Description

  The present invention relates to an elevator operation panel, an elevator apparatus, and an elevator operation panel replacement method, and more specifically, an elevator operation panel having an operation unit for calling an elevator or instructing a destination floor, and the elevator operation panel for each floor. It is related with the elevator apparatus with which it equipped, and the replacement | exchange method of the existing elevator operation panel.

  Conventional push button devices provided on the operation panel of an elevator include one that detects a user's static electricity, one that is provided with a pressure-sensitive switch plate (see Patent Documents 1 and 2), and one that is provided with a strain gauge (Patent Document 3). For example).

  Of these, Patent Document 1 discloses a pressure-sensitive switch plate that is attached to the phase plate of the operation panel and supports the switch unit, a press plate that is inscribed in the flange portion of the frame, and a contact that is turned on when the press plate is pressed. In addition, there is described a push button switch for an elevator operation panel comprising a base fixed by screws to a frame and an elastic pad sandwiched between a push plate and a pressure sensitive switch plate.

  Further, in Patent Document 2, in a push button panel for an elevator push button having at least one push button area on the front surface of the front plate, the front plate is an integral part of the plate structure of the car wall or the getting-on / off floor wall. It is made of a material having high rigidity, and at least for each push button area, an element sensitive to pressure change is provided on the front plate, and the element is attached to the back side of the plate structure of the car wall or the getting-on / off floor wall. A push button panel is described.

  Further, Patent Document 3 is provided with a pressing member that can reciprocate in a certain direction via a guide member, and a leaf spring that is pressed by the pressing member to cause bending when the pressing member is pressed, and the leaf spring is distorted. An elevator push button provided with a biasing means for attaching a gauge and returning a pressed pressing member is described.

  However, the elevator push button for detecting the static electricity of the user may cause a poor sensitivity due to atmospheric humidity. Alternatively, in the case where the contact is turned on by the pressing force of the user as in the technique described in Patent Document 1, contact failure occurs due to intrusion of rainwater and generation of an arc, and the mechanically slidable portion is worn and the slide portion If an adhesive or the like is caught between the contacts, the contact may be continuously energized.

  In addition, as in the technique described in Patent Document 2, a pressure sensitive element that is sensitive to a pressure change for each push button region is attached to the back side of a plate structure such as a boarding / alighting floor wall, and the pressure change is detected from the back side. The structure is complicated and the pressure sensitive element is expensive.

  Furthermore, as in the technique described in Patent Document 3, in a push button in which a strain gauge is provided in the leaf spring portion, not only the strain gauge needs to be arranged in the leaf spring portion for each push button, but also in certain situations. If the push button is handled roughly, it may be easily destroyed and the function of the push button may be lost.

  Therefore, the problem to be solved by the present invention is that such an elevator operation panel does not cause poor contact contact, has no worn parts, and is not easily damaged even by rough operation.

In order to solve the above-mentioned problems, the present invention provides an elevator operation panel that is provided with a rigid surface plate on the operation side and performs operation input by pressing a predetermined position of the surface plate, the back surface side of the surface plate A plurality of strain gauges for detecting strain generated when the user presses the surface plate, detection means for detecting a pressing position of the surface plate of the user from outputs of the plurality of strain gauges, and the detection Registration means for performing call registration for raising or lowering the elevator based on the pressing position detected by the means, and the detecting means determines the pressing position of the surface plate from the distortion of the trajectory traced by the user. Detecting, the registering means judges ascending or descending based on the locus of the pressed position detected by the detecting means, and performs call registration of the elevator .

  According to the present invention, contact failure does not occur, there are no worn parts, and it is difficult to be damaged even by a rough operation.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  1A and 1B are views showing an elevator operation panel according to Example 1 of the present embodiment, where FIG. 1A is a front view, and FIG. 1B is a cross-sectional view taken along line AA in FIG.

