To do.

  FIG. 3 shows a configuration block of the mobile phone shown in FIGS.

  A radio signal transmitted from a base station (not shown) is received by an antenna 31 and then input to a receiving circuit (RX) 33 via an antenna duplexer (DUP) 32. The receiving circuit 33 mixes the received radio signal with the local oscillation signal output from the frequency synthesizer (SYN) 34 and converts the frequency into an intermediate frequency signal (down-conversion). Then, the down-converted intermediate frequency signal is orthogonally demodulated and a received baseband signal is output. Note that the frequency of the local oscillation signal generated from the frequency synthesizer 34 is indicated by a control signal SYC output from the control unit 41.

  The received baseband signal is input to the CDMA signal processing unit 36. The CDMA signal processing unit 36 includes a RAKE receiver. The RAKE receiver despreads each of a plurality of paths included in the received baseband signal using a spreading code, and synthesizes the signals of the paths subjected to the despread processing after adjusting the phase. As a result, received packet data in a predetermined transmission format is obtained. This received packet data is input to the compander 37.

  The compander 37 decodes voice data contained in the received packet data output from the CDMA signal processing unit 36 by a speech codec during a call, and outputs a digital audio signal obtained by this decoding to the PCM codec 38. To do. The PCM codec 38 PCM-decodes this digital audio signal and outputs an analog speech signal. The analog speech signal is amplified by the reception amplifier 39 and then output from the speaker 18.

  Further, the compander 37 passes the e-mail data or the content data included in the received packet data to the control unit 41 when receiving the e-mail or downloading the content. The control unit 41 stores e-mail data or content data passed from the compander 37 in the storage 42 or the memory card 43.

  When an e-mail display request is input via the operation key 14 or the side key 16, the control unit 41 reads out the corresponding e-mail data from the storage 42 or the memory card 43 and displays it on the main display 17.

  In addition, when a content reproduction request is input via the operation key 14 or the side key 16, the control unit 41 reads the corresponding content data from the storage 42 or the memory card 43.

  If the content data is audio content, the control unit 41 outputs the audio data to the compander 37. The audio data is decoded by the compander 37, further converted into an analog signal by the PCM codec 38, amplified by the reception amplifier 39 and output from the speaker 18.

  On the other hand, when the content data is video content, the control unit 41 decodes the video data with an internal video codec and displays the decoded video data on the main display 17.

  On the other hand, during a call, the speaker's voice signal input to the microphone 15 is amplified to an appropriate level by the transmission amplifier 40 and then subjected to PCM encoding processing by the PCM codec 38 to become a digital audio signal. Input to the compander 37. The video signal output from the CCD camera 20 is digitized by the control unit 41 and input to the compander 37.

  The compander 37 detects the energy amount of the input voice from the digital audio signal output from the PCM codec 38, and determines the transmission data rate based on the detection result. Then, the digital audio signal is encoded into a signal having a format corresponding to the transmission data rate, thereby generating audio data. The digital video signal output from the control unit 41 is encoded to generate video data. Then, these audio data and video data are packetized by the demultiplexing unit according to a predetermined transmission format, and this transmission packet data is output to the CDMA signal processing unit 36. Further, when text data such as mail is output from the control unit 41, the text data is multiplexed with the transmission packet data.

  Note that the video data generated by the compander 37 is displayed on the main display 17 under the control of the control unit 41.

  The CDMA signal processing unit 36 performs spread spectrum processing on the transmission packet data output from the compander 37 using the spreading code assigned to the transmission channel. Then, the output signal is output to the transmission circuit (TX) 35. The transmission circuit 35 modulates the spectrum spread signal using a digital modulation method such as a QPSK (Quadrature Phase Shift Keying) method or a QAM (Quadrature Amplitude Modulation) method. Then, the transmission signal generated by this modulation is combined with a local oscillation signal generated from the frequency synthesizer 34 and frequency-converted into a radio signal. Then, the radio signal is amplified at a high frequency so that the transmission power level instructed by the control unit 41 is obtained. The amplified radio signal is supplied to the antenna 31 via the antenna duplexer 32 and transmitted from the antenna 31 to the base station.

