Description

[Detailed description of the invention]

The present invention relates to a musical score printing means suitable for use in composition, performance practice, etc., which generates an autorhythm sound before the start of keyboard play, and starts storing performance data from the start of keyboard play. This makes it possible to obtain high-quality sheet music prints. Conventionally proposed musical score printing devices are not provided with an autorhythm device, so it is not possible to start playing the keyboard in accordance with the autorhythm, and the playing tempo tends to fluctuate. Furthermore, if the memorization operation is started before the keyboard performance begins, there is a problem in that a row of rests is printed at the beginning of the 11th note. An object of the present invention is to provide a novel musical score printing device that can obtain high-quality musical score prints by starting keyboard performance in accordance with the O) +7 rhythm. The musical score printing device according to the present invention starts generating rhythm sounds based on the operation of the play switch.
In addition to providing a rhythm device, a storage means is provided in which writing of musical score data corresponding to the content of the performance is started from the start of the keyboard performance, and music and f% printing is performed based on the musical score data read from the storage means. The following is a detailed description of the embodiments shown in the appendix.

B functions as a reprint command switch REPR when pressed at the same time, and by doing so, the space for arranging the switches can be reduced since a dedicated switch for reprint commands is not required. However, in the following circuit description, for convenience, it is assumed that there is an independent reprint command switch. FIG. 2 shows a horizontally long printing paper 16, the leading end 16a of which is sharpened so that it can be easily loaded into a printer 17. On the print paper 16, - for example, 4 measures are written in 1
Musical scores are printed sequentially as bar blocks, and "5" is placed near the first measure of each of the second and subsequent measure blocks B*, Bl, etc., excluding the first measure block B1.
, "9", etc. are printed. By assigning measure numbers in this way, it is possible to divide the print paper 16 into measure blocks at the print end edge and rearrange them vertically on the mount 18-F as shown in FIG. You can see the arrangement order at a glance, which is very convenient. FIGS. 4(a) and (1)) show examples of prints by the above-mentioned musical score printing device, and print 1
I will give an overview of the work I111. Note that the print operation is performed using the memory play print switch MPLP.

FIG. 4(b) is an example of a print when length data correction processing is performed. As shown in FIG. 4(b), after the first bar line SL and the first bar staff are printed, a clef such as a treble clef and a time signature such as a foil are printed. In addition,
If the song requires a key symbol, use the key setting screen mentioned above,
Depending on the key setting by either SH8 or FLS, a key symbol is printed at the position indicated by the broken line SF, and printing starts from the first bar line SL onwards. Next, the notes of the first measure (including rests) are printed on the previously printed staff of the first measure according to the performance content, and accidental symbols such as ties, naturals, sharps, flats, etc. are printed as necessary. is also printed. Then, at the end of the first measure, the bar line and staff of the second measure are printed, and then the notes of the second measure are printed according to the content of the performance. Similar printing operations are performed for the third and fourth measures as well. After this, at the end of the fourth measure, the bar line at the end of the fourth measure is printed, but in this case, the staff line at the next fifth measure is not printed. Next, after taking up space with the paper feed, if it is not a C major chord, the key mark of the 5th measure is printed, the bar line and staff at the beginning of the 5th measure are printed, and the clef is also printed. . Then, the notes of the fifth measure are printed. Thereafter, the same printing operation as in the case of the second measure described above is performed for the sixth measure to the eighth measure. Assuming that the performance ends at the end of the 8th measure, a stop aEL is printed at the end position of the 8th measure. In addition, Fig. 4-t')i, [JAZZ ROC! K
Rhythm names such as J and chord names such as "C" and "G?-1" are printed, but in the device of the embodiment described later, the configuration related to the printing function of "C" can be omitted. Next, the circuit operation of the above musical score printing device will be explained with reference to FIGS. 5 to 7. The keyboard +1-ill Kimoto detects the keyboard and the keys pressed on this keyboard, The key pressing data K'Cj is supplied to the musical tone forming circuit 22 and converted into a musical tone signal corresponding to the pressed key. The musical tone signal from the musical tone forming circuit 22 is supplied to the speaker 26 via the output amplifier 24, and is acoustically converted. Note that a print mode signal PM is supplied to the musical tone forming circuit n via the inverter 22a. Therefore, musical tone formation is prohibited during the printing operation.Key press data KC from the keyboard circuit 20 is supplied to the selector column as input A, and is also supplied to the OR gate (source) and The gate 30 also supplies key press data KO to an event detection circuit 32 so that when any key is pressed on the keyboard, a key-on signal KON is generated.The event detection circuit 32 detects a key press based on the key press data KC. It generates an output signal synchronized with the timing of key release and key release.
