Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a player device, and particularly to a player device that plays a plurality of songs recorded on a record in any order. It is something.

(b) Prior Art Conventionally, a so-called program automatic performance player device that plays a plurality of songs recorded on a record in an arbitrary order is known, for example, from Japanese Patent Application Laid-open No. 57-1999.
One disclosed in Publication No. 33461 is known.

According to such a player device, it is possible to play songs recorded on a record in any order, and in the programmed songs, by operating an operation button after a start operation, the programmed order can be played. You can lead-in to any song without any connection.

However, in such player devices, the operation mode of the operation button is controlled to be switched in connection with the start operation (for example, the program key button is switched between program memory use and skip play lead-in use). For example, it was not possible to change the contents of the program after the operation.

(c) Problems to be Solved by the Invention Even after the start operation, the operation mode of the skip operation means can be changed, so that, for example, the contents of the program can be changed.

(d) Means for Solving the Problems The present invention provides a memory means for storing a plurality of different states of a tone arm in a player device configured to play a plurality of songs recorded on a record in an arbitrary order. and a skip operating means, the player being configured to determine a memory output from the memory means and cause the skip operating means to operate in a different operating mode, for example, for skipping or for program shifting. It provides equipment.

(E) Effect According to the player device of the present invention, the skip operation means is operated when the memory means stores that the tone arm is in either the playing/lead-in or cueing-down state. Then, the skip operation means is operated as a skip lead-in, and the tone arm is set in a lead-in state or a lead-out state, and the memory means stores that the tone arm is in a state other than the above state. When the skip operating means is operated, the skip operating means can be used to skip only programs or shift only programs. At this time, the tone arm is not controlled in any way and maintains its original state.

(F) Embodiment FIGS. 1 to 4 are diagrams showing an embodiment of the present invention.

In the figure, 1 is a player body, 2 is a record player lid rotatably attached to the player body 1 via a hinge (not shown), 3 is a stop and right search button, 4 is a start and left search button, 5 is a cueing button, 6 is a repeat button, 7 is a skip button, and 8 is an intro scan button, which are used to play a programmed song for a short time (for example, 15 seconds) and check the content of the song. 9 is a program key button, and 10 is a display element provided corresponding to each program key button.

Incidentally, the player main body 1 is equipped with a turntable 11 that is rotationally driven by a motor (not shown), and is also provided with a dust cover switch 12 for detecting a closed state of the player lid 2. There is.

On the other hand, the player lid 2 is provided with a linear tracking arm device 13 on its inner surface.

Such a linear tracking arm device 13 is provided with a carriage 16 that moves on guide members 14 and 15 that are arranged opposite to each other as shown in FIG. A tone arm 17 equipped with a track interval detector is supported by a pivot bearing (not shown) so as to be rotatable in vertical and horizontal directions. Further, a plunger 18 for moving the tone arm 17 up and down is arranged in the carriage 16, and the plunger 18 drives a lifter shaft 20 facing the lower surface of the tone arm 17 via a cueing mechanism 19. There is. Additionally, a sensor arm 21 rotates together with the tone arm 17.
and a tracking sensor 2 that detects a tracking error of the tone arm 17 using a photodetector 22.

On the other hand, the rotational force of the motor 24 as a drive source for moving the tone arm 17 is applied to a belt 28 that is stretched between a pulley 25 provided on the motor shaft and a pulley 27 provided on the shaft of the worm gear 26. The drum 3 is coaxial with the gear 29 that is transmitted to the worm gear 26 through the worm gear 26 and meshes with the worm gear 26.
0. A rope 3 is hung between the drum 30 and other pulleys 31, 32, 33.
4 to move the carriage 16. 35 is an end detection switch.

Further, a photodetector 3 is mounted on the shaft of the worm gear 26.
A slit disk 37 is provided to be rotated between the light receiving element and the light emitting element 6, and the photodetector 36 and the slit disk 37 act as generators of position pulses that indicate the position of the tone arm 17. It consists of 38.

