DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In some drawings, some of the detailed reference numerals used in other drawings are omitted. In the following embodiment, directions such as the up-down direction will be described based on a state in which an example of a holding device according to this embodiment and an example of a communication device including the same are installed.

[0011] As shown in Fig. 3, the holding device 20 according to this embodiment includes a holding portion 31 that detachably holds the handset 16 at a position spaced apart in a direction perpendicular to the first direction from a cradle 11 that has a holding recess 12 that allows the handset 16 to be held on one side in the first direction. The holding portion 31 holds the handset 16 with at least a portion of the handset positioned on the other side in the first direction relative to the bottom 12a of the holding recess 12 of the cradle 11 (see also Fig. 7). This configuration allows for a thinner installation space in the first direction compared to a configuration in which the handset 16 is held on one side of the cradle 11 in the first direction. In other words, when the handset 16 is held in the holding portion 31, at a position spaced apart from the cradle 11 in a direction perpendicular to the first direction, at least a portion of the handset 16 overlaps with the cradle 11 as viewed in a direction perpendicular to the first direction, allowing for a thinner installation space in the first direction. This allows for improved installation flexibility of the telephone set 10 having the cradle 11 and the receiver 16.

[0012] 3 to 7, the holding device 20 is provided with an operating unit 37 that operates the switch unit 12b provided on the bottom 12a side of the holding recess 12 of the cradle 11 in conjunction with the attachment or detachment of the handset 16 to or from the holding unit 31. With this configuration, the switch unit 12b of the cradle 11 can be operated by attaching or detaching the handset 16 to or from the holding unit 31, that is, the state can be switched between a call-disabled state and a call-enabled state. In this embodiment, the holding device 20 is configured to be disposed so that the first direction is horizontal. The holding device 20 is configured to hold the handset 16, which is elongated in one direction, in a state in which its longitudinal direction is in the vertical direction, which is perpendicular to the first direction. This configuration makes it easier to grip the wall-mounted handset 16. The holding device 20 is configured to hold the handset 16 on one side of the cradle 11 in the left-right direction, which is perpendicular to the first direction. This configuration allows for a more compact installation space in the vertical direction compared to a configuration in which the handset 16 is held on one side of the cradle 11 in the vertical direction, and also improves the manageability of the cord 15 connecting the handset 16 to the cradle 11. Note that the cord 15 is not shown in FIG. 3 , and the cord 15 and handset 16 are not shown in FIG. 5 .

[0013] The communication device 1 according to this embodiment includes the holding device 20, and a communication unit 10 having a receiver 16 and a cradle 11 held by the holding device 20. In this embodiment, the communication device 1 is configured to be able to communicate with an emergency communication device provided in the car of an elevator 2 (see FIG. 1). As shown in Figures 1 and 2(a), the installation structure of the intercom 1 according to this embodiment is such that the cradle 11 of the intercom 10 and the holding device 20 that holds the handset 16 are installed within the hall frame (second vertical frame) 6 of the elevator 2. With this configuration, the intercom 10 and the holding device 20 can be housed within the hall frame (second vertical frame) 6, making them less likely to get in the way and improving their appearance. Furthermore, by using the holding device 20, the installation space can be made thinner as described above, and therefore the hall frame (second vertical frame) 6 can also be made thinner. The landing frame (second vertical frame) 6 is provided with a faceplate portion 7 that covers the cradle 11 and has a receiver opening 8 that allows the receiver 16 to be inserted and removed, and a cover 29 that opens and closes the receiver opening 8. With this configuration, the receiver opening 8 can be made compact without exposing the cradle 11, and the receiver opening 8 can be closed with the cover 29.

