Abstract

PURPOSE:To display clearly the information related to a recording/reproducing device by using a display means provided independently of the main body of the recording/reproducing device, a detection means which detects the loading state of a recording means to said main body and a control means which changes the display mode of the display means in response to the output given from the detection means. CONSTITUTION:When a recording medium 3 is not loaded yet, a detection means 11 delivers a signal to the 1st control means 12 to show that the medium 3 is no loaded yet. The means 12 delivers said signal to the 2nd control means 13, and the means 13 switches on and off all pilot lamps of a display means 17 at a time, for example, to perform an alarm display. Furthermore the means 17 receives no limitation of its size since it is provided independently of the main body 2. Thus the size of the means 17 can be increased up to such a level that is never overlooked. Then it is possible for an operator to confirm assuredly the loading state of the medium 3 and the information related to a reproducer. This improves the operability of a recording/reproducing device.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an information display device related to a recording/reproducing device that performs recording and/or reproduction using a recording medium.

BACKGROUND ART Recording/playback devices such as video disks have a disk attachment/detachment mechanism, and only when the video disk is attached to the main body can the video and audio signals recorded on the video disk be read in response to an operation by the operator. It's playing. In conventional video disc recording/playback devices, information related to the recording/playback device is displayed on a relatively small display unit IC of the recording/playback device. Information related to the recording/playback device includes information on whether the side of the video disc to be recorded/played is side A or side 8, and information on whether the video disc is inserted or not. , or information such as whether the video disc is in a stopped state or a playing state.

As mentioned above, since the display section that displays information related to the recording/playback device is relatively small, the operator often overlooks the display section, which may cause the recording/playback device to operate differently than the user intended. For the first time, I realized that I had made an operational error, such as not having a video disc installed. As described above, conventional recording/reproducing apparatuses have the disadvantage that it is easy to overlook the display section that displays information related to the recording/reproducing apparatus.

Object The object of the present invention is to provide a display device for a recording/reproducing device using a recording medium that can clearly display information related to the recording/reproducing device without overlooking it.

Embodiment The drawing is a block diagram of a playback device 1 according to an embodiment of the present invention. A reproducing device 1 uses a main body 2 to reproduce video signals and audio signals from a recording medium 3 realized by a magnetic disk on which video signals and audio signals are recorded. The display device 4 displays information related to the playback device 1. A magnetic head 5 included in the main body 2 detects video and audio signals recorded on the recording medium 3. The signal processing circuit 6 demodulates and reproduces the video signal and audio signal detected by the magnetic head 5. The signal processing circuit 6 moves the pickup 5 using a tracking servo circuit (not shown).

The video signal reproduced by the signal processing circuit 6 is displayed by the image display circuit 7. - The audio signal reproduced by the power signal processing circuit 6 is amplified by the audio amplification circuit 8 and outputted by the speakers 9 and 10. The detection means 11 detects information related to the playback device 1 . Information related to the playback device 1 includes information on whether the recording/playback side of the recording medium 3 is side A or side B, and whether the recording medium 3 is inserted into the playback device 1 or not. This information includes information on whether or not the recording method of the video signal recorded on the recording medium 3 is so-called NTSC/PAL or SECAM. Detection of information as to whether the recording/reproducing side of the recording medium 3 is side A or side B, or information as to whether the recording format of the recording medium 3 is NTSC/PAL or 5ECAN, can be performed by, for example, detecting It is detected by three microswitches provided in the means 11.

The recording medium 3 is provided with a notch that allows the above-mentioned states to be discriminated. The detection means 11 uses the three microswitches described above to detect a notch provided in the recording medium 3, and detects information related to the reproduction device 1 described above. Information detected by the detection means 11 is input to the first control means 12. First control means 12
controls the output of video signals and audio signals according to the information from the signal processing circuit 6, the detection means 11 and other circuits, and controls the transfer of information related to the main body 2 to the control means 13. Do the following. The display section 14 is the first
Information related to the playback device 1 is displayed in response to the output from the control means 12. The display section 14 is provided on the main body 2 and is relatively small, so it is often overlooked by the operator.

The operating means 15 includes a coin selection circuit 16, a display means 17, and a selection switch 18. The coin selection circuit 16 outputs a signal corresponding to the inserted coin by a coin detection switch (not shown) provided in the coin selection circuit 16. The coin reading circuit 19 reads the signal from the coin selection circuit 16 after removing chattering from the signal.

The coin collector 20 accumulates the signals from the coin reading circuit 19. When the amount accumulated in the coin counter 20 exceeds a predetermined amount, the second control means 13 reads a signal from the selection switch 18.

The selection switch 18 instructs reproduction of the recording medium 3, etc. The second control means 13 instructs the first control means 12 to reproduce in response to the operation from the selection switch 18. The first control means 12 activates the main body 2 and outputs the video signal, audio signal, etc. from the recording medium 3 to the image display circuit 7μ and the speakers 9 and 10. At this time, the second control means 1
3 controls the drive circuit 21 to control the blinking of the display means 17 and the like.

The specific operation of the playback device 1 will be explained below.

In the playback device 1, when the total amount of coins inserted into the coin selection circuit 16 is less than a predetermined amount, the control means 13 uses the drive circuit 21 to sequentially blink the display lamps of the display means 17, for example. let Coin selection circuit 16
When the total amount of coins inserted into the coins exceeds a predetermined amount, the second control stage 13 simultaneously lights up the display lamps of the display means 17, for example, and waits for selection of the selection switch 18. When the selection switch 18 instructing reproduction of the recording medium 3 is pressed, the main body 2 is activated and outputs the video signal and audio signal recorded on the recording medium 3. At this time, the second control means 13 lights only the display lamp of the display means 17 corresponding to the pressed selection switch 18, for example. When the playback of the recording medium 3 is finished,
The second control means 13 returns to the state of sequentially blinking the display lamps of the display means 17 as described above.

When the recording medium 3 is not installed, the detection means 11 outputs a signal indicating that the recording medium 3 is not installed to the first control means 12. The first control means 12 outputs a signal to the second control means 13 indicating that the recording medium 3 is not loaded. At this time, the second control means 13 performs a warning display such as, for example, causing all the display lamps of the display means 17 to flash simultaneously. Since the display means 17 is provided separately from the main body 2, there is no size restriction and it can be made large enough not to be overlooked. Therefore, by visually observing the display means 17, the operator can check the mounting state of the recording medium 3 and other information related to the playback device 1 without overlooking it, thereby improving operability.

In the above-mentioned embodiment, only the case where the recording medium 3 is reproduced has been described, but it is also possible to record the video signal and the audio signal on the recording medium 3.

Further, in the above embodiment, only the case where a video disk was used as the recording medium was described, but other recording media such as a magnetic disk or a video tape may be used.

Although the reproducing apparatus 1 of the above-described embodiment has only been described as a reproducing apparatus that operates using coins, the mechanism does not need to be a mechanism that operates using coins.

Although the display means 17 in the above-mentioned embodiments has been described only when an indicator lamp is used, other display means such as a liquid crystal may be used as long as the operator does not overlook it.

Effects As described above, according to the present invention, since the display means is provided separately from the main body, it is possible to make the display means large enough to avoid overlooking information related to the recording/reproducing device. It can be displayed clearly without any problems.