  The sub-display 21 displays information indicating the operation mode of the mobile phone 10, incoming call notification information, and information indicating the remaining amount or charge state of the battery 45. The power supply circuit 46 generates a predetermined operating power supply voltage Vcc based on the output of the battery 45 and supplies it to each circuit unit. The battery 45 is charged by a charging circuit (not shown).

  The mobile phone 10 can set various settings related to operations by the control unit 41 via the operation keys 14 and the main display 17. The setting contents are stored in the storage 42, read by the control unit 41 as necessary, and used for operation control.

  As described above, the second housing 13 having the main display 17 can be biaxially rotated with respect to the first housing 12 by the hinge portion 11. At the time of carrying, as shown in FIG. 2, the first housing 12 and the second housing 13 are folded with the main display 17 facing inward. During a call, as shown in FIG. 1, the second housing 13 is placed on the X axis with respect to the first housing 12 so that the first housing 12 and the second housing 13 are almost straight. It is rotated 180 degrees around and opened. Furthermore, the first casing 12 and the second casing 13 may be folded with the main display 17 facing outward for viewing the content (reproduction of content such as image data and music data). .

  In the present specification, a state in which the first casing 12 and the second casing 13 are folded with the main display 17 facing inward is a “closed state”, and the first casing 12 and the second casing 13 are folded. The state in which the body 13 is stretched almost straight is “open state”, and the state in which the first housing 12 and the second housing 13 are folded with the main display 17 facing outward is “turnover” It shall be called “state”. A series of operations for transforming the mobile phone 10 from the “open state” to the “turnover state” is called “turnover operation”, and the operation for releasing the “turnover state” is called “turnover release operation”. Shall be called.

  FIG. 4 shows a state of deformation of the mobile phone in the turnover operation. In the turnover operation, the second casing 13 is rotated 180 degrees around the Y axis with respect to the first casing 12 from the opened state, and then the second casing is rotated with respect to the first casing 12. 13 is rotated by 180 degrees around the X axis.

  FIG. 5 shows the transition of the display screen during an operation of viewing content in a turnover state in a conventional biaxial rotating mobile phone. 5A shows the transition of the display screen when the turnover operation is performed after the reproduction start operation, and FIG. 5B shows the transition of the display screen when the reproduction start operation is performed after the turnover operation. Show.

  In the technique of performing the turnover operation after the reproduction start operation, the user carries the turnover operation after the reproduction start operation and changes the mobile phone in a direction suitable for viewing. Further, as can be seen from FIG. 5A, the reproduction of the content is started when it is in an open state. For this reason, the user may miss the top part of the content.

  In the method of starting the playback after the turnover operation, the user moves the mobile phone in a direction suitable for viewing while performing the turnover operation, and then uses the auxiliary key such as the side key to start the playback operation. Do. As can be seen from FIG. 5B, in this method, the reproduction of the content is surely started after the mobile phone is turned over. However, since auxiliary keys such as side keys are generally difficult to operate on the side or the like, the operation is troublesome for the user and is likely to be erroneously operated.

  FIG. 6 shows the transition of the display screen at the time of an operation for stopping the content being reproduced in the turnover state in the conventional two-axis rotation type mobile phone. 6A shows the transition of the display screen when the playback stop operation is performed after the turnover release operation, and FIG. 6B shows the display screen when the turnover release operation is performed after the playback stop operation. It shows the transition.

  In the method of performing the playback stop operation after the turnover canceling operation, the user performs the playback stop operation after performing the turnover canceling operation to be in the open state. Further, as can be seen from FIG. 6A, the reproduction of the content is continued until the reproduction stop operation is performed even after being transformed into the open state. For this reason, reproduction cannot be stopped immediately. In addition, in the case of having a suspend / resume function for storing the stop position, the start position of the next reproduction is ahead of the position where the user has already viewed.

