Embodiments for Carrying Out the Invention

[0012] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Fig. 1(a) is a side view of a railway vehicle 1, and Fig. 1(b) is a cross-sectional view of the railway vehicle 1 taken along the Ib-Ib cross-section line of Fig. 1(a). In Fig. 1, arrow U-D indicates the vertical direction of the railway vehicle 1, arrow F-B indicates the front-rear direction of the railway vehicle 1, and arrow L-R indicates the left-right direction of the railway vehicle 1, and the same shall apply to Fig. 2 and subsequent figures.

[0013] As shown in FIG. 1, the railway vehicle 1 includes a plurality of wheels 2, a bogie (not shown) that pivotally supports the plurality of wheels 2, a car body frame 3 supported by the bogie, a pair of side structures 4 erected from the ends of the car body frame 3 in the vehicle width direction (i.e., the direction of arrow L-R), a pair of end structures (not shown) erected from the ends of the car body frame 3 in the vehicle length direction, and a roof structure 5 that connects the upper ends of the vehicle of the pair of side structures 4 and the pair of end structures. A passenger compartment Ro is formed inside.

[0014] In the passenger compartment Ro, there are provided a floor surface 10 formed on the upper surface of the car body frame 3, a pair of seats 20 disposed on both end sides in the vehicle width direction of the floor surface 10, a pair of side panels 30 disposed adjacent to the seats 20 and erected from the ends of the floor surface 10 in the vehicle width direction, side ceiling panels 40 disposed at the upper ends of the pair of side panels 30, a ceiling panel 50 disposed between the pair of side ceiling panels 40, and a lighting member 70 disposed between the ceiling panel 50 and the pair of side ceiling panels 40.

[0015] The side panel 30 is a panel that forms the wall surfaces on both sides in the vehicle width direction of the passenger compartment Ro. It is connected to the side structure 4, and a luggage rack 31 is disposed at its upper end. The luggage rack 31 is formed to protrude inward (toward the center in the vehicle width direction) of the passenger compartment Ro from the side panel 30. The side ceiling panel 40 is a panel that covers the upper part of the luggage rack 31. One end of it is connected to the side structure 4, and the other end is connected to the roof structure 5.

[0016] The ceiling panel 50 is a panel that forms the ceiling surface between the opposing sides of the pair of side ceiling panels 40, and both ends on both sides in the vehicle width direction thereof are connected to the roof structure 5. This ceiling panel 50 includes a first surface 51 and a second surface 52 arranged side by side in the vehicle width direction, and the first surface 51 and the second surface 52 are each formed in an arcuate concave shape upward perpendicular to the vehicle longitudinal direction (i.e., the direction of arrow F - B), and a bent portion 53, which is the connecting portion between the first surface 51 and the second surface 52, protrudes downward. That is, the first surface 51 and the second surface 52 are each positioned lower toward the center in the vehicle width direction, and are formed in a V shape with the bent portion 53 as the lower end.

[0017] Details will be described later, but a plurality of ceiling panels 50 are arranged side by side in the vehicle longitudinal direction. In the space generated by the V - shaped formation of the ceiling panel 50, there are provided a surveillance camera C (see FIG. 2), which is an information device for photographing images in the passenger compartment Ro, and a sound - collecting microphone M (see FIG. 2), which is an information device for collecting sounds in the passenger compartment Ro. A pair of lighting members 70 are arranged downward from the roof structure 5 at both ends in the vehicle width direction of the ceiling panel 50. The light irradiated from the lighting member 70 can be reflected by the first surface 51 and the second surface 52, and the passenger compartment Ro can be brightly illuminated by the indirect light.

[0018] Next, referring to FIGS. 2 to 5, the ceiling panel 50 will be described. FIG. 2(a) is a bottom view of the ceiling panel 50 in the view of arrow IIa in FIG. 1(b), and FIG. 2(b) is a side view of the ceiling panel 50 and the passenger compartment Ro in the view of arrow IIb in FIG. 2(a). For ease of understanding, only the ceiling panel 50 is shown in FIG. 2(a), and only the ceiling panel 50, the seat 20, and the passenger H sitting on the seat 20 are shown in FIG. 2(b).

[0019] As shown in FIG. 2, a plurality of ceiling panels 50 are arranged side by side along the vehicle longitudinal direction on the ceiling of the railway vehicle 1. In this embodiment, six ceiling panels 50 are arranged side by side for one railway vehicle 1. Inclined surfaces 54 inclined so as to face the seat 20 are respectively formed on both side surfaces in the vehicle longitudinal direction of these ceiling panels 50.

