The operation data of a plurality of managed persons is displayed or recorded separately by transmitting a symbol for identifying the individual of the managed person along with the operation data.

  An example of the motion measurement device used in the embodiment of the present invention is shown in FIGS. The motion measurement device shown in FIGS. 2 and 3 was developed by one of the inventors and proposed in Japanese Patent Application No. 2003-187383. For example, the posture change of the measurement object such as each part of the body, that is, the X axis, the Y axis, and the Z axis It is a device that detects a change in capacitance between electrodes due to a change in tilt on an axis as an electric signal as a parameter. For example, if this device is attached to an arm (arm) of a robot, it is possible to detect an angular change in the circumferential direction of 360 ° of the arm.

  In FIG. 2, reference numeral 11 denotes an electrode holder made of an electrically insulating material such as plastic, acrylic or glass. A flat part is formed on the upper surface of the electrode holder 11, and as shown in FIGS. 2 and 3, the bush 15-1 for closely fitting the counter electrode 13 and the outer peripheral electrode 14 are closely fitted. For this purpose, a bush 15-1 insertion hole 15 is formed, and the bush 15-1 is closely inserted into the bush insertion hole 15. The bush 15-1 is made of a flexible electrically insulating material such as silicon rubber. 16 is a counter electrode mounting hole, and 17 is an outer peripheral electrode mounting hole.

  The counter electrode 13 and the outer peripheral electrode 14 are made of a chemically stable (low ionization tendency) conductive material, for example, 18K gold (Au), and in this embodiment, are 0.6 mm rods. As shown in FIG. 2, the counter electrode 13 is closely fitted in the ceiling of the container 12 and the counter electrode fitting hole 16 formed in the upper surface of the electrode holding body 11 fitted to the container 12 and in the center of the plane. . In the state shown in FIG. 2, when the lower counter electrode 13 is immersed in the liquid dielectric B and the container 12 is turned upside down, the counter electrode 13 disposed on the ceiling portion of the container 12 is the liquid dielectric. Soaked in B. Thus, any one of the upper counter electrode 13 and the lower counter electrode 13 has capacitance between the outer peripheral electrode 14 via the liquid dielectric B, and the X axis direction and the Y axis of the container 12 The capacitance changes from the change in the immersion length of the outer peripheral electrode 14 in the liquid dielectric B in response to the change in the inclination angle in any of the directions or in the combined direction, and this can be detected as an electric signal.

  As shown in FIGS. 2 and 3, the outer peripheral electrode 4 is a line segment passing through the plane center point of the upper portion of the electrode holder 11 that fits the ceiling of the container 12 and the inner peripheral surface of the electrode holder 11 of the electrode holder 11. A line segment passing through the plane center point of the upper stage of the electrode holder 11 and perpendicular to the line segment, and an axis (center point) of the container 12 passing through the inner wall surface of the container 12 at a predetermined interval, and its axis Are arranged at intersections with a circle sharing the same, and each forms a pair of outer peripheral electrodes 14 in the X-axis direction and a pair of outer peripheral electrodes 14 in the Y-axis direction. The outer peripheral electrode 14 extends from the bottom surface and the ceiling of the container 12 and is divided in the axial direction thereof.

  As described above, a material with a low ionization tendency, such as 18K gold (Au), is suitable for the counter electrode 13 and the outer peripheral electrode 14, while it is preferable that the impedance between the electrodes be lower. If the impedance between the electrodes is high, various noises will be picked up and cause measurement errors.On the other hand, if the impedance is too low, not only will the power consumption increase, but also the loss of function due to electrode plating, It is determined in consideration of these.

  The container 12 has a cylindrical shape with a ceiling portion closed, and the lower opening portion is closely fitted with the outer peripheral surface of the upper step portion of the electrode holder 11 as shown in FIG. The container 12 is made of an electrically insulating material. In this embodiment, the container 12 is made of acrylic, polyester, polyamide synthetic resin, or the like. As shown in FIG. 2, the liquid dielectric B is enclosed in the internal space of the container 12 at a volume ratio sufficient to form an inclined surface between the free surface and the container 12. In this embodiment, the liquid dielectric B having a volume of 50% of the internal space of the container 12 is enclosed. A is a gas body part, in this embodiment air. The shape of the internal space of the container 12 is a cylindrical shape in this embodiment, but it can of course be a spherical shape.

