[Problems to be solved by the invention]
By the way, normally, when searching for a portable telephone device placed in a bag, the bag is opened and a hand is put deep inside the bag. On the other hand, when checking a document in a bag or putting a document in the bag, even if you open the bag, you hardly put your hand deep inside the bag. In other words, opening the bag does not directly search for a portable telephone device. And in the said conventional technique, in a bright room etc., a location notification will be performed only by opening a bag. On the other hand, in the dark, location notification is not performed even if the bag is opened.
[0005]
SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to solve the problem that location notification of a portable telephone device is performed only by opening a bag.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, a portable telephone device according to the present invention is based on the notification means, a temperature sensor that detects the ambient temperature, and the ambient temperature detected by the temperature sensor. Control means for performing a search assisting operation in the notification means when the ambient temperature shows an increase change of a predetermined width or more with respect to a reference temperature after determining the hand-out / outside state. (Hereinafter referred to as the first configuration in this section).
[0007]
If it is the said 1st structure, a search assistance operation will be performed by detecting the temperature of the person's hand put in the bag, and a search assistance operation will be performed only by opening a bag. Can be prevented. Further, the search assisting operation is executed even in the dark where light does not reach in the cage.
[0008]
In addition, the portable telephone device of the present invention has a notification means, a temperature sensor for detecting an ambient temperature, and a bag mode, and when the ambient temperature shows an increase change of a predetermined width or more with respect to the reference temperature. And a control means for executing a search assisting operation by the notification means (hereinafter referred to as a second configuration in this section).
[0009]
In the first configuration described above, the mobile phone device itself performs a process of determining the hand-held / outside state of the mobile phone device based on the ambient temperature. Here, the out-of-hand state includes not only a state in which the portable telephone device is put in a bag but also a state in which the portable telephone device is placed on a desk or the like. In the second configuration, at the judgment of the person, the bag mode setting is not performed when the portable telephone device is placed on a desk or the like, and the bag mode setting is performed only when the portable telephone device is put in the bag.
[0010]
When a predetermined time has passed without the ambient temperature showing an increase change of a predetermined width or more with respect to the reference temperature, it is preferable to perform an update process using the ambient temperature at that time as the reference temperature.
[0011]
An optical sensor for detecting ambient brightness is provided, and when the ambient temperature shows an increase change of a predetermined width or more with respect to a reference temperature in a state where light can be detected by the sensor, the notification means assists the search. You may be comprised so that operation | movement may be performed (henceforth a 3rd structure in this term). In addition, an optical sensor for detecting the ambient brightness was provided, and the ambient temperature showed a change over a predetermined range with respect to the reference temperature when the ambient brightness once became a dark state and became a bright state. Sometimes the notification means may be configured to execute a search assisting operation (hereinafter referred to as a fourth configuration in this section).
[0012]
Here, in the first and second configurations described above, when a paper bag or the like wrapped with a warm object is placed on the bag, there is a possibility that the search assisting operation is executed by detecting the heat. If it is the 3rd composition and the 4th, since a search assistance operation will not be performed while it is not detected that an eyelid was opened with an optical sensor, the above-mentioned trouble can be prevented. However, the search assistance operation in the dark may not be possible. Further, in the fourth configuration, when the portable telephone device is continuously placed on a desk in a bright room or the like, the dark to bright state does not occur, so that the search assist operation condition due to temperature change is satisfied. Even so, there is an advantage that the search assistance operation is not performed.
[0013]
The informing means may be a light emitting unit that constitutes an image display unit or a light emitting unit that does not constitute an image display unit, and may be configured such that a lighting or blinking operation of the light emitting unit is performed as a search assisting operation. The notification means may be a sound generation means, and may be configured to output a buzzer sound, a melody, or a voice synthesis sound by the sound generation means as a search assisting operation. Further, the notification means may be a vibration generating means, and a vibration operation by the vibration generating means may be performed as a search assisting operation.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 3.
