Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mounted on an emergency vehicle for alerting, installed on a construction site, or installed in a game shop where a game machine such as a pachinko machine or a pachislot machine is installed. Related to rotating lights.

[0002]

2. Description of the Related Art A rotary lamp generally includes a lamp and a reflector that can rotate around the lamp, and is used as follows by turning on the lamp and rotating the reflector. Have been. For example, a rotating light is attached to an emergency vehicle such as an ambulance or a police car, or installed at a construction site, and is used for alerting people around it. Also, in a game store where a gaming machine such as a pachinko machine or a pachislot machine is placed, a rotating light is installed for each gaming machine and is used to display the state of the gaming machine. The rotating light is used, for example, to display whether or not the gaming machine is in a big hit state.

[0003]

However, the conventional rotating lamp has a state in which the lamp is turned on and the reflecting plate is rotating.
Since the lamp can be used only in one of the two states, that is, the state where the lamp is turned off and the reflector is at rest, it cannot be used to display three or more states. For example, if a rotating light is installed for a gaming machine that has three states: a normal state, a jackpot state, and a probability varying state, the conventional rotating light has only two use states, so the gaming machine has three states. Cannot be displayed in any of the states.

Accordingly, an object of the present invention is to provide a rotating lamp including a lamp and a reflector that can rotate around the lamp, and which can display three or more states. I do.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a lamp, a reflector which can rotate around the lamp, a motor for rotating the reflector, A driving circuit that drives a motor to rotate the reflection plate, wherein the driving circuit rotates the reflection plate at one speed selected from two or more different speeds. Provide a rotating light configured.

In the rotating lamp according to the present invention, since the reflector rotates at one speed selected from two or more different speeds, it is possible to change the rotation speed of the reflector by changing the selected speed. it can. As a result, the rotating lamp of the present invention has, for example, a first state in which the lamp is turned off and the reflector is stationary, a second state in which the lamp is turned on and the reflector is rotating at a low speed, and a lamp. Lights up and the reflector is rotating at a high speed (higher than the rotation speed of the reflector in the second state) in at least three states of the third state. Therefore, by the rotating lamp of the present invention,
Three or more status displays can be performed.

[0007] The reflector may be directly connected to the rotating shaft of the motor. Thereby, the structure of the rotating light can be extremely simplified. The reflector may be connected to the rotating shaft of the motor via a mechanical deceleration transmission mechanism. Examples of the motor include a stepping motor, a DC motor, and a shading motor. When a stepping motor is used as the drive source, the motor rotation speed can be changed by changing the frequency of the pulse signal input to excite the motor coil, and thus the rotation speed of the reflector can be changed.

The rotation speed of the reflector may be selectively set from among two or more different speeds using a switch or the like. In this case, the motor drive circuit may rotate the reflector at a speed set by a switch or the like.
Further, a signal for instructing the rotation speed of the reflector may be input to the motor drive circuit. In this case, the drive circuit may rotate the reflection plate at a speed selected based on the rotation speed instruction signal.

The rotating light of the present invention can be installed in a game machine such as a pachinko machine or a pachislot machine and used as follows. For example, a gaming machine having two or more predetermined states is installed for a gaming machine that outputs a state signal indicating which state the gaming machine is in, and different ones corresponding to each state of the gaming machine are provided. From among two or more speeds, the reflector may be rotated at a selected speed corresponding to the state of the gaming machine based on the state signal. More specifically, for example, there are three states of a normal state, a jackpot state, a probability fluctuation state, when a rotating light is installed for a gaming machine that outputs a state signal indicating which state, for example, When the gaming machine is in the normal state, the reflector rotation speed is set to zero (stationary state), when the gaming machine is in the probability fluctuation state, the reflector rotation speed is set to low, and when the gaming machine is in the jackpot state, the reflector is rotated. When the rotation speed is made to correspond to the high speed (speed higher than the low speed), when the game machine is detected to be in the normal state from the state signal input from the game machine, the lamp is turned off and the reflection plate is set to the stationary state, When the probability signal is detected from the status signal, the lamp is turned on to rotate the reflector at a low speed, and when the gaming machine is detected from the status signal as the jackpot, the lamp is turned on to rotate the reflector at a high speed. It may be rotated. By doing so, it is possible to know the state of the gaming machine by observing the state of the rotating lamp (whether or not the lamp is on and the rotational speed of the reflector (the rotational speed of light reflected by the reflector)). it can.

