## Background
CROSS-REFERENCE TO RELATED APPLICATION
The present application claims priority from Japanese Patent Application No. JP 2011-068159 filed in the Japanese Patent Office on Mar. 25, 2011, the entire content of which is incorporated herein by reference.
FIELD
The present technology relates to a technology relating to an in-vehicle audio apparatus, and more particularly, to a technology in which a pressing body moving in accordance with the moving position of a storage tray is arranged so as to stabilize the holding state of a music reproduction device inserted into the storage tray.
BACKGROUND
As an in-vehicle audio apparatus, there is an apparatus in which a mobile music reproducing device is inserted and housed in a storage tray, and music recorded in the music reproducing device is reproduced so as to be output from a speaker or the like arranged inside the vehicle in accordance with an operation performed from the outside.
In such an in-vehicle audio apparatus, since vibration occurs during the driving of the vehicle, it is necessary to suppress the effect of the vibration by holding the inserted music reproducing device in a stable state.
Thus, there is an in-vehicle audio apparatus in the related art in which a music reproducing device inserted into the inside of a casing is held by pressing it by using a rotatable pressing lever (for example, see JP-A-2000-332433, FIG. 17).
In the in-vehicle audio apparatus disclosed in JP-A-2000-332433, a casing is formed in the shape of a box open on the front side, and a first roller is supported at an upper portion of the front end of the casing, and a rotatable pressing lever is arranged inside the casing. The pressing lever is supported by the casing with its rear end portion configured as a point of support for rotation and can be rotatable so as to approximately vertically move the front end portion. In the front end portion of the pressing lever, a second roller is supported, and the pressing lever is maintained to be in a state in which the front side is lowered and is biased by a spring in a direction in which the front end portion is moved to the approximately lower side.
In the in-vehicle audio apparatus, a music reproducing device that has a main body and a lid body that is opened or closed by being rotated with respect to the main body is inserted and housed in the storage tray. As the music reproducing device is inserted into the casing from the front side in accordance with the movement of the storage tray, first, the first roller is slid in the lid body so as to rotate in a direction for closing the lid body. Thereafter, when the storage tray is moved further to the rear side, the music reproducing device is brought into contact with the second roller, and, by moving the music reproducing device so as to dive into the lower side of the pressing lever, the second roller is slid in the lid body, and the pressing lever is rotated in a direction opposite to the biased direction so as to close the lid body. The music reproducing device is pressed from the upper side by the second roller that is supported by the pressing lever having the front end portion biased in a direction for moving to the approximately lower side so as to be held inside the casing.
SUMMARY
However, the in-vehicle audio apparatus disclosed in JP-A-2000-332433 is configured such that, as the music reproducing device inserted into the inside of the lid body is brought into contact with the pressing lever in accordance with the movement of the storage tray, the music reproducing device is rotated in a direction opposite to the direction in which the pressing lever is biased, and the music reproducing device is pressed by the pressing lever.
Accordingly, there are problems in that only a music reproducing device having a size (thickness) that can be brought into contact with the pressing lever and being formed in the shape that can be allowed to dive into the lower side of the pressing lever can be pressed, there is tight restriction on the size and the shape of the music reproducing device that can be held, and the in-vehicle audio apparatus lacks versatility.
In addition, the music reproducing device is pressed by the second roller that can rotate, and thus, when the second roller rotates when vibration occurs, there is a concern that the state of holding the music reproducing device may be unstable.
Thus, it is desirable to increase the range of music reproducing devices that can be inserted into the storage tray so as to improve the versatility and stabilize the state of holding the music reproducing device.

In addition, the guide pins 29a and 29a are guided by the guide portions 10 and 14 of the guide rails 4 and 5, and the storage tray 22 is moved between a storing position and a drawing-out position.
The pressing body 30 is connected to the upper panel 6 through arm members 31 and 31 (see FIG. 5). The pressing body 30 is formed by vertically combining a connection plate 32 and a slide plate 33.
The connection plate 32 is formed in a rectangular shape, and, as illustrated in FIG. 15, in the connection plate 32, a spring arranging hole 32a that extends to the front and rear sides is formed at the center portion in the leftward and rightward directions. On the front side of the spring arranging hole 32a of the connection plate 32, a spring engaging protruded portion 32b is disposed.
In both left and right ends portions of the connection plate 32, horizontally-long insertion holes 32c, 32c, . . . are formed on the front and rear sides so as to be separated from each other. In the connection plate 32, plate-shaped support pieces 32d, 32d, . . . extending to the front and rear sides are disposed, and the support pieces 32d, 32d, . . . are positioned at the insertion holes 32c, 32c, . . . . The support pieces 32d, 32d, . . . have front edges and one side edge that are continuous from the opening edge of the insertion holes 32c, 32c, . . . . 
On the front end side of the upper face side of the connection plate 32, first connection grooves 32e and 32e are formed on the left and right sides so as to be separated from each other. The first connection grooves 32e and 32e are open to the upper side and the inner side and are formed so as to have mutually different lengths in the leftward and rightward directions.
On the rear end side of the upper face side of the connection plate 32, second connection grooves 32f and 32f are formed on the left and right sides so as to be separated from each other. The second connection grooves 32f and 32f are open to the upper side and the inner side and are formed so as to have mutually different lengths in the leftward and rightward directions.

