Abstract

<P>PROBLEM TO BE SOLVED: To provide an information acquisition system which allows a first meeting person to know, without notification from a second meeting person, who is a meeting counterpart, that the counterpart will be late for a meeting time. <P>SOLUTION: Moving condition information of means of transportation the meeting counterpart is using is acquired (S40). On the basis of the moving condition information, it is decided whether a delay is occurring in the means of transportation the counterpart is using or not (S41). When the delay is occurring, an estimated time of arrival at a meeting place is determined on the basis of the delay (S42), and by comparing the estimated time of arrival to a predetermined meeting time, it is decided whether the meeting counterpart will not be in time for the meeting time or not (S43). When decided that the counterpart will not be in time for the meeting time, the meeting time is changed to the estimated time of arrival determined in S42 (S44), and a driver who will pick up the meeting counterpart and the meeting counterpart are notified of the changed meeting time (S45, S46). <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  According to the present invention, a first queuing person meeting with a second queuing person at a predetermined meeting place obtains the estimated arrival time of the second queuing person who is riding on the moving body and heading for the meeting place. The present invention relates to an information acquisition device and a navigation device including the information acquisition device.

  When the first meeting person and the second meeting person meet at a predetermined meeting place, the meeting person may be a car, a train, an airplane, etc. depending on the distance to the meeting place and the position of the meeting place. We will head to the meeting place using a moving object.

  Both meeting persons determine the waiting time in consideration of the moving time by the moving body, and use the moving body to go to the meeting place in time for the waiting time.

  However, the arrival time of the mobile object may be delayed due to various circumstances. For example, the arrival time may be delayed due to the failure of the moving body or the weather. In the case of an automobile, it may be delayed due to traffic jams.

  If the arrival time at the meeting place is likely to be delayed, the meeting person wants to inform the other meeting person that it is likely to be late. Therefore, in the car navigation device described in Patent Document 1, the estimated arrival time is calculated based on the distance of the route to the destination, and if the estimated arrival time is later than the desired time, a message to that effect is given to the user. I am trying to inform you. By receiving the notification, the user can surely recognize that the arrival at the destination is delayed. Therefore, the user can be notified of the delay by the telephone or the like.

Further, in Patent Document 2, the current position of one user who is heading to the meeting place is detected by the position detecting means of the navigation device, and road traffic congestion is taken into consideration from the positional relationship between the current position and the meeting place. The estimated arrival time at the meeting place is calculated. When the estimated arrival time is later than the waiting time, a message indicating that the scheduled arrival time is delayed at a predetermined transmission timing is automatically transmitted to the waiting party.

  When heading to the meeting place with a vehicle equipped with a navigation device, the means described in Patent Document 1 and Patent Document 2 can be used to notify the meeting partner of the arrival delay. However, there are also cases where we are heading to the meeting place by train or airplane. As such a case, for example, it may be possible to wait at a station or airport on the way home from a trip.

  Since the use of mobile phones and the like on the train is restricted, even if you notice a delay in the train, it is difficult to notify the person on the train that you will be late. In addition, the mobile phone must be turned off in the aircraft. For this reason, even if the user notices that the aircraft is delayed, it is difficult for the person on the aircraft to notify the meeting partner that the aircraft is delayed.

  In addition, even if the moving body being used is a vehicle, if the vehicle is a route bus, use of a mobile phone or the like is restricted as in the case of a train. There is a problem similar to that.

  In addition, when the moving body being used is not a vehicle for public transportation such as a private car, it is possible to use a mobile phone or the like while the vehicle is running other than the driver. Since the operation of the mobile phone or the like can be performed only by stopping the mobile phone, it is possible to notify the meeting partner that the user is behind the meeting time by using the technique described in Patent Document 1. Moreover, if the technique of patent document 2 is used, it can notify a meeting partner automatically that it is late for meeting time.

  However, the techniques of Patent Document 1 and Patent Document 2 both notify the other party of the waiting time from the side that is delayed in the waiting time, and the other waiting party is the partner unless there is a notification from the delayed side. There is a problem that (the late side) cannot know that it is late. However, as described above, there are cases where it is difficult to notify that from the delayed side.

