Description

Television with remote pickup function

Technical Field

The application relates to the field of household appliances, in particular to a television with a remote pickup function.

Background

With the upgrading of consumption demands and the continuous innovation of technologies, the intellectualization of home appliances is an irresistible trend. Because the intellectualization of the household appliances is an irreversible trend, many household appliance enterprises are in layout intellectualization, and the intellectualization of the color TV as an electronic product is obviously faster. Therefore, the remote sound pickup module capable of performing remote voice recognition and interaction becomes a standard configuration of the intelligent or smart flat-panel television.

The development of the ultra-thin and ultra-narrow form of the television product requires that the integral form of the appearance cannot be damaged while the functional requirements of users are met, so that the components such as keys, indicator lamps, remote control lamps and remote pickup of the whole television cannot find a proper installation space in the whole television. The keys, indicator lights, remote control lights and remote pickup of the television are all components that the user needs to pay close attention to and interact with, and therefore a clear display is needed at a location that is easily visible on the front of the television. The traditional television product has sufficient space, and generally the function is realized by arranging an indicator lamp printed board on the front surface of the front shell at the left lower corner and the right lower corner of the whole television. The ultra-thin and ultra-narrow products at the middle and high ends are required to be extremely frame-caused and required to be loaded with necessary functional components due to the appearance, so that the whole machine of the ultra-thin and ultra-narrow products is required to find a proper structure to solve the installation problem of the indicator lamp so as to meet the balance of functional requirements and appearance integral feeling and meet the requirement of product competitiveness development.

In the process of mounting the above-mentioned components, how to mount the sound pickup box body under the condition that the television is ultra-thin and ultra-narrow becomes more and more important. Referring to fig. 1 to 5, fig. 1 is a schematic structural diagram of a television with remote sound pickup function in the prior art; FIG. 1-1 is an enlarged view of a portion A of the television set of FIG. 1; fig. 2 is a schematic view of the assembly of the front housing and the sound-collecting box body of the television set in fig. 1; FIG. 3 is an enlarged view of a portion A of FIG. 2; FIG. 4 is a front plan view of the structure of FIG. 2; fig. 5 is a sectional view taken along the line a-a in fig. 4.

In the related art, as shown in fig. 1 and 1-1, a tv set includes a front case 110, a rear case 120, a COF module 130, and a sound-collecting box body 140. The sound-collecting case 140 includes a chassis member 141, and other components of the sound-collecting case 140, such as a PCB, are mounted in the chassis member 141.

As shown in fig. 2 and 3, the bottom of the chassis 141 of the sound-collecting box body 140 is provided with two U-shaped slots 141a, and correspondingly, the front shell 110 is provided with slots 141a and slots ribs 111 formed by notches, and the slots 141a are clamped into the slots 141a and the slots ribs 111, so as to complete corresponding position limitation.

In addition, as shown in fig. 2 and 3, the upper end of the chassis 141 is provided with a whole set of stud retaining edge 141b with a certain height, and the corresponding rear housing 120 is provided with two U-shaped grooves, which are respectively formed by combining the inner retaining rib 121 and the outer inserting tongue retaining rib 122 on the rear housing 120, and after the rear housing 120 rotates in, the U-shaped grooves are clamped into the stud retaining edge 141b of the chassis 141, thereby finally completing the fixed connection of the sound-collecting box body 140.

There are two defects in the above-mentioned spacing scheme of pickup box body 140:

first, considering different sizes of televisions requires the cartridge body 140 module to be universal and compatible with different panel resources. As shown in fig. 5, the upper sidewall 141c of the insertion groove 141a of the chassis member 141 protrudes into the interior of the front case 110, thereby occupying the interior space of the front case 110. In fig. 1, when a television set of another size is mounted, the upper side wall 141c of the insertion groove 141a may interfere with the COF module 130, so that it is not versatile and the chassis 141 of the module has to be newly designed.

Secondly, the fixed connection of the pickup case 140 is simultaneously completed by the front case 110 and the rear case 120, respectively, and there is a skew before the rear case 120 is not assembled, so that it is convenient to assemble the rear case 120 by holding it in place. The condition can lead to the extension of the assembling time, reduce the assembling efficiency and improve the assembling cost.

