Embodiments of the present invention will be described in detail below with reference to the drawings.
FIG. 1 is a perspective view showing an example of a POS terminal (product data processing device) 100 equipped with a display device 10 according to an embodiment of the present invention. This POS terminal 100 has a touch panel 111 installed on the front side of the upper part of a base 110, and a scanner section 113 for reading product barcodes (product identification information) and a printing section 115 below the touch panel 111. Also, a bill slot 117 is installed on the upper front side of the base 110, a coin slot 118 is installed diagonally below the slot, and a change outlet 119 is installed below the bill slot 117. There is.

A pole 1 is erected from the rear upper part of the base 110, and the display device 10 according to the present embodiment is installed on the upper part (upper end) of the pole 1. FIG. 2 is an enlarged perspective view of a main part of the display device 10. As shown in FIG. As shown in the figure, the display device 10 is attached to the upper end of the support column 1, has a light guide 70 protruding from the upper end surface of the outer case 20, and has a light guide 70 protruding from the upper end surface of the outer case 20, and is attached to each of the four outer circumferential sides of the outer case 20 facing in the horizontal direction. It is constructed by detachably attaching number display plates 90-1, 2, 1, 2 (only one number display plate 90-1, 2 is shown in the figure). Furthermore, a camera 130 is attached to the support 1 at the bottom of the display device 10. The structure of the display device 10 will be described below.

FIG. 3 is an exploded perspective view of the display device 10 (excluding the number display plate 90). As shown in the figure, the display device 10 includes a support 1, a case 50 (hereinafter referred to as "internal case") consisting of a pair of internal case components 51, 51 attached to the support 1 (see FIG. 4), and an internal case 50 (see FIG. 4). A case 20 (hereinafter referred to as "exterior case") consisting of a pair of exterior case components 21 and 21 attached so as to surround the outer periphery of the case 50, a lighting member 80 built in the inner case 50, and a light-emitting member 80 The light guide 70 is installed in the light guide 70.
Since the inner case 50, the outer case 20, the illumination member 80, and the light guide 70 are integrally fixed to the support 1, the width can be made wider than the width of the support 1.

The pillar 1 is made of a cylindrical rod member made of metal or resin, and is erected by having its lower end fixed to the base 110 of the POS terminal 100.

A pair of exterior case components 21 constituting the exterior case 20 are molded products having the same shape, and are formed into a substantially rectangular box shape with one side open. On the outer surface 25 of the exterior case structure 21 on the opposite side to the opened opening 23, there are three linear rails (plate locking mechanism) 27 that are approximately U-shaped and that attach and detach the number display plate 90-1. It is arranged in a shape. Although not shown, three linear rail portions (plate locking mechanisms) 27 may be arranged on the left, right and bottom, and may be provided so that the number display plate 90-1 can be inserted from the top.
Further, only two upper and lower rail portions (plate locking mechanism) 27 are provided, and a groove is further provided in the upper rail portion (plate locking mechanism) 27 that passes through the upper rail portion 27 in the longitudinal direction. You can also do it. In this case, prepare a number display plate 90 that is longer than the installation interval of the upper and lower rail parts (plate locking mechanism) 27, pass the number display plate 90 through the upper groove, and then insert the number display plate 90 into the lower rail part (plate locking mechanism) 27. Be supportive.

The inner side of each rail portion 27 serves as an insertion portion into which the outer periphery of the number display plate 90-1 is inserted. On the left and right outer surfaces 31, 31 of the exterior case 20, two linear rails (plate locking mechanisms) 33 are installed in parallel in vertical positions to which the number display plate 90-2 is attached and detached. . The opposing inner sides of each rail portion 33 serve as insertion portions into which the outer periphery (upper and lower sides) of the number display plate 90-2 is inserted. Furthermore, a pair of locking pawls 35 are provided protruding from the side of one of the outer surfaces 31 on the opening 23 side. Further, a locking recess 37 in which the locking pawl 35 is locked is formed on the side of the other outer surface 31 on the opening 23 side. A notch 39 for protruding the light guide 70 is formed on the upper side of the outer case structure 21 on the opening 23 side, and a cutout 39 is formed on the lower side of the outer case structure 21 on the opening 23 side as described below. A notch 41 is formed through which the support column holding portion 55 of the case structure 51 is inserted.

