Description

  The present invention relates to a portable information processing apparatus in which a main body portion and a lid body portion are connected so as to be able to be turned upside down and can be input by a sub-input device provided on the lid body portion.

2. Description of the Related Art Conventionally, there has been proposed an electronic information processing apparatus in which a main body portion and a lid body portion are connected so as to be able to be turned upside down and can be input by a secondary input device provided on the lid body portion. In the device having such a configuration, the main input device of the main body portion may be erroneously operated when the lid portion is inverted, so that the input from the main input device is excluded when the lid portion is inverted. It is preferable.
And in the following patent documents, performing input control according to the rotation angle of the lid part is disclosed.
Japanese Patent Laid-Open No. 2002-255892

  The above publication is equipped with a panel sensor that detects a detection angle with respect to the operation surface of the main body of the display panel, and a preset rotation angle and a corresponding system control type are registered in advance in the system control setting unit. Is sent to the monitoring system to monitor whether the detected angle of the panel sensor matches the set rotation angle registered in advance in the system control setting unit, and the system control setting unit corresponding to the set angle A technique for instructing the PC system to execute the system control registered in the above is disclosed.

  According to the above technique, detailed condition setting and control setting are possible, but it is necessary to configure a program circuit, and the purpose is simply to disable input from the main input device when the lid is reversed Is over-spec and a simple configuration is desired.

The technology relating the rotation of the display and the magnetic switch is disclosed in the following patent documents.
JP 2002-244664 A

  In the above publication, in an apparatus in which an input device is rotatably mounted on a main body, a magnet is mounted on the input device, an electromagnetic switch is mounted on the main body, and the operation of the electromagnetic switch is performed when the input device is rotated (during input). A technique is disclosed in which the power is turned on.

  The above technique uses a magnetic switch for turning on and off the main power supply, and is not a technique for switching the input device.

  The present invention relates to a portable information processing apparatus in which a main body part and a lid part are connected so as to be able to be turned upside down and can be input by a secondary input device provided on the lid part. It is an object of the present invention to eliminate the input from the main input device provided in the main body when the is reversed, and to enable the input only from the sub input device provided in the lid.

The present invention comprises a main body portion provided with a main input device and a lid body portion provided with a sub input device, and the main body portion and the lid body portion are connected to each other by a hinge mechanism so as to be turned upside down. And the auxiliary input device are devices arranged on opposite surfaces when the lid is closed, and a magnetic switch that operates jointly is attached to the main body portion and the lid body portion, The portable information processing device is configured such that the input circuit from the main input device is turned OFF during inversion.
The “portable information processing device” includes a wide range of portable devices including input devices such as a keyboard and a touch panel, such as a personal computer, an electronic notebook, an electronic dictionary, an electronic learning machine, and a mobile phone.
Further, in the present invention, “inverted” does not necessarily mean that the lid portion is rotated 360 degrees, and means that the lid portion is rotated by 270 degrees or more and tilted toward the main body. The “hinge mechanism” does not necessarily include a structure in which the main body portion and the lid portion are directly connected, but also includes a structure in which the body portion and the lid body portion are indirectly connected via an arm or the like.

In addition to the configuration in which the main input device is a keyboard and the sub input device is a touch panel provided on the display panel (Claim 2), both the main input device and the sub input device are a display panel or a keyboard. It is.
The magnetic switch is a combination of a magnet and a Hall IC (Claim 3), so that high switching accuracy can be obtained, but a reed switch may be used. In short, any configuration may be used as long as the change in the positional relationship between the main body and the lid due to the rotation of the lid is detected by magnetism, and the circuit of the main input device is turned on / off.
Therefore, the mounting position of the magnetic switch is not limited as long as the above action can be obtained.

  According to the present invention, in a state where the main body portion is horizontally placed and the lid body portion is inclined with respect to the main body portion, the information is input by an input device such as a keyboard provided in the main body portion. Can do. When the lid body portion is inverted and the input device of the lid body portion is to be used, the input from the input device of the main body portion is restricted by the operation of the magnetic switch. Accordingly, even when the device of the present invention is held in the hand and the input device of the lid is used, even if a finger touches the input device of the main body, no input is made and the possibility of erroneous input is eliminated.

  Connection support rods 2 and 2a are provided on both sides of one long edge portion 1a of the main body portion 1 which is a square plate body, and the other one of the lid portion 3 which is the same as the main body portion 1 is a square plate body. Connecting support rods 4 and 4a project from both sides of the long edge portion 3a, and both sides of the plane rectangular connecting plate 5 are rotatably attached to the connecting support rods 2 and 2a and the connecting support rods 4 and 4a. In addition, the main body 1 and the lid 3 are rotatably connected by the connecting plate 5.

  A keyboard 6 is provided on the back surface (surface hidden when closed) of the main body 1, and a display panel 7 is provided on the back surface (surface hidden when closed) of the lid 3. There is a touch sensor attached to the display panel 7 so that touch panel input is possible. Further, as indicated by reference numerals 8 and 9 in the figure, button type input devices are also provided as appropriate.

A Hall IC 10 is attached to the long edge 1a side of the substrate housed in the main body 1, and a magnet is provided on the long edge 3a side of the lid 3 at a position corresponding to the Hall IC. 11 is decorated.
The magnetic switch 12 composed of the Hall IC 10 and the magnet 11 has a circuit configuration as shown in FIG. 3 and is a state in which the main body 1 is held horizontally and the lid 3 is raised obliquely with respect to the main body. , The input from the keyboard 6 and the input from the display panel 7 of the lid are made possible. When the lid 3 is reversed and the Hall IC 10 and the magnet 11 come close to each other, the input from the keyboard 6 is restricted. Only input from the input device of the lid 3 such as the panel 7 is allowed.

  In FIG. 3, when the magnetic switch 12 composed of the Hall IC 10 and the magnet 11 is in the ON state, the input power source Vs input from the gate 1 is output from the gate 2 as the Open Drain Voltage Q, and the keyboard is disabled. .

According to the present invention, when an attempt is made to input from the display panel or the like provided on the back surface of the lid portion by inverting the lid portion, the input from the keyboard or the like of the main body portion is restricted by the operation of the magnetic switch. Therefore, when the lid is reversed and the hand is placed on the main body to support it, no input is made even if a finger touches the keyboard or the like. Therefore, it is possible to firmly hold the device and input from the lid portion without worrying about erroneous input from the input device of the main body.
As described above, according to the present invention, with a simple configuration in which the magnetic switch is mounted, the input operability when the lid portion is inverted can be improved, and the present invention has industrial applicability.
