A program for controlling the CPU 21 is written in the ROM 22. The CPU 21 detects the presence / absence of a signal from an external device connected to the input port 24 according to this program, and performs processing, calculation, data transfer, data transfer, and storage corresponding to the detected signal, if necessary. Supply the processed output to the output port 25, and those requiring a latch are output after being latched.

Emitting diode to indicate that the music selection switch 2 ₀ was music selection provided corresponding to _2-6 to the output port 25 37- ₀
～37- _6, repeatedly provided corresponding to the instruction switch 33 repeatedly emitting diode to indicate that the instruction has been made
38, a tone arm drive circuit 39 for driving the tone arm in the radial direction of the turntable, a tone arm descending drive circuit 40 for driving the tone arm in the direction of the turntable,
Turntable drive circuit 41 Yes connected, the light emitting diode _37-0 ～37- _6, 38 turned on by the output from the output port 25, off, blinking is controlled, the tone arm drive circuit 39 through the output port 25 The tone arm descending drive circuit 40 and the turntable drive circuit 41 are driven by the output of the HL, LH, and HH potentials that are output as a high potential output through the output port 25. The tone arm is lifted above the turntable by a spring attached to the tone arm.

6. Read the presence / absence of a signal from the detector mounted on the record board.
Emitting diodes 37- _0, ..., ～37- _6, 38, tone arm drive circuit 39, tone arm vertical drive circuit 40, the turntable drive circuit 41 latches the output is supplied from the output port 25. When the HL output is supplied, the tone arm drive circuit 39 drives the tone arm from the outer side to the inner side of the record board, and when the LH output is supplied, the tone arm is moved from the inner side to the outer side of the record board. The tone arm is stopped when the LL output is supplied. Further, the pulse generator 36 generates a pulse having a constant frequency by moving the tone arm at a constant speed. Output pulses from the pulse generator 36 are counted in a counter area provided in the RAM 23. Further, this counting is performed reversibly according to the moving direction of the tone arm. That is, when the tone arm moves from the outer circumference side to the inner circumference side of the record board, it counts up, and when it moves from the inner circumference side of the record board to the outer circumference side, it counts down. Further, when down-counting, the tone arm is located away from the turntable and the tone arm is located away from the turntable, which is instructed by the CPU 21, and the up-counting and down-counting are also instructed by the CPU 21. On the other hand, the inter-track detection device 35 detects the inter-track by moving the tone arm when detecting the inter-track, and the inter-track detection output, that is, the signal which detects the end of the tune of each music is read into the CPU 21, and the CPU 21 detects the inter-track. The count value obtained by counting the output pulses of the pulse generator 36 when the end of song detection output is generated by the detection device 35 is provided in the song position detection area provided in the RAM 23 in correspondence with the song number attached to the song on the record board. It is stored as the end position data of the song. This is usually done.

On the other hand, the music selection switch 2 ₀ ～2- ₆ is adapted to the program number on the record board, corresponds to the first piece of music to seventh music. Sequentially according to the order you want to play the key switch 2 ₀ ～2- _6, to press. By pressing this, the performance song
The music selection is registered as shown in the flowchart of the figure.

That is, the music selection switch 2 ₀ ... or _2-6 is turned on is detected (step a) CPU 21, or during the performance is judged by detecting whether the tone arm is in the rest position (step b ). Instructions for registering the musical composition are given during non-performance. Therefore, in step b, it is checked whether or not the music is not being played, and following step b, music selection registration has already been performed (step c). The check in step c can be judged by whether or not the song number data is stored in the later-described song selection storage area K provided in the RAM 23. When not already been made music selection registered in the step c, the music selection switch 2 ₀ ... which is pressed subsequent to step c, the music number data corresponding to _2-6 is stored in the music selection storage area K (step d) . This storage address is an address designated by the stored contents of the order storage area S provided in the RAM 23, and the song selection storage area K is designated from the first address. Subsequent to step d, the music number data stored in the music selection storage area K in step d is copied to the remaining music storage area N provided in the RAM 23 (step e). Copying of the song number data in the remaining song storage area is sequentially performed from the first address. Emitting diode _37-0 in response to the music number data stored in the remaining songs storage area N Following step e, ..., turns the 37- ₆ (step f). Subsequent to step f, the contents stored in the sequence storage area S are incremented by "+1" to indicate the music selection storage area K.
The address designation of "(1)" is performed (step g), and then the song number data in the order storage area S becomes a predetermined value (in the present embodiment, data up to 7 songs can be registered, so data exceeding the 7th song). Checked (step h). When it is less than the predetermined value in step h, step a is executed after step h, and when it exceeds the predetermined value in step h, the music selection registration routine ends.