On both left and right side faces of the connection plate 32, supporting shafts 32g and 32g that protrude to the outer side (lateral side) are disposed (see FIG. 15). The supporting shafts 32g and 32g are disposed at positions close to the front end of the connection plate 32. At the supporting shafts 32g and 32g, rollers 34 and 34 serving as cam engaging portions are supported so as to be rotatable.
In the lower face of the connection plate 32, shallow groove portions 32h and 32h that are open to the upper side and formed in a predetermined shape are formed on the front and rear sides so as to be separated from each other.
The slide plate 33 is formed in a rectangular shape, and the length thereof in the forward and backward directions is formed to be slightly shorter than that length of the connection plate 32 in the forward and backward directions. To the lower face of the slide plate 33, a cushion may be attached.
In the slide plate 33, as illustrated in FIG. 17, a spring supporting protruded portion 33a is disposed in an approximately center portion of the upper face.
In the slide plate 33, support pieces 33b, 33b, . . . that protrude to the upper side are disposed on both left and right end portions so as to be separated from each other. The support pieces 33b, 33b, . . . are formed in a letter “L” when viewed from the forward and backward directions.
The slide plate 33 has the support pieces 33b, 33b, . . . supported by the support pieces 32d, 32d, . . . and is configured to be slidable in the forward and backward directions with respect to the connection plate 32.
Between the spring supporting protruded portion 33a of the slide plate 33 and the spring engaging protruded portion 32b of the connection plate 32, a spring member 35 is supported (see FIG. 18). The slide plate 33 is biased to the front side with respect to the connection plate 32 by the spring member 35. The spring member 35 is arranged in the spring arranging hole 32a that is formed in the connection plate 32.
The arm members 31 and 31 arranged on the front and rear sides so as to be separated from each other between the upper panel 6 and the connection plate 32. Here, the number of the arm members 31 is arbitrary, and one arm member or three or more arm members may be arranged.
The arm member 31 is formed in a horizontally-long approximately rectangular shape, and, as illustrated in FIG. 19, includes a notch portion 31a that is open to the rear side in the center portion in the leftward and rightward directions. A center portion of the arm member 31 in the leftward and rightward directions is disposed as a spring receiving portion 31b. 
In the rear end portion of both left and right end portions of the arm member 31, first connecting protruded portions 36 and 36 are disposed, and the first connecting protruded portions 36 and 36 protrudes to the outer side (lateral side). In addition, in the front end portion of both left and right end portions of the arm member 31, second connecting protruded portions 37 and 37 are disposed, and the second connecting protruded portions 37 and 37 protrude to the outer side (lateral side).
The first connecting protruded portions 36 and 36 and the second connecting protruded portions 37 and 37 are formed to have an approximately oval-shape horizontal cross-section (see FIG. 20). The first connecting protruded portions 36 and 36, as illustrated in FIG. 16 have thicknesses T1 and T1 that are slightly smaller than the widths A, A, . . . of the first connection grooves 15e and 15e and the second connection grooves 15f and 15f of the upper panel 6, and the widths H1 and H1 thereof are formed to be larger than the widths A, A, . . . and slightly smaller than the diameters B and B. In addition, the second connecting protruded portions 37 and 37 have thicknesses T2 and T2 that are slightly smaller than the widths C, C, . . . of the first connection grooves 32e and 32e and the second connection grooves 32f and 32f of the connection plate 32, and the widths H2 and H2 are formed to be larger than the widths C, C, . . . and slightly smaller than the diameters D and D.
The first connecting protruded portions 36 and 36 are formed so as to have mutually different lengths in the leftward and rightward directions, and the second connecting protruded portions 37 and 37 are formed so as to have mutually different lengths in the leftward and rightward directions.
In the arm members 31 and 31, protruded portions 31c and 31c for standing are disposed at positions near the first connecting protruded portions 36 and 36 (see FIGS. 19 and 20).
The first connecting protruded portions 36 and 36 of one arm member 31 are inserted into the first connection grooves 15e and 15e of the upper panel 6, and the second connecting protruded portions 37 and 37 thereof are inserted into the first connection grooves 32e and 32e of the connection plate 32, whereby they are assembled with the upper panel 6 and the connection plate 32. In addition, the first connecting protruded portions 36 and 36 of the other arm member 31 are inserted into the second connection grooves 15f and 15f of the upper panel 6, and the second connecting protruded portions 37 and 37 thereof are inserted into the second connection grooves 32f and 32f of the connection plate 32, whereby they are assembled with the upper panel 6 and the connection plate 32.
At this time, as described above, the length of the first connecting protruded portions 36 and 36 and the length of the second connecting protruded portions 37 and 37 in the leftward and rightward directions are formed to be different from each other, and the lengths of the first connection grooves 15e and 15e, the lengths of the second connection grooves 15f and 15f, the lengths of the first connection grooves 32e and 32e, and the lengths of the second connection grooves 32f and 32f in the leftward and rightward directions are formed to be different from each other. Accordingly, attachment directions of the arm members 31 and 31 with respect to the upper panel 6 and the connection plate 32 are mistaken, and the attachment of the arm members 31 and 31 to the upper panel 6 and the connection plate 32 can be performed easily and appropriately.
