Description

[Detailed description of the invention] This invention relates to a cassette tape recorder.

Conventional cassette tape recorders generally have a printed wiring board disposed at the rear of the rear cabinet so as to be approximately parallel to the rear panel of the rear cabinet, and the mechanical section and speaker body of the cassette tape recorder are mounted on the printed wiring board. In contrast, they were arranged so that they overlapped in front of them. In such a configuration, the printed wiring board must first be disposed in the rear cabinet, and the mechanical section of the cassette tape recorder must be disposed in the rear cabinet in which the printed wiring board is disposed.

Therefore, when installing the mechanism, there is a drawback that the work space is narrow and the installation work is complicated. Further, the printed wiring board is generally attached with a plurality of screws, which poses a problem in terms of work efficiency. In addition, the printed wiring, mechanical section, and speaker body are arranged so that they overlap, so
There was a problem in that the arrangement of the connection cord for electrically connecting the printed wiring board, the mechanism section, and the speaker body was complicated, and the wiring work was complicated. Still, the speaker body is generally attached to the front cabinet, but the printed wiring board is located behind the speaker body so that it overlaps, which causes poor sound throughput and deterioration of sound quality.

Another problem was that the printed wiring board vibrates due to sound, which tends to cause static, howling, noise, and the like.
Also, in the case of a cassette tape recorder with a radio receiver,
The magnet in the speaker body and the tuner circuit configured on the printed wiring board are likely to be magnetically coupled, and the tuner circuit, especially the intermediate frequency transformer, bar antenna, oscillator, etc., are affected by the magnetic flux from the magnet in the speaker body. Situations such as changes in characteristics or misalignment were likely to occur. Therefore, in recent years, a cassette tape recorder that can solve the above-mentioned problems, reduce manufacturing costs, and improve operability and functionality, and a printed wiring board mounting device suitable for such a cassette tape recorder have been developed. There is a strong demand for the development of speakers, speaker mounting devices, component mounting devices, etc.

This invention has been made in order to deal with the above-mentioned situation, and the mechanical part of the tape recorder, the speaker main body, and the printed wiring board are arranged in the rear cabinet so that they do not overlap each other, and the printed wiring board is arranged between the mechanical part and the speaker main body. By configuring the device to be located above the installation position and approximately perpendicular to the rear plate of the rear cabinet, it is possible to improve operability by making it possible to operate the front panel, without increasing the size of the main body. To provide a force set tape recorder which can improve functionality, is easy to assemble, repair, inspect, etc., reduces manufacturing costs, improves sound quality, and can prevent vibration of a printed wiring board. Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

The speaker bodies 13 and 14 are located corresponding to the speaker accommodating parts 40 and 41, respectively.

Further, the operating devices 27, 28, 29, and 30 are located so that they can be operated from the front. In such a configuration,
Mechanism section 12 of force setting tape recorder, speaker body 1
3, 14, and printed wiring boards 15 are arranged independently in the rear cabinet u so as not to overlap each other.

For this reason, first, the mechanism section 12, the speaker main bodies 13, 14
The work for attaching the printed wiring board 15 to the rear cabinet 11 becomes easier, and the efficiency of the stereo radio cassette assembly work can be improved. Further, the manufacturing cost of the stereo radio cassette can be reduced. Furthermore, since there is no need to remove the mechanism section 12 and the like when repairing or inspecting the printed wiring board 15, for example, the printed wiring board 15 can be easily repaired and inspected. In addition, the speaker body 13,1
Since the printed wiring board 15 is not located behind the printed wiring board 4, sound penetration is improved, and vibration of the printed wiring board due to sound (causing chatter, howling, noise, etc.) can be eliminated. Further, as shown in FIG. 3a, for example, a bar antenna 34a of a tuner circuit configured on the magnet of the speaker body 14 and the printed wiring board 15, an intermediate frequency transformer (
Intermediate frequency transformer (IFT), oscillator, etc. are difficult to magnetically couple, so the characteristics of the intermediate frequency transformer (IFT), bar antenna 34a1 oscillator, etc. may change due to the influence of the magnet in the speaker body 14, or the adjustment may be deviated. It is possible to prevent the situation from occurring.

Regarding this point, conventionally, as shown in FIG.
are arranged approximately parallel to the rear plate of the rear cabinet 11, so that the intermediate frequency transformer of the tuner circuit, the bar antenna,
There have been many cases in which the oscillator or the like is magnetically coupled to the magnet of the speaker body 14, causing characteristics to change or adjustment to be deviated.

Furthermore, in order to prevent such a situation from occurring, the mounting position of the printed wiring board 15 is restricted, making the design of the stereo radio cassette complicated. Next, the printed wiring board mounting device will be explained in detail with reference to FIGS. 4 and 5.

