[0026]
As shown in FIGS. 4 and 5, the display unit 13 has a predetermined range at a predetermined height position on the inner wall surface of the entry / exit room 30, and includes a “touch surface for emergency stop” therein. is there. The displayed panel may be stuck on the wall without directly writing on the wall. This display is a display for urging a person in the entry / exit room 30 to touch that part in an emergency, and is not limited to the above wording. In short, any display that is easy for human eyes, attention, and easy to understand may be used. For this purpose, it is preferable to display large characters using color paint of a conspicuous color (red, yellow, etc.). The display unit 13 is formed such that the lower end thereof is at a relatively low position (for example, a height of 50 cm from the floor) so that a user of a wheelchair or a person who has fallen on the floor can touch the display unit 13 in that state. The upper and lower widths are wide (for example, 50 cm wide) so as to be easily touched. The length in the lateral direction depends on the size of the wall surface of the loading / unloading room, but it is preferable to make the length as long as possible because it is easy to touch. In the present embodiment, the display units 13 are formed on the left and right side walls, the rear wall surface excluding the mirror 37, and the wall surfaces on both sides of the front door 32. Of course, a display unit may be formed on the mirror 37.
[0027]
In this embodiment, a wide photoelectric sensor is used as the photoelectric sensor 12. This sensor comprises a pair of a plurality of light beam emitters 12a assembled in a line and a long light receiver 12b for detecting the light beam B. In the wide photoelectric sensor, as shown in FIG. 6, a large number of light beams B are distributed in parallel over the entire vertical width of the display unit 13, and are irradiated in the horizontal direction near the display unit. This state is also called a photoelectric screen. Both the light-emitting body 12a and the light-receiving body 12b of the photoelectric sensor 12 are attached to both ends of the inner wall surface, that is, at each corner of the entrance / exit room 30, so that the light beam B runs parallel to any wall surface, These are all detected. The vertical width and height of the photoelectric screen coincide with those of the display unit 13 as described above. Further, the photoelectric sensor 12 is preferably installed so that the light beam B is as close to the wall as possible within a range in which the light beam B is not blocked by irregularities on the wall. The detection beam emitted by the above-described detection beam emitter 12a includes not only visible light but also infrared light and laser.
[0028]
According to the safety device 11, when a person touches the display unit with a hand or the like, the hand or the like blocks the light beam B and detects the light beam B. In the control device 35, an alarm is issued from an alarm device 36 based on a detection signal from the photoelectric sensor 12, and a drive device (not shown) of the door 32 is operated in a direction in which the door is opened, and an operation of the transport device is performed. To stop. When the door 32 is open from the beginning or when the transport device is not yet operated, the control device 35 instructs the door 32 to be locked so that the closing operation of the door 32 and the operation of the transport device are not started.
[0029]
FIG. 7 shows an example of these operations as a flowchart. (1) First, when the light beam B for detection is blocked by a person's hand in the entry / exit room, (2) the alarm device 36 issues an alarm, and (3) if the transport device has already started moving, 4) Stop this. (5) If the door of the entry / exit room is closed, (6) open it. (7) Broadcast the exit guidance from the entry / exit room through the alarm device. (8) When it is confirmed by the position sensors 41 to 45 and the like that there is no person in the entry / exit room, (9) the alarm is stopped and (10) the door is closed. (11) Release the stop of the transport device. When the stop is released, the transport device can be operated by operating the operation operation panel as usual.
[0030]
This flow is an example. Therefore, the present invention is not limited to the above, and various procedures can be adopted.
[0031]
FIG. 8 shows an example of a sensor arrangement different from the photoelectric sensor 12 described above. The sensor 14 shown in FIG. 8A has a light-emitting body 14a and a light-receiving body 14b arranged on both left and right ends of a wall surface. One light-emitting body 14a and one light-receiving body 14b correspond to each other, and the detection light beams B cross each other. That is, the light beams need not be parallel light beams as shown in FIGS.
