Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a head cleaner mainly for cleaning a rotating magnetic head of a player to which a magnetic tape cartridge for video or audio is applied. In particular, the object is a reel-to-reel type head cleaner that cleans the magnetic head while running a cleaning tape.

[Conventional technology]

There are two main types of head cleaners: one is a stop cleaning type that cleans the magnetic head while the cleaning tape is stationary, and the other is a reel-to-reel type that cleans the magnetic head while the cleaning tape is running.

As a representative example of the former method, Japanese Patent Application Laid-Open No. 56-105321
It is known from the publication No. In this case, since the contact point of the cleaning tape with the magnetic head remains constant, the surface to be cleaned of the tape tends to get dirty quickly and is prone to wear and tear, and the dirt that was previously wiped off may re-adhere to the head surface. There is a problem with this point.

Therefore, the latter reel-to-reel system is practical, in which the magnetic tape in a real magnetic tape cartridge is simply replaced with a predetermined amount of cleaning tape. In this case, the cleaning tape travels along the same moving path as the magnetic tape and is wound onto the take-up reel. The tape passes between the pinch roller and the capstan, and receives the main running force when passing between the two.

[Problem that the invention seeks to solve]

In the above-mentioned reel-to-reel type head cleaner, a relatively thin tape material such as woven fabric or non-woven fabric is used as the cleaning tape, and it is difficult to use a thick tape material such as leather. When the tape thickness exceeds a certain value, the pinch roller separates from the capstan and is no longer driven to rotate, making the cleaning tape run unstable.
In other words, the cleaning tape is moved only by the winding force of the take-up reel, which has a small rotational torque, and the pinch roller presses the tape against the capstan and obstructs the tape's running, so the winding torque is insufficient. This is because stable tape feeding becomes impossible.

Furthermore, in the case of a wet type in which a cleaning liquid is also used, the rotational resistance at the head increases significantly, making it difficult to perform cleaning in a reel-to-reel manner.

Incidentally, the cleaning tape is required to have both appropriate softness and sufficient tensile strength so as not to damage the magnetic head, excellent ability to capture micro dust, and no change due to friction. In this respect, relatively thin tape materials such as woven fabrics cannot be said to be good tape materials. At present, relatively thick tape materials such as leather or composite tapes made of layers of different materials are evaluated as more suitable tape materials. For these reasons, the appearance of a reel-to-reel type head cleaner that can be applied regardless of tape thickness, has a simple structure, and is inexpensive has been eagerly awaited.

The present invention has been proposed from this viewpoint, and the objects of the present invention are to be able to ignore the thickness of the cleaning tape, to perform wet cleaning, and to have a simple structure and low cost. The object of the present invention is to obtain a reel-to-reel type head cleaner.

Another object of the present invention is to drive the take-up reel so that sufficient take-up torque can be obtained and the tape can be fed at a suitable speed.

Still another object of the present invention is to start and stop the running of the cleaning tape, automatically store the tape 2 pulled out of the case, or roll the take-up reel 4.
The purpose is to enable automatic rewinding of the tape 2 that has moved to the side in the same way as in a real magnetic tape cartridge.

[Means for solving problems]

In FIG. 1, the head cleaner of the present invention has a basic structure in which a feed reel 3 on which a cleaning tape 2 is wound and a take-up reel 4 are rotatably housed in a cartridge case 1. Preferably, each reel 3, 4 and each edge of the cleaning tape 2 are connected via, for example, translucent lead tapes 2a, 2b, and this allows the tape to start and stop running, and to be pulled out of the case. To automatically store stored tapes in the same way as a real magnetic tape cartridge. In order to load the tape, a part of the moving path of the cleaning tape 2 is set at the front edge of the tape loading pocket 14, and for the tape moving path near the take-up reel 4, this is the pocket for the capstan. Set it to avoid 15.

