2. Description of the Related Art A memory card is a kind of PC card, and is used for an external storage medium of a personal computer, an additional memory, etc., such as a database of an electronic organizer, and the demand and the field of use thereof have expanded dramatically in recent years. doing.

[0003] There are a contact type and a non-contact type as coupling means of the input / output unit of the memory card and the card using terminal. The contact type coupling means exchanges a signal by inserting a pin into a jack, and the one which exchanges a signal using about 68 pins can transfer 8-bit or 16-bit parallel data.・ The merit is that writing can be performed at high speed, but on the other hand, the pins and jacks for exchanging signals are exposed from the connector, which results in poor contact due to contamination and reduced insertion / removal resistance due to downsizing of pins. There is a problem that such troubles are likely to occur. On the other hand, the non-contact type coupling means does not have the above-mentioned trouble because the conductor is not exposed,
Particularly, since it is advantageous to use it in a dirty environment, it has been put to practical use in various fields. As non-contact type coupling means, those using electromagnetic coupling, those using optical coupling, and those using radio wave coupling have been proposed.
At present, those utilizing electromagnetic coupling in consideration of cost, power consumption and the like are most practically used.

Meanwhile, in a non-contact memory card provided with a multi-channel non-contact type coupling means, the number of channels is increased to improve the function of the non-contact memory card, or individual non-contact type memory cards are used. To increase the size of the coupling means as much as possible so as to handle a signal of a size that is unlikely to cause a communication error, or to provide a sufficient space between adjacent non-contact type coupling means so that adjacent non-contact type coupling means As shown in FIG. 11, a multi-channel non-contact type coupling means is provided between the front side (the end side on the insertion side of the card-using terminal) and either one of the left and right sides, as shown in FIG. A system in which 102 and 103 are arranged in a distributed manner has been proposed. This multi-channel contactless memory card 100 has a card slot 2 as shown in FIG.
Non-contact type coupling means 202 and non-contact type coupling means 1 which are respectively coupled to predetermined portions in
It is mounted on the card use terminal 200 provided with the non-contact type coupling means 203 coupled to the terminal 03 and used for use.

[0005] In a contactless memory card system for supplying power and / or transmitting / receiving a signal through a contactless coupling means, it is necessary to prevent a reduction in signal level and signal interference to achieve good communication. Means are required to strictly control the planar position and gap spacing of each corresponding non-contact coupling means. Therefore, the non-contact type coupling means 10 is attached to the front side of the base 101 and one of the left and right sides.
In the system using the multi-channel non-contact memory card 100 in which the non-contact type memory units 2 and 103 are distributed, the non-contact type coupling means 102 and 103 are connected to the card use terminal 200, respectively.
Positioning and gap adjusting means for accurately abutting the non-contact type coupling means 202 and 203 provided on the side are required.

Conventionally, as such positioning and gap adjusting means, for example, as shown in FIG. 12, the base 101 is attached to the side of the card slot 201 where the non-contact type coupling means 203 is not provided. And a second spring member 205 for pressing the base body 101 against the lower surface of the card slot 201 is provided on the upper surface of the card slot 201. I have.

According to the positioning and gap adjusting means, the non-contact memory card 10 is inserted into the card slot 201.
In the process of inserting the first spring member 204, the first spring member 204
Is pressed to the base 101 with respect to the card slot 201.
Is restricted in the left-right direction, and the second
Of the base member 101 with respect to the card slot 201 is regulated. Further, the non-contact type coupling means 1 provided on the front side of the base 101
When the non-contact memory card 100 is inserted into the card slot 201 to a position where the non-contact memory card 02 contacts the non-contact type coupling means 202 provided on the front side of the card slot 201, the first and second spring members 204 and 205 The frictional force acting between the substrate 101 and the wall surface of the card slot 201 and the frictional force acting between the substrate 101
Since 1 is held, the position of the base 101 in the front-rear direction with respect to the card slot 201 is also restricted. Therefore, the non-contact type coupling means 102 and 103 provided in the non-contact memory card 100 and the non-contact type coupling means 202 and 203 provided in the card slot 201 are strictly opposed to each other with respect to the plane position and the gap interval. Can be.

At this stage, a contact-type coupling means is provided at the end of the card slot, and a memory card (PC card) provided with the contact-type coupling means on the front side of the base is mounted for information processing. Card-using terminals that perform the following are widely used. For this reason, in order to enable the non-contact memory card 100 to be mounted on the contact-type card using terminal and to effectively use the contact-type card using terminal, the applicant of the present application has previously described the card slot 301 as shown in FIG. The contact-type coupling means 401 coupled to the contact-type coupling means 302 provided therein and the non-contact-type coupling means 402 and 403 coupled to the non-contact-type coupling means 102 and 103 provided in the non-contact memory card 100. (Japanese Patent Application No. 8-701) proposes a system in which an adapter device 400 having the same is interposed between the non-contact memory card 100 and the card use terminal 300.
No. 98).