  In FIG. 1, an elevator operation panel 9 connected to a cable 1 connected to an elevator control device is attached in a car and a landing (not shown) of the elevator. The elevator operation panel 9 includes a case 2 and a surface plate 8 provided at an opening of the case 2. The surface plate 8 is made of a metal plate having a strength that does not break even if a rough operation is performed, and the surface 4 is provided with first and second operation marks 3A and 3B made of arrows indicating the ascending and descending directions, and the elevator Can be operated. Further, the first and second strain gauges 6A and 6B are provided on the back surface 7 of the front plate 8 in the vicinity of the arrow tips of the first and second operation marks 3A and 3B and not overlapping the operation marks 3A and 3B. It is attached. The first and second strain gauges 6A and 6B are connected to the first and second lead wires 5A and 5B, respectively, and are connected to the cable 1 through the connector 1a inside the case 2, and an elevator control device (not shown). The detection signals of the first and second strain gauges 6A and 6B can be output to the side. In the present embodiment, the upper direction is indicated by a subscript A, and the lower direction is indicated by a subscript B.

  FIG. 2 is an explanatory diagram showing the state when the push button of the elevator operation panel 9 shown in FIG. 1 is operated, and shows the state of each part when the user does not press the surface plate 8 of the elevator operation panel 9 and when the user presses it. Yes. In this embodiment, there is no push button that slides by pressing scanning. However, since the pressing operation to the surface 4 of the surface plate 8 is detected and a detection signal is output, it is the same as the operation of pressing the button. This is referred to as a push button operation.

  In FIG. 2, the mounting position of the first strain gauge 6A on the surface plate 8 is 10A (hereinafter referred to as the first mounting position), and the mounting position of the second strain gauge 6B is 10B (hereinafter referred to as the second mounting position). The detected strain amount of the first strain gauge 6A is shown as 14A to 21A, and the detected strain amount of the second strain gauge 6B is shown as 14B to 21B. In addition, the first operation mark 3A provided on the surface 4 side of the surface plate 8 is shown as a first area 12A, and the second operation mark 3B is shown as a second area 12B. The center of the intermediate part of the strain gauges 6A and 6B is indicated by an intermediate line 13a.

  FIG. 2A shows a no-load (no operation) state. In the figure, when the user 14 operates the elevator operation panel 9, the first and second strain gauges 6A and 6B detect the first and second strain gauges 6A and 6B when the user 14 is not touching the surface 4 of the surface plate 8. The second distortion amounts 14A and 14B are “0”. That is, the initial value is 0.

  FIG. 2B shows a state when the user 15 performs a pressing operation above the first area 12A. The strain amounts detected by the first and second strain gauges 6A and 6B at this time are set as third and fourth strain amounts 15A and 15B.

  FIG. 2C shows a state when the user 16 presses the first area 12A. The strain amounts detected by the first and second strain gauges 6A and 6B at this time are defined as fifth and sixth strain amounts 16A and 16B.

  FIG. 2D shows a state when the user 17 presses the first region 12A side from the intermediate line 13a, which is the intermediate region 13 between the first and second regions 12A and 12B. The strain amounts detected by the first and second strain gauges 6A and 6B at this time are referred to as seventh and eighth strain amounts 17A and 17B.

  FIG. 2E shows a state when the user 18 performs a pressing operation on the intermediate line 13a of the intermediate region 13 between the first and second regions 12A and 12B. The strain amounts detected by the first and second strain gauges 6A and 6B at this time are referred to as ninth and tenth strain amounts 18A and 18B.

  FIG. 2 (f) shows a state when the user 19 presses the second region 12B side from the intermediate line 13a, which is the intermediate region 13 of the first and second regions 12A, 12B. The strain amounts detected by the first and second strain gauges 6A and 6B at this time are referred to as eleventh and twelfth strain amounts 19A and 19B.

  FIG. 2G shows a state when the user 20 presses the second region 12B. The strain amounts detected by the first and second strain gauges 6A and 6B at this time are set as the thirteenth and fourteenth strain amounts 20A and 20B.

  FIG. 2 (h) shows a state when the user 21 presses the lower portion of the second region 12B. The strain amounts detected by the first and second strain gauges 6A and 6B at this time are defined as the fifteenth and sixteenth strain amounts 21A and 21B.

