Description

The present invention relates to an electronic thermometer.

  The electronic thermometer is configured to measure a body temperature using a thermal sensor, detect an equilibrium temperature regarded as a body temperature, and notify / display it. Such an electronic thermometer automatically determines the end of measurement at the time of body temperature measurement. When the measurement is determined to end, the electronic thermometer notifies the end of measurement and displays the detected temperature as a body temperature. Measurements can be made.

  As a method for determining the end of measurement, a method for determining the end of measurement when it is detected that the measurement temperature is constant for a predetermined period, a method for determining the end of measurement when a predetermined time elapses by measuring with a timer, and a temperature rise for a predetermined period A method for determining the end of measurement when there is no error has been proposed.

  In addition to notifying the end of measurement, an abnormality is detected during measurement, and the end of normal measurement is distinguished from the abnormality in the measurement state that requires re-measurement. In addition, electronic thermometers have been proposed that continue to measure until the automatic erasure time has elapsed. (For example, see Patent Document 1)

Also, in order to facilitate body temperature measurement of infants and infants, the measurement circuit starts from a predetermined time before the body temperature measurement starts until the predetermined time elapses, and until the predetermined time elapses after the body temperature measurement is finished. In the meantime, an electronic thermometer has also been proposed in which sound recorded in a ROM is output to a speaker. (For example, see Patent Document 2)
JP-A-10-253464 Japanese Utility Model Publication No. 06-30738

  As described above, some electronic thermometers equipped with a notification device continuously perform a measurement operation even during a notification operation. Normally, the driving source of a measuring device that measures body temperature and the driving source of a notification device that drives a speaker or the like to output a buzzer sound, a melody sound, or a sound recorded in a ROM are required to have a small electronic thermometer. Therefore, the same power source is used without preparing a power source individually.

  In general, a small battery such as a button battery is used as a power source used for a small device such as an electronic thermometer in consideration of convenience. Since the output capacity of such a battery is not so large, when the measurement operation and the notification operation are performed at the same time, the rate at which the battery voltage decreases is larger than when each operation is performed individually.

  Therefore, if the notification device outputs a buzzer sound, a melody sound, or a sound while the measuring device is measuring the body temperature, the battery voltage is thereby lowered, which may affect the measurement accuracy of the body temperature by the measuring device.

  When outputting the sound recorded in the ROM, it may be known in advance when the sound is output. In such a case, measurement is performed by setting the operation timing in advance so as not to output the sound during measurement. It is also conceivable that the operation and the notification operation are not performed simultaneously.

  However, the notification device using the ROM has a feature that the melody can be changed by exchanging the ROM. When the ROM is exchanged in this way, a time zone in which the measurement operation and the notification operation overlap occurs due to the difference in the length of the melody recorded in the ROM, which may affect the measurement accuracy.

  For example, when the end of measurement is notified by the melody sound recorded in the ROM and the measurement is restarted after the melody sound ends, the melody notification is issued if the melody before replacement is longer than the notification time of the melody after replacement. The measurement operation is resumed before the end, and the measurement operation and the notification operation are performed simultaneously.

  In order to solve the problem due to the ROM exchange, it is necessary to design and reset the operation timing so that the measurement operation and the notification operation do not overlap each time the ROM is exchanged. In order to perform redesign and resetting of the operation timing at the manufacturing stage, it is necessary to re-create the control program and write the re-created control program to the control memory. .

  Therefore, the present invention aims to solve the conventional problems and to prevent simultaneous execution of the measurement operation and the notification operation in the electronic thermometer performing the notification operation, and to prevent a decrease in measurement accuracy due to a decrease in battery voltage. And

  The electronic thermometer of the present invention is an electronic thermometer comprising a measuring device for measuring body temperature, a notifying device for notifying, and a control circuit for controlling the measuring operation and the notifying operation. Measurement operation is performed after detecting.

  Here, the measurement device includes a sensor for measuring body temperature and a measurement circuit for measuring body temperature based on the sensor output, and the measurement circuit can be configured by a CPU and a program.

  The recording device is a device that records auditory information such as a melody sound, a buzzer sound, or a voice, and notification data of visual information such as an image, and may be a melody IC or a ROM, for example.

