DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC card ejection device mainly used in a portable information processing device such as an electronic organizer in which an IC card is detachably mounted.

[0002]

2. Description of the Related Art FIGS. 13 and 14 show a conventional IC card ejection device. 13A and 13B are a bottom view and a side view of an IC card mounted state, and FIGS. 14A and 14B are ICs.
It is the bottom view and side view of the card ejection state.

In FIGS. 13A and 13B, an input / output terminal of an IC card 100 is connected to a connector 4 while being mounted on a card slide plate 2. The connector 4 is provided on the main body chassis 6. When the IC card 100 is ejected, the ejection lever 8 pivotally attached to the main body chassis 6 is pulled in the arrow X direction against the return spring 10. Then, the action point 8a at the intermediate portion of the ejection lever 8 presses the bent piece 2a on the near side of the card slide plate 2, and moves the card slide plate 2 in the direction of the arrow X. Reference numeral 8b denotes a fulcrum of the discharge lever 8, and reference numeral 8c denotes an operation unit which is a power point of the discharge lever 8. That is, the ejection lever 8 utilizes the principle of leverage.

[0004] There is also a bent piece 2b on the back side of the card slide plate 2, which is in contact with the end on the back side of the IC card 100, so that the IC card 100 moves in the X direction as the card slide plate 2 moves. 100 is also forcibly moved in the X direction, and the input / output terminal of the IC card 100 is pulled out from the connector 4. This is the state shown in FIGS. 14A and 14B. When the IC card 100 is pulled out and the operation force applied to the ejection lever 8 is released, the card slide plate 2 and the ejection lever 8 are pushed to the back side by the urging force of the return spring 10, and return to the origin position.

Although the mating resistance between the input / output terminal of the IC card 100 and the connector 4 is quite large, a relatively small operating force is required because the ejection lever 8 is a booster mechanism utilizing the principle of leverage. Thus, the input / output terminal can be pulled out from the connector 4.

[0006]

However, in order to make use of the principle of leverage, the operating portion 8c of the ejection lever 8 is located on the side portion of the apparatus main body, and the side portion has a space for reciprocating movement. Need. Since the space for the operation unit 8c and the movement of the operation unit 8c must be ensured, the use of the side surface of the device body is restricted.

[0007] For example, it is not possible to dispose an extension function section such as an extension slot on a side portion of a device body. If the extension function unit is to be arranged, it must be arranged at another location, which unnecessarily increases the size of the device body.

The present invention has been made in view of such circumstances, and has a function of extracting an IC card with a relatively small operation force, and also suppresses an increase in the size of a device body as much as possible. It is another object of the present invention to allow a side portion of the device main body to be opened for disposition of an extension function unit.

[0009]

IC card ejection apparatus according to the present invention SUMMARY OF THE INVENTION have a contact with the bent pieces on the back end of the IC card, to the far side with the insertion of the placed IC card while moving, the card slide plate to push the IC card by the movement of the front side, and holds the left and right sides of the card sliding plate, and right and left pair of slidably mounted along a slider guide of the device the body and slider, interposed between each slider and the device body, a pair of compression springs for accumulating a biasing force moves to an inner side of the card sliding plate, on the back side of the mosquito Dosuraido plate <br / > Contact Keru disposed in an intermediate position of the two compression springs, to the back side
Is arranged a locking mechanism for locking the mosquitoes Dosuraido plate in a state where the connector of the input and output terminals and the apparatus main body side is connected to the moved IC card, your Keru intermediate position between both the compression spring on the back side of the mosquito Dosuraido plate and, It has been sliding operation
And an unlocking tool to unlock state of'm Luke Dosuraido plate to lock mechanism upon, lock machine
The mechanism is to lock the card slide plate that has moved to the back side
Locks the start-up piece and locks it by sliding.
Locking state of the rising piece for locking due to the contact of the removal operation tool
And a pair of arms for releasing
That that you are characterized by.

[0010]

When the IC card is placed on the card slide plate and pushed inward, the back end of the IC card comes into contact with the bent piece of the card slide plate, and the IC card is further opposed to a pair of left and right compression springs. When pushed in, the card slide plate and the pair of left and right sliders are moved to the back side integrally with the IC card, and the urging force is accumulated in the pair of left and right compression springs accordingly.