Note that the same = parts as in FIG. 1 are given the same reference numerals. First, in FIG. 4a, the side walls 11c, 11 of the rear cabinet 11
Printed wiring board guides 53 and 54 extending in the direction of arrow (AeB) are integrally formed on the inner surface of the upper end portion of d so as to face each other, for example, by molding. Grooves 53a and 54a are formed in the guide bodies 53 and 54, respectively, along the direction of the arrow (A++B) shown in the figure. Then, the printed wiring board 15 is guided by the grooves 53a, 54a of the corresponding guide bodies 53, 54 at both left and right edges thereof, and is slid in the direction of the arrow (B) shown in the figure.
will be placed in

On the other hand, printed wiring board supports 55 and 56 are integrally formed on the inner surface of the upper end of the rear plate 11a of the rear cabinet 11, spaced apart by a predetermined distance, by, for example, molding. That is, the supports 55 and 56 are located approximately on the same plane as the printed wiring board 15 that is slid along the grooves 53a and 54a, and protrude in the direction of the arrow (^) shown in the figure, and have openings at their protruding ends. Figure b shows an enlarged view of the support 55, and shows the ends of the lower surface of the upper wall 55a of the support 55 and the upper surface of the lower wall 55b in the direction of the arrow (A). The space portions 55c of the support body 55 are tapered so as to be inclined in the same direction and away from each other.Therefore, the space portion 55c of the support body 55 gradually expands in the same direction on the arrow (A) direction side in the figure. Note that the support body 56 is also formed in the same manner as the support body 55, so a description thereof will be omitted here.

Further, on the rear plate 11a of the rear cabinet 11, claws 5r and 58 are integrally formed, for example, by molding, between the supports 55 and 56, at a predetermined interval on the left and right so as to protrude in the eight directions indicated by the arrows in the figure. ing.

Figure C shows an enlarged view of the claw 5r, in which a hook portion 57b having an inclined surface 57a whose lower surface slopes upward toward the tip is formed at the tip of the claw 57 in the direction of arrow 14](A). ing. The claw 57 formed in this manner has elasticity and can be elastically deformed in the direction of the arrow (C++D) shown in the figure. In addition,
Since the claw 58 is also formed in the same manner as the claw 57, a description thereof will be omitted here.

At the edge in the direction of arrow (B) of the printed wiring board 15 that is slid along the grooves 53a and 54a, the claw 57
, 58 are provided with holes 59 and 60, respectively.

In the above configuration, when installing the printed wiring board 15 in the rear cabinet 11, first the guide bodies 53, 5 are installed as described above.
4 along the grooves 53a and 54a of the printed wiring board 15 in the direction of the arrow (6).

When the printed wiring board 15 is slid a predetermined distance, the printed wiring board 15 is supported in the space between the supports 55 and 56 so that the edge in the direction of the arrow (g) in the figure is sandwiched between the upper wall and the lower wall. When the printed wiring board 15 is further slid, the edges of the printed wiring board 15 in the direction shown by the arrow B) come into contact with the inclined surfaces of the claws 5r and 58, causing the claws 57 and 58 to be elastically deformed in the direction shown by the arrow B). let

When the sliding is completed, the hook portion 57b of the claw 57 engages with the hole 59 of the printed wiring board 15, as shown in FIG. Similarly, the hook portion of the claw 58 is engaged with the hole 60, and the printed wiring board 15 is prevented from coming off in the eight directions shown by the arrows in the figure. That is, in FIG. 1A, supports 61 to 65 of a plurality of printed wiring boards 15 are integrally formed, for example, by molding, at a predetermined distance from each other at the upper end of the inner surface of the front surface of the front cabinet 35. The supports 61 to 65 are located substantially on the same plane as the printed wiring board 15 that is slid along the grooves 53a and 54a,
Moreover, as shown in FIG. b (showing the support body 61 as a representative), it is formed in a substantially U-shape that opens toward the sun. (g) The end portions in the direction are formed in a tapered shape that slopes away from each other, and the space portion 61c is formed by the arrow shown in the figure (
B) direction side is gradually expanded in the same direction. 61d is an elastic member.

Note that the supports 62 to 65 are also formed in the same manner as the support 61, and are provided with elastic members. In this way, the support 61
When the front cabinet 35 provided with the components 65 to 65 is combined with the rear cabinet 11 as shown in FIG. and the lower wall 61b.

