Abstract

PURPOSE: To facilitate connection with an external apparatus by incorporating a mechanism for feeding/winding a signal connection cord and drawing out a signal connection cord having a male plug from the front part of a unit through the cord winding mechanism. CONSTITUTION: A signal connection plug 5 is drawn out from a plug containing part 7 or contained therein when a signal connection cord 6 is passed through a through hole 8. The signal connection cord 6 is drawn out from the plug containing part 7 together with a signal connection plug 5 and connected with the female signal input terminal of an external apparatus. The signal connection cord 6 is contained in a cord winding mechanism 10 through a stopper mechanism 9. Since the signal connection cord 6 can be adjusted to a connection length corresponding to the arrangement of the external apparatus and can be fixed at an adjusted position, it can be connected easily with the external apparatus without requiring any independent signal connection cord.

The present invention has been described above based on the embodiment used in the VTR device. However, the plug accommodating portion formed on the front panel has a structure which can be attached to and detached from the front panel as an adapter for the signal connecting plug. Needless to say, when connecting the signal connection plug to the female signal input / output terminal of the external device, the adapter can be used to protect the signal input / output terminal.

Further, since it is desirable that the signal connecting cord is separated as much as possible from the noise generating source such as the power supply circuit, the cord winding mechanism is arranged at the bottom of the VTR device so as to be superimposed on the signal connecting cord. The influence of noise can be reduced, and the internal space formed by other circuits of the VTR device can be implemented in the same manner as in the conventional case.

As described above, according to the present invention, in an AV device that records and reproduces an audio signal and a video signal and transmits these AV signals to an external device, the other end is connected to a signal input / output circuit inside the AV device main body. The signal connecting cord is fixed and has a male connecting terminal connected to one end, and a through hole is formed in the front of the AV equipment and the signal connecting cord is inserted in the inner part of the opening. Since the plug accommodating portion for accommodating the connection terminal of the mold and the cord winding mechanism for winding and accommodating the signal connecting cord provided on the bottom surface of the AV device are provided, the signal connecting cord can be arranged in the external device. The moving guide provided on the cord winding mechanism is slid with a corresponding pull-out length, and is pulled out from the front opening of the VTR device. Therefore, the signal connection cord can be directly connected to the female signal input / output terminal of the external device, so that the signal connection with the external device can be easily performed and the signal connection cord can be connected to the external device. The effect that there is no need to prepare separately.

Further, in an AV device which records and reproduces an audio signal and a video signal and transmits these AV signals to an external device, the other end is fixed to a signal input / output circuit inside the AV device main body and a male type is provided at one end. A signal connecting cord to which the connecting terminal is connected and a through hole that opens at the front of the AV device and through which the signal connecting cord is inserted are formed at the back of the opening.

Since the stopper mechanism for preventing the pulling in the direction opposite to the direction is provided, the connection length of the signal connecting cord can be appropriately adjusted by the stopper mechanism according to the connection length of the external device. Thus, there is an advantage that it is not necessary to prepare a plurality of signal connecting cords in accordance with the arrangement of the external device, and the disadvantage that the connection work with the external device is complicated and complicated is solved.
