  First, a specific configuration of a weight scale with a simultaneous display function of a plurality of mass units according to the present invention will be described with reference to an external view shown in FIG. 1, a block diagram shown in FIG. 2, and a display screen diagram shown in FIG.

  As shown in FIG. 1, the weight scale with simultaneous display function of a plurality of mass units according to the present invention has a base 1, a cover 2, a leg 3, a start switch 4, a mass unit specifying unit 5 and a display. As shown in FIG. 2, the power supply 7, the power supply circuit 8, the weight sensor 9, the amplifier circuit 10, the A / D converter, the external storage device 12, the buzzer circuit 13, and the microcomputer 14 are configured. It consists of.

  Base 1, cover 2, leg 3, start switch 4, power supply 7, power supply circuit 8, weight sensor 9, amplifier circuit 10, A / D converter, external storage device 12, buzzer circuit 13 and microcomputer 14 are publicly known. Since it is the same as that of the thing comprised by the weight scale, detailed description is abbreviate | omitted.

  The mass unit specifying unit 5 includes an index enumeration unit 5b in which each index indicated by kg (kilogram) notation, lb (pound) notation, st-lb (stone pound) notation, scroll (scroll) notation is listed in a row, The index listing unit 5b includes a changeover switch 5a for specifying any one of the indices listed in a line.

  As shown in FIG. 3, the display 6 has a display screen divided into three sections, one of which is larger than the other two sections. And the display according to the parameter | index specified by the mass unit specific | specification part 5 is performed. For example, when any index (for example, kg) of indices indicating a plurality of different mass units (kg, lb, st-lb) is identified by the mass unit identifying unit 5, the identified index The mass represented by the mass unit (kg) indicating is displayed in a large section, and the mass represented by an unspecified mass unit (lb, st-lb) is displayed in the other section. Further, when an index (scroll) indicating scrolling is specified by the mass unit specifying unit 5, the following display is sequentially performed. First, a mass represented by one mass unit (for example, kg) is displayed in a large section, and a mass represented by another mass unit (lb, st-lb) is displayed in another section. Subsequently, the mass represented by one mass unit (for example, lb) is displayed in a large section, and the mass represented by another mass unit (st-lb, kg) is displayed in another section. Subsequently, the mass represented by one mass unit (for example, st-lb) is displayed in a large section, and the mass represented by another mass unit (kg, lb) is displayed in another section.

The microcomputer 14 includes a CPU, a ROM, a RAM, a timer, an IO port, and the like, calculates a mass expressed in one mass unit based on a detection signal from the weight sensor 9, and calculates the calculated one Conversion from mass units to other mass units is performed based on the following relationship.
1 lb = 14 lb = 0.45359 kg (i)
1st = 6.35kg (ii)

  Next, using the flowchart shown in FIG. 4, the operation of the weight scale with the simultaneous display function of a plurality of mass units having the above-described configuration will be described.

  First, when the start switch 4 is pressed, power is supplied from the power source 7 to each part of each electrical system through the power circuit 8 (step S1), and the index listing unit 5b specified by the changeover switch 5a in the microcomputer 14 is provided. One of the indices listed in (1) (for example, kg) is recognized (step S2).

  Subsequently, a signal when the person to be measured is not on the cover 2 by the weight sensor 9, that is, a zero signal (analog) is detected, the detected zero signal is amplified by the amplifier circuit 10, and the amplified zero signal is amplified. Is digitally converted by the A / D conversion circuit 11 (step S3).

  Subsequently, the microcomputer 14 determines that the digitally converted zero point signal is displayed as a zero value, and controls to display the zero value on each of the three sections of the display (display screen) 6. At this time, the mass (kg) indicating the index specified by the changeover switch 5a is displayed on the large section (upper stage) of the display (display screen) 6 and is not specified by the changeover switch. Control is performed so that the mass represented by the mass unit (lb, st-lb) indicating the index is displayed in other sections (middle, lower). And the indicator 6 performs the display according to control from the microcomputer 14 (step S4).

