Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a card @l-enjoy device having electronic functions. More specifically, the present invention relates to a device for attaching and detaching a card incorporating an integrated circuit a (hereinafter referred to as an IC).

With the recent development of IC technology, it has become possible to realize large-scale ICs on small chips, and a wide variety of products with advanced functions have been developed, and their uses have further expanded.

For example, read-only memory (R0M) i' in which programs such as microprocessors are written, random access
Cards with memory (RAM) embedded in thin cards have also come to be manufactured.

Furthermore, electronic devices incorporating microprocessors and other devices have become smaller, and many are now pocket-sized.
There is a growing desire to use cards with integrated ICs and the like in these devices.

To give an example of its use, so-called credit cards and cash cards, which are often used in the financial field, tend to be converted to ICs, and devices that use such electronic cards are also becoming part of the so-called Pogrid Products. It's too needed.

[Prior art 1] When using such an electronic card, connection points 1 and 1 printed circuit board (hereinafter referred to as PCB) between the card and electronic equipment are used.
It is abbreviated as ), but since the handling of electronic cards is usually very rough, the edges are particularly prone to damage and are unreliable. In addition, many leads had to be drawn out from many terminals of the IC to the edges of the card, which was not always easy for the production department and caused an increase in price.

In order to solve this problem, the terminals are not pulled out to the edge of the card, but rather the terminals of the IC buried in the card itself or near the terminals ('g) are used as terminals to connect to electronic equipment.

When such an electronic card, which has terminals inside, is inserted into or removed from an electronic device, the contact pins of the electronic device and the terminals of the electronic card are rubbed against each other, and the contact pins are damaged, for example. It was not possible to achieve reliability such as 1 million attachment/detachment cycles.

: Also, in order to prevent the contact pins of the electronic device from rubbing against the terminals of the electronic card, some devices retract the contact pins before inserting the electronic card, and then push out the contact pins to make contact. However, the 4M machine was complicated, had a large shape, and had poor operability, leading to increased costs. Furthermore, in the case of electronic cards in which many terminals are arranged at fine pitches, there is a problem in that the reliability of contact is also lacking because it is not possible to accurately position the electronic card when it is mounted.

Therefore, the applicant of the present application filed U.S. Pat. No. 60-055007 in order to solve the problems of the prior art.

This will be shown and explained below in FIG.

FIG. 5 is a sectional view showing the electronic card attachment/detachment device attached to the shell 111.
Electronic equipment" (required. Here, 10 is the main body of the electronic equipment, 11 is an operation panel, 12 is, for example, a liquid crystal C display, 13 is a key for inputting data and operation, 14 is a bottom plate, 15 20 is a card holder for holding the electronic cars 1-16; 20 is a card latch for wrapping the electronic car 1-16 in a predetermined position when it is inserted; 21 is a part of the card latch; , electronic card 16
A card kite with a step on the back for kiting,
22 is a reference surface which is the back surface of the card kite which is the standard for the position when the electronic card 16 is latched; 23 is a reference surface that allows the card latch 20 to move by a small angle;
A card latch shaft 26 serves as an axis for allowing the ID 21 to move up and down; 26 is a plurality of contact terminals attached to a part of the card latch 20 to make contact with the terminals of the electronic card; 2°7 is a contact terminal 26; 28 is a terminal hole drilled in the card holder 15 through which the terminal 26 is passed, and 31 is a flexible printed circuit board (PCB) for pulling out the signal line from the card holder 20, for example, a flexible printed circuit board (PCB) for drawing out the signal line from the card holder 15. For example, a spiral spring 33 is a pushing means for pressing the electronic card 16 against the reference surface 22 and pushing out the electronic card 16 when the electronic card 16 is taken out.For example, a leaf spring 35 is Glue jet key leg 36 for pushing down the card latch 20 when taking out the electronic card 16
is a reject key with

FIG. 5(a) shows the electronic card 16 inserted and latched, and FIG. 5(b) shows the electronic card 16 about to be inserted.

In FIG. 5(b), when the electronic card 16 hits the nine-tooth guide 21 to insert the electronic card 16, the card latch 20 is pushed down in the direction shown by the arrow 41, and the electronic card 16 is placed above the card holder 15. It is inserted by slipping. The leading edge of the electronic card 16 presses against the leaf spring 33, and when the rear end of the electronic card 16 passes over the back of the card kite 21, it falls into the step on the back of the card guide 21, and due to the pressing force of the temporary spring 33, the electronic card 16 is pushed. The rear end is pressed against the reference surface 22. This allows the electronic card 16 to be accurately aligned.

