Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cassette holder device for a magnetic recording/reproducing device in which a cassette holder holding a cassette is moved to an operating position so that recording, reproduction, etc. can be performed at that position.

Conventionally, in general cassette holder devices, a guide device for moving the holder body to the operating position is attached to the cassette holder body that holds the cassette using fastening parts such as screws, and also a guide device is attached to the cassette holder body that holds the cassette using fastening parts such as screws. The leaf springs for use were also attached using fasteners.

For this reason, such conventional devices not only require a large number of fastening parts such as screws, but also have poor workability during assembly, resulting in increased costs.

The present invention has been devised in view of these points, and it is an object of the present invention to provide a cassette holder device that can be easily assembled without using fastening parts.

The present invention will be explained below according to embodiments shown in the drawings. Fig. 1 is an external perspective view of one embodiment of the device of the present invention, Fig. 2 is a sectional view taken along line A-A' in Fig. 1,
FIG. 3 shows a sectional view taken along the line B-B, where the cassette holder device includes a pair of left and right cassette guides 1a and 1b molded from an elastic synthetic resin material such as plastic, and a front cover of the cassette at the tip. The cassette holder body is assembled from a plate spring 3 having a lock release protrusion 2 and a cassette holder body punched and bent from a single sheet of steel.

Here, the left and right cassette guides 1a and 1b are the fourth
As can be seen from the exploded perspective view shown in the figure, it is molded almost symmetrically, but only the right cassette guide 1
As will be described later, an insertion hole 5 for attaching a leaf spring 3 and a window hole 6 for exposing a cassette front cover unlocking protrusion 2 into the holder are provided in the holder. The other parts are symmetrical, with guide rails 7a, 7b, 8a, 8b bent outwards above and below the cassette guides 1a, 1b, respectively.
grooves 9a and 9 are provided on the inner surfaces of each other.
b are formed, and locking protrusions 10a, 10 having downward slopes are formed in the central portions of the grooves 9a, 9b.
0b is provided. Further, each of the cassette guides 1a and 1b has a concave portion 11 on the outer surface thereof.
a, 11b are formed, and the respective recesses 11a, 11
Two through holes 12a, 12b, 13a, 1 in b
3b is drilled. Note that each through hole 12a, 1
As 2b, 13a, 13b, there are holding pieces 14a, 14b, 1 in the center that divide each through hole into two vertically.
5a, 15b are left in the shape of a letter, and the lower end thereof is formed in the grooves 16a, 16b, 17a,
17b. In addition, each of the above-mentioned presser pieces 14
A, 14b, 15a, and 15b each have a locking protrusion 18a having a downward slope at the center of their outer surface.
18b, 19a, 19b are provided.

Here, the leaf spring insertion hole 5 is bored extending from the side surface of the concave portion 11b of the right cassette guide 16 to the side surface of the concave groove 9b, and the window hole 6 is bored approximately in the center of the concave portion 11b. ing.

On the other hand, semicircular notches 20 and 21 are previously formed in the cassette holder main body 3 at two locations corresponding to the reel drive portions of the cassette, and grooves 9a, 9b, 16 of the cassette guides 1a and 1b are formed in advance.
Left and right 3 fitted with a, 16b, 17a, 17b
Each engagement piece 22a, 22b, 23a, 23
b, 24a, 24b are bent and each engaging piece 22a, 22b, 23a, 23b, 24a,
Locking holes 25a, 25b, 26 are provided in 24b, respectively.
a, 26b, 27a, 27b are bored.

Furthermore, a locking hole 28 is bored at one end of the front cover lock release plate spring 3.

When assembling the cassette holder device configured as described above, first the left cassette guide 1a is assembled.
When the grooves 9a, 16a, 17a are fitted with the engaging pieces 22a, 23a, 24a of the cassette holder main body 4, and the cassette guide 1a is strongly pushed downward in this state, the engaging pieces 22a The engaging pieces 23a, 24a are slid into the grooves 9a, and the engaging pieces 23a, 24a are slid into the through holes 12a, 13a from the grooves 16a, 17a, respectively, and then the respective locking holes 25a, 26a, 27
The locking protrusions 10a, 18a, and 19a are locked to a.

On the other hand, in the right side cassette guide 1b, the front cover lock release plate spring 3 was previously inserted into the insertion hole 5 from the concave portion 11b side, and the locking hole 28 of the plate spring 3 was inserted into the concave groove 9.
In this state, the grooves 9b, 16b, 17b of the cassette guide 1b are connected to the engaging pieces 22b, 23b, 24b of the cassette holder body 4. , and press the cassette guide 1b firmly downward.

In this embodiment, the left and right cassette guides 1a and 1b can be attached to the cassette holder main body 4 by simply pushing them in from above, as described above.
In this case, once installed, the engaging pieces 23a, 23 of the cassette holder main body 4
b, 24a, 24b are respectively cassette guides 1
Holding pieces 14a, 14b, 15a, 15 of a, 1b
b and each engaging piece 22a, 2
Locking holes 25a, 25b, 26a, 26b, 27a, 27 of 2b, 23a, 23b, 24a, 24b
Each locking protrusion 10 of the cassette guides 1a and 1b is attached to b.
Since the cassette guides 1a, 1b are held upright on both sides of the cassette holder main body 4 with the cassette guides 1a, 10b, 18a, 18b, 19a, 19b locked, the cassette guides 1a, 1b can be fixed with fastening parts such as screws. There is no need to fasten and fix it to the cassette holder main body 4 using the cassette holder main body 4.

Further, as can be seen from FIG. 3, the front cover lock release leaf spring 3 is also held between the engagement piece 22b of the cassette holder main body 4 in the concave groove 9b of the cassette guide 1b, and the locking protrusion of the cassette guide 1b. 1
0b is locked in the locking hole 28 of the leaf spring 3, and the leaf spring 3 can be reliably attached to the cassette guide 1b without using any fastening parts such as screws.

According to the cassette holder device of the present invention, the left and right cassette guides and the leaf spring for releasing the front cover can be easily assembled by simply pushing the cassette guides and the front cover lock release plate springs without using fastening parts, and the work efficiency during assembly is significantly improved. This makes it possible to achieve significant cost reductions.
