DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

(1) Overall Configuration (1-1) Device Main Body First, the overall configuration and circuit configuration of the portable telephone device 1 will be described with reference to FIGS. 1 and 2. The mobile phone device 1 is composed of a device body 2 and an arm microphone 3 attached to a side surface of the device body 2 so as to be rotatable (openable and closable). Therefore, the size of the mobile phone device 1 can be further reduced by closing the arm microphone 3 except when in use.

The arm microphone 3 has a function of controlling on-hook or off-hook in conjunction with an opening / closing operation, and a function of invalidating operations other than a specific key in the closed state (hereinafter,
Key lock function) is provided. Incidentally, this key lock state can be released by opening the arm microphone 3. This makes it possible to prevent erroneous calls and erroneous calls due to malfunctions.

On the other hand, the apparatus main body 2 is provided with various operation keys and processing circuits. Here, on the surface of the device main body 2, in addition to the speaker 4 paired with the arm microphone 3, a liquid crystal display 5 and a plurality of operation keys 6 to which various functions are assigned are provided, and inside thereof, these are input / output devices. The CPU 7 is built in. The CPU 7 controls the liquid crystal display 5 via the liquid crystal display driver 5A, and displays information according to an instruction input from the operation keys 6 in a font of an appropriate size.

Here, the CPU 7 operates based on the program stored in the ROM 8 and the data read into the RAM 9. Further, the CPU 7 controls the transmission / reception circuit unit 10,
Information is transmitted / received to / from another communication terminal via the antenna 11 connected to this. Because of the CPU
A card socket 13 is connected to the subscriber ID card 7 and a subscriber ID card 12 (SIM in the case of the embodiment)
All the management information about the subscriber is read from the (Subscriber Identity Module) card 12) and used for control.

By the way, on the display surface of the liquid crystal display 5 used in this embodiment, pixels of 32 dots × 97 dots are arranged vertically and horizontally in a matrix form so that information can be displayed by two kinds of fonts. Has been done. One is a small font that displays one character in vertical 5 dots × horizontal 7 dots as shown in FIG. 3, and one is 1 as shown in FIG.
It is a large font that displays characters 15 dots vertically x 8 dots horizontally. Therefore, if small fonts are used, 4 characters vertically and 16 horizontally
Characters can be displayed, and if a large font is used, 2 vertical characters and 10 horizontal characters can be displayed.

In principle, the large font is used to display characters input by the user, and the small font is used to display a message or the like on the device side. However, when the number of characters input by the user exceeds a predetermined number (20 characters), the font size can be switched from the large font to the small font.

A display example is shown in FIG. First, the number of input characters is 1
Characters entered by the user are displayed in large font one after another in the lower row of the message "input dial No" displayed in the upper row while the number of characters is 0 or less. When the number of input characters exceeds 10, the first 10 characters are displayed in large fonts in the upper row where the messages have been displayed until then, and the 11th and subsequent characters are displayed in large fonts in the lower row. Eventually, the number of input characters reaches 20, and if all the input characters are exceeded, small input fonts are displayed.

Since the font switching function is provided in this manner, large characters can be input while checking the input contents while the number of input characters is small, and erroneous input can be reduced. Further, even if the number of characters is large, the input information for the same item can be confirmed on one screen, so that the input content can be easily grasped.

(1-2) Operation Keys Next, the operation keys 6 provided in the apparatus body 2 will be described. In the case of this embodiment, the operation keys 6 are the following ten keys. Power key 6A, number keys 6B of "0" to "9", "#" key 6C, "*" key 6D, send key 6E, end key 6F, menu key 6G, clear key 6H, recording key 6I and jog dial 6J 10 It is an individual. Of these, eight operation keys 6A to 6H are arranged on the front surface of the apparatus body 2, and the remaining two operation keys 6I and 6J are arranged on the side surface of the apparatus body 2.

The main functions assigned to each operation key are as follows. The power key 6A is a key used to turn on the internal circuit of the apparatus main body 2, and the power is turned on by the first pressing operation and turned off by the second pressing operation. . However, power key 6A
For 30 seconds after the power is turned on, the personal identification number (PIN: Personal) is displayed by the user.
When the ID number) is not input, the CPU 7 detects this and automatically turns off the power. This prevents the power from being left on due to a malfunction.

