Description

[Detailed Description of the Invention] [Object of the Invention] (Field of Industrial Application) The present invention is directed to a digital audio tape player (DAT).
The present invention relates to a cassette holder for holding a cassette inserted into the device in a magnetic recording device such as a DVD player (VTR) or a video deck (VTR).

(Prior Art) Cassettes such as DATs and VTRs are provided with lids that can be opened and closed for the purpose of protecting the tape. This lid is normally locked with a spring, and is configured such that by pressing a lock release claw on the bottom of the cassette, the lock is released and the lid is opened. Therefore, as a cassette holder for loading and unloading this type of lidded cassette into and from a magnetic recording apparatus, a cassette holder as shown in FIG. 2 (A>) has been proposed.

That is, in FIG. 2(A), one side of the bottom of the cassette holder 1 is pressed with a lid lock release air 2 provided at the bottom end of the cassette C as shown in FIG. 2(B). An engaging protrusion 3 is provided for releasing the lock. Further, the lid lock release wind 2 is caused by a spring.
Always biased to the locked position. In addition, Figure 2 (8)
The middle 4 is covered by the lid of cassette C.

In a conventional cassette holder having such a configuration,
When the cassette C is inserted into the cassette holder 1 and pushed toward the back, the lid rotor release claw 2 provided at the bottom end of the cassette C engages with the engagement protrusion 3 formed on the bottom of the cassette holder 1. When engaged, the lid lock release wind 2 is pressed toward the front side against the biasing force of the spring. As a result, when the lid lock of the cassette C is released and the cassette C is lowered to the play position, the lid 4 of the cassette C is opened by a lid opening means (not shown), the internal tape portion is exposed, and the cassette C is in the play state. Set.

On the other hand, when the cassette C is ejected, the cassette holder 1 is driven upward by the driving force of the motor, the lid 4 is closed at this stage, and then the cassette C is ejected to the front side. When the cassette C is pushed out to the front, the cassette holder 1
The engagement protrusion 3 provided on the bottom of the cassette C disengages from the lid release claw 2 provided on the bottom end of the cassette C, and the lid lock release air 2 acts in the locking direction due to the biasing force of the spring, and the cassette C is released. C is locked again.

However, in the conventional cassette holder having the above configuration, when the cassette C is inserted and the lid lock release wind 2 engages with the engagement protrusion 3 provided on one side of the bottom surface of the cassette holder, In addition, a force that presses the cassette C toward the front side is applied to the engaging portion by the urging force of a spring provided in the lid lock release wind 2. Since this pressing force acts only on the side where the engaging protrusion 3 is formed, the cassette C may shift diagonally within the cassette holder 1, and the cassette C may not move into the cassette holder 1.
There was a drawback that the mounting operation could not be performed accurately.

In addition, as mentioned above, if the cassette C is installed diagonally, when the cassette C is lowered to the play position, the cassette positioning pin provided on the bottom of the chassis will not fit into the cassette engagement hole. There was also a drawback that the cassette could not be fitted properly and the cassette could not be inserted into the tape player accurately.

(Problems to be Solved by the Invention) As mentioned above, in the conventional cassette holder, when the cassette is installed, the cassette may be installed diagonally, making it impossible to perform an accurate installation operation. .

The present invention aims to eliminate the above-mentioned problems, and prevents the cassette from being VC@ with a diagonal shift.
The purpose of the present invention is to provide a highly reliable cassette holder that enables accurate mounting operation.

[Structure of the Invention] (Means for Solving the Problems) The cassette holder of the present invention has the following features on the top surface of the cassette holder:
It is provided with a plate spring that presses the cassette downward and a claw that presses the cassette downward when loading the cassette is completed.

(Function) In the cassette holder of the present invention having the above configuration, the leaf spring provided on the top surface of the cassette holder allows
By pressing the cassette installed in the cassette holder from above, it is possible to suppress the pressing force that pushes the cassette lid unlocking wind towards you when inserting the cassette, and prevent the cassette from shifting diagonally. The claw provided on the cassette prevents the cassette from lifting up when loading the cassette, allowing the cassette to be installed accurately.

(Example) Hereinafter, an example of the present invention will be specifically described based on FIG. Incidentally, the same members as those of the conventional type shown in FIG. 2 are given the same reference numerals, and the description thereof will be omitted.

*Configuration of the Embodiment* As shown in FIG. 1, on the top surface of the cassette holder 1, a leaf spring mounting portion 11 and a pawl 12 that presses the cassette downward during cassette loading are formed side by side in the front direction in the cassette insertion direction. has been done. A leaf spring 13 is attached to the upper surface of the tip end of the leaf spring attachment part 11 in a manner that projects forward in the cassette insertion direction. The protruding portion of the leaf spring 13 is slightly bent downward, and with this configuration, the cassette holder 1
The cassette C inserted therein is pressed downward. Further, an elastic member 14 made of rubber or the like is attached to the lower surface of the tip of the leaf spring 13 as a cushioning material.

On the other hand, on the cassette insertion opening side of the cassette holder 1, a dustproof door insertion part 1a that is pushed outward is formed in the same way, and the width W between the dustproof door insertion parts 1a of the left and right cassette holders 1 is The height H and depth D of the dustproof door insertion portion 1a are set to be such that the dustproof door 15 can be inserted therein. The dustproof door 15 is rotatably provided around a shaft 15a.

Effects of this embodiment The lid lock release wind 2 engages with the engagement protrusion 3 formed on the bottom of the cassette holder 1, and the lid lock release wind 2
Push the cassette C toward you against the biasing force of the spring.
Remove the lid roti.

At this time, as mentioned above, the cassette C is moved by the urging force of the spring disposed in the lid lock release wind 2.
A force is applied to push the cassette C toward the front, but the leaf spring 13 formed on the top surface of the cassette holder 1 presses the cassette C downward, preventing the cassette C from shifting toward the front. can.

Then, when the cassette C is inserted to the deepest position and lowered to the play position, the lid 4 is opened, the internal tape portion is exposed, and the cassette C is set in the play state.

By the way, when the cassette C is lowered and the lid 4 is opened, components of the lid opening force act in the direction of ejecting the cassette C (towards the front) and in the upward direction, but if this component is large, the cassette The plate spring 13 is pushed upward via the cassette C, and the cassette C is installed in a floating state.

On the other hand, in this embodiment, since the claw 12 for pressing the cassette C is provided on the top surface of the cassette holder, even if the leaf spring 13 is pushed upward when the cassette C is lowered, the claw 12 is not replaced. Since the cassette C can be suppressed and fixed downward, the cassette C can be mounted accurately.

Furthermore, in this embodiment, on the front side of the cassette holder,
A dustproof door insertion part 1a is formed, and the left and right dustproof door insertion parts 1
Since the width W between the openings a and a is made wider than the width in which the cassette slides, the width of the dustproof door 15 can be increased, and the cassette insertion opening of the escutcheon can be reliably closed to improve the dustproof function.

*Other Embodiments* In the above embodiments, two left and right cassette holders hold both sides of the cassette, but the present invention is not limited to this. For example, the cassette can be held with one member. It can also be applied to a box-shaped cassette holder that holds the whole.

Further, the shape and arrangement of the leaf spring and claw provided on the upper surface of the cassette holder can be changed as appropriate.

[Effects of the Invention] As described above, according to the present invention, the cassette mounted in the cassette holder can be easily adjusted by providing a leaf spring and a claw for pressing the cassette downward on the upper surface of the cassette holder. It is possible to provide a highly reliable cassette holder that prevents the cassette from shifting diagonally and enables accurate mounting operation.