FIG. 1A shows a schematic front view of an example of the rotating lamp according to the present invention. FIG. 1B shows a schematic side view of the rotating lamp. This rotating light is used for displaying the state of the pachinko machine in this example.

The rotating lamp includes a lamp 1, a reflector 2 rotating around the lamp 1, a stepping motor 3 as a motor for rotating the reflector 2,
A circuit board 6 on which a drive circuit for the motor 3 and a lighting circuit for the lamp 1 are formed. The lamp 1, the reflector 2, the motor 3, etc.
And a light-transmitting cover 82 fitted to the cover 81 and covering the upper portion thereof.

The lamp 1 is screwed into a lamp holder 11 and supported by the holder. The holder 11 is supported by the main shaft 5 at a fixed position attached to the base plate 4. A large gear G2 is fitted around the shaft 5, and the gear G2 can rotate around the shaft 5 by its bearing 51. The bearing 51 may be omitted depending on the material of the shaft and the gear G2. For example, when the gear G2 is made of synthetic resin having good slidability, it can be omitted.

The reflecting plate 2 is capable of reflecting the light emitted from the lamp 1 and has a concave curved surface portion 21 partially covering the periphery of the lamp 1 and a pedestal portion 22 continuous with the concave curved surface portion 21. ing. The pedestal portion 22 is attached to a gear G2 that is rotatably fitted to the main shaft 5. A through hole 221 is provided at the center of the pedestal portion 22, and the lamp holder 11 is arranged so as to fit into the hole 221. Thus, the gear G2 is connected to the shaft 5
, The concave curved surface portion 21 of the reflection plate 2 can be rotated about the lamp 1.

The motor 3 is a four-phase stepping motor having a magnet rotor MR and coils L1, L2, L3 and L4 as shown in FIG. The motor 3 is mounted on a base plate 4. Rotary shaft 3 of motor 3

As shown in FIG. 4, in this embodiment, the rotating lamp is provided for the pachinko machine, and is used for displaying the state of the pachinko machine. This pachinko machine exhibits one of three states of a normal state, a jackpot state, and a probability fluctuation state, and the rotating light indicates which state the pachinko machine is in. The rotating lamp operates as follows in this example according to the state of the pachinko machine as described later. When the pachinko machine is in the normal state, the rotating light turns off the lamp 1 and brings the reflecting plate 2 into a stationary state. When the pachinko machine is in the probability fluctuation state, the rotating light
Is turned on to rotate the reflector 2 at a low speed. When the pachinko machine is in the jackpot state, the rotating light turns on the lamp 1 to rotate the reflector 2 at a high speed (faster than in the probability fluctuation state).

The pachinko machine outputs the following two status signals indicating the state of the pachinko machine. The status signal is input to the circuit board 6 of the rotating lamp. The jackpot state signal (in the circuit of FIG. 3, “Lo” in the circuit of FIG.
A level indicates a jackpot state) and a probability fluctuation state signal indicating whether or not the state is a probability fluctuation state (in the circuit of FIG. 3, a level “Lo” indicates that the state is a probability fluctuation state). Is input. The pachinko machine is in the normal state when neither the big hit state nor the probability fluctuation state is present.

The circuit board 6 is supplied with 24 V AC as a power supply voltage in addition to the two state signals from the pachinko machine. The power supply voltage AC24V is generally prepared and used in a game shop where a game machine such as a pachinko machine or a pachislot machine is installed. From AC 24 V, DC 34 V is used as the motor drive voltage Vcc by the motor DC power supply 62.
Is generated. In addition, from DC34V generated by the motor DC power supply 62, D
C5V is generated.

The lamp 1 is lit by a lamp lighting circuit 66. The lamp lighting circuit 66 controls turning on / off of the lamp based on the big hit state signal and the probability fluctuation state signal. The lamp lighting circuit 66 lights the lamp 1 when the pachinko machine is in a jackpot state or a probability fluctuation state,
At other times, that is, when the pachinko machine is in the normal state, the lamp 1 is turned off.

The motor 3 is driven by a motor drive control circuit 65 that sequentially switches the transistors Tr1 to Tr4 in synchronization with a pulse signal of a predetermined frequency output from the pulse generation circuit 64. In the circuit shown in FIG. 3, the motor drive control circuit 65 includes a stepping motor control driver U1 (TOSHIBA TA841).
5P), and the driver U1 includes the transistors Tr1 to Tr4 in FIG.