Next, the ten numeric keys 6B will be described. These ten numeric keys 6B are used for inputting and selecting numbers, and also for inputting alphanumeric characters. In the case of this embodiment, a plurality of alphanumeric characters are assigned to the eight numeral keys "2" to "9" excluding the "0" and "1" keys, respectively, so that the alphanumeric characters can be input by these. There is. For example, "2" means "a"
"D" to "f" are assigned to "c" and "3", and an alphabet is similarly assigned to other keys.

When inputting an alphabet, pressing the same key once will input the first character, pressing it twice will input the character on the second side, and pressing it three times will input the third character. It is designed so that you can enter in order. Further, this numeric key 6B can be used to select a display item, and by pressing and holding it on the telephone directory list display screen for a predetermined time (1 second), it is possible to instruct to start calling to the other party corresponding to the number (so-called shortening). The dial function can be realized).

The send key 6E is used for instructing the start of calling to the other party selected on the telephone directory list display screen, and is also used for calling the past dial history.
The end key 6F is used to instruct the end of the call. Incidentally, the end of the call can also be instructed by closing the arm microphone 3.

The menu key 6G is a key used to switch the screen displayed on the liquid crystal display 5 between the initial screen and the menu screen. For example, assuming that the screen shown in FIG. 6A is the initial screen, when the menu key 6G is pressed on the initial screen, the display can be switched to one of the menu screens shown in FIG. 6B, which will be described later. By the scroll function, it is possible to switch to a screen as shown in FIG. 6C so as to turn the pages one by one. On the other hand, if the menu key 6G is pressed while the menu screen is displayed, any screen can immediately return to the initial screen. By using the clear key 6H, it is possible to return to the previous screen by turning the page one screen at a time as shown in FIG.

The menu key 6G is assigned the function as the only operation key capable of canceling the key lock state. That is, as shown in FIG. 8, even when the arm microphone 3 is closed, the menu key 6G can be pressed to exit the key lock state and shift to the key active state. On the other hand, if the menu key 6G is pressed while the arm microphone 3 is closed and the menu screen is displayed, the key lock state can be restored.

Incidentally, when the user does not perform any operation on the menu screen for 30 seconds, the CPU 7 detects the fact and automatically closes the menu screen and returns to the initial screen. There is. At this time, when the arm microphone 3 is closed, the key lock state is returned from this state. This can prevent malfunction.

The recording key 6I is a key used to control recording and reproduction of a conversation during a call, and the device main body 2
The device body 2 so that you can operate it with your hand holding
Is attached to the opposite side of the upper surface of the arm microphone 3.

Finally, the jog dial 6J having a central function among the ten operation keys will be described. The jog dial 6J is provided on the upper side of the side of the apparatus main body 2 opposite to the arm microphone 3 and in the vicinity of the speaker 4, and can be operated as it is by the hand held like the recording key 6I.

The jog dial 6J is designed so that it can be operated independently in the circumferential direction and the radial direction. As shown in FIG. 9, the jog dial 6J can be operated in the circumferential direction about the rotation axis O (arrows A and B). A disk-shaped member (which constitutes a rotary encoder) that rotates in the direction of
And D), and a slide plate (not shown) and a slide switch SW. Here, the slide plate and the slide switch SW are biased in the C direction.

Incidentally, the rotary shaft O is fixed to the slide plate, and when the jog dial is pushed in the direction of arrow D, the rotary encoder is slid together with the slide plate to push down the switch SW to turn it on. It is designed to be controlled. CPU7 is this switch SW
Whether or not the jog dial 6J has been clicked is detected by detecting the on / off state of.

