Definitions

• the present invention relates to all the solid-state devices having a photoelectric sensor device for detecting foreign matter contained therein.
• It is equipped with a photoelectric sensor device that detects foreign matter contained in the product and a battery device that controls the rotation of the car according to the sensor device.
• At least immediately after the start of the It is set to be. It shows the whole device of the door of the solid by 0007 of the description. It shows the state where the object is sandwiched between the two doors. 3 2 shows the state immediately after the descent has started descending.
• 6 5 shows the state immediately after starting the ascending movement.
• the doorway is opened and closed by two doors 23.
• the door 2 is equipped with an optical device 4 that emits a plurality of light beams (indicated by marks) at equal intervals in the vertical direction.
• the optical device 4 is arranged along the downward length of the door 2.
• the sensor 6 has a light projector 45, and detects the foreign matter trapped by the door 23 by cutting off the detection light.
• the door 7 controls the light projector 4 and determines whether there is any foreign matter between the doors 2 and 3 based on the items 5 and the like. Further, the door 7 has a lamp and is mounted on, for example, the top.
• the 001 door 7 is set so that the foreign substance function of the photoelectric sensor 6 is effective during the operation, at the time of all the doors, and at the time of traveling. It is also effective immediately after the start of a foreign matter caused by the photoelectric sensor 6.
• the door 7 issues a reversal instruction without opening the door. (If the photoelectric sensor 6 detects foreign matter immediately after the start of operation, operation 8 Please stop and return the stop you just left.
• 001 42 indicates a state in which is between the doors 23 of the door.
• the optical device 4 is provided with a plurality of door sensor elements which are vertically equidistant from each other (for example, between 4 and 5).
• 5 has a plurality of doors (doors) that are the corresponding door sensor elements facing each other.
• Reference numeral 01744 is a door chart showing the door work, foreign matter function, and work when the door is sandwiched between the doors 23.
• the foreign matter remains effective even after the entire condition has been reached.
• the car starts running in this state, and when is detected at time 2, the car is stopped. During this time, the rice will be returned to its place between 3 and 4. Then, at time 4, the station was stopped and .
• the foreign matter function of the photoelectric sensor device is effective immediately after the start of the car. By doing so, foreign matter can be detected when is displaced within the area of the photoelectric sensor 6.
• Fig. 6 shows the state immediately after the car in 5 starts ascending.
• the door 2 has a light emission 5 as a door sensor element.
• a door sensor element (z) facing the light emission 5.
• the optical device 4 similar to that of the implementation, it also has five light emitting elements.
• the plate and the child are vertically spaced. Although it is placed, you may place it at different intervals depending on the placement. For example, in the part of, it may be evenly spaced, and in the upper part, the degree of arrangement may be II than in the lower part.
• central type door arrangement is shown in the above example, it is also applicable to this type of door arrangement.
• an anomaly detection signal may be issued as a function of the foreign matter beta. Always detected, eg sent to the beta room. This allows maintenance to be performed on-site to remove foreign matter and check for abnormalities. Also, depending on the anomaly detection signal, an announcement may be broadcast to the passenger or passenger to request removal of foreign matter.
• foreign matter from the photoelectric sensor device if it is valid at least during operation and immediately after the start of the car, for example, may be invalidated after a predetermined time from the start, or may be invalidated after a predetermined time after placement.
