Description

  The present invention relates to a card insertion / removal mechanism for removably fixing a card to / from the apparatus main body.

  Conventionally, a card such as an IC card or a memory card is used as a storage medium in an electronic device such as a mobile phone or a personal computer. The card is detachably fixed to the apparatus main body, and information is read and written at a fixed position of the card.

  The apparatus main body is provided with an ejector member that moves in the insertion / removal direction together with the card when the card is inserted / removed. A heart cam groove is formed in the ejector member, and a cam pin that moves inside the heart cam groove is disposed in the apparatus main body. The ejector member is biased in the removal direction by a biasing member such as a coil spring.

  In this card detaching mechanism, when the user inserts the card into the apparatus main body, the ejector member and the card are first involved. After the card is inserted to the deepest part of the device body against the biasing force of the biasing member, the ejector member is fixed by the operation of the heart cam groove and the cam pin when the card is slightly moved in the removal direction by the biasing force. Locked in position. From this state, when the user again moves the card from the fixed position in the insertion direction, the card is moved to the removal position where the card is discharged from the apparatus main body by a predetermined amount by the biasing force of the biasing member.

Here, the ejector member is urged in the removal direction by the urging member, and when the card is unlocked, if the ejector member and the card move vigorously from the fixed position to the removal position, the card is excessively moved. There is a problem of jumping out. In order to solve this problem, a card in which a notch is formed and a protrusion corresponding to the notch is provided on the ejector member has been proposed. The protrusion is formed in a mountain shape having an inclined surface, and is configured so as not to hinder the card removal.
JP 200526016 A

  However, in the card insertion / removal mechanism, since the protrusions get over the notched portion without hindering the card removal, the card cannot be sufficiently prevented from popping out. Here, if the protrusion is enlarged or formed in a rectangular shape to sufficiently prevent the card from popping out, the protrusion is likely to be caught in the notch, and conversely, the removal of the card will be hindered.

  In the card detaching mechanism, since no protective member is provided on the card, if the card falls due to the card popping out or the like, the card is directly impacted and there is a problem that the card is not protected. is doing.

  The present invention has been made in view of the above circumstances, and provides a card insertion / removal mechanism that reliably prevents the card from popping out of the main body of the apparatus and improves the protection performance of the card when the card is dropped. It is.

  In the present invention that solves the above-mentioned problems, a device main body for removably fixing a card is provided so as to be movable in the card insertion / removal direction, and is moved in the insertion / removal direction together with the card when the card is inserted / removed. And an ejector member that is fixed together with the card at a predetermined fixing position in the apparatus main body, and a card cover that covers at least a part of the card, and the card and the ejector member are engaged with each other, It is configured to be relatively movable in a non-insertion / removal direction different from the insertion / removal direction, and an engagement portion is provided on the card cover, and an engagement portion that is detachable from the engagement portion is provided on the ejector member, When the card is inserted into the apparatus main body and the ejector member moves to the fixed position, the ejector member moves relative to the card. The ejector member is moved to one side in the insertion / removal direction so that the engagement portion and the engaged portion are engaged, and the card and the ejector member are moved in the removal / removal direction from the fixed position. On the other hand, when it moves to the other side in the non-insertion / removal direction, the engagement between the engagement portion and the engaged portion is released.

  According to the present invention, a card cover that covers at least a part of the card is attached to the card cover, and an engaging portion that is detachable from an engaged portion of the ejector member is provided on the card cover. When the card is inserted into the apparatus main body, the ejector member moves toward the fixed position with the card and the ejector member engaged. And when an ejector member moves to a fixed position, a card | curd moves to a non-insertion / extraction direction one side with respect to an ejector member, and an engaging part and an engaged part engage.

  As a result, even if the card and the ejector member move vigorously from the fixed position in the removal direction, the engaging portion and the engaged portion are in an engaged state. It does not jump out of the device body. As a result, it is possible to reliably prevent the card from popping out from the apparatus main body.

