  Next, a communication device according to an embodiment of the present invention is applied to a mobile phone device and will be described with reference to the drawings.

  FIG. 1 is a front perspective view of a mobile phone device as a communication device of the present invention.

  As shown in FIG. 1, the first housing 110 and the second housing 120 are rotated so as to be variable between a use state in which the first housing 110 and the second housing 120 are deployed in the illustrated state via the hinge mechanism unit 300 and a folded standby state. Connected movably.

  The first casing 110 and the second casing 120 are arranged on the side facing each other when folded in the standby state, for example, on the first casing 110 side, the main display unit 15 made of a liquid crystal display device. However, an input unit (operation unit) 17 in which a plurality of buttons and the like are arranged is provided on the second housing 120 side.

  The main display unit 15 makes a call destination telephone number input from the input unit 17 when making a call, information on the calling side at the time of incoming call (for example, a caller telephone number), a current time, and will be described later. The current position information and the like using the GPS and the Internet line are switched or displayed simultaneously according to the state.

  Note that the display state of the main display unit 15 is not the gist of the present invention except for the display related to the current position information using GPS and the Internet line, which will be described later, and the display state is not limited to the above. Accordingly, for example, a display function or the like arbitrarily set by the user (owner) such as displaying the main display unit 15 in a standby state (so-called standby screen) as a calendar display or an image display is appropriate. Can be adopted. The type of whether the display is monochrome or color is not particularly limited.

  The input unit 17 includes various keys (buttons) such as numeric keys from 0 to 9, a call key, a cut-off key, a function key, a scroll type or joystick type selection key, and the like.

  The input unit 17 inputs a telephone number, makes a call operation by a telephone book call operation registered in advance by the owner, a telephone book registration operation, a current position information acquisition operation using GPS and an Internet line, which will be described later, and destination guidance Although used when performing various operations such as operations, operations other than operations related to current position information (current position information acquisition operation / destination guidance operation, etc.) using the GPS and the Internet line described later are included in the gist of the present invention. The operation is not limited to the above. Therefore, for example, an operation performed by the user (owner) depending on the function attached to the mobile phone device, such as a mail operation using the Internet line, is appropriately performed. Also, the arrangement, type, and function of keys at that time are not particularly limited.

  FIG. 2 is a rear perspective view of the mobile phone device as the communication device of the present invention.

  In the first housing 110, for example, a sub display unit 16 made of a liquid crystal display device is arranged. The sub-display unit 16 can appropriately switch and display calling side information (for example, calling party telephone number) at the time of incoming call, current time, current position information using a GPS and an Internet line, which will be described later, and the like. It is. That is, the mobile phone device is turned between the use state and the standby state, and the main display unit 15 cannot be used in the standby state, so that the sub display unit 16 can be used as an auxiliary. It has become.

  The second housing 120 is equipped with an extendable antenna 2 and a CCD camera type imaging unit 18. In addition, a GPS antenna 22 (see FIG. 3) for receiving GPS data from a GPS satellite by a GPS receiving unit (receiving unit) 21 is mounted inside the antenna 2 (or inside the casings 110 and 120). However, in order to increase the reception sensitivity, the GPS antenna 22 may be mounted so as to be exposed to the outside.

  FIG. 3 is a block circuit diagram of a mobile phone device as a communication device of the present invention.

  The telephone communication unit 1 transmits a signal from a baseband unit 3 to be described later to a base station (not shown) via an antenna 2 and receives radio waves from the base station via the antenna 2.

  The baseband unit 3 adopts a CDMA system in this embodiment, and includes a CDMA processing circuit 31 and an audio codec 32.

  The CDMA processing circuit 31 performs code division multiple access (CDMA connection), scramble connection, error control, and timing detection.

  The audio codec 32 compresses (encodes) / decompresses (decodes) audio, A / D converts, and changes the received sound volume and the sensitivity of the microphone 6 by an internal amplifier circuit (not shown).

  The speaker 4 used at the time of transmission / reception converts the electric signal of the baseband unit 3 amplified by the amplifier circuit 5 into sound. The amplifier circuit 7 amplifies the output of the microphone 6 and outputs it to the baseband unit 3.

  The speaker (notification unit) 8 converts the electric signal of the baseband unit 3 amplified by the amplifier circuit 9 into sound. In addition, the speaker 8 outputs an incoming call notification sound and voice guidance regarding current position information using a GPS and an Internet line, which will be described later.

  The switching circuit 10 turns on / off the connection between the three amplifying circuits 5, 7, 9 and the baseband unit 3 under the control of a control unit (calculation unit) 11 described later. These amplifier circuits 5, 7, and 9 have fixed gains. Therefore, the voice codec 32 changes the received sound volume and the sensitivity of the microphone 6.

  The control part (calculation part) 11 controls each part based on the system program stored in the 1st storage part 12 which consists of ROM, for example.

  The second storage unit 13 is composed of, for example, a flash memory.

  This flag is a flag indicating whether or not position information is not displayed on the main display unit 15 (or the sub display unit 16). For example, when the flag is off, the position information is displayed on the main display unit 15, and when the flag is on, the position information is not displayed on the main display unit 15.