A pair of internal case components 51 constituting the internal case 50 are molded products of the same shape, and include a case main body 53 having a substantially rectangular box shape with one side open, and It is configured by integrally molding a semi-cylindrical column holding portion 55 that projects in the direction. A notch 57 for allowing the light guide 70 to protrude is formed in the inner case upper surface 61, which is the upper side of the case body 53. Although not shown, a holding mechanism for holding the illumination member 80 at a desired position is formed inside the case body 53. The inner diameter of the support column holder 55 is approximately the same as the outer dimension of the support column 1, and a female thread 59 into which a screw 77 is screwed is formed at a predetermined position in the lower part thereof. The female threaded portion 59 passes through. Further, although not shown, an engagement mechanism is provided at a predetermined position of the inner case structure 51 for engaging and fixing the other inner case structure 51.
Furthermore, the support column holding section 55 may be provided with a mechanism that allows only the display device 10 to be rotated. With this configuration, the orientation of the display device 10 can be easily adjusted depending on the installation location, with the support 1 fixed. This can be used, for example, when it is necessary to finely adjust the display device 10 while keeping the camera 130 fixed, as shown in FIG.

The lighting member 80 is configured by installing a plurality of light emitting elements 83 in one row on a rectangular circuit board 81. The light emitting element 83 uses a light emitting diode (LED) in this example, and emits light upward at a predetermined directivity angle.

The light guide 70 is constructed by forming a transparent synthetic resin material into a substantially trapezoidal flat plate. That is, the left and right sides 71, 71 of the light guide 70 are inclined inward so that the width thereof narrows upward. It is preferable that the thickness of the light guide 70 corresponds to the size of the light emitting element 83. It is necessary for the light guide 70 to efficiently emit light with effective intensity using the light emitted upward from the light emitting element 83, but if the thickness of the light guide 70 is too wide, the light may be diffused or weakened. This is because there is a possibility that
Furthermore, the left and right sides 71, 71 are subjected to surface treatment to effectively emit light from both sides. Thereby, the light guide 70 can be illuminated not only from the front but also from the side.
Moreover, since a substantially trapezoidal flat plate, which is not difficult to mold like a cylinder or a dome shape, is used as the light guide 70, parts can be procured at low cost.
Here, the light guide 70 may be made of any material, as long as it is a light-transmitting material such as an acrylic plate, a plastic plate, or a glass plate, and by using a cheap and lightweight material, it is possible to avoid damage. Replacement work can be done easily even in the case of

A locking piece 73 is provided from the lower part of both sides 71, 71 to protrude in the width direction. The transparent light guide 70 may be colored in a desired color (for example, green or red).
Further, a support member that can hold the light guide 70 in the inner case 50 may be provided. For example, a plurality of pins may be attached to the inner case 50 and fixed by fitting into holes provided in the light guide 70 in advance.

The light guide 70 has a wide width from the front, so visibility is good, and the colors being displayed can be seen even from a distance.
For example, with conventional cylindrical display devices, you could only check the displayed color based on the width of the cylinder. It was hard to see.
This allows customers and store staff to monitor the progress of each POS terminal (product data processing device) 100 by checking the illumination status of the light guide 70 at any position without having to go near the POS terminal (product data processing device) 100 to check the status. You can understand the situation etc.

Each of the number display plates 90-1 and 90-2 shown in FIG. ”) is displayed. For example, the number can be written directly on the board, but in this example it is displayed by pasting a sticker (number sticker) (the same applies to each of the following examples). The height and width of the number display board 90-1 are larger than those of the number display board 90-2.

