Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a first recording and reproducing mechanism having at least a reproducing function (preferably a recording and reproducing function) and a second recording and reproducing mechanism having at least a recording function (preferably a recording or reproducing function). A tape recorder, a VTR, an EVR, etc. capable of performing a dubbing operation in which the reproduction signal reproduced by the first recording and reproduction mechanism is recorded by the second recording and reproduction mechanism. The present invention relates to a recording/reproducing device.

In this type of recording/playback device (for example, a tape recorder equipped with two magnetic recording/playback mechanisms), during dubbing, the playback signal played by one magnetic recording/playback mechanism is recorded by the other magnetic recording/playback mechanism. That's what I do.

Therefore, when starting dubbing, it is necessary to put one magnetic recording/playback mechanism into the playback state and the other magnetic recording/playback mechanism into the recording state at the same time. Sound fluctuations were likely to occur due to the start-up characteristics of the drive motors of each magnetic recording and reproducing mechanism.

The present invention has been invented to correct the above-mentioned defects.If the pause release button is operated at the start of dubbing and the pause states of the first and second recording and reproducing mechanisms are released simultaneously, It is possible to start the reproduction of one recording/reproducing mechanism and the recording of the other recording/reproducing mechanism in a timely manner, and at this time, it is possible to avoid being particularly affected by the start-up characteristics of the drive motors of these recording/reproducing mechanisms. In addition, even during dubbing, it is possible to form a non-recorded part on the recording medium that is being recorded, or to cut unnecessary parts of the recorded content.

Furthermore, the first and second recording media can be individually put into a paused state and can be released individually or simultaneously even when dubbing is not being performed.

Also, the playback output from the recording/playback head 281 is guided to the changeover switch 298 in the same way as in the above-mentioned normal playback, and then passes through this switch to the volume adjuster 277, where the volume is adjusted. It is mixed with the input and added to mixup 278.

Since the output of the automatic volume adjustment limiter 279 is applied to the output side of the mixing amplifier 278 via the changeover switch 296, the output of the mixing amplifier is applied to the limiter output, and then passes through the changeover switches 301 and 302 to the line amplifier. Added to 285.

The output of the line amplifier 285 is applied to a limiter 279 and also to a recording equalizer 287 via a changeover switch 297.

The output of this recording equalizer is applied to the left channel recording/reproducing head 310 of the recording/reproducing circuit of the right recording/reproducing mechanism which is set to the recording state, and is recorded on a magnetic tape.

Note that one end of this recording/reproducing head 310 is connected to a changeover switch 31.
It is grounded via 1.

○4x speed dubbing In this 4x speed dubbing state, as in the case of 1x speed dubbing described above, the left side recording and playback mechanism 3 is put into the dubbing playback state, and the right side recording and playback mechanism 4 is put into the dubbing recording state. ing.

Therefore, for the operation, the left and right side recording and playback mechanisms 3
and 4 into the playback state and recording state, respectively, as in the case of normal playback and normal recording, and at the same time press the 4x continuous dubbing button 24.

In addition, when the 4x speed dubbing button 24 is pressed, mechanically, except for the dubbing button and its locking mechanism,
This is similar to the case of double speed dubbing.

In this quadruple speed dubbing state, the motor circuits (not shown) of the recording and playback mechanisms 3 and 4 are switched, and the rotational speed of the drive motors 47 and 48 shown in FIG. 1 increases approximately four times. Therefore, the running speed of the magnetic tape has increased approximately four times.

In this state, the external input is not mixed with the playback output, and the output of the automatic volume adjustment IJ mitter 279 is added to the playback output.

I try not to let that happen.

For this reason, in this 4x speed dubbing state, the 10th
Compared to the state shown in the figure, the 1x speed/4x speed changeover switches 299 to 301 have been switched to the other switching state.

The reproduction output from the recording/reproducing head 281 is guided to the changeover switch 299 as in the above-mentioned normal reproduction, and then passes through this switch to the volume adjuster 284, where the volume is adjusted.