The tape is fed by using the rotational force of the capstan C or the pinch roller R, which has a large rotational torque. When the pinch roller R is used as the drive source, specifically, the drive mechanism 5 is arranged so as to face the capstan pocket 15, and when the head cleaner is loaded into the player, the drive mechanism 5 is in circumscribed contact with the pinch roller R. Set to be driven. Then, in conjunction with the movement of the pinch roller R into the pocket 15, the drive mechanism 5 circumscribes the take-up reel 4 disposed inside the case, and transmits the rotational power of the pinch roller R to the take-up reel 4. Do it like this. The drive mechanism 5 allows the pinch roller R to circumscribe and transmit power to the take-up reel 4 only when it enters the capstan pocket 15, that is, only when in use, and allows the take-up reel 4 to be freely moved when rewinding the tape. Make it rotatable to reduce resistance.

[Effect]

When the head cleaner is loaded into the player and the playback button is operated, the pinch roller R enters the capstan pocket 15, circumscribes the capstan C, and at the same time circumscribes the drive mechanism 5, winding the rotational power via the drive mechanism 5. Give it to take reel 4.
As a result, the cleaning tape 2 is wound onto the take-up reel 4, and is moved while being in circumscribed contact with the magnetic head H to clean the head surface. The cleaning tape 2 wound on the take-up reel 4 and the cleaning tape 2 pulled out of the case are such that, for example, when a player operates a stop operation, the player drives the pay-out reel 3 to automatically rewind the loaded tape. Use it to roll up and store inside the case. At this time,
The drive mechanism 5 is separated from the take-up reel 4 and becomes freely rotatable.

〔Effect of the invention〕

In the present invention, the tape moving circuit is set to avoid the capstan pocket 15, so that the cleaning tape 2 does not pass between the capstan C and the pinch roller R. After that,
The take-up reel 4 can be driven via the drive mechanism 5 by using the power of the capstan C or the pinch roller R, which has a large rotational torque.

Therefore, it is possible to obtain a reel-to-reel type head cleaner which is not affected by the thickness of the cleaning tape 2 and can also be used in conjunction with wet cleaning which has a high rotational resistance. As a result, it is possible to obtain a head cleaner with a simple structure and low cost, in which a thick tape material having excellent performance, such as natural or artificial leather, is applied to the cleaning tape 2 as required.

The take-up reel 4 receives power from a drive rotating body such as a capstan C or a pinch roller R, which has a large drive torque, and is moved through a drive mechanism 5 to the take-up reel 4.
Since the take-up reel 4 can be driven with the necessary and sufficient rotational torque and at a suitable feed speed, the tape can be properly fed without applying an abnormal load to the magnetic head.

Since the drive mechanism moves toward and away from the take-up reel 4 in five strokes in conjunction with the movement of the pinch roller R into and out of the pocket 15, the reel 4 can be freely rotated during rewinding. Therefore, the player's original functions, such as automatic rewinding of the tape 2 pulled out of the case during loading and rewinding by operating the rewind button, can be used as is, just like a real magnetic tape cartridge. Easy to handle and easy to use.

Embodiment 1 FIGS. 1 to 5 show a first embodiment of the present invention. The head cleaner in this case is exemplified as one compatible with a tape player to which a VHS type magnetic tape cartridge is applied, and inside a cartridge case 1 having the same external shape and function as a magnetic tape cartridge, Basic components such as the cleaning tape 2, a feed reel 3 on which the tape is wound, and a take-up reel 4 are housed. A drive mechanism 5 for transmitting the power of the pinch roller R to the take-up reel 4 is provided in the cartridge case 1.

In Figures 2 to 4, the cartridge case 1 is made of plastic upper and lower cases 1a and 1b.
The case has tape loading pockets 13, 14 and a capstan pocket 15 recessed in its front surface, and a front lid 16 for opening and closing the front surface of the case. The front lid 16 is pivoted to the closed position and locked in the closed position, similar to that of a real magnetic tape cartridge, and when loaded into the player, the lock is automatically released by a member on the player side. and then rotate to open upward.

Positioning holes 17 and 1 are provided in the bottom wall of the lower case 1b in correspondence with standard members such as a positioning pin on the player side, a reel brake release pin, a reel drive shaft, and a lamp 45 for detecting the start and end ends of the tape.
7, release pin hole 18, drive shaft insertion hole 19, 19,
Lamp holes 20 and the like are formed in predetermined shapes at predetermined positions. A groove for preventing erroneous loading is formed in the center of the lower surface of the lower case 1b in a manner that crosses the lamp hole 20 back and forth as specified. These holes and grooves are mainly for loading the cartridge case 1 into the player without any trouble.