FIG. 6 is a plan view of the present invention with the panel 11 in FIG. 5 removed. Here, the electronic card 16 is shown by a dashed line, and since its tip is always pressed by the root spring 33, it is necessary to press the reject key 35 in the direction of the arrow 40 shown in FIG. 5(a). If the reject key leg 36 or the card latch 20 is depressed, the electronic card 16 is ejected. This allows the electronic card to be easily taken out. The pressing force of the leaf spring 33 is, for example, about 1000, which does not cause an excessive reaction when inserting the electronic card 16.

In FIG. 6, the card holder 15 has a wide opening (opening) near the card guide 21, as shown at 158, to facilitate the introduction of the electronic card 16. Also, part of the card guide 21 (2
1a> and a part (15b) of the card holder 15 have a cutout shape to improve operability.
It makes it easy to put on and take off. In FIG. 6, 24 is a bearing of the card latch shaft 23 fixed to the bottom plate 14.

7 shows a sectional view seen from the right side of FIG. 5, and FIG. 8 shows the card latch 20.

For example, when the electronic card 16 is inserted, the contact terminal 2G (FIGS. 5 to 8) attached to the card latch 20 made of plastic is placed below the surface of the card holder 15 as shown in FIG. 5(b). It's been pushed down,
The electronic card 16 is not rubbed, the electronic card 16 is not scratched, and the contact terminals 26 are not damaged either. When the electronic card 16 is latched, as shown in FIG. 5(a).
Accordingly, the contact terminals 26 are pushed up and come into contact with the terminals of the electronic card 16. The thickness of the electronic card 16 is, for example, 0.76 mm, and the terminal portion of the electronic card 16 is recessed by about 0.2 mm from its surroundings. Therefore, by lifting the contact terminals and making contact after the position of the electronic card 16 is determined, it is possible to make reliable contact without damaging the terminal portion of the electronic card 16. In the above description, the force for pushing up the card latch 20 is provided by the spring 31, which is a spiral spring, but this may be done as shown in FIG. 9 or 10.

In Fig. 9, 3ε3 is a U-shaped spring as shown in (i)), and the width of the 0 character is W, and (a)
It is attached between the bottom plate 14 and the card latch 20 as shown in FIG. The U-shaped spring 38 is about to become wider than its width ~■, pushing the card latch 20 upward.

Conversely, when the card latch 20 is pushed down in the direction shown by the arrow 42, the width of the U-shaped spring 38 becomes smaller than W, so
When the force to push down is gone, push up the card latch 20.

In FIG. 10, 39 is a spring 21, which is installed around the shaft between the card latch 23 and the bearing 24.
This ensures that the card latch 20 is always pushed upward.

In the following explanation, the reject key 35 is placed at 19 so as to press down on the card guide 21, but since it is used to press down on the card latch 20, it may be placed at any other position.

In addition, in FIGS. 5 to 7, an electronic circuit is incorporated inside the main body 10, but it is not shown because it has no direct relevance to the present invention.

[Problem to be solved by the invention 1 The prior art described in FIGS. 5 to 10 solves many problems, but it has the following problems.

In order to take out the electronic card, a manual reject key is used and pushed down to push down the card latch, and the electronic car 1- is pushed out by the leaf spring.

However, when you press down on the RigiTri1~ key, the electronic card is immediately pushed out.
The reject key may be pressed down while writing to or reading from the ROM or RAM built into ~, or it may be pressed down by mistake, which may cause the contents of the ROM or RAM to become incorrect. There was a problem in that there was a possibility of using -C (or being destroyed).

Furthermore, since this ejection of the electronic card is done by temporary springs, it is necessary to keep the stroke distance of these four anti-springs to a sufficient distance. The spring is strained. Because of this, I had the problem of getting tired as early as 1i11.

[Means for Solving Problems] The present invention has been made to solve the problems of the prior art as described above. , the first coil spring connected between the first receptacle and the bottom plate that forms part of the main body is stretched out, and when the electronic card is inserted into the electronic card and its rear end passes the card guide, the electronic Car 1-
falls into the step on the back of the card guard and is latched.

