Engagement lock parts 20 and 20 are constituted by an elastic piece formed by cutting and raising the part of cover member 2b (metal plate) facing claw parts 99a and 99a downward, and due to its elastic force The engagement hole 20a at the end is always urged in a direction to engage with the claw 99a.

  Note that the claw portions 99a and 99a and the engagement lock portions 20 and 20 on both sides constituting the shutter lock mechanism are separated from each other by a distance L larger than the width dimension W2 (see FIG. 2) of the second card C2. At the same time, they are separated from each other by a distance L shorter than the width dimension W1 (see FIG. 7) of the first card C1. The engaging position between the claw portions 99a and 99a and the engaging lock portions 20 and 20 is such that the height from the placement surface of the second storage portion 3b on which the second card C2 is placed is the second. It is set larger than the thickness of the card C2. Each engagement lock portion 20 is obliquely downward from the cover member 2b toward the rear end wall 21 of the housing body 2a so as to be in contact with the first card C1 inserted into the first storage portion 3a. It extends and protrudes into the insertion path of the first storage portion 3a.

  Further, on the back side of the storage unit 3, more precisely, the back side of the first storage unit 3a, an elastic piece that contacts the external connection terminal of the first card C1 inserted into the first storage unit 3a. Are arranged in parallel. Further, in the substantially intermediate portion in the longitudinal direction of the storage unit 3, more precisely, in the second storage unit 3b, the external connection terminal of the second card C2 inserted into the second storage unit 3b is contacted. A plurality of connector terminals 5b made of elastic pieces are arranged in parallel. In this case, the connector terminals 5a and 5b are electrically connected to corresponding circuit patterns on an external circuit board such as an electronic device. In order to electrically detect that the card C is located at a predetermined storage position (therefore, the external connection terminal of the first or second card C1, C2 and the connector terminal 5a, 5b are in contact). It is preferable that the card detecting means is provided.

  The housing body 2a has side walls 22a and 22b on both sides. In this case, the inner surface on the front end side of the side wall 22a on one side is formed as a stepped surface that forms a step in the vertical direction, and the inner surface 6a on the upper side facing the first storage portion 3a is the first inner surface 6a. Formed as a first guide surface for guiding one side edge of the first card C1 inserted into the storage portion 3a, and a lower inner surface 6b facing the second storage portion 3b It is formed as a second guide surface for guiding one side edge portion of the second card C2 inserted into the second storage portion 3b.

  A slide member 12 that is movable in the insertion / ejection direction of the card C with respect to the housing 2 is attached to the housing body 2a. In this case, the slide member 12 is slidably disposed along the other side wall 22b of the housing body 2a.

  The slide member 12 is made of an insulating material such as synthetic resin, and is engaged with a guide rail extending along the insertion / ejection direction of the card C, for example, and moves along the guide rail. Yes. Specifically, the slide member 12 has the first or second card C1 or C2 introduced into the storage unit 3 due to movement restriction caused by engagement between a heart-shaped cam groove 80 and a lock pin 82, which will be described later. The card C is the housing so that the external connection terminal is electrically connected to the connector terminal 5a or 5b (position shown in FIGS. 6 and 14 described later) and the card C can be inserted into and removed from the housing 2. 2 can be moved between the discharge positions pushed out to the outside (positions shown in FIGS. 1 to 4 and FIGS. 8 to 11).

  The slide member 12 is located on the side of the housing main body 2a and extends in the front-rear direction (in the insertion / ejection direction of the card C), and the main body 12a protrudes into the first storage portion 3a. A main body portion 12a that is formed integrally with the rear end portion and protrudes into the second storage portion 3b, and a first pressing action portion 12b having a substantially triangular shape that can come into contact with the rear end of the first card C1. And a substantially rectangular second pressing portion 12c that can be brought into contact with the rear end of the second card C2.

  The inner surface on the front end side of the main body portion 12a is formed as a stepped surface that forms a step in the vertical direction, and the inner surface 6c on the upper side of the main body portion 12a facing the first storage portion 3a is described above. Together with the first guide surface 6a of the housing body 2a, it is formed as a third guide surface 6c for guiding the other side edge portion of the first card C1 inserted into the first storage portion 3a. Further, the lower inner surface 6d of the main body 12a facing the second storage portion 3b is inserted into the second storage portion 3b together with the second guide surface 6b of the housing main body 2a described above. It is formed as a fourth guide surface 6d for guiding the other side edge of the card C2.

