図２(a)において、第１踏み段１５は、側面視三角形状で、乗客Ｍか乗る第１踏み面部１５aと、第１踏み面部１５aと一体になると共に、乗った乗客Ｍの足の前方に位置する第１ライザ部１５rと、第１踏み面部１５aの端部と第１ライザ部１５rの端部とを連結する第１ブラケット部１５ｂとを備え、第１踏み面部１５aと第１ライザ部１５rと第１ブラケット部１５ｂとにより囲まれる三角形状の第１空洞部１５ｅを有している。 In FIG. 2 (a), the first step 15 has a triangular shape in a side view, and is integrated with the first tread surface portion 15a on which the passenger M rides and the first tread surface portion 15a. A first riser portion 15r, a first bracket portion 15b connecting the end portion of the first tread surface portion 15a and the end portion of the first riser portion 15r, and the first tread surface portion 15a and the first riser portion. It has a triangular first cavity 15e surrounded by 15r and the first bracket 15b.

第２踏み段２５は、第１踏み段１５の進行方向に対して一段遅れると共に、第１踏み段１５と同様に、側面視三角形状で、乗客Ｍか乗る第２踏み面部２５aと、第２踏み面部２５aと一体に形成された第２ライザ部２５rと、第２踏み面部２５aの他端部と第２ライザ部２５rの他端部とを連結する第２ブラケット部２５ｂとを備え、第２踏み面部２５aと第２ライザ部２５rと第２ブラケット部２５ｂとにより囲まれる三角形状の第２空洞部２５ｅを有している。

The third step 35 is delayed by one step with respect to the traveling direction of the second step 25, and, like the first step 15, the third step surface portion 35a, the third bracket portion 35b, and the third riser on which the passenger M rides. It has a part 35r.

図２(ａ)において、乗客コンベア１は、検出手段としての隙間検出器５０を有している。隙間検出器５０は、降り込み口９付近にて、各踏み段の高さが段々と低くなることにより第１踏み段１５と第２踏み段１５とにより形成される第１隙間２１の有無を検出するものである。
隙間検出器５０は、第１踏み段１５の第１ライザ部１５ｒと第２踏み段２５の第２踏み面部２５ａとの接触部の近傍に形成される鋭角状で三角柱状の第１隙間部２１を形成しており、第２ライザ部２５ｒと第３踏み面部３５ａとの接触部の近傍に形成される鋭角状で三角柱状の第２隙間部２２を形成しており、第１ライザ部１５ｒに沿う方向に対して(図２の上から下へ)の第１隙間部２１の投影面積Ｓ１、第２ライザ部２５ｒに沿う方向に対して(図２の紙面の上から下へ)の第２隙間部２２の投影面積Ｓ２とするとＳ１＜Ｓ２となる第１隙間部２１を検出すると共に、前回の第１隙間部２１よりも今回の第１隙間部２１の投影面積Ｓ１が狭くなったことを検出する隙間検出器５０を備えたものである。
ここで、第１隙間部２１の投影面積Ｓ１が第２隙間部２２の投影面積Ｓ２よりも少なくなる位置において、第１隙間部２１の投影面積Ｓ１を検出するのは、降り込み口９に近づくにつれて該投影面積が狭くなり乗客Ｍの靴などが挟まれやすくなること未然に防止するためである。 In FIG. 2A, the passenger conveyor 1 has a gap detector 50 as detection means. The gap detector 50 detects the presence or absence of the first gap 21 formed by the first step 15 and the second step 15 by gradually decreasing the height of each step near the entrance 9. It is to detect.
The gap detector 50 is an acute-angled triangular prism-shaped first gap portion 21 formed in the vicinity of a contact portion between the first riser portion 15r of the first step 15 and the second tread surface portion 25a of the second step 25. The second gap portion 22 is formed in the vicinity of the contact portion between the second riser portion 25r and the third tread surface portion 35a and is formed in the acute-angled triangular prism-like second gap portion 22, and the first riser portion 15r The projected area S1 of the first gap 21 with respect to the direction along (from top to bottom in FIG. 2), the second with respect to the direction along the second riser portion 25r (from top to bottom in FIG. 2). When the projected area S2 of the gap 22 is detected, the first gap 21 that satisfies S1 <S2 is detected, and that the current projected area S1 of the first gap 21 is smaller than the previous first gap 21. A gap detector 50 for detection is provided.
Here, in the position where the projected area S1 of the first gap portion 21 is smaller than the projected area S2 of the second gap portion 22, the projected area S1 of the first gap portion 21 is detected close to the entrance 9. This is to prevent the projected area from becoming narrow and the shoes of the passenger M from being easily caught.

