Description

[Detailed Description of the Invention] The present invention relates to a recording and/or reproducing device, and in particular records an information signal on a disc or cylindrical rotating recording medium or traces a recording track on the rotating recording medium to generate an information signal. In a recording and reproducing apparatus, a signal converting section having a signal converting element is slidably provided, and two transport means, first and second, which are selectively connected to the slidable signal converting section are separately provided. Furthermore, by providing a connection switching means for selectively connecting the first and second two transport means to the signal converting section during recording and reproduction and during fast forwarding and fast reversing, the rotating recording medium can be rotated. The signal conversion unit is selectively switched and transferred by each transfer means according to the mode using a source, and a rotation direction switching means is provided between the rotation drive source and the second transfer means, so that the rotation drive source Of course, the connection switching means also enables high-speed fast forwarding and fast reversing, and also detects that the signal converting means has been moved to a predetermined position. By connecting the signal converting means to the first or second transfer means and moving the height position of the signal converting element up and down in conjunction with this, the signal converting means transfers the signal converting element to the recording medium. The signal converting device automatically moves the signal converting element upward when it is detected that the signal converting element is transported by the first transporting means while recording and/or reproducing in the attached state and reaches a predetermined position. The recording medium can be transported at high speed by the second transport means while being separated from the recording medium.

That is, an object of the present invention is to provide a recording and reproducing apparatus that can automatically switch between a recording and reproducing mode and a fast forward/reverse mode, including the vertical movement of a signal conversion element.

Currently, video signals, audio signals, etc. are recorded in a high-density spiral on a disk, and the recording disk is rotated at high speed to trace the signal grooves with a pickup.

Devices for reproducing video and audio signals have been developed.

In this device, during reproduction, the pickup section is moved in synchronization with the rotation of the recording disk in order to linearly track the signal groove.

This device also has a function of rapidly feeding the recording disc in the inner and outer circumferential directions with the pickup section in an inactive state.

Conventionally, in this playback device, the mechanism for moving the pickup section during playback and the mechanism for moving the pickup section at high speed during fast forward/reverse are operated by different drive sources, respectively.

Therefore, since at least two single drive sources are required, the reproducing apparatus becomes expensive, and furthermore, there is a drawback that a complicated circuit is required to control both drive sources.

Furthermore, this configuration has disadvantages such as an increase in the number of component parts and a complicated configuration, which makes it more likely to cause failures, resulting in lower reliability.

The present invention eliminates the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the drawings.

As shown in FIG. 1, the device of the present invention includes a turntable 2 on which a recording disk (not shown) is placed and rotated at high speed by a motor 1, a carriage 4 having a reproduction needle 3, It is roughly composed of a reproduction transfer section 5 that moves the carriage 4 during return, and a fast forward/reverse transfer section 6. In the device of the present invention, both the regeneration transfer section 5 and the fast forward/reverse transfer section 6 are connected to a turntable, as will be described later. It is configured to operate by rotation of the shaft 2a.

Hereinafter, the operation and operation when reproducing a recording disk (not shown) placed on the turntable 2 will be explained in particular with reference to FIGS. 1 and 2.

In the pre-operation mode, the carriage 4 is connected to the reset switch 70 . It is located at position X detected by γ1, and the electrical system is in the form shown in FIGS. 2A and BK.

When the power button 8 is pressed to the lock position, the power switch SW0 in FIG. 2 is closed, and when the play button 9 is then pressed, it is locked to the lock plate 10 and the first play switch S
W2 is closed and at the same time the second play switch SW3 is switched.

For this reason. Motor 1 rotates and clutch solenoid 11
is activated.

Through the rotation of the motor 1 and a belt (-not shown),
The turntable 2 rotates at high speed in the direction of arrow A, and the holder 1
The main drive shaft 16 is rotated at a low speed in the direction of arrow B together with a bevel gear 17 and a worm gear 18 fixed thereto through a first reduction mechanism section 15 consisting of a worm gear 13 and a worm wheel 14 provided in the main drive shaft 16. Ru.

Further, the rotation of the worm gear 18 is transmitted to the feed screw 21 as a low speed rotation in the direction of arrow C via a second reduction mechanism section 20 consisting of the worm gear 18 and the worm wheel 19.

The feed screw 21 and the main guide shaft 22 are held at both ends by a pair of support frames 23a and 23b.

