In this case, when transmitting to the receiving facsimile machine via the Internet, it is necessary to input the address of the partner facsimile machine as input information. PC).
[Operation of input device]
Next, the operation of the facsimile 1 when it is set to the transmission mode by inputting twice by operating the mode setting key 7d will be described in detail with reference to a flowchart. FIG. 4 is a flowchart relating to the operation in the transmission mode by the two-time input executed by the CPU 15 based on the control program stored in the ROM 21. In START, the mode is set to a mode in which FAX transmission is performed by inputting the FAX number corresponding to the input information of the present invention twice by the operation of the mode setting key 7d by the user. It has become.

  In S101, it is determined whether the first number input has been completed. The number is input by pressing a numeric keypad 7 b provided on the operation panel 7, and the input number is stored in the RAM 25. The pressed numbers are sequentially displayed on the display 7a. Whether or not the input of the first FAX number is completed is determined by whether or not the start key 7e is pressed. If it is determined that the start key 7e has not been pressed (S101: NO), the input is waited until the input of the number is completed and the start key 7e is pressed. When it is determined that the input has been completed (S101: YES), the process proceeds to S102, the pressed number is stored in the RAM 25, the display on the display 7a is stopped, and the second FAX number input waiting state in S103 is entered. become. Whether or not the input has been completed may be determined whether or not a telephone number having a preset number of digits has been pressed.

  Next, in S103, it is determined whether the second FAX number input has been completed. This process is similar to the process performed in S101. When it is determined that the FAX number has not been input (S103: NO), the input waits until the input of the number is completed and the start key 7e is pressed. It becomes a state. If it is determined that the input has been completed (S103: YES), the process proceeds to S104, and the pressed number is stored in the RAM 25. Note that the FAX number input for the second time is also sequentially displayed on the display 7a together with the operation of the numeric keypad.

  Next, the process proceeds to S105 corresponding to the information determination means of the present invention, and the first input FAX number and the second input FAX number stored in the RAM 25 are compared to determine whether they are the same number. Judging. Specifically, the numbers of the same digits of the FAX number input for the first time and the FAX number input for the second time are compared to determine whether the numbers are the same. When it is determined that the FAX number input for the first time is the same as the FAX number input for the second time (S105: YES), the process proceeds to S106, and the FAX transmission operation is started.

  When it is determined that the FAX number input for the first time is different from the FAX number input for the second time (S105: NO), the process proceeds to S107, and among the keys pressed during the second input, the first time It is determined whether there are two or more keys different from the key pressed at the time of input. Specifically, for example, the number of different keys i is counted, and when i> 1, it is determined that two or more places where different keys are pressed exist. In this embodiment, an input error is determined based on the presence of two or more different keys, but it may be set at three or more locations by changing the setting.

  If it is determined that there are two or more places where different keys are pressed (S107: YES), it is determined that an input error has occurred, and the process proceeds to S108 corresponding to the error processing means of the present invention to perform error processing. . Specifically, as shown in FIG. 5, a display for notifying the user that an input error has occurred is performed on the display 7a.

  FIG. 5 is a schematic diagram of the operation panel 7 when an input error occurs. When an input error occurs, it is possible to notify that an input error has occurred by displaying on the display 7a as “INPUT ERROR”. Thereafter, the process again shifts to the first FAX number input waiting state.

  In S107, if it is determined that there are not two or more places where different keys are pressed (S107: NO), the process proceeds to S109 corresponding to the positional relationship determination means of the present invention, and the key pressed for the first time. Among the keys pressed for the second time, the positional relationship of the numeric keys 7b having different numbers is compared to determine whether or not they are adjacent to each other such as up, down, left, and right.

  Here, the S109 determination process will be described in detail by taking as an example a case where the FAX number of the transmission destination is “1234567”. Here, “1234567” is pressed when the first FAX number is input (S101), and “1224567” is pressed when the second FAX number is input (S102). In S107, it is determined that the first third digit of the FAX number is “3” and “2”, and there is one place where a different key is pressed.

  In S109, the position of the numeric keypad 7b corresponding to the upper third digit number “3” of the FAX number pressed first time and the upper third digit number “2” of the FAX number pressed second time are set. It is determined whether the positional relationship of the corresponding numeric keypad 7b is a vertical / horizontal relationship. In FIG. 2, in the numeric keypad 7b provided on the panel 7, the key corresponding to “3” and the key corresponding to “2” are arranged adjacent to each other on the left and right. In this case, although the user recognizes the correct FAX number and presses the numeric keypad 7b, there is a high probability that the user has pressed the adjacent key by mistake (ie, made a mistake), and determines that a mistake has been made. .

