Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a new and innovative multi-panel display unit mutually rotating display device, and more particularly to an empty vehicle display device installed on the roof of a taxi.

2. Description of the Related Art It is well known that a display displaying characters such as "vacant" has been installed on the dash board inside a taxi and is visible from the outside through the windshield. The ``vacant'' display on the display is all one-sided, and in rare cases there are taxi cars that have an additional display at the rear so that the ``vacant'' display can be seen from behind through the rear window.

Conventional taxi vacancy indicators can be roughly divided into two types; one is a system in which an vacancy display board is fixed to the operating arm of the taxi meter, and when the display board is tilted down, the taxi meter starts counting. There are two types: one is a manual type, and the other is electrically connected to a taxi meter and configured so that a designated display appears by switching the line voltage generated by pressing a button on the meter. In the latter type of display, ``empty car'' and ``surcharge'' are displayed by switching the flashing position of a lamp, and the other method is to electromechanically rotate a tape with multiple display surfaces to display the specified display. A monitor display with a flashing lamp is provided on the back of the cover display.

Problem: The conventional empty taxi display is hidden in the shadow of the car in front during traffic jams and cannot be seen, so passengers who see the taxi after it arrives immediately raise their hands and the taxi suddenly stops near the sidewalk. There were many. In addition, among conventional empty vehicle indicators, the display of optical display types fades due to sunlight, and in particular, when the display surface faces direct sunlight, the empty vehicle display becomes invisible9.
There were many cases in which passengers raised their hands when they saw the train coming just before the train, and both cases were unfavorable from the standpoint of accident prevention.

There is no double-sided empty vehicle display. However, a taxi car equipped with one empty car display device at the front and one empty car display device at the rear can notify customers and following cars of the status of the empty car and the actual car, but the empty car in the front When a ``board displaying forwarding'' is posted in front of a display, there are many cases where the same display is not posted on both the front and back, and there have been cases where customers have complained because the front and rear displays are different.

In addition, taxis with a "departure board" posted in front of the empty vehicle display
On cars, the word "Forwarding" was not displayed with light, making it difficult to see at night, leading to complaints from customers.

From the above-mentioned accident prevention and complaint countermeasures, it is desirable to install a taxi vacancy indicator on each taxi with a double-sided display, but a fixed company name signboard (ANDON) is installed on the roof of the taxi. This created a problem in installing empty vehicle indicators.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention is configured such that signboards (ANDON) are arranged side by side on the mounting base of the empty car display device, and the power lines, signal lines, etc. of the display device and the signboard are connected. In addition to using the same wiring, the display surface of the display device is constructed as a double-sided display type, and the transparent cover that covers the exterior of the display device is extended to become the interior cover of the signboard. The display surface of the display device and the signboard surface are configured so that the display surface of the display device and the signboard surface are internally illuminated by an illumination member that passes through the center of both display surfaces of the taxi in the axial direction and is exposed inside the interior cover of the signboard, so that the display device and the signboard can be used as a taxi. It is now possible to coexist side by side on the rooftop.

In addition, the inner cylinder rotor and the outer cylinder rotor, whose display surfaces have different rotation radii, are mounted on a support shaft provided in the display mechanism so that they can rotate relative to each other, and the display position engages with both rotors. A detection mechanism and a drive mechanism are provided so that the display surface of the outer cylinder rotor rotates in forward and reverse directions on the outside of the display surface of the inner cylinder rotor, and an image display is provided on the mechanism part cover having display windows on both sides. The device is arranged so that the display surfaces of the outer cylinder rotor and the inner cylinder rotor appear in the window, and when the opening (display window) of the outer cylinder rotor appears in the display windows on both sides, the inner cylinder rotor is displayed. The display surface is configured so that it can be seen from the outside, and the display surfaces of the inner cylinder and outer cylinder are marked with "vacant car", "letter or plain display indicating rental run", "pick-up car", "forwarding", "charter or reservation", etc. A control circuit section electrically connected to the detection mechanism and drive mechanism is used to control the switch and taxi.
It is connected to a meter device and when the switch is operated, a specified display appears in the display windows on both sides and stops, and a lock lever provided on the drive mechanism prevents the free movement of both display rotating bodies. We have completed a suitable display device that can be installed on a taxi.

