The hooks 36 and 37 are provided on the second surface 30b. A strap (not shown) can be hung between the hooks 36 and 37, and the player usually plays the operation such as operating the keyboard KB by hanging the strap on the shoulder. Therefore, when the keyboard portion KB is used on the shoulder, particularly when the scale direction (key arrangement direction) of the keyboard portion KB is the left-right direction, the first surface 30a and the keyboard portion KB face the listener, and the third surface 30c, the fourth surface 30c. The surface 30d faces generally downward and upward, respectively. The neck 31 extends from a side of the main body 30. Various operators including a forward operator 34 and a return operator 35 are arranged on the neck part 31. On the fourth surface 30d of the main body 30, a display unit 33 composed of a liquid crystal or the like is provided.

  The electronic musical instrument 100 is a musical instrument that simulates singing in response to an operation on a performance operator. Here, singing simulation refers to outputting a voice simulating a human voice by singing synthesis. For each key of the keyboard KB, a white key and a black key are arranged in pitch order, and each key is associated with a different pitch. When playing the electronic musical instrument 100, the user presses a desired key on the keyboard KB. The electronic musical instrument 100 detects a key operated by the user and emits a singing sound having a pitch corresponding to the operated key. The order of the syllables of the singing sound to be pronounced is predetermined.

  FIG. 2 is a block diagram of the electronic musical instrument 100. The electronic musical instrument 100 includes a CPU (Central Processing Unit) 10, a timer 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a data storage unit 14, a performance operator 15, and other operations. The control unit includes a control unit 16, a parameter value setting operation unit 17, a display unit 33, a sound source 19, an effect circuit 20, a sound system 21, a communication I / F (Interface), and a bus 23.

  The CPU 10 is a central processing unit that controls the entire electronic musical instrument 100. The timer 11 is a module that measures time. The ROM 12 is a nonvolatile memory that stores a control program, various data, and the like. The RAM 13 is a volatile memory used as a work area of the CPU 10 and various buffers. The display unit 33 is a display module such as a liquid crystal display panel and an organic EL (Electro-Luminescence) panel. The display unit 33 displays the operating state of the electronic musical instrument 100, various setting screens, messages for the user, and the like.

  The performance operator 15 is a module that mainly receives a performance operation for designating a pitch. In the present embodiment, the keyboard KB, the advance operator 34, and the return operator 35 are included in the performance operator 15. As an example, when the performance operation element 15 is a keyboard, the performance operation element 15 includes a note-on / note-off based on the on / off of a sensor corresponding to each key, and the strength (speed, velocity) of key depression. Output performance information. This performance information may be in the form of a MIDI (musical instrument digital interface) message.

  The other operator 16 is, for example, an operation module such as an operation button or an operation knob for performing settings other than the performance, such as settings related to the electronic musical instrument 100. The parameter value setting operator 17 is an operation module, such as an operation button or an operation knob, mainly used for setting a parameter for the attribute of the singing sound. The parameters include, for example, harmony (Harmonics), brightness (Brightness), resonance (Resonance), and gender factor (Gender Factor). Harmony is a parameter for setting the balance of harmonic components included in the voice. Brightness is a parameter for setting the contrast of a voice, and gives a tone change. The resonance is a parameter for setting the tone color and strength of a singing voice or a musical instrument sound. The gender element is a parameter for setting the formant, and changes the thickness and texture of the voice to be feminine or masculine. The external storage device 3 is, for example, an external device connected to the electronic musical instrument 100, and is, for example, a device that stores audio data. The communication I / F 22 is a communication module that communicates with an external device. The bus 23 performs data transfer between each unit in the electronic musical instrument 100.

  The data storage unit 14 stores singing data 14a. The singing data 14a includes lyrics text data, phoneme information database, and the like. The lyrics text data is data describing lyrics. In the lyrics text data, lyrics for each song are described in units of syllables. That is, the lyrics text data has character information obtained by dividing the lyrics into syllables, and this character information is also display information corresponding to the syllable. Here, a syllable is a group of sounds output according to one performance operation. The phoneme information database is a database that stores speech unit data. The speech unit data is data indicating a speech waveform, and includes, for example, spectrum data of a sample sequence of the speech unit as waveform data. The speech unit data includes segment pitch data indicating the pitch of the waveform of the speech unit. The lyrics text data and the speech segment data may be managed by a database, respectively.

