1276051 五、發明說明（1) 【發明所屬之技術領域】本發明有關一種碟機進退片方式，尤其關於吸入式碟機用以判別碟片尺寸，以及篩選適用碟片的方法及裝置。【先前技術】1276051 V. INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field The present invention relates to a disc drive advance and retract mode, and more particularly to a method and apparatus for discriminating a disc size and screening a suitable disc for a slot type disc player. [Prior Art]

由於碟片主要分為8c m及1 2 c m兩種尺寸，習知碟機為了滿足消費者的方便，一般均設計同時可適用這兩種尺寸的進退片機構。如圖1所示，以習知吸入式碟機1 0為例，該吸入式碟機1 0於入口 1 1處設一圓錐條狀的滾淪1 2，近滾涂1 2前後各設一感測器1 3 a及1 3 b，藉感測器1 3 a感應碟片 1 4***時，立即正向轉動滾淪1 2將***的碟片1 4吸進碟機 1 0，並利用接片桿1 5對稱的定心柱1 5 a及1 5 b承接碟片1 4的一端周緣，使碟片1 4的中心自動對正主軸馬達1 6的中心線，然後在滾輪1 2驅動下’接片桿1 5以定心鎖定心柱1 5 a 及1 5b順著平行滑槽1 7a及1 7b滑動，輸送碟片1 4的中心到達主軸馬達1 6，使主軸馬達1 6轉動碟片14，以完成定位。此外，退片時則反向轉動滾淪1 2，使碟片1 4退出碟機1 0，當碟片1 4脫離感測器1 3 b時，即停止滾輪1 2轉動，讓碟片 1 4銜於入口 1 1，等待取走。因碟片1 4的尺寸不同，碟片1 4中心的位置就會改變，接片桿1 5的移動距離就需配合改變，否則會壓毁未定位的碟片1 4。因此，習知碟機1 0在側邊設置一選片桿1 8，並在後側設一選擇性連動的啟動臂1 9，作為判別碟片的機構。當8cm的碟片14a進片時，因尺寸較小，不會觸及選片桿Since the disc is mainly divided into two sizes of 8c m and 1 2 c m, the conventional disc player is designed to meet the convenience of the consumer, and is generally designed to be applicable to both the advance and retractable mechanism of the two sizes. As shown in FIG. 1 , a conventional slot-type disc player 10 is taken as an example. The slot-in disc drive 10 has a conical strip-shaped roller 12 at the inlet 1 1 and a front-to-roll coating 1 2 The sensors 1 3 a and 1 3 b, by the sensor 1 3 a, the sensing disc 1 4 is inserted, immediately rotates the roller 1 2 and sucks the inserted disc 1 4 into the disc player 10, and utilizes The stator rods 1 5 symmetrical centering rods 1 5 a and 1 5 b receive the circumference of one end of the disc 1 4 so that the center of the disc 14 is automatically aligned with the center line of the spindle motor 16 and then driven by the roller 12 The lower 'tab lever 15 is slid with the centering locking stems 5 5 a and 15 b along the parallel chutes 1 7a and 17b, and the center of the transporting disc 14 reaches the spindle motor 16 to rotate the spindle motor 16 Disc 14 to complete the positioning. In addition, when the film is unloaded, the roll 1 2 is reversely rotated, so that the disk 1 4 is ejected from the disk drive 1 0. When the disk 1 4 is disengaged from the sensor 1 3 b, the rotation of the roller 12 is stopped, so that the disk 1 is rotated. 4 at the entrance 1 1, waiting to be taken. Due to the different sizes of the discs 14, the position of the center of the discs 14 will change, and the moving distance of the tabs 15 will need to be changed, otherwise the undisposed discs 14 will be crushed. Therefore, the conventional disc player 10 is provided with a selector lever 1 8 on the side and a selectively interlocking actuator arm 9 9 on the rear side as a mechanism for discriminating the disc. When the 8cm disc 14a is fed, it will not touch the selector lever due to its small size.

