Description

[Detailed description of the invention] "Purpose of the invention" (Field of industrial application) This invention relates to a decorative plate structure placed on a cassette tape deck to cover the drive mechanism, reducing the number of parts and making assembly easier. This invention relates to a device that is simplified and eliminates product variations due to dimensional errors.

(Prior Art) Decorative panels and related assembly structures in conventional cassette tape decks are often constructed as shown in the exploded perspective view of FIG. 4A and the side view of FIG. 4B. That is, the cassette half guide 24 is machined on the drive mechanism chassis 21 using a lathe or the like.
and 25 are caulked, and mounting fittings 22 and 23 separately formed of sheet metal or the like are screwed to the side surface of the drive mechanism chassis 21, and the decorative plate 26 for covering the drive mechanism is made of iron or aluminum. It is press-worked from sheet metal, and this is attached to the mounting bracket 22,
The drive mechanism section is fixed to the cut-out tongue piece 27 provided in the tape deck body with screws 28, and by screwing the mounting brackets 22 and 23 to the chassis (not shown) of the tape deck body, the drive mechanism section can be incorporated into the tape deck body. It was.

(Problems to be Solved by the Invention) However, the assembly structure shown in FIGS. 4A and 4B has the disadvantage that a large number of members are required, and the machining dimensions of the cassette half guides 24 and 25 vary. As a result, the cassette half 29 to be loaded and set becomes loose, and the mounting bracket 2
2 and 23 to the chassis of the tape deck main body, the parallelism of the drive mechanism chassis 21 may not be ensured due to dimensional errors in the mounting fittings, and furthermore, the dimensional errors in the decorative board 26 and the mounting of the decorative board 28. Decorative board 2 depending on clearance etc.
There were problems such as the clearance between the cassette half 29 and the cassette half 29 changing.

The purpose of this invention is to provide a decorative board structure that eliminates the above-mentioned conventional drawbacks, reduces the number of parts, simplifies assembly, and eliminates product variations due to dimensional errors.

``Structure of the invention'' (Means for solving problems) The decorative laminate structure of the cassette tape deck of this invention has a drive mechanism section on the back side of the decorative laminate body for covering the drive mechanism section of the cassette tape deck. In addition to providing a mechanical attachment part for attachment, a half guide is provided on the front side to set the cassette half in a predetermined position, and attachment holding parts are provided on both sides to hold it on the tape deck body. , the mechanism mounting part, the half guide, and the mounting holding part are integrally molded from synthetic resin or the like.

(Function) The decorative board main body, mechanism mounting part, half guide, and mounting holding part are integrally molded from synthetic resin or the like.
When the drive mechanism chassis, which incorporates the drive mechanism of the cassette tape deck, is attached to the mechanism mounting part formed on the back side of the decorative laminate body, a half guide is formed on the front side of the decorative laminate body. is arranged at a predetermined position with respect to the drive mechanism section.

Next, the mounting and holding parts formed on both sides of the decorative board body are fixed to the chassis of the cassette tape deck body. As a result, the drive mechanism section is assembled at a predetermined position in the cassette tape deck body, and the drive mechanism section is covered with the decorative board body.

Therefore, there is no need to create special mounting fittings or decorative plates for attaching the chassis of the drive mechanism, unlike in the past, and there is no dimensional error and there is no need to consider the clearance between members.

(Example) An example of the decorative laminate structure of a cassette tape deck according to this invention will be described with reference to FIGS. 1 to 3.

Figure 1 is an overall perspective view, Figure 2 is a side view, Figure 3 is a side view, and Figure 3 is a side view.
The figure is a side view showing a state in which the drive mechanism section is attached.

In the figure, 1 is a drive mechanism chassis in which a drive mechanism is incorporated, 2 is a decorative board main body, and this decorative board main body 2 has a reel drive shaft 1 in the drive mechanism.
A pull-out hole 2a from which the cassette half 1 should protrude is formed, and a mechanism mounting part 3 for mounting the drive mechanism part is provided on the back side, and a half guide 4 for setting the cassette half in a predetermined position is provided on the front side. . 3. The half guides 4, 5, 6 and the attachment/holding part 7 are integrally molded from synthetic resin or the like.

To explain the above structure in detail, the mechanism mounting part 3 has a boss shape and is protruded in four places, with a screw hole 3 in the center.
a is formed. Among the half guides 4, 5, and 6, 4 is a guide for the front and rear direction of the cassette half, and 5 is a guide for positioning the cassette half in the vertical direction.
6 is a reference guide in the left and right direction.

Screw holes 7a are formed at a plurality of locations in the mounting and holding portions 7 formed on both sides of the decorative board main body 2. Further, a positioning boss 8 is formed on the back side of the decorative board main body 2, and the positioning boss 8 is fitted into a positioning hole 12 formed in the drive mechanism chassis 1.

To explain an installation example of the decorative laminate structure configured as described above, the drive mechanism chassis 1 in which the drive mechanism of the cassette tape deck is incorporated is attached to the mechanism attachment part 3 on the back side of the decorative laminate main body 2 through the screw hole 3a. Attach with screws. Half guides 4, 5, and 6 are formed on the front side of the decorative board body 2 to position the cassette half in the front and rear, up and down, and left and right directions, so simply attach the drive mechanism chassis 1 to the decorative board body 2. The above half guide 4,
5 and 6 are arranged at predetermined positions with respect to the drive mechanism section.

Next, the mounting and holding parts 7 formed on both sides of the decorative board body 2 are fixed to the chassis of the cassette tape deck body with screws. As a result, the drive mechanism section is assembled at a predetermined position in the cassette tape deck body, and the drive mechanism section is covered with the decorative board body.

``Effect of the invention'' According to the decorative board structure of the cassette tape deck of this invention, there is a decorative board body to cover the drive mechanism part, a mechanism mounting part to which the drive mechanism chassis is attached, and various parts for setting the cassette half in a predetermined position. The mounting and holding part that should be used to attach and hold the drive mechanism part attached to the guide and the decorative board body to the chassis of the cassette tape deck body is integrally molded, so the number of parts can be reduced without the need for special parts like in the past. The number of assembly steps can be significantly reduced. In addition, the dimensional error of the guide portion that guides the cassette half is reduced, the cassette half can be prevented from wobbling, and the clearance between the decorative board and the cassette half can be held securely without changing. I can do it.

Furthermore, since the decorative board main body and each of the above-mentioned parts are integrally molded, it is possible to significantly improve the drive mechanism itself and the strength of the attachment.
