The recesses 73a, 73a and the flange 7
Coil springs 731 and 731 are provided between the coil springs 2b and 72b. For this reason, the coil springs 731 and 731
Separates the flanges 72b, 72b from the recesses 73a, 73a by a predetermined elastic force.
The movable portion 73 is fixed to the fixed portion 71 by the elastic force of
It is urged in the direction approaching.

For this reason, by applying a predetermined force against the elastic force of the coil springs 731 and 731,
Is movable in a direction away from the fixed portion 71, and
When the predetermined force is released, the movable part 73 is
Move in the direction approaching 1.

On the other hand, the fixing portion 71 is
2 has a connector connection portion 712 into which a cable terminal 83 provided at the tip is inserted. When the terminals of the connector connection section 712 and the cable terminals 83 are electrically connected, the pins 711,... And the cable terminals 83 are connected via the internal circuit of the external device connection adapter 700.

When the list-type music playback device 100 is set in the external device connection adapter 700 configured as described above, the main body 200 of the list-type music playback device 100 is fixed as shown in FIGS. It is held in a state sandwiched between the part 71 and the movable part 73. In this state, the pins 711,... Of the fixing portion 71 are inserted into the pin insertion holes 263,.

As described above, the movable part 73 is
Since the main body 200 is placed on the slide plate 72 by applying a force to the movable part 73 and moving it away from the fixed part 71, the movable part 73 is
When the force applied to the coil spring 73 is released,
The main body 200 is held by the urging force of the members 1 and 731 toward the fixed portion 71. The main body 200 set on the external device connection adapter 700 includes the coil spring 7
By being pressed against the fixing portion 71 by the elastic force of the base members 31 and 731 and the pins 711,... Being inserted into the pin insertion holes 263,.

Here, the pins 711,... Of the external device connection adapter 700 and the pin insertion holes 263,.
, That is, the structure of the waterproof terminal portion will be described with reference to FIG. This waterproof terminal portion is configured by disposing a connection pin 1254, a spring 1255, and a waterproof ring 1256 in a pin insertion hole 1263 formed in the main body 200. A plurality of pin insertion holes 1263 are formed in the main body 200. Here, one pin insertion hole 1263 will be described as an example, and the other pin insertion holes 1263 are similarly configured. And

The pin insertion hole 1263 is a through hole communicating between the inside and the outside of the main body 200, and is constituted by two portions having different diameters. That is, the diameter close to the outside of the main body 200 is large, and the diameter close to the inside of the main body 200 is small. The connection pin 1254 is inserted from the outside of the main body 200 into the narrow portion of the pin insertion hole 1263. The connection pin 1254 has a flange 1 at the rear end.
254a, and the flange 1254a is located at a wide portion of the pin insertion hole 1263, and has a connection pin 1254a.
Penetrates through the narrow portion of the pin insertion hole 1263 and reaches the inside of the main body 200.

Further, a waterproof ring 1256 is attached to the connection pin 1254. And waterproof ring 1
A spring 1255 is provided between the connection pin 256 and the flange 1254a of the connection pin 1254. That is, the connection pin 1
254 is inserted into the pin insertion hole 1263 with the spring 1255 and the waterproof ring 1256 interposed, and reaches the inside of the main body 200, and is urged to the outside of the main body 200 by the spring 1255. The tip of the connection pin 1254 is connected to the board terminal 1253 inside the main body 200.
When the connection pin 1254 moves toward the inside of the main body 200 against the elastic force of the spring 1255,
The connection pin 1254 and the board terminal 1253 come into contact and conduct.

In the waterproof terminal portion configured as described above, when the external device connection adapter 700 is attached to the wrist-type music playback device 100, the pin 711 is inserted into the pin insertion hole 1263. That is, as shown in FIGS. 17A and 17B, the pin 711 is
When inserted in the connection pin 711, the connection pin 125
4 is pressed, and the connection pin 1254 is pressed.
Moves toward the inside of the main body 200. Then, when the connection pin 1254 comes into contact with the board terminal 1253 in the main body 200, the pin 711 and the board terminal 1253 conduct. Thereby, the circuit inside the main body 200,
Cable 81 connected to external device connection adapter 700
Are connected. Here, the connection pin 1254 is movable in the pin insertion hole 1263, and a gap may be generated between the connection pin 1254 and the inner surface of the pin insertion hole 1263, but the waterproof ring 1256 is provided. Therefore, invasion of water, dirt, and the like into the main body 200 can be prevented.

In this embodiment, the structure of the pin insertion hole 1263 is exemplified as the waterproof terminal portion. However, the pin insertion hole 1264 of the earphone connection connector portion 206 of the main body 200 is similar to the above-mentioned waterproof terminal portion. It is composed of

In each of the above embodiments,
Although a wristwatch is used, the present invention is not limited to this, and may be another wrist device, a portable terminal, or the like. Further, the external storage medium is not limited to the small memory card, but may be any other one, and it is needless to say that the specific detailed structure can be appropriately changed.