Next, the signal is led to the changeover switch 301 via the changeover switch 300, and then guided to the recording/reproduction head 310 through the same route as in the case of 1x speed dubbing, where it is recorded on a magnetic tape.

Next, the pose state will be described with reference to FIGS. 1, 2, 7, and 8.

The pause state only stops the tape running of the left and right recording/playback mechanisms 3 and/or 4 which are in the recording or playback state.

Therefore, in switching to the pause state, no circuit switching operation is performed, and only the separation of the pinch rollers 43 and/or 44 from the capstans 41 and/or 42 and the stopping of rotation of the reel shaft are performed. be.

In this embodiment, illustration of stopping the reel shaft in conjunction with the pause buttons 15 and 16 is omitted, as this is obvious to those skilled in the art.

0 pose In the stop state shown in Fig. 1, press the play buttons 9, 1.
0 and/or record buttons 5 and 6 to enter the playback or recording state, and press the pause button 15 in this playback or recording state, as shown in FIGS. 1, 7, and 8.
The left recording and reproducing mechanism 3 is held in a pause state.

Note that Figures 1, 7, and 8 show both recording and playback mechanisms 3.
This is a case in which the pause button 15 is pressed with 4 and 4 in the recording state, thereby performing continuous recording as will be described in detail later.

However, since the pause operation is the same in these figures, the pause operation will be explained below with reference to these figures.

When the pause button 15 is pressed, the pause operation plate 65 integrated with the pause button 15 moves the guide groove 68, guide pin 71 and guide hole 83.
It moves downward against the spring 73 by the guide action of each of them.

Therefore, the lock pin 81 integrated with the actuating plate moves downward while moving in the inclined groove portion 75a of the cam groove 75 formed in the pause lock plate 90.

Therefore, the pause lock plate 90 rotates clockwise in FIG. 8 against the spring 87 using the mounting pin 93 as a fulcrum by the lateral length of the inclined groove portion 75a.

When the pin 81 reaches the lower end of the inclined groove part 75a, the pause lock plate 90 rotates slightly counterclockwise in FIG. and reaches the base of the convex groove portion 75c.

Next, when the pause button 15 is released, the pause operation plate 65 is moved slightly upward by the traction force of the spring.

Therefore, the pause lock plate 90 further rotates counterclockwise in FIG. 8 about the mounting pin 93 by the pulling force of the spring 87, so that the lock pin 81 reaches the locked position shown in FIG.

As described above, when the pause actuating plate 65 moves downward in FIG. 8, the intermediate lever 99 whose one end is engaged with the engagement hole 97 rotates clockwise in FIG. 7 about the pin 101 as a fulcrum. from the chain line position to the solid line position.

Therefore, this intermediate lever uses its other end to press the pressed portion 105a of the sliding plate 105 to the left in FIG. 7, so that this sliding plate is in the position indicated by the chain line in FIG.
It moves forward from the position shown in the solid line (that is, the forward movement position shown in FIG. 2).

Therefore, the pressing protrusion 105b of the sliding plate 105 presses one end of the pinch roller actuating lever 115, so that this lever pivots from the position shown in FIG. 1 to the position shown in FIG. 2 using the pin 117 as a fulcrum. do.

For this reason, the pinch lever 53 is pressed by the other end of the pinch roller operating lever 115, so that it rotates counterclockwise in FIG. 1 about the pin 45 as a fulcrum.

Therefore, the pinch roller 43 separates from the capstan 41, and the left recording/reproducing mechanism 3 enters a pause state.

As mentioned above, when the sliding plate 105 moves forward to the position shown in FIG.
Also press one end of 3.

Therefore, this lever rotates clockwise in FIG. 1 using the pin 112 as a fulcrum, and rotates forward from the backward movement position shown in FIG. 1 to the forward movement position shown in FIG. 2.

