Description

DETAILED DESCRIPTION OF THE INVENTION The present invention particularly relates to a learning device that is convenient for improving one's educational level by using both the auditory sense and, if necessary, the visual sense using a text book or the like. In general, conventional devices of this type record questions, answer explanations, and correct answers on a magnetic tape, and present the questions to the learner by running and playing them back with a magnetic recording/reproducing machine. The learner selects and closes the open/close switch prepared in advance in a number equal to the number of items in the answer explanation, and compares and judges the electrical signal generated by operating the switch with the electrical signal corresponding to the correct answer. It has a function to display correct or incorrect answers to questions. However, when a learner judges the presented problem and performs an answer operation after the problem is presented, the answer is judged the moment the switch is closed, and the judgment result is determined by the time the switch is closed. For example, if a learner closes the switch momentarily in a hurry to answer, the correct or incorrect information will be displayed only at the moment of closing.
If the learner does not pay close attention, they may miss something. For this reason, the learner has to check whether the switch is correct or not before opening the switch, and if the switch is closed momentarily by mistake, the learner may not be able to confirm whether the switch is correct or not and move on to the next new problem. This produced extremely inconvenient results. In the present invention, when an answer operation is performed while the question is being presented, the judgment is displayed for a certain period of time after the correct/false judgment is made, regardless of the closing time of the on/off switch, and if the answer operation is performed after the question is presented, a certain period of time elapses from the time of closing to the time of opening. By continuing to display the judgment until the end of the test, we have created a learning device that eliminates the troublesomeness of the learner's answer operation, and also makes it possible to reliably determine whether the answer to the question is correct or incorrect, and which can reliably improve the learning effect. This is what we provide. Embodiments of the present invention will be described in detail below based on the accompanying drawings.

In the above configuration, when an answer operation is performed while a question is being presented, the correct/incorrect display is displayed for a certain period of time immediately after the correct/incorrect judgment is completed, and in the case of an answer operation after the question presentation is performed, the correct/incorrect display is displayed continuously during the operation and for a certain period of time after the operation. The display operation will be explained using the time chart shown in FIG. Each operation below is assumed to be a positive logic (ie, H=1, L=0) signal. First, when the power supply 24 is turned on by a start switch (not shown), the transistor 22 in the magnetic recording/reproducing device 9 is in a conductive state, so the power supply 24 is applied to the drive motor 10, and the magnetic tape 1 is sequentially fed. First, the notification signal 4 on the track 2 of the magnetic tape 1 is reproduced by the magnetic head 12, and an audio signal amplified by the reproduction amplifier 14 is used to present the start of the problem to the learner from the speaker 17. At the same time, notification signal 4 is sent to track 3.
The response signal 7 recorded within the time band is input to the band filter circuit 26 of the signal shaping section 25 via the reproducing amplifier 15 and the relay contact 16 (2), and is shaped and amplified by the rectifier circuit 27 and amplifier 28. The resulting signal a is input to the input terminal of the S-R flip-flop circuit 31 via the delay circuit 29 and amplifier 30, and is also applied to the A input of the AND circuit 32. Next, at the falling edge of the first signal (i.e., answer signal 7) in the signal a, S-R
The Q output b of the flip-flop circuit 31 is inverted to the "H" state and is applied to the B input of the AND circuit 32 and the answer button 39 in the answer button section 38 . Here, the S-R flip-flop circuit 31
The Q output b maintains the "H" state until the Q output l of the retrigger mono multivibrator 58 in the correct/incorrect display section 54 becomes "H" and is applied as a reset signal to the reset terminal.
Only the rectified waveform of the correct answer signal 8 following the answer signal 7 appears at the output C of the AND circuit 32. thus
The correct answer signal C output from the AND circuit 32 is applied to the input terminal of the mono multivibrator 34 in the control section 33 and the A input of the AND circuit 35. The Q output of the mono multivibrator 34 becomes "H" from the fall of the first signal in the correct answer signal C, and is applied to the input terminal of the S-R flip-flop circuit 36 and the delay circuit 37. The output d of is delayed by a time equal to or less than the width of each pulse interval of the correct answer signal c, and is passed through the AND circuit 3.