別言すれば、図２(ａ)において、隙間検出器５０は、踏み段部５の第１踏み段１５の第１踏み面部１５ａの第１延長線Ｌ1と、第１踏み段１５の一つ下方の第２踏み段２５の第２踏み面部２５ａの第２延長線Ｌ2とを垂直方向の第１高さをｈ1とし、降り込み口９付近の近傍で、第２踏み段２５の一つ下方の第３踏み段３５の第２延長線Ｌ２と第３延長線Ｌ３とを結ぶ垂直方向の第２高さをｈ2として、ｈ1＜ｈ2となる第１踏み段１５の第１ライザ部１５ｒと第２踏み段２５の第２踏み段面部２５ａとの接触部の近傍に形成される鋭角状で三角柱状の第１隙間部２１の有無を検出する第１隙間部Ｓ１を検出すると共に、前回の第１隙間部２１よりも今回の第１隙間部２１の投影面積Ｓ１が狭くなったことを検出する隙間検出器５０を備えたものである。
ここで、踏み段の高さが異なる位置の第１隙間部２１を検出するのは、降り込み口９に近づくにつれて該第１隙間部２１が狭くなり乗客Ｍの靴などが挟まれやすくなることを未然に防止するためである。 In other words, in FIG. 2A, the gap detector 50 includes one of the first extension line L 1 of the first step surface 15 a of the first step 15 of the step portion 5 and one of the first step 15. The second height L2 of the second step surface 25a of the lower second step 25 and the first height in the vertical direction is h1, and one second below the second step 25 in the vicinity of the entrance 9 The second riser portion 15r of the first step 15 and the second height 15h of the first step 15 satisfying h1 <h2, where h2 is the second height in the vertical direction connecting the second extension line L2 and the third extension line L3 of the third step 35. In addition to detecting the first gap S1 that detects the presence or absence of the acute-angled triangular prism-shaped first gap 21 formed in the vicinity of the contact portion of the two-step 25 with the second step surface 25a, A gap detector 50 that detects that the projected area S1 of the first gap 21 is narrower than the one gap 21 is provided. .
Here, the reason for detecting the first gap portion 21 at a position where the step height is different is that the first gap portion 21 becomes narrower and the shoes of the passenger M and the like are easily pinched as approaching the entrance 9. This is in order to prevent this.