第6頁 1276051 五、發明說明（2) .1 8，啟動臂1 9將維持在原來的位置。由接片桿1 5在輸送碟片1 4中，以突銷1 5c於啟動臂1 9的條槽1 9a中滑動，且順著 > 滑槽1 7c移動，帶動啟動臂1 9以嵌置於移動槽1 0 1的支軸 1 9 b為中心轉動，使啟動臂1 9上的限位銷1 9 c，沿著凸輪槽 1 0 2的小槽邊1 0 2 a移動，同時限制接片桿1 5移動較小的距離，讓8 c m的碟片1 4 a移動至定位。如圖2所示，當1 2cm的碟片1 4b進片時，因較大的直徑 p撥動選片桿1 8的前端部1 8a，選片桿1 8以支點1 8b為中心轉動，使1 8的後端部1 8 c推動啟動臂1 9，讓支軸1 9 b沿著移動槽1 0 1往内移動，同時讓限位銷1 9 c進入凸輪槽1 0 2的大槽中。再由接片桿1 5在輸送碟片1 4b中，以突銷1 5c於啟動臂 1 9的條槽1 9 a中滑動，且順著滑槽1 7 c移動，帶動啟動臂1 9 .以支軸1 9 b為中心轉動，使限位銷1 9 c沿著凸輪槽1 0 2的大槽邊1 0 2 b移動，令接片桿1 5可移動較長的距離，而使1 2 c m •的碟片1 4 b移動至定位。然而，習知碟機1 0使用多桿件的機構判別碟片的尺寸，雖可使8cm及12cm的碟片完成進退片的動作，但置於入口 1 1的選片桿1 8，前端部1 8a易於被偏離***的8cm碟片 ®碰觸，導致誤動作而損壞碟片。同時多桿件的機構需要足夠的堆疊高度，不僅造成碟片的厚度無法薄化，況且多桿件的零件過多，管理及成本高，製造組裝複雜費時。因此，習知碟片裝置的聚焦調整方法仍有問題存在，有待決解決。Page 6 1276051 V. INSTRUCTIONS (2) .1 8. The starting arm 19 will remain in its original position. The ejector lever 15 is slid in the transporting disc 14 by the ejector pin 15 and the spur pin 15c is slid in the slot 19a of the actuating arm 19, and is moved along the > chute 1 7c to drive the actuating arm 19 to be embedded. The support shaft 1 9 b placed in the moving groove 1 0 1 is rotated centrally, so that the limit pin 1 9 c on the actuating arm 19 moves along the small groove side 1 0 2 a of the cam groove 1 0 2 while limiting The slider 1 5 moves a small distance to move the 8 cm disc 1 4 a to position. As shown in FIG. 2, when the 12 cm disc 14b is fed, the front end portion 18a of the selector lever 18 is dialed by the larger diameter p, and the selector lever 18 is rotated about the pivot point 18b. The rear end portion 18c of the 18 is pushed by the starting arm 19, and the support shaft 1 9b is moved inward along the moving groove 110, while the limit pin 1 9c is inserted into the large groove of the cam groove 1 0 2 in. Then, the ejector lever 15 is slid in the transporting disc 14b with the protruding pin 15c in the slot 19a of the starting arm 19, and moves along the chute 1 7c to drive the starting arm 19 . Rotating around the fulcrum 1 9 b causes the limit pin 1 9 c to move along the large groove side 1 0 2 b of the cam groove 1 0 2, so that the splicing rod 15 can be moved a long distance, and 1 2 cm • Disc 1 4 b moves to position. However, the conventional disc player 10 uses a multi-bar mechanism to discriminate the size of the disc, and although the discs of 8 cm and 12 cm can be moved forward and backward, the selector lever 1 8 of the inlet 11 is placed at the front end. 1 8a is easily touched by the 8cm disc® that is offset from the insertion, causing malfunction and damage to the disc. At the same time, the multi-bar mechanism requires a sufficient stacking height, which not only causes the thickness of the disc to be thinned, but also has many parts of the multi-bar, high management and cost, and is complicated and time-consuming to manufacture and assemble. Therefore, there is still a problem in the focus adjustment method of the conventional disc device, which is yet to be resolved.

