Is a guide light that indicates that the vehicle 3 is being advanced, 11B is a safety light that indicates that the vehicle 3 is at a position where elevator operation can be registered in the car, and 11D is a buzzer.

Next, the operation will be described with reference to FIG. It should be noted that here, description will be given of storage in the car on the first floor.

In FIG. 12, when the door 1A of the hall on the first floor is open, the vehicle 3 starts getting into the car 5 at step 71, and the photoelectric device 6 in the car provided at the entrance side of the car 5 at step 72. Vehicle 3 by blocking the optical axis of
When detecting, the first detection signal is sent to the elevator controller 1
Then, in step 73, the elevator control device 13 turns on the arrow light 11A of the car operation guide board 11 and advances the vehicle 3 in the arrow direction of the arrow light 11A.

After that, when the optical axis of the in-car photoelectric device 6 provided on the entrance side is not blocked and the vehicle 3 cannot be detected,
When the output of the first detection signal is completed, the arrow lamp 11A of the car operation guide board 11 is turned off in step 74, accordingly.
The safety light 11B indicating that the vehicle 3 is within the range of the car 5 that does not interfere with the traveling of the elevator is turned on, and the vehicle 3 is stopped.

Then, when the user and the staff of the vehicle elevator register the car call on the second floor of the car operation guide panel 11, the door 1A of the hall is closed in step 75 and the car 5 runs.

After that, the first in-car photoelectric device 6 determines whether or not the optical axis of the first in-car photoelectric device 6 is blocked, as in step 76, in order to prevent a danger due to movement of the vehicle while the car 5 is traveling. If it is determined that the optical axis is not blocked and the vehicle 3 is not detected, the car 5 continues to run, stops at the second floor in step 78, opens the door 2A at the second floor hall, and ends the vehicle transportation.

However, at step 76, the vehicle 3 sways or moves due to factors such as the sway of the elevator operation, forgetting to pull the side brakes of the vehicle 3 and the unsatisfactory foot pedal depression. Photoelectric device 6
When the vehicle 3 again interrupts the optical axis of 1 and the first detection signal is output, the car 5 immediately stops in step 77.

Conventionally, this type of vehicle elevator has generally not been provided with a door on the side of the car 5;
Under the configuration as disclosed in Japanese Utility Model Laid-Open No. 57-147951, an in-car photoelectric device 6 for detecting that the vehicle 3 is at a position permitting the elevator car 5 to move up and down is arranged. When the first in-car photoelectric device 6 detects the vehicle 3, the elevator cannot be operated for ensuring safety. Further, the car 5 is designed to immediately stop when the photoelectric device 6 in the car detects the vehicle 3 during transportation of the car.

[0012]

As described above, in the conventional vehicle elevator, when the optical axis of the first in-car photoelectric device is blocked by the vehicle, the first detection signal is output and the first detection signal is output.
The guide light of the car operation guide panel is displayed based on the output signal of the vehicle, and the elevator user for the vehicle is instructed to move the vehicle according to the displayed contents. Then, when the optical axis of the first in-car photoelectric device is no longer blocked by the vehicle, the output of the first detection signal ends, and along with that, the safety light on the car operation guide panel is displayed and the guidance of the vehicle ends. I have to.
Therefore, the user of the vehicle elevator stops the movement of the vehicle immediately after the guide light ends. As a result, the vehicle may stop at a position immediately after blocking the optical axis of the first in-car photoelectric device. Then, in such a case, the vehicle is shaken by the operation of the car, forgets to pull the side brakes, or moves the vehicle due to the uncomfortable stepping of the foot brake, that is, does not hinder the elevator operation in the car. Moreover, even if the optical axis of the first in-car photoelectric device is moved to a vehicle end portion (for example, by a slight movement within a range in which there is no problem in terms of safety (hereinafter referred to as a lifting permission range),
When a vehicle is detected by being blocked by a bumper or the like), the car has an emergency stop.

When the user is in the vehicle and is transporting the vehicle, there is a safety problem due to the anxiety of the user due to the emergency stop of the car due to the above-mentioned problems, and the user again has the car. It is necessary to move the vehicle again according to the indication of the guide light lit along with the emergency stop of the car and register the car call again, and there is a waste of time. Then, there has been a problem that the vehicle elevator maintenance manager has to call back the car and repeat the above-described series of operations, which causes the same wasteful time as described above.

