Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape deck for reproducing and / or recording / recording music and video data recorded on various magnetic tapes such as video tapes and cassette tapes. The present invention relates to a cleaning cartridge for a tape deck used for removing dust near a magnetic head, and a method for cleaning the inside of the tape deck.

[0002]

2. Description of the Related Art Conventionally, a tape deck has been used as a device for reproducing and / or recording / recording music and video data recorded on various magnetic tapes such as video tapes and cassette tapes. This tape deck is formed so that the information stored on the magnetic tape is read when the magnetic head contacts the magnetic tape. Therefore,
Foreign matter adheres to the magnetic head depending on the use situation or period, and the foreign matter becomes an obstacle when the magnetic tape reads data on the magnetic tape.

Therefore, conventionally, various cleaning tapes formed as cartridges have been used to remove foreign substances adhering to the magnetic head. This cleaning tape can be roughly classified into a wet cleaning tape using an organic solvent, and a dry cleaning tape that mechanically removes deposits.

[0004] Among them, a dry cleaning tape is one in which a polished surface of a magnetic head is slid on a surface to be cleaned of a magnetic head to forcibly remove foreign matters adhering to the head. For this reason, depending on the condition of use, there may be a case where the polishing becomes more than necessary, and when the slider is slid for a longer time than necessary, the head may be polished excessively.

On the other hand, the wet cleaning tape applies an organic solvent to a tape running in contact with a magnetic head, thereby cleaning the head. However, with this wet cleaning tape, running troubles such as sticking to the magnetic head during cleaning may occur,
Also, since an organic solvent must be injected during use, it is time-consuming to use. Further, handling of this organic solvent requires attention from the viewpoint of safety.

In the cleaning cartridge for a tape deck using the dry / wet cleaning tape provided so far, although it can be used repeatedly in practical use, strictly once it is used, Dirt and dust adhere to the tape. Therefore, from the viewpoint of sufficiently and safely cleaning the magnetic head, it is desirable not to use a portion used once in the tape.

Further, since the conventional cleaning cartridge has been developed exclusively for cleaning the magnetic head, it is not possible to remove dust adhering to its surroundings. However, it cannot be denied that dust existing near the magnetic head may eventually adhere to the magnetic head and have an adverse effect, or may have an adverse effect on other electric circuits accommodated in the tape deck. Therefore, in order to improve the durability of the tape deck, it is desirable not only to clean the magnetic head but also to remove dust that has entered the deck as much as possible.

[0008]

SUMMARY OF THE INVENTION The present invention solves the various problems of the above-described conventional cleaning cartridge, and does not adversely affect the magnetic head.
Provided is a cleaning tape that is easy to handle and use, and that can also remove dust near the magnetic head.

[0009]

SUMMARY OF THE INVENTION The present invention forms a cleaning cartridge for a tape deck, in particular, for charging a tape member with static electricity, thereby adsorbing and removing dust present in and around a magnetic head. . Thus, it is possible to avoid problems caused by polishing the magnetic head and running troubles such as sticking of the tape to the magnetic head during cleaning. In addition, since no organic solvent is used, handling and the like are easy. That is, the cleaning cartridge for a tape deck of the present invention is used for cleaning a magnetic head in a tape deck and / or its vicinity. A cleaning cartridge for a tape deck, wherein the cartridge is configured to include a tape member formed in a band shape using an insulating material including a resin material, and the tape member is formed as a member capable of charging static electricity. The magnetic head and / or dust around the magnetic head is attracted by the charged static electricity.

This tape member is formed so as to be chargeable and to adsorb dust by the charged static electricity. Therefore, the material constituting the tape member needs to be selected so that static electricity can be charged,
Further, the cleaning cartridge needs to be configured so that the tape member charges the static electricity.

According to the cleaning cartridge for a tape deck, a method of cleaning the inside of the tape deck by adsorbing dust in the magnetic head and its vicinity by the charged static electricity according to the present invention is realized.

That is, a method of cleaning a magnetic head for reading information recorded on a magnetic tape and / or a tape deck for removing dust near the magnetic head, wherein a tape member formed in a strip shape using an insulating material is provided. A cleaning method in a tape deck, wherein static electricity is charged, and the tape member attracts a magnetic head and / or dust near the magnetic head by the charged static electricity. As the tape member adsorbs dust, the magnetic head in the tape deck and / or dust existing near the magnetic head is removed.

The cleaning cartridge described above is formed in the same shape and size as various tape cartridges for reproduction and / or recording which are standardized and provided for each tape deck. In most cases, the shape and size of the cleaning cartridge are embodied by the shape and size of the housing that houses the tape member. That is, for example, in a cleaning cartridge used for a tape deck for reproducing an audio tape, the cleaning cartridge is formed in the same shape and size as a conventionally provided audio tape, and the sound is recorded and reproduced in a digital format. A cleaning cartridge used for a tape deck for reproducing a digital audio tape (DAT) is formed in the same shape and size as a conventionally provided digital audio tape (DAT). Further, a cleaning cartridge used for a tape deck for reproducing a video tape capable of recording video data in addition to audio data is formed in the same shape and size as a conventionally provided video tape.

