  The present invention relates to a card connector to which a card in which an electronic circuit such as a memory chip is housed in a small and thin case, and more particularly to a card connector that can easily position a loaded card in a housing. .

  Digital cameras, digital video cameras, personal computers, and the like are used with a small and thin electronic function card called a memory card. In this electronic function card, an IC chip that functions as a memory chip, a memory controller, or the like is housed in a small and thin case (sometimes referred to as a housing) formed of a synthetic resin material. A plurality of external connection portions that are electrically connected to an internal electronic circuit are provided on the back surface of the case.

  The electronic function card is used by being mounted on a card connector, and the card connector is provided with a plurality of connection terminals that individually contact a plurality of external connection portions provided on the electronic function card.

  As the card connector, a slot-in type in which an electronic function card is inserted in a direction parallel to the front surface and the back surface thereof toward a slit-shaped insertion opening that opens in the housing body, and the following Patent Document 1 and Patent Document 2, for example: Open / close type that attaches the electronic function card to the housing body by inserting the electronic function card into the open lid and closing the lid toward the housing body together with the electronic function card Is known. The open / close type, unlike the slot-in type, does not require a lock mechanism or a card ejection mechanism inside the housing body, and can be configured with a relatively simple structure at a low cost and in a small size. .

  In the invention described in the following Patent Document 1, when the card is loaded into the base member, the concave portions formed on the left and right side surfaces of the card are aligned with the left and right positioning protrusions of the base member, and the card is When pushed downward (bottom plate side), the inclined guide surface of each positioning projection slides into contact with the lower edge of the recess, smoothly guides the card downward, and each positioning projection fits into each recess. As a result, the card is positioned.

  However, in those described in Patent Document 1 and Patent Document 2, the locking recesses formed on the left and right side surfaces of the card as shown in FIG. 1 of Patent Document 1 and FIG. It is impossible to lock any card other than the type of card that penetrates the card. That is, there is a problem that the card cannot be held for a type of card in which the recess has only a depth of about half the thickness direction.

  In addition, since the cards described in Patent Documents 1 and 2 cannot hold the card in an appropriate position unless the opening / closing cover is closed, the unstable state of the card is continued when the opening / closing cover is opened. There was also a problem that.

  The present invention solves the above-described conventional problems, and a card that can be positioned at an appropriate position in the housing even if the concave portion has only a depth of about half the thickness direction in the plate thickness direction. The purpose is to provide a connector.

The present invention provides a card comprising a housing body on which a card having a recess formed at a predetermined depth from a surface in a plate thickness direction orthogonal to the width direction is mounted on at least one side surface in the width direction. In the connector,
The housing body is provided with a positioning mechanism for holding the recess,
The positioning mechanism has an engaging portion that elastically deforms and engages with the concave portion, and the engaging portion engages with the concave portion, thereby preventing the card from coming off in the plate thickness direction. , Positioning in the front-rear direction, which is a direction orthogonal to the width direction and the plate thickness direction, is performed.

  In the card connector according to the present invention, even if the concave portion is a type of card having only about half the depth dimension in the plate thickness direction, the card can be reliably prevented from being detached and positioned in the front-rear direction.

In the above, a housing connected to the housing body is formed, and the housing body is formed with a storage space having an opening on the upper side, and the back surface of the card faces the bottom of the storage space. The lid body is pivotable between an open posture that has a fulcrum between the lid and the housing body and a closed posture that covers the opening, Furthermore, the lid can be set to a locked posture that is locked so as not to move away from the opening by moving in the direction in which the fulcrum moves from the closed posture,
When the card is mounted in the storage space and the engagement portion is engaged with the recess, the lid is locked, so that the engagement state between the engagement portion and the recess is maintained. Those are preferred.

  In the above means, since the movement of the card in the plate thickness direction can be restricted by the lid, the engagement state between the engaging portion on the positioning mechanism side and the concave portion on the card side can be stabilized. In addition, since it is difficult to release the engagement state between the engagement portion and the recess, it is possible to prevent the card from coming off. As a result, the card can be securely held.

  The positioning mechanism includes an elastic portion made of a leaf spring and the engaging portion provided at the tip of the elastic portion, and the back side of the card mounted in the housing body is the engaging portion. It is preferable that the elastic portion is deformed in a retracting direction by contacting the portion, and the engaging portion engages with the concave portion.

