Description

[Detailed Description of the Invention] The present invention relates to a record player that reliably prevents damage to the record disc and the record stylus by controlling the elevation and descent of the pick-up arm in accordance with the opening and closing operations of the lid.

Generally, a record player is provided with a cueing lever to manually raise and lower the pickup, but this increases the number of operating parts, making the operation cumbersome.

Furthermore, with the lid open, there is a risk of accidentally touching the arm while playing a record, or of accidentally dropping the arm onto the record surface and damaging the record stylus.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In FIGS. 1 and 2, 1 is the player body;
Reference numeral 2 denotes a lid that covers the upper surface of the player so that it can be opened and closed; 3, a player board that constitutes the player body 1; 4, a turntable rotatably disposed approximately in the center of the player board 3; and 5, a turntable placed on the turntable 4. A record disc, 6 is a pick-up arm that can be rotated around a fulcrum provided at the rear end, 7 is this arm 6
8 is an armrest attached to the end of the player board 3; 9 is a pick-up attached to the tip of the player board 3;
10 is an arm lifter whose shaft 10a is vertically movably inserted into the bearing 9; 11 is a damper attached to the shaft 10a of the arm lifter 10; 12 is a bearing of the player board 3; A rod is vertically movable in the side plate 3b, 13 is a spring case, and 14 is a coil spring mounted between the collar 12a of the rod 12 and the bottom of the spring case 13. The rod 12 above is the coil spring 1
The player board 3 is always urged upward in FIG. 2 by the urging force 4, and a tip portion 12b that acts as a protrusion projects from the upper end surface of the side plate 3b of the player board 3. Further, the rear end portion 12c of the rod 12 is in contact with the lower end of the shaft 10a of the arm lifter 10.

In the above configuration, when the lid 2 is open,
Since the rod 12 rises and the arm lifter 10 also rises accordingly, the pick-up arm 6 also rises from the record 5. On the other hand, when the lid 2 is closed, the rod 12 is lowered by the weight of the lid 2, and the arm lifter 10 is also lowered accordingly, so that the arm 6 is also lowered toward the record disc 5.

Therefore, when the present invention is applied to a normal record player without an automatic performance function, the user operates the play start lever etc. to rotate the turntable 4, and then opens the lid 2 and manually turns the arm 6. If you move to the desired position and then close the lid 2, the rod 12 will descend and the arm lifter 1 will move accordingly.
0. Since the arm 6 also descends, the pickup 7 can be lowered onto the record 5 and the performance can be started. Then, if you open the lid 2 after the record is finished playing or at any point during the record, the rod 12
can be raised to raise the pick-up arm from the record 5.

Since the cover 2 is always closed while the pick-up 7 is tracing the record 5 in this way, there is no risk of accidentally damaging the record 5 or the stylus of the pick-up 7. When the arm 6 is moved, the arm lifter 10 restricts the pickup 7 to a position elevated above the record 5, so that damage to the record 5 and the needle can be reliably prevented at this time as well.

Furthermore, when the present invention is applied to a record player having an automatic performance function, automatic performance can be performed from the first song by simply closing the lid 2 and operating the performance start lever.

At this time, even if you operate the play start lever with the lid 2 open, the pick-up 7 will only move to the lead-in groove of the record 5.
Since it does not go down, the performance does not start. When the lid 2 is closed, the pickup 7 is lowered and the performance starts from the first song.

If the user wants to play a song from the middle of the record, he or she hands the pickup 5 to a predetermined position on the record, closes the lid 2, and starts playing from there.

Furthermore, if the lid 2 is opened during the performance, the pickup 5 will be raised and the performance will be interrupted.

In addition, when the arm 6 is placed on the armrest 8, the arm 6 may be held above the armrest 8 by hand, and the lid 2 may be closed. Of course, when the arm 6 is brought close to the armrest 8, the engagement between the arm 6 and the arm lifter 10, or between the arm lifter 10 and the rod 12 is automatically disengaged.
The arm 6 may be placed on the armrest 8 with the lid 2 open.

As described above, according to the present invention, since the lifting and lowering of the pick-up arm can be controlled in accordance with the opening and closing operations of the lid, it is possible to greatly simplify the operation of playing a record, and to reliably prevent damage to the record and the needle.