[0015]
FIG. 1 is a block diagram showing a portable telephone device of this embodiment. The operation unit 1 is provided with various keys such as a power key and a numeric keypad. By operating a predetermined key, the search assist operation can be set to be valid / invalid. In addition, if a predetermined key such as a governor mode key is provided, the portable telephone device can be put into the governor mode when the predetermined key is operated.
[0016]
The control unit 2 performs normal control as a portable telephone device such as outgoing / incoming control in the communication unit 3, and also performs control during valid setting of the above-described search assistance operation and control in the governor mode. In this control, processing for storing an output (A / D conversion data) of a temperature sensor 4 described later in the memory 2a is performed.
[0017]
The temperature sensor 4 is provided on the surface of the casing of the portable telephone device so that the ambient temperature can be detected. One temperature sensor 4 may be provided in a planar shape on the surface of the housing, but in this embodiment, a plurality of point-like temperature sensors 4 are provided, for example, at the four corners and the center of the side of the housing. It is provided in places. The temperature sensor 4 is not limited to a thermistor, and an infrared sensor can be used as the temperature sensor.
[0018]
The optical sensor 5 is provided on the surface of the casing of the portable telephone device so that ambient brightness can be detected. One optical sensor 5 may be provided in a planar shape on the surface of the housing, but in this embodiment, a plurality of dot-shaped optical sensors 5 are provided. The optical sensor 5 is not essential. The search assistance control that does not use the optical sensor 5 is shown in the flowchart of FIG. 2, and the search assistance control that uses the optical sensor 5 is shown in the flowchart of FIG.
[0019]
The vibrator 6 and the speaker 7 are usually provided as a portable telephone device. The backlight 8 is used when a liquid crystal panel is used as the image display unit. In the present invention, the vibrator 6, the speaker 7, and the backlight 8 are used as notification means. Of course, sound generating means other than the speaker 7 (ringing melody output unit, buzzer, etc.), LED (light emitting diode) provided on the EL display, numeric keypad, etc. when the screen display unit is an EL display or other places Light emitting means such as an LED can be used as notification means.
[0020]
When using the backlight 8 or the LED as a notification unit, the control unit 2 turns on or blinks as a search assisting operation. When the sound generating unit such as the speaker 7 is used as a notification unit, the control unit 2 As an operation, a buzzer sound, a melody, and a voice synthesized sound are output by the sound generation means, and when the vibrator 6 is used as a notification means, a vibration operation is performed as a search assist operation.
[0021]
Next, processing for the search assisting operation will be described based on the flowchart of FIG. When the search assist function is set to “valid” (YES in step S1), for example, it is determined whether there is no key operation for 20 seconds (step S2). If there is no key operation, the ambient temperature is measured using the temperature sensor 4 (step S3), and it is determined whether the portable telephone device is in the user's hand (step S4). For example, when the temperature sensor 4 detects a temperature of 30 ° C. or higher, it is determined that it is in hand. Of course, instead of a fixed temperature, the temperature may be changed to 32 ° C. in consideration of the ambient temperature. If it is determined that it is in the hands of the user, the process returns to step S3. When it is determined that it is not in hand (in the processing shown here, the state that the portable telephone device is not in hand is based on the premise that the portable telephone device is in the bag), the CPU Activates the search assist function (step S5), measures the ambient temperature using the temperature sensor 4, and stores it in the memory as a reference temperature (step S6).
[0022]
Then, the ambient temperature is further measured, and the difference between the ambient temperature measured this time and the reference temperature is output (step S7), and it is determined whether or not the ambient temperature shows an increase change of a predetermined width or more relative to the reference temperature. (Step S8). When it is determined that there is no increase change, the processes of step S7 and step S8 are repeated for a predetermined time (step S9), and when the predetermined time has elapsed, the process proceeds to step S6 to update the reference temperature.
