  However, the conventional card connector as described above has a problem that it is impossible to prevent erroneous insertion of the card, although simultaneous mounting of the first card and the second card is prevented. That is, the second card is formed so as to be narrower than the first card and has a size that can be inserted into the first insertion slot corresponding to the first card. There was a risk of being inserted into the insertion slot.

  The present invention has been made in view of such circumstances, and a card connector that prevents simultaneous insertion of a plurality of cards and prevents erroneous insertion of a card into an insertion slot that is incompatible with the card. The purpose is to provide.

  A card connector according to the present invention includes a housing in which a first insertion slot corresponding to a first card and a second insertion slot corresponding to a second card having a narrower plate thickness than the first card are formed. A shutter member that opens and closes the first insertion slot, and when the first card is not inserted into the first insertion slot, the shutter member is locked in a closed state, and the first card A lock member that is driven by the first card to release the lock of the shutter member and restricts the insertion of the second card into the second insertion port when inserted into the first insertion port; It is provided with.

  According to this configuration, when the first card is inserted into the first insertion slot first, insertion of the second card into the second insertion slot is restricted by the lock member. Wearing can be prevented. Further, when the first card is not inserted, the shutter member is locked in the closed state with the first insertion slot closed, so that the second card can be inserted into the first insertion slot. Incorrect insertion into the first insertion slot of the second card can be prevented.

  In the card connector according to the present invention, the lock member restricts unlocking of the shutter member when the second card is inserted into the second insertion slot.

  According to this configuration, when the second card is first inserted into the second insertion slot, the unlocking of the shutter member by the lock member is restricted, so that the first card is inserted into the first insertion slot. Card insertion is restricted and simultaneous card insertion can be prevented.

A holding portion that is swingably held between an unlockable position that is separated from the protrusion and an unlocking restriction position that engages with the engaging protrusion, and the distal end portion of the shutter member has the second portion When the card is not inserted into the second insertion slot, the card is located at the unlockable position in a state of protruding from the first insertion slot to the second insertion slot, and the second card At the time of insertion into the insertion slot, the second card abuts on the second card and swings to the unlocking restriction position, and retreats to the first insertion slot side to allow insertion of the second card. It is characterized by doing.

  According to this configuration, when the second card is not inserted into the second insertion slot, the distal end portion of the shutter member is positioned at the unlockable position, so that the first card is inserted into the first insertion slot. When the second card is inserted into the second insertion slot, the tip of the shutter member that protrudes from the second insertion slot is pushed by the second card and engages with the engagement protrusion. Thus, unlocking is restricted. Therefore, when the second card is first inserted into the second insertion slot, the unlocking of the shutter member by the lock member is restricted, so the insertion of the first card into the first insertion slot is restricted. Thus, simultaneous card insertion can be prevented.

  According to the present invention, in the card connector, the first insertion port and the second insertion port are adjacent to each other in the thickness direction, and the lock member is provided on the outer side in the width direction of the second insertion port. It is characterized by that.

  According to this configuration, it is possible to reduce the size of the apparatus by disposing the lock member in the surplus space resulting from the difference in width between the first insertion port and the second insertion port in the housing.

  In the card connector according to the present invention, a pair of the locking members are provided apart from the width of the second card.

  According to this configuration, since the pair of locking members are not driven simultaneously by the second card, it is possible to prevent the shutter member from being unlocked by the second card, and the first insertion port of the second card. It is possible to reliably prevent erroneous insertion into the.

  In the card connector according to the present invention, in the closed state, the shutter member is inclined to the second insertion port side in the insertion direction and locked to the lock member.

  According to this configuration, when the second card comes into contact with the shutter member, the second card can be guided to the second insertion slot.

  According to the present invention, it is possible to prevent simultaneous insertion of a plurality of cards, and it is possible to prevent erroneous insertion of cards into an insertion slot that is incompatible with the cards.

It enters the formed escape groove 68 and moves to the second insertion port 12. The insertion prevention unit 67 moved to the second insertion slot 12 prevents the small card 75 from being inserted into the second insertion slot 12.

