Abstract

PURPOSE:To prevent a motor from being loaded greatly by turning on a power source for the 1st time when a cassette is inserted manually into a pack guide to some extent and then pulling in the cassette by a motor-driven loading plate. CONSTITUTION:The pack guide is provided with a slidable pack stopper, which is associated with a stopper arm 58 provided rotatably to the frame of a tape player; and the pack stopper is pressed inward by the cassette inserted into the pack guide to rotate the stopper arm 58 by a specific angle, and when a guide roll reaches a driving cam, the motor is powered on for the 1st time to drive the loading plate 40. Then, the stopper arm 58 is driven through the guide roll which is in contact with the driving cam, thereby inserting the cassette into the pack guide manually in the former half period and then by motor driving in the latter half period.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a cassette loading mechanism for a tape player, and particularly to a tape player of the type that uses the driving force of a motor to pull a cassette deep into a pack guide. It depends.

[Technical Background of the Invention] Recently, automation of tape players has progressed, and the loading mechanism for setting the cassette at the playback position of the tape player also utilizes the driving force of a motor, thereby reducing the operating force. Various approaches have been proposed. Among these, the front-insertion type loading mechanism, which is generally widely used in car stereos, allows the cassette to be inserted horizontally into the back kite located behind the insertion opening through the insertion opening in the escutcheon at the front of the tape player. rotates, and its driving force pulls the case 1 to the inner part of the pack guide, and then the entire puncture guide is lowered horizontally to cause the internal cassette 1 to swing onto the reel base.

With such a front-insertion type mechanism, the retraction operation can be automated! ! J' to 11i to 7J just by pushing the hand
Inserting the t-t to the back of the pack guide is difficult because the insertion opening formed in the escutcheon is narrow and it is difficult to operate, and the positioning at the back of the back guide is inaccurate.
When the back guide descends, the reel shaft or back guide bin may hit the case, making it impossible to set it. Therefore, there is currently a strong demand for automation of cassette retraction into the back guide.

[Problems with the Background Art] By the way, this type of loading mechanism requires two operations: pulling the pack into the case 1 and lowering the pack guide (the time required for the entire loading There is a problem that the driving force becomes large and the load on the motor increases.

In particular, if the cassette inserted into the back kite is not retracted quickly, in addition to the psychological dissatisfaction of the user, the user will have to keep holding the cassette until retraction is complete, which will place an extra burden on the loading mechanism. There is a risk that drivers may become distracted from driving due to Karen 1 to 6 in Cars Deleo. Therefore, it is necessary to perform the cassette retraction operation quickly, but doing so will reduce the reduction ratio of the gear that transmits the driving force from the motor to the loading mechanism, which will add load to the motor and cause the motor to overheat.
On the other hand, in order to reduce the load by downsizing the motor (1), the reduction ratio of the gear becomes too large, resulting in a slow loading operation speed. There is.

``Purpose of the Invention The present invention was proposed in view of the problems of the loading mechanism as described above.The purpose of the present invention is to draw the cullet into the back guide at a high speed, and to apply a large load to the motor. The purpose of the present invention is to provide a loading mechanism for a tape player that is free of clutter.

[Summary of the Invention] The loading mechanism of the present invention includes a back stopper that is slidably provided on a pack guide, and this back stopper is connected to a stopper arm that is rotatably provided on the frame of a tape player. Push the Pax 1 Hetsupah to the back side using the cassette that was placed inside the machine, rotate the stopper arm to a predetermined angle, and only when the guide roller provided on the stopper arm reaches the position of the drive cam provided on the loading plate will the motor be activated. By turning on the power, driving the loading plate, and driving the stopper arm via a motor through a guide roller that contacts the drive cam, the first half of the insertion operation of the cassette into the back kite is performed manually, and the second half is a short stroke. Only the motor is driven by the motor, and quick retraction is performed with less motor load.

(2) Operation Next, the operation of the loading mechanism of this embodiment having the above-mentioned configuration will be explained.

■ Inserting the cassette...Figure 1, Figure 2, Figure 4, Figure 4
In the figure, when the cassette is manually inserted into the pack guide 1, the tips of the 7J tubes 1~ are inserted into the guide grooves 6 of the support frame 2 (the abutment part 8 of the pulled pack stopper 7).
At this time, the back stopper 7 is moved toward the back along the guide groove 6. Then, the tip of the stopper arm 58 connected to the back stopper 7 rotates toward the back, and the engaged claw 68, which is provided at the base end of the stopper arm 58, conversely escapes toward the front. , the connecting plate 66 that had been pressed by the engaging claw 68 becomes free, and this connecting plate 66
The arm 50 is pulled counterclockwise by the spring 55 to the control unit 1, which is connected to the switch 50, and the switch suppressing piece 52 installed thereon presses the power off switch 51 to turn it on. 28 is still off, so the motor does not rotate.