Incidentally, the rotary encoder, which is slid integrally with the slide plate, has two discs 6 as shown in FIG.
It is composed of J1 and 6J2. Of these, the disc 6J1 is a movable member laminated on the upper surface of the disc 6J2, and is attached so as to be rotatable relative to the disc 6J2 fixed to the slide plate. Here, a pair of counter electrodes 6J21 is provided on the movable side disk 6J1. When the counter electrode 6J21 is assembled, the disc 6
20 sets of counter electrodes 6J2 provided along the circumference of J2
It is designed to be able to slide in contact with 2. Incidentally, the counter electrode 6J22 provided on the fixed-side disk 6J2 is formed such that the positions on the inner peripheral side and the outer peripheral side are slightly shifted.

Accordingly, when the jog dial is turned in the direction of A, the potential output from the counter electrode is such that the potential on the inner peripheral side first falls to the ground potential as shown in FIG. 11 (A).
When it is turned in the direction of B, as shown in FIG. 11 (B), the potential on the outer circumference side first falls to the ground potential, and it is detected which of the potential on the inner circumference side and the potential on the outer circumference side falls first. Thus, it is possible to detect the rotating direction of the jog dial. The amount of rotation of the jog dial can be detected by counting the number of pulses output from the electrodes on the outer peripheral side.

Next, a typical operation example using the jog dial 6J will be described. First, when the list screen is displayed on the liquid crystal display 5, the cursor K displayed on the liquid crystal display 5 can be moved up and down by up or down operating the jog dial 6J in the circumferential direction. You can select one of the following. Incidentally, if the jog dial 6J is pushed in the radial direction in this state (hereinafter referred to as a click), the CPU 7 can be instructed to read out detailed information on the item at which the cursor K is located.

When the telephone directory list is displayed,
The call start can be instructed by pressing and holding the jog dial 6J for a predetermined time. Incidentally, the volume of the volume (listening volume) can be adjusted by rotating the jog dial 6J in the circumferential direction during a call. Also, it is possible to mute by clicking the jog dial 6J during a call. A typical example of use of the jog dial 6J when making a call is summarized in a flow chart as shown in FIG.

That is, by clicking the jog dial 6J while the list screen such as the telephone book or redial screen is displayed, detailed information of the selected item can be displayed on the screen, and in this state, the jog dial 6J can be displayed for a predetermined time. If you continue to click, you can automatically start calling to the destination displayed at the cursor position. On the other hand, if the jog dial 6J is rotated and the cursor K is operated up or down, the original list screen can be returned.

(2) Calling / Editing (2-1) Calling In this section, various calling methods prepared in the portable telephone device 1 will be described. As shown in FIGS. 13 and 14, the mobile telephone device 1 is provided with five calling methods.
These can be classified into a calling method using a telephone directory list, a calling method using a redial function, a calling method of directly inputting a telephone number, and a calling method using a speed dial function. First, a method of making a call from the phonebook list screen will be described.

(2-1-1) Calling from the telephone directory list screen A state in which the arm microphone 3 is opened, or an external microphone is connected to the apparatus body 2, or a hands-free kit is connected to the apparatus body 2. When the jog dial 6J is clicked in any of the above states, the display on the liquid crystal display 5 is switched from the initial screen of FIG. 15 (A) to the telephone directory list screen shown in FIG. 15 (B).

Here, as shown in FIG. 16, the telephone directory list has a display field classified by frequency of use in which address numbers "1" to "9" and registered destinations with high frequency of use are displayed as a set. , All registered destinations are in descending order (eg AB
It is a descending order display field (including those already registered in the address numbers “1” to “9”) displayed in C ... (order).

Immediately after switching to the telephone directory list, the position of the cursor K is located at the top of the display item displayed on the liquid crystal display 5, that is, the address number "1". If the jog dial 6J is rotated downward in this state, the cursor K can be moved to “2”, “3”, and so on. On the contrary, if it is rotated upward, it is reversed from the bottom of the descending order display column. The cursor K can be moved in the direction, that is, ZYX ....

Incidentally, as a method of selecting the other party by moving the cursor K, there are a method of inputting an address number and a method of inputting an alphabet in addition to the operation using the jog dial 6J. For example, if the telephone number of the other party is already registered in one of the address numbers of the "1" to "9" keys and the address number is known, pressing the key of that number jumps the cursor K by one foot. Can be moved to. FIG. 17 shows an example thereof.

