Fig. 3a is a diagram showing a time display pattern, Fig. 5 is a diagram showing a weight display pattern, and Fig. 4 is a control flow chart.

The display screen of the liquid crystal display 13 is divided by the control unit 31 into a main display area 131 at the top of the screen and an auxiliary display area 132 at the bottom of the screen. Predetermined detection data and device status are respectively displayed in the auxiliary display area 132. That is,
The main display area 131 has first to fourth switches 121 to
Any of the time, weight, temperature, and illuminance selected by 124 is displayed. Illuminance data 132a is displayed at the upper left of the auxiliary display area 132, and temperature data 132b is displayed at the upper right.
However, an illuminance mark 132C is displayed at the lower left, a clock mark 132d is usually displayed at the lower center, and a card confirmation mark 132e is displayed at the lower right. Further, when the display of weight is selected by the second switch 122, the clock mark 132d changes to a scale mark 132f. Further, when the audio memory card 20 is not inserted into the connector 16, the card confirmation mark 132e is not displayed.

Normally, the control section 31 monitors the states of each switch and sensor of the sensor section 12, inputs clock data from a clock counter 36, and displays each data on the liquid crystal display 1'3. Furthermore, the first to fourth switches 121 to 12
The data selected in step 4 is announced by voice.

That is, the control unit 31 receives time data from the time counter 36, temperature data from the A/D converter 33, and A/D.
Input illuminance data from the converter 32 (Sl,
, $2. S3) Next, a display signal is sent to the liquid crystal display 13 to display the time based on the clock data in the main display area 131 and the above-mentioned mark etc. in the auxiliary display area 132.
The data is output to and displayed (S4).

Next, it is determined whether the first switch 121 is turned on (s5). When the first switch 121 is turned on, it extracts the word segment necessary for audibly announcing the time based on the clock data, and outputs voice data to the voice notification section 37 based on this word segment. The time is announced by voice (s6). When the first switch 121 is turned on and the audio memory card 20 is not inserted into the connector 16, only numbers indicating the time are displayed on the liquid crystal display 13. Here, the control section 31 determines the insertion state of the audio memory card 2o into the connector 6 depending on whether a specific terminal of the connector 16 is grounded or not.

If the first switch 121 is not turned on as a result of the determination in S5, it is determined whether the second switch 122 is turned on (s7).

As a result of this determination, when the second switch 122 is turned on, 0 is written to a predetermined data register A (S8
), weight data W1 as a reference for the A/D converter 34
After manually inputting (S9), the weight o grams is displayed in the main display area 131 (Sl, O).

At this time, no object to be measured for the ffi amount is placed on the mounting table 20. After this, the user places the weight Δ on the platform 120.
11 Place the fixed object.

Next, the control unit 31 inputs the weight data W2 from the A/D converter 34) and displays the weight of the object to be measured in the main display area 131 (S12).

At this time, since the weight data W2 may fluctuate due to the pressure of the user's hand, etc., the control unit 31 determines whether the fluctuation of the weight data W2 has stopped (S13).
. As a result of this determination, if the weight data W2 is fluctuating, the process moves to Sll, and if the fluctuation has stopped, it is determined whether the weight data W2 is equal to the weight data W1 (S14). . As a result of this determination, when the weight data W2 is not equal to the weight data W1, that is, when the weight measurement target is placed on the platform 120, the weight data W2
The word segment necessary for vocally announcing the weight based on the word segment is read from the voice memory card 20, and based on the word segment, audio data is output to the voice reporting section 37 to vocally announce the weight (S15). Audio memory card 20 is connected to connector 16
If it is not inserted, only the display will be performed as described above. After this, write 0 to data register A (S
1B), proceed to the processing of the Sit.

If the result of the determination in S14 is that the weight data W2 is not equal to the weight data W1, it is determined whether the value of the data register A is 0 (S i7). As a result of this determination, if the value of data register A is not O, step
The process moves to 0, and when it is 0, the value of data register A is rewritten to 1 (S18).

After that, set the timer provided in the control unit 31)7 (S1
9), it is determined whether the time measured by the timer reaches a predetermined time, for example, 10 seconds (S2(1). As a result of this determination, if the time measured by the timer does not reach the predetermined time, the Sll When a predetermined time has elapsed, the process proceeds to step S1.Here, the time is displayed in the main display area 131 after a predetermined time has elapsed since the object to be measured was removed from the stage 120. Thereby, if the next object to be measured is placed on the mounting table 120 within a predetermined time, the weight can be measured without operating the second switch 122.

