Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a learning magnetic recording and reproducing device particularly suitable for early childhood education.

In recent years, the front side of the card has learning content such as multiple independent pictures of animals written on it, and the back side has multiple magnetic tracks recording audio that corresponds to the learning content on the front side, and the card can be played on a magnetic playback device. Devices that are inserted into a predetermined position and pressed with a finger on one of the learning contents will play a sound corresponding to that learning content, and devices that use this to educate young children have been developed and are beginning to be used. When targeted at young children, there were problems in ensuring that the system operated reliably and in making it easy for children to understand which learning content was instructed.

In view of such circumstances, the present invention has been developed so that when learning cards are set in the main body of the device, each learning content is separated by a plurality of windows provided in the main body of the device, and no matter which part of each seat is pressed, it is possible to reliably record or play back. When the switch is turned on, only the lighting device installed in the window that was pressed first lights up to indicate that specific learning content is being recorded or played. DESCRIPTION OF THE PREFERRED EMBODIMENTS Although the present invention is intended to provide a magnetic recording and reproducing apparatus, a case in which the present invention is configured for reproduction only will be described based on an illustrated embodiment.

1 is a plurality of movable windows IA on the top wall as described later.

1B, 1C, 1D, a power switch 1a, a card insertion slot 1b, a speaker window 1c, an earphone jack 1d, etc. on the side wall, and a main body case 2 in which a magnetic playback device, a drive device, etc., which will be described later, are housed inside. On the front side, for example, visual learning contents 2A, 2B, 2C, and 2D consisting of mutually different patterns and English words corresponding to those patterns are separately described, and although not shown, on the back side, each learning content 2A, 2B, 2C, and 2D are respectively provided with magnetic tracks spaced apart in an arc shape on which audio, etc. corresponding to 2B, 2C, and 2D are pre-recorded, and the card is inserted into the main body case 1 to a predetermined position through the card insertion slot 1b. Each learning content 2A, 2B, 2C
and 2D are window IA respectively.

This is a learning card that is aligned with IB, IC, and 1D, and each magnetic track is aligned with each of the movement trajectories of four reproducing heads, which will be described later.

The windows IA, IB, IC, and 1D all have the same structure, but the details thereof will be explained using FIGS. 2 and 3, taking the window 1A as an example. Directly below, a dish-shaped window frame body 3 with lenses made of a transparent material such as acrylic resin is attached so as to be movable up and down.

4a, 4a' and 4a'' are the flange 3a of the window frame body 3 and the partition wall 5.
These are normally open type switches which are interposed between the lens part 3b and arranged at equal intervals around the lens part 3b, and which are closed and closed when the window frame body 3 is pressed. It has the role of activating.

6a is a notch 3a provided in the flange 3a of the window frame body 3;
It is a lighting device such as a lamp or a light emitting diode housed in the interior, and includes switches 4a, 4a' and 4a" as described below.
When any one of them is closed and the operation holding device is activated, the light is turned on and the entire window frame body 3 is illuminated.

In addition, in other windows IB, 1C, and ID, normally open switches 4b, 4b', and 4b'', 4c, 4C', and 40'', 4
It goes without saying that the lighting devices 6b and 6C26d are also placed in the lighting devices d, 4d' and 4d'', respectively.

In FIG. 4, 7a, 7b, 7c, and γd are reproduction heads disposed on a turntable 8 (see FIG. 3) that is rotated by a drive device; g a , 9 b t
9c and 9d are provided corresponding to each seat IA, 1B, IC and 1D, and switches 4a and 4a'
and 4a", 4b and 4b' and 4b", 4C and 4 c/and 4
As soon as 0", 4d, 4d' and 4d" are closed, even for a moment, each seat IA, ID starts operating.