  With the above means, the card can be freely inserted and removed with a simple configuration. And since it can form integrally with a leaf | plate spring, the number of partial points can be decreased.

  Further, it is preferable that a pair of concave portions are formed at both edges in the width direction of the card, and a pair of engaging portions corresponding to the concave portions are formed at both ends of the elastic portion.

  In the above means, since both sides of the card can be engaged, the card can be surely positioned.

Further, the pair of engaging portions are provided on the outer side in the width direction corresponding to both side surfaces of the card,
Before the elastic part is deformed, the opposing dimension of the pair of engaging parts is set to the first state having the same or slightly wider dimension than the width dimension between the both side surfaces,
A second state in which the opposing dimension of the pair of engaging parts is narrower than the width dimension between the two side surfaces when the back surface of the card abuts against the elastic part and the elastic part is deformed in the retracting direction. It is preferable to be deformed to engage with the pair of recesses.

  In the above configuration, the elastic body is deformed into the first state and the second state in accordance with the mounting of the card, so that the card can be mounted easily and reliably.

Alternatively, the engaging portion has a locking portion provided at a tip thereof in a state where the elastic portion is embedded in a defect portion formed in both wall portions of the housing body corresponding to both side surfaces of the card. It is supported to be elastically deformable,
The locking portion has an upper slope formed between an intermediate portion and an upper portion in the plate thickness direction, and a lower slope formed between the intermediate portion and the lower portion,
When the card is mounted from above, the edge of the card is brought into contact with the upper slope and the engaging portion is moved away from the card, so that the card can be mounted on the casing body. What is possible is preferred.
Also by the above means, the card can be surely positioned with a simple configuration.

  In the present invention, even when the concave portion is a type of card having only about half the depth dimension in the plate thickness direction, the card can be prevented from being detached and positioned in the front-rear direction.

  Moreover, since it is the structure which engages the recessed part of a card | curd with a simple structure, positioning of a card | curd can be performed reliably.

Are inserted into the guide recesses 28b, 28b on the back side of the casing body 21 through the window 28, respectively. In this state, as shown in FIG. 5A, the lower ends on the outer sides of the second guide portions 64, 64 in the inclined posture are opposed to the retracting portions 28 a, 28 a at the upper position of the window portion 28.

  Further, the front ends of the engaging portions 62, 62 are retracted in the retracting recess 25d formed on the rear side (Y2 side) of the first latching recess 25a of the right side plate 25 of the card connector 20 and on the left side plate 24. Oppositely arranged in the recess 24d.

  The distance LL2 (see FIG. 8A) between the first guide 63 and the first guide 63 on the left and right (both sides in the X direction) of the positioning mechanism 60 is equal to the left and right guide recesses 28b shown in FIG. 6A. It is larger than the dimension WW1 between the front end of the center side with the guide recessed part 28b, and narrower than the dimension WW2 between the side rear end of the guide recessed part 28b and the guide recessed part 28b. For this reason, when the elastic portion 61 is pressed downward in the drawing, the distance LL2 between the first guide portion 63 and the first guide portion 63 is widened, so that the positioning mechanism 60 has a convex arch shape shown in FIG. It is deformed from the (first state) to the linear shape (second state) shown in FIG. Further, when the pressure on the elastic portion 61 is released from this state, the distance dimension LL2 between the first guide portion 63 and the first guide portion 63 is reduced, so that the positioning mechanism 60 has a linear shape ( Deformation from the second state to the convex arch shape (first state) shown in FIG. At this time, the left and right first guide portions 63 and 63 move in the corresponding left and right guide recesses 28b and 28b in the X1 direction and the X2 direction, respectively. Thus, when the positioning mechanism 60 is deformed left and right in the width direction, the first guide portions 63 and 63 are guided by the guide recesses 28b and 28b, so that the deformation operation can be stabilized.

  8A, when the positioning mechanism 60 is deformed from the convex arch shape to the linear shape (second state) shown in FIG. 8B, the lower ends of the second guide portions 64, 64 are retracted. It enters into the sections 28a and 28a.

