Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to portable business equipment such as handheld terminals, personal computers, word processors, etc., and particularly relates to a method for attaching and detaching an external storage card thereto. External storage cards include magnetic cards, IC cards, memory cards, and the like.

[Conventional technology]

External storage cards have traditionally been an expansion of the memory in question.

It has been used for purposes such as storing information after the power is turned off, but
With the arrival of the new media era, the amount of waste paper used has increased. For this reason, although it is necessary to frequently attach and detach the external storage card, the conventional attachment and detachment method has been as shown in FIG. 6, for example. The relationship between the size of the main body and the size of the card was as shown in Figure 7.

[The point at which the invention attempts to solve]

In the above-mentioned conventional example, frequent replacement of external storage cards was not taken into account, and the operability of attaching and detaching the card was extremely poor. In addition, although the size of this type of card is almost constant, it is not consistent with the main body, and the size is extremely irrational (the ratio of the card size to the main body size). There was a lot of wasted space in the implementation.

An object of the present invention is to provide an easy-to-operate method for attaching and removing an external memory card that allows for quick exchange of cards while operating a portable business machine, assuming frequent exchange of external memory cards while using a portable business machine. There is a particular thing. Another object is to match the size of the main body of the business machine with the size of the card, and to effectively mount the cards on the main body to maximize the number of cards that can be installed.

[Means for solving problems]

The above object is achieved by allowing the external storage card to be attached to and removed from the back side of the portable business machine from both left and right sides, and by making the vertical width of the business machine approximately equal to the width of the external storage card. Further, by aligning the operating side end surface of the external storage card with the left and right side surfaces of the business machine, operability is further improved.

[Effect]

When it becomes necessary to replace an external storage card while operating a portable business machine, the user can reach the approximate location of the external storage card without having to turn over the main body of the business machine and check the position of the external storage card. . By simply pulling out the external storage card to the right or left, it can be removed from the main body, eliminating the need for extra operations. When attaching and detaching from the right side, there is no need to change hands, and the external storage card can be removed smoothly. The same applies when installing an external storage card into a portable business machine.

〔Example〕

As an embodiment of the present invention, an example of attaching and detaching a memory card to a portable computer is shown in Figures 1 to 5 below.
This will be explained using figures.

The portable computer 10 is equipped with a liquid crystal display [18], a numeric input keyboard 19, a character input keyboard 20, a power ON/OFF switch 21, etc. on the front surface 12.

- The back surface 13 is provided with two connectors 22 for storing memory cards 30, and a guide 24 is provided at the end of the connector 22.

To install the memory card 30 into the portable computer 10, move the edge 31 of the memory card 30 into the guide 24.
the memory card 30, and then push the memory card 30 toward the connector 22 to attach it. In the installed state, the operating side end 32 of the memory card 30 substantially coincides with the right side 15 and left side 16 of the portable computer 10, forming the same surface.

A board 33 containing an IC is integrally attached to the surface of the memory card 30 opposite to the operation side, and a connection terminal 34 is provided at the end of the board 33.

When attaching the memory card 30 to the connector 22,
The spring-shaped pin 23 inside the connector 22 comes into contact with the connection terminal 34 to be in the attached state. A sectional view of the connector section with the memory card 30 attached is shown in FIG.

The memory card 30 stores read-only general-purpose programs such as system software, word processor function software, tabulation software, etc., and also stores user-created programs, various data, etc. that can be used as recording memory. has been done. These memory cards 3
0, select one containing the necessary software and set it in the portable computer 10.

In this embodiment, the portable computer 1o is a horizontally elongated device, with a horizontal length approximately twice the total length of a 3° memory card (including the size of the connector), and a vertical width approximately equal to the width of the memory card. Equal (width of guide 24 is added)
, up to two memory cards 30 can be installed. That is, the rear surface 13 of the portable computer 10 is effectively utilized for implementation.

According to this embodiment, there are further effects as follows. In other words, as the number of memory cards 3o increases, it becomes necessary to replace them frequently, and even when the memory cards 30 are inserted and removed during operation, the width of the main body and the width of the cards must be approximately the same, and the edges must be aligned. This allows the approximate location of the memory card 30 to be grasped.

For this reason, you may have to turn the device upside down or grope around to remove the memory card 30.
There is no need to search for the operating end 3 of the memory card 30.
You can remove it by touching 2 and pulling it out to the right or left. The same goes for when wearing it, and the memory can be adjusted by eye.
The approximate position where the card 30 should be attached is known, and since the guide 18 is also provided, the card 30 can be attached easily. In this way, the memory card 30 can be quickly replaced without any major interruption during operation of the portable computer 1o, making it extremely easy to use.

〔Effect of the invention〕

According to the present invention, the following effects can be obtained.

(1) Since external storage cards can be easily replaced, the operability of portable business equipment is greatly improved.

(2) External storage cards can be effectively installed on the back of portable business equipment, maximizing the number of cards that can be installed.