These output signals are supplied to the note length data forming circuit via an OR gate. The note length data forming circuit 36 counts the clock signal φ to form note length data corresponding to the time interval between key press and key release timings, and supplies the formed note length data to the data rounding circuit 37. be done. The data rounding circuit 37 converts the received note length data into, for example, 4
Even if it is approximate to the diacritic note length, it is sent out as indicating the quarter note length, and the rounded note length data is supplied as input B to the selector string. When the memory play/print switch MPLP is turned on to start playing the keyboard, the ON signal 11# of the switch MPLP is ORed on the control signal generation circuit side shown in FIG.
It is sent out through gate 39 as operation command signal RUN. This 111 operation command signal RUN enables the autorhythm device 4o in FIG. 5 to perform the i+II operation.
The rhythm device 40 automatically generates a rhythm sound signal based on the tempo clock signal from the variable tempo oscillator 42. This rhythm sound signal is sent to the speaker 2 via the output amplifier 24.
6 and is acoustically converted. Therefore, the player can start playing the keyboard in time with the O) II rhythm tone. In the control signal generation circuit 38 of FIG.
The rising differential circuit 43 generates a clear signal OLR based on the ON operation of PLP. This clear signal D II R
is for clearing memories, counters, registers, etc., but for the sake of simplicity, illustration of the signal supply destination is omitted. Next, when the player starts playing the keyboard while keeping the tempo with the autorhythm sound, the 6-input operation of the musical score data corresponding to the content of the performance starts σ1J. That is, when the first key press operation is performed, the output of the OR game () 34 in FIG. Select key press data Kc (pitch data corresponding to the first key press) from the circuit adder,
The data is supplied to a temporary memory 44 having a storage capacity for one bar. On the other hand, in the control signal generation circuit A of FIG. 7, the first key-on detection circuit 46 generates a toe key-on detection signal in response to the key-on signal KON from the OR gate of FIG. This first key-on detection signal is passed through an AND gate (50) which is rendered conductive by the ON signal of the switches MPI and P from the OR gate 48, and further via an OR gate 51 as a memory mode signal MM to the AND gate shown in FIG. 5
2. At this time, the flip-flop output Q=-Oz makes the AND gate 52 conductive via the inverter 56. Therefore, the AND gate 52 outputs the memory mode signal MM.
A write command signal W is supplied to the temporary memory 44 in response to this. Further, the output signal %11 of the OR gate generated in response to the first key depression is supplied as input A to the selector 60 via the OR gate 58. At this time, the selector mark selects input A since the R-87 lip-flop 54 is in the reset state, and the output signal of the OR gate 58 is supplied to the address counter 62 as the clock input CK via the selector 60. . Therefore, the first pitch data is written into the temporary memory 44 in response to the first address signal from the counter 62. Next, when the note length data forming circuit 36 finishes forming the first note length data in synchronization with the first key release timing, this note length data is supplied as input B to the selector path via the data rounding circuit 37. Meanwhile, an end signal E ND is generated. This end signal END. is supplied to the selector path as a signal SB for selecting input B, and is also supplied to the counter 62 via the OR gate 58 and the selector 60. Therefore, the first note length data is written into the temporary memory 44 in the same manner as the first pitch data described above. Thereafter, pitch data and note length data corresponding to each of the second and subsequent key presses are written into the temporary memory 44 in the same manner as in the first example. Note that for rests, note length data corresponding to a note length in which all bits other than mark pits are pitch 10 is written in the temporary memory 44. At the end of the first measure, the measure counter 64 generates a carry-out signal CO. This bar counter is the 7th
The counting of the clock signal φ is started in response to the normal start signal MST which is obtained by differentiating the output signal of the AND gate 50 shown in the figure by the differentiating circuit 66.
