FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention,
FIG. 2 is a perspective view showing the overall configuration of the electronic device according to one embodiment of the present invention, and FIG. 3 is a diagram showing the state of attachment and detachment of the electronic device according to one embodiment of the present invention.

As shown in FIGS. 2 and 3, an electronic device according to the present invention, for example, a personal computer (hereinafter referred to as a personal computer) is generally a PD for displaying calculation results and the like.
A display unit 2 having a display device 1 composed of P or LCD, etc.
And a main unit 4 having a keyboard 3 for inputting data and commands, and the like.
Is detachably connected by a male connector 5 disposed at the lower right end of the display unit 2 and a female connector 6 disposed at the upper right part of the main body unit 4 so as to face the male connector 5. A hard engaging piece 7 protrudes from the lower left end of the display unit 2, and is elongated along the side edge of the main body 4 at the upper left side of the main body 4 facing the engaging piece 7. When the opening 8 is formed and the male connector 5 is inserted into the female connector 6 and the display 2 and the main body 4 are connected, the engaging piece 7 is inserted into the opening 8 and disposed below the opening 8. Engaged with a locking portion (not shown). In addition, the female connector 6 and the locking portion are configured such that the display unit 2 is foldable with respect to the main body 4 by a hinge mechanism (not shown), and the engaging piece 7 rotates along the opening 8 with the locking portion as a fulcrum. I do.

On the other hand, as shown in FIG.
A type signal generator 9 for generating a type signal indicating the type of the display device 1; and a matching unit 10 for outputting a matching signal to the main unit 4 based on the type signal output from the type signal generator 9. Is built-in. As the display device 1, one selected from a plurality of different types of PDPs, LCDs, color PDPs, color LCDs, or the like is employed. The type signal generator 9 generates a type signal composed of a code signal in accordance with the type employed in the display device 1. The type signal generator 9 includes a register of a plurality of bits, and includes, for example, a PDP, an LCD, a color PDP,
Alternatively, if a color LCD is to be selected, it has a 2-bit configuration, the PDP is “00”, the color PDP is “01”, the LCD is “10”,
And the color LCD generates a type signal of "11".
In addition, the matching unit 10 controls the display device 1 when the display device 1 performs display.
A matching signal is output to the main body 4 in order to receive the required display signal and display power supply from the main body 4 in accordance with the type of.

The main unit 4 is composed of a keyboard 3, a display control unit 11, a power supply unit 12, and a microprocessor (not shown) for controlling the entire device as a personal computer. Are input to the display control unit 11 and the power supply unit 12 via the. Based on the matching signal, a display signal corresponding to the type of the display device 1 is output from the display control unit 11, and a PDP is output from the power supply unit 12 according to the type of the display device 1.
In this case, about 240 volts are supplied to the display device 1 in the case of the LCD, and several volts in the case of the LCD.

Next, the operation of the embodiment of the present invention having the above configuration will be described.

First, when a personal computer is used in an office where a commercial power supply can be used, power is supplied from the commercial power supply via an AC adapter (not shown), and a PDP that consumes a large amount of power but is easy to read is used as the display device 1. The display unit 2 is suitable. In this case, a type signal of code “00” is output from the type signal generating unit 9 to the matching unit 10, and the matching unit 10 outputs a matching signal corresponding to the type signal to the display control unit 11 and the power supply unit 12. . The display controller 11 controls the PDP according to the matching signal.
The display unit 1 outputs a display signal required by the display unit 1, and the power supply unit 12 supplies the display unit 1 with a display power of about 240 volts for driving the PDP. Upon receiving the display signal and the display power, the display device 1 performs an easy-to-read display which is a feature of the PDP.

On the other hand, when a personal computer is used in a place where commercial power is not available, the display unit 2 that uses a PDP that is easy to read but consumes a large amount of power is inappropriate, and an LCD that consumes little power and can be used for a long time with batteries is used. Display section 2
Therefore, the display unit 2 needs to be replaced.
In order to replace the display unit 2, the display unit 2 is pulled out in the direction of the arrow while the display unit 2 is held vertically, and the display unit 2 is detached, and then the engagement unit 7 is inserted into the opening 8 to use the LCD. Display 2
Push in the direction opposite to the direction of the arrow to mount. When an LCD is used as the display device 1, a type signal of code "10" is output from the type signal generator 9 to the matching unit 10 as in the case of the PDP, and the matching unit 10 The signal is output to the display control unit 11 and the power supply unit 12. The display controller 11 sends a display signal required by the LCD according to the matching signal to the display device 1.
The power supply unit 12 supplies the display device 1 with a display power of several volts for driving the LCD. Upon receiving the display signal and the display power, the display device 1 enters a low power consumption state which is a feature of the LCD, and the personal computer can be used for a long time.

In the above-described embodiment, the matching unit is built in the display unit. However, the present invention is not limited to this. For example, the matching unit may be built in the main body unit, or its function may be included in a microprocessor built in the main body unit. May be substituted.

In addition, the present invention is not limited to the above-described embodiment, and can be variously modified without departing from the gist of the present invention.

[Effects of the Invention] As described in detail above, according to the electronic apparatus of the present invention, a display signal and a display power matched to a display device selected based on a type signal of the display device are supplied to the display device. Thereby, the display device can be selected and used depending on the purpose of use and the use environment of the electronic device, and the user only needs to have one electronic device main body, which reduces the economic burden.
