Next, the rotating drum 220 will be described.
5 is a diagram showing a detailed shape of the rotating drum 220, FIG. 5 (a) is a perspective view of the rotating drum 220, and FIG. 5 (b) is an X direction (motor) of FIG. 5 (a). 2 is a view of the rotary drum 220 as viewed from the output shaft 231a side of H.231. FIG. 6 is a view showing a cross section in the Y direction shown in FIG. 5B in a state where the rotating drum 220 is attached to the drum holding member 230.

The rotary drum 220 includes a fastening portion 221 that is fastened to the drum flange 233, a thin cylindrical design sticking portion 222 that is provided with a design, and a connecting portion 223 that connects the fastening portion 221 and the design sticking portion 222. The rotating drum 220 is formed with blades 224 as an example of a stirring unit on the inner peripheral surface of the symbol pasting unit 222.
The fastening portion 221 has a fastening surface 221p perpendicular to the rotation axis of the motor 231. In addition, the fastening portion 221 is formed with two holes 221a through which the screw 235 is passed, and a hole 221b to be fitted with the tip end portion 233b (see FIG. 5) of the drum flange 233. Note that the outer shape of the tip end portion 233b of the drum flange 233 has a shape in which a part of the circle is cut off in a half-moon shape when viewed from the direction of the rotation axis, and the shape of the hole 221b is also a part of the circle in a half-moon shape. The shape is cut into a shape (see FIG. 5B).

The connecting portion 223 extends continuously from the fastening portion 221 to the symbol pasting portion 222. In the rotating drum 220 according to the present embodiment, a plurality (four in the present embodiment) of connecting portions 223 are arranged radially from the fastening portion 221 at regular intervals (90 degrees in the present embodiment) in the circumferential direction. To the symbol pasting part 222.
In addition, since the fastening part 221 and the connection part 223 which concern on this Embodiment are continuing with the same thickness, there is no boundary of the fastening part 221 and the connection part 223, and it is not illustrated. However, for example, the thickness of the fastening portion 221 may be made different from that of the connecting portion 223, for example.

The pattern pasting part 222 is a thin cylindrical shape. On the outer peripheral surface 222a of the symbol pasting portion 222, a symbol on which a film on which the symbol is written is stuck by adhesion or the like is attached. On the other hand, a plurality (four in this embodiment) of blades 224 are provided on the inner peripheral surface 222b side.
The blade 224 protrudes inward from the inner peripheral surface 222b. Further, the blade 224 is formed to extend in a plate shape from one end side to the other end side in the rotation axis direction of the rotary drum 220.

The blades 224 are provided to stir the air inside the rotating drum 220 and to blow air in the direction of the rotating shaft, and in particular, the temperature of the rotating drum 220 and the like rises due to heat generated due to the driving of the motor 231. To suppress.
Therefore, from the viewpoint of stirring and blowing more air, it is preferable that the area of the blade 224 protruding inward from the inner peripheral surface 222b of the rotating drum 220 (area for stirring air) is as large as possible. Therefore, it is preferable that the height H (see FIG. 6) of the blade 224 protruding inward from the inner peripheral surface 222b of the rotating drum 220 is as high as possible. Further, the length L (see FIG. 5) of the blade 224 is preferably as long as possible.

In the blade 224 according to the present embodiment, in addition to the above-described viewpoint of stirring and blowing more air, the viewpoint of forming the rotating drum 220 more easily is also considered as follows. The shape of the blade 224 is determined.
In order to make the length L of the blade 224 as long as possible, and so that more air can be stirred and sent in the direction of the rotation axis, the rotating drum 220 is curved from one end side to the other end side in the rotation axis direction. . For example, as shown in FIG. 5, the blades 224 are spirally curved from the end in the rotation axis direction of the rotary drum 220 to the fastening surface 221p.

  The region where the blades 224 are provided extends from the end portion on the motor 231 side in the rotation axis direction of the rotating drum 220 to the fastening surface 221p of the fastening portion 221. This is due to the following reason. That is, when the rotary drum 220 is molded, a molding die that slides in the direction of the rotation axis of the rotary drum 220 is used, and injection molding is performed using a material such as resin. Therefore, as described above, when the blade 224 is curved from one end to the other end in the rotation axis direction of the rotary drum 220, the structure of the mold becomes complicated, The thickness of the blades 224 may become extremely thick due to the split of the two molds that are relatively slid. In order to prevent these, it is preferable to provide the blades 224 only on either side of the rotating drum 220 in the rotation axis direction with the fastening portion 221 as a boundary. Therefore, in the present embodiment, in order to stir more around the motor 231 and to send air around the motor 231 in the direction of the rotation axis, the fastening portion 221 extends from the end of the rotation drum 220 on the motor 231 side in the rotation axis direction. The blades 224 are provided up to the fastening surface 221p.