On the other hand, when the already music selection registration is made in step c, the music selection switch 2 ₀ ... being pressed into the music number data stored in the music selection storage area K subsequent to step c, in response to 2- ₆ It is checked whether there is song number data to be played (step i). This check is the song number data and song selection storage area K corresponding to the pressed song selection switch.
It is performed by sequentially comparing the stored music number data. If the same song number data does not exist in step i, step d is executed subsequently to step i.

Therefore, by the steps a to h, the music selection switch _2-0
～2- ₆ light emitting diodes 37- ₀ specified track number data in the music selection storage area according to a specified order until 7 tracks each press corresponds to the stored and music selection has been song -, ..., 37- ₆ is turned Will be.

When the same track number data is present in step i music selection switch 2 ₀ ... pressed, the music number data corresponding to _2-6 is detected and addresses of the music selection storage area K stored (step j ), The song number data stored at that address is erased (step k). Then the light emitting diode _37-0 in response to the music corresponding to the music number data is erased in step k, ..., 37- ₆ is turned off (step l). Subsequent to step l, in order to prevent the address where the song number data erased in step k was stored from being empty, the song number data stored after the erased song number data is the previous one. It is stored in the address (step m). Subsequent to step m, step l
The storage data stored in (1) is copied to the corresponding address in the remaining music storage area N (step n). Subsequent to step n, steps m and n are executed over all the song number data stored in the song selection storage area K after the address next to the address detected in step j (step o),
When steps m and n have been executed all over, the contents of the sequential memory S are decremented by "-1" (step p), and after step p is executed, step a is executed.

Therefore song selection switch 2 ₀ ... corresponding to the song that has already been registered, when pressing the _2-6, the pressed music selection switch 2 ₀ ..., the music number data is track selection storage area K corresponding to 2- ₆ And the song number data stored in the remaining song storage area N and stored after the next address of the song number data is 1
One repeat would be stored in the address climbed, the pressed music selection switch 2 ₀ ..., registration of a song corresponding to _2-6 are deleted. The music selection switch 2 ₀ ... are simultaneously pressed, a light emitting diode responsive to the music corresponding to 2 ₆ 37- _0, ..., 37- ₆ shows that registration is deleted turned off state from a lighting state To be done.

Also, when the newly pressed music selection switch 2 ₀ ..., _2-6, already the music selection switch corresponding to any songs that do not match the song number data is also registered in the music number data that has been registered is not present 2 ₀ ..., _2-6 if it has been pressed, will be registered in the music selection storage area K and Zankyoku storage area N. In this case, the registered position is the address next to the address where the registered song number data is stored.

From the above, it is clear that the registration can be changed or added arbitrarily.

When it is determined in step b that the performance is being performed, a direct music selection routine described later is executed.

Next, the memory call routine will be described with reference to FIG. When the memory call instruction switch 32 is pressed
It is detected that the CPU 21 outputs the memory call instruction switch 32, and the memory call routine shown in FIG. 4 is executed.

When the pressing of the switch 32 is detected (switch aa), it is checked whether there is stored data in the remaining music storage area N (switch ab). Residual music storage area N at switch ab
If there is no stored data in it, the memory call routine ends. Further, if there is stored data in the remaining music storage area N, following step ab, the contents stored in the performance music storage area described later in the memory call storage area M provided in the RAM 23 and serving as an address counter of the remaining music storage area N. Is copied (step ac). Next, the timer 26 is set (step ad). Now, assume that the timer is set to 2 seconds. It is detected whether a counter (hereinafter referred to as a blinking interrupter) provided in the RAM 23 that counts the divided clock pulses and acts as a blinking interrupter that operates with the value of the predetermined bit, from "0" to "1", following step ad Yes (step ae). When the flashing interrupter is "1" light emitting diode _37-0 in response to the music corresponding to the music number data of the remaining songs storage area N in the address specified by the contents of the memory call storage area M, ..., a 37- ₆ Turn off the light (step af). The light emitting diode 37- ₀ when flashing interrupter is "0" in response to the music corresponding to the music number data of the remaining songs storage area N in the address specified by the contents of the likewise memory call storage area M, ..., 37 -Keep lit ₆ (step ag). Then the set time of timer 26, that is, 2
During the second, that is, ae to ag are executed (step ah).
When the set time of the timer 26 has elapsed, "+1" is added to the contents of the memory call storage area M (step ai). Then, it is checked whether or not the content of the memory call storage area M exceeds a predetermined value. If it does not exceed the predetermined value, step aa is executed, and if it exceeds the predetermined value, the memory call routine ends (step aj ). The predetermined value in step aj is the value of "last address + 1" of the music number data stored in the remaining music storage area.

