Description

[Detailed description of the invention] This invention consists of a start operating lever, an up/down operating lever that can selectively take up and down positions, and a tone arm receiver that receives the tone arm. The first and second tone arm receivers each receive the tone arm receiver and work together to lift the tone arm receiver independently, and the first and second tone arm receivers are provided with an operating rod, and are provided with a starting lever. By operating the operating lever and moving the up/down operating lever from the up position to the down position during the page interval, or after or before that, the first and second tone arm receivers are moved from the first operating lever to the first. The second tone arm receiver is operated in the direction of , the tone arm receiver is lifted out, the tone arm is lifted out, and the second tone arm receiver is operated by operating the up/down control lever from the down position to the up position. The first tone arm holder automatically moves the tone arm lever in the second direction opposite to the first direction or without operating the up/down operating lever to the up position. The present invention relates to an improvement in a record player in which the tone arm receiver is lifted up by operating in the second direction, thereby causing the tone arm to be lifted up.

In conventional record players of this kind, when starting, the start operation lever is actually operated, and the up/down operation lever is actually operated at the same time as, after, or before the actual operation. Normally, the first and 20th tone arm receiver actuating rods are operated in the first direction and the tone arm receiver is lowered, thereby causing the tone arm to be lowered. Therefore, the operation to lower the tone arm at the start was relatively troublesome.

Therefore, it is an object of the present invention to provide a new record player of this kind that is configured to avoid such occurrences, as will become clear from the detailed description of the embodiments of the present invention with reference to the drawings below. Probably.

Therefore, the operating lever 11 is activated at the forward position of the front plate 10.
5, the operating lever 11 rotates the lever 31 clockwise as seen in the figure via its engaging piece 29 and the inclined surface 32 of the lever 31. Although the lever 37 is rotated counterclockwise via the lever 33, the operating lever 11
When the pressing operation is released, the lever 37 is rotated clockwise again by the force of the spring 35, and the lever 31 is rotated counterclockwise again via the connecting line 33. 31 and the engaging piece 29 of the operating lever 11 to restore the original position, that is, the position where it is not pressed down.

Further, the rear end of the operating lever 12 has engaging pieces 41 and 42 that extend outward, and a shaft 43 that extends laterally and is pivotally connected to a fixed portion of the motor board 1 below the motor board 1. In addition, a locking piece 45 is provided which is biased by the spring 44 and engages with the engaging piece 41, so that the operating rod 12 is attached to the front plate 1.
At the forward position of 0, it is pressed downward against the spring 44 and upwardly pressed to take the respective positions, that is, the down position and the up position.

Further, as shown in FIG. 2, below the motor board 1, there is a gear 54 having a shaft 51 pivotally connected to its fixed part and having notches 52 and 53 cut out from the outer periphery at two positions. The gear 54 is arranged so as to be in mesh with the gear 23 attached to the drive shaft 2, and the claw pieces 5T are provided at positions corresponding to the notches 52 and 53 on the upper surface of the gear 54 via shafts 55 and 56, respectively. and 58 are rotatably attached, and an actuating rod 64 having engaging pieces 62 and 63 rotatably connected to a fixed part via a shaft 61 rotates counterclockwise as seen in the figure. When the notch 52 of the gear 54 is located at a position facing the gear 23, one end of the long gear 54 should be engaged with the claw piece 57 to deflect it toward the disc 22 (the long gear 54). When the notch 53 is located at a position facing the gear 23, it is arranged to engage with the pawl piece 58 and deflect it toward the disc 22 side.

In this case, the engagement pin 6 is attached to the other end of the rotating lever 37 mentioned above.
5 is planted, and the engaging piece 62 of the operating rod 64 is engaged with the operating pin 65, so that the notch 52 of the gear 54 is located at a position facing the gear 23. When the operating lever 11 is operated as described above, the rotating lever 37 is rotated counterclockwise, and the operating rod 64 is rotated as described above through the engaging pin 65 and the engaging piece 62. A disc 25 is configured to rotate clockwise and has an engaging piece 63 attached to the shaft 5 of the tone arm 4 mentioned above.
Therefore, the notch 53 of the gear 54 is located at a position facing the gear 23, and the pin 24 is in a position to engage with the engagement piece 63. When the shaft 5 rotates to the play end position, the operating rod 64 rotates counterclockwise via the pin 24 and the engagement piece 63 as described above.