  The notification device is a device that performs notification using data recorded in the recording device, and can be a speaker that outputs a buzzer sound, a melody sound, or a sound, or a display device that displays image data such as an image.

  The control circuit controls the measurement operation of the measurement device and also controls the notification operation of the notification device.

  The control circuit includes a control mode in which the measurement operation is started after the notification operation is completed, and a control mode in which the notification operation is started after the measurement operation is stopped.

  In the control mode in which the measurement operation is started after the notification operation is completed, for example, a notification by a melody or the like is performed after the electronic thermometer is turned on, and the measurement is started during the measurement or the measurement is started during the measurement. Is stopped, the notification operation is started, and the measurement operation is restarted after the notification operation is completed.

  Further, in the control mode in which the notification operation is started after the measurement operation is stopped, there is a mode in which the notification operation is performed after the measurement operation is stopped due to an equilibrium state of the measurement value or a sudden change.

  In order to perform the operation control at each time point described above, the control circuit can perform the stop control of the measurement operation of the measurement device and the start control of the notification operation of the notification device based on the measurement value condition and the switch operation. Further, the start control of the measurement operation of the measurement device is performed based on the stop of the drive signal from the drive device that outputs the drive signal for driving the notification device.

  When performing the resumption control of the measurement operation of this measurement device based on the stop of the drive signal from the drive device, the control circuit feeds back the drive signal output from the drive device, and the time width during which the fed back drive signal is zero Is detected, it is determined that the operation of the notification device has stopped when the time width exceeds the predetermined time width, and the restart of the measurement operation of the measurement device is controlled.

  Thus, for example, when a melody signal that emits a melody is output from the drive device by the notification device, the control circuit feeds back the melody signal and detects that a predetermined time has elapsed since the melody signal was not output. Then, it is determined that the notification operation has been completed, and control for restarting the measurement operation is performed.

  In addition, the measurement value condition for performing the stop control of the measurement operation of the measurement device and the start control of the notification operation of the notification device can be a plurality of modes.

  The first aspect of the measurement value condition is the measurement value equilibrium detection by the measurement device. The measurement value equilibrium detection is to detect that the measurement value has reached a stable state. In this mode, the equilibrium temperature, which is regarded as the body temperature, is detected. Since the change in the measured temperature is expected to be slight after this equilibrium detection, the power supply to the measuring device is stopped and the measuring device is temporarily stopped. There is no problem in measurement even if it stops. At this time, power is supplied to the notification device, and a notification operation by the notification device is performed. Thereby, simultaneous execution with a measuring apparatus and an alerting | reporting apparatus can be avoided.

  The second aspect of the measurement value condition is detection of steep fluctuations in the measurement value of the measurement apparatus. The second mode is to detect a measurement failure due to the occurrence of some abnormality, and after detecting the occurrence of the abnormality, even if the power supply to the measurement device is stopped and the measurement device is temporarily stopped, the measurement is hindered. There is no. At this time, power is supplied to the notification device, and a notification operation by the notification device is performed. Thereby, simultaneous execution with a measuring apparatus and an alerting | reporting apparatus can be avoided.

  The change detection of the measurement value can be a variation rate of the measurement value or a change amount of the measurement value within a predetermined time. The equilibrium detection according to the first aspect can be detected when the variation rate of the measurement value is equal to or less than the set value and the change amount of the measurement value within a predetermined time is equal to or less than the set value.

  In addition, the steep fluctuation detection of the measurement value of the second aspect can be detected when the fluctuation rate of the measurement value is greater than or equal to the set value and the change amount of the measurement value within a predetermined time is greater than or equal to the set value. it can.

  Further, the stop control of the measurement operation of the measurement device and the start control of the notification operation of the notification device can be performed by a predetermined operation of an operation switch such as a power switch.

  Moreover, about the stop of alerting | reporting operation | movement of an alerting | reporting apparatus can also be made into several aspects.

  The first mode of stopping the notification operation is performed by a predetermined operation, and the control circuit stops the notification operation based on a control signal by the predetermined operation. The predetermined operation can be a switch operation, for example.

  The second mode of stopping the notification operation is performed by stopping the output of the drive signal based on the control signal according to the first mode. The control circuit stops the notification operation by stopping the output of the drive signal of the drive device or stopping the drive of the notification device based on the control signal.