[0014] Specifically, elevator 2 is equipped with a car that stops at the landings on each floor of the building, car doors that open and close the entrances and exits of this car, landing doors 3 that open and close at the landings on each floor, and landing frames 4, 5, and 6 that define the entrances and exits opened and closed by the landing doors 3. Elevator 2 is equipped with appropriate guide rails, counterweights, drive devices, etc. that constitute an elevation drive mechanism that raises and lowers the car along an elevator shaft provided in the building. The landing frames 4, 5, 6 each include an upper frame 4 and a first vertical frame 5 and a second vertical frame 6 that form the vertical frames on both sides. The upper frame 4, first vertical frame 5, and second vertical frame 6 may have their surfaces flush with the wall surface of the landing, or may be provided so as to protrude from or be recessed into the wall surface of the landing. In this embodiment, a control panel 9 having a display unit that displays the car's stop position, lifting direction, etc., and a car call operation unit that is pressed to call a car, is provided on the second vertical frame 6, which is one of the vertical frames on both sides of the landing frame. This operation panel 9 is provided embedded in the second vertical frame 6 through an appropriate opening provided in the face panel portion 7 of the second vertical frame 6.

[0015] The receiver opening 8 is provided so as to be located above the operation panel 9. The receiver opening 8 is elongated in the vertical direction and is provided so as to penetrate in the thickness direction of the face plate portion 7, whose thickness direction is aligned with the wall thickness direction, which is the first direction (horizontal direction). The length and width of the receiver opening 8 along the vertical direction are set to appropriate dimensions so that the receiver 16 can be inserted and removed. The length and width of the receiver opening 8 may be set to appropriate dimensions from the perspective of making the cover 29 that opens and closes the receiver opening 8 compact. The length of the receiver opening 8 may be set to no more than twice the length of the receiver 16. The width of the receiver opening 8 may also be set to no more than twice the width of the receiver 16 (the dimension in the short direction when viewed in the first direction with the protruding direction of the receiver portion 18 described below aligned along the first direction).

[0016] When held by the holding device 20, the receiver 16 of the telephone set 10 has a generally rectangular shape that is elongated in the vertical direction when viewed in a first direction that is the opening direction of the receiver opening 8. At the upper end, which is one longitudinal end of the gripping portion 17 of the receiver 16, there is provided an earpiece 18 that protrudes toward the other side in the first direction (the back side of the receiver opening 8 when the receiver is held by the holding device 20) (see FIG. 6). An appropriate audio output unit is built into the earpiece 18. At the side (bottom) of the gripping portion 17 of the earpiece 18, there is provided a hooking recess 18a into which the hooking protrusion 13 provided on the cradle 11 can be inserted. A mouthpiece 19 is provided at the lower end, which is the other longitudinal end of the gripping part 17 of the receiver 16, so as to protrude toward the other side in the first direction (see FIG. 6). A suitable voice input unit is built into the mouthpiece 19. One end of the cord 15, one of which is connected to the cradle 11, is connected to the other end (bottom) of the mouthpiece 19, which is the side opposite to the gripping part 17.

[0017] 3 and 4, the cradle 11 of the handset 10 is a generally rectangular parallelepiped that is elongated in one direction. The cradle 11 is attached to the holding device 20 with its longitudinal direction aligned with the up-down direction and its thickness direction aligned with the first direction. The holding recess 12 of this receiving stand 11 is arranged at the upper end, which is one end in the longitudinal direction, so as to open toward the front side, which is one side in the first direction (the side of the surface panel portion 7 when placed within the second vertical frame 6), and toward the outside in the longitudinal direction, so that it can receive the earpiece portion 18 of the handset 16. As shown in Figures 3, 5, and 7, switch portion 12b is provided on bottom portion 12a of holding recess 12 facing one side in the first direction so as to be displaceable generally in the first direction, and serves as a so-called hook switch. When switch portion 12b is pressed down so as to retract to the other side in the first direction, a call is disabled (the call is disconnected). On the other hand, when the switch portion 12b is released and protrudes in the one side in the first direction, a call is enabled. Switch portion 12b is biased in the protruding direction by a biasing member such as an appropriate spring provided within cradle 11.

