Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable electronic device capable of mounting a card-shaped electronic component such as a memory card or an interface card, and more particularly to a structure of an ejector for discharging the card-shaped electronic component. Regarding

[0002]

2. Description of the Related Art A portable book-type portable computer which is easy to carry and has high functionality is known in which a memory card for increasing the storage capacity and an interface card for communicating with the outside can be mounted. ing. A computer to which a card of this type can be attached has a card housing inside a housing having a keyboard. The card storage portion is connected to a card insertion opening opened on the side surface of the housing, and the card is inserted and removed through the card insertion opening. In addition, a connector to which the terminal portion of the card is detachably connected is arranged in the card housing portion.

Further, an ejector for guiding the card inserted from the card insertion port to the connector and ejecting the inserted card is installed in the card accommodation portion. The ejector includes a pressing piece that faces the connector-side end of the card, a push button that is exposed on the peripheral surface of the housing, and a linking mechanism that links the push button and the pressing piece. .

In this ejector, when the operator presses the push button with the fingertip, the movement of the push button is transmitted to the pressing piece through the linking mechanism, and the pressing piece advances toward the end portion of the card on the connector side. It Due to this advance, the card is pushed out in the direction to be detached from the connector, the connection between this card and the connector is released, and the card is projected from the card insertion port to the outside of the housing. There is.

By the way, when the card is connected to the computer and used, the push button is accidentally pressed,
If the card is pushed out of the card housing, the information stored in this card may be erased or the correct information may not be stored. Therefore, there is known a conventional computer in which a lock claw for catching a card inserted in the card storage portion is provided at the opening end of the card insertion opening.

According to this structure, even if the push button is accidentally pressed while the card is in use, the card is not pushed out of the card storage portion, and the information stored in the card is erased or destroyed. Can be prevented.

[0007]

However, in the conventional structure in which the lock claw is hooked on the card, the movement of the card is restricted by the lock claw, so that when the push button is pressed, the movement of the push button is directly linked. The force is transmitted to the pressing piece via the mechanism, and a force in the direction of pushing out the card is still applied to the end portion of the card on the connector side.

Therefore, an excessive force may be applied to the connection portion with the card or connector, and the expensive card or connector may be damaged. Similarly, since an unreasonable force is applied to the pressing piece of the ejector that comes into contact with the card, the pressing piece may be deformed and the function of the ejector may be impaired.

The present invention has been made under such circumstances, and an object thereof is to apply an unreasonable force to a card-shaped electronic component in a portable electronic device to which the card-shaped electronic component can be mounted. It is to obtain a structure capable of preventing the card-shaped electronic component from being undesirably pushed out.

[0010]

In order to achieve the above object, a portable electronic device according to a first aspect of the present invention is a portable electronic device, which has a casing having a peripheral surface in which a card insertion opening is opened, and an inside of the casing. Arranged and connected to the card insertion opening, a card housing portion for housing the card-shaped electronic component in a removable manner, a connector installed in the card housing portion, the card-shaped electronic component is detachably connected, The ejector is installed in the card accommodating portion and ejects the card-shaped electronic component from the card accommodating portion.

The ejector includes a pressing piece that faces the connector-side end of the card-shaped electronic component, and an operation lever that is exposed on the peripheral surface of the housing and is capable of projecting and retracting with respect to the housing. A linking mechanism that links the operation lever and the pressing piece, and when the operation lever is pushed into the housing, advances the pressing piece toward the card-shaped electronic component to separate the card-shaped electronic component from the connector. And a stopper that is movable between a lock position that locks the linkage mechanism and a lock release position that is disengaged from the linkage mechanism, and that disables pushing of the operation lever when the lock lever is moved to the lock position. A lock lever that is exposed on the peripheral surface of the casing and that moves the stopper to a lock position and an unlock position is provided.

According to a second aspect, the lock lever according to the first aspect is arranged between the operation lever and the insertion port on the peripheral surface of the housing, and the lock lever has the above-mentioned configuration. The lock lever is movably supported by the housing between a first position for holding the stopper in the lock position and a second position for holding the stopper in the lock release position. When it is moved to the first position, it has a retaining piece that advances into the card insertion opening and is caught by the card-shaped electronic component.

According to a third aspect of the present invention, the operating lever according to the first aspect has a storage position that is substantially flush with the peripheral surface of the housing and a use position that projects from the peripheral surface of the housing. It is characterized in that it is rotatably supported by the linkage mechanism.

