It is explanatory drawing of the 4th modification.

  FIG. 1 is a perspective view showing an appearance of a mobile phone 1 according to an embodiment of the present invention.

The mobile phone 1 is configured as a foldable type.
The mobile phone 1 includes a first housing 2 and a second housing 3.

The first housing front case 4 and the first housing rear case 5 are fixed to each other with screws or the like, and various electronic members are formed in a space formed between the first housing front case 4 and the first housing rear case 5. A housing space for housing the container is configured.
The second casing front case 6 and the second casing rear case 7 are also fixed to each other by screws or the like, and various electronic members are formed in a space formed between the second casing front case 6 and the second casing rear case 7. A housing space for housing the container is configured.
The first casing front case 4, the first casing rear case 5, the second casing front case 6, and the second casing rear case 7 are made of resin, for example.

In addition, when the first housing 2 is up and the second housing 3 is down as shown in FIG.
The direction toward the right side 11 is referred to as the right side direction (the right direction in FIG. 1), and the direction toward the left side 12 is referred to as the left side direction (the left direction in FIG. 1). .

As shown in FIG. 1, the display unit 8 is arranged in the first housing front case 4.
This display unit 8 is for displaying various information such as the state of the mobile phone 1, the user's operation content, the destination telephone number, the content of the e-mail, the game screen, and the like.
The display unit 8 includes an LCD (liquid crystal display), an OLED (Organic light-emitting diode: organic EL), and the like.

  Further, as shown in FIG. 1, the input unit 10 is disposed in the surface direction of the second housing front case 6. When the user operates the input unit 10, an instruction, a character, or the like is input to the mobile phone 1.

Although not shown in FIG. 1, various sensors constituting the detection unit 60 are arranged inside the first housing 2 or the second housing 3.

For example, the water detection sensor 62 is preferably arranged on the surface side of the first housing 2 or the second housing 3 that should first come into contact with water when it gets wet. For example, it is preferable to arrange in the vicinity of the CPU that is most likely to become hot.

In general, the cellular phone 1 as shown in FIG. 1 often stores information important to the user in a storage unit 70 (not shown). For example, image information such as still images / moving images taken by an imaging unit 55 (not shown), transmission / reception contents of electronic mail, recorded voice information, address book information, schedule information, and the like.
These important information may be backed up frequently, but users who perform such actions are rare.
Furthermore, even if a backup is taken, the information after the backup cannot be saved.
Therefore, the present embodiment is intended to prevent such important information from being lost.
Such loss of important information is often caused by the cellular phone 1 being damaged due to submergence, burning, temperature rise, or the like.
Therefore, in the present embodiment, the detection unit 60 detects a case where such damage may occur, and transfers it to the storage unit 70 having higher storability and stores it (transfer storage).
This makes it possible to protect important information as much as possible.
A specific method for this will be described below.

  FIG. 2 is a block diagram showing a signal processing system of the mobile phone 1 of FIG.

  As shown in FIG. 2, the mobile phone 1 includes a control unit 57, which is the center of control and processing, a communication unit 51, an operation unit 52, a voice input / output unit 53, a display unit 8, and an imaging unit 55. Each of the storage units 70 is commonly connected to a system bus 58 including a plurality of lines for address, data, and control.

  The communication unit 51 captures a wireless communication system, performs wireless communication with the base station 100 connected to the communication network, and transmits and receives various data. The various types of data include file data downloaded from a download site on the web, voice data during a voice call, mail data during mail transmission / reception, web page data during web browsing, and the like.

The operation unit 52 receives user instructions input from the input unit 10 and other parts.
In the input unit 10, for example, keys to which various functions are assigned such as a power key, a call key, a numeric key, a character key, a direction key, a determination key, a call key, and a function key are arranged.
When these keys are operated by the user, a signal corresponding to the operation content is generated and output to the control unit 57 as a user instruction.

