Description

  The present invention relates to a mobile communication device. More specifically, the present invention relates to a mobile communication device which is a mobile phone used for a wireless call as a so-called mobile phone and has an additional function.

  With advances in communication speed and processing speed, mobile phones have advanced functions other than voice calls such as cameras, data communication, and games. In particular, since the game function is rapidly advanced in a game-dedicated machine, the game function mounted on the mobile phone is required to be further advanced. In addition, the performance of the central processing unit mounted on the mobile phone is improved and the resolution of the liquid crystal is increased, and game software released for home video game consoles has been ported to the mobile phone.

  As game functions become more sophisticated, enhancement of the user interface in hardware is unavoidable. Specifically, it is required to implement unique buttons and switches used for operating the game, and to expand the display device that displays the game status reflecting the input. However, in the case of a voice terminal device that is supposed to be carried and used, the absolute dimensions thereof are limited, and therefore, it is limited from the surface area that can be mounted to enhance hardware resources.

  Patent Document 1 below describes that in a foldable mobile phone device, a portable game machine is formed by using substantially the entire folded surface. Thereby, operation as a game machine and operation as a mobile phone are separated, and each operability is improved.

  The following Patent Document 2 describes a support board that is a game controller adapter that is used by being mounted on a mobile phone. Thereby, the operation of the game can be improved and the limited storage capacity, processing speed, etc. of the mobile phone can be compensated.

  Patent Document 3 listed below describes a mobile phone having a flip that can be opened and closed, and in the form of a portable game machine when the flip is closed. Thereby, the operativity as a game machine and the operativity as a mobile phone can be made compatible.

  Patent Literature 4 below describes a game controller that is used by being mounted on a mobile phone. Thereby, when the game is executed, high operability that cannot be obtained by the operation unit of the mobile phone can be obtained.

  Patent Document 5 listed below describes a mobile phone that includes a plurality of folded display units and can expand a display area by developing the display unit when playing a game. Thereby, it is possible to play a game while displaying more information, and when it is folded, it becomes small.

  Patent Document 6 below describes that a movable plate folded in a housing is provided and a game key is provided on the movable plate. Thereby, the operativity in a game can be improved, without impairing the portability and operativity as a mobile phone.

Patent Document 7 below describes that a pair of flips having a half length with respect to the half length of the main body is provided, and a key operation unit for a game is provided in each flip. Further, Patent Document 8 below describes a structure in which a game operation unit is provided with a structure that slides and projects sideways. With these structures, it is possible to improve the operability in the game by arranging the key operation units on both sides of the display unit.
JP 2001-136250 A JP 2002-123353 A JP 2002-330198 A JP 2003-111976 A JP 2004-179817 A JP 2005-101784 A JP-A-2005-244385 JP 2007-067892 A

  As described above, many keys of the mobile phone are densely arranged to deal with various operations such as inputting numbers when making a call and inputting characters when sending a mail. For this reason, it cannot be said that it is the optimal arrangement | positioning with respect to operation which requires a user's quick reaction like a game.

  On the other hand, as described in Patent Document 1 and Patent Document 3, in the case of a structure that can take the form of a portable game dedicated machine, the operability and display area are limited with respect to the consumer game dedicated machine. The operability is only as good as a portable game machine. In exchange for this, the operability as a mobile phone is lowered.

  Further, as described in Patent Document 2 and Patent Document 4, in a structure in which an adapter used exclusively for operating a game is added to a mobile phone, the portability of the mobile phone is lowered when the adapter is attached. In addition, since the display area of the display unit of the mobile phone does not change, just because the operability is improved, an advanced game cannot be executed. Furthermore, the removed adapter must be carried separately from the mobile phone.

  Furthermore, the structure shown in Patent Document 5 combines a plurality of display members for the purpose of expanding the area of the display region. For this reason, although the total area of a display part increases, the area of one display part does not change. Further, game software that can be executed in such an environment is limited to game software having a specific specification that distributes information to a plurality of display units. Furthermore, since the structure as a mobile phone becomes complicated, it is disadvantageous in terms of manufacturing cost and durability.

  Furthermore, the structure described in Patent Document 6 increases the number of parts and increases the manufacturing cost as a mobile phone, and the operation unit is small, so the operability as a game machine does not improve much. . Further, since the display unit is not enlarged, the game that can be executed is the same as that of other mobile phones.