A rotating lever 68, which is pivotally connected to the fixed part via a shaft 65, is rotated counterclockwise in the drawing by a spring 66, and is received by a stopper piece 67 is connected to the claw pieces 57 and 58 on the outside. It is arranged so that it can be engaged more easily.

Therefore, when operating the operating member 11 as described above with the notch 52 of the gear 54 facing the gear 23, assuming that the entire drive shaft 2 and therefore the gear 23 are rotating, the claw The piece 57 engages with the engagement piece 21 on the shaft 2 to rotate the gear 54, and the notch 53 engages with the engagement piece 21 on the shaft 2.
3, the claw piece 57 is rotated inward by the rotation lever 68 and the engagement piece 21 is rotated inwardly by the rotation lever 68.
If the gear 54 eventually stops at a position facing the gear 23 with its notch 53, and from this state the tone arm 4 rotates to the play end position. When the claw piece 58 engages with the engagement piece 21 to rotate the gear 54, and the notch 52 comes to a position facing the gear 23 or a position in front of it, the claw piece 58 engages with the rotation lever 68.
The gear 54 is rotated inward to disengage from the engagement piece 21, and eventually the gear 54 returns to its original state with its notch 52 facing the gear 23 and stops. is being done.

Further, under the motor board 1, cam plates 71 and 72 are mounted on the above-mentioned shaft 51, and the tone arm receiver, one end of which engages with the cam plate 71, has an operating rod 73 attached to the fixed part of the horizontal shaft 7.
4, so that the operating rod 73
A receiver attached to a receiver shaft 7 extending from the tone arm receiver 6 described above at the other end is adapted to receive the piece 8 from below, and a tone arm return operating rod engages with a cam plate 72 at one end. 75 is pivotally connected via a horizontal shaft 78 to a frame 77 having a vertical shaft 76 pivotally connected to a fixed part, so that the operating rod 75
When the other end rotates while being engaged with the disc 25 attached to the shaft 5 of the tone arm 4, the other end rotates the shaft 5 and therefore the tone arm 4. ing.

In this case, the cam plate 71. The relationship between the actuating rod 73 and the bridge piece 8, including the shape of the cam plate 71, is such that the gear 54 has a notch 5 from the position where the notch 52 faces the gear 23, as described above.
3 and rotates to the position where it faces the gear 23, the other end of the operating rod 73 is pulled down from the piece 8, and the relationship between the cam plate 72, the operating rod 73, and the disc 25 is as follows. Cam plate 72
As mentioned above, including the shape of the gear 54, the notch 53
When rotating from the position where the notch 52 faces the gear 23 to the position where the notch 52 faces the gear 23, the other end of the operating rod 75 engages with the disc 25 and rotates in that state. It is something that exists.

Furthermore, below the motor board 1, the aforementioned operating lever 12 is installed.
The tone arm holder, which extends between the engaging piece 42 of the holder 6 and the lower end surface of the holder shaft T which extends downward from the tone arm holder 6, is pivoted to the fixed part via the shaft 82 which the operating rod 81 extends in the lateral direction. When the operating lever 12 is in the up position as described above, the end of the actuating rod 81 on the shaft 7 side is in a position where it can be lifted up, and the end of the actuating rod 81 is in a position where the end on the shaft 7 side can be lifted up. Therefore, the tone arm support 6 is in a position where it can be lifted up, and if the operation lever 12 is operated from this point to the down position, the end of the support of the operating rod 81 on the shaft 7 side will be lifted from the lower end of the shaft 7. be done to you,
Therefore, as described above, when the other end of the operating rod 73 is lowered from the support piece 8, the tone arm support 6 is lowered.