  The retracting portions 28a, 28a are formed with inclined surfaces that gradually fall outward from the center. For this reason, when the retracting portions 28a and 28a enter from the lower end outside the second guide portions 64 and 64 in the inclined posture, the positioning mechanism 60 reaches the linear shape (second state) shown in FIG. 8B. The upper ends of the second guide portions 64 and 64 are in contact with the inclined lower surfaces forming the retracting portions 28a and 28a. Thereby, even if the positioning mechanism 60 is deformed into a linear shape (second state), it is possible to prevent the displacement in the width direction (X1 and X2 directions) more than necessary.

  Further, when the positioning mechanism 60 is deformed from the convex arch shape shown in FIG. 8 (A) to the linear shape (second state) shown in FIG. 62 and 62 become a vertical attitude | position, and the opposing dimension between the engaging parts 62 and 62 on either side narrows from LL1 to LL1 '.

  9, 10A, and 10B show the structure of the detection mechanism 40. FIG. The detection mechanism 40 is provided with a movable detection member 41. The movable detection member 41 is made of synthetic resin and is an insulator. The movable detection member 41 is integrally formed with a narrow rib 41a protruding rearward (Y2 direction). As shown in FIG. 3 and the like, a guide portion 36a having a narrow width dimension is formed behind the mechanism recess 36 provided in the housing body 21 (in the Y2 direction). The rib 41a is slidably inserted into the guide portion 36a to prevent the movable detection member 41 from rattling in the lateral direction (X direction).

  As shown in FIG. 9, the movable detection member 41 is integrally formed with a pair of sliding protrusions 41b and 41b that protrude rightward (X1 direction). As shown in FIGS. 2 to 4, the storage convex portion 35 is formed with a pair of guide elongated holes 35a, 35a extending in the vertical direction with a space in the front-rear direction (Y direction), and the sliding The protrusions 41b and 41b are inserted into the guide elongated holes 35a and 35a, respectively. Therefore, the movable detection member 41 is supported so as to be movable in the vertical direction without largely shaking in the front-rear direction (Y direction).

  As shown in FIG. 9, the movable detection member 41 is integrally formed with a holding shaft portion 41c, and a ring-shaped holding recess 41d is formed on the outer periphery of the holding shaft portion 41c.

Yes. Therefore, almost no step appears between the fixed contact 43 and the fixed contact 44 and the bottom surface made of synthetic resin.

  The elastic movable contacts 42b and 42c function as a biasing member that always biases the movable detection member 41 upward. As shown in FIG. 10B, when the movable contact member 41 is pushed downward, the elastic movable contact 42b contacts the fixed contact 43, the elastic movable contact 42c contacts the fixed contact 44, and the torsion spring 42 is moved. Thus, the fixed contact 43 and the fixed contact 44 are made conductive. As shown in FIG. 10A, when the movable detection member 41 is lifted by the elastic force of the elastic movable contact 42b and the elastic movable contact 42c, the elastic movable contact 42c is separated from the fixed contact 44, and the fixed contact 43 and the fixed contact 44 are not in contact with each other. It becomes a conductive state.

  On the upper surface of the movable detection member 41, the rear (Y2 direction) portion is a relief surface 45a, and the front (Y1 direction) portion is a pressing surface 45b. The pressing surface 45b protrudes above the flank 45a.

Similarly, a fulcrum shaft 54a projecting in the X2 direction is integrally formed on the base end portion of the support arm portion 54 (not shown).

  As shown in FIG. 5A, a shaft support portion 38 is formed on the outer surface of the right side plate 25 of the housing body 21 at the rear (Y2 direction) portion. The shaft support portion 38 is formed in a convex shape from the outer surface of the right side plate 25 in the X1 direction. The shaft support portion 38 has a support long hole 38a extending in the front-rear direction (Y direction). Similarly, as shown in FIG. 2, a shaft support portion 39 is formed at a position symmetrical to the shaft support portion 38 on the outer surface of the left side plate 24 of the housing body 21. The shaft support portion 39 is formed in a convex shape in the X2 direction, and has a support long hole 39a extending in the front-rear direction.

  A fulcrum shaft 54a provided at the base end portion of the support arm portion 54 is inserted into a support long hole 38a formed in the shaft support portion 38 and is slidable in the front-rear direction (Y direction). ing. Similarly, a fulcrum shaft 55a provided at the base end portion of the support arm portion 55 is inserted into a support long hole 39a formed in the shaft support portion 39 and is slidable in the front-rear direction. Yes.

