A coil spring 24S that is interposed therebetween and urges the eject member 24J in the SD card SDC ejecting direction, and selectively holds or releases the eject member 24J with respect to the base member 12 in accordance with the attaching / detaching operation of the SD card SDC. And an ejection member control unit that performs control.

  The eject member control unit is formed around the heart cam and a substantially heart-shaped cam element (heart cam) formed on the side wall 12RW side of the eject member 24J as disclosed in, for example, Japanese Patent Application Laid-Open No. 2004-31416. A lever guide groove comprising a plurality of step portions, a gate-shaped cam lever (not shown) whose one end is connected to the hole of the side wall 12RW and the other end is slid along the lever guide groove, and the above-mentioned And a pressing spring 10LF (see FIG. 2) of the cover member 10 of the first embodiment.

  The holding spring 10LF biases the bent end of the cam lever so as to be in sliding contact with the guide surface of the lever guide groove. As a result, one end of the cam lever is guided sequentially through each guide groove constituting the lever guide groove following the operation of the eject member 24J, and is temporarily held on the cam surface formed on the heart cam. As a result, the eject member 24J with the SD card SDC or the like is held in the card accommodating portion. Then, when one end of the cam lever is separated from the cam surface by further pushing operation of the SD card SDC or the like, the eject member 24J with the SD card SDC or the like is moved in the card ejection direction by the biasing force of the coil spring 24S. It is done.

  As shown in FIG. 1 in an enlarged manner, the eject member 24J has a card receiving portion 24JR that extends to the card accommodating portion 12A side substantially perpendicular to the portion where the above-described cam element and lever guide groove are formed. ing. The card receiving portion 24JR receives a substantially perpendicular corner portion at the front end portion of the SD card SDC, or the front end portions of the HG-Duo card 22 and the Duo card. Further, when the SD card SDC is attached to the card accommodating portion 12A, the inner end surface 24JE connected to the portion where the card receiving portion 24JR intersects in the portion where the cam element and the lever guide groove are formed on the inside is shown in FIG. As shown in D), the L-shaped stopper portion 16R of the slide block 16 is received.

  The slide block 16 is slidably disposed along the Y coordinate axis in FIG. 3 in the grooves 12Ga and 12Gb formed on both sides of the protrusion 12P formed on the bottom of the base member 12. As a result, the slide block 16 moves into the card receiving portion 12A as shown in FIG. 4 (A) or retreats from the entry position as shown in FIG. It is slid between the standby position received by 24JE. The Y coordinate axis is taken along the direction orthogonal to the X coordinate axis along the attaching / detaching direction of the SD card SDC or the like in the orthogonal coordinate system in FIG.

  As shown in FIG. 1, the slide block 16 is arranged so as to face the inner peripheral portion of the side wall 12RW of the base member 12, and has an L-shaped stopper portion 16R for positioning the slide block 16 at the standby position described above, The engaging step 16e is formed so as to be opposed to the inner peripheral portion of the 12RW and formed integrally with one side portion of the stopper portion 16R, and includes a bottom portion disposed in the groove portions 12Ga and 12Gb.

  As shown in FIG. 3, the height from the bottom of the slide block 16 to the upper surface of the stopper portion 16R is set so that the upper surface of the stopper portion 16R is on the same plane as the upper surface of the ejection member 24J. Yes.

  The locking step portion 16e has a flat portion with which one end of the hook-shaped first lock portion 10fa of the lock member 10FA contacts when the slide block 16 is in the guide position.

  Thus, the locked state of the slide block 16 is also maintained by maintaining the state where the locking step portion 16e and the first lock portion 10fa are in contact with each other.

  On the outer peripheral surface of the locking step portion 16e and the stopper portion 16R that enters the card accommodating portion 12A, a guide for guiding the end portion of the inserted HG-Duo card 22 and the Duo card toward the contact terminal 18ai. A surface 16Sa and a guide surface 16Sb are formed. The guide surface 16Sb is formed along the X coordinate axis in FIG. The guide surface 16Sa is inclined so as to intersect the guide surface 16Sb with a predetermined obtuse angle and to be close to the side wall 12RW.

  A guide groove 16g is formed at the bottom of the slide block 16 along the Y coordinate axis in FIG. A protrusion 12P is engaged with the guide groove 16g so that the slide block 16 can slide.

