is introduced into each memory. Therefore, the digits other than those that are lead-in from the key are suppressed codes, and the digits that are not lead-in are suppressed when displayed on the display device DSP. The lead-in "0" is a 0 code (for example, 0000) and is distinguished from a suppress code, so "0" is displayed as is. Memory write mode W
When you press the AC key, gate g ₁ will be activated while it is pressed.
is turned on and the memory MR address decoder
Circuit to automatically sweep AD from n ₁ → n ₁₀₀
The ADS is activated and the input gate _G1 of each address MR of the memory is turned on in sequence n ₁ → n ₂ → n ₁₀₀ → n ₁ , and the suppress code input through the gate g ₃ is introduced into the memory MR.

On the other hand, since gate g ₂ is also turned on, a clock pulse for shift register SHR is generated, and at the same time, a suppress code is also introduced into shift register SHR via gates g ₃ and g ₅ , and eventually the memories MR,
All digits of SHR become a suppress code. If you input data using the keys in this state, only the digits that are not input will become a suppress code, and that part will be suppressed in the display. Gate _g6 uses V and memory input as a shift register and stores it in memory.
After moving to MR, when the next input is to be made, the signal Sg is used to suppress all contents of the shift register SHR in advance.
is its state signal. (In general calculators, the code 0000 corresponding to 0 is introduced here.) Suppression is processed as described above.

[When in W mode]

If you now press □1 and □2 on the numerical key TK, the input circuit IC of the shift register SHR inputs the numerical values "1" and "2" from the lower digit to the upper digit of the shift register. In other words, it is a 12-digit register, so after pressing □1 and □2, it becomes 000000000012.

After setting the number like this, press the NO key. In other words, the value just set means the address specification of the memory MR. Therefore, the input value will be any value from 1 to 100. When the NO key is pressed, a one-shot pulse is generated from pulse generator _Q1 .
This pulse operates gate circuit _G5 and transfers the contents of the lower three digits of shift register SHR to three-digit buffer register BR. The contents of this BR retain their original contents until the NO key is pressed. Buffer register BR is essentially memory.
Becomes the MR address register. In other words, this BR
Decode the contents using the address decoder AD to determine the address.

As mentioned above, press the numeric keys □1, □2 to select NO.
Pressing the key accesses the 12th address. In this way, specify the address of memory MR. When the NO key is pressed, the input circuit IC resets the original contents of the shift register SHR with the next numeric key pressed, and inputs the new number starting from the lower digits.

For example, if you want to store the phone number 06-621-1222 in 12 addresses, □0□6□-□6□2□1□-□1□
Press the keys 2□2□2.

Note that the key group EK of H, L, P, and U (symbol input keys) is not input to the shift register SHR except in the W mode, which inputs data to the nonvolatile memory MR, or is input through the gate _G6 only in the W mode. The code is input to the input circuit IC, and the desired code can be input and stored in the shift register SHR. Enter the hyphen "-" in the above phone number using the □- key. The data input to the shift register SHR is displayed with corresponding symbols on the display device DSP.
There is a display inside the DSP and the display is displayed as shown in Figure 2. After inputting data to the shift register SHR, press the NI key, which is the key for inputting to the memory, and a one-shot pulse will be generated from the pulse generator _Q3 , and since the W key is on, gate _G3 will be turned on. and input gate _G1 of memory MR.
Turn it on. Then, input the contents of shift register SHR to the 12th address currently being accessed. In this way, any data can be stored at any address using the NO and NI keys. Naturally, these do not disappear even when the power is turned off.