When the integrated movement to the rear side is performed by a predetermined amount, the input / output terminals of the IC card are fitted and connected to the connector of the device main body. At that time, the lock mechanism operates. Even if the pushing operation force applied to the IC card is released, the lock mechanism overcomes the biasing force of the pair of left and right compression springs and holds the card slide plate and the pair of left and right sliders at the connector connection position.

In this locked state, the biasing force accumulated in the pair of left and right compression springs is also considerably large. Such a compression spring that accumulates an urging force as the IC card is pushed into the connector connection position has not existed in the conventional case.

A lock mechanism for maintaining the locked state by overcoming the biasing force of the pair of left and right compression springs, and a lock release operating tool for releasing the locked state by the lock mechanism are provided on both sides of the back surface of the card slide plate. It is located at an intermediate position of the compression spring. Since the unlocking operation tool is operated by the user, it must be in a state of being exposed to the outside of the apparatus body, similarly to the operation section of the discharge lever in the conventional example.

However, in the prior art, the operating portion of the ejection lever utilizing the principle of leverage is exposed on the side surface of the apparatus main body, whereas in the case of the present invention, it is exposed on the back side of the apparatus main body. Will be. The side portion of the device body is opened for disposing an extension function unit such as an extension slot.

From the state where the input / output terminal of the IC card is connected to the connector and the card slide plate is locked by the lock mechanism, the locked state is released by sliding the unlocking operation tool. Then, the urging force of the pair of left and right compression springs, which has been blocked by the lock mechanism, is developed. The mating resistance between the input / output terminal and the connector is quite large, but by expressing the biasing force accumulated in the pair of left and right compression springs, the mating resistance is overcome and the input / output terminal is pulled out of the connector. be able to.

The unlocking operation tool does not pull out.
The lock release operation tool only releases the locked state of the card slide plate by the lock mechanism for generating the urging force.

Therefore, as the unlocking operation tool,
It is not necessary to be so large and thick, and the device main body does not need to be unnecessarily increased in size, even though the unlocking operation tool is arranged on the back side of the device main body. Also,
The operating force applied to the unlocking operation tool can be small.

Finally, as shown in FIGS. 7 and 8, a helical spring H for returning to the origin is set. An intermediate helical portion of the homing helical spring H is inserted and locked in the pin 60, one end is fitted and locked in the spring locking groove 58, and the other end is brought into contact with the spring receiving projection 76. The unlocking operation tool G is retracted to the back side by the urging force of the homing helical spring H.

Next, the operation of the IC card ejection device configured as described above will be described with reference to FIGS.

First, the operation when inserting the IC card 100 will be described with reference to FIGS. 9, 10 and 11. FIG. 9B
FIG. 10 is a cross-sectional view taken along the line II-II in FIG.

Before the IC card 100 is inserted, the pair of left and right sliders C, C and the card slide plate B attached thereto are compressed springs D, D.
It is urged to the near side by.

As shown in FIG. 9, the top plate portion 20 of the device body chassis A and the slide plate body 42 of the card slide plate B are provided.
The IC card 100 is inserted on the card slide plate B while being inserted into the insertion space 32 formed therebetween, and is inserted into the back side. Then, the back end of the IC card 100 is bent by the bent pieces 44 of the card slide plate B.
, But when the IC card 100 is further pushed in,
The IC card 100, the card slide plate B, and the pair of left and right sliders C, C move integrally and move rearward, and at this time, the pair of left and right compression springs D, D contract to accumulate urging force. . In FIG. 9, the lock chassis E and the lock release operation tool G are not shown.

When the IC card 100 is further pushed in, the urging force accumulated in the compression springs D, D further increases, and the input / output terminals at the rear end of the IC card 100 are inserted into the connector 24 to be fitted. Will be connected. FIG. 10 shows this state. FIG.
In the state of 0, the lock mechanism F operates and the curl-shaped locking claws 50a, 50a of the card slide plate B are locked in the locking recesses 64, 64, so that the pushing operation force given to the IC card 100 is reduced. Even if it is released, the IC card 100, the card slide plate B, and the sliders C, C are fixedly held at the connector connection position against the urging force of the compression springs D, D. This completes the operation of inserting the IC card 100.

The operation of the lock mechanism F will be described in detail with reference to FIG. When the IC card 100 is inserted and the card slide plate B moves to the back side as shown in the direction of the arrow X integrally with the IC card 100, the lock rising piece 50 also moves in the direction of the arrow X at the same time. As shown in (a), the curl-shaped locking claws 50a, 50a at both ends of the locking rising piece 50 are connected to a pair of left and right arms 6 of the locking mechanism F.