Furthermore, in this state, the elastic member 61d comes into contact with the edge of the printed wiring board 15 in the direction of the arrow (A) and elastically presses the printed wiring board 15 in the direction of the arrow (A). This prevents the printed wiring board 15 from moving. The other supports 62 to 65 similarly support the printed wiring board 15, and the pressing members provided on the supports 62 to 65 elastically press the printed wiring board. Note that in the above configuration, the supports 55, 56, 61 to 65, the claws 57, 58
This constitutes the means for fixing the printed wiring board. With this configuration in which the printed wiring board 15 is arranged and fixed to the rear cabinet 11 using the Hessrad method, the printed wiring board can be easily and quickly arranged in the rear cabinet with a one-touch operation.

Further, the printed wiring board 15 is fixed by claws 57, 58 and supports 55, 56 at the same time as it is arranged on the rear cabinet 1, and at the same time when the front cabinet J is combined with the rear cabinet V, the support 61 to 65, the printed wiring board 15 is firmly fixed in the assembled stereo radio cassette. Further, since the guide bodies 53, 54, the claws 57, 58, the supports 55, 56, 61 to 65, etc. can be integrally formed on the rear cabinet 11 and the front cabinet 35 by, for example, molding, it is easy to attach the printed wiring board. The device can be constructed easily and inexpensively. In this regard, in the past, the printed wiring board was attached parallel to the rear panel of the rear cabinet using screws, for example, which required a large number of screws, resulting in high costs and complicated installation work. It was hot. In addition, even if the printed wiring board 15 undergoes a shape change such as warping, the ends of the supports 55, 56, 61 to 65 in the protruding direction are enlarged, so that the printed wiring board 15 can be reliably fixed to the support 55. , 56, 61 to 65 and engaged by claws 57, 58.

Further, the shape change as described above is caused by the printed wiring board 15 changing to the guide body 5.
3, 54 grooves 53a, 54a and supports 55, 56, 61
There is also the advantage that this can be corrected by being sandwiched between 65 and 65. Note that the guide body that guides the printed wiring board 15 in a sliding manner and the fixing means that fixes the printed wiring board 15 are not limited to the above configuration, and of course, various other configurations can be implemented.

Next, the mechanism of the force setting tape recorder and the wiring between the speaker body and the printed wiring board will be explained in detail with reference to FIGS. 6 to 9.

The connector 5a is connected to the printed wiring board 15a by a connecting cord 84, and the connector 85 is connected to the printed wiring board 15b by a connecting cord 86. When the printed wiring boards 15a and 15b are disposed on the rear cabinet 11, the connectors 83 and 85 are coupled to establish an electrical connection between the printed wiring boards 15a and 15b. In the printed wiring boards 15a and 15b disposed above and below the rear cabinet 1 unit, operating devices for various operations of the stereo radio cassette are installed, for example, on the bottom edge of the printed wiring board 15a in the direction of arrow (A) and on the printed wiring board 15a. If it is provided on the upper surface of the wiring board 15a, the operation parts Bl, b2, . This allows for front and top operation.

In addition, as shown in FIG. 12A and b, various operating devices Cl
, C2, . . . are provided on the edges of the lower surfaces of the printed wiring boards 15a, 15b in the direction of arrow (A), all the operating devices Cl, C2, . The operation parts Dl, d2, . . . are located above and below the front of the front cabinet, and the stereo radio cassette is constructed so that all operations can be performed from the front. Further, as shown in FIG. 12C, various operating devices are mounted on the printed wiring boards 15a and 15b at the edges of the lower surfaces in the direction of the arrow (A), the edges corresponding to the side walls of the rear cabinet, and the printed wiring boards 15a. If provided on the top surface, the stereo radio cassette can be configured to allow front operation, top operation, and side wall operation. Note that the side walls forming the thickness of the rear cabinet in the longitudinal direction mean the top plate 11b1, side walls 11c, 11d1, and base plate 11e.

Further, as shown in FIG. 15, printed wiring boards 15a, 15b
, 15c, 15d are connected to the mechanism section 12 and the speaker body 13.
, 14 may be arranged such that one pair is arranged above and below the arrangement position, and one pair is arranged on the left and right sides.

Further, for example, one printed wiring board 15 may be arranged at the top and a pair on the left and right, or only one printed wiring board 15 may be arranged as shown in FIG. Also good. In this way, the printed wiring board is attached to the top of the rear cabinet.
In other words, the configuration in which the printed wiring boards are arranged close to at least one of the side walls and the main board and approximately perpendicular to the rear panel of the rear cabinet is a configuration in which the printed wiring boards are arranged close to at least one of the main board and the printed wiring board, and the number of printed wiring boards to be arranged is limited. This means that there is a high degree of freedom.

