Abstract

PURPOSE:To enable alarming advice, etc. of an approaching person, by allowing a control signal to be generated at the time when the person covers the distance preset and stored by a measured value with a distance sensor accommodated in an electronic clock. CONSTITUTION:For opening of an 'AND' gate 53 by operation of a switch 50, a clock 1 P/M is issued from the gate 53 to be introduced into an 'OR' gate 40. By this arrangement, a signal generator 9 emits a signal once in a minute and upon finding an article such as a person, etc., to be measured at this moment, its reflecting wave is received by a signal receiver 10 and, in the mean time a counting circuit 42 counts time difference between issuing and receiving time of said supersonic wave by said action and further, its counted data is converted into a distance data correspondingly by a converting circuit 49 and given to the other end of a comparator 38. Thus, when its distance data coincide with those preset in a distance storing unit 37 by a dial 4 a comparing circuit 38 issues a signal resulted from comparison of '1' and this signal is given to 'AND' gates 54 and 55. By a switch 56, buzzer 28 or lamp 60 are driven to give alarm.

Next, the operation of the above embodiment will be explained. The oscillation circuit 15 constantly generates a reference chromacus No. 9 signal and supplies it to the frequency divider circuit 16 and the ant gate 48. Then, the frequency dividing circuit 16 obtains a clock signal IP/M with a period of 1 minute from the basic clock signal, and supplies it to the time counter 17 and the pulse motor drive plane P1520.

Note that the operations of correcting the time and date and setting the alarm time using the setting switch 22 are well known, so the details will be explained below)
2. Explanation will be omitted.

Next, the operation when setting an arbitrary distance in the distance storage section 67 will be explained. There are two ways to set this distance.
The ml method is to set the dial 4 to "0" and operate the ¥ release memory switch 5, and the second method is to set the dial 4 to a value other than rOJ and set it directly. ◎In any of these cases, operate the mote changeover switch 29 in advance to switch to the distance setting mode ST.
By setting , the distance set in the distance setting record ff1 section 37 can be displayed on the digital display section 8A. At this time, due to the operation of the selection circuit 31, the distance setting mode (IT) is displayed on the mode degree display section 8B.

In the case of the ml decision, the encoder 62 outputs the signal 1 as “
! ", signal 12 is output as 10". Therefore, the AND gate 55 is opened and the AND gate 55 is closed. Therefore, after pointing the distance sensor 6 of the electronic watch toward the object to be measured, turning on the distance epsilon switch 5 once,
A single signal output from the AND gate 34 sets the flip-flop 41 and clears the counting circuit 42, and the drive circuit 46 drives the transmitter 9 to emit an ultrasonic wave. And the above 7! Since the rough 0 pulse 41 is set, the reference chroma signal from the oscillation circuit 15 is generated in the counting circuit 42.

gate 48Tc- and thus its counting operation is performed.

On the other hand, the transmitted ultrasonic wave is reflected by the object to be measured, and the reflected wave is received by the receiver 10, and then the sense circuit 46
After being amplified by 7 lip-flop 41Tr: reset. Therefore, at the same time, the counting operation of the counting circuit 42 is stopped, and the counted value data is transferred to the converting circuit 42.
9, it can be converted to the corresponding Kobyou data, and the distance record is t11.
section 67.

On the other hand, in the case of the second method, the dial 4 is set to any scale other than "0". At that time, the encoder 32 outputs the signal E1 as the signal E2111m, and the end gate 63.34 closes and the AND gate 65 opens.Then, the encoder 62 further outputs six set distance data D. is sent to the distance record t!2 section 37 via the ant gate 35 and the or gate 36, and the record tXJ
be done. As a result, the distance set using the dial 4 is preset in the distance record tI1 section 37.

The distance data preset by the method of $12 is then given to one end of the comparison zero sweetfish 38, and is also displayed on eight digital display items via the display switching circuit 19.

Like this! 11 After the desired distance has been preset in the distance memory 37, operate the mode switching switch 29 to set the distance jlQ constant mode)-DI, and then press the distance II measurement star)/stop switch 50. If you turn on and set 7 Q buzzer 70 cup 52, when a person approaches the electronic clock and the measured distance reaches the preset distance, the buzzer 28 or 1 = lamp 60 will sound.
to emit an alarm sound, or display part 2.
can be illuminated.

That is, since the AND gate 56 is opened by operating the switch 50, BLACK! The output IP/M is output from the AND gate 53 and input to the output gate 40. Therefore, the transmitter 9 emits an ultrasonic wave once every minute, and if there is an object to be measured such as a person at that time, the reflected wave is received by the receiver 10. The above operation causes the total Wc circuit 42 to reach F+1? The time difference between the transmission and reception of the J3'Ff wave is counted, and the counted value data is converted into corresponding distance data by the conversion circuit 49, and the other end of the comparison mouth trace 38! It can be done.

Therefore, when the distance data matches the preset distance data, the ratio f2 circuit 38 outputs the ratio f2 result signal, and the output gates 54 and 5
Give to 5. Now, if the buzzer is selected by the lamp/buzzer selector switch 56, the T-gate 54 is open and the AND gate 55 is closed, so the comparison result signal of "1" is The signal is input to the buzzer drive circuit 27, so that the buzzer 28 emits an alarm sound and functions as a warning device.

On the other hand, if the lamp is selected by the switch 56, the comparison result signal is input to the lamp drive circuit 59,
Therefore, the lamp 60 is turned on and the display section 2 is illuminated, so that the time can be seen even in a dark place such as at night.

Incidentally, in the above embodiment, the wooden watch 114 is applied to an analog electronic watch, but of course, it may be applied to an electronic watch with a digital display.

Predetermined arbitrary distance storage means, l! 11 distance
A means for emitting a control i signal when the distance determined by measuring 1,000 reaches a set distance in the Rib storage means, a driving means for driving a predetermined driven object f by this split skin signal, and an electronic device with a distance illumination sensor. Since it is a clock, it has the advantage of being able to provide an electronic clock with a new function of measuring distance.In addition, the lamp Pg that illuminates the time display section is used as the driven body.
If you use J, you can reliably check the time by simply holding your hand close to the watch at night, and if you use a buzzer instead of a lamp, you can also use it as an N-information system.