At this time, the clutch bracket 24 provided with the carriage 4vrC moves in the direction indicated by the arrow by the tensile force of the springs 26a and 26b, guided by pins through the elongated holes 25a to 25e, respectively, as shown in FIG. The feed nut 27 is located at the position indicated by the two-dot chain line and is fixed with a screw.
is spaced apart from the feed screw 21.

Therefore, no transfer force is applied to the carriage 4 by the rotation of the feed block 91210.

Also, due to the operation of the clutch solenoid 11.

In the rotational direction switching mechanism section 30 shown in FIG.
- rotated counterclockwise with respect to

A bevel gear 34 and a spur gear 35 that rotate integrally with each other are supported on the shaft 33, and the bevel gear 34 located on the upper side meshes with the bevel gear 17.

Further, a spur gear 36 is provided on one side of the bracket 31.

On the other side, spur gears 37 and 38 are provided so as to mesh with each other, and one spur gear 37 meshes with the spur gear 35, and is a bevel gear driven by the high speed rotation of the turntable 2 as described above. By 170 rotations, each gear 37, 38 is rotating in the direction of the arrow.

Due to the above rotation of the bracket 31, the spur gear 36 meshes with the spur gears 35 and 39, and the rotation direction switching mechanism section 30
The state shown in Figure B is obtained, and the lug-wheel 40 is the spur gear 3.
9, the ladder chain 4 is rotatably driven in the counterclockwise direction in the figure, and is mounted between the other ladder wheel 41.
2 is driven and travels in the direction of the thick arrow A in FIGS. 1, 5, and 6.

Further, at this time, since the clutch bracket 24 is in the position shown by the two-dot chain line in FIG. 3, the regeneration needle 3 is in the raised position as shown in FIG. 8B.

In addition, since the bracket 24 is in the above position, the protrusion 2
4a is fitted into the negative chain portion of the ladder chain 42, and as the ladder chain 420 travels, the carriage 4 is guided by a guide mechanism to be described later and rapidly moves rightward in FIG.

Further, a timing belt may be used instead of the ladder chain 42, and the protrusion 24a may be fitted into a recessed portion of the belt.

When the carriage 4 reaches the regeneration start position Y shown in FIG. 1, a normally closed start switch 44 (Sw3) is switched by the switch bracket 43 provided thereon as shown by the broken line in FIG.

By switching the start switch 44 (SW3), the arm solenoid 45 becomes activated, and at the same time, the clutch solenoid 11 becomes inactive.

By the operation of the arm solenoid 45, the clutch bracket 24 is moved in the direction of arrow E against the springs 26a and 26b to the position shown by the solid line in FIG.
is disengaged from the ladder chain 42, the feed nut 27 engages with the feed screw 21 rotating at a predetermined speed in the direction of the arrow C, and the carriage 4 is subsequently moved by the feed screw 21 to a predetermined minute position in the same direction as above. It is transported at high speed in synchronization with the rotation of the recording disk.

Here, the feed nut 27 is a plate material with excellent wear resistance and a small coefficient of friction, which is bent at one end.
The circular notch 28 on the side facing the feed screw 21 is approximately equal to the lead angle of the feed screw 21 and inclined in the opposite direction.

For this reason, the feed nut 27 is connected to the feed screw 21.
Even if the one-circular notch 28 rides on the peak of the feed screw 21 during engagement with the feed screw 21, the protrusion of the notch 28 falls into the trough, and the notch 2
The entire part 8 quickly falls into the trough and becomes in a normal screwing state, and the carriage 4 starts moving at a very small speed without delay.

Further, when the feed nut 27 is screwed onto the feed screw 21, the recess 28a of the arc notch 28 abuts against the trough.
Both side protrusions 28b.

28c presses the opposing slopes in the adjacent peaks, and the carriage 4 is moved at a very small speed by the feed screw 21 evenly without backlash.

Also, by moving the bracket 24 to the above position, the fourth
As shown in the figure, a rotating lever 47 provided at the rear of the carriage 4 is rotated via a rod 46, and the connecting string 48 is relaxed.

Therefore, as shown in FIG. 8B, the flat plate 49 provided at the front of the carriage 4 starts rotating in the direction of the arrow in the figure with respect to the sharp end 49a due to gravity.

At this time, the air in the space 50 is compressed and gradually escapes through the small gap between the flat plate 49 and the surrounding wall surface, so that the rotation of the flat plate 49 is performed slowly.

For this reason, the regenerated needle 3 has a substantially central portion connected to the other end 49 of the flat plate 49.
b, and is rotated about the shaft support at one end, so that the needle tip 51 is gently placed in a groove at the starting end of a recording disk (not shown) which is rotating at high speed.

