Description

[Detailed description of the invention] The present invention relates to a melody output device.

Many devices for outputting melodies have been used in electronic desktop calculators, clocks, etc., but these prior art devices simply output sounds.
A cuckoo clock is a prior art technology that combines a melody and a character, but the cuckoo clock only outputs the cuckoo as a time signal when the cuckoo comes out of the window, and the appearance of the cuckoo does not change.

Another prior art is disclosed, for example, in Japanese Patent Application Laid-Open No. 53-36321, which is configured to display the pose of a human body on a screen in synchronization with a melody. In such prior art,
Images are displayed using a projector on a single screen board, and audio is output using a recording and playback device, which results in a large configuration and is not fun or interesting to watch. However, it cannot be applied in connection with electronic devices such as calculators and electronic memos, and its range of use is limited.

SUMMARY OF THE INVENTION An object of the present invention is to provide a melody output device that increases interest by displaying characters corresponding to the melody when the melody is output, and that can be made smaller.

The present invention comprises: a display section having a plurality of display positions for individually visually displaying a plurality of characters; a first memory storing an algorithm for displaying the characters and outputting a melody; second memory means for storing the melody and a plurality of characters of the song; audio output means for outputting the melody stored in the second memory as voice; The melody output device is characterized by comprising a control means for reading out a plurality of characters from a second memory and sequentially moving and displaying them to each display position by specifying an address to the character, and for outputting a melody using an audio output means. .

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block circuit diagram of an embodiment of the present invention, showing an example in which the present melody output device is incorporated into an electronic desktop calculator. A control circuit 1 of this electronic desktop calculator is connected via an interface circuit 4 to an operating section 2 having a plurality of keys and a display section 3 for visually displaying a plurality of characters.
Furthermore, a first read-only memory ROM1 stores an algorithm for character display and melody output, and a second read-only memory ROM2 stores melodies of a plurality of songs and a plurality of characters corresponding to predetermined addresses. , random access memory RAM for arithmetic processing,
Audio output means 5 is connected to the control circuit 1.

The melody stored in the second lead-only memory ROM2 is, for example, "Little Dog's Waltz", etc.
As characters, for example, various types of small dogs as shown in FIG. 2 are stored. The display unit 3 may be a 5×7 dot matrix as shown in FIG. 2, a 7×9 or larger matrix, or a segment type display. The audio output means 5 includes a melody output circuit 6, a drive circuit 7, and a speaker 8, from which the melody is output.

FIG. 3 is a flowchart of the present melody output device. When an appropriate key on the operating section 2 is pressed in step n1, the address of the second read-only memory ROM2 is designated in step n2. Assuming that the designated address is "A", it is determined in step n3 whether the contents of address "A" are not stopped. If it is not a stop, it is determined in step n4 whether it is a display code. If it is a stop code at step n3, it is stopped at step n5. If it is a display code at step n4, the character shown in FIG. 2 is displayed on the display section 3 at step n6. If it is not a display code, it is determined in step n7 whether it is a rest code. If it is a rest code, a certain rest time is taken in step n8. If it is not a rest code, a melody is output at step n9. Step n6,
At step n10 following n7 and n9, an address obtained by adding "1" to the aforementioned designated address "A" is designated, and the process returns to step n1.

In this way, the second read-only memory
The address of ROM2 plus 1 is sequentially added and changed, and the display positions D1 to D8 of the display section 3 shown in FIG. 4 are changed.
The characters shown in FIG. 2 are displayed in sequence. For example, characters with different aspects move sequentially, such that Figure 2 1 is displayed at display position D1, Figure 2 2 is displayed at display position D2, and Figure 2 3 is displayed at display position D3. Is displayed. As a result, a ``scene of a small dog spinning round and round looking at its own tail'' is displayed to the tune of the melody of ``Little Dog's Waltz.''

As described above, according to the present invention, a melody is output and characters whose appearance changes in accordance with the melody are displayed on the display section, so that the user can enjoy the music by appealing to the auditory and visual senses.

Particularly, according to the present invention, the display section has a plurality of display positions for individually visually displaying a plurality of characters, and addresses of the second memory are sequentially addressed by the control means. A plurality of characters are sequentially moved to each display position and displayed. Therefore, the characters can be displayed sequentially, for example in a so-called stop motion, and it is very fun and interesting to watch the display while listening to the melody.

Moreover, the configuration of the present invention can be applied to electronic devices such as calculators and electronic memories, and can also be used as a display part, and can easily be made into multiple products. Can be carried to. Such an excellent configuration of the present invention is an excellent effect of the present invention that cannot be achieved by the prior art described above.
