A cartridge (45) is fixedly secured to a rotary plate (34) and a plastic plate by nuts and bolts (41), (41) at a head shell (6) of the end of a tone arm. The rotary plate (34) is rotatably mounted around a rotary mounting shaft (32) disposed at the rear of a stylus (30). A guide piece is provided at the end of the plastic plate to introduce the stylus of the cartridge (45). There is formed a hole through which the semi-circular hole of a song selection plate (1) additionally prepared and capable of being engaged with the spindle at the center of a turntable is superimposed with the central hole (29) of a spindle push plate. A dimorphic tape (20) is attached on each of the front and the rear sides of the plate (1) to extend from the center of the hole rectilinearly toward the radial line of a record disk. A stopper made of a small piece of the dimorphic tape for indicating the central point of the lead-in of each of the songs on the record disk is adhered onto the tape (20). The guide piece is brought into contact with the stopper to introduce the stylus (30) along the sound groove of the desired lead-in on the record disk.

Description

Ming Gramophone with improved tonearm structure and special selection plate for record head cueing device

When playing a conventional record on a conventional record player, it is impossible to move the needle to the desired position on the record. In other words, in order to provide a random access function, the record player has a music selection aid and the head shell at the tip of the torn arm has a specially structured cartridge. This can be achieved by providing a support device. Back of technology

Audience lovers nowadays can easily and freely select the songs or scenes they like on the alpam record or the opera record. I hope that this can be done with the model being used. Since the-flops over ya style of hand-held is spent through a shake down invention of Na over the disk (1 ⁸ 9 0) since about one hundred years have been ¾ is many of the improvement invention. Only one undeveloped part has been left. In other words, this technology exerts the function of rejecting the sound needle attached to the headshell of the torn arm at the desired location of the spiral line recorded on the disk. A number of patents have been registered at home and abroad, but their concerns have been resolved.

O PI _., Vv'iPO " Not.

Models appearing on the market with random access functions use infrared and laser light. In the former case, silence of the lead-in is absolutely necessary. Therefore, the extremely short or non-silent Nan-stop record or operator of the silence groove of the lead-in which has recently emerged in West Germany

Cannot be used for records. One of the video desks using the laser beam (Filip-type) has 54,000 bits for 30 slabs.? In the case of 180 OZ rotation, it is 100 times the rotation. The random access function is possible because it rotates to find the desired location in a short time. However, currently there are three types of video discs, but all the records (referred to as software), like a record board, do not fit all players, so there is a problem with software. The difficulty is that only 200 kinds of software have been marketed in the United States in the two years since its launch. It must be said that it is difficult to have as many libraries as in conventional records. In the case of using this laser beam, the screen is clearer than v, TR, but there is a drawback that noise is generated.

In the case of Honkiaki, the mechanism around the cartridge that makes the selection plate and special structure work! ? Achieve random access functions using an ordinary player. A stopper is attached to the music selection plate at a desired position on the record in order to guide the sound needle guide piece attached to the cartridge.

UK hi τιθ For a record that has already left the record factory, the stocker that is mounted on the substrate of the curved plate is an audiophile because it can be easily mounted by the owner's hand. The vast library of records owned by the company will immediately benefit from the invention, and new records to be released in the future will have a stamper with a built-in stopper. It will be mass-produced and released along with the record.

In the invention claimed in Japanese Patent Publication Publication No. 42-104545, the head shell is applied vertically at the point of the sound needle in order to eliminate the tracking error. -Attaching the bolt with a bolt, or allowing the bolt to freely rotate around the center axis, and connecting the record to the end of the head shell. A brush or the like is installed to rotate by the frictional force to eliminate the tracking error. In the present invention, the force grid is fixed, so that the sound needle is rejected to a desired point, and the operation is completely different from the purpose, and in order to facilitate the adjustment in the present invention. The mounting bolt should be mounted eccentrically at the middle of the sound needle, not in the vertical position above the sound needle, but in the direction of the three-tone arm.]? Freely move the landing point of the record in the radial direction of the record to determine the difference between the gap between the grooves on the front and back of the record, and the difference in the expansion or contraction of the selection plate and the record by the degree D The resulting error can be adjusted appropriately. Disclosure of the invention

Aegisson and Brenner are the developers of the most widely used phonograph hard and software today. More specifically, two different center elements, a torn arm and a turn table, consist of a cooperative operation achieved in a circular motion. The purpose was achieved in the first place, and the prosperity of today is seen 100 years later. Advances in the use of electronics have further increased the coordination of hardware and software: ¾wa ?? Now the function of random access is a challenge for the development of phonographs. In the past, hard technicians and soft technicians may have developed from their own standpoint. From the standpoint of phonograph users, what we want is that the most widely used phonographs at present can exhibit random access functions. The first is that the software format represented by the record is the most constructive and interchangeable. Regardless of who plays the record, it can be easily played back on a player who is a general hand-held hardware. No one can disagree that this form of uniformity has caused the rise of the current record, and how important it was later developed.