The present invention has been made to solve the above-mentioned problems, and even an automatic vehicle guidance type vehicle elevator using the first in-car photoelectric device (first vehicle detection device). Provided is a vehicle elevator control device capable of safely transporting a vehicle to a predetermined floor without wasteful time without making an emergency stop of the car when the vehicle is slightly moved within the elevator up / down permitted range. The purpose is to do.

【Example】

Example 1. FIG. 1 is a block diagram showing an embodiment according to the present invention. In the figure, 1 to 6 are exactly the same as the above-mentioned conventional example. Reference numeral 7 indicates a third distance (second distance + second distance + second distance + second distance + second distance + second distance + second distance + distance) between the rear end of the vehicle 3 in the traveling direction and the first in-car photoelectric device 6 are separated by a second distance (first distance + elevation permission range, for example, 210 mm). It has a light emitter and a light receiver installed on the left and right of the inner wall of the car with the total length (4700 mm) of the general vehicle 3 corresponding to the car 5 placed, for example, 4910 mm, and the optical axis is blocked by the light emitter and light receiver on the left and right of the car inner wall. The second in-car photoelectric device that detects the vehicle 3 depending on whether or not the vehicle 3 is detected, outputs the second detection signal only when the vehicle 3 is detected, and permits the operation of the car 5, 11 is the first car When the first photoelectric detection device 6 outputs the first detection signal, the arrow lamp 11A for guiding the vehicle 3 is turned on, and the second internal photoelectric device 7 outputs the second detection signal for the first time. Turn off the arrow light 11A, and drive the car 3 It is a safety light 11B the lights or your operation guide panel which indicates that it is within the permitted range.

Next, in the first embodiment described above. Will be described with reference to the operation flowchart of the elevator shown in FIG. 6 stored in the ROM of the microcomputer.

First, in step 1, the vehicle 3 gets into the car 5. When the vehicle 3 gets into the car 5, in step 2, for example, a pair of first in-car photoelectric devices 6 shown in FIG. 13 mounted at positions 200 mm from the doorway and 200 mm in height on the left and right of the car inner wall. It is determined whether or not the optical axis emitted by the vehicle 3 is blocked by the vehicle 3, and when the optical axis is blocked, that is, when the vehicle 3 is detected, the first detection signal is output, and step 3 is performed based on the signal.
Thus, the arrow lamp 11A of the car operation guide panel 11 is turned on to guide the vehicle 3.

After guiding the vehicle in step 3, when the vehicle 3 advances in the car 5 to a position where the optical axis is not blocked, that is, the vehicle 3 is not detected by the first in-car photoelectric device 6, the car 5 in step 4 is moved. When the optical axis of the second in-car photoelectric device 7 installed at a third distance (for example, 4910 mm) from the doorway is blocked, and the optical axis is not blocked, that is, the vehicle 3 is not detected Continues until the vehicle guidance in step 3 is continued, and the second in-car photoelectric device 7 detects the vehicle 3 in step 4 and continues until the second detection signal is output.

This time, the minimum distance between the first in-car photoelectric device 6 and the end of the vehicle was set to 10 mm, and the ascending / descending range was determined. However, the arrow lamp 11A was turned off and the safety lamp 11B was turned on, and the The installation position of the second in-car photoelectric device 7 may be determined by obtaining the minimum distance between the first in-car photoelectric device 6 and the vehicle end in consideration of the reaction time of stepping on the brake.

When the second in-car photoelectric device 7 outputs the second detection signal in step 4, in step 5, the arrow lamp 11A of the car operation guide panel 11 is turned off and the safety lamp 11B is turned on to turn on the vehicle 3. End the induction. After that, when the user of the vehicle elevator registers the car operation information panel 11 or the desired floor by the elevator manager, the doors are closed and the car 5 can run, the elevator runs in step 6, and step 18 When the car 5 stops on the floor desired by the user, the door on the desired floor is opened and the vehicle transportation is completed.

