The extension connection cable 44 is configured such that the lower connector 44 a provided at the lower end portion thereof is connected to the pedestal side connector 27 b connected to the pedestal circuit portion 3 a in the pedestal 3.

  Further, as shown in FIG. 10, in the extension connection cable 44, the upper connector 44b provided at the upper end portion is connected to the display side connector 27a of the connection cable 27 connected to the display circuit unit 1b of the display device 1. Are configured to As a result, in the display circuit portion 1b of the display device 1 and the pedestal circuit portion 3a provided in the pedestal 3, the display side connector 27a of the connection cable 27 is connected to the upper connector 44b of the extension connection cable 44, and the extension connection cable The lower connector 44 a is connected to the pedestal connector 27 b in the pedestal 3 to be electrically connected.

  Similarly, as shown in FIG. 9, the second height adjustment support member 31 is formed such that the length in the vertical direction is longer than the length in the vertical direction of the first height adjustment support member 30, Except for this, the configuration is identical to that of the first height adjustment support member 30. Also in this case, an extension connection cable (not shown) is disposed in the second height adjustment support member 31. The extension connection cable is formed to be longer than the extension connection cable 44 of the first height adjustment support member 30, and the extension connection cable 44 of the first height adjustment support member 30 is other than this. It has the same configuration.

Next, the operation of such a rotary display device will be described.
First, the case where this rotary display device is assembled without using the first and second height adjustment support members 30 and 31 will be described. At this time, first, the display device 1 is assembled to the device mounting member 2, and in this state, the connection cable 27 is connected to the display circuit portion 1a of the display device 1, and the connection cable 27 is connected to the mounting portion 5 of the device mounting member 2 Pull out to the outside of the mounting member 2.

  In this state, the rotary connection member 4 is attached to the attachment portion 5 of the device mounting member 2. At this time, the display-side connector 27 a of the connection cable 27 is inserted into the rotary connection member 4 and pulled out from the cylindrical shaft portion 13 of the rotary connection member 4. Then, the pair of support protrusions 12 of the rotation connection member 4 in the vertical rotation mechanism 7 are inserted into the attachment portion 5 of the device mounting member 2, and the pair of support protrusions 12 are provided in the attachment portion 5. Between the support arms 11 of the

  At this time, the pair of elastic shaft portions 10 provided on the pair of support protrusions 12 in the vertical rotation mechanism 7 are pushed in the direction in which they approach each other by the opposing portions 11 a of the pair of support arms 11. For this reason, the pair of elastic shaft portions 10 in the vertical rotation mechanism portion 7 is elastically deformed in the direction approaching each other by the slit holes 12a formed along the outer periphery thereof, and between the opposing portions 11a of the pair of support arms 11 Will be placed.

  In this state, when the pair of elastic shaft portions 10 correspond to the bearing portions 9 of the pair of support projections 12, the elastic shaft portions 10 are elastically deformed in the direction in which they are mutually spread, and the pair of elastic shafts The portion 10 is rotatably inserted and fitted in each bearing portion 9 of the pair of support protrusions 12. Thus, the rotary connection member 4 is rotatably connected to the device mounting member 2, and the vertical rotation mechanism unit 7 is configured. In this state, the device mounting member 2 is vertically rotated about the pair of elastic shaft portions 10.

  At this time, the pair of elevation elastic projections 17 movably engage with the pair of elevation racks 16 in the elevation adjustment mechanism 14. That is, the pair of elevation racks 16 is an inner surface of the mounting portion 5 of the device mounting member 2 positioned on an arc centered on the pair of elastic shaft portions 10 which is the rotation center of the vertical rotation mechanism portion 7, ie, a pair of elastic shafts It is integrally formed on the inner surface of the mounting portion 5 of the device mounting member 2 corresponding to each outer periphery of the pair of support protrusions 12 of the rotational connection member 4 provided with the portion 10.

  On the other hand, the pair of elevation angle elastic projections 17 of the elevation angle adjustment mechanism 14 are integrally formed on the upper outer periphery of the pair of support projections 12 of the rotary connection member 4. For this reason, when the pair of elastic shaft portions 10 is rotatably fitted to the bearing portions 9 of the pair of support protrusions 12, the pair of elevation angle elastic protrusions 17 are a plurality of locking teeth of the pair of elevation angle racks 16. Elastically engage between any of 16a. Thus, the elevation angle adjustment mechanism 14 is configured, the rotation angle of the device mounting member 2 in the vertical direction with respect to the rotational connection member 4 is restricted, and the elevation angle of the device mounting member 2 can be adjusted.