As described above, by making the cleaning cartridge of the present invention the same shape and size as the tape cartridges standardized and provided for each tape deck, normal reproduction and reproduction can be performed in each tape deck. With the same operation as the recording operation, dust in and around the magnetic head can be removed. That is, when a normal reproduction or recording operation is performed with the cleaning cartridge mounted, static electricity is charged to the tape portion of the cleaning cartridge, and the tape portion adsorbs the magnetic head and dust near the magnetic head. Then, if the adsorbed dust is removed by a method described later or the like, the inside of the tape deck is cleaned.

In the cleaning cartridge of the present invention,
The tape portion that is driven in the tape deck and that actually absorbs dust is formed in a belt shape using an insulating material including a resin material. In the concept of the present invention, since this tape portion absorbs dust by charging static electricity, it is desirable that the tape portion is formed so as to be more easily charged with static electricity. For example, this tape member
It is formed in a belt shape using a resin material, and desirably does not contain an antistatic agent and is formed without performing an antistatic treatment. More specifically, this tape member is also realized by, for example, forming a belt-like shape using a resin composition in which a plasticizer, a heat stabilizer, and the like are added to a resin component such as polyethylene terephthalate (PET). be able to. However, even if the antistatic agent is added to the resin material, the tape member can be formed using the antistatic agent as long as the amount of the antistatic agent can maintain the charged static electricity. The reason for allowing the addition of the antistatic agent is as follows.
This is because there is a possibility that it may be necessary to add Dust in order to avoid attachment of dust during the production.
Antistatic materials that can be added without departing from the spirit of the present invention include distearylhydroxylamine, triphenylamine, tri-n-octylphosphine oxide, triphenylphosphine oxide, pyridine N-oxide, ethoxylated Conventionally used antistatic materials such as sorbitan monolaurate are widely used.

The tape member made of the insulating material such as the above resin material may be further provided with a magnetic layer, if necessary, to record information such as music, image data or various programs. In this case, for example, if music data is stored in the magnetic layer, the cleaning of the tape deck can be performed while playing back music and sounds such as precautions for use.

The structure in which the tape member included in the cleaning cartridge is charged by driving in the tape deck may be, for example, a structure in which a contact member made of an insulating material that comes into contact with the tape member when the tape member is driven. It can be. That is, the cleaning cartridge for the tape deck is configured to also include a contact member made of an insulating material, and the contact member is moved from the supply reel to the take-up reel in the vicinity of the supply reel around which the tape member is wound. A cleaning cartridge for a tape deck is disposed in contact with the tape member toward the tape deck. Thus, the take-up reel winds the tape member from the supply reel, and rubs against the contact member made of another insulating material, so that the tape member can be charged with static electricity. This contact member is desirably detachably attached to the housing. This housing is desirably formed in a shape and size standardized for each tape deck to be used. By making the contact member detachable, even if the contact member is deteriorated by use, it can be easily replaced. By arranging the contact member as a member that comes into contact with the cleaning surface of the tape member that contacts the magnetic head, even if dust adheres to the tape member through multiple uses, the magnetic head Before heading for cleaning, dust adhering to the tape member can be removed.
Even in this case, if the contact member is detachably arranged, the contact member from which dust has been removed from the tape member can be easily replaced or cleaned. Further, if the contact member is arranged so as to be in contact with the tape member returning from the take-up reel to the supply reel, dust adhered to the tape member is removed at the stage of unwinding the wound tape member. be able to. In particular, when the tape is rewound without contacting the magnetic head, the tape member that has absorbed the dust and is wound on the take-up reel can be removed by a rewind operation. It can be used repeatedly. Conventionally, in a video deck or the like that is commercially available for reproducing video tapes, the tape (tape member) is rewound without contacting the magnetic head. The dust adhering to the tape member can be cleaned without giving.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A cleaning cartridge for a tape deck according to the present invention will be described below with reference to the drawings. Embodiment 1 FIG. 1 is a schematic rear perspective view showing an embodiment of a cleaning cartridge 1 for a tape deck of the present invention. The cleaning cartridge 1 for a tape deck shown in FIG. 1 (hereinafter referred to as "cleaning cartridge 1") is a cleaning cartridge 1 for a video deck used especially for playing / recording a video tape. In the cleaning cartridge 1 for a video deck, a supply reel 3 and a take-up reel 4 are arranged in a rectangular casing 2, and a belt-shaped tape member 5 is further attached.
It is wound around the supply reel 3 and / or the take-up reel 4 and arranged. A contact material 6 made of an insulating material is arranged on the supply reel 3 side so as to contact the tape member 5 facing the take-up roll 4. In the cleaning cartridge 1, the width of the tape member 5, the position and size of each reel, and the like, including the housing 2, are adjusted in the same manner as a conventionally standardized video tape cassette provided. Therefore, this cleaning cartridge 1
Can be loaded into a video deck without any difference from a video tape cassette for recording / playback.

In this embodiment, the tape member 5
Is formed in a belt shape using a resin composition in which a plasticizer, a heat stabilizer, and the like are added to a resin component such as polyethylene terephthalate (PET). In the cleaning cartridge 1 shown in this embodiment, from the viewpoint of manufacturing cost
The tape member 5 is formed without a magnetic layer for recording video and audio data and the like. However, if video and audio data can be reproduced without any problem in view of the static electricity charged on the tape member 5, various parts of the tape member 5 that come into contact with the magnetic head 7 are The magnetic layer can be provided by using a technique known in the field of manufacturing a magnetic tape. In addition, even if there is a problem in reproducing the video and audio data recorded on the magnetic layer, if no special video or audio data is recorded or reproduced on this magnetic layer, the tape provided with the magnetic layer The member 5 can also be used. However, since the idea of the present invention is to adsorb dust by static electricity, the condition is that the tape member 5 used in the cleaning cartridge 1 can be charged with at least static electricity enough to adsorb dust. .

The contact material 6 arranged on the side of the supply reel 3 in the housing 2 and in contact with the tape member 5 toward the take-up roll 4 includes a resin material such as polyethylene or polypropylene. Are formed using various insulating materials. In the present embodiment, the contact material 6
Is formed in a pad shape and is in surface contact with the tape member 5 from the supply reel 3 toward the magnetic head 7. Naturally, the contact material 6 can be formed into various shapes including a columnar shape, and a plurality of contact members can be provided. Further, the contact members may be arranged to face each other, and the tape member 5 may be held between the two contact members.

When the cleaning cartridge 1 is mounted in a video deck and the same operation as recording / reproduction is performed, the tape member 5 is guided by the guide post, comes into contact with the magnetic head 7, and takes up the take-up reel. 4 winds the tape member 5 wound on the supply reel 3 as needed. The tape member 5 heading from the supply reel 3 to the take-up reel 4 is in contact with the contact member disposed immediately above the supply reel 3, so that the tape member 5 is taken up by the take-up reel 4. As a result, the tape member 5 charged with static electricity passes through the inside of the video deck, so that dust ubiquitous in the vicinity thereof can be adsorbed. Thereby, not only the magnetic head 7 but also dust existing near the tape member 5 passing portion in the video deck can be removed. Therefore, also in this respect, it can be clearly distinguished from the wet or dry cleaning tapes conventionally provided.

Then, the cleaning cartridge 1
When the tape member 5 is wound on the take-up reel 4 once, that is, when all of the tape members 5 have been used for cleaning the VCR at least once, the tape member 5 is wound on the take-up reel 4. The tape member 5 is rewound toward the supply reel 3 in the video deck. Since the tape member 5 to be rewound on the supply reel 3 has already adsorbed dust in the video deck, dust is naturally adhered to the front / rear surfaces of the tape member 5, and the dust directly contacts the magnetic head 7. In such a case, the inside of the VCR is contaminated. However, the conventional VCR has a structure in which, when the tape member 5 is rewound,
Since the tape member 5 is carried out without contacting the magnetic head 7, contamination by the rewound tape member 5 does not pose a problem.

The tape member 5 to which the dust has adhered is
Before being wound back on the supply reel 3, the contact member comes into contact with the contact member. Since the contact member is detachably disposed, the tape member 5 can be used again if it is taken out after being rewound and cleaned. The contact member taken out can be replaced with a new one. The structure that makes the contact member detachable
For example, it can be realized by a structure or the like in which this contact member is fitted into the housing 2 of the cleaning cartridge 1 for the tape deck.

[0024]

The cleaning cartridge for a tape deck of the present invention is formed so that the tape member is charged with static electricity, thereby adsorbing dust in the tape deck. Therefore, not only the magnetic head but also dust ubiquitous in the vicinity thereof can be adsorbed, and efficient cleaning in the tape deck is realized.

This cleaning cartridge is
Since dust is adsorbed by static electricity, the magnetic head is not polished unlike a conventional dry cleaning tape, and there is no possibility that the magnetic head is adversely affected. Further, since no organic solvent is used, its use and handling are easy.

In particular, when a contact member that contacts the tape member from the supply reel toward the magnetic head is disposed, the contact member cleans the tape member when supplying and / or winding the tape member. Even when used repeatedly, there is no possibility that the magnetic head will be adversely affected.