  Furthermore, the electronic thermometer of the present invention can restart the measurement after stopping the measurement operation of the measurement device. The control circuit restarts the measurement by the measuring device after the notification operation is stopped. This prevents simultaneous execution of the measurement operation and the notification operation.

  Further, when a control signal due to a predetermined operation is generated while the notification operation is stopped, the control circuit ends the measurement operation of the measurement device based on the control signal. The predetermined operation can be performed by opening / closing an operation switch such as a power switch.

  According to the present invention, in an electronic thermometer that performs a notification operation, simultaneous execution of a measurement operation and a notification operation can be prevented.

  Further, by preventing simultaneous execution of the measurement operation and the notification operation, it is possible to prevent a decrease in measurement accuracy due to a decrease in battery voltage.

  In the electronic thermometer of the present invention, the notification sound and the notification image can be changed by exchanging the melody IC and the like. At this time, even if the sound output time of the notification sound or the image signal time of the notification image changes, the notification operation such as the melody output or the image output and the measurement operation are not performed at the same time. can do.

  Hereinafter, the electronic thermometer of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic block diagram for explaining a schematic configuration of an electronic thermometer of the present invention. In FIG. 1, an electronic thermometer 1 includes a measurement control circuit 2, a sensor 6 for detecting body temperature, a display device 10 for displaying measured body temperature and other information, a notification device 9 for performing a notification operation, and a notification device. And a switch device 7 such as a power switch or an operation switch.

  The measurement control circuit 2 performs a measurement device 3 that measures body temperature based on a detection signal of a sensor 6 including a thermal element such as a thermistor, a measurement operation of the measurement device 3, and a notification operation of the drive device 8 and the notification device 9. Control so that both operations are not executed simultaneously. The measurement control circuit 2 also includes a timer 5 for control processing.

  The notification device 9 includes a sound generation device that generates sound information such as a buzzer sound and a melody sound. In the case where notification is performed using characters, pictures, or images, an image display device that displays image data can be provided. The display device 10 is a display portion that displays the measured body temperature. The display device 10 and the image display device can share the same display device.

  The drive device 8 outputs a drive signal for driving the notification device 9. When a melody is used for notification, a semiconductor device called a melody IC can be used. A ROM or the like may be used. When image data is recorded in the ROM, a moving image can be displayed on the image display device of the notification device 9 or the display device 10. The image data may be a moving image in addition to a still image.

  In the melody IC, the melody IC as a whole constitutes a drive device, converts the melody waveform of the digital data read from the built-in melody storage unit into analog and outputs it as a drive signal, and stores the melody in the melody IC. A melody storage unit and a drive device unit may be provided, and a melody waveform of digital data read from the melody storage unit may be converted to analog by the drive device unit and output as a drive signal.

  The control circuit 4 feeds back a drive signal that is an output signal of the drive device 8 and determines whether or not the notification operation by the notification device 9 is finished by monitoring the feedback drive signal. can do.

  Next, an operation example of the electronic thermometer of the present invention will be described using the flowchart of FIG.

  The electronic thermometer 1 starts measuring the body temperature in response to the operation of the power switch or the measurement start switch (step S1), and displays the measured value on the display device 10 (step S2).

  The control circuit 4 determines whether or not the measured value has reached a stable state. Whether or not the measured value has reached a stable state can be determined from, for example, the rate of change of the measured value, and when the rate of change is less than a predetermined value set in advance, the measured value becomes stable. It can be determined that it has been reached. The measured value at this time represents an equilibrium temperature regarded as a body temperature. In addition, you may perform determination of a stable state with the measuring apparatus 3 (step S3).

  When the measured value is in a stable state, the measured value is displayed as an equilibrium temperature, assuming that the temperature measurement is completed. Moreover, you may display on the display apparatus 10 that temperature detection was completed (step S4). When the temperature measurement is completed, the control circuit 4 interrupts the measurement operation by the measurement device 3 (step S5) and sends a trigger signal to the drive device 8 (step S6). Here, a case will be described as an example where melody data is recorded in the drive device 8 and notification is performed using a drive signal obtained by analog conversion of the melody data.