  Further, the structures described in Patent Document 7 and Patent Document 8 use a plurality of hinges, sliders, and the like, so that productivity is low and manufacturing cost is high. Further, the area of the display unit is not enlarged. Thus, a voice terminal device having portability as a mobile phone, operability in a game, and display performance in a game has not been realized yet.

  Therefore, in order to solve the above problems, as a first embodiment of the present invention, there is a mobile communication device that communicates with a base station by wireless communication, and is connected to each other at a longitudinal edge and intersects the longitudinal direction. A pair of housings that can be opened and closed with respect to each other, an outer operation unit that can be operated when the housing is closed, a speaker and a microphone arranged in a longitudinal direction on an outer surface when the housing is closed, and a housing A mobile communication device is provided that includes an inner display unit that is arranged on one of inner surfaces that appear when the body is open and displays an image.

  It should be noted that the above summary of the invention does not enumerate all the necessary features of the present invention. Further, a sub-combination of these feature groups can be an invention.

  The present invention will be described below through embodiments, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for solving the problem.

  FIG. 1 is a perspective view showing an appearance of a game mobile phone 100 according to one embodiment. As shown in the figure, the game mobile phone 100 has a front case 120 and a back case 110, and has a substantially rectangular parallelepiped shape in a state where these are stacked. In addition, a display area 125 and an operation area 123 arranged side by side in the longitudinal direction are provided on the outer surface of the front side casing 120 in a state of being overlapped with the back side casing 110.

  The display area 125 and the operation area 123 are formed on one touch panel 121. The touch panel 121 has a structure in which a matrix switch for detecting contact or approach to the display panel is provided on the surface of a display panel such as a liquid crystal display device. Thereby, the touch panel 121 functions as a display device and also functions as an operation device. In addition, by changing the display image and the function corresponding to the display image in cooperation with each other, it is possible to cope with various operations using one touch panel 121. In addition, the entire surface of the touch panel 121 can be used as a display unit.

  In the state shown in FIG. 1, approximately the upper half of the touch panel 121 is used as the display area 125. An operation of generating a code as a numeric keypad by displaying a numeric keypad image on the lower half of the touch panel 121 and detecting contact or approach to the area where the image of each button of the numeric keypad is displayed. Region 123 is formed. The “ten-key” includes a key for generating a symbol code, a control code and the like in addition to a key for generating a numeric code.

  Further, on the surface of the front case 120 of the game mobile phone 100, a speaker hole 129 and a microphone hole 127 are arranged above the touch panel 121 (on the display area 125 side) and below (on the operation area 123 side). The speaker hole 129 communicates with the speaker unit built in the front case 120. Thereby, the sound generated by the speaker can be heard through the speaker hole 129. The microphone hole 127 communicates with a microphone unit built in the front case 120. Thereby, the voice uttered toward the microphone hole 127 can be converted into an electrical signal by the microphone unit.

  Furthermore, a hinge member 132 is provided between the front housing 120 and the back housing 110 at the edge in the longitudinal direction, that is, the left side surface in the drawing. One of the front housing 120 and the back housing 110 can be opened with respect to the other with the hinge member 132 as an axis. Thereby, the inner surfaces of the front case 120 and the back case 110 can be exposed.

  FIG. 2 is a perspective view showing a state in which the game mobile phone 100 shown in FIG. 1 is opened about the hinge portion 130 as an axis. As shown in the figure, the hinge member 132 forms a hinge part 130 along the longitudinal edges of the front side casing 120 and the back side casing 110, and the front side casing 120 is horizontal with respect to the hinge part 130. Open in the direction.

  As a result, the inner surface hidden between the front housing 120 and the back housing 110 is exposed. In the example shown in FIG. 2, the back housing 110 has a cross key 112, an inner numeric keypad 114, and a soft key 116 on the inner surface. Here, as in the case of the game dedicated machine, the cross key 112 is arranged on the left side and the soft key 116 is placed in the use state of the game, that is, in the posture in which the front case 120 is up and the back case 110 is down. Arranged on the right side. Thereby, compatibility of operation with a game exclusive machine can be maintained. The inner numeric keypad 114 is disposed between the cross key 112 and the soft key 116. The cross key 112, the inner numeric keypad 114, and the soft key 116 are examples of a limit switch group, a numeric keypad, and an independent switch group, respectively.