In this case, if at least one of the left and right side recording/playback mechanisms 3, 4 is not in the recording state, the stopper portions 127a, 128a of at least one of the recording/playback switching rods 127, 128 are in an L-shape. The stopper portion 114b of the shaped lever 114 is pressed against the stopper portion 114b.

Therefore, the clockwise movement of this L-shaped lever 114 in the clockwise direction in FIG. prevent the movement of

Next, when the pause button 15 is pressed again, the lock pin 81 in the lock position shown in FIG.
Move to the other base of c, so pause lock plate 9
0 rotates in the counterclockwise direction in FIG. 8 about the mounting pin 93 as a fulcrum by the pulling force of the spring 87.
1 reaches the end of the horizontal groove portion 75b of the cam groove 15 (that is, directly below the inclined piece portion 85).

Next, when the pause button 15 is released, the pause operation plate 65 attempts to move back upwards due to the pulling force of the spring 73, so the lock pin 81 presses the inclined piece 85 to the left in FIG.

Therefore, the pause lock plate 90 swings clockwise in FIG. 7 with the mounting pin 93 as a fulcrum, as shown by the chain line in FIG.
The lock pin 81 moves to the upper end of the cam groove 75 and is inserted into the cam grooves 7 and 5 again at this position, and at the same time, the pause operation plate 65 completely moves back.

In this case, the pause lock plate 9 with the mounting pin 93 as the fulcrum
Since the rotation of the pin 81 in the counterclockwise direction in FIG. 8 is restricted by the stopper 92, the pin 81 is reliably inserted into the cam groove 75.

Note that when the pause operation plate moves back, the intermediate lever 99 also moves back, so the traction force of the traction coil spring 119 and the restoration of the linear spring 57, which is hooked between the rotating lever 113 and the chassis 30, are By force, the sliding plate 105,
The pinch roller operating lever 115, the pinch lever 53, the pinch roller 43, and the rotating lever 113 all move back,
For this reason, the above-mentioned pause state is released.

Note that when the other pause button 16 is pressed, the pause operation described above is slightly different.

That is, the locking and unlocking operations of the pause operating plate 66 are similar to those described above, but when the pause operating plate 66 moves downward, one end of the intermediate lever 100 is pressed by the suppressing protrusion 66a of this plate. Ru.

Therefore, this lever moves clockwise in FIG. 7 using the pin 102 as a fulcrum against a spring (not shown), so that the other end of this lever touches the pressed portion 106a of the sliding plate 106.
is pressed downward in Figure 1.

Therefore, the pressing protrusion 106b of the sliding plate 106 pushes the pinch roller operating lever 116 onto the pin 11 as in the case described above.
8 as a fulcrum, the pinch roller 44 receives a force separating it from the capstan 42 via an intermediate lever (not shown) and a pinch lever 54, respectively.

Further, the pressing protrusion 106b of the sliding plate 106 rotates the rotating lever 113 in the forward direction as in the case described above.

Next, when the pause button 16 is pressed again, the pause operation plate 66 moves upwards in the same way as in the case described above, so that the stopper action of the intermediate lever 100 by its pressing protrusion 66a is released, and the spring is thereby released. (not shown).

Therefore, due to the traction force of the spring 119 and the restoring force of the linear spring 58, the sliding plate 106 and the pinch lever operating lever 1
16, the above intermediate lever (not shown), pinch lever 54
, the pinch roller 44, and the rotating lever 113 all move back, so that the above-described pause state is released.

Note that when one or both of the left and right recording/reproducing mechanisms 3 and 4 are in the above-described pause state, when the pause release button, that is, the start button 22 is pressed, both of these pause states are released.

That is, when the start button 22 shown in FIG. 7 is pushed in the direction of arrow A, this button rotates counterclockwise in FIG. 7 using the pin 101 as a fulcrum.

Note that the button 0% 22 formed at the bottom of this button
Since the lock release plate 251 is inserted into the engagement hole 260 of the lock release plate 251, the lock release plate moves leftward in FIG. 7 against the spring 256 due to the rotation described above and reaches the position shown by the chain line.