  Upon receiving the trigger signal, the driving device 8 (melody IC) generates a driving signal based on the recorded notification data (melody data), and sends the driving signal to the sound generator of the notification device 9 to generate a melody. Let Further, the drive device 8 sends notification data to the notification device 9 and also feeds back a drive signal to the control circuit 4. The control circuit 4 detects that the drive signal fed back from the drive device 8 does not change for a predetermined time, and monitors whether the feedback signal is in a continuous state.

  Here, the continuing feedback signal indicates that a driving signal is sent to the notification device 9 to perform a notification operation. On the other hand, the fact that the feedback signal is stopped indicates that the transmission of the drive signal to the notification device 9 is stopped and the notification operation is stopped.

  Note that whether or not the feedback signal is in the continuous state can be determined by detecting whether or not the state in which the drive signal to be fed back does not change continues for a predetermined time. By detecting that the time when the drive signal does not change exceeds a predetermined time, it is possible to prevent erroneous determination due to the silent time included in the melody signal (drive signal). Can do. The predetermined time can be arbitrarily set, for example, 2 seconds or 3 seconds.

  For example, the control circuit 4 inputs an analog melody signal output from the driving device 8 to the notification device 9 and A / D converts the melody signal into a digital signal. The level of the digital signal is, for example, a low level. If it continues for a predetermined time, it is determined that the notification operation has been completed. The signal level is not limited to the low level, but can be a high level or an intermediate level between the high level and the low level, and a notification is given when a state in which the signal level does not change at a constant level continues for a predetermined time. The condition for determining the end of the operation is used (step S7).

  If it is determined in step S7 that the feedback signal is not continued, the transmission of the drive signal to the notification device 9 is stopped, and the notification operation by the notification device 9 is finished, the control circuit 4 determines that the measurement has been interrupted. The measurement operation by the apparatus 3 is resumed.

  As described above, the control circuit 4 controls the measurement device 3 so that the measurement operation of the measurement device 3 is resumed after the notification operation of the notification device 9 is completed, so that the measurement operation and the notification operation are performed simultaneously. There is nothing (step S8).

  The restarted measurement operation is automatically stopped after a predetermined time has elapsed (steps S9 and S11), and is stopped by turning off the power switch (steps S10 and S11).

  Further, in the determination of the stable state in the step S3, if the measured value falls below a predetermined value set in advance before reaching the stable state, it is determined that an abnormality has occurred in the measurement. To do. This is usually based on the fact that the measured value rises after the start of measurement and reaches a stable state, and the measured value does not drop significantly during this measurement.

  Therefore, when the measured value falls below a predetermined value, it is determined that an abnormality has occurred in the measurement (step S12), the control circuit 4 interrupts the measurement of the measuring device 3 (step S13), and the melody IC. A trigger signal is sent to the driving device 8 (step S14).

  Thereafter, in the same manner as in steps S7 and S8, the driving device 8 (melody IC) that has received the trigger signal sends the recorded notification data (melody data) to the sound generator of the notification device 9 to send a melody. Is generated. Further, the drive device 8 sends notification data to the notification device 9 and also feeds back a drive signal to the control circuit 4. The control circuit 4 detects a change in the drive signal fed back from the drive device 8 and monitors whether the feedback signal is in a continuous state (step S15).

  If it is determined in step S15 that the feedback signal is not continued, the transmission of the drive signal to the notification device 9 is stopped, and the notification operation by the notification device 9 is completed, the control circuit 4 determines that the measurement was interrupted. The measurement operation by the apparatus 3 is resumed (step S16).

  After the measurement is resumed, the measurement value returned to step S2 is displayed on the display device 10, and the same processing is performed thereafter.

  Hereinafter, the measurement operation and the notification operation by the electronic thermometer of the present invention will be described with reference to FIGS. 3 shows an operation example in which the measurement operation is stopped and the notification operation is started when the measurement temperature reaches a stable state, and FIG. 4 shows that the measurement operation is stopped when the measurement temperature is greatly reduced. The operation example which starts notification operation | movement is shown. 3, (a) is a power on / off state, (b) is a change in measured temperature, (c) is a flag indicating a stability detection state, and (d) is a trigger output from the control circuit to the drive device. (E) is a drive signal output sent from the drive device to the notification device, and (f) is a measurement flag indicating the measurement state of the measurement device. 4, (a) is a power on / off state, (b) is a change in measured temperature, (c) is a flag indicating a stable detection state, (d) is a temperature drop detection, and (e) is a control. A trigger signal output from the circuit to the driving device, (f) represents a driving signal output sent from the driving device to the notification device, and (g) represents a measurement flag representing a measurement state of the measuring device.