  The present invention has been made on the basis of this circumstance, and the purpose of the present invention is that the first queuing person can receive the second notice even if there is no notification from the second queuing person who is the queuing partner. It is an object of the present invention to provide an information acquisition apparatus capable of knowing that a meeting person is late for a meeting time.

  In order to achieve the object, the invention according to claim 1 is such that a second queuing person moving on a moving body toward a predetermined meeting place with the first meeting person arrives at the meeting place. The second queuing person mobile body information for acquiring the movement status information of the mobile body on which the second queuing person is riding, wherein the first queuing person obtains the estimated arrival time to be obtained. Based on the movement status information of the moving object acquired by the acquisition means and the second waiting person moving body information acquisition means, the second waiting person arrival that determines the estimated arrival time for the second waiting person to arrive at the meeting place And an expected time determination means.

  If it does in this way, in the 2nd waiting person arrival prediction time determination means, the arrival expectation time of the 2nd meeting person will be based on the movement situation information of the moving body acquired by the 2nd meeting person moving body information acquisition means. Therefore, even if the second meeting person does not tell the first meeting person his / her expected arrival time, the first meeting person can know the estimated arrival time of the second meeting person. Therefore, even if there is no notification from the second meeting person, the first meeting person can know that the second meeting person is delayed in the meeting time.

  Here, preferably, as described in claim 2, the information acquisition apparatus is configured to acquire a first queuing person movement that acquires movement status information of a moving body used by the first queuing person to go to the meeting place. A first waiting time for determining an estimated arrival time for the first meeting person to arrive at the meeting place based on the movement status information of the moving object obtained by the body information obtaining means and the first meeting person moving object information obtaining means; And a person arrival expected time determination means.

  In this way, the first queuing person can also know his / her expected arrival time, so compare the expected arrival time of the second queuing person with his / her expected arrival time, if necessary. Measures such as changing the waiting time can be made.

  In addition, the information acquisition device according to claim 2 is a device in which the information acquisition device is mounted on a vehicle as described in claim 3, and the mobile object on which the first queuing person is riding is moved. It is preferable to acquire movement status information of the vehicle as the status information. However, as the movement status information of the moving body on which the first queuing person is riding, in addition to or instead of the movement status information of the vehicle, the movement status information of the airplane and the train can be acquired. Good.

  Preferably, as described in claim 4, the information acquisition device according to any one of claims 1 to 3 is the arrival of the second queuing person determined by the second queuing person arrival expected time determining means. Second waiter delay determination means for determining whether or not the second waiter is likely to be delayed from the wait time based on the expected time and a preset wait time, and the second waiter delay determination means In this case, when it is determined that the second meeting person is likely to be late for the meeting time, the time changing means for changing the waiting time to the time when the second meeting person can arrive, and the time changing means Change time notifying means for notifying the first waiter of the waiting time, and the waiting time changed by the time changing means as the second waiting time. In which further comprising a change time sending means for sending the combined user of the receiving device.

  In this way, even if the second queuing person does not notify the first queuing person that he / she is likely to be late, the second queuing person automatically meets based on the estimated arrival time of the second queuing person. Since the time is changed and the changed waiting time is notified to the first meeting person and transmitted to the second meeting person, the second meeting person can be notified even if there is no notification from the second meeting person. The waiting time can be changed according to the expected arrival time of the waiting person.

  Preferably, as described in claim 5, the information acquisition device according to claim 2 or 3 is configured to have an arrival expectation time of the first queuing person determined by the first queuing person arrival expectation time determining means. Based on a preset waiting time, the first waiting person delay judging means for judging whether or not the first waiting person is likely to be late for the waiting time, and the second waiting person arrival expected time determining means. Second queuing person delay judging means for judging whether or not the second queuing person is likely to be late for the waiting time based on the determined expected arrival time of the second queuing person and a preset waiting time. In the first waiter delay determination means and the second waiter delay determination means, the first waiter and the second waiter When it is determined that one of them is likely to be late for the waiting time, a time changing means for changing the waiting time to a time when both meeting people can arrive, and the waiting time changed by the time changing means are set to the first time. Change time notifying means for informing the waiting person and a changing time transmitting means for transmitting the waiting time changed by the time changing means to the receiving device of the second waiting person.

