As one form of this portable information terminal, there is a foldable information terminal having a structure in which an upper case and a lower case are connected to each other by a hinge portion so as to be opened and closed. This foldable information terminal has a feature that it can be made compact by opening two upper and lower cases that overlap each other when in use, and folding the two upper and lower cases when not in use. In this foldable information terminal, when the upper and lower cases are opened by the user from the state where the upper and lower cases are closed and folded, it is detected and the LEDs are automatically turned on, while the upper and lower cases are opened. LED that was lit by detecting when the upper and lower cases were closed and folded by the user from the state
It is known that there is a function for turning off the LED (hereinafter referred to as an LED turning on / off control function).

As described above, the conventional foldable information terminal having the LED on / off control function automatically LE when the user opens / folds the upper and lower cases (hereinafter referred to as opening / closing operation).
Since D is turned on / off, user operability and power saving can be improved. However, some users of the foldable information terminal repeat the opening / closing operation more than necessary in a short time in order to enjoy the feeling of the opening / closing operation or simply to make a personal habit. Even in such a usage state, when the user opens the upper and lower cases, the LEDs are always turned on, and when the upper and lower cases are closed, the LEDs are always turned off, which causes unnecessary power consumption. It was.

In order to solve this problem, this foldable information terminal automatically includes LEs when the upper and lower cases are folded and then the upper and lower cases are opened after a predetermined time.
When D is turned on and the upper and lower cases are opened before a predetermined time elapses, it is known that there is a function of turning on the LED on condition that a key input is performed (for example, Patent Documents). 1).
JP 2002-300270 A (page 3-5, FIG. 3)

The foldable information terminal having the LED on / off control function determines whether to turn on the LED depending on whether or not the predetermined time has elapsed. Therefore, when the upper and lower cases are opened before the predetermined time has elapsed, , Always do not light the LED. For this reason, there is a problem in that the LED is not turned on if it is performed in a short time even if the opening / closing operation is repeated too few times to be considered to be due to a user's habit or the like. In addition, if the upper and lower cases are opened before the predetermined time has elapsed, the LED is not lit until a key input is detected.
There was a problem that the user had to perform a separate operation in order to light up.

Therefore, the present invention eliminates this problem and has an LED lighting / extinguishing control function.
When a user repeatedly opens and closes a predetermined number of times in a short time, the LED is not turned on to save power, and the upper and lower cases are used for the user to use the folding information terminal. Even when it is open, it is automatically set to L without any separate operation.
An object is to provide an information terminal capable of lighting an ED.

In order to achieve the above object, an information terminal according to the present invention includes a first case, a second case attached to the first case so as to be openable and closable, and at least the first case or the second case. In an information terminal comprising a display unit provided on one side and a light emitter that illuminates the display unit, state detection means for detecting that the first case and the second case have changed from a closed state to an open state; When the state detecting means detects that the state has been changed to the open state, the counting means for counting the number of times the state has been changed to the open state, and when the state detecting means has detected that the state has been changed to the open state, A first timing unit that starts counting a predetermined time, and when the state detection unit detects the open state, it is determined whether or not the number of the counting unit has reached a predetermined number, and the counting Number of means When the predetermined number of times has not been reached, the light emitter is turned on. On the other hand, when the number of times of the counting means has reached the predetermined number of times, the first time counting means further includes the first predetermined time. And a lighting control means for turning on the light emitter when it is determined that the first predetermined time has been measured.

As described above, according to the communication terminal of the present invention, the number of times that the first case and the second case are opened is counted, and the first case and the second case are opened. When the number of times has not reached the predetermined number, the light emitter is turned on. On the other hand, when the number has not reached the predetermined number, the light emitter is turned on after the first predetermined time has elapsed. As a result, when the opening / closing operation is repeatedly performed within a short time, it is possible to control not to turn on the light emitter, and power saving can be achieved.

Next, the operation of the first embodiment will be described with reference to the flowcharts of FIGS.

The state detection means 231 of the microprocessor 23 constantly monitors whether the folding terminal has changed from the closed state to the open state from the open / close detection switch 39. At this time, the number of times detected by the counting means 233 (hereinafter referred to as the number of times of opening) is “0”, and the number of times of opening X = 0 is stored in the RAM 22 (step 4a in FIG. 4).

When the state detection unit 231 detects that the folding terminal has changed from the closed state to the open state (Yes in Step 4b in FIG. 4), a lighting control unit 232 generates a detection signal indicating that the state has changed from the closed state to the open state. And the counting means 233 is notified. The counting means 233 adds 1 to the number of times of opening, sets the number of times of opening X = 0 + 1, and notifies the lighting control means 232 of this number of times (step 4c in FIG. 4).

Next, the lighting control means 232 determines whether or not the number of opening times X is 2 or more (step 4d in FIG. 4). Since the number of times of opening X = 1 at this time, it is determined that the number of times of opening X is not 2 or more (No in step 4d in FIG. 4), and the lighting control unit 232 lights the display unit LED 331 and the like (step 4e in FIG. 4). ). This makes it easier for the user to visually recognize the display unit 33 and the like.

