Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cassette tape recorder, and more particularly to a support device for a cassette storage lid.

A supporting device for the cassette storage lid of a general cassette deck is shown in FIGS. 1 and 2.

In FIGS. 1 and 2, the lid 11 is integrally fixed to a holder 13 that holds a cassette 12. As shown in FIGS.

This holder 13 is rotatably supported by a shaft 14 and is biased by a spring 15.

Further, a locking pin 16 is attached to the side surface of the holder 13, and a locking hook-shaped member 1T is rotatably supported in the deck by a shaft 18 in correspondence with this pin 16. 19.

As shown in FIG. 1, when the lid 11 is open, the holder 13 protrudes to the front of the deck and the cassette 12 can be attached or removed, and when the lid 11 is closed, as shown in FIG. The holder 13 is housed in the deck by the engagement of the locking pin 16 and the hook-shaped member 17, and the holder 1
The cassette 12 held at 3 is moved to the cassette operating position within the deck.

In the cassette operating position, the cassette 12 is connected to the spindle 20 in the deck, the capstan 21 . It is engaged with the restraining spring 22 and the like.

Of course, the lid 13 is large enough to close the opening 23 of the deck.

In a cassette tape deck or a portable tape recorder equipped with the above-mentioned conventional device, operability in loading and unloading cassettes is particularly a problem.

That is, when inserting the cassette 12 into the holder 13, the cassette hits the edge of the lid 11, or in the worst case, the magnetic tape exposed from the cassette hits the lid 12, damaging the magnetic tape.

Further, since the cassette 12 only slightly protrudes from the holder 13 and is located inside the lid 11, it is difficult to take out the cassette 12 from the holder 13.

Various attempts have been made to solve the above-mentioned problems, but all of them have disadvantages in that they are complicated in structure, expensive, and can only be applied to specific types of tape recorders.

For example, some devices include a mechanism for pushing the cassette out of the holder to make it easier to take out the cassette.

This is a device that pushes out the cassette in conjunction with the opening operation of the lid, but as shown in Figures 1 and 2, this is a so-called cassette that is inserted into the holder with the head (exposed surface of the magnetic tape) of the cassette first. Not suitable for upright type decks.

That is, there is a high risk that the member pushing out the cassette will come into contact with the tape exposed portion of the cassette, and even if this could be avoided, the structure would be complicated accordingly.

It is also possible to increase the opening angle of the lid and holder, that is, the angle at which they can protrude in front of the deck, to improve the operability of loading and unloading cassettes. There is a limit due to the relationship with the opening angle, and it is necessary to increase the tension of the biasing spring as the opening angle increases.

On the other hand, when closing the lid body or holder, a large force is required for operation, which deteriorates the operability and increases the cost of the spring.

Furthermore, when the lid and holder are closed, a large force is applied, which puts stress on the holder's support mechanism and the various members used to stop the holder, shortening the life of the product.

The present invention solves the above-mentioned problems, and includes the installation of a cassette,
The present invention provides a tape recorder with improved operability for taking out data.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 6.

FIG. 4 shows the cassette installed in the cassette operating position within the deck shown in FIG. 3, and FIG. 5 shows the cassette projected from the front of the deck so that it can be taken out.

The lid 31 is made of, for example, a transparent synthetic resin material and has a size sufficient to close the opening 32 of the deck housing 30.

Legs 33.34 are integrally formed in a part of the lid body 31, and these legs 33.34 are connected to guide portions ( For example, they are engaged with elongated holes 38 and 39.

The cassette holding structure 37 has a cassette holder function capable of holding the cassette with the tape exposed side of the cassette 80 located at the back, and one end thereof is rotatably supported by the substrate 40 by a shaft 41.

Thus, the cassette holding structure 37 is movable through the opening 32 between a first position on the inside of the housing 30 and a second position on the outside.

Also, a pin 3 provided on one leg 34 of the lid 31
One end of a drive lever 42 is pivotally attached to 6.

This drive lever 42 is rotatably supported by the base plate 40 by a shaft 43, and the other end is hooked to one end of a spring 44.

The other end of the spring 44 is hooked to the base plate 40.

Thus, the lid body 31 is supported by the holding structure 37 so as to be movable along its planar direction.

Also, it is rotatably supported by a shaft 41 together with the cassette holding structure 37, and the lid 31 is positioned at a position where it closes the opening 32 of the deck (see FIG. 4) and at a position where the opening 32 is closed.
The position device (see FIG. 5) for opening can be moved between each other.

A locking pin 45 is provided on the side surface of the cassette holding structure 37.

A locking hook-shaped member 46 is provided within the deck in correspondence with the locking pin 45.

The locking hook-shaped member 46 has a hook portion at its tip that engages with the pin 45, and is rotatably supported by the base plate 40 by a shaft 47.

Further, the other end of the locking member 46 engages with a sliding member 48 that is slidably supported by the base plate 40.

This engagement is structured to transmit the downward movement of the sliding member 48 in the drawing to the other end of the locking member 46, as shown in FIG.

A spring 49 is hung between the other end of the locking member 46 and the substrate 40.

Further, a spring 50 is hung between the tip of the sliding member 45 and between the substrates.