Therefore, by executing the memory call routine, the light emitting diode 37-responding to the music corresponding to the music number data stored in the youngest address of the remaining music storage area N at the repetition cycle of "0" and "1" of the blinking interrupter. _0, ..., 37- ₆ 2 seconds, repeated blinking, then the light emitting diode 37- ₀ responsive to the music corresponding to the music number data stored in the next address of the remaining songs storage area N, ..., 37- ₆ 2 seconds, repeated blinking light-emitting diode 37- ₀ responsive to the music corresponding to the last music number data follows Similarly Zankyoku storage area N, ..., 37
- ₆ repeats flashing. That is, the light-emitting diode 37- ₀ corresponding to the music selection registered music -, ..., 37- ₆ will be repeated 2 seconds tsuzuic Flashing music selection is the order, the light emitting diode 37- _0, ..., 37- ₆ The blinking order indicates the order of music selection. As will be described later, when the performance is performed, the music number data which has been registered and the performance of which has ended is erased. In this case, therefore, the registration order of the remaining music can be known.

Next, performance, that is, record reproduction will be described with reference to FIGS.

When the start / stop instruction switch 34 is pressed, its output is read into the CPU 21, the performance is stopped when the performance instruction has already been given, and the performance instruction is given when the performance instruction has not been given (step ba ). Step
When a performance instruction is issued at ba, it is detected whether the tone arm position is at the rest position (step b
b). When the tone arm is not in the rest position in step bb, the auto cut state (step bc) is set and the performance is not performed. When the tone arm is in the rest position in step bb, it is checked whether the record board is placed on the turntable (step bd). When it is detected in step bd that the record board is not placed, the automatic cut state (step bc) is set and the performance is not performed. When it is detected that the record board is placed in step bd, a high potential signal is supplied to the turntable drive circuit 41 through the output port 25 to drive the turntable, and at the same time, the tone arm drive circuit 39 outputs HL. Is supplied to drive the tone arm toward the inner circumference of the turntable (step be). Following step be, the size of the record board is detected, and data corresponding to the record board size is stored in the RAM 23 (step bf). Then, it is checked whether the song number data is stored in the song selection storage area K (step bg). When it is detected in step bg that the data is stored in the music selection storage area K, the output from the inter-track detector 35, that is, the inter-track detection output obtained from the difference in the reflectance of the light on the record board is detected. The integrated value of the output pulse of the pulse generator 36 at the time of reading and outputting the detection between songs is stored in the RAM 23 in correspondence with the song number on the record board as the end position data of the song (step bh), and the tone arm returns. The process is performed until the position is reached (step bi). Therefore, the ending position of each song on the record board is stored over all the songs on the record board.

Then, it is checked whether or not the music number corresponding to each music number data stored in the music selection storage area K and the remaining music storage area N exceeds the music number detected by steps bh and bi, and the music number data is recorded. When the corresponding song number exceeds the detected song number, the song number data corresponding to the exceeded song number is deleted, the next address is moved up to that address and stored, and so on. form a light emitting diode 37- ₀ responsive to the music corresponding to the music number data to which the are deleted, ..., 37- ₆ is turned off (step bj). By executing step bj, the numbered songs exceeding the number of songs engraved on the record are no longer registered.

