DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an attachment / detachment mechanism for an additional function unit in a portable radio communication device according to the present invention will be described with reference to FIGS. In the present invention, a mounting hole 2 is provided on a side portion of the portable wireless communication device 1, and a mounting unit 2 for an additional function is removably mounted through the mounting hole 2. The unit holding portion 7 is provided on the resin cap 3 formed so as to be fittable.
Thus, the unit 10 is mounted by holding the unit 10 and fitting the cap 3 into the mounting hole 2. In the embodiment, long and short legs 4 and 5 for holding are provided as the unit holding portion 7, and the unit 10 is held and held by the legs 4 and 5.

As shown in FIGS. 2 and 3, a connector 23 is mounted on a printed circuit board 22 inside the device. When the unit 10 is mounted through the mounting hole 2, a connector portion at the tip of the unit 10 is mounted. 11 are joined and electrically connected. A guide portion 6a formed by processing a part of the shield plate 6 is provided inside the mounting hole 2, and one of the longer leg portions 4 is formed by the guide portion 6a.
Are guided to prevent the unit 10 from being erroneously inserted.

The leg 4 has a tapered outer surface, and the legs 4 and 5 are provided at different positions so that the unit 10 is eccentrically clamped. There is no misplacement, and erroneous insertion is more reliably prevented.

The unit 10 has a sheet 1 for removal.
4 and 5, the connector 13 of the unit 10 is inserted through the insertion hole 13a at the center of the sheet 13 and the sheet 13 is wound around the unit 10, and the end of the sheet 13 is attached as shown in FIGS. 14 is sealed. With the end 14 turned up, the unit 10 is connected to the legs 4 of the cap 3.
Insert between 5 and hold. In this case, the end 1
The four sides are located on one leg 4 side.

The cap 3 has an engaging claw 3a for engaging with the opening edge of the mounting hole 2 and a claw 4a for hooking a sheet at the tip of the longer leg portion 4.
The end 14 of the sheet 13 is in a state of being caught by the claw 4a.

FIGS. 6 and 7 show the cap 3 and the unit 1 respectively.