A tip of the sliding member 48 is engaged with one end of an operation button 60.

This operation button 60 passes through the front plate 61 of the deck and is supported by a leaf spring 62 as shown in FIG.

The base of the leaf spring 62 is fixed to a support 63 provided on the inner surface of the front plate 61 of the housing 30 by means of a screw 64, and the back surface of the operation button 60 is supported at its free portion.

A cassette tape drive mechanism board 51 is fixed to the board 40 with screws 52 and 53.

A spindle 54 is disposed protrudingly on the drive mechanism board 51, and a capstan 55 and a cassette pressing spring 56 are supported.

Further, a magnetic head 65 and a pinch roller (not shown) are arranged on the opposite side of the cassette pressing spring 56.

This magnetic head 65 is supported by a movable support plate and is linked to a playback operation button 70 shown in FIG. 3, although the details are omitted.

Next, the operation will be explained.

In FIG. 4, a locking pin 45 provided on the side surface of the cassette holding structure 37 or a member attached thereto is engaged with a hook portion of a locking member 46, and the cassette holding structure 37 is located inside the casing 30. The lid 31 closes the opening 32 while the cassette 80 is held in the first position, ie, in a position where the cassette 80 engages the drive member spindle 54 and the capstan.

That is, the pins 35° 36 of both leg portions 33.34 of the lid body 31 are moved by the drive lever 42 to the guide portions 38.3 on the sides of the structure 37.
In this position, the cassette holding structure 37 is in the first position and the lid 31 is set in a position where the opening 32 can be closed.

In this state, the cassette 80 held by the cassette holding structure 37 engages with the spindle 54 and capstan 55 of the tape drive mechanism and is pressed toward the magnetic head 65 by the restraining spring 56.

That is, the cassette 80 is held in the operating position.

Next, by pressing the operation button 60, the cassette holding structure 37 moves to the second position outside the housing 30 through the opening 32, and the lid 31 becomes open.

That is, when the operation button 60 is pressed against the tension of the spring 49, the locking member 46 rotates around the shaft 47, and the hook at the tip engages with the locking pin 45 of the support structure 3T. It comes off.

The unlocked cassette holding structure 37 is connected to the spring 4
4, the cassette holding structure 37 rotates about the shaft 41 via the drive lever 42, so that at least the cassette insertion entrance portion of the cassette holding structure 37 and the opening 32 also protrude to the outside of the deck.

This state is shown in FIG.

By rotating the cassette holding structure 37, the structure 37
The lid 31 supported by the lid 31 also moves accordingly to open the opening 32.

Here, in conjunction with the movement of the cassette holding structure 37 from the first position to the second position, the lid body 31 moves along its planar direction.

That is, the cassette holding structure 37 opens the opening 3 from inside the housing.
During operation, the pin 36 which protrudes outside the housing via the pin 36 and to which the tip of the drive lever 42 is pivoted moves to the opposite side within a guide portion 39 provided on the side surface of the cassette holding structure 37.

Therefore, the legs 34 of the lid 31 supporting the moving pin 36 also follow the movement, so the lid 31 moves along the plane direction from the opening closing position to the opening opening position. and move.

Therefore, when the cassette holding structure 3γ moves from the first position to the second position, the lid 31 retreats downward from the cassette holding structure 37 as shown in FIG. Since the cassette is removed from the cassette, you can put your fingers on both sides of the cassette and pick it up.

Further, when the user presses the lid 31 with a finger or the like to return it to the first position at the second position of the lid 31 shown in FIG. When the drive lever 42 is rotated counterclockwise in FIG. 5, the drive lever 42 is rotated counterclockwise in FIG. 5 about the shaft 43.

For this reason, when the pins 35 and 36 are moved upward in the figure along the guide portions 38 and 39, and the lid body 31 is moved along its surface direction and reaches the first position shown in FIG. , and is returned to the position where the deck opening 32 is closed.

That is, when the user wants to return the lid 31 to the first position, the user can simply push the lid 31 with his or her finger in the direction that rotates the cassette holding structure 37, and the lid 31 cannot be moved in the plane direction. Since this is done automatically, it is extremely easy to handle.

As described above, when the lid body supported by the cassette holding structure that moves in and out through the opening of the deck housing closes the opening, it is in a position that sufficiently closes the opening, but when it is opened, the lid body itself moves and retreats from the cassette insertion inlet of the cassette holding structure, so the operability of taking out the cassette from the cassette holding structure inside the lid or loading the cassette into the cassette mounting part is greatly improved compared to the past. It is something.

The present invention can also be applied to a cassette erect type deck in which the exposed tape portion is inserted into the inner part of the cassette holder.

Furthermore, the present invention allows the opening angle of the lid to be made smaller than in the past, so the tension of the drive spring for opening the lid is small, and the force required to close the lid is small, making the operation light and easy. Since it can be closed, the cassette holding mechanism and receiver of the lid body do not apply excessive force to the stopper member and are effective in protecting the member.

The present invention can be applied not only to decks on which cassettes are mounted vertically, but also to decks and portapules on which cassettes are mounted horizontally or inclined.