  In this way, the waiting time is changed based on the expected arrival time of the first queuing person and the expected arrival time of the second queuing person, the changed waiting time is notified to the first queuing person, and the second If you send the message to the meeting person, you can change the meeting time to a time when both parties do not delay, and one meeting person is likely to be late to change the meeting time. There is no need to contact the other meeting person.

  Further, as the movement status information of the moving body on which the second queuing person is riding, it is preferable that the movement status information of public transportation can be acquired as described in claim 6. In this case, as described in claim 6, the public transportation used by the second meeting person and the usage information for specifying the section where the second meeting person uses the public transportation are set. The second queuing person mobile body information acquisition means is based on the usage information set by the usage information setting means, and is used by the second queuing person. The movement status information in the section used by the second queuing person is acquired.

  As public transportation which acquires movement status information, there is an airplane or a train as described in claim 7 or 8. Further, as described in claim 9, vehicle movement status information may be acquired. Note that it is only necessary to be able to acquire the movement status information of either public transportation or a vehicle, but it is more preferable that both of the movement status information can be acquired.

  As described in claim 10, the information acquisition device according to any one of claims 1 to 9 is preferably provided in a navigation device. The navigation device is not limited to a vehicle navigation device, that is, a car navigation device, but may be a portable navigation device.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an overall configuration of a car navigation apparatus having a function as an information acquisition apparatus of the present invention.

Further, route guidance voice information and the like processed by the control device 8 are appropriately notified from the speaker 13 via the voice controller 12.

  Further, the control device 8 has a function of managing the waiting time when heading to a predetermined waiting place in time for the set waiting time.

  Next, a function for managing the waiting time will be described. 2 to 6 are flowcharts showing functions for managing the waiting time. When a predetermined waiting management function execution signal is input, first, the processing shown in FIG. 2 is executed.

  In FIG. 2, first, in step S10, a meeting place and a meeting time are acquired. Specifically, a screen for requesting an input of a meeting place and a meeting time that are negotiated in advance between a first meeting person who drives a vehicle equipped with this navigation device and a second meeting person that is a meeting partner. Is displayed on the display 10. Then, the place and time input as a result are stored in a storage device such as a RAM in the control device 8 as a meeting place and a waiting time.

  In the subsequent step S11, the mail address of the meeting partner is acquired. Specifically, an input screen is displayed on the display 10 and the input mail address is stored in a RAM or the like in the control device 8. In addition, by displaying a plurality of pre-stored e-mail addresses and having the user select one e-mail address from among the e-mail addresses, the e-mail address may be acquired, It may be stored in association with each other, a name may be input, and one mail address may be specified from the input name.

  In the subsequent step S12, the moving means used by the meeting partner is determined. Specifically, a message for inquiring the passenger about the use moving means of the meeting partner is output from the display 10, and the use moving means of the meeting partner is determined based on the input contents as a result.

  In subsequent step S13, based on the content determined in step S12, it is determined whether the use moving means of the meeting partner is a public transportation or a private vehicle. If the use moving means is a private vehicle, then the processing of FIG. 5 is executed.

  On the other hand, in the case of public transportation, in step S14 corresponding to the usage information setting means, usage information on the transportation used by the meeting partner is set. This usage information is information necessary to identify the operation status of the transportation facility and the section where the queuing partner uses the transportation facility. In the case of an aircraft, the flight number (for example, A company XX flight) In the case of a train, the train name and the boarding / exiting station (for example, Nozomi △△, ◎◎ boarding, getting off at Nagoya Station) are the usage information.

  In step S14, a message requesting input of the usage information is displayed on the display 10, and the content input as a result is set as usage information. Then, the process shown in FIG. 3 is executed.

  Next, the process shown in FIG. 3 will be described. First, in step S20, a route from the current location to the vehicle destination is calculated. When the vehicle destination is not set, the user is requested to set the vehicle destination when calculating the route. If the meeting place acquired in step S10 is a place where the vehicle can be directly reached, this vehicle destination becomes the meeting place, and the place where the meeting place cannot be directly reached by the vehicle (for example, in the station premises) ), It is set in a parking lot around the meeting place.

  In the subsequent step S21, an expected arrival time at the meeting place is set. Specifically, the estimated arrival time at the vehicle destination is calculated based on the route calculated in step S20. At the same time, a message for inquiring the required time from the vehicle destination to the meeting place is displayed on the display 10, and the time obtained by adding the input required time to the estimated arrival time at the vehicle destination is calculated as the expected arrival time at the waiting place. Is stored in a storage device such as a RAM in the control device 8.