The division ratio is set according to the time signature setting signal TS from the station. That is, when a specific rhythm is selected by the autorhythm device 40, a time signature setting signal TS corresponding to the time signature of the selected rhythm is supplied to the measure counter 64, so that the measure counter 64 is set at a period corresponding to the set time signature. A carry-out signal CO is generated at the end of each bar. The carry signal CO from the counter 64 is supplied to a bar data forming circuit 68, and in response, the bar data forming circuit 68 forms bar data indicating the end of a bar and supplies it as an input C to a selector. Then, when the measure data forming circuit 68 finishes the measure data forming process, it generates an end signal E N D,. This end signal EN D is supplied to the selector path as a signal BC for selecting the input C, and is also supplied to the counter 6 via the OR gate 58 and the selector 60, so that the temporary memory 44 stores the measure Data is written. Note that the counter 64 receives the carry signal CO. If a key is pressed on the keyboard at the time when I7 occurs, the OR gate (capital) generates the key-on signal KON and A
Since the ND gate 70 is conductive, the AND gate 7
0 is a tie signal t4'r in response to the carry field signal CO.
Supplied as input A to the r1 selector key. Further, the carry-out signal CO at this time is supplied to the OR gate 'O34, and acts as a kind of key release timing signal. Therefore, 74 pieces of the last γY height data and note length data of the first measure are sequentially stored in the temporary memory 44.
After that, measure data is written. To enable such operations, the measure data forming circuit 6
No. 8 starts the data forming operation with a slight delay from the time when the carry field No. 1 CO is generated. The pitch data written as above includes the tie signal TI, so when printing, the last note of the first measure and the first note of the second measure are connected with a tie. Become. On the other hand, the carry signal from the counter 61 is
The flip-flop 54 is set via the R gate 72 and the delay circuit 7.1. Therefore, the output Q == % of the flip 70 tsubu key I is the memory mode signal MM
temporary memory 44 through AIJD gate 76 which is conductive at
is supplied as a read command signal RE. Okay, the output Q-%11 of the flip-flop 54 is the input B to the selector 60.
The selector 60 selects the clock signal φ and supplies it to the counter 62. The counter 62 is connected to the delay circuit 7 by the OR gate 78.
When an output signal corresponding to the output signal DL of 4 is generated, it is reset. After this reset, the clock signal φ from the selector 60 is counted and the temporary memory 44 is
A read address signal is supplied to. For this reason, musical score data for one bar is read out from the temporary memory 44 and supplied as the main memo. In addition, the flip-flop output Q-%II is supplied as a write command signal W to the main memory +1)1 via an AND gate 82 turned on by the memory mode signal MM.
AND gate 84 is made conductive. Therefore, the AND gate 84 transfers the clock signal φ to the write address counter 86.
The counter 86 receives the clock signal φ
is counted and a write address signal is supplied as input A to the selector lever. At this time, the selector 88 selects the flip 70
Since the input A is selected in response to the output Q=%l# of the knob 54, the write AT1/S signal from the counter 86 is supplied to the main memory via the selector 88. Therefore, the musical score data for one measure read from the temporary memory 44 is sequentially written to the main memory 80.
1 to the main memory 80 is performed at high speed. In such data transfer, the data correction circuit included in the main memo 113Q enables musically appropriate printing (see Figure 4) in response to the operation command signal RLJN from the OR game 80a. A note length data correction process is performed, and the data subjected to this process is written into the storage section of the main memo 180. In the data transfer as described above, the first measure data is read out from the temporary memory 44 as the last transfer data. When this measure data is supplied to the measure/end detection circuit 90, the circuit 90 generates the first measure pulse signal MP. Since this measure pulse signal MP resets each flip-flop, the selector 60 enters a state in which input A is selected, and the temporary memory 44 enters a write mode. In the circuit shown in FIG. 7, the first bar pulse detection circuit 92 generates a detection signal in response to the first bar pulse signal MP. This detection signal is passed through an AND gate 94 made conductive by the ON signal of the switch MPLP, and further OR
The rising edge is supplied to a differential circuit 98 via a gate 96 and converted into a differential pulse signal. This differential pulse signal is sent out as the print start signal PST, while the OR
An R-8 flip-flop 102 is set through gate 100. Therefore, the flip-flop 102 generates a print mode signal PM consisting of an output Q='l'. On the other hand, the ANT) gate 82 in FIG.