[0032]
Although the sensor 15 shown in FIG. 8B may be a wide sensor, the light emitter 15a is disposed on one side (left side) of the door 32, and the light receiver 15b is disposed on the other side (right side) of the door 32. Are located. Then, reflection mirrors 17 are arranged at the ends of the wall surfaces (corners of the entry and exit rooms). Each reflecting mirror 17 is mounted in such a direction that the reflected light of the light beam irradiated along the wall surface is also reflected along the wall surface. As a result, the light beam B travels around the indoor peripheral surface, so that a pair of sensors can form photoelectric screens on four wall surfaces in the indoor room.
[0033]
In the sensor 16 shown in FIG. 8C, one light emitter 16a corresponds to a plurality of light receivers 16b. Since the light beam B emitted from the light emitter 16a spreads the light at a certain angle, the spread detection light from one light emitter 16a is detected by the plurality of light receivers 16b using this. Things. Equipment costs can be reduced. A portion where light is spread may be used as a photoelectric screen, and the portion may be arranged so as to correspond exactly to the display unit 13.
[0034]
FIG. 8D shows a sensor obtained by combining the sensor 16 shown in FIG. 8C and a sensor in which the sensor 16 is arranged left and right. That is, one sensor 16 in which one light emitter 16a is arranged on the left end of the wall surface and a plurality of light receivers 16b are arranged on the right end, and one light emitter 16a is arranged on the right end, and a plurality of light receivers 16b are arranged on the left end. The other sensors 16 are combined so that their light beams B cross each other. Thereby, the distribution density of the light beam B is increased, so that the detection accuracy is improved.
[0035]
FIG. 9 shows another safety device 21. The safety device 21 includes a tape switch 22 attached to an inner wall of the storage room 30. When the tape switch 22 is pressed, the detector 24 detects by conduction. On the surface of the tape switch 22, "Emergency stop touch surface" is displayed so as to be conspicuous in the same manner as the display unit. The size of the tape switch 22 also has a vertical width of about 50 cm, and is affixed such that its lower end is at a height of about 50 cm from the floor surface. The length in the lateral direction depends on the size of the wall surface of the loading / unloading room, but it is preferable to make the length as long as possible because it is easy to touch. Reference numeral 22a is a terminal portion of the tape switch.
[0036]
As shown in the drawing, the tape switch 22 has two conductive tapes 23a and 23b separated from each other in the thickness direction of the tape switch, and a small current flows through each tape. When the tape switch 22 is pressed, the two tapes 23a and 23b come into contact and conduct. The tapes 23a and 23b may be cut. This conduction or disconnection is detected by the detector 24, and the control device 35 operates according to a detection signal from the detector 24.
[0037]
The safety device to be pressed is not limited to this tape switch. A known pressure-sensitive switch plate may be employed. In short, it is effective to provide a conspicuous display section with a sufficient area. Since it is provided on the wall surface, it is preferable because it is not obstructive and stands out.
[0038]
The safety device described above does not require the user to know what principle works. In any case, it is important that the safety device be easily operated even in a state where the user is upset and cannot judge calmly. For this purpose, a wall is provided with a conspicuous display section having a sufficient area.
[0039]

A sensor 44 is provided. When the sensors 43 and 44 determine that the front end or the rear end of the vehicle M that has entered the lift 4 is protruding from the lift 4, an alarm is issued from the alarm device 36 or the like, and the operation of the parking device 1 is stopped. . Fifth sensors 45 are installed at predetermined positions on both the left and right sides in the loading / unloading room 30 corresponding to a portion H slightly retreated from the front edge of the lift 4. The purpose of the fifth sensor 45 is to guide the vehicle so as to stop in an appropriate range on the pallet 2 in cooperation with the third sensor 43, and the vehicle M enters at least the portion H of the lift 4. It is to detect whether or not there is. As shown, the vehicle M is guided by a guide broadcast or the like to a position where the front end of the vehicle M is not detected by the third sensor 43 and detected by the fifth sensor 45. For example, when the sensor 45 is not shielded from light when entering the vehicle, it is guided to "a little more forward", and when the sensor 43 is shaded by going too far, it is guided to "back a little more". When the light is shaded, you will be informed, for example, "You have stopped at the correct position. Apply the side brake and get off."
