High educational effect can be expected. In addition, the learner is a picture book and the multimedia information associated with the picture book is packaged and replaceable, so if the contents of the package are diversified, it can be used for drawing, writing, and language practice.

Hereinafter, referring to the accompanying drawings, a conventional multi-purpose learner will be described.

1 is a schematic diagram of a conventional learner system.

2 is an external view of a conventional picture book package.

As shown in FIG. 1, the conventional learner 10 includes a learner main body 11 formed of two upper and lower cases that are foldable and interconnected, and a picture book package 12 that is detachable at a predetermined position of the upper case. Include.

The upper case of the learner main body 11 includes a control means for controlling the overall operation of the learner therein, a voice output for outputting a sound signal to the separate output device unit 20 corresponding to the picture of the picture book A terminal and an image output terminal for outputting an image signal are provided, and the lower case also has an electronic pen 14 for allowing a user to select a predetermined portion of a picture in a picture book and a touch panel for drawing. It includes.

That is, as the electronic pen 14 moves on the touch panel 13 in a specific operation mode by the control means, the movement of the electronic pen 14 appears on the monitor screen of the output device unit 20 as the movement of a cursor. The user may select a separate menu provided in the picture book, that is, a pencil function, an eraser function, a color, and the like, and press the electronic pen 14 to perform drawing.

As illustrated in FIG. 2, the picture book package 12 includes a case of a predetermined size and a picture book having a plurality of surfaces on which a predetermined picture is drawn on the outside of the case, and inside each case of the picture book. It is provided with an information storage unit containing the multimedia information related to the picture drawn in the main body connecting portion 43 for attaching and detaching at a predetermined position of the learner main body (11).

The general operation of the conventional learner configured as described above is as follows.

First, the user selects and inserts a picture book package 12 to be learned at a predetermined position of the learner main body 11. Thereafter, when power is applied to the learner main body 11, the same screen as the picture on the cover surface of the picture book is displayed on the output device unit 20, and the voice corresponding to the screen is output to the user.

Each side of the picture book is cut off by a predetermined length in proportion to the number of planes of the picture book 40 so that the control means of the learner main body 11 shows the unfolded surface. This is because when the picture book package 12 is inserted into the learner main body 11, a predetermined number of surface identification detectors 15 are installed in the corresponding part of the learner main body 11 in which the upper right part of the picture book is located. Turning the bookshelf 41 allows you to know which side is open.

Therefore, when the user unfolds the bookshelf 41 of the picture book, the control means of the learner main body 11 reads the same multimedia information as the picture drawn on the unfolded surface from the information storage unit in the picture book package 12, and then after predetermined processing television. It is displayed on the screen of the output device unit 20 such as (Television). The multimedia information is composed of sound and image data, and initially, the same screen as the picture drawn on the unfolded surface is displayed on the output device unit 20.

Thereafter, when the user presses the specific object of the picture drawn on the unfolded surface with the electronic pen 14, the moving picture and the voice related to the specific object are displayed on the screen of the output device unit. For example, if the specific object is the sun, the screen of the sun rising from the east and the west is displayed as a moving image, and if the specific object is the cloud, the screen is displayed as a moving image of the cloud in the sky.

Therefore, when the user turns over the bookshelf of the picture book, the screen of the output device unit 20 is switched to a new screen corresponding to the contents of the bookshelf.

Since the information storage unit of the picture book package 12 has the same picture contained in the picture book and voice information and video information corresponding to the learning content, the user can access new learning content by replacing only the picture book package 12 when necessary. Will be.

In order to further enhance the user's fun and interest in the multi-purpose learner operating as described above, the information storage unit installed in the conventional picture book package 12 provides song information related to the picture contents of the picture book, in particular, multimedia information about nursery rhymes. By adding, I want to construct a nursery rhyme. The nursery rhyme used here means a simple karaoke, especially composed of nursery rhymes.

In order to configure the nursery, a means for receiving a user's voice and mixing the multimedia information to the output device unit 20 should be added.

However, the conventional picture book package 12, which can be exchanged in the form of a package in the multi-purpose learner, has only a mask ROM mounted therein as the information storage 42 therein, and thus does not require a predetermined electronic circuit part. Could not have.

Therefore, in order to construct a nursery chamber, a circuit capable of accepting a microphone input to a learner, and mixing accompaniment data among the user's voice signal input from the microphone and the multimedia information read from the information storage unit 42 are mixed. It is necessary to have a circuit built in.

However, the conventional multi-purpose learner has a problem in that a separate signal mixing means having a mixing function for mixing user voice signals and accompaniment data is added to the learner body in order to implement the nursery in the learner body.

In addition, when the nursery rhyme function is embedded in the main body of the learner, it is difficult to implement a specific nursery rhyme suitable for the content of the picture book for a particular picture book package.

Accordingly, an object of the present invention is to solve the above problems, the built-in shaking function in a specific picture book package by configuring the multi-purpose learner having a shaking function to select a picture book package having a shaking function according to the user's needs In providing.

It is another object of the present invention to turn on the microphone function when the accompaniment starts and to turn off the microphone input processing function when the accompaniment ends, even when the microphone is normally turned on, the microphone input processing function does not operate when there is no accompaniment. Accordingly, the present invention provides a multi-purpose learner which eliminates a howling phenomenon caused by re-input of a sound signal of the learner main body into a microphone.