This forward movement causes the pressing portion 251a of the lock release plate to
, 251b push the upper ends of the pose lock plates 90° and 910, respectively, so these pose lock plates are attached to the mounting pins 93,
It rotates clockwise in FIG. 7 with 94 as the fulcrum and reaches the position shown by the chain line.

Therefore, even if the lock pins 8L82 provided on the pose actuating plates 65 and 66 are locked by the pose lock plates 90 and 91, these locks are released by the above-mentioned rotation of these pause lock plates. The pause operation plates 65 and 66 are moved back by the traction force of the springs 73 and 740.

Therefore, even if the recording and reproducing mechanisms 3 and 4 are in a paused state, the paused state is canceled in the same way as in the case described above.

Next, a case will be described in which continuous recording is automatically performed using the two recording and reproducing mechanisms 3 and 4 in sequence.

O Continuous recording In this continuous recording state, both recording and playback mechanisms 3,
4 may be placed in a recording state, and one of the recording and reproducing mechanisms 3 or 4 may be placed in a pause state as in the case described above.

Figures 2, 3, 6B, 6C, 7 and 8
The figure shows a continuous recording state in which the left recording and reproducing mechanism 3 is in a pause state.

In this state, the recording/reproducing switching rods 127 and 128 move leftward from the position shown in FIG. 1 to the position shown in FIG. 2, so that the stopper portions 12 formed on these rods
7a and 128a have both moved to positions where the stopped portion 114a of the L-shaped lever 114 cannot be stopped.

Therefore, as in the pause state described above, the rotation lever 113 is in the second position.
When the sliding plate 121 is rotated forward to the position shown in the figure, the sliding plate 121 moves forward from the retracted position shown in FIG. 1 to the forward position shown in FIG. 2 by the pulling force of the spring 130.

At this time, the stopped portion 121a of this sliding plate, whose advancement was prevented by the stopper portion 114a of the L-shaped lever 114 and the rotating lever 113, is moved to the stopper portion 11.
4a, the L-shaped lever 114 rotates clockwise in FIG. 1 about the pin 112 and reaches the position shown in FIG. 2.

As described above (when the sliding plate 121 moves forward, the actuating levers 133 and 134 whose one ends are engaged with the engagement grooves 135 and 136 formed in the sliding plate, respectively, move around the pin 125 as a fulcrum. Figure 1: Rotates clockwise and counterclockwise, respectively.

Therefore, the relief levers 141 and 142 whose upper ends are engaged with the notches 137 and 138 of these actuating levers can be moved from the position shown in Fig. 6A (i.e., the position when not in continuous recording mode) to Figs. 6B and 6C. Then, it rotates forward using the pin 155 as a fulcrum to the position shown in FIG. 7 for continuous recording.

The relief lever 141 in the position shown in FIG. 6A is in a state of performing a relief operation, and the relief lever 141 in the position shown in FIG. 6B, FIG. 6C, and FIG.
The relief lever 141 in the position shown in the figure is in a state where it is not performing a relief operation.

That is, since the worm 171 is constantly rotating at a constant speed due to the rotation of the pulley 173 driven at a constant speed by the motor 47, the worm gear 175 meshing with the worm
, and in turn, the cam portion 177 integrated therewith rotates at a constant speed with the pin 183 as a fulcrum.

Due to this rotation of the cam portion, the profiling surface 1γ0 of the profiling lever 168 is intermittently pushed by the cam portion, so that the profiling lever 168 performs a swinging motion about the pin 159 as a fulcrum.

Note that FIG. 6A shows a state in which the profiling lever has moved most downwardly, and FIG. 6C shows a state in which it has moved most upwardly.

Due to this swinging motion, the traction lever 156 performs a reciprocating linear motion in the left and right direction in FIGS. 6A and 6B.

Note that in the state shown in FIG. 6A, the relief is LL/bar 14.
1 presses down the traction lever 156 against the spring 163, so that the engaging claw 158 formed at the tip of the traction lever engages the towed plate 14.
It does not engage with the engagement protrusion 148 or 149 of No. 6.