In addition, the widths H1, H1, . . . of the first connecting protruded portions 36, 36, . . . are formed to be larger than the widths A, A, . . . of the first connection grooves 15e and 15e and the second connection grooves 15f and 15f. Accordingly, the first connecting protruded portions 36 and 36 can be inserted into the first connection grooves 15e and 15e and the second connection grooves 15f and 15f only in a predetermined direction (see FIG. 21).
Furthermore, as illustrated in FIG. 21, the assembly of the arm members 31 and 31 into the upper panel 6 is performed in a state in which the upper panel 6 is vertically reversed, and the upper panel 6 is located on the lower side of the arm members 31 and 31.
When the first connecting protruded portions 36, 36, . . . of the arm members 31 and 31 are inserted into the first connection grooves 15e and 15e and the second connection grooves 15f and 15f, the arm members 31 and 31 are in the state of being slightly inclined with respect to the vertical direction, and the protruded portions 31c and 31c for standing are brought into contact with the lower face of the upper panel 6 so as to allow the arm members 31 and 31 to stand (see FIG. 22).
Accordingly, the operation of inserting the second connecting protruded portions 37, 37, . . . into the first connection grooves 32e and 32e and the second connecting grooves 32f and 32f of the connection plate 32 can be performed in an easy manner.
At this time, the widths H2, H2, . . . of the second connecting protruded portions 37, 37, . . . are formed to be larger than the widths C, C, . . . of the first connection grooves 32e and 32e and the second connection grooves 32f and 32f. Accordingly, the second connecting protruded portions 37 and 37 can be inserted into the first connection grooves 32e and 32e and the second connection grooves 32f and 32f only in a predetermined direction (see FIG. 23).
Furthermore, as illustrated in FIG. 23, the assembly of the arm members 31 and 31 into the connection plate 32 is performed in a state in which the connection plate is vertically reversed, and the connection plate 32 is located on the upper side of the arm members 31 and 31.
In the state in which the upper panel 6 and the connection plate 32 are connected to each other through the arm members 31 and 31, the arm members 31 and 31 are rotated in a predetermined angle range. In other words, the arm members 31 and 31 are rotated in an inclining angle range θ (see FIG. 24) that is smaller than the angle at the time of being assembled into the upper panel 6 and the connection plate 32. In the range θ, the thickness T1, T1, . . . of the first connecting protruded portions 36, 36, . . . do not coincide with the widths A, A, . . . of the first connection grooves 15e and 15e and the second connection grooves 15f and 15f, and the thickness T2, T2, . . . of the second connecting protruded portions 37, 37, . . . do not coincide with the widths C, C, . . . of the first connection grooves 32e and 32e and the second connection grooves 32f and 32f. Accordingly, the arm members 31 and 31 are not dropped out of the upper panel 6 or the connection plate 32, and the operation of the in-vehicle audio apparatus 1 can be appropriately performed.
In the state in which the upper panel 6 and the connection plate 32 are connected to each other through the arm members 31 and 31, bias springs 38 and 38 are supported between the upper panel 6 and the arm members 31 and 31. Here, the number of the bias springs 38 is arbitrary, and one bias spring may be supported between the upper panel 6 and one arm member 31, or three or more bias springs may be disposed in a case where three or more arm members 31 are arranged.
The bias springs 38 and 38, for example, are torsion coil springs, coil parts 38a and 38a are supported by the first spring supporting shafts 15c and 15d of the upper panel 6, one end portions 38b and 38b are engaged with the lower face of the upper panel 6, and the other end portions 38b and 38b are engaged with the spring receiving portions 31b and 31b of the arm members 31 and 31.
Accordingly, a biasing force is applied to the arm members 31 and 31 by the bias springs 38 and 38 in a rotation direction for moving the front end portions to the approximately lower side, and the pressing body 30 is biased to be moved to the lower side of the upper panel 6 through the arm members 31 and 31.
One bias spring 38, in the state of being supported between the upper panel 6 and the arm member 31, is arranged at the first spring arranging hole 15a of the upper panel 6 and the notch portion 31a of the arm member 31. The other bias spring 38, in the state of being supported between the upper panel 6 and the arm member 31, is arranged at the second spring arranging hole 15b of the upper panel 6 and the notch portion 31a of the arm member 31.
Inside the in-vehicle audio apparatus 1 configured as described above, a music reproducing device 100 is housed. The music reproducing device 100 is inserted into the storage tray 22 or is taken out from the storage tray 22 in the state in which the storage tray 22 is positioned at the drawing-out position (see FIG. 2). The insertion of the music reproducing device 100 into the storage tray 22 is performed in a state in which a connector 101 is connected to the music reproducing device 100 (see FIG. 3).
When the music reproducing device 100 is inserted into the storage tray 22, and the storage tray 22 is moved up to the storing position, music recorded by the music reproducing device 100 can be reproduced so as to be output from a speaker or the like that is arranged inside the vehicle.