The audio input / output unit 53 performs input / output processing of an audio signal output from a speaker or an audio signal input from a microphone.
That is, the voice input / output unit 53 amplifies the voice input from the microphone, performs analog / digital conversion, further performs signal processing such as encoding, converts it into digital voice data, and outputs it to the control unit 57. .
The audio input / output unit 53 performs signal processing such as decoding, digital / analog conversion, and amplification on the audio data supplied from the control unit 57, converts the audio data into an analog audio signal, and outputs the analog audio signal to the speaker.
The voice detected by the microphone of the voice input / output unit 53 is stored in the storage unit 70 described later.

The display unit 8 is configured using, for example, an LCD or an OLED, and displays an image corresponding to the video signal supplied from the control unit 57.
The display unit 8 includes, for example, a telephone number of a transmission destination at the time of wireless transmission by the communication unit 51, a telephone number of a transmission source at the time of reception, contents of received mail and transmitted mail, date, time, remaining battery level, success / failure of transmission, standby Display the screen.

The imaging unit 55 is a camera configured by a photoelectric conversion element such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor) image sensor and a control circuit thereof.
In this imaging unit 55, still image or moving image information captured is stored in the storage unit 70.

The storage unit 70 stores various data used for various processes of the mobile phone 1.
The storage unit 70 is, for example, a computer program executed by the control unit 57, a telephone number of a communication partner, an audio file for reproducing a ringtone or an alarm sound, an image file for a standby screen, various setting data, a program Temporary data used in the process is stored.
In the present embodiment, audio information detected by the audio input / output unit 53 is stored in the storage unit 70.
In addition, the storage unit 70 stores information on still images and moving images captured by the imaging unit 55.
Further, the storage unit 70 also stores an address book for managing personal information such as an e-mail address and a telephone number, and contents of the e-mail.
In addition, the storage unit 70 also stores schedule information input by the input unit 10 or the like.
Information other than those described above is also stored in the storage unit 70.

The storage unit 70 includes a RAM 71, a ROM 72, a memory card 73, and the like.
Which of the RAM 71, the ROM 72, and the memory card 73 constituting the storage unit 70 is used to store information is appropriately selected according to the information.
The RAM 71 is composed of, for example, a DRAM, an SRAM, or the like.
The memory card 73 is a detachable packaged memory.
The RAM 71, the ROM 72, and the memory card 73 described above are merely examples of the storage unit 70, and other storage devices can be used as the storage unit 70.
It is also possible to newly develop a more robust and highly storable storage device for transferring and storing information when the cellular phone 1 is damaged.

The RAM 71, the ROM 72, and the memory card 73 have different storability (safety) based on their structures.
That is, since the memory card 73 can be carried independently, the memory card 73 can hold the internal information without the supply of electricity.
Furthermore, the memory card 73 is held by a relatively sturdy housing so that it can be carried independently, and can hold information even if there is some water wet, temperature rise, or the like.
On the other hand, DRAM, which is an example of the RAM 71, loses information as soon as power supply is lost.

Therefore, when the mobile phone 1 is likely to be damaged, if the information can be saved in the memory card 73 having higher storability, the mobile phone 1 is damaged. In addition, it becomes possible to read the information stored in the transfer.
Therefore, in the present embodiment, when the detection unit 60 detects the external environment and satisfies a certain condition, important information is saved in the storage unit 70 (memory card 73) having the highest storability. .
This makes it possible to transfer and store information important to the user (which cannot be reproduced) in the storage unit 70 with higher storability (safety), so that the risk of losing this information can be reduced. It becomes possible.

The detection unit 60 detects the external environment of the mobile phone 1.
In the present embodiment, the temperature detection sensor 61, the water detection sensor 62, and the acceleration detection sensor 63 are used.
However, the present invention is not limited to the above-described sensors, and various sensors can be mounted as necessary.
When it is determined that the detection unit 60 including the temperature detection sensor 61, the water detection sensor 62, the acceleration detection sensor 63, and the like satisfies a certain condition, the control unit 57 is notified accordingly.