The above describes problems in the mounting of the pickup case 140 to the front case 110 and the rear case 120. In addition, the mounting of the internal structure of the sound collection case 140 has certain problems. The remote pickup module comprises a chassis part 141, a light guide part, a rubber part, a PCB (printed Circuit Board), a pressing plate bracket and the like, wherein the parts are fixedly installed by adopting a mode of bonding by screws or glue and the like. However, when the conventional mounting methods of screws, tape bonding or glue coating bonding are adopted, the mounting is complex, the operation is difficult, the mounting is not easy to disassemble, more inconvenience is brought to production and maintenance, and meanwhile, the structure of parts is complex, the subsequent manufacturing and processing are complex, and a large amount of cost is increased.

Detailed Description

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following examples do not represent all embodiments consistent with the present application. But merely as exemplifications of systems and methods consistent with certain aspects of the application, as recited in the claims.

In an embodiment, please refer to fig. 6, and fig. 6 is a schematic structural diagram of a television set according to an embodiment of the present application. The television comprises a front shell, a pickup box body and a rear shell. Fig. 7 and 8 can be referred to, and fig. 7 is an exploded view of the structure of the sound-collecting box body of the television set in fig. 6; fig. 8 is a top view of the structure of fig. 7 assembled together.

As shown in fig. 7 and 8, in one embodiment, the pickup case 400 includes a chassis member 410, and the chassis member 410 is provided with a mounting cavity 411; a pressing plate bracket, a laminated PCB and a light guide part 420 are arranged in the mounting cavity 411; the light guide 420 is disposed at the front side of the PCB, and the pressing plate bracket is disposed at the rear side of the PCB.

Here, front, rear, left, right, upper, and lower in the description refer to: in fig. 8, the sound pickup case 400 in a top view is taken as a positioning reference, and a downward direction in a paper plane is taken as a front side and an upward direction is taken as a rear side; on the basis, the left direction and the right direction are the left side and the right side; on this basis, in the direction perpendicular to the plane of the paper, there are upper and lower sides, respectively. Accordingly, in this context, the front wall, the rear wall, and the like, with the directional orientation, are all defined in this description.

In addition, in other parts of the text, unless otherwise specified, the meanings of front, rear, left, right, upper and lower are to be determined in accordance with the description.

A first limiting part and a second limiting part for limiting left and right are arranged on two sides of the installation cavity 411, and the laminated PCB 440 and the light guide member 420 are clamped between the first limiting part and the second limiting part; it should be noted that, as shown in fig. 7 and 8, the chassis 410 includes a mounting cavity 411, the mounting cavity 411 includes a front mounting cavity wall 411a, a rear mounting cavity wall, and left and right side mounting cavity side walls 411b, and the rear mounting cavity wall includes a horizontal portion 411d and an inclined portion 411 e. The rear wall further includes two parts, a lateral straight part 411d and an inclined part 411 e. Thus, the front wall, the two side walls, the two inclined portions 411e and the horizontal portion 411d enclose the mounting cavity 411 of the chassis member 410.

The pressing plate bracket 450 is provided with a third limiting part; the third limiting part abuts against the PCB 440, and the light guide member 420 abuts against the front wall of the mounting cavity 411, so that the front and rear limitation of the PCB 440 and the light guide member 420 is realized.

In the above embodiment, the sound-collecting box 400 of the tv set includes the chassis 410, the pressing plate holder 450, the PCB 440, the light guide 420, and the like are disposed in the mounting cavity 411 of the chassis 410, and the PCB 440 and the light guide 420 are stacked, and further, the rubber 430 is disposed between the PCB 440 and the light guide 420, the rubber 430, and the PCB 440 are sequentially disposed from the front wall of the chassis 410. In the installation cavity 411 of the chassis 410, a first limit portion and a second limit portion are respectively arranged on the left and the right, and the PCB 440 and the light guide member 420 which are correspondingly stacked are clamped between the first limit portion and the second limit portion. It should be noted that the mounting structure is clamped, not screwed or glued, and is clamped between the two limiting parts in a certain elastic deformation manner, so that the light guide member 420, the rubber member 430 and the PCB 440 are limited in the left-right direction.

In addition, in relation to the front-rear direction restriction of the three components, the light guide member 420 is an outermost component, and abuts against the inner side wall of the front wall of the mounting cavity 411 of the chassis member 410, thereby realizing the restriction of one degree of freedom. Then, the pressing plate bracket 450 is located at the rear side of the PCB 440, and is provided thereon with a third limiting portion, which abuts against the PCB 440, thereby achieving the limiting of another degree of freedom. And finally, the limit of the three parts in front and back two degrees of freedom is realized.