Therefore, according to such a configuration, the placement position and number of printed wiring boards can be appropriately set so as to obtain the optimum form in accordance with the specifications and purpose of the stereo radio cassette. As a result, the operating device can be placed in an optimal position, which improves the operability of the stereo radio cassette. Since the number of operating devices can be increased, a stereo radio cassette of the same size as the conventional one can be provided with many functions. In addition,
Printed wiring boards are not necessarily printed on the top plate, side walls, or
It goes without saying that it is not necessary to arrange it so that it is substantially parallel to the base plate.

Next, a speaker mounting device having a feature of a speaker support column will be described.

When the speaker bodies 13 and 14 are attached to the rear cabinet 11 as in the stereo radio cassette described in FIG. 1, the following problems may occur. That is, as shown in FIG. 16, due to the manufacturing precision of each part of the stereo radio cassette, there is a gap between the speaker accommodating portion 90 of the front cabinet 89 that is combined with the rear cabinet 87 and the speaker body 88 attached to the rear cabinet 87. The positional shift occurs, and the front end of the speaker main body 88 cannot be accommodated in the speaker accommodating portion 90. In order to solve this problem, it is conceivable to make the speaker support column flexible. Below, the configuration for giving flexibility to the speaker support column is shown in Figures 17 to 2.
This will be explained in detail with reference to FIG.

17 to 20 are cross-sectional views of the stereo radio cassette viewed from the side. First, in Figure 17, 9
Reference numeral 1a denotes a speaker support column main body, for example, having a substantially cylindrical shape and provided on the rear plate of the rear cabinet 87a. That is,
This speaker support column main body 91a is integrally formed with the rear plate so as to protrude in the direction of the arrow (A) shown in the figure.
For example, four such speakers are provided, corresponding to each corner of a substantially rectangular frame of a speaker main body 88a disposed on the rear cabinet 87a. A speaker support portion 92a is provided at the end of each speaker support column main body 91a in the protruding direction. This speaker support portion 92a is formed, for example, in a substantially cylindrical shape, and a spherical portion provided at one end thereof engages with an engaging portion (not shown) provided at an end portion in the protruding direction of the speaker support column main body 91a. As a result, the other end is movably supported by the speaker support column main body 91a. The speaker main body 88a is attached to the free end portion of each speaker support portion 92a at each corner of the frame, for example, by screws or the like (not shown). In this way, a front cabinet 89a is integrated with the rear cabinet 87a to which the speaker body 88a is attached so as to press the speaker body 88a toward the rear cabinet 87a at its inner surface.

By giving flexibility to a part of the speaker support column in this way, even if the speaker main body 88a attached to the rear cabinet 87a is not located in the speaker housing section 90a of the front cabinet 89a, this misalignment can be avoided. The front end of the speaker main body 88a can be reliably accommodated in the speaker accommodating portion 90a through correction.

In other words, the front end of the speaker body 88a can be brought into uniform contact with the buttful surface of the speaker accommodating portion 90a,
It is possible to radiate sound waves faithfully. Furthermore, such a configuration is not an expensive means of increasing the manufacturing precision of parts, but can be implemented simply and at low cost. FIG. 18 shows a modification of the flexible speaker support column. In the figure, 91b is a speaker support column main body, for example, cylindrical, provided on the rear plate of the rear cabinet 87b.

Similar to the speaker support column body 91a shown in FIG. 17, the four speaker support column bodies 91b are integrally formed on the rear plate by, for example, molding. The protruding direction of each speaker support column main body 91b, that is, the illustrated arrow (,A)
A flexible speaker support portion 92b is provided at the end portion so as to protrude in the direction of arrow (A) in the figure. That is, the speaker support portion 92b includes a cylindrical portion 93b and a spherical portion 94 integrally formed on one end side of the cylindrical portion 93b.
It consists of b. The other end of the cylindrical portion 92b is implanted, for example, at the end in the protruding direction of the speaker support column main body 91b. The speaker support column main body 91b and the speaker force support portion 92b constitute a speaker support column. A speaker main body 8 is provided at the end of the speaker support portion 92b in the protruding direction.
8b is attached. That is, as shown in FIG. 1B, a through hole 95b, for example, is provided at the corner of the frame of the speaker body 88b, and a notch 96b is provided at a part of the edge of this through hole 95b. And the speaker body 8
8b is attached to the speaker support portion 92b through the through hole 9.
5b through the spherical part 94b, and then rotate the speaker body 88b so that the boundary between the spherical part 94b and the columnar part 93b is engaged with the notch 96b, and the process is completed. on the other hand,
In the front cabinet 89b, an engaging part (not shown) is provided at a portion corresponding to the spherical part 94b of the speaker support part 92b, and the spherical part 94b engages with this engaging part when the front cabinet 89b and the rear cabinet 87b are combined. will be combined.

