Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile communication terminal, and more particularly to an arrangement of operation keys suitable for a mobile communication terminal having a game function.
[0002]
[Prior art]
The functions of mobile communication terminals have recently been expanded in various ways, and games can be enjoyed on mobile communication terminals. Examples of mobile communication terminals having a game function are disclosed in Japanese Patent Laid-Open Nos. 10-271562 and 11-88948.
[0003]
Conventionally, in a mobile communication terminal having a game function, a game screen is displayed on a display unit provided in the mobile communication terminal body, and a game is played using a key for performing a telephone function.
[0004]
An example of such a conventional mobile communication terminal is shown in FIG. The main body 11 of the bar-type mobile communication terminal shown in FIG. 4 includes a direction key 12 having four buttons for moving the cursor up, down, left, and right as operation keys for performing a telephone function, an * key 13 and a # key 14. .
[0005]
These direction keys 12, * key 13 and #key 14 are also used for games. The bar-type mobile communication terminal shown in FIG. 4 is an operation key used for a game even in a foldable mobile communication terminal having a flap.
[0006]
[Problems to be solved by the invention]
In the conventional mobile communication terminal described above, the operation key for the telephone function and the operation key for playing the game are common, so if the key is damaged due to intense operation during the game, not only the operation of the game but also the call Operation may be hindered. For example, there may be a problem that a telephone number cannot be searched or a specific number cannot be entered to make a call.
[0007]
Further, since the game operation key and the telephone operation key are on the same plane, there is a possibility that the other keys for the telephone are erroneously operated during the game. Then, when a call is received during a game, there is a possibility that the telephone function may be adversely affected, such as by accidentally hanging up the telephone.
[0008]
The present invention has been made in view of the above points, and the object of the present invention is not to affect the telephone function even if a key used for a function other than the telephone is damaged. It is an object of the present invention to provide a mobile communication terminal that does not have a risk of erroneous operation of other keys for a telephone when a function is used.
[0009]
[Means for Solving the Problems]
The mobile communication terminal according to the present invention is a mobile communication terminal having a function different from the telephone function in addition to the telephone function, wherein the operation key related to the telephone function is arranged in the main body, and the telephone is not related to the telephone function. An operation key related to a function different from the function is placed in a casing covering the operation key related to the telephone function, and when the casing covering the operation key is opened at the time of an incoming call, the function different from the telephone function is interrupted. When a call can be made and the casing covering the operation keys after the call is closed, a function different from the telephone function is resumed .
[0010]
In the mobile communication terminal, a function different from the telephone function is a game function.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
A mobile communication terminal according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a mobile communication terminal according to an embodiment of the present invention. FIG. 2 is a perspective view showing another state of the mobile communication terminal.
[0015]
A flap 2 is rotatably attached to the main body 1 shown in FIGS. 1 and 2, and a game-specific direction key 5 and a game are provided on a surface that becomes the surface of the flap 2 with the flap 2 shown in FIG. 1 closed. Dedicated operation keys 6 and 7 are arranged. The game power switch 8 is arranged at the corner between the front surface and the side surface of the flap 2.
[0016]
Telephone operation keys 4 are arranged on the surface of the main body 1 that appears when the flap 2 shown in FIG. 2 is opened. The display unit 3 provided in the main body 1 is used as an operation guide when used as a telephone, and is used as a game screen when used in a game.
[0017]
As shown in FIG. 2, when the flap 2 is opened, the telephone operation keys 4 appear on the surface and a telephone call can be made. At this time, the microphone hole 10 provided in the flap 2 also appears on the surface, and the microphone can be arranged at the mouth. The game direction key 5 and the game operation keys 6 and 7 can be operated with the flap 2 shown in FIG. 1 closed, and the game can be enjoyed.
[0018]
In this way, when the flap 2 is closed, only the game function is operated, and when the flap 2 is opened, only the telephone function is operated to prevent mutual interference of the functions. That is, since the telephone operation key is covered with the flap 2 when the game function is activated, the telephone operation key is not erroneously activated during the game.
[0019]
When a call comes in during the game, the game is temporarily suspended, and a call can be made by opening the flap 2. The game can be resumed by closing the flap 2 after the call.
[0020]
Further, by arranging the power switch 8 dedicated to the game function on the flap 2, it is possible to prevent the power from being inadvertently turned on in a pocket or a bag. If the display screen is turned off by closing the flap 2 and turning off the power switch 8 dedicated to the game function, current consumption can be saved. If the flap 2 is closed when it is put in a pocket or bag, the telephone operation keys are hidden by the flap 2 and a malfunction is prevented.
[0021]
FIG. 3 shows an example in which the game direction key 5 in the above embodiment is changed to a cross-shaped game direction key 9. As described above, since the game-dedicated key is not used as a telephone function, it is possible to make the game operation feel similar to the original game machine as an arbitrary shape.
[0022]
【The invention's effect】
According to the present invention, for example, in a mobile communication terminal having a game function and a telephone function as in the embodiment, the game dedicated key is completely independent from the telephone operation key. Even if it is damaged, the telephone function is not affected. Further, interference with each other's functions is prevented, and there is no possibility of erroneous operation during key operation.