An optical path P 1 for tape start end detection and an optical path P ₂ for tape end detection are set on lines connecting the lamp hole 20 and the lamp windows ₁₂ near the front end of the left and right side walls of the cartridge case 1, respectively. S ₁ and S ₂ are player-side tape end detection members arranged outside the case on the respective optical paths P ₁ and P ₂ . Note that some players are equipped with an interlock that prevents the player from switching to playback mode unless the optical path _P1 for detecting the beginning of the tape is blocked.
Regarding the detection of the tape starting end, there may be cases where the optical path _P1 is not secured within the cartridge case 1.

The cleaning tape 2 is made of artificial leather of uniform quality, excellent durability, and little change over time.
Specifically, the contact surface side of the magnetic head H has raised leather fibers entwined with each other, and is made of a strong material having appropriate softness and sufficient tensile strength.
Each edge of the tape body is connected to a take-up reel 4 and a feed reel 3 via transparent lead tapes 2a and 2b.

Incidentally, cleaning tape 2 and each lead tape 2
a and 2b are removably connected via plastic hooks 8, so that the cleaning tape 2 can be easily replaced. The cleaning tape 2 on the take-up reel 4 side and the tape 2 outside the case are fed out from the cleaning tape 2 on the take-up reel 4 side and the tape 2 outside the case by utilizing the fact that the feed reel 3 is driven to rewind when the player performs a stop operation or after the end of the tape is detected.
In order to automatically rewind and store the cleaning tape 2, the total length of the cleaning tape 2 is set to 30 to 40 cm. If the tape material is thin, the total length of the cleaning tape 2 may reach several meters.
In this case, the tape 2 on the take-up reel 4 side is fed out and rewound onto the reel 3 side by operating the rewind button. Note that the lead tapes 2a and 2b may be opaque sheets with light passage holes formed therein. In order to alleviate the curling of the cleaning tape 2, the hub diameter of the feed reel 3 is set large.
The hub diameter of the take-up reel 4 is set to a very small diameter sufficient to wind up the cleaning tape 2. On the circumferential surface of the lower flange of the feed reel 3,
Engaging teeth 3a are formed, and the teeth 3a are closed when not in use.
A reel brake 7 that engages with the reel 3 to prevent free rotation of the reel 3 is provided facing the release pin hole 18, similar to the magnetic tape cartridge.

It is desirable to reduce the amount of tape drawn out during tape loading and to reduce the amount of relatively expensive cleaning tape 2 used. Therefore, the cleaning tape 2 is drawn out only from the central pocket 14 for tape loading.
In other words, the tape guides 10 and 11 are arranged to sandwich the pocket 14 on the left and right sides, and the tape guides 10 and 10 on the right side as viewed from the figure are arranged so that the cleaning tape 2 circumscribes the magnetic head H at a predetermined wrapping angle. , the tape guides 11 and 11 were arranged at a position sufficiently away from the right end of the pocket 14, and the other tape guide 11 was arranged near the pocket 15 for the capstan. Although the tape guides 10 and 11 shown in the figure are expected to be composed of freely rotatable rollers, they may be simply pin-shaped.

The feed reel 3 is located above the drive shaft insertion hole 19 on the right side and is rotatable, and has a hub hole into which the drive shaft engages, similar to the tape reel in a real magnetic tape cartridge. This payout reel 3
In particular, it has a function of rewinding and storing the cleaning tape 2 that has been pulled out of the case during tape loading.

The take-up reel 4 is disposed between the lamp hole 20 and the drive shaft insertion hole 19 on the left side, and is rotatably supported on the front end of a swing arm 23 supported horizontally on the bottom wall of the lower case 1b. do. The swinging arm 23 is urged to swing clockwise by a spring 24, and is held in a fixed position by a stopper 25 fixed to the lower case 1b. Gear teeth 26 are formed on the circumferential surface of the lower flange of the take-up reel 4, as shown in FIG.