  First, an operation example in which the measurement operation is stopped and the notification operation is started on the condition that the measurement temperature is stable will be described with reference to FIG.

  In FIG. 3, after the measurement is started (the measurement flag in FIG. 3 (a) is on), the measurement temperature rises and becomes a stable state (A in FIG. 3 (b)). When the measuring device or the control circuit detects this stable state, it determines that the temperature has been detected, turns on the stable detection state flag (on state in FIG. 3 (c)), and displays this measured temperature as an equilibrium temperature. Display on the device. Further, the measurement flag is turned off, and the measurement operation in the measurement apparatus is stopped (B in FIG. 3 (f)).

  Further, the control circuit sends a trigger signal (trigger output in FIG. 3D) to the driving device based on the detection of the stable state. The drive device that has received the trigger signal starts outputting the drive signal formed based on the recorded notification information to the notification device (C in FIG. 3E). Here, for example, a melody signal having a time width T1 is output (output in FIG. 3E).

  The control circuit feeds back the notification information (output of FIG. 3 (e)), and after the notification information is not output (time D in FIG. 3 (e)), the time T0 passes (FIG. 3 ( It is monitored whether a drive signal is output until time E) of e). When the drive signal is not detected during this time T0, it is determined that the output of the drive signal is completed and the notification operation is completed, and the measurement flag that has been turned off is turned on (see FIG. 3F). F) Restart the measuring operation of the measuring device.

  Therefore, when the notification operation of the notification device (FIG. 3 (e)) and the measurement operation of the measurement device (FIG. 3 (f)) are compared, there is no overlap in the operation time of both, and they are not executed simultaneously.

  Next, an example of operation for stopping the measurement operation and starting the notification operation on condition that the measured temperature has greatly decreased will be described with reference to FIG.

  In FIG. 4, after the measurement is started (the measurement flag in FIG. 4A is on), the measurement temperature rises. If the temperature drops significantly during this temperature rise (G in FIG. 4B), the measuring device or the control circuit detects this temperature drop (H in FIG. 4D), and the control circuit is abnormal. Judge that it was done. At this time, the control circuit may display the occurrence of abnormality on the display device. Further, the measurement flag is turned off, and the measurement operation in the measurement apparatus is stopped (I in FIG. 4G).

  Further, the control circuit sends a trigger signal (trigger output of FIG. 4E) to the driving device based on the detection of the temperature drop. Upon receiving the trigger signal, the drive device starts outputting the drive signal formed based on the recorded notification information to the notification device (J in FIG. 4 (f)). The notification information at this time can be different from the notification information when the temperature detection is completed, and can be, for example, another melody data. Here, the time width of the drive signal formed from the notification information (melody data) is, for example, T2 (output in FIG. 4 (f)).

  The control circuit feeds back the drive signal (output of FIG. 4 (f)), and after the drive signal is not output (time K in FIG. 4 (f)), the time T0 elapses (FIG. 4 (f)). It is monitored whether or not a drive signal is output until f). When the drive signal is not detected during this time T0, it is determined that the output of the drive signal is completed and the notification operation is completed, and the measurement flag that has been turned off is turned on (see FIG. 4G). M), restarting the measuring operation of the measuring device. The time width T0 is the same time width as that of the operation example shown in FIG. 3, but may be a different time width.

  When the body temperature is normally measured after the measurement operation is resumed, the same operation as shown in FIG. 3 is performed. Here, since it is the same operation | movement, description is abbreviate | omitted.

  Therefore, when the notification operation of the notification device (FIG. 4 (f)) and the measurement operation of the measurement device (FIG. 4 (g)) are compared, there is no overlap in the operation time of both, and they are not executed simultaneously.

  Next, an operation example when a predetermined operation is performed while the electronic thermometer is turned on will be described with reference to the flowchart of FIG. Here, the predetermined operation is, for example, an operation of pressing an operation button provided in the electronic thermometer, and the power button can also be used as the operation button.

  The electronic thermometer of the present invention can stop the notification operation during a notification operation by a predetermined operation, can stop the measurement during the measurement, and can stop the measurement during the measurement. Measurement can be started.