光検出器３０は、上記のように踏み段の高さが変化する位置の第１隙間部２１に沿って(図２の紙面の上から下へ)光ビーム３０ｂを照射する照射部３０ａと、該光ビーム３０ｂを受光すると共に、受光することによりパルス信号を発生する受光部３０ｃとを有している。この光ビーム３０ｂが照射されると、第１隙間部２１の(照射部３０aからの光ビーム３０ａを照射する)位置に到達した時に、正常時に受光部３０ｃから図２(ｂ)に示すように、第１空洞部１５ｅ、第１隙間部２１、第２空洞部２５ｅにそれぞれ対応するパルスＰｎ１，Ｐｅ，Ｐｎ２が発生する。これに対して、異常時に受光部３０ｃから図２(ｃ)に示すように、乗客Ｍの靴などで、第１隙間部２１が形成されなくなるので、第１空洞部１５ｅ、第２空洞部２５ｅにそれぞれ対応するパルスＰｎ１，Ｐｎ２が連続して発生するように形成されている。ここで、パルスＰｎ1とパルスＰｎ２とのオン時間は、等しく、パルスＰｅのオン時間は、パルスＰｎ1の１／５である。
ここで、上記投影面積を検出するのに、投影面積は、略正三角形であるので、該正三角形内の上記光ビーム３０aの通過時間を基礎にして広狭を判断するためである。
また、第１隙間部２１についても、第１隙間部２１内を上記光ビーム３０aの通過時間を基礎にして広狭を判断するためである。 The light detector 30 irradiates the light beam 30b along the first gap portion 21 at the position where the step height changes as described above (from the top to the bottom of FIG. 2), The light receiving unit 30c receives the light beam 30b and generates a pulse signal by receiving the light beam 30b. When the light beam 30b is irradiated, when it reaches the position of the first gap portion 21 (irradiates the light beam 30a from the irradiation unit 30a), the light receiving unit 30c in a normal state as shown in FIG. The pulses Pn1, Pe, Pn2 corresponding to the first cavity 15e, the first gap 21, and the second cavity 25e are generated. On the other hand, as shown in FIG. 2 (c) from the light receiving portion 30c at the time of abnormality, the first gap portion 21 is not formed with the shoes of the passenger M or the like, so the first cavity portion 15e and the second cavity portion 25e. Are formed so that pulses Pn1 and Pn2 respectively corresponding to. Here, the ON times of the pulses Pn1 and Pn2 are equal, and the ON time of the pulse Pe is 1/5 of the pulse Pn1.
Here, the projected area is detected because the projected area is a substantially equilateral triangle, and therefore, the width is determined based on the transit time of the light beam 30a in the equilateral triangle.
Further, the first gap 21 is also determined to be wide or narrow in the first gap 21 based on the passage time of the light beam 30a.

隙間検出器５０は、このパルスＰｎ，Ｐｅのオン時間をパルスの立ち上がりと、立下りから求めてメモリ５２ａに記憶するオン時間検出部５２と、前回と今回とのオン時間とを比較する判断手段としての比較部５４とを備えており、比較部５４は、異常時には前回と今回とのオン時間がほぼ同一となるので、前回と今回のオン時間の比が０．８〜１．２ならば、異常と判断して異常信号を発生し、前回と今回とのオン時間との比が上記０．８〜１．２の範囲外であれば、正常と判断するように形成されている。 The gap detector 50 obtains the ON times of the pulses Pn and Pe from the rising and falling edges of the pulses and stores them in the memory 52a, and a determination means for comparing the previous and current ON times. The comparison unit 54 is configured so that when the abnormality is abnormal, the previous and current on-times are substantially the same, so that the ratio of the previous and current on-time is 0.8 to 1.2. If the ratio between the previous time and the current on time is outside the range of 0.8 to 1.2, it is determined to be normal.