When the list screen is a display screen in the order of alphabetic characters, the cursor K can be moved to the corresponding alphabetic characters by the numerical keys "1" to "9". For example, pressing "2" can move the cursor K to "a", and pressing "3" can move the cursor K to "d". If there is no name that starts with "d", move the cursor K to the name that starts with "e" and display it. If there is no name that starts with "e", the name that exists after that is displayed. The cursor K is moved to the closest name and displayed.

Here, as shown in FIG. 15C, the following calling procedure will be described assuming that the cursor K is moved to the position of "Jack" registered in the address number "5". There are several methods for making a call from this state. Here, a method of using the jog dial 6J will be described. If you click on the jog dial 6J in this state,
The display screen is switched to the detailed information display column as shown in FIG. Then, if the jog dial is kept clicked for 1 second in this state, a call is started. At this time, the liquid crystal display surface blinks as shown in FIG.

If it is desired to change the call destination while the detailed information is displayed as shown in FIG. 15D, the jog dial 6J may be rotated upward or downward. For example, when the jog dial 6J is rotated upward on the display screen of FIG. 18B, the display screen can be returned from the detailed information screen to the list screen belonging to the next higher layer. However, the position of the cursor K is moved to the item one item higher than the partner whose detailed information was displayed. That is, FIG.
As shown in (C), the cursor K has the address number "5".
Instead of "Ellis" of "Jos" of address number "4"
hn ”.

Incidentally, if there is no operation for a predetermined time (30 seconds) while the detailed information is being displayed as shown in FIG. 15D, the telephone directory list is closed because no call is made. A function of returning to the initial screen shown in FIG. This prevents erroneous transmission even if the key that may initiate a call is accidentally pressed when the mobile phone device 1 is carried in a bag or the like with the detailed display screen. By the way, this function also works when the list screen is displayed.

In addition to these methods, there is also a calling method of pressing the send key 6E on the display screen shown in FIG. 15D as a method of starting a calling from the telephone directory list screen. These are methods of starting a call after displaying detailed information of the other party, but the mobile phone device 1 is also provided with a function of starting a call directly from the list screen. For example, in FIG.
By pressing the send key 6E in the state of the display screen shown in (C), it is possible to immediately start calling to the communication destination where the cursor K is located. Similarly, the call can be started immediately by pressing the numeric key corresponding to the communication destination for 1 second.

(2-1-2) Calling from the redial list screen Next, the transmission operation from the redial list screen will be described with reference to FIGS. 13 (G) to 13 (J). This redial list screen can be opened by pressing the send key 6E in the initial screen state. That is, when the send key 6E is pressed on the screen of FIG. 13 (A), the name of the other party (when calling from the phonebook list) or the telephone number (when manually entering the telephone number), which is the call destination in the past, is displayed. 13 (G) will be displayed. In this state, the operation selected by the call destination and the operation when making a call are the same as those when making a call from the telephone directory list.

If there is no operation for a predetermined time (30 seconds) with the list shown in FIG. 13G displayed, the telephone directory list is closed without calling. A function of returning to the initial screen shown in (A) is also provided. As a result, even if the portable telephone device 1 is carried in the bag or the like as it is on the detailed display screen and a key input that happens to initiate a call happens by mistake, an erroneous call is not made.

Further, the portable telephone device 1 is provided with a function of displaying information about how long a call has been made to the communication destination last time and the present call time. For example, in FIG.
The previous call time is displayed as "4:25" as shown in (H), and the current call time is displayed as "0:00:55" as shown in FIG. 13 (J).

(2-1-3) Calling by Inputting Telephone Number In this case, the telephone number of the other party may be input as it is at the stage of the initial screen of FIG. 13 (A). Then, the display screen shifts from the state of FIG. 13A to the state of FIG. 13K, and the telephone number input by the user is displayed in large font. If this number is acceptable, the send key 6E is pressed to start blinking the screen as shown in the screen of FIG. 14L, and the call to the other party is started.

