Abstract

PURPOSE:To enable to optionally select and reproduce any one of playing cards or divination of games, by generating random numbers and implementing address signals from the random numbers. CONSTITUTION:A random number generator 12 generates random numbers and supplies them to an address signal producer 13. The address signal producer 13 produces address signals based on the supplied random numbers and supplies the produced address signals to a comparator 7. Upon receiving address signals from an operating device 9, the comparator compares the address signals with address signals from a signal reproducing circuit device and supplies difference signals obtained as the result of the comparison to a transferring device 5. The transferring device 5 moves a reproducing stylus to an assigned track position in accordance with the difference signal and performs linear tracking. Color TV signals thus obtained are subjected to demodulation, reproduction, and a prescribed signal processing at a video and sound reproducing circuit 8 and supplied to a monitor picture receiver 10.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating device for an information recording disk reproducing device, which generates random numbers and generates an address signal from the random numbers, so that it is possible to read each card of a card such as "Hyakunin Isshu" or the like. To provide an operating device for an information recording disk reproducing device that can select and reproduce each fortune-telling in a game such as a "fortune-telling game" completely arbitrarily.

Information recording disks such as video disks can be used for various purposes, and during playback, it is possible to arbitrarily select and play back one of a plurality of programs, that is, to perform random access.

On the other hand, there have conventionally been systems in which a karuku such as ``Hyakunin Isshu'' is read aloud and recorded on a tape, and the recorded tape is played back while the game is played without a reader. However, since it is not possible to change the reading order of the Calcs recorded on the audio tape and play them back, the Calcs are read out in the same order every time, and after a few times the players memorize the order, which detracts from the game's interest (2). There was a drawback.

The present invention eliminates the above drawbacks by using an information recording disk, and each embodiment thereof will be described below with reference to the drawings.

FIG. 1 shows a block system diagram of an embodiment of an information recording disc reproducing apparatus to which the present invention is applied. In the figure, reference numeral 1 denotes an information recording disk, which is placed on a turntable 2.

In the information recording disk, the main information signal is recorded as a frequency modulated wave on a spiral main track without forming a needle guide groove, and at a frequency lower than the recording frequency band of this frequency modulated wave, Burst-like first and second tracking control reference signals (hereinafter referred to as "tracking signals") f and f having different repetition frequencies;
. The switching connection 1 of , 2 has an electrode function in which the third tracking signal f, 3 is recorded on the main or sub-track (3) at a level below a predetermined level so as not to adversely affect the main information signal. In this information recording disk, a color television signal is recorded as the main information signal at a rate of 4 fields per revolution of the information recording disk. In addition, for example, in the 17th and 18th horizontal scanning period of the vertical blanking period of this color television signal, a time address indicating the time required for normal playback from the first recording program start position and a time address indicating the time required for normal playback from the first recording program start position, Address signals such as chapter addresses indicating the time required for normal reproduction from the program start position and the order of the recorded programs are recorded. Here, as an example, on the information recording disc 1, a color image corresponding to the famous song ``100 People Isshu'' and a color television signal of an audio signal reading out the song are recorded as the main information signal, respectively. The songs are assigned chapter addresses from "00" to "99" in order, and the number of programs on this information recording disk 1 is assigned to the outermost track in order of 100 (from roOJ to "99"). 100 chapters) and (4) program control signals are recorded.