  With reference to FIG. 4 and FIG. 5, the simultaneous mounting preventing structure and the erroneous mounting preventing structure by the card connector will be described. 4A and 4B are explanatory diagrams when the large card of the card connector according to the embodiment of the present invention is inserted. FIG. 4A is an initial state before insertion, FIG. 4B is an insertion start state, and FIG. Each completed state is shown. FIGS. 5A and 5B are explanatory diagrams when the small card of the card connector according to the embodiment of the present invention is inserted, in which FIG. 5A is an initial state before insertion, FIG. 5B is an insertion start state, and FIG. Each completed state is shown.

  Initially, with reference to FIG. 4, the simultaneous mounting preventing structure and the erroneous mounting preventing structure of the large card 71 will be described. As shown in FIG. 4A, in the initial state, the pair of locking members 7 are pushed upward by the urging force of the winding spring 62, and the shutter member 5 is locked in the closed state. At this time, the shutter member 5 is urged forward by the winding spring 52, and the distal end portion 53 is pressed against the unlockable position of the holding portion 65. In this state, since the size of the second insertion slot 12 is smaller than that of the large card 71, the large card 71 is not erroneously inserted into the second insertion slot 12.

  From this initial state, as shown in FIG. 4B, when the large card 71 is inserted into the first insertion slot 11, the inclined surfaces 64 of the pair of lock members 7 come into contact with the front end portion of the large card 71. . When the inclined surfaces 64 of the pair of lock members 7 are pressed by the front end portion of the large card 71, the lock member 7 is pushed down against the urging force of the winding spring 62, and the front end portion 53 of the shutter member 5 is moved to the lock member 7. Is removed from the holding portion 65 and the lock is released. At this time, the insertion preventing portion 67 moves from the first insertion port 11 to the second insertion port 12 by pushing down the lock member 7.

  When the large card 71 is further inserted into the first insertion slot 11, the front end portion of the large card 71 is brought into contact with the shutter member 5. When the shutter member 5 is pressed by the front end portion of the large card 71, the shutter member 5 is opened rearward against the urging force of the winding spring 52, and the first insertion port 11 is opened.

  When the large card 71 is further inserted into the first insertion slot 11 from this state, the socket portion of the large card 71 is engaged with the pin terminal 15 as shown in FIG. Is attached to the card connector 1. At this time, since the insertion blocking portion 67 of the pair of lock members 7 is located at the second insertion slot 12, insertion of the small card 75 into the second insertion slot 12 is blocked. As described above, when the large card 71 is mounted first, the small card 75 is prevented from being simultaneously mounted by the insertion blocking portion 67 of the lock member 7.

  Next, with reference to FIG. 5, the simultaneous mounting preventing structure and the erroneous mounting preventing structure of the small card 75 will be described. As shown in FIG. 5A, in the initial state, the pair of locking members 7 are pushed upward by the urging force of the winding spring 62, and the shutter member 5 is locked in the closed state. At this time, the shutter member 5 is urged forward by the winding spring 52, and the distal end portion 53 is pressed against the unlockable position of the holding portion 65. Further, the distal end portion 53 of the shutter member 5 slightly protrudes from the first insertion port 11 to the second insertion port 12 side.

  In this initial state, the size of the first insertion slot 11 is sufficiently larger than that of the small card 75, but the small card 75 is inserted into the first insertion slot 11 because the shutter member 5 is locked in the closed state. There is no mistaken insertion. In this case, since the pair of lock members 7 are provided outside the second insertion port 12 that is separated from the width of the small card 75, the pair of lock members 7 can be simultaneously driven by the small card 75. Can not. Therefore, erroneous insertion of the small card 75 into the first insertion slot 11 is reliably prevented.

  In this initial state, the shutter member 5 is held by the lock member 7 so as to be inclined downward in the insertion direction. In this case, when trying to insert the small card 75 into the first insertion slot 11, the small card 75 comes into contact with the shutter member 5 and is guided to the second insertion slot 12 by the inclination of the shutter member 5.

  When the small card 75 is inserted into the second insertion slot 12 from this initial state as shown in FIG. 5B, the shutter member protrudes from the front end portion of the small card 75 to the second insertion slot 12 side. 5 end portions 53 abut. When the front end portion 53 of the shutter member 5 is pressed by the front end portion of the small card 75, the front end portion 53 of the shutter member 5 is moved to the unlocking restriction position of the holding portion 65 against the urging force of the winding spring 52. . And the front-end | tip part 53 of the shutter member 5 is engaged with the engagement protrusion 66 in a lock release control position, and depression of the lock member 7 is controlled.