  FIG. 3 is a diagram showing the shape of the game mobile phone 100 when the front case 120 and the back case 110 are opened widely. FIG. 4 is a plan view showing a state in which the front side case 120 and the back side case 110 are fully opened until the angle between them is 180 °. As shown in these drawings, in the rear housing 110, the inner operation unit including the cross key 112, the inner ten key 114, and the soft key 116 is exposed to the whole. Further, a large inner display portion 122 having substantially the same area as the inner surface is exposed on the inner surface of the front housing 120.

  Further, in the state shown in FIG. 3, the orientation of the game mobile phone 100 is changed so that the longitudinal direction of the front case 120 and the back case 110 is horizontal. Further, the inner operation unit becomes substantially horizontal on the front side, and the inner display unit 122 stands on the back side. Therefore, when the user naturally holds the game mobile phone 100 with both hands, the back side housing 110 is supported from below with fingers other than the thumbs of both hands, and the buttons on the inner operation unit can be operated with the thumbs of both hands. .

  In the game mobile phone 100 as described above, when one of the top, bottom, left, and right ends of the cross key 112 is pressed down, the cross key 112 generates a unique code corresponding to the pressed position. The tip of the cross key 112 is formed by a switch group having an electronic or mechanical restriction relationship that can be pushed down exclusively, and generates a single code corresponding to one of the tips. With such a structure, when a game is operated, it is possible to input an object or sprite specification, a movement direction specification, and the like by natural operations.

  On the other hand, the soft keys 116 can be depressed independently or simultaneously. A code generated when the soft key 116 is pressed is defined by software executed at that time. In other words, the soft key 116 generates a different code depending on the software to be operated.

  In view of the operation method as described above, the cross key 112 and the soft key 116 that are frequently operated when playing a game are preferably arranged in the vicinity of the side edge in the longitudinal direction of the back housing 110. Thereby, when the user naturally holds the game mobile phone 100, the cross key 112 and the soft key 116 can be easily operated with the thumb.

  On the other hand, the inner numeric keypad 114 having a low operation frequency when playing a game is arranged between the cross key 112 and the soft key 116. The numeric keypad 114 has the same functions as numeric keys provided on other mobile phones, such as inputting numbers and characters. Further, a speaker hole 129 and a microphone hole 127 are also opened on the inner surface of the front case 120 so that the ten key 114 can be used as a mobile phone. The speaker hole 129 and the microphone hole 127 communicate with the speaker unit and the microphone unit, respectively, and can make a call from the inner surface side of the front case 120.

  As described above, in this game mobile phone 100, when the front side case 120 and the back side case 110 are opened, the area exceeding the display area 125 formed in the front side case 120 shown in FIG. The inner display unit 122 having the above can be used. Further, the inner operation unit has a layout according to the game dedicated machine. Therefore, it is possible to play a game with good operability by referring to the abundant information displayed on the wide inner display section 122.

  FIG. 5 is a perspective view showing an appearance of a game mobile phone 101 according to another embodiment. The game mobile phone 101 is drawn in an already opened state.

  As shown in FIG. 5, the game mobile phone 101 also includes an inner display portion 122, a speaker hole 129, and a microphone hole 127 on the inner surface of the front case 120. Further, it is common with the game mobile phone 100 in that an inner operation portion including a cross key 112, an inner numeric keypad 114, and a soft key 116 is provided on the inner surface of the back housing 110.

  Thereby, it is possible to play a game with good operability while displaying abundant information on the wide inner display section 122. Note that the cross key 112 of the game mobile phone 101 is independently provided with a determination key 111 in the center thereof.

  Further, in the game mobile phone 101, the soft key 116 is disposed at the bottom of the depressed portion 115 formed on the inner surface of the back side housing 110. The depth of the depressed portion 115 is about the same as the thickness of a numeric keypad 114 described later, and the operability of the soft key 116 is not lowered.

  On the other hand, the numeric keypad 114 is formed as a panel-like unit and is accommodated in the recessed portion 115. The front surface of the numeric keypad 114 is located on the same plane as the inner surface of the back housing 110, and maintains the same operability as the game mobile phone 100. Further, the numeric keypad 114 can be moved horizontally along the guide rail 113 formed on the side wall of the depressed portion 115, as will be described later.

