BACKGROUND OF THE INVENTION The present invention has a solid-state image sensor,
The present invention relates to a video camera device configured to output a video signal obtained by the solid-state image sensor.

[0002]

2. Description of the Related Art Heretofore, there has been proposed a video camera device configured to pick up an image formed by a taking lens or the like by using an image pickup tube or a solid-state image pickup element, that is, a so-called CCD. This video camera device outputs the video signal output from the image pickup tube or the like housed in the outer housing to an external device or records it on a recording medium such as a magnetic tape or an optical disk via a recording device. It is a thing.

By the way, in the above video camera device, a signal transmission cable is used to connect an electric circuit built in the outer casing and a circuit of an external device. The signal transmission cable is connected to a connector for connection provided on the outer side of the video camera device and is connected to an electric circuit of the video camera device. A device as shown in FIG. 9 is known as a video camera device having a connector for connecting such a signal transmission cable.

The video camera device 10 shown in FIG.
In No. 0, the connection connector 102 is provided at the rear portion of the side surface of the outer casing 101 with its connection end facing downward. This is to protect the connection end of the connection connector 102. The connection connector 102 is connected to a connection plug 104 provided at one end of a signal transmission cable 103 connected to an external circuit.

Then, the signal transmission cable 103 is connected to the video camera device 100 by the connection connector 102 so that the video camera device 100 and the external device are connected, and the audio signal and the video signal are transmitted together with the control signal. It

[0006]

By the way, as the signal transmission cable 103, a triaxial cable is generally used, and the diameter thereof is 3.5 to 14.5 mm, which is considerably thick. Since the cable has a large diameter as described above, the diameter of the connection plug 104 attached to one end of the signal transmission cable 103 is also large and large. Further, the load applied to the connection plug 104 is also increased in combination with the weight of the cable. Therefore, a considerable load is applied to the connection connector 102 to which the connection plug 104 of the signal transmission cable 103 is attached. Therefore, the connection connector 102 is surely connected to the connection plug 1 of the signal transmission cable 103.
It must be able to hold 04.

Further, in the video camera device 100 having the connection connector 102 as described above, a finger or the like for holding the connection plug 104 when the signal transmission cable 103 is attached to or detached from the connection connector 102. It is necessary to secure the part where Therefore, a concave portion 105 having a large peripheral portion must be provided on the side surface portion of the outer housing 101 as a connector portion of the video camera device 100. Therefore, it is difficult to install it in the same place as other connectors, which causes inconvenience in operation, and
This is a cause of deteriorating the space efficiency on the outer casing 101.

Further, although the signal transmission cable 103 has a certain degree of flexibility, since its diameter is large, the cable can be bent only by drawing a large arc. Therefore, in order to place the video camera device 100 on the installation surface with the signal transmission cable 103 attached to the connection connector 102 fixed downward on the video camera device 100 as described above, the cable connection position is required. It is necessary to provide the installation position of the connection connector 102 above the video camera device 100, and there is also a problem that the height of the entire device cannot be kept low.

Therefore, the present invention has been proposed in view of the above-mentioned circumstances, and provides a connection connector which can be securely fixed at the time of attachment, but can be easily attached / detached at the time of attachment / detachment, and is space efficient. It is an object to provide a video camera device having the same.

[0010]

In order to solve the above problems and achieve the above objects, a video camera device according to the present invention includes an outer housing in which a solid-state image pickup device and an electric circuit are housed.
And a connection connector to which a signal transmission cable for connecting the electric circuit to an external circuit is connected, the connection connector being disposed on an outer side portion of the outer casing, and the connection connector being at least orthogonal to the outer casing in a biaxial rotation direction. It is attached so as to be rotatable.

Further, in the case where a connection connector portion to which a signal transmission cable for connecting the electric circuit to the external circuit is connected is provided on the outer side of the outer housing accommodating the solid-state image pickup device and the electric circuit, the connection connector described above. The section has a flexible internal cable electrically connected to an electric circuit built in the outer casing, and a connection connector attached to a tip end side of the internal cable and connected to a signal transmission cable,
A shield member that covers the internal cable, and a connector mounting member that is provided on the proximal end side of the connection connector and that enables the connection connector to be attached to and detached from the outer portion of the outer housing, and is provided on one side of the outer housing. The connector mounting member of the connecting connector portion is detachably mounted in the mounting hole, and when the connector mounting member is removed from the mounting hole, a part of the internal cable is pulled out from the outer casing to connect the connector. The connection direction of the connector may be changeable.

[0012]

In the video camera device according to the present invention, the signal transmission cable can be connected to the connection connector which is attached so as to be rotatable about the two axes that are at least orthogonal to the outer casing. Connection of the signal transmission cable becomes easy.

Further, when the connector mounting member of the connecting connector portion is made attachable to and detachable from the mounting hole provided on one side of the outer casing, the connector mounting member is removed from the mounting hole and the inner cable of the internal cable is removed. By pulling the portion out of the outer housing, the connection direction of the connection connector can be changed, and the signal transmission cable can be easily connected to the connection connector portion.
