FIG. 7 is a front view and a side view showing essential parts of a toilet door opening/closing switch according to a third embodiment of the present invention. It is a front view and a side view of a conventional toilet door opening/closing switch.

An outline of an embodiment of an automatic toilet door system of the present invention will be explained with reference to FIGS. 1 and 2.
(Example 1)
The toilet 21 has a sliding door 22 arranged in an opening 21a so as to be openable and closable, and a motor, a door position detection unit such as an encoder (not shown), a power transmission mechanism such as a timing belt, etc., are installed in the upper part of the opening 21a. A drive controller 24 is provided that drives the drive operation of the drive device 23 using an appropriate output signal. An electric lock 25 is connected to the drive controller 24 via an electric lock controller 26, and locks or unlocks the door 22 in a timely manner in response to the opening/closing operation of the door 22.
In addition, a toilet bowl 21b and a wash basin 21c are installed in the toilet 21, and an emergency call switch 34 is provided near the toilet bowl 21b, and other equipment such as an interior light and a ventilation fan (not shown) are installed as appropriate. It is.

Further, an outdoor toilet door opening/closing switch 1 is disposed on the outside of the toilet 21, and an indoor toilet door opening/closing switch 2 is disposed on the indoor side. The toilet outdoor door opening/closing switch 1 and the toilet indoor door opening/closing switch 2 have approximately the same appearance and are collectively referred to as toilet door opening/closing switches, and each has an opening push button part 3, a closing push button part 4, and a state. A display section 5 is provided.

The outdoor toilet door opening/closing switch 1 and the toilet indoor door opening/closing switch 2 are connected to the drive controller 24 via an operation guide controller 27 that controls their operations, and are linked to the opening/closing operation of the door 22. . That is, the door 22 is activated when an open signal or a close signal is transmitted by pressing the opening push button part 3 and the closing push button part 4 of the toilet outdoor door opening/closing switch 1 and the toilet indoor door opening/closing switch 2. The drive controller 24 controls the drive device 23 to open and close the door 22.

Further, the opening push button section 3 and the closing push button section 4 may be general push buttons, but a light emitting section is formed on each of them, and the light emitting sections are activated continuously or intermittently under the control of the operation guide controller 27. It has an operation assist function that lights up the button and indicates to the user which button to press next.
Although the push button portions of the toilet outdoor door open/close switch 1 and the toilet indoor door open/close switch 2 may be arranged horizontally as shown in FIG. 1, it is preferable to arrange them vertically as shown in FIG.

As shown in FIG. 2, the voice guidance device 28 includes a speaker 29, a storage section (ROM) 30 in which a desired guidance message is recorded in advance and registered as a file, and a predetermined message is appropriately selected from the storage section 30. and an audio controller 31 that outputs the audio to the speaker 29. The audio controller 31 is connected to an operation guide controller 27 that controls the light emission of the opening push button section 3 and the closing push button section 4, and controls the push buttons of the toilet outdoor door opening/closing switch 1 and the toilet indoor door opening/closing switch 2. A guidance message is made to be uttered from a speaker 29 to the user in conjunction with the operation of the section.

Furthermore, an outdoor proximity sensor 32 for non-contact detection of the user is installed inside or around the toilet outdoor door opening/closing switch 1 outside the toilet 21, and the proximity sensor 32 is connected to the operation guide controller 27. The audio controller 31 is connected to the audio controller 31 via the audio controller 31. Thereby, when the proximity sensor 32 detects a user approaching the toilet outdoor door opening/closing switch 1, the audio controller 31 causes the speaker 29 to output a predetermined audio message.
The proximity sensor 32 may be a capacitance type sensor or the like, but it may also be an optical sensor for activation that is used in normal automatic doors and can detect the position of a passerby by subdividing the detection area. This makes it possible to distinguish between when a passerby approaches the door 22 and when the passerby approaches the toilet outdoor door opening/closing switch 1, so that a more optimal voice message can be uttered.
Further, an indoor proximity sensor 33 that detects a user in a non-contact manner may be placed inside or around the toilet door opening/closing switch 2 inside the toilet 21 as well. This allows users in the restroom to speak their voice messages at more optimal timing.

As for the speakers, one speaker 29a and one speaker 29b may be arranged inside or near the toilet outdoor door opening/closing switch 1 and the toilet indoor door opening/closing switch 2 as shown in FIG. A speaker 29 may be installed inside the toilet so that the guidance message can be heard both inside and outside the toilet room 1.
In addition, the storage unit 30 stores guidance messages corresponding to the opening/closing status of the door 22, the operation status of the push buttons of the toilet door opening/closing switches 1 and 2, the purpose of guidance, etc., recorded in advance for each type of voice in multiple languages and registered as files. It is something that

Guidance messages are registered in the storage unit 30 in multiple languages according to the situation, and the voice controller 31 cooperates with the operation guidance controller 27 to display the open/close status of the door 22, the push button parts of the toilet door open/close switches 1 and 2, and the emergency call switch 33. A guidance message corresponding to the operation status, the detection status of the proximity sensors 32 and 33, etc. is selected from the storage unit 30, and the selected guidance message is made to be uttered from the speaker 29.