  FIG. 3 is a flowchart showing a control procedure when the elevator operation panel shown in FIG. 1 is used. This control procedure is executed by a CPU of an elevator control device (not shown). The elevator control device includes a control unit including a CPU, a ROM, a RAM, an EPROM, and the like. The CPU is a central control unit that reads the program code stored in the ROM, develops it in the RAM, executes the program while using the RAM as a work area, and controls each unit. The RAM is also used as a data buffer, and the EPROM stores data used by the CPU for control.

  In FIG. 3, when the user 14 operates the elevator operation panel 9, the first strain gauge 6 </ b> A detects when the first region 12 </ b> A side is operated from the intermediate line 13 a like the users 15, 16, and 17. The first, third, and fifth strain amounts 15A, 16A, and 17A to be measured are larger than the second, fourth, and sixth strain amounts 15B, 16B, and 17B detected by the second strain gauge 6B. Therefore, elevator lift operation call registration is performed.

  Like the user 18, the middle line 13a portion of the first and second regions 12A and 12B is pushed, and the strain amounts detected by the first and second strain gauges 6A and 6B are the ninth and tenth strain amounts. In the case of 18A and 18B, since the distortion amounts of both are equal, the detected ninth and tenth distortion amounts 18A and 18B are reset 23, and the first and second distortion amounts 14A and 14A indicating the initial value 0 are reset. Return to 14B.

  On the other hand, when the second region 12B side is operated from the intermediate line 13a like the users 19, 20, and 21, the twelfth, fourteenth and sixteenth strain amounts 19B and 20B detected by the second strain gauge 6B are detected. , 21B are measured to be larger than the eleventh, thirteenth and fifteenth strain amounts 19A, 20A, 21A detected by the first strain gauge 6A, and therefore, the elevator uplift operation call registration is performed. In addition, when the elevator arrives at the waiting hall and the user gets in, the elevator call registration is canceled, the strain amount detected by the strain gauges 6A and 6B is reset, and the first and second values indicating the initial value 0 are displayed. Return to the strain amounts 14A and 14B.

  That is, the amount of distortion detected in the deformed state becomes the initial value 0, and the subsequent processing and determination are executed based on the initial value 0. If treated in this way, even if the surface plate 8 is permanently deformed due to rough handling, no malfunction or detection error will occur. This is because the strain amount detected by the first and second strain gauges 6A and 6B when the user operates the elevator operation panel 9 as shown in FIG. 2 (in step S104 described later). This is because the relationship (1) to (8) does not change. Therefore, it is possible to maintain the function of the elevator operation panel 9 until the surface plate 8 is replaced.

  Further, when the user 14 operates the elevator operation panel 9, the first and second regions 12 </ b> A and 12 </ b> B of the first and second operation marks 3 </ b> A and 3 </ b> B provided on the surface 4 of the surface plate 8 are operated. The rough operation is also performed around the regions 12A and 12B, but the first and second strain gauges 6A and 6B are positions that do not overlap with the first and second operation marks 3A and 3B. Since it is disposed on the back surface 7 of the front surface plate 8, no force acts directly on the first and second strain gauges 6A and 6B. Thus, the first and second strain gauges 6A and 6B are protected from the surface plate 8, and the durability performance against a rough operation by the user is also improved.

  The user's operation and the elevator control procedure will be described along the processing flow of FIG. 3. In the initial state, as shown in FIG. 2 (a), each of the first and second strain gauges 6A and 6B. The first and second distortion amounts 14A and 14B, which are distortion amounts, are equal (step S101), and are waiting for operation. In this state, when the user comes to the landing (step S102) and operates the push button (step S103), the CPU confirms which position on the surface plate 8 is pressed (step S104). This confirmation is determined based on the magnitude relationship between the strain amounts detected by the first and second strain gauges 6A and 6B and the difference between the two.

  That is, in step S104, as shown in FIGS. 2A to 2H, the following matters are determined according to the pressing positions of the surface plate 8 by the users 14 to 21.