[0018] In the illustrated example, switch portion 12b is elongated in the vertical direction and is provided so as to be located at the center in the width direction of holding recess 12 (the same direction as the width direction of cradle 11) (see also FIG. 6). Furthermore, switch portion 12b is in a call-enabled state in which it protrudes to one side in the first direction, and the surface facing one side in the first direction is an inclined surface that inclines downward so as to move away from bottom portion 12a of holding recess 12. The cradle 11 is provided with a hooking projection 13 that is inserted into the hooking recess 18a of the handset 16 to enable hooking and holding of the handset 16. The hooking projection 13 is provided so as to protrude upward from the lower edge of the holding recess 12.

[0019] A receiving recess 14 capable of receiving a mouthpiece 19 of a handset 16 is provided at the lower end, which is the other longitudinal end, of the receiving base 11. The receiving recess 14 is provided so as to open toward one side in the first direction. In the illustrated example, the receiving recess 14 is provided so as to open toward a diagonally downward side (see FIG. 7). An attachment portion corresponding to an attachment portion 24 provided on a holding device 20 (described later) is provided on the other side (back side) in the first direction of the receiving base 11. Such an attachment portion may be a hook recess into which the hook-shaped attachment portion 24 is inserted. An appropriate cord is connected to the receiving stand 11 and is connected to an emergency communication device inside the car. The handset 16 and cradle 11 of the telephone set 10 held by the holding device 20 are not limited to the above-described configuration and may have various other configurations. For example, the telephone set 10 may be provided with a call button, dial button, or the like at an appropriate location.

[0020] The holding device 20 is provided with a case 21 which is fixed to an installation target and which is provided with a handset housing section 23 which houses the handset 16 held by the holding section 31, and a cradle housing section 22 which has an attachment section 24 to which the cradle 11 is attached and which houses the cradle 11. With this configuration, the handset 16 and the cradle 11 can be housed in the case 21, and the case 21 which can house them can be fixed to the installation target. In this embodiment, the installation target for this case 21 is the face panel section 7 of the second vertical frame 6 which constitutes the above-mentioned landing frame. The holding device 20 is provided with a cover 29 that opens and closes the opening of the receiver housing portion 23. With this configuration, the appearance can be improved by closing the opening of the receiver housing portion 23 with the cover 29. In this embodiment, the cover 29 also functions as a cover that opens and closes the receiver opening 8 described above. In other words, the case 21 is fixed to the rear side of the face plate 7 so that the opening of the receiver housing portion 23 is aligned with the receiver opening 8. In other words, the area of ​​the case 21 other than the receiver housing portion 23, including the cradle housing portion 22, is covered by the face plate 7.

[0021] The case 21 is a container-like structure with a bottom that opens to one side in the first direction. The case 21 has a generally rectangular shape that is elongated in the vertical direction when viewed in the first direction. The case 21 has a bottom plate that defines the inner side (bottom side) of the cradle housing section 22 and the handset housing section 23, which is the other side in the first direction. The case 21 has an upper plate that extends from the upper end of the bottom plate to one side in the first direction, a lower plate that extends from the lower end of the bottom plate to one side in the first direction, and side plate portions on both sides that extend from both widthwise ends of the bottom plate to one side in the first direction. The lower plate of the case 21 has insertion holes through which various cords and cables are inserted. The dimension of case 21 in the first direction may be an appropriate dimension so that handset 16 and cradle 11 can be accommodated and from the viewpoint of achieving a slim design. In the illustrated example, the depth dimension of case 21 (cradle accommodating section 22 and handset accommodating section 23) in the first direction is approximately the same as the dimension of handset 11 and handset 16 in the first direction (see FIG. 7), but it may be 1.5 times or less the dimension of handset 11 and handset 16 in the first direction.