Unlike the first in-car photoelectric device 6, the second in-car photoelectric device 7 here does not serve as an up-down operation permission (safety device) for the car 5. In other words, the second in-car photoelectric device 7 outputs the second detection signal to stop the vehicle guidance when the vehicle 3 is detected by the optical axis, but once the elevator operation is registered and the car 5 When the vehicle starts traveling, the second in-car photoelectric device 7 does not block the optical axis due to a slight movement of the ascending / descending range, and even if the vehicle 3 is no longer detected, the car 5 does not make an emergency stop. When the optical axis of the in-car photoelectric device 6 detects the vehicle 3, that is, the vehicle 3 moves up and down the permitted range (this time, 10
The elevator operation is stopped urgently by step 8 only when the vehicle has moved more than 10 mm.

Example 2. Example 1 above. Then, the first in-car photoelectric device 6 is installed at a position at a first distance (200 mm) from the entrance / exit of the car 5, and the second in-car photoelectric device 7 is installed at the third position on the back side of the car 5. Position (4910m
m) is installed at the position where the second in-car photoelectric device 7 is located at the front end of the vehicle 3 in the traveling direction (the front end of the vehicle).
Is detected, the ascending / descending range is separated even if the distance between the rear end of the vehicle 3 on the traveling direction side (the rear end of the vehicle) and the first in-car photoelectric device 6 is at least. This example 2. Then, the first in-cage photoelectric device 6 is the same as in the first embodiment. The second in-car photoelectric device 8 is installed at a second distance, but when the vehicle 3 is no longer detected, the second in-car photoelectric device 8 and the first rear side end portion of the vehicle 3 in the traveling direction and the first end are disposed. The second distance is set so that the distance of the photoelectric device 6 in the car is separated from the lifting permission range.

FIG. 2 is a block diagram showing another embodiment of the present invention. In the figure, 1 to 6 are exactly the same as the above-mentioned conventional example. The second car 8 is installed at a second distance, outputs the detection signal 2a when the vehicle 3 is detected in the same manner as the in-car photoelectric device 6, and then disables the function of detecting the vehicle 3. An internal photoelectric device, 11 lights an arrow lamp 11A for guiding the vehicle 3 when the first detection signal is output from the first in-car photoelectric device 6, and the first in-car photoelectric device is turned on. Even if the first detection signal is not output from 6, the arrow lamp 11A is continuously lit while the second in-car photoelectric device 8 is outputting the 2a detection signal. After that, when the 2a detection signal of the second in-car photoelectric device 8 is no longer detected, the arrow light 11A is turned off, and the safety light 11B indicating that the vehicle 3 is within the safe range is turned on. is there.

Next, in the second embodiment described above. Will be described with reference to the elevator operation flowchart of FIG. 7 stored in the ROM of the microcomputer.

Example 1. Steps 1 and 11 of
Step 3 and Step 13, Step 5 and Step 1
Since step 4 and step 6 and subsequent steps are the same as step 16 and subsequent steps, the description thereof will be omitted except step 12 and step 15. In Step 12, even if the first in-car photoelectric device 6 does not detect the vehicle 3 and does not output the first detection signal due to the vehicle guidance in Step 3, the second distance is set and the inside of the car 5 is stopped. First in-cage photoelectric device 6
As long as the optical axis of the second in-car photoelectric device 8 installed at the same height is blocked and the vehicle 3 is detected, the second detection signal is output. As long as this 2a detection signal is output, the vehicle guidance by the arrow lamp 11A in step 13 is continued.

After that, when the optical axis of the second vehicle detection device 8 is not blocked and the second in-car photoelectric device 8 cannot detect the vehicle 3, the output of the second detection signal is terminated,
Go to step 14 and subsequent steps. When the second in-car photoelectric device 8 cannot detect the vehicle 3, the distance between the vehicle 3 and the first in-car photoelectric device 6 is the minimum because of the installation position of the second in-car photoelectric device 8. But 10mm away.

After that, when the user of the vehicle elevator registers the car call by using the car operation guide panel 11, or the elevator manager registers the desired floor, the door is closed and the car 5 can run. Second in step 15
The capability of outputting the 2a detection signal while the in-car photoelectric device 8 detects the vehicle, and not permitting the elevator car 5 to move up and down while the 2a detection signal is output. It is automatically switched and disabled. That is, even if the second in-car photoelectric device 8 detects the vehicle 3 while the vehicle 3 is traveling in the car, an emergency stop is prevented.