  Thereafter, the rotary connection member 4 is attached to the pedestal 3. At this time, the display connector 27 a of the connection cable 27 is connected to the pedestal connector 27 b of the pedestal 3 in advance. Then, the cylindrical shaft portion 13 formed at the lower part of the rotary connection member 4 is inserted into the fitting cylindrical portion 6 provided on the pedestal 3 in the horizontal rotation mechanism portion 8 and rotatably attached.

  At this time, the contact portion 13a provided on the upper outer periphery of the cylindrical shaft portion 13 rotatably contacts the upper end portion of the fitting cylindrical portion 6, and the height position of the rotational connection member 4 with respect to the pedestal 3 is restricted. Be done. Thus, the horizontal rotation mechanism 8 is configured, and the rotation connection member 4 is attached to the pedestal 3 so as to be rotatable in the horizontal direction around the axis of the fitting cylinder 6.

  In this state, the device mounting member 2 is rotatably held by the rotary connection member 4 in the vertical direction by the vertical rotation mechanism 7 provided at the upper portion of the rotary connection member 4 and provided at the lower portion of the rotary connection member 4. The rotary connection member 4 is rotatably attached to the pedestal 3 in the horizontal direction, which is about the axis of the fitting cylinder 6, by the horizontal rotation mechanism 8. As a result, the pedestal 3 and the device mounting member 2 are connected by the rotary connection member 4, and the device mounting member 2 is held above the pedestal 3 in this state.

  As described above, when the rotary connection member 4 is rotatably attached to the pedestal 3 by the horizontal rotation mechanism unit 8, the rotation elastic projection 19 is movably engaged with the rotation rack 18 in the rotation angle adjustment mechanism 15. . That is, the rotating rack 18 is integrally formed on the inner peripheral surface of the fitting cylindrical portion 6 of the pedestal 3. The rotary elastic projection 19 is integrally formed on the outer peripheral portion of the cylindrical shaft portion 13 of the rotary connection member 4, and the slit holes 20 are provided from the upper outer periphery of the rotary elastic projection 19 to both sides of the rotary elastic projection 19. .

  For this reason, when the rotary connection member 4 is rotatably attached to the pedestal 3, the rotary elastic projection 19 elastically engages between any of the plurality of locking teeth 18 a of the rotary rack 18. . Thereby, the rotation angle adjustment mechanism 15 is configured, the rotation angle in the horizontal direction of the rotation connection member 4 with respect to the pedestal 3 is restricted, and the rotation angle in the horizontal direction of the device mounting member 2 can be adjusted.

  Further, at this time, the restriction protrusion 22 provided on the outer periphery of the cylindrical shaft portion 13 in the rotation restriction portion 21 is elastically deformed in the radial direction by the slit holes 22a formed along the both sides of the restriction protrusion 22 from the upper outer periphery thereof. And movably inserted into the restriction groove 23 provided on the inner periphery of the fitting cylindrical portion 6 of the pedestal 3. That is, the restricting groove 23 is formed in the range of 320 degrees on the inner periphery of the fitting cylindrical portion 6 located below the rotating rack 18, and the cylindrical shaft portion 13 is formed between both ends of the restricting groove 23. The stopper part 23a which the control protrusion 22 of this contact | abuts is provided.

  Thus, when the rotary connection member 4 is rotated in a state where the restricting protrusion 22 of the cylindrical shaft portion 13 is inserted into the restricting groove 23 of the fitting cylindrical portion 6 of the pedestal 3, the restricting protrusion 22 is a restricting groove 23. Move inside Then, when the rotary connection member 4 rotates 320 degrees, the restricting projection 22 abuts on the stopper portion 23 a located between both ends of the restricting groove 23. Thereby, the rotational connection member 4 does not rotate more than one rotation.