  In the flowchart of FIG. 5, when a predetermined operation is performed (step S21), the control circuit determines whether a feedback signal is received from the drive device during the predetermined operation (step S22).

  In this determination, when the feedback signal is detected and it is determined that the notification operation is being performed, the control circuit stops the notification operation. The notification operation can be stopped by control for stopping data output from the drive device or control for stopping the operation of the notification device (step S23).

  After stopping the notification operation, the measurement flag is turned on to start the measurement operation by the measurement device (step S24).

  Therefore, according to this operation, for example, when a melody is played as a notification operation, the melody can be stopped.

  If it is determined in step S22 that the feedback signal is not detected and the notification operation is not being performed, the measurement flag is determined (step S25). In the determination of the measurement flag, if the measurement flag is on, the measurement flag is turned off and the measurement is terminated (step S26).

  Therefore, the measurement can be ended by performing this operation during the measurement.

  Further, in the determination of the measurement flag in step S25, when the measurement flag is in the off state, the measurement flag is turned on and the measurement is started (step S27).

  Therefore, measurement can be started by performing this operation during non-measurement.

  Next, an operation example for stopping the above-described notification operation will be described with reference to FIGS. This operation example is an operation example corresponding to a sound stop operation when a melody is sounded by a notification operation.

  FIG. 6 shows an operation example in which the notification operation is stopped by a predetermined operation and the measurement operation is stopped while the notification operation is performed by a normal measurement operation.

  In FIG. 6, (a) is a power on / off state, (b) is a change in measured temperature, (c) is a flag indicating a stability detection state, (d) is a trigger signal output from the control circuit to the drive device, (E) is a notification data output sent from the driving device to the notification device, (f) is a predetermined operation, and (g) is a measurement flag indicating the measurement state of the measurement device.

  FIG. 6 shows an example in which the measurement operation is stopped and the notification operation is started on the condition that the measured temperature has reached a stable state, and a predetermined operation is performed during the notification operation.

  In FIG. 6, after the measurement is started (the measurement flag in FIG. 6 (a) is in the on state), the measurement temperature rises and becomes a stable state (A in FIG. 6 (b)). When the measuring device or the control circuit detects this stable state, it determines that the temperature has been detected, turns on the stable detection state flag (on state in FIG. 6C), and displays this measured temperature as an equilibrium temperature. Display on the device. Further, the measurement flag is turned off to stop the measurement operation in the measurement apparatus (B in FIG. 6G).

  Further, the control circuit sends a trigger signal (trigger output in FIG. 6D) to the driving device based on the detection of the stable state. Upon receiving the trigger signal, the drive device forms a drive signal based on the recorded notification information, and starts outputting the formed drive signal to the notification device (C in FIG. 6E). The above operation is the same as in FIG.

  When a predetermined operation is performed while the drive signal is output and the notification operation is performed (N in FIG. 6F), the control circuit controls the drive device to transmit the notification information to the notification device. The output is stopped (O in FIG. 6E).

  Further, the control circuit sets the measurement flag that has been turned off to the on state (P in FIG. 6G), and restarts the measurement operation of the measurement apparatus.

  After that, when a predetermined operation is performed again (Q in FIG. 6 (f)), the control circuit turns off the measurement flag that has been turned on (R in FIG. 6 (g)), and ends the measurement operation of the measurement apparatus. .

  Next, FIGS. 7 and 8 are examples in the case where the measurement operation is stopped and the notification operation is started on the condition that the measured temperature is greatly lowered, and a predetermined operation is performed during the notification operation.

  In FIG. 7, after the measurement is started (the measurement flag in FIG. 7A is on), the measurement temperature rises. If the temperature drops significantly during this temperature rise (G in FIG. 7B), the measuring device or control circuit detects this temperature drop (H in FIG. 7D), and the control circuit is abnormal. Judge that it was done. At this time, the control circuit may display the occurrence of abnormality on the display device. Further, the control circuit turns off the measurement flag and stops the measurement operation in the measurement apparatus (I in FIG. 7 (h)).

  Further, the control circuit sends a trigger signal (trigger output of FIG. 7 (e)) to the driving device based on the detection of the temperature drop. Upon receiving the trigger signal, the drive device starts outputting the drive signal formed based on the recorded notification information to the notification device (J in FIG. 7 (f)). The above operation is the same as in FIG.