The control unit 57 comprehensively controls the overall operation of the mobile phone 1.
That is, in the control unit 57, various processes of the mobile phone 1 (voice calls performed via a circuit switching network, creation and transmission / reception of e-mails, browsing a download site on the Internet, etc.) The operation of each block described above (transmission / reception of signals in the communication unit 51, display of an image in the display unit 8, imaging processing in the imaging unit 55, etc.) is controlled so as to be executed in an appropriate procedure accordingly.
Furthermore, the control unit 57 includes a computer (microprocessor) that executes processing based on a program (operating system, application program, etc.) stored in the storage unit 70, and has been described above according to the procedure instructed in this program. Execute the process.
That is, the control unit 57 sequentially receives instruction codes from programs such as an operating system and application programs stored in the storage unit 70 and executes processing.

In the present embodiment, in particular, the control unit 57 performs the following operation.
When there is a change in the external environment notified from the detection unit 60, the control unit 57 uses the information stored in the storage unit 70 (for example, the RAM 71) having low storability in the storage unit 70 with high storability. It transfers to the memory | storage part 70 (for example, memory card 73), and memorize | stores (copy).

Note that the information that the control unit 57 copies from the storage unit 70 with low storability to the storage unit 70 with high storability need not be all, and it is preferable to copy from information with high importance.
It is also possible to set in advance to give priority to image information such as moving images and still images that are generally highly important.
It is more suitable if the importance can be set by the user.

  FIG. 3 is a flowchart for explaining processing in the present embodiment.

In step ST01, the detection unit 60 detects the external environment.
In addition to directly detecting the external environment, the external environment can also be detected indirectly by detecting the temperature around the CPU, for example.

In step ST02, it is determined whether the external environment detected by the detection unit 60 satisfies a certain condition.
For example, in the case of the acceleration sensor 63, the certain condition is a case where an acceleration having such an intensity that the cellular phone 1 is damaged is applied.
In the case of the smoke detection sensor 65, it is a case where it is determined that the smoke is so large that the mobile phone 1 is damaged.
If the predetermined condition is not satisfied, the process returns to step ST01.
On the other hand, if it is determined that certain conditions are satisfied, the process proceeds to step ST03.

In step ST <b> 03, the control unit 57 selects the storage unit 70 most appropriate for saving information from the storage unit 70.
For example, if the RAM 71, the ROM 72, and the memory card 73 are mounted, the memory card 73 is selected.
In addition, if there is a storage unit 70 with higher storability, it is preferable to save information in the storage unit 70.

  In step ST04, the data is transferred to the storage unit 70 selected in step ST03 and copied (saved).

  With the above configuration, when there is a possibility that the mobile phone 1 may be damaged, the information in the mobile phone 1 can be transferred and stored in the storage unit 70 with higher storability (safety). .

<First Modification>
A more preferable first modification will be described below.
FIG. 4 is an explanatory diagram of the first modification.

4 is different from FIG. 2 in that important information stored in the storage unit 70 by the communication unit 51 is stored in the external storage unit 74 existing outside the mobile phone 1.
That is, when the detection unit 60 detects a certain condition (state), the control unit 57 transfers and stores the information stored in the storage unit 70 in the external storage unit 74 through the communication unit 51.
The communication unit 51 communicates with the base station 100 and transmits an information signal to the base station 100.
The base station 100 that has received this information signal transfers and stores this information signal in the external storage unit 74 through the communication network 101.
The communication network 101 may be an Internet communication network, a telephone communication network, or another communication network 101.
The external storage unit 74 may be an external storage unit 74 managed by the user (for example, a storage device of the user's home personal computer), or the external storage unit 74 managed by a person who manages the mobile phone 1 or the like. There may be.
In addition, the external storage unit 74 may be a communication destination with which the mobile phone 1 last communicated (call).

  FIG. 5 is a flowchart for explaining processing in the first modification.

The process of FIG. 5 is basically the same as the process of FIG. 3, but the difference is that the process from step ST05 to step ST07 is performed.
Since the processing from step ST01 to step ST04 is the same, the description thereof is omitted.

  In step ST05, radio wave conditions such as radio wave intensity and error rate of the communication unit 51 are detected.