In summary, the light guide member 420, the rubber member 430, and the PCB 440 are mounted and positioned so as to be locked or abutted to each other, thereby achieving the position limitation in the four degrees of freedom in the front, rear, left, and right directions. The limiting structure avoids mounting modes such as screws or gluing, the complexity of an internal mounting structure can be reduced, the assembly cost is reduced, the mounting and the like are easy to disassemble, and the convenience of production and maintenance is obviously improved.

It should be noted that, in the above embodiments, specific structures of the first position-limiting portion, the second position-limiting portion and the third position-limiting portion are not limited. As an example, as shown in fig. 7, the first position-limiting portion may be a first position-limiting rib plate 412a, and the second position-limiting portion may be a second position-limiting rib plate 412 b.

Specifically, as shown in fig. 7, the two stop ribs are formed by protruding from the bottom wall of the mounting structure. In a specific forming mode, the two limiting rib plates may be formed by injection molding with the chassis piece 410, and may be fixed at a later stage, for example, by welding or other methods, which is not limited in the present application. Obviously, the mode of clamping the two rib plate clamping positions can conveniently limit the light guide part 420, the rubber part 430 and the PCB 440 in the left-right direction, and has simple structure and low assembly cost.

Further, in the above-described embodiment, it is possible to further improve. Specifically, as shown in fig. 7, a first guiding rib plate 413a may be disposed on an inner side wall of the first limiting rib plate 412a, and a second guiding rib plate 413b may be disposed on an inner side wall of the second limiting portion; as shown in fig. 7, first guide rib plate 413a is a plate member formed by projecting from the inner side wall of first stopper rib plate 412a, and second guide rib plate 413b is another plate member formed by projecting from the inner side wall of second stopper rib plate 412 b.

Correspondingly, as shown in fig. 7, one end of the stacked PCB 440 and the light guide 420 is provided with a first guide slot 421a matching with the first guide rib 413a, and the other end thereof is provided with a second guide slot 421b matching with the second guide rib 413 b.

It should be noted that, two ends of the PCB 440 are respectively provided with a first guiding slot 421a and a second guiding slot 421 b; correspondingly, the two ends of the light guide member 420 are also respectively provided with a first guiding slot 421a and a second guiding slot 421b, and the sizes are the same. As shown in fig. 7, when the two are overlapped, the first guide slot 421a at one end of the PCB 440 and the first guide slot 421a at one end of the light guide 420 are overlapped, and the second guide slot 421b at the other end of the PCB 440 and the second guide slot 421a at the other end of the light guide 420 are also overlapped and respectively clamped into the corresponding first guide rib 413a and the corresponding second guide rib 413 b.

In the above embodiment, the specific structures of the pressing plate bracket 450 and the third limiting portion may be specifically designed. For example, referring to fig. 11, 12 and 13, fig. 11 is a schematic structural view of a pressure plate holder of the sound pickup box body in fig. 7; FIG. 12 is a top view of the platen bracket of FIG. 11; fig. 13 is a sectional view taken along the line a-a in fig. 12.

In this embodiment, as shown in fig. 11, the platen bracket 450 includes a bracket body 451 fixed to the bottom wall of the mounting chamber 411; the third position-limiting part extends from the front wall of the bracket body 451 and abuts against the third position-limiting rib plate 452a on the PCB 440. As shown in fig. 11, the holder body 451, which is the body of the platen holder 450, is a generally rectangular parallelepiped structure, which primarily functions to provide a corresponding mounting structure, thereby enabling the platen holder 450 to be secured to the bottom wall of the mounting chamber 411, for which specific securing structure we discuss below.

Specifically, a plate may be connected to the front wall of the bracket body 451, and the front side of the plate is bent upward to form the third limiting rib 452 a. The bending angle of the third limiting rib plate 452a enables the third limiting rib plate to be attached to the opposite contact surface of the PCB 440, so that the reliability of contact limiting is ensured.

As an example, as shown in fig. 11 and 12, a rib supporting portion 452 is provided on the front wall of the bracket body 451, and an outer edge portion of the rib supporting portion 452 is bent upward to form a third limiting rib 452 a. The structural design can very conveniently realize the processing and forming of the third limiting rib plate 452a, and has simple structure and lower cost.

