[0006] The embodiments of the present invention will be described below with reference to the drawings. However, the following drawings are created for illustrative purposes and may intentionally omit components that are not necessary for the explanation in order to make them easier to understand. Also, components may be intentionally enlarged or reduced in size for illustrative purposes and are not drawings that show an accurate scale. In the following description, the same reference numerals in different figures indicate parts with the same function, and redundant explanations in each figure will be omitted as appropriate. The embodiments of the present invention include, but are not limited to, those shown.

[0007] (Regarding the overall configuration of the data processing system) Figure 1 is a downward perspective view of a data processing device according to an embodiment of the present invention, where (a) is a front downward perspective view and (b) is a rear downward perspective view. In Figure 1(a), the left side is defined as the front, the right side as the rear, and the front as the right side. In Figure 1(b), the front and rear are reversed, with the left side as the rear, the right side as the front, and the front as the left side.

[0008] The data processing device 100 according to an embodiment of the present invention primarily serves as a POS terminal in stores such as supermarkets, where store employees perform registration and settlement associated with product sales. However, it is also envisioned that it may be used as a face-to-face device in which store employees provide necessary support to customers when they perform registration and settlement.

[0009] As shown in Figures 1(a) and 1(b), the data processing device 100 according to an embodiment of the present invention has a trapezoidal shape in side view, with the housing covered by a left side cover member 3 and a right side cover member 4. That is, the front and back surfaces are inclined surfaces with a gap that widens towards the bottom. Utilizing these inclined surfaces, the first display unit 1 is attached to the front side and the second display unit 2 to the back side by connecting parts, with a simple structure that allows for an angle suitable for viewing, and they can be easily attached and detached. Furthermore, the connecting parts are hinges with a free-stop specification, such as torque hinges, and are configured to allow fine adjustment of the viewing angles of the first display unit 1 and the second display unit 2. Also, because the housing is trapezoidal, a larger internal space can be secured towards the bottom. These features are advantageous in arranging interface connectors and routing the cords connected to them, as will be described later.

[0010] In this embodiment, the first display unit 1 is for staff use and the second display unit 2 is for customer use, but the order may be reversed. Also, in this embodiment, the size of the first display unit 1 is larger than that of the second display unit 2, but they may be of similar size. Below the connection part to which the first display unit 1 is connected, an expansion connector section is provided for connecting an accessory device such as an SSD. Figure 1(a) shows the expansion connector section covered by a cover.

[0011] An interface connector IF is provided in the area below the connection point to which the second display unit 2 is connected, utilizing the space created by the trapezoidal shape of the housing. More specifically, the interface connector IF is located in the area below where the second display unit 2 is located, separated from the inner surface of the housing by space. This is achieved by the fact that the main board unit 6 is located on the bottom side of the housing, as will be described later. In Figure 1(b), the interface connector IF is covered by a cover, but a part of the terminal is visible through the cord communication hole 52 provided on the bottom surface 5 of the housing, which will be described later.

[0012] As can be seen from the bottom surface 5 of the housing, the data processing device 100 according to the embodiment of the present invention is provided with four skirt portions 51, 51, 51, 51 at the extensions of the bottom sides of the front, back, and both sides of the housing, giving the device a sleek appearance. Here, the skirt portions 51 on the front, back, and both sides have notches. In addition, a cord passage hole 52 is provided on the bottom surface directly below where the interface connector IF is located, and the device is configured so that the cord can be passed to the outside of the data processing device 100 through any of the aforementioned notches. As mentioned above, the interface connector IF is located in an inner position separated from the inner surface of the housing, and there is ample space, so the cords can be passed through the cord passage hole 52 without being bent forcibly, and as a result the cord routing around the data processing device 100 can be kept in an orderly state.

[0013] As mentioned above, there are four notches on the front, back, and both sides. In particular, the notch on the back is convenient for routing the cord that extends downward through the cord passage hole 52 located on the bottom surface 5 directly below where the interface connector IF is located. The notch on the front is convenient for routing the power cord.