  When the card and the ejector member are moved in the removal direction from the fixed position, when the card moves to the other side in the non-insertion / removal direction with respect to the ejector member, the engagement between the engagement portion and the engaged portion is released, and the card Will be able to be detached from the ejector member.

  Also, since at least a part of the card is covered by the card cover, it is difficult for external force to act directly on the card body, shocks due to falling, etc. are mitigated, and the card body is damaged. And it becomes difficult.

  Thus, according to the present invention, since the engaging portion is provided on the card cover and the engaged portion is provided on the ejector member, it is possible to reliably prevent the card from popping out of the apparatus main body by these engagements. Can do. Moreover, since at least a part of the card is covered with the card cover, it is possible to improve the protection performance of the card when the card is dropped.

The ejector member 104 is provided so as to be movable in the insertion / removal direction of the card 200. When the card 200 is inserted / removed, the ejector member 104 moves together with the card 200 in the insertion / removal direction, and moves at a predetermined fixed position in the apparatus main body 300. It is fixed together with the card 200. Further, as shown in FIG. 1, the card insertion / removal mechanism includes a card cover 106 that covers at least a part of the card 200.

  As shown in FIG. 2, the mold part 100 includes a substantially rectangular flat plate-like base part 108 and connector terminals 110 arranged on the back side of the base part 108 in the insertion direction of the card 200. For example, the connector terminal 110 may be formed integrally with the base portion 108 or may be press-fitted into a hole formed in the base portion 108. The connector terminal 110 is electrically connected to the apparatus main body 300 side. As shown in FIG. 3, when the ejector member 104 and the card 200 reach the above-described fixed position, information is transmitted between the storage unit of the card 200 and the apparatus main body 300 side. Can be sent and received. The connector terminal 110 also has a detection function of the card 200, and outputs a predetermined signal to the apparatus main body 300 when the card 200 reaches a fixed position.

  As shown in FIG. 2, wall portions 112 extending upward are formed at the front end and the left and right ends of the base portion 108. Then, a substantially rectangular flat metal plate 102 is connected to the upper end of the wall portion 112, and a rear portion is opened by the mold portion 100 and the metal plate 102 to form a bag-like portion into which the card 200 can be inserted.

  A part of the left wall part 112 of the base part 108 is missing, and the cam pin 114 is arranged in this missing part. The cam pin 114 moves inside a heart cam groove 116 (see FIG. 4) formed on the left side of the ejector member 104. By the heart cam groove 116 and the cam pin 114, the ejector member 104 and the card 200 are locked at the fixed position, and the card 200 is allowed to be detached from the ejector member 104 while being moved from the fixed position in the removal direction.

  As shown in FIG. 4, the front end of the ejector member 104 is formed with a locking portion 118 that contacts the left side of the front end of the card 200 when the card 200 is inserted and removed. On the rear end side of the ejector member 104, a holding claw 120 that holds a notch 202 formed on the left side of the card 200 when the card 200 is inserted and removed is formed.

  In addition, as shown in FIG. 2, the ejector member 104 is constantly urged toward the removal direction side of the card 200 by a coil spring 122 as an urging member. As shown in FIG. 5, a hole-shaped spring receiving portion 124 extending in the front-rear direction is formed on the lower side of the ejector member 104, and the coil spring 122 can be expanded and contracted in the spring receiving portion 124. The front end of the coil spring 122 is locked to the front wall portion 112 of the mold portion 100, and the rear end of the coil spring 122 is locked to a spring receiving portion 126 formed at the rear end portion of the spring receiving portion 124 of the ejector member 104. To do.

  As shown in FIG. 4, a protrusion 130 formed on the card cover 106 and a hole 130 that can be engaged and disengaged are formed on the upper portion of the ejector member 104. The hole 130 is formed in a substantially circular shape when viewed from above, and the horizontal movement of the card 200 with respect to the ejector member 104 is prevented in a state where the protrusion 128 is received.

