It is common to fill in the data itself and then look at it and input it to a data processing device with a data input device such as a keyboard for tabulation and statistical processing. A mark sheet method and a method of using a coordinate input device can be considered as a method of automatically performing this, but the system is large-scale, and it is not particularly priced for individual users to purchase. As a solution to this problem, a device for inputting a symbol has been realized by detecting pen-up and pen-down of a writing instrument and detecting a time difference between them. This is because the pen is slidably attached to the holder, and when you put the pen on the answer sheet etc. to write the symbol, the pen slides and closes the mechanical switch, and when you finish writing and raise the pen, the pen slides. To go back and open the mechanical switch. A simple symbol recognition is performed by inputting and determining the pen up / down time.

め、書き味の低下を招いていた。The symbol input device currently realized uses a mechanical switch to detect pen-up and pen-down, requires a dedicated pen and is expensive, and other pencils for ballpoint pens. In order to use a plurality of writing instruments such as a felt-tip pen, it is necessary to individually design them, which leads to an increase in product variety development and an increase in price. Also, the life of the mechanical switch is relatively short,
To solve this, it is conceivable to use a mechanism such as a photo switch, but it is expensive, and the stroke until the switch works during pen down is large, that is,
Since there is an operation in which the pen tip sinks with the switch operation, the writing quality is deteriorated.

ら、図３の信号処理回路１０に導かれる。FIG. 1 shows a writing data input device according to the present invention. The writing instrument 1 is for inputting symbols such as "○" and "x" on the answer sheet, and a generally-used pen, ballpoint pen, felt-tip pen, pencil, red pencil or the like can be used. In the pen cap portion 3, the fitting portion with the writing instrument 1 is processed by taper or the like so that these various writing instruments can be used. The pen cap portion 3 has a vibration detecting portion 4 which is a feature of the present invention inside and a switch 5 used for mode switching and the like. When switch 5 is pressed, the input state is entered. These signals are guided from the connection cable 6 to the signal processing circuit 10 in FIG.

号に変換する。FIG. 2 shows writing instruments such as "○", "x", "△",
It is the vibration data which is the output signal of the vibration detection unit 4 when “” is written. The vibrations when the tip 2 of the writing instrument 1 moves on the paper surface appear as these waveforms. These are in a non-vibrating state when the writing instrument 1 is stationary, so that a clear feature appears particularly when "Δ" is written. In this case, it is impossible to distinguish "Δ" by the conventional method of detecting only pen up and down. Because “△” is written with pen down, it cannot be distinguished from “○”. Each waveform of FIG. 2 is the signal processing circuit 1 of FIG.
The signal is guided to 0, amplified by the amplifier circuit 7, and converted by the waveform shaping / processing circuit 8 into a signal having a pulse width that can be easily seen by the data processing device 11.

わせることも出来る。The interface circuit 9 is responsible for transmitting and receiving these signals. In the example of FIG. 3, the data processing device 11 receives the symbol determination from the signal detected by the vibration detection unit 4, but the signal processing circuit 10 is provided with a one-chip microcomputer or the like. It is also possible to make the symbol judgment internally.

能となる。The data processing device 11 has a pattern of each symbol, and recognizes the symbol written by the writing instrument 1 from the input pulse. As shown in FIG. 2, the vibration over a certain time t1 is determined to be “◯”, and the vibration of the relatively short t2, the subsequent vibration of the relatively long t3, and the vibration of the subsequent relatively short t4 are determined. The pattern is determined as "x". The relatively short vibrations of t5, t7, and t9 and the relatively short non-vibration patterns of t6 and t8 between them are “Δ”.
To determine. Further, one vibration pattern of t10 which is relatively short is recognized as "re". By having various patterns in the data processing device, not only the relatively simple symbols such as “◯” and “x” but also numbers and more complicated characters can be identified.

を与え、振動板１８を動かし、振動を検出する。FIG. 4 shows the inside of the pen cap portion 3. As the vibration detecting portion 4, an elastic member 13 is attached to the voice detecting side (opening portion) of the microphone unit 12, and the opening portion is closed to close the outside. , Shuts out noise and improves sensitivity to vibration detection. The weight 14 is attached to the elastic member 13, and when the pen cap portion 3 and the microphone unit 12 vibrate due to the vibration from the writing instrument 1, the weight 14 is stopped by its own inertia so that the elastic member 13 is relatively attached to the microphone unit 12. It acts to give a sound pressure through. Even if the microphone unit 12 itself vibrates, if the diaphragm and the surrounding air also vibrate, the sound pressure is not detected. Normally, the microphone works effectively because the microphone is fixed and there is vibration in the surroundings, and sound pressure is transmitted, so that voice and vibration are detected. 5 and 6 show a cross section of the vibration detecting unit 4 of FIG. The elastic member 13 is deformed by the vibration from the writing instrument 1, and the weight 14 and the microphone unit 12 are relatively moved, whereby a part (R portion) of the deformed elastic member 13 is moved to the microphone unit 1.
A pressure change is applied to the air chamber 17 in such a manner as to protrude into the opening of No. 2, and the vibration plate 18 is moved to detect the vibration.

When it is used, the pressure change applied to the opening of the microphone unit 12 becomes large for the same vibration, and the sensitivity can be increased. The displacement of the elastic member increases with respect to the same force, and the change in the internal atmospheric pressure with respect to the displacement increases, so that the sound pressure applied to the microphone unit 12 increases. 7 is a sectional view showing an example in which a tube-shaped member 13a made of rubber or the like is used as the elastic member 13, and FIG. 8 is an example in which a container-shaped member 13b whose weight 14 side is closed is used as the elastic member 13. The sectional view shown is shown.

に設けることができる。FIG. 9 shows an example in which the writing instrument 1 is held so as to penetrate the grip portion 19, and the vibration detecting portion 4 is built in the grip portion 19. In the embodiment of FIG. 1, if the writing instrument 1 is long, the entire writing tool may become long and difficult to write, but this example solves this problem. Further, the switch 5 can be provided at a position where it can be easily pushed.

う。Although an example in which the vibration detecting unit is attached to the writing instrument side has been shown so far, conversely, the vibration at the time of writing the symbol is detected by the vibration detecting sheet 15 laid under the medium on which the symbol is written. An example is shown in FIG. Ball pen 1 without detection unit
The vibration at the time of entry is detected by the vibration detection sheet 15 equipped with the vibration detection unit 16. FIG. 11 shows a sectional view. The signal detected by the vibration detecting sheet 15 is discriminated by the signal processing circuit 10 and the data processing device shown in FIG.

In addition, the problem of poor writing quality and switch life, which have been problems with conventional switches that involve mechanical displacement due to pen tip pressure, can be solved by using a vibration detector.