  From this state, when the small card 75 is further inserted into the second insertion slot 12, the pad of the small card 75 comes into contact with the contact terminal 17 as shown in FIG. The connector 1 is attached. At this time, even when the large card 71 comes into contact with the contact portion 63 of the lock member 7 due to the engagement between the front end portion 53 of the shutter member 5 and the engagement protrusion 66 of the lock member 7, the lock release is not performed. Be regulated. As described above, when the small card 75 is mounted first, the shutter member 5 keeps the closed state regardless of the insertion of the large card 71 into the first insertion slot 11, and the large card 71 is simultaneously mounted. Is prevented.

  As described above, the card connector 1 prevents the large card 71 and the small card 75 from being mounted simultaneously, and prevents the small card 75 from being erroneously inserted into the first insertion slot 11 for the large card 71. Yes. Further, since the shutter member 5 closes the first insertion slot 11 on the front surface of the card connector 1, it is inserted into the first insertion slot 11 when the small card 75 is likely to be inserted by mistake. The insertion of the small card 75 can be prevented without causing it. With this configuration, it is possible to make the user clearly recognize erroneous insertion. Further, since the insertion preventing portion 67 is provided in the lock member 7, it is possible to prevent the small card 75 from being inserted into the second insertion slot 12 in conjunction with the driving of the lock member 7.

  With reference to FIG. 6 and FIG. 7, the card discharge structure by the card connector will be described. FIG. 6 is an explanatory diagram of a large card discharging structure of the card connector according to the embodiment of the present invention. 7A and 7B are explanatory diagrams of a small card ejection structure of the card connector according to the embodiment of the present invention, wherein FIG. 7A is a top view and FIG. 7B is a rear view. In FIG. 6 and FIG. 7A, the outline of the lid is indicated by a broken line for convenience of explanation.

  First, the discharging structure of the large card 71 will be described with reference to FIG. As shown in FIG. 6, the discharge mechanism 9 has a main drive arm 41 and a driven arm 42 that are rotatably supported by the support portions 36 and 37 of the lid 3, and the driven arm 42 is connected via a claw piece 45. It is configured to be interlocked with the main arm 41. The main arm 41 and the follower arm 42 are provided with contact pieces 46 and 47 that contact the large card 71. The contact pieces 46 and 47 are directed from the first mounting space to the second mounting space. It extends downward.

  When the large card 71 is attached to the card connector 1, the main arm 41 and the driven arm 42 are rotated backward by the large card 71 via the contact pieces 46 and 47. When the push button 39 of the operation unit 8 is pushed in the direction of the arrow in the state where the large card 71 is mounted, the main arm 41 rotates forward and the driven arm 42 rotates forward. As the main drive arm 41 and the follower arm 42 rotate forward, the large card 71 is pushed out in the discharge direction by the contact pieces 46 and 47 and discharged.

  Next, the discharge structure of the small card 75 will be described with reference to FIG. As shown in FIGS. 7A and 7B, the discharge mechanism 9 has a discharge plate 48 that is driven in conjunction with the main drive arm 41 and the driven arm 42. The discharge plate 48 extends in the width direction and is slidably disposed on the bottom surface side of the connector main body 2. A pair of abutment pieces 49 that abut against the small card 75 are provided in an intermediate portion in the extending direction of the discharge plate 48. Further, the discharge plate 48 is in contact with the contact pieces 46 and 47 of the main driving arm 41 and the driven arm 42 at the rear.

  When the small card 75 is attached to the card connector 1, the main arm 41 and the driven arm 42 are rotated rearward by the small card 75 via the discharge plate 48. When the push button 39 of the operation unit 8 is pushed in the direction of the arrow in the state where the small card 75 is mounted, the main arm 41 rotates forward and the driven arm 42 rotates forward. As the main drive arm 41 and the follower arm 42 rotate forward, the discharge plate 48 is pushed out in the discharge direction by the contact pieces 46 and 47. When the discharge plate 48 is pushed out, the small card 75 is pushed out in the discharge direction by the pair of contact pieces 49 and discharged.