In addition, in a state in which the music reproducing device 100 is housed inside the in-vehicle audio apparatus 1, it may be configured such that, when the engine of the vehicle is stopped, light is emitted from a light emitting unit, which is not illustrated in the figure, disposed in the operation panel 21 as warning light, and a sound is output from a sound output unit, which is not illustrated in the figure, as a warning sound. Based on the emission of the warning light and the output of the warning sound, the music reproducing device 100 can be prevented from being forgotten to be taken out from the inside of the in-vehicle audio apparatus 1.
[Operation of In-Vehicle Audio Apparatus]
Hereinafter, the operation of the in-vehicle audio apparatus 1 performed when the storage tray 22 is moved will be described (see FIGS. 25 to 48). The storage tray 22 is moved between the drawing-out position (see FIGS. 2 and 3) located at a front-side moving end and the storing position (see FIG. 1) located at a rear-side moving end.
First, a state in which the storage tray 22 is located at the storing position will be described (see FIGS. 25 and 26).
When the storage tray 22 is located at the storing position, the guide pins 29a and 29a of the storage tray 22 are engaged with the holding portion 10c of the guide groove 10 of the guide rail 4 and the holding portion 14c of the guide groove 14 of the guide rail 5. At this time, the opening 19a of the front panel 19 is blocked by the front face portion 24 of the storage tray 22.
At the storing position, the rollers 34 and 34 supported by the connection plate 32 are engaged with the rear end portions of the descending portions 27a and 27a of the sliding cam portions 27 and 27 of the storage tray 22. Accordingly, the arm members 31 and 31 has the largest rotation angle with respect to the upper panel 6 and the connection plate 32 and is maintained at the moving end located on the lower side of the pressing body 30. At this time, the slide plate 33 is maintained at the moving end located on the front side by the biasing force of the spring member 35.
As the storage tray 22 is drawn out from the base body 3 and is moved toward the drawing-out position, the moving operation is started (see FIGS. 27 and 28).
In addition, the drawing-out of the storage tray 22 is performed by taking out the operation panel 21, for example, from the front panel 19 and gripping the gripping concave portion 24a formed in the front face portion 24. As above, since the gripping concave portion 24a is formed in the storage tray 22, the drawing-out of the storage tray 22 can be performed in an easy manner.
When the storage tray 22 is moved, the guide pins 29a and 29a pass the displacement portions 10b and 14b from the holding portions 10c and 14c of the guide grooves 10 and 14 and are engaged with the guiding portions 10a and 14a. At this time, since the guide pins 29a and 29a are engaged with the displacement portions 10b and 14b that are inclined with respect to the guiding portions 10a and 14a once, the feeling of the drawing-out of the storage tray 22 is delivered to a user's hand as a clicking feeling.
As the storage tray 22 is moved to the front side, the rollers 34 and 34 are rotated and are engaged with the ascending portions 27b and 27b from the descending portions 27a and 27a of the sliding cam portion 27. At this time, the rollers 34 and 34 are rotated with being pressed by the sliding cam portions 27 and 27 in accordance with the biasing forces of the bias springs 38 and 38 that are given through the connection plate 32.
Since the rollers 34 and 34 are engaged with the elevation portions 27b and 27b from the descending portions 27a and 27a, the pressing body 30 is moved to the upper side in resistance against the biasing forces of the bias springs 38 and 38, and the arm members 31 and 31 are rotated. At this time, since the pressing body 30 is moved in accompaniment with the rotation operations of the arm members 31 and 31, the pressing body 30 is moved to the upper side while being move to the front side to some extent.
When the storage tray 22 is further drawn out and moved to the front side, the rollers 34 and 34 are engaged with the upper end portions of the ascending portions 27b and 27b of the sliding cam portions 27 and 27 (see FIGS. 29 and 30). At this time, the guide pins 29a and 29a of the storage tray 22 are moved while facing the guiding portions 10a and 14a on the front side.
Since the roller 34 and 34 are engaged with the upper end portions of the ascending portions 27b and 27b, the pressing body 30 is moved further to the upper side in resistance against the biasing forces of the bias springs 38 and 38, and the arm members 31 and 31 are further rotated.
Subsequently, when the storage tray 22 is drawn out and moved to the front side, the rollers 34 and 34 are engaged with the front end portions of the elevation portions 27c and 27c from the ascending portions 27b and 27b of the sliding cam portions 27 and 27 (see FIGS. 31 and 32). At this time, the guide pins 29a and 29a of the storage tray 22 are moved while facing the guiding portions 10a and 14a on the front side.
Since the rollers 34 and 34 are engaged with the front end portions of the elevation portions 27c and 27c, the pressing body 30 is moved further to the upper side in resistance against the biasing forces of the bias springs 38 and 38 so as to arrive at the moving end located on the upper side, and the arm members 31 and 31 are rotated to be in an approximately horizontal state. At this time, the rollers 34 and 34 are inserted into and held by the insertion grooves 17 and 17 that are formed in the upper panel 6.
As the pressing body 30 is moved to the moving end located on the upper side, the rotation operations of the arm member 31 and 31 are stopped, and parts of the arm members 31 and 31 are inserted into the groove portions 15h and 15h formed in the upper panel 6 and the groove portions 32h and 32h formed in the connection plate 32. Accordingly, the arm members 31 and 31 do not interfere with the upper panel 6 and the connection plate 32, and the thickness of the in-vehicle audio apparatus 1 is decreased as that much.