  As the liquid dielectric B, for example, ethylene glycol, ethylene glycol monomethyl ether, γ-butyrolactone, N-methylformamide or the like is used as a solvent, and adipic acid, maleic acid, benzoic acid, phthalic acid, salicylic acid, basic solute is used as a solute. For example, a solution in which ammonia, aqueous ammonia, triethylamine, tetramethylammonium hydroxide, or the like is dissolved can be used.

  The differential amplifier circuit shown in FIG. 4 can be used as an example of the signal detection means of this motion measurement device. The circuit shown in FIG. 4 works so that the potentials at the n and p points in the circuit are equal.

Since the current does not flow into the input impedance operational amplifier, the currents I ₁ and I ₂ are

Given in. Substituting and organizing, the output voltage V _o is

Can be obtained.

  Further, another example of the motion measuring device used in the embodiment of the present invention, that is, a device for measuring the displacement of each part of the body is shown in FIGS. The device shown in FIGS. 5 and 6 is proposed by one of the inventors in Japanese Patent Application No. 2003-415194. For example, the amount of displacement of a measurement target such as each part of the body is regarded as the extension amount of the coil spring. This is a device for detecting a counter electromotive force corresponding to the amount of expansion and contraction of the spring.

  In FIG. 5, reference numeral 21 denotes one npn transistor, and an input terminal 25 is connected to the base B. An output terminal is connected to the collector C, and the emitter E is grounded via a metal coil spring 23 and a resistor 24 connected in series. The other npn transistor 22 has the same characteristics as the npn transistor 21 and amplifies a signal input from the input terminal 25 by both. In FIG. 5, 27 and 28 are resistors. V is a power supply voltage.

  In this embodiment, the metal coil spring 23 is preferably one obtained by winding a metal material having excellent elasticity and high conductivity, such as phosphor bronze wire. The metal coil spring 23 is also preferably covered with an insulator such as enamel or vinyl. This prevents a short circuit between metals that occurs when the metal coil spring 23 repeats expansion and contraction, and can reduce noise when measuring the displacement of the object. Further, a hollow wire (air core wire) can be used as the wire of the metal coil spring 23.

  Further, by inserting a magnetic core inside the metal coil spring 23 in the radial direction, the back electromotive force generated in the metal coil spring 23 corresponding to the expansion / contraction amount of the metal coil spring 23 is strengthened, and the displacement is reduced. Measurement accuracy can be improved. The magnetic core is preferably flexible so that it can be bent in the same manner as the metal coil spring 23. As the magnetic core material having flexibility, a metal, liquid, or gas material can be used. When using a magnetic core, a film that encloses the gas (gas) is required. By making the magnetic core flexible, the displacement is not limited to a linear one, and even an arcuate displacement can be detected as an electrical signal. Similarly to the metal coil spring 23, the magnetic core material is preferably covered with an insulator. This prevents a short circuit between metals that occurs when the metal coil spring 23 repeats expansion and contraction, and can reduce noise when measuring the displacement of the object.

  Next, the operation of the electrical signal generating device corresponding to the displacement shown in FIG. 5 will be described. When a signal is input from the input terminal, a current equal to the sum of the emitter current of the npn transistor 21 and the emitter current of the npn transistor 22 flows through the metal coil spring 23 corresponding to this signal. The magnitude of the current flowing through the metal coil spring 23 is limited (set) by the resistance value of the resistor 24. However, the resistor 24 is not necessary when each transistor is saturated.

  Here, when the signal from the input terminal decreases, the emitter current of the npn transistor 21 decreases. Thus, the current flowing through the metal coil spring 23 is also reduced. However, in the metal coil spring 23, when the current flowing through the metal coil spring 23 changes, a counter electromotive force that cancels the change is generated. Since the direction in which the emitter current of the current npn transistor 21 flowing through the metal coil spring 23 decreases is the direction of arrow A in FIG. 5, the metal coil spring 23 generates a counter electromotive force in the direction of arrow B. Due to this counter electromotive force, the metal coil spring 23 tries to keep the current flowing therethrough constant, so that the emitter current of the npn transistor 22 increases by the decrease of the emitter current of the npn transistor 21.

  Thus, since the emitter current of the npn transistor 21 and the emitter current of the npn transistor 22 flow complementarily, the signal input from the input terminal 25 is amplified by the npn transistor 21 and the npn transistor 22, The difference (differential component) between these signals is output to the output terminal 26.

