  According to the present invention, each of the information processing devices includes an input unit and a display unit, and the input unit and the display unit are selectively connected between the built-in information processing unit and the externally connected information processing unit. An information processing system that can be used can be provided.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings. The present embodiment is a personal computer that can selectively use a built-in information processing means and an externally connected information processing apparatus with a built-in input means and display means.

  FIG. 1 is a diagram illustrating a configuration of an information processing system according to the present embodiment. Referring to FIG. 1, the information processing system of this embodiment is configured by connecting an information processing apparatus 1 and an information processing apparatus 2. The information processing apparatus 1 has the information processing means 10, the display means 11, the display switching means 12, the input switching means 13 and the input means 14 in the same housing, and the information processing apparatus 2 is similarly configured with the information processing means 20 The display means 21, the display switching means 22, the input switching means 23 and the input means 24 are provided in the same casing.

  The information processing apparatus 1 is a notebook personal computer, for example. The information processing apparatus 2 may be a notebook personal computer similar to the information processing apparatus 1, or a computer having display means and input means more limited than the notebook personal computer, such as a PDA (Personal Digital Assistant). It may be a simple device.

  The information processing means 10 performs information processing based on user operation information input from the input means 14 and outputs screen information. Specifically, the information processing means 10 can be constituted by a CPU and a DRAM. The information processing means 10 executes functions such as a display control unit 101 that creates screen information to be displayed on the display unit 11 described later, and an input control unit 102 that receives input information from the input unit 14 described later. Is realized.

  The display means 11 receives the input of screen information to be displayed and displays it so as to be visible to the user. Specifically, the display means 11 can be configured by a liquid crystal display, a plasma display, an organic EL display, or the like.

  The display switching unit 12 selects and switches screen information to be output by the display unit 11 from the input information. Specifically, the display switching means 12 has a plurality of inputs and one output, and can be configured by a switch in which one of the plurality of inputs is connected to the output. The output of the display switching means 12 is connected to the display means 11. The switch may be a switch that switches the connection mechanically or an electronic switch.

  The input switching unit 13 selects and switches a destination to which user operation information input from the input unit 14 described later is output. Specifically, the input switching means 13 has a single system input and a plurality of systems of outputs, and can be configured by a switch whose input is connected to one system of the plurality of systems of outputs. The input of the input switching means 13 is connected to the input means 14 described later. The switch may be mechanical or electronic as in the display switching means 12.

  The input means 14 receives a user operation as an input and outputs it as information. Specifically, the input means 14 can be configured by a keyboard or a touch pad.

  The configuration of the information processing apparatus 2 connected to the information processing apparatus 1 is the same as that of the information processing apparatus 1 except for the display switching unit 22 and the input switching unit 23, and thus the description of the common configuration is omitted.

Specifically, the display switching means 22 can be configured by a switch having one input and a plurality of outputs, and the input is connected to one of the plurality of outputs.

  The input switching unit 23 selects and switches operation information to be input to the information processing unit 20 from the input information. Specifically, the input switching means 23 has a plurality of inputs and one output, and can be configured by a switch in which one of the plurality of inputs is connected to the output.

  In response to the connection with the display switching means 12 or the input switching means 13, the display switching means 22 outputs screen information to the outside of the casing, and the input switching means 23 sends the information processing means 20 to the outside of the casing. If the operation information input from is input, the information processing apparatus 2 can be used without confusion.

  Further, the switching state of the display switching means 12 or the input switching means 13 can be detected by the information processing apparatus 2 by connecting the information processing apparatus 1 and the information processing apparatus 2 with a signal line, and the display switching means 12 or input. In response to the switching means 13 being switched to the information processing apparatus 2, the display switching means 22 outputs screen information to the outside of the casing, and the input switching means 23 causes the information processing means 20 to switch to the casing. Operation information input from the outside can also be input. In this way, the user can use the information processing apparatus 2 in any switching state.