  The sound source 19 is a module having a plurality of sound channels. One tone generation channel is assigned to the sound source 19 according to the performance of the user under the control of the CPU 10. When singing a singing sound, the sound source 19 reads vocal segment data corresponding to the performance from the data storage unit 14 and generates singing sound data in the assigned sounding channel. The effect circuit 20 applies the sound effect specified by the parameter value setting operator 17 to the singing sound data generated by the sound source 19. The sound system 21 converts the singing sound data processed by the effect circuit 20 into an analog signal by a digital / analog converter. Then, the sound system 21 amplifies the singing sound converted into the analog signal and outputs the amplified singing sound from a speaker or the like.

  FIG. 3 is a diagram illustrating a main part of the display unit 33. The display unit 33 has a first main area 41, a second main area 42, a first sub area 43, and a second sub area 44 as display areas. The entire display area has a two-row (two-stage) configuration, in which the first main area 41 and the first sub-area 43 are in the first row (upper row), and the second main area 42 and the second sub-area 44 are two rows. It is placed on the eyes (lower). In each of the main areas 41 and 42, a plurality of display frames 45 (45-1, 45-2, 45-3,...) Are arranged in series in the longitudinal direction of the display unit 33. With the display frame 45-1 at the left end of FIG. The main areas 41 and 42 are mainly used for displaying lyrics.

  Next, an operation focusing on singing order and lyrics display will be described. First, the lyrics text data included in the singing data 14a includes at least character information associated with a plurality of syllables corresponding to the selected song. The lyrics text data is data to be sung by the singing unit (sound source 19, effect circuit 20, and sound system 21). The lyrics text data is divided into a plurality of continuous sections in advance, and each of the divided sections is referred to as a “phrase”. A phrase is a unit of a unit and is divided according to a meaning that is easy for a user to recognize, but the definition of a section is not limited to this. When a song is selected, the CPU 10 acquires the song in a state where the song is divided into a plurality of phrases. The phrase includes one or more syllables and character information corresponding to the syllable.

  When the electronic musical instrument 100 is activated, the CPU 10 causes the first main area 41 (FIG. 3) of the display unit 33 to display character information corresponding to the first phrase among a plurality of phrases corresponding to the selected music. At this time, the first character of the first phrase is displayed in the leftmost display frame 45-1, and as many characters as can be displayed in the first main area 41 are displayed. For the second phrase, characters are displayed in the second main area 42 as many as can be displayed. The keyboard KB plays a role as an instruction obtaining unit for obtaining a singing instruction. The CPU 10 causes the singing unit to sing the syllable to be sung next in response to the singing instruction being obtained by operating the keyboard unit KB or the like, and changes the display of the characters displayed in the first main area 41 to the syllable. Proceed according to the progress of. The running direction of the character display is the left direction in FIG. 3, and the characters that cannot be displayed first appear from the rightmost display frame 45 as the singing progresses. The cursor position indicates the syllable to be sung next, and indicates the syllable corresponding to the character displayed in the display frame 45-1 of the first main area 41. The lyrics displayed on the display unit 33 are updated according to the operation of the keyboard KB.

  Note that one character does not always correspond to one syllable. For example, "da" (da) having a cloud point has two characters "ta" (ta) and "" corresponding to one syllable. The lyrics may be in English. For example, when the lyrics are "september", the syllables are "sep", "tem", and "ber". “Sep” is one syllable, but three characters “s”, “e”, and “p” correspond to one syllable. Since the progress of the character display is syllable unit, the character “da” advances two characters by singing. Thus, the lyrics are not limited to Japanese and may be in other languages.

  If all the syllables of the phrase to be displayed in the first main area 41 have been pronounced, the CPU 10 belongs to the phrase next to the phrase to be displayed in the first main area 41. Character information is displayed in the first main area 41, and character information belonging to a phrase next to the phrase to be displayed in the second main area 42 is displayed in the second main area 42. If there is no phrase next to the phrase to be displayed in the second main area 42, no characters are displayed in the second main area 42 (all display frames 45 are blank).

  The advance operator 34 shown in FIG. 1 is an operator for moving up the display in phrase units. An operation of pressing and releasing the advance operation element 34 is an example of a phrase advance operation. The return operator 35 is an operator for moving down the display in phrase units. An operation of pressing and releasing the return operation element 35 is an example of a phrase return operation. The phrase advance operation by the advance operator 34 and the phrase return operation by the return operator 35 correspond to a phrase designating operation (section designating operation) for designating the next phrase to be sounded (sounding target segment).