The information recording disk 1 is placed on a turntable 2 and is rotated together with the turntable 2 by a motor 3 at, for example, 900 rp.
The regeneration needle 4 is synchronously rotated at m and is an example of a regeneration scanner.
The previously recorded signal is picked up and reproduced. The playback needle 4 is moved or stopped in the radial direction of the information recording disk 1 by a transfer device 5, and linearly tracks the track. The reproduction signal picked up and reproduced by the reproduction needle 4 is supplied to a signal reproduction circuit device 6.゛The signal reproducing circuit device 6 performs tracking 1) 1 using the tracking signals f, f, f included in the reproduced signal.
p2 1)3 A tracking error signal having a level corresponding to the amount of deviation and a polarity corresponding to the direction of tracking deviation is generated, and is supplied to the transfer device 5. Further, the chapter address (or time address) address signal is extracted from the main information signal in the reproduction signal and supplied to the comparison circuit 7, and the color television signal, which is the main information signal, is extracted from the video and audio reproduction circuit 8 ( 5) The program number is extracted from the program control signal and supplied to the operating device 9. Further, the comparison circuit 7 is supplied with an address signal of a chapter address (or time address) from an operating device 9, which will be described later. Comparison circuit 7
When the address signal is supplied from the operating device 9, the address signal is compared with the address signal from the signal reproducing circuit device, and the obtained difference signal is supplied to the transfer device 5. The transfer device 5 uses this difference signal to move the playback needle 4 in the radial direction of the information recording disk 1 so that the playback needle 4 plays back the track specified by the address signal from the operating device 9, and sets the chapter address (or time). - After the value of the difference signal is 0, that is, the playback stylus 4 has been moved to the designated track position, normal linear tracking is performed. The color television signal obtained in this way is demodulated and reproduced by the video/audio reproduction circuit 8 and a predetermined signal [
The signal is processed and converted into a television signal compliant with standard television formats. This television signal is supplied to the monitor receiver 10, where (6) it is reproduced on the monitor.

Next, a first embodiment of the operating device of the present invention will be described in more detail. The operating device 9 has a configuration as shown in FIG. In FIG. 2, reference numeral 11a is an input terminal, into which a random number generation pulse generated by pressing a random number generation key provided on the operation panel (not shown) of the information recording disc playback device enters, and this generates a random number. is supplied to the vessel 12. Also,
The information recording disk 1 is connected to the random number generator 12 from the input terminal 11b.
The number of programs is supplied, and when the random number generator 12 receives this random number generation pulse, it generates a two-digit random number when converted into a decimal number with the above number of programs from "00" to "99" as the upper limit, This random number is supplied to the address signal generator 13. The address signal generator 13 generates an address signal of a chapter address (or time address) using this random number as the chapter number (or time), and supplies this address signal from the output terminal 14 to the comparison circuit 7 shown in the first diagram. do. Therefore, from the monitor receiver 10 shown in FIG.
) can get. You can also press the random number generation key to get the next arbitrary number. However, the random number in this case is “00
” to “99”, so the same song can be played twice.
There is a possibility that 3 degrees or 3 degrees will be selected, which poses a problem.

FIG. 3 shows a block system diagram of a second embodiment of the device of the present invention that solves this problem. In this figure, the same parts as in FIG. 2 are designated by the same reference numerals, and their explanations will be omitted. In FIG. 3, random numbers generated by a random number generator 12 are supplied to a memory 5 and a comparison circuit 16.

Memory 5 has addresses 1 from ``00'' to ``99''.
This storage area has a storage area of 00 bits, and the storage area is cleared to zero when the information recording disk reproducing apparatus is powered on. The memory 5 moves the address pointer for writing and reading to the address indicated by the value of the supplied random number, reads out the memory contents at this address and supplies it to the random number generator 12 and the gate circuit 16, and then The stored contents of the address indicated by the address pointer are set to "1". The random number generator 12 is supplied from the memory 5 (8) When the memory content is "1", it generates a random number again and writes it to the memo IJ.
15, is supplied to the gate circuit 16, which closes when the stored content from the memory 15 is "O", and supplies the random number supplied from the random number generator 12 to the address signal generator 13 at this time. This prevents a song that has been played once from being repeatedly selected and played a second or third time. However, in this case, as the number of songs played once increases, the probability that the random number generated by the random number generator 12 will be the chapter number of a song that has not been played decreases, and the time required to select and play the next song decreases. A problem arises in that the distance becomes long.

FIG. 4 shows a block system diagram of a third embodiment of the device of the present invention that solves this problem. In the figure, the same parts as those in the circuit shown in the second figure are given the same reference numerals. In FIG. 4, a random number generation pulse coming from an input terminal 11 is supplied to a random number generator 12 and a counter 17.

