[0055] Bus 24 is a line that connects CPU 11 and other sections such as ROM 12 and RAM 13.

[0056] FIG.3 is a functional block diagram showing facsimile apparatus 1 according to the embodiment above.

[0057] Coordinate position detection section 31 detects coordinates on the screen of display 3A (hereinafter referred to as “pointing coordinates”) of the position on touch panel 3B that a pen or finger touches (hereinafter referred to as “focus”).

[0058] Facsimile apparatus 1 according to the present embodiment comprises browser function section 32. This browser function section 32 has functions compliant with the HTTP (Hyper Text Transfer Protocol) standard.

[0059] More specifically, HTML analysis section 33 analyzes HTML documents read from, for example, a WWW server on the network or internal HTML documents read from FROM 14.

[0060] HTML display section 34 outputs display data according to the analysis result from HTML analysis section 33.

[0061] Browser input device 35 receives inputs to the browser function such as URL inputs, link destination inputs, inputs to HTML document input fields and performs processing according to these inputs.

[0062] HTML document requesting section 36 requests a WWW server to transfer an HTML document in response to an input to browser input device 35 according to HTTP. HTML document requesting section 36 also reads internal HTML documents stored in FROM 14.

[0063] The display data output from HTML display section 34 above are displayed by display control section 37 on LCD display 3A.

[0064] Determination section 38 receives pointing coordinates from coordinate position detection section 31, and it also receives coordinates of an input field (hereinafter referred to as “input field coordinates”) in a HTML document from HTML display section 34. Through this, determination section 38 determines whether or not pointing coordinates are within the input field coordinates.

[0065] Soft keyboard 39 is an input device for entering symbols and numbers, hiragana, katakana, kanji, displayed on LCD display 3A.

[0066] Dial screen 40 is a screen containing the dial that is displayed on LCD display 3A according to an internal HTML document and used to enter telephone numbers. Touching the dial section allows operations equivalent to dial keys 4.

[0067] Input device control section 41 sends inputs from dial keys 4, soft keyboard 39 and dial screen 40 to browser input device 35 and communication control section 18 based on the determination by determination section 38.

[0068] Setting table 42 stores various setting contents of facsimile apparatus 1 according to the present embodiment. As shown in FIG.4, flag F1 is set to ON when the focus is in an input field of the HTML document. Flag F2 is set to ON when soft keyboard 39 is requested to be displayed. Flag F3 is set to ON when dial keys 4 are also used for browser inputs. Moreover, flags F4 to F8 are set to ON according to the type of the soft keyboard input mode. Determination section 38 determines the transmission destination of the input of the input device taking account of flags in setting table 42.

[0069] Hookoff detection section 43 detects a hook off of handset 6 via communication control section 18 and informs it to determination section 38.

[0070] Then the operation of facsimile apparatus 1 as shown above is explained. FIG. 5 is a flow diagram showing steps of control when a touch is produced on touch panel 3B of facsimile apparatus 1 according to the embodiment of the present invention.

[0071] In step (hereinafter referred to as “ST”) 501 determination section 38 checks whether or not there is an input to touch panel 3B, that is, determination section 38 checks whether or not there is a contact by a pen or finger.

[0072] If there is an input, in ST502 determination section 38 checks whether or not the focus is in an input field of the HTML document. More specifically, determination section 38 checks whether or not the focus is in the input field on the screen specified by an INPUT tag of the HTML document.

[0073] If the focus is found in the input field in ST502, the “focus HTML input field” flag F1 of setting table 42 shown in FIG. 4 is set to ON in ST503.

[0074] Then, in ST504, determination section 38 checks whether the “soft keyboard display” flag F2 in setting table 42 is ON or OFF. If it is ON, soft keyboard 39 is displayed on the screen in ST505.

[0075] FIG. 6A is a drawing showing an example of screen containing the input device of facsimile apparatus 1 according to the embodiment of the present invention. FIG. 6B is a drawing showing an example of screen on which the soft keyboard is displayed. On screen 61, a plurality of input fields 62 to 64 specified by INPUT tags in the HTML document are displayed. If the focus is in one of input fields 62 to 64, soft keyboard 65 is displayed as shown in FIG. 6B.

