Abstract

PURPOSE:To surely call an opposite party by excluding a registered character string having no alphanumeric to be allocated to the key to be depressed in the n-th order in the n-th digit, and when only one registered character string is left, deciding the character string as an input character string. CONSTITUTION:When the n-th (= 1st) key is depressed, whether 'name' (registered character string) stored in a storage part 11a-2 includes a character coincident with any alphanumeric allocated to the depressed key in the n-th digit or not is discriminated. When at least one 'name' includes the alphanumeric allocated to the depressed key in the n-th digit (= 1st digit), 'names' having no alphanumeric allocated to the depressed key are excluded from the objects to be used for the decision of coincidence. When only one 'name' is left, the name and the telephone number corresponding to the name are displayed on a display part, and when a SEND key is depressed, the telephone number is transmitted to a transceiver unit 12 to call the terminating subscriber. Consequently, telephone calling can be attained and the locked state can be released.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an input character string discrimination method, and is particularly applicable to a car telephone device etc. equipped with a key part for inputting a plurality of alphanumeric characters with one key. The present invention relates to a suitable input character string discrimination method.

<Prior art> The demand for car telephone devices is increasing due to the expansion of motorization, business, security, etc., and they are equipped with various functions related to ease of use, such as a call function using abbreviated numbers, and lock functions. .

To make a call using an abbreviated number, register the telephone number in advance in memory according to the two-digit abbreviated number from OO to 99, and when the abbreviated number is input, read the telephone number corresponding to the abbreviated number from the memory. It is for making a call. Further, the lock function makes it impossible to make a call to the other party by pressing the lock key to keep the phone in a locked state, thereby preventing anyone other than the owner from making a call without permission. Note that to release the locked state, a predetermined II) code that has been registered in advance must be input.

<Problem to be solved by the invention> By the way, when making a call using an abbreviated number, the abbreviated number 3.
There are cases where the user forgets the response of the other party, and in such a case, there is a problem in that it is not possible to make a call using the abbreviated number.

Furthermore, there are cases where the user forgets the registered ID number when unlocking, and in such a case, there is a problem that the locked state cannot be released quickly.

From above, an object of the present invention is to register a telephone number y in correspondence with a character string consisting of a plurality of characters (for example, an alphabet I character string representing a name), or to register an ID code in a similar manner to a name. , etc., and by inputting these registered character strings, you can call the other party or release the locked state of the car. The purpose is to provide a method.

By the way, in automatic 11F telephone devices with a limited number of keys, multiple alphanumeric characters (including symbols) are assigned to one key, and each time the key is pressed, the alphanumeric characters are displayed in a predetermined order. , one selected alphanumeric character can be entered. With such a character input method, inputting a registered character string becomes extremely troublesome. Therefore, another object of the present invention is 9. To provide a manual character string discrimination method that enables input of functional character strings by simple key operations.

Means for Solving the Problem> In the present invention, the above problem is solved by assigning a plurality of alphanumeric characters to one
2, a key that displays alphanumeric characters in a predetermined order each time it is operated, and a key that manually inputs the selected alphanumeric character, and a registered character string that displays the alphanumeric character assigned to the nth key operated. There is a means for determining whether the registered character string exists in the n-th digit, a means for excluding registered character strings that do not exist, and finally, when ↓ registered character strings remain, the registered character string is used as the input character string. This is achieved by determining means 3-.

<Operation> When one registered character string remains after excluding any registered character string that does not correspond to the alphanumeric character assigned to the nth digit of the key operated, the registered character string is Determine it as an input string. Also, for all digits of the registered character string, it is determined whether the nth character is included in the alphanumeric character assigned to the nth operated key, and if it is included, the registered character string is is determined to have been input.

Hereinafter, call control using abbreviated number/name and unlocking control based on ID input will be explained in detail according to the flowcharts shown in FIGS. 5 and 6.

(a Short number/Previous call control) Before explaining the call control, we will explain the registration of telephone numbers and names in correspondence with abbreviated numbers.

To register only the registered telephone number of the supervisory number side in correspondence with the abbreviated number, click (
a) After operating NO, (K61), input the predetermined abbreviated number to specify the address of the storage section 11a-2, and (
b) Next, enter the phone number, and (c) Finally, operate the 5TOR key (K32) and enter the abbreviated number again.
d) The entered telephone number is registered at the specified address.

To register a name in correspondence with an abbreviated number along with a telephone number and a registered phone number, (a) After operating No. (K61), input the prescribed abbreviated number and store it in the storage section 11a-2. After specifying the address, (b) then entering the phone number, and (c) signing,
After operating the NAME key (K62), enter a predetermined name, for example in alphabetical characters, and (d) finally press the 5TOR key (
By operating K32) and inputting the abbreviated number again, the input telephone number and name will be registered at the designated address.

