Japanese Unexamined Patent Publication No. 10-333715

When installing the information processing device as described above, the installation posture of the housing can be either a vertical posture or a horizontal posture, and in many cases, it can be freely selected depending on the installation space and the like. However, the character display arranged in the housing is either an upright display in the vertical position or an upright display in the horizontal position. In other words, when an information processing device equipped with a number display that displays upright in the vertical position is installed in the horizontal position, the numbers (error code, status information, etc.) displayed on the character display are displayed overturned. There was a problem that it was difficult to recognize. A similar problem occurs when an information processing device equipped with a number display that displays upright in a horizontal position is also installed in a vertical position. Further, when both the display for the vertical posture and the display for the horizontal posture are installed, the cost is increased and one of them is not used, which is not economical.

The present invention can be realized by a configuration other than the configurations disclosed in the following embodiments, and at least one of various effects based on the basic configuration and derivative effects can be obtained. ..

FIG. 1 is a front view showing an information processing device (for example, a personal computer: PC) 10 according to the present embodiment. The information processing device 10 is not limited to a PC, and may be an electronic device that executes arithmetic processing in a built-in processing unit.

As shown in FIG. 1, the information processing device 10 is, for example, a stationary computer. The information processing device 10 has a housing 12. Inside the housing 12, for example, a main information processing unit and a plurality of sub information processing units, each of which has a processor, are housed in a state of being communicably connected via a relay device. In addition, a power supply unit or the like that supplies power to each processing unit is housed. The information processing device 10 is, for example, a central processing unit (CPU), a random access memory (RAM), a motherboard (M / B), various circuit boards such as a daughter board, a hard disk drive (HDD), or a solid state. It may be a general PC provided with a recording device such as a drive (SSD), a power supply unit, and the like.

The housing 12 has a front cover 14. The front cover 14 covers the inside of the housing 12. The front cover 14 is made of, for example, synthetic resin or metal. In this specification, the X direction, the Y direction, and the Z direction are defined. The X direction is the lateral direction (width direction) of the front cover 14 (housing 12) in FIG. 1, and the Y direction is the longitudinal direction (height direction) of the front cover 14 (housing 12) in FIG. ). The Z direction is the depth direction of the front cover 14 (housing 12). Further, in the present specification, the information processing apparatus 10 (housing 12) shown in FIG. 1 is allowed to be placed vertically or horizontally with a predetermined surface (for example, the front cover 14) facing in one direction. NS. That is, a posture in which one of the facing edges 10A of the front cover 14 extending in the X direction is parallel to the installation surface G is referred to as a "vertical posture". Further, a posture in which any one of the facing edges 10B of the front cover 14 extending in the Y direction is parallel to the installation surface G is referred to as a "horizontal posture".

For example, an alternator operation type power switch 16 is provided on the surface of the front cover 14. Further, on the outer edge of the power switch 16, a power indicator lamp 18 that lights up when the power of the information processing device 10 is ON is arranged. The power indicator lamp 18 is lit by a light source such as a light emitting diode (LED). The position of the power indicator 18 is not limited to the periphery of the power switch 16, and may be arranged as an independent indicator in the vicinity of the power switch 16, or may be arranged on the operation surface of the power switch 16. May be good. When the power indicator lamp 18 is arranged on the operation surface of the power switch 16, for example, the power mark formed on the surface of the power switch 16 may be lit.

Further, on the outer edge of the housing 12, for example, a tube-shaped state display unit 20 that lights up in conjunction with the power indicator lamp 18 is arranged. The state display unit 20 is composed of, for example, a light source, a light guide tube, and a diffusion member. The light source is, for example, an LED. The light guide pipe is, for example, a rod-shaped component made of a flexible, substantially columnar synthetic resin that is substantially transparent and capable of transmitting light. The light guide tube transmits the light emitted by the light source arranged at one end toward the other end. Therefore, when the light source emits light, the entire light guide tube appears to emit light. The diffusion member is arranged so as to cover the surface side of the light guide tube. The diffusing member is, for example, a milky white component formed of a synthetic resin such as polycarbonate and capable of transmitting light, and diffuses the light incident from the light guide tube and emits it to the surface side. Therefore, the diffusion member makes the state display unit 20 appear to emit light substantially uniformly as a whole. If the state display unit 20 includes LEDs having a plurality of light emitting colors, the state display unit 20 can emit light in a light emitting color according to the state of the information processing device 10. For example, the status display unit 20 can display "blue" or "green" as the display color when the information processing device 10 operates normally. Further, "orange", "red", or the like can be displayed as a display color when an error occurs in the information processing device 10. The power indicator lamp 18 can also be turned on with the same configuration. Further, the power indicator lamp 18 and the status display unit 20 can display the lighting state as well as the blinking state.

