Description

[Detailed Description of the Invention] The present invention relates to an improved structure of a card travel drive device in a magnetic card recording and reproducing device, and the present invention relates to an improved structure of a card travel drive device in a magnetic card recording and reproducing device, and the reciprocating travel of the card is arbitrarily controlled to enable the card to repeatedly record and reproduce the button. The purpose is to make it possible to remove or replace it freely.

In general, devices of this kind are known in which the card is driven from one side to perform recording and playback, and then is automatically driven back from the other side to its original position to perform recording and playback again, or to be removed.

However, in these devices, the running drive of the card is controlled regularly and within a preset time period, so it may be necessary to replace the card midway through recording/playback due to the insertion of an undesired card, or to restart the drive midway through recording/playback. In some cases, it may be necessary to play the recording again, or to remove it, or to perform various combinations of these operations.Especially in the case of learning devices for early childhood education, it is difficult to give independence to young children. In order to make children more interested in learning, it is convenient to freely control the movement of the cards, and in this case, it is necessary to make the above operations possible with a simple structure.

The present invention has been constructed with attention to the above problem, and one embodiment thereof will be described in detail below based on the accompanying drawings.

In the drawings, reference numeral 1 is a magnetic card with a magnetic band (not shown) attached to the lower part of the card in the longitudinal direction, and letters and pictures corresponding to the meaning of the words recorded and played back on the magnetic band on the flat part. is formed.

Reference numeral 2 denotes a magnetic head that performs recording and reproduction by piezoelectrically applying piezoelectricity to the magnetic band of the card 1. Reference numeral 3 denotes a roller that faces the head 2, presses against the flat surface of the card 1, and drives one run.

4 is a running path for the card 1 formed including the opposing gap between the roller 3 and the head 2; 5 and 6 are running paths; The first . The second switch 7 is a three-circuit, two-contact switch, which has three interlocking movable contact groups 7a, 7b, 7c, one fixed contact group 7d, 7e, 7f selectively connected to this, and the other fixed contact group 7d, 7e, 7f. It is formed from fixed contact groups 7g, 7hs7x, movable contacts 7a and 7b, fixed contacts 7e and 71, and 7h and 7f.
are fixedly connected to each other.

Reference numeral 8 denotes a power source, the anode of which is connected to one terminal 5a of the first switch 5, and the negative electrode thereof to the movable contact 7c of the three-circuit, two-contact switch 7.

The other terminal 5b of the first switch 5 is connected to a fixed contact 7d of a three-circuit, two-contact switch 7.

9 is a motor that rotationally drives the roller 3, one terminal 9a is connected to the connection point between the fixed contacts 7e and 71 of the switch 7, and the other terminal 9b is connected to the fixed contact 7 of the switch 7.
They are respectively connected to the connection points of h and 7f.

One terminal 6a of the second switch 6 is connected to the anode of the power source 8, and the other terminal 6b is connected to the fixed contact 1g of the switch 7.

Here, in the case shown in the figure, the movable contacts 7a, 7b, 7c of the 3-circuit 2-contact switch 7 are connected to one fixed contact 7d,
It is in constant elastic contact with 7e and 7f and constitutes the device of the present invention.

The operation in the above configuration will be explained.

Now, when the magnetic card 1 is inserted into the running path 4 from the direction of the arrow, the card 1 presses the first switch 5 with its end face to close it, and connects the anode of the power source 8 to the terminal 5 of the switch 5.
a s 5 b y 3 circuit 2 fixed contacts 7d, iu'' of the contact switch 7, moving contacts 7a, 7b, fixed contacts 7e, terminals 9a, 9b of the motor 9, fixed contacts 7 of the above switch 7
f, i5T moving contact 7c is energized with the negative pole of the power source 8, and the motor 9 rotates.

Accordingly, the roller 3 rotates, and the card 1 is driven to run to the left in the drawing, and the magnetic head 2 performs recording and reproduction.

As the card 1 runs, the card 1 contacts the second switch 6 and closes it. However, since the fixed contact 7g and the movable contact 1a of the 3-circuit 2-contact switch 7 are open, the card 1 is connected to the power supply 8. The circuit holds the open command state and the bird,
The card 1 still continues to run to the left in the drawing, and when the card 1 leaves the roller 3, it becomes possible to pull the card 1 out of the running path 4.

When the card 1 contacts the second switch 6 and closes it, the movable contact 7a of the 3-circuit 2-contact switch 7 is closed.
g, the other movable contacts 7b and 70 are linked and connected to the fixed contacts 7h and 7i, and thereby the power source 8
From the anode to the terminals 6a and 6b of the second switch 6, the fixed contact 7g of the switch 7, the i'iT moving contacts 7a and 7b, the fixed contact 7h, the terminals 9b and 9a of the motor 9, the fixed contact 7i of the switch 7, Electricity is applied to the movable contact 7c and the negative pole of the power source 8, and the motor 9 is rotated in the reverse direction, thereby causing the roller 3 to rotate in the opposite direction and allowing the card 1 to return to its original position.

Then, when the card 1 comes into contact with the first switch 5, the switch 7 is opened, thereby making the movable contacts 7a, 7b, 7c
can be automatically returned to contact with the fixed contacts 7d, 7e, and 7f by elastic action, and it is possible to record and play back the card 1 again, and it is also possible to pull out and remove the IT card 1. can.

Therefore, the first. By setting the arrangement positions of the second switches 5 and 6, that is, by setting the distance between them through the magnetic head 2, the card 1 can be freely operated by a simple operation by selectively opening and closing the switch 7, no matter where the card 1 is in the travel path 4. In particular, in the case of learning devices for early childhood education, it is possible to fully satisfy the sudden and irregular requests of young children, and to improve the learning effect. can be improved.

As described in detail above, the present invention includes a magnetic head that records and reproduces information on a magnetic band formed on a card, and a roller that contacts the flat surface of the card to drive the card, which are disposed in the card travel path, and the magnetic head Opposing both sides through the middle,
First and second switches that are sequentially contacted and closed by the running of the card are arranged in the passage, and the first switch has three circuits and two switches.
One fixed contact group, one movable contact group, and the roller of the contact switch are connected to a motor that rotates the roller in one direction, and the second switch connects the other fixed contact group, the movable contact group, and the roller of the switch to the other. By connecting it to the motor that rotates, it is possible to easily and reliably control the travel of the magnetic card without complicating the circuit configuration.
In both cases, the movable contacts of the three-circuit, two-contact switch are normally closed by being in elastic contact with the fixed contacts of the switch connected to either the first switch or the second switch that drives the card to enable recording and playback. □This has the effect of making the operation even more convenient.
