【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block circuit diagram when an embodiment 1 of an information reproducing apparatus according to the present invention is applied to an electronic book player. In the figure, the same reference numerals as those in FIG. 12 denote the same or corresponding portions, and 14 denotes a control signal separation circuit, 1
Reference numeral 5 is a CPU, which is the same as the CPU in FIG.
The CPU is added with a function of receiving a control signal extracted in 4 and performing timer control and operation control of each unit.

Information signals as described above, that is, text data, graphic data, and voice data are recorded on the disc used in this apparatus. Further, the operation of the apparatus is related to a part of this information signal. A control signal for controlling is recorded. FIG. 2 schematically shows signals recorded on this disc. 31 is text data corresponding to one screen, 32 is text data 31 for one screen indicated by an arrow in the figure. Corresponding voice data, text data 31 is LCD
The audio data 32 corresponding to the period displayed in 11 is output from the speaker 13 as reproduced sound. Reference numeral 33 is a control signal, and in this example, it is provided corresponding to a part of the text data 31, as indicated by an arrow in the figure. The contents of the control signal 33 are the contents of the next control processing, the duration of the control, and the contents of the control after the duration has elapsed.

Now, an operation will be described by way of an example when using the software of the problem collection for students as a disc. In this disc, the text data 31 presents a question, and the voice data 32 provides instructions to the user to solve the question. The instruction may be, for example, notification of the remaining time for answering. FIG. 3 shows an operation flowchart. This problem collection disc is mounted on the CD-ROM drive 1, and the user starts using it (S1).
Then, the CPU 15 gives an instruction to the CD-ROM drive 1, reproduces a predetermined portion of the disc, and displays the text data 31 on the LCD 11 by the procedure described above. FIG. 4 is an example of a schematic view of the screen displayed on the LCD 11 at this time. As shown in the figure, the question to be answered by the user is displayed on the LCD 11, and if the questions cannot be displayed on one screen, the entire question can be viewed by scrolling the screen.
At this time, the voice data 32 corresponding to the text data 31 is reproduced by the voice processing unit 12, and the speaker 1
From 3, for example, a voice saying "The answer time for this question is 5 minutes. Please start." Is output (S3).

A control signal 33 is recorded on the text data 31 in association with each other as shown in FIG. 2. The content of the control is, for example, [stop reproduction for 5 minutes after display and voice output. , And then reboot to play the next text and voice data addressed]. Since the control signal has the same format as other data, that is, the same encoding processing and interleaving processing are performed, the data read from the disk is demodulated, error correction processed, and deinterleaved by the data processing unit 2. It is processed and output. The control signal separation circuit 14 selects and extracts only the control signal, and the CPU 15
Is to supply to. The CPU 15 receives the control signal, decodes it, and controls the operation.

When a control signal of the above contents is given,
After the screen of FIG. 4 is displayed and the corresponding audio data is output, the rotation of the disk is stopped for the CD-ROM drive 1, and the disk rotation and the optical pickup are made so as to eliminate or reduce the power supply current consumption. Instructing to turn off the power of the servo circuit portion for controlling tracking and focusing of the optical pickup, feeding of the optical pickup, and the like. Similarly, the power supply to the data processing unit 2 and the voice processing unit 12 is cut off or the oscillation of the master clock signal is stopped (S4). Further, the LCD controller 9 and the LCD 11 are frozen in the display state of the text data of FIG. 4, and if necessary, the display of a predetermined pattern is displayed so that the user can know that the reproduction is paused. This is performed on a part of the display of FIG.

The CPU 15 measures the time designated by the control signal by the internal timer, which is 5 minutes in this example (S
5) During that time, the above-mentioned state is continued. That is, during this period, the user solves the question displayed on the LCD 11 and indicates the answer from the keyboard 7. Even if there is no input from the keyboard 7 within 5 minutes, after 5 minutes have passed (S7)
In order to start the reproduction, the CPU 15 turns on the power sources of the CD-ROM drive 1, the data processing unit 2, etc., searches the address position on the disk designated by the control signal and reproduces it (S9). At this time, the reproduction and display is the next problem for the user to tackle. The audio data informs the user that the answer time for the previous question has expired and reminds him to work on the next newly displayed question. When all the questions have been completed (S8), the operation ends (S1).
0).

Example 2. In the above explanation, the time for the user to answer is set for a preset time, during that period the playback operation is stopped, and the power consumption of unnecessary parts is cut off to suppress the current consumption, and after the set time elapses. I am trying to move on to the next question, but I installed an input key to input a signal to finish the time measurement by the timer device so that the user can answer the question within the set time and move to the next question quickly. When the answer key is input and the end signal input key is operated, the reproduction may be restarted immediately (S6).

Example 3. Next, a third embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a block circuit diagram when the third embodiment is applied to an electronic book player. In the figure, the same reference numerals as those in FIG. 1 indicate the same or corresponding portions, and 16 is a time setting key for the user to externally set the time for temporarily stopping the player's reproduction operation. A control signal is also recorded on a disc reproduced by this apparatus in association with an information signal such as text data. The difference from the first embodiment is the content of the control signal. In the third embodiment, the pause time is set as the unit time number in the control signal corresponding to the specific data requiring the pause during the reproduction. include.

FIG. 6 schematically shows the correspondence relationship of the data recorded on the disc. In the figure, 41, 4
3 and 45 indicate text data and its voice data, 42, 44 and 46 are control signals, and the value indicated by P is a unit of the pause time which is the content of the control signal (hereinafter referred to as "unit"). If 1 unit = 5 seconds, for example, P = 3 is 15 seconds.