  FIG. 6 is a perspective view showing another state of the game mobile phone 101. As shown in the figure, here, the numeric keypad 114 is moved to the right in the figure. As a result, the numeric keypad 114 is positioned in the vicinity of the right end of the inner surface in the longitudinal direction of the back housing 110. The soft key 116 is covered with the numeric keypad 114.

  The game mobile phone 101 has a slide detection unit 222 (see FIG. 7) that detects the movement of the numeric keypad 114 inside the guide rail 113. Thereby, when the movement of the numeric keypad 114 is detected, the application activated and executed on the game mobile phone 101 is switched to an application suitable for the layout of the inner operation unit to which the numeric keypad 114 has moved. In other words, the operation assigned to the operation is started and executed by the operation of moving the numeric keypad 114.

  In the example shown in FIG. 6, a mail control unit 234 described later is executed on the inner display unit 122 with the numeric keypad 114 moved to the side, and a screen for editing an email is displayed. In this case, since the inner display unit 122 is wide, the edited content of the reply text and the received text to be referred to can be displayed together. In addition, it can be used for various purposes such as displaying other information such as dictionaries, translations, and address books.

  Further, since the numeric keypad 114 has moved to the vicinity of the edge, it becomes easy to operate. Furthermore, by using the cross key 112 and the enter key 111 as modifier keys, it is possible to speed up character input using the numeric keypad 114.

  That is, in the game mobile phone 101 in the state shown in FIG. 6, the five types of modifier keys including the cross key 112 and the enter key 111 become effective. Thus, 60 types of character codes can be generated by pressing any one of the twelve numeric keys 114 while pressing any one of the cross key 112 and the enter key 111. Therefore, for example, in kana input, all kana can be input in one stroke.

  In the input method as described above, one character code is generated by one operation of simultaneously pressing two keys. Therefore, the input speed can be improved as compared with the input method in which the character code is selected according to the number of times one key is continuously pressed.

  It should be noted that the cross key 112 is operated independently when performing Kanji conversion of characters input with the cross key 112, editing of a character string, or the like. That is, in the game mobile phone 101, the cross key 112 generates a unique code when pressed alone without pressing down the numeric keypad 114. This code is assigned to operation instructions such as conversion, cursor operation, confirmation, and deletion, and can edit input characters.

  FIG. 7 is a diagram schematically showing the internal structure 200 of the game mobile phone 101 having the function of the inner operation unit as described above. As shown in the figure, the game mobile phone 101 includes a key input determination unit 210 that generates a code based on a combination of inputs from the cross key 112 and the numeric keypad 114, a switching unit 220 that switches a result of an operation on the numeric keypad 114, An application control unit 230 that controls an application and an output control unit 240 that controls a speaker and the like are provided.

  The key input determining unit 210 determines whether or not the cross key 112 and the numeric keypad 114 are operated simultaneously. Thus, when the cross key 112 is pressed alone, a control code unique to the cross key 112 is generated. When the cross key 112 and the numeric keypad 114 are pressed simultaneously, a character code is generated. The code output from the key input determination unit 210 is input to the application control unit 230 and the output control unit 240 via the switching unit 220.

  The switching unit 220 includes a slide detection unit 222 and a case opening / closing detection unit 224. The slide detection unit 222 detects a slide operation when the numeric keypad 114 is moved along the guide rail 113. Further, the housing open / close detection unit 224 detects whether the back housing 110 and the front housing 120 are opened based on the state of the hinge unit 130.

  The application control unit 230 controls an application executed on the game mobile phone 101 in accordance with an input from the switching unit 220. In the example illustrated in FIG. 7, the game mobile phone 101 includes a call control unit 232, a mail control unit 234, and a game control unit 236 as applications.

  The output control unit 240 causes the speaker to generate sound in response to the input from the switching unit 220. Further, the image is displayed in the display area 125 of the touch panel 121 and the appropriate area of the inner display unit 122.

  When the case is opened in the game mobile phone 101 having the internal structure 200 as described above, an image is mainly displayed on the inner display unit 122 according to an instruction from the case opening / closing detection unit 224. Accordingly, the input to the cross key 112 and the numeric keypad 114 is reflected on the inner display unit 122.