  Further, between the end of the slide block 16 and the inner peripheral portion of the side wall 12RW, the slide block 16 in the groove portions 12Ga and 12Gb enters the card housing portion 12A and engages with the peripheral edges of the groove portions 12Ga and 12Gb. A coil spring 20 is provided for biasing to restrain. Thus, when the hook-shaped first lock portion 10fa of the lock member 10FA is unlocked, the slide block 16 in the standby position is returned to the entry position by the biasing force of the coil spring 20. It will be.

  Furthermore, a lock fitting 28 as a lock mechanism control piece is supported in a recess 12D inside the side wall 12RW that forms a part of the card slot 12CS in the card accommodating portion 12A, at a position below the lock member 10FA. . When the SD card SDC is inserted through the card slot 12CS, the lock fitting 28 brings the lock member 10FA into an unlocked state. Further, when the HG-Duo card 22 and the Duo card are inserted through the card slot 12CS, the lock fitting 28 is locked because the lock portion 10fb of the lock member 10FA is inserted into the opening 28a and is kept locked. The locked state of the member 10FA is also maintained.

  As shown in FIG. 1, the lock fitting 28 has a fixed portion 28f supported on the inner side of the side wall 12RW, and a Y coordinate axis (so-called connector width direction) connected to the fixed portion 28f via a bent portion 28b. And a movable piece 28m that can be elastically displaced along.

  As shown in FIG. 4A, the distance La from the bent portion of the movable piece 28m to the inner peripheral surface of the side wall 12LW is slightly smaller than the horizontal width of the SD card SDC, and is an HG-Duo card. It is set to be larger than the width dimension of 22.

  The movable piece 28m has an opening 28a at one end. When the tip of the SD card SDC is not inserted into the card slot portion 12CS, the second lock portion 10fb of the lock member 10FA penetrates the opening 28a.

  The bent portion 28b of the movable piece 28m of the lock fitting 28 is exposed in the guide groove 12FR through the opening of the wall portion that forms the guide groove 12FR. Thereby, when the SD card SDC passes through the card slot 12CS, the side portion of the end portion in the traveling direction of the SD card SDC comes into contact with the bent portion 28b.

  Thereby, when the SD card SDC passes through the card slot 12CS, the bent portion 28b of the movable piece portion 28m of the lock fitting 28 has a Y coordinate axis so that one end thereof is close to the fixed portion 28f against its elastic force. Will be pressed along. Accordingly, the peripheral edge of the opening 28a of the movable piece 28m of the lock fitting 28 is separated from the second lock 10fb of the lock member 10FA. As a result, since the lock member 10FA is unlocked, the first lock portion 10fa is pushed up along the Z coordinate axis in FIG. 3 toward the inner peripheral surface of the cover member 10 by the end portion of the SD card SDC that further advances. It is done.

  In such a configuration, when the SD card SDC is mounted in the card housing portion 12A, first, the contact pad SDE of the SD card SDC faces the inner peripheral surface of the cover member 10, as shown in FIG. The SD card SDC is inserted into the guide groove 12FR of the card slot 12CS in a posture (hereinafter also referred to as a reverse insertion posture). Next, as shown in FIG. 4B, one side of the end of the SD card SDC in the traveling direction has a bent portion 28b of the movable piece 28m of the lock fitting 28 exposed in the guide groove 12FR. Press. At this time, the bent portion 28b is pressed along the Y coordinate axis so that one end of the movable piece portion 28m is close to the fixed portion 28f. Thereby, one end of the movable piece portion 28m is released from the opening 28a of the lock fitting 28 from the state shown in the enlarged view of FIG. 5A from the second lock portion 10fb shown in FIG. By moving to the state, the second lock portion 10fb of the lock member 10FA is set to the unlocked state. At that time, the other side portion of the end portion in the traveling direction of the SD card SDC is in sliding contact with the inner peripheral surface of the side wall 12LW.

  Subsequently, as shown in FIG. 4C, when the SD card SDC is further inserted, the end of the SD card SDC in the moving direction causes the locking step 16e of the slide block 16 and the side wall 12RW to move inside. It is pushed up along the Z coordinate axis in FIG. 3 from between the periphery. Thereby, as shown in FIG. 5C, the first lock portion 10fa and the locking step portion 16e are separated from each other, and the slide block 16 is unlocked.