  At the front portion of the lid 50, the hook portions 56, 56 are bent at right angles on both the right side portion and the left side portion, and hook portions 56a, 56a projecting forward are respectively formed on the hook portions 56, 56. Are provided integrally. On the other hand, a lock projection 37 protrudes from the front outer surface of the right side plate 25 of the housing body 21, and similarly, the lock projection 37 is integrally formed on the front outer surface of the left side plate 24. The lock convex portions 37 and 37 are formed of metal plates protruding from the surfaces of the right side plate 25 and the left side surface 25.

  As shown in FIG. 3, when the lid 50 is rotated to a closed posture covering the opening of the storage space 30 of the housing main body 21 and then the lid 50 is slid forward (Y1 direction), the fulcrum shaft 54a, 55a moves forward (Y1 direction) in the support long holes 38a and 39a, and as shown in FIG. 4, the hook portions 56a and 56a enter below the lock convex portions 37 and 37, and the lid 50 is Become locked. In this locked posture, the lid 50 is locked so as not to rotate in a direction away from the housing body 21.

  As shown in FIG. 1 and the like, a lock leaf spring 57 extending forward is integrally formed from the right side plate 52 bent to the right side portion of the lid 50, and the tip of the lock leaf spring 57 has an X2 direction. A hooking portion 57a that is folded in a mountain shape is formed. As shown in FIGS. 2 and 7, the right side plate 25 of the housing body 21 has a first latching recess 25a and a sliding wall portion 25b located in the rear (Y2 direction) and a front (Y1 direction). A second latching recess 25c is formed.

  As shown in FIG. 3, when the lid 50 is closed in the closed position, as shown in FIG. 11A, the latching portion 57 a formed at the front portion of the lock plate spring 57 is 1 enters the inside of the latching recess 25a. As shown in FIG. 4, when the lid 50 in the closed position is moved toward the forward locked position, the latching portion 57a slides on the outer surface of the sliding wall portion 25b during this time, and FIG. ), When the lid 50 is in the locked position, the latching portion 57a gets over the sliding wall portion 25b and fits into the second latching recess 25c. Therefore, the lid 50 is lightly locked in the locked posture, and the lid 50 in the locked posture can be prevented from inadvertently returning to the Y2 side that is the base side.

  As shown in FIGS. 1 to 4, a detection plate spring 58 is provided on the right side of the lid 50. The detection plate spring 58 is formed integrally with a part of the metal plate constituting the lid 50 and can be elastically deformed.

  The detection plate spring 58 includes an elastic arm portion 58a extending toward the front side, an identification sliding portion 58b formed at the front portion thereof in a mountain fold toward the housing body 21, and a tip of the identification sliding portion 58b. A pressing action part 58c extending to the part is integrally formed.

  As shown in FIGS. 1 to 4 and the like, when no external force is applied, the elastic arm portion 58a is formed in the same plane as the ceiling plate 51 and extends linearly in the Y1 direction with a predetermined width dimension. Yes. Further, the identification sliding portion 58 b protrudes in the direction of the housing body 21 from the ceiling plate 51, and the pressing action portion 58 c is located on substantially the same plane as the ceiling plate 51.

  As shown in FIG. 3, when the lid body 50 is rotated to the closed posture, the elastic arm portion 58 a and the identification sliding portion 58 b face each other directly above the mechanism concave portion 36 of the housing body 21. However, the pressing action portion 58c protrudes in the right direction (X1 direction) from the elastic arm portion 58a and the identification sliding portion 58b, and a part of the pressing action portion 58c is formed on the movable detection member 41 in the mechanism recess 36. It can be opposed to the top.

(Card insertion into the card connector)
Next, a card mounting operation to the card connector 20 shown in the first embodiment will be described.

  2 to 4 show the operation when the first card C1 is inserted into the card connector 20. FIG.

  As shown in FIG. 1 and FIG. 2, the lid 50 is rotated in an open posture with an opening angle of 90 degrees or more with respect to the casing main body 21, and is placed in the storage space 30 of the casing main body 21. Mount the first card C1. The first card C1 is mounted in the storage space 30 with the back surface 1b directed toward the bottom plate 26 of the housing body 21 and the front end 1c directed toward the front side plate 22. When the first card C1 is mounted in a normal posture, each of the plurality of external connection portions 5 provided on the back surface 1b of the first card C1 is provided in the storage space 30 of the housing body 21. Contact the connection terminal 31.