Next, the structure of the push button portion of the toilet door opening/closing switches 1 and 2 of the present invention will be explained with reference to FIG. 3, taking the toilet outdoor door opening/closing switch 1 as an example. The toilet indoor door opening/closing switch 2 has a similar structure, and when both are collectively referred to as a toilet door opening/closing switch.
In FIG. 3(a), an opening push button section 3 and a closing push button section 4 are arranged with the status display section 5 in between. Further, a thin frame part 11 is arranged around the entire outer periphery of the toilet room door open/close switch, and the double push button parts 3 and 4, which move up and down along the frame part 11, are arranged to protrude beyond the frame part 11. Therefore, substantially the entire surface of both push button parts 3 and 4 is a push part that can be operated, and the structure is such that even a person with a physical disability can easily operate the push button parts 3 and 4.

An opening tactile symbol 8 is located near the center of the pressing part of the opening push button part 3, and a closing tactile symbol 9 is located near the center of the pressing part of the closing push button part 4. is formed to protrude from the surrounding surface. The tactile symbol allows even visually impaired people who cannot read Braille to identify whether the push button they touched is for opening or closing by touching it with their fingertips. In Figure 3(a), two equal sides of an isosceles triangle imitating the shape of an arrowhead at the end point of an arrow are combined and opposed in different directions to form different tactile symbols for opening and closing. There is. This tactile symbol has a small number of strokes and a simple shape, making it easy to identify and easy to intuitively understand even for those who touch it for the first time. However, the shape of the tactile symbol used to identify opening and closing is not limited to this; for example, two whole arrows with shafts may be combined, or two tactile symbols used to open and close elevator doors may be combined. A tactile symbol consisting of isosceles triangles or the like may be used, but the shape is more complex than the above example and difficult to recognize unless you are used to it.

In addition to the tactile symbols 8 and 9, a Braille portion 7 is formed on the pressing portions of the double push button portions 3 and 4 to protrude from the surrounding surface. In order to avoid confusion for visually impaired people, the Braille section 7 is preferably positioned away from both tactile symbols 8 and 9. At least the Braille part should be placed outside the rectangle circumscribing the tactile symbol, and it is even better to place it at a position 10 mm or more away from the rectangle circumscribing the tactile symbol. This can prevent confusion, including misrecognition by visually impaired people.
In the present invention, both the tactile symbols 8 and 9 and the Braille portion 7 are arranged at the pressing portions of the two push button portions 3 and 4, so that when the user touches the tactile symbol or the Braille portion, the push button is pressed. When the operator recognizes the push button part to be operated, it is possible to directly press the tactile symbol or Braille part, making it easy for visually impaired people to use. Conventionally, there have been no cases in which both a tactile symbol and a Braille part are provided on a push part.For example, if the Braille part is placed outside the push part of a pushbutton part, the user can easily use the Braille part. After the push button section is recognized as the push button section that the user wants to operate, it is necessary to search for the pressing section of the push button section again, and this cannot be said to be user-friendly for visually impaired people.

Base surfaces 3B and 4B of the pressing portions of both push button portions 3 and 4 may be flat or curved. The base surfaces 3B and 4B of the pressing portion are surfaces from which the Braille portion 7, both tactile symbols 8 and 9, etc. protrude. FIG. 3(b) is a sectional view taken along line AA when the base surface 3B of the pressing part of the opening push button part 3 is flat, and FIG. FIG. 3 is a cross-sectional view taken along line AA, showing an example of a curved surface that improves operability and design. In both cases, the tactile symbol 8 is formed to protrude from the base surface 3B of the pressing portion, which is a peripheral surface. In the example of FIG. 3(b), the display surface of the status display section 5 is made flat to match the base surfaces of the pressing parts of the double-push button parts 3 and 4, and in the example of FIG. 3(c), the display surface of the double-push button part 3 is flat. , 4 may be a convex curved surface to match the base surface of the pressing portion. This improves the design. Further, the base surfaces of the pressing portions of the double push button portions 3 and 4 and the display surface of the status display portion 5 may form approximately one surface as a whole. This further improves the design.