Here, the card cover 106 will be described.
As shown in FIG. 1, the card cover 106 is formed in a substantially L-shaped flat plate shape along the rear end and the left end of the card 200 when viewed from above. Further, as shown in FIG. 6, a flange portion 132 that extends downward along the side portion of the rear end of the card 200 is formed in the rear portion of the card cover 106. That is, the card cover 106 covers the rear end side and the left end side of the card 200 from the upper side, and covers the side portion of the rear end of the card 200.

  An extension part 134 that extends slightly to the left is formed at the front end of the card cover 106. The above-described protrusion 128 is formed on the lower surface of the extending portion 134. The protrusion 128 is formed in a substantially circular shape when viewed from above. Here, since the left end front side of the card 200 is cut out, the extending portion 134 of the card cover 106 protrudes from the card 200 in a top view.

  Further, as shown in FIG. 4, an inclined surface 136 that is inclined forward and upward is formed at the lower front end of the ejector member 104. The inclined surface 136 is in sliding contact with a sliding contact portion 138 formed on the left end front side of the base portion 108 of the mold portion 100 when the ejector member 104 moves in the insertion direction. As shown in FIG. 7, the sliding contact portion 138 is formed so as to protrude upward from the base portion 108, and the back side (front side) in the insertion direction is substantially flat and the front side (rear side) in the insertion direction is inclined upward. Has been. Thus, when the ejector member 104 moves in the insertion direction, the ejector member 104 slides in contact with the sliding contact portion 138 and moves upward.

  Here, the ejector member 104 can move up and down in the mold part 100 and the metal plate 102. As shown in FIG. 7, a hole 140 into which the ejector member 104 is fitted is formed in the base portion 108 of the mold portion 100, so that the vertical stroke of the ejector member 104 is sufficiently secured and a card detaching mechanism is provided. The thickness is reduced.

  The card 200 and the ejector member 104 are relatively movable in a non-insertion / removal direction (vertical direction) different from the insertion / removal direction (front / rear direction) while being engaged with each other as shown in FIG. When the ejector member 104 moves upward with respect to the card 200 in a state where the front end of the card 200 is engaged with the engaging portion 118 of the ejector member 104, the protrusion 128 as the engaging portion and the hole portion 130 as the engaged portion. Engage with each other (see FIG. 9). On the contrary, when the ejector member 104 moves downward with respect to the card 200 with the front end of the card 200 engaged with the engaging portion 118 of the ejector member 104, the engagement between the protrusion 128 and the hole 130 is released. (See FIG. 8).

  The operation at the time of card insertion and removal in the card removal mechanism configured as described above will be described.

  When the card 200 is inserted into the apparatus main body 300, the ejector member 104 and the card 200 are first engaged as shown in FIG. Then, in a state where the card 200 and the ejector member 104 are engaged, the ejector member 104 moves to the deepest part in the insertion direction against the urging force of the coil spring 122. At this time, as shown in FIG. 9, the ejector member 104 moves upward by sliding contact with the sliding contact portion 138, so that the protrusion 128 of the card cover 106 and the hole portion 130 of the ejector member 104 are engaged.

  After the ejector member 104 moves to the deepest portion, when the card 200 is slightly moved in the removal direction by the biasing force of the coil spring 122, the ejector member 104 is locked at a fixed position by the operation of the heart cam groove 116 and the cam pin 114. At the fixed position, the ejector member 104 is in sliding contact with the sliding contact portion 138, and the height of the ejector member 104 with respect to the base portion 108 is maintained, so that the engagement between the protrusion 128 and the hole portion 130 is maintained. The

  Then, when the card 200 and the ejector member 104 move in the removal direction from the fixed position, the ejector member 104 comes out of the sliding contact section with the sliding contact portion 138, and the ejector member 104 falls into the hole 140 of the base portion 108 by its own weight. As a result, as shown in FIG. 8, the ejector member 104 moves downward with respect to the card 200, and the protrusion 128 comes out of the hole 130. In this manner, the engagement between the protrusion 128 and the hole 130 is released, and the card 200 is ready to be detached from the ejector member 104.