  However, as shown in FIG. 4, the external connection portion 5 provided on the first card C <b> 1 is surely strong against the connection terminal 31 provided on the housing body 21 until the lid 50 is in the locked posture. Since it is not pressed, the contact state of the external connection part 5 and the connection terminal 31 is unstable.

  At this time, the intermediate recesses 8 and 8 of the first card C1 pass through in the Z2 direction in the figure while facing the engaging portions 62 and 62 facing the left and right in the X direction across the storage space 30. Then, the back surface 1b of the first card C1 contacts the apex of the elastic portion 61 formed in the convex arch shape (first state) of the positioning mechanism 60.

  When the lid 50 is rotated from the open posture shown in FIG. 2 to the closed posture shown in FIG. 3, the ceiling surface 51 of the lid 50 presses the surface 1a of the first card C1 downward. As a result, the first card C1 is pushed down in the Z1 direction, and the back surface 1b of the first card C1 pushes down the apex of the elastic portion 61, so that the elastic portion 61 is formed as shown in FIGS. 5B, 6B, and 7. It is deformed into a linear shape (second state).

  Then, the facing distance between the engaging portions 62 and 62 directed to the left and right ends of the elastic portion 61 is narrowed, and enters the left and right intermediate recesses 8 and 8 of the first card C1, respectively. Match. The dimensions of the engaging portions 62, 62 in the Y direction are the same as the dimensions of the intermediate recesses 8, 8 formed in the first card C1 in the Y direction, or slightly smaller than that. Therefore, the first card C1 can be positioned in the front-rear direction (Y direction).

  At this time, if the lower slopes 62b, 62b formed in the engaging portions 62, 62 press the intermediate recesses 8, 8 downward in the figure, the first card C1 can be positioned in the plate thickness direction. . Even when the pressing is not performed, the engaging portions 62 and 62 are disposed opposite to the positions above the intermediate recesses 8 and 8, and therefore, when the first card C1 moves upward in the plate thickness direction, the intermediate recess 8 , 8 come into contact with the lower slopes 62b, 62b of the engaging portions 62, 62. For this reason, the first card C1 cannot easily be removed from the storage space 30 in the housing body 21 upward in the thickness direction.

  That is, in the positioning mechanism 60, the first card C1 can be positioned at an appropriate position in the card connector 20, and the first card C1 comes out of the storage space 30 in the housing body 21. Can be prevented (prevention of retaining).

  Further, when the lid body 50 rotated to the closed posture is slid forward (Y1 direction), the fulcrum shafts 54a and 55a provided on the lid body 50 are supported long holes 38a and 39a formed in the housing body 21. Move forward (Y1 direction). As a result, as shown in FIG. 4, the hook portions 56 a and 56 a provided on the lid body 50 enter the lower side of the lock projections 37 and 37 provided on both sides of the housing body 21, and the lid body 50. Is locked so as not to open. At this time, as shown in FIG. 4, a second hooking portion formed on the left side plate 24 of the housing body 21 is provided with a hooking portion 57 a at the tip of the lock plate spring 57 provided on the left side portion of the lid 50. It fits into the recess 25c and is lightly locked so that the lid 50 does not easily move backward (Y2 direction), that is, the hook portions 56a, 56a are not easily detached from the lock projections 37, 37.

  Thus, when the lid 50 is set from the closed posture to the locked posture, the lid 50 does not return to the open posture away from the opening provided above the housing body 21, and the elastic portion 61 of the positioning mechanism 60. Can be prevented from being restored to the original first state (see FIG. 5A) in the upper direction (Z1 direction). That is, since the engagement portion 62 is engaged with the left and right intermediate recesses 8 and 8, the first card C1 can be stably held in the storage space 30.

  The elastic portion 61 of the positioning mechanism 60 continues to urge the back surface 1b of the first card C1 upward. When the lid 50 in the locked position is lightly pressed downward in the figure and is slid backward (Y2 direction), the hook portions 56a and 56a are disengaged from the lock convex portions 37 and 37. Then, since the first card C1 is rotated together with the lid 50 by the urging force of the elastic portion 61 of the positioning mechanism 60, the card connector 20 can be set to the open posture as shown in FIGS. . At this time, since the first card C1 is also pushed upward in the figure (Z1 direction), the first card C1 can be easily removed from the storage space 30.