After step bj, "1" is transferred to the performance music storage area P set in the RAM 23 (step bk), and the remaining music storage area stored in the address specified by the storage content of the performance music storage area P is stored. The tone arm is driven to the end position of the previous song of the song (playing song) corresponding to the song number data of N (step bl). The drive of the tone arm is stopped when the end position of the previous song in step bl is reached (step
bm). The tone arm is stopped by supplying the LL output from the output port 25 to the tone arm drive circuit 39. Following step bm, a high potential output is supplied to the tone arm lowering drive circuit 40 via the output port 25, and the tone arm is lowered to the record board surface (step b
n). Then, the light emitting diode 37- ₀ responsive to the tune in step bl, ..., 37- ₆ are made to the blinking state from the lighted state (step bo). This flashing light-emitting diodes 37 - ₀ explained in memory call routine, ..., it is performed similarly to the flashing _37-6. With blinking interrupter in example step bo the upper bits and the counter constituting the flashing interrupter and 2 bits, the light emitting diode _37-0 at half the frequency of cases in the memory call routine, ..., 37- ₆ blinking Will be repeated. Emitting diode 37- ₀ in response to the song songs corresponding to the music number data stored in the remaining songs storage area N from the time the clear as steps bn is performed from above is played are played, ..., 37 -By blinking ₆ you will know the number of the performance song.

Following step bo, the normal tracking drive continues until the tone arm reaches the end position of the song being played (step bp), and at step bp it is detected that the tone arm has reached the end position of the song being played. When
A low potential output is supplied to the tone arm lowering drive circuit 40 via the output port 25, and the tone arm is raised by the force of the spring (spring bq). Then the light emitting diode _37-0 in response to the song being played, ..., 37- ₆ light emitting diodes 37 - ₀ had repeated flashing i.e., ..., 37
- ₆ is to turn off (i.e., br). Then, the song number data in the remaining song storage area N stored in the address designated by the stored content of the playing song storage area P is cleared (step bs). Therefore, in step bs, the registration in the remaining music storage area N corresponding to the music being played is erased. Next, the content stored in the performance music storage area P is incremented by "+1" (step bt), and then it is checked whether or not the music number data stored in the remaining music storage area N is exhausted (step bu). Whether or not there is no song number data in the remaining song storage area N in step bu is checked by checking whether or not all the data stored in the address designated by the song number contents in the playing song storage area is "0". When there are remaining songs, step bl is executed following step bu.

Therefore, when there is no remaining song in step bu, it indicates that all the songs registered for song selection have finished playing,
In this case, following step bu, repeat routine bv
Is performed.

Here, before the description of the repetition routine, the repetition number designation routine will be described with reference to FIG.

When the repeat instruction switch 33 is pressed, it is detected by the CPU 21 (step ba), and the repeat instruction is detected (step db). That is, it is determined whether the content of the repeat instruction flag provided in the RAM 23 is "1" or "0", and when it is "1", the content of the repeat instruction flag is set to "0" by pressing the repeat instruction switch 33 ( Step dc) and ends. When the content of the repeat instruction flag is "0" in step db, the repeat instruction switch 33 is pressed to set "1" to the content of the repeat instruction flag and the repeat instruction is given (step de). Following step de, the repeat count is set in the repeat count storage area R provided in the RAM 23 (step df), and the repeat count designating routine ends.

Now, assuming that the repeat count storage area R is 4 bits,
In step df, all bits are set to "1" and the number of repetitions is set to 16 times.

Next, the iterative routine will be described with reference to FIG.

The execution of the repeat routine (step bv) shown in FIG. 6 starts by checking whether the content of the repeat instruction flag is "1" (step ea). If the content of the repeat flag is "0" in step ea, step ea
Then, auto cut (step bc) is executed. Therefore, in this case, the repetition is not performed. When the content of the repeat instruction flag is "1" in step ea, following step ea, all the stored contents of the music selection storage area K are copied to the remaining music storage area N in the storage order (step eb). This is because all stored contents in the remaining music storage area N are cleared when step ea is executed. After step eb, the content of the repeat count storage area R is incremented by "+1" (step ec), and subsequently to step ec, it is checked whether the content of the repeat count storage area R is "1" (step ed). Ie step
In ed, it will be determined whether it is the last iteration.