  In subsequent step S22, the expected arrival time of the meeting place set in step S21 is compared with the waiting time acquired in step S10 to determine whether or not the waiting time needs to be changed. If the expected arrival time at the meeting place is later, this step S22 is affirmative and the process proceeds to step S23.

  In step S23, the waiting time acquired in step S10 is changed, the expected waiting time arrival time set in step S21 is set as a new waiting time, and the new waiting time is transmitted to the mail address acquired in step S11. Thereafter, the process proceeds to step S24.

  On the other hand, if the waiting time acquired in step S10 is later, step S22 is negative and the process proceeds directly to step S24.

  In step S24, the route guidance is started by executing the route guidance program. In subsequent step S25, information from the VICS center (VICS information) is received through the transceiver 11, and information on the vehicle position is acquired from the position detector 1. The information on the vehicle position is information indicating the current movement status of the vehicle, and the VICS information includes road traffic information such as traffic jam information. It is information that affects. Therefore, the information on the vehicle position and the VICS information are movement status information of the vehicle on which the navigation device is mounted.

  In a succeeding step S26, it is determined whether or not there is a traffic jam on the route based on the road traffic information included in the VICS information, the vehicle position information, and the route calculated in step S20. If this determination is negative, step S31 is executed directly.

  On the other hand, if the determination in step S26 is affirmative, in step S27, the estimated arrival time at the meeting place is recalculated in consideration of the distance of traffic jam, the speed of the traffic jam section, etc., and the estimated arrival time stored in step S21 is The recalculated time is changed to the expected arrival time at the meeting place.

  Subsequent step S28 corresponds to a first queuing person delay determination means, and compares the estimated arrival time changed in step S27 with the waiting time acquired in S10 of FIG. 2 or the waiting time changed in step S23. It is determined whether or not the waiting time needs to be changed. In the case of departure at a time sufficiently earlier than the waiting time, the waiting time may still be later even if the estimated arrival time is late. In this case, the determination in step S28 is negative and the process proceeds to step S31.

  On the other hand, if the estimated arrival time is later, step S28 is affirmative and the process proceeds to step S29. In step S29, the stored waiting time is updated to the estimated arrival time changed in step S27, and the new waiting time is output from the display 10 and the speaker 13 to notify the driver of the new waiting time. To do.

  In the subsequent step S30, the waiting time updated in step S29 and the current position of the vehicle are transmitted to the mail address of the waiting partner acquired in step S11. Thereby, the meeting partner can also know that the meeting time has been changed.

  And after execution of step S30 or after negative determination of step S26 or step S28, it is determined whether it arrived at the vehicle destination in step S31. If this determination is negative, step S25 and subsequent steps are executed to repeat the determination as to whether route guidance or waiting time needs to be changed. On the other hand, when step S31 is affirmative determination, this routine is complete | finished.

  FIG. 4 is a process executed in parallel with the process shown in FIG. 3 by an interrupt process or the like, and is a process for determining whether or not there is a possibility that the queuing partner will be delayed.

  First, in step S40, the transmitter / receiver 11 is connected to a public communication line or transmitted / received to / from the VICS sensor, and based on the usage information set in step S14 of FIG. Get movement status information. In the case of transportation, this movement status information is information indicating whether the vehicle is operating normally or has a delay, and if there is a delay, how much delay has occurred.

  In the subsequent step S41, it is determined whether or not there is a delay in the transportation facility used by the meeting partner based on the movement status information acquired in step S40. If this determination is negative, the process in FIG. 4 is terminated.

  On the other hand, if the determination in step S41 is affirmative, in step S42, an expected time at which the meeting partner arrives at the meeting place is determined based on the movement status information acquired in step S40. In addition, when the place where the meeting partner finishes using the transportation facility and the meeting place are different, the estimated time at which the meeting partner arrives at the meeting place is determined in consideration of the travel time for walking between them.

  In step S43, the expected arrival time determined in step S42 is compared with the waiting time acquired in step S10 in FIG. 1 or the waiting time changed in step S23, and the waiting partner is not in time for the waiting time. Determine whether or not.