  When detecting the phrase specifying operation, the CPU 10 determines the next phrase to be pronounced. For example, after detecting the pressing operation of the advance operation element 34 and then detecting the release operation of the advance operation element 34, the CPU 10 determines the next phrase after the current phrase as the phrase to be pronounced. When a release operation of the return operation element 35 is detected after detecting a press operation of the return operation element 35, a phrase immediately before the current phrase is determined as a phrase to be sounded. The pressing operation of the advance operator 34 and the pressing operation of the return operator 35 are the designation start operations of the phrase designation operations. The release operation of the advance operator 34 and the release operation of the return operator 35 are designated end operations of the phrase designation operation.

  In conjunction with the process of determining the phrase to be pronounced, the CPU 10 executes the lyrics display process as follows. This lyrics display processing is executed according to a separate flowchart (not shown). First, upon detecting a phrase advance operation, the CPU 10 executes a phrase display advance process to display the determined sounding target phrase in the first main area 41. For example, the CPU 10 causes the character string previously displayed in the second main area 42 to be displayed in the first main area 41 and further causes the character string of the next phrase to be displayed in the second main area 42. If there is no phrase next to the phrase to be displayed in the second main area 42, no characters are displayed in the second main area 42 (all display frames 45 are blank). On the other hand, when the CPU 10 detects the phrase return operation, the CPU 10 executes the process of moving down the phrase display, thereby displaying the confirmed sound target phrase in the first main area 41. For example, the CPU 10 causes the first main area 41 to display character information belonging to the phrase immediately before the phrase to be displayed in the first main area 41, and displays the character information to be displayed in the second main area 42. Are displayed in the second main area 42.

  By the way, it may take time for the user to recognize the phrase to be pronounced. Until the phrase to be pronounced is determined, the next syllable cannot be pronounced, which may cause discomfort. Therefore, in the present embodiment, in response to detection of a phrase advance operation or a return operation (a section designation operation indicating designation start), the CPU 10 starts to emit a dummy sound (a predetermined singing sound), and The dummy sound is continued until the phrase to be pronounced is determined. The dummy sound is a singing sound such as "ru" by singing synthesis, and the syllable information on which the sound is generated is stored in the ROM 12 in advance regardless of its type. The syllable information that is the basis of the sound of the dummy sound may be attached to the singing data 14a. In the singing data 14a, syllable information for a dummy sound may be attached to each phrase, and a dummy sound corresponding to the current phrase to be pronounced or the next phrase to be pronounced may be generated. Alternatively, a plurality of syllable information that is the basis of the sounding of the dummy sound may be stored, and the dummy sound may be generated based on the singing sound that was sounded immediately before.

  FIG. 4 is a flowchart illustrating an example of the flow of processing when a performance is performed by the electronic musical instrument 100. Here, a description will be given of a process in a case where a user performs selection of a music piece and performance of the selected music piece. Also, for simplicity of description, a case will be described in which only a single tone is output even when a plurality of keys are operated simultaneously. In this case, only the highest pitch among the pitches of keys operated simultaneously may be processed, or only the lowest pitch may be processed. The processing described below is realized, for example, by the CPU 10 executing a program stored in the ROM 12 or the RAM 13. In the processing illustrated in FIG. 4, the CPU 10 plays a role as a data acquisition unit, a detection unit, a sound generation control unit, and a determination unit.

  When the power is turned on, the CPU 10 waits until an operation for selecting a music to be played is received from the user (step S101). If there is no operation for selecting a song after a certain period of time, the CPU 10 may determine that a song set by default has been selected. When receiving the selection of the song, the CPU 10 reads out the lyrics text data of the singing data 14a of the selected song. Then, the CPU 10 sets the cursor position to the first syllable described in the lyrics text data (step S102). Here, the cursor is a virtual index indicating the position of the syllable to be pronounced next. Next, the CPU 10 determines whether or not note-on based on the operation of the keyboard KB has been detected (step S103). When note-on is not detected, the CPU 10 determines whether note-off is detected (step S109). On the other hand, when note-on is detected, that is, when a new key press is detected, the CPU 10 stops outputting the sound if the sound is being output (step S104). The sound in this case may include a dummy sound. Next, the CPU 10 determines whether or not the next phrase to be sounded is in a fixed state (step S105). At the stage where the singing syllables are sequentially advanced in accordance with the acquisition of the singing instruction (note-on), the pronunciation target phrase is in a fixed state. Therefore, in this case, the CPU 10 executes an output sound generation process for generating a singing sound corresponding to the note-on (step S107).