That is, the plate member is defined as a rib support portion 452, and the rib support portion 452 is attached to the front wall of the bracket body 451. The rib supporting portion 452 may be connected to the bracket body 451 by welding or other connection methods, or may be integrally machined with the bracket body 451 as an integral material, which is not limited in the present application.

Further, since the PCB is long in the left-right direction, the third stopper rib 452a needs to have a sufficient length in the left-right direction for performing the abutment stopper in order to improve the reliability of the abutment stopper. Alternatively, the third rib stopper 452a may have more than one, for example, two, although it does not have a sufficient length. In view of this, as shown in fig. 11 and 13, the rib support part 452 extends from the right side of the holder body 451 (i.e., the side of the light guide 420 where the remote control pole 422 is located in fig. 7) to form a support positioning part 453; the outer edge of the support positioning part 453 is bent upwards to form a third limiting rib 452 a. Obviously, the structure can obviously improve the abutting limiting length of the third limiting rib plate 452a, so that the abutting limiting reliability is improved.

It should be noted that the rib supporting portion 452 and the supporting and positioning portion 453 may be integrally formed in one plate, or may be separate plates, and are connected together by welding or other connection methods, which is not limited in this application.

In the above structure, as shown in fig. 7 and 8, when a viewer of the tv presses a button on the right side of the tv, such as a tv switch or other buttons, a large force is applied to the light guide 420 and the right end of the PCB 440, and is finally transmitted to the third rib portion 452a of the supporting and positioning portion 453 through the transmission of the force. Since there is no stopper behind the third stopper rib 452a, the third stopper rib 452a is easily elastically deformed, which reduces the reliability of abutment stopper.

In view of this, as shown in fig. 7 and 8, a fourth stopper is further provided on the bottom wall of the mounting chamber 411 at the rear side of the support and positioning portion 453, and the fourth stopper abuts against the support and positioning portion 453. The fourth limiting part limits the position of the supporting and positioning part 453 and the third limiting rib plate 452a thereon, so that elastic deformation of the supporting and positioning part is prevented, and the abutting and limiting reliability of the supporting and positioning part is improved.

Specifically, as shown in fig. 7 and 8, the fourth stopper is an L-shaped fourth stopper rib 414, and the bent portion of the L-shaped stopper rib abuts against the support positioning portion 453. The fourth limiting rib plate 414 adopts an L-shaped structure, and can have a larger fixing and connecting force, thereby realizing a larger limiting force.

In addition, as shown in fig. 11, the number of the third stop webs 452a is two, and the web support portion 452 further includes a button protection sleeve 455 connected between the two third stop webs 452 a. As shown in fig. 11, the button protection cover 455 has a square body structure and is hollow inside, so that the switch button 446 on the PCB 440 can be inserted into the button protection cover 455 when the pressing plate bracket 450 abuts against the PCB 440.

In any of the above embodiments, further modifications can be made to specifically design the manner in which the platen bracket 450 is secured. Referring to fig. 9 and 10, fig. 9 is a schematic structural view of a chassis member of the pickup cartridge of fig. 7; fig. 10 is a bottom view of the chassis member of fig. 9.

For example, as shown in fig. 7, 8 and 9, a first buckle 415 is respectively arranged on the bottom wall of the mounting cavity 411 at both sides of the bracket body 451; the holder body 451 is fixed in the mounting chamber 411 by the first catch 415. It should be noted that the first buckle 415 can be a hook structure and has a certain elasticity, and when the bracket body 451 is placed between the two, the hook of the first buckle 415 is pressed by force, so that the upper end surfaces of the two sides of the bracket body 451 can be clamped by the hook of the first buckle, the bracket body 451 is fixed, and the limitation of the pressure plate bracket 450 in the left-right direction is realized.

Further, in order to limit the pressure plate holder 450 in the front-rear direction, as shown in fig. 7, 8 and 9, a positioning post protrudes from the bottom wall of the mounting cavity 411, and as shown in fig. 11, 12 and 13, the holder body 451 is provided with a positioning hole 454 matched with the positioning post.