[0014] Figure 2 is a side view of a data processing device according to an embodiment of the present invention with the side cover member removed, where (a) is a right side view and (b) is a left side view. As shown in Figure 2, the main board unit 6, power supply board unit 7, and printer 8 are arranged in order from bottom to top in the internal housing structure IB (in Figure 2, the arrangement is complex with many components and therefore not numbered; please refer to Figures 3, 5, and 7), which can be confirmed by removing the left side cover member 3 and the right side cover member 4. The main board unit 6 can be considered a composite unit of boards in which an IF board, expansion connector board, etc. are connected and fixed to the main board (control circuit board). Similarly, the power supply board unit 7 also has attached boards etc. connected and fixed, and can be considered a composite unit.

[0015] Because the power supply board unit 7 is located above the main board unit 6, the heat from the power supply board unit 7 does not adversely affect the main board unit 6. Also, by placing the main board unit 6 in the bottom layer of the third layer, the interface connector IF and expansion connectors are located at the bottom, making it easy to insert and remove cables and external memory such as SSDs. To reiterate, the trapezoidal shape of the chassis is advantageous in terms of space saving. Although not as much as the bottom layer where the main board unit 6 is located, even the middle layer where the power supply board 7 is located has a certain amount of extra space due to the slope. Therefore, it is possible to use the space between the power supply board and the inside of the chassis to bundle and arrange cables. Also, as described above, since the four skirt portions 51, 51, 51, 51 provided at the extension positions on the bottom sides of the front, back, and both side surfaces of the housing have cutouts, the routing of the connected cords is good. Further, for maintenance inspection, when accessing the main board unit 6 or the power supply board unit 7, since the first display portion 1 is provided on the front side and the second display portion 2 is provided on the back side, it is possible to access these board units just by removing the side cover member. Furthermore, it is also possible to remove the board unit for replacement. In short, the liquid crystal does not interfere with the replacement of the board unit or the like. Also, when inserting and removing cords with respect to the interface connector IF or detaching an external memory such as an SSD with respect to the expansion connector, it is not necessary to remove the liquid crystal. This is the effect achieved by the presence of space in the vertical and horizontal as well as front and back positions and the rotation of the display portion.

[0016] The data processing apparatus 100 according to an embodiment of the present invention is devised to have good accessibility to built-in components such as a main board unit, a power supply board unit, and a printer so that maintenance such as maintenance inspection and replacement of various components can be efficiently performed. Hereinafter, each component will be described.

[0017] (Regarding replacement of the main board unit) FIG. 3 is a partial perspective view showing the attachment / detachment structure of the main board unit. FIG. 4 is a side view of the data processing apparatus according to an embodiment of the present invention with the side cover member removed and further with the main board unit removed, where (a) shows a right side view and (b) shows a left side view.

[0018] As described above, when the left side cover member 3 and the right side cover member 4 on both sides of the housing are removed, the main board unit 6 and the power supply board unit 7 are exposed. The main board unit 6 is arranged on the lowermost layer of the third layer. As shown in FIGS. 3 and 4(b), in the internal structure IB of the housing on the side where the left side cover member 3 is removed, main board fixing screw holes 61, 61 as tapping holes are provided so as to be located inside the main board unit 6. Screws 61S, 61S are inserted through the insertion holes provided in the main board unit 6 and are fixed by screwing. That is, the main board unit 6 can be attached and detached on the left side of the housing. As will be described later, the power supply board unit 7 is also configured to be attached and detached on the left side of the housing. However, when removing the main board unit 6, it is not necessary to remove the power supply board unit 7. The two are configured to be attached and detached independently of each other. Also, since the first display unit 1 is provided on the front side and the second display unit 2 is provided on the back side, the liquid crystal does not get in the way either.