  If the initial meeting time is set sufficiently later than the time when the meeting partner arrives at the meeting place, such as when the expected arrival time determined in step S42 is late but the meeting time is still later In step S43, a negative determination is made, and this routine is terminated.

  On the other hand, if the estimated arrival time determined in step S42 is later than the waiting time, step S43 is affirmative, and in step S44, the waiting time stored in a storage device such as a RAM in the control device 8 is determined. The expected arrival time of the meeting partner determined in step S42 is changed.

  In step S45, the waiting time is changed because the waiting party is delayed, and the waiting time after the change is output to the speaker 13 and the display 10, thereby informing the driver.

  Furthermore, in step S46, the waiting time changed in step S44 is transmitted to the mail address of the waiting partner acquired in step S11 of FIG. Thus, even if the meeting partner does not notify the delay by itself, the meeting time is changed according to the delay of the transportation facility on which he / she is riding, and both the persons who wait for the changed meeting time at the meeting place I can know.

  3 and 4, step S25 corresponds to the first queuing person mobile body information acquisition means, step S27 corresponds to the first queuing person arrival expected time determination means, S28 corresponds to the first queuing person delay determination means. Step S40 corresponds to the second queuing person mobile body information acquisition means, step S42 corresponds to the second queuing person arrival expected time determination means, and step S43 corresponds to the second queuing person delay determination means. Steps S29 and S44 correspond to time change means, steps S29 and S45 correspond to change time notification means, and steps S30 and S46 correspond to change time transmission means.

  Next, the processing of FIG. 5 executed when it is determined in step S13 of FIG. 2 that the use moving means of the meeting partner is a private vehicle will be described.

  First, in step S50, it is determined whether or not communication with the communication device of the vehicle of the other party is possible. This is determined, for example, based on whether or not the partner vehicle is equipped with the same transceiver 11 as that of the present vehicle and the address of the partner transceiver 11 is acquired on the communication line.

  If this determination is affirmative, in step S51, information regarding the current location of the other party is acquired by performing transmission / reception with the other party's communication device. On the other hand, if the determination in step S50 is negative, in step S52, a screen requesting input of the current position of the meeting partner is displayed, and as a result, the point input by the user is acquired as the current position of the meeting partner.

  After step S51 or step S52 is executed, in step S53, the route until the host vehicle arrives at the vehicle destination is calculated, and the route until the queuing partner vehicle arrives at the vehicle destination is also calculated.

  In step S54, an estimated time for the vehicle to arrive at the vehicle destination is calculated based on the route of the vehicle calculated in step S53, and a message for inquiring the required time from the vehicle destination to the meeting place is displayed. 10, the time obtained by adding the required time input as a result to the estimated arrival time at the vehicle destination is set as the expected arrival time at the meeting place and stored in a storage device such as a RAM in the control device 8.

  Further, in step S54, an expected time at which the meeting partner arrives at the vehicle destination is calculated based on the route of the meeting partner calculated in step S53, and from the vehicle destination input by the user to the meeting place at that time. Is set as a predicted arrival time of the meeting partner and stored in a storage device such as a RAM in the control device 8.

  In subsequent step S55, it is determined whether or not it is necessary to change the waiting time by comparing the two waiting time arrival arrival times set in step S54 with the waiting time acquired in step S10 of FIG. . If the two expected arrival times at the meeting place are both earlier than the waiting time, the determination in step S55 is negative, and step S57 is directly executed.

  On the other hand, if at least one of the two expected arrival times for the meeting place is later than the waiting time, step S55 is affirmative and step S56 is executed.

  In step S56, the waiting time acquired in step S10 of FIG. 2 is changed to a later time among the two expected waiting time arrival times set in step S54. Further, the changed waiting time is displayed on the display 10 to notify the user of the host vehicle, and is transmitted to the mail address of the waiting partner acquired in step S11 of FIG.

  Subsequently, step S57 and subsequent steps shown in FIG. 6 are executed. In step S57, route guidance is started by executing the route guidance program. In the subsequent step S58, the VICS information from the VICS center is received via the transceiver 11. This VICS information includes information indicating whether or not there is a traffic jam on the route on the own vehicle side and the route on the other party side, and these are movements that affect the future movement status of the own vehicle and the other vehicle. It is status information.

