Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a fish bark display device.

2. Description of the Related Art A display device suitable for detecting the vibration of a fishing line has a portion which engages with the fishing line when the display device is used and a vibration sensor which is connected to the engaging portion. One previously proposed structure has consisted of an antenna whose engaging portion was linked to a mechanical switch. More recently, the engagement portion comprises a notch member mounted at one end of the bimorph.

[0003]

The problem that occurs in the antenna structure is that the angler does not interfere with the detection device (clear o
f) It is difficult to throw or wind your own rod and thread. A problem with the notch structure is the frictional contact between the engaging member and the thread, especially when it is moving in the longitudinal direction. In some cases, the thread may even hit the engaging member. It is an object of the present invention to provide means for relieving the above problems.

[0004]

Means for Solving the Problems and Effects of the Invention In order to achieve the above object, the present invention is a fish barn display device having a rotating portion which is engaged with a fishing line when the display device is used,
It has a vibration sensor coupled to the rotating part for detecting the vibration of the fishing line, whereby the vibration of the rotating part caused by catching a fish can be detected by the vibration sensor, and at the same time, the part of the display device which is engaged with the fishing line, that is, the rotation. The part is slightly adapted to the longitudinal movement of the fishing line.

The vibration sensor is composed of a piezoelectric element, and preferably the vibration sensor is composed of a bimorph. Preferably, the alarm signal generator is coupled to the vibration sensor via a threshold level adjusting means, thereby changing the sensitivity of the display device to the vibration of the fishing line.

The display device may further include a rotation sensor coupled to the rotating portion for rotation detection, whereby the same portion of the display device is engaged by the fishing line to cause vibration and longitudinal movement of the fishing line. Allows for both sensing. Accordingly, the movement of the fishing line can be detected in a wide range, and a relatively large movement in the longitudinal direction can be detected from mere vibration. Vibration sensitivity can be reduced to virtually zero for wind conditions (land fishing) and over-board fishing (boat fishing).
This allows the same display device to be used in both stationary and unstable environments.

An alarm signal generator may be connected to the rotation sensor via the sensitivity adjustment, which makes it possible to change the sensitivity of the display device to the rotation of the rotating part. The rotation sensor may be adapted to generate a signal for each rotation of the rotating part at a predetermined angle.

The rotation sensor may include a counter configured to generate a display device signal according to each count of signals received from the rotation sensor, where the count is an integer greater than or equal to one. The counter is configured so that each count number can be changed, and further has a manual adjustment member connected to the counter, which enables the count to be changed, thereby changing the sensitivity of the display device to the rotation of the rotating portion. is there.

As shown in FIG. 3, an inwardly threaded horizontally extending portion 88 is formed within the housing portion. The number of holes (not shown) formed in the other housing is 2
When the two housing parts come together, they are in registration with the portion 88, and the ribs 50 engage the grooves of the other housing part with screws (not shown) to secure the two housing parts together.

Most of the circuit diagram of FIG. 9 corresponds to that of FIG. 4 of EP-A-0 570 117. As described above, the reed switch 76 includes a part of the magnetic sensor circuit 148 connected to the buzzer 34 having the diaphragm 32 via the digital counter 150, the sensitivity mode selector 42, and the gate serially connected in order from the switch 76 to the buzzer 34. And the oscillator 152. Oscillator 1

Change. The sensitivity controller 42 is connected to the counter 150. As a result, the controller 42 adjusts the selector 42 to change the number of pulses received by the counter from the reed switch 76 before the controller 42 issues a square wave pulse to the gate oscillator 152.

As also shown in FIG. 9, a battery 82 is connected to energize various parts of the circuit via the on / off / test switch 36. LED via drive circuit 155
Battery test circuit 154 with output connected to 20
To another output from the switch. Switch 3
When 6 is pushed to the test position (the test position away from where it was elastically forced to its off position by means not shown), battery test circuit 154 measures the voltage from battery 82 and battery 82 provides it. When the electric power meets the conditions, the LED 20 is made to flash for about 1 second.

Besides, the LED 20 does not emit any light during the test. When the fixed delay timer 158 connected between the output of the counter 150 and the LED 20 holds the ON state and receives the pulse of the counter 150, the LED 20 is turned on for a predetermined time, for example, 10 seconds. Preferably, the circuit is configured with a microprocessor or other integrated semiconductor microchip programmed to operate according to the operating procedure described herein.

The bimorph 102 is connected to a vibration sensor circuit 160 having a sensitivity controller 162. The controller sets the required signal threshold for the bimorph 102 before the vibration sensor circuit 160 provides the output signal. The controller is connected to the gate oscillator 152 via the sensitivity controller 42.

Details of the circuit described only in the block diagram of FIG. 9 are shown in FIG. The circuit configuration shown in FIG. 10 consists of the parts given in the circuit diagram of FIG. 9 and is within the dashed line with the corresponding reference numerals. The magnetic sensor circuit 148 includes a reed switch 76 serially connected to a debounce gate 201 and a buffer gate 202, which are serially connected in series with each other.
Note that it consists of. The output from the buffer gate 202 is connected to the input of the counter 150.

