DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the drawings. Note that the present invention is not limited by this. FIG. 1 is an exploded perspective view of a main part of a portable device equipped with a memory card according to an embodiment of the present invention, and FIG. 2 is a partial sectional view of the portable device equipped with a memory card of FIG.

The portable device equipped with the memory card has a substrate 1
Is sandwiched between the upper cover 8 and the lower cover 9. A battery holder 7 for holding the secondary battery 6 is attached inside the lower cover 9. A card connector 3 for inserting a memory card 5 is fixed to the upper surface of the substrate 1. Further, through holes 1a and 1b and rectangular through holes 1c and 1d are formed in the upper surface. The card guide 4 is for guiding the memory card 5 to the card connector 3.

It is fixed to the lower surface by attaching. Next, the card guide 4 is arranged in front of the card connector 3. The card guide 4 is sandwiched between the upper cover 8 and the substrate 1.

Next, the battery holder 7 is mounted inside the lower cover 9, and the secondary battery 6 is fitted into the battery holder 7.
Then, the lower cover 9 is attached to the lower surface of the substrate 1. In this state, the connection arm 25e is connected to the negative electrode 6 of the secondary battery 6.
Electrical connection is made with a. Also, the grounding arms 2f, 2g
Project from the through holes 1c and 1d of the substrate 1 toward the upper surface side of the substrate 1. Note that the secondary battery 6 is connected to the connection arm 25e.
, The connection failure does not occur.

When attaching the memory card 5, the memory card 5 is inserted into a space formed by the card guide 4 and the board 1. The memory card 5 slides on the board 1 and is guided to the card connector 3. At this time, the memory card 5
Grounding arm 2 protruding from through holes 1c and 1d of substrate 1
Press down f and 2g. As shown in FIG. 2, when the memory card 5 is fitted in the card connector 3, the grounding arms 2f and 2g make an electrical connection with the decorative plate 5a of the memory card 5 to ground static electricity. Since the memory card 5 pushes down the grounding arms 2f and 2g, a connection failure does not occur.

According to the above-mentioned portable device equipped with a memory card,
Since the connection terminal 2 is mounted on the lower surface of the substrate 1, a conventional guard plate is not required, and the thickness of the portable device with the memory card can be reduced.

Further, since the conventional ground terminal 23 and connection terminal 25 are integrated, the number of components and soldering work can be reduced, and assemblability can be improved and manufacturing cost can be reduced.

In the above embodiment, the connection arm for making an electrical connection with the negative electrode of the secondary battery is described as being provided at the connection terminal. However, when the secondary battery is not mounted, the connection arm is provided at the connection terminal. No need to provide.

[0018]

As described above, in the portable device with the memory card of the present invention, the connection terminal is attached to the surface (lower surface) opposite to the surface (upper surface) on which the card connector is arranged. For this reason, the conventional guard plate becomes unnecessary, and the thickness can be reduced. Further, it is not necessary to use a special card connector or to adjust the height of the card connector. Further, since the number of components and the soldering operation can be reduced, the assemblability can be improved and the manufacturing cost can be reduced.