  Subsequently, as shown in FIG. 4C, the end portion of the SD card SDC in the advancing direction comes into contact with the guide surface 16Sa of the slide block 16, and is further pushed in, so that FIG. As shown in FIG. 5 (D), the slide block 16 is slid from the aforementioned entry position to the standby position against the urging force of the coil spring 20. At this time, the corner of the SD card SDC in the traveling direction is received by the card receiving portion 24JR of the eject member 24J. Then, when the SD card SDC is further pushed in, the eject member control unit holds the eject member 24J with the SD card SDC in the card housing portion 12A, so that the installation of the SD card SDC is completed. Accordingly, the contact pad SDE of the SD card SDC is brought into contact with the contact portion of the contact terminal 18ai with a predetermined pressure. On the other hand, when the SD card SDC is ejected from the card housing portion 12A, the SD card SDC is further pushed in, and the SD card SDC is moved together with the eject member 24J by the urging force of the coil spring 24S. It is discharged through 12CS. At that time, when the slide block 16 is returned to the above-described entry position, the first lock portion 10fa of the lock member 10FA and the movable piece portion 28m of the lock fitting 28 are returned to their original positions. As a result, the slide block 16 is locked.

  When the HG-Duo card 22 or the Duo card is mounted in the card accommodating portion 12A instead of the SD card SDC, as shown in FIG. 3, the side of the HG-Duo card 22 or the Duo card is inserted into the card slot 12CS. When passing through, it passes without interfering with the bent portion 28b of the movable piece 28m of the lock fitting 28. At this time, since the second lock portion 10fb is inserted into the opening 28a of the lock fitting 28 to maintain the locked state, the lock member 10FA is maintained in the locked state. As a result, the end portion of the inserted HG-Duo card 22 or Duo card in the traveling direction is guided to the normal position toward the contact terminal 18ai by the guide surface 16Sa and the guide surface 16Sb of the slide block 16. .

  Further, as shown in FIG. 6, when the side portion of the HG-Duo card 22 passes through the card slot 12CS, one side portion of the HG-Duo card 22 inserted in an oblique posture is inserted into the guide groove 12FR. In some cases, the bent portion 28b of the movable piece 28m of the lock fitting 28 is pressed. In this case, the second lock portion 10fb of the lock member 10FA is released from the opening 28a of the lock fitting 28 and the second lock portion 10fb is unlocked, but one side portion of the HG-Du card 22 Interferes with the upper wall 12FW and the contact between the first locking member 10fa and the locking step 16e is maintained, so that the locked state of the slide block 16 is maintained. In addition, the first lock portion 10fa of the lock member 10FA and the locking step portion 16e are separated from each other, and one side portion of the HG-Duo card 22 interferes with the upper wall 12FW so that the slide block is unlocked. In some cases, the guide groove 12FR is separated from the guide groove 12FR. In this case, the locked state of the lock member 10FA is maintained because the second lock portion 10fb of the lock member 10FA is maintained in the locked state inserted into the opening 28a. Therefore, as shown in FIG. 6, even if one side portion of the HG-Duo card 22 inserted in an oblique posture is engaged with the guide groove 12FR, the slide block 16 is erroneously inserted. Thus, it is possible to reliably avoid sliding from the aforementioned entry position to the standby position.

  FIG. 7 shows the external appearance of a second embodiment of the card connector according to the present invention.

  In the first embodiment shown in FIG. 2, the slide block 16 and the lock fitting 28 are provided only inside the side wall 12RW.

And a second lock portion 30fp inserted into the opening 28a of the lock fitting 28. The second lock portion 30fp is formed so as to be substantially orthogonal to the first lock portion 30fa. An opening 30a is formed around the distal end portion of the lock member 30FA and the first lock portion 30fa and the second lock portion 30fp.

  Further, a plurality of openings 30di (i = 1 to 8) are formed at positions on the upper surface portion adjacent to the pressing spring 30C and directly above the contact terminals 19ai. On the periphery of each opening 30di, a bent piece 30t is formed that protrudes toward the card accommodating portion. The folded piece 30t is in contact with the end of the inserted SD card SDC, so that the SD card SDC is erroneously inserted into the card slot from the end opposite to the end in the normal insertion direction. Thus, damage to the contact terminal due to so-called reverse insertion is avoided.

  The card accommodating portion 32A in the base member 32 is open at the upper end and the end opposite to the contact terminal fixing portion described later. The card accommodation unit 32A selectively accommodates one IC card of the SD card SDC or Duo card (not shown) on a common plane, that is, is shared by two types of IC cards. It is assumed to be a card accommodating part.