  Here, when the metal coil spring 23 expands and contracts, the counter electromotive force generated by the metal coil spring 23 changes corresponding to the amount of expansion and contraction. That is, when the metal coil spring 23 is contracted, a counter electromotive force is generated as a coil, but when the metal coil spring 23 is extended, the counter electromotive force is reduced.

  Thus, when the application of the positive voltage to the input terminal 25 is stopped when the metal coil spring 23 is in the contracted state, the npn transistor 21 is opened. Therefore, the emitter current that has flowed to the metal coil spring 23 through the npn transistor 21 does not flow. Since the metal coil spring 23 has a function as a coil, when the current flowing through the metal coil spring 23 changes, a counter electromotive force that cancels the change is generated. The direction in which the emitter current of the npn transistor 21 flowing through the metal coil spring 23 decreases is the direction of arrow A in FIG. 5, so that the metal coil spring 23 generates a counter electromotive force in the direction of arrow B. Due to this counter electromotive force, the metal coil spring 23 tries to keep the current flowing therethrough constant, so that a current corresponding to the emitter current of the npn transistor 21 that has been flowing through the npn transistor 22 flows. That is, the voltage at the output terminal 26 decreases corresponding to the current from the npn transistor 22 that flows to compensate for the current that flows from the npn transistor 21.

  On the other hand, when the metal coil spring 23 extends, the counter electromotive force generated in the metal coil spring 23 decreases. Thus, by measuring the magnitude of the electromotive force corresponding to the expansion / contraction amount of the metal coil spring 23, the expansion / contraction amount of the metal coil spring 23 itself can be detected as an electric signal.

  The embodiment shown in FIG. 5 can be similarly implemented by a circuit using the pnp transistor shown in FIG. In FIG. 6, 31 and 32 are pnp transistors, 33 is a metal coil spring, 34 is a resistor, 35 is an input terminal, 36 is an output terminal, 37 and 38 are resistors, and V is a power supply voltage.

  As another example of a device that measures the amount of displacement of a measurement target such as each part of the body, the devices shown in FIGS. 7A, 7B, and 7C and FIGS. 8 and 9 can be used. 7 (a), 7 (b), FIG. 8 and FIG. 9, the device shown in Japanese Patent Application No. 2004-045539 proposed by one of the inventors as the amount of displacement of the measurement object is the amount of expansion and contraction of the coil spring. It is a device that detects the change in capacitance corresponding to.

  FIGS. 7A, 7B, and 7C show other examples of devices that measure the amount of displacement of an object. 7 (a), (b), and (c), 201 is a relatively large-diameter conductive coil spring, 202 is a relatively small-diameter coil spring, As shown in FIG. 7B, the wire forming the conductive coil spring is coated with enamel or the like to form a coil spring. Is inserted so as to be relatively displaceable in the axial direction.

  Here, as shown in FIG. 7 (c), when the conductive coil spring 201 having a relatively large diameter extends and one end thereof is displaced in the axial direction of the conductive coil spring, the conductive coil spring having a relatively small diameter. The surface area of the inner diameter portion of the conductive coil spring 201 having a relatively large diameter facing the outer diameter of 202 changes. Due to this, the capacitance between the conductive coil spring 201 and the conductive coil spring 202 changes. That is, the capacitance C between the two changes corresponding to the amount of expansion or contraction of one of the conductive coil spring 201 and the conductive coil spring 202. The capacitance C between the conductive coil spring 201 and the conductive coil spring 202 is

  Given in. Here, the distance (interelectrode distance) t between the inner diameter portion of the conductive coil spring 201 and the outer diameter portion of the conductive coil spring 202 is constant. In addition, the change due to the air concentration of the dielectric constant of the dielectric can be corrected, and thus is substantially constant. Thus, only the change in the interelectrode facing area S due to expansion or contraction of either the conductive coil spring 201 or the conductive coil spring 202 becomes a variable (parameter) of the capacitance C between the two conductive coil springs. . Therefore, the expansion / contraction amount, that is, the displacement of either the inner diameter portion of the conductive coil spring 201 or the conductive coil spring 202 can be measured.

