Next, the operation of FIG. 3 will be explained with reference to the signal waveforms of FIGS. 4 and 5.

Now, if you touch the pair of electrodes (1) with your hand at time t1 in FIG. 4 to short-circuit them, that is, when you touch them for the first time, the resistance value between them becomes small and the touch sensor circuit (2)
The base potential of the transistor (24) becomes low 1, and the transistor (24) turns on. Then, a signal is obtained on the collector side of the transistor (24), which is waveform-shaped by the inverters (31) and (32) of the switch circuit (3), and a pulse as shown in the fourth prisoner is generated on the output side. A signal Sea is obtained. This pulse signal Sla is supplied to the clock terminals CK of the DFF circuits (33) and (34), and as a result, the output signal S2 of the output terminal Q of the DFF circuit (33) is at a high level (H ) to a low level (L), and the inverted output signal S3 thereof changes from a low level to a high level as shown in FIG. 4C.

When the inverted output signal S of the DFF circuit (33) becomes high level, the diode (41) of the OR circuit (4) is turned off and the transistor (52) is turned on. As a result, the transistor (6) is turned on, and the lamp (7) is turned on to be in a full-light state. That is, the first touch of the electrode (1) causes the lamp (7) to become fully illuminated.

Next, when the pair of electrodes (1) is touched for the second time at time t2 in FIG.
is turned on, and a pulse signal Slb as shown in FIG. 4A is obtained at the output side of the inverter (32). This pulse signal Slb is supplied to the clock terminals CK of the DFF circuits (33) and (34), and as a result, although the output signal S2 and the inverted output signal Ss of the DFF circuit (33) remain unchanged, the DFF circuit (34) Output terminal S4 of output terminal Q of
changes from high level to low level as shown in the fourth diagram, and the inverted output signal Ss of the inverted output signal time is the fourth
As shown in Figure E, the low level changes to the high level.

When the output signal S of the DFF circuit (34) becomes low level, the diode (81) of the dimming oscillator (8) is turned off, the oscillator (8) starts operating, and the output side, that is, the inverter (83) An oscillation signal having a predetermined pulse width as shown in FIG. 5 is generated on the output side of the oscillator.

When the oscillation signal is high level, the diode (42
) is off and transistors (52) and (6) are on, lighting up the lamp (7), but when the oscillation signal is low level, the diode (42) is on and transistor (52) is turned on.
and (6) are turned off, and the lamp (7) is turned off. In other words, the lamp (7) is turned on in the high level section T1 in Fig. 5, and the lamp (7) is turned off in the low level section T2.
By repeating this state, it is possible to maintain a so-called dimming state in which the brightness is darker than the full light state. That is, the second touch of the pair of electrodes (1) causes the lamp (7) to enter the dimming state. By arbitrarily setting this interval T and the second interval, it is possible to adjust the light to an appropriate brightness.

Here, the oscillation period T, for example, of about 100 m sec is perceived as flickering to the human eye, so in this embodiment, it is set to about 39 m sec or more, as an example.

Next, at time t in FIG. 4, a third electrode is applied to the pair of electrodes (1).
When you touch it for the second time, a transistor (24) appears as above.
is turned on, and a pulse signal Slc as shown in FIG. 4A is obtained at the output side of the inverter (32). This pulse signal SIC is supplied to the clock terminals CK of the DFF circuits (33) and (34), and as a result, the output signal S2 of the DFF circuit (33) goes from the low level to the high level as shown in FIG. The output signal S3 changes from high level to low level as shown in Figure 4C, and the output signal S of the OFF circuit (34) changes from low level to high level as shown in Figure 4, and its inverted output signal Ss changes from high level to low level as shown in Figure 4E.

When the inverted output signal S3 of the DFF circuit (33) becomes low level, the diode (41) is turned on and the transistors (52) and (6) are turned off. Further, when the output signal S4 of the DFF circuit (34) becomes high level, the diode (81) is turned on and the oscillator (8) stops operating. As a result, the lamp (7) goes out. In other words, the third touch on the pair of electrodes (1) causes the lamp (7
) will be turned off.