The back stopper 7 is manually advanced into the pack guide, and the kite roller 65 of the stopper arm interlocked with this moves to the drive cam 5 of the loading plate 40.
When reaching the part 7, as shown in FIG.
In conjunction with this, the release play 1 moves to the front side of the tape player and presses the abutting portion 23 of the lever 21 of the intermittent gear A7 with the protrusion 1G at the front end thereof. As a result, the switch 1 to the collar 21 rotate counterclockwise, and the switch suppressing piece 27 installed thereon closes the power supply switch 28.
is pressed to turn it on, so that the motor starts rotating and the suction plunger 72 of the rope ink ejection mechanism is energized.

At the same time, as the stopper 21 is rotated from the stopper 21 to the collar 21, the stopper 21 comes off from the recess 20.
B is in a free state. Here, as shown in FIG. 2, the cam wheel lower 31 that is in contact with the middle of the linear return portion of the drive cam 29 formed on the intermittent gear 18 is connected to the power fields 1 to 30.
Due to the force of the spring 30a pulling the drive cams, the two drive cams 1 to 5 slide down the linear return section. Reach the small diameter part.

At this time, power play! 30 moves slightly toward the back of the tape player together with the lower cam wheel, and as the power plate 30 moves, the drive cam 29 rotates slightly counterclockwise. Then, the intermittent gear 18 that had been facing the drive gear 17 at the notch 19 rotates a little and meshes with the drive gear 17, so it rotates counterclockwise under the rotational force of the motor that is turned on. I will do it.

■ Operation of the drive mechanism...Fig. 3, Fig. 5 When the stopper 21 comes off and the intermittent gear A718 starts rotating with the insertion of the levers 1 to 5, a step [notch drive knob J2] appears on the surface of the intermittent gear.
9 also rotates 1, and the cam wheel lower 3 is in contact with its outer peripheral surface.
1 to avoid moving the power brake h30. Here, as described in (2) above, since the cam wheel lower 31 is locked approximately halfway between the linear return portions of the two drive cams,
It once falls to the smallest diameter part of the spiral drive part, and then moves away from the center of the intermittent gear 13 by this spiral drive part. Therefore, the power plate 30 integrated with the cam wheel 1''a 31 first moves slightly toward the back of the tape player, and then the tape player
It will move significantly towards the front side of 7.

Therefore, the L-shaped link 32 is attached to this power plate 30.
The roller-shaped engaging portion 35 of the L-shaped link 34 connected via the O-drive plates 1 to 33 moves forward toward the tape player on the arc-shaped sliding portion 38 of the [] pick plate 36 that was originally in contact with it. Then, as shown in FIG. 5, after engaging with the stepped portion 37, it moves largely toward the inner side.

As a result, the lock plate 36 is pulled by the roller-like engaging portion 335 and moves toward the inner side. At this time, since the switch suppressing piece 27 provided on the stopper 21 of the intermittent gear 18 is pressing the closing switch 28, the suction plunger 72 is already excited and the J-3 plunger is linked by the suction plunger 72. 70 is fixed to the lock plate 36 side. Therefore, the lock plate 36 moves toward the inner side while being held between the receiving roller 71 of the fixed plunger link 70 and the 1''-shaped engagement portion 35. With this movement of the lock plate 3G, the three loading links connected to the front end of the lock plate 3G rotate about their support shafts 39a, so that the opposite side of the three loading links rotates. The pressing portion 39b formed at the end is
Loading plays 1 to 40 will be moved to the front side.

The l''-lar 05 of the collar arm 58 is pressed to rotate the tip of the stopper arm 58 to the innermost part of the support frame 2. Due to the rotation of the tip of the stopper arm 58, the cassette that was manually pushed halfway into the back guide 1 is pulled into the claw part 9 of the back stopper 7, and the driving force of the motor is applied to the back guide 1. You will be drawn in by this.

Even after the retraction is completed, the loading plate 40
As it moves toward the front side, the [
The kite pin 5 of the support frame 2, which was sliding on the horizontal part 561 of the lifted/lowered cam 56, is now r? Depth part 5 of descending cam 56
It will reach the 6a side. Then, the guide bin 5 descends along the tapered portion 56a, and accordingly, the front end of the support frame 2 rotates downward about the support shaft 3 on the back side. As a result, the back guide 1 placed on the front side of the support frame 2 is lowered onto the reel pace of the tape player A7, and the loading of the cassette is completed.

