FIG. 6 shows a control flowchart executed by the control circuit 210 when executing the karaoke function. Broadly speaking, an initialization step (S100) for initializing a circuit related to the voice input processing, a sub-screen display step (S200) for displaying a sub-screen corresponding to a picture on a text page when the picture is designated, Accompaniment start stage (S300) for starting the accompaniment program after confirming the instruction of the microphone mark (voice input mark) in the sub-screen, and ending the accompaniment program when the microphone mark in the sub-screen is re-instructed Step (S400) is performed. The microphone mark is placed on the text page where karaoke is prepared, so that it is easy to recognize that karaoke is possible.

First, when the power of the learning device system is turned on, all the circuits related to the voice input processing are initialized (S1).
00). When the initialization is completed, it is monitored whether any page in the text of the text package 100 is opened and a picture in the page is indicated by the operation of the electronic pen (S2).
10). That is, it is monitored whether any one of the pictures of the elephant, the rabbit, and the sun on the predetermined page in the text displayed on the screen as shown in FIG. If there is an instruction (click), a subprogram corresponding to the picture is activated, and an image (moving image) and sound data, which are sub-screen data corresponding to the selected picture, are read from the information storage unit 104 and processed. ,
The video signal and the audio signal are output to the output device 300 (S220). In the subprogram at this time, for example, when a picture of an elephant is selected, several titles of elephant-related nursery rhymes are displayed together with the moving image and sound, and one of them can be selected. it can.

Thereafter, it is monitored whether the microphone mark (or the microphone button can be provided on the learning device main body 200 or the text package 100) in the displayed sub-screen is operated by the electronic pen operation (S310). . As a result, if the microphone mark is instructed, the accompaniment program for the picture being displayed is started (S320), and the voice input function is turned on (the microphone on / off unit 120 is turned on) to enable the voice input by the microphone 35. (S330). Thereby, the accompaniment data read from the information storage unit 104 and reproduced by the acoustic drive circuit 220 and the sound input by the microphone 35 are mixed by the signal mixing circuit 105 and output from the speaker 320 of the output device 300. Is done.

After the start of karaoke, it is monitored whether or not the microphone mark in the displayed sub-screen is re-instructed (S410), and if there is a re-instruction, the accompaniment program is stopped (S420). If there is no re-instruction, the reproduction is continued until the accompaniment is completed (S430).

When the accompaniment program ends, the voice input function is turned off (the microphone on / off unit 120 is turned off) (S440) to prevent howling.

When the end of the subprogram is confirmed, the whole page is displayed. After confirming whether the page is turned, it is monitored whether a picture in the page is selected (S450). If the page is not turned and there is no instruction for a different picture, the instruction of the microphone mark on the sub screen is monitored by executing the same subprogram as it is (S3).
10). On the other hand, if the page is turned or an instruction for a different picture on the same page is given, the corresponding subprogram is started from step S220.

If the microphone mark is not instructed in step S310, the flow jumps to step S440 to keep the voice input function off to prevent howling.

As described above, the multi-purpose learning device of the present embodiment has the voice input means, and outputs the signal by mixing the voice signal input by the voice input means with the audio signal reproduced by the learning device main body. With a mixing circuit, if you store accompaniment data in the information storage unit in the text package,
Karaoke learning can be done easily.

In addition to the above example, a signal synthesizing circuit for synthesizing an audio signal and an audio signal can be provided in the learning device main body 200. That is, as shown in FIG. 7, a control circuit 210 that reads data from an information storage unit 104 built in a text package 100 and controls the entire system, an audio drive circuit 220 for audio reproduction, and a video drive for video reproduction. The learning unit 200 includes a circuit 230 and a signal mixing circuit 105 that mixes an audio signal from the microphone 35 and an audio signal from the audio driving circuit 220. In this case, the microphone 35 as the voice input means
Is connected to an audio input terminal provided at a predetermined position of the learning device main body 200.

[0032]

According to the present invention, by adding a karaoke function to the learning device, the added value is increased, the range of selection is greatly expanded, and more diverse needs can be met. Also, howling is prevented by the automatic on / off of the voice input means, and the usability is good.
