2. Description of the Related Art Compact Flash (registered trademark) cards are non-volatile, and therefore, for example, system BIOS.
It is often used as a storage medium for S information, and when it is used for such a purpose, it is mounted in a state where it cannot be easily removed by a general user.

On the other hand, when updating the system or the like, it is necessary to replace these compact flash cards, and as a mounting structure that can meet this demand, for example, the one shown in FIG. 7 is used.

That is, in this conventional example, the housing B of the electronic device can be divided into upper and lower parts, and the card insertion portion 4 of the compact flash card 1 formed in the lower cover B1 is opened in the boundary wall with the upper cover. The pull-out tape 6 previously attached to the upper surface of the compact flash card 1 is pulled out.

To remove the compact flash card 1,
First, after disconnecting the upper and lower covers B1 and B2 of the case B, the pull-out tape 6 is pulled to the outside of the case B (in the direction of the arrow in FIG. 7), and the compact flash card 1
Is pulled out from the card insertion portion 4.

[0006]

However, in the above-mentioned prior art, there is a problem that it takes time because the housing B needs to be disassembled when the compact flash card 1 is replaced.

The present invention has been made to solve the above drawbacks, and an object of the present invention is to provide a drawing tool for a compact flash card that facilitates replacement work.

[0008]

A compact flash card 1 is provided with a step portion 1a at a side edge facing a connection side to a connector 7, and a general mounting method, that is, a connection side to the connector 7 is provided. When it is inserted into the housing B by pushing it in a posture in which the step is at the top, the step portion 1a is on the front side, that is,
It will be located in the vicinity of the outer side wall of the housing B.

The present invention facilitates the withdrawal of the compact flash card 1 from the housing B by utilizing the step portion 1a provided in the compact flash card 1. After the locking piece 2 is locked to the step portion 1a so that the compact flash card 1 is clamped by the locking piece 2 and the clamping piece 3 of the inserted extraction tool A, it is easy to pull the extraction tool A. It can be carried out.

If the locking piece 2 and the sandwiching piece 3 are formed in a bifurcated shape, the bifurcated engagement is formed on the wall surface of the card insertion portion 4 on the side of the housing B that houses the compact flash card 1. These can be inserted only by forming the insertion groove 5 through which the stopper 2 and the like can be inserted. Therefore, the remaining wall surface of the card insertion portion 4 can be used as a guide surface for guiding the front and back surfaces of the compact flash card 1 or a regulation surface for preventing wobbling, which improves the mounting workability and is compact. The flash card 1 can be prevented from wobbling and contact failure.

FIG. 1 shows an embodiment of the present invention configured as a handheld computer. The handheld computer includes a display unit 8 and a key input unit 9 and can be used outdoors, and includes a printer 10 for printing out collected information, a communication unit (not shown) with a host computer, and the like. .

FIG. 5 shows a tool for pulling out the compact flash card 1 mounted in the housing B. The extraction tool is a tool for extracting the compact flash card 1 from the inside of the housing B by using the step portion 1a formed on one side edge of the compact flash card 1 having a substantially rectangular package shape. The locking piece forming plate A1 and the sandwiching piece forming plate A2 that are formed are stacked and fixed vertically.

A locking piece forming plate A1 and a holding piece forming plate A2
Are provided with a grip portion 11 at one end, and are joined at the grip portion 11. The gripping portion 1 is provided on the locking piece forming plate A1.
A holding piece 2 that branches from 1 into a bifurcated shape is formed, and a holding piece 3 that branches into a bifurcated shape from the gripping portion 11 is formed on the holding piece forming plate material A2. The holding piece 3 is bent in the plate thickness direction with respect to the grip portion 11, and in the state where the holding piece forming plate material A2 and the locking piece forming plate material A1 are joined at the holding portion 11, the holding piece 2 and the holding piece are sandwiched. 3 is opposed to the compact flash card 1 with a space slightly smaller than the thickness of the compact flash card 1, and a locking bent portion 2a bent toward the holding piece 3 is formed at the free end of the locking piece 2. To be done.
As will be described later, the spacing (W2) between the locking pieces 2 and 2 and the spacing (W3) between the holding pieces 3 and 3 are different so as to regulate the insertion posture of the housing B into the card insertion portion 4. Is formed as.

2 to 4 show the case B of the handheld computer. In order to accommodate the compact flash card 1 in the housing B, a card insertion portion 4 that opens to the side is opened on the side wall of the housing B, and the compact flash card 1 is mounted in the innermost portion thereof. The connector 7 for is arranged. In FIG. 4, 12 is the connector 7
2 shows a mounting board on which is mounted.

The card insertion part 4 is closed by a lid 13 so that the compact flash card 1 mounted in the card insertion part 4 is not accidentally removed. As shown in FIG. 3, the lid body 13 is a piece of synthetic resin having locking hook portions 13b on both side edges of the main body 13a, and the locking hook portions 13b are locked to the side wall portions of the card insertion portion 4. Then, it is attached to the case B.

On the other hand, the card insertion portion 4 has an insertion groove 5 on its upper and lower surfaces, through which a locking piece 2 and a holding piece 3 of a pulling tool A, which will be described later, can be inserted. Corresponding to the bifurcation of the locking piece 2 and the sandwiching piece 3, these insertion grooves 5 are provided in two recesses on the upper and lower surfaces of the card insertion portion 4, respectively, and the step portion 1a is lowered downward. In this embodiment designed to mount the compact flash card 1 toward, the upper surface (ceiling surface) side corresponds to the sandwiching piece 3 and the lower surface (bottom wall surface) side corresponds to the locking piece 2. The distance between the upper surface side insertion grooves 5 and 5 and the distance between the lower surface side insertion grooves 5 and 5 are the distance (W3) between the holding pieces 3 and 3 of the extraction tool A and the distance between the locking pieces 2 and 2. Interval (W
2) is different from the above, and the insertion of the extraction tool A in the upside down posture is prohibited. Further, the insertion groove 5 on the upper surface side is provided with the lid 13 so that the card insertion portion 4
It is provided at a position that opens to the outer peripheral wall of the housing B even in the closed state.

Therefore, in this embodiment, as shown in FIG.
As shown in (b) and FIG. 4 (a), the compact flash card 1 is mounted, and the lid 13 is used to insert the card insertion portion 4
In order to replace the compact flash card 1 from the closed state, first insert the holding piece 3 of the extraction tool A into the insertion groove 5 opened on the outer wall surface of the housing B, and pry the extraction tool A. Unlock the locking hook,
The lid 13 is removed from the housing B. After that, as shown in FIG. 2A, the sandwiching piece 3 and the locking piece 2 are inserted into the two insertion grooves 5 that appear above and below the end face of the compact flash card 1 on the insertion rear end side. As described above, since the space (W3) between the sandwiching pieces 3 and the space (W2) between the locking pieces 2 and the space between the insertion grooves 5 corresponding to these are different, the upper limit inversion posture It cannot be inserted.

When the extraction tool A is inserted in such a posture that it can be inserted into the insertion groove 5, the holding piece 3 moves along the ceiling surface of the compact flash card 1 while elastically deforming the holding piece 3, and eventually the locking piece. When 2 gets over the step 1a,
The elastically restoring force causes the locking bent portion 2a of the locking piece 2 to fall into the step portion 1a and be formed on the step portion 1a (see FIG. 6). In this state, the compact flash card 1 is sandwiched by the sandwiching piece 3 and the locking piece 2, and the unlocking of the locking bent portion 2a is restricted, and then the pull-out tool A is pulled out to the front side. Then, the compact flash card 1 is pulled out following the movement of the pulling tool A.