When the storage tray 22 is further drawn out and moved to the front side, the rollers 34 and 34 are engaged with the center portions of the elevation portions 27c and 27c of the sliding cam portions 27 and 27 in the forward and backward directions (see FIGS. 33 and 34). At this time, the guide pins 29a and 29a of the storage tray 22 are moved while facing the guiding portions 10a and 14a on the front side.
Since the rollers 34 and 34 are engaged with the elevation portions 27c and 27c, the pressing body 30 is maintained at the upper-side moving end.
When the storage tray 22 is further drawn out and moved to the front side, the rollers 34 and 34 are engaged with the rear end portions of the elevation portions 27c and 27c of the sliding cam portions 27 and 27 (see FIGS. 35 and 36). At this time, the guide pins 29a and 29a of the storage tray 22 are moved so as to face the guiding portions 10a and 14a on the front side so as to arrive at the front end portions of the guiding portions 10a and 14a, and the regulating shafts 7a and 11a disposed in the guide rails 4 and are inserted into the regulation grooves 29b and 29b. Accordingly, the movement of the storage tray 22 to the front side is regulated by the regulating shafts 7a and 11.
Subsequently, when a force is applied to the storage stray 22 in the drawing-out direction, the movement of the storage tray 22 to the front side is regulated by the regulating shafts 7a and 11, and the storage tray 22 is turned with the regulating shafts 7a and 11a used as points of supports and is inclined with the front side lowered (see FIGS. 37 and 38). At this time, the guide pins 29a and 29a of the storage tray 22 are inserted into the run-off portions 10d and 14d from the guiding portions 10a and 14a, and the rollers 34 and 34 are engaged with the position regulating portions 27d and 27d from the elevation portions 27c and 27c of the sliding cam portions 27 and 27.
As described above, the movement of the storage tray 22 to the front side is regulated by the regulating shafts 7a and 11 and is turned with the regulating shafts 7a and 11a used as points of supports 7a and 11a so as to be inclined with the front side lowered. Accordingly, the regulating shafts 7a and 11a has two functions including a function of regulating the movement of the storage tray 22 to the front side and a function as the point of supports of the storage tray 22, and therefore, the mechanism can be simplified due to a decrease in the number of components.
When the storage tray 22 is inclined with the front side lowered, the regulation portions 28 and 28 disposed in the rear end portion of the storage tray 22 are inserted into the regulating grooves 18 and 18 formed in the upper panel 6, and the regulation faces 28a and 28a are brought into facial contact with the regulating faces 18a and 18a, whereby the inclination of the storage tray 22 is regulated so as to be maintained at the drawing-out position.
As above, at the drawing-out position, since the regulation faces 28a and 28a are brought into facial contact with the regulating faces 18a and 18a, and the storage tray 22 is maintained in a predetermined inclined state, a large contact area between the regulating grooves 18 and 18 and the regulation portions 28 and 28 is secured, whereby the storage tray 22 at the drawing-out position can secure a stable holding state.
In addition, since the regulating faces 18a and 18a are formed on both left and right end portions of the upper shell 6 of the base body 3, and the regulation faces 28a and 28a are formed in one pair of the side face portions 26 and 26 of the storage tray 22, both parties are brought into contact with each other at two places located on the left and right sides so as to be separated from each other, whereby the holding state of the storage tray 22 at the drawing-out position can be more stably secured.
At the drawing-out position, when the storage tray 22 is tilted in the state of being inclined with the front side lowered, the pressing protruded portions 25a and 25a disposed in the rear face portion 25 are pressed to the lower face of the slide plate 33.
Accordingly, the pressing body 30 is pressed from the lower side by a part of the storage tray 22, and the pressing body 30 can be held in a stable state without any backlash.
In addition, at the drawing-out position, the slide plate 33 is maintained at the front-side moving end by the biasing force of the spring member 35, and at this time, two support pieces 33b and 33b located on the front side are engaged with the regulating protruded portions 15g and 15g of the upper panel 6 from the front side, and the movement of the slide plate 33 to the rear side is regulated by the regulating protruded portions 15g an 15g. 
Accordingly, even when vibration is delivered to the slide plate 33 during the driving of the vehicle, the slide plate 33 is not moved to the rear side in resistance against the biasing force of the spring member 35, and the slide plate 33 is held in the front-side moving end in a stable state, whereby the operation can be appropriately performed.
In addition, at the drawing-out position, the storage stray 22 is drawn out munch from the base body 3, and there is a concern that a user's hand is erroneously in contact with the slide plate 33. However, even in such a case, the slide plate 33 is not moved to the rear side, whereby the operation can be appropriately performed.
As described above, when the storage tray 22 is moved to the drawing-out position, the music reproducing device 100 is inserted into the inside of the storage tray 22 (see FIGS. 3 and 39). The music reproducing device 100 is placed in the bottom face portion 23 of the storage tray 22.
At this time, as described above, since the storage tray 22 is in the state of being inclined with the front side lowered, a user can easily insert the music reproducing device 100 into the storage tray 22, and the convenience of the in-vehicle audio apparatus 1 can be improved.