According to a fourth aspect of the present invention, the operating lever according to the third aspect is pivotally supported by the linkage mechanism via a vertical axis extending in the thickness direction of the housing and horizontally rotated with respect to the housing. It is characterized by being moved.

According to a fifth aspect, the housing according to the fourth aspect is located at a position facing the pivotal support portion of the operation lever,
It is characterized in that it has a recess for exposing the pivotal support portion of the operation lever.

According to a sixth aspect of the present invention, the housing according to the fourth aspect, when the operation lever is rotated to the retracted position,
The operation lever has a storage portion into which an end portion opposite to the pivotal support portion is inserted, and the storage portion has a wall portion that abuts on the operation lever and holds the operation lever in the storage position. It is characterized by that.

[0017]

According to the structure described in claim 1, when the stopper is moved to the lock position via the lock lever, the stopper is caught by the linkage mechanism and restrains the movement of the linkage mechanism. Therefore, even if the operation lever is accidentally pressed when the card-shaped electronic component is used while being connected to the connector, the linkage mechanism linked to this operation lever is constrained, so the operation of pushing the operation lever itself is restricted. At the same time, the pressing piece also remains stationary, and it is not necessary to apply a load to the card-shaped electronic component in the direction of detaching it from the connector.

Therefore, it is possible to prevent the card-shaped electronic component from being pushed out without exerting an excessive force on the card-shaped electronic component or the connector. According to the structure described in claim 2, when the lock lever is moved to the first position and the movement of the linkage mechanism is restrained, the retaining piece of the lock working lever advances into the card insertion slot, and The positional relationship is such that the end of the electronic component opposite to the connector is opposed. Therefore, it is possible to recognize from the position of the lock lever whether or not the movement of the linkage mechanism is restricted.

Further, since the retaining piece of the lock lever has advanced into the card insertion slot, the retaining piece can hold the card-shaped electronic portion in the card accommodating portion while retaining it. Therefore, it is possible to prevent the card-shaped electronic component from being undesirably pushed out, in addition to restraining the linkage mechanism.

According to the structure described in claim 3, when the operation lever is rotated to the retracted position, the operation lever becomes substantially flush with the peripheral surface of the housing, and the fingertip is attached to the peripheral surface of the housing. The operating lever cannot be pushed in to some extent. Then, in order to press the operation lever with the fingertip, a conscious operation such as rotating the operation lever toward the use position is required, and it is possible to reliably prevent the operation lever from being inadvertently pushed.

At the same time, when the operating lever is rotated toward the use position, the operating lever projects from the peripheral surface of the housing, so that it is easy to put a fingertip on the operating lever and the pushing operation is facilitated. You can

According to the structure described in claim 4, since the operating lever is rotated horizontally with respect to the housing, the upper side or the lower side of the operating lever is particularly reduced when the operating lever is formed in a flat plate shape. It is not necessary to secure a wide space for storing the operation lever on the side, and a space for accommodating functional parts such as a battery and a hard disk drive can be easily secured here.

According to the structure described in claim 5, even when the operation lever is rotated to the retracted position, the periphery of the pivotal support portion of the operation lever is exposed to the outside of the housing through the recess. Therefore, if you insert your fingertip into the recess and press the pivotal support of the operating lever, this operating lever rotates about the pivotal support, and the end opposite to the pivotal support protrudes from the peripheral surface of the housing. To be done. Therefore, when the operation lever is rotated from the retracted position to the use position, it is easy to put a fingertip on the operation lever, and the operation lever can be easily pulled out.

According to the structure described in claim 6, when the operation lever is rotated to the retracted position, the end portion of the operation lever on the side opposite to the pivotal support portion abuts the wall portion of the storage portion, Further turning or pushing operation of the operating lever is restricted. Therefore, when the operation lever is rotated to the retracted position, it cannot be pushed further into the housing, and the retracted operation lever is forcibly pressed especially when the stopper is moved to the unlocked position. However, the card-shaped electronic component is not pushed out.

It slides between a standby position where 34b is arranged along the facing surface 23a of the connector 23 and a pressing position where the pressing pieces 34a and 34b are pushed out from the facing surface 23a toward the card-shaped electronic component 19.

The eject plate 35 reaches the position where the other end of the eject plate 35 opposite to the extension 37 is adjacent to the right side surface of the housing 2. An operation lever 40 is connected to the other end of the eject plate 35. This operating lever 40 is
It has a flat rectangular plate shape. The operation lever 40 is rotatably supported by the eject plate 35 via a vertical axis 41 along the thickness direction of the housing 2, and the pivot portion of the operation lever 40 is biased to one end side of the operation lever 40. ing. Therefore, the operating lever 40 is rotated at a substantially right angle from the use position extending in the sliding direction of the eject plate 35 as shown in FIGS. 4 and 5 and the use position as shown in FIGS. 2 and 3. It is rotatable about the storage position.

