pcs, "/" mark indicates 1 pcs. Therefore, in order to recognize the shape drawn by the writing instrument 205, it is sufficient to count the number of peaks in the envelope. Therefore, the recognizer 140 as an embodiment of the signal recognition means in the device of the present invention described above recognizes the shape drawn by the writing X2O3 based on counting the number of peaks in the envelope of the performance signal generated on the sensor body 200. There is. That is, Fig. 437 shows the converter 1 shown in Fig. 4 (a).
30 and 91! FIG. 2 is an explanatory diagram of the operation of the detector 140. The electrical signal output from the sensor main body 200, for example corresponding to the rOJ mark, is given to the amplifier circuit 131, and
1 supplies a signal as shown in FIG. The shaping circuit 132 shapes the signal from the amplifier circuit 131 and outputs a pulse signal group Sl having a short pulse width as shown in FIG. That is, this pulse signal group S1 is a signal given from the converter 130 to the +m detector 140.

Then, the pulse signal group S1 given from the converter 130
is the monostable multivibrator 141, 1 of the recognizer 140
42 respectively. Here, the operating time -rl of the monostable multivibrator 141 is set to be longer than the interval between pulse signals #81, so its output is one pulse with a long pulse width as shown in Fig. becomes. On the other hand, since the operating time of the monostable multivibrator 142 is set to be shorter than the mutual interval of the pulse signal group Sl, the monostable multivibrator 143 is operated as shown in FIG.

The number of pulses S3 equal to the number of peaks on the envelope of the electrical signal outputted by 0 is output. The output signals of the monostable multivibrators 141 and 142 are respectively applied to a NAND circuit 143, and as a result, the NAND circuit 143 outputs a recognition signal S4 as shown in FIG. That is, this signal is the output signal of the recognizer 140. Also in the same figure)
) is given to the signal tone generator 107 via the interface 171, and based on this, for example, a speaker is driven, so that the operator can easily hear the completion of one scoring. In addition to the above-described embodiments of the converter 130 and recognizer 140, the same purpose as above can also be achieved by using a configuration as shown in FIG. 4(B). I can do it. That is, the sensor body 200
The output signal of the converter 130 including the amplifier circuit 131 is input to the recognizer 140, and the signal sampled by the sampling circuit 144 and the signal to be generated when drawing a predetermined shape are stored in advance in the memory circuit 145. The discrimination circuit 146 compares and discriminates the sampling signal with the reference signal, and when the sampling signal matches any one of the numbers stored in the storage circuit 145, the discrimination circuit IJ3 corresponds to the reference signal. It may also be possible to output an identification signal to identify the user.

The next operator to score is the data key 111 and function key 12 on the keyboard 110.
When point allocation data such as the number of classes, number of students, number of questions, and points for each dose line are input based on the operation of 0, this point allocation data is written to the RAM 152 via the interface 171 and the central processing unit 160. At this time, when it is possible to input point allocation data, the point allocation lamp 101 is lit. When the input of the scoring data is completed, the operator gives a scoring command to the central processing unit 160 via the interface 171 by operating the scoring key 126 and the input key 121 of the function keys 120. For example, the grading lamp 102 changes from red (indication that manual labor is prohibited) to green (
The operator is informed that it is possible to input scoring data by lighting the ``Manual input possible display''. Then, when the operator operates the start no stop switch of the switch body 200 to start scoring, the converter 130 is activated by the writing instrument used to draw shapes such as "○", "mu", "f/", etc., as described above. convert the target signal into an electrical signal,
to the recognizer 140. The recognizer 140 recognizes the characteristics of the given electrical signal and sends the corresponding rjim signal to the central processing unit 160 via the interface 171.
In addition, the central processing unit 160 writes recognition (No. 8 as scoring data into the RAM] 52. Furthermore, when incorrect scoring data is input, the error switch 221 is operated to erase the pig. In this way,
When the input of all scoring data is completed, the operator performs a predetermined operation on the data key 111 and the function key 120 of the keyboard 110, so that the central processing unit 160, for example, An average value calculation is performed, and the result of the calculation is output and displayed on the display 103 via the interface 171 or on the printer 104 via the interface 172.

As is clear from the above description of the embodiments of the device of the present invention, according to the scoring aggregation analysis device of the present invention, the writing instrument used when drawing “○”, r6J, “/”, etc. during grading The recognition signal obtained by converting the target vibration into an electric signal and performing WL weaving on this is stored as scoring data, and furthermore, using a pre-installed calculation program,
The scoring data can be immediately compiled and analyzed, and the results can be output and displayed, making it possible to significantly reduce the time required to compile and analyze scores for various exams, as well as to produce tabulated and analyzed results with fewer errors. Obtainable. Therefore, the device according to the invention is of great practical value.

It should be noted that a means for converting the mechanical vibration of the writing instrument in the sensor main body 200 into an electrical signal as described in the embodiment (but not limited to this) may be used, for example, by attaching a magnet to the sensor main body 200 in association with the writing instrument. It may be possible to utilize the electromotive force of the induction coil generated based on the change in magnetic flux caused by transmitting the mechanical vibration of the writing instrument to the magnet by arranging the induction coil close to the magnet.

Further, the present asserting device can be used in a printer 10 as described in the embodiment.
4 etc. may be removed and the total and analysis results may be displayed only on the display 103, and by doing so, the apparatus of the present invention can be made extremely compact.
