The effects of the above configuration will be explained below.

Make sure that the pointer on the operation display board is located above the starting line zone. After that, the piece 11 provided on the side of the recording card is set and inserted through the card insertion hole 5. Recording card B when inserted
At the side surface B, 1, the tips 19, 2 of the moving lever are slid, and the shaft 18 rotates against the coiled spring, and the arm member rotates accordingly and is fixed to the tip of this arm member. The card switch is moved away from the slide piece 24 and moved away from the actuator 22,1.
is released, and the card switch changes from OFF to ON (position indicated by the two-dot chain line in Figure 5).

On the other hand, when the number setting piece 11 provided on the side of the recording card and the date setting piece 11 hits the stopper 14,
The recording card is stopped and the recording card is set on the scale plate. After that, when you step on the scale body and put your weight on it, the scale plate rotates according to your weight using the conventional scale mechanism, and the weight is displayed on the display window. 38 leaves between the main switch and the magnet. Then, the main switch, the reed switch, is magnetized and the main switch is turned on. In this way, the card switch is ON, the main switch is ON,
Then, battery power is applied to the motor, the motor rotates, is decelerated by the gear in the gearbox, and is transmitted to the output shaft 26. When the output shaft begins to rotate, the flexible wire, operation switch lever, cam, and card switch lever that are fixed to the output shaft begin to rotate. Therefore, since the flexible wire 33 is connected to the pointer on the operation display board, as the flexible wire rotates, the pointer 34 begins to rotate from the starting line zone 16,1, and the pointer 34 starts to rotate from the start line zone 16,1, and the pointer 34 starts to rotate from the start line zone 16,1, and the pointer 34 starts to rotate from the start line zone 16,1, and records are recorded by looking at this pointer. When you know that operation has started, stand on the scale body until the pointer makes one revolution on the operation display board. As soon as the operating switch lever 28 leaves the actuator 30, 1 of the operating switch 30, the operating switch 30 changes from OFF to ON. Therefore, if you step off the scale body during measurement (while putting your weight on the scale body), the scale plate will return to its original position, and the main switch 35 will be closed by the shielding plate.
Even if it is OFF, the operation switch 30 as mentioned above.
is already ON, the motor continues to rotate, and the output shaft rotates once to stop the motor, which is a precaution against unforeseen circumstances. In addition, in the case of a person whose weight is close to 100 kg, the scale plate rotates once and the shielding plate attached to the scale plate also rotates once and is located between the main switch 35 and the magnet 37, and the main switch is closed.
It is OFF, but the operation switch is ON as mentioned above.
Because of this, the output shaft continues to rotate.

The cam 29 pushes up the pressing body 31 as the output shaft rotates, and the plate pieces 31 of this pressing body 31
At step 1, the outer periphery of the scale plate is further pushed up, and the needle 8 fixed to the scale plate is pierced into the weight recording surface 9 of the attached recording card to mark the weight value at that time. As the cam rotates, the pressing body descends due to its own weight, and the dial plate becomes parallel and returns to its original position.Meanwhile, the card switch lever 27 rotates once, and the card switch (indicated by the two-dot chain line in FIG. 5) It is turned OFF in conjunction with the actuator 22, 1' at the position). Along with this, operation switch 2
8 is also turned OFF, and the pointer 34 moves 1 on the operation display board.
It rotates, returns to the starting line zone, records the weight on the record card, and then the motor stops. After that,
By getting off the scale body, the scale plate returns to its original position, and the main switch 35 is turned off by the shielding plate. Then, the user pulls out the record card from the record card insertion hole of the scale body and learns the measured weight marked on the record card with the needle hole. At the same time as this recording card is pulled out, the moving lever 19 returns inward around the shaft 18, and the card switch 22 is separated from the card switch lever 27, and the card switch actuator is attached to the slide piece 24 provided on the side of the gear box. The ethers 22,1 come into contact, turn off, and return to the original state.

[Effects of the invention] As described above, after setting the recording card, all you have to do is put your weight on the scale body, and the weight is automatically recorded. There is no need for preparation before measurement as in the past, and the measurement is easy. It's easy and very convenient.