Further, a relatively large guide portion 10 is formed in the pressing portions of the opening push button portion 3 and the closing push button portion 4, and protrudes circumferentially from the surrounding surface. The guide part 10 has a diameter that is at least half or more of the smaller vertical and horizontal widths of the pressing parts of both push button parts 3 and 4, and has a diameter of at least half of the smaller vertical and horizontal widths of the pressing parts of both push button parts 3 and 4. formed around.
When the base surfaces of the pressing parts of the double-push button parts 3 and 4 and the display surface of the status display part 5 form one surface as a whole, the design is improved when viewed by a healthy person. Since there is no step between the pressing parts of the double-push button parts 3 and 4 and the display surface of the status display part 5, it is difficult for visually impaired people to know where the double-push button parts 3 and 4 are on the toilet door switch. It was not easy to judge by touch. On the other hand, by arranging the convex guide section 10 on the pressing section, the guide section 10 on the pressing section of both push button sections 3 and 4 can protrude high with respect to the display surface of the status display section 5. Therefore, even a visually impaired person can recognize the guide part 10 as a protruding part by tactile sense, and furthermore, if the protruding guide part 10 or the area surrounded by the guide part 10 has double push button parts 3 and 4, It becomes relatively easy to recognize. Since the guide portion 10 is located on the pressing portions of both the push button portions 3 and 4, it goes without saying that the push button portions 3 and 4 can be operated by pressing the guide portion 10 or the inside thereof.

Further, by providing the guide section 10, there is an effect that the visually impaired person is reminded of the existence of the tactile symbols 8, 9, and is also made aware of the positions of the tactile symbols 8, 9. That is, when recognizing the guide part 10 protruding on the pressing parts of the double push button parts 3 and 4 with a sense of touch, there is a high possibility that the user will also touch the tactile symbols 8 and 9 formed to protrude inside the guide part 10. It is from.
In FIG. 3, the guide portion 10 is projected in a circumferential shape, but the shape is not limited to this, and the pressing portion of the push button portion on which the guide portion 10 is formed may have an elliptical shape, an ellipse shape, a rounded square shape, etc. or the shape of the tactile symbol surrounded by the guide part 10. However, it is preferable that the guide part 10 has a continuous shape without any bends so that the guide part 10 itself is not recognized as a tactile symbol.
In addition, on the inner side of the guide part 10 where there are no protrusions of the tactile symbols 8 and 9, there is a dot texture in which convex points lower than the protrusions of the tactile symbols are repeatedly arranged vertically and horizontally, and points that are lower than the protrusions of the tactile symbols are placed repeatedly. A texture 12 such as a line texture in which low convex lines are repeatedly arranged in parallel may be arranged. The size, height, and spacing of the points constituting the texture 12 and the thickness and height of the lines are preferably such that when the texture 12 is touched with a fingertip, the fingertip touches the bottom surface. This may make it easier to recognize the presence and shape of the tactile symbol.

In addition, the opening push button section 3 and the closing push button section 4 emit light that is emitted by transmitting light from the LED, etc., when an LED (not shown) disposed on the back side of the push section emits light. A section 6 is provided. The light emitting section 6 is arranged here in a combination of two isosceles triangles so as to face each other in different directions so that when it emits light, it is easy to visually identify whether it is open or closed. In FIGS. 3(b) and 3(c), a circuit board on which an LED is mounted, a switch that is turned on and off by operating the push button part, a return spring for the push button part, etc. are arranged on the back side of the push button part 3. However, all illustrations are omitted. Further, FIG. 3 schematically shows the configuration of a light emitting part 6 that transmits light and a non-light emitting part that does not transmit light, and the configuration is not limited as long as these functions can be realized. For example, the entire body may be made of a light-transmitting resin, and only the non-light-emitting part may be painted or printed to prevent light from passing through. Alternatively, the non-light-emitting part may be made of a non-light-transmitting resin, and the light-emitting part may be made of a light-transmitting part. resin may be attached.

In this way, if the opening push button section 3 and the closing push button section 4 are provided with light emitting sections 6 of different shapes, and if only the light emitting section 6 of the push button section that can be operated depending on the situation emits light, it is possible to visually and intuitively Since the shape of the light emitting section 6 is displayed with high contrast so that it can be easily distinguished between open and closed positions, even people with low vision (socially visually impaired) can operate it relatively easily.
Moreover, the tactile symbols 8 and 9 on both push button parts 3 and 4 are formed to protrude above the light emitting part 6 so that the whole is included in the light emitting part 6, and the tactile symbols 8 and 9 are also formed from LEDs etc. It is a part of the light emitting section 6 that transmits light and emits light. Although it is not necessary for the tactile symbols to emit light as a function, both the tactile symbols 8 and 9 and the light emitting part 6 are arranged in the center of the push button parts 3 and 4, and each has a different shape. This is for identifying whether the button part is for opening or closing, and since it needs to be at least a certain size larger, the buttons may be arranged so as to overlap depending on the situation. The tactile symbols 8 and 9 and the light emitting part 6 may have the same shape and size, but the shapes of the tactile symbols 8 and 9 that are easy to identify by touch and the two light emitting parts 6 that are easy to identify visually The shapes do not necessarily match, and it is often preferable for the light emitting section 6 to have a larger area. Therefore, it is preferable that all of the tactile symbols 8 and 9 be included in the light emitting section 6, or that at least a part of the tactile symbols 8 and 9 be included in the light emitting section 6.

