Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to electronic devices such as handheld personal computers.

<Prior Art> The above-mentioned handheld personal computers are designed to be particularly compact for convenient portability, and many have already been proposed.

Normally, this type of computer is equipped with various peripheral devices such as printers and cassettes that are designed to be compact, and the system is designed to be able to be expanded as desired by connecting these devices.

However, previously proposed handheld personal computers connect these peripheral devices using cords, so if you try to carry them around while connected, the computer and peripheral devices inevitably come apart, making it very inconvenient to carry. In addition, it cannot be used immediately while being carried. This problem becomes more serious as the system increases, and in the past it was not possible to take full advantage of the great feature of the so-called handheld type.

<Purpose> Therefore, the purpose of the present invention is to provide a very practical electronic device in which the device body and peripheral devices can be integrated with the hard cover of the device body. .

<Example> The present invention will be explained in detail below based on the figures.

FIG. 1 is an external perspective view of a personal computer according to the present invention, and FIG. 2 is a diagram showing the relationship between the computer and a hard cover.

In the figure, A is a computer main body, D is a display section, K is a keyboard, M is a slide groove formed on both side walls of main body A, and H is a hard cover. The hard cover H has a U-shaped cross section, and its both ends fit into slide grooves M formed in the side wall of the main body A, so that it can slide in the direction of the arrow in the figure. E is a stopper, and this stopper is provided only on one side. Therefore, the hard cover H is removable from the main body A, and once removed from the main body A, it can also be attached to the bottom side of the main body A, as shown in FIG.

FIG. 3 is an external perspective view of the computer main body and peripheral devices integrated, and the method of using the hard cover will be explained based on this diagram.

P in the figure is a peripheral device, such as a printer, and slide grooves (not shown) are formed on both sides of the printer, similar to the main body A. Once the hard cover H is removed from the main body A, turn it over, and first slide the printer P into it until it reaches the stopper E. Next, slide the computer main body A up to the printer P. In this way, the computer main body A and the printer P, which is a peripheral device, can be easily integrated and can be carried around in this state, making it very convenient to carry. Moreover, since it remains integrated, it can be used immediately while being carried, greatly improving mobility with increased functionality.

Further, as shown in FIG. 4, the electrical connection between the printer P and the main body A is such that connectors ₁ and _C0 are provided on both, and the connectors are connected to each other when the slide is attached. Therefore, if other peripheral devices are also provided with slide grooves and connectors, they can be used integrally with the main body A instead of the printer P described above.

Figure 5 is a block circuit diagram when the above printer and main body are integrated. In the figure, PRT is the printer, PCU is the printer controller,
The printer controller is connected to the central processing unit CPU of main body A. DISP is the display section, KEY
is the key, and ROM and RAM are the memories.

FIGS. 6 to 8 are diagrams showing other embodiments. This embodiment is a case in which a plurality of peripheral devices and a computer main body are integrated. In the figure, _Z1 is a microcassette data recorder, and _Z2 is a printer.

Also, A _OUT is the output connector of main unit A, and Z _1IN.
Z _1OUT is the input/output connector of the microcassette data recorder Z ₁ , Z _2IN and Z _2OUT are the input/output connectors of the printer Z ₂ , and these connectors are attached to the printer Z ₂ , data recorder Z ₁ , and computer main body on the hard cover H. When A is connected to the slide device in order, they are connected as shown in FIG.

Fig. 8 is a block circuit diagram when connected as shown in Fig. 7. In this case, the central processing unit CPU of main unit A is connected to control the cassette CMT via the data line DATA, address line ADRS, and control line CNRL. The circuit CCU and the control circuit PCU of the printer PRT are electrically connected.

Note that the number of peripheral devices to be connected and the order in which they are connected are not limited to those in the above embodiments, and may be appropriately selected as necessary.

As described above, according to the present invention, the hard cover of the computer body can be used to easily integrate the computer body and peripheral devices, and the computer can be carried in an integrated state and used immediately when needed. Therefore, there is no risk of detracting from the advantages of the handheld type.

<Effects> As explained in detail above, the electronic device of the present invention protects the main body of the device, and also protects the main body of the device and the printer.
Since it is equipped with a sliding hard cover that can be used to integrate peripheral devices such as cassettes, the main body and peripheral devices can be easily integrated using the hard cover and carried or used.

Therefore, original mobility can be achieved with peripheral devices connected.