[0020] Specifically, the inclined surface 54 on the front side (i.e., the arrow F direction side) of the ceiling panel 50 is formed to incline forward and upward (i.e., the arrow U direction) from the front end of the bent portion 53, and the inclined surface 54 on the rear side (i.e., the arrow B side) of the ceiling panel 50 is formed to incline rearward and upward from the rear end of the bent portion 53. In the present embodiment, the inclination angle between the bent portion 53 and the inclined surface 54 is set to "120 degrees". Note that the inclination angle of the inclined surface 54 is not limited to 120 degrees and may be 120 degrees or more or 120 degrees or less.

[0021] Among these inclined surfaces 54, a photographing window 55 is formed on the inclined surface 54 where the monitoring camera C is provided, and a sound collecting window 56 is formed on the inclined surface 54 where the sound collecting microphone M is provided. The photographing window 55 is formed at the lower part of the inclined surface 54 where the monitoring camera C is provided, and is an opening toward which a lens (not shown) for photographing a subject in the monitoring camera C is directed. In the present embodiment, the photographing window 55 is formed on the rearward inclined surface 54 of the foremost ceiling panel 50, the rearward inclined surface 54 of the third ceiling panel 50 from the front, the forward inclined surface 54 of the fourth ceiling panel 50 from the front, and the forward inclined surface 54 of the rearmost ceiling panel 50, respectively. Although details will be described later, the monitoring camera C is installed in the space generated by the ceiling panel 50 being formed in a V shape, and the lens of the monitoring camera C is directed toward the photographing window 55. Thereby, the situation in the passenger compartment Ro can be photographed.

[0022] The sound collecting window 56 is formed at the lower part of the inclined surface 54 where the sound collecting microphone M is provided, and is an opening toward which a sound collecting portion (not shown) for collecting sound in the sound collecting microphone M is directed. In the present embodiment, the sound collecting window 56 is formed on the forward inclined surface 54 of the third ceiling panel from the front. Although details will be described later, the sound collecting microphone M is installed in the space generated by the ceiling panel 50 being formed in a V shape, and the sound collecting portion of the sound collecting microphone M is directed toward the sound collecting window 56. Thereby, the sound in the passenger compartment Ro can be collected.

[0023] That is, by installing the surveillance camera C and the sound collection microphone M in the space formed by the ceiling panel 50 being formed in a V shape, it becomes difficult to visually recognize them from inside the passenger compartment Ro. Therefore, it is possible to suppress the sense of intimidation to passengers caused by installing the surveillance camera, and further suppress the deterioration of the appearance of the ceiling panel 50.

[0024] Further, by providing the photographing window 55 and the sound collection window 56 on the inclined surface 54 that is inclined at an obtuse angle with respect to the bent portion 53, the openings of the photographing window 55 and the sound collection window 56 are also directed obliquely downward, specifically, in the longitudinal direction of the vehicle and downward. Thereby, since the photographing range of the surveillance camera C and the sound collection range of the sound collection microphone M can be secured wider on the longitudinal direction side of the vehicle, the number of the surveillance cameras C and the sound collection microphones M installed in the passenger compartment Ro can be reduced.

[0025] Furthermore, the inclined surface 54, the photographing window 55, and the sound collection window 56 are formed on the side surface on the longitudinal direction side of the vehicle in the ceiling panel 50. Therefore, the shapes of the first surface 51 and the second surface 52 are not impaired, and the indirect light reflected by the first surface 51 and the second surface 52 is not blocked. Thereby, such indirect light can be suitably distributed in the passenger compartment Ro, and the video and audio in the passenger compartment Ro can be acquired by the surveillance camera C and the sound collection microphone M.

[0026] Next, with reference to FIGS. 3 to 5, the structure of the ceiling panel 50 will be described. FIG. 3(a) is a top view of the ceiling panel 50 in the arrow IIIa view of FIG. 2(b), FIG. 3(b) is a cross-sectional view taken along the IIIb-IIIb cross-sectional line in FIG. 3(a), and FIG. 3(c) is a side view of the bent portion reinforcing member 59 in the arrow IIIc view of FIG. 3(b).

