Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an external device, and more particularly, to an external device which can be connected to an electronic device provided with a signal terminal in addition to a battery pack connecting terminal in a battery housing chamber.

[0002]

2. Description of the Related Art Conventionally, for example, in electronic equipment such as a still video (SV) camera, a reproducing device as an external device is connected to a disk device terminal by a connector through an external cable. That is, FIG. 5 shows a connection state when the reproducing device 2 is used for the SV camera 1 and signals such as a video signal, an audio signal or a data signal to a computer are output to various output devices 3.
Is a disk device built in the SV camera 1, 5 is its connector, and 6 is an external cable.

Therefore, as the reproducing apparatus 2, for example, FIG.
As shown in FIG. 6A, a connector 5 with a cable 6 is provided, and this connector 5 is attached to the camera 1 side, or as shown in FIG.
It was provided directly to the camera 1 without the intermediary, and was connected by mounting the connector 5 on the camera 1. Reference numeral 7 is an output terminal from the reproducing device, and a cable line on the output device 3 side is connected through the terminal 7.

However, when the SV camera 1 and the reproducing apparatus 2 are connected in such a state, the connection portion is easily disconnected due to static pressure applied to the connector or the external cable or external impact, and therefore the disconnection is prevented. Measures are required, and furthermore, since the connector 5 is exposed to the outside of the camera 1 and the external cable 6 is connected to this, noise from the outside is easily superimposed on the cable 6, or conversely to the outside. There was a problem that noise was dissipated.

SUMMARY OF THE INVENTION An object of the present invention is to pay attention to the above-mentioned conventional problems, and in order to solve the problems, a reproducing apparatus or the like is directly provided in a battery storage chamber of an electronic device storing a battery pack. It is an object of the present invention to provide an external device which is capable of accommodating the external device and is electrically connected to each part so as to be compact and to obtain a good electrical connection state.

[0006]

In order to achieve the above object, the present invention provides an external device which can be connected to an electronic device in which a signal terminal is provided in addition to a connection terminal for a battery pack in a battery storage chamber. And having a signal terminal that is connected to the signal terminal by being coupled to the electronic device, and at least a part of the external device has a shape similar to the battery pack, and the external device is used instead of the battery pack. By making it possible to store a portion having a similar shape of the device in the battery storage chamber, it is possible to reduce a portion of the external device protruding from the electronic device in a state where the external device is coupled to the electronic device. .

[0007]

According to the present invention, it is possible to mount an external device in a battery storage chamber for a battery pack device, and the power supply connection terminal and other signal supply connection terminals are connected to the device side in the mounted state. Since the connection state is maintained without being exposed to the outside with the external device side, it is possible to control disconnection of the connection portion, introduction of noise, or diffusion to the outside.

In particular, the battery storage chamber on the electronic device side is effectively used in order to reduce the size of the entire assembly of the external device and the electronic device.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below in detail and specifically with reference to the drawings.

1 and 2 show an example of the present invention.
The state where the battery pack is attached to the SV camera as the electronic device and the state where the reproducing device as the external device is attached are shown. That is, in FIG. 1, 10 is an SV camera 1.
Of the battery storage chamber, that is, the battery pack installed in the battery box portion 11, where the battery pack 10 has a form as shown in FIG. 3A, and a connection terminal 10A for power supply is provided on a part of its side surface. And 10B are provided.

Therefore, when mounting such a battery pack 10 on the camera 1, the battery box portion of the camera 1
As shown in FIG. 4 (A), the power supply connection terminal 11A
And 11B, there is provided a reproduction connection terminal 11C for signals other than a power supply such as a signal supply.
Connection terminals 10A and 10B for A and 11B and battery pack 10
And are connected as shown in the figure, and are fixed by mounting means (not shown).

Further, in FIG. 2, reference numeral 20 is a reproducing device, and in this case, the reproducing device 20 is installed in the battery box portion 11 itself in which the battery pack 10 is installed in FIG. Therefore, in the form of the reproducing device 20, the fitting part 21 inserted into the battery box part 11 and attached is formed in a shape similar to the battery pack 10 as shown in FIG. Are provided with connection terminals 20A and 20B for power supply and connection terminal 20C for non-power supply.

Therefore, when such a reproducing apparatus 20 is attached to the camera, the camera 1 is installed as shown in FIG. 4 (B).
By inserting the fitting portion 21 of the playback device 20 into the battery box portion 11 of the battery box portion 11, the connection terminals 20A, 20B and 20C are kept connected to the connection terminals 11A, 11B and 11C on the battery box portion 11 side, respectively. It can be fixed by the same mounting means as in the case of the pack 10.

FIG. 3C shows another embodiment of the present invention.
Among the connection terminals 20A, 20B, and 20C provided in the fitting portion of the reproduction device 20, the reproduction signal connection terminal 20C 'other than the power supply is made to be a plug-in type instead of a contact type, so that signal transmission can be performed more reliably. It is something that can be obtained. In the case of this example, the connection terminal (not shown but corresponding to 11C in FIG. 4B) provided on the battery box portion 11 side of the camera 1 corresponds to the above-mentioned connection terminal 20C '.
Needless to say, it is necessary to use a socket type that can be connected to. Furthermore, in this example, only one terminal 20C 'is a plug-type terminal, but all three terminals described above may be plug-type terminals.

In the above description, the SV is used as an electronic device.
Although the camera has been described as an example, the application of the present invention is not limited to this, and it is needless to say that the present invention can be applied to an electronic device that has a battery storage chamber and can be connected to an external device as necessary. Nor.

[0016]

As described above, according to the present invention, a signal can be transferred between an external device and an electronic device in a state that the external device can be stored in the battery storage chamber and the external device is mounted in the battery storage chamber. Since it is now delivered, it is possible not only to prevent noise being dissipated outside because the electrical connection part is not exposed to the outside or to be superimposed on the external cable and enter the inside, Since no external force is applied to the connection part, it will not come off and the electrical connection will not be damaged, and there is no need for a special fixing device, and the entire device will be integrated, making it an easy-to-use external device. Can be provided.

In particular, the shape of at least a part of the external device is similar to that of the battery pack, and the part of the similar shape is housed in the battery storage chamber on the electronic device side, so that the entire combined body of the external device and the electronic device is Compactness can be realized.
