JPS60243896A - Reproducing device - Google Patents

Abstract

PURPOSE:To reduce the anxiety of a user so as to prevent misoperation of a reproducing device by providing a detection part that detects whether or not the picture information is recorded to a recording carrier and a display part and informing the user that a recording carrier to which the sounds only are recorded. CONSTITUTION:The signals recorded to a recording carrier 1 are converted into electric signals by a pickup 2. The sound and picture signals (a) and (b) are delivered after said electric signals are demodulated at a signal processing part 3. A detection part 4 detects whether or not the signal (b) is delivered among those signals demodulated at the part 3. The demodulated signals are not delivered to a display part 5 if they contain the signal (b) and delivered to the part 5 if no signal (b) is contained respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for playing back record carriers on which images and sounds can be recorded, such as compact discs, video discs, etc.

2. Description of the Related Art Structures of Conventional Examples and Their Problems In recent years, record carriers capable of recording images and audio, such as compact discs and video discs, have become widespread, and their playback devices have also been widely used.

A conventional playback device will be explained below.

FIG. 1 shows a conventional reproducing device, in which 1 is a record carrier, 2 is a pickup 3 for obtaining signals from the record carrier, and is a signal processing section for reproducing image signals and audio signals from the signals obtained from the pickup. .

A conventional playback device configured as described above will be described below.

A second pickup converts the signal recorded on the first record carrier into an electrical signal. Since this electrical signal is modulated in a manner convenient for recording on a record carrier, it does not become audio or image information as it is. This signal is demodulated by a signal processing section 3 and outputs an audio signal a and a video signal b.

Conventional configurations are designed to be record carriers that record both audio and 7 images, so a record carrier that has an area that can record both audio and 9 images but that only records audio can be used as a record carrier. During playback, an audio signal is output, but an image signal is not output, which has the problem of causing anxiety to the user.

Purpose of the Invention The present invention solves the above-mentioned conventional problems.
Detecting whether image information is recorded on the record carrier,
The purpose of the present invention is to provide a playback device that can display such information.

Structure of the Invention The present invention includes a detection unit that detects whether or not image information is recorded on a record carrier, and a display unit that displays the output of the detection unit. This feature is characterized by displaying the fact that the user has not done so, thereby informing the user of this fact, alleviating the user's anxiety and preventing erroneous operations.

DESCRIPTION OF EMBODIMENTS FIG. 2 shows an example of the configuration of a reproducing apparatus in an embodiment of the present invention. In FIG. 2, 1 is a record carrier, 2
3 is a pickup for obtaining a signal from the record carrier; 4 is a signal processing unit that reproduces image and audio signals from the received signal; 4 is a signal processing unit that determines whether the reproduced signal includes an image signal or not; It is a detection unit that detects , and is a 6-digit display.

Regarding the playback device of this embodiment configured as above,
The operation will be explained below.

A second pickup converts the signal recorded on the first record carrier into an electrical signal. Since this electrical signal is modulated in a manner convenient for recording on the record carrier, it does not become audio or image information in its current state. This signal is 3
The signal processing unit demodulates the signal and outputs the audio signal a and the image signal b.

4, a detection section detects whether or not an image signal is output from among the signals demodulated by the signal processing section. If the image signal is included, it is not output to the display, and if the image signal is not included, it is output to the display. Therefore, when the image signal is not reproduced, the user
By confirming that the light is lit, it can be clearly determined that the image signal is not actually distorted.

Effects of the Invention According to the present invention, the record carrier is equipped with a detection unit and a display device for detecting whether or not image information is recorded on the record carrier.
By displaying the fact that image information is not recorded, it is possible to provide an excellent reproduction device that can notify the user of this fact and alleviate the user's anxiety.