On the other hand, in the full light state when the pair of electrodes (1) is touched for the first time or the dimming state when the pair of electrodes (1) is touched for the second time, the lamp (7) is automatically turned off after a predetermined period of time has elapsed. That is, the first touch on the electrode (1) causes the DFF circuit (
When the output signal S2 of the frequency divider (9) becomes low level, the output signal S2 of the frequency divider (9
) is cleared and starts counting the oscillation signal from the oscillator (10), and when a predetermined time elapses, for example, 3 to 4 minutes, the output of the frequency division output terminal DV changes from the low level to the high level, and this Inverter (9
1) is inverted and supplied to the preset terminal PR of the DFF circuit (33), and the output signal S2 is set to high level.
Invert the inverted output signal S to low level and perform DFF times!
8 (33), the lamp (7) is automatically turned off at that point.

Note that at the time when the pair of electrodes (1) is touched for the second time and the pulse signal Slb is generated, the output signal S of the DFF circuit (33) is supplied to the clear terminal CLR of the frequency divider (9).
Since the level of 2 remains at low level,
In the dimming state, the lamp (7) is turned off not from the second touch, but after a predetermined time, for example 3 to 4 minutes, has elapsed in total from the first touch.

In this way, in this embodiment, the brightness can be easily switched between the full light state and the dimming state simply by touching the electrode.
Therefore, if it is too bright in a bedroom or the like, the brightness can be dimmed to an appropriate level by adjusting the light, and the life of the battery can be extended accordingly.

FIG. 6 shows the configuration of a second embodiment of the present invention. In the figure, parts corresponding to those in FIG. 1 are denoted by the same reference numerals, and detailed explanation thereof will be omitted.

In this embodiment, the oscillator (10) used in FIG. 1 is also used as a dimming oscillator (8), and the other configurations are the same as in FIG. 1.

Now, when the pair of electrodes (1) is touched for the first time by hand, this is detected by the touch sensor circuit (2) and its detection output is supplied to the switch circuit (3). The switch circuit (3) forms an on signal according to the detection output, and the transistor (
6) and turn it on.

Turning on the transistor (6) turns on the lamp (7), resulting in the brightest full-light state.

At this time, the dimming oscillator [8] also becomes operational,
Although an oscillation signal with a predetermined pulse width is generated, priority is given to the ON signal directly supplied from the switch circuit (3) to the OR circuit (4), and the all-optical state is maintained.

Next, when the pair of electrodes (1) is touched for the second time, the ON signal supplied directly from the switch circuit (3) to the OR circuit (4) disappears, and the oscillation from the dimming oscillator (8) disappears. A signal is supplied to the base of the transistor (6) via the OR circuit (4) and the drive circuit (5). The transistor (6) is repeatedly turned on and off by the oscillation signal, and accordingly the lamp [7] also repeatedly flashes at a high speed, and the brightness is lowered from the full light state to a constant brightness and is dimmed (dimmed).
enter the state.

Next, when the pair of electrodes (1) is touched again for the third time, this is similarly detected by the touch sensor circuit (2) and its detection output is supplied to the switch circuit (3). The switch circuit (3) then forms an off signal in response to the detection output, thereby making the dimming oscillator (8) inactive and turning off the transistor (6). As a result, the lamp (7) is turned off.

In addition, when the full light state or dimming state is reached, the switch circuit (
The counter of the frequency divider (9) starts counting the clock signal from the oscillator (8) according to the command from the frequency divider (3), and when it has counted for a predetermined period of time, for example, 3 to 4 minutes, it generates an output signal (carry) and starts counting the clock signal from the oscillator (8). ) and switch circuit (3
) generates an off signal to automatically turn off the lamp (7).