There is a second reject plate that slides parallel to the first reject plate, a second coil spring is connected between the first reject plate and the second reject plate, and the tip of the second reject plate is arranged at a small angle. There is a stopper rotatable in the range of , which stops following the pushing movement of either the second reject plate or the first reject plate, so that the second coil spring remains stretched.

This stopper can be rotated by a small angle using a solenoid. This second reject plate is provided with a gluing arm.

A part of the ji-drudge is provided with a reject taper that allows the card latch to be lowered by the movement of this reject arm.

[Operation] When the electronic card is inserted and the first rejiku i temporary is pushed in, the first coil spring and the second coil spring are stretched out and the electronic card is latched. Electronic car i~
When the ROM or RAM is not occupied or read out, a current is momentarily applied to the solenoid, causing the second recycler to rotate in a small angle, and the second resetter to move, which had temporarily stopped its movement. 1 ~ From the tip of the board, the 2nd rejiku 1 ~ board is pushed in by the tl and the 2nd coil spring, and at the same time, the 2nd rejiku 1 is pushed in. 1- Move the tab and rotate the card latch by a small angle to lower the card guy i~, and push out the electronic card with the force of the first coil spring.

As a result, the electronic card 1- no longer flies out during fortune reading of the electronic card 1, and the contents of the electronic card are no longer damaged or destroyed. Solenoid 1- is used to move and tighten the stopper (it only needs to have the force to do so, and it only needs to be small because suction over a short distance is sufficient, and only a small amount of electric power is required. The electronic card is pushed out by the first coil. In order to achieve this, a sufficient extrusion distance is provided so that the product does not become fatigued for long-term use.

[Example] An example of the present invention is shown in Fig. 1, Fig. 2, Fig. 3A, and Fig. 3B.

When the electronic card 16 is inserted, its tip hits the card kite 21, pushes up the card wrap 20A, and slides on the surface of the card holder 150, causing the lowered contact terminals 26 to contact the abutment portion 57 without rubbing. They hit each other (Fig. 1(b), Fig. 3A).

When the electronic card 16 is pushed roughly in the direction shown by the arrow 92 in FIG. 3A(b), the abutting portion 57
) direction. Thereby, the coil spring 59
is stretched, and the second reshiek i~ plate is also pulled by the coil spring 69, but the stopper 71 or the stopper 71 stops its movement.
Due to the concave shape, the coil spring 9 is stretched to the extent that it cannot be moved.

Then, when the electronic card 16 goes over the rear end of the electronic card 16 or the two card guides and falls into the step on the back side, the card wraps - 20.
, A are pushed up by the pushing force of the spring 31, the contact terminals 26 come into contact with the electronic card 16, and the electronic card 16 is wrapped (FIG. 1(a) and FIG. 3B).

This wrap - 4 servings (LL, 2 R-IT) Due to the force of the panel 59, the electronic card 16 is pushed by the abutment part 57 in the direction of the arrow 97 (FIG. 3B (b)), so that the electronic card Since the rear end portion of the card kite 21 is pressed against the reference surface 22, which is the back surface of the card kite 21, and placed at an accurate position, the contact terminal 26 can be brought into contact with extremely high precision.

In the state shown in FIG. 1(a) and FIG. 3B, when current is momentarily applied to the solenoid 77, the solenoid 7
7 operates to move the wire 74 to the arrow 91 (Fig. 3B (a))
The stopper 71 is slightly rotated about the stopper shaft 74 (FIG. 4B) by overcoming the force of the tension coil spring 79 in the direction indicated by , and is removed from the second reject plate tip 68.

Then, the second reject plate 61, which was being pulled by the coil spring 69, rapidly moves in the direction shown by the arrow 93 (FIG. 3B (a), FIG. 4A). Then, the reject arm 6
7 moves in the direction shown by arrow 93 and pushes down the reject taper 82 in the direction shown by arrow 95 (FIG. 4A).
The card latch 2OA rotates by a small angle so that the card kite 21 is positioned below the surface of the force-hold holder 15, so that the coil spring 59 pushes out the electronic card 16 via the abutting portion 57. The state returns to the state shown in FIG. 1(b) and FIG. 3A. Here, the electronic card 16 pops out 29.4. t
The chi can be set by the length of one hole 52.53, 62.63.