  Furthermore, when the rotary connection member 4 is rotatably attached to the pedestal 3 by the horizontal rotation mechanism portion 8, a pair of upper sides provided in the lower portion of the cylindrical shaft portion 13 of the rotation connection member 4 in the lock mechanism portion 24 The elastic hook portion 25 is movably engaged with the engagement groove portion 26 provided on the inner peripheral surface of the fitting cylindrical portion 6 of the pedestal 3 along the circumferential direction.

  That is, the pair of upper elastic hook portions 25 are formed so as to protrude in the radial direction from the lower portion of the cylindrical shaft portion 13 of the rotary connection member 4, and a pair of upper slit holes 25a are provided along the axial direction on both sides thereof. There is. For this reason, the pair of upper elastic hook portions 25 are elastically deformed in the radial direction from the outer peripheral surface of the cylindrical shaft portion 13 by the pair of upper slit holes 25a. Further, the locking groove portion 26 is formed annularly along the circumferential direction on the inner peripheral surface of the fitting cylindrical portion 6 of the pedestal 3.

  Thus, when the cylindrical shaft portion 13 of the rotary connection member 4 is inserted into the fitting cylindrical portion 6 of the pedestal 3 from the upper side, the pair of upper elastic hook portions 25 of the cylindrical shaft portion 13 is formed by the pair of upper slit holes 25a. It is elastically deformed in the radial direction from the outer peripheral surface, and is inserted into the locking groove 26 and locked. In this state, even when the cylindrical shaft portion 13 of the rotary connection member 4 rotates in the fitting cylindrical portion 6 of the pedestal 3, even if the pair of upper elastic hook portions 25 rotationally move along the locking groove portion 26. The cylindrical shaft portion 13 of the rotary connection member 4 does not come out of the fitting cylindrical portion 6 of the pedestal 3.

Next, the operation of the thus-assembled rotary display will be described.
First, when the display device 1 is to be tilted in the front-rear direction, the device mounting member 2 of the vertical rotation mechanism 7 is against the engagement force of the pair of elevation angle elastic protrusions 17 with the pair of elevation angle racks 16 of the elevation angle adjustment mechanism 14. It may be rotated in the vertical direction about the rotation center.

  For example, in the case where the display device 1 is erected in a substantially vertical state, the lower portion of the device mounting member 2 is pushed toward the rotational connection member 4. Then, the device mounting member 2 rotates counterclockwise in FIG. 5 around the pair of elastic shaft portions 10 of the rotation connection member 4 which is the rotation center of the vertical rotation mechanism portion 7 and stands up. At this time, the pair of elevation angle elastic projections 17 of the rotary connection member 4 in the elevation angle adjustment mechanism 14 move relatively along the pair of elevation angle racks 16 of the device mounting member 2.

  That is, as shown in FIG. 5, the elevation elastic protrusions 17 resiliently move over the plurality of locking teeth 16 a of the elevation rack 16 while moving relatively counterclockwise along the elevation rack 16, and thus the elevation angle It is locked between the locking teeth 16 a located at the top of the rack 16. Thus, the rotation angle of the device mounting member 2 in the vertical direction with respect to the rotational connection member 4 is restricted, and the device mounting member 2 is held in a substantially vertical state.

  In addition, when tilting the display device 1 to an easy-to-view angle, pressing the upper portion of the device mounting member 2 toward the upper side of the rotation connection member 4 causes the device mounting member 2 to rotate about the rotation center 5 rotates clockwise in FIG. 5 around the pair of elastic shaft portions 10 of the connecting member 4 and tilts. Also at this time, the pair of elevation angle elastic projections 17 of the rotary connection member 4 in the elevation angle adjustment mechanism 14 move relatively along the pair of elevation angle racks 16 of the device mounting member 2.

  That is, as shown in FIG. 5, the elevation angle elastic projections 17 resiliently sequentially move over the plurality of locking teeth 16 a of the elevation angle rack 16 while moving relatively clockwise along the elevation angle rack 16, and thereby the elevation angle rack It is locked between the locking teeth 16 a located on the lower side of 16. Thereby, the rotation angle in the vertical direction of the device mounting member 2 with respect to the rotation connection member 4 is restricted, and the device mounting member 2 is held in a state of being inclined at a predetermined angle.