Therefore, according to the above-mentioned configuration, the tone arm 4 is clamped by the clamper 9, and the up/down operation lever 12 is in the up position, so that the tone arm holder is in the up position, and the holder of the operating rod 81 is on the shaft 7 side. The end of the tone arm holder is in a position where it can be lifted up, the notch 52 on the long gear 54 is in a position facing the gear 23, and the end of the lever 73 on the side 8 of the tone arm holder is in a position where it can be lifted up. Remove the tone arm 4 from the clamper 9 and receive it on the tone arm support 6 while the tip (having the indicator needle) is on the turntable 3. (At this time, the motor for driving the drive shaft 2 is energized and the drive shaft 2 rotates accordingly.) Then, for starting If the operating lever 11 is operated and the up/down operating lever 12 is operated to the down position at the same time, after, or before, the supporting pieces 8 and the supporting shaft 7 side of the operating rods 73 and 81 will eventually be moved. The end of the tone arm receiver 6 and hence the tone arm 5 are pulled down, and the V- state is obtained. From this state, the up/down control lever 12 is moved to the up position. If the operation lever 12 is moved to the down position, the tone arm receiver 6 will be lifted up and the tone arm 5 will be lifted up, and the playing state will be interrupted. When the tone arm 5 is lifted down, the playing state is restarted, and when the play ends from this state, the end of the arm 8 side of the operating rod 73 is lifted up, and the tone arm holder 6 is lifted up. As a result, the tone arm 5 is lifted up, and the shaft 5 is rotated by the operating rod 75, so that the tone arm 5 is guided to the tone arm receiver 6 that can be lifted up and returned to the position of the clamper 9. However, one example of the present invention has the following configuration in addition to the configuration described above.

That is, for example, the start operating lever 11 is provided with an engaging piece 91 that engages with the up/down operating lever 12 which is in the up position when it is operated, so that the up/down operating lever 12 is in the down position. The lever 12 is connected to the start operation lever 11 so that both the arm support operating rods 81 and 73 can be pulled down simply by operating the start operation lever.

In the figure, another cam plate 92 is provided on the shaft 51 of the gear 54 mentioned above, and an operating lever 93 for an operating lever, one end of which engages with this cam plate 92, is attached to a fixed part via a horizontal shaft 94. It is pivotably mounted so that it can rotate, and the support of the operating rod 81 at the other end of this operating rod 93 lifts up the shaft T side, so that when the operating lever 12 is in the down position, this operating lever 12 to return to the up position.

In this case, the relationship between the cam plate 92, the actuating rod 93, and the actuating rod 81, including the shape of the cam plate 92, is such that the position where the gear 54 faces the gear 23 with its notch 53 at the end of play is determined as described above. When rotating the notch 52 to a position where it faces the gear 23, the end of the operating rod 93 on the operating rod 81 side lifts up and engages with the operating rod 81, and its receiver lifts up the end of the shaft 7. This is done in a way that encourages them.

The above is an example of the configuration of the present invention. According to this configuration,
By operating the start operating lever 11, the up/down operating lever 12, which is in the up position, is operated to the down position, and both the tone arm support operating rods 73 and 81 are operated. Since the tone arm support 6 is lifted down, it is easy to operate only the start operation lever 11 at the time of starting, and therefore, it is possible to operate the start operation lever 11 at the time of start and raise it at the same time, after or before that.・Down operation lever 1
This device has a great feature in that it does not require the troublesome operation of conventional record players, which require two operations.

In addition, when an operating lever operating rod 93 is provided as shown in the figure, the operating lever 93 automatically returns the up/down operating lever 12, which is in the down position at the end of play, to the up position. When the tone arm 5 is in a position where it can be lifted up, the trajectory becomes -,
Therefore, there is no inconsistency as in conventional record players in which the up/down control lever 12 is in the down position even though the tone arm 5 is lifted up at the end of play.

The above description is merely an example of the present invention, and various modifications and changes may be made without departing from the spirit of the present invention.