  Note that the positioning mechanism 60 may be of a type in which the elastic portion 61 is inverted so as to form a convex (reverse convex arch shape) in the opposite direction (downward) to that shown in FIG. In this case, just by loading the first card C1, the back surface 1b presses the apex of the elastic part 61 downward, the elastic part 61 is inverted, and the holding part 62 engages the intermediate recesses 8 and 8. . That is, the first card C1 can be positioned in the storage space 30 without rotating the lid 50 in the closed posture.

  As shown in FIGS. 2 to 4, when the first card C1 is mounted in the storage space 30 of the housing body 21 in a normal orientation, the identification formed on both sides of the first card C1. The grooves 6 and 6 are disposed upward inside the right side plate 25 and the left side plate 24 of the housing body 21. However, in the first card C1, the length dimension L1 of the identification groove 6 is short, and the inclined portion 6b, which is the step portion of the identification portion, is in front of the movable detection member 41 constituting the detection mechanism 40 (Y1 side). ).

  Therefore, at the position shown in FIG. 3, when the lid 50 is rotated to the closed posture, the identification sliding portion 58b at the tip of the detection plate spring 58 provided on the lid 50 is the surface of the first card C1. At 1a, the detection leaf spring 58 is deformed upward. The state in which the detection leaf spring 58 is bent and deformed upward is the second posture.

  As shown in FIG. 10A, when the lid 50 in the closed posture is slid forward as it is and set to the locked posture, the identification sliding portion 58b slides forward on the surface 1a of the first card C1, and the detection plate The spring 58 moves forward while being deformed upward. Therefore, the pressing action portion 58 c at the tip of the detection leaf spring 58 does not hit the movable detection member 41 both when the lid body 50 is rotated to the closed posture and slid to the lock posture.

  Therefore, in a state where the first card C1 is mounted, the movable detection member 41 is elastically coupled to the elastic movable contact 42b until the lid 50 shifts from the closed position to the locked position as shown in FIG. 10A. The elastic contact point 42c is lifted by the movable contact point 42c, and the elastic contact point 42c is detached from the fixed contact point 44, so that the fixed contact point 43 and the fixed contact point 44 are non-conductive.

  On the circuit board of the electronic device, a control unit mainly including a CPU is mounted together with the card connector 20. This control unit recognizes that the first card C1 has been normally mounted as follows.

  When the first card C1 is mounted in the normal orientation in the storage space 30 of the housing body 21 and the lid 50 is in the locked posture shown in FIG. 4, the individual provided on the back surface 1b of the first card C1. Since the external connection portion 5 is repressed with a larger force, each of the connection terminals 31 provided at the bottom of the storage space 30 shown in FIG. At this point, the control unit recognizes that the card is mounted in the storage space 30 in a normal posture. For example, in this type of card, one of a plurality of external connection portions 5 is generally short-circuited with each other in an internal circuit. Therefore, the control unit can determine that the card is normally mounted by detecting that the predetermined connection terminals 31 are short-circuited with each other.

  When it is determined that the card is normally installed, it is checked whether the fixed contact 43 and the fixed contact 44 provided in the detection mechanism 40 are short-circuited. It is determined that the card is the first card C1.

  As shown in FIGS. 4 and 10A, when the first card C1 is loaded and the lid 50 is moved to the locked position, the first sliding member 58b of the detection plate spring 58 provided on the lid 50 causes the first slide. The surface 1 a of the card C <b> 1 is pressed toward the bottom of the storage space 30. Therefore, this also secures the connection between the external connection portion 5 provided on the back surface 1b of the first card C1 and the connection terminal 31 provided on the housing body 21, and is conductive even if external vibrations or the like are applied. The state can always be maintained.

  When no card is loaded in the storage space 30 of the card connector 20, even if the lid 50 slides into the locked position, no external force acts on the detection plate spring 58, and the elastic arm portion 58 a is attached to the ceiling plate 51. Are located on the same plane. Thus, the detection leaf spring 58 is in the first posture when not deformed upward. At this time, the pressing action portion 58 c at the tip of the detection plate spring 58 rides on the pressing surface 45 b of the movable detection member 41. Since the elastic action contacts 42b and 42c shown in FIG. 9 have a larger force for the pressing action portion 58c of the detection leaf spring 58 to push down the pressing surface 45b than the force for pushing up the movable detection member 41, the lid When the body 50 slides into the locked posture, the movable detection member 41 is pushed down. As shown in FIG. 10A, when the movable detection member 41 is pushed down, the elastic movable contact 42b comes into contact with the fixed contact 43, the elastic movable contact 42c comes into contact with the fixed contact 44, and the torsion spring 42 contacts the fixed contact 43. The fixed contact 44 is conducted.

  In the detection mechanism 40, when the card is not mounted, the fixed contact 43 and the fixed contact 44 are always in a conductive state, the first card C1 is mounted in a normal posture, and the lid 50 is in a locked posture. As shown in FIG. 10A, the fixed contact 43 and the fixed contact 44 become non-conductive. In this way, if the fixed contact is made conductive when no card is loaded, the probability of erroneous recognition that the first card C1 is loaded can be reduced. For example, in the reverse case, the fixed contact 43 and the fixed contact 44 are in a non-conductive state when no card is mounted, and the fixed contact 43 is fixed when the first card C1 is normally mounted. When the contact 44 is in a conductive state, the first card C1 is mounted when a metal piece or the like is interposed between the fixed contact 43 and the fixed contact 44 when the card is not mounted. Although it is not, there is a risk of misrecognizing that it is in a worn state.

Next, the installation procedure of the second card C2 is the same as the installation procedure of the first card C1.
However, as shown in FIG. 19, the length dimension L11 of the identification groove 16 formed in the second card C2 is longer than the length dimension L1 of the identification groove 6 of the first card C1 shown in FIG. . Therefore, as shown by a dotted line in FIG. 3, when the second card C <b> 2 is mounted in a normal posture into the storage space 30 of the housing body 21, the identification unit is located at the rear end of the identification groove 16. The functioning inclined portion 16b is located behind (in the Y2 direction) the detection mechanism 40. Therefore, as shown in FIG. 4, when the lid 50 is rotated to the closed position, the identification sliding portion 58 b of the detection plate spring 58 provided in the lid 50 enters the identification groove 16. The detection leaf spring 58 is not deformed.

  At this time, the detection leaf spring 58 is in the first posture, and the elastic arm portion 58 a is located on the same plane as the ceiling plate 51.

  When the lid 50 is rotated to the closed posture, the pressing action portion 58 c at the tip of the detection leaf spring 58 faces the flank 45 a of the movable detection member 41. However, since the flank 45a is one step lower than the pressing surface 45b, the movable detecting member 41 does not move even if the pressing portion 58c provided on the detection plate spring 58 in the first posture faces the flank 45a. It will not be pushed down, or even if it is pushed down, its descending distance is small. Therefore, the elastic movable contact 42c remains away from the fixed contact 44, and the fixed contact 43 and the fixed contact 44 are in a non-conductive state.

  When the lid 50 in the closed posture shown in FIG. 3 is slid forward and shifted to the locked posture as shown in FIG. 4, the identification sliding portion 58 b at the tip of the detection leaf spring 58 moves in the identification groove 16. To do. As shown in FIG. 10B, the pressing action portion 58c at the tip of the detection leaf spring 58 rides on the pressing surface 45b on the upper surface of the movable detection member 41, and the movable detection member 41 is pushed down by the pressing action portion 58c. At this time, the elastic movable contact 42 c comes into contact with the fixed contact 44, and the fixed contact 43 and the fixed contact 44 are conducted through the torsion spring 42.

  When the control unit detects that the external connection unit 5 of the card and the connection terminal 31 shown in FIG. 2 are connected, the control unit confirms the continuity between the fixed contact 43 and the fixed contact 44 and is connected. Then, it is determined that the second card C2 is attached.

  As described above, the control unit monitors the state of the connection terminal 31 and the conduction state of the fixed contact 43 and the fixed contact 44 to determine whether the first card C1 or the second card C2 is loaded. Judging. And in a control part, control operation suitable for each specification of the 1st card | curd C1 and the 2nd card | curd C2 is performed. For example, when the driving voltages are different between the first card C1 and the second card C2, different voltages are supplied to the cards. When the memory capacity of the first card C1 is different from that of the second card C2, information on the remaining memory capacity of each card is taken into the control unit, and the subsequent recording data amount is adjusted.

