发明名称 AUDIO SERVICE DEVICE FOR VIDEO CAMERA
摘要 PURPOSE:To inform information such as residual amount of video tape with sound, by providing a storage section storing a sound code signal coded digitally for service and a sound control section reading out it. CONSTITUTION:When a start signal is inputted to an output control section 8, the output control section 8 instructs the information to be generated such as power supply voltage of a video camera and residual amount of the video tape to a sound control section 2. The section 2 reads out the sound code signal corresponding to the instructed information from a storage section 1. This sound signal is converted into an analog signal from a digital analog converting section 3 and inputted to a mixing section 4. A signal mixed with a video camera input signal is inputted to an electroacoustic converter 6 such as earphone via an amplifier section 5 and converted into sound output.