[0022] The mounting portions 24 of the cradle housing portion 22 are provided on the bottom plate portion. As shown in Fig. 7, the mounting portions 24 are hook-shaped protrusions fixed to the bottom plate portion and protruding to one side in the first direction. The mounting portions 24 are provided at multiple locations (two locations in the illustrated example) spaced apart from one another in the vertical direction, and at multiple locations (two locations in the illustrated example) spaced apart from one another in the width direction of the bottom plate portion (see also Figs. 4 and 6). The case 21 is provided with fixing pieces 21a, 21a that are fixed to the front plate portion 7. In the illustrated example, the fixing pieces 21a, 21a are provided so as to extend outward in the up-down direction from one end portion in the first direction of the upper plate portion and the lower plate portion of the case 21, respectively.

[0023] The cradle housing section 22 is provided on one widthwise side within the case 21, and the handset housing section 23 is provided on the other widthwise side within the case 21. The case 21 is provided with a partitioning side plate section 25 that separates the cradle housing section 22 and the handset housing section 23 in the widthwise direction. The partition side plate 25 is plate-shaped and disposed so that its thickness direction coincides with the width direction of the case 21, and is provided so as to protrude from the bottom plate toward one side in the first direction at approximately the center of the case 21 in the width direction. This partition side plate 25 is provided so that its lower end abuts or is close to the lower plate of the case 21 and extends in the vertical direction so as to form a space between its upper end and the upper plate of the case 21. The illustrated example shows an example in which a partition upper plate is provided that partitions the upper end side of the receiver housing 23 so as to connect the upper end of the partition side plate 25 to the side plate on the receiver housing 23 side of the case 21. The lower end of this partition side plate 25 is provided with an insertion portion through which the cord 15 can be inserted.

[0024] The cover 29 is held so as to be freely openable and closable on one side plate of the case 21 that defines one widthwise side of the receiver housing 23. One side plate and the cover 29 are connected by a slide hinge 28 that constitutes a rotary connecting member. In the illustrated example, the upper and lower ends of the cover 29 are each rotatably connected to one side plate by the slide hinges 28, 28. The cover 29 has a knob 29a at its non-connecting end, which is gripped when the cover 29 is opened. The case 21 is provided with a catch portion 27 that keeps the cover 29 closed. In the illustrated example, catch portions 27, 27 are provided at the upper and lower ends of the partition side plate portion 25 that defines the other widthwise side of the receiver housing portion 23. These catch portions 27, 27 may be so-called magnetic catches that attract the non-connected end of the cover 29 by magnetic force. In this case, the cover 29 may be made of a ferromagnetic material such as steel, or the cover 29 may be provided with an appropriate attracted portion made of a ferromagnetic material at an appropriate location. The manner in which the cover 29 can be opened and closed and the manner in which the cover 29 is kept closed are not limited to the above-described manners, and various other modifications are possible.

[0025] 2(a) and 2(b), the holding portion 31 of the holding device 20 is provided with a receiving recess 34 that receives the earpiece 18 (see FIG. 6) of the handset 16. With this configuration, the receiving recess 34 of the holding portion 31 can receive and hold the earpiece 18 of the handset 16, which has a relatively large dimension in the first direction, and the installation space in the first direction can be made thinner more effectively. The holding device 20 includes a holding member 30 that integrally includes the holding portion 31 and the operating portion 37. This configuration simplifies the structure compared to, for example, a configuration in which the holding portion 31 and the operating portion 37 are provided separately and linked together so as to be interlocked by an appropriate interlocking mechanism. Holding member 30 is configured to be displaced in conjunction with the attachment or detachment of handset 16. Holding member 30 is provided with interference protrusions 39 that are in a position where cover 29 can be closed when handset 16 is held, but are in a position where cover 29 cannot be closed when handset 16 is detached from holding member 30. With this configuration, cover 29 cannot be closed when handset 16 is detached, so the user can be prompted to return handset 16 to the appropriate position.