  Further, when the slide detection unit 222 detects that the numeric keypad 114 is positioned at the center in the longitudinal direction of the back side casing 110 in a state where the casing is opened, the cross key 112 and the soft key 116 are displayed. Is transferred to the game control unit 236. In this case, the key input determination unit 210 generates a control code unique to the cross key 112 in response to an input to the cross key 112. In this way, the user can play a game with almost the same operability as a dedicated game machine using the inner display unit 122, the cross key 112, and the soft key 116.

  On the other hand, when the numeric keypad 114 moves to the right while the housing is open, the application control unit 230 activates the mail control unit 234 and executes its function by the slide detection unit 222 that detects the movement. When the cross key 112 and the numeric keypad 114 are pressed at the same time, a character code is generated by the key input determination unit 210 and passed to the mail control unit 234. On the other hand, when the cross key 112 is pressed alone, a character code is generated by the key input determination unit 210 and passed to the mail control unit 234. Thus, as already described, high-speed mail input and editing can be performed using the inner display unit 122, the cross key 112, and the numeric keypad 114.

  When the back side case 110 and the front side case 120 are closed, the case open / close detection unit 224 detects this and instructs the application control unit 230 to activate the call control unit 232. And execute that function. Further, the display of the image moves to the display area 125 of the touch panel 121, and the inner display unit 122 is invalidated.

  The call control unit 232 monitors incoming calls when the application control unit 230 activates the mail control unit 234 or the game control unit 236. When there is an incoming call, the call control unit 232 causes the display area 125 or the inner display unit 122 of the touch panel 121 effective at that time to be overwritten and displayed.

  FIG. 8 is a perspective view showing the state of the back surface of the game mobile phone 101 in the state shown in FIG. 5 or FIG. As shown in the figure, a touch panel 121 is arranged on the front surface of the front case 120 corresponding to the back surface of the inner display section 122, as in the game mobile phone 100 shown in FIGS.

  As already described, the touch panel 121 can change its display image and function. Further, even when the front side case 120 and the back side case 110 are opened and the inner operation unit is operated, the finger reaches the touch panel 121 on the outer surface of the front side case 120. Therefore, when the inner operation unit is used, the operability of the inner operation unit can be improved by assigning operation regions 123 to both ends in the longitudinal direction of the touch panel 121.

  In the state shown in FIG. 8, operation areas for horizontal scrolling indicated by arrow H in the drawing and vertical scrolling indicated by arrow V in the drawing are arranged near both ends in the longitudinal direction of touch panel 121. Accordingly, the horizontal scroll operation and the vertical scroll operation can be performed by tracing these operation areas on the touch panel 121 with the fingers 252 and 254.

  That is, by horizontally tracing the surface of the touch panel 121 with the finger 252 of the right hand, the image displayed on the inner display unit 122 can be scrolled horizontally. Further, by vertically tracing the surface of the touch panel 121 with the finger 254 of the left hand, the image displayed on the inner display unit 122 can be scrolled vertically. Thereby, the inner side operation part formed in the inner surface of the back side housing | casing 110 can be specialized for character input, and operativity can be improved further.

  In addition, since the touch panel 121 located on the back surface with respect to the inner display unit 122 is not visible to the user, the touch panel 121 has no display image. On the other hand, the function of the touch panel 121 may be displayed on the inner display unit 122 instead. In the example illustrated in FIG. 6, the operation content of the touch panel 121 is displayed as an image 126 in the upper right corner of the inner display unit 122.

  Further, from the viewpoint of operating simultaneously with the inner operation unit such as the cross key 112, the numeric keypad 114, and the soft key 116, the touch panel 121 may be mounted on the outer surface of the back side casing 110 instead of the front side casing 120. Furthermore, by forming at least a part of the inner display unit 122 and the inner operation unit with a touch panel, further various operability can be obtained.

  In the embodiment shown in FIGS. 5 and 6, the numeric keypad 114 moves with respect to the back housing 110, but instead, the soft key 116 may move with respect to the back housing 110. In FIG. 6, when the numeric keypad 114 is moved to the right side, the display unit, the key, and the like may be arranged so that the liquid crystal display unit, other keys, and the like appear in the depressed portion 115.

  The game mobile phones 100 and 101 described above have operability and portability as a straight type mobile phone when the casing is closed. In addition, when the housing is opened, it has a wide internal display section and has good operability for games, character input, and the like. Furthermore, when the housing is opened, it has substantially the same arrangement and operability as the game machine.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