Wait. Wherein, the roller 2 1 is horizontally disposed at the entrance 2 of the disc drive 20, and the sensing unit 2 2 can be a sensor such as a photosensitive type or a limit switch, and the plurality of sensors 2 2 1 , 2 2 2 2 3 and 2 2 4 are formed, and the adjacent roller 2 1 is arranged in a row in the inlet 2 6 . The embodiment is illustrated as an example of the rear of the roller 2 1 , and the sensing unit 2 2 can be activated according to the detection result. Or stop the roller 2 1 to rotate.

此外，主軸馬達2 3則設於碟機2 0近中心處，接片桿2 4 鄰近主轴馬達2 3的後方，接片桿2 4兩端各設一對稱主軸馬達2 3的定心柱2 4 1，中間設一限位銷2 4 2，碟機2 0在主軸馬達2 3後方沿碟片2 7進退片方向，平行設置三條狀滑槽2 8，讓兩定心柱2 4 1及限位銷2 4 2在三條狀滑槽2 8内滑動，使接片桿2 4可沿碟片2 7進退片方向移動。限位單元2 5則臨設於限位銷2 4 2滑動的滑槽2 8邊，依感測單元2 2判別碟片尺寸In addition, the spindle motor 23 is disposed near the center of the disc drive 20, the tab 2 4 is adjacent to the rear of the spindle motor 23, and the centering rod 2 of the symmetrical spindle motor 2 3 is disposed at each end of the tab 2 4 1, a limit pin 2 4 2 is set in the middle, the disc drive 20 is in the direction of the retraction of the disc 2 in the rear of the spindle motor 2 3 , and three strip chutes 2 8 are arranged in parallel, so that the two centering rods 2 4 1 and The limit pin 2 4 2 slides in the three-shaped chute 28 to move the tab 2 4 in the direction of the disc 27 in the ejecting direction.

第9頁 1276051 五、發明說明（5) 的結果，選擇性以限位塊2 5 1限制接片桿2 4移動的距離。Page 9 1276051 5. As a result of the invention description (5), the limit of the distance the slider 2 4 moves is selectively limited by the limit block 2 5 1 .

因此，碟機2 0可由感測單元2 1偵測碟片2 7的***及尺寸，轉動滾輪2 2吸入碟片2 7，及選定配合的限位單元2 5限位塊2 5 1，接片桿2 4的定心柱2 4 1承接碟片2 7的後端圓周， •使碟片27自動對正主軸馬達23的中心線，在滑槽28的引導下，接片桿24後移至限位單元25限制的距離，使碟片27到達主軸馬達2 3完成定位。當退片時，則反向轉動滾輪2 2送出碟片2 7，至感測器2 2 1、2 2 2、2 2 3及2 2 4動作數目減少至預定數時，停止滾輪2 2轉動，讓碟片2 7銜於入口 2 6，等待取走。本發明之碟片判別裝置，藉由感測單元判別碟片的尺寸，取代習知多桿件的判別碟片的機構，避免長桿件動作的空間及堆疊高度，可有效使碟機薄化，節省製造成本，及提高組裝效率。Therefore, the disc drive 20 can detect the insertion and size of the disc 27 by the sensing unit 2 1 , the rotating roller 2 2 sucks the disc 2 7 , and the selected matching unit 2 5 the limit block 2 5 1 The centering rod 2 4 1 of the film rod 2 4 receives the rear end circumference of the disc 27, • causes the disc 27 to automatically align the center line of the spindle motor 23, and under the guidance of the chute 28, the rod 24 is moved backward The distance limited to the limit unit 25 causes the disc 27 to reach the spindle motor 23 to complete the positioning. When the film is unloaded, the roller 2 2 is reversely rotated to send the disk 2, and when the number of actions of the sensors 2 2 1 , 2 2 2, 2 2 3 and 2 2 4 is reduced to a predetermined number, the rotation of the roller 2 2 is stopped. Let the disc 2 7 be attached to the entrance 2 6, waiting to be taken away. The disc discriminating device of the present invention discriminates the size of the disc by the sensing unit, and replaces the mechanism for discriminating the disc of the conventional multi-bar member, thereby avoiding the space and stacking height of the long rod movement, and effectively thinning the disc player. Save manufacturing costs and increase assembly efficiency.

