Description

[Detailed description of the invention] This invention relates to a record player with a tape recorder, and in particular, when both the record player and tape recorder are operating, it is possible to operate the auto cut button on the record player or the record player automatically This invention relates to a device in which a tape recorder that is about to come to a stop state automatically comes to a stop state, and moreover, when a pick-up arm is raised, the tape recorder automatically comes to a temporary stop state.

In a conventional record player with a tape recorder, the playback sound obtained by the record player is recorded on the attached tape recorder, but if you want to stop recording before the entire record is played, you can switch between the tape recorder and the record player. It is troublesome to have to operate each stop button to stop the machine. When all records have been played, the auto-return mechanism of the record player automatically operates to stop the player, so in this case, only the stop button on the tape recorder needs to be operated, but this is troublesome.

Generally, when listening to the reproduced sound of a record performance, it is done at a location away from a reproduction device including a record player. When listening at such a remote location, operating the record player is very cumbersome. For this reason, record players were provided with an auto-return mechanism. Even if the tape recorder is equipped with this auto-return mechanism, if the tape recorder attached to the record player does not automatically stop when the record is played, it must be stopped from a remote location. If this stopping operation is not performed, the tape will run in vain, resulting in a disadvantage that it is difficult to use the tape efficiently.

In addition, when the performance of a desired song, etc. is finished, or when the pick-up arm is raised to interrupt the performance during the performance, the tape recorder is stopped or paused to stop the tape from running. It is necessary to force it. If such measures are not taken, the tape will run unnecessarily. However, it is extremely troublesome to perform the above operations while or after raising the pick-up arm. The same goes for operating a tape recorder before raising the pick-up arm.

This invention was made to eliminate the above-mentioned drawbacks and troubles, and the sound played by the record player is recorded by the attached tape recorder.
At the end of playback by the record player, if the auto-return mechanism is activated by moving the pick-up arm to the innermost groove or manually operating the auto cut button, the tape recorder will stop. To provide a record player with a tape recorder in which the tape recorder is temporarily stopped.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a system diagram showing an embodiment of the present invention.

Reference numeral 1 denotes a record player, which is equipped with a motor 3 for driving a turntable 7 (FIG. 2) and an auto-return mechanism 5 for automatically returning a pickup arm. A switch 35 is provided within the auto-return mechanism 5 to detect the start of operation of this mechanism. Reference numeral 2 denotes a tape recorder, which is provided with a driving motor 4 for running the tape and an electromagnetic plunger 6 for stopping the tape recorder. This electromagnetic plunger 6 is operated by the switch 35. This motor 3 is connected to a power source (not shown) via a switch 39. Also, the motor 4 is connected to the switch 39 and the switch 37.
connected to the power supply via. This switch 37 is turned off by raising the pick-up arm, and the switch 39 is turned on by rotating the pick-up arm toward the turntable when the auto-return mechanism 5 is not operating. Therefore, when the pick-up arm is on the armrest (not shown), motor 3 does not rotate, and motor 4 also does not rotate even if the operation button of the tape recorder is operated (switch 37 is on, but the switch does not rotate). 39 is off). Even when the pick-up arm is raised above the armrest, the motors 3 and 4 do not rotate because the switches 37 and 39 are in the OFF state. When the pick-up arm is rotated in the direction of the turntable from this state, the switch 39 is turned on and the motor 3 rotates, but since the switch 37 is still in the OFF state, the motor 4 causes the tape recorder 2 to enter the recording state. It doesn't rotate even if I turn it on. After rotating the pick-up arm to the desired position on the record surface and lowering the pick-up arm, the switch 37
is turned on and the motor 4 rotates.

Next, the record player portion of one embodiment of the present invention will be explained using FIGS. 2 and 3.

7 is a turntable, 8 is a pick-up arm, and 9 is a needle storage in a pick-up cartridge.

The turntable 7 is provided above a boss (not shown), and a boss gear 10 is provided below this boss.