  The third storage unit 14 includes, for example, a RAM, and indicates a course to be followed next, such as a voice message for notifying the user (user) of position information, for example, “turn the next corner”. And a voice message indicating the current position such as “current location is XX city ×× 1 chome”. In addition, it stores a voice message when a surrounding specific facility is specified, such as “Please turn right 180m away from the bank XX bank. After that, 100m, your destination.” . Note that this message can also be obtained from Internet information.

  The image processing unit 19 performs compression processing or the like on the image information captured by the imaging unit 18 and outputs it to the control unit 11.

  The open / close detection unit 20 detects the open / closed state of the first housing 110 and the second housing 120. Specifically, the switch is turned on when the first housing 110 and the second housing 120 are folded from the standby state to start use (opened electrically). Then, it is determined that the first casing 110 and the second casing 120 are in use. Based on the determination result, for example, the control unit 11 turns on the backlight of the liquid crystal display screen of the main display unit 15 or turns on an illumination lamp (not shown) provided on the back surface of the input unit 17. To do. The various illumination functions are turned off when there is no key operation from the input unit 17 for a predetermined time.

  Next, a communication method by the communication apparatus according to the present embodiment will be described based on a flowchart shown in FIG.

  In step 1, the GPS receiving unit 21 acquires current position information necessary for specifying the current position by the GPS antenna 22, and the process proceeds to step 2.

  In Step 2, the current position is calculated by the control unit 11 based on the current position information received in Step 1, and the process proceeds to Step 3.

  In step 3, map data around the current position is acquired through the Internet line based on the calculated current position, and the process proceeds to step 4.

  In step 4, based on the acquired map data and the current position information, the control unit 11 recognizes an icon indicating the current position (for example, the traveling direction is recognized) on the main display unit 15 or the sub display unit 16 (which may be both). ) And the surrounding map are displayed in a map-matched state, and the process proceeds to step 5.

  In the case of a navigation-only device other than the mobile phone device as in the present embodiment, the map data around the current position is acquired by reading the information storage medium storing the map data with the reading device.

  In step 5, it is determined whether or not a destination designation operation has been performed by the input unit 17. If a destination designation operation has been performed, the process proceeds to step 6 where the destination designation operation is performed. If not, loop to step 1.

  In addition, if the user moves every time it loops to this step 1, the current position and the surrounding map will be updated. In addition, the map match for the mere current position where navigation to the destination is not performed is not displayed on the main display unit 15 or the sub display unit 16 in the case of normal telephone use or Internet use.

  In step 6, in accordance with the designation of the destination, the destination information is stored in the area A of the second storage unit 13 in the destination information (address data, etc.), and the unique facility information around the destination is obtained via the Internet line. As shown in FIG. 5A, a list of surrounding facilities is displayed on the main display unit 15, and the process proceeds to step 7.

  In step 7, an arbitrary unique facility is designated from the peripheral facility list displayed on the main display unit 15 ("B bank XX branch" is designated for the character list on the drawing), and the designated unique facility is designated. Information (for example, address data) is stored in the area B of the second storage unit 13 and the process proceeds to step 8.

  Note that this fixed facility list may be specified not from character data but from a map display around the destination in consideration of the shortest travel route.

  In step 8, the map match display state displayed on the main display unit 15 in step 5 is restored, navigation is started, and the process proceeds to step 9.

  In this navigation state, the same routine as that in steps 1 to 4 is performed in parallel.

  In step 9, it is determined based on the current position information whether or not the user has moved to an area where a voice message is required (for example, a right / left turn notification area or a destination area notification area), and an area where a voice message is required. If the user has moved up to step S10, the process proceeds to step 10. If the user is moving outside the area where the voice message is necessary, the navigation is continued while monitoring step 9.

  In step 10, for example, as shown in FIG. 5 (B), based on the determination that the user has moved to the destination area notification area, for example, turn right 180m ahead from “XX Bank ×× Branch”. Please go ahead, 100m, your destination. " Note that when the user determines that he / she is in a necessary area, the user himself / herself operates the input unit 17 so that a voice message may be notified.

  Therefore, the user can visually recognize the remaining distance from the actual landscape by viewing Bank B from the actual landscape.

  That is, the user can recognize the approximate distance measured from the current position to Bank B by experience, so by checking the signal ahead, which side is 180m ahead to turn right, etc. Can be recognized.

  In addition, by visual inspection of the surroundings, if the specified specific facility is not found, it is possible to easily recognize that there is an error in the voice guidance or the map match because the current position is not accurately obtained. .

  At this time, if additional information regarding the unique facility as the current position information is additionally input from the input unit 17, the unique facility can be arbitrarily designated (changed) from the actual scenery in the movement route, and changes with time. In addition to being able to easily deal with specific facilities, correct the displacement of the current position due to the received radio wave status of GPS satellites, correct the subsequent movement route if the movement route is wrong, etc. The remaining distance required for route guidance can be recognized using the unique facility as the current position.

  In the above-described embodiment, an example in which a voice message is notified from the speaker 8 has been described. However, a text message may be displayed on the main display unit 15 or the sub display unit 16 together with (or alone).