The technical scheme in the above embodiment is developed around the installation limit relationship of the internal components of the sound pickup box body. In addition, the present application also provides an example of how the sound-pickup case as a whole is mounted in a spacing relationship with other parts of the television. As described in the background of the present description:

there are two defects in the spacing scheme of pickup box body among the prior art:

first, considering different sizes of televisions requires the universal cartridge body module and compatibility with different panel resources. As shown in fig. 5, the upper side wall of the socket of the chassis member protrudes into the interior of the front case, thereby occupying the interior space of the front case. In fig. 1, when a television set of other size is mounted, the upper side wall of the slot may interfere with the COF module, so that it is not universal, and the chassis of the module has to be redesigned.

Secondly, the fixed connection of the pickup box body is finished by the front shell and the rear shell simultaneously, and the rear shell is not assembled and is inclined, so that the pickup box body is convenient to be installed in a position by hand. The condition can lead to the extension of the assembling time, reduce the assembling efficiency and improve the assembling cost.

In view of the above, in one embodiment, the present application provides a television with remote sound pickup function, specifically please refer to fig. 6, fig. 9, fig. 10, fig. 22, fig. 23, fig. 24, fig. 25, and fig. 26, where fig. 22 is a partially enlarged view of a portion a of the television in fig. 6; fig. 23 is a front view of the pickup box and front housing of the television of fig. 6; FIG. 24 is a sectional view taken along line A-A of FIG. 23; FIG. 25 is a sectional view taken in the direction B-B in FIG. 23; fig. 26 is a sectional view taken along the direction C-C in fig. 23.

In such an embodiment, as shown in fig. 6, the television set includes a front case 200 and a sound-pickup box body 400. As shown in fig. 9, the cartridge body 400 includes a chassis member 410, and the chassis member 410 is attached to the front case 200. On this basis, as shown in fig. 24, 25 and 26, the front case 200 includes a horizontal portion 210 and a vertical portion 220, and further, a front wall of the chassis member 410 is connected to the horizontal portion 210.

As shown in fig. 23, 24, 25 and 26, the front housing 200 is a bent plate having an L-shaped outer shape, and includes a horizontal portion 210 and a vertical portion 220; the vertical portion 220 is in a plane parallel to the plane of the tv panel, and the horizontal portion 210 is perpendicular or substantially perpendicular to the plane of the tv panel.

On the basis of the above structure, as shown in fig. 24, a limiting part protrudes from the bottom wall of the outer side end of the horizontal part 210, and the limiting part is provided with a slot 231 with an opening facing the inner side; the front wall of the chassis member 410 is connected to an outwardly bent insertion tongue as shown in fig. 9, and the insertion tongue is inserted into the insertion groove 231 as shown in fig. 24.

In the above structure, as shown in fig. 9, the tongue is provided above the front wall of the chassis member 410 as a plate member and is formed by being bent outward. To facilitate insertion of the tongue, as shown in fig. 9, a portion of the wall surface of the front wall of the chassis member 410 below the tongue is cut away to facilitate insertion of the tongue into the slot 231.

As shown in fig. 24, a stopper is protruded from a lower portion of the horizontal portion 210 of the front case 200, and the stopper is provided to start the insertion groove 231. The tongue is inserted into the insertion groove 231. Meanwhile, the lower side wall of the slot 231 is also inserted into the groove body because the part where the inserting tongue is located is also bent, so that a mutually inserted structure is formed, and the reliability of connection, insertion and matching is further improved.

Compared with the mounting structure in the prior art, the above structural design is that the bottom plate 410 is connected and fixed below the horizontal portion 210 of the front housing 200, specifically, the insertion tongue thereof is inserted into the insertion groove 231 below the horizontal portion 210, so that the space above the horizontal portion 210 of the front housing 200 is not occupied, and therefore, when a television with other dimensions is mounted, the bottom plate 410 does not interfere with the COF module 500, thereby realizing general use, and thus, the bottom plate 410 does not need to be re-opened due to time and labor.

In the above-described embodiments, further improvements can be made. For example, as shown in fig. 9, second hooks 418 protrude from top surfaces of two side walls of the chassis 410, as shown in fig. 26, a locking groove 211 is recessed from a bottom surface of the horizontal portion 210, and the second hooks 418 are locked in the locking groove 211.

Specifically, as shown in fig. 9, the second buckle 418 is a square structure, and a groove for facilitating the second buckle 418 to be clamped in the clamping groove 211 is formed on the front wall of the square structure. This configuration may facilitate the second snap 418 to snap into the snap slot 211.