(1) When the strain amounts detected by the first and second strain gauges 6A and 6B are equal and the detected strain amount is 0 (14A = 14B) (a)
(2) When the strain amount detected by the first strain gauge 6A is larger than the strain amount detected by the second strain gauge 6B and the difference between the two is large (15A> 15B, 15A-15B: large difference) Figure (b)
(3) When the strain amount detected by the first strain gauge 6A is larger than the strain amount detected by the second strain gauge 6B and the difference between the two is moderate (16A> 16B, 16A-16B: difference Middle) (c)
(4) When the strain amount detected by the first strain gauge 6A is larger than the strain amount detected by the second strain gauge 6B and the difference between the two is small (17A> 17B, 17A-17B: small difference) Figure (d)
(5) When the strain amount detected by the first strain gauge 6A is equal to the strain amount detected by the second strain gauge 6B and the strain amount is detected (18A = 18B) (e)
(6) When the strain amount detected by the first strain gauge 6A is smaller than the strain amount detected by the second strain gauge 6B and the difference between the two is small (19A <19B, 17A-17B: small difference) Figure (f)
(7) When the strain amount detected by the first strain gauge 6A is smaller than the strain amount detected by the second strain gauge 6B and the difference between the two is moderate (20A <20B, 20A-20B: difference Middle) Figure (g)
(8) When the strain amount detected by the first strain gauge 6A is smaller than the strain amount detected by the second strain gauge 6B and the difference between the two is large (21A <21B, 21A-21B: large difference) Figure (h)
Then, based on this determination, it is determined whether the user is 14 to 21, and based on the determination, whether the user is calling the ascending operation or performing the calling operation of the descending operation Is determined. Here, when the user corresponds to 15 to 17, the call registration for ascending operation is performed (step S104a), and when the user corresponds to 19 to 21, the call registration for descending operation is performed (step S104a). S104b).

  On the other hand, when the user corresponds to 18, the state (5) is established and it is impossible to determine whether the user is up or down, so the strain amount detected by the strain gauges 6A and 6B is reset (step S105). The first and second distortion amounts 14A and 14B are set to the initial value 0 (step S106), and the next push button operation is awaited. In this way, when the strain amount detected by the strain gauges 6A and 6B is larger than 0 but the input button operation cannot be determined, “the button operation cannot be determined. Press again. You may be notified by voice or display. In this way, it can be prevented that the user keeps waiting without input even though the user has operated the button.

  When the elevator arrives at the landing based on the call registration in step S104a or step S104b (step S107), the call registration is canceled (step S108) before the user gets in (step S110), and the detected distortion amount. Is reset (step S109). Then, the process returns to step S101 and waits for the next user operation. In step S104, if none of the users 15 to 21 is applicable, an abnormality may have occurred. Therefore, the strain amounts detected by the strain gauges 6A and 6B in step S109 are reset, and from step S101. Repeat the process. In this case, the same notification as described above may be performed.

  Further, in this embodiment, if the distortion amount detected in step S104 is stored in the memory M as distortion amount data, the time when the rough operation was performed can be known, so the operator who performed the rough operation is specified. It is also possible to do. Further, when a strain amount exceeding the limit strength of the surface plate 8 or the like is detected, or when a part replacement time comes based on the number of operations, the elevator manager is notified to that effect. You can also. Thus, if the said matter is reported, it will become possible to prepare the replacement part of the elevator operation panel 9 applicable beforehand when going to the field, and it can raise the efficiency of work.

Thus, according to the present embodiment,
The first and second strain gauges 6A and 6B for detecting the strain of the surface plate 8 generated when the surface plate 8 provided with the operation marks 3A and 3B that are easily understood by the user are pressed are provided. Since the first and second strain gauges 6A and 6B detect the strain generated when the operation marks 3A and 3B of 8 or the vicinity thereof are pressed, the contact failure does not occur.

・ Since there is no mechanical sliding part, there is no wear, and there is no necessary clearance in the mechanical sliding part by the surface plate 8, so there is no water immersion inside, so it is affected by external factors such as humidity. There is nothing to do.

-For the same reason, the structure can be simplified.

-Since the surface plate 8 is comprised with the metal plate which is not damaged even if a user performs a rough operation, the tolerance to a rough operation improves. As a result, reliability can be improved.

By storing the detected distortion amount in the memory M as distortion amount data, it is possible to identify an operator who performs a rough operation, improve maintenance efficiency, and the like.

There are effects such as.

It is a flowchart which shows the control procedure at the time of using an operation panel.