[0019] For the installation of the main board unit 6, from the state shown in FIG. 3, when the main board unit 6 is inserted into the internal structure IB of the housing by about 1 / 3, a plurality of wires to be connected (for example, speaker wires, etc.) are arranged in an appropriate vertical arrangement and then connected to a predetermined connector. Next, the main board unit 6 is inserted all the way to engage with the engaging portion arranged on the inner side. When the main board unit 6 is inserted all the way, the main board fixing screw holes 61, 61 and the insertion holes provided in the main board unit 6 are in the same concentric position, so the fixing is completed by screwing with the screws 61S, 61S. The removal is performed in the reverse procedure. Note that the fixing on the inner side (right side) has a function only of hooking, but the fixing on the inner side (right side) may also be by screws. In that case, the right side cover member 4 also needs to be removed when the main board unit 6 is detached, but the fixing mode becomes more firm. On the contrary, the present embodiment places more emphasis on the work efficiency that the main board unit 6 can be replaced only by removing the left side cover member 3.

[0020] (Regarding the replacement of the power supply board unit) Figure 5 is a partial perspective view showing the detachable structure of the power supply board unit. Figure 6 is a side view of the data processing device according to an embodiment of the present invention with the side cover member removed and the power supply board unit removed, where (a) is a right side view and (b) is a left side view.

[0021] The power supply board unit 7 is located in the middle layer of the three layers. As shown in Figures 5 and 6(b), the internal structure IB of the housing on the side where the left side cover member 3 is removed has screw holes 71, 71 for fixing the power supply board, which are tapped holes located inside the power supply board unit 7. Screws 71S, 71S are inserted through the insertion holes provided in the power supply board unit 7 and secured with screws. In other words, the power supply board unit 7 can be installed and removed from the left side of the housing. Note that it is not necessary to remove the main board unit 6 when removing the power supply board unit 7. The two are configured to be installed and removed independently of each other. Also, since the first display unit 1 is located on the front side and the second display unit 2 is located on the back side, the liquid crystal does not get in the way.

[0022] To install the power supply board unit 7, from the state shown in Figure 5, insert the power supply board unit 7 all the way into the internal structure IB of the housing and engage it with the engaging part located at the rear. Once the power supply board unit 7 is inserted all the way in, the screw holes 71, 71 for fixing the power supply board and the insertion holes provided in the power supply board unit 7 will be concentric, and the unit can be fixed by screwing it in with screws 71S, 71S. Removal is done in the reverse order. Note that the fixing at the rear (right side) is provided by an engaging part that only has the function of a simple catch, but fixing at the rear (right side) may also be done with screws. In that case, it would be necessary to remove the right side cover member 4 when attaching or detaching the power supply board unit 7, but the fixing method would be more secure. In contrast, this embodiment places more emphasis on work efficiency, as the power supply board unit 7 can be replaced by removing only the left side cover member 3. When inserting the power supply board unit 7, it is necessary to connect several wires, such as power lines and communication lines, to the designated connectors. However, since there are not enough wires to connect to the main board unit 6, it is sufficient to make the necessary connections once the board is inserted to an appropriate position.

[0023] (Regarding printer replacement) Figure 7 is a partial perspective view showing the printer attachment / detachment structure. Figure 8 is a side view of the data processing device according to an embodiment of the present invention with the side cover member removed and the printer removed, where (a) is a right side view and (b) is a left side view.

[0024] The printer 8 is positioned at the top of the three layers. As shown in Figures 7 and 8(a), the internal housing structure IB on the side where the right side cover member 4 is removed has screw holes 81 for fixing the printer, which are tapped holes located on the inside of the printer 8. The printer 8 is fixed by inserting screws 81S through holes provided in the legs of the printer 8 and then screwing them in. In other words, the printer 8 can be installed and removed from the right side of the housing. When removing the printer 8, it is not necessary to remove the main board unit 6 or the power supply board unit 7. The three elements are configured to be installed and removed independently of each other.