  Here, even if the card 200 and the ejector member 104 move vigorously in the removal direction from the fixed position, the ejector member 104 does not move downward, and the protrusion 128 and the hole 130 are not as shown in FIG. Since it is in the engaged state, the card 200 does not detach from the ejector member 104 and jump out of the apparatus main body 300 due to inertia. As a result, the card 200 can be reliably prevented from popping out from the apparatus main body 300.

  Further, according to the card insertion / removal mechanism of the present embodiment, since the card 200 is at least partially covered by the card cover 106, it is difficult for an external force to act directly on the main body of the card 200, and an impact caused by dropping or the like. Is alleviated and the main body of the card 200 is hardly damaged.

  In particular, in the present embodiment, since the rear portion of the card 200 which is the leading side in the removal direction is covered, the protection performance of the card when the card is dropped can be effectively improved. Further, the user can handle the card 200 by holding the card cover 106, which is extremely convenient in practical use.

  Further, according to the card insertion / removal mechanism of the present embodiment, since the ejector member 104 is moved downward by its own weight, it is not necessary to separately provide a mechanism or the like for the disengagement operation, thereby reducing the number of parts. In addition, the disengagement operation between the protrusion 128 and the hole 130 can be performed reliably.

  Further, according to the card attaching / detaching mechanism of the present embodiment, the ejector member 104 is moved upward by the sliding contact portion 138 formed on the apparatus main body 300 side. For example, the ejector member 104 is interposed via a link mechanism or the like. The relative movement between the ejector member 104 and the card 200 can be reliably performed as compared with the case where the card member 200 is raised or the card 200 is lowered.

  Further, according to the card attaching / detaching mechanism of the present embodiment, since the engaging portion and the engaged portion are configured by the protrusion 128 and the hole portion 130, the processing of the card cover 106 and the ejector member 104 is easy and easy.

  In the embodiment, the mold unit 100 and the metal plate 102 are fixed to the apparatus main body 300, and the ejector member 104 is provided in the apparatus main body 300 via the mold unit 100. The ejector member 104 may be provided directly.

  In the above embodiment, the card cover 106 is formed with the protrusion 128 and the ejector member 104 is formed with the hole 130. However, the ejector member 104 is formed with the protrusion 128 and the card cover 106 is formed with the hole. 130 may be formed. Further, the engaging portion and the engaged portion are not limited to the combination of the projection and the hole portion, and may be a combination such as a claw and a notch, for example. The shape, structure, etc. of the part are arbitrary.

  In addition, although the card 200 and the ejector member 104 are shown with the non-insertion / removal direction in which the card 200 and the ejector member 104 are movable relative to each other as the vertical direction, the card 200 and the ejector member 104 may be, for example, a horizontal direction or a rotation direction around a predetermined axis. In short, when moving to the fixed position, the ejector member 104 moves to one side in the non-insertion / removal direction with respect to the card 200, and the engaging portion and the engaged portion engage to move from the fixed position to the removal direction. In this state, the ejector member 104 may move to the other side in the non-insertion / removal direction with respect to the card 200 so that the engagement between the engaging portion and the engaged portion is released.

  Further, for example, as shown in FIG. 11, a notch 150 may be formed in the metal plate 102 corresponding to the card cover 106. That is, by forming the notch 150 in the movement locus of the card cover 106 so that the card cover 106 and the metal plate 102 do not interfere with each other, the bag portion of the mold part 100 and the metal plate 102 can be formed thin. Thereby, even if the card cover 106 is provided on the card 200 and the thickness of the entire card 200 side is increased, the bag-shaped portion made of the mold portion 100 and the metal plate 102 is not thickened.

  In the embodiment, the card cover 106 covers the left side and the rear side of the card 200. However, the card cover 106 may cover other parts. Further, the card cover 106 does not cover a part of the card 200, and the card cover 106 may cover almost the entire card 200.

  Furthermore, although a card detaching mechanism using a push-on / push-off type heart cam mechanism has been shown, for example, the present invention can also be applied to a lever eject type detaching mechanism. Of course, it is possible to appropriately change the specific detailed structure and the like.