A main gear 12 having a notch in which no teeth are formed is arranged on a part of the circumferential surface of the chassis 11, and a feeder plate (not shown) and a clutch (not shown) are mounted on the upper surface of the main gear 12. is installed. A cam 13 that rotates together with the main gear 12 is provided on the lower side of the chassis 11, and a pin 14 is attached to the tip of the cam 13. Further, a lever 15 for operating the pick-up arm 8 is rotatably attached to the chassis 11 with a shaft 16 as a fulcrum. A long hole 17 is formed at one end of the lever 15 so that the approximately middle portion thereof forms a semicircle.
The pin 14 at the tip of is inserted into this elongated hole 17. A sloped portion 18 is integrally formed on the other end of the lever 15, and a pressing protrusion 19 is rotatably attached to the other end of the lever 15, and the pressing protrusion 19 is disconnected from the pressing protrusion 19. A spring 22 is attached between the spring 22 and the raised portion 21 to rotationally bias the pressing protrusion 19 in one direction.
Reference numeral 23 denotes a stopper that regulates the rotational position of this pressing protrusion. A switch 39 is attached to, for example, the lower surface of this lever 15 (see FIG. 3), and a cam 26 is attached to its contact piece 24 via a plate 25. Also, on the lower side of the chassis 11 is a lever 2 for operating a feeder plate (not shown).
7 will be provided. On the other hand, the pick-up arm 8 has a shaft 28.
This pick-up arm rotation shaft 28 is attached with an arm 29 that rotates together with the pick-up arm rotation shaft 28. A pressing plate part 30 that presses the lever 27 when the record rotates to the innermost circumferential groove is integrally formed, and a pin 31 for controlling the opening and closing of the switch 39 is attached. Note that 32 is a shaft for lifting the pick-up arm 8.

Next, parts of the tape recorder according to an embodiment of the present invention, particularly the parts around the operation buttons, will be explained with reference to FIG.

41 and 42 are operation buttons of the tape recorder, the operation button 41 being pressed and locked, and the operation button 42 not being pressed.
Here, it is assumed that the operation button 41 is a recording operation button. These buttons are locked by a button lock stopper 43 which pivots about an axis 44. Also, this button lock stopper 4
3 is configured to rotate together with a lever 46 that is biased by a spring 45. This lever 4
A movable piece of the electromagnetic plunger 6 is connected to the lower end of the electromagnetic plunger 6 via a rod 47.

In such a device, the pick-up arm 8
When the switch 39 is on the rest stand, the pin 31 is pressing the cam 26 and the switch 39 is in the OFF state. At this time, the main gear 12 is in such a state that its notch faces the boss gear 10. Further, the shaft 32 is located on the inclined portion 18 of the lever 15.

If it is desired to record the performance of the record from this state, it is sufficient to press the record button 41 of the tape recorder, operate the tape recorder, and then move the pickup needle 9 onto the record surface. When you hold the pick-up arm 8 by hand and rotate it toward the turntable 7, the shaft 2
8 rotates the arm 29, and the pin 31
is separated from the cam 26 and no longer presses the cam 26, so the switch 39 is turned on. This switch 3
9 is shown in FIG. For example, when the switch 39 is closed, the motor 3 starts to rotate, and the turntable 7 rotates in response to this rotation. Therefore, by placing the pickup needle 9 on the record placed on the turntable 7, the switch 37 is turned on, a performance is made, and the reproduced sound is recorded on the tape recorder. At this time, the main gear 12 is not engaged with the boss gear 10. When the performance is finished and the storage needle is located in the innermost groove of the record, arm 2
When the lever 9 is rotated clockwise when viewed from above, the lever 27 is pushed by the pressing plate portion 30 in the direction of arrow C in the figure. This causes the feeder plate (not shown) to operate, causing the clutch (not shown) to protrude to the outer periphery of the main gear 12, which engages with an engaging piece provided on the boss (not shown) to engage the main gear. 12 rotates slightly in the direction of arrow D in the figure. Therefore, the main gear 12 comes to mesh with the boss gear 10, the rotation of the motor 3 is transmitted to the main gear 12 via the boss gear 10, and the cam 13 rotates in the direction shown by arrow E in the figure according to the main gear 12. Begin to. Since the pin 14 attached to the tip of the cam 13 is inserted into the elongated hole 17 of the lever 15, the lever 15 rotates in the direction indicated by arrow A in the figure. Therefore, first, the shaft 32 resting on the sloped part 18 of the lever 15 lifts up along the sloped part 18 and comes to rest on the part that is not sloped, and the pick-up arm 8 rises and the storage needle 9 is placed on the record. Move away from the board. Further, due to the slight rotation of the main gear 12, the pin 33 provided at the bottom of the main gear 12 presses the lever 34, and the switch 35 is turned on. When the switch 35 is turned on, the electromagnetic plunger 6 is energized, and the record button 41 of the tape recorder is unlocked and brought to a stopped state.