  Further, the first and second pressing action portions 12 b and 12 c are adapted to transmit force accompanying movement between the card C and the slide member 12 by contacting the corresponding card C.

  The slide member 12 is constantly urged toward the discharge position by a compression spring as urging means (not shown). In this case, the rear end of the compression spring is supported by a spring support portion protruding from the inner surface of the rear end wall 21 of the housing main body 2a, and the front end side of the compression spring is the main body portion 12a of the slide member 12. Is supported by a spring support portion projecting from the rear end surface of the rear end surface.

  Further, the card connector device 1 of the present embodiment has a slide lock mechanism that locks the slide member 12 at the connection position. This slide lock mechanism has a heart-shaped cam groove 80 formed on the upper surface of the front end side of the main body 12 a of the slide member 12, and a lock pin 82 that engages with the cam groove 80.

  One end 82a of the lock pin 82 is supported by the front side end of the housing body 2a, and the other end 82b is slidably engaged with the cam groove 80. The cover member 2 b of the housing 2 is provided with a pressing portion 103 that presses the lock pin 82 and holds the engagement state between the other end 82 b of the lock pin 82 and the cam groove 80. In this case, it is preferable that the pressing portion 103 is made of an elastic piece formed by cutting a portion of the cover member 2b (metal plate) facing the lock pin 82 downward.

  As clearly shown in FIG. 6 and the like, the heart-shaped cam groove 80 is formed as an annular groove composed of a plurality of inclined surfaces and planes. Specifically, the cam groove 80 is located at the center of the rear end locking groove portion 80 a that defines the discharge position of the slide member 12 and the front end side of the cam groove 80 and defines the connection position of the slide member 12. A pair of first and second sliding groove portions 80c and 80d extending along a substantially heart-shaped outer shape so as to connect the recessed front end locking groove portion 80b, the rear end locking groove portion 80a and the front end locking groove portion 80b. Including. Further, as will be described later, the cam groove 80 holds the slide member 12 at the discharge position when the other end 82b of the lock pin 82 is engaged with the rear end engaging groove 80a, and the front end engaging groove portion thereof. When the other end 82b of the lock pin 82 is engaged with 80b, the slide member 12 is held (locked) at the connection position.

  Next, the operation of the card connector device 1 having the above configuration will be described with reference to FIGS.

  First, with reference to FIGS. 2 to 6, a description will be given of a case where a short second card C <b> 2 having a narrow width is inserted into the housing 2. FIG. 2 shows a state in which the slide member 12 is positioned at the discharge position by the urging force of the compression spring. In this state, the other end 82 b of the lock pin 82 is engaged with the rear end engagement groove 80 a of the cam groove 80. From this state, when the second card C2 is pushed (inserted) into the lower second storage portion 3b through the card insertion slot 4, the second card C2 has both side edges as shown in FIG. While being guided by the second and fourth guide surfaces 6b and 6d, the rear end abuts against the second pressing portion 12c without interfering with the shutter member 99. This state is shown in FIG.

  If the second card C2 is mistakenly inserted into the upper first storage portion 3a, the rear end of the second card C2 hits the shutter member 99. At this time, the width dimension W2 of the second card C2 is smaller than the separation distance L between the engagement positions (positions where the claw 99a and the engagement lock 20 are engaged) on both sides of the shutter lock mechanism. The engagement state of both sides of the shutter lock mechanism is not released by the insertion of the second card C2, and therefore the shutter member 99 is not opened, and the second card C2 can be further inserted into the housing 2. Can not. That is, erroneous insertion (erroneous mounting) of the second card C2 is prevented.

  Further, when the second card C2 is further inserted into the second storage portion 3b from the contact state as shown in FIG. 4, as shown in FIG. The slide member 12 moves to the connection position against the urging force of the compression spring by the pushing force of the acting second card C2. Further, with this movement, the other end 82 b of the lock pin 82 traces the first sliding groove portion 80 c of the cam groove 80. When the slide member 12 reaches the connection position by such movement, the other end 82b of the lock pin 82 is engaged with the recessed front end engagement groove 80b in the center of the cam groove 80, and the slide member 12 is attached to the housing 2. It is positioned and fixed with respect to it. That is, the slide member 12 is locked at the connection position. This state is shown in FIG. In the state shown in FIG. 6, the external connection terminal of the second card C2 is brought into contact with the corresponding connector terminal 5b.