FIG. 3 is a block diagram of a player device according to the present invention, in which numeral 39 is a microcomputer serving as a control circuit, 40 is an input/output circuit, 41 is a central control unit (CPU), and 42 is a read/write board in which a program for the CPU 41 is written. Only Memory (ROM), 43
44 is a memory (RAM) for sequentially storing programmed songs, and 44 is a memory (RAM) for determining whether the repeat button 6 has been operated.
So, when repeat is ON, the flag is set to 1, and when repeat is OFF, the flag is set to 0. 45 is a memory (RAM) for storing which number of programmed songs is currently being played, and 46 is a memory (RAM) for storing which mode the tone arm is currently in. , for example, when the tone arm 17 is on the armrest, it will be 1, and when the tone arm is up somewhere other than the armrest and is in standby mode, it will be 2.
, 3 when the record is playing, 4 when the tone arm is up and moving to the next song, 5 when the tone arm is up and moving back to the armrest, and 5 when the tone arm is down. When the tone arm is in transition from the up state to the up state, 6 is stored, and when the tone arm is in transition from the up state to the down state, 7 is stored. 47 is a counter that counts pulses from the position pulse generator 38.

Next, the operation will be explained with reference to a flowchart.

When the skip button 7 is operated, the CPU 41
The contents stored in the memory 46 (i.e., the current operation mode of the tone arm) are read out and determined, and this is determined as 3 (playing state), 4 (leading-in movement in progress), or 7 (queuing down movement in progress). In some cases, it works as follows.

First, by checking the flag in the memory 44, it is determined whether the repeat button 6 is being operated.

At this time, the flag is 1 (i.e. repeat ON)
If so, the skip button 7 acts as a skip lead-in.

That is, for example, the program stored in the memory 43 is □1□3□5□7□9, and the contents of the memory 45 are 3
(That is, when the fifth song, which is the third song, is being played or lead-in), the content of the memory 45 is changed to 4 by operating the skip button 7, and the tone arm 17 is lead-in to the seventh song. At this time, if the tone arm is in the lead-in mode, it will directly lead in to the seventh song, and if it is in the performance and down operation mode, it will lead in to the seventh song after the up operation.

Note that at this time, the program stored in the memory 43 remains unchanged.

By the way, if the program is not stored in the corresponding address after operating the skip button 7 (for example, if it is □1□3□5□-□-)
In connection with the operation of the skip button 7, the contents of the memory 45 are set to 1, and the lead-in is performed to the first song.

Also, the flag in the memory 44 is 0 (i.e., repeat
OFF), the skip button 7 functions for program shift and skip lead-in. Note that the content of the memory 45 at this time is fixed to 1.

That is, the contents of the memory 43 are □1□3□5□7□9, and 1
When a song is being played or the lead-in is in progress, if you operate the skip button 7, the tone arm will move to 3.
As the song is lead-in to the song, the contents of the memory 43 become □3□5□7□9□-. That is, at this time, by operating the skip button 7, a skip lead-in and a program shift can be achieved.

By the way, the contents of the memory 43 are, for example, □1□−□−□
−
If there is no program to be skipped, as in □-, there is no corresponding program even if the skip button 7 is operated, so the tone arm is operated in return.

Next, the contents stored in the memory 46 are 1
(state in armrest position), 2 (up and waiting state), 5 (return operation state), 6
(up operation in progress), it operates as follows.

Flag of memory 44 is 1 (i.e. repeat ON)
At this time, the skip button 7 functions for program skipping.

That is, the contents stored in the memory 43 are □1□3□5□
7
If it is □9, only the display elements 10 corresponding to each song number will be lit up sequentially in response to the operation of the skip button 7. At this time, the contents of the memory 43 do not change and remain □1□3□5□7□9.

The flag in memory 44 is 0 (i.e. repeat
OFF), the skip button 7 functions as a program shift button.

That is, if the contents of the memory 43 are □1□3□5□7□9, by operating the skip button 7 once, the display element for the third song is turned on, and the contents of the memory 43 are □3□5□. It is changed to 7□9□-. or,
When the operation is performed one more time, the display element for the fifth song is turned on and the contents of the memory 43 are changed to □5□7□9□-□-.

Note that even if the skip button 7 is operated at this time, the tone arm 17 is not controlled in any way.
Retains the state before operating the skip button.

(G) Effects of the Invention As described above, the player device of the present invention is a player device that plays a plurality of songs recorded on a record in an arbitrary order, and is capable of storing a plurality of different states of the tone arm. This is because it comprises a memory means and a skip operation means, and is configured to determine a memory output from the memory means and cause the skip operation means to operate in a different operation mode, for example, for skipping or for program shifting. , it is possible to make a single skip operation means compatible with a plurality of operation modes, which is useful because it can improve operability.