An opening 42 for exposing the operation lever 40 is formed on the right side surface of the bottom case 3. The opening 42 is in the form of an elongated slit extending in the front-rear direction of the bottom case 3, and is located side by side with the card insertion slot 20. Then, when the operation lever 40 is rotated to the use position, most of the operation lever 40 protrudes to the right side of the housing 2, and the ejecting plate 35 is slid by pressing the protruding end with a fingertip. It has become so.

Further, as shown in FIG. 1, a recess 46 continuous with the opening 42 is formed on the right side surface of the housing 2.
The recess 46 is biased toward one end of the opening 42 so as to correspond to the pivotal support of the operating lever 40.
When the operation lever 40 is rotated to the retracted position,
The corner of the operating lever 40 on the pivotal support side is exposed in the recess 46. Therefore, as shown by the arrow in FIG.
When a corner of the operating lever 40 is pressed by inserting a fingertip into the recess 46, the operating lever 40 is rotated, and the other end of the operating lever 40 opposite to the pivotal support part thereof partially projects from the opening 42. ing.

According to this structure, when the operation lever 40 rotated to the storage position is pulled out to the use position, the corner portion of the operation lever 40 is pressed as described above, and the operation lever 4 is pushed.
By projecting a part of 0 on the right side surface of the housing 2, the projecting portion of the operation lever 40 can be pinched with a fingertip. Therefore, the operation lever 40 can be easily pulled out from the retracted position to the use position.

A through hole 47 is opened in the central portion of the eject plate 35. The through hole 47 is formed in the eject plate 35.
It has a long hole shape along the slide direction. This through hole 4

Therefore, the eject plate 35 is constantly urged toward the operation lever 40 by the compression coil spring 52, and is held at the standby position. And
When the operation lever 40 is rotated to the use position,
Most of the operating lever 40 is projected to the right side of the housing 2.

The operation lever 4 is provided in the card accommodating portion 18.
A stopper 60 for limiting the pushing of 0 is installed. The stopper 60 includes a metal slider 61 supported on the upper surface of the ceiling wall 14. The slider 61 is arranged between the one guide rail 22 a and the eject plate 35. The slider 61 is provided at one end thereof with an arm portion 62 extending in a direction orthogonal to the sliding direction of the eject plate 35. The arm portion 62 passes below the eject plate 35, and its tip is led out to the side of the eject plate 35 opposite to the slider 61.
A locking claw 63 that is bent upward is formed at the tip of the arm portion 62.

The eject plate 35 is provided with a locking recess 64 at the side edge portion on the side corresponding to the locking claw 63. The locking concave portion 64 faces the locking claw 63 when the eject plate 35 is slid to the standby position.

For this reason, the slider 61 has its locking claws 6
3 is locked at the locking recess 64 and the locking claw 6
3 is slidably supported on the upper surface of the ceiling wall 14 to the unlocked position separated from the locking recess 64, and the slide plate 61 extends in a direction orthogonal to the sliding direction of the eject plate 35. It is designed to slide.

The slider 61 is provided with a lock lever 66 at the other end opposite to the arm portion 62. The lock lever 66 is exposed on the right side surface of the housing 2 and can be operated with a fingertip. Therefore, the lock lever 66 is slidable in the front-rear direction of the housing 2 between the first position for holding the slider 61 in the lock position and the second position for holding the slider 61 in the unlock position. It has become.

The lock lever 66 is provided on the right side surface of the housing 2 with the operation lever 40 and the card insertion slot 20.
It is located between and. At the end of the lock lever 66 on the card insertion port 20 side, a retaining piece 67 is integrally formed. As shown in FIG. 5, the retaining pieces 67 are
When the lock lever 66 is slid to the first position,
The card is inserted into the opening portion of the card insertion opening 20 and faces the end of the card-shaped electronic component 19 inserted into the card housing portion 18 opposite to the terminal portion 26.

In the computer 1 having such a configuration, when the card-shaped electronic component 19 is inserted into the card insertion slot 20, both sides of the card-shaped electronic component 19 can slide in the fitting grooves 24 of the guide rails 22a and 22b. To fit.
By this fitting, the card-shaped electronic component 19 is fitted into the fitting groove 24.
The terminal portion 26 at the tip thereof is electrically connected to the pin 25 of the connector 23. At this time, the pressing pieces 34a and 34b of the slide plate 32 face the terminal portions 26 of the card-shaped electronic component 19.