5 is applied to the B input. Here, the signal d output from the mono multivibrator 34 and delayed by the delay circuit 37 maintains the "H" state at least for a period of time to ensure that the maximum number of correct answer signals is recorded within the time band. , AND circuit 35 outputs the second and subsequent correct answer signal pulses f excluding the first signal. Now, if the correct answer to one question is number 4, the correct answer signal 8 is composed of four signals. Here, in order to answer the question, the learner closes the answer button that is considered to be the correct answer among the plurality of answer buttons 39 in the answer button section 38 , but as mentioned above, when the question starts Answer signal 7 having the same time band as broadcast signal 4 that broadcasts
At the end of the notification, that is, at the same time as the end of the notification, the signal shaping unit 2
Q of the S-R flip-flop circuit 31 in 5
Since the output b is in the "H" state and applied to the answer button 39, for example, if the answer button 39 (4) corresponding to the correct answer to the question is closed while the question is being presented, the S-R flip-flop The "H" state is applied to the input terminal S of the circuit 40 (4) only for the time that the answer button 39 (4) is closed, and at the same time as this signal g rises, the S-R
The Q output h of the flip-flop circuit 40(4) is inverted from the "L" state to the "H" state, and remains at the "H" state until it is reset after the instruction signal 6 ends. At the same time, the output is maintained in the "L" state, and the answer ranking display lamp 42 (4) continues to be lit until the correct/incorrect determination is completed. Next, the Q output signal h of the S-R flip-flop circuit 40 (4) is applied to the input of the OR circuit 51 in the correctness determination section 48 and the A input of the AND circuit 49 (4). The output remains in the "H" state and is applied to the B input of the AND circuit 55 until the end of the application time, that is, after the instruction signal 6 ends when the S-R flip-flop circuit 40(4) is reset. Further, the output signal f of the AND circuit 35 in the control section 33 is applied to the clock input terminal CK of a JK flip-flop circuit 45 in a correct answer signal counting section 44 consisting of a well-known ring counter.
Here, the correct answer to the question is the fourth, and four signals are recorded in the correct answer signal 8, so
The output signal f of the AND circuit 35 is sequentially applied as three signal pulses to the clock input terminal CK of the J-K flip-flop circuit 45 by the above-mentioned logical product, and is sequentially applied as a ring counter constituted by the J-K flip-flop circuit 45. As a result, the J-K flip-flop circuit 4
Q output i of 5(3) is inverted to “H” state,
It is applied to the B input of the AND circuit 49(4). As mentioned above, at this point, the answer button 39(4) is already closed and the Q output h of the S-R flip-flop circuit 40(4) is in the "H" state, so the J-K flip-flop circuit 45
At the same time as the Q output i of (3) is inverted to the "H" state, the output of the AND circuit 49 (4) is inverted to the "H" state by logical product, and the correct answer OR circuit 5
The output j of 2 is also inverted to the "H" state and is applied to the B input of the AND circuit 56. Immediately after the instruction signal 6 ends, the output of the S-R flip-flop circuit 36 in the control unit 33 is inverted to the "L" state, the transistor 22 is cut off via the inverter 23, the drive motor 10 is stopped, and at the same time the Q output is output. e is inverted to the “H” state, and A of the AND circuit 55
However, since the B input is already in the "H" state, at the same time as the Q output e is inverted to the "H" state, the output k of the AND circuit 55 is inverted to the "H" state. , is applied to the input terminal T of the retrigger monomultivibrator 58. Furthermore, S
The Q output e of the -R flip-flop circuit 36 is applied to the inverter 59, and the response lamp 60 is turned on until the output l of the retrigger monomultivibrator 58 falls. Here, the Q output l of the retrigger mono multivibrator 58 is inverted to the "H" state at the same time as the "H" state is applied to the input terminal T, and is maintained for a time T determined by the internal time constant. AND circuit 5
6 and 57, the clear terminal CL of the J-K flip-flop circuit 45 in the correct answer signal counting section 44 , and the NOR circuit 4 in the answer button section 38 .