If the content of the repeat count storage area R is other than "1" in step ed, it is checked whether the content of the repeat count storage area R is "0" (step ee). Step
When the content of the repeat count storage area R in ee is other than "0", step bk is executed subsequent to step ee. In step ee, the repeat count storage area R
When the content of is "0", auto cut (step bc) is executed following step ee. If the content of the repeat count storage area R is "1" at step ed, the light emitting diode 38 is made to blink following step ed (step ef), and then step bk is executed. However, when the content of the repeat count storage area R becomes "1", it is the time of the 16th repeat by counting even one time before entering the repeat routine. At this time, the light emitting diode 38
Is blinking. Therefore, the last repetition is notified by blinking the light emitting diode 38. When the content of the repeat count storage area R becomes "0", it means the 17th repeat, in which case the automatic cut is performed and no repeat is performed and the repeat ends.

As is apparent from the above, if the repeat instruction switch 33 is repeatedly instructed until the performance of the last music in the first performance of the music selected and registered is completed,
When the performance of all the music selection registration song is finished, the light-emitting diode 37- ₀ corresponding to all of the music selection registration song, ..., _37-6 is turned on, then,
The tone arm moves to the position of the first registered music selection, the second performance is started again, the performance is repeated for a preset number of times, and the light emitting diode 38 is turned on at the last performance. Flashes to indicate that it is the last time.

Further, when the number of repetitions is set to an infinite number of times, it is impossible to avoid wear of the needle tip and the record board due to forgetting to stop. However, since the setting is made a finite number of times as in the present embodiment, it is possible to avoid wear of the needle point and the record board due to forgetting to stop or the like. In addition, the blinking of the light emitting diode is notified at the time of the last repeat, and when the repeat is continued, the repeat instruction is canceled once and the repeat instruction is given again, so that the finite number of repeat operations can be performed again. Become.

Next song selection during playback switch 2 _0, ... will be described with reference to FIG. 9 direct music selection routine work when pressing the _2-6.

When it is detected in step b in FIG. 3 that the music is being played, it is checked whether or not there is music number data stored in the remaining music storage area N following step b (step fa).

When there is no song number data stored in the remaining song storage area N in step fa, the process ends after step fa. Music selection switch 2 ₀ which is pressed in step a following step fa When in step fa songs number data stored in the remaining songs storage area N, ..., song remaining songs stored in response to the _2-6 It is checked whether the music corresponds to the music number data stored in the area N and whether the music is before the performance (step fb). In step fb,
The pressed music selection switch 2 _0, ..., when the song responding to _2-6 is earlier corresponding to the music number data stored in the remaining songs storage area N and playing, tone arm subsequent to step fb The output to the descent drive circuit 40 is changed from a high potential to a low potential to raise the tone arm (step fc).
Then, the tone selection switch _2-0 , whose tone arm was pressed,
..., it is moved to the end position before song tracks that respond to _2-6 (step fd), light emitting diode 37- ₀ in response to the song interlaced to reach step fd, ..., turns off the 37- ₆ ( Step fe). Next, tone arm descending drive circuit 40
The output to is changed from low potential to high potential, and the tone arm is lowered (step ff). Thus pressed music selection switch _2-0, ..., when the song the song corresponding to the _2-6 has not been played yet a song that had been pre-song selection registration,
The pressed music selection switch 2 _0, ..., so that the music corresponding to _2-6 is played immediately.

Also, the music selection switch _2-0 pressed in step fb,
... not a song corresponding to the music number data tracks responsive to _2-6 is stored in the remaining songs storage area N, or when not the previous song played, subsequent to step fa, song currently playing Is checked (step fh). If it is not the song currently being played at step fh, the process ends after step fh. At step fh, if the song is currently being played, then the tone arm is raised as in step fc following step fh (step fi). Following step fi, the tone arm is moved to the end position of the previous piece of the piece being played (step fj), and then step ff is executed.
Therefore, by the steps fb, fh, fi, fj, ff, the performance of the music being played is stopped midway and the music is played again from the beginning of the music. Therefore, the music selection switch 2 _0, ..., music selection switch 2 ₀ in response to the music that is music selection registered while playing the song that is music selection registered in _2-6, ..., the by pressing the _2-6 Regardless of the previous music selection order, music is played in response to the newly pressed music selection switch. In addition, the light emitting diode corresponding to the skipped song selection song is turned off, and the appearance of the song is apparently finished.

(Effect of the Invention) As described above, according to the present invention, by pressing the music selection switch in response to an unplayed music registered in the music selection during the performance of the music selected and registered, the music selection switch is pressed. The specified song will be played from the beginning. The same is true when the music currently being played is designated by the music selection switch.