The camera 130 shown in FIG. 2 includes an arm section 131, a column attachment section 133 attached to one end of the arm section 131, and a camera section 135 attached to the other end of the arm section 131. The strut attachment portion 133 is configured to be inserted into the strut 1 and attached to a desired position in the vertical direction and a desired position in the rotational direction. The camera unit 135 is configured so that a lens 137 faces diagonally downward and can record the entire operation surface side of the POS terminal 100.
The camera 130 is fixed so that it can always record the entire operation surface side of the POS terminal 100, but the display device 10 is provided with a mechanism that can be adjusted so that the direction can be changed depending on the installation position of the POS terminal 100. There is.

Next, in order to assemble the display device 10, first, the POS terminal 100 with the support 1 attached thereto is delivered from the factory to the site. At this time, the POS terminal 100 is placed on the truck, but since the display device 10 is not mounted on the support column 1, its height can be lowered. Therefore, the POS terminal 100 can be easily delivered.

Next, in order to assemble the display device 10 to the column 1 of the POS terminal 100 installed at the site, first insert the column attachment part 133 of the camera 130 from the upper end of the column 1 to which the display device 10 is not attached, and set it to a predetermined height. It is fixed at a predetermined angular position using a fixing means (not shown).

Next, as shown in FIG. 4, the pair of internal case components 51 are joined and integrated using an unillustrated engaging means (for example, an unillustrated retaining claw is engaged with an unillustrated retaining hole). An inner case 50 is configured. At this time, the illumination member 80 is housed in the upper part of the joined case body 53 and installed at a predetermined position. Further, the lower part of the light guide 70 is housed in the upper part of the light emitting member 80 inside the joined case main body 53, and in this case, the lower surface of the light guide 70 is placed on the upper surface of each light emitting element 83 of the light emitting member 80. Arranged so that they abut or approach each other. At this time, the upper part of the light guide 70 projects above the inner case upper surface 61 through the notch 57 of the joined inner case structure 51. On the other hand, the upper part of the pillar 1 is housed and held in the lower part of the joined pillar holding part 55. Then, the internal case 50 is fixed at a desired position and angle of the pillar 1 by screwing a screw 77 into the female threaded part 59 formed on one of the pillar holding parts 55 and pressing its tip against the outer surface of the pillar 1. .

This inner case 50 can be used as a display device even in this state (that is, the state shown in FIG. 4 without the outer case 50 attached), and a notification judgment that can notify an abnormality only by illuminating the light guide 70 is possible. It can be used as Further, at this time, a plate locking mechanism may be provided on at least one of the outer surfaces of the inner case 50 to detachably attach the number display plate.
Furthermore, since the light guide 70 can be displayed by switching between a plurality of colors, the types of guidance can be increased by combining various patterns such as lighting and blinking. For example, the light guide 70 can be illuminated in a predetermined manner to notify information such as machine failure, presence of trouble, call to a store staff, and current operating status.

Next, as shown in FIG. 5, the pair of exterior case components 21 are joined from the outside of the case body 53 of the joined inner case 50, and at this time, the locking claws formed on both exterior case components 21 are joined. 35 are respectively locked in locking recesses 37 formed on the other side, and are integrated to form the exterior case 20. At this time, the upper part of the light guide 70 projects upward through the notch 39 of the joined exterior case structure 21.

The outer case structure 21 is fitted and mounted so as to cover the upper part of the inner case upper surface (cutout surface) 61 of the inner case 50, with the light guide 70 protruding upward from the cutout part 39. Ru.

Next, as shown in FIG. 5, on the four outer surfaces 25, 31 (only one outer surface 25, 31 is shown in FIG. 5) on which the rail portions 27, 33 are provided, the respective rail portions 27, 33 are attached. A number display board 90 (90-1, 2, 1, 2) with dimensions suitable for the above is inserted and installed from the horizontal direction (direction perpendicular to the direction in which the support column 1 is erected). In this example, the rail parts (plate locking mechanisms) 27 and 33 are provided on all four outer surfaces 25 and 31 facing in the horizontal direction of the exterior case 20, but the plate locking mechanisms are provided on at least one of the outer surfaces. That's fine. This completes the assembly of the display device 10 shown in FIG. 2. Note that the above assembly procedure is only one example, and it goes without saying that assembly may be performed using various other assembly procedures.