如圖4所示，本發明之碟片判別方法，首先為開始步驟S 1，將碟片2 7***碟機2 0，感測單元2 1進行偵測步驟 S 2，當任一感測器2 2 1、2 2 2、2 2 3及2 2 4開始動作，立即啟動滾輪2 2，以轉動滾輪2 2的步驟S 3吸入碟片2 7，同時，以計數步驟S4記錄感測單元2 1中感測器動作的數目，且以計時步驟S5開始計時，記錄進片的時間，然後由判斷感測器動作數目減少的步驟S6，藉由不同尺寸碟片具有不同直徑，於直徑通過時所能遮住感測器的數目，決定碟片尺寸，雖使用較密集的感測器可增加判別的碟片尺寸種類，但相對會增加零件成本，本實施例以四個感測器判別8cmAs shown in FIG. 4, the disc discriminating method of the present invention firstly inserts the disc 2 7 into the disc player 20 from the start step S1, and the sensing unit 2 1 performs the detecting step S2, when any sensor 2 2 1, 2 2 2, 2 2 3 and 2 2 4 start the action, immediately start the roller 2 2, and take the step S 3 of the roller 2 2 to suck the disc 2 7, while recording the sensing unit 2 in the counting step S4 The number of sensor actions in 1 is started in timing step S5, the time of filming is recorded, and then step S6 is performed to determine the number of actions of the sensor is reduced, and the disks of different sizes have different diameters when the diameter passes. The number of sensors can be blocked, and the size of the disc can be determined. Although a denser sensor can be used to increase the disc size, but the relative cost is increased. In this embodiment, 8 cm is determined by four sensors.

第10頁 1276051 五、發明說明（6) 及1 2 c m碟片為例，8 c m碟片可遮住三個感測器，而1 2 c _ 片可遮住四個感測器，因此在開始之後，感測器動作的數目會持續增加，一旦偵測出感測器動作的數目減少，就以步驟S 7判定為次種碟片，即8 c m碟片。否則，就進入步驟 S8比較進片的時間是否超過預定的時間，由於碟片可遮住所有感測器的弦長所在的距離，在滾輪2 1的轉速一定下，可計算出碟片前進的所需的時間，本發明為例約為0. 3 秒，超出所需的預定時間未遮住所有感測器，即可以步驟 S 7判定為次種碟片，如計時經比較仍未超過預定時間，則至下一步驟S 9判斷是否所有感測器動作，即遮住所有感測器，如已遮住所有感測器則可以步驟S 1 0判定為主要碟片，1 2 c m碟片，否則重覆步驟S 3轉動滾輪2 2繼續吸入碟片27。因此，本發明之碟片判別方法，以進片時間及感測器動作數目的變化等兩道判別碟片尺寸的程序，交叉判斷方式，可快速判別出碟片尺寸，又可避免碟片誤觸判別機構，讓碟機快速、正確反應所承接碟片的尺寸，提高可靠性。此外，如圖5所示，本發明之碟片判別方法亦可用於篩選適用碟片尺寸之碟機，其中開始步驟R 1、偵測步驟 R 2、轉動滾輪的步驟R 3、計數步驟R 4、計時步驟R 5、判斷感測器動作數目減少的步驟R6及步驟R8比較進片的時間是否超過預定的時間，與前述碟片判別方法之步驟S 1至S 8所用的過程及方法相同，不同處在於當步驟R6判斷感測器動Page 10 1276051 5. Inventive Note (6) and 1 2 cm discs, for example, 8 cm discs can cover three sensors, while 1 2 c _ sheets can cover four sensors, so After the start, the number of sensor actions will continue to increase. Once the number of sensor actions is detected to decrease, it is determined in step S7 as the next disc, that is, the 8 cm disc. Otherwise, the process proceeds to step S8 to compare whether the time of feeding into the film exceeds a predetermined time. Since the disc can cover the distance of the chord length of all the sensors, the rotation of the roller 21 can be determined, and the advancement of the disc can be calculated. The time required for the present invention is about 0.3 seconds, and all the sensors are not blocked beyond the required predetermined time, that is, the next type of disc can be determined in step S7, if the timing is still not exceeded. Time, then to the next step S9 to determine whether all the sensors operate, that is, to cover all the sensors, if all the sensors have been blocked, then it can be determined as the main disc in step S1 0, the 1 2 cm disc Otherwise, the step S3 is repeated to rotate the roller 2 2 to continue to suck the disc 27. Therefore, in the disc discriminating method of the present invention, two discriminating disc size programs, such as a change in the feeding time and the number of sensor movements, and the cross judging method can quickly discriminate the disc size and avoid disc discrepancy. Touching the discriminating mechanism allows the disc player to quickly and correctly reflect the size of the discs it receives and improve reliability. In addition, as shown in FIG. 5, the disc discriminating method of the present invention can also be used to screen a disc machine of a suitable disc size, wherein the step R1 is started, the detecting step R2, the step R3 of rotating the roller, and the counting step R4 are performed. The timing step R5, the step R6 of determining the decrease in the number of sensor actions, and the step R8 comparing whether the time of the film advance exceeds a predetermined time is the same as the process and method used in the steps S1 to S8 of the disc discriminating method. The difference is that when step R6 determines that the sensor is moving