Next, the sizes and shapes of the tactile symbols 8 and 9 will be explained using the opening tactile symbol 8 as an example with reference to FIG. 4, but the closing tactile symbol 9 may be considered in the same manner. When the size of the tactile symbol is represented by a circumscribed rectangle as shown in FIG. 4(a), the length D of the long side of the rectangle is preferably 10 mm or more and 60 mm or less. More preferably, the length is 15 mm or more and 60 mm or less. Further, the short side length C is preferably 10 mm or more, and it is even better if it can be 15 mm or more. If the length D of the long side exceeds 60 mm, it will be difficult to recognize the entire tactile symbol, but within the above range, making the tactile symbol larger will make it easier for people with less tactile experience to tact. There are many. Further, the length of the straight line constituting the tactile symbol is preferably 5 mm or more; if it is shorter than this, it becomes difficult to recognize it as a line. Further, the guide part 10 is formed to surround the tactile symbol 8, but at the part closest to the tactile symbol 8, there is a distance of at least 1 mm or more between the upper surface of the guide part 10 and the upper surface of the tactile symbol 8. It is preferable to leave a gap of 2 mm or more.

FIG. 4(b) is a BB sectional view, and the height Ha of the tactile symbol 8 from the surrounding surface is 0.3 mm or more and 1.5 mm or less, more preferably 0.5 mm or more and 1.3 mm or less. It is good to do this. Further, the width Wa of the upper tactile portion of the tactile symbol 8 is preferably 0.5 mm or more and 1.5 mm or less, more preferably 0.5 mm or more and 1.3 mm or less. The cross-sectional shape may be rectangular, trapezoidal, etc., but is not limited to this, as long as the height from the surrounding surface and the width at the top fall within the above range. Further, even when the surrounding surface is not a flat surface but a curved surface, the height from the curved surface only needs to be within the above range.
Similarly, the height Hb of the guide portion 10 from the surrounding surface is preferably 0.3 mm or more and 1.5 mm or less, more preferably 0.5 mm or more and 1.3 mm or less. Further, the width Wb of the upper tactile portion of the guide portion 10 is preferably 0.5 mm or more and 1.5 mm or less, more preferably 0.5 mm or more and 1.3 mm or less. The cross-sectional shape may be rectangular, trapezoidal, etc., but is not limited to this, as long as the height from the surrounding surface and the width at the top fall within the above range. Further, even when the surrounding surface is not a flat surface but a curved surface, the height from the curved surface only needs to be within the above range.

Next, with reference to FIG. 5, the status display sections 5 of the toilet outdoor door opening/closing switch 1 and the toilet indoor door opening/closing switch 2 will be explained. FIGS. 5(a) and 5(b) are diagrams illustrating the display of the toilet outdoor door opening/closing switch 1. Fig. 5(a) shows the toilet in use, and the status display section 5 displays the letters ``IN USE'' to indicate that the toilet is in use. At this time, the push buttons for opening and closing are Since buttons 3 and 4 cannot be operated, the light emitting parts 6 on both push button parts 3 and 4 are in a non-emitting state. In FIG. 5(b), the toilet is empty and ready for use, and the status display section 5 lights up the word vacancy to indicate that the toilet is empty. At this time, the opening push button section 3 can be operated to open the door, so the light-emitting part 6 on the opening push-button part 3 emits light, while the closing push-button part 4 cannot be operated, so the light-emitting part 6 on the closing push-button part 4 emits light. It is in a non-emitting state. As described above, in the toilet outdoor door opening/closing switch 1 of the present invention, when the toilet is available and the room is vacant, not only does the in-use character on the status display section 5 not emit light, but also the word "vacant room" is displayed by emitting light. Therefore, the user can operate the light-emitting opening push button part 3 to open the door and use the toilet with peace of mind.
On the other hand, with the conventional toilet outdoor door open/close switch, when the toilet is empty and the same toilet can be used as shown in Fig. 5(b), the in-use characters on the status display section 5 are simply turned off, and the empty room characters are turned off. could not be made to emit light. Therefore, the characters in use are either dimly visible without being illuminated, or are almost invisible. A person who is used to using the toilet will know that the toilet is empty when the light emitting part 6 of the opening push button part 3 is lit, but if it is not, it may be difficult to judge whether the toilet is empty or not. In addition to displaying the status display section 5 as being in use only when the room is in use, the room is clearly displayed as vacant even when the room is vacant, so that even first-time users can use the room with confidence.