At this time, the speaker main body 88b has a cylindrical portion 93 of the speaker support portion 92b in its frame portion as shown in the figure.
b and the front cabinet 89b. Even in such a configuration, the same effects as in the previous configuration can be obtained.

FIG. 19a shows another modification of the speaker support column, and the speaker support column includes, for example, a substantially cylindrical speaker support column main body 91c with a large diameter, and a protrusion of the speaker support column main body 91c. For example, it includes a small-diameter speaker support portion 92c integrally formed at the directional end portion.

The speaker support portion 92c is flexible, and has, for example, a notch at its protruding end portion for holding the speaker body 88c. Therefore, the speaker main body 88c is located at the front at each corner of the frame 93c.
It is held between the notches of the speaker support portion 92c. For this reason, the frame 93c is, for example, a speaker support portion 92c.
The portion corresponding to the notch is formed into a tapered shape that becomes thinner toward the edge, so that it can be well held in the notch. In this way, the speaker main body 88c is attached to the speaker support column main body, and the front cabinet 89c
When the front cabinet 89c is combined with the rear cabinet 87c, the front cabinet 89c comes into contact with the end of the speaker support part 92c in the protruding direction, for example, as if pressing, and the speaker body 88c
Make sure that it does not come off. Note that FIG. 1A describes the case where the speaker support portion 92c is integrally molded with the speaker support column main body 91c, but for example, as shown in FIG. It may be provided separately.

Furthermore, a protrusion 93d protruding in the direction of arrow (B) in the figure is provided at a portion of the front cabinet 87d corresponding to the speaker support section 92d, so that the front cabinet 89d can be attached to the speaker support section 92d after the rear cabinet 87d and the front cabinet 89d are combined. By increasing the pressing force,
Speaker body 8 in the notch of speaker support portion 92d
The support for 8d may be strengthened. Even in such a configuration, the same effects as in the previous configuration can be obtained. FIG. 20 shows a front cabinet 89 installed to prevent the speaker body 88e from shifting even if vibrations, shocks, etc. are applied to the assembled stereo radio cassette.
An elastic member 91e is provided in the speaker accommodating portion 90e on the inner surface of the speaker.

In such a configuration, the front end of the speaker body 88e is always connected to the rear cabinet 8 by the elastic member 91e.
The speaker body 88e is elastically pressed toward the side of the speaker body 88e, so that the speaker body 88e will not be displaced even if vibrations, shocks, etc. are applied to the stereo radio cassette.

Such a configuration is effective when the speaker support column 92e has flexibility. Here, the elastic member 91e may be provided continuously along the outer peripheral shape of the front end of the speaker body 88e, or may be provided at predetermined intervals. Note that the configuration for imparting flexibility to a part of the speaker support column is not limited to the configuration described above, and it goes without saying that various other configurations can be implemented. Next, a speaker mounting device having positioning means provided between the front cabinet and the speaker body in order to correct misalignment of the mounting position of the speaker body will be described.

FIG. 21a is a diagram showing an example of the speaker accommodating section viewed from the inner surface side of the front cabinet 97a. That is, 98
a is the buttful surface of the speaker accommodating portion. The front end of the speaker body 101a (see b in the same figure) is brought into contact with this buff-full surface 98a. For this reason, Batsuful side 9
8, for example, attaches a predetermined position on the inner surface of the front cabinet 97a to the frame 102a of the speaker body 101a (FIG.
It is formed by forming a concave portion along the outer circumferential shape of (see). A through hole passing through the front and back of the front cabinet 97a is provided approximately in the center of the full surface 98a.
For example, a speaker net 99a is provided here. Note that forming the buff-full surface 98a as a concave portion and providing a through hole can be done, for example, in the front cabinet 97.
It is integrally formed by molding etc. at the time of forming a. Furthermore, on the full surface 98a, there are, for example, pairs of spherical members 100 for positioning, for example, on the upper and lower sides, and on the left and right sides.
A is provided.

This spherical member 100a has a buttful surface 9 as shown in FIG.
8a, the spring 105a is inserted into the hole 104a set in the direction of the arrow (8a) so that it can be freely fitted in the direction of the arrow (A++B). It is urged in the direction of the arrow (B) by the elastic force. At this time, the end of the spherical member 100a in the direction of the arrow (B) is pushed away from the inner surface of the front cabinet 97a in the direction of the arrow (B) in the diagram.
It protrudes in direction B. On the other hand, in a portion of the frame 102a of the speaker body 101a corresponding to the spherical member 100a, the depth direction is set in the direction of the arrow (G) in the figure, and a substantially truncated cone-shaped concave portion 103a has a larger diameter on the opening surface side. It is set up like this. Although not shown, the speaker main body 101a is supported by a plurality of speaker support pillars provided on the rear plate of the rear cabinet. In such a configuration, due to manufacturing precision of the parts of the stereo radio cassette, even if a positional shift occurs between the front end of the speaker body 101a attached to the rear cabinet and the buff-full surface 98a of the front cabinet 97a, the front When the cabinet 97a is assembled into the rear cabinet, the front end of the speaker main body 101a can be reliably accommodated in the speaker accommodating portion.

