In this way, the sound source of the portable cassette tape player 16 and the like can be recorded together with the ambient sound when the video camera is shooting.

Here, the reason why the function of simultaneously recording the ambient sound and the sound of the portable cassette tape player will be described. Nowadays, with the widespread use of video cameras, it often happens that other people view the recorded video tapes. In this case, it is difficult and even painful to gaze at the TV screen for a long time if the viewer is not interested in it. Considering the difference between commonly recorded videotapes and televisions that have made drama into everyday life, it can be seen that BGM (background music) has a great influence.

[0004] Therefore, when a recorded videotape that is generally taken is edited and BGM is added to the sound, it can be seen even in a situation where the videotape is not very well taken. Also, the characters of the recorded videotape move according to the BGM. You can even feel like you are. However, in the case of only BGM without surrounding sounds, the screen lacks a sense of realism, and even if there is music, a sense of incongruity like that of an old silent movie will occur.

[0005]

From this point of view, when it is attempted to record the sound of the portable cassette tape player and the like at the same time as the sound of the surroundings, in the above-mentioned conventional apparatus, various kinds of apparatuses are connected by a cord.