  Since the base member 32 is covered with the cover member 30 described above, one of the SD card SDC and the Duo card is selectively passed through one end of the card housing portion 32A. The card slot 32CS is formed.

  Both ends of the peripheral edge of the common card slot 32CS have guide grooves 32FR for guiding both sides of the SD card SDC to be inserted. The upper wall portion 32FW at the periphery of the guide groove 32FR extends a predetermined length along the side walls 32RW and 32LW. Such guide grooves are also formed on the inner side of the guide walls 32RG and 32LG that are separated from the upper wall portion 32FW by a predetermined distance in the direction inside the card storage portion 32A.

  The base member 32 is integrally molded with a molded resin material, for example. The base member 32 includes side walls 32RW and 32LW that form both sides of the card housing portion 32A, a Duo card contact terminal 18ai (i = 1 to 14), and an SD card SDC contact terminal 19ai (i = 1 to 1). 9) includes a contact terminal fixing wall portion 32BW, and side walls 32RW and 32LW and a bottom portion connecting the contact terminal fixing wall portion 32BW.

  On the outer surface of the side wall 32LW, a plurality of claw portions (not shown) are formed at predetermined intervals corresponding to the engagement holes of the cover member 10 described above. Although not shown in the figure on the outer surface of the side wall 32RW, a plurality of similar claw portions are formed at predetermined intervals corresponding to the engagement holes of the cover member 30 described above.

  As shown in FIG. 8, the inner side portion of the side wall 32LW holds one IC card of the SD card SDC or the Duo card in the card storage portion 32A, and one card from the card storage portion 32A. An eject mechanism 34 for selectively discharging the IC card is provided.

The engaging step 36B is formed integrally with one side of the stopper portion, and includes a bottom portion disposed in the guide groove.

  The height from the bottom of the slide block 36 to the upper surface of the stopper portion is set so that the upper surface of the stopper portion is on the same plane as the upper surface of the side wall 32RW.

  The locking step portion 36B has a flat portion with which one end of the band-shaped first lock portion 30fa of the lock member 30FA contacts when the slide block 36 is in the entry position.

  Thus, the locked state of the slide block 36 is maintained by maintaining the state where the locking stepped portion 36B and the first lock portion 30fa are in contact with each other.

  A guide surface 36Sa and a guide surface 36Sb for guiding the end of the inserted Duo card toward the contact terminal 18ai are provided on the outer peripheral surface of the locking step portion 36B and the stopper portion entering the card storage portion 32A. Is formed. The guide surface 36Sb is formed along the X coordinate axis in FIG. The guide surface 36Sa is inclined so as to intersect the guide surface 36Sb with a predetermined obtuse angle and to be close to the side wall 32RW.

  Further, between the end of the slide block 36 and the inner peripheral portion of the side wall 32RW, a coil that energizes the slide block 36 in the guide groove so as to enter the card housing portion 32A and restrain it at the periphery of the guide groove. A spring 20 is provided.

  The slide block 38 is slidably disposed along a Y coordinate axis in FIG. 8 in a guide groove (not shown) formed in the bottom of the base member 32. As a result, as shown in FIG. 8, the slide block 38 has an entry position that has entered the card storage portion 32A and a guide wall 38Sb of the slide block 38 to be described later and a wall surface that forms a guide groove 32FR. It is made to slide between the retracted standby positions as shown in FIG.

  The slide block 38 is arranged so as to face the inner peripheral portion of the side wall 32LW of the base member 32, and faces the inner peripheral portion of the side wall 32LW, and an L-shaped stopper portion that positions the slide block slide block 38 at the standby position described above. The locking step portion 38B formed integrally with the one side portion of the stopper portion and the bottom portion disposed in the guide groove are configured.

  The height from the bottom of the slide block 38 to the upper surface of the stopper portion is set so that the upper surface of the stopper portion is on the same plane as the upper surface of the side wall 32LW.

  The locking step portion 38B has a flat portion with which one end of the band-shaped first lock portion 30fa of the lock member 30FA contacts when the slide block 38 is in the entry position.

  Thus, the locked state of the slide block 38 is maintained by maintaining the state where the locking stepped portion 38B and the first lock portion 30fa are in contact with each other.