上記のように構成された乗客コンベアの制御装置の動作を図１から図３を参照して説明する。
＜正常時＞
いま、図１に示すように、乗客コンベア１の降り込み口９付近にて、各踏み段の高さが段々と低くなることにより第１踏み段１５と第２踏み段１５とにより形成される第１隙間部２１に乗客Ｍの靴などが存在しないとすると、光検出器３０の受光部３０ｃから図２(ｂ)に示すように、第１空洞部１５ｅ、第１隙間部２１、第２空洞部２５ｅにそれぞれ対応するパルスＰｎ１，Ｐｅ，Ｐｎ２が順に発生する。隙間検出器５０のオン時間検出部５２ａは、パルスＰｎ1の立上りと立下りとからオン時間ｔａを求めてメモリ５２ａに記憶し，同様にしてパルスＰｅのオン時間ｔｂを求めてメモリ５２ａに記憶する。
比較部５４は、前回のパルスのオン時間ｔａと今回のパルスのオン時間ｔｂとの比を求めると、１／５となり、基準範囲(０．８〜１．２)内か否かを判断し、範囲外であるので、正常と判断する。これにより、乗客コンベア１の運転を継続する。 The operation of the control device for a passenger conveyor configured as described above will be described with reference to FIGS.
<Normal>
Now, as shown in FIG. 1, the height of each step is gradually reduced near the entrance 9 of the passenger conveyor 1, thereby forming the first step 15 and the second step 15. Assuming that there is no passenger M's shoes in the first gap 21, the first cavity 15 e, the first gap 21, the second from the light receiving part 30 c of the photodetector 30, as shown in FIG. Pulses Pn1, Pe, and Pn2 respectively corresponding to the cavity 25e are sequentially generated. The on-time detector 52a of the gap detector 50 obtains the on-time ta from the rise and fall of the pulse Pn1, stores it in the memory 52a, and similarly obtains the on-time tb of the pulse Pe and stores it in the memory 52a. .
When the ratio between the on time ta of the previous pulse and the on time tb of the current pulse is obtained, the comparison unit 54 determines that the ratio is 1/5 and is within the reference range (0.8 to 1.2). Because it is out of range, it is determined to be normal. Thereby, the operation of the passenger conveyor 1 is continued.

＜異常時＞
次に、乗客コンベア１の降り込み口９付近にて、各踏み段の高さが段々と低くなることにより第１踏み段１５と第２踏み段１５とにより形成される第１隙間部２１に乗客Ｍの靴などが存在しすると、光検出器３０の受光部３０ｃから図２(ｃ)に示すように、第１空洞部１５ｅ、第２空洞部２５ｅにそれぞれ対応するパルスＰｎ１，Ｐｎ２が発生する。ここで、第１隙間部２１には、乗客Ｍの靴が存在するので、パルスＰｅが発生しない。
隙間検出器５０は、時間ｔ1でパルスＰｎ1のオン時間ｔａを求めてメモリ５２ａに記憶し，時間ｔ5で、パルスＰｎ２のオン時間ｔｂを求めてメモリ５２ａに記憶する。
比較部５４は、前回のパルスのオン時間ｔａと今回のパルスのオン時間ｔｃとの比を求め、基準範囲(０．８〜１．２)内か否かを判断する。オン時間ｔａとオン時間ｔｃの比は１となり、基準範囲外であるので、異常と判断して異常信号を発生して制御部６０に入力する。制御部６０は、乗客コンベア１の運転を停止すると共に、スピーカ７０により警告を乗客Ｍに発する。 <In case of abnormality>
Next, in the vicinity of the entrance 9 of the passenger conveyor 1, the height of each step is gradually lowered, so that the first gap portion 21 formed by the first step 15 and the second step 15 is formed. When there is a shoe of the passenger M, pulses Pn1 and Pn2 corresponding to the first cavity portion 15e and the second cavity portion 25e are generated from the light receiving portion 30c of the photodetector 30 as shown in FIG. To do. Here, since the shoes of the passenger M exist in the first gap portion 21, the pulse Pe is not generated.
The gap detector 50 obtains the ON time ta of the pulse Pn1 at time t1 and stores it in the memory 52a, and obtains the ON time tb of the pulse Pn2 at time t5 and stores it in the memory 52a.
The comparison unit 54 obtains the ratio between the on time ta of the previous pulse and the on time tc of the current pulse, and determines whether it is within the reference range (0.8 to 1.2). The ratio between the on time ta and the on time tc is 1, which is out of the reference range, so that it is determined as abnormal and an abnormal signal is generated and input to the control unit 60. The control unit 60 stops the operation of the passenger conveyor 1 and issues a warning to the passenger M through the speaker 70.