In such a system, the non-contact type coupling means 102, 1 provided in the non-contact memory card 100 are also provided.
03 and the non-contact type coupling means 402 and 403 provided in the adapter device 400 are strictly opposed to each other with respect to the plane position and the gap interval to prevent a communication error.
Requires some positioning and gap adjustment means.
Conventionally, the positioning and gap adjusting means to be set between the non-contact memory card 100 and the adapter device 400 also serve as the non-contact memory card 100.
There has been proposed a positioning and gap adjusting unit set between the terminal and the card using terminal 200.

[0010]

However, the positioning and gap adjusting means between the non-contact type coupling means which have been conventionally proposed include the first spring member 204 and the second spring member 2.
05, which requires a large number of parts, increases the cost of the card use terminal 200 or the adapter device 400, and requires a large space for setting the first and second spring members 204, 205. Usage terminal 200
Alternatively, there is a problem that the adapter device 400 becomes large.

The positioning and gap adjusting means comprises the first and second spring members 204 and 205 and the base 10.
1 and the frictional force acting between the substrate 101 and the wall surface of the card slot 201 holds the substrate 101 only.
Card use terminal 200 or adapter device 40 on which
If an improper external force, such as vibration, acts on 0, the non-contact coupling means tends to deviate from a favorable facing state, and there is a problem that a communication error tends to occur.

If the spring members 204 and 205 are made of a material having a high elastic force, the disadvantage that the vibration resistance is weak can be avoided. Omission is also possible.
However, it is not preferable to use a spring member having a high elastic force, since the feeling of attaching and detaching the non-contact memory card 100 is deteriorated and the non-contact memory card 100 may be damaged or deformed.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned deficiencies of the prior art, and has as its object to provide a planar position and a gap interval of non-contact coupling means distributed on two orthogonal sides. To provide a non-contact memory card, a card-using terminal, and an adapter device, which can strictly restrict the other non-contact coupling means coupled thereto, and can realize highly reliable multi-channel communication. is there.

[0014]

One card pressing means for urging the card toward the two sides where the non-contact type coupling means is provided is provided.

As the notch to be formed in the non-contact memory card, a V-shaped notch can be formed on the side of the base where the non-contact type coupling means is not provided, and the non-contact memory is engaged with the notch. The card pressing means for pressing the card in a required direction may include an elastic member partially provided with a pressing portion of the non-contact memory card.

When the non-contact memory card constructed as described above is inserted in a predetermined direction to a predetermined position into the card-using terminal or the adapter device configured as described above, it is formed on the base of the non-contact memory card.

As described above, according to the present invention, two sets of non-contact type coupling means disposed on two orthogonal sides can be positioned with high accuracy by one card pressing means. Alternatively, the configuration of the adapter device can be simplified. Also, since the card pressing means provided in the card use terminal or the adapter device is mechanically engaged with the inclined side of the notch formed in the non-contact memory card, when the non-contact memory card is held only by frictional force.

The contactless memory card system of the present embodiment is characterized by comprising a contactless memory card and a card using terminal. 1 is a bottom view showing a state where a lower surface plate of a card slot provided in a card using terminal is removed, FIG. 2 is a bottom view showing a state where a non-contact memory card is partially inserted into the card slot of FIG. 1,
FIG. 3 is a bottom view showing a state in which the non-contact memory card is completely inserted into the card slot of FIG. 1, and FIG.
It is a fragmentary sectional view.

As shown in FIGS. 1 and 4, the card slot 1 of the present embodiment comprises a non-contact memory card having a frame-shaped portion 2, a top plate 3 and a bottom plate 4 formed in a U-shape in plan view. It is formed in a box shape that can be inserted, and is electrically connected to a non-contact type coupling means provided on a non-contact type memory card at an end of the frame-shaped portion 2 and a right side in the drawing to supply power. And / or non-contact coupling means for transmitting and receiving signals
Is provided. The frame-shaped portion 2 and the upper surface plate 3 or the lower surface plate 4 can be formed separately or can be formed integrally. Further, as the non-contact type coupling means 5 and 6, those using electromagnetic coupling, those using optical coupling, those using radio wave coupling, and the like can be used. When the non-contact type coupling means is used, a non-contact connector in which a plurality of non-contact type coupling means are integrally molded with resin can be used.