(Second Embodiment)
FIG. 16 is a perspective view showing an open state of the card connector according to the second embodiment.

  The basic configuration of the card connector shown in the second embodiment is substantially the same as that of the card connector 20 of the first embodiment. For this reason, the following description will focus on differences from the first embodiment.

  The card connector 20B shown in FIG. 12 as the second embodiment is different from the card connector 20A of the first embodiment in the configuration of the positioning mechanism.

  That is, in the card connector 20B, the missing portions 24f and 25f are formed in the left side plate 24 and the right side plate 25 constituting the housing body 21, and the positioning mechanisms 80 and 80 are respectively provided in the missing portions 24f and 25f. Is provided.

  The positioning mechanisms 80, 80 are configured to include elastic arms (elastic portions) 81, 81, and locking portions 82, 82 formed in a mountain fold toward the storage space 30 of the housing body 21 at the tips thereof. Has been.

  The elastic arms 81 and 81 and the locking portions 82 and 82 are integrally formed by a metal leaf spring. The elastic arms 81, 81 are embedded by insert molding in one of the opposing surfaces 24f1, 25f1 forming the defect portions 24f, 25f, and are supported in a cantilevered state. For this reason, the positioning mechanisms 80, 80 are elastically deformable in the width direction (X1 and X2 directions) using the Y2 side proximal ends of the elastic arms 81, 81 as fulcrums. is there.

  The structure of the latching | locking parts 82 and 82 is the same as that of the engaging part 62 shown in the said 1st Embodiment, and has the latching | locking part 82 which protrudes in the storage space 30 side. An upper slope 82a and a lower slope 82b are integrally formed at the upper portion and the lower portion of the locking portion 82, respectively (see FIG. 15).

  As shown in FIG. 13, in the initial state where the card (the first card C1 or the second card C2) is not loaded in the storage space 30, the elastic arms 81, 81 of the positioning mechanisms 80, 80 are in the Y direction. Is in a first state parallel to. In the first state, the opposing dimension LL3 between the left and right engaging parts 82 and the engaging part 82 facing each other in the width (X) direction is slightly smaller than the width dimension W0 of the first and second cards C1 and C2. Narrow dimensions are set.

  Then, as shown in FIGS. 12 and 14, when the first card C1 (the same applies to the second card C2) is attached to the card connector 20B in a normal posture, the left and right sides of the back surface 1b of the first card C1 Both the edge portions abut against the upper slopes 82a and 82a of the locking portions 82 and 82, respectively. At this time, the elastic arms 81 and 81 have the proximal end as a fulcrum, and the opposing distances of the locking portions 82 and 82 on the distal end side are pushed away from each other to increase the opposing dimension LL3 (second state).

  When the first card C1 is further inserted into the card connector 20B, the engaging portions 82 and 82 get over the space between the back surface 1b and the inner bottom ends 8d and 8d in the plate thickness direction. Then, as shown in FIG. 15, when the elastic arms 81, 81 that are in the second state by pushing the distal end side are restored to the original parallel first state (the state of the opposing dimension LL 3), the locking portion The lower inclined surfaces 82b, 82b of the 82, 82 engage the intermediate recesses 8, 8. Thereby, since the latching | locking parts 82 and 82 hold | maintain the intermediate | middle recessed parts 8 and 8, even if it is a case where the cover body 50 exists in an open attitude | position, the 1st card | curd C1 can be stably in the appropriate position in the card connector 20B. Can be positioned.

  It should be noted that the movement of the first card C1 in the plate thickness direction, the width (X) direction, and the front and rear (Y) direction is restricted when the locking portions 82 and 82 engage the intermediate recesses 8 and 8, respectively. May be. In this case, the first card C1 is not easily detached from the housing body 21, and it is possible to prevent the first card C1 from being detached.

  Then, as in the first embodiment, the lid 50 is turned to the closed state, and further, the lid 50 in the closed posture is slid forward (Y1 direction). The hook portions 56a and 56a enter the lower side of the lock projections 37 and 37 provided on both sides of the housing body 21, and are locked so that the lid 50 is not opened. Thereby, the movement to the back (Y2 direction) of the cover body 50 is restrict | limited.

  The subsequent operation is the same as that in the first embodiment, and for example, it is determined whether or not the first card C1 or the second card C2 is normally mounted.