  Also, if the first third digit of the fax number pressed first is “3” and the second third digit of the fax number pressed second is “8”, panel 7 In the provided numeric keypad 7b, the key corresponding to “3” and the key corresponding to “8” are not arranged at adjacent positions. In this case, since it is highly probable that the user has recognized the correct FAX number and has not pressed the numeric keypad 7b, it is determined that an input error has occurred.

  If it is determined that the key positional relationship is not the vertical / horizontal relationship (S109: NO), the process proceeds to S108 to perform error processing. If it is determined that the key positional relationship is the vertical / horizontal relationship (S109: YES), the process proceeds to S110 corresponding to the guidance means of the present invention, and the position where the input error has occurred is displayed.

  The process of S110 will be specifically described. FIG. 6 is a schematic diagram of the operation panel 7 when an input error occurs. The display 7a provided on the panel 7 displays the FAX number pressed for the second time and the location where the input error has occurred and allows the user to recognize it and prompt the user to re-enter the number. In FIG. 6, the FAX number “1224567” pressed for the second time, the underline 7 f displayed in the upper third digit number “2”, and the message “Missmatch” are displayed. By displaying an underline at a location where a mistake has been made, the user can recognize the position where the mistake has been made and prompt the user to re-enter the number. In addition, as another means for informing the user of the position where the wrong press has occurred, the wrong number may be blinked, or a message that directly supports re-entry of the number may be displayed.

  If the position of the input error is notified in S110, the process proceeds to S111, and a transition is made to a waiting state for re-input to a location with a different number by the user. The re-input of the number is performed by the user operating the numeric keypad 7b. When the number is re-input by the user, an underline 7f is added on the display 7a, and the number of the displayed part is replaced with the number pressed by the user for re-input. In this embodiment, “2” in the upper third digit is replaced with “3” by operating the numeric keypad 7b. Whether or not the re-input of the number is finished is determined based on whether or not the start key 7e is pressed as in S101 and S103. If it is not determined that the re-input of the number has been completed (S111: NO), the state of waiting for the re-input of the number is continued until the re-input is completed by pressing the start key 7e or the like.

  If it is determined that the re-input of the number has been completed (S111: YES), the process proceeds to S112, and the re-entered FAX number is stored. Specifically, the FAX number (here, “1234567”) completed by re-input in S111 is stored in the RAM 25.

  In step S106, the transmission operation is performed based on the FAX number newly stored in step S112.

  With the above operation, the present invention determines whether or not the FAX number input for the first time matches the FAX number input for the second time, and the positional relationship on the numeric keypad 7b between the numbers that do not match is adjacent. Determine if the relationship is right. If it is determined that the adjacent positional key has been pressed, a message indicating that there is a wrong number and that correction is required is displayed. As a result, even when the user recognizes the correct number and makes a mistake in pressing the key, the correction can be made easily.

In the present embodiment, the ten keys 7b are arranged in a matrix. However, as a modified example of the arrangement of the ten keys 7b, a case in which number keys are arranged in a line is also conceivable. In this case, the present invention can be applied by regarding the keys arranged on the left and right of the respective keys as adjacent positional relation keys.
[Error handling]
Here, a modified example of the error processing in S108 of FIG. 4 will be described in detail. Since the operation of the input device is the same up to S107, it is omitted here and the same reference numerals are used.

  FIG. 7 is a flowchart regarding the recovery process at the time of an input error. In the figure, START is a state in which it is determined in S107 of FIG. 4 that there are two or more different number keys between the first input number and the second input number.

  In S201, the FAX number input for the first time and the FAX number input for the second time are read from the RAM 25 and displayed on the display 7a so as to be selectable. FIG. 8 is a schematic diagram of the panel 7 during error processing. In the figure, the FAX number input for the first time and the FAX number input for the second time are displayed as “1st: 1234567” and “2nd: 12224537”, respectively.

  In step S202, it is determined whether the correct FAX number has been selected by the user. Specifically, the numeric keypad corresponding to the correct FAX number (for example, “1” numeric keypad is pressed if “1234567” is correct, and “2” numeric keypad is pressed if “1224537” is correct). ) To select the correct FAX number. As a method for selecting the FAX number, if the panel 7 has a cursor key, a method of selecting the correct FAX number by pressing the cursor key and determining with the start key 7e is used. May be. If the correct FAX number is not selected (S202: NO), the process waits until it is selected. If it is selected (S202: YES), the process proceeds to S203, and the selected number is input for the first time. It is stored in the RAM 25 as a FAX number.