A rectangular notch 7 is formed inside a side of the frame 2 that does not have the non-contact type connecting means 6, and a non-contact memory card is connected to the non-contact type memory card inside the notch 7. One card pressing means 8 for urging the setting sections of the means 5 and 6 is provided. The card pressing means 8 includes a torsion spring 9 and a mountain-shaped pressing portion 10 attached to one side of the spring 9.
By being fixed inside, the inclined surface 10 of the pressing portion 10
a, 10b are set to protrude from the notch 7 into the insertion path of the non-contact memory card.

A semi-circular notch 11 is formed on the card insertion opening side of the upper surface plate 3 to facilitate removal of the non-contact memory card inserted into the card slot 1.

On the other hand, the contactless memory card 21 is shown in FIGS.
As shown in FIG. 4, the non-contact provided in the card slot 1 between the front side (the end side on the insertion side into the card slot 1) of the card-shaped base 22 and the right side in the drawing. Non-contact coupling means 23 and 24 are provided which are electrically coupled to the coupling means 5 and 6 to receive power and / or transmit and receive signals. Further, the card slot 1 is provided on the side of the base 22 on which the non-contact type coupling means 24 is not provided.
A V-shaped notch 25 for engaging the pressing portion 10 of the card pressing means 8 provided therein is formed. Of course, the non-contact type coupling means 23, 24 mounted on the non-contact memory card 21 are arranged in the same positional relationship as the non-contact type coupling means 5, 6 provided in the card slot 1. When the non-contact memory card 21 is inserted to a predetermined position in the card slot 1, the non-contact contact coupling means 5 and 23 and 6 and 24 face each other. When the non-contact memory card 21 is inserted to a predetermined position in the card slot 1, the V-shaped notch 25, as shown in FIG.
a is formed at a position where it engages with the inclined side 25a.

Hereinafter, the operation of the contactless memory card system according to this embodiment will be described.

When the non-contact memory card 21 is inserted from the card slot of the card slot 1 in a predetermined direction,
The left corner of the non-contact memory card 21 contacts the inclined surface 10b of the pressing unit 10. From this state, contactless memory card 2
1 is further inserted, the torsion spring 9 is elastically deformed by the insertion force of the non-contact memory card 21, and the pressing portion 10
Is stored in the notch 7. When the left corner of the non-contact memory card 21 gets over the inclined surface 10b of the pressing portion 10, FIG.
As shown in FIG. 3, the top of the pressing portion 10 is in contact with the side of the base 22 so that the contactless memory card 2
1 is performed in the left-right direction. When the non-contact memory card 21 is further inserted from this state, the non-contact coupling means 5 provided at the end of the card slot 1 and the non-contact coupling means 23 provided on the front side of the non-contact memory card 21 are connected. At the stage of the butting, the inclined side 2 of the notch 25 formed in the non-contact memory card 21 as shown in FIG.
The inclined surface 10a of the pressing portion 10 is engaged with 5a. Notch 25
When the inclined surface 10a of the pressing portion 10 is engaged with the inclined side 25a of the non-contact type, the component force Fa in the direction of bringing the non-contact type coupling means 5 and 23 into close contact with the non-contact type memory card 21 as shown in FIG. The component force Fb in the direction of bringing the coupling means 6 and 24 into close contact with each other acts to hold the non-contact memory card 21 in the card slot 1. The removal of the non-contact memory card 21 from the card slot 1 can be performed by inserting a finger into the semicircular notch 11 formed on the upper surface plate 3, grasping the non-contact memory card 21, and pulling the card forward.

As described above, the contactless memory card system of the present embodiment has the notch 25 formed in the contactless memory card 21.
By engaging the inclined surface 10a of the pressing portion 10 provided in the card slot 1 with the inclined side 25a of the card slot 1, the component force Fa in the direction of bringing the non-contact type coupling means 5 and 23 into close contact with the non-contact memory card 21 is not affected. Since the component force Fb in the direction of bringing the contact-type coupling means 6 and 24 into close contact is applied, only by inserting the non-contact memory card 21 to a predetermined position in the card slot 1, two sets of non-contact-type coupling are automatically performed. Means 5 and 23
, 6 and 24 can be accurately faced to each other with respect to the surface direction position and the gap interval.
1 can be sufficiently supplied and communication errors can be prevented. Further, since the non-contact memory card 21 is held by mechanically engaging the base 22 and the pressing portion 10, the non-contact memory card is held as compared with the conventional non-contact memory card system which holds the non-contact memory card only by frictional force. The contact memory card 21 can be stably held, and displacement or detachment of the non-contact type coupling means due to vibration or the like can be prevented. In addition, since the connection of each non-contact type coupling means can be stably maintained without increasing the elastic force of the spring 9, the feeling of attaching and detaching the non-contact memory card 21 to and from the card slot 1 is deteriorated, and the base 22 is damaged. Can be eliminated. Furthermore, the positioning and holding of the two sets of non-contact type coupling means 5 and 23 and 6 and 24 can be stably performed only by providing one card pressing means 10, so that the configuration of the card using terminal or the adapter device is simplified. Can be