If the second switch 122 is not turned on as a result of the determination in S7, it is determined whether the third switch 123 is turned on (S21).

As a result of this determination, when the third switch 123 is turned on, temperature data is input from the A/D converter 33, and the temperature is displayed in the main display area 1'31 for a predetermined period of time based on this temperature data. (S22). Furthermore, the word segment necessary for vocally reporting the temperature is read from the voice memory card 20, and based on this word segment, audio data is output to the voice reporting section 37 to vocally report the temperature (S23).

Here, when the audio memory card 20 is not inserted into the connector 16, only the display is performed as described above.

As mentioned above, the temperature around the housing 11 is determined by the thermistor 12.
6, and this temperature can be easily known.

If the third switch 123 is not turned on as a result of the determination in step 521, it is determined whether the fourth switch 124 is turned on (S24). As a result of this judgment,
When the fourth switch 124 is not turned on, the S1
When the process is turned on, the A/D converter 32
The illuminance data is inputted from , and the illuminance is displayed in the main display area 131 for a predetermined period of time based on this illuminance data (S25
). Furthermore, the word search unit necessary for vocally reporting the illuminance is read from the voice memory card 20, and based on this word segment, audio data is output to the voice reporting unit 37 to vocally report the illuminance (S2B). . At this time, if the audio memory card 20 is not inserted into the connector 16, only the display is performed as described above. In addition, the auxiliary display area 13
Needless to say, the card confirmation mark 132e of No. 2 has disappeared. In this way, the illuminance can be easily measured by placing the housing 11 at a location where the illuminance n1 is desired and allowing light to enter through the window 120a.

As mentioned above, according to this embodiment, one device can:
We have made it possible to measure MI, temperature, and illuminance, which are often needed in daily life, and we have made it possible to display the CI measurement results and notify them by voice, so that even visually impaired people can easily obtain the necessary information. I can do it.

Further, since the measurement results selected by the first to fourth switches 121 to 124 are displayed in the main display area 131 of the liquid crystal display 13, the measurement results can be easily distinguished from other displays and visually recognized.

Furthermore, by exchanging the voice memory card 20, the language of the voice notification can be changed to a language other than Japanese, such as French or English.
Since the language can be changed to German or the like, the user can select a language that the user understands or that suits his or her preferences.

In this embodiment, three physical quantities, weight, temperature, and illuminance, can be measured, and the results of these measurements are displayed and notified by voice. However, other continuously changing physical quantities, such as Sensors for measuring ultraviolet rays, infrared rays, sound ff1 (noise), humidity, atmospheric pressure, etc. may be provided, and the results of these measurements may be displayed and audibly announced.

Furthermore, in this embodiment, the phototransistor 125, the thermistor 126, and the pressure sensor 127 consisting of a strain gauge are used to measure each of the illuminance, temperature, and weight, but the present invention is not limited thereto. For example, it goes without saying that the same effect can be obtained by using a CdS cell, a thermocouple, a capacitive pressure sensor, or the like to set each of the illuminance, temperature, and weight by 111J.

Further, when the audio memory card 20 is not inserted into the connector 16, the first to fourth switches 121 to 12
When any one of 4 is pressed, words indicating that the voice memory card 20 is not inserted may be audibly announced using a word segment set in the program.

(Effects of the Invention) As explained above, according to claim (1) of the present invention, each detection means detects a physical quantity corresponding to these detection means, and the physical quantity is determined based on the selection result by the selection means. Since the notification is made by voice, it is possible to easily determine a plurality of physical quantities using one device. Furthermore, for visually impaired people, there is no need to separately provide special equipment for each physical quantity to be measured.

Further, according to claim (2), in addition to the above-mentioned effects, since the plurality of continuously changing physical quantities as described above are displayed by the display means, the measured physical quantities can be easily recognized visually.

Furthermore, according to claim (3), in addition to the above effects, 10.
Since the physical quantity selected by the selection means is displayed in the main display area of the display screen, it is very advantageous that the necessary information, that is, the selected physical quantity can be easily distinguished from other displays and visually recognized.