  When a predetermined operation is performed while the notification information is output and the notification operation is being performed (S in FIG. 7G), the control circuit controls the drive device so that the notification information to the notification device is displayed. The output is stopped (T in FIG. 7 (f)).

  In addition, the control circuit turns on the measurement flag that has been turned off (U in FIG. 7H), and restarts the measurement operation of the measurement apparatus.

  When the body temperature is normally measured after the measurement operation is resumed, the same operation as shown in FIG. 3 is performed. Here, since it is the same operation | movement, description is abbreviate | omitted.

  In the operation example of FIG. 8, when the notification operation is stopped and the measurement operation is restarted (S, T, U in FIG. 8) in the operation example of FIG. 7, a predetermined operation is performed again (FIG. 8 (g ) V), the control circuit turns off the measurement flag that has been turned on (W in FIG. 8H), and ends the measurement operation of the measurement apparatus.

  As described above, with reference to FIG. 2 to FIG. 4 and FIG. 6 to FIG. As described above, the present invention performs a notification operation when starting the measurement operation by pressing the power switch from the state where the measurement operation is completed, and starts the measurement operation after detecting the end of the notification operation. You may do it.

  For example, in the same configuration as in FIG. 1, when the measurement operation is started by pressing the power switch from the state where the measurement operation is completed (FIG. 5, when the measurement flag in step S27 is turned on). The control circuit 4 outputs a trigger signal to the driving device 8 to perform a notification operation. Then, after the drive signal output from the drive device 8 to the notification device 9 is fed back to the control circuit 4, the control circuit 4 detects that the drive signal is not in a continuous state (the drive signal does not change for a predetermined time). Then, the sensor 6 is operated to perform a measurement operation.

  Also in this case, when the operation button is operated during the notification operation, the control circuit 4 can control the drive device 8 to stop the notification operation.

  FIG. 9 is a diagram showing an example of the appearance of the electronic thermometer of the present invention, FIG. 9 (a) shows the front surface, FIG. 9 (b) shows the side surface, and FIG. 9 (c) shows the back surface. .

  The electronic thermometer includes a housing 11 in which each device and circuit shown in FIG. 1 is incorporated, and a sensor cap 13 that protects the sensor is provided at one end of the housing 11, and a battery cover 12 is provided at the other end. Is provided. The portion of the sensor cap 13 is formed thinner than the main body portion of the housing 11. Further, the battery cover 12 can be freely opened and closed, and the battery mounted inside the housing is exchanged.

  A display panel 15 for displaying the measured body temperature and a switch 14 are provided at a substantially central portion of the surface. The switch 14 is used as a power switch and an operation switch.

  A back cover 16 having a buzzer hole 17 is attached to a substantially central portion of the back surface. Note that the appearance of the electronic thermometer shown in FIG. 9 is an example, and other appearances may be used.

  FIG. 10 shows a configuration example in which the measurement operation is stopped by counting the timer. The configuration shown in FIG. 1 is different from the configuration shown in FIG. 1 in that the measurement operation is stopped by the timing signal from the timer 5 without using the feedback signal from the driving device 8. The difference is in the control.

  According to the circuit configuration of FIG. 10, the control circuit 4 performs a measurement operation that has been stopped simultaneously with the start of the notification operation based on the timing of the timer. For example, the continuation time Tm1 of the melody data from the melody ROM 1 in FIG. 11D is set as the time until the measurement is restarted, and the measurement is restarted when Tm1 elapses after the measurement is stopped by the timer. (FIG. 11 (e)).

  FIGS. 11F and 11G show a case where the melody ROM is exchanged. When the melody ROM is changed from the melody ROM 1 to the melody ROM 2 with a long duration (Tm2), if the time until the measurement restart set by the control circuit 4 is kept at Tm1, the melody is output. There is a period in which the measurement operation overlaps, and there is a risk that the measurement accuracy will decrease due to the voltage drop caused by this.

  On the other hand, even if the duration of the drive signal output from the drive data device fluctuates by feeding back and detecting the drive signal output from the drive device and monitoring the notification operation, It is possible to perform operation control without overlapping measurement operations, and it is possible to prevent a decrease in measurement accuracy due to a voltage drop.