That is, in FIG. b, for example, the speaker body 101
If the speaker body 101a is attached to the rear cabinet with the speaker body 101a positioned in the direction of the arrow (G) than the normal position, the inclined surface of the concave portion 103a of the speaker body 101a will be aligned with the spherical member 10.
0a, and the speaker body 101a is in contact with the illustrated arrow (F).
The positional deviation in the direction is corrected, and the spherical member 100
a is pushed by the speaker body 101a and moves in the direction of the arrow (A) shown in the figure. Therefore, the front end of the Spier main body 101a uniformly abuts against the buff-full surface 98a. FIG. 22 shows a modification of the positioning means, and the structure of the speaker accommodating portion of the front cabinet 98b is approximately the same as that in FIG. A recessed portion 99b is provided instead.

That is, the concave portion 99b is formed in a substantially truncated conical shape with the depth direction set, for example, in the direction of arrow (4) in the figure, and the diameter is larger on the opening surface side. And this concave portion 9
9b has a shape similar to that of the spherical member 100a shown in FIG.
A pair are provided on the top, bottom, left and right sides of b. On the other hand, in the frame 101b of the speaker body 100b,
For example, a hemispherical protrusion 102b protruding in the direction of arrow (A) is provided at a portion corresponding to the recessed portion 99b.

In such a configuration, even if the speaker body 100b is attached at a position deviated from the normal attachment position, the protrusion 102b is guided by the inclined surface of the concave portion 99b, so that the front end of the speaker body 100b is reliably attached. can be accommodated in the speaker housing.

FIG. 23 shows still another modification, in which a protrusion 99c projecting in the direction of the arrow (g) in the figure is formed integrally with the buffle surface 98c of the front cabinet 97c, for example, by molding.

This protrusion 99c has, for example, a substantially truncated conical shape, and is provided so that the small diameter portion is located in the direction of arrow (B) in the figure. For example, a protrusion with such a shape can also be used as a buttful surface 98.
A pair are provided on the top, bottom, left and right of c. Z1 On the other hand, in the frame 101c of the speaker body 100c, a hole 102c that engages with the projection 99c is provided at a portion corresponding to the projection 99c.

In such a configuration, the hole 102c engages with the protrusion 99c and is guided by the inclined surface of the speaker body, thereby correcting the misalignment of the speaker body and ensuring that the front end of the speaker body 100c is placed in the speaker accommodating portion. can be accommodated.
FIG. 24 has a configuration substantially opposite to that of FIG. 21 described above.

That is, a projection 98d projecting in the direction of arrow (B) in the figure is provided in the speaker housing portion of the front cabinet 97d, and a truncated conical hole 99d is formed at the end of the projection 98d in the direction of the projection so that the opening side has a larger diameter. do. On the other hand, the illustrated arrow (A) direction end of the speaker support column 100d is
A hole 101d whose depth direction is set in the l direction is formed, and a spherical member 103d is provided in the hole 101d so as to be slidable in the direction of the arrow (AeB) shown in the drawing, with, for example, a spring 102d interposed therebetween. This spherical member 103d is normally positioned in the direction of arrow (A) in the figure by the elastic force of the spring 102d, and the speaker body 104d is shaped into a spherical shape by a hole provided in a portion of the frame 105d corresponding to the spherical member 103d. It is attached to the speaker support column 100d so as to be engaged with the member 103d. In such a configuration, the spherical member 103d is guided by the inclined surface of the hole 99d, thereby correcting the displacement of the speaker body 104d, and the Spier body 104d is reliably accommodated in the speaker housing portion.

In this way, the misalignment between the outer periphery of the front end of the speaker body disposed in the rear cabinet and the speaker accommodating portion of the front cabinet is automatically corrected when the front cabinet and rear cabinet are combined. The following effects can be obtained by adopting a configuration in which such a positioning means is provided.