  On the other hand, when the display device 1 is to be rotated in the horizontal direction, the center of rotation of the horizontal rotation mechanism unit 8 against the engagement force of the rotation elastic projection 19 with the rotation rack 18 of the rotation angle adjustment mechanism 15. Should be rotated horizontally around the For example, when rotating the display device 1 in either the left or right direction, either the left or right side portion of the device mounting member 2 is pushed backward. Then, the device mounting member 2 rotates above the pedestal 3 centering on the axial center of the cylindrical shaft portion 13 of the rotation connection member 4 which is the rotation center of the horizontal rotation mechanism 8.

  At this time, the rotation elastic projection 19 of the cylindrical shaft portion 13 of the rotation connection member 4 in the rotation adjustment mechanism 15 moves along the rotation rack 18 of the fitting cylindrical portion 6 of the pedestal 3. That is, when the rotation elastic projection 19 moves along the rotation rack 18, the rotation elastic projection 19 resiliently climbs over the plurality of locking teeth 18a of the rotation rack 18 in order and any of the plurality of locking teeth 18a. Resiliently engage between Thereby, the rotation angle in the horizontal direction of the device mounting member 2 with respect to the pedestal 3 is restricted, and the rotation angle in the horizontal direction of the device mounting member 2 is adjusted.

  In this case, when the device mounting member 2 rotates around the rotation center of the horizontal rotation mechanism unit 8, the rotation restricting portion 21 of the rotation angle adjusting mechanism 15 restricts the rotation range of the device mounting member 2. That is, in the rotation restricting portion 21, the rotation connection member 4 rotates in a state where the restricting protrusion 22 of the cylindrical shaft portion 13 is inserted into the restricting groove 23 of the fitting cylindrical portion 6 of the pedestal 3.

  At this time, when the restricting protrusion 22 moves in the restricting groove 23 and the rotational connection member 4 rotates 320 degrees, the restricting protrusion 22 abuts on the stopper portion 23 a located between both ends of the restricting groove 23. Thereby, the rotational connection member 4 does not rotate more than one rotation. Therefore, the connection cable 27 connecting the display circuit portion 1b of the display device 1 and the pedestal circuit portion 3a of the pedestal 3 is not twisted more than one turn.

  By the way, when this rotary display device is used at a clearinghouse where the register is arranged, for example, when the display device 1 is used for the user of the register, there is no need to move the pedestal 3. The display device 1 can be directed to the user simply by rotating the horizontal rotation mechanism 8 in the horizontal direction. In this case, when the height of the display device 1 is too low and the display device 1 is difficult to see, the device mounting member 2 is rotated in the vertical direction by the vertical rotation mechanism 7 to tilt the device mounting member 2 upward. can do.

  In addition, even when the display device 1 is used for a customer, there is no need to move the base 3, and the display device 1 is directed to the customer only by rotating the device mounting member 2 horizontally by the horizontal rotation mechanism 8. be able to. In this case, when the height of the display device 1 is too low and it is difficult for the customer to see the display device 1, the device mounting member 2 is vertically rotated by the vertical rotation mechanism 7 to tilt the device mounting member 2 upward. It can be easy to see.

Next, the case where the height of the display device 1 is adjusted in this rotary display device will be described.
In this case, the rotary connection member 4 is removed from the pedestal 3 and, for example, a first height adjustment support that fits the height of the display device 1 among the first and second height adjustment support members 30 and 31. The member 30 is attached to the pedestal 3. At this time, first, when the rotary connection member 4 is removed from the pedestal 3, the display-side connector 27 a of the connection cable 27 is removed from the pedestal-side connector 27 b of the pedestal 3.

  Then, the lower connector 44a of the extension connection cable 44 having substantially the same length as the length in the vertical direction of the first height adjustment support member 30 is connected to the pedestal side connector 27b of the pedestal 3, and the extension connection cable 44 is The upper connector 44 b of the extension connection cable 44 is pulled out from the upper end of the first height adjustment support member 30 by being inserted into the height adjustment support member 30 of FIG. In this state, the first height adjustment support member 30 is attached to the pedestal 3.

  At this time, the lower cylindrical shaft portion 34 of the lower mounting mechanism portion 32 in the first height adjustment support member 30 is inserted and fitted into the fitting cylindrical portion 6 of the pedestal 3, and the lower lock of the lower mounting mechanism portion 32 The lower cylindrical shaft portion 34 of the first height adjustment support member 30 is locked to the fitting cylindrical portion 6 of the base 3 by the mechanism portion 35, and the lower side of the mounting cylindrical portion 6 of the pedestal 3 by the rotation stopping portion 45 The rotation of the lower cylindrical shaft portion 34 of the mounting mechanism portion 32 is blocked.