In the above technical solution, as shown in fig. 24, the bottom plate 410 cannot move to the right side in the figure any more by the fit limit of the insertion tongue and the insertion groove 231, thereby realizing the limit in the right direction. As shown in fig. 26, the chassis member 410 can not move leftward any more by the limit of the second latch 418 and the latching groove 211, so that the limit in the leftward direction is achieved. That is, the two mounting structures limit the position of the bottom plate 410 in the left-right direction. In addition, as can be seen from the specific structure in the figure, the two mounting structures also realize the limit of the chassis member 410 in the up-down direction. Therefore, the chassis 410 is well fixed and limited, and the sound-collecting box 400 is also well fixed and limited.

In the above-described limit structure, the fixing limit of the sound pickup case 400 is achieved only by the front case 200, and the rear case 300 is not required. Therefore, when the pickup cartridge 400 is installed, the fixed connection of the pickup cartridge body 400 is not required to be completed simultaneously by relying on the front shell 200 and the rear shell 300, so that the problem of skew before the rear shell 300 is not assembled is avoided, and the problem of convenient installation of the rear shell 300 due to the fact that Liu is not required to be held in place by hand is solved. Thus reducing assembly time and assembly cost.

In the above-described embodiments, further improvements can be made.

For example, as shown in fig. 9 and 10, the sidewall of the bottom plate 410 is provided with a vertically through isolation transverse groove 418 a; on the inner side of the second buckle 418, an isolation vertical groove 418b communicated with the isolation transverse groove 418a is opened on the side wall of the chassis member 410. The isolated lateral trenches 418a and isolated vertical trenches 418b function similarly to form a peninsula configuration. Due to the structure, the area where the second buckle 418 is located is easy to deform, so that the second buckle 418 is convenient to clamp in the clamping groove 211.

When the second buckle 418 is clamped with the clamping groove 211, in order to facilitate the position deformation of the area where the second buckle 418 is located, the following design may be made:

for example, in a semi-closed area enclosed by the isolation transverse grooves 418a and the isolation vertical grooves 418b, a boosting rib plate 418c protrudes from the bottom surface of the side wall of the chassis 410; the rib assist plate 418c is adjacent to the isolation cross trench 418a and is oriented in the same direction as the isolation cross trench 418 a. Obviously, the acting force is applied to the assisting rib plate 418c, so that the area where the second buckle 418 is located can be conveniently deformed, and the second buckle 418 and the clamping groove 211 can be very conveniently matched and disassembled.

In the above-described stopper structure, as shown in fig. 24, the inner side end of the horizontal part 210 of the front case 200 has a large length and protrudes more into the chassis member 410. Here, in order to improve the reliability of the upper and lower limit of the chassis 410, the following design may be made:

as shown in fig. 9, the two ends of the rear wall of the bottom plate 410 are provided with claws 419, and a gap is formed between the claws 419 and the side wall of the bottom plate 410, and as shown in fig. 24, the inner end of the horizontal portion 210 is engaged in the gap.

It should be noted that the latch 419 is provided on the top surface of the rear wall of the chassis 410 at the position where the inclined portion 411e is connected to the side wall. Also, since the side walls have a height lower than that of the rear wall, a certain gap is formed between the jaw 419 and the top surfaces of the side walls, and the gap needs to have a thickness greater than that of the horizontal portion 210 of the front case 200, thereby facilitating insertion of the inner end of the horizontal portion 210 of the front case 200.

In addition, in the above structure, a specific design may also be made for the specific shape of the chassis member 410. For example, as shown in fig. 9, the rear wall of the chassis member 410 has a trapezoidal configuration.

Specifically, as shown in fig. 9, the trapezoidal structure includes a horizontal portion 411d and inclined portions 411e connected to both ends of the horizontal portion 411 d; the inner end of the inclined portion 411e is inclined toward the inside of the chassis member 410 and connected to the horizontal straight portion 411 d; the outer end of the inclined portion 411e is connected to the side wall of the chassis member 410. That is, in the above structure, the horizontal straight portion 411d, the two inclined portions 411e, and the front wall of the chassis member 410 are formed in a trapezoidal structure. This structure provides some assembly space when the front case 200 and the rear case 300 of the chassis member 410 are assembled, thereby facilitating the assembly.
