2. Description of the Related Art As a system suitable for personal identification and the like in a security system, the applicant of the present invention writes a brush when writing with a writing tool having a vibrator on its core. We are developing a handwriting discrimination system that discriminates handwriting based on the peculiarity of core vibration change.
No. 0-42936, Japanese Patent Application No. 2000-59526, and Japanese Patent Application No. 2001-145957 were filed.
Here, this writing discrimination system will be described with reference to the drawings. FIG. 7 is a diagram showing an example of the internal structure of a writing instrument for a writing discrimination system, and FIG. 8 is a block diagram showing an example of a system for controlling the vibration of the writing core of the writing instrument.

FIG. 7 shows an example in which the writing instrument 70 is configured as a ballpoint pen. Stick-shaped brush core 34 (that is, ink shaft)
Is fixed to the outer cylinder 38 via an annular support fixture 36. One or a plurality (one in FIG. 7) of flat surface portions 34p forming a pair are formed on the outer peripheral surface of the brush core 34 at positions facing each other with the central axis C of the brush core 34 interposed therebetween. 34p, the piezoelectric vibrators 40 (40a, 40a,
40b) is attached and fixed by, for example, an adhesive. This piezoelectric vibrator 40 is incorporated in the self-excited oscillation circuit 42, and vibrates the brush core 34 so as to expand and contract in the longitudinal direction, for example.

As shown in FIG. 8, the self-excited oscillation circuit 42 includes an amplifier circuit 44 and a pair of piezoelectric vibrators 40 (40a, 40a).
b) and the filter circuit 46 are connected in series in this order. Of these, the filter circuit 46 has a function of suppressing the influence of unnecessary vibration (spurious) of the piezoelectric vibrator 40. The center frequency thereof is substantially equal to the center frequency of the piezoelectric vibrator 40. The positive electrode 48a of the piezoelectric vibrator 40 is connected to the input terminal of the filter circuit 46, and the negative electrode 48b of the piezoelectric vibrator 40 is connected to the output terminal of the amplifier circuit 44.

From the research conducted by the applicants so far, when writing is performed with the writing instrument 70 in a state where the writing instrument 34 is vibrated, a change in the vibration of the writing instrument 34 during writing (for example, the frequency It has been found that the pattern of (change of) has a characteristic peculiar to the writer. It is considered that this is because the contact state (for example, pressing force, contact angle, etc.) between the writing core 34 and the writing medium (not shown) during writing and the change (for example, writing speed, etc.) differ depending on the writer. Therefore, it is possible to confirm the person by writing by detecting the vibration change data of the brush core 34 during vibration and comparing this with the registered data specific to the writer registered in advance. Note that the frequency of the brush core 34 changes with time (vibration change data)
Can be detected as a signal of the self-excited oscillation circuit 42, and is detected as, for example, data indicating a change over time in the difference in frequency with respect to the center frequency.

[0006] For example, when a person performs an action that is permitted only to a specific person, the writing discrimination system is
The vibration change data at the time of writing by the person is acquired, the acquired vibration change data is compared with the vibration change data registered in advance, and if they match, the person (that is, the writer) permits the action. It is determined that the person has been. There are various actions such as credit card payment and entry / exit at a predetermined gate, as the act of setting permission / prohibition based on the writing determination process. If the actions permitted by different people are different, it is necessary to make detailed permission / prohibition settings for each person.

[0007] Such an act that requires identification is
Both types and numbers are expected to increase in the future. In the handwriting discrimination system, even when the permission / prohibition based on the handwriting discrimination processing is set for various types and many actions, it is necessary to reliably specify for which action the handwriting discrimination is set. I have to. Moreover, the identification of the act should be made easier and faster.

As a processing result, the control unit 2 causes the writer to transmit a signal indicating that the writer is permitted to perform the action, and when the condition is not satisfied, a signal indicating not to be permitted is transmitted. The signal indicating the processing state of the control unit 58 is also appropriately transmitted from the communication unit 62.

The control unit 58 has a record data storage area 60e.
The actual data including at least the action ID and the physical quantity change data detected corresponding to the action ID or the writing determination result based on the physical quantity change data is stored. It can be said that the result data is data that can specify the writer who has made the writing for the writing determination set for the action. The performance data may further include other data such as data that specifies writing (for example, writing time, writing determination time, etc.), identification data (personal ID) of the writer, and the like. This performance data makes it possible to later identify the person who wrote in response to the act, so in case of an accident related to the act or work, etc., take responsibility for it. It will be possible to clarify more.

A treatment plan / results table 112 as shown as an example in FIG. 6 is stored in a storage unit (not shown) of the medical management server 102, and from a predetermined printer 110 connected to the system 100 through a predetermined procedure. Can be output as In the treatment plan, for example, a treatment unit is set for each treatment act or for each predetermined timing, and the treatment plan / actual result table 112 indicates that each treatment unit (in the example in FIG. The content of treatment ("contents of treatment"), a treatment unit identifier ("identification code") for identifying a treatment unit, and a writing column ("sign") for writing determination are described. The treatment plan / actual result table 112 can be used, for example, for treatment management for inpatients.

