Is monitored (No loop of the judgment 101). Note that the combination operation of pressing the [function] key 9f and inputting the number “10” using the numeric keypad 9a is an operation for activating the search order setting mode.

When the combination operation is performed (decision 1)
(01, Yes), the search order setting mode is activated, and a message "Press the [Redial] key, numeric keypad, [One-touch] key, or [Shortcut] key in the search order to be set" is displayed on the display unit 91. While displaying and identifying the type of key to be input, it is monitored whether there are four key inputs (process 103, No loop of judgment 104).

Pressing of the [REDIAL] key 9j corresponds to selection of the redial information table 4b, and pressing of the numeric key corresponds to selection of the temporary dial information table of the dial information table 4a. Pressing the [one touch] key 9h corresponds to selecting the one-touch dial information table, and pressing the [abbreviation] key 9g corresponds to selecting the abbreviated dial information table.

If there are four key inputs (Y in decision 104)
es) The key input order is registered in the search order table 4c shown in FIG. 6 and stored in the RAM 4 (process 105).
In FIG. 6, a search target table is associated with each search order. The order “1” is a redial information table, the order “2” is a temporary dial information table, and the order “3”. Corresponds to the one-touch dial information table, and the order “4” corresponds to the abbreviated dial information table. This corresponds to four key inputs in the order of the [Redial] key 9j, the numeric keypad 9a, the [One Touch] key 9h, and the [Shortcut] key 9g in the No loop of the processing 103 and the determination 104.

While the search order is set in this way,
A transmission processing procedure performed in the facsimile machine 1 will be described with reference to FIGS.

In these figures, the system control unit 2 monitors whether a document is set on the scanner 5 (No loop of decision 201), and if a document is set (Yes of decision 201), the system control unit 2 proceeds to FIG. As shown, on the display 9l,
A message "Please specify the destination" is displayed (step 202), and the user is prompted to specify the destination.

Then, the [Shortcut] key 9g is pressed, the [One Touch] key 9h is pressed, the [Redial] key 9j is pressed, or the numeric keypad 9 is pressed.
It is monitored whether a or the alphabet key is pressed (No loop of judgment 203, judgment 204, judgment 205, judgment 206).

Then, the [Shortcut] key 9g is pressed, the [One Touch] key 9h is pressed, or
If the [Redial] key 9j is pressed (decision 20)
Yes of decision 3, Yes of decision 204, or decision 205
Yes), a conventional process corresponding to the depression of each key is performed (process 207). Specifically, the destination symbol string corresponding to the pressed key is specified by referring to the dial information table 4a and / or the [redial] information table 4b, and transmission is started by pressing the [Start] key 9b. Is instructed, G
3. Perform facsimile transmission by G4 facsimile protocol or e-mail protocol.

When the numeric keypad 9a or the alphabet key is pressed (Yes in the judgment 206), that is, when the transmission destination is designated by manual dialing, the processing after the processing 208 is performed. The pressing of the alphabet key means that the [one touch] key 9h is pressed while the [ALT] key 9i is pressed.

In the process 208, a symbol corresponding to the key pressed in the judgment 206 is displayed on the display unit 91 (process 208). Specifically, when the key pressed in the determination 206 is the alphabet “A”, as shown in FIG.
"A" is displayed.

Then, a cursor is displayed at the last input symbol position (step 209). Specifically, when the last symbol input in the determination 213 described later is the second “b” of the destination symbol string, the position of the symbol “b” is determined as shown in FIG. Next, a cursor display with an underbar “_” shape is performed (step 209). As a result, the symbol string of the input part of the transmission destination symbol string is changed to the part of the destination symbol string obtained as a result of the search described later, excluding the symbol string of the input part (highlighted as described later). ) Can be clearly distinguished and displayed. Note that the cursor display in the process 209 may be a blinking display, and may be an inverted / non-inverted blinking display instead of the underbar shape.

Referring to the search order table 4c of FIG. 6, the search target tables of the redial information table 4b, table dial information table, one-touch dial information table, and abbreviated dial information table are registered in the registered search order. A search is made to see if there is a matching destination symbol string (process 210). In other words, a search is made for a destination symbol string whose head part matches the previously input partial symbol string.

If there is a matching destination symbol string (Yes at decision 211), the matching destination symbol string is displayed on the display unit 91, and the parts other than the input part are highlighted and displayed. The form is different, and the distinction from the input part is clarified (process 212). In addition to the reverse display, a different color display or the like may be used.