In addition, an extraction hole with a water-resistant cap is provided on the side of the transparent cover and mechanism cover, and the lighting member can be removed from the machine through the extraction hole or inserted into the machine by sliding it in the axial direction. A red security light is attached to the vehicle, and the control circuit that is electrically connected to the lighting component and the security light is connected to the vehicle width light (small lamp) switch and the security light switch, and when the small lamp switch is turned on, the lighting component lights up. At this time, when the security light switch is turned on/off, the lighting component is automatically turned off and the red security light flashes, adding a security function to this display. This display device can be put to practical use by allowing the component to be easily taken out of the machine without disassembling it.

In addition, in areas with heavy snowfall, a transparent cover containing heat rays is attached to the transparent cover surface in front of the display window to melt the snow, or an alternative heat source for melting is provided in the device to separate the snow.

As the relative rotation progresses, the toothed parts 27 and 3 of both gears 27 and 38
When the rotation of 8D or 38E continues until the meshing state is released, the outer peripheral surface of the disc portion 27C of the outer cylinder drive gear 27 wedges into the toothless portion 38B of the driven gear 38, and the outer cylinder The groove cam 27A of the drive gear 27 is the lock lever.
The lever 49 is configured to push up the guide pin 49B so that the wedge-fitting part 49A of the lever 49 wedges into the toothless part 38B of the driven gear 38, turning the rotation detection switch 46 off or on (Fig. 9). ).

Then, during one rotation of the outer cylinder and the drive gear 27, the outer cylinder display body 9
It is configured so that it rotates in steps of 60 degrees and then stops.

The groove cam 39 of the outer cylinder display body 9 has an outer cylinder detection switch 4.
0, the location of both grooves 39B that turns off or on both the outer cylinder detection switches 40 and 41, and the outer cylinder detection switch 4.
There is a location in the inner groove 39C where only one switch is turned off or on.

When the opening 9E of the outer tube display body 9 faces the seven display windows on both sides, the inner groove 39C of the groove cam 39 is configured to be in a position where it acts only on the outer tube detection switch 41. In this state, the display surface of the inner barrel display 8 can be viewed from the outside through the transparent cover 6 through the display window 7A and the opening 9E of the outer barrel display 9 on both sides (as shown in FIG. 2). .

When the outer cylinder display body 9 rotates at an angle of 60 degrees and stops while the outer cylinder driving gear 27 rotates once with the rotation of the motor 25, the grooves 39B and 390 of the groove cams 390 and 40 detect the outer cylinder detection switches 40 and 4.
1. The structure is such that it is located at a position where it acts on both. In this state, the inner cylinder display body 8 is inside the display windows 7A on both sides.
(See Figure 9)
The display surface of the front half of the outer cylinder display body 9 can be visually recognized from the outside through the transparent cover 6 in the display windows 7A on both sides. For example, on the display surface there is a message written in navy blue or red on a white background.
"Forwarding" is printed on the screen (this display surface will be referred to as the "forwarding display surface" in the following explanation).

Further, when the outer cylinder display body 9 further rotates by 60 degrees and stops while the outer cylinder drive gear 27 rotates once together with the motor 25, the outer groove 39A of the groove cam 39 is placed at a position where it acts only on the outer cylinder detection switch 40. It is structured so that it will come. In this state, the display surface (see FIG. 1O) of the rear half (angle of 60 degrees) of the outer tube display body 9 can be visually recognized from the outside through the transparent cover 6 and inside the display windows 7 on both sides. On the display surface, for example, an indication of "private" or "reservation" is printed in dark blue letters on a white background or white letters on a dark blue background (this display surface will be referred to as a "private display surface" in the following explanation).

Further, when the outer barrel drive gear 27 tries to rotate together with the motor 25 in the same direction as the above-mentioned rotation, the outer barrel display 9 cannot rotate because the gear 27 faces the toothless portion 38F of the driven gear 38. There is.

However, from this state, the outer cylinder drive gear 2 together with the motor 25
7 rotates in the opposite direction, the outer cylinder display body 9 rotates in the opposite direction by an angle of 60 degrees for each reverse rotation of the gear 27, and the outer cylinder drive gear 27
When the display cylinder 9 rotates in the opposite direction, the opening 9E of the outer cylinder display body 9 comes to a position facing the display windows 7A on both sides and stops. If the motor 25 tries to rotate further in the reverse direction, the outer cylinder drive gear 27 faces the toothless portion 38F of the driven gear 38, so that the outer cylinder display body 9 cannot rotate.