Further, the lock rising piece 50 is indicated by an arrow X.
11B, the locking claws 50a push the tapered surfaces of the locking claws 66, 66 outward in the left-right direction, as shown in FIG. 11B. This pushing and spreading is performed smoothly because the locking claws 50a and 50a are curled and the locking claws 66 and 66 have a tapered surface. As a result, the pair of left and right arms 62, 62 are elastically extended from the mounting base in the directions indicated by arrows Z, Z.

Further, the lock rising piece 50 is indicated by an arrow X.
When it moves in the direction, the input / output terminals of the IC card 100 are connected to the connector. At this time, as shown in FIG. 11C, the locking claws 50a, 50a And the locking recesses 64, 64 are moved by the elastic restoring force of the arms 62, 62 so that the locking claw 50
a and 50a.

Thus, the lock function by the lock mechanism F is completed. In this locked state, the biasing force accumulated in the pair of left and right compression springs D, D is considerably large.

Next, the locked state is released and the IC card 1
The operation for discharging 00 will be described with reference to FIG.

[0045] If you operated <br/> press the operation knob 72 of the unlocking member G which is exposed on the back side of the device in the direction of arrow Y by a fingertip, as shown in (a) of FIG. 12, the locking A pair of left and right tapered surfaces 74, 74 of the release operation tool G are

, That is, the half located on the unlocking operation tool G side.
It is in contact only in the range of the thickness.

Further, when the operation knob 72 is pushed in the direction of arrow Y, as shown in FIG. 12B, the tapered surfaces 74, 74 of the unlocking operation tool G cause the unlocking cams 68, 68 to move in the left and right directions. Will be pushed out of the
When the push-out amount reaches a certain amount, the locking concave portions 64 of the lock mechanism F are locked at the both ends of the locking rising piece 50 as shown in FIGS. 12 (b) to 12 (c). It will separate from nail | claw 50a, 50a. That is, the locked state is released.

Then, a pair of left and right compression springs D, D, which had been blocked by the lock mechanism F, until then.
Is exerted, and the sliders C, C are pressed and moved in the arrow Y direction. Along with this, the card slide plate B is also pressed and moved in the same direction. This operation is shown in FIG.
This corresponds to a change from the state of 0 to the state of FIG. Since the bent pieces 44, 44 at the back end of the card slide plate B are in contact with the back end of the IC card 100, the input / output terminals of the IC card 100 are connected to the connector by the large urging force of the compression springs D, D. 24 can be pulled out by overcoming the large fitting resistance.

After the drawing is completed, the sliders C, C, the card slide plate B, and the IC card 100 are integrally moved in the direction of the arrow Y by the urging force of the compression springs D, D. A part of the front end of the IC card 100 protrudes outside the insertion space 32. The IC card 100 may be pulled out by hand with the protruding portion.

A point to be noted in the above-described operation of pulling out the IC card 100 is that the IC card 100
The force for pulling out the input / output terminal from the connector 24 against the large fitting resistance is not given by the operator but is due to the biasing force accumulated in the pair of left and right compression springs D, D. Is a point. The operator gives only the force for pushing and operating the unlocking operation tool G in order to release the locked state by the lock mechanism F. A relatively small operation force is required because the boosting effect of the cam action on the tapered surface acts on the release.

From the opposite viewpoint, the unlocking operation tool G
Since a large operating force does not act on the device, it is not necessary to make it so thick, and even if it is arranged on the back side of the device main body, the device main body does not needlessly be enlarged. Then, since the unlocking operation tool G is disposed on the back side of the device main body, the side surface portion of the device main body can be opened for disposing an extension function unit such as an extension slot.

[0051]

As described above, according to the present invention, the following effects can be obtained. That is, first, a sufficient biasing force is accumulated in the pair of left and right compression springs when the IC card is inserted, and the biasing force is developed when the lock is released, so that the IC can overcome the mating resistance between the input / output terminal and the connector. The card can be pulled out. Further, since the unlocking operation tool only releases the locked state and does not need to oppose the mating resistance, the operation force required for the sliding operation of the unlocking operation tool can be sufficiently small.

Further, since the unlocking operation tool is disposed on the back side of the device main body, the side portion of the device main body can be opened for disposing the extension function section.