  In the technique of performing a turnover release operation after performing a playback stop operation, the user performs a playback stop operation using an auxiliary key such as a side key and then performs a turnover release operation. As can be seen from FIG. 6B, in this method, the reproduction of the content is surely stopped before the mobile phone is released from the turnover state. However, since auxiliary keys such as side keys are generally difficult to operate on the side or the like, the operation is troublesome for the user and is likely to be erroneously operated. For this reason, it is difficult to stop the reproduction at a desired location.

  On the other hand, the mobile phone 10 according to the present embodiment has a function of automatically starting the content reproduction upon detecting the turnover state and automatically stopping the content reproduction upon detecting the turnover state cancellation. Have. The turnover state detection and turnover state release detection are performed by the magnetic sensors 19a, 19b, 19c, and 19d.

  This automatic playback / stop function can be set to valid / invalid, and the valid / invalid is set by the control unit 41 via the operation keys 14 and the main display 17 and stored in the storage 42 as in other settings. The

  FIG. 7 shows the transition of the display screen during the automatic playback / stop operation by the turnover operation in the mobile phone of this embodiment. FIG. 7A shows the transition of the display screen in the automatic playback / stop operation from the data list display, and FIG. 7B shows the transition of the display screen in the automatic playback / stop operation from the folder list display. Yes.

Do. When it is detected that the turnover state has been reached, reproduction of the corresponding data is started. Further, when it is detected that the turnover state is released during reproduction, the reproduction of the corresponding data is stopped.

  In the automatic playback / stop operation from the folder list display, as shown in FIG. 7B, first, in the opened state, the user selects a desired video folder from the folder list display, and then performs a turnover operation. To do. When the turnover state is detected, continuous playback of data contained in the corresponding folder is started. Further, when it is detected that the turnover state is released during reproduction, the continuous reproduction of data included in the folder is stopped.

  That is, the mobile phone 10 starts playback as soon as it enters the turnover state, and stops playback as soon as it is no longer in the turnover state. Thus, since the reproduction is started by the detection of the turnover state, the user does not miss the head portion of the moving image data. In addition, since playback is stopped in response to detection of turnover state cancellation, playback is immediately stopped. Furthermore, since the user's operation for determining the start and stop timing of the reproduction is an operation for opening and closing the second housing 13 with respect to the first housing 12, there is almost no fear that the user will make an erroneous operation.

  FIG. 8 shows the transition of the display screen during the setting operation for enabling / disabling the automatic content playback function in the mobile phone of this embodiment. FIG. 8A shows the transition of the display screen when the automatic content playback function is enabled, and FIG. 8B shows the transition of the display screen when the content automatic playback function is disabled. Show.

  The content automatic playback function can be enabled / disabled individually for each data type. As shown in FIG. 8, a list of data types (content types) is displayed on the setting screen. Valid / invalid of the automatic content reproduction function is displayed for each. By selecting the data type and performing a setting switching operation, the content automatic playback function is switched between valid / invalid.

  The mobile phone 10 has a suspend / resume function for resuming content playback from the previous stop position. The suspend / resume function can be set to valid / invalid, and the valid / invalid is also set by the control unit 41 via the operation key 14 and the main display 17 and stored in the storage 42 as in other settings. . When the suspend / resume function is valid, the stop position is stored in the storage 42 when the reproduction of the content is stopped. Then, in FIG. 8, the automatic content playback function may be controlled to be enabled / disabled in conjunction with the enable / disable setting, or another item may be provided in FIG. 8 to suspend. / Enable / disable of resume function may be set.

  Hereinafter, an operation of viewing content such as image data and music data in a turnover state will be described with reference to FIG.