1276051 五、發明說明（7) 作數目減少，或步驟R8計時超過預定的時間時，進入步驟 R 7反轉滾輪，使滾輪進行退片，以完成退片步驟R 1 1。反之，在步驟R6判斷感測器動作數目非減少，且步驟R8比較進片的時間未超過預定的時間時，則由步驟R 9判斷是否預定數目感測器動作，即遮住預定數目的感測器，此預定數目的感測器需視碟片的尺寸及感測器的密度適當選定。如未遮住預定數目的感測器，回至步驟R 3繼續轉動滾輪進片，如已遮住預定數目的感測器則以步驟R 1 0完全進片。對於適用特定碟片尺寸的碟機，本發明之碟片判別方法於篩選碟片尺寸時，即可將不適用的碟片或誤***的異物，在未完全進片下迅速排出，避免進片後卡入碟機，導致碟機及碟片雙重損壞，達到保護碟機及碟片的功效。以上所述者，僅為用以方便說明本發明之較佳實施例，本發明之範圍不限於該等較佳實施例，凡依本發明所做的任何變更，於不脫離本發明之精神下，皆屬本發明申請專利1276051 V. INSTRUCTIONS (7) When the number is reduced, or step R8 is timed over a predetermined time, the process proceeds to step R7 to invert the wheel, and the roller is unloaded to complete the unwinding step R 1 1 . On the other hand, if it is determined in step R6 that the number of sensor actions is not reduced, and the time in which the step R8 compares the incoming film does not exceed the predetermined time, it is determined in step R9 whether a predetermined number of sensors are operated, that is, a predetermined number of senses are blocked. The predetermined number of sensors are appropriately selected depending on the size of the disc and the density of the sensor. If the predetermined number of sensors are not obscured, returning to step R3 continues to rotate the roller feed, and if a predetermined number of sensors have been blocked, the film is fully fed in step R10. For a disc player that is suitable for a specific disc size, the disc discriminating method of the present invention can quickly discard unsuitable discs or mis-inserted foreign objects when the disc size is screened, thereby avoiding the disc insertion. After the card is inserted into the disc player, the disc player and the disc are double damaged, and the effect of protecting the disc player and the disc is achieved. The above is only a preferred embodiment for facilitating the description of the present invention, and the scope of the present invention is not limited to the preferred embodiments, and any changes made in accordance with the present invention may be made without departing from the spirit of the present invention. Are all patents of the present invention
