0B, the upper and lower metal shells 41A and 41B are securely assembled. When the mounting groove 68 is inserted into the mounting leg insertion space 90A, 90B, the upper and lower protrusions 70 of the mounting groove 68 are pressed against the inside of the bending engagement pieces 71A, 71B, and the mounting leg is inserted. 31A is firmly positioned. By selecting the length of the assembling piece 66 of the assembling leg 31A, the height on the upper surface of the printed circuit board 3 of the memory card drive device including the upper and lower drive devices 11A and 11B according to the selection. Is determined. For example, the length of the assembling piece 66 can be increased, and a lower space 80 can be defined between the surface of the lower metal shell 41B of the lower drive device 11B and the printed circuit board 3. This lower space 80 can be used as a mounting space for IC components, and serves to increase the component mounting density of the printed circuit board 3 on which the memory card drive device is mounted. The method for assembling the other mounting leg 31B on the right side with respect to the one mounting leg 31A is the same as that described above.

Next, the rear assembly legs 32A and 32B will be described. FIG. 17 shows one of the assembling legs 32A located on the left side, which is an assembling piece 72 that is located horizontally above and an assembling piece 72 that is spaced apart therefrom and that also extends vertically. A horizontal and vertical assembly piece 7 consisting of an attachment piece 73

2 on the upper receiving plate 76 and the end of the lower mounting piece 73 on the lower receiving plate 77,
A, 41B and the upper and lower housings 60A, 60B are assembled. Then, a screw 78 passed through a hole 75 is passed through each of the mounting holes 46A, 64A, 64B, 46B and the printed circuit board 3, and is fixed with a nut 79. Things.
By selecting the length of the leg piece 74 in the above, the upper and lower integrated memory card drive device 1 is selected according to the selection.
Above the printed circuit board 3 can be determined. For example, a lower space 80 can be defined between the surface of the printed circuit board 3 and the surface of the metal shell 41B of the lower drive device 11B. The same applies to the use of the other mounting leg 32B. Therefore, the height of the front end of the memory card drive device 1 on the printed circuit board 3 determined by the selection of the front mounting legs 31A and 31B, and the memory card drive on the printed circuit board 3 determined by the selection of the rear mounting legs 32A and 32B. If the height of the rear end of the device 1 is equal, the memory card drive device 1
Is mounted horizontally on the printed circuit board 3.

The upper and lower metal shells 41A and 41B, which are constituent members of the upper and lower drive units of the memory card drive unit 1, have left plates 43A and 43B integral with the top plates 42A and 42B, respectively. This portion guides the eject levers 56A or 56B so as to be slidable.
If two concave portions 82 are formed in A or 56B as shown in FIG. 26 and the convex portions 81 are formed on the surfaces of the left plates 43A and 43B of the respective metal shells, the eject lever 56 is formed.
Each of A and 56B is useful for holding the position when the eject lever 56A or 56B is slid to a predetermined position by the engagement of the concave portion 82 and the convex portion 81. Specifically, the eject lever 56A or 56B
Is completely inserted to the back, the concave portion 82 on the near side is
, The position is held more, and when pulled out to the front, the concave portion 82 at the back engages with the convex portion 81, and the position is held more.

The operation of inserting and removing the memory card 84 with the above configuration will be described with reference to FIGS. 27, 28 and 29.
(FIGS. 27, 28 and 29 show the lower drive device 11
This is shown by the back surface 42B of the shell 41B of B, and the operation of the upper drive device 11A is the same. FIG. 27 shows that the cam plate 51B has the first cam peak 52B.
Has been displaced so as to be in contact with the cam contact surface 48B, and the memory card 84 has been completely inserted.
4 and the contact portion 62B of the terminal 61B of the electrical connector 59B are connected to each other.
When the knob 57B is pushed from this state and the eject lever 56B is pushed backward as shown in FIG. 28, the cam plate 51B causes the second cam ridge 53B to contact the cam contact surface 48B. Is displaced to touch the
Accordingly, the ejection end 54B is displaced so as to protrude the memory card 84, and the knob 57B is still moved as shown in FIG.
When the eject lever 56B is pushed by pushing B, the cam plate 51B is displaced by the cam movement of the second cam peak 53B on the cam contact surface 48B so as to further project the eject end 54B, and the memory card 84 is removed. It will be escaped. However, in the case of this embodiment as well, the upper and lower drive devices 11 are used similarly to a conventionally known memory card drive device.
Instead of attaching the memory card 84 to each of the A and 11B, the space 6 of both the upper and lower drive devices 11A and 11B is replaced.
One hard disk can be mounted using 5A and 65B. When the cam plate 51A or 51B swings in the manner described above, the cam plate 51A or 51B is turned over by the folded piece 47A or 47B and the stopper forming piece 49A or 49B.
The cam plate 51A or 51B and the eject levers 56A, 56
The operation of B is smooth and stable,
The folded piece and the stopper forming piece are the metal shell 41A,
The top plate of 41B is folded or cut and raised, and is not formed using a special additional member. Therefore, the number of parts is small and the number of manufacturing steps is small.
In addition, the vertical drive device itself can be formed thin and small.

[0014]

As described above in detail, according to the present invention, since each of the upper and lower drive devices has a shell having a memory card mounting space, an electric connector, and an eject mechanism, it can be used as an individual drive device. ,
Since it is simply assembled into the upper and lower two-tiered drive device for mounting the upper and lower two-tiered memory card, when focusing on the entire upper and lower two-tiered shell, the number of parts and the number of assembling steps are reduced. In addition, since each component of the vertical drive device is the same component except that it has a vertically symmetrical shape, it is easy to design and manufacture. In particular, since the means for assembling the upper and lower drive devices vertically and the means for mounting the memory card drive device assembled in two upper and lower stages on the printed circuit board are implemented using the same assembling legs, the number of parts is reduced. It has few advantages, especially since the mounting legs only need to be inserted into the mounting leg insertion space formed between the engagement piece of the upper and lower drive devices and the side plate when bridging and mounting the upper and lower drive devices. Not only is it easy to work, but the gap in the assembly leg insertion space is formed slightly wider than the thickness of the assembly piece of the assembly leg. Since the projection is formed, when the assembly groove is inserted into the assembly leg insertion space, the projection is pressed against the inside of the bending engagement piece forming the assembly leg insertion space, The mounting legs can be positioned firmly. And other various advantages.