Figure 7 shows an example of the specific circuit configuration.
In the figure, parts corresponding to those in Figure 3 are given the same reference numerals.
A detailed explanation thereof will be omitted.

Here, the preset terminal PR of the DFF circuit (33) is connected to the positive side of the DC power supply (11), and the
) is connected to the anode side of the diode (81) of the dimming oscillator (8) and also to the clear terminal CLR of the frequency divider (9). Further, the frequency division output terminal DV of the frequency divider (9) is connected to the clear terminal CLR of the DFF circuits (33) and (34) via an inverter (old).

Further, the output side of the dimming oscillator (83), that is, the output side of the inverter (83), is connected to the oscillation input terminal 0■ of the frequency divider (9). Also, the diode (41) of the OR circuit (4)
The anode side of and (42) is connected to the base of the transistor (52) via the resistor (56), and the transistor (
The emitter of 52) is connected to the positive side of the DC power supply (11), and its collector is connected to the base of the transistor (6) via a resistor (55). In addition, the transistor (5
2) is connected to the DC power supply (11) via the resistor (51).
) to the positive side. The other configurations are the same as in FIG. 3.

Next, the operation of FIG. 7 will be explained with reference to the signal waveform of FIG. 8.

Now, if you touch the pair of electrodes (1) with your hand to short-circuit them at time t1 in FIG. 8, that is, the first touch, the resistance value between them will decrease and the touch sensor circuit (2)
The base potential of the transistor (24) becomes low 1, and the transistor (24) turns on. Then, a signal is obtained on the collector side of the transistor (24), which is waveform-shaped by the inverters (31) and (32) of the switch circuit (3), and a signal as shown in FIG. 8A is generated on the output side. A pulse signal S la is obtained. This pulse signal Sla is supplied to the clock terminals CK of the DFF circuits (33) and (34), and as a result, the output signal S2 of the output terminal Q of the DFF circuit (33) is at a low level ( The inverted output signal S changes from low level to low level (H) as shown in FIG. 8C, and similarly,
The output signal S4 of the output terminal Q of the DFF circuit (34) changes from low level to high level as shown in Figure 8, and the output signal S of the inverted output terminal changes to high level as shown in Figure 8E. level changes to low level.

When the inverted output signal S3 of the DFF circuit (33) becomes low level, the diode (41) of the OR circuit (4)
is turned on, and the transistor (52) is turned on. As a result, the transistor (6) turns on and the lamp (7) lights up, resulting in an all-party state. That is, the first touch of the electrode (1) causes the lamp (7) to enter the full state.

At this time, the inverted output signal S of the DFF circuit (34).

When the voltage becomes low level, the diode (81) is turned off and the dimming oscillator (81) is activated, generating an oscillation signal with a predetermined pulse width. The signal that continuously passes through the diode (41) has priority over the signal that is turned on and off (1), and as a result, the lamp (7) is maintained in the full state.

Next, when the pair of electrodes (1) is touched a second time at time t2 in FIG. 8, a transistor (24) is formed as described above.
is turned on, and a pulse signal -11zb as shown in FIG. 8A is obtained at the output side of the inverter (32). This pulse signal Slb is supplied to the clock terminals CK of the DFF circuits (33) and (34), and as a result, although the output signal S and the inverted output signal Ss of the DFF circuit (34) remain unchanged, the DFF circuit (33) ) output terminal S of output terminal Q
2 changes from high level to low level as shown in FIG. 8B, and the inverted output signal S of the inverted output terminal changes from low level to high level as shown in FIG. 8C.