  In step S59, based on the road traffic information included in the VICS information and the route on the own vehicle side and the other side calculated in step S53, it is determined whether or not there is traffic on any one of the routes. to decide. If this determination is negative, step S65 is executed directly.

  On the other hand, if the determination in step S59 is affirmative, in step S60, the estimated arrival time on the side where the traffic jam occurs is recalculated in consideration of the traffic jam distance, the speed of the traffic jam section, etc., and is set in step S54. The expected arrival time at the meeting place is changed to the recalculated estimated arrival time. Then, the changed expected arrival time of the meeting place is output from the display 10 and the speaker 13 together with the distinction between the own vehicle side and the waiting party side, thereby informing the user.

  Further, in step S61, the waiting time is changed by comparing the expected arrival time of the waiting place changed in step S60 with the waiting time acquired in step S10 of FIG. 2 or the waiting time changed in step S56 of FIG. Determine if it is necessary.

  If the meeting time is set with a margin, such as when the expected arrival time at the meeting place is late, but the meeting time is still later, step S61 is negative, and in this case, step S65 is directly executed. Execute.

  On the other hand, when the expected arrival time at the meeting place changed in step S60 is later than the waiting time, step S61 is affirmative and step S62 is executed. In step S62, the waiting time is changed to the expected arrival time.

  Then, in the subsequent step S63, a message indicating that the waiting time has been changed is output from the display 10 and the speaker 13, and this is notified to the driver. Further, in step S64, when it is determined that the waiting time changed in step S62 can communicate with the mail address acquired in step S11 of FIG. 2 or the communication device of the counterpart vehicle in step S50 of FIG. To the address of the communication device, or both.

Step S61 corresponds to first and second queuing person delay determination means. Step S62 corresponds to time change means, step S63 corresponds to change time notification means, and step S64 corresponds to change time transmission means.

  As described above, according to the present embodiment described above, the movement status information of the moving body used by the queuing partner is acquired in step S40 or S58, and in step S42 or S60, the meeting is performed based on the acquired movement status information. Since the expected arrival time of the other party's meeting place is determined, the user who is driving this vehicle can know that the other party will be late for the waiting time even if the other party does not tell his / her expected arrival time .

  Further, according to the present embodiment, the movement status information of the own vehicle is acquired in step S25 or S58, and in step S27 or S60, arrival of the waiting place on the own vehicle side based on the acquired movement status information of the own vehicle. Estimated time is determined. In S29, S44, and S62, the waiting time is changed based on the expected waiting time arrival time of the waiting party and the waiting time arrival arrival time of the own vehicle, and the changed waiting time is notified to both waiting people. (Steps S29, S30, S63, S64). Therefore, the meeting time can be changed at a time when both are not delayed, and in order to change the waiting time, one meeting person needs to inform the other meeting person that he is likely to be late. Absent.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the above-mentioned embodiment, The following embodiment is also contained in the technical scope of this invention, and also the summary other than the following is also included. Various modifications can be made without departing from the scope.

  For example, in the above-described embodiment, when the expected waiting time arrival time is changed, the changed expected waiting time arrival time is compared with the waiting time, and if necessary, the waiting time is changed. Although the changed waiting time is notified, the changed arrival predicted time may be simply notified without comparing the waiting time arrival time with the waiting time. Normally, since the user stores the waiting time, even if the user simply notifies the changed estimated arrival time, the user stores the notified expected arrival time at the waiting place. Compare with the meeting time, and if necessary, you can contact the meeting person yourself.

  In the above-described embodiment, the information acquisition device is provided in the navigation device, and the first queuing person drives a vehicle equipped with the navigation device, but the information acquisition device may be a portable type. Good. In this case, the first meeting person can also use a moving body other than a vehicle such as a train as the moving body. Moreover, it may be on foot without using a moving body.

  In the above-described embodiment, the case where there are two persons waiting for each other has been described as an example, but three or more persons may be used.

  In the above-described embodiment, an example has been described in which the queuing partner uses only one of public transportation or a vehicle as a moving body. However, a combination of the two may be used. In step S58, the current position of the meeting partner may be acquired sequentially.

It is a block diagram which shows the whole structure of the car navigation apparatus provided with the function as an information acquisition apparatus of this invention. It is a flowchart which shows the function which manages the waiting time of the control apparatus 8, Comprising: It is a flowchart which shows the process performed initially.