A drive mechanism 5 is arranged between the take-up reel 4 and the capstan pocket 15. This drive mechanism 5 includes a pinch roller R (rotary drive body)
an input roller 28 that is circumscribed and receives power; a belt transmission mechanism that is rotationally driven by this roller 28;
The take-up reel 4 meshes with the gear teeth 26 mentioned above.
A gear 29 that drives the main swing lever 30, an auxiliary arm 31, and a pulley arm 32 that support each of these members.
Consists of etc.

The belt transmission mechanism includes a driving pulley 33, a driven pulley 34, and a rubber belt 3 wrapped around both pulleys.
It consists of 5. In FIG. 4, the input roller 28
A rubber ring 3 is attached to the upper circumferential surface of the driving pulley 33, which is circumscribed by
6 is fixed, so that the driving pulley 33 is rotationally driven by the pinch roller R via the input roller 28 without causing slip. Driven pulley 34
The gear 29 is integrally formed on the lower side of the body, and both rotate together. Both pulleys 33 and 34 are rotatably supported by a pair of upper and lower pulley arms 32 while always being separated by a certain distance. As shown in FIG. 5, the pulley arm 32 is supported so as to be able to swing relative to the auxiliary arm 31, and the lower arm 32 and the main swing lever 30
A spring 37 stretched between the lower case 1b and the spring arm 30a of the lower case 1b swings and urges the lower case 1b in a counterclockwise direction, and a guide roller 38 fixed to the lower case 1b holds the lower case 1b in a fixed position. At this time, the gear 29 is in a standby position away from the gear teeth 26 of the take-up reel 4, as shown in FIG. In order to engage the gear 29 with the gear teeth 26 by utilizing the movement of the pinch roller R into the pocket 15, that is, to switch the attitude of the belt transmission mechanism from the above-mentioned standby attitude to the transmission attitude, the lower pulley A cam surface 43 that circumscribes the guide roller 38 is protruded from the side edge of the arm 32.

The input roller 28 is rotatably supported by the main swing lever 30 while protruding into the pocket 15. The main swing lever 30 is rotatable around a pin 40, and is biased to swing so that the input roller 28 advances toward the outside of the pocket 15 by a spring 41 stretched between the left free end and the lower case 1b. and stopper 42
It is received at the swing limit position and regulated. In this way, the pinch roller R contacts the input roller 28 before contacting the capstan C.

In order to keep the rubber ring 36 of the driving pulley 33 in pressure contact with the input roller 28 at all times, the auxiliary arm 31 is swingably supported with respect to the main swing lever 30, and the auxiliary arm 31 is supported swingably between its left free end and the spring arm 30a. Spring 42 stretched over
The auxiliary arm 31 is urged to swing clockwise. As a result, the pulley arm 32 can swing relative to the auxiliary arm 31 and the main swing lever 30, and even if the posture is changed, both pulleys 33, 3
The pitch between the rubber belts 35 and 4 is always maintained constant, and the tension of the rubber belt 35 is maintained at an optimum level.

When not in use, the input roller 28 is provided at a position where it does not interfere with the capstan C and where interference with an auxiliary tape loading pin specially provided by the manufacturer can be avoided. This auxiliary loading pin is initially located within the entry area of the pinch roller R and further inside the case than the tape running surface of a real magnetic tape cartridge, and is linked to the entry movement of the pinch roller R into the pocket 15. The magnetic tape is provided for the purpose of swinging toward the outside of the pocket and maintaining the running posture of the magnetic tape vertically between the capstan C and the tape guide pin.

In FIG. 4, the input roller 28 is connected to a rubber ring 36.
It has a trunk shaft part 28a circumscribing the body shaft part 28a, and friction shaft parts 28b, 28b located above and below this. The friction shaft portion 28b is formed to have a slightly larger diameter than the trunk shaft portion 28a, and only this portion circumscribes the pinch roller R. Serration-like friction protrusions are formed on the circumferential surface of the friction shaft portion 28b as necessary. According to the input roller 28 configured in this way, the pinch roller R
The inside of the cartridge case 1 can be kept clean because microducts such as magnetic binders that adhere to the circumferential surface of the rubber ring 36 are not transferred to and adhere to the rubber ring 36.

In the figure, reference numeral 45 is a lamp for projecting light, A is a head for audio, L is a tape pull-out member, and 46 is a liquid supply port provided through the front lid 16 for supplying cleaning liquid.