As a result, the regenerated needle falling and lifting mechanism section takes the form shown in FIG. 8A.

In the above embodiment, the tip 51 of the reproduction needle 30 relatively traces the signal recording groove of a recording disk (not shown) rotating at high speed together with the turntable 2, and the video and audio signals are reproduced.

Further, when the clutch solenoid 11 becomes inactive as described above, the bracket 31 is rotated clockwise by the spring 32, and the rotation direction switching mechanism 30 is moved to the spur gear 36.
is disengaged from the spur gear 39, while the spur gear 3
8 meshes with the spur gear 39, as shown in FIG. 6A.

Therefore, the spur gear 39 and the rudder wheel 40 are rotated clockwise in the opposite direction, and the rudder chain 43 starts driving in the direction of the large arrow B in FIGS. 5 and 6.

Here, when the spur gear 38 meshes with the spur gear 39 and transmits clockwise rotation thereto, the drive side spur gear 38
Since a force is applied to the driven spur gear 39 in a direction that positively engages the driven spur gear 39, a spring with a small spring tension can be used as the spring 32. As a result, the solenoid 11 is small and has low power consumption. Fewer solenoids can be used.

The carriage 4 moves toward the center of the recording disk (not shown) at a minute speed as the Phoevis 291210 rotates, and when it reaches position Z where the reproduction needle 3 traces the end of the signal recording groove, the protrusion of the switch bracket 43 The portion 43a contacts the switch bracket 60, and the bracket 60 contacts the spring 6.
1, the stopper 62 is rotated by the spring 63, and the bracket 60 is locked with the normally closed end switch 64 (5W5 in FIG. 2) open.

When the end switch 64 (SW5) is opened, the arm solenoid 45 becomes inactive.

Note that at this time, the start switch 44 (SW4) is still locked by the bracket 43 and held in the switching state.

When the arm solenoid 45 is in the inactive state, the clutch bracket 24 is moved by the spring 26a.

26b, the feed screw 2 of the feed nut 27 is moved in the direction of the arrow to the position shown by the two-dot chain line in FIG.
1 is released, and at the same time the protrusion 24a
fits into the ladder chain 42.

Also, due to the above-mentioned movement of the bracket 24. In FIG. 4, the rotating lever 47 is rotated in the opposite direction to the above via the rod 46, and the flat plate 49 is attached to the end 49 via the connecting string 48.
With respect to a, it is sharply rotated in the direction of the arrow in Figure 8.

Therefore, the regenerating needle dropping/lifting mechanism takes the form shown in FIG. 8B.

The regenerating needle 3 is locked to the flat plate end 49b and rotated in a direction to lift the needle tip 51, and the placement of the needle tip 51 in the signal groove is abruptly released.

Here, since the ladder chain 42 is running in the direction of the arrow in FIG. That is, it starts moving at high speed in the direction of the outer circumference of the disk.

When the carriage 4 starts moving, the locking of the switch bracket 60 by the projection 43a is released, but the bracket 60 is held in a locked state by the stopper 62, and the end switch 64 (SW5) is in an open state. There is.

Also, while the carriage 4 is moving to the steady stop position.

The start switch 44 (SW4) is released from the locking by the bracket 43 and is switched and connected as shown by the solid line in FIG.

When the carriage 4 moves to the steady stop position X, a normally open reset switch 70° 71 (SW6 in FIG.
5W7) is switched and closed, and at the same time, the end of the bracket 43 abuts against the unlock bracket 72, and the bracket 72 is rotated in the direction of arrow F.

Rotation of bracket 72 moves rods 73 and 74 in the directions of arrows G and H, respectively.

As the rod 73 moves in the direction of arrow G, the stopper 62 is rotated against the spring 63, and the switch bracket 6
0 is unlocked and rotated to the original position by the spring 61, and the end switch 64 (SW5) is closed.

Here, by closing the reset switch 70 (SW6) and the end switch 64 (SW5), the arm solenoid 45 is activated, the clutch bracket 24 is moved against the spring 26at26b, and the protrusion 24a is fitted onto the ladder chain 42. The connection is canceled.

The high-speed single-loop movement of the carriage 4 stops.

Also, due to the movement of the rod 74 in the direction of arrow H.

Direction changing bracket 75. The unlock bracket 77 is rotated clockwise in FIGS. 1 and 7 via the rod 76, and the lock plate 10 is moved to the right (non-operating direction) in both figures against the spring 78. The button 9 is unlocked at the pressed position and returns to its original position.