The card-shaped electronic component 19 is placed in the card accommodating portion 18
In order to take it out of the housing 2, first, a fingertip is inserted into the recess 46 on the right side surface of the housing 2, and the corner of the operation lever 40 exposed in the recess 46 on the pivotal support side is pushed in. Then, the end portion of the operation lever 40 on the opposite side to the pivotal support portion projects from the opening portion 42 to the right side of the housing 2, so that the projecting portion of the operation lever 40 is grasped and pulled out, as shown in FIG. First, the operation lever 40 is rotated to the use position.

In this state, as shown in FIG. 8, the operating lever 40 is pushed in with a fingertip, and the eject plate 35 is slid to the pushing position. When the eject plate 35 is slid, the rotation lever 38 is rotated counterclockwise as shown in FIG. 7, and the slide plate 32 is slid in the direction opposite to the sliding direction of the eject plate 35. By this slide, the terminal portion 26 of the card-shaped electronic component 19 pushes the pressing piece 34.
The card-shaped electronic component 19 is pressed by a and 34b.
Are extruded in a direction of separating from the connector 23.

As a result, the end of the card-shaped electronic component 19 projects from the card insertion opening 20 to the outside of the housing 2. Therefore, the projecting portion of the card-shaped electronic component 19 is grasped with fingers and the card-shaped electronic component 19 is grasped. 19 is pulled out from the card insertion slot 20.
As a result, the card-shaped electronic component 19 is transferred to the card housing portion 18
Can be taken from.

When the pressing of the operating lever 40 is released, the ejecting plate 35 is pushed back to the standby position by the urging force of the compression coil spring 52. Therefore, the operation lever 40 again projects to the right side of the housing 2, so that after the card-shaped electronic component 19 is taken out, the operation lever 40 is rotated toward the storage position, as shown in FIGS. like,
It is desirable to push it into the storage portion 45.

By the way, when the lock lever 66 is slid toward the first position when the card-shaped electronic component 19 is housed in the card housing portion 18 as described above,
The slider 61 is slid to the lock position via the lock lever 66, and the locking claw 63 at the tip of the arm 62 is caught in the locking recess 64 of the eject plate 35, as shown in FIG.

In this case, the locking claw 63 is used as the eject plate 3
Since the engaging claw 63 is caught in the engaging recess 64 from a direction orthogonal to the sliding direction of 5, the slide of the eject plate 35 is restricted.

Therefore, when the card-shaped electronic component 19 is used while being connected to the connector 23, even if the operating lever 40 is accidentally pressed with a fingertip, the eject plate 35 that slides integrally with the operating lever 40 is restrained. Therefore, the operation lever 40 cannot be pushed in.
Therefore, the rotating lever 38 and the slide plate 32 remain stationary, and the pressing pieces 34a and 34b do not press the terminal portion 26 of the card-shaped electronic component 19 in the direction of separating from the connector 23.

According to this ejector 31, the pressing force of the operation lever 40 does not need to be transmitted to the card-shaped electronic component 19, so that the card-shaped electronic component 19 and the connector 23 are not forcedly forced and the card-shaped electronic component 19 is not forced. It is possible to prevent the electronic component 19 from being pushed out. Therefore, it is possible to reliably prevent damage to the card-shaped electronic component 19 and the connector 23, which have high added value.

Similarly, the pressing pieces 34a and 34b for pressing the card-shaped electronic component 19, the connecting portion between the slide plate 32 and the rotating lever 38, and the connecting portion between the locking claw 37a and the connecting hole 38a are also impossible. Since no force is applied, damage to the ejector 31 can be prevented.

Further, when the lock lever 66 is slid to the first position as described above, the retaining piece 67 advances into the opening of the card insertion slot 20, and the card-shaped electronic device accommodated in the card accommodating portion 18 is reached. Opposite the ends of the part 19. Therefore, it is possible to recognize from the position of the lock lever 66 whether or not the eject plate 35 is restrained,
This is more convenient in preventing erroneous operation of the operation lever 40.

Moreover, since the retaining piece 67 faces the card-shaped electronic component 19, the retaining piece 67 can prevent the card-shaped electronic component 19 from retaining in the card housing portion 18. Therefore, the eject plate 3
5 and the card-shaped electronic component 19
It is possible to prevent double undesired extrusion and improve the reliability.

