The direction shown) visual recognition pecten 15a and pedal 11 example.
The example that a part for pedal 11 is floated is shown in Fig. 6 A.At this moment, according to displacement detecting sensor 17, step on
The displacement D1 of plate 11 becomes to be used for the displacement D0 that basis displacement is recorded in record portion 22 short.
The example of example that a part for pedal 11 floated and the part shortcoming of pedal 11 is shown in Fig. 6 B.
In fig. 6b at the position 20a of amplifying observation, each displacement detecting sensor 17 of displacement detecting portion 16a possesseds is schematically illustrated
Measure the displacement D1 of pedal 11 situation.
For example, in the case where the displacement deviateed from basis displacement is ± 2mm, although pedal 11 and broach 18 directly connect
Tactile possibility is low, but needs to point out attendant of apparatus of passenger conveyor 1 etc..Therefore, if will be relative to benchmark position
± 2mm the scope moved is set to threshold value th1, then operational part 23 is when the displacement deviateed from basis displacement exceeds threshold value th1 pair
Monitoring unit 10 sends alarm.In addition, for example, the displacement deviateed from basis displacement be ± 4mm in the case of, pedal 11 and comb
The possibility that tooth 18 directly contacts improves.Therefore, if the scope of ± 4mm relative to basis displacement is set into threshold value th2, transport
Calculation portion 23 stops the operating of apparatus of passenger conveyor 1 when the displacement deviateed from basis displacement exceeds threshold value th2.In addition, also may be used
So that threshold value th1, threshold value th2 are different with the displacement in -Z direction in +Z direction relative to basis displacement.
In fig. 6b at the position 20a of amplifying observation, show to reach the peak of pedal 11 because floating a part for pedal 11
To threshold value th1 situation.At this moment, the displacement D1 detected by displacement detecting sensor 17 is than the displacement D0 that is represented with basis displacement
Short, the displacement deviateed from basis displacement exceeds threshold value th1.Therefore, alarm is sent by operational part 23.
In addition, in fig. 6b at the position 20b of amplifying observation, the peak of the shortcoming of pedal 11 reaches threshold value th1.At this moment, position
The displacement D2 moved detected by detection sensor 17 is longer than the displacement D0 represented with basis displacement, the displacement deviateed from basis displacement
Amount exceeds threshold value th1.In this case alarm is also sent by operational part 23.

Detection sensor 17 is abbreviated as " sensor ".In addition, in the processing shown in Fig. 7, it is main to illustrate that use is arranged at upside and come in and gone out
Floor 3a displacement detecting portion 16a example, on using the position for being arranged at downside discrepancy floor 3b for carrying out same action
The example for moving test section 16b then omits the description.
First, control unit 7 judges whether apparatus of passenger conveyor 1 is in operating (S1).It is not operating in apparatus of passenger conveyor 1
In in the case of (S1 "No"), control unit 7 continues step S1 processing.In the case where apparatus of passenger conveyor 1 is in operating
(S1 "Yes"), displacement detecting sensor 17 detect the displacement (S2) of pedal 11.Represent detected by displacement detecting sensor 17
The sensor output signal of displacement of pedal 11 be sent to control unit 7.
The signal receiving part 21 of control unit 7 receives sensor output signal, and sensor output signal is transformed into pedal 11
Displacement.Then, operational part 23 is asked for deviateing from basis displacement based on the displacement of the pedal 11 obtained from signal receiving part 21
Displacement, by the displacement deviateed from basis displacement and be set in advance in the threshold value th1 of record portion 22, threshold value th2 is compared
Compared with (S3).
First, whether operational part 23 judges the displacement from basis displacement deviation beyond threshold value th1 (S4).From benchmark
The displacement that displacement deviates without departing from threshold value th1 in the case of (S4 "No"), pedal 11 is judged to normally, returning by operational part 23
Return to step S2.
From the displacement that basis displacement deviates beyond threshold value th1 in the case of (S4 "Yes"), operational part 23 will be super
The step identification information for going out threshold value th1 step 6 recorded record portion 22 (S5).Next, operational part 23 is judged from benchmark position
The displacement deviateed is moved whether beyond threshold value th2 (S6).In the feelings from the displacement that basis displacement deviates beyond threshold value th2
Under condition (S6 "Yes"), operational part 23 is regarded as the possibility height of pedal 11 and the contact of broach 18 or the danger that step 6 comes off be present
Danger, so that the operating of apparatus of passenger conveyor 1 stops (S7).
From the displacement that basis displacement deviates without departing from threshold value th2 in the case of (S6 "No"), operational part 23 judges
For in the absence of pedal 11 and broach 18 contacts or pedal 11 comes off exception.Then, there will be inclined from basis displacement for operational part 23
From displacement becoming this case of big step 6 and be used as omen, by alarm and be recorded in the step identification letter of record portion 22
Breath is sent (S8) to monitoring unit 10 together.Operational part 23 have issued the stage of abnormal omen, continue apparatus of passenger conveyor 1
Operating.
In the apparatus of passenger conveyor 1 involved by the 1st embodiment example described above, the pecten of gateway is installed on
15a, 15b itself displacement detecting portion 16a, 16b often detect the position of the short transverse of the step 6 moved under horizontality
Move.At this moment, the broach 18 for being formed at the groove of pedal 11 and being installed on pecten 15a, 15b front end all engages, and is guided by broach 18
The groove of pedal 11, thus limit movement of the step 6 to width.Therefore, operational part 23 can be based on by displacement detecting sensor
The displacement of 17 pedals 11 detected exactly the short transverse of computing pedal 11 from basis displacement deviate displacement.Separately
Outside, in upper horizontal section 9A and lower horizontal section 9B, because the movement of the short transverse of step 6 is lacked, therefore displacement detecting passes
Sensor 17 is easy to only detect the displacement of the pedal 11 of short transverse.
Also, in the case of from the displacement that basis displacement deviates beyond threshold value th1, operational part 23 is to monitoring unit 10
Alarm is sent, in the case of from the displacement that basis displacement deviates beyond threshold value th2, operational part 23 stops rapidly passenger's biography
Send equipment 1.Accordingly, it is capable to prevent the damage of broach 18, pecten 15a, 15b because caused by being in contact there occurs the pedal 11 of exception
Wound.
In addition, displacement detecting sensor 17 is pre-set at detection components 14, detection components are installed in pecten leading section 13
14 operation is easy to.Accordingly, it is capable to reduce the labour in pecten 15a, 15b installation displacement detecting sensor 17 and time, moreover it is possible to
Reduce setup cost.
It can be determined further, since there occurs the pedal 11 of exception by step identification information, therefore operating personnel can be only
Pedal 11 determined by replacing.It therefore, there is no need to change step 6, replacement operation facilitation can be made.

