Description

[Detailed description of the invention]

The present invention relates to a tapping measuring device for measuring finger motor function. The tapping measuring device measures the number of times the subject taps while moving up and down over a predetermined stroke width, and records the degree of impairment of phalangeal function based on this 11°. Conventional tapping devices have light 111. at the upper and lower limits of the stroke 116. A switch is provided, and this λ
The nine fingers turn off the light 111□ switch and the light is interrupted, thereby detecting tapping. Then, a timer is used to count the number of tappings within a predetermined time, and the results are displayed digitally. In this way, the conventional device only measures the number of tapping times when the finger under test moves up and down the stroke width (approximately one tap per day for an average person).Therefore, the movement of the finger under test!
Contacting the speed, upper limit member, and lower limit member: lI,'
rf! IF etc. can be measured easily. The present invention overcomes the shortcomings of the prior art and measures not only the number of tappings, but also the moving speed of the sum of experience, the contact time with the upper limit member and the lower limit member, etc. 1
'! Hita J's objective is to provide a tapping measuring instrument that can be used to measure the tapping temperature. 1]: In order to accomplish the purpose described above, the present invention is based on the conventional 4
Knocking” 11 Determines the time when the finger to be parked touches the upper limit member, lower limit member, etc. and the time during which it moves between them.

It's happening. That is, based on the inputs to the flag terminals F1F2 and F3, it is determined whether the object is in contact with the upper limit layer, the lower limit member, or is moving, and the data is sent to the data switcher OJ'.

A signal from the microcomputer j0 is given to the microcomputer j0 via the data bus j0. The operation of the circuit shown in FIG. 3 will be explained with reference to the μ diagram timing chart. Surin) Ja, ,? 1) through the light receiving element ja,,! The light that enters 'b is blocked by the subject.
When the Schmitt trigger circuit 5oia. Assuming that the output from 301b is L, the output of NAND circuit 30.2 is only active when the test finger is touching the lower limit member or moving upward. Here, -il1 leg R1', H difference is decreased by 1, etc.), for example, the travel time at the time of vertical luck J1 of the third test, I)llt, jin at the time of contact, It is assumed that the number of double-lower movements is counted by the microcomputer J'O Hiroshi. When the subject contacts the upper limit member at time T, the seamit trigger circuit! The outputs of 0/a and 30/b are
Since TJ becomes H, an L signal is manually input to the flag terminal F3. With this, the microcomputer
tol/, &: 1, it is determined that the subject has contacted the upper limit member, and a reset l-(M number SO≠b is issued. Counter J'
o6 and FP"t07 are reset by this reset signal (0)) 1.41 + 11 constant starts. During the period from time T to T4, counter 3t) t
counts clock pulses OL. Here, as mentioned above, the clock pulse OL is /KH2, Pme 1.2
．． By subtracting the force l of the clock pulse CL of t4 milliseconds, the bit output of the counter 06 becomes II.
, this genius is FF,! ;07 clock input ZfiH
The force error f+ is applied to the child, and the count result of the clock pulse OL is stopped i. In this way, compared to ordinary people's tapping times (about 4 times per day), it's a lot easier! 1) Tapping less than 1' will cause nQ measurement.
There are 7. When the subject leaves the upper limit member at time T4, the outputs of the cinema trigger circuits jt01FL and jrO/b both become H, so the flag terminal Fl lFW r F
No. 44 of L is input "(4, l") in any case of B. As a result, the microcomputer 5oti assumes that the subject has left the upper limit member and reads 4411fft L, 4, 4, 4, 4, 44, and 4411fft L, readout A, δ, and rO. The data switch O3 is output from the city 1.
It operates according to No. 7 50≠已, and the count result of counter jO6 is sent to the data bus! It is given to the microcomputer 3'OJ- via the 0. By this, upper 1 to 11ζ・
The god time t, is found. micro computer jo
When the clock reaches the end of the count, it immediately issues a reset signal SO≠b, and the counter jO6 increases the count of the clock pulse OL by ρf;. Note that i・′] Exit 4. issue! The shorter the time at bt for emitting iO hiroa and emitting force reset signal SOg b, the smaller the measurement error. Thereafter, in the same manner, "downward movement time t2 from point r T4 to T, lower limit contact time from time T5 to T6"
When moving upward from the 1st point T6 to T7, [[1] is obtained. When the oil constant period of time t1 + t2 + t3 + t4 is completed, the stroke width between the limiter and the limit member is measured, and the result is sent to the microcomputer 304+ via the data pasta 07. :j I can. In this way - ('
Measuring the stroke width and lower blade movement for 1 hour determines the downward movement speed, upper blade movement speed, (how it was developed)
. As described above, according to the present invention, the time period during which the test finger is in contact with the lower limit member 1 and the lower limit member B [X material, or that/1.
11. Moved the old 1 from +17. Since it can be measured by counting clock pulses with a counter ', it is possible to measure the tapping times p as in the conventional case. In addition to p11 constant, C (moving speed of test finger, tapping pressure f, 7 points) and σ)? It is possible to follow the Tapping 1 Ruler (a).
