  A control circuit 36 is connected to each of the communication unit 12, the baseband unit 14, and the switching circuit 22. Switching by the switching circuit 22 described above is performed under the control of the control circuit 36. The control circuit 36 controls the audio codec 20 of the baseband unit 14, and the audio codec 20 changes the volume of the first speaker 26 and the second speaker 34 and the sensitivity of the microphone 30.

  The control circuit 36 includes a microprocessor as a main component, and is connected to a ROM 38 and a RAM 40, and controls each unit based on a system program stored in the ROM 38. Data that needs to be temporarily stored during execution of the program is stored in the RAM 40.

  The RAM 40 stores not only the address book and received mail but also downloaded content data. Here, the content data includes image data, character data, music data, and the like, and the content data is downloaded from the content server 11 that provides the content data via the communication unit 12 according to an instruction from the control circuit 36 and stored in the RAM 40. Remembered.

  The downloaded content data is added to the free space according to the free capacity of the RAM 40 or overwritten on the already registered content.

  An input unit 44 is connected to the control circuit 36. The input unit 44 includes a numeric keypad 48 for inputting a telephone number, a call key 50 for operating a start of a call, a cut key 52 for operating a call end, an OK key 54, and a clear key 56. Have.

Further, contact detection sensors for detecting that the user has touched are provided on the surfaces of all the numeric keys 48 and the casing surface around the numeric keys 48. This contact detection sensor is conventionally known, and for example, a transparent electrode or the like is used. The contact detection sensor disposed on the casing and key top of the mobile phone is electrically connected to the control circuit 36. Therefore, a signal indicating that the user has touched the contact detection sensor is input to the control circuit 36.

  In this embodiment, the contact detection sensor is disposed on the front surface of the housing, but may be disposed inside the housing such as the back surface side of the housing or the back surface side of the key 48. For example, if it is a capacitance detection type contact detection sensor, it can be arranged inside the housing. In addition, when the contact detection sensor is disposed on the entire back surface side of the key 48, wiring is greatly simplified as compared with the configuration in which the contact detection sensor is disposed on the key top.

  In addition, a display 42 and an illumination unit 46 are connected to the control circuit 36. The display 42 is composed of a liquid crystal panel, for example, and displays a standby screen, an incoming message, a telephone number, mail and other visual information under the control of the control circuit 36. Moreover, the illumination part 46 consists of LED elements, for example.

  In addition, an open / close detection unit 58 is connected to the control circuit 36. The opening / closing detection unit 58 supplies an open state detection signal to the control circuit 36 when detecting an operation of opening the display-side casing 102 of the mobile phone 10 by the user. The control circuit 36 reads the content data stored in the RAM 40 based on the open state detection signal from the open / close detection unit 58 and outputs the content data from the display 42 or the second speaker 34.

  The setting for outputting / not outputting the content data from the display 42 or the second speaker in accordance with the open state of the display-side housing 102 is performed by the user on the setting screen displayed on the display 42 in various ways on the input unit 44. This is done by operating the keys. Further, selection setting of content data to be output from the display 42 or the second speaker 34 is also performed by the user operating various keys of the input unit 44 on the setting screen displayed on the display 42. Specifically, for example, an arbitrary word is read from the electronic dictionary data stored in the RAM 40 and displayed on the display 42 each time the display-side housing 102 is expanded.

  In addition, the control circuit 36 counts the number of open states of the display-side housing 102 based on the open state detection signal from the open / close detection unit 58 and downloads content data from the content server 11 based on the count value. Specifically, for example, every time the display side housing 102 is expanded 1000 times, an additional word (character data) used as electronic dictionary data is newly downloaded from the content server 11 in units of about 200 words. . Note that the setting of whether or not to download the content data may also be performed by the user operating various keys of the input unit 44 on the setting screen displayed on the display 42.