[0026] As shown in Figures 3 to 7, the holding device 20 includes a biasing mechanism 40 that biases the holding member 30 upward when the handset 16 is detached from the holding member 30 so that the operating unit 37 is in a position where it releases pressure on the switch unit 12b. This biasing mechanism 40 allows the holding member 30 to move downward when the handset 16 is held by the holding member 30 so that the operating unit 37 is in a position where it presses the switch unit 12b. With this configuration, detaching the handset 16 from the holding member 30 releases pressure on the switch unit 12b, enabling calls to be made. On the other hand, if the handset 16 is held by the holding member 30 against the biasing force of the biasing mechanism 40, the handset 16 will move downward due to its own weight, pressing the switch unit 12b and disabling calls. The biasing mechanism 40 is rotatable around an axis (lever axis) 41 along the first direction, and includes a biasing lever 42 to which the holding member 30 is connected at one end and which is biased downward at the other end. With this configuration, the holding member 30 moves up and down as the biasing lever 42 rotates, and the operating portion 37 is displaced between a position where it presses the switch portion 12b and a position where it releases the pressure. This makes it possible to more efficiently bias the holding member 30 upward than, for example, a configuration provided with a biasing member that pushes or pulls the holding member 30 upward.

[0027] 2(b), the holding portion 31 of the holding member 30 includes a receiver-side holding portion 32 that defines a receiving recess 34 and holds the receiver 18, and a transmitter-side receiving portion 35 that defines a receiving recess 36 that receives the transmitter 19 below the receiver-side holding portion 32. With this configuration, the receiver 16 can be stably held by the receiver-side holding portion 32 and the transmitter-side receiving portion 35. The receiver-side holder 32 is formed in a four-sided frame shape so as to define the four peripheries of a receiving recess 34 that penetrates in the first direction. A hooking protrusion 33 that protrudes upward is provided on the lower frame of the receiver-side holder 32 and is inserted into the hooking recess 18a of the earpiece 18. With this configuration, the receiver 16 can be more stably held by inserting the hooking protrusion 33 into the hooking recess 18a of the earpiece 18 of the receiver 16 received in the receiving recess 34. The transmitter-side receiving portion 35 has a three-sided frame shape that penetrates in the first direction and defines a receiving recess 36 that opens downward. The upper frame of the transmitter-side receiving portion 35 and the lower frame of the receiver-side holding portion 32 are integrally formed via a connecting piece that extends in the vertical direction.

[0028] The holder 31 is provided displaceably at a midpoint in the first direction (depth direction) of the receiver housing 23 so as to be able to hold the receiver 16 within the case 21 (receiver housing 23) (see FIG. 5). As shown in FIGS. 4 and 6 , the holding device 20 includes a guide portion 26 that guides the vertical movement of the holding member 30, including the holding portion 31. The guide portion 26 may be a slide rail having an outer member and an inner member slidably connected to each other via an appropriate retainer. This configuration allows the vertical movement of the holding member 30 to be stably guided. In this case, one of the outer member and the inner member of the guide portion 26 may be fixed to the partition side plate 25, and the other may be fixed to one side frame of the receiver-side holding portion 32. In this case, appropriate stoppers may be provided at appropriate locations on the partition side plate 25 or the like to prevent the receiver-side holding portion 32 or the rail member fixed thereto from displacing outward in the vertical direction beyond the respective upper and lower limit positions. The guide portion 26 that guides the vertical movement of the holding member 30 is not limited to a slide rail and may have various other configurations.

