DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now more particularly to the accompanying drawings, one of the preferred embodiments of the picture book related to the present invention is described below.

The picture book shown in FIG. 1 is substantially comprised of the following: a front cover 2, a back-bone 3, and a back-cover 4, which are respectively made by folding a cardboard. In addition, a sound generator 5 is bonded to a predetermined position of the back-cover 4. A plurality of leaves 6, 6, . . . are set to the back-bone 3, while each of these leaves 6, 6, . . . has a cutout portion 8 for allowing insertion of the switch unit 7 of the sound generator 5 and a sound outlet hole 9, respectively.

The switch unit 7 of the sound generator 5 is provided with a total of 16 switches including 12 switches 10.sub.a through 10.sub.l which are disposed in the style of buttons of a push-button telephone and other 4 switches 11.sub.a thrugh 11.sub.d.

As shown in FIG. 2, a micro-cell 12, an integrated circuit 13, and a thinly built speaker unit 14 are internally stored below a cover 5.sub.a of the sound generator 5. Cover 5.sub.a is freely detachable from the sound generator 5 for replacing micro-cell 12.

In an electric circuit 15 shown in FIG. 2, no power switch is provided and the micro-cell constantly feeds DC power to the integrated circuit 13. However, since the integrated circuit 13 is comprised of for example a CMOS-type integrated circuit featuring the least power consumption, the battery life is not a problem.

Switches 10.sub.a through 10.sub.l and 11.sub.a through 11.sub.d are respectively connected to the integrated circuit 13. As soon as one of these switches is pressed ON, the integrated circuit 13 causes speaker unit 14 to generate false piano sounds corresponding to the depressed switch.

FIG. 3 is the illustration in which leaf 6 is placed on the back-bone 4 and a certain page of the picture book remains open.

Switch unit 7 of the sound generator 5 is set to cutout position 8 of leaf 6 which contains picture of a telephone, and thus switch unit 7 looks like buttons of a push-button telephone.

Immitating the pattern of buttons of a push-button telephone, surfaces of switches 10.sub.a through 10.sub.l respectively denote serial numbers 1 through 9, *, 0, and #. On the other hand, surfaces of switches 11.sub.a through 11.sub.d are respectively provided with symbols of a cat, a rat, a trumpet, and a piano.

To deal with switches 10.sub.a through 10.sub.l, integrated circuit 13 selects steps of C, D, E, F, G, A, B, C, D, bB, #C, and #F (in which b means a flat and # means a sharp respectively). Likewise, to deal with switches 11.sub.a through 11.sub.d, integrated circuit 13 selects a variety of tones of that including sound source of cat's mewing, a rat's squeak, trumpet tones, and piano tones, respectively.

Leaf 6 shown in FIG. 3 contains pictures of a lamb, her telephone, and a blackboard, respectively. Her telephone number 7656-777 is shown on her telephone, while another telephone number 864-864 is shown on the blackboard, which denotes the telephone number of a cat having friendly relations with her.

A child first depresses any of switches 11.sub.a through 11.sub.d for selecting tones. Integrated circuit 13 stores tones of sound source in memory.

When the child makes a telephone call to the lamb, the child depresses buttons 7656-777 which is her telephone number. Each of the depressed button generates sound having steps of "B A G A-B B B". These steps are suitable to be be generated vocally by any child. A melody is expressed in terms of the musical scale "si-la-so-la si-si-si" corresponding to a song "Mary had a little lamb". In this way, any child can enjoy operation of telephone as well as nursery rhymes at the same time.

Pretending to be a lamb, when a child makes a telephone call to a cat, the child depress dial buttons 864-864 shown on the blackboard. This generates sound having steps of "C A F-C A F", which in turn results in the playing of the melody of "Pussy Cat, Pussy Cat" at a musical pitch to which any child can easily sing.

FIG. 4 illustrates another leaf 6 which contains cartooned pictures of a lamb, a cat, a rat, a monkey, a trumpet, and a piano, a music score, and numerals/symbols corresponding to switches 10.sub.a through 10.sub.l.

Switch unit 7 of sound generator 5 fits in the cutout portion 8, where switch unit 7 matches the symbol of piano. Accordingly, switch unit 7 shown in this page of the picture book no longer reminds of a telephone, but it impresses to be a musical instrument.

When depressing switches 10.sub.a through 10.sub.l in accordance with the step number shown in this page, the melody of "Happy birthday to you" is generated. If selecting cat's mewing, it makes image as if a cat sings a song. If selecting rat's squeak, it makes image as if a rat sings a song. If selecting trumpet tone, it makes image as if blowing a trumpet. If selecting piano tone, it makes image as if playing on the piano.

In summary, according to the preferred embodiment of the picture book related to the present invention, a wide variety of useful advantages and functions can be offered as described below.

(1) Children could satisfy their potential desire to operate a telephone like adults do. In particular, this picture book can easily be operated by infants of about two years of age.

(2) The picture book can be made available for a kind of musical instrument, while it covers C through C which can easily be generated by normal infants, and yet, it also covers C major, F major and D major which are mostly made available for nursery rhymes. This allows children to sing easy, and yet, since the musical instrument accompanied with this picture book effectively deals with the majority of nursely rhymes, children can promote their own auditory education.

(3) Since the notes of the white keys of piano are set in correspondence with serial numbers 1 through 9 of switching means 10.sub.a through 10.sub.l and the notes of the black keys of piano are also set in correspondence with *, 0, and #, it is easy to understand.

(4) Since the switching unit has the function of a musical instruments together with the function of the dial operation part of a telephone, the content of the picture book significantly expands, thus making it possible for the picture book to present a greater number of stories.

The present invention also provides a wide variety of preferred embodiments. For example, switching means could be disposed on the circumference like a dial telephone. Serial numbers 1, 2, . . . applied to switching means may be replaced by or added with the musical scale do, re, mi, . . . . Symbol * may also be replaced by b.

Another preferred embodiment allows a plurality of LEDs to light up themselves when sound is generated.

As is clear from the foregoing description, the picture book related to the present invention mounts a switch unit on part of the book, where the switch unit is arranged in the style of an immitated telephone dial and is provided with a plurality of switching means. The picture book also provides a sound generator having a unit for generating false musical instrumental sounds corresponding to activated switching means mentioned above. The picture book related to the invention is provided with at least one of two kinds of leaves, the one containing a picture to allow the switch unit to share part of the telephone and the other one containing a picture which makes up part of musical instrument.

In other words, the picture book related to the present invention integrally mounts a sound generator, while a switch unit of the sound generator has a plurality of switching means which are disposed in the style of imitating the dial part of telephone.

Depending on the pictures of the leaves of the book, the switch unit becomes part of the telephone unit.

Therefore, an infant can play with the telephone unit and suffice a potential desire to keep in touch with a telephone.

On the other hand, depending on the combination of the telephone dial with symbolic pattern of a leaf of the picture book, the switch unit reminds of a music instrument. When an infant operates switching means, false musical instrument sound is generated.

This allows the infant to enjoy herself with the toy musical instrument and it becomes useful for auditory education.

Furthermore, since the switch unit can work as a telephone or as a musical instrument, the content of the picture book itself can be expanded with a wide variety of subjects.

This invention may variably be modified or changed for embodiment in many ways without departing from the spirit and scope of the invention. Those preferred embodiments described above are thus illustrative and not limitative, while the scope of the invention indicated by and all variations within the meaning of the following claims are thus intended to be included therein.