In other words, the front end of the speaker body can be automatically accommodated in the speaker accommodating portion of the front cabinet by a one-touch operation of combining the front cabinet with the rear cabinet, which is very convenient. It also has the advantage of having a simple configuration and being able to be implemented at low cost. Note that the positioning means that automatically corrects the positional deviation between the front end of the speaker body and the speaker housing ZZ section when the front cabinet and rear cabinet are combined is not limited to the above configuration, and may be used in other ways. Of course, this is also possible.

Next, a speaker mounting device characterized by the arrangement of speaker support columns will be described.

In FIG. 1, the rear plate 11a of the rear cabinet 11 is
four speaker support pillars 17 on each side of the left and right sides,
The case where 18 is provided has been explained. However, in a configuration such as this stereo radio cassette in which no other mechanism exists behind the speaker bodies 13, 14, the speaker support columns can be freely arranged, so for example, as shown in FIGS. 25 to 28 below. The arrangement shown is possible. That is,
What is shown in FIG. 25a is the rear panel 106 of the rear cabinet.
For example, support column 1 of mid-bass speaker body 107a is shown in a.
09a and the supporting column 110 of the treble Spier main body 108a
This is a configuration in which four pieces of each a are arranged, for example, in the downward direction of the road of the rear plate 106a (in the direction of the arrow (G++H) in the figure).

However, in the figure, two support columns 109a and 110a are each shown, and the protrusion lengths of the support columns 109a and 110a are set to be different. Also, the rear plate 10
For example, four supports 112a of the transformer 111a are provided above the transformer 6a. However, only two are shown in the figure. In such a configuration, the speaker support pillars 109a and 110 are formed in advance when forming the rear cabinet.
Both a are integrally formed on the rear cabinet by, for example, molding, and, for example, both speaker bodies 107a
, 108a, each speaker body 107a, 108a is connected to a corresponding speaker support column 109a, 110a.
Attach to.

In addition, in a model that uses only the speaker body 107a, the speaker body 107a is connected to the speaker support column 109a.
It is also possible to use the speaker force support column 110a as it is without attaching anything to it. In this way, the rear plate 106a of the rear cabinet
By providing the speaker support pillars 109a and 110a in the back panel, this rear cabinet can be used in common for different types of stereo radio cassettes, which is rational in terms of manufacturing and management of the rear cabinet. The projection length of the support column 109a' for the speaker body 107a and the support column 110a' for the speaker body 108a are shown in FIG.
The only difference from the structure shown in FIG. 1A is that the protrusion lengths of the two are made substantially the same, and the other structures are substantially the same.

What is shown in FIG. 26a is the rear panel 106 of the rear cabinet.
This is a configuration in which six support columns 108b for the speaker body 107b are provided in b (however, only three are shown in the figure).

That is, as shown in Figure b, the rear plate 1 of the rear cabinet
The configuration is such that two rows of three wires are provided at a predetermined distance in the vertical direction (direction of arrow (GeH) in the figure) of 06b. In such a configuration, if it is desired to attach the speaker body 107b relatively lower in the stereo radio cassette, the speaker body 107b is attached in the state shown in 7 in FIG.

Conversely, if you want to install it on the upper side, install it as shown in step 4. By providing a plurality of speaker support columns 108b on the rear panel 106b of the rear cabinet as described above, it is possible to secure a plurality of different mounting positions for the speakers.

Therefore, by changing the speaker mounting position in accordance with the shape of the stereo radio cassette, which changes depending on the specifications and purpose, the rear cabinet configured as described above can be used in common with different models of stereo radio cassettes. This is reasonable in terms of manufacturing and management of the rear cabinet. What is shown in FIG. 27 is based on the same concept as in FIG.
6c, the nine speaker support columns 108c are indicated by arrows (G
This configuration has three rows of three wires in each direction.

In such a configuration, the speaker main body 107c can be installed in four locations (7(3)O1), and the above-mentioned rear cabinet can be installed in many more models than the one described in FIG. 26 above. Can be commonly used for stereo radio cassettes. The speaker shown in FIG. 28 is constructed so that both the speaker main body 107d and the speaker main body 108d can each have a plurality of different mounting positions.

In this case, the support column 109d for the speaker body 107d
For example, if they are arranged as shown in FIGS. 26A and 26b, two different speaker mounting positions can be secured with respect to the speaker body 107d, and if they are arranged as shown in FIG. 27, four different speaker mounting positions can be secured. The speaker mounting position can be secured. The same applies to the support column 110d of the speaker main body 108d. In the rear cabinet configured in this way, different types of speaker bodies 1 can be installed in accordance with the configuration of the stereo radio cassette, which changes depending on the specifications and purpose.
07d and 108d can be attached selectively or both together.