As shown in FIG. 1, the display device 10 attached to the POS terminal 100 is installed on the top of the POS terminal 100 and is therefore easily visible. In addition, since the light guide 70, number display board 90, and camera 130 are attached to one pillar 1, installation work or layout change work can be done more efficiently than when each member is installed separately near the POS terminal 100. It can be carried out.

Then, when the light emitting element 83 emits light, the front (front and back surfaces with a large area) and side surfaces (left and right sides and upper side) of the light guide 70 are brightly illuminated. This lighting is a sign light (the same applies to each example below). FIG. 6 is a diagram showing a state in which the light guide 70 is illuminated by the light emitting element 83. As shown in the figure, the light emitted from each light emitting element 83 is emitted directly upward at a predetermined directivity angle, and is input into the light guide 70. The light incident on the light guide 70 is refracted and reflected on the inner surface of the light guide 70, and is emitted (scattered) in multiple directions. Here, since the left and right sides 71, 71 of the light guide 70 are obliquely inclined toward the inside, the light emitted directly upward from the light emitting element 83 is refracted and refracted by these inclined surfaces. The light is easily reflected, and both sides 71, 71 can be brightly illuminated. Furthermore, even if both sides 71, 71 are not sloped surfaces, but face vertically upward, the light emitted from the light emitting element 83 has a certain angle of direction and spreads, so these sides 71, 71 can be brightened. Can be lit. On the other hand, if both side surfaces 71, 71 are sloped surfaces that widen upward in the width direction, it becomes difficult for the light emitted from the light emitting element 83 to hit directly, so there is a risk that it will become dark. In view of the above, it is preferable that these both side surfaces 71, 71 be sloped surfaces that are vertical toward the top or sloped in a direction in which the widths thereof are narrowed toward the top.

Furthermore, the reason why the light guide 70 is configured to emit light from the light emitting element 83 upward from the bottom is to make the entire light guide 70 appear to be evenly and almost uniformly illuminated. It is. That is, since this light guide 70 is located above the level of the human eye, when a person looks at the light guide 70, the light emitted from the light emitting element 83 (light before reflection etc.) We do not see the light directly; we only see the reflected and refracted light. The light after being reflected and refracted is weaker than the light before being reflected and refracted, and is reflected and scattered in all directions, so the entire light guide 70 appears to be evenly illuminated. On the other hand, for example, if the light emitting element 83 is installed above or on the side of the light guide 70 and light enters the light guide 70, even if a person views the light guide 70 from below, the light emitting element 83 You can directly see the light emitted from the object (the light before it is reflected). Of course, you will also see reflected and refracted light at the same time, but the light before being reflected and refracted is stronger than the reflected and refracted light, so the part where the light emitting element 83 is installed becomes multiple points. Looks bright. That is, the entire light guide 70 does not appear to shine evenly, but instead appears to be a line of dotted lights.

In the above example, the number display plate 90 is attached, but the number display plate 90 may be omitted and a display device without a number may be used. Further, the rail portion 27 does not have to be installed on all the outer surfaces 25, 31, and may be installed only on one to three outer surfaces. Further, if the support column holding section 55 is configured to be bendable in the middle, the height can be reduced even when the POS terminal 100 is transported with the display device 10 attached to it at a factory.

As described above, the display device 10 includes the support 1 and the inner case 50 that is attached to the support 1 and has a light guide 70 protruding from the upper part and has a built-in light emitting member 80 that illuminates the light guide 70. , an outer case 20 attached to surround the outer periphery of an inner case 50, the inner case 50 is constructed by joining a pair of inner case structures 51, and the outer case 20 is configured by joining a pair of outer case members 51. It is constructed by joining the case components 21.

