It is configured to slide on the index plate, and the tonearm is automatically moved and played along with the start signal, and then automatically returned after the performance.

This will be described in more detail based on the accompanying drawings.

The present invention is a main gear device that is composed entirely of the reel device (4) (5) and the motor drive shaft (3); the trip lever 33, the connection between the tone arm feed lever 36 (38) and the nose portion 14 Tripping devices; A switching device comprising a first micro switch 12, a switching lever 46, an operating lever 37, and a contact lever 45; A start and return device comprising a start lever 29, a control plate 21, a repeat lever 17, a slide plate 19, a connecting rod 38, a cam lead in 10 and a reject lever 31; ; A plate size selection device comprising a release lever 7, an index plate 26, and a size selector 25.

This will be described in more detail as follows.

First, the main gear device is formed with a cam groove (2) on the bottom surface is guided by the protrusion (7) of the slide arm (6), the upper surface constitutes the first, second link pieces (4), (5), edge The main shaft 1 having the gear 42 and the weapon gear 43 and the pinion gear 44 meshing with the main gear 1 are formed therein, and the drive shaft 3 having the projection 3 'formed thereon. )

The trip device 6 slides the trip lever 33 at a predetermined position on the slide arm 6, connects the joint lever 35 between the trip lever 33 and the tone arm transfer lever 36, and slide arm 6. The nose portion 14 is configured to push the connecting arm 38 of the tone arm transfer lever 36 at a predetermined position of the tip.

The switch device includes an operating lever 37 interlocked with the switching lever 46 in contact with the J microswitch 12, a contact lever 45 in contact with the pin 13 of the slide arm 6, and the operating lever ( 37 is composed of a tone arm transfer lever 36 and a first micro switch 24 which slide in a predetermined position.

First, the micro-microswitch 12, 24 is the same power supply switch that drives the motor to rotate the drive shaft 3, and the micro-switch 12 is off while the micro-switch 24 is powered on. The moment the switch 24 is turned off with the slide arm 6 rolled back, the first micro switch 12 is turned on.

The start and return device is a star which is connected to the control plate 21 at the same time by the sledoid 28 on one side of the shaft and the other side is connected to the end of the reject lever 31 as a reject rod 32. A lever 29; The distal end is connected to the repeat rod 23, and the pin 22 is locked and released by the hook 20 positioned upwardly, and the central one shaft is brought into contact with the micro-denture 24. 21); A repeater 17 having one end connected to the tip repeater rod 23 of the control plate 21 and the other end contacting the cam lead in 10; A slide plate 19 for guiding the cam lead-in 10 in accordance with the opening and closing of the repeat lever 17; A release arm 8 which is touched at a predetermined position of the slide arm 6 and contacts the hook 20; The connection arm 38 extending downward to the tone arm transfer lever 36 is pushed by the cam lead in 10; consists of.

The pin size selecting device includes a size selector 25 having one end connected to a rod 47 connected by an operating butt (not shown) about its axis, and the other end having a space portion 53 having two kinds of widths as internal surfaces; The inclined contact surface 40 is formed in one direction from the shaft, and at the same time, one end constitutes a two-stage jaw portion 41 and 41 ', and the other end is restricted by the space portion 53 of the size selector 25. An index plate 26 having; The concave inlet portion 16 is formed on a predetermined portion of the slide arm 6 to form the left, right wall portions 49 and 50 so that one end thereof corresponds to the wall portions 49 and 50, and the other end is And a release lever 27 configured to contact the inclined contact surface 40 of the index plate 26.

Reference numeral 15 is a queuing part, 18 is a spring, 20 'is a hook spring, 26' is a spring, 28 is a solenoid, 31 'is a spring, 32 is a solenoid, 34 is a connecting pin, and 51 is a space of a slide plate.

The tone arm of the present invention configured as described above is automatically transported and returned as follows.

When the start butter (not shown) is pressed in the city state as shown in FIG. 2, the start lever 29 is pulled by the solenoid 28 operation as shown in FIGS. 3 and 4, and one side of the reject rod The reject lever 31 connected to 30 is pushed, and the other side reverses the control plate 21.

When the J micro switch 24 is switched by the reversed control plate 21, the motor drive shaft 3 is driven, and at the same time, the first link piece 4 rotated by the reject lever 31 drives the drive shaft 3. Of the main gear 3 to the pinion gear 44 of the drive shaft 3, the main gear 3 is engaged with the pinion gear 44. Thus, the main gear 3 is in a normal rotational operation, and at the same time, the pin 22 protruding from the tip of the control plate 21 is caught inside the hook 20 and the repeat rod ( 23, the repeater 17 is rotated about the axis. (3rd state)

As the main gear 3 continues to rotate in the state of FIG. 4, the slide arm 6 connected to the cam groove 2 with the rock bar 7 proceeds to primarily move the contact lever 45 caught on the pin 13. While being released, the first micro switch 12, which is turned off by the switching lever 46, is brought into on-contact so that the driving power is continuously supplied to the drive shaft 3. (At this moment, the micro switch is turned off. See FIG. 6 state).