11 power signal is ANDed via inverter 304) 1
06 is made conductive. This tanu is pretending to be Figure 7. Print mode signal PM from knob flop 102 is AN
When supplied to D gate 106, AND gate 106 provides a read command signal RE to main memory 80. Therefore, the selector 88 enters a state in which the input B is selected by the output Q-%Q# of the flip-flop 54. Note that the bar pulse signal MP is OR
Counter 62 is reset via gate 78. After transferring one measure of musical score data as described above, a musical score printing operation is started by sequentially reading out the musical score data from the second memory 80, which will be described later. In the circuit shown in FIG. 5, as the keyboard performance progresses, musical score data for each measure from the second measure onward is stored in the temporary memory 44 in the same way as described above. Each time musical score data is written, the written data is transferred to the main memory 80 at high speed. After repeating this operation for several measures, for example, assuming that the keyboard performance is to be stopped at the end of the eighth measure as shown in FIG. 4, the performer turns off the memory play print switch MPLP. Then, in the circuit of Fig. 7, A
Since the output signal of the ND gate 50 becomes O1, the falling differentiation circuit 108 which receives this as an input outputs the stop signal STP.
occurs. This stop signal STP resets the detection circuits 46 and 92 while being supplied to the stop data forming circuit 110 of FIG. In addition, the stop signal STP is converted into a pulse signal of a predetermined width by a one-shot circuit 09 provided to enable transfer of score data of the last measure, and this pulse signal is passed through an OR gate 51 as a memory mode signal MM. Sent out. Note that the standing differential circuit 111 which inputs the state signal of the switch MPLP is provided together with the one-shot circuit 113 which receives the output of this circuit to enable correction processing of the note length data of the last measure. A pulse signal of a predetermined width from the shot circuit 113 is sent out via an OR gate 39 as an operation command signal RUN. The final data forming circuit 110 forms the final data based on the stop signal STP, and supplies the final data to the selector field as an input.
occurs. This end signal END. is supplied to the selector 4 as a signal SD for selecting the input, and is also supplied to the counter 62 via the OR gate 58 and the selector 60. Therefore, the final IF data is written into the temporary memory 14. The stop signal STP is 1 and causes the flip 70 block 54 to be set via the OR gate 72 and the delay circuit 74. Therefore, the musical score data of the final measure is transferred at high speed from the temporary memory 44 to the main memory 8o in the same way as at the end of the measure described above. In this case, when the end IF data finally read out from the temporary memory 4 is supplied to the bar/end IF detection circuit 90, the circuit generates the bar pulse signal MP. This bar pulse signal MP resets the flip-flop register and is sent to the counter 6 via the OR gate 78.
2 is reset. When the flip-flop is reset, the main memory goes into the read mode as described above, the AND gate 84 becomes non-conductive, and the selector 8
8 is in a state where input B is selected. Note that when the memory play/print switch MPLP is turned off, the operation command signal RUN becomes 1 after the duration of the output pulse of the one-shot circuit 113 has elapsed from the time when the memory play/print switch MPLP is turned off.
0#, and the output of the rhythm sound by the autorhythm device 40 in FIG. 5 is stopped. Next, the musical score printing operation will be explained. As previously mentioned,
The measure/end detection circuit generates the first measure pulse signal MP when the music score data of the first measure has been transferred to the main memory 80, and in response to this, the control signal generation circuit shown in FIG. A print start signal PST and a print mode signal PM are generated. This print start signal P
ST and PRINTER: - The actual musical score printing operation starts with the generation of the mode signal PM, but since the key symbol of the first measure is printed at the time of setting the key, the data generation circuit 112 including the key setting means will be explained first. The data generating circuit 1 and 2 are for generating print/paper feed data for key signatures, and have a configuration as shown in FIG. 8, for example. In the circuit shown in FIG. 8, the key setting is normally performed by turning the key setting switch SH8 or FLS before the performance starts or when printing is interrupted. That is, since the inverter 116 inputting the print mode signal PM makes the AND gates 18 and 120 conductive in the non-print mode, various sharp and flat tone settings as shown in FIG. HS father is made possible using FLS. Here, to set the key of the Nyab type, when the R-S flip-flop +22 is reset for the C major key, it is sufficient to press the sharp keynote setting switch SH8 the number of times corresponding to the required number of Nyab. For example, switch S
When H8 is pressed once, the flip-flop 122 is set, and the AND gate 11 with its output Q;111 as an input is set.
8 is switch 81 (S on signal is sent to sharp counter 1
24. Therefore, the counter 124 increments by one count and supplies the counted data to the OR circuit 126, while also supplying it as a sharp number designation signal to the data conversion circuit 128 including a ROM (read only memory) and the like. At this time, the data conversion circuit 128 includes the switch 8H.
