The present invention is to prevent the cassette holder from sagging by repeatedly inserting and ejecting the cassette tape into the car stereo tape player.

In particular, it relates to a cassette tape insertion and discharge device in which a bent portion is provided in the cassette holder, and the bent portion is freely operated vertically along an inclined surface of the deformation hole provided in the holder operating plate.

In the case of inserting and ejecting the compact cassette tape of the conventional mechanism, the inlet side (the tape inserting side) is sag due to misoperation of the purchaser, malfunction of the mechanism, or long term use.

For example, a tension spring was provided on the opposite side of the inlet (opposite to the working rod plate), but this tension spring canceled the elastic force of the eject spring, causing the cassette tape to stop in the middle when the cassette tape was inserted.

In addition, in order to reduce such defective products, the holder hanger of the operating rod plate was prevented from sagging by special heat treatment, but this caused an economic loss because the product became expensive.

Therefore, maximum care must be taken to ensure that no defective products are produced in the product.

In addition, as shown in FIG. 7 which has been used so far, the operation of the lock plate 100 can be stopped by either of the springs 101 and 102 provided on both sides with respect to the lock plate 100. To actuate the holder operating plate.

That is, the spring return plate 200 is operated by applying pressure to the springs 101 and 102 by the action of the push button.

At this time, the return spring 300 is a problem that exceeds the permissible load because the operating angle must be large, the durability has arisen.

For example, when both springs 101 and 102 cancel the elastic force of the return spring 300, the cassette tape which stopped the tape on the cache arm 400 stopped in the middle.

In addition, since the spring 101 and 102 are operated, the lock plate 100 remains the springs 101 and 102 even when the tape cache arm 400 is returned to the discharge position due to any impact during regeneration. There was a risk that the cassette holder fell down without being returned by the same time, and there was a risk that the lock would be easily released to the shock.

Accordingly, the present invention has been made in view of the above-described problems, and is intended to prevent malfunction and misoperation that can prevent the cassette holder from sagging down due to repeated malfunction of the user, and provide a low-cost product. You can do it.

In order to achieve the above object, the present invention provides a main body of a car stereo deck device, a holder operating plate and an eject lever installed on a side of the main body, and a cassette holder guided freely up and down by the holder operating plate, for maintaining the holder. A holder hanger, a spring return plate installed and actuated on the holder hanger, a lock plate provided on one axis and rotated on one axis, a return spring for operating the lock plate forward and backward, and the return spring An apparatus for inserting and ejecting a cassette tape by installing a tape catch arm at one end, the apparatus comprising: a holder operating plate having integrally formed long holes having an inclined surface at predetermined intervals on the side of the deck body; Protruding pieces and the holder hanger are installed to be movable vertically with respect to A lock plate on which rotational movement is freely installed starting from a support point of the protrusion and the holder hanger, a protrusion for engaging with the cutout of the tape catch arm at one end of the lock plate, and a protrusion provided at a position opposite thereto. Characterized in having a.

EXAMPLE

Hereinafter, the insertion and discharge device of the present invention cassette tape with reference to the accompanying drawings 1 to 6 as follows.

1 is a perspective view showing the deck device of the cassette tape of the present invention, Figure 2 is a plan view of Figure 1, Figure 3 is the operation showing the back of the holder hanger, Figure 4 is when the cassette is inserted into the cassette deck of the present invention It is the action figure shown.

1 is a deck device of the present invention, 20 is a holder hanger, 30 is a cassette holder which is connected to the hole 20c formed in the holder hanger 20 and operated up and down.

The holder hanger 20 has a long guide portion 20a formed in the center in the longitudinal direction. For example, a tape catcher arm 40 is inserted into the guide portion 20a to move back and forth freely by the tape. This catch arm 40 forms the notch 40a at the front side, and the pressing plate 40b is formed at the back side.

In addition, a semicircular hole 20b is formed on the right side of the rear end of the holder hanger 20. For example, a return plate 50 freely rotated around the support point c is provided. A hole for installing the return spring 70 is formed at one end of 50, and a return spring 70 having an elastic force is provided between the hole and the tape catch arm 40.

In addition, a lock plate 60 directly below the return plate 50, that is, freely rotatable about the support point c, is integrally installed, and the lock plate 60 is the tape catch arm 40. Protruding piece (60a) is formed by the pressing portion (60b) that is pressed by the pressing plate (40b) of the back) and the rotation is inhibited by the cutout portion (40a) installed in front of the tape catch arm 40 at the front end Is formed.