  Next, in S204, it is determined whether or not the input of the FAX number to be used as the second FAX number has been completed. This process is similar to the process performed in S101. When it is determined that the FAX number has not been input (S204: NO), the input waits until the input of the number is completed and the start key 7e is pressed. It becomes a state. If it is determined that the input has been completed (S204: YES), the process proceeds to S205, and the pressed number is stored in the RAM 25.

  Next, the process proceeds to S105 in FIG. 4, and the process proceeds to a process of determining whether the FAX number corresponding to the first time selected by the user and the FAX number input again (the third time in total) are the same. . In this way, by selectively displaying the FAX number input for the first time and the FAX number input for the second time so that the selected FAX number is the same as the newly input FAX number, When an input error is determined, correction can be easily performed without starting over from the beginning, so that the operability of the apparatus is improved.

  Another modification of error processing will be described. FIG. 9 is a flowchart relating to recovery processing at the time of an input error. START is the same as the START state of FIG. In S301, it is determined whether the FAX number input for the first time and the FAX number input for the second time exist in the telephone directory, outgoing call history, and reception history. The FAX numbers stored as the telephone directory and history are stored in the RAM 25, and it is determined whether the FAX numbers stored in the RAM 25 are the same as those input the first time and the second time.

  If it is determined that there is no corresponding FAX number (S301: NO), it is also determined that there is an input error, and the process returns to S101 in FIG. 4 and shifts to the first FAX number input waiting state. If the corresponding FAX number exists (S301: YES), it is considered that there is a high probability of trying to transmit to the destination in the phone book or history, so the process proceeds to S302, and the corresponding FAX number is displayed.

  Thereafter, the process proceeds to S303, in which the corresponding FAX number is stored in the RAM 25 as the FAX number corresponding to the first time, and the process proceeds to S103 in FIG. 4 to wait for the input of the second FAX number. By using the FAX number stored in the telephone directory or history as described above, the operability of the apparatus is improved because it can be easily corrected when it is determined that an input error has occurred.

  Regarding recovery processing at the time of input error, the following can be considered. FIG. 10 is a flowchart relating to recovery processing at the time of an input error. START is the same as the START state of FIG. In S401, it is determined whether a third FAX number has been input. Here, the display 7a is displayed to prompt the user to input a third FAX number, and the user inputs the FAX number by operating the numeric keypad 7b. If it is determined that the third FAX number input is not completed (S401: NO), the process waits until the input is completed. When it is determined that the number input is completed (S401: YES), the input number is stored in the RAM 25 as the third FAX input number, and the process proceeds to S402.

  In step S <b> 402, it is determined whether the FAX number input for the first time is the same as the FAX number input for the third time. The specific method is the same as S105 in FIG. If it is determined that the FAX number input for the first time and the FAX number input for the third time are the same (S402: YES), the process proceeds to S403, and the FAX number input for the third time is determined as the correct number. In step S404, the FAX transmission operation is started.

  If it is determined in S402 that the fax number input for the first time is different from the fax number input for the third time (S402: NO), the process proceeds to S405, and is input for the second time in the same manner as in S402. The FAX number is compared with the FAX number input for the third time, and it is determined whether the numbers are the same. If it is determined that the FAX number input for the second time is the same as the FAX number input for the third time (S405: YES), the process proceeds to S403, and the FAX number input for the third time is determined as the correct number. In step S404, the FAX transmission operation is started.

  If it is determined that the FAX number input for the second time is different from the FAX number input for the third time (S405: NO), the process proceeds to S406, where it is determined that an input error has occurred, and this is indicated on the display 7a. The process proceeds to S101 in FIG. 4 and shifts to a first FAX number input waiting state. In this way, by shifting to the third FAX number input waiting state and comparing with the previously input FAX number as the correct FAX number, it is determined as a correct FAX number, so that even if an input error occurs, it is not necessary to start over from the beginning. It can be corrected.

  As mentioned above, although this invention was demonstrated based on the Example, this invention is not limited to an Example at all. For example, in this embodiment, the input device is implemented in a facsimile apparatus, but the present invention can also be applied to other apparatuses. For example, a personal computer needs to input a destination address when performing e-mail transmission. At this time, by applying the present invention to the keyboard of the personal computer, correction due to a pressing error is facilitated. Further, for example, when the re-input of the FAX number in S111 is completed, the key positional relationship may be compared as necessary, for example, the key positional relationship may be compared again in S109.