Now, the operation when using English conversation practice software as a disc will be described as an example. In this disc, conversation sentences are recorded as text data, and utterances of the conversation are recorded as voice data. FIG. 7 shows an operation flowchart at this time. CD-ROM drive 1
When this disc is mounted on and the user starts using it (S1), the CPU 15 gives an instruction to the CD-ROM drive 1 to reproduce a predetermined portion of the disc, for example, the text + sound data 41 in FIG. (S2) The text data of the conversational sentence is displayed on the LCD 11 by the procedure as described above, and the pronunciation of the conversational sentence is output from the speaker 13 (S3). Is displayed to repeat the pronunciation. The control signal 42 is reproduced following the text + speech data 41, demodulated by the data processing unit 2, subjected to error correction processing, and deinterleaved, and output. The control signal separation circuit 14 selects and extracts only the control data, and the CPU 15
Is to supply to. By receiving the control signal and decoding it, the CPU 15 recognizes that the reproduction should be temporarily stopped at the time when the text + voice data 41 is output.

At this time, the time to be paused is given by the content P of the control signal, and this is a standard time, but this time is not necessarily appropriate depending on the proficiency level of the user. Therefore, the user sets the time setting key 16 in order to adjust the length of the pause, that is, the length of time during which the user speaks according to his or her proficiency level. The time setting key 16 allows the user to select three levels of pause time, such as "beginner (long time)", "intermediate (normal)", "advanced (short time)". The selection information is supplied to the CPU 15 (S21). Corresponding to this selection information, the CPU 15 corresponds to Px = (1 unit time) * 1.2 time for “beginner”, Px = (1 unit time) for “intermediate”, and Px for “advanced”, for example. = (1 unit time) * 0.8 time is set as each pause time. Therefore, when P = 3 of the control signal 42, it is 18 seconds when "Beginner" is selected and 15 when "Intermediate" is selected.
If "Advanced" is selected for seconds, a pause of 12 seconds will be executed (S22).

After stopping the reproduction for a set time (S24), the CPU 15 retrieves and reproduces the text + voice data 43 to be reproduced next, and displays and outputs the voice (S9). After that, the operation of pausing for the time set by the control signal and the time setting key 16 and then reproducing is repeated. Since the disc is not being reproduced during this pause, the disc rotation may be stopped to turn off the power as in the first embodiment. However, if the pause is short, the disc When the rotation is stopped, the power supply current required for restarting is large, and the current consumption may be rather large as a whole. Therefore, the disk rotation is stopped and the power is supplied only when the disk is temporarily stopped for a predetermined time (S23). It may be blocked (S4).

The numerical values used in the above description are examples, and this value can be set freely. Further, the method of setting from the outside is not limited to the above description.

Example 4. Next, a fourth embodiment of the present invention will be described with reference to the drawings. FIG. 8 is a block circuit diagram when the fourth embodiment is applied to an electronic book player, and the same reference numerals as those in FIG. 1 denote the same or corresponding portions. In the figure, reference numeral 17 is a timer for measuring time according to a control signal from the control signal separation circuit 14 and an instruction from the CPU 18, and the CPU 18 causes the CPU 15 of FIG.
The function of controlling the timer 17 in response to the operation from and also processing the output of the timer 17 as one piece of information is added.

Now, a case where the same disk as that described in the first embodiment is used as the disk will be described as an example. FIG. 9 shows an operation flowchart at this time. As described above, when the problem collection disk is mounted on the CD-ROM drive 1 and the user starts using the disk (S1),
The CPU 18 gives an instruction to the CD-ROM drive 1 to reproduce a predetermined portion of the disc (S2), and the LCD 11 displays the text data as shown in FIG. At this time, the voice data corresponding to the text data is played back by the voice processing unit 12, and the speaker 13 outputs the instruction to start the problem by voice (S3). A control signal is recorded with respect to this text data in a relation as shown in FIG. 2, and the reproduced control signal is supplied to the CPU 18 and the timer 17 via the control signal separation circuit 14.

The CPU 18 displays the screen of FIG. 4 on the LCD 11 and outputs the audio data corresponding thereto, and then the CD
With respect to the ROM drive 1, the servo circuit portion for stopping the rotation of the disk and controlling the disk rotation, the tracking and focus of the optical pickup, the feeding of the optical pickup, the data processing section 2, the audio processing section 1
The power supply to 2 is shut off or the oscillation of the master clock signal is stopped (S4). LCD controller 9
For the LCD 11 and the LCD 11, the text data in the display state of FIG. 4 is frozen, and the display of a predetermined pattern is displayed in the display of FIG. Do it in part. On the other hand, the timer 17 starts measuring time after receiving this control signal (S31).

Next, when the user solves the problem displayed on the LCD 11 and inputs an answer from the keyboard 7 (S3
2) In response to this operation, the CPU 18 gives an instruction to the timer 17 and stops the time measurement (S33). Therefore,
A timer 17 measures the time from when a question is given to when the user answers. The measurement result of this timer 17 is CP
It is fed back to U18. Further, in response to the operation of the keyboard 7, the CPU 18 starts the CD to start the reproduction.
-The power supplies of the ROM drive 1, the data processing unit 2, etc. are turned on (S33), and the text data of the next problem is searched for and displayed and voice output (S9).

The time measured by the timer 17 is used as follows, for example. The CPU 18 accumulates the time required to answer each question, and after all the questions are finished (S
8) Display the time taken to answer all the questions (S3)
4). Further, a predetermined time limit is set for each problem, and the problem that exceeds the time limit is displayed on the LCD 11 to notify the user. Further, by displaying the question numbers in ascending order of answering time or in ascending order, it is possible to inform the user of their proficiency level and understanding level.

Example 5. Next, a fifth embodiment of the present invention will be described with reference to the drawings. FIG. 10 is a block circuit diagram when the fifth embodiment is applied to an electronic book player.