  In the state shown in FIG. 6, when the second card C2 is pulled out from the housing 2, the second card C2 is once pushed into the housing 2, and the slide member 12 is resisted against the urging force of the compression spring. Slide further into the back of the housing 2. As a result, the locked state between the other end 82b of the lock pin 82 and the front end locking groove 80b of the cam groove 80 is released. Therefore, when the pressing force on the second card C2 and the slide member 12 is released in this state, the second card C2 and the slide member 12 are moved to the discharge position by the urging force of the compression spring. By this movement, the other end 82 b of the lock pin 82 traces the second sliding groove 80 d of the cam groove 80, and accordingly, the second card C 2 is also pushed out of the housing 2 through the card insertion slot 4. Thereafter, when the other end 82b of the lock pin 82 is engaged with the rear end engaging groove 80a of the cam groove 80 and the slide member 12 is positioned at the discharge position, the state shown in FIG. 4 is restored.

  Next, a case where the first wide and thick first card C1 is inserted into the housing 2 will be described with reference to FIGS. 7, 8, and 15 (a) show a state in which the slide member 12 is positioned at the discharge position by the urging force of the compression spring. In this state, as described above, the other end 82b of the lock pin 82 is engaged with the rear end engagement groove 80a of the cam groove 80. When the first card C1 is pushed (inserted) into the upper first storage portion 3a through the card insertion slot 4 from this state, both side edges of the first card C1 are as shown in FIG. While being guided by the first and third guide surfaces 6a and 6c, it proceeds toward the first storage portion 3a, and its upper surface constitutes a shutter lock mechanism as shown in FIG. The engagement lock portions 20 and 20 on both sides come into contact with each other, and the engagement lock portion 20 is lifted against its downward elastic force. Thereby, as shown in FIG. 15C, the engagement state between the engagement lock portion 20 and the claw portion 99a of the shutter member 99 is released. Therefore, when the first card C1 is further pushed into the first storage portion 3a as it is, the shutter member 99 starts to rotate downward as shown in FIG. 10, and the shutter member 99 is completely rotated. At the time, an insertion path into the first storage portion 3a is secured (opened) (see FIG. 11). When the first card C1 is further pushed into the first storage portion 3a as it is, the rear end of the first card C1 comes into contact with the first pressing portion 12b. This state is shown in FIG.

  If the first card C1 is erroneously inserted into the lower second storage portion 3b, the rear end of the first card C1 hits the front end surface of the housing body 2a. This is because the distance between the guide surfaces 6b and 6d (the lower opening of the card insertion slot 4 leading to the second storage portion 3b) is set smaller than the width dimension W1 of the first card C1. is there. That is, erroneous insertion (erroneous mounting) of the first card C1 is reliably prevented at the stage before insertion into the housing 2 due to the difference in the size of the upper and lower openings of the card insertion slot 4.

  Further, when the first card C1 is further inserted into the first storage portion 3a from the contact state as shown in FIG. 12, as shown in FIG. The slide member 12 moves to the connection position against the urging force of the compression spring by the pushing force of the acting first card C1. Further, with this movement, the other end 82 b of the lock pin 82 traces the first sliding groove portion 80 c of the cam groove 80. When the slide member 12 reaches the connection position by such movement, the other end 82b of the lock pin 82 is engaged with the recessed front end engagement groove 80b in the center of the cam groove 80, and the slide member 12 is attached to the housing 2. It is positioned and fixed with respect to it. That is, the slide member 12 is locked at the connection position. This state is shown in FIG. In the state shown in FIG. 14, the external connection terminal of the first card C1 is in contact with the corresponding connector terminal 5a.