  The electrical signal generating device corresponding to the displacement according to this embodiment is composed of a conductive coil spring, for example, a pair of large and small diameter conductive coil springs made of phosphor bronze, so that the target displacement is linear. It is possible to measure not only anything but also arcuate (curved) displacement.

  The measurement of the displacement of the object in this embodiment can be performed by simply detecting the change in the capacitance C by the circuit shown in FIG. Further, the present invention can also be implemented by a CR oscillation circuit (Wien bridge oscillation circuit) shown in FIG. The circuit shown in FIG. 9 is a circuit that applies a voltage to Input and takes out a change in electrostatic capacitance C caused by expansion / contraction (displacement) of one of the conductive coil springs in the device shown in FIG. 7 as a frequency change. . Since the circuit shown in FIG. 9 is an oscillation circuit, it is detected as a frequency that changes due to expansion and contraction of the conductive coil spring in the device shown in FIG.

As shown in FIG. 10, the wireless communication device attached to the person to be managed shown in FIG. 1 is a business card size, has a program and a memory, and generates a signal amplification unit, an A / D conversion unit, and a digital signal.

Patient behavior management system in hospitals In recent years, medical institutions such as hospitals have a serious shortage of nursing staff due to advancement of medical contents and cost reduction. On the other hand, if you keep an eye on the patient, the risk of accidents increases and serious accidents can be a big risk in hospital management. Therefore, the behavior management system using the operation device according to this embodiment is used by a small number of nursing staff, such as a patient who is efficiently a patient, who is mentally problematic, a patient whose problem behavior is frequent, a patient whose condition is suddenly changed, and the like. It is a system that manages behavior and immediately notifies nursing staff if there is a problem.

The following equipment is installed in this system.
(A) A master station (wireless LAN access point) of a wireless communication apparatus and a management computer connected thereto are installed in a nurse station or the like.
(B) A motion measuring device and a slave unit of a wireless communication device are attached to a target patient. When obtaining position information with an RFID tag, an RFID tag reader is also attached.
(C) When obtaining position information, RFID tags are installed at regular intervals in the site.
(D) If the staff is not always present at the grounding location (nurse station or the like) of the management computer, the nursing staff carries a portable terminal equipped with a wireless communication function.

Process (a) The motion measurement device attached to the patient sends the posture of the patient together with the identification number of the patient to the management computer through the wireless communication device every predetermined time (for example, 1 second). At that time, it is desirable to read the tag installed nearby by the reader of the RFID tag and simultaneously send the patient position information. Also, in the case of trouble on the operation measuring device side (battery exhaustion etc.), the message is sent to the management computer.
(B) The management computer performs the following processing shown in FIG. 12. (1) Based on the identification number, posture data (and position information) for each patient is recorded.
(2) The current motion of the patient is estimated from recent time-series posture data. For example, walking when the whole body is almost upright and the legs are moving, standing up when the whole body is almost upright and the legs are not moving, and lying down when the whole body is almost horizontal.
(3) Display the status of all patients under management on the screen. An example of the screen layout is shown in FIG.
(4) Check for the presence or absence of various types and warn if an abnormality is detected. Possible abnormalities are as follows, for example.
(I) If the robot is stationary in the same posture for a certain period of time, a warning is given because there is a possibility that the patient is unconscious or the patient may have removed the device.
(Ii) When the amount of exercise exceeds a certain level, for example, when the body is moving violently while lying down, a warning is given because there is a risk of sudden changes in the condition.
(Iii) If the correspondence between the operation and the position is abnormal, for example, lying on a place other than the own room is warned because there is a possibility of sudden change in the condition.
(Iv) If an abnormal posture is continued for a certain time or more, there is a possibility of sudden change of the condition or a mistake in mounting the device, so that a warning is given.
(V) It is checked whether the posture data of a plurality of patients is not the same. If there is the same posture data, a warning is given because there is a possibility that a plurality of devices may be worn on the same person (so-called change of clothes).
(Vi) Warn in case of troubles such as running out of battery. In addition, if communication is interrupted, there is a possibility that the device has trouble or the patient has gone out, so a warning is given.
(5) The warning is also transferred to the mobile terminal of the nursing staff.
(C) When the mobile terminal of the nursing staff receives a warning from the management computer, it notifies the owner staff of the abnormality with a display and a sound.

