The present invention provides a video cassette (VCR) having a digitron for displaying letters and numbers, wherein the information of a telephone number using letters and numbers can be reliably stored and retrieved when necessary. An electronic handbook using a digitron (hereinafter referred to as a VCR) and an information input / output method thereof.

Generally, Digitron is a kind of display tube, which consists of cathode (acceleration) and anode (for display), and divides the light emitting anode into different shapes on the pattern to display numbers, letters, etc. It is well known that the marking required by the combination of the input signal voltages applied to the divided anodes after painting is made.

In the related art, only a simple display function of displaying the mode, clock, channel number, etc. of the VCR in English letters and numbers is performed through the digitron of the VCR.

Therefore, if you have the function of the electronic processor to store and retrieve the phone number using the microprocessor's processing power and memory and keyswitch, the product's level and added value will be increased.

Accordingly, an object of the present invention is to provide an electronic handbook and a method for inputting and outputting information using a digitron of a VCR for inputting information of a telephone number as alphabetic characters and numbers and searching or clearing it if necessary.

To this end, the present invention is a conventional device, such as a channel up / down key switch, 0 to 9 number key switch, Cree key switch, etc. in a device such as a VCR having a digitron, which is a display device that shows English letters and numbers. A key input unit for adding a set key switch and a review key switch to recognize various options of the user; A microprocessor which receives a user's option from the key input unit and controls the overall operation; A memory for storing or outputting data under the input / output control of the microprocessor; A program memory for inputting information such as order, condition, etc. necessary for the operation control of the microprocessor to perform an accurate operation; A driver configured to set a driving voltage and a supply path thereof under the control of the microprocessor; Digitrons that display letters or numbers required by the drive voltage input from the drive unit through an arbitrary supply path can be used to store alphabetic names and telephone numbers in memory according to the user's selection through the key input unit. It has an additional function of an electronic organizer for searching or creeping it.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Set to existing key switches such as channel up / down key switch (CH U / D), number key switch 0 to 9 (0) to (9), clear key switch (CLEAR), shift key switch (SHIFT) Depending on the state of installing the key input unit (1) (1a) and the key input unit (1) (1a) to recognize the various options of the user by adding the key switch (SET), review key switches (REVIEW) A microprocessor (4) for receiving the optional specification in the form of a wireless signal through the remote controller (2) or a wired signal through the control panel (3) of the device and detecting the type thereof to control the overall operation; A memory (5) for storing data at a necessary address or outputting the stored data under the input / output control of the microprocessor (4); A program memory (6) for inputting information such as order, condition, etc. necessary for operation control in the microprocessor (4) so as to perform an accurate operation; A driving unit 7 outputting a driving voltage arbitrarily set under the control of the microprocessor; It is composed of digitrons 8 which display the necessary letters or numbers while the corresponding part is turned on by the driving voltage outputted from the driving unit 7 in an arbitrary supply path.

The electronic organizer using the digitron of the VCR of the present invention configured as described above can be used for electronic products such as a VCR having a display function such as a digitron for displaying alphabets and Arabic numerals and an OSD (ON screen display), 1), a process of inputting information using the microprocessor 4 or the like will be described.

First, when the user turns on the power key switch (not shown in the figure) of the key switches of the key input unit (1) (1a) installed in the remote control unit (2) or the control panel (3) so that the device can be operated (step 10). In the microprocessor 4, it is checked whether the secret key switch SET is turned on (step 11). If it is turned on, the microprocessor 4 enters the information input mode of the notebook, that is, the set mode (step 12).

Next, use the channel up / down key switches (CH U / D) to select the desired alphabetic characters (A) to (Z) and (-) for the four letter digits of the digitron (8). Enter (step 13). At this time, if the letters (A) to (Z) and (-) are displayed sequentially while the channel up / down key switch (CH U / D) is being pressed, the channel up / down (CH U / D) is lost. When releasing, ie off, the digits of the digitron 8 display the alphabetic character of the moment of release of the hand.

In this way, if the name is entered in the digits as the letters (A) to (Z) and (-) within the specified number of seconds (step 14), the first digit of the seven-digit digit for the telephone number will flash and the number will be requested. (Step 15).

If the telephone number to be input is 7 digits (step 16), the 7 digits are entered in sequence using the numeric key switches 0 to 9 from the first digit to 0 to 9 (step 17).

If the telephone number to be entered is 6 digits, turn the shift key switch (SHIFT) on once to move to the next digit (step 18), and then use the numeric key switches 0 to 9 from 0 to 9. To input six digits in sequence (step 19).

Check whether all 7- or 6-digit telephone numbers have been entered (step 20), and if so, all names and telephone numbers entered so far are flashed and stored in memory (step 21).

Then, when the user turns on the set key switch SET of the key input section 1 (1a) again (step 22), the above information is stored in the memory 5 (step 23), and then another selection key switch is turned on. If it is turned on (step 24), if it is turned on, the mode is changed to perform the corresponding mode (step 25), or the next setting mode is entered to input the following information (step 26).

When the information stored in the memory 5 is creeped, the microprocessor 4 recognizes when the user turns on the review key switch REVIEW as shown in FIG. 3 (step 30). The name of the information stored in the memory 5 is displayed in alphabetical order with the fastest data (Initial Data) displayed on the digitron 8 while driving the drive unit 7 (step 31), and the user switches the channel up / down keys. After confirming that (CH U / D) is turned on within a few seconds (step 32), the next data is displayed when turned on (step 33).

Check whether the channel up / down key switch (CH U / D) is turned on again (step 34), and if it is turned on, the next data is output (step 35), Check whether the CLEAR switch is turned on at the same time (step 36), and only when the CLEAR switch is turned on within a few seconds, the currently displayed data is erased at the corresponding address of the memory 5, and ends. Step 37).

On the other hand, when the user wants to search the input information, as shown in FIG. 4, it is checked whether the review key switch (REVIEW) of the user key input unit 1 (1a) is turned on (step 40). After displaying the data of the information stored in the memory 5 in the alphabetical order of the name (step 41), whether the channel up / down key switch (CH U / D) is on again within a few seconds. Confirmation (step 42) displays the following data only if it is on (step 43).

Then, it is checked whether the channel up / down key switch (CH U / D) is on within a few seconds (step 44), and continuously display the next data only when it is on (step 45), and on within a few seconds. If not, exit.

Therefore, the electronic organizer using the digitron of the VCR of the present invention stores or stores information of a name and telephone number desired by the user in the memory 5 while using the digitron 8, which is a VCR's alphanumeric display means. It can be seen that the information and value added of the VCR are increased by searching or clearing the information.