  In the state shown in FIG. 14, when the first card C1 is pulled out from the housing 2, the first card C1 is once pushed into the housing 2, and the slide member 12 is resisted against the urging force of the compression spring. Slide further into the back of the housing 2. As a result, the locked state between the other end 82b of the lock pin 82 and the front end locking groove 80b of the cam groove 80 is released. Therefore, when the pressing force on the first card C1 and the slide member 12 is released in this state, the first card C1 and the slide member 12 are moved to the discharge position by the urging force of the compression spring. By this movement, the other end 82 b of the lock pin 82 traces the second sliding groove 80 d of the cam groove 80, and accordingly, the first card C 1 is also pushed out of the housing 2 through the card insertion slot 4. Thereafter, when the other end 82b of the lock pin 82 is engaged with the rear end engaging groove 80a of the cam groove 80 and the slide member 12 is positioned at the discharge position, the state shown in FIG. 12 is restored.

  As described above, according to the card connector device 1 of the present embodiment, the shutter member 99 that blocks the card insertion path into the first storage portion 3a and the lock that locks the shutter member 99 in the closed position. Since the mechanisms 20 and 99a are provided and the locked state by the lock mechanisms 20 and 99a is released by the insertion of the first card C1, the first card C1 into the first storage portion 3a is provided. It is possible to prevent erroneous insertion of the second card C2 into the first storage portion 3a without hindering the insertion of the card. Moreover, since the part 20 of the lock mechanism is formed by bending a part of the cover member 2b, the existing parts can be used effectively and the number of parts can be reduced.

  In the card connector device 1 of the present embodiment, the engagement lock portion (engagement piece) 20 constituting the lock mechanism is in contact with the first card C1 inserted into the first storage portion 3a. Thus, the engagement with the shutter member 99 (claw 99a) is released. In this way, the first card C1 can be ejected from the first storage portion 3a by the frictional force accompanying the contact between the shutter member 99 and the first card C1, so that the brake can be applied. The discharging operation of one card C1 can be performed safely and smoothly.

  Further, in the card connector device 1 of the present embodiment, the shutter member 99 is arranged so as not to block the insertion path of the card C into the second storage portion 3b. Therefore, the insertion path of the second card C2 with respect to the second storage unit 3b is reliably ensured. That is, according to the configuration of the present embodiment, the second card C2 is allowed to be inserted into the second storage portion 3b while being prevented from being inserted into the first storage portion 3a by the shutter member 99, Since the first card C1 itself is allowed to be inserted into the first storage portion 3a by releasing the locked state of the shutter member 99 in the closed position, the first card C1 is inserted into the first card C1. It becomes possible to selectively insert the corresponding first and second storage portions 3a and 3b.

  Further, in the card connector device 1 of the present embodiment, the engagement lock portion 20 engages with the shutter member 99 (claw portion 99a) on both sides along the direction orthogonal to the card insertion direction, and the engagement on both sides thereof. The distance L between the joint portions is smaller than the dimension (specifically, the width dimension W1) of the first card C1 along the direction orthogonal to the card insertion direction, and is the first along the direction orthogonal to the card insertion direction. The size is set to be larger than the size of the second card C2 (specifically, the width size W2). Therefore, the engagement state on both sides of the shutter member 99 and the engagement lock portion 20 can be released only by the first card C1. Therefore, the selective insertion of the first and second cards C1 and C2 into the first and second storage portions 3a and 3b can be ensured.

  The present invention is not limited to the embodiment described above, and can be implemented with various modifications. For example, in the above embodiment, the engagement lock portion 20 is displaced in contact with the upper surface of the first card C1, so that the engagement state between the engagement lock portion 20 and the claw portion 99a is released. The engagement state between the engagement lock portion 20 and the claw portion 99a may be released by the displacement of the engagement lock portion 20 in contact with the lower surface or side surface of the first card C1. Moreover, in the said embodiment, although the engagement part of the lock mechanism is provided in the both sides along the width direction of the card | curd C, the engagement part of the lock mechanism is provided in the both sides along the thickness direction of the card | curd C. May be. Also in this case, the engagement state of the lock mechanism needs to be released only by the first card C1. This configuration is particularly useful in a structure in which two types of cards having different thicknesses are selectively inserted. In addition, the size, the number, the mounting mode, and the like of the constituent members can be variously changed and implemented without departing from the scope of the present invention.

  The present invention inserts and ejects a card-like medium such as a storage medium to and from various portable information terminals such as a mobile phone and a PC, a digital camera, or an electronic device such as a digital AV device. The present invention can be applied to a card connector device for achieving an electrical connection between an external connection terminal provided on a medium and an electronic circuit formed on a circuit board of the electronic device.