Also, in each speaker body 107d, 108d,
Since its mounting position can be changed, the rear cabinet can be used in common with more different types of stereo radio cassettes than with the previous configuration. In the above description, the speaker support pillars are arranged in the vertical direction of the rear plate of the rear cabinet, but it goes without saying that they may be arranged in the horizontal direction, for example.

In this way, by providing a plurality of speaker support pillars on the rear plate of the rear cabinet, and attaching the speaker body to a predetermined plurality of speaker support pillars selected from among the plurality of speaker support pillars, Since the type of speaker body to be attached and the mounting position can be changed as appropriate, a predetermined type of rear cabinet can be used in common for different models of stereo radio cassettes, and this makes it easier to manufacture and manage the rear cabinet. and is reasonable. Regarding this point, conventional configurations have been such that the speaker body is attached to the front cabinet, so once the type of speaker body, number of speaker bodies, and mounting position are decided, even if you want to change the design of the front cabinet, for example, you cannot change this. The drawback was that it was difficult to change.

Next, the component mounting device will be explained.

As in the stereo radio cassette explained in FIG. The shape, size, location, etc. of the support column can be freely set.

For example, when the size of the support column is increased, a plurality of locations for supporting the mechanical part can be set on such a support column.

FIG. 29 shows a component mounting device having a support column provided with a plurality of support points, and this component mounting device will be described in detail below using the mechanism section 12 as a component.

Note that the same parts as in FIG. 1 are given the same reference numerals. First, the same figure a
Reference numerals 113, 114, 115, and 116 are mechanical support pillars of the force set tape recorder which are integrally formed with the rear plate 11a of the rear cabinet 11 (see FIG. 1B) by, for example, molding.

These support columns 113, 114, 115, and 116 are arranged, for example, in two rows of two in the vertical direction of the rear cabinet approximately at the center of the rear plate 11a. Also, as shown in Figure b, the front of the rear cabinet 11, that is, the arrow
For example, it is formed into a cylindrical body that protrudes in the direction. The end faces of the support columns 113, 114, 115, and 116 in the protruding direction each have a plurality of screw holes 117, 118 each having a depth direction set in the direction of the arrow (B) as screws, respectively.
119 and 120 are provided. For example, the support column 11
3 and 114 have 4 pieces each, and support columns 115 and 116
There are five each. In the mechanism section 12 that is attached to the protruding direction ends of the support columns 113, 114, 115, 116 in which the plurality of screw holes 117, 118, 119, 120 are formed, the support columns 113, 114 , 115, 116, the plurality of screw holes 117, 118, 119, 12, respectively.
A screw insertion hole corresponding to any one of 0 is provided.

For example, in the mechanism section 12 shown in FIG.
A screw insertion hole 121 whose screw insertion direction and opening coincide with any one of the plurality of screw holes 117 is provided in a portion corresponding to 13, and the screw 123 is inserted through this screw insertion hole 121 into the corresponding screw. It is screwed into the hole 117.

In addition, a plurality of screw holes 1 are provided in a portion corresponding to the support column 115.
A screw insertion hole 122 having the same screw insertion direction and opening is provided in one of the screw insertion holes 19.
The screw 124 is screwed into the corresponding screw hole 119 via the screw 22. Note that, although not shown, a plurality of screw holes 118, 1 are similarly provided in portions corresponding to the support columns 114, 116.
A screw insertion hole whose screw insertion direction and opening coincide with each other is provided in one of the screw holes 20 , and the screw is screwed into the corresponding screw hole 118 , 120 through this screw insertion hole. Installation is done. In this way, the rear plate 11a of the rear cabinet 11 has a plurality of screw holes 117, 118,
Support columns 113, 114, 11 with 119, 120
5 and 116, it is possible to secure multiple support points for the mechanism part, and the support columns 113, 114, 11
5, 116 can also be attached to a mechanism section of a different type from the mechanism section 12 shown in FIG.

Therefore, as shown in the same figure, the support columns 113, 114, 11
The rear cabinet provided with 5 and 116 can be used in common for a plurality of stereo radio cassettes of different models, and is rational in terms of manufacturing and management of the rear cabinet. It should be noted that the present invention is not limited to the above embodiments, and can be modified in various ways without departing from the gist of the invention.

For example, although the previous embodiment has been described using a stereo radio cassette, the present invention is not limited to this, and may be a power set tape recorder such as a monaural or 2-way system, or a power set tape recorder not equipped with a radio receiver. Of course, 1 is also good.

As described above, according to the present invention, since front operation is possible, operability can be improved, and functions can be improved without increasing the size of the main body, and assembly, repair, inspection, etc. are easy, and manufacturing costs can be reduced. It is possible to provide a force setting tape recorder that can reduce vibrations, improve sound quality, and prevent vibrations of the printed wiring board.