As described above, the display device 10 has a structure in which the light guide 70 installed on the top of the light guide member 80 is illuminated by the light guide member 80 built in the inner case 50 to display guidance, so the structure is simple. Therefore, the function of the display device 10 can be easily and reliably performed. Further, since the outer case 20 is attached to surround the outer periphery of the inner case 50, it is possible to easily display a number on the outer case 20. In addition, the inner case 50 is constructed by joining the pair of inner case components 51, and the outer case 20 is constructed by joining the pair of outer case components 21, so from this point of view as well, the structure is simple and easy. The display device 10 can be configured as follows.
Furthermore, since the exterior case 20 is formed by a simple configuration of the locking claw 35 and the locking recess 37 into which the locking claw 35 is locked, it can be easily removed. As a result, a configuration in which only the inner case 50 is used can be easily replaced with a configuration in which the entire display device 10 to which the outer case 20 is attached is used.

Further, in the display device 10, the pair of inner case structures 51 have the same shape, and the pair of outer case structures 21 also have the same shape. That is, since the pair of internal case components 51 and the pair of exterior case components 21 are each made of the same parts, it is possible to further simplify the configuration and reduce manufacturing costs.

Further, in the display device 10, the exterior case 20 has four outer surfaces facing in the horizontal direction, and a plate locking mechanism is used to removably attach the number display plate 90 to at least one of these four outer surfaces. Since the (rail portion) 27 is provided, the number display plate 90 can be attached to the surface of the exterior case 20. It is preferable to provide the plate locking mechanisms 27 on all four sides of the exterior case 20, since the number display plate 90 can be viewed from any direction.

Further, in the display device 10, among the four outer surfaces of the exterior case 20, the width of a pair of surfaces facing in opposite directions is smaller than the width of the other pair of surfaces. Thereby, the surfaces of the display device 10 that are visible to the customer can be enlarged as a pair of wide width surfaces of the front of the light guide 70 and the exterior case 20, and the other pair of narrow width surfaces. The display device 10 can be made to have a width that can be seen by a store clerk from any position, and can also simplify the configuration and reduce manufacturing costs, making it possible to make the display device 10 more compact. can.

Further, in the plate locking mechanism (rail portion) 27, the direction in which the number display plate 90 is attached and detached is perpendicular to the direction in which the support column 1 is erected. As a result, the mounting direction of the number display plate 90 to the plate locking mechanism 27 can be horizontal, and the mounting can be easily performed at a lower height than when mounting from the vertical direction, that is, from above.

FIG. 7 is a perspective view of a display device 10-2 according to another example. Previously, when POS terminals were delivered from the factory to the site and installed, the height had to be adjusted to the maximum height that could be placed on the truck bed and to approximately 1,900 mm, which was the appropriate height for the store. However, since it is desirable to use the display device immediately after delivery to the store, there is a need for a display device that eliminates the work of adjusting the height during delivery and installation.
This display device 10-2 includes an L-shaped holding mechanism 150 on the top of the support column 1, and a light guide 170 and a number display plate 180 attached to this holding mechanism 150.

The holding mechanism 150 includes an upper holding part 151 and a lower column fixing part 153, which are connected by a swinging mechanism such as a hinge mechanism (not shown). The swinging mechanism is attached to the support column fixing part 153 so that the holding part 151 swings toward the side where the number display plate 180 is installed (in the direction of arrow A). In other words, the swing mechanism is attached to the support column fixing part 153 so that the holding part 151 swings downward. Note that this swing mechanism may be any mechanism as long as the upper holding part 151 is bent with respect to the lower column fixing part 153. That is, without being limited to the hinge mechanism, for example, separate slide tubes that are movable up and down within a predetermined range are inserted into the respective tubes constituting the column fixing part 153 and the holding part 151, and these slide tubes are It may also be configured such that it is rotatably connected to both ends of the intermediate cylinder, whereby the holding part 151 is pulled up with respect to the column fixing part 153, and the connecting part is bent with the intermediate cylinder exposed between the two cylinders. good.

