JPS5998227A - Pocketbook-type electronic computer - Google Patents

Abstract

PURPOSE:To attain excellent portability and operability and increase the number of degrees of freedom for improvement of system, by connecting card-type computer constituting elements into a pocketbook type and making them attachable to and detachable from a pocketbook constituting body electrically and mechanically. CONSTITUTION:A cover A1 and a back cover A2 of a pocketbook are formed by folding a sheet-shaped soft part, and a paper-shaped liquid crystal display device D and a touch-type thin keyboard K are arranged on the inside of the cover A1. A CPU is incorporated in a part of the inside of the cover A1 or the inside of the display device D or the keyboard K, and a paper-shaped battery BAT is incorporated in the back cover A2. Card-type computer constituting elements C1-C3 consist of, for example, an ROM, an RAM, etc., and their terminals X are brought elastically into contact with a bus line FX of a flexible print substrate F pressed in between a pair of pawls of holder parts H1 and H2. Thus, cards and the CPU are connected electrically and are attached and detached mechanically.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a notebook-type electronic computer or card-sized system computer.

<Prior art> With the dramatic progress in integrated circuit technology, electronic computers have been miniaturized from traditional stationary types to desktop types like personal computers, and even handheld and portable computers. gender is improving significantly. This trend clearly indicates a shift from the concept of installing and using a computer to a concept that emphasizes mobility, where each individual carries it and uses its functions anytime and anywhere.

However, in the past, as mentioned above, only the ``Non-Nandbelt'' type electronic computer was proposed.
Moreover, its size is still small enough that it can be stored in a large case and carried around.

<Purpose> In view of these conventional problems, the present invention aims to provide a novel notebook-type electronic computer that is excellent in portability and operability, and has a very large degree of freedom in system upgrades.

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

FIG. 1 is an external perspective view of a notebook-type electronic computer according to the present invention. In the figure, Al and A2 are the front and back covers of a so-called notebook formed by folding a sheet-like soft member in half. The inside type keyboard K of the cover A1 is arranged,
A central processing unit CP'U is built inside the cover or a part of the display device and the keyboard, and these are electrically connected.

On the other hand, on the back cover A2, there is a paper-like batch 1.1-
A BAT is built-in and electrically coupled to the CPU via a flexible board or the like.

C3 and C3 indicate card-type computer components, such as read-only memory ROM, read-write memory iAM, LSI built-in cards such as central processing unit CPU, and card-shaped display devices, and these are used as a notebook holder, which will be described later. It is constructed so that it can be electrically and mechanically attached to and detached from the section.

To talk a little bit about the LSI built-in card mentioned above, the conventional LSI card
While SI is formed based on the technical philosophy of simply making it as small as possible and enclosing it in resin, this LSI built-in card is formed by enclosing it in resin in the form of a notebook-sized card with a certain size. To put it simply, it is possible to incorporate a large number of LSI chips. In other words, by making it a card unit, the degree of integration is greatly improved,
It can be said that a large amount of information can be stored on one card. A terminal X (see FIG. 2) connected to the internal LSI and display device is exposed on the outer surface of this LSI built-in card and the card-like display device, and when attached to a part of the holder of the notebook, This terminal X and a pattern (pass line) FX under the flexible printed circuit board disposed in a part of the holder are formed so as to be in elastic contact with each other.

FIG. 2 is a detailed view of a portion of this holder.

The holders H1 and H2 are molded from synthetic resin, and have a bar-shaped base with one end of the card C as shown in the figure.
It has a Y-shaped cross-section with a pair of claws that elastically hold it. A through hole is bored in the base of the cover, and the wire W inserted through the through hole connects the cover to the front cover.
It is attached to the back cover AI + A2 so that it can be opened and closed.

F indicates a flexible printed circuit board in which a plurality of pass lines FX are arranged in parallel corresponding to each terminal X provided on the card, and this board is connected to a portion of each holder H1 as shown
, H2, and when the card C is installed between these claws, each terminal X of the card comes into elastic contact with the pass line FX of the flexible printed circuit board, and this pass line The LSI or display device of the card and the CPU are connected via the CPU.This situation is shown in FIG. That is, C+ to C4 indicate cards attached to the holder part H, and these are connected to the CPU via the pass line FX. Incidentally,
C1 is a ROM card, C2 is a RAM card, C3 is a display card for expanding the display area, and C2 is a CPU card for multi-CPU.

These cards C can be installed as appropriate depending on the purpose of use, and the system can be upgraded extremely freely depending on the selection.Furthermore, in the above embodiment, an example with a front cover AI and a back cover A2 is shown. However, you can use the card as a substitute for these. Also, instead of using the flexible printed circuit board F to connect the card and the CPU, a pass line FX may be printed directly between the claws of the holder part H, and this and the CPU may be connected by some method. Furthermore, the keyboard itself may also be formed in the form of a card.

<Effects> As described above, according to the notebook type electronic computer of the present invention, it is possible to provide a novel notebook type electronic computer that is excellent in portability and operability, and has great freedom in system upgrades.