Operation holding devices 10 are operation holding devices 9a and 9b that hold the regeneration circuit, drive circuit, and lighting circuit corresponding to 1C and 1D in a closed state and stop their operation only when the operation of the motor rotation holding device described below stops. , 9c and 9d, it immediately disables all other operation holding devices and returns them to the original operable state when no input is received (selection device, 11). When there is an input from any one of the operation holding devices 9a, 9b, 9c, and 9d, the operation starts, and the turntable 8 is rotated by rotating a motor (to be described later), and the turntable 8 is rotated by a predetermined angle. 12 is a motor for rotating the turntable 8; 13 is an equalizer amplifier; 14;
15 is a power amplifier, 15 is a speaker, 16 is a headphone, 17 is a changeover switch, and 18 is a power source.

Since this device is configured as described above, first turn on the power switch 1a, then insert the learning card 2 from the card insertion slot 1b as shown by the arrow in FIG. When set in the position, each learning content 2
A, 2B, 2C and 2D are windows IA, IB, IC and 1D
windows IA, 1B, 1C and 1D by matching respectively
At the same time, each learning content appears slightly enlarged on each seat, while each magnetic track is separated by a reproducing head 7a,
7b, 7c and 7d, respectively, and the device is ready for operation.

Here, for example, if you press the window frame body 3 of the window 1A with your finger, even if it is not the center of the window frame body 3 (even if you press an uneven part, the switches 4a, 4a' and 4a"
are arranged at equal intervals around the lens portion 3b of the window frame body 3, so that any one of the switches 4a, 4a' and 4a'' is always closed and the operation holding device 9a starts operating immediately.

Then, a reproduction circuit consisting of the reproduction head 7a, the operation holding device 9a, the equalizer amplifier 13, the power amplifier 14, the speaker 15 or headphone 16, the power source 18, and the motor 12, the operation holding device 9a, the motor rotation holding device 11,
Since a drive circuit consisting of a power source 18 is formed, the turntable 8 rotates and only the reproduction head 7a picks up the audio recorded on the magnetic track, and this audio is reproduced by the speaker 15 or headphone 16. .

Since this audio is an explanation of the learning content 2A appearing on the window 1A and the pronunciation of the words, audiovisual learning is achieved here.

On the other hand, during this audio reproduction, the lighting device 6a-operation holding device 9a
- Since a lighting circuit including a power source 18 is also formed, the lighting device 6a lights up to brighten the entire window frame 3 of the window 1A.

Thus, when the turntable 8 rotates by a predetermined angle, the motor rotation holding device 11 automatically stops operating and the operation holding device 9a stops operating, and as a result, the reproduction circuit, drive circuit, and lighting circuit are opened. The rotation of the return turntable 80 is stopped, the audio reproduction is also stopped, and the illumination device 6a is also turned off.

In this way, one playback operation is completed, but this series of operations is performed in the same way when any of the other windows IB, IC, and 1D is pressed with a finger, and the respective learning contents 2B, 2C, and 2 are
The audio corresponding to D is played correctly and each seat 1B
, IC and 1D are illuminated.

In addition, since this device has a selection device 10, even if all seats are pressed at the same time or other windows are pressed while the window is in operation, only the operation holding device corresponding to the earliest window will be activated. However, the sound will play correctly and only the first window you press will be illuminated.

The above description has been made of the case where the principle of the present invention is configured as a playback-only device, but instead of the playback head group, a recording/playback head group and an erase head group are attached to the turntable 8, and a microphone plug is inserted into jack 1d. At the same time, if the playback circuit is switched to a recording circuit (not shown), this device can also be used as a recording device.

As described above, according to the present invention, when learning cards with a plurality of learning contents written on them are set, each learning content is separated by the plurality of windows provided in the main body of the device, and no matter which part of each seat is pressed, the learning contents are separated. When the recording or playback switch is turned on, only the lighting device installed in the window that is pressed first lights up to indicate that the specific learning content is being recorded or played back. Therefore, even when targeting young children, the device can be operated reliably and the learning content can be easily understood, making it possible to further improve the learning effect compared to conventional devices of this type. .