When the play button 9 returns, the first play switch SW2 is opened and the motor 1 is stopped.

By stopping the motor 1, the turntable 2 rotates at high speed,
Synchronous rotation of feed screw 21, ladder chain 42
0 running stopped.

The playback device returns to its original stop mode configuration.

Further, when starting reproduction from an arbitrary position on the recording disk, the fast forward button 80 is pressed.

By pressing the fast forward button 80 to the operating position, the play button 9 is engaged with the cooperative lever 81 and pushed into the lock position.

This operation causes the first and second play switches SW2. SW3 is switched.

The first fast-forward switch SW8 is opened, and the second fast-forward switch SW9 is closed.

When the first play switch SW2 is closed, the motor 1 starts rotating, and the turntable 2. Feed screw 21. The ladder chain 42 starts rotating or running.

Further, when the first fast-forward switch SW8 is opened, the circuit including the arm solenoid 45 is opened, and when the second fast-forward switch sW9 is closed, the clutch solenoid 11 is operated.

Therefore, as for the carriage 4, the clutch bracket 24 is held at the position shown by the two-dot chain line in FIG.
The feed nut 27 is unscrewed from the feed screw 21, and the protrusion 24a is fitted into the ladder chain 42.

Further, the one-rotation direction switching mechanism section 30 is in the mode shown in FIG. 6B, and the ladder chain 42 starts running in the direction of the thick arrow A.

As a result, the carriage 4 is rapidly moved in the direction of the playback position in accordance with the travel of the ladder chain 420.

When the locking of the unlock bracket 72 by the switch bracket 43 is released due to the movement of the carriage 4, the restriction of the lock plate 10 to the non-operating position is released.
The play button 9 is locked at the push-in position by a lock plate 10.

When the carriage 4 reaches the desired playback start position on the recording disk (not shown), the push-in operation of the fast forward button 80 is released, the first fast forward switch SW8 is closed, the arm solenoid 45 is activated, and the bracket 24 moves to release the projection 24a from the chain 42, and the feed nut 27 is screwed into the feed screw 21.

Therefore, the carriage 4 is transported at a very low speed in synchronization with the rotation of the recording disk by the feed screw 21, as in the case of play.

Regeneration is performed by the regeneration needle 3 that has fallen into the operating position, and the device enters the regeneration mode.

In addition, when the fast forward button 80 is pressed during the regeneration mode, the arm solenoid 45 becomes inactive as described above, the clutch solenoid 11 is activated, the carriage 4 is released from the minute speed movement by the feed screw 21, and the regeneration is performed. Ladder chain 42 with needle 3 raised
is moved in fast forward mode.

When the pressing operation of the fast forward button 80 is released, the apparatus is placed in the playback mode again.

In addition, when the fast rewind button 82 is pressed during playback mode,
The switch 5W1o indicated by the arrow in FIG. 3 is opened, and the arm solenoid 45 is placed in a non-operating state.

The clutch bracket 24 is moved in the direction of the arrow in FIG.

By this movement of the bracket 24, the screwing of the feed nut 27 to the feed screw 21 is released, and with the regeneration needle 3 raised, the protrusion 24a is attached to one ring of the ladder chain 42 running in the direction of thick arrow B. They fit together, and the carriage 4 is quickly returned toward the steady stop position.

A mode in which the carriage 4 is positioned above the recording disk.

That is, when the start switch SW4 is in the connection mode shown by the broken line in FIG. The part that has already been played will be played again.

Further, if the pressing operation of the quick return button 82 is continued, when the carriage 4 moves to the steady stop position X, the reset switches 70 (SW) and 71 (SW7) are closed, the arm solenoid 45 is activated, and the ladder chain The projection 42a is disengaged from the projection 42, and the quick return operation of the carriage 4 is stopped.

Further, as the carriage 4 moves to the above position, the unlock bracket 72 is rotated, and the lock plate 1 is rotated as described above.
0 is moved to the inactive position, the play button 9 is returned to its original position, the play switches SW and SW3 are switched, the motor is stopped, and the playback device enters the stop mode.

Further, when the eject button 83 is pressed during the reproduction mode, the play button 9 is unlocked by the action of the lock plate 100, and the eject button 83 is locked.

For this reason, play switch SW2 and SW first and second eject switch 5W111 and SW construction.

is switched, and the arm solenoid 45 and clutch solenoid 11 are placed in a non-operating state.

The motor is held in a working position.

