Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mechanism for transporting a pickup (hereinafter abbreviated as PU) arm to a mounting position and then releasing it in a pickup jar.

Conventionally, this type of release means has been complicated and expensive. The present invention provides a record soleyer having a simple construction and a low-cost release means, and embodiments thereof will be described in detail below with reference to the drawings.

FIG. 1 shows one embodiment of the present invention, in which 1 is P
U-arm 2 is shown as an imaginary line on the board.

3 is fixed on the substrate 2 by a PU shaft, and the PU arm 1 is attached so as to be able to rotate and move up and down about this shaft. Further, the substrate 2 is provided with a stepped hole 2a, a stepped portion 2b, a stepped hole 2C, and a stepped portion 2d. Reference numeral 4 denotes a drive plate, and 4a denotes an eccentric screw provided on the back surface of the drive plate.A connecting rod connected to the eccentric screw 4 makes a swinging motion in the direction of arrow E. 4b is a convex portion, 4C is an outer periphery, and 4d is a notch. 5 is PU on the information board
to the rest position or to the attached position. 5a is a set bin, 5b is a first vertical column located on the same circular locus as the convex portion 4b, and 5-C is a second vertical column. Reference numeral 6 shows a part of the index plate, which has steps such as a rest step, a step for a 12-inch board, and a step for a finch board, and these steps come into contact with the set bin 5a. When P
U is set at the rest position, the 12-inch disc mounting position, and the finch disc mounting position, respectively. 7 is the clamp shaft, 8
is a PU clamp, 8a is a chestnut convexity, 9 is a click spring, and the PU clamp 8 is pivoted around the flange shaft 7, and is click-reversed in the direction of the arrow Ho with the click convexity 8a as a boundary. 8b is the left arm of the PU clamp, 8c is the right arm, and 8d is the contact piece. 10 is a starting board, which has a long hole 10a and a convex part 10b.
It is installed on the back surface of the substrate 2 with the inner shaft of the PUU 3O passed through the elongated hole 10a and the protrusion 10b passed through the stepped hole 2a (see also FIG. 2). 10C is a vertical piece, 10d is a fin, and 10e is a curved surface. Reference numeral 11 denotes a tension spring that urges the activation wall 10 in the direction of the arrow with the elongated hole 10a as a fulcrum. 12 is a starting stick, 13 is a switch lever, 13a
, 13b is a protrusion, 13c is a control plate shaft, 14 is a lever shaft whose upper end is fixed to the board 2, and 15 is a switch for starting and stopping the turntable motor, which is installed on the top surface of the board 2. ing. Further, the lever 13 is installed on the lower surface of the substrate 2, and the protrusions 13a, 13b, control plate shaft 13c, etc. protrude upward through a hole provided in the substrate 2 (see FIG. 2). Furthermore, in the drawing, the protrusion 13a is drawn apart from the drive board 4, but in reality, when stopped, the tip of the protrusion 13a is fitted into the notch 4d, and during play, the tip of the protrusion 13a is inserted into the notch 4d, and during play, the protrusion 13a is drawn away from the drive board 4.
The lower part of the protrusion 13a is in sliding contact with the curved surface 1 of the starting board 10.
It will come into contact with 0e. The protrusion 13b is the switch 15
It is adjacent to Reno 4-. Numeral 16 is a clamp control panel, the base of which is rotatably supported by the control panel shaft 13c, and 15m is a third vertical column extending from the lower surface of the clamp control panel 16 into the step hole 2C. 16b is a bay-shaped space, 16c is a beak, 16d is a member, 16e is a top, and 17 is a weak tension spring.

The operation of this embodiment configured as described above will be explained next.

FIG. 1 shows the stopped state of this embodiment. In this state, when the starting stick 12 is pushed in the direction of the arrow G, the starting board 10 is pushed in the same direction, the convex part 10b separates from the stepped part 2b, and is pulled. Spring 1
It rotates in the direction of the arrow with a force of 1. Then, the curved surface 10e pushes the protrusion 13 & fitted into the notch 4d, rotates the switch lever 13 in the direction of the arrow, and presses the protrusion 13 on the opposite side.
Turn on the switch 15 with b. switch 15 is on
When this happens, the turntable (not shown) starts, and at the same time, the drive board 4 is first rotated in the direction of arrow A, and the PU on the same board is rotated.
The contact piece 8d of the crankshaft 8 hits the top part 16e of the clamp control panel 16 which is moving backward by the rotation of the switch lever 13 in the direction of the arrow, and the PU crank f8 is clicked and reversed in the direction of the arrow width, and the first vertical column is rotated. 5b is clamped between the left arm 8b and the convex portion 4b, resulting in the state shown in FIG. At this time, the activation board 10 is pushed back by the eccentric screw 4a of the drive board 4 and reset, but the switch lever 13 has already been moved to its protrusion 13.
Since a is placed on the outer periphery 4C of the drive panel, it does not move, and the switch 15 remains ON. In the drawing, the protrusion 13a is shown separated from the drive plate 4, but in reality, as stated above, the two are in contact with each other.

In this state, the drive board 4 reaches the ultimate point of rotation in the direction of arrow A, changes the direction of rotation in the direction of arrow A, pushes the clamp control board 16 in the direction of arrow L by the second vertical column 5C, and moves to the third vertical column. 16a is engaged with the stepped portion 2d. Immediately after that, set bin 5
a comes into contact with a predetermined stepped portion of the index plate 6 that has occupied a predetermined position so far, and sets the PU arm 1 to the attached position.

(Figure 4 shows the state immediately before this contact).

When the set bin 5a is set, the first vertical column 5b also stops rotating, but the PU clamp f8 continues to rotate together with the drive board 4 in the direction of the arrow, so the PU clamp 8 is rotated in the direction of the arrow and reversed. Then, the left arm 8b releases the first vertical column 5b. Inde after liberation.

The cross plate 6 retreats in the direction of arrow W (FIG. 5 shows the state at this time). After that, the PU lowers the needle onto the board and starts playing.

When the performance is finished, the drive board 4 rotates in the direction of arrow A, and the convex part 4b hits the first vertical post 5b, causing the guide board 5 to rotate in the direction of arrow A, and the second vertical post 5C pushes the beak part 16c. Click control panel 1
6 in the direction of the arrow O, the third vertical column 16a is removed from the stepped portion 2d, and the switch lever 13 is held only by the contact between the protrusion 13a and the outer periphery 4c of the drive board, so that the drive board 4 is rotated in the direction of the arrow O. When the notch 4d meets the protrusion 13a as it rotates toward the mouth, the protrusion 138 collapses, and the switch lever rotates in the direction of the arrow N, turning the switch 15 OFF and stopping the operation of the player. .

As explained above, according to the present invention, it is possible to release the pink-up at a predetermined position and start playing with a simple and therefore inexpensive structure without relying on a complicated and expensive structure. .