[0076] Here, inputs by soft keyboard 65 are explained using FIG. 6A and FIG. 6B. The screen shown in FIG. 6A is as screen for ordering oranges, apples and grapes.

[0077] An ordering operation is completed by the operator entering the numbers of ordering items and then touching transmission button 66. Input fields 62 to 64 next to the numbers of ordering items are described with INPUT tags. Touching these input fields 62 to 64 displays soft keyboard 65 as shown in FIG. 6B. For example, if the operator wants to enter “12”, the operator needs to touch “1”, “2” and “End” on soft keyboard 65, in that order.

[0078] On the other hand, if the focus is not in the input field in ST502, the “focus HTML input field” flag F1 in setting table 42 is set to OFF in ST506. Then, in ST507, determination section 38 determines whether or not the focus is in the dial icon section of dial screen 40.

[0079] If the focus is on a dial icon in ST507, dial input processing is performed in ST508. More specifically, each of the dial icon of dial screen 40 corresponds to a number or a symbol (*, #). Therefore, the operator can enter data of the corresponding numbers or symbols in input device control section 41 by touching any dial icon with a finger or a pen. The input data are sent by input device control section 41 to communication control section 18 as telephone dial data.

[0080] Then, a case where dial keys 4 are pressed in facsimile apparatus 1 according to the present embodiment is explained. FIG. 7 is a flow diagram showing steps of control when dial keys 4 are pressed in facsimile apparatus 1 according to the embodiment of the present invention.

[0081] In ST701, determination section 38 checks whether or not dial keys 4 have been pressed. If dial keys 4 are pressed, in ST702, determination section 38 checks whether or not the “dial key/browser input dual-function” flag F3 is ON in setting table 42.

[0082] If it is ON, it checks whether or not “Focus HTML input field” flag F1 is ON in ST703. If it is ON, determination section 38 determines that the input data of dial keys 4 be subjected to browser input processing. More specifically, if one of dial keys 4 is pressed, the number or symbol assigned to the relevant key is entered. These input data are sent by input device control section 41 to browser input device 35 of browser function section 32.

[0083] On the other hand, in ST702, if the dial key/browser input dual-function flag F3 is OFF, in ST705, determination section 38 determines that the dial keys be used for dial input processing. More specifically, if one of dial keys 4 is pressed, the number or symbol assigned to the relevant key is input to input device control section 41. The input data are sent to communication control section 18 by input device control section 41 as telephone dial data.

[0084] In ST703, if the focus HTML input field flag F1 is OFF, in ST705, determination section 38 determines likewise that the dial keys be used for dial input processing.

[0085] As described above, according to the present embodiment, if the focus is in an input field of the HTML document, the input data from dial keys 4 are sent to browser input device 35 of browser function section 32. This allows the dial keys 4 to be used also for browser input. That is, hard keys used exclusively for entering call numbers can also be used for inputs to hypertexts i.e. hypertexts, such as html documents. Therefore, the operability in entering data in the browser can improve for operators who would feel it easier to enter data from dial keys 4 than soft keyboard 39. This is because this embodiment can provide those who are unfamiliar with operations of the soft keyboard with operations with the hard keys which are conventionally more familiar.

[0086] The use of dial keys 4 without soft keyboard 39 being displayed prevents the screen of LCD display 3B from being occupied by soft keyboard 39, without reducing the display area. This prevents input fields of HTML documents from being hidden.

[0087] The simultaneous use of dial keys 4 also for browser inputs and display of soft keyboard 39 are determined according to the content of setting table 42. Thus, dial keys 4 or soft keyboard 39 can be selected and used according to the operator's preferences. The switching between the two is also automatically performed and the operator need not be aware of it.

[0088] Then, in facsimile apparatus 1 according to the present embodiment, control of the input device according to the input mode of the dial keys is explained. FIG. 8 is a flow diagram showing steps of control of the input device in facsimile apparatus 1 of the present embodiment according to the dial key input mode.