[0027] As shown in FIG. 3(a), on the upper surface side of the ceiling panel 50, at the end on the longitudinal direction side of the vehicle, a fixture 57 that is a member for fixing the surveillance camera C or the sound collection microphone M to the ceiling panel 50 is provided. The fixture 57 is provided on the ceiling panel 50 via an end reinforcing member 58, a bent portion reinforcing member 59, and an inner reinforcing member 60 to be described later. By fixing the side surface of the surveillance camera C or the sound collection microphone M with the fixture 57, the surveillance camera C or the sound collection microphone M is fixed to the ceiling panel 50.

[0028] The end reinforcing member 58, the bent portion reinforcing member 59, and the inner reinforcing member 60 where the fixture 57 is provided are members (reinforcing members) provided on the upper surface of the ceiling panel 50. The end reinforcing member 58 is a frame-shaped member provided along the entire circumference of the end portion on the upper surface of the ceiling panel 50. The end reinforcing member 58 is attached to the bent portion of the end portion of the ceiling panel 50 (not shown) with an adhesive (not shown). The bent portion of the end portion of the ceiling panel 50 is a portion with high rigidity in the ceiling panel 50. By adhering the end reinforcing member 58 to such a bent portion, it is possible to suppress the ceiling panel 50 from being distorted by the "sink marks" of the adhesive.

[0029] In addition, the end reinforcing member 58 on the vehicle longitudinal direction side is composed of an outer member 58a connected to the end portions of the end reinforcing members 58 on the vehicle width direction side, and a detachable member 58b configured to be detachable from the outer members 58a on both sides.

[0030] The bent portion reinforcing member 59 is a plate-shaped member provided parallel to the central portion of the ceiling panel 50 in the vehicle width direction, that is, the above-described bent portion 53. In the present embodiment, the bent portion reinforcing member 59 is attached to the surface on the roof structure 5 (see FIG. 1) side of the bent portion 53 with an adhesive (not shown).

[0031] As shown in FIG. 3(b), the ceiling panel 50 has a shape in which the first surface 51 and the second surface 52 are bent in a V shape in a cross-sectional view, and the V-shaped bent portion (valley portion) corresponds to the bent portion 53. Since the bent portion 53 is formed by bending the ceiling panel 50, it is a portion with high rigidity. By adhering the bent portion reinforcing member 59 to such a bent portion 53, it is possible to suppress the ceiling panel 50 from being distorted by the "sink marks" of the adhesive.

[0032] Also, as shown in FIG. 3(c), a plurality of side surface openings 59a, which are openings, are formed on the side surface side of the bent portion reinforcing member 59. Thereby, the weight of the bent portion reinforcing member 59 can be reduced, and thus the weights of the bent portion reinforcing member 59 and the ceiling panel 50 can be reduced.

[0033] The inner reinforcing member 60 is a plate-shaped member provided on the inner side in the vehicle longitudinal direction than the end reinforcing member 58 on the vehicle longitudinal direction side of the ceiling panel 50. As shown in Fig. 3(a), the ends on the vehicle width direction side of the inner reinforcing member 60 are respectively connected to the end reinforcing member 58. Further, the ends on the vehicle longitudinal direction side of the bent portion reinforcing member 59 are respectively connected to the inner reinforcing member 60. Thereby, the end reinforcing member 58, the bent portion reinforcing member 59, and the inner reinforcing member 60 are connected to each other.

[0034] The fixture 57 is provided between the end reinforcing member 58 and the inner reinforcing member 60 on the vehicle longitudinal direction side. Specifically, the outer side (the end side of the ceiling panel 50) of the fixture 57 in the vehicle longitudinal direction is connected to the outer member 58a of the end reinforcing member 58, and the inner side (the center side of the ceiling panel 50) of the fixture 57 in the vehicle longitudinal direction is connected to the inner reinforcing member 60.

[0035] Thereby, since the fixture 57 is connected to the end reinforcing member 58, the bent portion reinforcing member 59, and the inner reinforcing member 60, the fixture 57 and the monitoring camera C and the sound collecting microphone M provided on the fixture 57 can be firmly fixed to the ceiling panel 50. At this time, since the monitoring camera C and the sound collecting microphone M are not directly provided on the ceiling panel 50, it is possible to suppress the ceiling panel 50, particularly the first surface 51 and the second surface 52, from being distorted by the weights of the monitoring camera C and the sound collecting microphone M.