As described above, when the music reproducing device 100 is inserted into the storage tray 22, the storage tray 22 can be lifted by a user so as to be in a horizontal state from the state of being inclined with the front side lowered (see FIG. 40).
At this time, the storage tray 22 is turned with the regulating shafts 7a and 11a of the guide rails 4 and 5 used as points of supports, and the guide pins 29a and 29a of the storage tray 22 are inserted into the guiding portions 10a and 14a from the run-off portions 10d and 14d. 
In addition, the rollers 34 and 34 are engaged with the elevation portions 27c and 27c from the position regulating portions 27d and 27d of the sliding cam portions 27 and 27.
When the storage tray 22 is rotated to be in the horizontal state, the regulation portions 28 and 28 of the storage tray 22 are separated from the regulating faces 18a and 18a of the regulating grooves 18 and 18 formed in the upper panel 6, whereby contact between the regulation faces 28a and 28a and the regulating faces 18a and 18a is released.
At the same time, the pressing protruded portions 25a and 25a of the storage tray 22 are separated from the bottom face of the slide plate 33, and accordingly, the pressing body 30 is in a state of being movable to the lower side.
Subsequently, the storage tray 22 is pressed to the rear side and is moved to the rear side toward the storing position (see FIG. 41).
When the storage tray 22 is moved to the rear side, the rollers 34 and 34 are rotated above the elevation portions 27c and 27c of the sliding cam portions 27 and 27, and the guide pins 29a and 29a of the storage tray 22 are moved while facing the guiding portions 10a and 14a toward the rear side.
At this time, since the rollers 34 and 34 are engaged with the elevation portions 27c and 27c, the pressing body 30 is held at the upper-side moving end.
Subsequently, when the storage tray 22 is moved to the rear side, the rollers 34 and 34 are engaged with the upper end portions of the ascending portions 27b and 27b from the elevation portions 27c and 27c of the sliding cam portions 27 and 27 (see FIG. 42). At this time, the guide pins 29a and 29a of the storage tray 22 are moved with facing the guiding portions 10a and 14a toward the rear side.
Since the rollers 34 and 34 are engaged with the ascending portions 27b and 27b, the pressing body 30 is moved to the lower side by the biasing forces of the bias springs 38 and 38, and accordingly, the slide plate 33 is brought into contact with the upper face of the music reproducing device 100, and the arm members 31 and 31 are rotated.
As the slide plate 33 is brought into contact with the music reproducing device 100, the movement of the pressing body 30 to the lower side is stopped, and the rotation of the arm members 31 and 31 is stopped.
When the storage tray 22 is moved further to the rear side, the slide plate 33 of the pressing body 30 is brought into contact with the music reproducing device 100 so as to regulate the movement of the pressing body to the lower side, and accordingly, the rollers 34 and 34 are separated from the sliding cam portions 27 and 27 to the front side (see FIG. 43). At this time, the guide pins 29a and 29a of the storage tray 22 are moved while facing the guiding portions 10a and 14a toward the rear side.
The slide plate 33 is biased to the lower side by the basing forces of the bias springs 38 and 38, and accordingly, when the rollers 34 and 34 are separated from the sliding cam portions 27 and 27, the biasing forces of the bias springs 38 and 38 are delivered to the music reproducing device 100 through the slide plate 33, and the music reproducing device 100 is pressed by the slide plate 33 from the upper side.
Although the movement of the slide plate 33 to the lower side is regulated, the slide plate 33 is in the state of being movable to the rear side with respect to the connection plate 32. Accordingly, the slide plate 33 is integrated with the storage tray 22 and the music reproducing device 100 and is moved to the rear side in resistance against the biasing force of the spring member 35 with respect to the connection plate 32.
As described above, according to the in-vehicle audio apparatus 1, the slide plate 33 brought into contact with the music reproducing device 100 is moved to the rear side integrally with the music reproducing device 100 and the storage tray 22, and accordingly, the slide plate 33 is not slid with respect to the music reproducing device 100, whereby scratches or damages of the music reproducing device 100 can be prevented.
In addition, since the slide plate 33 is brought into contact with the upper face of the music reproducing device 100 and is moved to the rear side while the movement thereof in the vertical direction is regulated, regardless of the thickness (the size in the vertical direction) of the music reproducing device inserted into the storage tray 22, the music reproducing device inserted into the storage tray 22 can be pressed by the slide plate 33.
Subsequently, when the storage tray 22 is moved to the rear side, the slide plate 33 is integrated with the storage tray 22 and the music reproducing device 100 and is moved further to the rear side (see FIG. 44). At this time, the guide pins 29a and 29a of the storage tray 22 is moved further with facing the guiding portions 10a and 14a toward the rear side, and the rollers 34 and 34 are continuously in the state of being separated from the sliding cam portions 27 and 27.
When the storage tray 22 is mover further to the rear side, the slide plate 33 is integrated with the storage tray 22 and the music reproducing device 100 and is moved further to the rear side, whereby the storage tray 22 arrives at the storing position (see FIG. 45). The guide pins 29a and 29a of the storage tray 22 pass through the displacement portions 10b and 14b from the guiding portions 10a and 14a and are engaged with the holding portions 10c and 14c. At this time, since the guide pins 29a and 29a are engaged with the displacement portions 10b and 14b inclined with respect to the guiding portions 10a and 14a once, the feeling of the storing of the storage tray 22 up to the storing position is delivered to a user's hand as clicking feeling.