[0089] Facsimile apparatus 1 according to the present embodiment can enter hiragana, katakana and alphabetic characters using dial keys 4. It also has a function to convert hiragana and katakana characters entered to kanji characters. For example, kanji conversion is performed by pressing down the “*” and “#” keys after entering hiragana characters, etc. The input modes of dial keys 4 are switched by assigning a mode change function to the “*” or “#” key, for example, and pressing them .

[0090] In ST801, determination section 38 checks based on the dial key/input mode flags in setting table 42 whether or not the input mode of dial keys 4 is numeric.

[0091] If the input mode is numeric, in ST802, determination section 38 determines that the input data of dial keys 4 be subjected to browser input processing. More specifically, when one of dial keys 4 is pressed, the number or symbol assigned to the relevant key is input to input device control section 41. These input data are sent to browser input device 35 of browser function section 32 by input device control section 41.

[0092] On the other hand, in ST801, if the input mode of dial keys 4 is not numeric, when one of dial keys 4 is pressed in ST803, the number assigned to the relevant key is stored in RAM 13 as the 1st digit of a character code. In the same way, the numbers input from dial keys 4 are stored one by one. In ST804, it is checked whether or not numbers have been entered up to the number of digits of the character codes. If numbers have been entered up to the number of digits of the prescribed character codes, in ST805, the numbers stored in RAM 13 are handed over to browser input device 35 as character codes. The character codes are converted to the corresponding characters by a conversion function incorporated in input device control section 41.

[0093] As shown above, according to the present embodiment, dial keys 4 can enter not only numbers but also alphabetic characters, hiragana, katakana, and kanji.

[0094] Then, details of dial input processing are explained. FIG. 9 is a flow diagram showing steps of dial input processing in facsimile apparatus 1 according to the present embodiment.

[0095] In ST901, determination section 38 determines whether or not PSTN 16 is being used. If it is not used, in ST902, input device control section 41 checks whether or not there are telephone dial data from dial keys 4.

[0096] In ST902, if data from dial keys 4 are not telephone dial data, in ST903, determination section 38 checks whether or not there are dial icons of dial screen 40, that is, telephone dial data from touch panel 3B.

[0097] In ST902 and ST903, if there is any entry of telephone dial data, in ST904, determination section 38 instructs communication control section 18 to send the telephone dial data to PSTN 16. Here, the telephone dial data can be sent to PSTN 16 one by one or all telephone dial data can be stored temporarily in RAM 13 and then sent altogether to PSTN 16 when handset 6 is off-hooked.

[0098] On the other hand, in ST901, if PSTN 16 is in use and, in ST904, no telephone dial data from both touch panel 3B and dial keys 4 are sent, inputs from touch panel 3B and dial keys 4 are ignored and the telephone dial data disabled in ST905.

[0099] As shown above, the present embodiment allows dial inputs from both touch panel 3B and dial keys 4. Thus, if it is difficult for the operator to see dial keys 4 or operate them due to a certain angle of elevation of touch panel display 3, the operator can perform dial inputs from dial screen 40. Furthermore, telephone dial data are sent to PSTN 16 only when PSTN 16 is not in use, which will prevent call processing from being mistakenly executed during a call.

[0100] Then, dial input processing is explained in detail. FIG. 10 is a flow diagram showing steps of dial input processing in facsimile apparatus 1 according to the present embodiment.

[0101] As shown above, if the operator browses a HTML document and moves the focus to an input field of the HTML document, the input mode of dial keys 4 is switched from dial input to browser input. Control of the input device when handset 6 is detached in this state is performed as follows.

[0102] First, in ST1001, determination section 38 checks whether or not handset 6 is detached. This checking is performed by hook-off detection section 43 detecting that NCU 15 has been connected to PSTN 16 due to detachment of handset 6.

[0103] When handset 6 is detached, in ST1002, determination section 38 instructs input device control section 41 to switch the transmission destination of the input data from browser input device 35 to communication control section 18.

[0104] In ST1003, determination section 38 checks whether or not dial input is completed. When dial input is completed, determination section 38 starts the timer in ST1004. After confirming that a given time has elapsed in ST1005, determination section 38, in ST1006, instructs input device control section 41 to return the transmission destination of the input data from dial keys 4 from communication control section 18 to browser input device 35.