In the embodiment, the torsion spring 9 is used as an elastic member constituting the card pressing means 8.
However, the gist of the present invention is not limited to this, and an appropriate elastic member can be used as needed. FIG. 5 illustrates a case where a coil spring 31 is used as the elastic member, and FIG. 6 illustrates a case where a plate spring or a wire spring 32 having a mountain-shaped pressing portion 32a is formed. .

In the above embodiment, a semicircular notch 11 is formed in the upper plate 3 of the card slot 1 so that the non-contact memory card 21 can be manually removed from the card slot 1. As shown in FIG. 7, the card slot may be provided with an ejection mechanism 41 for the non-contact memory card 21 so that the non-contact memory card 21 can be mechanically removed from the card slot 1. In the example of FIG. 7, an eject mechanism 41 is pivotally attached to an operation member 42 movably provided in the direction of insertion of the non-contact memory card 21 and a shaft 43, and one end 44 a is connected to the operation member 42 by a pin. And the other end 44b
Member 4 is in contact with the front side of non-contact memory card 21
And 4.

Before the non-contact memory card 21 is inserted, the ejecting mechanism 41 of the present embodiment has the other end 44b of the revolving member 44 inserted into the non-contact memory card of the card slot 1 as shown by a solid line in FIG. The operation member 42 protrudes into the path and is pushed into the card slot 1.
When the non-contact memory card 21 is inserted into the card slot 1, the turning force causes the turning member 44 to turn clockwise due to the insertion force, and the tip of the operating member 42 projects from the card slot 1 as shown by a chain line in FIG. . In a state where the non-contact type coupling means 5 and 6 provided in the card slot 1 and the non-contact type coupling means 23 and 24 provided in the non-contact memory card 21 are coupled, the distal end of the operating member 42 is connected to the card slot 1. When pushed into the card slot 1, the turning member 44 turns counterclockwise due to the pressing force, and the non-contact memory card 21 is ejected from the card slot 1.

The ejection mechanism 41 of the present embodiment ejects the non-contact memory card 21 manually. However, the ejection mechanism 41 may be configured to eject the non-contact memory card 21 electrically.

Further, in the above embodiment, the card slot 1 is constituted by the frame portion 2, the upper plate 3 and the lower plate 4, but as shown in FIG.
Thus, a card slot can be formed, and the top plate 3 can be omitted. In the non-contact memory card system of this example, a concave groove 51 is formed on the side surface of the non-contact memory card 21, and a protrusion 52 engageable with the concave groove 51 is formed on a corresponding portion of the card slot 1. In addition, the vertical movement of the non-contact memory card 21 with respect to the card slot 1 is restricted.

The adapter device 71 has a body having a substantially U-shape in plan view, and a recess surrounded by a main body 72 and two guide rails 73 and 74 has an insertion portion for the non-contact memory card 91. It has become. Non-contact type connecting means 75 and 76 for electrically connecting the non-contact type connecting means 23 and 24 provided on the non-contact memory card 91 in a non-contact manner are provided at the end of the insertion portion and the inner surface of the guide rail 73. And a rectangular notch 77 is formed on the inner surface of the other guide rail 74 where the non-contact type coupling means 76 is not provided, and the non-contact type memory card 91 is provided inside the notch 77 with the non-contact type coupling means. One card pressing means 78 is provided to urge the setting portions 23 and 24. The card pressing means 78 is the first embodiment (see FIGS. 1 to 8).

On the outer surface of the adapter device 71, an engaging portion 80 for inserting the adapter device 71 into a card guide portion 63 provided in the socket 61 is provided. On the inner surfaces of the guide rails 73 and 74, A guide groove 81 for guiding the non-contact memory card 91 is formed.

The non-contact memory card 91 is formed in the same size as the non-contact memory card 21 shown in the first embodiment, except that the card size is formed to a size that can be mounted on the adapter device 71. Therefore, the contactless memory card 9