The motor drive control circuit 65 switches the transistors Tr1 to Tr4 to excite the motor coils L1 to L4 in synchronization with a pulse signal as shown in FIG. 5, thereby turning the magnet rotor MR. In this example, the motor coil is excited by the 1-2 phase excitation method. The rotation of the magnet rotor MR of the motor 3 rotates the reflector 2. The reflection plate 2 includes a pulse generation circuit 64
It rotates at the number of rotations (rotational speed) proportional to the frequency of the pulse signal output from. As the frequency of the pulse signal increases, the rotation speed of the reflector 2 also increases.

The motor control circuit 65 determines the motor coils L1 to L based on the jackpot state signal and the probability fluctuation state signal.
Excitation of 4 is performed. The motor control circuit 65 excites the motor coil when the pachinko machine is in the jackpot state or the probability variation state, and does not excite the motor coil in other cases, that is, when the pachinko machine is in the normal state.

The pulse generating circuit 64 outputs a pulse signal of a predetermined frequency based on the jackpot state signal and the probability fluctuation state signal. In this example, when the pachinko machine is in the big hit state, a pulse signal of a higher frequency is output than in the probability fluctuation state. Thereby, the rotation speed of the reflection plate 2 when the pachinko machine is in the big hit state is faster than when the pachinko machine is in the probability fluctuation state.

In the circuit shown in FIG. 3, a Schmitt inverter U2, two resistors R1 and R2 connected in parallel via a contact RLs, and a capacitor C1
A pulse generation circuit (oscillation circuit) 64 is configured to open and close the contact RLs and change the time constant to change the frequency of the output pulse signal as follows. The contact RLs is a contact (make contact) of the timer relay, and the contact RLs closes after a set time has elapsed since the relay coil RLc was excited. The excitation state of the relay coil RLc is controlled by the jackpot state signal. When the pachinko machine is in the probability fluctuation state (when not in the jackpot state),
The relay coil RLc is not excited, the relay contact RLs is open, and a pulse signal having a frequency corresponding to the time constant of the resistor R2 and the capacitor C1 is output. Further, when the pachinko machine is in the state of the big hit, the relay coil RLc is excited, and the relay contact RLs is closed when a predetermined time elapses after the relay coil RLc is excited.
The time constant is smaller than when is open. Thus, when the pachinko machine is in the big hit state, the frequency of the output pulse signal is higher than in the probability fluctuation state. When the pachinko machine changes from the normal state to the jackpot,
Since the reflection plate 2 must be started to rotate from a stationary state, if the frequency of the pulse signal output from the pulse generation circuit 64 is high, the stepping motor 3 easily loses synchronism. Therefore, in the pulse generation circuit 64 of FIG.
By using a timer relay, the frequency of the pulse signal is initially lowered, and after a predetermined time has elapsed, switched to a desired high frequency to prevent the stepping motor 3 from stepping out. In the pulse generation circuit 64 shown in FIG. 3, the frequency of the pulse signal is changed by changing the time constant by changing the constant of the resistance. However, the time constant may be changed by changing the constant of the capacitance of the capacitor. Alternatively, the time constant may be changed by changing both the resistance and the capacitance.

As described above, when the pachinko machine is in the normal state, the lamp 1 of the rotating light is turned off and the reflection plate 2 is in the stationary state. When the pachinko machine is in the probability fluctuation state, the lamp 1 of the rotating light is turned on and the reflector 2 rotates slowly. When the pachinko machine is in the big hit state, the lamp 1 of the rotating light is turned on, and the reflector 2 rotates at a high speed (faster than in the probability fluctuation state). Therefore, by looking at the state of the rotating light, the pachinko machine is in the normal state, the probability fluctuation state,
It is possible to know which of the jackpot states. That is, three states can be displayed by the rotating lamp of the present invention.

In the above description, the rotating light is installed on the gaming machine and the rotating light is used for displaying the state of the gaming machine. However, the rotating light can be used as follows. A revolving light may be installed at the entrance of the parking lot so that the lamp is turned on and the reflector is turned slowly during normal times, and the lamp is turned on and the reflector is turned quickly when passing through the vehicle. In this way, the vehicle is rotating even during normal times, so it is possible to notify surrounding people, vehicle drivers, etc. that there is an entrance to the parking lot, and to alert the driver. Become even more alert to the people around you.

Although a stepping motor is used as a drive source for rotating the reflection plate in this embodiment, a DC motor or the like may be used.