FIGS. 5(c) and 5(d) are diagrams illustrating the display of the door opening/closing switch 2 for the toilet room. In FIG. 5(c), the electric lock 25 of the door 2 is in a locked state, and the status display section 5 displays the words ``LOCKED'' to indicate that the door 2 is locked. Since the button section 3 can be operated to unlock the electric lock 25 and open the door 2, the light emitting section 6 on the opening push button section 3 emits light, while the closing push button section 4 cannot be operated. The light emitting section 6 on the closing push button section 4 is in a non-emitting state. In FIG. 5(d), the toilet is in an unlocked state, and the characters ``unlocked'' are lit on the status display section 5, indicating that the toilet is unlocked. At this time, since the opening push button section 3 can be operated to open the door, the light emitting section 6 on the opening push button section 3 is emitting light. On the other hand, depending on the conditions, the closing push button section 4 may be operated to lock the door, and in that case, the light emitting section 6 on the closing push button section 4 also emits light. As described above, in the toilet indoor door opening/closing switch 2 of the present invention, when the door is not locked, the status display section 5 not only makes the locked characters not emit light, but also displays the unlocked characters by emitting light. The user does not forget to lock the door, and can use the toilet by operating the closing push button part 4 that emits light to lock the door.
On the other hand, in the conventional toilet room door opening/closing switch 2, in the case of FIG. 5(d), the locked characters on the status display section 5 are only in a non-emitting state, and the unlocked characters cannot be made to emit light. Ta. Therefore, when the door is locked, the letters do not emit light and are either faintly visible or almost invisible. A person who is used to using the toilet will be able to tell that the toilet is unlocked when the light emitting part 6 of the closing push button part 4 is illuminated, but until then it was difficult to judge whether the toilet was unlocked or not, but with the present invention. By not only displaying ``locked'' on the status display only when the door is locked, but also clearly indicating ``unlocked'' even when the door is unlocked, even first-time users can use the door with confidence without forgetting to lock the door. .

Next, the operation of the automatic toilet door system and the voice guidance method will be explained using the flowcharts shown in FIGS. 6 to 8.
In FIG. 6, it is first determined whether the toilet 21 is in use (STEP 1), and if the toilet 21 is in use, the user approaches the toilet outdoor door open/close switch 1 and the outdoor proximity sensor 32 is turned on. (STEP 2), and if the proximity sensor is turned on, a guidance message informing the user that the toilet is in use, such as voice (1) ``The toilet is in use.'' Make a sound (STEP 3). In conventional automatic door systems for toilets, for example, when a user operates the opening push button part 3, there are systems that utter a guidance message informing the user that the toilet is in use; If the person with a disability knows that the toilet is in use before searching for and operating the opening push button part 3, the burden can be significantly reduced.
Note that in the above example, when the outdoor proximity sensor 32 detects the approach of a user while the toilet is in use, a voice message is uttered. When the toilet is inside, an audio message may be repeatedly uttered at predetermined time intervals to notify that the toilet is in use.
In addition, in places where passersby other than the toilet user pass near the toilet outdoor door open/close switch, when the outdoor proximity sensor 23 detects the user and continues to detect the user for a predetermined period of time, the toilet is closed. An audio message may be uttered to notify that the device is in use. This allows only those who really want to use the toilet to be informed that the toilet is in use, thereby suppressing unnecessary vocalizations.

Also, it is determined whether the toilet 21 is in use or not (STEP 1), and if the toilet 21 is vacant, it is determined whether the user approaches the toilet outdoor door open/close switch 1 and the outdoor proximity sensor 32 is turned on. (STEP 4), and if the proximity sensor 32 is turned on, a guidance message prompting the operator to operate the opening push button section 3 is uttered, for example, voice (2) "Press the upper button and the door will open." (STEP 5). Conventional automatic toilet door systems have used guidance messages such as "Press the open button to open the door." However, for visually impaired people who cannot visually recognize the opening push button 3, could not necessarily be said to be a highly effective guidance message. On the other hand, in the example of voice (2) above, the position and direction of the button to be operated can be notified, so the burden on the visually impaired person can be reduced.
Further, as a guidance message, for example, a voice (2) with an even larger amount of information, ``Press the shiny button on the upper side, the door will open.'' may be uttered. In this example, in addition to the location and direction of the button to be operated, it is also possible to tell the user that the button to be operated is lit, reducing the burden on people with low vision who cannot easily recognize text. .
A voice (2) as a guidance message prompting the operation of the opening push button part 3 is uttered (STEP 5), and when the opening push button part is operated and turned ON (STEP 6), a voice (2) is emitted as a guidance message to call attention (STEP 6). 3) After saying "The door is opening. Please be careful" (STEP 7), the door 22 opens (STEP 8).