[0036] In addition, in Fig. 3, an example in which the fixtures 57 are provided at both ends in the vehicle longitudinal direction of the ceiling panel 50 is shown. However, when the monitoring camera C or the sound collecting microphone M is not provided at either end in the vehicle longitudinal direction of the ceiling panel 50, the fixture 57 and the inner reinforcing member 60 at the corresponding end may be omitted. In that case, the bent portion reinforcing member 59 may be connected to the end reinforcing member 58 at the corresponding end. Also, when neither the monitoring camera C nor the sound collecting microphone M is provided on the ceiling panel 50, the fixtures 57 and the inner reinforcing members 60 at both ends in the vehicle longitudinal direction of the ceiling panel 50 may be omitted, and the bent portion reinforcing members 59 may be respectively connected to the end reinforcing members 58 at both ends in the vehicle longitudinal direction.

[0037] Next, referring to FIG. 4, the inclined surface 54 where the monitoring camera C or the sound collecting microphone M is installed will be described. FIG. 4(a) is a front view of the ceiling panel 50 provided with the monitoring camera C in the vicinity of the upper surface side, and FIG. 4(b) is a front view of the ceiling panel 50 provided with the sound collecting microphone M in the vicinity of the upper surface side. As shown in FIGS. 4(a) and 4(b), the center in the front view of the inclined surface 54 is divided into a substantially pentagonal shape as a detachable protective cover 54b. Further, when the protective cover 54b is removed, the opening formed in the inclined surface 54 is defined as the opening 54a.

[0038] As shown in FIG. 4(a), the above-described photographing window 55 is formed in the protective cover 54b on the side where the monitoring camera C is provided. A photographing window cover 54b1, which is a translucent film (for example, made of polycarbonate) that protects the photographing window 55 and the monitoring camera C, is provided on the photographing window 55. By directing the lens of the monitoring camera C toward the photographing window 55 and the photographing window cover 54b1, the video in the passenger compartment Ro can be photographed. At this time, the photographing window cover 54b1 can protect the lens of the monitoring camera C from dust and the like that are lifted by air conditioning or the movement of passengers, and can also make it difficult for passengers to visually recognize the monitoring camera C.

[0039] As shown in FIG. 4(b), a sound collecting window 56, which is an opening toward which the sound collecting part of the sound collecting microphone M is directed, is formed in the protective cover 54b on the side where the sound collecting part of the sound collecting microphone M is provided. Specifically, the sound collecting window 56 is opened in a slit shape, and a plurality of them are formed with a predetermined interval (for example, 1 mm) in the vertical direction (arrow U-D direction). By directing the sound collecting part of the sound collecting microphone M toward the sound collecting window 56, the sound in the passenger compartment Ro can be collected. In addition, in this embodiment, a plurality of sound collecting windows 56 are formed, but since they are all in a slit shape, it is difficult for passengers to visually recognize the sound collecting microphone M even when they look up at the ceiling panel 50.

[0040] Since the protective cover 54b is detachably provided with respect to the inclined surface 54, even when the protective cover 54b itself, the photographing window 55 and the photographing window cover 54b1 provided on the protective cover 54b, or the sound collecting window 56 are damaged or contaminated, the protective cover 54b can be easily replaced.

[0041] The protective cover 54b is fixed to the inclined surface 54 by a stopper 61 provided on the inclined surface 54, a magnet receiver 54b2 described later, and a hooking member 54b4. The stopper 61 is a slide-type locking member provided straddling the upper part of the inclined surface 54 and the outer member 58a of the end reinforcing member 58. The stopper 61 is provided near the left and right ends at the upper end of the protective cover 54b when the protective cover 54b is provided on the inclined surface 54, with respect to the upper part of the inclined surface 54 and the outer member 58a.

[0042] After fitting the protective cover 54b onto the inclined surface 54, the left and right stoppers 61 are slid and moved to the positions where the inclined surface 54 and the protective cover 54b are respectively locked (i.e., the positions of the stoppers 61 in FIGS. 4(a) and (b)), whereby the upper part of the protective cover 54b is fixed to the inclined surface 54. On the other hand, in a state where the inclined surface 54 and the protective cover 54b are locked by the stopper 61, by sliding the stopper 61 in a direction opposite to the locking direction, the fixation between the upper part of the protective cover 54b and the inclined surface 54 is released. In this way, by simply sliding the stopper 61, the upper part of the protective cover 54b and the inclined surface 54 can be easily fixed and the fixation can be released.