[0025] To install the printer 8, insert it into the internal structure IB of the housing from the right side until it is fully inserted and engage with the engagement part located at the rear. Once the printer 8 is fully inserted, the screw holes 81 for fixing the printer (which act as tapped holes) and the insertion holes provided in the printer 8 become concentric, and the printer is then secured with screws 81S. After that, the necessary cables are connected to the USB port, etc., and the fixing is complete. Removal is done in the reverse order. Note that the fixing on the rear (left) side is provided by an engagement part that only functions as a catch, but the fixing on the rear (left) side may also be done with screws. In that case, it would be necessary to remove the left side cover member 3 when attaching or detaching the printer 8, but the fixing method would be more secure. In contrast, this embodiment prioritizes work efficiency, as the printer 8 can be replaced by removing only the right side cover member 4. Furthermore, the printer 8 may be configured to be screw-fixed only on the left side instead of the right side. In this case, the main board unit, power supply board unit, and printer can all be accessed from the left side, further improving work efficiency. In this embodiment, the top surface of the printer unit also serves as the top surface of the housing, and the operating member for opening the top surface is located on the right side, resulting in a configuration where attachment and detachment are performed from the right side. However, if a printer with the operating member located on the left side is used, the attachment and detachment direction will naturally be to the left. Furthermore, unlike the main board unit 6 located at the bottom and the power supply board unit 7 located in the middle layer, the printer 8 located at the top layer can also be configured for attachment and detachment from the top. Even with such a configuration, the problem of improving work efficiency during maintenance is fully solved.

[0026] As described above, the data processing device 100 according to the embodiment of the present invention allows easy access to the main board unit 6, power supply board unit 7, and printer 8 simply by removing the left side cover member 3 and the right side cover member 4, and enables easy installation, removal, and replacement of these components. Furthermore, in the modified configuration shown, it is possible to perform maintenance by removing only one side cover member. Conventional POS registers require a certain amount of workspace during maintenance, such as removing the front or rear cover, which necessitates moving the device from its installation location and performing the work elsewhere. Naturally, this also results in longer maintenance times. For data processing devices such as POS registers, minimizing device downtime is a crucial issue, and the improved work efficiency of this embodiment contributes significantly to this.

[0027] (Regarding the structure of the bottom of the enclosure suitable for the lowest-level placement of the main board unit) Since the main board unit 6 is located on the bottom layer of the third layer, the interface connector IF is located in the area below the connection part to which the second display unit 2 is connected, as shown in Figure 3 (see also Figure 1(b), where part of the terminal part is visible through the cord communication hole 52 provided on the bottom surface 5 of the housing).

[0028] As shown in Figures 1(a) and 1(b), the data processing device 100 according to the embodiment of the present invention is provided with four skirt portions 51, 51, 51, 51 at the extensions of the bottom sides of the front, back, and both sides of the housing. Here, the skirt portions 51, 51, 51, 51 on the front, back, and both sides have notches. In addition, a cord passage hole 52 is provided on the bottom surface directly below where the interface connector IF is located, and the cord can be passed through any of the aforementioned notches to the outside of the data processing device 100. With this configuration, the cord can be routed neatly around the data processing device 100.

[0029] As mentioned above, there are four notches on the front, back, and both sides. In particular, the notch on the back is convenient for routing the cord that extends downward through the cord passage hole 52 provided on the bottom surface 5 directly below where the interface connector IF is located. There do not necessarily have to be four notches; for example, the front side may be a skirt without a notch. However, in this embodiment, since the power connector 53 for plugging in the power cord is located near the front of the bottom surface, the notch on the front side can also be effectively utilized.

