Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a playback device suitable for application to games such as Ogura Hyakunin Isshu and Iroha Garuta.

Conventionally, a tape recording of Ogura Hyakunin Isshu has already been proposed, but if you play a game using this pre-recorded tape, the recording order of Ogura Hyakunin Isshu will become known in advance as you play the game many times. The fun of Ogura Hyakunin Isshu, which allows you to enjoy the random nature of the songs, is reduced by half because you don't know what the next song will be recited.

In view of this, the present invention aims to propose a playback device which, when applied to Ogura Hyakunin Isshu, does not impair the fun of enjoying the coincidence of the song recited without prior knowledge of the song recited subsequently. It is something to do.

An embodiment of the reproducing apparatus according to the present invention will be described in detail below with reference to FIGS. 1 and 2.

In Fig. 1, 1 is a magnetic tape on which each song of the Ogura Hyakunin Isshu that has already been proposed is recorded sequentially from the beginning, 2 is a magnetic head for reproducing the same, and 3 is a non-signal part of magnetic tape 1 (so-called between songs). 4 is a rotation detection circuit for the reel stand, 5 is a so-called numeric keypad, 6 is a central processing unit (CPU), 7
8 is a tape recorder main body, and 8 is a display device.
In addition, the tape 1 attached to this tape recorder body
For example, it is assumed that the poems of Ogura Hyakunin Isshu are recorded sequentially, that is, 100 poems, and a predetermined blank time is provided between each song.

A circuit 3 for detecting a non-signal portion of the magnetic tape 1 is composed of a reproduction amplifier 20, a rectifying diode 21, a smoothing circuit comprising a capacitor 22 and a resistor 23, and an amplifier 24. Further, the rotation detection circuit 4 of the reel stand includes a magnetizing disk 25 that is rotationally integrally attached to the reel stand, a reed switch 26 arranged close to the magnetizing disk 25, and a connection between the power supply +B and the ground. A resistor 27 and a capacitor 28 connected to
A series circuit consisting of a resistor 29, a diode 30,
It is composed of a smoothing capacitor 31 and an amplifier 32. In addition, reed switch 26, resistor 27,
The capacitor 28 and the resistor 29 constitute a so-called charging/discharging circuit. In the central processing unit (CPU) 6, 9 is a random number generator that generates an integer n (1, 2, 3...), and 11 is a RAM (random access memory).
The first memory 12, which stores one integer from 1 to n, is a RAM, and has m addresses (m ₁ ,
a second memory having a storage capacity of m ₂ ...address);
14 and 15 are the first and second registers, 13 is the first
and a comparison circuit that compares the outputs of the second registers 14 and 15, and 10 is a control circuit. This control circuit 10 transmits control signals between a random number generator 9, first and second memories 11 and 12, a comparison circuit 13, a tape recorder 7, a rotation detection circuit 4, a no-signal detection circuit 3, and a numeric keypad 5. Give and receive. Further, in the tape recorder 7, 16 is a fast forward mechanism, 17 is a rewind mechanism, 18 is a playback mechanism, and 19 is a stop mechanism.

FIG. 2 is a flow chart for explaining the operation of the system diagram shown in FIG. 1, and the configuration and operation will be explained with reference to this flow chart as well.