  This output sound generation processing will be described. First, the CPU 10 reads voice unit data (waveform data) of a syllable corresponding to the cursor position, and outputs a sound having a waveform corresponding to the note-on and having a waveform indicated by the read voice unit data. Specifically, the CPU 10 obtains a difference between the pitch indicated by the segment pitch data included in the speech segment data and the pitch corresponding to the operated key, and the waveform data is converted by a frequency corresponding to the difference. The spectrum distribution shown is moved in the frequency axis direction. Thereby, the electronic musical instrument 100 can output a singing sound at a pitch corresponding to the operated key. Next, CPU 10 updates the cursor position (readout position) (step S108), and advances the processing to step S109.

  Here, the determination of the cursor position and the sounding of the singing sound according to the processing of steps S107 and S108 will be described using a specific example. First, updating of the cursor position will be described. FIG. 5 is a diagram showing an example of the lyrics text data. In the example of FIG. 5, the lyrics text data describes lyrics of five syllables c1 to c5. Each character "ha", "ru", "yo", "ko", "i" indicates one Japanese hiragana character, and each character corresponds to one syllable. The CPU 10 updates the cursor position for each syllable. For example, when the cursor is located at the syllable c3, the voice unit data corresponding to “yo” is read from the data storage unit 14 and the singing sound of “yo” is pronounced. When the pronunciation of “yo” is completed, the CPU 10 moves the cursor position to the next syllable c4. As described above, the CPU 10 sequentially moves the cursor position to the next syllable according to the note-on.

  Next, the pronunciation of the singing sound will be described. FIG. 6 is a diagram illustrating an example of types of speech unit data. The CPU 10 extracts speech unit data corresponding to the syllable from the phoneme information database in order to generate a syllable corresponding to the cursor position. There are two types of speech segment data: phoneme chain data and stationary partial data. The phoneme chain data is data indicating a speech unit when the pronunciation changes, such as “silence (#) to consonant”, “consonant to vowel”, “vowel to (the next syllable) consonant or vowel”. . The stationary partial data is data indicating a speech unit when vowel pronunciation continues. For example, when the cursor position is set to “ha (ha)” of the syllable c1, the sound source 19 outputs the voice chain data “# -h” corresponding to “silence → consonant h” and “consonant h → vowel a”. ”, And the stationary partial data“ a ”corresponding to“ vowel a ”. Then, when the performance is started and the key press is detected, the CPU 10 outputs the singing sound based on the voice chain data “# -h”, the voice chain data “ha”, and the steady portion data “a” to the operated key. The pitch is output according to the pitch and the velocity according to the operation. In this way, the cursor position is determined and the singing sound is generated.

  On the other hand, if the result of the determination in step S105 indicates that the next phrase to be pronounced is in an undetermined state, the CPU 10 generates an output sound of a dummy sound at the note-on pitch detected in step S103, and generates the dummy sound. Output. Here, in step S115 described later, the dummy sound has already been output based on the designation start operation. Accordingly, when the pitch of the dummy sound being output is different from the note-on pitch detected in step S103, the CPU 10 sets the dummy sound being output to the note-on pitch detected in step S103. Generate an output sound of the dummy sound so as to correct it. Therefore, after outputting the dummy sound, the performer can correct the pitch of the dummy sound by pressing a key until the next phrase is determined. Thereafter, the process proceeds to step S109.

  If note-off is not detected in step S109 of FIG. 4, the CPU 10 advances the process to step S112. On the other hand, when the note-off is detected, the CPU 10 determines whether or not the next phrase to be sounded is in a fixed state (step S110). At the stage where the singing syllables are sequentially advanced in accordance with the acquisition of the singing instruction (note-on), the pronunciation target phrase is in a fixed state. Therefore, in this case, if a sound is being output, the CPU 10 stops outputting the sound (step S111), and advances the process to step S112. If the result of determination in step S110 is that the next phrase to be pronounced is in an undetermined state, the CPU 10 advances the process to step S112. In step S112, the CPU 10 determines whether or not the designation start operation (the pressing operation of the advance operation element 34 or the return operation element 35) is detected. If the designation start operation is not detected, the CPU 10 determines whether or not the designation end operation (the release operation of the advance operation element 34 or the return operation element 35) has been detected (step S116). Then, when the designation end operation is not detected, the CPU 10 advances the processing to step S121.

