DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a display device used in CD/cassette tape recorders, stereo devices, and the like.

2. Description of the Related Art In recent years, CD/cassette tape recorders and stereo devices have become widespread, and with the spread of microcomputers, more convenient and easy-to-use devices have been developed.

Conventionally, CD/cassette table recorders and stereo equipment have one dedicated display for displaying the elapsed time of the CD, the playback track number, etc., and another one for displaying the tape count value of the tape recorder. A dedicated display was installed.

Problems to be Solved by the Invention However, the conventional configuration requires separate displays for CD display and tape count display, which is expensive. The display was unnecessary and an eyesore. Also, if you play a CD and record music signals etc. on the tape, and try to write the tape count value corresponding to the recording start position of each music signal in the index of the cassette, you can check the track number on the CD display. However, on the other hand, the tape count value had to be checked on a separate display for tape count, making it extremely inconvenient to use.

In view of the above problems, the present invention is an inexpensive and simple display device that is extremely easy to use by displaying the CD time, track number, and tape count value as needed on the same display. It provides:

Means for Solving the Problems In order to solve the above problems, the display device of the present invention comprises a plurality of functional means such as a magnetic tape recording and reproducing means, an optical disk reproducing means, and one display device for displaying the plurality of functions. A display means, a display switching means for switching the content displayed on the display means, a tape count counting means for counting a tape count value corresponding to the amount of tape travel, and a control for mutually controlling the plurality of means. It has the structure of a means.

Effects With the above-described configuration, the present invention displays only optical disc-related information such as the time and track number of the optical disc when only the optical disc is being played, and displays tape count values, etc. when playing the magnetic tape. When the optical disk is being played back and music signals etc. are being recorded on the magnetic tape, the display switching means and the control means display the tape count counting means instead of displaying the time information of the optical disk. The count value is switched and displayed, and the playback track number of the optical disk is also displayed on the same display means at the same time. Therefore, while playing a CD or magnetic tape, only the minimum necessary display contents are displayed, and when the CD is When you want to record music signals etc. on a tape by playing it back, and write the tape count value corresponding to the recording start position of each music signal in the index of the cassette, the track number of the CD and the tape count value are displayed on the same display. This makes it extremely easy to use for users.