  That is, when the lower cylindrical shaft portion 34 is inserted into the fitting cylindrical portion 6 of the pedestal 3, the lower elastic hook portion 36 of the lower lock mechanism 35 is provided on the mating cylindrical portion 6 of the pedestal 3. It is elastically inserted and locked in the locking groove 26 which is a side locking groove. As a result, the first height adjustment support member 30 is attached to the fitting cylindrical portion 6 of the pedestal 3 in an upright state without being inadvertently pulled out of the fitting cylindrical portion 6 of the pedestal 3.

  At this time, the lower cylindrical shaft portion of the lower attachment mechanism portion 32 is provided between any one of the plurality of locking teeth 18 a of the rotating rack 18 provided on the inner peripheral surface of the fitting cylindrical portion 6 of the pedestal 3. The fixing projections 46 provided on the outer peripheral surface of the gear 34 are engaged and locked. As a result, the fixing projections 46 do not get over the plurality of locking teeth 18 a of the rotating rack 18 and are fixed to the rotating rack 18, so that the first height relative to the fitting cylindrical portion 6 of the pedestal 3 The lower cylindrical shaft portion 34 of the adjustment support member 30 does not rotate in the axial direction.

  In this state, the rotational connection member 4 is attached to the first height adjustment support member 30. At this time, first, the upper connector 44 b of the extension connection cable 44 in which the display side connector 27 a of the connection cable 27 connected to the display circuit unit 1 b of the display device 1 is located on the upper end side of the first height adjustment support member 30. Connect to In this state, the cylindrical shaft portion 13 which is the upper cylindrical shaft portion of the rotary connection member 4 is inserted into the upper fitting cylindrical portion 37 of the upper mounting mechanism portion 33 of the first height adjustment support member 30 and rotatably attached.

  At this time, the cylindrical shaft portion 13 of the rotational connection member 4 is locked to the upper fitting cylindrical portion 37 of the first height adjustment support member 30 by the upper locking mechanism portion 38 of the upper mounting mechanism portion 33. That is, when the cylindrical shaft portion 13 of the rotational connection member 4 is inserted into the upper fitting cylindrical portion 37 of the first height adjustment support member 30, the upper elastic provided on the cylindrical shaft portion 13 of the rotational connection member 4 The hook portion 25 is resiliently inserted and locked in the upper locking groove 39 of the upper fitting cylinder 37. As a result, the cylindrical shaft portion 13 of the rotary connection member 4 does not inadvertently come out of the upper fitting cylindrical portion 37.

  Further, when the rotary connection member 4 is attached to the first height adjustment support member 30 in this manner, the upper fitting cylindrical portion 37 of the first height adjustment support member 30 in the rotation angle adjustment mechanism 40 The rotation elastic projection 19 provided on the outer peripheral surface of the cylindrical shaft portion 13 of the rotation connection member 4 is engaged with the rotation rack 42 provided on the inner peripheral surface so as to be movable along the rotation rack 42.

  That is, in the rotation angle adjustment mechanism 40, the lower cylindrical shaft portion 34 does not rotate with respect to the fitting cylindrical portion 6 of the pedestal 3 by the rotation stopping portion 45 of the lower mounting mechanism portion 32. The plurality of locking teeth 42a are sequentially resiliently overcome and resiliently engaged between any of the plurality of locking teeth 42a. Thereby, the rotation angle in the horizontal direction of the device mounting member 2 with respect to the pedestal 3 is restricted, and the rotation angle in the horizontal direction of the device mounting member 2 is adjusted.

  Further, at this time, the rotation range of the rotation connection member 4 with respect to the first height adjustment support member 30 is restricted by the rotation restriction part 41 of the upper attachment mechanism part 33. That is, in the rotation restricting portion 41, the restricting protrusion 22 provided on the outer periphery of the cylindrical shaft portion 13 of the rotational connection member 4 is provided on the inner periphery of the upper fitting cylindrical portion 37 of the first height adjustment support member 30. In the state of being inserted into the restriction groove 43, the rotary connection member 4 is rotated.