The ON signal of 8 is supplied as a sharp print command signal. The sharp number designation signal and the sharp print command signal supplied to the data conversion circuit 128 are converted into print/paper feed data for the sharp sign and sent out. On the other hand, in order to set the flat key tone, when the R-S flip-flop 132 is reset and the key tone is set, the flat key tone setting switch FLS may be pressed the number of times corresponding to the required number of flat keys. For example, switch FLS
Pressing once sets the flip-flop 132,
The AND gate 20 whose output is Q=%]I supplies the ON signal of the switch FL8 to the flat counter 134. Therefore, the counter 134 increments by one count and supplies the open number data to the OR circuit 126, while also supplying it to the data conversion circuit 128 as a flat number indicator signal. At this time, the on signal of the switch FLS is supplied to the data conversion circuit 28 as a flat print command signal. The flat number designation signal and flat print command signal supplied to the data conversion circuit 128 are converted into print/paper feed data for flat symbols and sent out. Here, set one of sharp and flat.
To change to the other setting, simply return to C major and then make the setting. In other words, to change the key of the sharp thread to a flat key, press the switch FLS once.
An output signal -%II is generated from ND gate 136, which causes flip-flops 122 and 132 and counters 124 and 134 to be reset via OR gate ]:38. In this state, the key has returned to C major, so all you have to do is press switch FL8 as many times as necessary. In addition, to change the flat key to a sharp key, press the switch F-8H8 once, and the AND gate 140 generates an output signal = 111, which is passed through the OR gate 138. Flip-flop 122 and U 132
Then, the counters 124 and 134 are reset. In this state, the key is returned to C major, so all you have to do is press the edge switch EIH8 as many times as necessary. The sent print/paper feed data is supplied to the printer 144 via the OR circuit 142 in FIG. , the paper feed data is supplied to the paper feed control circuit 148.The print control circuit 146 and the paper feed control circuit 148
generates a coincidence signal IQ when printing and paper feeding control are performed as instructed by the received data. These match signals IQ are supplied to the data generation circuit 112 via the OR gate 150, and in response, the data generation circuit 11
2 generates the following data. By repeating this operation, the key mark of the first bar is printed on the printing paper. However, if the first measure is in C major, no sharps or flats will be printed. When such printing operation is completed, the data generation circuit 11
2 generates an end signal END. This end signal E
ND, is applied to AND gate 152, making it conductive. Thereafter, when the aforementioned print start signal PST and print mode signal PM are generated, the print start signal P8T resets the read address counter 114 in FIG.
4 and the data generation circuit 15 via the AND gate 152.
6. The data generation circuit 156 includes a clef,
It is used to generate print/paper feed data for time signatures, staff, and bar lines, and includes ROM, etc.
When the output signal of the AND gate 152 corresponding to the print mode signal PM is received, print/paper feed data is supplied to the printer 144 via the OR circuit 142. In this case, the flint/paper feed data for the time signature is sent out in accordance with the time signature setting signal T8 from the autorhythm device 40 in FIG. Since the print/paper feed data from the data generation circuit 156 is supplied to the printer 144 via the OR circuit 142, the printer 144 prints staff, bar lines, clefs, etc. in the same manner as in the case of printing the key mark described above. and print the time signature. When these prints are completed, the data generation circuit 156 generates an end signal B N D,. This end signal END is an OR gate 158.160.1
62 and 164 as a read control signal RD to the read address counter 114 of FIG. 5, and in response, the counter 114 generates the first read address signal. This read address signal is supplied to the main memory via the selector which is in the state of selecting input B, so
The first pitch data is read out from the main memory 80 as musical score data MSD. The read pitch data is sent to the data identification circuit +fi in Figure 6.