[0043] Next, the case where the protective cover 54b is removed from the inclined surface 54 will be described with reference to FIGS. 4(c) and (d). FIG. 4(c) is a front view when the protective cover 54b is removed from FIG. 4(a), and FIG. 4(d) is a front view when the detachable member 58b is removed from FIG. 4(c). In FIGS. 4(c) and (d), the inclined surface 54 on the side where the monitoring camera C is provided is shown, but since it is substantially the same on the inclined surface 54 on the side where the sound collection microphone M is provided, the illustration and description are omitted.

[0044] As shown in FIG. 4(c), by removing the protective cover 54b, access can be made from below the ceiling panel 50 to the upper surface side of the ceiling panel 50. Thereby, inspection, angle adjustment, etc. of the monitoring camera C or the sound collection microphone M can be performed without removing the ceiling panel 50 from the roof structure 5 (see FIG. 1(b)).

[0045] Also, by removing the protective cover 54b, access can be made to the detachable member 58b from below the ceiling panel 50. Here, since the detachable member 58b is configured to be detachable from the adjacent outer member 58a, as shown in FIG. 4(d), the detachable member 58b can be further removed with the protective cover 54b removed. By removing the detachable member 58b, the upper part of the opening 54a is opened, and the space formed from the opening 54a to the upper surface side of the ceiling panel 50 increases. As a result, it becomes easier to insert the hand of the worker or the like into the opening 54a, so that the workability of inspections, replacements, etc. of the surveillance camera C and the sound collecting microphone M can be improved.

[0046] Magnetic members 54c formed by magnets are respectively provided near the left end and the right end in the opening 54a of the inclined surface 54. As will be described later with reference to FIG. 5, the protective cover 54b is provided with a magnet receiver 54b2 having magnetism, and by fixing the magnetic member 54c and the magnet receiver 54b2 by magnetic force, the protective cover 54b can be fixed to the inclined surface 54.

[0047] Next, referring to FIG. 5, the structure of the protective cover 54b will be described. FIG. 5(a) is a rear view of the protective cover 54b on the side where the surveillance camera C is provided, and FIG. 5(b) is a rear view of the protective cover 54b on the side where the sound collecting microphone M is provided.

[0048] As shown in FIG. 5, on the back surface of the protective cover 54b, that is, when the protective cover 54b is attached to the inclined surface 54, magnet receivers 54b2 formed of a magnetic material (for example, iron) are provided near the left end and the right end of the surface facing upward. Specifically, the magnet receiver 54b2 is provided at a position corresponding to the magnetic member 54c in the protective cover 54b when the protective cover 54b is attached to the inclined surface 54. When the protective cover 54b is disposed in the opening 54a of the inclined surface 54, the magnetic member 54c and the magnet receiver 54b2 are fixed by magnetic force, and thereby the protective cover 54b can be fixed to the inclined surface 54.

[0049] Also, as shown in FIG. 5(a), on the left and right sides of the shooting window 55 and the shooting window cover 54b1 in the protective cover 54b on the side where the monitoring camera C is provided, cover support members 54b3 for supporting the shooting window cover 54b1 are respectively provided. By supporting the shooting window cover 54b1 by the cover support member 54b3, it is possible to prevent the shooting window cover 54b1 from falling off from the protective cover 54b or shifting from the shooting window 55 when the protective cover 54b is attached or detached.

[0050] In addition, a plurality of claw-shaped engaging members 54b4 for engaging with the end of the opening 54a are provided at the end of the protective cover 54b on the side of the shooting window 55 or the sound collecting window 56. By engaging the engaging member 54b4 of the protective cover 54b with the end of the opening 54a, the side of the protective cover 54b on the shooting window 55 side or the sound collecting window 56 side can be fixed to the inclined surface 54.

[0051] That is, as members for fixing the protective cover 54b to the inclined surface 54, a stopper 61, a magnetic member 54c, and an engaging member 54b4 are provided. When attaching the protective cover 54b to the inclined surface 54, the engaging member 54b4 is engaged with the end of the opening 54a of the inclined surface 54, and further the magnetic member 54c is brought close to the magnet receiver 54b2 and fixed by magnetic force, so that the protective cover 54b is "temporarily fixed" to the inclined surface 54. Even if the operator's hand leaves the protective cover 54b, the protective cover 54b will not fall off from the inclined surface 54. After such temporary fixing, the operator who has been released from supporting the protective cover 54b slides the stopper 61, and the protective cover 54b can be completely fixed to the inclined surface 54.