  At this time, when the restricting protrusion 22 moves in the restricting groove 43 and the rotational connection member 4 rotates 320 degrees, the restricting protrusion 22 abuts on the stopper portion 43 a located between both ends of the restricting groove 43. Thereby, the rotational connection member 4 does not rotate more than one rotation. For this reason, the extension connection cable 44 disposed in the first height adjustment support member 30 and the connection cable 27 connected thereto are not twisted more than one rotation.

  Thus, even when the first height adjustment support member 30 is attached to the pedestal 3 to adjust the height of the display device 1, there is no need to move the pedestal 3, and the device mounting member 2 can be moved by the upper attachment mechanism portion 33. Only by rotating it in the horizontal direction, the display device 1 can be rotated in the horizontal direction to be changed into an easy-to-see direction. Also in this case, the device mounting member 2 can be rotated in the vertical direction by the vertical rotation mechanism unit 7 so that the direction of the device mounting member 2 can be inclined in an easy-to-see direction.

  By the way, when adjusting the height of the display device 1 to a higher level in this rotary display device, the first height adjustment support member 30 may be removed and replaced with the second height adjustment support member 31. That is, when the first height adjustment support member 30 is removed, the upper fitting cylindrical portion 37 of the upper attachment mechanism portion 33 in the first height adjustment support member 30 to the upper cylindrical shaft portion of the rotational connection member 4 Remove a certain cylindrical shaft portion 13.

  At this time, the attachment / detachment force of the lower attachment mechanism portion 32 detachably attached to the pedestal 3 is larger than the attachment / detachment force of the upper attachment mechanism portion 33 detachably attached to the rotary connection member 4. Therefore, when removing the cylindrical shaft portion 13 which is the upper cylindrical shaft portion of the rotational connection member 4 from the upper fitting cylindrical portion 37 of the first height adjustment support member 30 in the upper mounting mechanism portion 33, the lower mounting The lower cylindrical shaft portion 34 of the mechanism portion 32 does not come out of the fitting cylindrical portion 6 of the pedestal 3, and the cylindrical shaft portion 13 of the rotary connection member 4 is the upper fitting cylindrical portion of the first height adjustment support member 30. It can be removed from 37.

  That is, the lower elastic hook portion 36 provided on the lower cylindrical shaft portion 34 of the lower mounting mechanism portion 32 is not provided with a slit hole on the upper side thereof, and provided on the cylindrical shaft portion 13 of the rotational connection member 4 An upper slit hole 25a is formed on the upper side of the upper elastic hook portion 25 along the axial direction. For this reason, the elastic engagement force of the lower elastic hook portion 36 is formed larger than the elastic engagement force of the upper elastic hook portion 25.

  As a result, when the device mounting member 2 is removed from the first height adjustment support member 30, the lower cylindrical shaft portion 34 of the first height adjustment support member 30 is disengaged from the fitting cylindrical portion 6 of the pedestal 3 Without this, the cylindrical shaft portion 13 of the rotational connection member 4 can be removed from the upper fitting cylindrical portion 37 of the first height adjustment support member 30.

  As described above, when the rotary connection member 4 attached to the device mounting member 2 is removed from the first height adjustment support member 30, the cylindrical shaft portion 13 of the rotary connection member 4 is always supported by the first height adjustment The device mounting member 2 can be safely removed from the first height adjustment support member 30 because the device mounting member 2 can be removed from the upper fitting cylindrical portion 37 of the member 30, and the device mounting member 2 is thereby dropped. It is easy to use because there is no risk of damaging it.

  Thus, after removing the first height adjustment support member 30, the second height adjustment support member 31 can be attached to the pedestal 3 in the same manner as the first height adjustment support member 30, The rotary connection member 4 can be attached to the top of the second height adjustment support member 31. Thereby, the height of the display device 1 can be further increased. Also in this case, the extension connection cable 44 may be replaced with an extension connection cable (not shown) having the same length as the length of the second adjustment support member 31 in the vertical direction.

  As described above, according to this rotary display device, the device mounting member 2 for mounting the display device 1 as a device, the pedestal 3 positioned below the device mounting member 2, and the device mounting member 2 in the vertical direction A rotation connecting member 4 having an up-and-down rotation mechanism 7 rotatably held and a horizontal rotation mechanism 8 rotatably attached in the horizontal direction with respect to the pedestal 3 and coupling the device mounting member 2 to the pedestal 3; As a result, the assembly work can be easily performed with a simple structure in which the number of parts is suppressed, and productivity can be improved.

