Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a disc-shaped information recording medium storage case, and particularly to a storage case for a disc-shaped information recording medium that can be identified and recognized by a reproducing apparatus while the recording medium remains in the reproducing apparatus. The present invention relates to a disc-shaped information recording medium storage case designed to increase the amount of related information, ie, sub-information.

Prior Art Conventionally, there are video discs in which television signals consisting of video and audio signals are recorded using intermittent pit strings, and audio signals that are pulse code modulated (paM) and recorded using intermittent pit strings similar to video discs. In devices that play disc-shaped information recording media (hereinafter referred to as discs) such as V-recorded audio discs, the track pitch is recorded at an extremely high density, so that the signal recording surface may be affected when the disc is handled. scratches and dust,
The disc is protected by being enclosed in a storage case to prevent direct contact with hands to avoid fingerprints, etc. When the storage case containing the disc is inserted into the playback device and pulled out, the disc In some cases, when a disc is inserted into a playback device and an empty storage case is inserted into a playback device loaded with a disc and then pulled out, the disc is collected into the storage case.

For this reason, in such disc playback devices, it is common to externally identify whether or not a disc is fully loaded (
It is difficult to identify whether the disc is installed in a state where it can be played, the first side (front side) or the second side (back side). It is difficult to identify whether the recorded edge number 411 of the loaded disc is a television signal or an audio signal from POML, and whether the audio signal is stereo or monaural. I had to look at the disc storage case to identify it.

Therefore, the present applicant has previously disclosed in Japanese Patent Application No. 55-11278 and Utility Application No. 55-408490 that a disc storage case is provided on the front side in the insertion direction, and the disc is removed from the storage case outside the playback device. By providing a notch at a predetermined position on the front end of the lid to prevent the disc from popping out, a microswitch in the playback device that is installed opposite the front end position of the disc that is held together with the disc when the disc is installed. We have proposed a storage case with a shape that allows only the microswitches facing the notch to be turned off and the others to be turned on to obtain the board surface detection and other 4IF signals based on the outputs of these microswitches.

According to the above-mentioned storage case, the type of secondary information for identification is determined by the number of notches formed in the lid, and on the other hand, the number of notches that can be formed in the lid is naturally limited due to the dimensions of the lid. The problem is that the type of secondary information ~'q that can be identified by the combination of the notch and the microswitch is not sufficient, and as it stands, the expansion of the field of use and application of the device is restricted. was there.

Means for Solving the Problems The object of the present invention is to provide a disk-shaped information recording medium storage case that solves the above-mentioned problem 81, which is detachably connected to the case body. A side information + IJ recording medium, in which sub information related to the disc-shaped information recording medium housed in the case body is recorded, is incorporated into the lid left inside the playback device, and further aberrations can be absorbed into the playback device. A group of contacts is provided to electrically connect the sub-information recording medium to the reproducing device in a held state.

By using the iEPROMs 20A and 20B, the operation of the playback device 26 can be controlled so that the playback device 26 sequentially plays back predetermined chapter portions of the disc 4, and the playback device i&26 can be used as a consumer device. In addition to being used as a device, it can also be used as a business device for games, education, etc.

It is believed that EEPROM 20A and 20B can be used to record various types of digital information, and can be expected to be used for business purposes.

Further, the sub-information recording medium may be of a size that can be incorporated within the thickness of the main body portion γ of the lid 30, and a RAM or the like may be used instead of the KKPROMs 20A and 20B in the above embodiment.

Furthermore, since the contact groups 22A and 2213 are provided to avoid the place where the identification notch of the rose 3 is formed, the lid 3 is not provided with the contact groups 22A and 22B. As shown by the two-dot chain line in FIGS. 2 and 3, it is also possible to have a configuration in which an identification notch is formed, so that the disc storage case I'! As shown by the two-dot chain line in FIG. 3, the conventional regenerator equipped with a microswitch can be used without any problem. Also, regarding the ρ1 regenerator 26, the fixed contact pieces 38A and 38B are used for identification. It is arranged to avoid the arrangement position of the microswitch, and it is also possible to have a configuration that includes both the fixed contact piece group and the identification microswitch. In this case, the contact group 22A, 22
Conventional disk storage cases with lids that do not have B can also be used without any problems.

Effects As described above, according to the disk-shaped information recorder storage case of the present invention, a greater variety of sub-information, for example, the stored disk-shaped information record, can be stored than in the conventional combination of lid notches. In addition to various information related to the medium, information for controlling the operation of the playback device can also be supplied to the playback device, and the playback device automatically performs operations in a predetermined order according to the disc-shaped information recording medium attached. It is also possible to operate the playback device in a specific manner, and it is possible to achieve improvements in the functions of the playback device, such as advertisements, etc.