[0029] The interference protrusion 39 is provided so as to be located above the receiver-side holding portion 32 of the holding portion 31. In the illustrated example, the interference protrusion 39 is provided so as to extend upward from the upper frame portion of the receiver-side holding portion 32, and is provided at a vertically intermediate portion of a connecting piece portion that connects an operating portion 37 (described later) to the holding portion 31. The partition upper plate portion is provided with an insertion hole through which a portion of the connecting piece portion above the interference protrusion 39 is inserted (see FIGS. 3 and 5). This interference protrusion 39 is formed to protrude to one side in the first direction. As shown in FIGS. 5 and 6 , when the handset 16 is detached and the holding member 30 is in the upper position, it is positioned at the same height as the upper sliding hinge 28 of the cover 29. If the cover 29 is closed in this state, the upper sliding hinge 28 interferes with the interference protrusion 39, making it impossible to close the cover 29. On the other hand, as shown in FIGS. 3 and 4 , when the handset 16 is held by the holding portion 31, that is, when the holding member 30 is in the lower position, the interference protrusion 39 is lower than the upper sliding hinge 28 of the cover 29. In this state, the upper sliding hinge 28 does not interfere with the interference protrusion 39, allowing the cover 29 to be closed. The interference protrusion 39 is not limited to a configuration that interferes with the sliding hinge 28, but may be configured to interfere with an appropriate position on the cover 29, or may have various other configurations. Furthermore, a configuration without such an interference protrusion 39 may be used.

[0030] The operating unit 37 is provided on one side (the side of the receiving base accommodating unit 22) in the width direction of the holding unit 31 (the same direction as the width direction of the case 21) so as to enable pressing and releasing the switch unit 12b of the receiving base 11 attached to the mounting portion 24 of the receiving base accommodating unit 22 as described above. The operating portion 37 is provided so as to be continuous with the upper end of a connecting piece portion that extends upward from the holding portion 31. The operating portion 37 includes a portion that extends from the upper end of the connecting piece portion to one side in the width direction of the case 21, a portion that extends from this portion diagonally downward to one side in the width direction, and a pressing portion that extends downward from this portion and presses the switch portion 12b. The illustrated example shows an example in which a protruding piece portion that protrudes toward one side in the first direction is provided on the pressing portion of the operating portion 37. 3 and 4, when the handset 16 is held in the holding part 31 (holding member 30 is in the lower position), the operation part 37 is also in the lower position, and the pressing part of the operation part 37 presses down the switch part 12b (see also the two-dot chain line in FIG. 7). On the other hand, when the handset 16 is detached from the holding part 31 (holding member 30 is in the upper position), the operation part 37 is also in the upper position, the pressing down of the switch part 12b is released, and the switch part 12b protrudes (see also the two-dot chain line in FIG. 7).

[0031] The biasing mechanism 40 is provided so as to be located in the upper end space inside the case 21 . The biasing lever 42 constituting this biasing mechanism 40 is elongated generally in the width direction of the case 21, and a middle portion of the longitudinal direction (approximately the center portion in the illustrated example) is held by the case 21 so as to be rotatable around a lever shaft 41. The lever shaft 41 is provided so as to protrude from the bottom plate portion of the case 21 toward one side in the first direction. The biasing lever 42 may be rotatably held by the lever shaft 41 via an appropriate bearing portion. Alternatively, an appropriate bearing portion may be provided on the case 21 side to rotatably hold the lever shaft 41 fixedly provided to the biasing lever 42. The biasing lever 42 has a first end portion on one longitudinal end side connected to the upper end portion of the connecting piece portion of the holding member 30, and a second end portion on the other longitudinal end side biased downward by a biasing portion 45. The first end portion of the biasing lever 42 and the upper end portion of the connecting piece portion of the holding member 30 are connected by a connecting shaft 44 so as to be rotatable about an axis along the first direction. A shaft insertion hole 38 (see FIG. 2(b)) through which the connecting shaft 44 is inserted is provided at the upper end portion of the connecting piece portion of the holding member 30, and a shaft insertion hole 43 through which the connecting shaft 44 is inserted is provided at the first end portion of the biasing lever 42. One or both of these shaft insertion holes 38, 43 are loose insertion holes that allow mutual displacement between the connecting piece portion of the holding member 30, which displaces in the up-and-down direction, and the first end portion of the operating lever 42, which displaces on an arc around the lever shaft 41. In the illustrated example, the shaft insertion hole 43 of the biasing lever 42 is an elongated hole whose major diameter is in the longitudinal direction of the lever.

