Description

[Detailed Description of the Invention] According to the present invention, a large number of songs with different contents are distributed and recorded on a large number of cassette tapes, and by reserving 6 songs using an input device, the songs are automatically selected and played in sequence. This invention relates to an automatic music selection and playback device.

Traditionally, many songs with different contents are recorded on many cassette tapes, such as karaoke tapes, and in order to select and play the desired song from among these many cassettes, different song titles are recorded in advance. There is an automatic song selection/playback device that automatically selects a cassette tape containing a desired song and starts playing it by assigning a code number and specifying the code number using a push-button input device such as a numeric keypad.

Figure 1 shows a cassette storage drum 2 in which a cassette 1 can be rotated.
The cassettes 1 containing the desired songs are arranged in a circular shape with the tape side facing outward, and are rotated against a playback device equipped with a fixed magnetic head 3. This shows how the playback device is attached to the player and played.

In FIG. 2, a plurality of cassettes 1 are stored in a lattice-shaped storage shelf 5, and a playback device equipped with a magnetic head 3 moves vertically and horizontally to place the player's hand at the desired cassette position. 1 shows a method in which the cassette 1 is attached to the playback device and starts playing.

However, in both of the above two methods, only one playback device can be installed, so it takes a considerable amount of time to finish the currently playing song and select and start playing the next song. I used to be.

This is because the cassette storage drum 2 or the playback device 4 can only be moved after the currently playing song ends.

Therefore, when there are many songs and many people wishing to perform, such as in a karaoke club, there is a long waiting time until the next song is selected, which is extremely inconvenient.

The present invention has been made in view of the above circumstances.While one cassette is being played by one playback device, the next song to be played is reserved, and the next song containing the song to be played is reserved. Automatic song selection playback that reduces waiting time by attaching the current cassette to another playback device, keeping it on standby so that it can start playing at any time, and then playing the next song as soon as it finishes playing. The aim is to provide equipment.

A notch 30 is provided on the outer edge of the bottom plate of the cassette storage drum 13 for each cassette storage frame 18, and the cassettes can be stored in a manner such that the notch 30 corresponding to the storage frame 18 located directly below the playback devices 21a, 21b is sandwiched therebetween. Light projectors 31a, 31b and light receiving sensors 32a, 32b are provided for outputting electric signals for positioning the storage frame 18.

FIG. 6 is a perspective view showing the appearance of the input device.

In the figure, 33 is an input device, and its front upper panel 34 includes a numeric keypad 35 for inputting a series of code numbers for identifying the track and cassette number, and a digital display of the code numbers and reservation order. It is equipped with a display 36, a start switch 37, and a stop switch 38.

The lower front panel 39 is provided with a coin slot 4-0 and a cassette slot 4.1 for inserting an eight-track cassette.

A control circuit 2 is incorporated inside the input device 33, which generates various control signals and is connected to each electrical component of the automatic music selection/playback device 9 via a cord 43.

Next, the operation of the automatic music selection and playback device of the present invention will be explained.

It is assumed that initially no cassette is installed in either of the two playback devices 21a, 211). When the code numbers of the songs desired to be played are input in order using the numeric keypad 35 of the input device 33, the cassette number and priority order are temporarily stored in the control circuit 42.

First, the drive motor 11 rotates in order to move the cassette storage frame 18 containing the cassette number of the first priority to directly below the first playback device 21a.

At this time, a cutout 30 provided for each cassette storage frame 18
The drive motor 11 stops when the number of pulses emitted every time the pulse passes between the light projector 31a and the light receiving sensor 32a matches the cassette number.

Next, the motor 26a rotates in the direction in which the cassette push-up bar 23a rises, rotates the pinion 25a, and
Raise the cassette push-up bar 23& via a.

The upper end of the cassette push-up bar 23a passes through the square hole 19 and the cassette 1a is stored in the cassette storage frame 18.
is pushed up, and the cassette 1a is inserted into the square hole 20a of the support frame 10.
When the cassette la is inserted into the reproducing apparatus 21a through the cassette insertion opening 22a of the reproducing apparatus 21a and pushed in sufficiently, the cassette la is firmly attached to the reproducing apparatus 21a.

At this time, as the cassette push-up bar 23a rises, the protrusion 27a also rises, and the upper micro switch 29
a is activated, the motor 26a is stopped, and at the same time the motor 26a is activated.
The direction of the current flowing through 6a is reversed. After a certain timing, the motor 26a begins to rotate in the opposite direction, the cassette push-up bar 23a descends, and the protrusion 27a in turn activates the lower microswitch 28&, and the motor 26a stops. When it is confirmed that the cassette push-up bar 23 & has gone down completely, the playback device 21a moves the first cassette Za
begins to play.

Subsequently, the second cassette number stored in the control circuit 42 is called, and the drive motor 11 rotates while counting the number of notches 30 using the light emitter 31b and the light receiving sensor 32'b. It stops when it matches the number of differences between the second cassette number and the first cassette number.

When the cassette storage frame 18 with the second cassette number comes to a position right below the second playback device and stops, the motor 26b rotates in the same way and the cassette push-up bar 231) rises, pushing up the second cassette 1b and moving it to the playback device 211. ). When the cassette 1b has been installed, the motor 261) rotates in the opposite direction, the cassette push-up bar descends, and the protrusion 2
71) activates the lower micro switch 28b, this time the drive motor 11 is reversely rotated and the first cassette l-1a is rotated.
The drive motor 11 is rotated by the number of pulses counted when bringing the second cassette 1b directly below the reproducing apparatus 211) from the stopped position to insert the second cassette 1b into the reproducing apparatus 21a. Therefore, the cassette storage frame 18 in which the first cassette (1a) is to be stored returns to the position immediately below the playback device 21a.

Since the playback device 21a is still playing, the second playback device 21b is on standby so that it can start playing at any time, and the cassette storage drum 13 is also stopped and on standby.

When the playback device 21a finishes playing, the display 36 of the input device 33 displays the second cassette number and a signal indicating that it is ready to play, and the player presses the star 4° switch 37.
If you press , the second playback device will start playing.

On the other hand, the first playback device 21 & is the cassette which has finished playing.
Rewind a, return the beginning of the song to its original position, and press EJE.
When CT is performed, the cassette 1a falls downward from the cassette insertion slot 22a due to its own weight and is stored in the cassette storage frame 18.

Thereafter, similarly, the cassette with the third priority is attached to the first playback device 21a and placed on standby, and the cassette storage frame 18 into which the second cassette is placed is returned to just below the second playback device 21b, and the second cassette is placed in the second playback device 21b. The system waits until the cassette 1b finishes playing.

Since the present invention has the above-described configuration, while one playback device is playing a cassette tape, the input device selects a cassette containing another reserved song and plays another cassette tape. Since it is attached to a single playback device and is on standby ready to be played at any time, the waiting time between songs can be significantly shortened.