The medical management server 102 incorporates or is connected with the writing discrimination system 10. In the medical management server 102, in various situations,
Processing based on the writing discrimination result by the writing discrimination system 10 and processing using the information acquired or generated in the writing discrimination system 10 are performed. Hereafter, 1) outpatient consultation in hospital, 2) inpatient treatment,
3) A specific example is shown for the discrimination of writing and the authentication in each case of the delivery of the medicine.

1) Examination of outpatient: On the examination card or the chart of the patient presented to the doctor at the time of examination, a medical treatment department identifier (for example, a bar) indicating a medical treatment department code assigned to a medical treatment department (internal medicine, surgery, etc.) is shown. Code) and a medical examination identifier (for example, a bar code) indicating a medical examination code assigned to the medical examination are printed. Each patient is given a unique patient card, and a patient identifier (for example, a bar code) showing a patient code is printed on the patient card. Further, the doctor has a badge on which a doctor identifier (for example, a barcode) showing a doctor code is printed. When examining a patient, the doctor uses the identifier reading mechanism 22 of the writing instrument 12 to determine the department identifier, the examination identifier,
The reading operation of the patient identifier and the doctor identifier is performed.
An upstream signal indicating the reading result (identifier data) of these identifiers is transmitted from the writing instrument 12 to the central processing unit 14,
In the central processing unit 14, the medical treatment subject, the medical examination (medical examination code), the doctor, and the patient for the action (the medical examination in this case) for which the writing discrimination is set are specified. The doctor performs a writing operation for writing determination with the writing tool 12 at any stage of the examination (start, midway, or after the end). As a result, the physical quantity change data detected during writing is transmitted from the writing tool 12 to the central processing unit 14, where the writing determination is performed.

The handwriting discrimination result obtained by the handwriting discriminating system 10 is, for example, in the medical management server 102, discriminating whether or not the doctor can carry out the medical examination, discriminating whether or not the doctor can prepare a treatment plan, or medication by the doctor. It is used for determining whether or not an instruction can be made, and processing based on the determination. For example, the writing discrimination system 1

The code of the writer authorized by the code; for example, a doctor code or a nurse code) is stored in association with the actual data so that if an accident related to the activity occurs later, the activity will be performed. It becomes possible to easily identify the performer of (or the person responsible for performing).

<Delivery of medicines> When a medicine is to be delivered from the storage locked by an electronic lock, the delivery operator must write the writing implement 1
The identifier reading mechanism 22 of No. 2 is used to indicate the delivery applicant identifier indicating the code of the delivery applicant (for example, doctor code, pharmacist code) and the code of the delivery agent (drug code) printed in advance on the delivery application form. Read the drug identifier. An upstream signal indicating the reading result (identifier data) of these identifiers is transmitted from the writing instrument 12 to the central processing unit 14, and the central processing unit 14 desires to issue for an action for which writing determination is set (in this case, delivery of medicine). Person and drug are specified. After that, the person who wants to leave the warehouse performs a writing operation for determining the writing with the writing tool 12. The physical quantity change data detected during writing is transmitted from the writing tool 12 to the central processing unit 14, where the writing determination is performed. As a result of the writing determination in the writing determination system 10, when the writing by the person who wants to leave the storage is recognized as the writing of the person who is permitted to output the medicine, the medical management server 102 unlocks the electronic lock, while When it is not recognized as the writing of the person authorized to issue the medicine, the medical management server 102 outputs an alarm by voice or display from an output unit (not shown) provided in the field terminal 106 and the like. Do not open the electronic lock of.

The present invention is not limited to the above embodiment. For example, as the physical quantity change data used for writing determination, for example, the detection data of the inclination change of the writing core as described in Japanese Patent Application No. 2000-59526 may be used, or the writing pressure applied to the writing core may be used. The detection data of the distortion change of the writing core or other components based on the above may be used.

A physical quantity change detecting mechanism can be used as the identifier reading mechanism. For example, the bar portion of the barcode is set so that the hardness of the barcode (bar portion) as an identifier formed on a medium (for example, paper) becomes different from the hardness of the medium (for example, becomes hard). For example, it is formed by resin printing. Using the writing instrument shown in the above embodiment, when the bar code is scanned while the vibrating pen core (the tip of the pen) is pressed against this bar code and the medium, when the pen core is in contact with the bar and when the bar is not the bar. The vibration (for example, vibration frequency) of the writing core changes when it is in contact with the portion (that is, the medium). The bar code can be read by detecting this change with the vibration change detection mechanism.

Further, the identifier can be a magnetic bar code, and the identifier reading mechanism can be constructed as a mechanism capable of reading the magnetic bar code. In this case, the magnetic barcode can be formed by printing magnetic ink on a medium (for example, paper) or by magnetizing a magnetic stripe on the magnetic layer. The identifier reading mechanism is
It can be configured as a mechanism having a magnetic head on a part of the writing instrument (for example, an end portion on the side opposite to the side where the writing core projects or another side surface portion).

Further, in the above second embodiment, the case where the writing discrimination system according to the present invention is introduced into medical management is described, but it is not limited to medical care, and is applicable to management of actions, works or processes in various industries. Can be introduced.