[0023]
On the other hand, when it is determined in step S8 that there is a change in the increase and it is further determined that the vibration is effective (YES in step S10), the vibrator 6 is activated (step S11), NO is determined in step S10, and the speaker is effective. When determined (YES in step S12), sound is output from the speaker 7 (step S13). When NO is determined in step S12 and it is determined that the LCD backlight or the like is valid (YES in step S14), the LED, The LCD backlight is turned on (step S15). Then, when a certain time has elapsed or a key operation is performed by the user (YES in step S16), the search assist function is stopped (step S17).
[0024]
When the hand of a person is put in the bag while the portable telephone device is put in the bag, the temperature sensor 4 senses the temperature of the hand of the person and the search assisting operation is performed. Thus, it is possible to prevent the search assisting operation from being performed simply by opening the bag. Further, the search assisting operation is executed even in the dark where light does not reach in the cage. It should be noted that the process proceeds to step S12 after step S11, and the process proceeds to step S14 after step S13 so that one or more of the vibrator 6, the speaker 7, and the LCD backlight are operated. It may be.
[0025]
Next, another processing example for the search assisting operation will be described based on the flowchart of FIG. In this processing example, it is assumed that a predetermined key such as a governor mode key is provided on the operation unit 1, and the portable telephone device shifts to the governor mode when the predetermined key is operated. The portable telephone device determines whether or not the bag mode is ON (step S23), and when it is ON (in the process shown here, when the bag mode is ON, the user The ambient temperature is measured using the temperature sensor 4 and stored in the memory as a reference temperature (step S22).
[0026]
Then, the ambient temperature is further measured, and the difference between the ambient temperature measured this time and the reference temperature is output (step S23), and it is determined whether or not the ambient temperature shows an increase change of a predetermined width or more with respect to the reference temperature. (Step S24). If it is determined that there is no increase change, the processing of step S23 and step S24 is repeated for a predetermined time (step S25), and when the predetermined time has elapsed, the process proceeds to step S22 and the reference temperature is updated. Here, when the user operates the bag mode key and puts the portable telephone device into the bag, the ambient temperature of the portable phone device gradually decreases and approaches the temperature in the bag (decrease). In the meantime, it is not determined YES in step S24, and the reference temperature gradually approaches the temperature in the basket.
[0027]
If it is determined in step S24 that there is an upward change, it is determined whether or not light is sensed by the optical sensor 5 (step S26). When light is not sensed, the process returns to step S22. On the other hand, when the light is detected by the optical sensor 5 (YES in step S26) and it is determined that the vibration is valid (YES in step S27), the vibrator 6 is activated (step S28), and NO is determined in step S27. If it is determined that the speaker is valid (YES in step S29), sound is output from the speaker 7 (step S30). If NO is determined in step S29 and it is determined that the LCD backlight or the like is valid (step S31). YES), the LED and LCD backlight are turned on (step S32). Then, when a certain time has elapsed or there is a key operation by the user (YES in step S33), the search assist function is stopped (step S34).
[0028]
The above processing uses the optical sensor 5 in addition to the temperature sensor 4 and executes the search assist function when the optical sensor 5 cannot sense light even if the search assist function can be executed due to a temperature change. Not to do. Here, in the control example of FIG. 2, when a paper bag wrapped with a warm object such as a meat bun is placed on the bag, there is a possibility that the search assisting operation may be executed by detecting the heat. In the processing example, since the search assisting operation is not performed while the light sensor 5 does not detect light (that the eyelid is opened), the above problem can be prevented. However, the search assistance operation in the dark may not be possible.
[0029]
Further, in the processing example of FIG. 3, the search assist operation is simply performed in consideration of light detection. However, when the ambient brightness is once dark and becomes bright, and the ambient temperature is The search assisting operation may be executed when an increase change of a predetermined width or more with respect to the reference temperature is shown. According to this, in a state where the portable telephone device is continuously placed on a desk in a bright room or the like, a dark to bright state does not occur, so even if the search assist operation condition due to temperature change is satisfied, There is an advantage that the search assistance operation is not performed.
[0030]
【The invention's effect】
As described above, according to the present invention, it is possible to eliminate the problem that the search assisting operation of the portable telephone device is performed only by opening the bag and to realize a suitable search assisting operation.