FIGS. 11 and 12 are explanatory diagrams of the operation of the inner tube display body 8, etc., and are the outer tube display body? 1 shows a cross section thereof, and the driving members and the like are omitted.

The wiring 121 connected to the output side of the security light flashing circuit 135 is connected to the security light 13.

The interfaces 122 and 123 in the display controller lOO and the lighting control circuit 132 are connected by a signal line 140, and the configuration is such that the positional relationship of input signals is checked and a signal is output according to the state of the input signal.

When the small lamp switch 203 is on, the lighting control circuit 132 outputs a lighting signal to the signal line 141 and inputs it to the inverter circuit 133, so the circuit 133 outputs a lighting voltage (for example, a high frequency voltage of ?0KH2) to control the lighting components. 16 is configured so that it lights up.

When the emergency light switch 202 is turned on when the lighting member 16 is lit, the lighting control circuit 132 stops outputting the lighting signal to the signal line 141, and the circuit 132 outputs the lighting signal to the signal line 142, thereby switching on the security light blinking circuit. 135, the blinking circuit 135 outputs a blinking signal (for example, an on/off signal at 1 second intervals) so that the security light 13 does not change its blinking state. When the emergency light switch 202 is turned off, the original state is restored.

When the fare push button 213 of the taxi meter 205 is turned on, the signal is input to the interface 122 via the sign controller 208 and the signal line 107c, so the circuit 122 receives the signal generated from the fare push button (hereinafter referred to as (referred to as a running signal) is isolated, the input levels are matched, and the signals are output to signal lines 143, 144 and 140. Similarly, when the empty car push button 211 is turned on, an empty car signal is input to the interface 122 via the signal line 107A, and when the pick-up push button 212 is turned on, a pick-up signal is input to the interface 122 via the signal line 107B. It has become.

When the transfer switch 102 is turned on, a transfer signal is input to the interface 123 via the signal line 105A, and when the charter switch 103 is turned on, a charter signal is input to the interface 123 via the signal line 105B. When the signal is input to the interface 123, the circuit 123
detects the contents of the reception signal in the interface 122, and the interface 123 outputs a signal (forced switching signal) to switch the display to the rental mode, and inputs the signal to the interface 122 and the lighting control circuit 132 via the signal line 140. The configuration is such that a transmission signal or the like is inputted to the signal conversion circuit 125 via a signal line 145 and inputted to the motor control circuit 129 via a signal line 146.

The signal conversion circuits 124 and 125 have the function of converting input signals into binary numbers, and the output signal line 147 of the circuit 124 is connected to the position detection comparison circuit 126, and the signal conversion circuit 125
The output signal line 148 is connected to the position detection comparison circuit 127. The output signal line 150 of the comparison circuit 127 is connected to the motor drive circuit 131. The output signal line 149 of the position detection comparison circuit 126 is input to the motor drive circuit 130. The motor drive circuit 130 and the motor control circuit 128 are connected by a signal line 151, and the motor control circuit 129 and the motor drive circuit 131 are connected by a signal line 152.

When the forward switch 102 (or charter switch 103) is on, the forced switching signal output from the interface 123 is input to the interface 122, so the circuit 122 changes the display regardless of the signal input via the sign controller 208. A signal for switching is output to the position detection comparison circuit 126 via the signal conversion circuit 124, and is also input to the motor control circuit 1 via the signal line 144.
The configuration is such that a signal is input to 28.

The position detection comparison circuit 126 compares the input signal with the contents detected by the inner cylinder detection switches 42 and 43, and outputs a signal to the motor drive circuit 130. At the same time, the motor control circuit 128
compares the input signal with the detection contents of the inner cylinder detection switches 42 and 43, outputs a signal for controlling whether to rotate the motor 26 forward or backward, and inputs the signal to the motor drive circuit 130 via the signal line 151. The circuit 130 outputs a voltage with a polarity determined for forward or reverse rotation to the wirings Ill and 112, so that the motor 26 rotates. When the input signal and the contents of the inner cylinder detection switches 42 and 43 match in the position detection comparison circuit 126, the output of the motor drive command signal of the comparison circuit 126 is stopped. However, the motor 26 continues to rotate while the rotation detection switch 47 is on, and stops when the switch 47 is turned off.