In addition, in order to prevent the second in-car photoelectric device 8 from detecting the vehicle 3 while the car is traveling and causing an emergency stop, the second in-car photoelectric device 8 is Two
The detection signal of a does not have the authority to permit elevator operation
The same effect can be obtained by setting the control so that only the guiding device is controlled. That is, the first in-car photoelectric device 6
When the first detection signal is no longer output, the car 5 is actually in the travel-enabled state, but since the arrow lamp 11A is lit and the vehicle guidance is continued, the car call is not registered. . In this case, in the above-mentioned Embodiment 2. There is no need to switch automatically as in.

Furthermore, in the second embodiment. In the above description, the control of the second in-car photoelectric device 8 is switched by a program in the microcomputer. However, the car operation is linked with the car operation guide panel 11 for registering a car call, or a mechanical changeover switch is provided to perform a human operation. The same effect can be obtained by switching by.

In step 15, the second in-car photoelectric device 8 is invalidated, but the first in-car photoelectric device 6 is not invalidated.
It will continue to serve as a safety device. By doing so, even if the vehicle 3 moves on the optical axis of the second in-car photoelectric device 8 for a slight movement of the travel permitted range, the elevator operation is not affected, and the risk of the vehicle 3 involving danger is increased. The first vehicle detection device 6 reacts to a large movement beyond the travel permitted range, and the elevator operation is stopped urgently.

Example 2 above. I explained that the entrance and exit of the car 5 is in one direction, but the entrance and exit is in two directions,
Along with that, the same effect can be obtained even if the first and second in-car photoelectric devices are plural. The case where the doorways of the car 5 are in two directions will be described below.

FIG. 3 is a block diagram when the entrance and exit of the car 5 is in two directions, and 6 and 6A are the first in-car photoelectric devices installed at a first distance from the respective entrances and exits, as in the above embodiment. Similarly, the devices 8 and 8A are the second in-car photoelectric devices installed at the second distance from the respective entrances and exits. FIG. 8 is an operation flowchart of the elevator when the entrance and exit are in two directions, which will be described below with reference to this flowchart.

Steps 21 to 23 and Steps 11 to 1
3. Since steps 27 to 32 and steps 14 to 19 are exactly the same as those in the above embodiment, steps 24 to 2 are executed this time.
6 will be described. Here, the entrance and exit of the car 5 is in two directions, but when the vehicle 3 enters the car 5,
In order to prevent congestion of the vehicle 3 waiting for the car, only one of the two-way doorways is opened. Therefore, in the description of the present embodiment, the first photoelectric device in the car that detects the vehicle 3 when the vehicle 3 comes in is 6, the photoelectric device in the second car is 8, and the photoelectric device in the second car is 8. In the following description, the first in-car photoelectric device on the side of the traveling direction, that is, the door side of the car 5 that has not been opened this time is 6A, and the second in-car photoelectric device is 8A.

In step 22, the first in-car photoelectric device 6 and the second in-car photoelectric device 8 on the entrance side of the car 5 no longer detect the vehicle 3, and the first detection signal and the second detection signal are detected. When the output is no longer output, the routine proceeds to step 24, where the first in-car photoelectric device 6A and the second in-car photoelectric device 8A on the back side with respect to the entrance / exit of the car 5 cause the vehicle 3 to operate.
The optical axis is blocked by and it is determined whether or not the vehicle 3 is detected. If the vehicle 3 is detected, since the 1b-th detection signal and the 2b-th detection signal are output, the elevator car 5 is not permitted to move up and down based on these signals, and the step 2
The vehicle guidance by the arrow light 11A of 3 is stopped, and the step 2
The vehicle 3 is guided by the arrow lamp 11C in the direction of the entrance and exit of the car 5 of 5, that is, in the direction opposite to the direction in which the vehicle has been guided so far.

As a result of the vehicle guidance in step 25, the vehicle 3 is installed in the first car photoelectric device 6A and the second car photoelectric device 8 in the car.
When A is no longer detected, in step 26, the vehicle 3
Is detected by the first in-car photoelectric device 6 and 6A and the second in-car photoelectric device 8 and 8A, the vehicle 3 is not detected in any of the in-car photoelectric devices,
If the first and 1b, 2a, and 2b detection signals are not output, the process proceeds to step 27 and subsequent steps similar to the above embodiment.