[0032] The biasing portion 45 is a weight fixed to the second end of the biasing lever 42. With this configuration, the biasing portion 45 is less likely to deteriorate or produce abnormal noise, compared to a configuration in which the biasing portion 45 is a spring member. 4, when the handset 16 is held by the holding portion 31 (holding member 30 is in the lower position), the load that urges the first end side downward due to the weight of the holding member 30 and the handset 16 is greater than the load of the urging portion 45 that urges the second end side downward. In this state, the first end of the urging lever 42 is in the lower position (the second end is in the upper position). In the example shown, in this state, the urging lever 42 is arranged with its longitudinal direction aligned horizontally, which is the width direction of the case 21. On the other hand, as shown in Fig. 6, when the handset 16 is detached from the holder 31 (the holder 30 is in the upper position), the weight of the biasing portion 45 of the biasing lever 42 causes a larger load to bias the second end side downward than the first end side. In this state, the first end of the biasing lever 42 is in the upper position (the second end is in the lower position). In the illustrated example, in this state, the biasing lever 42 is obliquely disposed so that the second end side is lower than the first end side.

[0033] The biasing mechanism 40 may be configured with an appropriate spring member instead of the above-described embodiment in which the biasing portion 45 is a weight. The biasing mechanism 40 is not limited to a configuration including a biasing lever 41 that rotates around a lever shaft 42 along the first direction, but may be configured with an appropriate biasing member that biases the holding member 30 so as to push or pull it upward. Furthermore, for example, when the holding device 20 is disposed so that the first direction is the vertical direction, the biasing mechanism may be configured to bias the operating portion 37 of the holding member 30, which is displaceable in the first direction (vertical direction), toward one side in the first direction, or various other configurations may be used. In the above example, the holding device 20 is provided with a holding member 30 having a holding portion 31 and an operating portion 37 integrally therewith, but instead of this configuration, the holding portion 31 and the operating portion 37 may be separate bodies connected by an appropriate interlocking mechanism, or the like.

[0034] In the above example, the holding device 20 is provided with a case 21 that separates the cradle housing section 22 and the handset housing section 23, but one or both of the cradle housing section 22 and the handset housing section 23 may be omitted. If the cradle housing section 22 is not provided, for example, an operation section 37 (holding member 30) may be provided so that the switch section 12b of the cradle 11 attached to an appropriate attachment object can be operated. Furthermore, if the handset housing section 23 is not provided, a configuration may be provided in which an appropriate holding section is provided to hold the holding section 31 (holding member 30) in a displaceable manner. In the above example, the holding device 20 is provided with a holding portion 31 that holds the handset 16 in a horizontal direction that is perpendicular to the first direction of the receiving stand 11, but it may also be configured such that the holding portion 31 that holds the handset 16 is provided on one side of the receiving stand 11 in the vertical direction.

[0035] In the above example, the holding device 20 is disposed so that the first direction is the horizontal direction (a direction perpendicular to the vertical direction), but it may also be configured so that the first direction is the vertical direction. In the above example, the communication device 1 is installed inside the landing frame (second vertical frame 6) of the elevator 2, but the installation structure is not limited to this and may be, for example, inside the car of the elevator 2 or on a wall near the landing frame. Furthermore, the communication device 1 is not limited to a configuration used as an emergency communication device for the elevator 2, but may also be used as an intercom or the like that enables communication inside a building such as a residence, apartment building, or factory, or between inside and outside the building, or may be used for various other purposes. The configurations of the above-described members and parts of the holding device 20 according to this embodiment and the communication device 1 equipped with the same are merely examples, and various other modifications are possible.