In addition, the release lever 27 located in the concave portion 16 is pushed by the wall 49 while the slide arm 6 is in progress, so that the inclined contact surface 20 of the index plate 26 is strongly pushed in the index plate 26. ) Rotate it at an angle.

Therefore, it is to be caught in the jaw portion 40 when the tone arm transfer lever 36 rotates. (See Figure 7 Status)

Then, when the protrusion 7 of the slide arm 6 is positioned at the maximum point of the cam groove 2 as shown in the eighth degree, the right advancing of the slide arm 6 is maximized and the left advancing is started thereafter.

As shown in FIG. 8, since the repeater 17 is already out of the space 51 area of the slide plate 19 fixed separately (see FIG. 3), the space 51 travels along the internal surface of the space 51. FIG. The cam lead-in 10 is able to hang the connecting rod 38 of the tone arm transfer lever 36 in an upright position without limitation.

When the slide arm 6 is retracted by the continuous progress of the main gear 1 after the maximum right advancing of the slide arm 6, the cam lead-in 10 is reversed as it is walking between the connections 38, and thus tone arm transfer. The lever 36 rotates about the axis.

At this time, the tone arm transfer lever 36, as described above, the index plate 26 is hung on the foremost part 40 (the initial playing position of 30CM recorder). At the left and right progress of 6), the queuing unit 15 ascends and descends.

That is, the tone arm transfer lever 36 whose rotation is limited by the index plate 26 lowers the tone arm floated by the queuing unit 15 while the slide arm 6 moves left.

In addition, the release arm 8 momentarily pushes the hook 20 at the moment when the tone arm is placed on the record board to start playing (i.e., the moment the slide arm advances to the left), and the hook 20 is spring-loaded. The pin 220 held on the hook 20 is released at the moment, so that the start lever 29, the control plate 21, and the repeat lever 17 which were pulled by the operation of the solenoid 28 are removed. Are all returned to their original positions by the spring force of the spring 18.

Thus, the J microswitch 24 being connected on is turned off, and the reject lever 31 is also restored (see FIG. 10).

In particular, as shown in FIGS. 9 and 11, when the tone arm is moved to the initial playing position of the record plate and the performance starts, the tone arm transfer lever 36 cannot be caught by the jaw portion 40, and thus the tone arm transfer lever 36 cannot be played. Likewise, when the slide arm 6 moves backward, the release lever 27 is rotated by the right wall part 50 to open the index plate 26 to its original position so that the progress of reproducing the tone arm is not hindered.

Further, since the tone arm transfer lever 36 of FIG. 13 is out of the operating lever 37 of the switching device, when the contact lever 45 is returned to its original position by the slide arm 6, the operating lever is independent of the switching lever 46. Only (37) is pulled out so that it does not interfere with maintaining the motor drive power supply state of the first micro switch (12).

After all the devices such as the main gear and the slide arm are completed until the reproducing performance, only the drive shaft 3 rotates the record plate and the performance is performed by the tone arm.

The description of the operation so far described the start function of the tone arm.

Therefore, the automatic return function of tone pressure is demonstrated from FIG. 14 after the performance.

After the tone arm finishes the normal performance on the record plate, the tone arm moves rapidly along the silent part of the record plate, and moves the control link piece 5 on the main gear 1 to the tone arm feed lever 36 with the joint lever 35. The connected trip lever 33 is pushed, and the first link piece 4 on the control link piece 5 is also suddenly pushed and caught by the projection 3 'of the driving shaft 3 which is being rotated. Is rotated (preliminary application means, see Fig. 15).

When the main gear 10 is rotated, the slide arm 6 is moved again. When the right side movement of the slide arm 6 starts, the cushion portion 14 at the tip of the slide arm 6 moves to the tone arm transfer lever 36. By pushing the connection between the 38 and pushes the tone arm transfer lever 36 of the tone arm integral, the state at this time is the state of FIG. At this time, the release lever 27 is pushed by the left wall 49 of the concave portion 16 and releases the index plate 26 supported by the spring 26 'to return it to its original position, and the contact lever 45 is also released. It is in a state.

18 shows the state in which the slide arm 6 has advanced to the right.

At this time, unlike the start operation of the tone arm, since the repeater 17 is positioned in the space 51 area as it is, the cam lead-in 10 catches the repeater 17 before engaging the connection 38. It will return to its original position as soon as it is upright.