6 and the data generation circuit 168. The data generation circuit 168 generates musical notes (sharp, flat, natural,
It is used to generate print/paper feed data for (including temporary symbols such as ties), and includes a latch circuit, ROM, etc., and adds sharp, flat, and natural from the OR circuit 126 of the data generation circuit 112. It is designed to receive control data CD for controlling the When the data identification circuit 166 generates the first pitch data detection signal FT in response to the first pitch data, this signal FT
In response, the data generation circuit 168 latches the first pitch data. In addition, the first pitch data detection signal PT is OR
Since the signal is supplied to the counter 114 in FIG. 5 through the gate 164, the first note length data is read out from the main memory 80. Since the data identification circuit 166 generates the first symbol length data detection signal LN according to the first symbol length data, this signal 'r
jL? In response to J, the data generation circuit 168 latches the first note length data. Then, the data generation circuit 168 generates print paper feed data for the first note based on the latched pitch data and note length data. This print/paper feed data is supplied to the printer 144 via the OR circuit 142, so that the first note is printed on the already printed staff on the print paper. After printing the first note, the data generation circuit]68
generates an end signal E N D,. This end signal E
ND, is an OR gate] 58.160.162 and 1
64 to the counter 114 in FIG. 5, the second pitch data and note length data are sequentially read out from the main memory 80 in the same manner as the previous time. Then, the data generation circuit 168 generates print/paper feed data based on the second pitch data and note length data in the same manner as before, so that the second note can be printed. Thereafter, the operations of reading pitch/note length data from the main memory 80 and printing notes are repeated in the same manner. Here, assuming that pitch data (corresponding to the body posture) is read out from the main memory 80, rest length data is read out following that reading. Data identification circuit fi6 generates a rest length data detection signal R9 in response to the rest length data, and data generation circuit +70 latches the rest length data in response to this signal R8. Data generation circuit] 7 () is the print/paper feed for rests. It generates data and includes a latch circuit, ROM, etc. The rest length data latched by the data generation circuit 170 generates the print/paper feed data necessary to draw the corresponding rest, and this data is supplied to the printer 144 via the OR circuit 142, so the print paper A rest is printed on the staff. When the printing of the pause t1 is completed, the data generating circuit 70 generates an end signal ENT'). This termination signal K N I) is the OR gate IfiO1162 and 1
64 to counter 114 in FIG. 5, the next data is read from main memory 80. - As the printing operation of notes or rests progresses as described in (h), the first measure data is read out from the main memory 80, and in response, the data identification circuit 166 outputs the measure data detection signal MS. The data generation circuit 172
supply to. The data generation circuit 172 is for generating print/paper feed data for staff lines and bar lines, and has a configuration as shown in FIG. 10, for example. That is, the measure data detection signal M8 is differentiated by the differentiating circuit 74, and the differentiated output pulse from the differentiating circuit 174 is sent to the address counter 1 via the OR gate 176.
78. Therefore, the first print/paper feed data is read from the print/paper feed data ROM 180 in response to the first read address signal of the counter 178. Then, as described above, when print and paper feed control corresponding to the read data is performed, the O
Match signal EQ from R game) 150 to AND gate 182
is supplied. The coincidence signal EQ is supplied to the counter 17H via an AND gate 82 rendered conductive by the bar data detection signal MS, and further via an OR gate 176. Therefore, data necessary for the next control operation is read from the ROM 18Q. Then, by repeating the same * operation as under JLJ, the bar line at the end of the first measure (beginning of the second measure) and the staff line at the second measure are printed. Note that since the output signal of the inverter 184 which receives the print mode signal PM as input is supplied to the counter 178 via the OR gate 186, the print mode signal -fi PM is %Or, data is not read from the ROM 18Q in the non-print mode. Finally, the end data is read from the ROM I80, and in response to this, the end detection circuit 188 generates an end detection signal. This end detection signal is sent out via an OR gate 186 as an end signal END. This termination i, -i E N D, resets the counter 78 while OR gates 162 and 16 of FIG.
4 to the counter 114 in the fPJ5 diagram. Therefore, the musical score data for the second bar is read out from the main memory 80, and in response to this, the musical score printing operation for the second bar is performed in the same manner as in the case of the first bar. Note that the data generation circuit 172 may be the data generation circuit 5 described above.
The staff/bar line print/paper feed data generation section in 6 may also be used. Thereafter, the musical score printing operations for the third and fourth bars are performed in the same manner as described above. Then, as shown in FIG. 4, when the measure data is read out from the main memo 1J3Q at the end of the fourth measure, the data identification circuit 1 that was counting the number of measures
66 generates a detection signal M, indicating the start of the fifth bar. This detection signal M. is supplied to the data conversion circuit 12P in the data generating circuit 112 of FIG.
The key mark at the beginning of the measure is printed (however,
In the case of C major, this word symbol printing is not done.)
. When this key symbol printing is finished (in the case of C major, upon receiving the detection signal M.), the data generation circuit 112 outputs the completion signal 1!
Since i N D4 is generated, the data generation circuit 156 sends out print/paper feed data in response to this.