In Figure 7, after the door opens (STEP 8), an example of a message prompting the user to move into the toilet is voice (4): "The door has opened. Please enter through the door on the front right." utter (STEP 9). Conventional automatic door systems for toilets have used guidance messages such as "The door has opened. Please come inside." This is not necessarily a highly effective guidance message for visually impaired people who are unable to visually recognize the location. On the other hand, in the example of voice (4) above, the position and direction of the open door 22 can be notified, so that the burden on the visually impaired person can be reduced. After that, the user moves into the toilet, reaches the vicinity of the toilet indoor door open/close switch 2, and determines whether the indoor proximity sensor 33 is turned on (STEP 10), and if the proximity sensor 33 is turned on, As a guidance message prompting the operation of the closing push button section 4, for example, a voice (5) "Press the lower button will close the door." or "Press the lower illuminated button and the door will close." Make a sound (STEP 11). According to these guidance messages, similarly to voice (2), it is possible to reduce the burden on visually impaired people and people with low vision.
A voice (5) as a guidance message prompting the user to operate the closing push button section 4 is uttered (STEP 11), and when the closing push button section 4 is operated and turned on (STEP 12), a voice message is emitted as a guidance message to call attention. (6) After uttering "The door is closing. Please be careful" (STEP 13), the door 22 moves to close (STEP 14). When the closing operation of the door 22 is completed, the electric lock 25 is locked, and as a guidance message to notify that the door 22 is locked, for example, voice (7) "The door is locked" is uttered (STEP 15), and the toilet is closed. is in use (STEP 16).
Note that the indoor proximity sensor 33 can also be omitted. In that case, for example, when the user reaches the vicinity of the toilet indoor door open/close switch 2 after a predetermined period of time has elapsed after uttering voice (4) "The door is open. Please come inside." For example, voice (5) ``Press the bottom button to close the door.'' or ``Press the bottom glowing button to close the door.'' may be uttered.

In FIG. 8, while the toilet is in use (STEP 16), it is determined whether or not the indoor proximity sensor 33 is turned on when the user finishes using the toilet and approaches the toilet indoor door opening/closing switch 2 (STEP 17). ), when the proximity sensor 33 is turned on, for example, utter voice (2) "Press the upper button and the door will open." or "Press the upper glowing button and the door will open." (STEP 18) . When the opening push button part 3 of the toilet indoor door opening/closing switch 2 is operated and turned ON (STEP 19), a voice (3) "The door is opening. Please be careful." is uttered as a warning message, for example. After that (STEP 20), the door 22 opens (STEP 21).

After door 22 opens (STEP 21), a guidance message prompting you to move outside the restroom may include, for example, voice (8): ``The door has opened. Please go outside through the door on your right and close the door. (STEP 22). Conventional automatic door systems for toilets have used guidance messages such as "The door has opened. Please go outside and close the door." This is not necessarily a highly effective guidance message for visually impaired people who cannot visually recognize whether the switch 1 is on the left or right side. On the other hand, in the example of voice (8), the position and direction of the open door 22 can be notified, so that the burden on the visually impaired person can be reduced.

Voice (8): "The door has opened. Please go outside through the door on the right and close the door." After saying (STEP 22), wait for the specified time (STEP 23) and let the user exit the toilet. For example, use voice (5) "Press the bottom button to close the door." or "Press the bottom glowing button to close the door." A guidance message prompting the person to operate the closing push button part 4 of the toilet outdoor door opening/closing switch 1 is uttered. This guidance message may be uttered when the outdoor proximity sensor 32 detects a user who has gone outside, but if the user who has gone outside forgets to close the door, the toilet outdoor door open/close switch 1 is activated. Since there may be cases where the user cannot approach, it is preferable to utter voice (5) after waiting for a predetermined period of time after uttering voice (8). In addition, instead of the voice (5), a guidance message that strongly urges operation, such as ``Press the bottom button to close the door.'' or ``Press the bottom glowing button to close the door.'' may be generated.
After the guidance message of voice (5) is uttered, when the closing push button part 4 of the toilet outdoor door open/close switch 1 is operated and turned ON (STEP 25), the guidance message of voice (6), for example, "The door is closed" is activated (STEP 25). After uttering "Closing. Please be careful" (STEP 26), the door 22 closes (STEP 27) and the toilet 21 becomes empty (STEP 28).