If any of the photoelectric devices in the car detects the vehicle 3 in step 26, the process returns to step 22, and steps 22 to 26 are repeated.
The vehicle 3 is guided to a position where it is not detected by any of the above-described in-car photoelectric devices, and step 27 and subsequent steps are performed. According to the above steps, the vehicle 3 is stopped at a position at least 10 mm or more away from the first in-car photoelectric devices 6 and 6A as the safety device of the vehicle 3, so that the vehicle is not operated due to the elevator operation or forgetting to pull the side brake. For a little movement of 3,
Even if the vehicle 3 moves on the optical axes of the second in-car photoelectric devices 8 and 8A, the elevator operation is not affected, and the first vehicle detection device 6 or 6A is used for a large movement of the vehicle 3 which is dangerous. Reacts and stops the elevator operation in an emergency.

Example 3. FIG. 4 is a block diagram showing another embodiment of the invention. In the figure, except for 10, the description is omitted because it is the same as the above embodiment. 10 is the first
It is a delay circuit that is an extension device that receives the first detection signal of the in-car photoelectric device 6 and outputs the first detection signal with a time shift.

Next, in the above third embodiment. Will be described with reference to the elevator operation flowchart of FIG. 9 stored in the ROM of the microcomputer.

Steps 41 to 43 and step 7
Since steps 1 to 73, steps 45 to 49, and steps 74 to 78 are exactly the same as those in the conventional example, step 44 will be described. According to step 42, while the first in-car photoelectric device 6 is detecting the vehicle 3, the first detection signal is output, but the vehicle 3 is guided by the arrow lamp 11A and the first in-car When the photoelectric device 6 no longer detects the vehicle 3, in step 44, the first detection signal of the first in-car photoelectric device 6 is output even after the first in-car photoelectric device 6 no longer detects the vehicle 3. The output of the first detection signal is extended by the delay time set by the delay circuit 10 and is output because it passes through the delay circuit 10 that delays the input for a predetermined time. Accordingly, although the first in-car photoelectric device 6 does not actually detect the vehicle 3, the arrow light 11A of the car operation guide panel 11 lights up for the delay time and the vehicle guidance continues. Since the vehicle guidance is continued by the arrow light 11A for the delay time, the vehicle 3 moves to the position separated by the second distance, and the vehicle end and the first
The photoelectric device 6 in the car is separated by the travel permitted range.

After that, when the delay time set by the delay circuit 10 elapses, the first signal passed through the delay circuit 10.
Since the detection signal of is not output, the car operation guide panel 1
The arrow light 11A of No. 1 is turned off and the safety light 11B is turned on to notify that the vehicle 3 is separated by the second distance. Subsequent steps are the same as those in the above-mentioned conventional example, and therefore description thereof will be omitted.

Here, the method of determining the delay time to be delayed is obtained from the average speed at which the vehicle 3 gets into the vehicle elevator and is guided, and the travel permitted range. For example, the statistical average speed of the vehicles 3 boarding the car 5 is 360 m /
Assuming that the travel permission range is 5 cm, the delay time is calculated to be 0.5 seconds or more. The value of 0.5 seconds or more is shifted in time by the delay circuit 10. Further, instead of the delay circuit 10, a circuit such as a counter or a program of a microcomputer may detect the above-mentioned delay time.

Other methods of determining the delay time to be delayed are as follows.
In step 42, the time from when the first in-cage photoelectric device 6 starts detecting the vehicle 3 until the detection ends is measured by the control device or the counter, and the delay time corresponding to the time when the vehicle 3 is detected is determined. Take out from the map of the microcomputer that has been calculated in advance. (For example,
The time during which the first in-car photoelectric device 6 has detected the vehicle 3 is 47 seconds, and the total length of the vehicle corresponding to the car 5 is 47 seconds.
If it is 00 mm, the vehicle 3 has traveled 4.7 m in 47 seconds, so the average speed is 360 m / h. This average speed 360
Assuming that the minimum distance between the first in-car photoelectric device 6 and the vehicle end is 5 cm at m / h, the delay time is 0.5.
Determined in seconds)

Example 3 above. Although the case where the entrance and exit of the car 5 has one direction has been described above, the same effect can be obtained even if the first and second photoelectric devices in the car have a plurality of entrances and exits in two directions.