At the same time, the rotation signal output by the interface 123 is input to the motor control circuit 129 through the signal line 146, and is also input to the position detection circuit 127 through the signal line 145, the signal conversion circuit 125, and the signal line 148. The detection circuit 127 receives the input signal and the outer cylinder detection switch 4.
The detected contents of 0 and 41 are compared and a motor drive signal is output to the motor drive circuit 131. At the same time, the motor control circuit 128 compares the input signal with the detection contents of the outer cylinder detection switches 4o and 41, and outputs a signal to control whether the motor 25 is rotated forward or backward. Since the voltage is input to the drive circuit 131, the circuit 131 outputs a voltage whose polarity is determined as normal rotation or reverse rotation to the wirings 114 and 115, so that the motor 25 rotates. Then, when the input signal and the contents of the outer cylinder detection switches 40 and 41 match in the position detection comparison circuit 127, the comparison circuit 127 stops outputting the signal for driving the motor 25. However, the motor 25 continues to rotate while the rotation detection switch is on, and stops when the switch is turned off.

As described above, when the forwarding switch 102 is turned on, the motors 25 and 26 rotate, and the inner cylinder display body 8 rotates step by step within the display window 7A shown in FIG. is displayed, the motor 26 stops, and the display plates 9C and 9 of the outer cylinder display body 9 are displayed in front of the display surface 8G.
D rotates and covers the display plates 9C and 9D so that the "forwarding display surfaces" appear in the display window 7A and the motor 25 stops rotating. At this time, the lighting member 16

When the "forwarding display" or "private display" of the outer tube display 9 is displayed in the display window 7A, turn on the push switches 211 and 212 of the taxi meter 205 for empty cars, pick-up cars, etc. The configuration is such that the display in the display window 7A cannot be changed even if it is turned off.

When both the forwarding switch 1゜2 and the charter switch 103 in the switch box IO-1 are off, the opening (display window) 9E of the outer cylinder display body 9 opens into the display window 7A. Therefore, at this time, the display surface 8F of the inner cylinder display body 8 and the like can be visually recognized from the outside within the display window 7A.

When both the forwarding switch 102 and the charter switch 103 are off, operate the pushbutton switches 211, 212, 213, etc. of the taxi meter 205 to
It is configured such that a desired display surface can be caused to appear and stop appearing in the display window 7A by rotating forward and backward in steps.

When the actual vehicle display surface 8G appears in the display window 7A and stops, a rental running signal is input to the interface 122 via the sign controller 208, and the signal output from the circuit 122 is sent to the lighting control circuit via the signal line 140. 132, the control circuit 132 is configured to stop outputting the lighting signal to the signal line 141, so the lighting member 16 cannot be lit. However, when the switch 134 is on (or off), the lighting section 16 is configured to be lit even when a rental running signal is input.

Since the present invention is constructed as described above, in use, the display device l is attached to the objective mounting member 3 (for example, the suction cup 3 shown in the figure).

The wedge part 50 of the lock lever 50 is opposed to the toothless part 37B of the driven gear 37, and the wedge part 50 of the lock lever 50 is moved by the action of the groove cam 28A.
A wedges into the toothless portion 37B of the driven gear 37. This progressive rotation causes the inner groove 36 of the groove cam 36 of the inner cylinder display body 8 to
C is opposed to the inner cylinder detection switches 42 and 43, and the switch 43 is turned off and the switch 42 is turned on, and the signal is input to the position detection circuit 126 and the motor control circuit 128 and compared with the input signal. If they match, the motor is activated. Since the output of the drive signal is stopped, when the inner cylinder detection switch 47 is turned off, the motor 26 stops rotating, and the actual vehicle display surface 8G of the inner cylinder display 8 appears in the display window 7A and stops.

When the empty car push button 211 of the taxi meter device 205 is turned on, the motor 26 rotates in reverse, and the empty car display surface 8F appears in the display window 7A, and then the motor 26 stops.