Hospitality employee management system in the restaurant industry Even in the service industry, mainly in customer service, there are limited ways to manage and evaluate employee performance even though the performance of each employee is directly related to sales. For example, even in a foreign-affiliated hamburger chain store, which is said to be the most advanced in management, it depends on maintenance of manuals and visual evaluation by managers called store managers and managers, making it easy to measure individual employee performance. There was no way to evaluate. The employee management system according to this embodiment directly measures the performance of each employee, realizes appropriate management and evaluation, and contributes to prevention of accidents due to employee fatigue and the like.

The following equipment is installed in this system.
(A) A management computer is installed in a store office or the like. The management computer is equipped with a master unit (wireless LAN access point) (online type) or a memory card recording device (batch type) of the wireless communication device by means of data fetching.
(B) The target employee is equipped with a motion measurement device and a wireless communication device slave unit (online type) or a memory card recording device (batch type). When obtaining position information with an RFID tag, an RFID tag reader is also attached.
(C) When obtaining position information, RFID tags are installed at regular intervals in the site.

Processing (a) The motion measurement device attached to the employee sends the employee's posture together with its identification number to the management computer through the wireless communication device (online type) or memory every certain time (for example, 1 second) Record on the card (batch type). At that time, in a business type where employees work mainly on the floor of the audience seats, such as a so-called family restaurant rather than a fast food store where many employees are in the counter, RFID tags are used to read tags installed nearby. It is desirable to send employee location information at the same time. However, in order to protect employee privacy, it is necessary to be able to stop transmission or recording when necessary (for example, about 5 minutes per hour). Further, in the case of a trouble on the operation measurement device side (battery exhaustion or the like), the online system sends the message to the management on-computer.

(B) The management computer of the online system performs the following processing as shown in FIG.
(1) Based on the identification number, posture data (and position information) for each employee is recorded. This data is used for the purpose of detecting the employee's state as time series data, and the same processing as that of a batch type system described later can be performed.
(2) The current movement of the employee is estimated from the latest time series data. For example, walking when the whole body is almost upright and the legs are moving, standing upright when the whole body is almost upright and the legs are not moving. Further, it is determined whether or not the user is moving from the position and the whole body motion, and states such as “in-store patrol” and “standby” are determined.
(3) Display the status of all employees under management on the screen. An example of the screen layout is shown in FIG.
(4) Check for the presence or absence of various abnormalities. Possible abnormalities are as follows, for example.
(I) If the camera is stationary at the same position and posture for a certain period of time or more, a warning is given because there is a possibility of a virtual break or the device being removed.
(Ii) If an excessive amount of movement continues for a certain time or longer, or if the movement is continued for a long time, there is a risk of excessive fatigue, so the administrator warns to arrange for cheering.
(Iii) If the amount of movement is significantly reduced, the posture is abnormal, or the movement speed is reduced, there is a risk of excessive fatigue, so that the administrator warns to arrange for cheering.
(Iv) If an abnormal posture is continued for a certain period of time or more, there is a possibility of a device installation error or the like, and a warning is given.
(V) It is checked whether the posture data of a plurality of patients is not the same. If there is the same posture data, a warning is given because there is a possibility that a plurality of devices may be worn on the same person (so-called change of clothes).
(Vi) Warn in case of troubles such as running out of battery. Also, if communication is interrupted, there is a possibility of equipment trouble, so a warning is given.

(C) The management computer of the batch type system performs the following processing as shown in FIG.
(1) At the time of change or at the end of work, posture data (and position information) for each employee is read from a memory card and recorded together with an identification number.
(2) The behavior of the employee is estimated from all time series posture data. For example, walking when the whole body is almost upright and the legs are moving, standing upright when the whole body is almost upright and the legs are not moving. Further, it is determined whether or not the user has moved from the position and the whole body motion, and states such as “in-store patrol” and “standby” are determined for each time.
(3) Evaluate the employee's performance from all time series data and warn if necessary.
(I) When focusing on a specific performance, such as the depth of bowing or the loudness of a greeting (assuming that a voice input device is attached), the relevant part is extracted from the action sequence, for example, the employee's Evaluate the average depth of bowing.
(Ii) If the excessive amount of movement continues for a certain period of time, or if the movement is continued for a long time, or if the movement amount is significantly reduced, the posture is abnormal, or the movement speed is reduced, Warn managers to improve employee management in the future as excessive fatigue may occur.
(Iii) Check whether or not the posture data of a plurality of employees is the same. If there is the same posture data, a warning is given because there is a possibility that devices for a plurality of people may be worn by the same person (so-called change of clothes). .
(Iv) Matching the overall numerical index, comprehensively judging performance and giving necessary warnings.
(4) All these evaluation data are displayed on the screen together with necessary warnings. An example of an individual layout is shown in FIG.