  The elevator operation panel according to the second embodiment is an elevator operation panel for an end floor in which the elevator call registration direction is determined in only one direction. As shown in FIG. 4, in the elevator operation panel 30 according to the second embodiment, an operation mark 31 is provided on the front surface 37 side of the front plate 32, and first and second strain gauges 34A and 34B are attached to the rear surface 33 side. It has been. Although one strain gauge in the second embodiment may be arranged directly below the back surface 33 of the surface plate 32 of the operation mark 31 shown in FIG. 4, as described above, the surface plate 32 of the operation mark 31 portion due to rough handling. In order to ensure the function of the elevator operation panel 30 even when the first and second strain gauges are permanently deformed, the first and second strain gauges 34 </ b> A and 34 </ b> B are arranged on the back surface 33 at a position not overlapping the operation mark 31. This improves the durability performance against rough operations. Furthermore, the dimension and positional relationship between the surface plate 8 of the elevator operation panel 9 shown in FIG. 1 and the first and second strain gauges 6A and 6B are compared with those of the surface plate 32 of the elevator operation panel 30 shown in FIG. If the dimensions and positional relationship of the second strain gauges 34A, 34B are the same, only the operation marks 3A, 3B and the operation marks 31 are changed in the surface plate 8 in the first embodiment and the surface plate 32 in the second embodiment. Parts can be shared. This also makes it possible to reduce production costs.

  In FIG. 5, the mounting position of the first strain gauge 34A on the surface plate 32 is 36A (hereinafter referred to as the first mounting position), and the mounting position of the second strain gauge 34B is 36B (hereinafter referred to as the second mounting position). The detected strain of the first strain gauge 34A is shown as 40A, 15A to 21A, and the detected strain of the second strain gauge 6B is shown as 40B, 15B to 21B (reference numerals 15A to 21A, and 15B to 21B are the same as in Example 1.) Further, the region of the operation mark 31 provided on the surface 37 of the surface plate 32 is shown as a region 38, and the intermediate portion of the first and second strain gauges 6 </ b> A, 6 </ b> B is shown by the intermediate line 39.

  FIG. 5A shows a state of no load (no operation). In the figure, when the user 40 operates the elevator operation panel 30, the first and second strain gauges 34 </ b> A, 34 </ b> B detect the first and second strain gauges 34 </ b> B when the user 40 does not touch the surface 37 of the surface plate 32. The second distortion amounts 40A and 40B have an initial value of 0.

  FIG. 5B shows a state when the user 15 presses the area 38 above. The strain amounts detected by the first and second strain gauges 34A and 34B at this time are defined as third and fourth strain amounts 15A and 15B.

  FIG. 5C shows a state in which the user 16 presses the region 38 above and below the region 38 in FIG. The strain amounts detected by the first and second strain gauges 34A and 34B at this time are defined as fifth and sixth strain amounts 16A and 16B.

  FIG. 5D shows a state when the user 17 presses the first strain gauge 34 </ b> A side from the intermediate line 39 in the region 38. The strain amounts detected by the first and second strain gauges 34A and 34B at this time are defined as seventh and eighth strain amounts 17A and 17B.

  FIG. 5E shows a state when the user 18 performs a pressing operation on the intermediate line 39 in the region 38. The strain amounts detected by the first and second strain gauges 34A and 34B at this time are referred to as ninth and tenth strain amounts 18A and 18B.

  FIG. 5 (f) shows a state when the user 19 presses the second strain gauge 34 </ b> B side from the intermediate line 39 in the region 38. The strain amounts detected by the first and second strain gauges 34A and 34B at this time are referred to as eleventh and twelfth strain amounts 19A and 19B.

  FIG. 5G shows a state when the user 20 performs a pressing operation below the region 38. The strain amounts detected by the first and second strain gauges 34A and 34B at this time are set as the thirteenth and fourteenth strain amounts 20A and 20B.

  FIG. 5 (h) shows a state when the user 21 presses the region 38 below the region 38 and further below FIG. 3 (g). The strain amounts detected by the first and second strain gauges 34A and 34B at this time are defined as the fifteenth and sixteenth strain amounts 21A and 21B.