More specifically, in FIG. 9, first, when the inputted partial symbol string "a" is compared with each information table in the search order registered in the search order table 4c of FIG. 6, the redial information table 4b The corresponding destination symbol string “aaa@bbb.ricoh.co.jp” of the record with the registration number 01 of the temporary dial information table of the dial information table 4a corresponding to the registration number 3 of the destination information table 3a is a matching destination symbol string. If the displayed destination symbol string “aaa@bbb.ricoh.co.jp” is a transmission destination desired by the user, a determination 214 described later is made.
In step 2, the [Start] key 9b is pressed and the destination is determined. If not, the numeric key 9a or the alphabet key is further pressed in the determination 213 described later, and the processing from step 208 is repeated.

Then, in the judgment 213, the alphabet "b" is inputted, and the inputted partial symbol string is "ab".
, The partial symbol string “ab” is collated with each information table in the search order registered in the search order table 4c of FIG. 6, and the registration number 1 of the redial information table 4b is registered.
The destination symbol string “abc@def.ricoh.co.jp” of the record of the registration number 02 of the one-touch dial information table of the dial information table 4a corresponding to 0
Becomes the destination symbol string that matches.

If there is no match in the redial information table 4b of the search order "1", the tables of the search order "2", "3", and "4" are searched in order. . By setting the search order in this way, a search suitable for each user's usage pattern can be performed.

After the process 212, or when there is no matching destination symbol string in the judgment 211 (N in the judgment 211)
o) Then, it is monitored whether the numeric keypad 9a or the alphabet key is pressed, or whether the [Start] key 9b is pressed (No in decision 213, N in decision 214).
o loop). When the [Start] key 9b is pressed (Yes in decision 214), the transmission destination symbol string displayed on the display unit 91 as shown in FIG. 9 is regarded as the input transmission destination symbol string. Then, the transmission destination is determined (step 215). The determination of the transmission destination symbol string determined as the transmission destination in step 215 is Yes
Thus, there is a case where the destination symbol string is predicted and displayed based on the inputted partial symbol string, and a case where it is the inputted partial symbol string itself.

In the former case, the symbol string of the destination is predicted and displayed, so that the number of key inputs required to determine the transmission destination is 20 times (19/19 for the number of symbols of the mail address) when the prediction is not displayed. Twice (the sum of one press of the [Start] key 9b) and two times of the partial symbol string "ab" of the mail address and the [Start] key 9
The transmission destination can be determined by the key operation of (a total of one press of b). In the latter case, it is substantially the same as a conventional manual dial.

When the transmission destination is determined in process 215, facsimile transmission processing (in this case, facsimile transmission by electronic mail) is performed on the determined transmission destination. When the input destination symbol string is the telephone number of the destination, processing is performed in the same manner as in the case of the mail address.

If the numeric keypad 9a or the alphabet key is pressed in the judgment 213 (Yes in the judgment 213)
s) Returning to the process 208, the processes 208 to 21
Repeat step 2.

In the above-described procedure for inputting and confirming the transmission destination symbol string, the description of the procedure in the case of an erroneous input is omitted. However, in the case of an erroneous input, the [Stop] key 9c is depressed. All the partial symbol strings that have been input so far (and the symbol strings that have been searched and predicted and displayed) are all cleared. By pressing the [Clear] key 9k, the last symbol of the partial symbol string that has been input can be cleared.
When the last symbol is cleared by pressing the [Clear] key 9k, the information table to be searched is searched in the registered search order for the destination symbol string that matches the remaining input partial symbol string. , And redisplayed on the display unit 91 to return the display state to the state before the cleared symbol is input. As a result, even when an erroneous input is made, the predicted display of the destination symbol string can be correctly performed.

As described above, according to the present embodiment, a partner who has communicated in the past or a partner registered in one-touch dialing or abbreviated dialing as a partner having high communication frequency can be manually registered. When the destination is specified by dialing, if you do not enter the entire symbol string of the destination, enter the symbol string at the beginning,
If the destination symbol string starting from the input symbol string is predicted and displayed, and the user approves the predicted and displayed destination symbol string and confirms it with the [Start] key 9b,
The destination can be specified with a few key operations, and the input operation of the symbol string of the destination can be simplified in a facsimile apparatus having a limited symbol input function.

In the above-described embodiment, the present invention is applied to the case where the symbol string of the transmission destination is determined by predicting and displaying the input partial symbol string based on the information registered in the past. However, the present invention is not limited to this, and can be similarly applied to a case where a symbol string of various information is predicted and displayed from an input partial symbol string based on information registered in the past and determined. Things.

In the embodiment described above, the present invention is applied to a facsimile apparatus which is one of the communication terminal apparatuses. However, the present invention is not limited to this, and is applicable to other communication terminal apparatuses. It is applicable to.