1 is applied to the reset terminals of the S-R flip-flop circuit 31 in the signal shaping section 25 and the flip-flop circuit 36 in the control section 33 . As mentioned above, the output j of the correct answer OR circuit 52, which was inverted to the "H" state almost at the same time, is applied to the B input of the AND circuit 56, and the output n of the AND circuit 56 maintains the "H" state for a certain period of time T. A correct answer display lamp 62 is turned on via an inverter 61. In this way, the answer rank display lamp 42 (4), which has been lit since the answer operation, the answer lamp 60 and the correct answer display lamp 62 are lit for a certain period of time T, and the Q output l of the retrigger mono multivibrator 58 falls. At the same time, all the flip-flop circuits are reset and returned to their initial states, and at the same time the lamp 42
(4), 60, and 62 suddenly go out. Next, if you perform the answer operation after presenting the question,
By the same logical operation as described above, tape running is temporarily stopped at the same time as the presentation signal 6 ends, and the Q output e of the S-R flip-flop circuit 36 is applied to the A input of the inverter 59 and the AND circuit 55 in the "H" state. The Q output i of the J-K flip-flop circuit 45 (3) is applied to the B input of the AND circuit 49 (4) in the "H" state, and the response lamp 60
lights up and waits for an answer operation. If the answer button 39(4) corresponding to the correct answer is closed in this state, an "H" state is applied to the input terminal S of the S-R flip-flop circuit 40(4) for the closing time g, At the same time as the rise, the Q output h becomes “H”
The OR circuit 51 and the AND circuit 4 are inverted to the state of
Applied to the A input of 9(4). Therefore, the output k of the AND circuit 55 and the output j of the correct OR circuit 52
are applied to the input terminal T of the retrigger monomultivibrator 58 and the B input of the AND circuit 56, respectively, and the Q of the retrigger monomultivibrator 58
The output l is inverted to the "H" state and applied to the A input of the AND circuit 56. Here, the input terminal RT of the retrigger mono multivibrator 58 has an answer button.
Since the output m of the NOR circuit 43 in 38 is applied in the "L" state only during the time when the answer button 39 (4) is closed, the Q output l of the retrigger mono multivibrator 58 is applied during the closing time " Maintain the state of “H” and release the answer button 39 (4).
After the output m of the NOR circuit 43 is inverted to the "H" state and applied to the input terminal RT, the output m is inverted to the "L" state after a certain period of time T has elapsed. thus
The output n of the AND circuit 56 is the answer button 3 mentioned above.
9(4), the correct answer display lamp 62 is turned on via the inverter 61, and both the answer rank display lamp 42(4) and the answer lamp 60, which are already on, are turned off. In other words, while the question is being presented, regardless of how long the answer button 39 (4) is closed, only the fixed time T during which the question is determined to be correct or incorrect after the instruction signal 6 indicates the end of the question.
If the correct answer display lamp 62 is turned on from the output of the AND circuit 56 via the inverter 61, and the answer button 39 is closed after the instruction signal 6 ends, the output of the AND circuit 59 will be "H" from the moment it is closed. The correct answer display lamp 62 is turned on and remains lit for a certain period of time T even after the answer button 39 is released. Furthermore, re-trigger mono multivibrator 5
At the same time that the output l of No. 8 is reversed from the "H" state to the "L" state, the answer button section 38 is pressed.
The S-R flip-flop circuit 40 is reset via the NOR circuit 41, and the J-K flip-flop circuit 45 in the correct answer signal counting section 44 is reset.
is cleared and the S-R flip-flop circuit 36 in the control unit 33 is reset, the output is inverted from the "L" state to the "H" state, and the transistor 22 is made conductive via the inverter 23 in the magnetic recording/reproducing device 9 . shall be. As a result, the drive motor 10 is released from the stopped state and once again drives the magnetic tape.