[0105] As shown above, according to the present invention, the output destination of the dial keys 4 can automatically return from the communication control section 18 to the browser input device 34. Therefore, the operator can perform dial inputs and browser inputs using dial keys 4 without being aware of it at all.

[0106] Furthermore, when a given time has elapsed after the entry of a call number from dial keys 4 was completed, the output destination of dial keys 4 is returned from communication control section 18 to HTML input field 35. Thus, after a communication is established, entries can be made to the HTML documents again. The operator need not be aware of the restoring process, either.

[0107] The present invention allows dial keys 4 to be used also for browser inputs and for entering characters and symbols other than numbers. Therefore, it is preferable to indicate whether dial keys 4 are to be used also for browser inputs or exclusively for dial inputs, and display the input mode of dial keys 4 on the screen to allow the operator to grasp it at first sight.

[0108] More specifically, according to the results of checking performed by determination section 38 in ST702 of the flow diagram in FIG. 7, icons, etc. are displayed on the screen of LCD display 3A or separately provided LED lamps are lit to indicate whether or not dial keys 4 are used also for browser inputs. For example, as shown in FIG. 1, at the top right of touch panel display 3 is browser input LED 203 for indicating whether or not dial keys 4 are used also for browser inputs, next to power supply LED 201 and answering LED 202 for showing ON/OFF of the automatic message recording function.

[0109] Furthermore, in ST801 shown in FIG. 8, determination section 38 determines the input mode of dial keys 4, checking whether it is numeric or character code and based on this result it displays the input mode on LCD display 3A using icons or characters, etc

[0110] Facsimile apparatus 1 according to the present embodiment can freely change the angle of elevation of touch panel display 3 as shown above. Depending on the angle of elevation, dial keys 4 may be hidden behind touch panel display 3, for example, when touch panel display 3 is laid with its screen facing upward.

[0111] FIG. 11A to FIG. 11C are drawings showing transition of angle adjustment of the touch panel display of facsimile apparatus 1 according to the present embodiment. As shown in FIG. 11A, touch panel display 3 is attached to main body 2 via hinge section 110. Hinge section 110 is connected with touch panel display 3 at junction 110a and with main body 2 at junction 110b in a pivotable manner. Therefore, the operator can change touch panel display 3 from a first upright posture with screen 3a facing forward as shown in FIG. 11A to a position with screen 3a facing upward as shown in FIG. 11B by raising the bottom of touch panel display 3. Then, the operator can change touch panel to display 3 in a second posture with screen 3a facing upward and covering main body 2 as shown in FIG. 11C by pressing touch panel display 3 downward. With the second posture, dial keys 4 on main body 2 are hidden. In this case, dial screen 40 as shown in FIG. 12A is used. However, when dial keys 4 are available, for example, when the screen is in an upright position, dial screen 40 does not require dial icon section 40a. In such a case, as shown in FIG. 12B, the screen is switched to input result display screen 120 with no dial icon section, giving an enlarged view of the input result of dial keys 4 to improve visibility.

[0112] Switching of screens may carried out when a sensor attached to hinge section 110 of touch panel display 3 detects that touch panel display 3 has exceeded a given angle of elevation.

[0113] The present invention is not particularly limited to the above embodiment. For example, a facsimile apparatus was taken as an example to explain the above embodiment, but the present invention can also include telephones without a facsimile communication function, that is, telephones with an Internet communication function without a printer or scanner. Telephones here include all kinds of communication modes such as portable telephones, PHS, and Internet telephones.

[0114] Moreover, a touch panel display was taken as an example to explain the above embodiment, but the LCD display and touch panel can also be configured separately. Furthermore, an LCD display was taken as an example of display section for the above embodiment, but the display section can also include a CRT display and others. Cursor keys were taken as an example of pointing section for the above embodiment, but the pointing section can also be made up of a track ball, mouse on the like.

[0115] The present invention is not limited to the above described embodiments, and various variations and modifications may be possible without departing from the scope of the present invention.