  As described above, the discharge mechanism 9 in the present embodiment also serves as a discharge mechanism for the large card 71 and a discharge mechanism for the small card 75, and the discharge operation for the large card 71 and the small card 75 are driven by the discharge mechanism 9. Are simultaneously discharged. Therefore, if the large card 71 and the small card 75 are mounted at the same time, there is a problem that the large card 71 and the small card 75 are simultaneously discharged. In the card connector 1 according to the present invention, since only one of the large card 71 and the small card 75 can be mounted, the problem of simultaneous ejection does not occur. As described above, the present invention is particularly effective for a card connector having a discharge mechanism for simultaneously discharging two types of cards.

  As described above, according to the card connector 1 according to the present embodiment, when the large card 71 is first inserted into the first insertion slot 11, the small card 75 is inserted by the insertion blocking portion 67 of the lock member 7. Since the insertion into the second insertion slot 12 is restricted, it is possible to prevent the large card 71 and the small card 75 from being mounted simultaneously. Further, when the small card 75 is first inserted into the second insertion slot 12, the unlocking of the lock member 7 with respect to the shutter member 5 is restricted, and the insertion of the large card 71 into the first insertion slot 11 is restricted. Therefore, simultaneous mounting of the large card 71 and the small card 75 can be prevented. In addition, when the large card 71 is not inserted, the shutter member 5 is locked in the closed state with the first insertion slot 11 closed, so that the small card 75 can be prevented from being erroneously inserted into the first insertion slot 11. It becomes possible.

  In the embodiment described above, the large card is described as a CF card and the small card as an SD card. However, the present invention is not limited to this configuration. The present invention is applicable to cards of different standards in which the other card is narrow and thin with respect to one card.

  In the above-described embodiment, the shutter member is locked at two positions in the pair of lock members. However, the present invention is not limited to this configuration. As long as the shutter member can be locked, the shutter member may be locked by one locking member, or the shutter member may be locked by three or more locking members.

  Further, in the above-described embodiment, the shutter member is formed in a plate shape, but is not limited to this configuration. What is necessary is just to be able to prevent the insertion of the small card into the first insertion slot. For example, the small card may be formed with a slit through which the small card cannot be inserted, or may be formed in a frame shape.

  In the above-described embodiment, the lock member unlocking is regulated by the engagement between the front end of the shutter member and the engagement protrusion of the lock member. However, the present invention is not limited to this configuration. Any structure that can regulate the unlocking of the lock member when the small card is inserted into the second insertion slot may be used. For example, a member that regulates the unlocking of the shutter member may be provided separately from the lock member.

  In the above-described embodiment, the insertion slot for large cards is formed on the upper side and the insertion slot for small cards is formed on the lower side. However, the present invention is not limited to this configuration. A configuration may be adopted in which an insertion port for a small card is formed on the upper side and an insertion port for a large card is formed on the lower side. In this case, the shutter member is configured to be able to open downward, and the lock member is configured to move up in response to insertion of a large card.

  In the above-described embodiment, the front end of the shutter member protrudes from the first insertion port to the second insertion port. However, the amount of protrusion is determined by moving the shutter member to the unlocking restriction position. Sometimes, it is sufficient to allow insertion of the small card into the second insertion slot. Further, it is not necessary that all the extending direction of the tip end portion of the shutter member protrudes, and it is sufficient that at least a part protrudes.

  In the above-described embodiment, the shutter member is inclined downward along the insertion direction and held by the lock member. However, the present invention is not limited to this configuration. In the state where the shutter member is locked in the closed state, it is not necessary to incline if the guide to the second insertion slot of the small card is unnecessary.

  In the above-described embodiment, the present invention is applied to a card connector having a push-button type discharging structure, but is not limited to this configuration. Any card connector that can selectively mount a plurality of cards of different sizes may be used. For example, the present invention may be applied to a card connector having a push-push type discharging structure.

  The embodiment disclosed this time is illustrative in all respects and is not limited to this embodiment. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims for patent.

  As described above, the present invention has an effect of preventing simultaneous insertion of a plurality of cards and preventing erroneous insertion of a card into an insertion slot that is incompatible with the card. This is useful for a card connector having a structure for preventing simultaneous mounting of a plurality of different cards.