  As a result of the determination in step S112, if the designation start operation is detected, the CPU 10 stops outputting the sound if the sound is being output (step S113), and sets the sounding target phrase to an undetermined state (step S113). Step S114). Note that the CPU 10 manages the undetermined state and the determined state of the pronunciation target phrase by, for example, setting a predetermined flag to 0 or 1. Next, the CPU 10 automatically generates a dummy sound and starts outputting the dummy sound (step S115). Thereby, the sounding of the dummy sound is started according to the designation start operation. Thereafter, the process proceeds to step S116.

  If the result of determination in step S116 is that a designation end operation has been detected, the CPU 10 determines the next phrase to be sounded based on the designation start operation detected in step S112 and the designation end operation (step S117). . For example, as described above, after detecting the pressing operation of the operating element 34 in step S112 and detecting the releasing operation of the operating element 34 in step S116, the CPU 10 pronounces the next phrase after the current phrase as described above. Confirm as the target phrase. Next, the CPU 10 updates the read position, that is, updates the cursor position to the first syllable in the determined pronunciation target phrase (step S118). Thus, when a singing instruction is acquired in step S103 after the next phrase to be pronounced is determined, the syllable corresponding to the head of the phrase to be pronounced is sung, and the process can immediately shift to the singing of the determined phrase. The update destination of the cursor position in the determined phrase to be pronounced may be a predetermined position, and not necessarily the head position. Thereafter, the CPU 10 sets the phrase to be sounded to a fixed state (step S119), and stops outputting the dummy sound (step S120). Thereby, the sounding of the dummy sound ends in response to the determination of the sounding target phrase. Thereafter, the process proceeds to step S121.

  In step S121, the CPU 10 executes other processing. For example, if the sound of the dummy sound continues for a certain period of time or longer, the CPU 10 repeats the generation and output of the same dummy sound. Thereby, for example, when the dummy sound "Lou" continues for a long time, the pronunciation of the same syllable as "Rule Lou" can be repeated. Thereafter, the CPU 10 determines whether or not the performance has ended (step S122). If the performance has not ended, the process returns to step S103. On the other hand, when the performance is ended, if a sound is being output, the CPU 10 stops outputting the sound (step S123), and ends the processing illustrated in FIG. Note that the CPU 10 determines whether or not the performance has ended, for example, whether or not the last syllable of the selected song has been pronounced, or whether or not an operation to end the performance has been performed by another operator 16. It can be determined based on

  According to the present embodiment, a dummy sound (predetermined singing sound) different from the singing sound based on the singing instruction is generated in response to the detection of the phrase designation operation. Thus, even if the syllable based on the original singing instruction is stopped every time the phrase is switched, the dummy sound is generated, so that the sense of incongruity at the time of switching the sounding section can be reduced. In particular, the sounding of the dummy sound is started in response to the detection of the designation start operation, and is continued at least until the next sounding target section is determined. Further, since the phrase to be pronounced is determined by the designation ending operation, the dummy sound can be continued to be produced while the user performs the phrase designation operation.

  Further, when an instruction to specify a pitch is acquired during the generation of the dummy sound, the CPU 10 changes the pronunciation pitch of the dummy sound to the specified pitch (step S106). Thereby, the sense of discomfort can be further alleviated.

(Second embodiment)
In the first embodiment, the dummy sound is stopped immediately after the phrase to be pronounced is settled. On the other hand, in the second embodiment of the present invention, the dummy sound that has started sounding is continued until the first note-on after the sounding target phrase is determined. Therefore, step S120 in FIG. 4 may be omitted. Then, by the first note-on after the sounding target phrase has been determined, the dummy sound that has been being output is stopped in step S104. Therefore, it is possible to keep the dummy sound that has started sounding until the note-on after the sounding target phrase is determined.

  Note that the present embodiment is effective in a specification in which, for example, the designation start operation and the designation end operation are completed by one operation. For example, the present invention may be applied to a specification in which the designation start operation and the designation end operation are instructed only by pressing the advance operation element 34 or the return operation element 35, and the release operation has no meaning.