The vibration sensor circuit is composed of the bimorph 102, and the potentiometer forming the vibration sensor circuit 162 is connected across the bimorph 102. The center tap is the comparator 2
07 inverting input. The non-inverting input to the comparator 207 is maintained at the corresponding voltage via a resistor bridge. The output from the comparator 207 is connected to a NAND gate which has another input connected to the output from the magnetic sensor circuit. This is a line with a count of 1,
That is, it is a line that gives an output pulse each time the counter 150 receives an output pulse. Therefore, this is the most sensitive setting for the sensitivity mode switch 42. Multi-position switch type sensitivity mode selector 42, capacitors 209 and 219, and diode 21
The output from the counter 150 is connected to the Schmitt NAND gate 214 via the time circuit composed of 1, 212 and the resistor 213. The output from this gate is transmitted to the timer 158, which alternately has an output connected through switch 36 to both the light emitting diode 20 and the audio signal generating circuit. These are tones (or pitches)
It comprises a gate oscillator 152 with a controller 40.

The tone controller is a simple potentiometer connected between two gates 215 and 216 in series with the gate oscillator 152. The output from the gate 214 is also connected to the timer 158 and the two gates 224,
A capacitor 221 for driving the LED 20 via an LED drive circuit 155 composed of 225 and a transistor 226.
The resistor 222 forms the timer. The audio amplifier 153 is composed of a bridge type drive circuit connected to the output of the gate oscillator 152. The audio amplifier has its output connected to a buzzer 34 consisting of a piezoelectric speaker.

When the indicator is used, the fishing line of the fishing rod is passed through the rotating portion 26. In this way, any movement of the fishing line in the longitudinal direction causes the reed switch 76 to open or close at a frequency corresponding to the moving speed of the fishing line. The pulses thus generated are rebounced and buffered by the gates 201 and 202 of the magnetic sensor circuit 148. These pulses flow to the input of the counter 150 and the output group connected to the selector 42. The first of these four outputs gives a pulse each time the counter receives a pulse and the second gives a pulse after both two pulses have been received by the counter.
The third is output after one received pulse, and the fourth is output after eight. This effectively provides sensitivity control, causing the switch position to rise as the longitudinal movement of the line required to produce the output gradually increases. The last switch position selects the vibration sensor mode and the output of the vibration sensor circuit is connected via the NAND gate 208 to trigger the timer 158 and the gate oscillator 152. Therefore, the LED 20 and the buzzer 34 each directly emit an audiovisual signal, and the vibration of the fishing line is transmitted from the rotating portion 26 to the bimorph 102.

This is accomplished by virtue of the piezo-generated voltage developed by the bimorph 102, which is applied across the potentiometer 162 and modifies its central tapping potential. Thus, the central tapping position adjustment consists of the vibration sensitivity controller 162, since the controller determines the voltage level transmitted to the comparator 207 for the provided voltage developed in the bimorph 102. The non-inverting input of comparator 207 is maintained at a constant voltage V _REF , which determines the minimum voltage sensed. Therefore,
The output of the comparator changes state instantaneously when the fishing line oscillates to such an extent that a voltage exceeding V _REF is _generated in the sensor. The pulse from the output of the comparator is combined with the pulse of the magnetic sensor circuit 148 via the NAND gate 208 which sends it to the final position of the multi-position switch sensitivity selector 204. Output of bounce gate 201 and selector 2
04 output, between the gate 208 and the final output from the selector 204, and between the corresponding output from the counter 203 and its final output respectively, the illustrated resistors 231, 232, 233 are Zero ohms. These are used to give various arbitrary characteristics.

The pulse from the selector 42 is supplied to the capacitors 209 and 210, the diodes 211 and 212 and the resistor 21.
3 to the timing circuit. The output signal from this timer circuit is sent to the Schmitt NAND gate 214. Using the output from the gate, the gate 21
5. Trigger the audio gate oscillator 152 composed of 5, 216 and 217. By changing the frequency of the gate oscillator with the potentiometer 218, the buzzer 34
It is possible to change the tone (or pitch) of the audio signal generated in. The output from the gate oscillator 152 is supplied to the bridge type drive circuit to drive the buzzer 34. The output volume can be controlled through the potentiometer 220. The output from the gate 214 also passes through the LED drive circuit 155 composed of the gates 224 and 225 and the resistor 226, and the timer 1 formed by the capacitor 221 for driving the light emitting diode 20 and the resistor 222.
Initialize 58.

In order to prevent acoustic feedback in the vibration sensor mode of the display device, the output of the gate 214 is also the diode 22.
7 is connected to the non-inverting input of the comparator 207. This effectively mute the input during the pulse. Capacitor 228 lengthens the pulse length so that resonances in the display housing die away when the signal to speaker 34 ceases.

The battery test circuit 154, which comprises the integrated circuit 229 and its associated components, is enabled by switching the switch 36 to its third or test position. When the battery voltage meets the condition, the light emitting diode 20 emits light.