The column fixing part 153 is constituted by a columnar rod member, and is fixed to the upper end of the column 1 by a fixing means (not shown). Further, the column fixing portion 153 is configured such that its position in the rotational direction relative to the column can be changed by loosening the fixing means.

The holding part 151 is constituted by a substantially L-shaped rod-like member, and a light guide 170 is attached to the upper side of the holding part 151 so as to protrude upward. The light guide 170 has the same configuration as the light guide 70 shown in FIG. 3 above, so a description thereof will be omitted. A light-emitting member having the same structure as the light-emitting member 80 shown in FIG. Further, on the lower side of the horizontally extending portion of the holding part 151 (the lower side where the light guide 170 is attached), a rail holding part 155 having a T-shaped concave cross section is formed from the base to the tip. There is.

The number display board 180 is made of a synthetic resin formed into a substantially rectangular flat plate, with a rail section 181 having a T-shaped cross section on the upper side, and a desired number (in this example, " 12'') is displayed. The number is displayed by pasting a sticker, etc. Note that the number display board 180 is removably installed by inserting its rail portion 181 into the rail holding portion 155 of the holding portion 151 up to its root portion.

In the display device 10-2 configured as described above, when the illumination member (not shown) is turned on, the light guide 170 is displayed brightly. If it is desired to change the direction of the number display plate 180, the fixing means of the column fixing part 153 may be loosened, the position in the rotational direction relative to the column 1 may be changed, and the plate may be fixed again using the fixing means.

On the other hand, when transporting the POS terminal to which this display device 10-2 is attached, for example, from a factory, the number display plate 180 is pulled out toward the front and removed from the holding part 151 of the holding mechanism 150, as shown in FIG. As a result, the holding portion 151 swings downward under its own weight around the swinging mechanism (not shown), and its tip abuts against the support column 1 as shown in FIG. As a result, the height of the display device 10-2 is reduced, and the work of transporting the POS terminal can be carried out smoothly.

To install the number display board 180 on a POS terminal installed at the site, the reverse method to the above may be used, and the installation work can be easily performed. That is, by simply inserting the rail portion 181 of the number display plate 180 into the rail holding portion 155 of the holding portion 151 with the holding portion 151 of the holding mechanism 150 lifted upward, the installation state shown in FIG. 7 is achieved. At this time, one side of the number display plate 180 facing the column fixing part 153 comes into contact with the sides of both the lifted holding part 151 and the column fixing part 153, thereby holding the lifted holding part 151 in that position. It also functions as a holding member. Note that a holding member for holding the lifted holding part 151 in that position may be provided separately instead of the number display plate 180. Note that although no camera is installed in FIGS. 7 to 9, the camera may be attached to the support column 1 in the same manner as shown in FIGS. 1 and 2.

The display device 10-2 attached to the POS terminal is installed integrally with the top of the POS terminal, so it is easy to visually recognize it. Furthermore, since the light guide 170 and the number display board 180 (and the camera) are attached to one pillar 1, installation work or layout change work can be done more efficiently than when each member is installed separately near the POS terminal. It can be done easily and has a simple structure.

As described above, the display device 10-2 is attached to the column 1, the column fixing section 153 attached to the top of the column 1, and the column fixing section 153 attached to the top of the column fixing section 153 so as to be swingable with respect to the column fixing section 153. A holding mechanism 150 having a holding part 151 is provided, and a light guide 170 is attached to the holding part 151. Since the holding part 151 of the holding mechanism 150 is lowered by swinging, its height can be lowered, and the POS terminal can be transported and moved smoothly. Furthermore, after the conveyance or movement is completed, the operation of returning the holding portion 151 to its original position can be easily performed. That is, the height of the display device 10-2 attached to the tip of the support column 1 can be easily adjusted without the need for disassembly or the addition of parts.

Further, as described above, in the display device 10-2, the holding portion 151 is constituted by a substantially L-shaped rod member, the light guide 170 is attached to the upper side, and the number display plate 180 is attached to the lower side. It is installed. Thereby, the light guide 170 and the number display plate 180 can be mounted compactly.