Carry out adjustment and the breakdown judge of displacement detecting sensor 17.In figure, displacement detecting sensor 17 is abbreviated as " sensing
Device ".In addition, in the processing shown in Fig. 8, main explanation uses the displacement detecting portion 16a's for being arranged at upside discrepancy floor 3a
Example, on then being omitted using the example for the displacement detecting portion 16b for being arranged at downside discrepancy floor 3b for carrying out same action
Explanation.
First, control unit 7 judges whether apparatus of passenger conveyor 1 is in operating (S11).It is not fortune in apparatus of passenger conveyor 1
In the case of in turning (S11 "No"), control unit 7 continues step S1 processing.Situation in apparatus of passenger conveyor 1 is operating
Under (S11 "Yes"), operational part 23 carry out displacement detecting sensor 17 outgoing inspection (S12).Displacement detecting sensor 17
Whether outgoing inspection is to judge in advance in the sensor output signal of each displacement detecting sensor 17 output comprising different
Constant value and carry out.
Therefore, in the outgoing inspection of displacement detecting sensor 17, by the displacement record of the pedal 11 of the amount of a circle to note
In record portion 22, operational part 23 is by the displacement of the pedal 11 of the amount of a circle and is pre-set in the normal value of record portion 22 and is compared

(S18).Then, operational part 23 asks for the displacement deviateed from basis displacement based on the displacement of pedal 11, will be from basis displacement
The displacement of deviation and be pre-set in the threshold value th1 of record portion 22, threshold value th2 is compared (S19).
Next, whether operational part 23 judges the displacement from basis displacement deviation beyond threshold value th1 (S20).From
The displacement that basis displacement deviates without departing from threshold value th1 in the case of (S20 "No"), operational part 23 be regarded as pedal 11 it is normal and
Return to step S18.From the displacement that basis displacement deviates beyond threshold value th1 in the case of (S20 "Yes"), operational part
23 are recorded in the identification information of the step 6 beyond threshold value th1 in record portion 22 (S21).
Next, whether operational part 23 judges the displacement from basis displacement deviation beyond threshold value th2 (S22).From
The displacement that basis displacement deviates beyond threshold value th2 in the case of (S22 "Yes"), operational part 23 is regarded as the He of pedal 11 being present
The danger that broach 18 contacts or step 6 comes off, so that the operating of apparatus of passenger conveyor 1 stops (S23).
From the displacement that basis displacement deviates without departing from threshold value th2 in the case of (S22 "No"), operational part 23 judges
For the exception for pedal 11 not occurring and broach 18 contacts or step 6 comes off.Then, there will be there occurs big displacement for operational part 23
This case of pedal 11 be used as omen, alarm is sent out together with the step identification information for being recorded in record portion 22 to monitoring unit 10