Print the bar line at the beginning of the bar, the staff at the 5th bar, and the clef in 5T format. On the other hand, since the detection signal M is supplied as the load command signal LD to the register 190 in FIG. 5, the read address signal corresponding to the bar line data at the beginning of the fifth bar is loaded into the register 90. As described above, this successive address signal is preset in the counter 114 in response to the reprint command signal 1''4RFP.After this, when the data generation circuit 156 generates the end signal END. This signal E N D is supplied to the input terminal 114 of FIG. 5 via the OR gates +58, 160, 162 and 164 of FIG.
From 0 onwards, the musical score data for the fifth measure is read out, and in response to this, the same musical score printing operation as described above is performed. Similar printing operations are performed for the 6th to 8th measures. Thereafter, as shown in FIG. 4, the end data is read out from the main memory 180 at the end of the 8th measure.The 1 data identification circuit 166 generates the end data detection signal FN, and the data generation circuit 192 supply to. The data generation circuit 192 prints and prints for the end line in response to the end data detection signal FH.
It is used to generate paper feed data and includes ROM and the like. Since the print/paper feed data from the data generation circuit 192 is supplied to the printer 144 via the OR circuit 42, an end line 17 is printed in the print operation. When printing of the end line is completed, the data generation circuit 192 generates an end signal E N D,. This end signal E
ND, is supplied to the OR gate 96 in FIG.
M becomes %01. For this reason, the data generation circuit 112,
]56, ]68, 170, 172 and 192 are stopped, and the series of printing operations ends. In the above print mode operation, for example, if the print stop switch PR8 in FIG. 7 is pressed in the middle of the 6th bar in FIG. The 70 knob 102 is reset. Therefore, the print mode signal PM becomes 10I, and the print 4111 operation is stopped in the same manner as in the case of ending printing described above. After this, key settings are made for transposition as necessary. Thereafter, when the reprint command switch REPR shown in FIG.
Set 02. Therefore, the print mode signal P
M becomes slz, data generation circuit 112.156.1
68, ]70.172 and 192 become operational. Further, the ON signal of the switch RBPH is sent out as a reprint command signal RKP, and is supplied to the counter 114 in FIG. 5 as a preset command signal PS. Therefore, a read address signal corresponding to the bar line data at the beginning of the fifth bar is preset from the register 190 to the counter 114, and the bar line data at the beginning of the fifth bar is read from the main memory 80. As a result, the print operation is restarted from the first bar line of the fifth bar in the same manner as described above. In this case, the detection signal M is generated, so that before the bar line of the fifth measure, etc., the kun arrangement is printed except for the C long kun. The key symbol printed at this time is the same as the previous one unless there is a key change, and if there is a key change, it is the one after the key change. The above is the operation of the memory play/print mode when the memory play/print switch MPLP is pressed in FIG. The operations up to storing the musical score data corresponding to are performed in the same manner as described above. In this case, when the correction switch AMS shown in FIG. 5 is turned on, the on signal of the switch AMS is supplied to the correction circuit of the main memory 80 via the OR gate 80a, and the note length data is corrected accordingly. Further, when the memory print switch MPR is pressed, the operation of reading musical score data from the main memory 80 and printing it is performed in the same manner as described above. Note that if there is no data to be read in the main memory 8o even though the print mode is set, the data identification circuit 16 in FIG.
6 detects the absence of data and supplies a detection signal No to that effect to the error message circuit 19111. For this reason,
The error message circuit 198 supplies the print/paper feed data necessary for printing "No DATAJ" to the printer 144 via the OR circuit 142, and when the printing is completed,
is printed. In the above, the embodiments mainly relate to melodies, but the embodiments can also be applied to chords (chords) (see FIG. 4). Furthermore, the melody and chords can be recorded separately, and in this case, if the melody and chords do not match the time signature, an error message to that effect may be displayed. The note length data correction circuit included in the main memo 1180 may be made to function at the time of reading rather than before storage. In this case, the correction switch AMS will be required when the memory block 11 switch MPR is turned on. Just press it accordingly. As described above, according to the present invention, since the keyboard performance can be started in accordance with the autorhythm, the musical score (performance) data with little tempo fluctuation is stored in the storage means such as a memory from the beginning of the performance. For this reason, a row of rests is less likely to be printed at the print start portion, and a high-quality musical score print can be obtained based on the stored data.