  A guide surface 38Sa and a guide surface 38Sb for guiding the end portion on the advancing side of the inserted Duo card toward the contact terminal 18ai are provided on the outer peripheral surface of the locking step portion 38B and the stopper portion entering the card storage portion 32A. Is formed. The guide surface 38Sb is formed along the X coordinate axis in FIG. The guide surface 38Sa is inclined so as to intersect the guide surface 38Sb with a predetermined obtuse angle and to be close to the side wall 32LW.

  Further, between the end of the slide block 38 and the inner peripheral portion of the side wall 32LW, the coil that urges the slide block 38 in the guide groove to enter the card housing portion 32A and restrain it at the periphery of the guide groove. A spring (not shown) is provided.

  In such a configuration, when the SD card SDC is mounted in the card housing portion 32A, first, both sides of the SD card SDC are inserted into the guide grooves 32FR of the card slot 32CS in a reverse insertion posture. Next, both side portions of the end portion in the traveling direction of the SD card SDC press the bent portion 28b of the movable piece portion 28m of each lock fitting 28 exposed at the opening portion of each guide groove 32FR. At this time, the bent portion 28b is pressed along the Y coordinate axis so that one end of the movable piece portion 28m is close to the fixed portion 28f. As a result, one end of each movable piece 28m is moved to a state in which the second lock portion 30fp is released from the opening 28a of the lock fitting 28, so that each second lock portion 30fp of the lock member 30FA is moved. Set to unlocked state.

  Subsequently, when the SD card SDC is further inserted, one of the first lock portions 30fa of the unlocked lock member 30FA is used for locking the slide block 36 by the end portion in the traveling direction of the SD card SDC. It is pushed up along the Z coordinate axis in FIG. 8 from between the step portion 36B and the inner peripheral portion of the side wall 32RW. As a result, the locking step portion 36B and the first lock portion 30fa are separated from each other, and the slide block 36 is unlocked.

  In addition, the other first lock portion 30fa of the unlocked lock member 30FA is connected to the locking step portion 38B of the slide block 38 and the inner peripheral portion of the side wall 32LW by the end portion in the traveling direction of the SD card SDC. Is pushed up along the Z coordinate axis in FIG. As a result, the locking step portion 38B and the first lock portion 30fa are separated from each other, and the slide block 38 is unlocked.

  Subsequently, after the two locations at the end in the traveling direction of the SD card SDC abut against the guide surface 36Sa of the slide block 36 and the guide surface 38Sa of the slide block 38, the slide blocks 36 and 38 are coiled by being further pushed in. The spring 20 is slid from the approach position to the standby position against the urging force of the spring 20. At that time, the chamfered portion at the end of the SD card SDC in the traveling direction is received by the card receiving portion 34JR of the eject member 34J. When the SD card SDC is further pushed in, the eject member 34J with the SD card SDC is held in the card housing portion 32A by the eject member control unit, so that the mounting of the SD card SDC is completed. Accordingly, the contact pad SDE of the SD card SDC is brought into contact with the contact portion of the contact terminal 18ai with a predetermined pressure.

  When a Duo card is installed in the card housing portion 32A instead of the SD card SDC, both sides of the Duo card interfere with the bent portion 28b of the movable piece portion 28m of the lock fitting 28 when passing through the card slot 32CS. Pass with no. At this time, the lock member 30FA is maintained in the locked state because the second lock portion 30fp is maintained in the locked state where the lock fitting is inserted into the opening 28a. As a result, the end of the inserted Duo card in the advancing direction is in a normal position toward the contact terminal 18ai by the guide surface 36Sa and the guide surface 36Sb of the slide block 36 and the guide surface 38Sa and the guide surface 38Sb of the slide block 38.

Has been. Similarly to the example shown in FIG. 1, the card connector includes an ejection mechanism, a lock bracket, a slide block (not shown), and the like similar to the eject mechanism 24, the lock bracket 28, and the slide block 16 described above. Yes.

  The cover member 40 having a gate-shaped cross-sectional shape is formed by performing processing such as punching or bending on a thin metal material. A plurality of substantially rectangular engaging holes are formed on both side surfaces of the cover member 40, respectively.

  The cover member 40 is fixed to the base member 42 by engaging each engagement hole with each claw portion of the base member 42.

  In addition, a pressing spring (not shown) that movably supports a cam lever (not shown) in the eject mechanism is provided on one side of the upper surface connecting the both side surfaces of the cover member 40. The base end portion of the holding spring having elasticity is formed integrally with the cover member 40. The pressing spring is formed, for example, by punching a part of the cover member 40 toward the inside thereof by press working.