As the arm solenoid 45 becomes inactive,
As in the case of quick return described above, the clutch bracket 24 is
Move to the position indicated by the two-dot chain line in the figure and tighten the feed nut 27.
is unscrewed from the feed screw 21, and with the regeneration needle 3 raised, the protrusion 24a engages with the ladder chain 42 running in the direction of thick arrow B, and the carriage 4 quickly moves toward the steady stop position. Transported back.

The carriage 4 returns to the steady stop position without stopping midway, and at this time, the unlock bracket 72 abuts against the switch bracket 43 and rotates, and the lock plate 10 is moved to the non-operating position in the same manner as above and ejected. The button 83 is unlocked and returned to its original position, and the eject switches SW1□ and SW□2 are switched to stop the motor and return the device to its original stop mode.

Furthermore, by further pushing the power button 8, the lock is released and returned to the original position, and the power switch S pre-installation is opened.

Note that if the power supply to the playback device is cut off during playback due to an accident such as a power outage or an erroneous operation such as returning the power button 8, the motor 1 and the arm solenoid 45, which are set to be in the 1 operating mode, are set to the inactive state. .

Here, by converting the solenoid 45 to the non-operating state,
The clutch bracket 24 is a spring 26a.

It is moved to the position shown by the two-dot chain line in FIG. 3 by the tensile force of 26b.

Therefore, in FIG. 4, the flat plate 49 is rotated in the direction of the philtral arrow in FIG. 8 via the rod 46, the rotating lever 47, and the connecting cord 48, and the regenerating needle 3 is raised.

Therefore, the stylus tip 51 remains placed in the signal groove of the rotary disk that can stop its rotation, thereby preventing damage to the stylus tip and the recording groove.

The configuration and operation of the ladder chain drive section will now be explained with reference to FIG. 9.

The chain drive unit supports a spur gear 39 and a rudder wheel 40 on a shaft 52 that is planted on the base 103.
The contact surface between the rudder wheel 40 and the rudder wheel 40 is a dog clutch 53, and the rudder wheel 40 is connected to the spur gear 3 by the elastic force of a coil spring 54 provided in a compressed manner on the upper part of the shaft 52.
The dog clutch 41 crimped to the clutch 9 is in the operating mode.

When the carriage 4 is moved in fast forward and fast reverse directions according to the travel of the ladder chain 420, the ladder wheel 40 is rotated integrally with the spur gear 39 via the dog clutch 41.

However, due to equipment failure or incorrect operation such as overfeeding,
When the movement load of the carriage 4 due to the chain 42 increases, the ladder wheel 40 is moved in the axial direction against the elastic force of the spring 54, and the engagement mode of the dog clutch 53 is released.

Therefore, the rudder wheel 40 is stopped and the spur gear 3
9 rotates independently, thereby preventing damage to each part.

In addition, in FIG. 1, in the first reduction mechanism section 15, a right-handed worm gear is used as the worm gear 13, and the rotation of the worm gear 13 by the turntable 2 causes
The worm wheel 14 is configured to rotate counterclockwise.

For this reason. When the load on the driven part by the worm gear 13 increases, a downward displacement force is applied to the worm gear 13, an upward displacement force is applied to the turntable 2, and its rotation is affected by surface runout, etc. - The problem of instability does not occur.

Next, we will discuss the mechanism for guiding the carriage 4, especially the 10th one.
This will be explained with reference to FIGS. 12 to 12.

As shown in FIGS. 1 and 4, the carriage 4 is guided with its weight supported by a main guide shaft 22 disposed near the feed screw 21 and an auxiliary guide shaft 90 located at a distance from the main guide shaft 22. Ru.

The main guide shaft 22 is connected to the feed screw 2 as shown in FIG.
1 and both ends thereof are held by a pair of support frames 23a and 23b.

The support frames 23a and 23b are each formed by bending a steel plate, and their legs are fixed by a pair of mounting screws 92 via back washers 91.

Note that when installing the support frame 23a y 23b, lightly tighten the mounting screws 92, and then tighten the pair of adjustment screws 9.
3 to move the support frames 23a and 23b up and down to adjust the horizontality of the main guide shaft 22.

Further, as shown in FIGS. 11 and 12, the auxiliary guide shaft 90 has both sides formed as flat parts 90a at each end, and each end is formed into a notch 9 of the support frames 94a and 94b.
5 to hold it.