When the output signal S of the DFF circuit (33) becomes high level, the diode (41) of the OR circuit (4) is turned off. On the other hand, since the inverted output signal SS of the DFF circuit (34) maintains a low level, the oscillator (8) continues to oscillate, and the output side of the inverter (83) is shown in FIG. An oscillation signal having a predetermined pulse width is generated. When the oscillation signal is at a low level, the diode (42) is turned on, transistors (52) and (6) are turned on, and the lamp (7) is lit, but when the oscillation signal is at a high level, the diode (42) is turned off. Then transistors (52) and (6) turn off and lamp (7)
goes out. In other words, the lamp (7) is turned off in the high-level section T in Figure 5, and the lamp (7) is turned on in the low-level section T2, and by repeating this state, the brightness becomes darker than in the all-party state. A so-called dimming state can be maintained. That is, the second touch of the pair of electrodes (1) causes the lamp (7) to enter the dimming state. Also in this case, by arbitrarily setting the sections T and T2, it is possible to adjust the light to an appropriate brightness.

Next, at time t3 in FIG. 8, a third electrode is applied to the pair of electrodes (1).
When you touch it for the second time, the transistor <24> appears as above.
is turned on, and a pulse signal Sle as shown in the eighth prisoner is obtained on the output side of the inverter. This pulse signal Slc is supplied to the clock terminals CK of the DFF circuits (33) and (34), and as a result, the output signal S2 of the DFF circuit (33)
is at a low level as shown in Figure 8, and its inverted output signal S is held at a high level as shown in Figure 8C, but the output signal S of the DFF circuit (34) is as shown in Figure 8. As shown in FIG. 8, the inverted output signal S changes from the low level to the high level as shown in FIG. 8E.

When the inverted output signal S5 of the DFF circuit (34) becomes a zero level, the diode (81) is turned on and the oscillator (8) stops operating. As a result, the lamp (7) goes out. In other words, the lamp (7) is turned off by the third touch on the pair of electrodes (1).

On the other hand, in the full light state when the pair of electrodes (1) is touched for the first time or the dimming state when the pair of electrodes (1) is touched for the second time, the lamp (7) automatically turns off after a predetermined period of time has elapsed. 1) When the inverted output signal S of the DFF circuit (34) becomes low level with the first touch, the counter of the frequency divider (9) is cleared and starts counting the oscillation signal from the oscillator (8). When a predetermined time, e.g. 3 to 4 minutes, has elapsed after counting up, the output of the frequency division output terminal DV goes from low level to a noise level, which is inverted by the inverter (91) and output to the DFF circuits (33) and (34).
) is supplied to the clear terminal CLR of the DFF circuit (33
) and (34) are initialized, so the lamp (7) is automatically turned off at that point.

Note that at the time when the pair of electrodes (1) is touched for the second time and the pulse signal Slb is generated, the inverted output signal S of the DFF circuit (34) is supplied to the clear terminals CL and H of the frequency divider (9). , remains at a low level, so in the dimming state, a predetermined period of time e.g. 3 to 4 minutes has elapsed in total from the time of the first touch, not from the time of the second touch. Then, the lamp (7) will be turned off.

In this way, substantially the same effects as in the first embodiment can be obtained in this embodiment, and furthermore, since the dimming oscillator (8) also serves as the oscillator (10) in this embodiment,
There is an advantage that the circuit configuration can be simplified.

FIG. 9 shows a third embodiment of the present invention. In this embodiment, a charging circuit (100) is connected to a DC type i1'N (11).
This charging circuit (100) has a power transformer (101) and a rectifier diode (1
02>, (103), a resistor (104) and a diode (105) forming a current reducing circuit that adjusts to the rated charging current of the power source (battery) used.

In this embodiment, since the same battery can be used by charging it many times, it is convenient to save the trouble of replacing the battery.

Figure 1O shows an external power jack (111) connected to a DC power supply (11) through a current reduction circuit 15 (112) consisting of a resistor (112a) and a diode (112b) that are used in accordance with the rated charging current of the current used. Connect the external power adapter (114) to this jack (111).
) By plugging in the plug (113) and charging it, the same battery can be used many times, and this embodiment can also obtain substantially the same effects as in FIG. 9.

In addition, in the above-mentioned embodiment, the present invention is similarly applicable to the case where the dimming state is switched in multiple stages.