Although the voice guidance device has been described above as one that generates guidance messages in one language, the present invention is not limited to this, and guidance messages in two or more languages may be sequentially uttered. Furthermore, the number of languages to be uttered may be changed depending on the type of guidance message. Furthermore, depending on the type of guidance message, the number of times the guidance message is repeated and the time interval at which the guidance message is repeated may be changed.

(Example 2)
Embodiment 2 differs from Embodiment 1 only in the configuration of the toilet door opening/closing switches 1 and 2, especially the configuration of the guide section 10 and its related parts, so only the different configuration will be explained, and other embodiment 1 will be explained. Detailed explanation will be omitted for parts having the same configuration as .

The structure of the push button portion of the toilet door opening/closing switches 1 and 2 according to the second embodiment of the present invention will be explained with reference to FIG. 9, taking the toilet outdoor door opening/closing switch 1 as an example.
In FIG. 9(a), an opening push button section 3 and a closing push button section 4 are arranged with the status display section 5 in between. A relatively large guide portion 10 is formed to protrude in a cylindrical shape from the base surface of the pressing portion. The guide part 10 is different from the first embodiment in that it is formed in a cylindrical shape instead of a circumferential shape, but the base surface of the pressing part of the double push button parts 3 and 4 and the display surface of the status display part 5 are Even if they form a single surface, the columnar guide portions 10 on the pressing portions of both push button portions 3 and 4 will protrude high relative to the display surface of the status display portion 5, so that even visually impaired persons may This is the same as the first embodiment in that the protruding portion of the guide portion 10 can be relatively easily recognized as the double push button portions 3 and 4 by the sense of touch.

Near the center of the pressing parts of the double-push button parts 3 and 4, tactile symbols 8 and 9 having different shapes for opening and closing are further formed to protrude from the upper surface of the guide part 10, which is the surrounding surface. . That is, the surrounding surfaces of the tactile symbols 8 and 9 are the upper surfaces of the guide portions 10 that protrude from the base surfaces of the pressing portions of the push button portions 3 and 4, and are different from the first embodiment in that they are formed to protrude from there. However, when a visually impaired person recognizes the guide section 10 by touch, there is a high possibility that the tactile symbols 8 and 9 protruding from the top surface of the guide section 10 will be naturally touched. , 9 can be expected to have the same effect as in the first embodiment of recognizing the existence and position of the elements.
Further, the light emitting section 6 is also formed concentratedly on the upper surface of the cylindrical guide section 10 protruding from the base surface of the pressing section, resulting in a structure that is easy to manufacture.

The guide portion 10 has a diameter that is at least half the smaller width in the vertical and horizontal directions of the pressing portions of the push button portions 3 and 4, and is formed in a size that includes both the tactile symbols 8 and 9. The shape of the guide portion 10 is not limited to a cylinder, and the bottom surface may have a columnar shape such as an ellipse, an ellipse, or a rounded rectangle.

(Example 3)
Embodiment 3 differs from Embodiment 1 only in the configuration of the toilet door opening/closing switches 1 and 2, so only the different parts will be explained, and detailed explanations will be omitted for other parts that have the same configuration as Embodiment 1. do.

The structure of the push button portion of the toilet door opening/closing switches 1 and 2 according to the third embodiment of the present invention will be explained with reference to FIG. 10 using the toilet outdoor door opening/closing switch 1 as an example. FIG. 10 is a front view and a left side view of the toilet outdoor door opening/closing switch 1 of the third embodiment, but the toilet indoor door opening/closing switch 2 of the third embodiment also has the following features except for the characters displayed on the status display section 5. This is the same as FIG.
In FIG. 10, an opening push button section 3 and a closing push button section 4 are arranged with a status display section 5 in between. The double push button parts 3 and 4 of Example 3 differ from Example 1 and Example 2 in that the pressing part does not have a guide part 10 projecting in a circumferential or cylindrical shape, but as shown in the left side view, Since the entire pressing portions of the double push button sections 3 and 4 are formed to protrude from the display surface of the status display section 5, the fact remains that visually impaired people can easily recognize the double push button sections 3 and 4 through their sense of touch. .

