2. Description of the Related Art Conventionally, an information terminal with a touch panel of this type has been disclosed in, for example,
As shown in Japanese Patent Application Publication No. 618, by storing a touch pen in a touch pen storage unit, a sleep mode state is started, or a power supply is automatically turned off after a certain period of time in the sleep mode state, thereby suppressing current consumption. I was Also, the power was turned off by removing the touch pen from the touch pen storage unit.

[0003]

The first problem is that the power cannot be turned off immediately by simply storing the touch pen.

[0004] The reason for this is that after detecting that the touch pen has been stored, the system temporarily shifts to the sleep mode state, and after a predetermined time, automatically turns off the power.

A second problem is that the storage position of the touch pen in the sleep mode is the same as the storage position of the touch pen in the power-off state.

[0006] The reason is that, when the storage of the touch pen is detected, the state shifts to the sleep mode state, and the power is automatically turned off after a certain period of time.

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of the configuration of the first embodiment of the present invention, and FIG. 2 is a flowchart showing the operation of this embodiment.

Referring to FIG. 1, according to a first embodiment of the present invention, a case 1 constituting an outer shape of an information terminal with a touch panel and a control unit printed circuit assembled by electronic circuits for controlling the entire terminal are provided. The substrate 2, a touch pen storage section 7 provided to store the touch pen 5 in a predetermined location of the case 1, and the touch pen 5 provided near the touch pen storage section 7 of the case 1 and more than half of the touch pen 5 is stored in the predetermined storage location A detection switch 4 that is turned on when the touch pen 5 is turned on when the touch pen 5 is completely stored in a predetermined storage space, a touch switch 8 that can be turned on when the touch pen 5 is turned on, a touch panel 8 that can input coordinates with the touch pen 5, and a touch panel 8. Central processing unit that processes the output from the PC and the input information such as the detection switch back 3 and the detection switch front 4 and controls the entire terminal Made with a door. Note that a micro switch, which is a mechanical switch, is used as the detection switch back 3 and the detection switch front 4.

Next, the operation of this embodiment will be described with reference to FIG.

First, the central processing unit 6 monitors the state of the front of the detection switch 4 (step 101;
In FIG. 2, the step is indicated as S. If the detection switch 4 is off, step 101 is repeated. When the front of the detection switch 4 is turned on, the central processing unit 6 controls the electronic circuit arranged on the arrangement board 2 on the control unit printed circuit board 2 so as to shift to the slow mode for reducing the current consumption ( Step 102). Next, the state of the detection switch back 3 is monitored (step 103). If the detection switch 3 is on, the central processing unit 6 performs control to turn off the power (step 104).

Even when the power is turned off, the central processing unit 6 maintains a state in which it can respond to a specific interrupt process. Here, a specific interrupt refers to the state of the detection switch back 3. The central processing unit 6 in which the power is turned off monitors the state of the detection switch back 3 (step 105). If the third detection switch is on, step 105 is repeated. When the detection switch 3 is turned off, the central processing unit 6 controls to shift to the slow mode state (step 102). If the detection switch 3 is off at step 103, the state of the detection switch 4 is monitored (step 106). If the front of the detection switch 4 is on, the process returns to step 103 to monitor the state of the detection switch back 3. If the detection switch 4 is off, the central processing unit 6 turns on the power (step 10).
7).

Next, a specific example of the operation in the configuration of FIG. 1 will be described with reference to FIG.

Normally, if the user is using the information terminal with a touch panel, the touch pen 5 is taken out of the touch pen housing 7 and is in the hand in use. Therefore, the front of the detection switch 4 and the rear of the detection switch 3 are turned off, and the power is turned on (step 101). Here, in the case of simply reading the display unit during use or the like, there is no need to use the touch pen 5.
Since it is not necessary to use the touch pen 5, if the touch pen 5 is half stored in the touch pen storage unit 7, it is not necessary to hold the touch pen 5 in the hand so that the hand can be used. Be free and convenient. In addition, it is more convenient to take out the touch pen 5 next than to completely store the touch pen 5. In this state,
The front of the detection switch 4 monitored in step 101 is turned on, and the terminal shifts to the slow mode (step 1).
02). Since the mode has shifted to the slow mode, the current consumption is reduced. Further, monitoring is performed to determine whether the detection switch 3 is on (step 103). Since the touch pen 5 is stored only halfway, the detection switch 3 is turned off.
The monitoring before the detection switch 4 is performed (step 106).
Here, when the user wants to read the next page, when the user takes out the touch pen 5 and operates the touch panel 8, the detection switch 4 is turned off, the power is turned on, and the process exits from the slow mode (step 107).

When the user finishes using the information terminal and completely stores the touch pen 5 in the touch pen housing 7, both the front of the detection switch 4 and the rear of the detection switch 3 are turned on, so that the power is turned off ( Step 104). Thereafter, the user attempts to use the information terminal and touch pen 5
Is removed, the central processing unit 6 temporarily shifts to the slow mode (step 102) and performs control to turn on the power (step 107).

In the above embodiment, the microswitch is used as the detection switch.
Instead, a light detection switch, for example, a light emitting diode and a photo sensor may be arranged to face each other, and the touch pen 5 passing between them may be detected.

Next, a second embodiment of the present invention will be described with reference to FIG.

FIG. 3 is a plan view of the configuration of the second embodiment of the present invention.

And a detection switch 14 provided near the touch pen storage portion 7 of the case 1 and located at a position where the magnet-filled touch pen 16 is stored in a predetermined storage space by half or more, and the magnet-filled touch pen 16 is completely placed in the predetermined storage space. A detection switch 13 that is turned on when stored, a touch panel 8 on which coordinates can be input by a magnet-inserted touch pen 16, an output from the touch panel 8, and input information such as a detection switch 13 and a detection switch front 14. And a central processing unit 6 for controlling the entire terminal.

Here, the control unit printed circuit board 2 shown in FIG.
For the detection switch depth 13 and the detection switch front 14 disposed in the above, a reed switch that turns on by detecting the magnet of the permanent magnet 15 is used. The detection of the storage position of the magnet-inserted touch pen 16 by the reed switch, and the operation of shifting to the slow mode state and the power-off state based on the detection result are the same as in the first embodiment.

[0025]

The first effect is that the use time of the battery is extended.

The reason is that, in an operation that does not require a large amount of current consumption, the current consumption is automatically reduced simply by putting the touch pen in the touch pen storage section.

The second effect is that the power can be turned off quickly.

The reason is that it is possible to determine that the touch pen is completely stored in the touch pen storage unit, and when the touch pen is completely stored, it can be determined that there is no intention to use the touch pen, and the power is immediately turned off. This is because it can be done.