According to the above construction, the operation lever 40
When the control lever 40 is rotated to the retracted position, the operation lever 40 continues substantially flush with the right side surface of the housing 2, and the operation lever 40 itself has a flat plate shape. The operation lever 40 cannot be pushed into the housing 2 by pressing the surface with a fingertip. Then, in order to push in the operating lever 40 with a fingertip, the operating lever 40
It is necessary to perform a conscious operation of rotating the to the use position and projecting it to the right side of the housing 2. Therefore, the operating lever 40
Inadvertent pushing of the card-shaped electronic component 19 can be prevented, which also contributes effectively to preventing the card-shaped electronic component 19 from being pushed out.

Further, when the operation lever 40 is rotated to the retracted position, the end portion of the operation lever 40 on the side opposite to the pivotal support portion enters the storage portion 45 and the wall portion 44 on the upper surface of the ceiling wall 14. Since it abuts against the
Pushing and rotation of 0 are restricted. Therefore, when the operation lever 40 is rotated to the retracted position, the operation lever 40 and the eject plate 35 cannot be pushed into the housing 2 any more.

Therefore, even if the stored operation lever 40 is further pressed by the fingertip when the eject plate 35 is not restrained, the eject plate 35 remains stationary and the card-shaped electronic component 19 is unexpectedly pushed out. Can be prevented.

Further, in the case of the above configuration, since the flat operation lever 40 rotates horizontally with respect to the housing 2, it is necessary to secure a wide space below the operation lever 40 for storing the operation lever 40. There is no. Therefore, the operating lever 4
A mounting part 13 that opens to the right of the housing 2 below 0
Can be formed, and the hard disk drive device 12 can be arranged therein without difficulty.

In the above embodiment, the operating lever is rotated horizontally with respect to the housing, but the present invention is not limited to this, and may be rotated vertically with respect to the housing. . Further, the portable electronic device according to the present invention is not limited to a portable computer, and can be implemented in the same way even with a text creation device, for example.

According to the first aspect of the present invention, when the card-shaped electronic component is used while being connected to the connector, even if the operation lever is pressed by mistake, the linkage mechanism connected to the operation lever is restricted. Therefore, the pushing operation itself of the operating lever is restricted, and the pressing piece also remains stationary, so that the card-shaped electronic component is not pressed in the direction to be detached from the connector. Therefore, it is possible to prevent the card-shaped electronic component from being pushed out without damaging the card-shaped electronic component or the connector, and also to prevent damage to the ejector.

According to the second aspect, it is possible to recognize from the position of the lock lever whether or not the movement of the linkage mechanism is restricted, which is convenient for preventing erroneous operation of the operation lever. Further, since the retaining piece of the lock lever has advanced into the card insertion opening, the retaining piece can prevent the card-shaped electronic component from retaining in the card housing portion. Therefore, undesired extrusion of the card-shaped electronic component can be doubly prevented in addition to the constraint of the linkage mechanism, and the reliability is improved accordingly.

According to the third aspect, when the operation lever is rotated to the retracted position, the operation lever becomes substantially flush with the peripheral surface of the housing, so that the fingertip is not attached to the peripheral surface of the housing. The operating lever cannot be pushed in. Then, in order to press the operation lever with a fingertip, a conscious operation such as rotating the operation lever toward the use position is required, and it is possible to reliably prevent accidental pushing of the operation lever. At the same time, when the operation lever is rotated toward the use position, the operation lever projects from the peripheral surface of the housing, so that it is easy to put a fingertip on the operation lever and the pushing operation can be performed easily.

According to the fourth aspect of the present invention, since the operating lever rotates horizontally with respect to the housing, the operating lever is located above or below the operating lever, especially when the operating lever is formed in a flat plate shape. It is not necessary to secure a wide space for storing the data, and a space for accommodating functional parts such as a battery and a hard disk drive can be easily secured here.

According to the fifth aspect, when the fingertip is inserted into the recess and the pivotal support portion of the operation lever is pressed, the end portion of the operation lever opposite to the pivotal support portion is projected from the peripheral surface of the housing. When the operation lever is rotated from the retracted position to the use position, the operation lever can be easily pulled out.

According to the sixth aspect, when the operation lever is rotated to the storage position, it cannot be pushed further into the housing. Therefore, especially when the stopper is moved to the unlocked position, the storage lever is stored. Even if the operated lever is forcibly pressed, the card-shaped electronic component is not pushed out.