  FIG. 6 is a flowchart showing a control procedure when the elevator operation panel shown in FIG. 4 is used. In FIG. 6, when the user 40 presses the surface plate 32, when the users 15, 16, 17, 18, 19, 20, and 21 press the surface plate 32 as shown in FIG. The strain amounts 15A, 15B, 16A, 16B, 17A, 17B, 18A, 18B, 19A, 19B, 20A, 20B, 21A, and 21B detected by the two strain gauges 34A and 34B are related to the strain amounts shown in FIG. As described above, if one or both of the first and second strain gauges 34A and 34B detect the strain amount, the elevator may be operated in the elevator operation direction predetermined by the operation call registration. When the user 40 gets in after the elevator arrives at the landing, the call registration is canceled and the strain amount detected by the first and second strain gauges 34A and 34B is reset to the initial value 0 as in the first embodiment. If the distortion amounts 40A and 40B are shown, even if the surface plate 32 is permanently deformed due to rough handling as in the first embodiment, there will be no malfunction or detection error.

  The operation of the user and the control procedure of the elevator will be described along the processing flow of FIG. 6. In the initial state, as shown in FIG. 5A, each of the first and second strain gauges 34 </ b> A and 34 </ b> B. The first and second distortion amounts 40A and 40B, which are distortion amounts, are equal (step S201), and are waiting for operation. When the user comes to the landing in this state (step S202) and performs a push button operation to push the surface plate 32 (step S203), the CPU confirms (determines) which position of the surface plate 32 has been pressed (step S203). Step S204). This confirmation is determined based on the magnitude relationship between the strain amounts detected by the first and second strain gauges 34A and 34B and the difference between the two (step S204). This magnitude relationship is as shown in S204 of FIGS. However, in the second embodiment, since the calling direction is single, it is sufficient that an output is generated in one of the first and second strain gauges 34A and 34B.

  Then, if an output is generated in one of the first and second strain gauges 34A and 34B, it is determined that the user 40 has performed a call operation, and corresponds to the arrow direction of the operation mark 31 of the operated surface plate 32. Call registration for ascending operation or descending operation is performed (step S205). The elevator arrives at the landing based on the call registration in step S205 (step S206), and when the user gets in (step S209), the elevator call registration is canceled (step S207), and the strain gauges 34A and 34B detect. The distortion amount is reset (step S208) to return to the first and second distortion amounts 40A and 40B indicating the initial value 0.

  In step S204, if none of the users 15 to 21 is applicable, an abnormality may have occurred. Therefore, the strain amounts detected by the strain gauges 34A and 34B in step S208 are reset, and step S201 is performed. Repeat the process from.

  Other parts not specifically described are configured in the same manner as in the first embodiment and function in the same manner.

Thus, according to the present embodiment, in addition to the effects of the first embodiment,
The circuit can be simplified because it is only necessary to detect the output of either the first or second strain gauge 34A, 34B. At that time, it is possible to share parts with the first embodiment, which can contribute to a reduction in production cost.

There is an effect.

  FIG. 7 is an explanatory view showing an example of an operation method of the elevator operation panel according to the third embodiment, and FIG. 8 is a state when the push button of the elevator operation panel is shown as a cross-sectional view along the line CC and DD in FIG. FIG. 9 is a flowchart showing a control procedure when the elevator operation panel shown in FIG. 8 is used. The configuration of the elevator operation panel is the same as that of the first embodiment.

  In Example 1, although the example which presses the vicinity of 1st and 2nd operation mark 3A, 3B was demonstrated, the operation of an operator is not restricted only to pressing operation. For example, you may trace from top to bottom or from bottom to top. FIG. 7A shows an operation state when the user traces downward (first locus 48A) from the upper position 47A to the lower position 47B, and FIG. 7B shows an operation state from the lower position 47C to the upper position 47D. The operation state is shown when tracing in the direction (second locus 48B).