First, turn on the power switch (Power) on the numeric keypad 5, and operate the clear key C to clear the stored contents of all memories and all registers to "0". Next, operate the number keys "1", "2"..."0" on the numeric keypad 5 to access the central processing unit 6.
The upper limit value of the integer random number n obtained in the random number generator 9 is set to a predetermined value, in this case 100 corresponding to 100 poems of Ogura Hyakunin Isshu. (Thus, m (maximum value) of the second memory 12 may also be selected as 100.) At this time, a control signal is supplied from the control circuit 10 in the central processing unit 6 to the rewinding mechanism 17 of the tape recorder 7. Alternatively, the tape recorder 7 may be manually controlled to rewind the tape. Next, tape recorder 7
By detecting that the rotation of the reel stand (not shown) has stopped in the reel stand rotation detection circuit 4 and giving this detection signal to the control circuit 10, the control circuit 10 can also cause the tape recorder 7 to stop. A stop signal is supplied to the mechanism 19 and the tape recorder 7
to stop. (In other words, set the tape to the first start position.) Next, turn on the play start switch (Play Start) on the numeric keypad 5, and as a result, the random number generator 9 in the central processing unit 6 starts. A random number generation operation is started to randomly generate one integer random number n, and this integer n is stored in the first memory 11.
to be memorized. Now, let this numerical value n be _n41 . This numerical value is simultaneously loaded into the corresponding address m (in this example, address _m41 ) of the second memory 12. Then, it is determined whether the information at address m ₄₁ of the second memory 12 is 0 or 1, that is, whether the last one has been loaded or not. If the information at address m ₄₁ is 1, it is again The random number generator 9 generates an integer n (for example
n ₂₈ ) and read the information at address m ₂₈ in the second memory 12 in the same manner as described above, and if this is 0, the numerical value stored in the first memory 11 is stored in the second register 15. At the same time, information 1 is stored in the second memory 12 at address _m28 .

On the other hand, when the tape 1 is in the fast forward and rewind state, the detection circuit 3 detects the so-called song interval of the signal recorded on the tape 1 and supplies this to the first register 14, while the tape recorder main body 7 is in the fast forward state. The control circuit 10 detects whether there is a rewind or is in a rewind state and supplies this to the first register 14. Detect whether it is the th one. Therefore, this first register 14
As such, a reversible counter can be used.
The numerical value counted in the first register 14 in this manner is assumed to be k (k ₁ , k ₂ , k _{3 .} . . ).

The first register 14 counted in this way
The comparison circuit 13 compares the numerical value stored in the second register 15 as described above, and as a result, when k=n (in this case k ₂₈ =n ₂₈ ), the control circuit 10 The reproducing mechanism 18 is controlled by the signal from the input signal, and the tape recorder main body 7 is brought into a reproducing state.

Moreover, as a result of the comparison by the comparison circuit 13 mentioned above, k=
When n, the fast-forward mechanism 16 is controlled to put the tape recorder main body 7 into the fast-forward state, and when k=n is obtained in the comparator circuit 13, the playback mechanism 18 is switched and controlled to put the tape recorder main body 7 into the playback state. Eggplant.

Furthermore, as a result of the comparison by the comparison circuit 13 described above, k
=n, the rewinding mechanism 17 is controlled to put the tape recorder main body 7 in the rewinding state, and the comparison circuit 13
When k=n is obtained, the reproducing mechanism 18 is switched and the tape recorder main body 7 is placed in a reproducing state.

In this way, the tape recorder main body 7 enters the playback state, so that the data is recorded on the tape 1.
n ₂₈ , that is, the 28th song in this case, is played in the normal state (this playing means is omitted), and you can enjoy playing Ogura Hyakunin Isshu.

In this way, when the reproduction of one song is completed, a signal is obtained from the control circuit 10 based on the detection of the no-signal state in the detection circuit 3,
As a result, the stop mechanism 19 is controlled, and the tape recorder main body 7 is brought to a stopped state.

Thus, by operating the play start button on the numeric keypad 5 again, the above-mentioned operation is repeated.
Therefore, one hundred songs recorded on tape 1 can be randomly selected and played back one by one.

As the songs are played back one by one in this way, information 1 is stored in the second memory 12 in sequence for the addresses corresponding to the addresses of the songs played, and the information for all addresses is stored in the second memory 12. The above-mentioned operation is repeated until the number becomes 1. If the information of all addresses becomes 1, the tape recorder main body 7 is brought to a complete stop state or a display thereof is made.

In this way, according to the playback device of the present invention, it is possible to play the game of Ogura Hyakunin Isshu without knowing in advance which song will be recited next, and without losing the fun of enjoying the randomness of the songs to be recited.

Furthermore, even if there is one less person playing the Ogura Hyakunin Isshu game, or if the player is not good at continuing the game and wants a replacement, the game can be played without any hindrance.
