[Embodiment of the invention]

 Hereinafter, in order to make the features and purposes of the alarm device of the present invention easier to understand, a detailed description will be given from FIG. 1 to FIG. In the circuit diagram of the present invention shown in FIG. 1, the audible alarm circuit 10 for issuing an audible alarm in an emergency situation, the oscillating circuit 20 for issuing an oscillating signal for driving, and the frequency of the oscillating signal of the oscillating circuit 20 are appropriately set. It has a frequency dividing circuit 30 for lowering the clock frequency of the light emitting circuit, a blinking switching circuit 40 for switching the blinking speed of the light emitting circuit, and a light emitting circuit 50 for driving the light emitting diode.

In the alarm device of the present invention, the light emitting circuit blinks at different speeds in a normal state to achieve an aesthetic effect, but in an emergency situation, a sound alarm for crime prevention is issued. The voice alarm circuit 10 is composed of an alarm switch 11, an inverter 12, a JK flip / flop device 13, an AND logic gate 14, an alarm oscillator circuit 110, an alarm device 15 and an alarm driving transistor 16. The alarm oscillating circuit 110 can be replaced by a well-known oscillating circuit, but here it is composed of a resistor R, a capacitor C and three 111 inverters, and emits a vibration signal for driving the alarm device 15. The voice alarm circuit 10 is a circuit for issuing a voice alarm in an emergency situation.

The oscillator circuit 20 is composed of two NAND logic gates 21, resistors R2 and R3, and a capacitor C2. If the values of R2, R3 and C2 are adjusted, a higher frequency output can be obtained. The frequency dividing circuit 30 is composed of several JK flip-flop units 31, 32 and 33, and has a function of appropriately reducing the frequency of the vibration signal generated by the oscillation circuit 20. The number of the JK flip-flops depends on the frequency after frequency division.

The blinking switching circuit 40 includes a manual switch 41, an inverter 42, JK flip-flops 43, 44, 45, logic gates O, P, Q, R, S1, S, M, N, Z1, Z. The flashing speed of the light emitting circuit 50 can be manually converted by a capacitor and a dielectric. The light emitting circuit 50 is composed of six shift counting registers A, B, C, D, E, F, buffers F1 to F6, and six light emitting diodes LED1 to LED6. The substance is a JK flip-flop device. The buffers F1 to F6 acquire signals by the open collector method at the Q terminal of the JK flip-flop device and drive the light emitting diode with a larger current. These concatenated JK flip-flops act as concatenated shift counting registers, where the light-emitting circuit 50 can emit a flashing signal with a aesthetic and warning effect in a predetermined manner there.

Hereinafter, the operation and usage of the alarm device will be described. For convenience, it is assumed that the alarm device is already mounted on the bicycle. If it is not an emergency state, when the manual switch 41 of the blinking switching circuit 40 is pressed once, the output Q of the JK flip-flop unit 43 becomes high potential (H), and the AND logic gate O and the frequency dividing circuit 30 are connected. The output Q of the JK flip-flop unit 32 and the output Q of the JK flip-flop unit 43 utilize high potential (H), and the obtained vibration signal is sent to the logic gate S via the logic gates Q and S1, The output of the logic gate S sets the signal level of the output terminal Q in the JK flip-flops A, B, C, D, E and F to a high potential (H). This signal is collected by the buffers F1 to F6, and a drive current is sent to the light emitting diodes LED1 to LED6. After a while, the product circuits R5 and C4 set the output terminals Q of the JK flip-flop units A, B, C, D, E and F to a low potential (L) via the logic gates Z1 and Z, and the light emitting diode LE D1. ~ Turn off the light of LED6. Therefore, the light emitting diodes LED1 to LED6 of the light emitting circuit 50 emit a continuous blinking signal in accordance with the vibration signal sent by the JK flip-flop unit 32 of the frequency dividing circuit 30.

When the blinking speed is desired to be changed, when the manual switch 41 of the blinking switching circuit 40 is pressed once more, the output Q of the JK flip-flop 44 becomes high potential (H), and this signal is further AND logic. The gate P performs logical calculation with the output Q of the JK flip / flop unit 33 of the frequency dividing circuit 30. The obtained vibration signal is sent to the logic gate S via the logic gates Q and S1, and the output of the logic gate S is output from the output terminals Q of the JK flip-flop units A, B, C, D, E and F. Set the signal level to high level (H). The signals are collected by the buffers F1 to F6, and drive currents are sent to the light emitting diodes LED1 to LED6. After a while, the integrating circuits R5 and C4 set the output terminals Q of the JK flip-flops A, B, C, D, E, and F to low potential (L) through the logic gates Z1 and Z, and the light emitting diodes LED1 to LED1. Stop the light from LED6. Therefore, the light emitting diodes LED1 to LED6 of the light emitting circuit 50 emit a continuous flashing signal in accordance with the vibration signal sent by the JK flip-flop device 33 of the frequency dividing circuit 30. In other words, by pressing the manual switch 41 of the blink switching circuit 40, signals of different blink rates can be obtained. This is because the JK flip-flop units 32 and 33 of the frequency dividing circuit 30 have different frequency dividing effects.

When an emergency situation occurs, the alarm switch 11 of the voice alarm circuit 10 is pushed, the obtained signal passes through the inverter 12 and the JK flip-flop device 13, and the AND logic gate 14 causes the alarm oscillation circuit 110 to operate. The generated vibration signals are combined and input to the alarm device driving transistor 16, the alarm device 15 is activated, and a voice alarm is issued. In consideration of cost and volume, all the electronic components of the alarm device of the present invention can be integrated except the alarm switch 11 and the manual switch 41.

Figure 3 shows a commercialized alarm device attached to different parts of a bicycle. The alarm device 201 is attached to the bicycle 202. The built-in light emitting diodes LED1 to LED6 blink when the bicycle 202 is moving at night or during the daytime, and the sound alarm buzzer can emit a crime prevention sound in an emergency situation. The alarm device of the present invention can also be mounted on traffic equipment such as an automobile.