The behavior management system for outside sales staff In the past, the behavior management of employees who went outside was nothing but a daily report recorded by the person himself / herself. Therefore, it was practically possible to know how much the employee himself was working only through the results of business negotiations. The behavior management system using the operation device of the present invention according to this embodiment can directly measure the performance of the outside sales staff to realize appropriate management and evaluation, and can also reduce the trouble of describing the daily report of the employee himself / herself. . The present invention is applicable not only to sales staff but also to other businesses.

The following equipment is installed in this system.
(A) A management computer will be installed at the sales office. A memory card reader is connected to the management computer.
(B) The target employee is equipped with a motion measurement device and a memory card recording device. In order to obtain position information, a GPS receiver is also attached.
(C) If the employee creates daily reports in electronic form using the data of this system, an appropriate number of computers for creating daily reports will be required.

Processing (a) The motion measurement device attached to the employee records the employee's posture on the memory card every predetermined time (for example, 1 second). At that time, it is desirable to record the position information of the employee at the same time using GPS or the like. However, in order to protect employee privacy, it is necessary to be able to stop transmission or recording when necessary (for example, about 5 minutes per hour).

(B) The management computer of the batch type system performs the following processing as shown in FIG.
(1) At the time of change or at the end of work, posture data (and position information) for each employee is read from a memory card and recorded together with an identification number.
(2) The behavior of the employee is estimated from all time series posture data. For example, walking when the whole body is almost upright and the legs are moving, standing upright when the whole body is almost upright and the legs are not moving. Further, it is determined whether or not the user has moved from the position and the whole body motion, and states such as “moving” and “sitting” are determined every time.
(3) Employees prepare daily reports based on this data. If the behavior estimates are incorrect, correct them.
(4) Evaluate the employee's performance from all time series data and warn if necessary.
(I) If a specific posture (for example, lying down) continues for a certain period of time, the employee is warned to reconfirm the working status.
(Ii) A warning is given if the daily report contents by the employee himself / herself are inconsistent with the position / motion data, or when the correction of the behavior estimation is unnatural.
(Iii) When the excessive amount of movement has continued for a certain period of time or when the movement has been continued for a long time, or when the movement amount is remarkably reduced, the posture is abnormal, or the movement speed is reduced Warns managers to improve employee management in the future as they may have caused excessive fatigue.
(Iv) Check whether or not the posture data of a plurality of employees is the same. If there is the same posture data, a warning is given because there is a possibility that devices for a plurality of people may be worn on the same person (so-called change of clothes). .
(V) Combine the overall numerical indicators, comprehensively judge performance and give necessary warnings.
(5) All these evaluation data are displayed on the screen together with necessary warnings. An example of an individual layout is shown in FIG.

Action estimation method (a) Regardless of posture, if the position data by GPS changes at a constant rate, the time interval is regarded as movement.
(B) If the vehicle is stationary for a certain period of time between movements, the time interval is considered as a transfer, and the movement is integrated with the previous and subsequent time intervals.
(C) If position data obtained by GPS cannot be obtained at a certain time and position data obtained by GPS is obtained again at another place separated by a certain distance or more, the time interval is regarded as movement. However, if it takes significantly longer than the means of transportation in the meantime, a warning is given.
(D) Continue a certain posture (for example, standing upright or sitting) at a certain place (including the case where GPS position data is no longer obtained and GPS position data is obtained again at another place more than a certain distance). If this happens, it is determined that the section is standing or sitting. However, if the time is short, it is integrated with the preceding and following time intervals, and it is determined as standing work, sitting work, etc. at the ratio of the whole posture.
(E) For the location, if the location is registered in advance, the location name (“A comprehensive development” in the display example in the management computer shown in FIG. 19); otherwise, the location is a landmark Indicates the name (“Shibuya Station East Exit” in the display example in the management computer shown in FIG. 19), and if it does not correspond to any of the names, the address is displayed. It is up to the employee himself to fill in what address the address is.