Next, the operation of the head cleaner will be explained with a focus on the movement of the drive mechanism 5.

When the head cleaner is loaded into the player and the playback button is turned on, the tape pull-out member L is inserted into each of the tape loading pockets 13 and 14, and the capstan C is inserted into another pocket 15, and depending on the model, the auxiliary tape loading pin is inserted. enters each. Next, the front lid 16 is rotated upward, and the cleaning tape 2 is pulled out to the front of the case by the tape pull-out member L in the pocket 14 and pressed against the magnetic head H.

At the same time as this tape loading operation, the pinch roller R enters into the pocket 15. The pinch roller R advances to a position where it comes into pressure contact with the capstan C, but during this advancing operation, it comes into contact with the input roller 28 and swings the main swing lever 30 toward the inside of the case against the spring 41. . This causes the belt transmission mechanism to swing along with it. Due to this rocking, the pulley arm 32 tries to move inward of the case, but
Since the cam surface 43 is guided by the guide roller 38 in a receiving manner, the entire cam surface 43 moves inward of the case while swinging clockwise against the spring 37, and the gear 29 at the tip of the cam surface 43 takes up the winding. It gradually approaches the gear teeth 26 of the reel 4, and finally the gear 29 and the gear teeth 26 mesh with each other while the take-up reel 4 is slightly oscillated against the spring 24.

In this state, the pinch roller R is also in circumscribed contact with the capstan C and is driven to rotate. The rotational force is generated by the input roller 28, the rubber ring 36, the driving pulley 33, the rubber belt 35, the driven pulley 34, and the gear 2.
9 and gear teeth 26, and the take-up reel 4 is rotationally driven in the tape winding direction. The cleaning tape 2 now comes into sliding contact with the magnetic head H and the audio head A while running and cleaning the respective head surfaces. If cleaning liquid is injected from the supply port 44 in advance and impregnated into the cleaning tape 2, the cleaning tape 2 runs and performs dry cleaning after wet cleaning, thereby completely cleaning the head surface. I can do it. A few seconds after the start of tape feeding, the lead tape 2a on the feed reel 3 side crosses the optical path _P2 as shown in FIG. 3, allowing the detection light to pass through. This is the same state as when the end of the tape is detected in a real magnetic tape cartridge, the operation of each member on the player side is stopped, cleaning is completed, and the cleaning tape 2 is transferred to the feed reel 3.
is automatically rewound and stored.

At this time, the pinch roller R retreats to the outside of the pocket 15, and in conjunction with this, the main swing lever 30, belt transmission mechanism, etc. also move toward the front of the case, so that the meshing between the gear 29 and the gear teeth 26 is released. The take-up reel 4 can freely rotate and unwind the wound cleaning tape 2 without receiving any rotational resistance. Therefore, the cleaning tape 2 pulled out from the take-up reel 4 side and outside the case can be moved by using the player's original loading tape winding function and functions such as detecting the start or end of the tape. It has now become possible to automatically store it in the feed reel 3.

Embodiment 2 FIGS. 6 to 9 show a second embodiment of the present invention regarding the drive mechanism 5. FIG. In this example, the drive source of the drive mechanism 5 is a capstan C (driving rotating body).
This embodiment differs from the first embodiment in that the gear 29 is fixed and the take-up reel 4 side swings to engage the gear teeth 26 and the gear 29.

In this case, the rubber ring 36a is placed on the top of the driving pulley 33.
An input roller 28 into which is fitted is integrally formed,
These are swingably supported via the auxiliary arm 31 with respect to a base plate 49 that is swingable around the support shaft 48 of the driven pulley 34, and the base plate 49 and the auxiliary arm 31 are
The rubber belt 35 is swung and biased in the direction of tension by a spring 42 stretched between the belt and the belt. Further, a stopper 50 protruding from the lower surface of the base plate 49 receives and holds the auxiliary arm 31 at a prescribed position. This mechanism serves to keep the degree of pressure of the input roller 28 against the capstan C constant. The substrate 49 is urged to rotate counterclockwise by a spring 51 stretched between the substrate 49 and the case, and a pin 52 protruding from the lower surface of the substrate 49 is received and supported by the switching lever 30, so that the input roller 28 is held in a standby position located inward from the capstan pocket 15.