  Press pieces 40FB and 40FC formed at a predetermined interval are formed at a position on the card slot 42CS side on the upper surface portion of the cover member 40 and directly above the card accommodating portion 42A. The tip portions of the elastically displaceable pressing pieces 40FB and 40FC respectively enter the card housing portion and urge the inserted SD card SDC toward the card housing portion. As a result, when the SD card SDC is ejected, a sharp jump-out of the SD card SDC is avoided. The base end portions of the pressing pieces 40FB and 40FC are formed integrally with the other portions of the upper surface portion of the cover member 40, respectively. At the tip portions of the pressing pieces 40FB and 40FC, there are contact portions that contact the surface of the inserted SD card SDC. Openings are formed around the tip portions of the pressing pieces 40FB and 40FC, respectively.

  A slide block lock member 40FA is formed on the upper surface of the cover member 40. The slide block lock member 40FA is provided between one side surface portion of the cover member 40 and the pressing piece 40FB. The slide block lock member 40FA (hereinafter also referred to as the lock member 40FA) is formed integrally with other parts. The lock member 40FA brings the slide block into a locked state or an unlocked state with respect to the base member 42 in accordance with the attachment / detachment of the SD card SDC.

  The base end portion of the lock member 40FA is formed integrally with the other part of the upper surface portion of the cover member 40. The front end portion of the lock member 40FA that can be elastically displaced along the Z coordinate axis (so-called connector height direction) is formed by punching the upper surface portion of the cover member 40 toward the card housing portion. An opening is formed around the lock member 40FA. When the above-described slide block is at a predetermined entry position, the lock member 40FA includes a first hook-shaped lock portion disposed between the inner peripheral surface of the side wall 42RW and the step portion for locking the slide block; It has the 2nd lock | rock part inserted in the opening of the same lock metal fitting as the lock metal fitting 28 shown in FIG. The first lock portion and the second lock portion are formed in parallel to each other with a predetermined interval.

  Further, a plurality of openings are formed at positions on the upper surface portion adjacent to the pressing spring and directly above the contact terminals. A bent piece that protrudes toward the card accommodating portion is formed at the periphery of each opening. The bent piece abuts against the end of the inserted SD card SDC, so that the SD card SDC is erroneously inserted into the card slot 42CS from the end on the direction opposite to the end on the normal insertion direction. Thus, damage to the contact terminal due to so-called reverse insertion is avoided.

  In addition, as shown in an enlarged view in FIG. 9B, a protrusion piece 40T is provided at a position adjacent to the pressing piece 10FC on the upper surface portion of the cover member 40 and facing the vicinity of the card slot 42CS. The protruding piece 40T is formed by being bent substantially perpendicular to the upper surface so that a part of the cover member 40 protrudes by a predetermined length toward the notch 42LWa of the side wall 42LW. The protruding piece 40T restricts so-called wrong insertion of the reverse side of the card at a position in the vicinity of the card slot 42CS, in which the SD card SDC is inserted with the contact pad facing the bottom surface of the base member 42. Further, since the protruding piece 40T is formed of a thin metal material, the SD card SDC is reliably prevented from being erroneously inserted without being easily bent. At that time, the user will easily notice the wrong insertion of the card in the reverse side immediately after inserting the card into the card slot 42CS.

  On the other hand, as shown in FIGS. 4A to 4D, when the SD card SDC is inserted in the reverse insertion posture, the SD card SDC passes below the protruding piece 40T and is inserted to a proper position. .

  In the case of the cover member 10 and the base member 12 in the example shown in FIG. 1, for example, as shown in FIGS. 10 (A) and (B), if the SD card SDC is inserted by mistake, The write protect button SDB of the SD card SDC may be moved against the user's intention by being engaged with the end portion of the side wall 12LW.

  However, in the example shown in FIGS. 9A and 9B, even if the SD card SDC is inserted in the wrong direction by mistake, the leading edge of the SD card SDC is placed in the card slot 42CS. Immediately after the insertion, the contact operation with the projecting piece 40T restricts further insertion operation, and there is no possibility that the write protect button SDB of the SD card SDC interferes with the end of the side wall 12LW. Undesirable movement is avoided.

  In such a configuration, when the SD card SDC and the HG-Duo card 22 are attached to and detached from the card housing portion 42A, the same effects as the first embodiment shown in FIG. The duplicate description is omitted.