Next, the state detection means 231 monitors whether or not the folding terminal has changed from the open state to the closed state, depending on the state of the open / close detection switch 39 (step 5a in FIG. 5). The state detection means 231 is
When it is detected that the folding terminal has changed from the open state to the closed state (Yes in step 5a in FIG. 5)
), The lighting control means 232 is notified of a detection signal indicating that the state has changed from the open state to the closed state. When the notification of the detection signal is received, the lighting control unit 232 turns off the display unit LED 331 (step 5b) and returns to step 4b in FIG. 4 (step 5c in FIG. 5).

In step 4b of FIG. 4, when the state detection means 231 detects that the folding terminal has changed from the closed state to the open state (Yes in step 4b of FIG. 4), it indicates that the state has changed from the closed state to the open state. A detection signal is sent to the lighting control means 232 and the counting means 233. Counting means 2
When the detection signal is notified, 33 adds 1 to the opening number X (opening number X = 1 + 1 = 2), and notifies the lighting control means 232 of this number (step 4c in FIG. 4).

Next, the lighting control means 232 determines whether or not the number of times of opening X is a predetermined number of 2 or more (step 4d in FIG. 4). Since the number of times of opening X = 2 this time, the lighting control means 232
It is determined that the number of times of opening X is equal to or greater than a predetermined number of 2 (Yes in step 4d in FIG. 4).

Next, the lighting control means 232 checks the time measured by the first time measuring means 234 and determines whether or not the time measured by the first time measuring means 234 is 2 seconds or more (step 4f in FIG. 4). .

The first time measuring means 234 notifies the state detecting means 231 of the notification when the state detecting means 231 detects the change of the folding terminal from the closed state to the open state in step 4b of FIG. The timing is started in response to the reception of this notification. When the time-measurement time of the first time-measurement means 234 has not reached 2 seconds (first predetermined time) (No in Step 4f in FIG. 4), the lighting control means 232 then turns from the state detection means 231 to the folding terminal. It is determined whether or not a notification indicating that the state has changed from the open state to the closed state is received (step 4g in FIG. 4), and if the result of this determination has not been received (No in step 4g in FIG. 4) Returning to step 4f, it is checked whether the time keeping time of the first time measuring means 234 is 2 seconds or more.

Here, when the lighting control unit 232 determines that the time measured by the first time measuring unit 234 is 2 seconds or more (Yes in step 4f in FIG. 4), the display unit LED 331 is turned on (FIG. 4).
Step 4e). That is, since it is determined that the user is in an open state for 2 seconds or more, it is an input operation or a display operation by the user, the display unit LED 331 and the like are turned on.

On the other hand, in step 4g of FIG. 4, when the lighting control unit 232 receives a notification from the state detection unit 231 indicating that the folding terminal has changed from the open state to the closed state (FIG. 4).
In step 4g), the process returns to step 4b in FIG.

Thereby, when the user opens the folding terminal for the first time (when the number of times of opening is one), the display unit LED 331 and the key input unit LED 361 are immediately turned on, but two seconds have elapsed from the opened state. If it is closed before and reopened (when the number of times of opening is 2 or more), the display unit LE
The D331 and the key input unit LED 361 are not turned on.

Therefore, when the user repeats the opening / closing operation for a short period of time, it is considered that the opening / closing operation is unnecessary and it is not necessary to illuminate the display unit LED 331 or the like.

On the other hand, when the open state is maintained for a predetermined time or more, it can be assumed that the user is using the folding terminal, for example, confirming the display contents of the display unit 33, so the lighting control means 232 displays the display unit. Lighting of LED331 etc. is maintained.

As described above, according to the first embodiment, although the folding terminal has the LED lighting / extinguishing control function, the display unit LED 331 and the like are not turned on after a predetermined number of times of opening / closing repeatedly. When the user opens the foldable terminal to use the folding terminal, the display unit LED331 and the like are automatically turned on without performing a separate operation when a predetermined time elapses.

Here, the predetermined number of times counted by the counting means 233 is “2”, but this value can be changed to a predetermined number of times of two or more. The first predetermined time measured by the first time measuring means 234 is 2 seconds, but this time can also be changed to the predetermined time.

The lighting of the display unit LED 331 and the key input unit 361 is not limited to the case where both are lit, and only one of them may be lit.

In the second embodiment, the second time measuring means 235 measures the elapsed time from the time when the folding terminal is opened, and the measured time has passed a second predetermined time (for example, 3 seconds). In this case, the open count counted by the counting means 233 is returned to “0”. Here, the second time measuring means 235 measures the elapsed time from when the folding terminal is opened until the next folding terminal is opened, and each time the folding terminal is opened, the time counting time is an initial value. Reset to 0 and measure the time.