In step ST06, it is determined whether data (information) can be transmitted based on the radio wave condition detected in step ST05.
If it is determined that data can be communicated, the process proceeds to step ST07.
On the other hand, if it is determined that the data cannot be communicated, the process proceeds to step ST03.
That is, when the communication unit 51 cannot be used for storage, the storage (transfer storage) of information to the outside is stopped, and the most storable (safety) of the storage units 70 installed in the mobile phone 1. Save (transfer storage) in the high storage unit 70.

By configuring as described above, it is possible to transfer and store important information in the external storage unit 74 with higher safety.
As a result, information can be stored more reliably.

  In this embodiment, the storage in the external storage unit 74 using the communication unit 51 and the storage in the storage unit 70 having the highest storability among the internal storage units 70 are selective. It can also be done in parallel.

<Second Modification>
A more preferable second modification will be described below.
In the above embodiment and the first modification, when the detection unit 60 detects a certain state, the information is simply transferred and stored in the storage unit 70 having higher storability. It is more preferable to notify the user to that effect.
For this notification, it is effective to use the display unit 8, the indicator, the speaker of the voice input / output unit 53, and the like.
As a result, the user can remove or save the cause.

<Third Modification>
A more preferable third modification will be described below.
FIG. 6 is an explanatory diagram of a third modification.
In particular, this is a modification of the water detection sensor 62 that detects water (liquid).
The mobile phone 1 may have an infrared communication unit 25.
The first cover member 27 covers the infrared communication unit 25.
The first cover member 27 includes a first concave portion 29 that is formed on the surface of the housing and has a concave shape that can store a liquid.
The infrared communication unit 25 includes an infrared transmission unit 21 that can emit infrared rays and an infrared reception unit 23 that can receive infrared rays.
The infrared light emitted from the infrared transmission unit 21 is applied to the first concave shape portion 29, and the infrared light is reflected by the first concave shape portion 29.
The infrared receiving unit 23 can receive the reflected infrared light and detect its intensity.
With the configuration as described above, when water (liquid) accumulates in the first concave portion 29, the intensity of the infrared ray irradiated and reflected from the infrared transmitter 21 changes.
This change is determined by the control unit 57 via the infrared receiving unit 23 and water is detected.
In this way, the infrared communication unit 25 detects the presence or absence of water by irradiating water (liquid) attached to the first concave portion 29 with infrared rays and detecting the intensity of the reflected signal, so that the infrared communication unit 25 detects the water detection sensor 62. It is possible to act as.
The infrared communication unit 25 also has a function of performing infrared communication in addition to water detection.

FIG. 7 is an explanatory diagram of a fourth modification.
In particular, this is a modification of the water detection sensor 62 that detects water (liquid).
Further, the mobile phone 1 may have a voice input / output detection unit 35.
The voice input / output detector 35 is covered by the second cover member 37.
The second cover member 37 includes a second concave portion 39 that is formed on the surface of the housing and has a concave shape that can store a liquid.
The voice input / output detection unit 35 includes a speaker 31 that can output voice and a microphone 33 that can receive voice input.
The sound wave emitted from the speaker 31 is output to the second concave shape part 39, and the sound wave is reflected by the second concave shape part 39.
The microphone 33 can receive the reflected sound wave and detect its intensity.
With the configuration as described above, when water (liquid) accumulates in the second concave portion 39, the intensity of the sound wave output and reflected from the speaker 31 changes.
This change is judged by the control unit 57 via the microphone 33 to detect water.
In this way, the microphone 33 acts as the water detection sensor 62 by irradiating water (liquid) attached to the second concave portion 39 with sound waves and detecting the intensity of the reflected sound waves to determine the presence or absence of water. It becomes possible to make it.
The voice input / output detection unit 35 may also be used as a function of the voice input / output unit 53 that outputs conversation contents during a call in addition to water detection.

<Fifth Modification>

The reason is that the latest information is likely to be important.

According to the above embodiment, the mobile phone 1 includes the storage unit 70, the detection unit 60 that detects the external environment, and the control unit 57 that controls the storage unit 70 and the detection unit 60.
