  Referring to FIG. 1, a display device 30 according to an embodiment of the present invention is applicable to a POS terminal device (not shown) as a customer display device.

  As shown in FIG. 1, the display device 30 includes a base portion 33, a support tube 34, a fixed frame member 35, a support column 32, and a display portion 31. In FIG. 1, reference numeral 37 denotes a cable that is wired from the display unit 31 through the support column 32 and is electrically connected to a POS terminal device body (not shown).

  The base portion 33 is made of a resin material or metal, and leads the cable 37 (FIG. 1) from the flat top surface portion 33A and the support column 32 (FIG. 1), as shown in FIGS. For this purpose, and four screw hole portions 333 are provided. As shown in FIGS. 1, 7 (a) and 7 (b), 8, 9 (a) and 9 (b), the top surface portion 33 </ b> A is horizontally arranged along the width direction W and the depth direction D. . The base unit 33 can be configured by a part of the POS terminal device main body or a plate or the like attached to the settlement counter.

  The support cylinder 34 is made of a resin material having a low coefficient of friction, and as shown in FIGS. And a collar 342 provided at the end. As shown in FIGS. 1, 7 (a) and 7 (b), 8, 9 (a) and 9 (b), the support cylinder 34 rotates clockwise and counterclockwise in the direction indicated by the arrow R 34 around the cylinder axis. It is supported by the top surface portion 33 </ b> A of the base portion 33 so as to be able to rotate clockwise.

  The fixed frame member 35 is made of a resin material having a low friction coefficient, and, as shown in FIGS. A flange 352 provided at the base end portion and an annular recess 353 formed in an annular shape on the back side surface of the flange 352 are provided. The inner diameter of the annular recess 353 is slightly larger than the outer diameter of the flange 342 of the support cylinder 34 (FIG. 3 and the like). Further, the depth of the annular recess 353 is slightly larger than the thickness of the flange portion 342 of the support tube 34. In the flange portion 352, four empty hole portions 354 are formed corresponding to the four screw hole portions 333 (FIG. 5A) of the base portion 33.

  Referring to FIGS. 1, 7 (a), and 7 (b), the fixed frame member 35 has the top of the base portion 33 so that the annular recess 353 of the flange portion 352 covers the flange portion 342 of the support cylinder 34. It is attached on the surface portion 33A using four screws. Thereby, the fixed frame member 35 allows the support cylinder 34 to rotate, while preventing the support cylinder 34 from detaching from the top surface portion 33 </ b> A of the base portion 33.

  The support | pillar 32 consists of a resin material of a low friction coefficient, and as shown in FIG. 2, it is exhibiting the cylindrical shape extended in the cylinder axial direction X32. In FIG. 2, reference numeral 32 p indicates a proximal end portion, and reference numeral 32 d indicates a distal end portion. At least the base end portion 32p of the support column 32 is made of a resin material having a low friction coefficient. The inner diameter of the cylindrical portion 341 of the support cylinder 34 (FIG. 3 etc.) is slightly larger than the outer diameter of the support column 32.

  As shown in FIGS. 1, 5A to 5C, 7A and 7B, FIG. 8, FIG. 9A and FIG. 2) is inserted into the support tube 34 so as to be movable in the vertical direction.

  As shown in FIGS. 1, 2, 8 and 9A, the display unit 31 includes a screen 31A for displaying information. The display part 31 is supported by the terminal part 32d (FIG. 2) of the support | pillar 32, as shown in FIG.1, FIG.2, FIG.8, FIG.9 (a) and (b). In this example, the display unit 31 has a VFD as a display device. The display unit 31 is pivotable in the counterclockwise direction and the clockwise direction as indicated by an arrow R31 in FIG. 1 around the cylindrical axis of the support column 32 by the end portion 32d (FIG. 2) of the support column 32. It is supported. In this example, it can be rotated 120 degrees in the counterclockwise direction and the clockwise direction.

  In the display device 30, the support tube 34 includes a female screw portion 343 provided on the inner peripheral surface as shown in FIGS. 3 (a), 7 (a) and 7 (b). On the other hand, as shown in FIGS. 2, 8, 9 (a) and 9 (b), the support column 32 has a base end portion 32 p corresponding to the female screw portion 343 (FIG. 3A) of the support tube 34. The external thread part 321 provided in the outer peripheral surface is provided.

  Due to the screwed relationship between the support tube 34 and the support column 32, the support column 32 moves along the height direction (vertical direction) H based on the rotation of the support tube 34 in the direction indicated by the arrow R 34 as shown in FIG. Move up and down. The support column 32 is also supported at a height position when the support cylinder 34 is not rotated. As described above, the display device 30 can set the display unit 31 supported by the support column 32 to an arbitrary height position in a stepless manner by a simple operation of rotating the support cylinder 34. Further, the display unit 31 once changed to the desired height position is supported at the height position.

  Thereafter, the display unit 31 is rotated with respect to the support column 32 so that the screen 31A faces the optimum direction as necessary.

  In addition, due to the screwed relationship between the support tube 34 and the support column 32, the support column 32 is prevented from being unintentionally removed from the base portion 33 and the cable 37 being disconnected.