  Subsequently, in the microcomputer 14, it is determined whether or not the changeover switch 5 a has been switched to change the currently specified index (kg) (step S 5). When the index (kg) is changed (for example, lb) (“Yes” in step S5), the mass represented by the mass unit (lb) indicating the changed index is displayed on the display (display screen) 6. In addition to displaying in the large division (upper), the display of the mass expressed in mass units (st-lb, kg) indicating other indicators is controlled to be displayed in the other division (middle, lower), and the display 6, display is performed in accordance with control from the microcomputer 14. On the other hand, when the index (kg) is not changed (“None” in step S5), the signal from the weight sensor 9 is not changed based on the time measured by the timer in the microcomputer 14 (the person to be measured covers the cover 2). It is determined whether or not the state of not riding on has continued for a certain time (step S6).

  Subsequently, when there is no signal change for a certain period of time ("YES" in step S6), the supply of power from the power source 7 to each part of the electrical system is stopped, and the display (display screen) The display of 6 disappears and the operation of this scale ends. On the other hand, when the state where there is no signal change does not continue for a certain period of time (when the person to be measured gets on the cover 2) ("NO" in step S6), the microcomputer 14 determines the signal change amount from the weight sensor 9 in the microcomputer 14. Capture (step S7).

  Subsequently, the microcomputer 14 obtains a mass represented by one mass unit (for example, kg) based on the signal change amount from the weight sensor 9, and converts this calculation result to obtain another mass. The mass represented by the unit (lb, st-lb) is also obtained (step S8).

  Subsequently, the microcomputer 14 performs control so that the mass represented by each obtained mass unit is displayed on each of the three sections of the display (display screen) 6. At this time, the mass represented by the mass unit (kg) indicating the index specified by the changeover switch 5a is displayed on the large section (upper stage) of the display (display screen) 6 and specified by the changeover switch 5a. Control is performed so that the mass represented by the mass unit (lb, st-lb) indicating the index that is not displayed is displayed in other sections (middle, lower). And the indicator 6 performs the display according to control from the microcomputer 14 (step S9).

  Subsequently, in the microcomputer 14, it is determined whether or not the changeover switch 5a has been switched to change the currently specified index (kg) (step S10). When the index (kg) is changed (for example, lb) (“Yes” in step S10), the mass represented by the mass unit (lb) indicating the changed index is displayed on the display (display screen) 6. In the display unit 6, the display is performed in a large section (upper stage), and the mass represented by the mass unit (st-lb, kg) indicating other indicators is displayed in the other section (middle stage, lower stage). Then, display according to the control from the microcomputer 14 is performed. On the other hand, when the index (kg) is not changed (“None” in step S10), it is determined whether or not the zero signal from the weight sensor 9 (the signal indicating that the person to be measured has descended from the cover 2) has been captured. (Step S11).

  Subsequently, if the zero signal is not captured (“NO” in step S11), whether or not the state in which the signal from the weight sensor 9 has changed continues for a certain time based on the time measured by the timer inside the microcomputer 14. Is determined (step S12). On the other hand, when the zero point signal is captured (“YES” in step S11), the microcomputer 14 controls the display unit (display screen) 6 to display the zero value in each of the three sections. At this time, the mass represented by the mass unit (kg) indicating the index specified by the changeover switch is displayed on the large section (upper stage) of the display (display screen) 6 and the index not specified by the changeover switch 5a is displayed. Control is performed so that the mass represented by the indicated mass unit (lb, st-lb) is displayed in the other sections (middle, lower). And the indicator 6 performs the display according to control from the microcomputer 14 (step S13).

  When the signal change state continues for a certain period of time following step S12 ("YES" in step S12), the supply of power from the power source 7 to each part of the electrical system is stopped, and the display ( Display 6) disappears, and the operation of the apparatus ends. On the other hand, when the state with the signal change does not continue for a certain period of time (“NO” in step S12), the display 6 continuously displays (step S9).

  Subsequently to step S13, based on the time measured by the timer inside the microcomputer 14, it is determined whether or not a state in which there is no signal change from the weight sensor 9 (a state where the person to be measured has descended on the cover 2) has continued for a certain period of time. (Step S14). When the state where there is no signal change from the weight sensor 9 does not continue for a certain period of time (“NO” in step S14), the display 6 continuously displays (step S13). On the other hand, when there is no signal change from the weight sensor 9 for a certain period of time ("YES" in step S14), the supply of power from the power source 7 to each part of the electrical system is stopped, and the display unit (Display screen) 6 disappears, and the operation of the scale is completed (step S15).