Incidentally, inputting the alphabet is performed as follows. For example, if it is desired to input the alphabet rCJ, the key 41 is pressed. As a result, the alphabet "A" is displayed blinking at a predetermined position on the display section, and then when the key 41 is pressed again, the alphabets 1 to r A J
Instead, "B" is displayed in a blinking manner, and when the key 41 is further pressed, Alphabella hrcJ is displayed in a blinking manner.At this point, the key 33 (Enter/Shift 1 to key) is pressed. When 33 is pressed on the key, only Alphabella L-C blinks? lff and C is input (
C is displayed as is), and the next character can be entered. Then, when the next key is pressed, a predetermined character is displayed in a blinking manner at an adjacent position, and subsequent characters are input in the same manner.

With the above operations, when a telephone number or a character string consisting of multiple alphanumeric characters (for example, first name 11 sun) has been registered in association with the abbreviated number, a telephone call using the abbreviated number or name will be made as follows. .

That is, the processor 1la-1 in the control unit '1.1a is placed N
Check whether the O key (K61) is pressed (step 101); if not, press the NAME key (K61).
2) is pressed (step 102).

If the No key is pressed, wait for the abbreviated number to be input, and if the abbreviated number is input (step),
03), the telephone number is read from the memory address indicated by the abbreviated number and displayed on the display section (step 104). In this state, if the 5END key is pressed (step 105), the telephone number is transmitted to the transceiver unit y h 124m and a call is made (step 1
06).

On the other hand, if the NAME key is pressed, the processor
At the same time as n (step 07), it is checked whether key personnel are available (step 108).

When there is a key operation, that is, when the nth (=1)th key operation is performed, the name J (f-character string) stored in the storage unit 11a-2 is assigned to the operated key. It is determined whether the n-th digit has a character that matches any alphanumeric character (step 109).If none of the "names" have the alphanumeric character assigned to the operated key, it The process is assumed to have been performed manually and the process waits for the next key operation.

On the other hand, if at least one "name" has an alphanumeric character assigned to the operated key in the n-th digit = 11 (=] digit), the "name" that does not have the alphanumeric character assigned to the operated key will be subject to subsequent match determination. (step 110). Next, check whether a "name" having alphanumeric characters assigned to the operated key has been created, or in other words, whether the name to be manually assigned to the key has been identified in step 11.1. ), if there are 2 or more and cannot be identified, set n + 1 → n and advance n by one step step 112), wait for the next key human power and step]
Repeat the process from 09 onwards.

In step 111, if only one "name" remains, it is assumed that the operator is about to enter the "name", and the name and the telephone number corresponding to the name are displayed on the display (step 111). 113). If the 5END key is pressed in this state (step 114-
), transmits the telephone number to transceiver unit I-1-2 to make a call (step E06).

℃σTD Manual lock control Before explaining the lock release control, let us explain the ID code registration 12-1. This section explains the record (amendment).

To register an ID code, press the F key (K31) and the 8 key (K2S) at the same time, then enter the ID code as a character string consisting of multiple alphanumeric characters (for example, a name consisting of 6 alphanumeric characters 1-). ) and finally input the F key again, the input ID code becomes the new ID code and is stored in the storage unit 1.1. It is stored in a-3.

With the above operations, in a state where the ID code is registered as a name, etc., pressing the F key and the 3 key (K4.2) will enter the locked state. The lock state is released as follows.

The processor 1la-1 of the control unit 1.1a changes from 1 to n and waits for the key force for unlocking (steps 201 and 202), and when there is the key force, that is, there is the nth key operation. Then, it is determined whether the character in the nth digit of the registration ID matches any alphanumeric character assigned to the operated key (step 203). If it does not match any of the alphanumeric characters, it is assumed that an incorrect ID code has been input, and the process is terminated, waiting for the next key operation.

On the other hand, if the nth digit of the registered ID is included in the alphanumeric characters assigned to the operated key, it is considered a match, and then a check is made to see if all the digits of the registered ID match (step 204). , if all the digits do not match, n+1->n is set and n is advanced by one step (step 205), and the process from step 203 is repeated after waiting for the next key input.

Then, if all the digits match in step 204, the locked state is released (step 206).

Although the present invention has been described above for a case where it is applied to a car telephone device, it goes without saying that the present invention can be applied not only to a car phone device but also to other devices.

<Effects of the Invention> According to the present invention, registered character strings are matched with names, etc., and
By storing a telephone number, ID code, etc. in correspondence with the name, it is possible to make a telephone call by inputting the name, and also to release the locked state, thereby improving operational performance.

Further, according to the present invention, a registered character string (name) that does not have an alphanumeric character assigned to the nth operated key in the nth digit.
is excluded, and when one registered character string remains, or when all digits match the registered character string, the registered character string is determined to be the input character string. Therefore, inputting a name that is a registered character string can now be done easily.