  The control circuit 36 reads out the content data stored in the RAM 40 based on the open state detection signal from the open / close detection unit 58 and outputs it from the display 42 or the second speaker 34, but is stored in the RAM 40. The content data may be downloaded from the content server 11 based on the proportion of the content data read out for output from the display 42 or the second speaker 34 out of the total content data.

  Specifically, for example, when 1000 words are stored in advance in the RAM 40 as electronic dictionary data, 900 words are read out by continuing the expansion operation of the display-side housing 102. When displayed on the display 42, an additional word (character data) used as electronic dictionary data is newly downloaded from the content server 11 in units of about 200 words.

  Further, the control circuit 36 updates the content data already stored in the RAM 40 with the content data newly downloaded from the content server 11. Specifically, for example, if the storable capacity of the electronic dictionary data allocated in the RAM 40 is 1000 words, the number of words already stored in the RAM 40 is 800 words less than 1000 words. When 200 words are newly downloaded as words, they are stored in the empty area.

  On the other hand, in the case where 1000 words are already stored in the RAM 40, when 200 words are newly downloaded as additional words, the already displayed words are selected from the stored 1000 words, or The 200 words are overwritten for words that have been downloaded at an old time or for words that are randomly selected.

  Here, if arbitrary content data is automatically overwritten and deleted, there is a problem that the content data cannot be viewed again later. For this reason, an update prohibition flag is provided for the content data to be retained so that it remains in the RAM 40 without being overwritten even if an update process is performed by downloading new content data, and the display side housing 102 is expanded. In the content data output at the time, the control circuit 36 causes the control circuit 36 to press the predetermined key provided in the input unit 44, for example, the OK key 54. Set the update prohibition flag to ON.

  By controlling in this way, when the content data already stored in the RAM 40 is updated with the content data newly downloaded from the content server 11, the control circuit 36 selects the content data for which the update prohibition flag is ON. It can be excluded from the update target.

  Next, the download operation of the mobile phone according to the present invention will be described.

  FIG. 4 is a flowchart illustrating the operation of the mobile phone according to the present embodiment.

  Note that the operation shown in FIG. 4 is realized by executing a control program stored in the ROM 40 connected to the control circuit 36.

  In the flowchart of FIG. 4, in step S400, the control circuit 36 controls the open / close detection unit 58, whereby the open / close detection unit 58 detects the open state of the display-side casing 102, and the control circuit 36 is based on the detection result. In step S401, if the display side housing 102 is opened, the process proceeds to step S401. If the display side housing 102 is not opened, the process in step S400 is performed. Return to.

  In step S <b> 401, the control circuit 36 updates the counter value of the open state count, reads an arbitrary word from the electronic dictionary data stored in the RAM 40, and displays it on the display 42.

  In step S402, the control circuit 36 determines whether or not the counter value has exceeded a predetermined number of times, for example, 1000 times, and proceeds to step S403 if it is greater than or equal to the predetermined number of times, whereas if it is less than the predetermined number of times, step S400. Return to the process.

  In step S403, the control circuit 36 determines whether or not to newly download an additional word (character data) used as electronic dictionary data from the content server 11, and proceeds to step S404 when downloading. On the other hand, if not downloaded, the process ends.

  In step S404, the control circuit 36 newly downloads an additional word (character data) to be used as electronic dictionary data from the content server 11. In step S405, the downloaded additional word is stored in the RAM 40 and processed. Exit.

  As described above, according to the portable terminal device of the present invention, when the usable state detecting unit that detects the usable state of the device detects that the portable terminal device is usable, the content output unit The content stored in the content storage means for storing a plurality of contents to be output to the content is read out and output to the content output means, and the content existing on the server is downloaded by connecting to the server at every predetermined event Thus, the content is stored in the content storage means, so that the mobile terminal device can always keep the content stored in the content storage means in a new state. Therefore, it is possible to provide meaningful content that does not get tired for the user. Further, since the user can avoid complicated operations necessary for downloading the content, convenience for the user is improved.