[0052] On the other hand, when removing the protective cover 54b from the inclined surface 54, even if the stopper 61 is slid to the release side, the protective cover 54b can be maintained in a state of being temporarily fixed to the inclined surface 54 by the engaging member 54b4, the magnetic member 54c, and the magnet receiver 54b2. As a result, after the operator releases the stopper 61, the operator can remove the protective cover 54b from the inclined surface 54 while supporting it, so that the protective cover 54b can be easily removed from the inclined surface 54.

[0053] The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments at all, and it can be easily inferred that various improvements and modifications are possible without departing from the spirit of the present invention.

[0054] In the above embodiment, an inclined surface 54 was formed on the side surface of the ceiling panel 50 in the vehicle longitudinal direction, and a monitoring camera C and a sound collecting microphone M were installed on the upper surface side of the inclined surface 54. However, it is not necessarily limited to this. For example, like the ceiling panel 100 in FIG. 6(a), the side surface of the ceiling panel 100 in the vehicle longitudinal direction is formed vertically, and a monitoring camera C and a sound collecting microphone M may be installed on the upper surface side of the vertical side surface in the vehicle longitudinal direction. In that case, by making the position of the lower end of the ceiling panel 101 adjacent to the ceiling panel 100 higher than that of the ceiling panel 100, a wider shooting range of the monitoring camera C and a wider sound collecting range of the sound collecting microphone M installed on the side surface of the ceiling panel 101 in the vehicle longitudinal direction can be ensured.

[0055] Also, like the ceiling panel 150 in FIG. 6(b), the side surface of the ceiling panel 150 in the vehicle longitudinal direction may be formed in a stepped shape, and a monitoring camera C and a sound collecting microphone M may be installed. Or, like the ceiling panel 200 in FIG. 6(c), the side surface of the ceiling panel 200 in the vehicle longitudinal direction may be formed in a curved surface shape, and a monitoring camera C and a sound collecting microphone M may be installed.

[0056] In the above embodiment, the inclined surfaces 54 were formed on both sides of the side surface of the ceiling panel 50 in the vehicle longitudinal direction. However, it is not necessarily limited to this. The inclined surface 54 may be formed only on either one of the side surfaces of the ceiling panel 50 in the vehicle longitudinal direction, or the formation of the inclined surface 54 on the side surface of the ceiling panel 50 in the vehicle longitudinal direction itself may be omitted.

[0057] In the above embodiment, one monitoring camera C or one sound collecting microphone M was provided for one inclined surface 54. However, it is not necessarily limited to this. Two or more monitoring cameras C or sound collecting microphones M may be provided for one inclined surface 54. Also, both a monitoring camera C and a sound collecting microphone M may be provided for one inclined surface 54.

[0058] In the above-described embodiment, the bent portion 53 of the ceiling panel 50 is formed in the longitudinal direction of the vehicle. However, it is not necessarily limited to this, and the bent portion 53 may be formed in the width direction of the vehicle or in any other arbitrary direction.

[0059] In the above-described embodiment, a protective cover 54b of a translucent film that protects the photographing window 55 is provided on the protective cover 54b on the side where the monitoring camera C is provided. However, it is not necessarily limited to this, and the protective cover 54b may be formed of a transparent material, or the protective cover 54b itself may be omitted.

[0060] In the above-described embodiment, six ceiling panels 50 are provided for one railway vehicle 1. However, the number of ceiling panels 50 is not limited to six, and may be six or less or six or more depending on the total length of the railway vehicle 1 or the length of the ceiling panel 50 in the longitudinal direction of the vehicle, etc.

[0061] In the above-described embodiment, the monitoring camera C or the sound collecting microphone M is installed on the upper surface side of the ceiling panel 50. However, it is not necessarily limited to this, and other information devices such as sensors for detecting temperature and noise, and other devices and equipment such as speakers and wireless LAN routers may be installed.

[0062] In the above-described embodiment, the railway vehicle 1 is exemplified as the transportation equipment for installing the ceiling panel 50, the monitoring camera C, and the sound collecting microphone M. However, it is not necessarily limited to this, and the ceiling panel 50, the monitoring camera C, and the sound collecting microphone M may be installed in an automobile such as a sightseeing bus, in a ship such as a ferry, or in other transportation equipment.
