Next, the operation of the above embodiment will be explained.

First, the length measuring operation of the electronic tape measure 1 will be explained. When the tape 7 is pulled out from the case 6, the through holes 15 formed in the tape 7 sequentially pass between the light emitter 13 and the light receiver 14. Therefore, when the transparent hole 15 passes through the lower part of the light receiving element provided in the light projector 13, the light receiver 14 is connected to the light projector 13.
It receives light from and outputs a light reception signal. At other times, since the light from the light projector 13 is blocked by the tape 7, no light reception signal is obtained from the light receiver 14. The light reception signal output from the light receiver 14 is given to a waveform shaping circuit 16 and waveform shaped into a pulse signal. The output of this waveform shaping circuit 16 is given to an up-down counter 17 and counted. At this time, since the tape 7 is being pulled out, the direction detector 18 is in the up-down counter 1.
7 is restricted to up count mode. Therefore, the count value of the up-down counter 17 is sequentially incremented by the pulse signal from the waveform shaping circuit 16. The count value of the up-down counter 17 is converted into display data by a decoder 19 and then provided to the measurement length display 8. Therefore,
The length of the tape 7 to be pulled out is numerically displayed on the measurement length display 8.

On the other hand, when the tape 7 is moved in the direction in which it is stored in the case 6, the completely opposite operation to that described above is performed.
The direction detector 18 regulates the mode of the up-down counter 17 to a down-count mode. Therefore, the count value of the up-down counter 17 is sequentially subtracted by the pulse signal from the waveform shaping circuit 16. In this way, the measured length display 8 always displays the current drawn-out length of the tape 7.

Now, when it is confirmed that the drawn-out length of the tape 7 matches the length of the object to be measured, the measurer presses the memory switch 9. Therefore, a storage command is output from the memory switch 9, and the read/write control circuit 21 regulates the memory 20 to write mode.
Therefore, the memory 20 stores the count value output from the up-down counter 17 at that time. Further, pressing the memory switch 9 increments the count value of the counter inside the read/write control circuit 21,
“1” is displayed on the number display 10.

Thereafter, operations similar to the series of operations described above are repeated, and necessary length data is sequentially stored in the memory 20. At this time, the display contents of the number display 10 are updated each time the memory switch 9 is pressed, and the number of times the measurement has already been completed is displayed. Note that the memory 20 stores the measured length data in predetermined areas according to the order.

As described above, when the length measurement is completed at the required length measurement site, such as a construction site, a long body work site, or a manufacturing site, the operator takes the electronic tape measure 1 home and connects it via the connection cord 2. and connect it to the personal computer 3. Thereafter, the automatic length measurement processing device including the personal computer 3 performs desired calculation and display processing.

〔Effect of the invention〕

As described above, according to the present invention, the work of recording or memorizing the length measured with a tape measure, the totaling of the recorded or memorized measurement values, and further,
Since all the work of organizing and inputting data into a computer can be automated, the labor required for this type of work can be greatly reduced, recording errors can be eliminated, and work can be shortened and personnel costs can be reduced.

In addition, the number of measurements that have already been completed is displayed on the number display based on the number of commands from the storage command means, so when performing measurements in a predetermined order, you can smoothly check the number of measurements at a glance. can be measured.