The VTR is experiencing the difficulties arising from the existence of the two forms. More notably, in the case of video discs, the three forms are likely to arise from different physical starting points. The problem is becoming more complicated by the future in the future because of the lack of compatibility. When you think about it,

Ο Η

Λ ,. n-6 ~ " What is the future potential of VIDEO? VTRs and video discs do not.]? However, today's development of electronic use has made it easier to provide the function of Lander's 4 access to VTRs and video disks, while the number of records has increased by more than 100 years. They are unsuccessful despite their efforts. The present invention focuses on this point, and is applicable to all models.

The access mechanism was successful. Therefore, as a result, the future potential of the record was further expanded.I) The importance of the generality of the record was important for this success without any fear from VTRs and video discs. And it must be more noticeable to video disc makers.

The random access mechanism of the present invention is a cartridge mounted on a head shell at the tip of a torn arm generated from a rotating shaft of the torn arm. The position of the sound needle on the record provided on the surface of the music selection plate with reference to the center of the turntable and the guide tip of the turntable corresponding to it. It is from a guiding piece that has a stocker indicating the point of fall. In the case of a general record, there is a silent silence between each of the recorded small pieces, so the preferred fall point of the needle is aimed at the middle point. . In the case of opera or non-stop records, the preferred drop point is one end of the stopper immediately before the desired song or scene. The leading end of the sound needle, which is different from the rotation axis of the tone arm, and the sound needle are directly above. This is a staggered plate. One with

Since the torn arm and the turntable are mechanically integrated for a moment by contact, the accuracy can be said to be high. Music selection plate its materials to require precise thermal expansion coefficient Using enhanced re es ether containing the glass锇維at ^{8 X 1 0- 5 cm / cm} / C. This is one-eighth of ordinary PVC.

The cartridge attached to the head shell on the ton arm side is likely to be rotatable with the bolt attached to the head shell via a tilling plate. The axis of the bolt is also the vertical line of the needle.]? It is displaced toward the root of the torn arm by retreating to 3. Its purpose is to rotate] as the position of the sound needle approaches in relation to the central axis of the table. The guide tip, which is a straight line with the sound needle, is attached to the cartridge and to the rotating plate at the position specified by international standards with a bolt nut located at the rear of the guide plate. The rear tail of the rotating plate serves as an indicator, and the check window at the rear of the living head shell confirms the situation when the rotating plate puts the sound needle of the cartridge in the optimal position. You can do it. Conventionally, the torn arm is folded in two

It gives the cartridge an offset angle to mitigate the tendency of the torn arm to skew toward the central axis as it approaches the central axis of the turntable. ) An antiscaling correction mechanism is provided. If there is a skew, it is difficult to be accurate when it falls on the sound needle record.

3 this ϋ ί--Fl In the present invention, by rotating the cartridge, the torn arm is substantially bent three times so as to prevent such a tendency and accurately record both the outer side and the inner side of the record. Just follow the stopper on the selection board on the code so that it falls exactly. Therefore, an unnecessary anti-scaling mechanism is unnecessary.

According to the invention of the present application, an unfinished (Preiormer, FIG. 2) return plate prepared by the owner and prepared by the owner is easily processed with a little skill for the existing record by the above method. Completion (Fig. 4) Yes, but in the future, record producers will be able to mass-produce the selected selection plate as a mother with a stamper and sell it along with the record. The headshell is provided by the player producer and is marketed along with the player. Brief explanation of drawings

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in detail with reference to the accompanying drawings in order to describe it in detail. '

See Figure 1 at the end.

Radiating from the center of the center spindle hole of the record

A two-sided line with an angle of 10 shin is set on both sides. A 0.7 mm thick glass steel plate is selected. 10 Abrasion Dymotape is adhered by removing the backing pieces on both sides, one on each side.

