All these keys 51-55 are made of a semitransparent material and can be seen in a dark place as they are lighted from the inside of the mobile phone 1 by a key backlight 153 shown in a block diagram of FIG. 2.
Moreover, since the LCD unit 40 is also lighted by a screen light 154 shown in the block diagram of FIG. 2, it is easy to see a screen displayed there. However, when the keys are operated in a bright place, the key backlight 153 is put out so that the power is saved.
FIG. 2 is a view showing an internal circuit block diagram of the mobile phone 1 of which external view is shown in FIG. 1.
A radio wave received by the antenna 10 is picked up by a sending/receiving unit 70 to take out a signal that is sent to a signal-processing unit 80.
Also, the sending/receiving unit 70 notifies a control unit 120 of a call when it arrives.
The signal-processing unit 80 divides a signal sent from the sending/receiving unit 70 into a voice signal and an image or a character signal, and sends the voice signal to an interface unit 90 as well as sends the image signal or the character signal to the control unit 120. The interface unit 90 sends the voice signal sent from the signal processing 80 to a speaker 100 and a voice is output from the speaker 100.
On the other hand, when sending a message, a voice signal picked up by a microphone 110 is sent to the sending/receiving unit 70 via the interface unit 90 and the signal-processing unit 80, and the sending/receiving unit 70 converts the voice signal into a signal to be put on a radio wave and sends it to the antenna 10 to emit it as a radio wave into a space.
In a storage unit 130, various voices and screens have been stored and can be additionally stored.
An LCD unit 40 shown in FIG. 2 corresponds to the LCD unit 40 shown in FIG. 1, and an input operation unit 50 shown in FIG. 2 corresponds to the input operation unit 50 shown in FIG. 1.
The control unit 120 reads out a receipt-waiting screen from the storage unit 130 and displays it on the LCD unit 40 in a receipt waiting state. When notified by the sending/receiving unit 70 of an arrival of a call, in order to indicate such an arrival of a call, the control unit 120 reads put a receipt melody from the storage unit 130 to let the speaker 100 make the sound of the receipt melody via the signal-processing unit 80 and the interface unit 90, as well as uses a light by turning on the green LED 151 of the bicolor LED 150. Further, when notified of an arrival of a call, the control unit 120 turns on the screen light 154 to light up the LCD unit 40 and turns on the key backlight 153 when it is dark around the mobile phone.
Also, the control unit 120 makes calls according to operations in the input operation unit 50, stores various setting conditions to be made according to operations performed on the input operation unit 50 in the storage unit 130, or controls display screens in the LCD unit 40. Further, during a battery (not shown) is being charged up, the control unit 120 indicates a charging state by turning on the red LED 152 of the bicolor LED 150.
FIG. 3 is a view showing changes of menu screens displayed in an LCD unit, made by key operations.

Moreover, when the graphical menu shown in part (E) of FIG. 3 is displayed, the left soft key 51 and the right soft key 52 are pressed, menu screens in part (G) and (I) of FIG. 3 respectively corresponding to the lower left small screen “SETTING” and the lower right small screen (a book-shaped sign) are displayed. Here, except for the receipt-waiting screen shown in part (A) and the graphical menu shown in part (E) of FIG. 3, each screen shown in parts (B), (C), (D), (F), (G), (H) and (I) of FIG. 3 corresponds to the second menu screen according to the present invention.
In each second menu screen, a menu shown in characters as well as a background screen reminding a user of a category that varies with each second menu screen are displayed. By this background screen, without thinking of a category, it is possible for a user by the light of nature to know a category of a menu screen being displayed reading a menu displayed.
After any of the second menu screens is displayed, by operation ways similar to those used in conventional techniques, any of options in a list shown in the menu screen displayed is selected and a process according to the selected option is executed.
FIG. 4 is a flowchart showing a menu screen display routine which is executed in the control unit 120 shown in FIG. 2.
When the mobile phone is turned on, the receipt-waiting screen shown in part (A) of FIG. 3 is displayed in the LCD unit (step a), and whether the menu key (the key 51 shown in FIG. 1) is pressed or not is detected (step b).
If the menu key 51 is pressed, the graphical menu shown in part (E) of FIG. 3 is displayed. And in a state that the graphical menu is displayed, if any of the upper key 54 a, the lower key 54 b, the left key 54 c, the right key 54 d, the decision key 53, the left soft key 51 and the right soft key 52 is pressed (step c, d, . . . i), a menu screen corresponding to the pressed key is displayed (step c2, d2, . . . i2). And in a state that the graphical menu shown in part (E) of FIG. 3 is displayed, if the clear key 55 a is pressed (step j), the flow returns to display of the receipt-waiting screen (step a). In a state that the menu screen of each category is displayed, if the clear key 55 a is pressed (step c3, d3, . . . i3), the flow returns to the graphical menu.
In the present embodiment, as described above, since the graphical menu that displays the small screens reminding a user of each category on the display positions corresponding to the positions of the arranged keys (operation positions of the operation panel) is provided, the user finds by the light of nature which key should be pressed next and operability improves. Also, by keeping the receipt-waiting screen as a background screen in the graphical menu screen, the design of the graphical menu screen becomes better and a user finds in a moment that this is the screen for selecting a category.
Further, also in the menu screens that vary with the category, by displaying a background screen reminding a user of a category that belongs to a menu screen, it is possible to find the category of the displayed menu screen by the light of nature.
The above-described embodiment is an example in which the present invention is applied to a mobile phone. However, the present invention can be widely applied to not only mobile phones but also PHS phones or other portable terminals.
As described above, according to the present invention, operability of a portable terminal can be further improved.
