FIG. 15 is a diagram showing an initial state when the third card is inserted into the present embodiment, where (a) is a plan view, (b) is a right sectional view, (c) is a left sectional view, d) The figure is a front view. 16A and 16B are views showing a state in which the third card inserted in the present embodiment is mounted at a predetermined third mounting position, where FIG. 16A is a plan view, FIG. 16B is a right side sectional view, and FIG. The figure is a left sectional view, and FIG.

  When the third card 3 which is the shortest of the three types of cards and is wider and thinner than the second card 2 is inserted from the insertion port 4a of the housing 4 shown in FIGS. 15 (a) and 15 (d), The third card 3 is inserted into the card insertion portion 4h while being guided by the third guide wall 4d and the fourth guide wall 4e of the insertion port 4a.

  Further, when the third card 3 is pushed in, the front end portion 3c of the third card 3 is engaged with the third contact portion 10c of the slide member 10 as shown in FIG. The slide member 10 moves toward the back of the apparatus against the urging force of the urging member 11 via the abutting portion 10c.

  The heart cam groove 12 formed in the slide member 10 moves toward the back of the apparatus integrally with the sliding of the slide member 10. As a result, the slide pin 13b of the lock member 13 relatively moves on the forward path 12a of the heart cam groove 12 shown in FIG.

  As shown in FIGS. 16A and 16C, the third card 3 is pushed to a predetermined third mounting position where the third external contact portion 3d contacts the protrusion 5a of the third contact terminal 5. When this occurs, the slide pin 13b of the lock member 13 is locked to the lock portion 12c of the heart cam groove 12 shown in FIG. Thereby, the slide member 10 is locked in a state where the third card 3 is held at the predetermined third mounting position. In this state, transmission / reception of signals to / from the third card 3 becomes possible.

  Note that, when the third card 3 is inserted, the third card 3 does not activate the detection switch 14.

  Further, when the third card 3 is ejected from the state in which the third card 3 is held at the predetermined third mounting position as described above, an operation of slightly pushing the third card 3 into the apparatus back side again is performed. Done. As a result, the slide member 10 overstrokes, and the slide pin 13b of the lock member 13 is detached from the lock portion 12c of the heart cam groove 12 accordingly. Therefore, the slide member 10 slides in the direction of the insertion port 4a by the biasing force of the biasing member 11, and the third card 3 is pushed out by the slide member 10 to the state shown in FIGS. 16 (a) and 16 (b). Return.

During this time, the slide pin 13b of the lock member 13 slides relatively on the return path 12b of the heart cam groove 12 shown in FIG. In the state shown in FIG. 16, the third card 3 can be easily removed from the housing 4 by gripping the end of the third card 3.

[Effect of this embodiment]
As described above, in the present embodiment, the first, second, and third contact terminals 5, 6 that contact the external contact portions 1d, 2d, 3d of the first, second, and third cards 1, 2, 3, respectively. , 7 are arranged in three rows on the bottom surface 4g of the card insertion portion 4h of the housing 4, and no contact terminals are provided on the top surface facing the bottom surface 4g. Thereby, the height dimension of the apparatus can be reduced, and the apparatus can be miniaturized. Since the first, second, and third contact terminals 5, 6, and 7 are arranged in three rows on the same bottom surface 4g of the card insertion portion 4h, the first, second, and third contact terminals 5 are provided. , 6 and 7 can be easily routed. This can reduce production costs.

  In the present embodiment, the protruding end portions 5b, 6b, and 7b that protrude from the housing 4 of the first, second, and third contact terminals 5, 6, and 7 are located outside the bottom surface 4g of the housing 4. Therefore, soldering to a predetermined substrate (not shown) can be easily performed. That is, it can be easily mounted on a predetermined substrate. This also makes it possible to reduce production costs.

  Further, in the present embodiment, since the widths of the protrusions 7a and 6a of the third and second contact terminals 7 and 6 are relatively small, the first card 1 and the third card 3 when the first card 1 is inserted. The friction between the second contact terminals 7 and 6 can be reduced, and the friction between the second card 2 and the third contact terminal 7 can be reduced when the second card 2 is inserted. Can do. Thereby, the wear of the first and second cards 1 and 2 can be suppressed, and a highly reliable device can be obtained.

  In the present embodiment, when the first card 1 is inserted, the third and second contact terminals 7 and 6 are pushed down by the second and first push-down members 9 and 8, so that the first card 1 and the third and third contact terminals 7 and 6 are pushed down. Rubbing due to friction with the second contact terminals 7 and 6 can be further reduced. Further, when the second card 2 is inserted, the third contact terminal 7 is pushed down by the second push-down member 9 so that the friction caused by the friction between the second card 2 and the third contact terminal 7 can be further reduced. . By these, it contributes to suppression of wear of the 1st, 2nd cards 1 and 2, and a more reliable device can be obtained.

  Further, in the present embodiment, the first, second, and third cards 1, 2, and 3 are respectively formed by the first, second, and third contact portions 10a, 10b, and 10c of the slide member 10 and the biasing member 11. Each can be discharged. That is, the first, second, and third cards 1, 2, and 3 can be discharged through one slide member 10, and the card discharge mechanism can be simplified. Accordingly, the first, second, and third cards 1, 2, and 3 can be easily removed from the apparatus, the number of parts can be reduced, the manufacturing cost can be reduced, and the apparatus can be downsized.

  In the present embodiment, each of the first, second, and third contact portions 10a, 10b, and 10c is inserted in the slide member 10 in the insertion direction of the first, second, and third cards 1, 2, and 3. Since it only needs to be formed by shifting, a simple configuration can be achieved, which contributes to lower production costs.

  In the present embodiment, the lock mechanism for holding the slide member 10 in a predetermined mounting position is constituted by the heart cam groove 12 and the lock member 13 that are simple in structure as is well known, and this also reduces the production cost. Contribute to doing.

  The present embodiment also includes a write protection detection switch 14 for detecting a write prohibition process for the second card 2, and the detection switch 14 is arranged so as not to operate when the first and third cards 1 and 3 are inserted. It is. Thereby, the write prohibition function with respect to the 2nd card | curd 2 can be ensured, and the function of an apparatus can be improved.