Figure 19 illustrates this.

That is, during the start operation, the cam lead-in 10 is moved while pushing the connection 38 as it is in an upright state, but in the state of FIG. 19, the accumulation of the cam-riin 10 is maintained by the repeat lever 17. Since it is not possible to fall to the original position, the connection proceeds to the left side without pushing the connection 38, and the main gear 1 is also returned to the original position by the rewinding operation of the slide arm 6 continuously.

Referring to the operation of the contact lever 45 and the release lever 27 at this time, as shown in Figure 20, when the contact lever 45 is pushed by the slide arm 6, the operating lever 37 is transferred to the tone arm Supported by the lever 36 has little action, only the switching lever 46 is applied to press the first micro switch 12 off.

Before that, the release lever 27 opens the index plate 26 again by the right wall part 50 of the indentation part 16 at the end of the slide arm 6.

FIG. 20 shows that the tone arm returns to its original position and returns to the initial state as shown in FIG.

21 illustrates the direct stop function by the reject button 31. FIG.

That is, when the solenoid 32 connected to the stop button is actuated, the reject lever 31 is actuated regardless of the reject rod 30 to push the first link piece 4 on the main gear 1 to rotate. The gear 42 is caught by the pinion gear 4 and the main gear 1 is rotated by being caught by the projection 3 'of the (3) and out of the inorganic gear portion 43 of the main gear 1.

Therefore, the slide arm 6 is moved by the rotation of the main gear 1, and the nose portion 14 at the tip of the slide arm 6 pushes the connecting rod 38 to rotate the tone arm transfer lever 36. The instantaneous switching device is also turned off to stop the playing operation, which is described with reference to FIG. 22.

The subsequent operation is the same as the automatic tone arm return function.

23 and 24 illustrate a repeat performance function.

The repeat function can be controlled at the stage of restoring the tone arm in place when the tone arm returns to the end of all performances on the record board. In other words, whether auto-returned or playing, the start lever 29, the control plate 21, and the repeat lever 17 are spaces of the slide plate 19 such that the cam lead-in 10 cannot push the connection 38. It was located in the part 51 area | region.

Accordingly, the tone arm is replayed by pulling the repeat rod 52 so that the cam lead-in 10 can proceed without being disturbed by the repeat lever 17 and causing the other end of the repeat lever 17 to be out of the slide plate 19 area. To do that.

Figure 24 illustrates this in more detail.

That is, when the repeat rod 52 is pulled out irrespective of the repeat rod 23, the tip of the repeat lever 17 positioned in the space 51 of the slide plate 19 is deviated so that the cam lead in 10 is upright. It is possible to push the connection between the 38 in the state and in this state the slide arm (6) proceeds to the left in the connection pipe 38 is moved to the tone arm transfer lever 36 can also be returned to the playing state again.

The operation after moving the tone arm transfer lever 36 is omitted because it corresponds to the operation description by FIGS. 3, 9, 11, and 13 for explaining the start function. 52) The pulled state will continue, so after the tonearm returns, it will continue to repeat unless you insert a separate repeat remover.

In addition, there are two kinds of record plates, 17 cm and 30 cm.

Therefore, in the case where the normal 30cm is the record plate, all the functions and operation structures described above are operated.

If the size of the record plate is 17 cm and the tone arm's initial drop position is narrowed, it is necessary to move the tone arm's conveying distance inward.

The operation of the tonearms for the two kinds of record plates by the size selector 25 is explained by FIG. 25 and FIG.

That is, FIG. 25 illustrates the relationship between the size selector 25, the indextex plate 26, and the release lever 27 applied to a 30cm record plate.

The space portion 53 of the size selector 25 is formed in two widths so that when the pin 48 located in the space portion 53 is operated with a short width, the size selector 25 is pulled out. If it is intended to act largely, it is in a state of FIG. 25.

The state of FIG. 25 has already been described in the above-described start function and return function, and in the state of FIG. 26, the pin 48 is operated with a small width so that the index plate 26 rotates even if the release lever 27 is in contact. The angle is reduced so that the tone arm transfer lever 36 can rotate to the jaw portion 41 '.

Therefore, when the size selector 25 is operated with a small width, the size selector 25 is applied to a 17cm record plate, and the 30cm size leaves the size selector 25 as it is so that the pin 48 can be operated largely.

In this way, this proposal can automatically play the performance of the record board only by starting switching, and when the performance is finished, the tone arm automatically returns, stops playback in the middle of the performance, and automatically returns the tone arm, and the performance of the record plate continues repeatedly. At the same time, it has a function to select and play according to the plate size.