In addition, in the guiding portions 10 and 14, the displacement portions 10b and 14b inclined to the upper side with respect to the guiding portions 10a and 14a and the holding portions 10c and 14c that are continuous from the displacement portions 10b and 14b and are inclined to the lower side with respect to the guide portions 10a and 14a are disposed. Accordingly, in the state in which the storage tray is moved to the storing position, for example, when vibration or the like occurs, it is difficult for the guide pins 29a and 29a to be moved to the side of the guiding portions 10a and 14a, and the holding state of the storage tray 22 at the storing position can be stabilized.
At the storing position, the music reproducing device 100 is pressed to the slide plate 33 biased by the biasing forces of the bias springs 38 and 38 from the upper side, the music reproducing device 100 is held inside the storage tray 22 without any backlash.
When the reproduction of music recorded in the music reproducing device 100 or the like is completed, again, the storage tray 22 is drawn out from the storing position and is moved to the front side up to the drawing-out position from the storing position. The operation of the storage tray 22 at the time of moving the storage tray 22 into which the music reproducing device 100 is inserted from the storing position to the drawing-out position is the same as the above-described operation (see FIGS. 25 to 38) except for a part thereof. Accordingly, of the operations represented below when the storage tray 22 into which the music reproducing device 100 is inserted is moved from the storing position to the drawing-out position, only the operations that are different from the above-described operations will be described, and the description of the same operations as those described above will not be presented.
When the storage tray 22 into which the music reproducing device 100 is inserted is moved from the storing position to the drawing-out position, in the middle of the movement, the rollers 34 and 34 are engaged with the upper end portions of the ascending portions 27b and 27b of the sliding cam portions 27 and 27. Then, as the storage tray 22 is moved further to the front side, the rollers 34 and 34 are rotated from the elevation portions 27c and 27c to the position regulating portions 27d and 27d. 
As the rollers 34 and 34 are engaged with the elevation portions 27c and 27c, as illustrated in FIG. 46, the pressing body 30 is moved to the upper-side moving end, and the slide plate 33 is separated from the upper face of the music reproducing device 100, whereby the holding state of the slide plate 33 for the music reproducing device 100 is released.
Accordingly, when the storage tray 22 is moved up to the drawing-out position, the music reproducing device 100 can be easily taken out from the storage tray 22.
In addition, at the drawing-out position, since the storage tray 22 is in the state of being inclined with the front side lowered, a user can easily take out the music reproducing device 100, and the convenience of the in-vehicle audio apparatus 1 can be improved.
When the slide plate 33 is separated from the upper face of the music reproducing device 100 to the upper side, and the holding state of the slide plate 33 for the music reproducing device 100 is released, the slide plate 33 is moved up to the front-side moving end in accordance with the biasing force of the spring member 35.
As above, when a contact between the slide plate 33 and the music reproducing device 100 is released, the slide plate 33 is moved to the front-side moving end in accordance with the biasing force of the spring member 35, and accordingly, in the state in which the storage tray 22 is moved to the drawing-out position, the slide plate 33 is constantly held at the front-side moving end.
Accordingly, when the storage tray 22 in which the music reproducing device 100 is inserted is moved from the drawing-out position toward the storing position, the slide plate 33 is slid to the rear side in the state in which the music reproducing device 100 inserted into the storage tray 22 is constantly pressed, whereby the music reproducing device 100 can be held in a constantly stable state.
In the above-described in-vehicle audio apparatus 1, a music reproducing device 200 having a thickness, that is, the size in the vertical direction different from that of the music reproducing device 100 can be inserted and held (see FIGS. 47 and 48). The thickness of the music reproducing device 200 is assumed to be smaller than that of the music reproducing device 100.
When the storage tray 22 into which the music reproducing device 200 is inserted is moved from the drawing-out position to the rear side toward the storing position, the rollers 34 and 34 are engaged with the ascending portions 27b and 27b from the elevation portions 27c and 27c of the sliding cam portions 27 and 27, and the pressing body 30 is moved to the lower side in accordance with the biasing forces of the bias springs 38 and 38, whereby the slide plate 33 is brought into contact with the upper face of the music reproducing device 200 (see FIG. 47).
At this time, the amount of movement of the pressing body 30 from the upper-side moving end to the lower side is larger than that in a case where the music reproducing device 100 is pressed.
As the slide plate 33 is brought into contact with the music reproducing device 200, the movement of the pressing body 30 to the lower side is stopped, and the rotation of the arm members 31 and 31 is stopped.
When the storage tray 22 is moved further to the rear side, the slide plate 33 is brought into contact with the music reproducing device 200 so as to regulate the movement to the lower side, and accordingly, the rollers 34 and 34 are separated from the sliding cam portions 27 and 27 to the front side in the pressing body 30.