The lighting control means 232 determines whether or not a detection signal indicating that the folding terminal has changed from the closed state to the open state has been sent from the state detection means 231, and when not notified (step 4 b in FIG. 6). No), the process proceeds to step 6a in FIG. In this case, the number of open times detected by the counting means 233 is maintained. Here, the lighting control unit 232 determines whether or not the number of times of opening detected by the counting unit 233 is “0”. If it is not “0” (No in Step 6a in FIG. 6), the lighting control unit 232 proceeds to Step 6b in FIG. move on.

  Next, the lighting control unit 232 checks the time measured by the second time measuring unit 235.

The second time measuring means 235 receives a detection signal indicating that the folding terminal has changed from the closed state to the open state from the state detecting means 231 in step 4b of FIG. 6, and in response to the reception of this detection signal. The timing has begun. The lighting control means 232 is configured so that the time measuring time of the second time measuring means 235 is 3 seconds (
(Second predetermined time) is reached, and if it is determined that 3 seconds have been reached (Yes in step 6b in FIG. 6), the number of times of opening is returned to “0” and the number of times of opening X = 0 is set. It memorize | stores in RAM22 (step 6c). Then, the process returns to step 4b in FIG.

On the other hand, if it is determined in step 6a in FIG. 6 that the number of times of opening is 0 (Yes in step 6a in FIG. 6), or the time measured by the second time measuring means 235 in step 6b in FIG. When it is determined that the second predetermined time has not been reached (No in step 6b in FIG. 6)
Return to step 4b in FIG.

By the way, if it is determined in step 4b in FIG. 6 that the folding terminal has been opened, and it is determined in step 4d in FIG. 6 that the number of times of opening is not “2” or more, the lighting control means 232
After the display unit LED 331 and the key input unit LED 361 are turned on (step 4 in FIG. 6)
e) Go to step 5a in FIG. In this step, the lighting control unit 232 determines whether or not the detection signal indicating that the folding terminal has changed from the open state to the closed state is notified from the state detection unit 231, and determines that it has not been notified ( Step 5a in FIG. 7), FIG.
Proceed to step 7a. Here, the lighting control unit 232 determines whether or not the number of times of opening counted by the counting unit 233 is “0”, and determines that the number of times of opening is not “0” (step 7).
a) No), go to Step 7b of FIG.

In step 7b of FIG. 7, the lighting control means 232 checks the time measured by the second time measuring means 235. This second time measuring means 235 is the state detecting means 23 in step 4b of FIG.
When the folding terminal 1 detects a change from the closed state to the open state, it receives a notification of a detection signal indicating that and starts timing in response to reception of this notification. The lighting control means 232 determines whether or not the time measured by the second time measuring means 235 has reached 3 seconds (second predetermined time), and determines that it has reached 3 seconds (step in FIG. 7). (Yes in 7b) The number of times of opening is returned to “0”, and the number of times of opening X = 0 is stored in the RAM 22 (step 7c). Then, the process returns to step 5a in FIG.

On the other hand, when it is determined in step 7a in FIG. 7 that the number of times of opening is 0 (Yes in step 7a in FIG. 7), or the time measured by the second time measuring means 235 is 3 seconds (second predetermined time). When it is determined that it has not been reached (No in step 7b in FIG. 7), the process returns to step 5a in FIG.

Thereby, when the user opens the folding terminal for the first time (when the number of times of opening is one), the display unit LED 331 and the key input unit LED 361 are immediately turned on, but two seconds have elapsed from the opened state. If it is closed before and reopened (when the number of times of opening is 2 or more), the display unit LE
The D331 and the key input unit LED 361 are not turned on. Therefore, when the user repeats the opening and closing operation in a short period of time, it is considered that the opening and closing that does not need to be illuminated,
The display LED 331 and the like can be turned off immediately.

On the other hand, when the open state is maintained for the first predetermined time (2 seconds) or more, the user displays the display unit 3.
Therefore, the lighting control means 232 maintains the lighting of the display unit LED 331 and the like.

Furthermore, the interval between the first opening of the folding terminal and the next opening is the second predetermined time (3 seconds).
If the time has passed, it is considered that the user has not repeated the opening / closing operation for a short period of time. When the terminal is opened, the display LED 331 and the like can be turned on immediately.

As described above, according to the second embodiment, the first predetermined time elapses after a predetermined number of times of opening / closing repeatedly, even though the folding terminal has the LED lighting / light-off control function. Even if the display unit LED or the like is not lit until after the predetermined number of times, if the folding terminal is opened after the second predetermined time has elapsed, the original LED lighting / extinguishing control function is performed.

As described above, according to the second embodiment, although it is a folding terminal having an LED lighting / extinguishing control function, the display unit LED 331 and the like are not turned on after a predetermined number of times of opening / closing repeatedly. When the user opens the foldable terminal to use the foldable terminal, the display unit LED331 and the like are automatically turned on without performing a separate operation after the first predetermined time has elapsed, and Even after the predetermined number of times, when the folding terminal is opened after the second predetermined time has elapsed, the original LED on / off control function is performed.