On the other hand, as shown in FIGS. 6B, 6C, and 7, if the release lever 141 is in the continuous recording position (i.e., the position where no release operation is performed), the engagement claw of the traction lever 156 158 engages with the engagement protrusion 148 of the towed plate 146.

Therefore, as long as the towed plate 146 can move rearward (to the left in FIG. 6B) by the traction force of the spring 258, the towed plate 1
46 remains in the above-mentioned engaged state, and as shown in FIGS. 6B and 6.
As shown in Figure C, a similar movement is performed in conjunction with the aforementioned reciprocating linear movement of the traction lever 156.

The above-described operation is performed in exactly the same manner for the other before-end detection mechanism 151.

Tested hanging ring mechanism 166 shown in FIGS. 3, 4, and 5.
At 167, constant speed pulley 1 is driven by motors 47 and 48.
86 is driven at a constant speed, the constant speed wheels 196 and 19 to which the rotation of this constant speed pulley is transmitted via the friction plate 203
7 will rotate at a constant speed.

On the other hand, the speed change wheel 205 receives the rotation of the reel stand pulleys 220 and 221 on the supply reel side via the belt 229, pulley 218, rotating shaft 226, pulley 216, belt 214, speed change pulley 193, and friction plate 204, respectively. ,these.

Attempts to rotate according to the rotation speed of the glue base pulley.

However, since the constant speed wheels 196, 197 and the variable speed wheel 205 are connected to each other by the arcuate frame 188 and the engagement pin 189, whichever one has a higher rotational speed rotates with the other.

Therefore, in the left side recording and reproducing mechanism 3 (the right side in FIG. 3, which is a bottom view), which is in a pause state, the supply reel shaft is stopped, so the variable speed pulley 193 is stopped, and therefore the speed is constant. Wheel 196 rotates with variable speed wheel 205 .

Therefore, the engaging pin 189 is inserted into the arcuate groove 1 as shown in FIG.
Since it is always located at the rear end of 88, the fitting hole 2 of constant speed wheel 196
23 and the fitting hole 224 of the speed change wheel 205 do not overlap each other vertically, so that the fitting protrusion 232a of the fitting lever 232 fits into these holes.

It will not fit.

In addition, in the right side recording/playback mechanism 4 in the recording state, while there is a large amount of magnetic tape wound around the supply reel, the supply reel shaft, and eventually the reel stand boo! Since the rotation speed of J221 is small, a variable speed pulley is used.

The rotational speed of wheel 193 is also low, so that constant speed wheel 197 rotates together with variable speed wheel 205.

Therefore, as in the case described above, the fitting protrusion 231a of the fitting lever 231 does not fit into the fitting hole 223 of the constant speed wheel 197 and the fitting hole 224 of the variable speed wheel 205.

However, as the magnetic tape runs, the rotational speed of the supply reel shaft and, ultimately, the reel stand pulley 221 gradually increases.

Therefore, when recording is performed for a predetermined period of time and the magnetic tape travels a predetermined distance, and therefore the remaining tape wound around the supply reel decreases by a predetermined rate, the rotational speed of the reel stand pulley 221 and, by extension, the speed change pulley 193 decreases to a predetermined value. reach the value.

For this reason, the rotational speed of the variable speed wheel 205 is the same as the rotational speed of the constant speed wheel 197, and the former eventually becomes larger than the latter.

Therefore, the speed change wheel 205 finally rotates together with the constant speed wheel 197, so as shown on the left side of FIG.
The engagement pin 189 of 05 is connected to the arcuate groove 188 of the constant speed wheel 197.
The front end in the clockwise direction in FIG. 3 is contacted.

For this purpose, the fitting hole 223 of the constant speed wheel 197 and the variable speed wheel 20
Since the fitting holes 224 of No. 5 overlap each other vertically,
The fitting protrusion 232a of the fitting lever 232 fits into these holes as shown on the left side of FIG.