  By the way, although both the female screw part 342 of the support cylinder 34 and the male screw part 321 of the support column 32 are made of a resin material having a low friction coefficient, the weight of the support column 32 and the display unit 31 is relatively small between both screw parts. A frictional force is generated. Due to this frictional force, the support column 32 may also rotate with the rotation of the support cylinder 34. When the support column 32 is rotated, there is a risk that the cable 37 (FIG. 1) is twisted to cause a problem such as disconnection of the internal electric wire. For this reason, when rotating the support cylinder 34, it is necessary to rotate the support cylinder 34 with the other hand while holding the support column 32 so as not to rotate with one hand.

  As described above, since the operation requiring both hands is inconvenient, the display device 30 according to the present embodiment does not need to hold down the support column 32 when the support tube 34 is rotated, as will be described below. That is, the display device 30 further includes a rotation blocking mechanism that allows the column 32 to move in the vertical direction and blocks the column 32 from rotating.

  The rotation prevention mechanism is configured by a combination of the groove 322 shown in FIG. 2 and the protrusion 362 shown in FIGS. 6 (a), (c), (d), and (f).

  As shown in FIG. 2, the groove portion 322 is provided on the outer peripheral surface of the base end portion 31 p of the support column 32, and has a length parallel to the cylindrical axis direction X <b> 32 of the support column 32 and a width along the circumferential direction of the support column 32. And have. In addition, in this example, although the groove part 322 is bottomed shape, the hole shape penetrated inside the support | pillar 32 may be sufficient.

  On the other hand, the protrusion 362 is formed on the rotation preventing member 36 shown in FIGS. The rotation preventing member 36 is made of a resin material having a low coefficient of friction, and as shown in FIGS. A standing portion 361 extending in a substantially semicylindrical shape from the inner periphery of the portion 363 and a protruding portion 362 projecting inward from the inner surface of the standing portion 361 are provided. The oval or oval shape of the opening 364 has a major axis passing through the protrusion 362 and a minor axis orthogonal to the major axis in plan view. In addition, in the flange portion 363, four empty hole portions 365 are formed corresponding to the four screw hole portions 333 (FIG. 5A) of the base portion 33.

  Referring to FIGS. 9A and 9B, the rotation preventing member 36 is attached on the back surface of the top surface portion 33 </ b> A of the base portion 33 so that the protruding portion 362 is inserted into the groove portion 322 of the support column 32.

  The protrusion 362 can be relatively displaced in the length direction of the groove 322 relative to the groove 322, but is not inserted in the width direction of the groove 322 and is inserted into the groove 322. . Due to the positional relationship and the dimensional relationship between the groove 322 and the projection 362, the rotation prevention mechanism allows the support 32 to move in the height direction (vertical direction) H, while preventing the support 32 from rotating. As a result, when the support cylinder 34 is rotated, the support column 32 is not rotated with the rotation of the support cylinder 34.

  The groove portion 322 is further configured to have such a length as to limit the displacement range in the height direction (vertical direction) H of the protrusion portion 362 (relative displacement range of the protrusion portion 362 with respect to the groove portion 322), and thus rotation prevention. The mechanism also limits the movement range of the support column 32 in the height direction (vertical direction) H.

  Further, when the display unit 31 is configured to be rotatable with respect to the support column 32 as in this example by restricting the rotation of the support column 32, the support column 32 is rotated together when the display unit 31 is rotated. There is no end to it. Thus, the user can easily view the display unit 31 with only one hand without being forced to perform the troublesome work of rotating the display unit 31 with the other hand while holding the column 32 with one hand. Can be adjusted.

  Hereinafter, a method for assembling the display device 30 will be described more specifically.

  With reference to FIGS. 7A and 7B, first, the support cylinder 34 is temporarily placed on the top surface 33 </ b> A of the base portion 33.

  Next, the fixed frame member 35 is placed on the temporarily placed support cylinder 34. Subsequently, the fixing frame member 35 is positioned and fixed by screwing four screws into the four screw hole portions 333 of the base portion 33 with the flange portion 352 of the fixing frame member 35 interposed therebetween. do.

  Referring to FIG. 8, the male screw portion 321 of the support column 32 to which the display unit 31 is attached in advance is applied to the upper end of the support cylinder 34 positioned on the base unit 33. Subsequently, while the rotation of the support column 32 is prevented, the support tube 34 is rotated while lightly pressing the support column so as to allow movement in the vertical direction. By this operation, as shown in FIG. 8, the support column 32 is lowered until the screw portion 321 of the support column 32 appears on the lower side of the base unit 33.

  Referring to FIGS. 9A and 9B, the rotation preventing member 36 is put on the screw portion 321 of the support column 32 appearing below the base portion 33 from below and behind. At this time, the protrusion 362 is inserted into the groove 322 of the support column 32.

  Next, four nuts are attached to each of the four screws fixing the fixing frame member 35 to the base portion 33, and the rotation preventing member 36 is fixed to the back side surface of the base portion 33. That is, the fixed frame member 35 and the rotation preventing member 36 are fixed using a common screw. In addition, you may insert a washer between the empty hole part 365 formed in the collar part 363 of the rotation prevention member 36, and each nut as needed.

  Finally, the cable 37 (FIG. 1) is electrically connected to a POS terminal device body (not shown).