Equipped with a head shell 6 at the tip of the torn arm 5 to which the bent plate 1 and the sound needle indicator 10 of the present invention are attached.

The figure shows the Elector / Servo / Player / System QL-type player from Japan Victor (JVC), which was released at the end of 1979. In particular, it was not enough to select this model even if it reached the highest limit of electronic technology, and the random access function (search function) became a breaker for the first time using the present invention. This is to clarify what will be provided. Tone arm 5 is a lead-in switch 15 and a lead-out switch 16 of its arm operation mechanism (up-down switch). 1 7!]? Record surface is white

OMPI IPO Although it can be moved up and down for any reason, it has a precise function to move the sound needle to the desired position. The optical sound (video dusk) player can search a large number of bits, so that the random access function is fully demonstrated. The fact that the player has the random access lateral ability will probably marry the future as an audio device. The above-mentioned defect can be compensated for by the two elements of the present invention, namely, the selection plate and the eccentric rotary force-trigger.

尙, front oh. Other than the above, the power switch 12, turn-on / start-up switch 13, reject switch 14 and up-down switch 17 are provided.

At the center of the player's center spindle, a level 4 is mounted on a return baffle 1 to maintain the level of the baffle and hold down during operation.

See FIG. The first step of the selection plate is shown.

The selection plate 1 is a glass plate that is reinforced with a glass cone known as FILON (registered trademark) having a thickness of 0.7 millimeters. This is because the board is one-eighth of the ordinary polyvinyl chloride board in terms of the degree of stretching. Since the flatness of the commercially available fiber fins is insufficient, the plywood form is formed by attaching a 10-millimeter die tape 20 on both sides to obtain the required flatness. . Double layer dymotape 20 length approx. 170 mm Milli lining]? The end is glued to the contact point 24 of the center vial hole 23 and the other end is glued to the other end 27 of the selection plate 1 in the diagonal direction. Leads on album record

There is a silence groove 2 to distinguish each music, but the middle point ^{3 /} is connected. Use the tip of the needle to transfer the tape to the die tape with a pinhole (· ■ ················· 3 ′). Two small holes 13 are provided adjacent to and separated from the central binder hole 23.

The present invention relates to a spinning cartridge mounting structure that forms a core together with the music selection plate of the present invention. In the PCT / JP 79/2000/26, the cartridge rotating plate 2 of the head shell 22 is placed on the vertical line of the sound needle 30. Although the mounting hole 2 S for the mounting shaft 4 and the shaft 25 is provided, even if it rotates, the relative distance between the sound needle 30 and the center spindle 3 of the record will change.

In the present invention, the mounting shaft 35 of the rotating plate 34 is the sound needle 30]. 3 mm. ) Sound needle

10 mm Retreating. In the center of the rear end of the rotating plate 34, a meter reading 38 is formed, and the angle of rotation can be known from the side window 37 provided in the head shell 6).

The sound needle guiding piece 39 is positioned so that its position can be changed to the plastic guiding piece 40, and then the cartridge is different from the cartridge rotating tip in the case of the needle. The hole to which the bolt 1 to be connected is attached is 4 ^.菽; 3 応; By changing the position of the sound needle 30 by the same rotation, the sound needle can be accurately displaced from the inner groove as well as the outer groove of the record board. Conventional cartridge mounting is usually fixed to the head shell, and the ton arm is normally folded in two.]? The tracking error angle is kept at a small value with the overhang, but this is not enough, so that the inside force is generated toward the center. For this reason, the random access mechanism is useless because it moves at the point of fall even if the fall position of the bevel is predetermined. In the present invention, the center line connecting the sound needle and the sound needle guiding piece 39 is formed by the above-described eccentric mechanism. 1—The exact random access mechanism was completed.

See FIG.

The above-mentioned selection plate is a processing method for a record board that has already left the manufacturer's hand, but it is preferable that the record plate manufacturer prepares the selection plate together with the record plate. It is to be. The music selection plate GD shown in Fig. 7 can be made with a mother and a stan and ー. And handle ₄ 3 is a stopper

Therefore, it is necessary to prepare a selection plate corresponding to each record board. However, the manufacturing cost of the external standard handle, which improves the accuracy, can be omitted, and the economic burden is reduced.

The tape used for the U.S.-made daimo (DYM0) is only used for this kikimi, and the daimo itself is not required. A Belgian Deca Dry (DSCARY) is used to indicate the position of the marking strip.