The cassette holder 30 forms projections 30c fitted to the holes 20c formed in the holder hanger 20, respectively, and bends at a predetermined distance to the side where the eject lever 2 is installed. 30a) and 30b are respectively provided.

In addition, the holder operating plate 3 is installed on the same line as the bent portions 30a and 30b along the inclined surfaces of the deformation holes 3a and 3b to vertically and vertically move. For example, the bent portions 30a and 30b provided on the side of the cassette holder 30 are guided along the inclined surfaces of the deformation holes 3a and 3b of the holder operating plate 3 so that the cassette holder is lowered.

Further, a protrusion 3c is formed above the rear end of the holder operating plate 3, and the deformation holes 3a and 3b have a substantially Z shape.

Reference numeral 5 in the drawings is an eject link.

Referring to the operation and effects of the present invention configured as described above are as follows.

When the cassette tape 80 is inserted into the deck apparatus main body 1, the tape catch arm 40 is fitted to the reel spin-dol hole of the cassette tape.

For example, when the cassette tape 80 is pushed in as it is, the tape catch arm 40 moves in the direction of the arrow e against the pressure of the return spring 70.

At this time, the return spring 70 is the spring return plate 50 and the end of the spring is parallel to the pressure of the spring 70 is '0' (for example, the discharge pressure is in the direction of the arrow f From the point where the insertion is continued and the zero point is passed, the return spring 70 proceeds in the direction of releasing the pressure and the tape catch arm 40 receives the tension force of the spring 70. The tape is automatically inserted even if you take your hands off.

For example, the pressing plate 40b integrally formed with the tape catch arm 40 is pushed backwards, and the pressing plate 60b integrally formed with the lock plate 60 is in contact with each other, so that the lock plate 60 is in contact with each other. ) Is engaged with the cutout 40a of the tape catch arm 40 by rotating in the direction of the arrow a with respect to the support point c.

More specifically, as shown in FIG. 1, the bent portions 30a and 30b formed at a predetermined distance in front of the cassette holder 30 may include the deformation holes 3a of the holder operating plate 3, Guided along the inclined surface of 3b, the cassette holder 30 is lowered.

For example, the bending holes 30a, 30b, which are formed to be movable in the cassette holder 30, are integrally formed in the holder operating plate 3 around the intersections A, B. The cassette holder 30 automatically descends along the inclined surfaces of 3a) and 3b.

For example, the bent portions 30a and 30b integrally formed with the cassette holder 30 receive the elastic force of the spring 4 provided on the holder operating plate 3 and simultaneously with the holder operating plate 3. The cassette holder 30 descends from the intersections A and B of the formed deformation holes 3a and 3b and moves to the intersections A 'and B' and rests on the reproduction of the cassette tape.

That is, since it is locked by the protrusion part 3b of the holder operating plate 3, and the protrusion part 60c of the lock plate 60, the notch part 40a of the said tape catch arm 40 is the lock plate 60. As shown in FIG. By pressing to the end of the protruding piece 60a of the lock plate 60, it becomes impossible to operate.

Then, when ejecting the tape, pressing the eject lever 2 (in the direction of the arrow c) causes the holder operating plate 3 to retract the head portion (not shown), and simultaneously operates the eject link 5, whereby one end of the eject link 5 is operated. The return plate 50 installed in the spring is rotated while receiving the pressure of the return spring 70 along the semicircular groove 20b formed in the holder hanger 20 starting from the support point c. The tape catch arm 40 actuated by this is pushed out in the direction of the arrow f.

Subsequently, the cutout portions 40a of the tape catch arm 40 engaged with the protruding pieces 60a of the lock plate 60 are separated from each other.

For example, the arrow 3c formed on the upper end of the holder operating plate 3 and the holder operating plate 3 locked by the protrusion 60c of the lock plate 60 receive the elastic force of the spring 4 and then the arrow. It stops by advancing in the direction, and as shown in FIG. 3, while releasing the lock, the holder operating plate 3 starts operation by the return spring 70. As shown in FIG.

As described above, the present invention eliminates the tension spring as in the prior art and does not cancel the action force of the return spring by the tension spring, thereby releasing and relocking the lock plate and the tape catch arm in the operating state. Locking is performed and stable operation can be performed even in the regeneration state and the discharge state.

For example, there is an advantage that the cassette holder can be prevented from falling down due to repeated malfunction of the user.