When installing the auxiliary guide shaft 90, the support frame 94a y
94b is lightly fixed with a mounting screw 97 incorporating a pair of back washers 96, and adjusting screws 98 are threaded through vertically at both ends of the guide shaft 900.
, 99 to finely adjust the height of the guide shaft 90.
The horizontality of the guide shaft 90 is adjusted.

The carriage 4 is guided by a cylindrical housing 100 which is fixed in the horizontal direction with respect to the main guide shaft 22 and is slidably fitted onto the main guide shaft 22 via bearings 101 provided at both ends of the housing 100. The auxiliary guide shaft 90 is guided by a low friction plate 102 attached to the bent portion slidably abutting the auxiliary guide shaft 90.

Therefore, the accuracy of the carriage 4 in the feeding direction is determined by the main guide shaft 22, and the movement in the horizontal direction is guided by the auxiliary guide wheel 90.

Further, in the above-mentioned playback device, the carriage 4 is made into a housing shape by bending a steel plate or the like, and has an inverted U-shape in the side view.1. Each arm is configured to move above and below the turntable 2.

For this reason, the carriage 4 is lightweight, has sufficient strength, and is constructed so that each part can be adjusted.

Furthermore, since the interior space of the carriage 4 is large, the upper arm portion 4a
VC is provided with the regeneration needle 3 and a mechanism for raising or lowering the regeneration needle 3, and the lower arm portion 4b is provided with a drive section by the feed screw 21 and the ladder chain 42, a guide section for the guide shafts 22, 90, and a mechanism for raising or lowering the regeneration needle. A mechanism for operating the lowering mechanism is also provided.

Further, the above-mentioned regeneration device has a motor 1 as a power source on a substrate 103 such as a steel plate. The main parts such as the turntable drive system, rapid traverse drive system, carriage system, guide shaft and feed system, and control system are arranged in a single configuration, making assembly, adjustment, and even repair easy. Furthermore, the connection structure between each system can be simplified.

In addition, in the above embodiment, a device □ for reproducing a disc-shaped recording medium was described, but the device of the present invention uses a cylindrical recording medium with tracks on the circumference,
It is also possible to configure this cylindrical recording medium to be reproduced.

Further, in the above embodiment, the driving force for operating the means for moving the pickup section during playback, fast forwarding and fast reversing is obtained from the turntable rotating shaft, but it may also be obtained directly from the motor that drives the turntable to rotate. Of course it can be done.

In the above embodiment, a reproducing apparatus has been described, but the apparatus of the present invention can be similarly applied to an apparatus for recording information signals on a rotating recording medium.

As described above, according to the recording and/or reproducing apparatus of the present invention, the signal converting means having the signal converting element is slidably provided, and the signal converting means having the signal converting element is selectively connected to the slidable signal converting means. A connection switching means is provided for selectively connecting the two transport means to the signal converting means, and a connection switching means is provided for selectively connecting the two transport means to the signal conversion means. Since the signal converting means is configured to be selectively connected to the first and second transport means depending on the fast reversal mode, the rotation drive source for rotating the rotary recording medium is rotated at a constant speed, It is possible to stably perform the transfer suitable for the mode, and in particular, the transfer during the fast forward/reverse mode can be performed by the second transfer means designed in advance to transfer the signal converting means at a fast speed.

It is possible to avoid inconveniences such as forcibly operating a transfer mechanism designed to perform minute transfer at a higher speed than in the recording/reproducing mode by using a variable speed mechanism, etc. Since the rotation direction switching means is provided in the second transfer means and the operating direction of the second transfer means is switched between fast forward mode and fast reverse mode, fast forward and fast return are possible in which the signal conversion means are moved in mutually opposite directions. In the mode, it is not necessary to reverse the rotational direction of the rotary drive source, and furthermore, at this time, since the connection of the first transfer means to the signal conversion means is switched by the connection switching means, there is no relationship between the first transfer means and the signal conversion means. Furthermore, upon detecting that the signal conversion means has been moved to a predetermined position, the signal conversion means is connected to the first or second transfer means, and the signal conversion means is connected to the first or second transfer means. By configuring the height position of the signal converting element to be moved up and down in conjunction with each other, the signal converting means can perform recording and/or playback with the signal converting element attached to the recording medium while recording and/or reproducing the first signal. When it is detected that the signal converting element has reached a predetermined position after being transported by the transporting means, the signal converting element automatically moves upward and is moved away from the recording medium at high speed by the second transporting means. It's going to happen.

That is, it has the advantage that switching between the recording/reproducing mode and the fast forward/reverse mode can be performed automatically, including the vertical movement of the signal conversion element.