Since the slide plate 33 is biased to the lower side in accordance with the biasing forces of the bias springs 38 and 38, when the rollers 34 and 34 are separated from the sliding cam portions 27 and 27, the biasing forces of the bias springs 38 and 38 are delivered to the music reproducing device 200 through the slide plate 33, and the music reproducing device 200 is pressed by the slide plate 33 from the upper side.
Although the movement of the slide plate 33 to the lower side is regulated, the slide plate 33 is in the state of being movable to the rear side with respect to the connection plate 32. Accordingly, the slide plate 33 is integrated with the storage tray 22 and the music reproducing device 200 with respect to the connection plate 32 and is moved to the rear side in resistance against the biasing force of the spring member 35.
When the storage tray 22 is moved further to the rear side, the slide plate 33 is integrated with the storage tray 22 and the music reproducing device 200 and is moved further to the rear side, and the storage tray 22 arrives at the storing position (see FIG. 48). At the storing position, since the music reproducing device 200 is pressed from the upper side by the slide plate 33 biased by the biasing forces of the bias springs 38 and 38, the music reproducing device 200 is held inside the storage tray 22 without any backlash.
As described above, in the in-vehicle audio apparatus 1, the amount of movement of the pressing member 30 in the vertical direction changes in accordance with the size of the music reproducing device (100 or 200) inserted into the storage tray 22, and a music reproducing device having any thickness can be pressed by the slide plate 33 so as to be held inside the storage tray 22.
In addition, as described above, in a case where torsion coil springs are used as the bias springs 38 and 38, the biasing forces of the bias springs 38 and 38 change in accordance with the amount of movement of the pressing body 30 from the upper-side moving end to the lower side. In other words, when the amount of movement of the pressing body 30 is small, the biasing forces of the basing springs 38 and 38 are strong, and when the amount of movement of the pressing body 30 is small, the biasing forces of the bias springs 38 and 38 are weakened.
Accordingly, generally, since the weight of a music reproducing device having a large thickness is larger than that of a music reproducing device having a small thickness, by using torsion coil springs as the bias springs 38 and 38, biasing forces according to the weight are applied to the music reproducing device from the bias springs 38 and 38, and the music reproducing device 100 can be maintained in a stable state regardless of the weight thereof.
CONCLUSION
As described above, in the in-vehicle audio apparatus 1, the storage tray 22 that is moved between the drawing-out position and the storing position, the pressing body 30 that is moved in accordance with the moving position of the storage tray 22 in a direction perpendicular to the moving direction of the storage tray 22 and presses the music reproducing devices 100 and 200, and the bias springs 38 and 38 that bias the pressing body 30 are disposed.
Accordingly, a music reproducing device having a different size (thickness) can be held inside the storage tray 22 by pressing it by using the pressing body 30, whereby the range of music reproducing devices that can be inserted into the storage tray 22 is wide so as to improve the versatility.
In addition, the pressing body 30 biased by the bias springs 38 and 38 is moved in the direction perpendicular to the moving direction of the storage tray 22 so as to press the music reproducing devices 100 and 200, and accordingly, the holding state of the music reproducing devices 100 and 200 can be stabilized.
Furthermore, in the in-vehicle audio apparatus 1, a plurality of arm members 31 and 31 are positioned in the moving direction of the storage tray 22 so as to be separated from each other. Accordingly, the movement of the pressing member 30 in the vertical direction is stabilized, and the slide plate 33 can be pressed to the music reproducing devices 100 and 200 with uniform balance, whereby the holding state of the music reproducing devices 100 and 200 can be stabilized.
In addition, since the bias springs 38 and 38 are supported between the upper panel 6 and the arm members 31 and 31, the pressing force of the pressing body 30 for the music reproducing devices 100 and 200 are stabilized, whereby the holding state of the music reproducing devices 100 and 200 can be stabilized.
Furthermore, in the in-vehicle audio apparatus 1, the rollers 34 and 34 supported by the pressing body 30 are engaged with the sliding cam portions 27 and 27 of the storage tray 22 so as to determine the moving position of the pressing member 30, the position of the pressing body 30 with respect to the storage tray 22 can be accurately determined by using a simple mechanism.
In addition, since the sliding cam portions 27 and are formed in the side face portions 26 and 26 of the storage tray 22, the sliding cam portions 27 and 27 do not interfere with the music reproducing devices 100 and 200 inserted into the storage tray 22, and the operation at the time of moving the storage tray 22 can be appropriately performed.
Furthermore, since the rollers 34 and 34 are pressed to the sliding cam portions 27 and 27 in accordance with the biasing forces of the bias springs 38 and 38 that are applied through the connection plate 32, the biasing forces of the bias springs 38 and 38 used for pressing the music reproducing devices 100 and 200 by biasing the pressing body to the lower side are also used as biasing forces for pressing the rollers 34 and 34 to the sliding cam portions 27 and 27. Thus, since springs dedicated for pressing the rollers 34 and 34 to the sliding cam portions 27 and 27 are not necessarily disposed, a decrease in the number of components is achieved, and an appropriate operation of the pressing body 30 can be secured.
In addition, since the rollers 34 and 34 that are rotated in the state of being pressed by the sliding cam portions 27 and 27 are used as cam engaging portions engaged with the sliding cam portions 27 and 27, smooth operations of the storage tray 22 and the pressing body 30 can be secured.