This fit means that the before-end of the magnetic tape has been detected.

This "before end" refers to a predetermined position on the magnetic tape approximately 30 seconds to 3 minutes (e.g. approximately 2 minutes) before the end of recording or playback of the magnetic tape, and from the end of the magnetic tape. Approximately 75c
This corresponds to a location before rrL to 450 CrrL (for example, about 300 crfL).

Due to the above-mentioned fitting, the fitting lever 232 rotates counterclockwise in FIG. Move to the left in the diagram.

Therefore, the stopper lever 237, which has been prevented from moving forward by this pin, rotates clockwise in FIG. 3 using the pin 242 as a fulcrum by the pulling force of the spring 244, and reaches the position shown by the solid line.

For this reason, the stopper pin 248 provided on the towed plate 147 is caught by the stopper portion 237a of this stopper lever when moving from the bottom to the top in FIG.
Since it is prevented from moving upward in the figure, its forward position (6th
(a little to the right of the position shown in Figure B).

Therefore, the traction lever 1 continues to perform reciprocating linear motion.
When the engaging claw 158 of 56 moves forward to the left in FIG. When engaged, the towed plate 147 is pulled to the right as shown in FIG. 7, and moved further forward than the forward position.

Therefore, the suppressing protruding plate portion 146a clearly shown in FIG.
51 moves forward to the right in FIG.

Therefore, the pause state is canceled in the same manner as when the previously described pause release button 22 is pressed, and the left side recording/playback mechanism 3 also enters the recording state.

By canceling the pause state described above, the rotating lever 113 is rotated counterclockwise in FIG. 121 stopped part 12
Press 1a.

Therefore, this sliding plate, the operating levers 133, 134, and the release levers 141, 142 move back, respectively.

Furthermore, when the sliding plate 121 moves back, the suppressing part 121d provided on this sliding plate also moves back upward in FIG. It is rotated clockwise again using the pin 234 as a fulcrum.

Therefore, the stopper pin 239 provided on this lever
presses the stopper lever 237 to rotate it back counterclockwise about the pin 242, and as a result, the entire before-end detection mechanism 151 is restored to its initial state.

On the other hand, the right side recording/playback mechanism 4 is turned off by an auto-shaft-off mechanism (not shown) which is operated by a timer or mechanical delay means that detects that a certain period of time has elapsed since the before-end detection. Must be able to switch to the stop state.

), or may be automatically shut off by a conventionally known auto shut off mechanism (not shown) that detects the tape end independently of the before-end detection described above.

Next, after replacing the magnetic tape, the right side recording and playback mechanism 4
If the recording pause state is set, continuous recording can be performed further, and continuous recording can be performed by repeating the above-mentioned operation thereafter.

Since the present invention has the above-described configuration, when dubbing, the first recording/reproducing mechanism is put into a playback pause state by operating the first pause button, and the second recording/reproducing mechanism is put into a playback pause state by operating the second pause button. By placing the second recording/playback mechanism in a recording pause state, and then operating the pause release button to release the playback pause and recording pause states of the first and second recording/playback mechanisms at the same time, the first The start of playback of the recording/playback mechanism and the start of recording of the second record/playback mechanism can be performed with good timing, and at this time, they are not particularly affected by the start-up characteristics of the drive motors of these recording/playback mechanisms.

Also, even during dubbing, if the first recording/playing mechanism that is currently playing is paused, a non-recorded portion can be formed on the recording medium that is being recorded by the second recording/playing mechanism. Conversely, if the second recording/reproducing mechanism during recording is temporarily stopped, unnecessary portions of the recorded content reproduced by the first recording/reproducing mechanism can be cut and recorded on the recording medium.

Furthermore, by individually operating the first or second pause button even when not dubbing, the first or second recording/playback mechanism can be individually paused or released as necessary. If the first and second recording and reproducing mechanisms are both in a paused state, they can be brought into the recording or reproducing state at the same time by operating the pause release button.