(2-1-4) Calling by Speed Dial Two types of calling methods are prepared for this calling method.
One is a calling method by pressing the numeric key 6B for a predetermined time, and the other is a calling method using the numeric key 6B and the "#" key.

First, when only the numeric keys 6B are used (see FIG.
4 (O) to FIG. 14 (P) will be described. The user keeps pressing the numeric key 6B corresponding to the address number of the other party who is trying to make a call, for example, for one second while the display screen is in the state of FIG. By doing so, the screen displayed on the liquid crystal display 5 is immediately switched to the detailed display screen and the call is started as it is.

Next, the case where the numeral keys 6B and the "#" key 6D are used (FIGS. 13 (Q) to 14 (S)) will be described. The user switches the screen to the detailed display screen by pressing the “#” key 6D after pressing the number key 6B corresponding to the address number of the other party to make a call on the display screen shown in FIG. 13 (A). And in this state send key 6
The call is initiated by pressing E.

(2-1-5) Registration / Editing Next, a method of registering a telephone number or the like in these telephone directory lists and an editing method will be described. First, press the menu key 6G to open the menu screen, and select "Telbook edit" on this screen so that the telephone number or the like can be registered. There are two ways to register from here. The first is a method of designating a new registration item and inputting a new telephone number. If the user wants to register a new destination,
The jog dial 6J is operated to move the cursor K to the "new registration" item, and in that state, click the jog dial 6J (FIG. 19 (B)).

Then, the display screen is switched to that shown in FIG. 19C, and the characters for prompting the input of the name are displayed. When the user operates the numeral keys 6B in this state, the input characters are displayed in a large font alphabet. If it is acceptable to register the characters entered here, the user clicks the jog dial 6J and moves to the registration screen of the subsequent telephone number. If the entered telephone number is registered, the jog dial 6J can be clicked again. Then, the newly input name or the like is registered in the empty area of the telephone directory list as shown in FIG.

Another method is to select an unregistered address number and register the name. In this case, FIG.
As shown in (A) and (B), the cursor K is moved to an unregistered address number. In the case of this example, it is "7". If you click on the jog dial 6J in this state,
On the liquid crystal display 5, characters for prompting the input of a name are displayed.

After that, the destination name is input by operating the corresponding numeric key 6B in the same manner as the registration procedure described above, and if correct, click the jog dial 6J to register. Then, as shown in FIG. 20D, by inputting a telephone number according to the instruction displayed on the screen and clicking the jog dial 6J in the same manner, the inputted telephone number can be registered. These are the procedures for registering the phone book list.

On the other hand, at the time of editing, FIGS. 21 (A) and 21 (B)
The cursor K may be moved onto the name to be edited as shown in, and the jog dial 6J may be clicked.
In this way, when the already registered item is selected, the edit mode is entered. When the edit mode is entered, the name of the destination to be edited and the edit contents (change (edit), delete (delete), swap (swap)) are displayed on the screen. The user selects the editing content by operating the jog dial 6J here.

For example, when the deletion is selected, the display screen is a screen for confirming again whether or not the registered contents can be deleted as shown in FIG. At this time, if "Yes" is selected, the erase operation is executed. On the other hand, when the replacement is selected, the display screen is switched to that shown in FIG.
The display screen prompts the user to input which address number should be replaced with the registered content. When the address number to be replaced is input and the jog dial 6J is clicked, the replacement operation is executed, and the registered contents after the replacement are shown in FIG.
It is displayed like (G). In this example, "8" and "6" are interchanged.

When "Change" is selected, the screens for accepting changes for each item are displayed in FIGS. 21H and 21I so that both the destination name and the telephone number can be changed.
Are sequentially displayed as shown in FIG. When the jog dial 6J is clicked in this state to confirm the changed contents, the display screen is switched to that shown in FIG.

(3) Menu screen (3-1) Item contents Finally, the menu screen displayed when the menu key 6G is pressed will be described. The menu screen is hierarchically configured, and the user can descend to a lower hierarchy (sub menu screen) by clicking the jog dial 6J. 22. Here, FIG. 22 shows the top-level menu screen W1 prepared in the mobile phone device 1.
