Description

[Detailed Description of the Invention] The present invention relates to an auto player in which the auto-start operation of a record player is linked to a timer, and includes at least the following:
The present invention relates to an auto player in which a tone arm is dynamically driven to a playing position when power to the player is supplied by a timer.

Many of the conventionally known auto players always
Only when the start switch is operated after the power switch is turned on, the lead-in mechanism is automatically activated and guides the tone arm to the playing position.

However, in such conventional auto players, the mechanism operated by the start switch is mechanical in order to automatically operate the lead-in mechanism at a predetermined time using a timer. So,
The only way to operate the mechanical mechanism is to use a plunger or the like.

This invention maintains both the timer start switch and the power switch in the on state, and uses a separately provided timer to automatically supply power to the circuit that drives the auto lead-in mechanism, etc., and automatically starts the tone arm. To provide a new auto player which electrically performs automatic performance in conjunction with a timer when in a performance state.

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 shows an autoplayer A according to the present invention in which power is supplied via a timer B, and Fig. 2 shows an outer casing 1 of the autoplayer A including a power switch 2, a timer start switch 3, and an autoplayer. This shows a device equipped with a touch switch 4 for starting, and when both the timer start switch 3 and the power switch 2 are turned on in terms of the circuit, autoplay, that is, automatic performance can be performed at a predetermined time set by the timer. It's becoming like this.

FIG. 3 shows a conventional control circuit for manually starting an automatic performance using such a switch, and it mainly consists of a switching circuit and a hold circuit 9, and the hold circuit uses a flip-flop circuit 5. , this clip-flop circuit 5 is connected with a trigger output circuit 6 for inverting its operation and a switching circuit 7 driven by the output of the flip-flop circuit 5.

Furthermore, a reset circuit 8 is connected to the flip-flop circuit 5 as shown in the figure, which operates to maintain the clip-flop circuit 5 in a predetermined constant inversion state after the power switch is turned on.

The switching circuit 7 described above is connected to the output side Q or Q of either of the two transistors constituting the flip-flop circuit 5, and the reset circuit 8 is also connected to either Q or Q accordingly. After the power switch is turned on and there is no trigger output from the trigger output circuit 6 to the flip-flop circuit 5, the stop state is maintained.

That is, when the power is turned on, automatic performance is in a stopped state.

Therefore, when the touch switch shown in FIG. 3 is operated in such a state, the state of the clip-flop circuit 5 is reversed by the trigger from the trigger output circuit 6, and Q becomes '0''. , the switching circuit 7 is driven to put the auto player into a playing state.

However, in the present invention, it is necessary to use a timer to automatically start the automatic performance, so it is necessary to turn on and off as shown in Figure 4.
A timer start switch 9 (indicated by the operation button 3 in FIG. 2) that performs an OFF operation is connected between the reset circuit 8 and the flip-flop circuit 5.

Further, the output of the reset circuit 8, which is activated by turning on the power switch 2, is selectively supplied to either Q or Q of the flip-flop circuit via the timer start switch 9, and the movable contact piece 9a is selectively supplied to either Q or Q of the flip-flop circuit. When connected to the fixed contact 9b side, the page is set to (t 0j31) to start automatic performance, and when connected to the fixed contact 9c side, Q is set to O''', that is, the page is set to '1''. The automatic performance is kept in a stopped state, and the automatic performance becomes possible only when the touch switch 4 is manually operated.

Therefore, by providing the above-mentioned timer start switch 9, it is possible to perform automatic performance using the auto player using the timer.

Therefore, according to the circuit configuration shown in FIG. 4, at all times, that is, when the timer is not in use, the movable contact piece 9a of the timer start switch 9 is connected to the fixed contact 9c.
is connected to the OFF position, the Q of the clip-flop circuit 5 is in the O state, and the page " is in the L state,
A predetermined circuit operation of the switching circuit 7 is stopped to stop automatic performance.

In other words, when the power is turned on, automatic performance is reset to a stopped state.

Therefore, in this state, by manually operating the touch switch for automatic performance start, the trigger output circuit is driven, thereby setting the Q of the flip-flop circuit 5 to 11". Automatic performance begins only after the page is set to O''' and the switching circuit 7 is driven.

On the other hand, if you want to use a timer to stop automatic performance,
A timer is connected to the power supply circuit, and the movable contact piece 9a of the timer start switch 9 is connected to the fixed contact 9b to turn it on.

In this way, if the power switch 2 is operated to close the circuit and the contacts of the timer (not shown) are set to close at a predetermined time, after the set time, When the timer is activated and the power is turned on, the output of the reset circuit 8 is the timer start switch 9.
is applied to the Q of the flip-flop circuit through the Q of the flip-flop circuit to bring it to the state of 0'''' and to turn the switching circuit 7 to 1.
The automatic performance will start fully automatically.

Each state of the clip-flop circuit 5 can be arbitrarily and alternately inverted by applying a trigger output from the trigger output circuit 6.

As described above, the present invention includes a flip-flop circuit, a timer switch and an auto-start switch respectively connected to the control input side of the flip-flop circuit, and when there is no output from the timer switch, the auto-start The switch fixes the flip-flop circuit in a predetermined state and allows the breaker to automatically start playing.

On the other hand, when the timer switch is closed, the clip-flop circuit can be fixed in the predetermined state by the output of the timer switch, so that the player automatically plays.

In this way, not only does it normally have the function of an auto player, but it can also be used as a wake-up auto player by setting a timer, and its uses are wide.
