  FIG. 4 shows a state where the inserted tray 33 is locked at the insertion position by the connecting rod 44 of the insertion / removal mechanism 41. FIG. 5 shows a state in which the pressed tray 31 is pulled out by the action of the connecting rod 44 of the insertion / removal mechanism 41. Since the operation of the insertion / extraction mechanism 41 is a conventional technique, a detailed description of the operation is omitted.

The above is the description of the configuration of the present embodiment. Subsequently, the operation state of the present embodiment will be described.
The relationship between the tray 31 and the insertion / extraction mechanism 41 is the emphasis of this embodiment. Since the relationship between the tray 31 and the memory card is not important in the present embodiment, the memory card is not displayed in the drawing, and only the card mounting portion 32 and the card mounting portion 33 of the tray 31 are displayed.

  As shown in FIGS. 11 and 12, before the tray 31 is inserted, the connecting rod 44 is pushed to one side by the side elastic unit 51 and abuts against the fixed wall surface 124. The connecting rod 44 is limited by the support portion 123 and the pressing portion 161. At this time, the connecting rod 44 is fixed at the predetermined position.

  As shown in FIGS. 13 and 14, when the tray 31 is inserted, the open end 351 of the expansion groove 35 corresponds to a predetermined position and can receive the connecting portion 442 of the connecting rod 44. The extension groove 35 gradually decreases in height from the front to the rear, and the lowest position is lower than the connecting portion 442. Therefore, the connecting portion 442 can smoothly enter the expansion groove 35. When the tray 31 is fully inserted, the connecting portion 442 acts by contacting the heart-shaped lead groove 42.

  When the insertion force (for example, the force of the user's finger) is released, the tray 31 moves to the outside by the action of the spring 46 as shown in FIG. The connecting rod 44 acts on the heart-shaped lead groove 42 and locks the tray 31 in a position where it enters. At this time, the heart-shaped lead groove 42, the connecting rod 44, and the elastic unit 46 of the insertion / extraction mechanism 41 act on the tray 31. Therefore, if the user pushes the tray 31, the insertion / removal operation can be performed. When the insertion / removal operation is advanced, the connecting rod 44 is not fixed and restricted due to the elastic action of the side elastic unit 51, so that the elastic action of the side elastic unit 51 after acting the heart-shaped lead groove 42. The swing operation can be maintained normally. On the other hand, if the tray 31 on which the two memory cards are mounted is inserted into the card mounting portion 32 and the card mounting portion 33 as far as possible, the two memory cards can be connected to the two terminal groups for use. it can.

  When the memory card is taken out, if the tray 31 is pushed, the tray 31 can be moved backward to a certain distance by operating the insertion / removal mechanism 41 as shown in FIG. The fixed distance by which the tray 31 is retracted to the outside, that is, the distance between the connecting portion 442 of the connecting rod 44 and the two stop points on the heart-shaped lead groove 42 is a conventional technique related to the heart-shaped lead groove 42. Therefore, detailed description is omitted. At this time, the tray 31 can be extracted from the housing 11. When the tray 31 is extracted, the connecting rod 442 of the connecting rod 44 is detached from the expansion groove 35 and separated from the tray 31. Therefore, the tray 31 is smoothly extracted from the housing 11. The connecting portion 442 of the connecting rod 44 returns to the predetermined position described above by the action of the side elastic unit 51. At this time, as shown in FIG. 11 or FIG. 12, the state before the tray 31 is inserted into the housing 11 is restored. On the other hand, since the fixing portion 461 of the elastic unit 46 is fixed to the corresponding portion 122 of the housing 11, even if the tray 31 is pulled out from the housing 11, the elastic unit 46 does not deviate from the housing and fall outside. Does not occur.

  As described above, the memory card connector according to the present embodiment has an insertion / removal function. Further, when the tray 31 is attached to and detached from the memory card connector, the normal operation of the tray 31 can be maintained and the convenience in use can be improved.

  In the present embodiment, the fixing portion 461 of the elastic unit 46 is not necessarily a necessary part. In the present invention, not only the fixing portion 461 is disposed, but the elastic unit 46 is limited by the internal space of the housing 11, or the elastic unit 46 and the fixing pin 121 are disposed in close contact with each other. 46 can be prevented from deviating.

  On the other hand, the fixing pin 121 is not necessarily a necessary part. The elastic unit 46 can be fixed by the restriction of the internal space of the housing 11. Therefore, the present invention does not necessarily require the fixing pin 121 to be disposed.

  The arrangement position of the heart-shaped lead groove 42 and the expansion groove 35 is not necessarily the top surface of the side portion 34. In contrast to the above-described prior art disclosing means for disposing the heart-shaped lead groove 42 on the side surface of the tray, the heart-shaped lead groove 42 and the expansion groove 35 in the present invention may be disposed on either surface. It only needs to be able to perform the insertion / removal operation.

  On the other hand, the support part 123 is not necessarily a necessary part. Even if the support portion 123 is not disposed, the connecting rod 44 can normally perform the swing operation by the elasticity of the side elastic unit 51 and the connection with the heart-shaped lead groove 42.

  On the other hand, one example is that the card mounting section 32 and the card mounting section 33 of the terminal group 21 and the tray 31 are set to two. The present invention can be applied to a combination of one terminal group 21 and one card mounting portion 32 or card mounting portion 33. At this time, the tray 31 is loaded with only one memory card. The terminal group 21 is disposed on the base 12 or the lid 16. Since it can be selected after understanding according to the contents of the present invention, a state where one terminal group 21 and the card mounting portion 32 or the card mounting portion 33 are combined is not shown. That is, the present invention is not limited to the number of terminal groups 21, card mounting portions 32, and card mounting portions 33.