The switching lever 30 is equipped with a pilot roller 54, which is urged by a spring 41 so that it always protrudes into the pocket 15.
The operating arm 55 extending from the switching lever 30 moves the passive arm 56 extending from the swinging arm 23 to the spring 2.
By receiving and supporting the take-up reel 4 against the gear 29, the gear teeth of the take-up reel 4 are held in a standby position away from the gear 29. In other words, the board 49
The standby state of each member is maintained by the total tension of the spring 51 for the switch lever 23 and the spring 24 for the swing arm 23 being balanced with the tension of the spring 41 for the switching lever 30.

6 to 9, reference numeral 57 is a tape guide provided between the take-up reel 4 and the tape guide 11, 58 is a stopper for the board 49, and 59 is a hook 8 (not shown) that slips out of the case. This is a pin that prevents Note that members equivalent to those in Example 1 are given the same reference numerals.

When the pinch roller R enters the pocket 15, the drive mechanism 5 configured as described above switches from a standby state to an operating state in which the gear teeth 26 and the gear 29 are engaged, and the rotational power of the capstan C is transferred to the take-up reel 4. tell. In FIG. 9, when the pinch roller R reaches the specified position, the pilot roller 54 first comes into contact with the pinch roller R, and the switching lever 30 is swung clockwise against the spring 41. Then, the operating arm 5 of the lever 30
5 swings toward the front of the case and separates from the passive arm 56, the entire swinging arm 23 is pulled by the spring 24, and the gear teeth 26 of the take-up reel 4 are connected to the gear 29.
mesh with each other. At the same time, the pin 52 also moves following the switching lever 30, and the board 49 moves to the support shaft 48.
It swings in the tension direction of the spring 51 around . Then, the input roller 28 moves into the pocket 15 while moving along a swinging locus centered on the support shaft 48, and comes into contact with the capstan C. Therefore, the power of the capstan C is transmitted through the input roller 28, the driving pulley 33, the rubber belt 35, the driven pulley 34, and the gear 2.
9, gear teeth 26 and the take-up reel 4
will be rotated. At this time, a force is applied to the input roller 28 at the point where it contacts the capstan C in the direction of swinging the belt transmission system in the counterclockwise rotation direction, so that the power of the capstan C can be input without slipping or the like. This can be reliably transmitted to the roller 28.

The pilot roller 54 described above is provided at the same position as the input roller 28 in the first embodiment, and can also be used with players equipped with auxiliary loading pins specially provided by the manufacturer. It's summery.

In the head cleaner configured as described above, the input roller 28 is driven by the metal capstan C, so compared to the case where the rubber pinch roller R is used as the drive source, the peripheral surface of the pinch roller R may deteriorate or It is possible to effectively prevent magnetic powder and magnetic binder attached to the peripheral surface from entering the case. Furthermore, the feeding of the tape does not vary depending on the degree of deterioration of the rubber on the surface of the pinch roller R. Further, the base plate 49 and the swinging arm 23 are urged to the operating position by the spring 51 and the spring 24, respectively, and when changing the position of the drive mechanism 5, it is necessary to resist only the tension of the spring 41. This is advantageous in that the contact pressure of the pilot roller 54 can be reduced, and the load on the pinch roller R during use can be reduced.

[Another example]

The belt transmission mechanism in the above embodiments can be changed to a gear transmission mechanism using a group of gears, a chain transmission, or a transmission mechanism using a group of friction wheels. Since the drive mechanism 5 should be changed in various ways depending on the position of the take-up reel 4, the hub diameter, etc., its form is not particularly limited.

Tape loading may be changed so that the tape is pulled out from each pocket 13 and 14 at the same time, or only from the pocket 13 near the side end, as in the case of a magnetic tape cartridge.

In the illustrated example, a VHS video head cleaner has been described, but the present invention can also be applied to a Beta video player. In this case, if the lead tapes 2a and 2b are replaced with sensing tapes made of a base sheet laminated with aluminum foil, the end of the tape can be automatically detected in the same way as described in Example 1, and playback and rewinding can be performed. It is possible to automatically stop each mode. In addition to the above, the present invention can also be widely applied to audio players in which the magnetic tape is pulled out of the case.