Loading pre that reached the front side in this way = 1 to 4
As shown in FIG. 6, the engagement piece 1G of the lock arm 45 enters into the stepped part 43 of the horizontal part 401), so it is pulled toward the back side by the spring 4.Od. Nevertheless, it is locked in the near side position. Therefore,
The intermittent gear 18 that has rotated once is locked by the switch lever 21, the power plate 30 returns to its original position, and the traction of the roller-shaped engaging portion 35 against the lock plate 36 is released and locked. Even after the plate 36 and the loading link 39 are returned to their original positions by the force of the spring 361 provided on the lock plate 3G, the loading plate 40 remains at the front position and the lifting cam 56 formed on it When pressed, the pack guide 1 holds the case in the installed state.

Also, when the intermittent gear 18 makes one rotation and the jumper 21 returns to its original state, the power supply switch 28 changes to A), but the electromagnetic plunger 72 is attracted/the plunger link 72 pushes the self-protection switch 75. Continued (J), so maintain the excitation state.

■ Eject 1 ~ operation) To perform Eject 1 of J Sera 1 ~, push the lever 80 into the step 1 head and eject 1 again, and the suppression bin 81 of the step cum eject lever 80 will move to the stopper. This will cause the eject arm 50 to hit the arm 53 and be rotated significantly clockwise. Then, the switch suppressing piece 52 of the eject arm 50 separates from the power on switch 51, and power supply to the electromagnetic plunger and motor is stopped. At the same time, eject arm 50
The lock release pin 49 installed in the lock arm 45 moves inside the elongated hole 48 to the left in the figure and presses the edge thereof, so the lock arm 45 rotates clockwise about the support shaft 47. . As a result, the engagement piece 46 of the lock arm 45 and the stepped portion 43 of the loading plate/IO are disengaged, and the loading plates 1 to 40 are moved toward the back of the case 1 to the position before insertion by the force of the spring 40d. .

As the loading plate 40 moves toward the back, the lifting cam 56 provided on the vertical portion 4.0a raises the tip of the support frame 2, and the pack guide 1 supported by it is lifted from the reel base. I'll lift it up. Next, the drive cam 50 installed in the inner horizontal part of the rotating plate 40
is separated from the roller 65 of the stopper arm 58,
The stopper arm 58 moves toward the front side by the force of a spring 63 provided between the tape play unit 7 and the back frame. As the back stopper 7 moves toward the front in the kite groove 6, the back stopper 7 moves toward the front in the kite groove 6.
J set (from within) is pushed out.

Also, as the stopper arm 58 rotates, the engaging claw 68 provided therein pulls the connecting plate 66 toward the inner part.
The eject arm 50 is rotated clockwise by this connecting plate 66. Therefore, the eject arm 50 is rotated clockwise.
The knob and tampering lever 80 returns to its original position and the tampering lever 80 returns to its original position.
Even after the pressing force on the eject arm 50 is released, the eject arm 50 is pulled by the connecting plate 66 and maintains its rotating state, and the switch suppressing piece 52 is pressed against the power off switch 51.
It will be in a state where it has been removed.

[Other Embodiments] The present invention is not limited to the illustrated embodiments, and the following other embodiments may also be adopted.

■ A device that constantly links the drive plate 33 and lock plate 3G without using an electromagnetic plunger or plunger link.

■ Loading plays 1 to 4 are performed directly by the power plate without going through the drive plate 33 or lock plate 3G.
Something that moves 0.

■ Directly turn on the power switch or move the drive mechanism by rotating the stopper arm.

■ The drive mechanism converts the rotational motion of the intermittent gear into linear motion of the power plate by inserting a pin installed on the intermittent gear into a long hole formed in the power plate.

■ A type that uses a rank and a vinyl A to directly drive the rotating plate with an intermittent gear A7.

■ Instead of using an intermittent gear, the driving force of the motor is intermittently transmitted to the loading brake 1 through an idler.

[Effects of the Invention] As described above, in the present invention, the power-on switch is turned on only when the cassette is manually pushed into the pack guide to a certain extent, and thereafter the cassette is pulled into the case 1 by the motor-driven loading plate. Therefore, when comparing the entire retraction stroke of the casel into the pack guide with a motor drive, the required motor driving force is significantly reduced, and the motor load is reduced accordingly. . Therefore, there is an effect that the cassette can be quickly retracted without applying a large load to the motor. In addition, if the entire stroke is performed by the driving force of the motor, the angle of the stopper arm rotated by the driving force l\ will increase, and the shape of the drive cam will become larger or more complicated, causing the rotation of the stopper arm to become larger. However, in the present invention, the retraction stroke is short and the drive cam only needs to rotate the lever arm a little, so the cam can be made smaller and the operation can be made smoother.