(Third embodiment)
In the first embodiment, when a note-on occurs after the dummy sound is generated, the pitch of the dummy sound is corrected to the note-on pitch by changing the pitch and re-producing the dummy sound. (Step S106). On the other hand, in the third embodiment of the present invention, even if a note-on occurs after the dummy sound is generated, the dummy sound is not regenerated / reproduced.

  FIG. 7 is a part of a flowchart illustrating an example of a processing flow when a performance is performed by the electronic musical instrument 100 according to the third embodiment of the present invention. In this flowchart, the processing before step S103 and the processing after step S109 are the same as those in the flowchart of FIG. Steps S105 and S106 are abolished.

  When note-on is detected in step S103, the CPU 10 determines whether or not a dummy sound is being generated (step S201). If the dummy sound is not being generated, steps S104, S107, and S108 are executed, and the process proceeds to step S109. Accordingly, the sound being generated based on the previous note-on is stopped, and the singing sound based on the current note-on is generated. The suspension of the dummy sound means that the phrase to be pronounced has been determined. On the other hand, when the dummy sound is being generated, the CPU 10 advances the processing to step S109. Therefore, when the dummy sound is being generated, even if there is a note-on, the sound is not generated based on the note-on, and the sound of the dummy sound continues without the pitch being corrected.

  The mode of the phrase designating operation is not limited to the illustrated example, and various variations can be considered. For example, as mentioned in the second embodiment, the designation start operation and the designation end operation are instructed by pressing a designated operation element such as the advance operation element 34 and the return operation element 35 once, and the phrase to be pronounced is designated. May be determined. Further, the phrase to be moved by one set of operations is not limited to the adjacent phrase, and the CPU 10 may jump over a plurality of phrases and determine the phrase to be pronounced. Alternatively, the designation start operation and the designation end operation may be completed by pressing and holding the designated operation element for a certain period of time. At that time, the CPU 10 may determine the phrase to be moved according to the length of time of the long press. The CPU 10 may determine the phrase to be sounded at the destination based on the number of repetitions of the pressing operation and the releasing operation of the designated operation element within a certain time. Alternatively, a configuration may be adopted in which the destination pronunciation target phrase can be specified by a combination of operations of the designated operation element and another operation element. Further, by operating the designated operation element in a predetermined manner, the head phrase of the selected music piece may be determined as the phrase to be pronounced regardless of the current phrase.

  The setting of the cursor position in the determined sounding target phrase and the determined sounding target phrase may be performed as follows. For example, when the phrase specifying operation by the advance operation element 34 is performed in the last phrase of the selected song, the CPU 10 determines the first phrase of the selected song as the phrase to be pronounced, and sets the cursor to the first syllable of the phrase to be pronounced. Good. Further, when a phrase designating operation is performed by the return operation element 35 at the head phrase, the CPU 10 may determine the head phrase of the selected song as the phrase to be sounded, and set the cursor to the head syllable of the phrase to be sounded.

  It should be noted that the singing data 14a of the selected song only needs to be acquired in a state of being divided into a plurality of phrases, and is not limited to being acquired in units of songs, but may be acquired in units of phrases. The manner in which the singing data 14a is stored in the data storage unit 14 is not limited to music units. Further, the acquisition destination of the singing data 14a is not limited to the storage unit, and an external device through the communication I / F 22 may be the acquisition destination. Further, the electronic musical instrument 100 may be edited or created by the user to be acquired by the CPU 10.

  As described above, the present invention has been described in detail based on the preferred embodiments. However, the present invention is not limited to these specific embodiments, and various forms that do not depart from the gist of the present invention are also included in the present invention. included.

  Note that a similar effect may be obtained by reading a storage medium storing a control program represented by software for achieving the present invention into the musical instrument. In this case, the storage medium may be read from the storage medium. The program code itself realizes the novel function of the present invention, and the non-transitory computer-readable recording medium storing the program code constitutes the present invention. Further, the program code may be supplied via a transmission medium or the like, and in that case, the program code itself constitutes the present invention. In addition, as a storage medium in these cases, a floppy disk, a hard disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory card, and the like can be used in addition to the ROM. The “non-transitory computer-readable recording medium” refers to a volatile memory (for example, a volatile memory in a computer system serving as a server or a client when a program is transmitted through a network such as the Internet or a communication line such as a telephone line). Also includes a DRAM (Dynamic Random Access Memory), which holds a program for a certain period of time, such as a DRAM.