1 and move on to the next question. Also, when the answer order for the question is incorrect, the output of one of the AND circuits 50(1) to 50(4) is inverted to the "H" state by the circuit operation similar to the above-mentioned correct answer. The instruction signal 6 is applied to the B input of the AND circuit 57 via the incorrect answer OR circuit 53, and is applied to the Q output l of the retrigger mono multivibrator 58 if the answer operation is presenting a question.
The inverter 63 is activated for a certain period of time T from the end of the question, or until a certain period of time T elapses after the answer button 39 is closed and opened by the answer operation if the question has been presented.
The incorrect answer display lamp 64 is turned on via the button. During this time, the drive motor 10 is in a stopped state, but the lamp 4
2, 60 and 64, that is, when the Q output 1 of the retrigger monomultivibrator 58 falls, all flip-flop circuits are reset,
When the stop state of the drive motor 10 is released, the Q output of the mono multivibrator 65 to which the output of the AND circuit 57 is applied to the input terminal is reversed to the "H" state and is applied to the start circuit 21 for a certain period of time,
The RL relay 16 is operated and the switching circuit 11 is operated accordingly to urge the magnetic tape 1 to rewind. At the same time, the relay contact 16 (1) is opened and the speaker 1 is opened when the magnetic tape 1 is rewinded.
7, the relay contact 16 (2) is switched from the input terminal to the signal shaping section 25 to the input terminal of the rectifier circuit 18, and the signal is regenerated from the magnetic head 13 and is then transmitted to the reproducing amplifier 15. A of the AND circuit 19 in which the correct answer signal 8 and answer signal 7 amplified by the
applied to the input. However, B of AND circuit 19
Since the output of the mono multivibrator 65 is applied to the input, the time required for the tape to pass through the rewind for the correct answer signal 8 that is reproduced immediately after tape rewind is started by the operation of the start circuit 21 is required.
The output of the AND circuit 19 is prohibited. When rewinding progresses and answer signal 7 is played back, its output becomes
The signal is applied to the stop circuit 20 via the AND circuit 19 to stop the operating RL relay 16, and when the rewinding operation is canceled, it also switches to the progressive operation. In this way, the previous question is repeatedly presented and the answer operation is performed again. As detailed above, the present invention automatically moves to the next new question when a correct answer is obtained for a presented question, and automatically rewinds and obtains a correct answer when an incorrect answer is obtained. This is a learning device that allows you to operate the answer even while presenting the question, and if you operate the answer while presenting the question, it will judge whether it is correct or incorrect and display the judgment for a certain period of time after the problem is presented. If the answer operation is after the question is presented, a judgment display is displayed when the switch is closed by the answer operation and until a certain period of time has passed after the switch is opened, so that when the learner has judged the question and performed the answer operation. This system reliably indicates to the learner whether the answer is correct or not, allowing the learner to understand more accurately. In other words, when a learner judges a presented question and performs an answer operation as in the conventional device, the moment the on/off switch is closed, it is judged as correct or incorrect, and the judgment result is only valid for the time the switch is closed. For example, if a learner closes the switch momentarily in a hurry to answer, the correct or incorrect display will be displayed only at the moment of closing, and if the learner is not paying close attention, he or she may miss it. It could also become. In such cases, the learner moves on to the next action without being able to confirm whether the answer is correct or incorrect, which is extremely inconvenient in terms of learning effectiveness. In the present invention, when an answer operation is performed while presenting a question, the judgment is displayed for a certain period of time after the correct/false judgment is made, regardless of the closing time of the open/close switch, and if the answer operation is performed after the question is presented, from the time of closing until a certain period of time has passed after opening. When the judgment display continues, the display lamp corresponding to the answer rank is lit from the time the learner answers the answer, and remains lit until the judgment display is canceled, so that the correctness of the answer to the question is determined according to the answer rank. By displaying the judgment for a certain period of time regardless of the answer operation time, it is possible to clearly determine the order of answers and whether they are correct or incorrect. It also significantly improves learning efficiency.
