ABSTRACT:
BACKGROUND OF THE INVENTION
1. [Field of the Invention]
The present invention relates to electronic musical instruments with help functions, particularly to electronic musical instruments each including a sound source for producing musical sounds in an electronic manner, and a display for giving explanations of various functions in the instrument.
2. [Description of the Related Art]
Various electronic musical instruments with help functions have been proposed heretofore. For example, in Japanese Patent Application Laid-open No. 204301/1993 “Explanation Device in Electronic Musical Instrument”, an explanation of the function assigned to an operation member is given with a voice or a picture when the operation member is operated in a help mode after a help switch is made on.
In Japanese Patent Application Laid-open No. 253779/1995 “Electronic Musical Instrument”, given is an explanation of the function assigned to an assignable switch. When a help operation member is operated after the switch is operated, an explanation related to the switch is given on a display.
Although the above Japanese Patent Application Laid-open Nos. 204301/1993 and 253779/1995 are different in details, they are basically the same in the point that an explanation of the function related to an individual switch is given after a help switch is made on.
In short, any conventional electronic musical instrument with a help function is not designed to explain its functions systematically. The most ordinary method for grasping the functions of the electronic musical instrument, i.e., the method of searching from a rough category to a minute category in order can not be taken therefore. For this reason, a textbook such as an owner's manual can not be disused though the electronic musical instrument has the help function.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an electronic musical instrument with a help function capable of giving explanations of its functions in an appropriate order.
According to the present invention, an electronic musical instrument has play modes and a help function in which a help picture is displayed in accordance with each of the play modes. The play modes include a normal play mode. The electronic musical instrument comprises help function instruction means for instructing to start the help function; help function start means for starting the help function when it is instructed with the help function instruction means; and display control means for displaying a picture for selecting one of the play modes when the help function is started in the normal play mode, and a help picture corresponding to one of the play modes but the normal play mode when the help function is started in the corresponding play mode.
According to another aspect of the present invention, an electronic musical instrument comprises storage means for storing a sequence of operations performed after the help function is started till a predetermined help picture is displayed; reproduction means for reproducing a sequence of operations stored in the storage means; and display control means for displaying a predetermined help picture in accordance with a sequence of operations reproduced by the reproduction means.
According to still another aspect of the present invention, an electronic musical instrument comprises storage means for storing information for introducing a predetermined help picture of a predetermined mode of the help function; reproduction means for reading out information on the predetermined help picture of the predetermined mode from the storage means; and display control means for displaying the predetermined help picture based on information read out through the reproduction means.