[0030] (Regarding the structure suitable for attaching and detaching accessories) The data processing device 100 according to an embodiment of the present invention also includes an accessory device, specifically, in this example, an advantageous configuration that allows for easy attachment and detachment of an SSD memory, particularly removal. Conventionally, while it is relatively easy to insert an SSD memory into an expansion connector and firmly connect it, the tighter the connection, the more difficult it is to pull it out. If the SSD memory is forcibly pulled out in an unstable position, the terminal portion may be damaged. This embodiment is designed to appropriately address such problems.

[0031] Figure 9 is a front view of a data processing device according to an embodiment of the present invention with the first display unit and expansion connector unit cover removed. Figure 10 is a downward perspective view showing the removal of an accessory device from the expansion connector unit, with Figure 10(a) showing the initial stage of the removal operation and Figure 10(b) showing an intermediate stage of the removal operation. Figure 10(c) is an enlarged view of part A in Figure 10(a).

[0032] An expansion connector for connecting SSD memory is provided in the area below the connection section to which the first display unit 1 is connected. In Figure 9, the first display unit 1 is not shown for clarity, but in reality, as can be seen in Figures 1 and 2, the arrangement allows access to the cover of the expansion connector by changing the angle of the first display unit 1.

[0033] As shown in Figure 9, the SSD memory, which is the accessory device AE, is loaded into an expansion connector located at the back, which is not shown. The expansion connector is provided in the internal housing structure IB of the data processing device 100, and the expansion connector and the main board unit 6 are connected by a cable. The data processing device 100 also has a housing side plate 9 for screw fastening the SSD memory, which is the accessory device AE, and the accessory device AE has an accessory side plate 9A for screw fastening to the data processing device 100. In Figure 9, the housing side plate 9 is hidden because the accessory side plate 9A is located at the front, but from Figure 10(c), it can be seen that the housing side plate 9 is located behind the accessory side plate 9A.

[0034] The housing side plate 9 has fixing screw holes 91 sized to match the outer diameter (nominal diameter) of the screw threads, and the accessory device side plate 9A has fixing through holes 9A1 at corresponding positions to the fixing screw holes 91, with a size greater than or equal to the outer diameter (nominal diameter) of the screw threads but less than the diameter of the screw head. In Figure 9, the accessory device side plate 9A is positioned at the front and screws are also depicted, but the fixing screw holes 91 and the fixing through holes 9A1 are concentric. Naturally, the fixing screw holes 91 are tapped holes.

[0035] The method of attaching the SSD memory to the data processing device 100 by inserting screws through the fixing screw holes 91 and fixing through holes 9A1 is a common method using screws. However, this embodiment has a distinctive configuration for removing the SSD memory, which is an accessory device AE. It is physically possible to pull the SSD memory out of the expansion connector by releasing the screw fixing. However, in actual operation, problems such as damage to the connection part can occur if the SSD memory is not pulled out straight while maintaining a orientation facing the expansion connector. On the other hand, it is difficult to pull out two components that have been firmly fixed together by screws in a straight line.

[0036] Therefore, the data processing device 100 according to an embodiment of the present invention has a screw hole 9A2 for disconnecting the connection by the expansion connector at a different location from the fixing through hole 9A1. The screw hole 9A2 for disconnecting is a tapped hole sized to match the outer diameter (nominal diameter) of the screw. Furthermore, there is no hole in the position corresponding to the screw hole 9A2 on the housing side plate 9. As a result, when a screw is inserted into the screw hole 9A2 and screwed in, the tip of the screw abuts against the housing side plate 9, and as the screw continues to be driven in, the side plate 9A of the attached device is pushed forward by the pressure of the screw. Along with this movement, the SSD memory is naturally removed from the expansion connector.

[0037] In this embodiment, the screw holes 91 for fixing the housing side plate 9 and the screw holes 9A2 for disconnecting the attachment side plate 9A have the same screw size. Therefore, the screws removed from the fixing screw holes 91 can be used as is for inserting and removing the SSD memory. Of course, to increase the pressing force, the screw size of the screw holes for disconnecting the attachment may be increased, or a dedicated screw size may be used.