  That is, in this rotary display device, the rotary connection member 4 can be rotatably connected to the device mounting member 2 in the vertical direction by the vertical rotation mechanism unit 7, and the rotary connection member 4 is connected by the horizontal rotation mechanism unit 8. It can be connected to the pedestal 3 so as to be rotatable in the horizontal direction. Therefore, since the device mounting member 2 can be easily attached to the base 3 only by the rotary connection member 4, the structure is simple and no separate parts are required, so that the number of parts can be reduced and the assembly operation is performed. It is easy to improve productivity.

  In this case, the vertical rotation mechanism unit 7 includes a bearing unit 9 provided on the device mounting member 2 and an elastic shaft unit 10 provided on the rotary connection member 4 and elastically deformed in the axial direction of the bearing unit 9. The elastic shaft portion 10 of the rotational connection member 4 can be elastically deformed when the rotational connection member 4 is connected to the device mounting member 2 by including the and the elastic deformation of the elastic shaft portion 10. Thus, the elastic shaft portion 10 can be easily and easily fitted to the bearing portion 9 of the device mounting member 2, whereby the device mounting member 2 can be vertically moved with respect to the rotational connection member 4 centering on the elastic shaft portion 10 Can be mounted securely and well in a rotatable state.

  That is, the bearing portions 9 of the vertical rotation mechanism portion 7 are opposed to each other of the pair of U-shaped support arms 11 formed to be elastically deformed in the mounting portion 5 of the device mounting member 2 in a direction approaching or separating from each other. The elastic shaft portions 10 of the vertical rotation mechanism portion 7 are integrally formed in such a manner that they project upward on both upper sides of the rotary connection member 4 in a corresponding manner on the same axis. The elastic shaft portion 10 is formed integrally with the pair of support projection portions 12 formed on the upper surface of the elastic shaft portion 10 from the upper outer periphery of the elastic shaft portion 10 in a reverse U-shape. Can be fitted into the bearing 9 simply and easily.

  In this case, in the vertical rotation mechanism unit 7, the upper portion of the rotary connection member 4 is inserted from the lower side into the mounting portion 5 of the device mounting member 2 to support the pair of support protrusions 12 in the mounting portion 5. Since the pair of elastic shaft portions 10 can be made to be elastic in directions approaching each other by the respective slit holes 12a of the pair of support projections 12 only by being disposed between the arms 11, it is possible to simply do not need separate parts. The pair of elastic shaft portions 10 can be disposed between the facing portions 11 a of the pair of support arms 11.

  Further, in the vertical rotation mechanism unit 7, the pair of elastic shaft portions 10 is arranged in each of the pair of support projection portions 12 in a state where the pair of elastic shaft portions 10 is arranged between the opposing portions 11 a of the pair of support arms 11. Since the pair of elastic shaft portions 10 can be elastically deformed in the direction in which the pair of elastic shaft portions 10 can be spread apart if they correspond to the bearing portions 9, the pair of elastic shaft portions 10 can be easily attached to the bearing portions 9 of the pair of support protrusions 12. And it can be made to fit certainly. Thus, the rotary connection member 4 can be rotatably connected to the device mounting member 2, and the device mounting member 2 can be favorably rotated in the vertical direction with respect to the rotary connection member 4 around each elastic shaft portion 10. be able to.

  The horizontal rotation mechanism 8 also includes a fitting cylinder 6 provided on the pedestal 3 and a cylinder shaft 13 provided on the rotary connection member 4 and rotatably fitted on the fitting cylinder 6. Thus, when connecting the rotary connection member 4 to the pedestal 3, the cylindrical shaft portion 13 of the rotary connection member 4 is simply inserted into the fitting cylindrical portion 6 of the pedestal 3. Can be easily and easily fitted to the fitting cylindrical portion 6 of the pedestal 3, whereby the rotational connection member 4 is horizontal with respect to the pedestal 3 about the axial center of the fitting cylindrical portion 6 of the pedestal 3 It can be mounted reliably and well in a rotatable manner in the direction.
