Abstract

PURPOSE:To attain the shifting operation of an arm base by manual operation by releasing the transmission of a driving force with the turning of the arm base. CONSTITUTION:For shifting an arm base 1 by manual operation, a finger is hooked on a finger part 16 and the arm base 1 is turned in the direction of the arrow C. Thus, an arm 4 is also turned in the direction of the arrow C' and a needle 2 is separated from a record board 22. Simultaneously, a shaft 12 of a pulley 13 is inclined, the pulley 13 is separated from the surface of a guide rib 15 and the communication of the driving force of a driving motor 8 by a speed reducing driving mechanism 14 is released. Consequently, the arm base 1 can be shifted by a manual operation along a guide rail 7. Thus, the arm base by the manual operation can be shifted and operated.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a linear tracking type record player provided with a manually operable driving force transmission mechanism.

<Jubei's technology and its ffff title, α> This type of record player generally has an arm driven by a motor via wires, gears, etc., and has a structure that does not allow the arm to be moved manually. There is. For this reason, it is difficult to perform slight forward and return operations due to motor operation delays, etc., and it is difficult to stop the pickup at a desired position on the record. When the armrest is in the armrest position, it takes about 10 seconds to return it from there to the armrest position, which can be irritating to the user.

Furthermore, in inspection processes on production lines, etc., the longer it takes to return to the armrest, the lower the work efficiency, which is one of the causes of higher costs.

This invention focuses on these problems and enables manual movement for positioning and quick movement! The purpose of this project was to provide a linear tracking type record player capable of recording 14 records.

Means for Solving Problems〉 In order to achieve the above-mentioned object, in the present invention, the arm base to which the arm of the pickup is attached is movable in a straight line along a guide rail and in the direction of movement. By supporting the pickup rotatably along a vertical plane, transmitting the driving force of the drive motor to the arm base to reciprocate the arm base, and rotating the arm base in the direction in which the pickup moves away from the turntable. A driving force transmission mechanism is provided that is configured to release the transmission of the driving force and enable manual movement of the arm base.

Effects> According to the present invention, by rotating the arm base, it becomes possible to manually move the arm base, and fine positioning and rapid movement operations become possible.

<Example> Next, an illustrated embodiment will be described.

Figures 1 to 3 are side views of the main parts, and Figure 4 is a plan view of the same.
An arm 4 equipped with a pickup 3 is moved to P by a fulcrum shaft 5.
It is installed so that it can rotate in the vertical direction as shown in Figure t51, and the guide 6
It is supported so as to be movable linearly along the guide rail 7 and rotatable along a plane perpendicular to the direction of movement. 8 is a drive motor installed on the arm base 1, which includes a motor shaft 9, a ohm 101, a worm wheel 11, and a shaft 7N2.7'-IJ13, which reduces the deceleration wAI! 1Jfi! 14, and an id rip 15 parallel to the guide rail 7 is provided corresponding to the boot 1j13, and furthermore, the arm base 1 is provided with a portion of fins 16.

20 is a turntable, 21 is a center spindle, 2
2 is a record, and 23 is a part of the cabinet.

This embodiment has the above-mentioned configuration, and is similar to the normal glue near F.
The operation of the Ruff King type record player is shown in FIGS. 2 and 3. That is, when set to the performance state, the drive motor 8 operates and its rotation is transmitted at a reduced speed to the brake pedal 3, and the pulley 13 rotates on the surface of the pulley 15, so that the arm base 1 acts as a guide. It moves along the rail 7 and stops at a predetermined position. And up and down movement 8 not shown! Due to this mechanism, the 7-me 4 moves around the fulcrum shaft 5 in the direction of arrow A, and the needle 2 descends onto the record 22, as shown in FIG. 3, to enter the playing state. When the performance is finished, the arm 4 rotates again in the direction of arrow B around the fulcrum shaft 5, the needle 2 leaves the record 22, the drive motor 8 reverses, and the arm base 1 moves to the standby position. and return to the initial state.

FIG. 1 shows a state in which the arm base 1 is manually moved, and the arm base 1 is rotated in the direction of arrow C by hooking a finger on the finger part 16. As a result, the arm 4 also rotates in the force direction of arrow C°, and the needle 2 separates from the record 22. At the same time, the shaft 12 of the pulley blade tilts, and the boot 3 separates from the idler lip 150 surface, and is driven by the deceleration drive mechanism 14. Transmission of the driving force of the motor 8 is released. This operation is possible from either of the states shown in FIGS. 2 and 3, and the arm base 1 can be moved manually along the guide rail 7. Therefore, any order f! 1
It is now possible to quickly move up to, and when you release your hand after moving, Boo January 3 will come into contact with Idrip 15 again,
It automatically returns to the state where it is driven by the drive motor 8.

<Effects of the Invention> As is clear from the embodiments described above, the present invention transmits the driving force of the drive motor by the driving force transmission mechanism by rotating the arm base in the direction in which the pickup moves away from the turntable. The mechanism was released and the arm base could be moved manually.

Therefore, it is easy to stop the pickup at a desired position on the record, and it is also possible to move it quickly. Even if the amount of movement is large, such as when returning to the original position, the movement can be done quickly in about 2 degrees, and the user will not be irritated. Furthermore, in the inspection process on the production line, the pickup can be moved quickly, improving work efficiency and reducing costs accordingly.
