The selection switch unit 37 is connected to the power supply unit 50 so that the power of the vehicle power supply unit 50 can be applied to the driving motor M side. The selector switch 37 is composed of predetermined selector switches SW1, SW2, and SW3, and the selector switches SW1, SW2, and SW3 are configured to limit the respective limit switches LSW1, LSW2, and LSW3. It is supposed to work. In addition, the selection switch unit 37 is generally provided with a switch controller 38, the switch controller 38 is to control each switch (SW1, SW2, SW3).

An example of the present invention configured as described above will be described in detail with reference to the drawings.

The character display apparatus according to the present invention is assembled in the state as shown in FIG. 1, and is firmly fixed to the inside of the rear side of various automobiles 70 through the fixing pieces 17a and 17b as shown in FIG. This allows the rear vehicles to see the see-through windows 11a and 11b. In addition, the first to third selection switches SW1 to SW3 having the switch controller 38 are installed in a place where the driver can easily operate the switch. Normally, as shown in FIG. 5A, only the letters “light driving” are displayed to the wheelers of the rear vehicle through the first viewing window 11a. In addition, when braking during driving, the brake auxiliary light 20 is generally turned on like the brake light 51, and the lighting state of the brake auxiliary light 20 is visible to the rear vehicle through the second viewing window 11b. do.

On the other hand, if the lane is easily changed due to the driver's concession of the following rear vehicle when the lane is to be changed while driving, the driver appreciates one of the first to third selection switches SW1 to SW3. When the first selection switch SW1 of the switch controller 38 capable of displaying a letter “” is pressed, the fluorescent lamp 34 is turned on and the switch SW1 is caused by the contact of the first selection switch SW1. Since the first limit switch LSW1 corresponding to is also pressed by the contact by the switching member 32 to form a contact state with the driving motor M, the power from the power supply unit 50 is transferred through the common unit C. It is quickly applied to the motor M side.

In the case where only the first selection switch SW1 is selected, the second and third selection switches SW2 and SW3 are turned off, so that the second and third limit switches SW2 and SW3 corresponding thereto are turned off. Power is not applied to the camera. In addition, when the second or third selection switches SW2 and SW3 are selected, the rest is in a non-energized state. When the driving motor M is rotated, the cylindrical on / off switching member 32 and the character display member 31a integral with the driving motor M are illuminated in the fluorescent lamp 34 and are driven in the driving direction of the motor M. Rotate in the direction of the arrow (Figure 2). When the catchword, the next letter of the letter display member 31a, reaches the first see-through window 11a, the electric contact with the motor M side due to the contact with the cylindrical switching member 32 until then. When the first limit switch LSW1 is in a state of contact with the long hole 33 of the switching member 32 formed at a position corresponding thereto, the contact piece of the first limit switch LSW1 is The state of being immersed in the long hole 33 by the elastic force. As the contact piece of the first limit switch LSW1 is immersed in the long hole 33, the electrical contact with the motor M side is short-circuited, and thus the driving motor M stops rotation, The character display member 31a, which is integrated with this, is also stopped and the letter “Thank You” is visible on the rear vehicle through the first viewing window 11a [figure 5b]. Furthermore, the light of the fluorescent lamp 34 is dark or cloudy. At this time, since the pseudo-indication character 31b is more clearly seen, a large visual effect is given to the driver of the rear vehicle. In this state, when a predetermined time (approximately 8 seconds to 10 seconds) has elapsed, the tire T having a predetermined chip (T) is only a power source that allows the motor M to be rotated to its original initial position. The motor M is driven to its original state by being applied. Since the operation of the driving motor M by the timer T is a general technology, a detailed description thereof will be omitted. When the motor M is returned to its original state, only the light weight operation is visible again through the first viewing window 11a as shown in FIG. 5A. In addition, when the driving motor M is stopped, the fluorescent lamp 34 is turned off. It is in a state. If you want to yield to a rear vehicle due to other lane changes, or if you are sorry to a rear vehicle due to a lane change, you can select the selection switch (SW2) or (SW3) to select the corresponding character, respectively. . At this time, the necessary characters are displayed in the viewing window through the same process as the above embodiment.

The same parts as in the above embodiment are denoted by the same reference numerals to avoid redundant description. In the second embodiment, the drive motor M is directly installed in the automobile brake 60, and two limit switches LSW1 and LSW2 are electrically connected to the drive motor M. Unlike the above-described embodiment, the first and second limit switches LSW1 and LSW2 control the driving motor M to rotate 360 °.

When the brake 60 is pressed in such a configuration, the auxiliary brake light 20 and the fluorescent light 34 are turned on, and the first and second limit switches LSW1 and LSW2 are displayed on the letter display member shown in FIG. Since it is pressed by the switching member 32 integrally with 31a and is in contact with the motor M side, the drive motor M and the characters integrated therewith are shown in Figs. 5a and 5b. As shown, while being illuminated by the fluorescent lamp 34, it is visible to the rear vehicle through the viewing window 11a of the second degree display. In this case, the text display unit 31 may include an advertisement text and a figure to produce an advertisement effect. When the letter display unit 31 is rotated 360 ° like the motor M, the contact piece having the elastic force of any one of the limit switches LSW1 or LSW2 has a long hole in the switching member 32 of FIG. It is immersed in (33), and the electrical contact is short-circuited with the drive motor M side. Therefore, the fluorescent lamp 34 is turned off and the driving motor M is stopped in the original state. Even if the brake 60 is pressed once and then released, the driving motor M is rotated 360 ° at a predetermined speed by the power supplied once.

In addition, when the brake 60 is continuously pressed, the motor M is automatically rotated 360 ° by the timer T in the same manner as in the above embodiment when a predetermined time (approximately 18 to 20 seconds later) elapses. It rotates a bit to show the character needed by the rear vehicle. While the brake 60 is pressed, such an operation is repeatedly executed. Since driving of the driving motor M by the timer T is a general technology, a detailed description thereof will be omitted.

As described above, according to the present invention, it is possible to display the unsatisfactory intention of the driver by the character display means for the unsatisfactory matters accompanying the driving of the vehicle. There is an advantage that high dynamic visual effect can be obtained.

In addition, there is an effect that it is possible to supply a large amount of goods at a safe price by a simpler structure than the character expression means of the conventional light emitting diode, and also it is easy to replace parts.