  As shown as the first locus 48A, the amounts of strain detected from the first and second strain gauges 6A and 6B when tracing the surface plate 8 are 49A and 49B (FIG. 8A), and the second locus. The strain amounts detected from the first and second strain gauges 6A and 6B when traced like 48B are 50A and 50B (FIG. 8B), and the change state of the strain amount is detected. In the first trajectory 48A, the operator starts from the upper side of the first area 12A indicated by reference numeral 47A, the first area 12A, and an intermediate portion (intermediate area) between the first area 12A and the second area 12B. The second region 12B and the second region 12 indicated by reference numeral 47B are moved below, and the position and amount of distortion of the surface plate 8 change according to the position of the movement. In the second trajectory 48B, the operator starts from the lower side of the second area 12B indicated by reference numeral 47C, the second area 12B, and an intermediate portion (intermediate area) between the second area 12B and the first area 12A. The first region 12A and the first region 12 indicated by reference numeral 47D are moved above, and the distortion position and distortion amount of the surface plate 8 change according to the position of the movement.

  With this configuration, as shown in FIG. 9, the first and second distortion amounts 14A and 14B are equal in the initial state (step S301), and are in an operation waiting state. In this state, when the user comes to the landing (step S302) and performs a push button operation (step S303), the CPU is pressed to which position on the face plate 8 and how the pressed state changes. Is confirmed (step S304). This confirmation is determined based on the change in the magnitude relationship of the strain amounts detected by the first and second strain gauges 6A and 6B (change state of the strain amount). In this embodiment, when the distortion amount 50B> the distortion amount 50A in step S304a changes from the distortion amount 50A> the distortion amount 50B, it is determined that the operator has traced from the lower position 47C to the upper position 47D (FIG. 7 (b), FIG. 8 (b)), call registration for ascending operation is performed (step S304b). On the other hand, when the distortion amount 49A> the distortion amount 49B in step S304c changes from the distortion amount 49B> the distortion amount 49A, it is determined that the operator has traced from the upper position 47A to the lower position 47B (FIG. 7A). ), FIG. 8A), the call registration for the descent operation is performed (step S304b).

  Then, the elevator arrives at the landing based on the call registration in steps S304b and S304d (step S305), and when the user gets in (step S308), the elevator call registration is canceled (step S306), and the strain gauges 6A and 6B The detected distortion amount is reset (step S307) and returned to the first and second distortion amounts 14A and 14B indicating the initial value 0.

  Thus, when the user who has come to the landing presses the push button from the elevator operation panel 9, if the change in the distortion amounts 50A and 50B caused by the second locus 48B is in the relationship shown in step S304a, the call registration of the ascending operation is performed. If the change of the distortion amounts 49A and 49B caused by the first locus 48A is in the relationship shown in step S304c, if the call registration of the descent operation is performed, the elevator operation registration according to the operator's intention is performed. Can do. In this case, the operator only has to draw a trajectory so as to trace the surface 4 of the surface plate 8 and indicate the ascending or descending direction.

  In step S304, if none of S304a and S304c is applicable, an abnormality may have occurred. Therefore, the strain amounts detected by the strain gauges 6A and 6B in step S307 are reset, and the process from step S301 is performed. Repeat the process. At this time, notification similar to that in the first embodiment may be performed.

  10, 11 and 12 are front views of an elevator operation panel showing a modification of the present embodiment. In the present embodiment, the first and second strain gauges 6A and 6B are attached to the back surface 7 of the surface plate 8 near the tip of the arrow at a position that does not overlap with the first and second operation marks 3A and 3B. As shown in FIG. 10, the strain gauges 61 are placed on both sides of the front end portions of the first and second operation marks 3A and 3B, and at four locations surrounding the first and second operation marks 3A and 3B as shown in FIG. The provided elevator operation panels 62 and 63 can also be used. Thereby, the detection performance of the distortion amount of the elevator operation panels 62 and 63 can be improved.

  Further, as shown in FIG. 12, a region 65 is set on the surface 4 of the surface plate 8 of the elevator operation panel 64, and a plurality of strain gauges 61 are arranged in this region in a matrix (nine in FIG. 12). The user 66 may perform a touch operation so as to draw a locus 67 in the region 65 of the surface 4 of the face plate 8. With this configuration, it is possible to track the maximum value of the amount of distortion that occurs when a touch operation is performed, and therefore, ascending or descending operation is called from the change in the position of the maximum value or the state of the touch position toward the maximum value. You can also register and register the desired destination floor itself.