Near the center of the pressing parts of both push button parts 3 and 4, a light emitting part 6 is provided which transmits light and emits light when an LED or the like (not shown) disposed on the back side of the pressing part emits light. There is. The light emitting part 6 of the opening push button part 3 consists of two arrows pointing outward, and the light emitting part 6 of the closing push button part 4 consists of two arrows pointing inward.The light emitting part 6 has a contrast when emitting light. Because of the high height, not only healthy people but also people with low vision can easily distinguish between open and closed positions by visual inspection. Further, as shown in FIG. 10, it is easier to identify if there is a slight gap between the two arrows, and it is preferable to leave a gap of at least 5 mm or more, preferably 10 mm or more. Also, it is easier for people with low vision to see the line of the light-emitting arrow if it is thicker than a certain level, and specifically, it is preferable to set it to 5 mm or more. Note that the shape of the light emitting part 6 is not limited to two arrows, but the combination of two arrows is easy to understand and does not require a large area, so it can be easily used for other characters, Braille parts, and tactile elements. It has a high degree of freedom in the size and arrangement of symbols, etc., and has the advantage of being easy to optimize each one.
Moreover, although the explanation has been made here assuming that the two arrows emit light, the two arrows may be made opaque, for example, black, and the area around the arrows may be used as the light emitting portion 6. Further, among the light emitting parts 6 of the double push button parts 3 and 4, one may use the two arrows as the light emitting part 6, and the other may use the light emitting part 6 around the two arrows.

A tactile symbol 8 is formed on the pressing portion of the opening push button portion 3, and a tactile symbol 9 is formed on the pressing portion of the closing push button portion 4, protruding from the peripheral surface of each tactile symbol. The shapes of the tactile symbols 8 and 9 are similar to those in Embodiments 1 and 2, but the tactile symbols 8 and 9 are not included inside the light emitting section 6, but are placed on the lower side a little away from the light emitting section 6. This differs from the first embodiment and the second embodiment in that it is arranged. However, the tactile symbols 8 and 9 do not need to be included in the light emitting part 6 because the shapes of the tactile symbols 8 and 9 only need to be recognizable by being touched by a visually impaired person with a fingertip. Healthy people and people with low vision can distinguish the opening and closing pushbuttons 3 and 4 by the shape of the high-contrast light-emitting part 6, and visually impaired people can identify the opening and closing pushbuttons 3 and 4 by touching the tactile symbols 8 and 9 with their fingers. Since the push buttons 3 and 4 for closing can be identified, the tactile symbols 8 and 9 do not need to be visually distinguishable; on the contrary, it is easier to understand if they are not conspicuous, so the tactile symbols 8 and 9 are set with the background color. It is best to use the same color. Furthermore, even if the tactile symbols 8 and 9 are not included in the light emitting part 6, the tactile symbols 8 and 9 are arranged in the pressing parts of the double push button parts 3 and 4, so the tactile symbols 8 and 9 Embodiment 1 has the advantage that there is no need to search for the pressing part again after identifying whether the push button part is for opening or closing, and the push button part can be operated simply by pressing the tactile symbol or its surroundings. and the same as in Example 2. Note that the size and shape of the tactile symbols 8 and 9 may be the same as in the first embodiment.

In addition to tactile symbols 8 and 9, Braille portions 7 are formed on the pressing portions of both push button portions 3 and 4 to protrude from the surrounding surface. In order to prevent confusion for visually impaired people, it is preferable that the Braille portion 7 is placed at a position 10 mm or more away from the rectangle circumscribing each of the tactile symbols 8 and 9. Further, it is preferable that the Braille portion 7 and the tactile symbols 8 and 9 be arranged vertically apart from each other rather than horizontally. In FIG. 10, the tactile symbols 8 and 9 are arranged below the light emitting part 6, and the Braille part 7 is arranged above the light emitting part 6, but conversely, the tactile symbols 8 and 9 are arranged above the light emitting part 6, and the Braille The section 7 may be disposed below the light emitting section 6. Also in the third embodiment, since the Braille part 7 is arranged at the pressing part of both push button parts 3 and 4, the pressing part is searched again after the Braille part 7 identifies whether the push button part is for opening or closing. This is the same as in the first and second embodiments in that the push button part can be operated by simply pressing the Braille part or its surroundings without any need for it.

In the third embodiment, there is no guide part 10 projecting in a circumferential or cylindrical shape on the pressing part, and there is a degree of freedom in the overall arrangement of the light emitting part 6, tactile symbols 8, 9, Braille part 7, letters, etc. In addition, since the two arrows of the light emitting part 6 do not require a large area, the letters such as "Open" and "OPEN" are made larger than in Examples 1 and 2 to make them easier to see even for people with low vision. There is. In order to make the characters more visible, the characters may be made to emit light as part of the light emitting section 6. Conversely, the letters may be opaque, for example black, and the light emitting portion 6 may be provided around the letters. Further, the light emitting portions 6 of the double push button portions 3 and 4 may emit light of different colors to make it easier to identify them.
