The first and second guide protrusions are respectively formed, and the first pivotal arm to which the first link member is connected among the pair of pivoting levers has a gap between the connection portion with the connecting bar and the first guide protrusion. It is preferable to form a narrower than the interval between the connecting portion of the second pivotal arm and the second guide projection.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Meanwhile, in describing the embodiments of the present invention, the components of the tape recorder having the same configuration and function as those of the conventional tape recorder shown and described with reference to FIGS. 1 and 2 are given the same reference numerals as before. Reference is made and detailed description thereof is omitted.

3 and 4, a tape cassette housing coupling device of a tape recorder according to a preferred embodiment of the present invention includes a deck chassis 110 and a tape cassette housing 400, and a tape cassette housing 400. The housing includes a housing body 310, a rotation lever 420, and first and second link members 330 and 340.

Deck chassis 110 is responsible for the bottom surface of the deck 100, the deck drive device and the tape guide device is installed on the upper surface. Then, a pair of first slide grooves 116 are formed in the same shape at positions symmetrical to each of the left and right side walls of the deck chassis 110, and a fixing groove 118 is formed in any one of the left and right sides thereof. do.

The housing body 310 detachably accommodates a tape cassette (not shown), and is elevated on the deck chassis 110 by the rotation lever 420 and the first and second link members 330 and 340. It is possible to install. Slide projections 312 are formed at the upper left and right sides of the housing body 310, respectively.

The pivot lever 420 includes first and second pivot arms 421 and 423 and a connecting bar 425. Each of the first and second pivotal arms 421 and 423 is rotatably connected to each of the left and right sides of the housing main body 310 by a first hinge shaft 423a. Each of the lower ends of the first and second guide protrusions 421b and 423b are protruded to slide in each of the pair of first slide grooves 116 symmetrically formed on both left and right sides of the deck chassis 110. Is connected. On the other hand, the connecting bar 425 interconnects the upper ends of the first and second pivotal arms 421 and 423 across the upper portion of the housing body 310, and the housing body 310 and the deck chassis 110 are connected to each other. When connected, the housing main body 310 is pressed downward.

The first and second link members 330 and 340 are rotatably connected to the first and second pivotal arms 421 and 423 by the second hinge shafts 335 and 345. The upper end of each of the second slide grooves 333 and 343 is slidably connected to the slide protrusion 312 of the housing body 310. A fixing member 390 is mounted at a lower end of the second link member 340, and the fixing member 390 is a fixing groove 118 of the deck chassis 110 when the pivoting lever 420 and the deck chassis 110 are connected. Is fitted). According to this, when the housing main body 310 is mounted on the deck chassis 110, one side to which the first link member 330 is connected may not be fixed to the deck chassis 110, thereby being asymmetrically restrained from the deck chassis 110. On the other hand, the fixing of the second link member 340 can be variously performed without using the fixing member 390 and the fixing groove 118, of course.

The coupling device of the tape cassette housing according to the present invention solves the problem that one side of the housing main body 310 rises upward by asymmetrical restraint from the deck chassis 110 by twisting the connecting bar 425 in a predetermined shape. do. That is, the connecting bar 425 is twisted obliquely so that one end of the connecting bar 425 is closer to the deck chassis 110 than the other end, thereby connecting the deck chassis 110 and the housing body 310 to the connecting bar 425. The upper surface of the housing main body 310 is inclined to be inclined in the direction of the deck chassis 110 to solve the above problems. Here, the connecting bar 425 is a deck chassis than one end of the connecting bar 425 connected to the first link member 330, the end of which is not fixed to the deck chassis 110 than the other end connected to the second link member 340. It is desirable to warp to be inclined close to 110.

As described above, various methods may be used to twist the connecting bar 425. The coupling device of the tape cassette housing in the present embodiment changes the connection structure of the rotation lever 420 and the deck chassis 110 so that the connection bar 425 is naturally connected when the housing body 310 and the deck chassis 110 are connected. You can twist it.

In order to twist the connecting bar 425 as described above, the pivoting lever 420 is formed such that the first and second pivotal arms 421 and 423 have asymmetrical shapes. That is, the first and second guide protrusions 421b and 423b formed on the first and second pivotal arms 421 and 423, respectively, and the connecting bars and the first and second pivotal arms 421 and 423, respectively. The first and second pivotal arms 421 and 423 of the pivoting lever 420 are asymmetrically formed so that the sizes of the gaps d1 and d2 between the connecting portions 425 are different from each other. In the case of the small moving deck 100 applied to the camcorder as in this embodiment, even if the difference d3 between the gaps d1 and d2 is 0.5 mm, the above-described function can be sufficiently performed.

Referring to FIG. 5, the tape cassette housing 400 according to the above configuration may include the first and second asymmetrically formed sides of the pivot lever 420 when the pivot lever 420 is connected to the deck chassis 110. Second pivoting arms 421 and 423 are connected to each of the first slide grooves 116 symmetrically formed on both side walls of the deck chassis 110. Accordingly, the distance between the first pivotal arm 421 side of the connecting bar 425 and the bottom surface of the deck chassis 110 is lower than the second pivotal arm 423 side of the connecting bar 425 and the bottom of the deck chassis 110. Narrower than the gap between the faces. That is, one end of the first link member 330 side of the connecting bar 425 is closer to the deck chassis 110 than the other end of the second link member 340 side by connecting the pivot lever 420 and the deck chassis 110. The connecting bar 425 is inclined at a predetermined angle θ so as to be effective. Accordingly, in the same direction as the arrow shown in FIG. 5, the housing main body 310 is urged to be inclined to the housing main body 310 by the connecting bar 425 so that the housing main body 310 is deck chassis 110. One side of the housing body 310 to which the first link member 330 is connected in a state connected to the deck chassis 110 may be prevented from rising above the deck chassis 110. Such an effect of the present invention is mutually installed without forming a pair of slide grooves 116 formed on the side wall of the deck chassis 110, even when using the same rotation lever 320 (see Fig. 1). By forming the height difference of the position to occur can be obtained in the same manner as in the present embodiment. In addition, although not shown, when the first link member 330 is fixed to the deck chassis 110, the inclination direction of the connecting bar 425 is the first and second rotation so as to be opposite to the case in this embodiment. If the arms 421 and 423 are formed, the same effects as in the present embodiment can be obtained.

Meanwhile, in describing the present invention, the present embodiment has been described using only a moving deck applied to a camcorder as an example, but the present invention is not limited thereto, and the housing body 310 may include the pivoting lever 420 and the link members 330 and 340. Of course, if the deck is installed on the deck chassis 110 by lifting and lowering, it can be applied to a tape recorder employing any type of deck.

According to the present invention as described above, fixing one of the first and second link members of the tape cassette housing to the deck chassis in a simple manner such that the connecting bar of the pivoting lever is twisted when the housing body is mounted to the deck chassis. Even if it does not, it can suppress that one side of a housing main body rises upwards. According to this, since only one of the first and second link members may be fixed to the deck chassis, it is possible to exclude the installation of parts for fixing the remaining link members to the deck chassis. Accordingly, the effect of reducing the manufacturing process and manufacturing cost of the product is produced.

While the invention has been shown and described with respect to preferred embodiments for illustrating the principles of the invention, the invention is not limited to the construction and operation as shown and described. Rather, those skilled in the art will appreciate that various changes and modifications can be made to the present invention without departing from the spirit and scope of the appended claims. Accordingly, all such suitable changes, modifications, and equivalents should be considered to be within the scope of the present invention.