The random number generator 12 thereby generates random numbers and supplies them to the arithmetic circuit 18 , and the counter 17 counts the random number generation pulses and supplies them to the arithmetic circuit 18 .

(9) Further, the program number is supplied to the arithmetic circuit 18 from the input terminal 11b, and the arithmetic circuit 18 inputs the value of the random number into R,
The count value of the counter 17 is n2, the maximum value of the generated random numbers is m (n, m, R are integers, n≦m, and in the case of 100 people isshu, m = 100), Surt, RI
-! l! An operation indicated by L-u+0.5 is performed, and the real part of the obtained value is supplied to the memory 19. Like the memory 15, the memory 19 has a 100-bit storage area from addresses "00" to "99", and the memory content at the address corresponding to the chapter number of the song that is not being played is "0". It has become. The memory 19 increments its address pointer, counts only when the stored content of the address indicated by the address pointer is "0", and continues to increment until this counted value becomes equal to the value supplied from the arithmetic circuit 18. carry out progress. At this time, the next address after address “99” is “OO”
Step forward to the address. After this increment, the memory 19 writes "1" to the address pointed to by the address pointer, reads this address as a random number, and sends it to the address signal generator 1.
Supply to 3. Here, the calculation performed at the calculation port (10) 18 is such that when the address pointer is incremented by an arbitrary number from "00" to "99" when 20 songs are played, for example, the memory 19 , the probability that an address will be pointed to where the memory content up to the 20th address after the address pointed to by the previous address pointer is 10 is that the other memory content is 10. ” higher than the address < 1. To live,
This is done so that any address whose memory content is "0" is uniformly selected. In this way, you can arbitrarily select and play a song that has not been played yet, and even if the number of unplayed songs is small, it can be played in approximately the same amount of time as when there are many songs. Possible and rl〇In addition, counter 17. The arithmetic circuit 18 is not necessarily necessary, and random numbers from the random number generator 17 may be directly supplied to the memory 19.

In the above embodiment, the user presses the random number generation key to generate a random number generation pulse, but this is automatically done at regular intervals after reproducing the program control signal recorded on the outermost track of the information recording disk 1. A configuration may also be used in which a random number generation pulse is generated. In addition, in the above embodiment, “
The explanation has been given using "Hyakunin Isshu" as an example, but this may also be "Iroha Karuku", etc., and in this case, the number of sheets of "Iroha Karuku" is recorded as the number of programs in the program control signal. Further, the device shown in the second figure is suitable for "fortune-telling games" and the like.

Note that the program control signal does not necessarily have to be recorded on the disc, and the user can manually input the one written on the disc case to the random number generator 12. Arithmetic circuit 1
You can also input 8.

The apparatuses shown in FIGS. 2, 3, and 4 can be controlled by a program using a microcomputer, and since it is easy for a person skilled in the art to create this program, the explanation thereof will be omitted.

The above explanation has been made regarding the information recording disc reproducing device proposed earlier by the present applicant, but it is also applicable to a device that reads and reproduces recorded signals using light such as a laser beam as a reproducing scanner instead of a reproducing needle. can also be applied.

As described above, the operating device for the information recording disk reproducing apparatus according to the present invention includes a random number generating means that generates a - random number every time a signal generated by a user or at regular intervals is supplied;
It consists of a generating means that uses the random number from the random number generating means to generate an address signal for searching the program recording position corresponding to the random number on the information recording disk. When a game such as ``Fortune Telling Game'' is recorded, each card of Calc or each fortune telling can be selected and played completely arbitrarily, and the user remembers this play order and can enjoy the game. Furthermore, the random number generation means has a memory for storing the generated random numbers, and any value from zero to the number of programs recorded on the information recording disk that is not yet stored in the memory. Since random numbers are generated, if calcs are recorded on the information recording disk, calcs that have been reproduced once will not be selectively reproduced again, which is advantageous.