  Moreover, in the blade | wing 224 which concerns on this Embodiment, in order to make the height H which protrudes inside from the internal peripheral surface 222b of the rotating drum 220 as much as possible, it does not interfere with the thing arrange | positioned inside the rotating drum 220. The height H is determined so that the blade 224 and the object facing the blade 224 come close to each other in the range. That is, in the drum unit 210 according to the present embodiment, since the motor 231 and the motor holding member 232 are disposed inside the rotary drum 220 so as to face the inner peripheral surface 222b, the clearance in the radial direction between them is arranged. Make CL as small as possible.

  In FIG. 6, the clearance between the blade 224 and an object existing inside the rotary drum 220 is simply shown. As shown in FIG. 6, in the drum unit 210 according to the present embodiment, the motor base 232a of the motor holding member 232 has a more inner surface 222b than the motor main body 231c in which the coil of the motor 231 is built. close. And it is thought that the heat generated from the motor 231 is mainly generated from the coil. For this reason, the height of the blade 224 is set in two stages, and the height of the portion 224a that mainly faces the motor base 232a is different from the height of the portion 224b that mainly faces the motor main body 231c. And the height H of the blade | wing 224 in the site | part 224b which opposes the motor main body 231c with which a coil is incorporated is determined so that the blade | wing 224 may adjoin the motor 231 in the range which does not interfere with the external shape of the motor 231. As described above, the blades 224 are spirally curved in the direction of the rotation axis of the rotary drum 220, but are simply shown linearly in FIG.

  In the drum unit 210 having the rotary drum 220 having the shape described above, the rotary drum 220 is rotated by the rotational drive of the motor 231. At the same time, the blades 224 formed on the inner peripheral surface 222b of the rotary drum 220 rotate. Thereby, even if heat is generated by driving the motor 231, the blades 224 stir the air around the motor 231. Further, since the blades 224 are spirally curved, the air around the motor 231 is sent in the direction of the rotation axis, and moves to a region inside the rotary drum 220 where the motor 231 does not fit. Further, the air around the motor 231 passes between the rotating drum 220 and the drum holding member 230 and is sent to the outside of the rotating drum 220.

In the symbol display unit 200 in the present embodiment, a drum holding member 230 is configured by attaching three motors 231 to one motor holding member 232 having a substrate. Then, after three rotating drums 220 are mounted on the drum holding member 230 to form one drum unit 210, the three drum units 210 are stored in the storage case 250 adjacent to each other at a predetermined interval. That is, a region where the motor 231 of the drum unit 210 adjacent to each other is partitioned by the motor holding member 232. Therefore, it may be difficult to discharge the heat of the motor 231 generated due to the driving of the motor 231 from the inside of the rotating drum 220 to the outside in the direction of the rotating shaft of the motor 231.
In the image display unit 114 according to the present embodiment, since the liquid crystal display unit 400 is disposed on the front side of the symbol display unit 200, there is a gap between the symbol display unit 200 and the liquid crystal display unit 400. May be smaller.

  However, in the image display unit 114 according to the present embodiment, as described above, the blade 224 is provided on the inner peripheral surface 222b of the rotary drum 220, and the air around the motor 231 is stirred by the blade 224. It is possible to suppress the symbol display unit 200 including the rotating drum 220 from becoming high temperature with a simple configuration. And since it can suppress that the motor 231 becomes high temperature, the torque fall of the motor 231 can be suppressed. Therefore, it is not necessary to use the high-output motor 231 and the cost of parts can be reduced.

  Moreover, since the blade | wing 224 is curving helically, for example, it blows also to the rotating shaft direction of the rotating drum 220. FIG. As a result, air with heat generated due to the driving of the motor 231 is sent to the outside of the rotating drum 220 through the gap between the rotating drum 220 and the motor holding member 232, for example, the side surface and the back surface of the storage case 250. The slits 250b formed on the image display unit 114 are discharged to the outside. Therefore, it is possible to further prevent the symbol display unit 200 including the rotating drum 220 from becoming high temperature. And since it can suppress that the motor 231 becomes high temperature and a torque fall can be suppressed, it is not necessary to use the high output motor 231, and reduction of components cost can be aimed at.