[When in R mode]

As mentioned above, if the mode switch 6 is set to the R mode, the various data stored in the memory MR can be recalled as needed as described later. If you change it to R mode,
If you want to call up the contents of address 12, press the numeric keys □1□2 and input 12 into the shift register SHR. (Same as W mode.) Then press the NO key. When the NO key is pressed, a one-shot pulse is output from the pulse generator _Q1 , turning on the gate _G5 and transferring the last three digits of the shift register SHR to the buffer register BR. At the output of pulse generator _Q1 , a second one-shot pulse emerges from _Q2 . Gate G ₄ is now ON due to R mode, and output gate G ₂ of memory MR
turns ON, essentially moving the contents of memory MR to shift register SHR. First, in _Q1 , the buffer register BR contains 12 and the memory MR is at the 12th address, so the data 06-621-1222 stored at the 12th address is transferred to the shift register.
SHR is entered, and this is displayed on the display device DSP. In other words, you can display the data you need. Note that gate _G8 is always ON and displays the contents of shift register SHR in CK mode, that is, in other than clock mode.

[When in CK mode]

In CK mode, gate _G7 is ON and _G8 is CFF. CG is an oscillator, DV is a frequency divider, CR is a time counter, and the content of the counter CR is the current time. In other words, when set to CK mode, the current time is displayed on the display device DSP.

[When in CL mode]

When in CL mode, the four arithmetic operation keys FK are given to the computer operation control circuit CLu via gate _G7 ,
A desired operation is performed based on the numerical keys input to the shift register SHR. Then, the calculation result is displayed based on the shift register SHR. At this time, the □-key (SK) is also given to the arithmetic control circuit CLu and serves as a subtraction instruction key.

[When pressing the TU key in CL mode]

Operate shift register SHR as an up counter. In CL mode, the flip-flop FU is set by pressing the TU key, first a one-shot pulse is generated from the pulse generator _Q4 , and the clearing of the shift register SHR is sent to the clearing circuit CLR.
Do it by putting it to work. At the same time flipflop FU
At SET, gate _G9 is turned ON via gate OG, and shift register SHR is circulated via adder/subtractor FA. If the (S) terminal of the adder/subtractor FA is "1", it works as a subtracter, and if it is "0", it works as an adder. One of the inputs of FA is shift register SHR
The other output is the 1-second signal S ₀ from the frequency divider, and each time this 1-second signal S ₀ comes, an addend "1" is given.
In other words, when you press the TU key in CL mode, it first clears the contents of shift register SHR, then 1
Counting up every second. In other words, it works as an amp counter. This shift register
The contents of the SHR will be displayed.

[When pressing the TD key in CL mode]

Flip-flops FU and FD provide reset input by pressing any of the keys. However, since it is an RSS type, for example, when the TU key is pressed, both set and reset inputs are input to the flip-flop FU, but at this time it is set. However, pressing any other key, such as the TD key, will reset the flip-flop FU. When the TD key is pressed, the flip-flop FD is set and the adder/subtractor FA works as a subtracter. Before pressing the TD key, input data into the shift register SHR using the key. Then, when the FD is set, gate _G9 is turned ON and "1" is subtracted from the contents of the shift register SHR every second, so it functions as a down counter. S ₀ is 1
Although a second signal is used, a one minute signal may also be used. Then it will count up or down every minute. Therefore, with the embodiment described above, it is possible to store a series of numbers by specifying an address in the non-volatile memory using the numeric keys, and to read them out using the keys. station number,
It is also possible to input and output numbers by distinguishing them from each other.
Furthermore, if the device is equipped with a clock function that calls the current time, a count function that counts up from 0 seconds, or counts down from a specific number, the functions of this device can be further doubled. Furthermore, calculation instruction keys can be provided so that the four arithmetic calculations can be performed without using numerical keys, and data required for calculations can be shared and displayed on the same display.
In this way, during a telephone conversation, you can use it as a calculator if necessary, and in some cases, you can also calculate telephone charges, which is a great advantage.

In the above embodiments, storage and reading of telephone numbers have been explained in particular, but it goes without saying that the present invention can also be implemented for searching name codes, storing and reading patent numbers, and other types of storage and reading.

As described above, according to the electronic number storage/reading device of the present invention, a series of numbers such as a telephone number and symbols related thereto can be stored together by specifying an address in a non-volatile memory using numerical keys. This has the effect that the number and symbol stored at that address can be output from the memory and displayed.
