detection means to detect an unloading completion is provided and as the power source is made off an unloading completion signal can be obtained from said detection means so that an unloading is automatically made thus its handling and operation can be made very easily further such arrangement is employed that power supply to circuits related to a loading is maintained even if the power source is made off until said unloading is completed and the power supply is automatically stopped by a completion of an unloading therefore a handling characteristic is further improved and power saving can be made without any particular efforts also in a video system of the present invention a vtr which is combined to a video camera for making a photographing is made of parts containing a recording mode only therefore a camera and a vtr is integrally made thus a reduction in size and weight can be achieved further since a vtr is made to have as small size as possible for having the minimum function needed solely for a recording when the vtr is combined with a video camera a burden on a user at a time of photographing can be reduced to the minimum thus a handling characteristic is further improved and it will be easy to carry the same around further as the camera is removed from the vtr the vtr is automatically changed over to a reproduction mode and it is combined with a reproduction unit so that a function in a reproduction mode can be obtained without delay thus it is a very convenient device as a simple video system also a vtr in.