Next, the pressing protrusion 19 biased by the spring 22 presses and rotates the arm 29, whereby the pick-up arm 8 also rotates together and the pick-up arm returns to its original position. In this case switch 3
9 maintains the on state and rotates together with the lever 15. When the cam 13 further rotates in the direction shown by arrow E in the figure, the lever 15 begins to rotate in the opposite direction, that is, in the direction shown by arrow B in the figure, and the shaft 32 supporting the pick-up arm 8 tilts. 18, so that the pick-up arm 8 is lowered onto the rest table. In this state, the pin 31 is not yet pushing the cam 26, and the switch 39
is still in the on state, but as the cam 13 rotates further, the pin 31 pushes the cam 26, turning the switch 39 off and turning off the power to the motor. At this time, the main gear 12 just rotates once, and this notch comes to the original position facing the boss gear 10 and stops.

The case where the pick-up arm has moved to the innermost groove of the record has been explained above, but if you want to interrupt the performance before the pick-up arm moves to the innermost groove, operate the auto cut button (not shown) and press the lever. 27 in the direction shown by arrow C in the figure to operate the auto-return mechanism. In this way, automatic stopping will be performed through the operations described so far.

In this way, after the auto-return mechanism operates, the tape recorder automatically comes to a stop state, and when the auto-return mechanism does not operate, the tape recorder is brought to a temporary stop state by raising the pick-up arm, and the pick-up arm is lowered. This allows the paused state to be released. Note that such an automatic stop operation of the tape recorder is necessary only when both the record player and the tape recorder are used at the same time, and is not required in other cases. For example, as shown in FIG. It is desirable to provide a record player and a tape recorder to release the interlocking operation of the record player and tape recorder.

This switch 48 is switched in conjunction with a normally provided function switch (not shown), and only when the function switch is switched to a state in which records can be played.
This is the off state. Therefore, the terminal 48a connected to the movable piece is connected to the movable piece terminal 37b of the switch 37, and the terminals 48c and 48d are connected to the switch 39. Therefore, when the function switch is set to the AM/FM position so that AM/FM broadcasts can be received, the tape recorder's motor 4 will be directly connected to the power supply without going through switches 37 and 39, and recording will be possible. By operating the button, recording can be performed without being affected by the operation of the record player. Also, when the function switch is set to the TAPE position, the tape recorder can be operated independently in the same way.

Also, when the function switch is set to the RECORD position, the tape recorder will not operate independently as described above, but if the pick-up arm is raised and switches 39 and 37 are turned off, the tape recorder will not operate independently. When it is desired to run the vehicle, it is desirable to provide a switch 40 as shown in FIG. This switch 40 is turned on only when the knob is pressed, and is connected in parallel with a switch 48. By using this switch 40, the tape can be freely run. That is, even if the function switch 48 is in the RECORD position, pressing the switch 40 causes the tape recorder motor 4 to operate. The tape recorder motor can be operated by pressing the switch 40 to bring the tape to the recording position, or by pressing the switch 40 for a predetermined period of time to provide a no-signal portion between the song and the next song to be recorded.

As explained above, in the present invention, the tape recorder is stopped by the automatic stop operation (that is, the auto return operation) of the record player, so it is easy to stop the tape running when the record play ends. Moreover, by moving the pick-up arm up and down, the tape recorder can be put into a pause state or put into a tape running state, so even while selecting, for example, tracks 3 to 5 on the disc by manual operation, the tape recorder side remains unchanged. Since the tape is stopped, unnecessary running of the tape can be prevented, the troubles and drawbacks of the conventional tape can be eliminated, and the structure is simplified, which has great practical benefits.
