Abstract

PURPOSE:To make it possible to display the history of the change in body weight from the past and to facilitate health management by providing a slot in which a memory card is removably inserted, and providing a means which transfers the data from a converting part into the memory card. CONSTITUTION:When a person rides on a scale part, the body weight is measured. The corresponding electric signal is outputted from a load cell 18 and inputted into a CPU 11. When a memory card 9 is inserted into a slot, the card is connected to the CPU 11 through an interface 15. The data inputted from the load cell 18 are stored in a RAM 14 together with the time data from a clock circuit 17. The data in the RAM 14 are stored in the memory card 9 by operating a keyboard 6 as required or can be displayed on a display part 5. Thus the history of the change in body weight can be stored.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic scale used for health management.

Conventional technology Nowadays, people are more aware of health issues, and there is a strong sense of caution about being overweight. For this reason, for example, in facilities that place emphasis on health management, such as fitness clubs, a scale 50 is installed as shown in Figure 5, and people's weight is measured on a daily basis to check their health status. There are many.

Problems to be Solved by the Invention With the conventional weight scale 50, only the result at the time of measurement is known, and therefore the data cannot be saved no matter how many times the same person measures their weight. For this reason, it is not possible to store the history of weight changes unless individuals record their weight changes.

Means for Solving the Problem In an electronic scale that has a conversion section that converts a load into an electrical signal and a display that displays data input from this conversion section, a memory card can be detachably attached to a part of the electronic scale. A slot for insertion was provided, and a transfer means for transferring data input from the conversion section to the memory card was provided.

Weight measurement data can be recorded as needed by inserting a memory card owned by the individual into the slot. Furthermore, an internal memory is provided to store the data input from the conversion unit and the data loaded from the memory card as time series data, and by connecting this internal memory to a display, you can see the history of weight changes from the past. This can be confirmed from the display.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 to 4. First, FIG. 1 shows an electronic scale 1.

This electronic scale 1 has a weighing section 2 and an operating section 3 connected by a support 4, and a display 5, a keyboard 6, and an issuing port 8 for issuing a recording paper 7 are arranged on the upper surface of the operating section 3. A slot 10 into which a memory card 9 is inserted is provided on the side.

Next, FIG. 2 shows the electronic circuit. Inside the operation unit 3, there is a CPU II and a ROM in which Pumgram is written.
12 and an internal memory 14 including a RAM 13 into which variable data is written, a memory card interface 15 to which the memory card 9 is connected, and a printer section 16.
Clock circuits 17 are connected to each other. Further, the load cell 18, which is a converter that converts a load into an electric signal, and the keyboard 6 are connected to the input side of the CPU II, and the display device 5 is connected to the output side of the CPU II. The load cell 18 constitutes the main component of the weighing section 2.

In such a configuration, when a person stands on the scale section 2, the weight of the person is applied to the load cell 18, and the load cell 18 outputs an electric signal corresponding to this load. Under the control of the CPU 11, the data input from the load cell 18 is stored in the RAM 14 together with the time data input from the clock circuit 17.
The data in the RAM 13 can be saved in the memory card 9 or displayed on the display 5 if necessary. This usage mode selection will be explained with reference to the flowchart in FIG. First, by turning on the power, it enters the weight measurement mode. Here, when the memory card 9 is inserted into the slot 10, the memory card 9 is connected to the CPU II via the memory card interface 15. When the person's name code is input using the keyboard 6, the data on the memory card 9 is transferred to the internal memory 14.
is loaded into the RAM 13 of. Next, when the data display mode is selected using the keyboard 6 without pressing the end key, the display start date is input based on the data loaded into the RAM 13, and past data is displayed on the display 5. As shown in FIG. 4, this display shows changes in weight measurements in a time-series manner as a graph. Also, when an instruction to print is input using the keyboard 6, the RAM
13 data is printed on the recording paper 7 by the print section 16,
The printed recording paper 7 is issued from the issuing port 8. Also,
If you input the registration mode using the keyboard 6 without selecting the data display mode on the display 5, the data in the internal memory 14, that is, the data in the RAM 13, will be transferred to the memory card 9 as long as the previously input person name code is correct. will be saved. This step is a transfer means that transfers the data input from the load cell 18 to the memory card 9. Subsequently, the data in the RAM 13 is cleared. Here, when the end key is input using the keyboard 6, it is confirmed that the data in the internal memory 14 has been cleared, and the process returns to the next weight measurement mode.

As described above, weight measurement data can be recorded by inserting the personally owned memory card 9 into the slot 10. In addition, if necessary, load cell 18
The data input from the memory card 9 and the data loaded from the memory card 9 are used as time series data to
The history of weight changes from the past is stored in M13 and displayed on display 5.
You can check it out. Furthermore, if there are other people around, it is also possible to select a mode of use in which the weight measurement result is not displayed on the display 5 and is displayed or printed later.

Effects of the Invention Since the present invention is constructed as described above, by inserting a personally owned memory card into the slot, it is possible to record the weight δl constant data as necessary, and furthermore, it is possible to record data on weight δl as necessary. An internal memory is provided to store the data loaded from the memory card and the data loaded from the memory card as time series data, and by connecting this internal memory to the display, the history of weight changes from the past can be confirmed from the display. It has the following effects:
