Conventionally, in a recording / reproducing apparatus that records and reproduces an information signal using a tape as a recording medium, such as a video camera, for example, in addition to a material information signal including video, audio, and time, it is input by an external operation. Some information signals relating to the state of the device at the time of recording and the recorded video content can be recorded on the tape.
[0003]
However, this type of recording / reproducing apparatus performs multiplexing processing or data processing on the video signal or audio signal in order to record the information signal relating to the state of the recording apparatus and the recorded video content simultaneously with the recorded video. Functions are required, which increases costs. Also, when reproducing, since it can be taken out only in the order recorded on the tape, it is inconvenient that the information input by the external operation can be confirmed simultaneously with the material information or only the input information cannot be confirmed immediately.

In the above configuration, the arbitrary information signal acquisition unit includes a connection unit that connects to an external device, and a unit that acquires an information signal from the external device connected by the connection unit.
[0009]
According to this configuration, since electronic information created by a personal computer or the like is written in the memory, electronic information can be confirmed simultaneously or independently with video and audio during recording.
[0010]
The above-described configuration further includes a display device and display control means for displaying an information signal read from the memory by the memory access device on the display device.
[0011]

According to this configuration, since the user can grasp how much memory capacity is currently left based on the memory capacity information displayed on the display, various troubles due to memory fullness can be avoided. It becomes easy.
[0014]
In the above configuration, the memory access means selectively reads out an information signal combining the material information and the arbitrary information and a separate information signal, and the display control means operates in conjunction with the memory access means to transmit the material information and the arbitrary information. And a separate information signal are selectively displayed on a display.
[0015]
According to this configuration, for example, when the display screen of the display is small, it is difficult to see if a large amount of information is placed on the screen. Therefore, if the material information and arbitrary information can be selectively displayed by the user's selection, the user can check the information content recorded in the memory on an easy-to-view screen. Also, when it is desired to confirm only arbitrary information, it is possible to immediately read and confirm arbitrary information from the memory.