FIG. 5 is a block diagram showing the case where the doorways of the car 5 are in two directions. In FIG. 4, which is the configuration diagram of FIG. 4, the first in-car photoelectric device 6A is installed at a position separated from the other doorway for the first period. FIG. 10 shows the third embodiment in the case where the doorways are in two directions. 11 is an operation flowchart of the elevator, and will be described below with reference to the flowchart of FIG.

Here, the entrance and exit of the car 5 is in two directions, but when the vehicle 3 enters the car 5, only one of the two directions of entrance and exit is provided in order to prevent congestion of the car 3 waiting for the car. will not open. Therefore, in the present embodiment, the vehicle 3 comes into the car 5, and the vehicle 3 comes first.
6 will be described as the first in-cage photoelectric device which detects that, and the first in-cage photoelectric device on the side of the traveling direction of the vehicle 3, that is, the door side of the car 5 that has not been opened this time as 6A. .

In FIG. 10, steps 55 to 57 are the same as those in the third embodiment. Since it is provided between step 44 and step 45, the description is omitted except for step 55, step 56, and step 571. Since the vehicle guidance continues for the delay time even after the first in-car photoelectric device 6 no longer detects the vehicle 3 in step 54, the vehicle 3 advances too far in the car 5 within the delay time. There is also possible. Therefore, in step 55, it is determined whether or not the first in-car photoelectric device 6A on the back side of the car 5 with respect to the entrance side detects the vehicle 3. If the vehicle 3 is not detected,
Step 57 is ignored as it is, and the process proceeds to step 58 and thereafter. Here, step 57 is ignored because the vehicle guidance is performed by shifting the delay time period by the output of the delay circuit 10 using the detection signal 1b of the first in-car photoelectric device 6A as an input. This is because the 1bth detection signal is not output unless the vehicle 3 is detected by the in-car photoelectric device 6A.

When the vehicle 3 moves too far in the car 5 and the first in-car photoelectric device 6A detects the vehicle 3, the 1bth detection signal is output. While the 1b detection signal is being output, the elevator car 5 is not permitted to move up and down. Therefore, in order to eliminate the state in which the elevator car 5 is not allowed to move up and down, the arrow lamp 11C is turned on in step 56. , The vehicle 3 in the direction opposite to the arrow light 11A in step 53
Induce. As a result of vehicle guidance by the arrow light 11C, the first
Even if the photoelectric device 6A in the car does not detect the vehicle 3,
The vehicle guidance is continued for 0.25 seconds (half the delay time determined in step 7; hereinafter referred to as delay time A). The delay method of 0.25 seconds is the same as in the third embodiment. As described above, by outputting the 1bth detection signal via the delay circuit 10, the delay circuit 10 outputs 0.25
The guidance time of the arrow lamp 11C is extended by the number of seconds.

The delay time A for guiding the vehicle in the opposite direction by the arrow lamp 11C is the same as the delay time in step 54, but the vehicle 3 may be detected again by the first in-car photoelectric device 6. Therefore, the explanation has been made by deciding the time period to be half of the delay time of step 54, but what should be considered in determining the delay time A is a short time equal to or less than the delay time of step 54 and the delay time A The vehicle 3 is prevented from being detected by the first in-car photoelectric device 6 by the vehicle guidance by. In other words, any delay time may be set as long as the vehicle 3 is not detected again by the first in-car photoelectric device 6 due to the extension of the vehicle guidance by the delay time A.

Subsequent steps are the same as those in the above-mentioned embodiment, and the description thereof will be omitted.

Embodiment 1 as described above. Example 2. Example 3. Then, the guidance device was used as a car operation guide panel, and the vehicle was guided by the arrow lights 11A and 11C. However, the guidance device was used to sound the buzzer 11D, a sounding device such as a speaker, or an arrow light and a sounding device to position the vehicle. It is also possible to do so.

As described above, according to the present invention, when the vehicle is positioned in the car, the first vehicle detection device separates the vehicle by the first distance, which does not hinder elevator up and down operation. Even after detecting that the vehicle has reached the position, it is located further inside than the doorway of the car more than the first distance in consideration of the movement of the car due to the shaking of the car or the incomplete vehicle stop state. Since the vehicle is guided to the inside of the second distance, the vehicle does not stop immediately after the first vehicle detection device, and when the car is traveling, if the car moves within the travel permission range, Since there is no emergency stop, the vehicle can be safely transported to the desired floor in the shortest time.