  Other parts not specifically described are configured in the same manner as in the first embodiment and function in the same manner.

Thus, according to the present embodiment, in addition to the effects of the first embodiment,
The call registration of the ascending operation or the descending operation can be performed only by detecting a change in the pressing (touch) operation position of the operator's face plate 8.

-If the change of the detected amount of distortion is measured, the trajectory of the user touching the surface plate 8 can be determined, so that the floor indicating the elevator operation panel or the mark indicating the driving direction becomes unnecessary.

-Since there is no need to indicate the floor or the operation direction on the elevator operation panel, it is possible to share parts and greatly reduce the cost.

There are effects such as.

  13A and 13B are views showing an elevator operation panel according to the fourth embodiment. FIG. 13A is a front view, and FIG. 13B is a cross-sectional view taken along the line EE of FIG. This embodiment is an example in which a protective plate 71 is attached to the surface 70 of the surface plate 69 in order to prevent the surface plate 69 from being repeatedly damaged by a rough operation on the existing elevator operation panel 68. As shown in FIG. 13, the elevator operation panel 75 according to the present embodiment includes first and second strain gauges 6 </ b> A and 6 </ b> B having operation marks 3 </ b> A and 3 </ b> B on the protective plate surface 72 and lead wires 5 on the protective plate rear surface 73. Is provided at the existing push button position 74. The existing push button position 74 is a position where a space is obtained by removing the slide button that has been slid and provided on the existing elevator operation panel 68. In the fourth embodiment, since the surface plate 69 is made of a plate material having metal rigidity as in the first embodiment, the surface plate 69 can be prevented from being repeatedly damaged due to a rough operation. That is, it can be set as the elevator operation panel 75 with a protective function.

  The protective plate 71 that prevents the surface plate 69 from being repeatedly damaged by a violent operation may cover the entire surface 70 as shown in FIG. 13, but as shown in FIG. It can also be covered only. 14A and 14B are views showing an elevator operation panel according to a modification of the fourth embodiment. FIG. 14A is a front view, and FIG. 14B is a cross-sectional view taken along the line FF of FIG.

  The elevator operation panel 81 according to this modification is provided with a small protective plate 80 at an existing push button position 74. As can be seen from FIG. 14A, the small protective plate 80 has a size that can cover the remaining portion after removing the sliding push button provided on the existing elevator operation panel 68. Good. An operation mark 77 is provided on the front surface 70 of the small protection plate 80, and a strain gauge 79 is provided on the back surface 78. In this modification, the strain gauge 79 is disposed so as to overlap the back side of the operation mark 77 in front view. The lead wire 5 extends from the strain gauge 79 to the connector 1a as in the first embodiment and is connected thereto.

  Thus, when the elevator operation panel 81 using the small protection plate 80 is used, the same protection effect as that of the elevator operation panel 75 shown in FIG. 13 can be obtained. In addition, even when there are a plurality of push button positions 74 of the existing elevator operation panel 68, if the top and bottom of the small protection plate 80a on the upper side and the small protection plate 80b on the lower side are reversed, they are provided on the existing elevator operation panel 68. Regardless of the number of push buttons, the elevator operation panel 81 can be configured. Furthermore, it becomes possible to cope with the ascending operation and descending operation operation panels only by reversing the top and bottom with the same shape. Accordingly, it is not necessary to prepare protective plates 71 having different shapes, and the mass production effect can be improved.

  Other parts not specifically described are configured in the same manner as in the first to third embodiments and function in the same manner.

Thus, according to this embodiment, in addition to the effects of Embodiments 1 to 3,
Since the strain gauges 6A and 6B are directly attached to the back surface 73 of the protective plate 71, the structure can be simplified, and the attachment work to the actual machine can also be simplified.

-Even if it is the existing elevator operation panel 68, it can be set as the new elevator operation panel 81 by attaching the small protection board 80 provided with the strain gauge 79 instead of the button installed originally. Alternatively, a new elevator operation panel 75 can be obtained by attaching the protective plate 71 on the surface plate 69 of the existing elevator operation panel 68. As a result, the operation panel 68 can be easily replaced or repaired to an existing elevator.