In the vicinity of the power switch 16, a code display unit 22 is arranged as a display unit for displaying state information (for example, a state code) indicating the state of the processing unit housed in the information processing device 10. The code display unit 22 is, for example, as shown in FIG. 2, a matrix display device in which a plurality of point light sources 24 (for example, LEDs) are arranged in a matrix. In the case of FIG. 2, the code display unit 22 includes a square display area composed of 11 point light sources 24 in each of the vertical and horizontal directions. That is, the maximum number of vertically arranged points and the maximum number of horizontally arranged point light sources 24 arranged in a matrix of the code display unit 22 are the same. The code display unit 22 can individually turn on or off the point light sources 24 arranged in a matrix, and can realize the display of numbers, symbols, or characters by the combination thereof. For example, when it is detected that an error has occurred in the processing unit accommodated in the information processing device 10, the code display unit 22 shows an error code (state) indicating information for identifying the platform on which the error has occurred and the content of the error. Code) is displayed. The error code is displayed as, for example, a number, an alphabet, or a symbol. The user can easily grasp the state (error state) of the processing unit based on the error code displayed on the code display unit 22. Then, detailed verification based on the error code can be performed. The number of arrangements and arrangement form of the point light sources 24 in the code display unit 22 will be described later.

As shown in FIG. 1, the front cover 14 of the housing 12 may be provided with a power switch 16, a code display unit 22, and a connection terminal 26 used for electrically connecting an external device. .. As long as the device arranged on the front cover 14 includes the code display unit 22, the device is not limited to the configuration shown in FIG. 1, and can be appropriately increased or decreased according to the specifications of the information processing device 10.

FIG. 3 shows a state in which a state code (for example, an error code 22a) as state information displayed on the code display unit 22 is displayed upright when the information processing device 10 is arranged in a vertical position. There is. Here, the upright display is a state in which the top and bottom are correctly displayed without the error code 22a falling over when the user is present and viewed substantially in front of the installed information processing device 10. Is. In FIG. 3, the error code 22a is an example in which two elements "E" and "R" are arranged side by side in the X direction and are shown by two digits that can be recognized as "ER".

By the way, when the display state of the code display unit 22 remains as shown in FIG. 3 (the two elements "E" and "R" remain side by side in the X direction), the information processing device 10 is changed to the horizontal posture (for example). ), When rotated 90 ° counterclockwise), the error code 22a is displayed as a fall. That is, the characters "E" and "R" are oriented sideways, and "E" and "R" are stacked in the X direction, which makes the display difficult to recognize. Therefore, the code display unit 22 of the present embodiment changes the display posture of the code display unit 22 based on the posture of the information processing device 10 (housing 12). That is, when the housing 12 is in the horizontal posture, the error code 22a displayed on the code display unit 22 has two elements "E" and "R" arranged side by side in the Y direction, and faces 10 in the horizontal posture. It is indicated by two digits so that the user can recognize it as "ER". The power indicator lamp 18 and the status display unit 20 do not display numbers, symbols, characters, etc. whose vertical and horizontal directions are easily recognized. Therefore, regardless of whether the information processing device 10 is in the vertical position or the horizontal position, necessary information, for example, information on whether the processing unit is operating normally or the power switch 16 is turned on. Information and the like can be recognized by the user.

FIG. 5 is an exemplary and schematic diagram showing the hardware configuration of the information processing device 10. The information processing device 10 includes a relay device 28 (bridge board) and an LED board 30 as a configuration necessary for explaining the present embodiment.

The relay device 28 includes, for example, a PCIe (Peripheral Component Interconnect Express; registered trademark) bridge controller 32, a processor 34, a plurality of PCIe slots 36 for an information processing unit, a power supply slot 38 for a power supply unit, and a voltage step-down. Converters 40a and 40b, LED connectors 42a and the like are mounted. Further, the LED board 30 is equipped with a matrix LED controller 44, an acceleration sensor 46, an RGB LED controller 48, a status display unit 20 (LED), a code display unit 22, a power switch 16, an LED connector 42b, and the like.

The PCIe bridge controller 32 controls communication between, for example, a main information processing unit (main platform 50) and a plurality of sub information processing units (first platform 52-1 to sixth platform 52-6). In the example shown in FIG. 5, the first platform 52-1 to the sixth platform 52-6 are connected to the first PCIe slots 36-1 to the sixth PCIe slots 36-6 formed in the relay device 28, respectively. ing. Further, the main platform 50 is connected using two PCIe slots, a 7th PCIe slot 36-7 and an 8th PCIe slot 36-8. Although FIG. 5 shows an example in which the information processing device 10 has eight PCIe slots (first PCIe slots 36-1 to eighth PCIe slots 36-8), the information processing device 10 has a plurality of platforms. Any configuration may be used as long as it can be connected, and the configuration is not limited to the form provided with eight PCIe slots.

The main platform 50 and the first platform 52-1 to the sixth platform 52-6 are devices each including a processor that executes various processes. The main platform 50 is, for example, a host PC that functions as a control unit of the information processing device 10 and a GUI (Graphical User Interface). Further, the first platform 52-1 to the sixth platform 52-6 are arithmetic units that execute, for example, AI (Artificial Intelligence) inference processing, image processing, and the like. In the present embodiment, the PCIe bridge controller 32 connects the main platform 50 and the first platform 52-1 to the sixth platform 52-6 via the PCIe bus L1, and executes high-speed communication with each other using the PCIe. ing.

The processor 34 controls the entire PCIe bridge controller 32. Then, the processor 34 executes the software program stored in the memory to transfer data between the platforms in the PCIe bridge controller 32 (between the processors of the main platform 50 and the first platform 52-1 to the sixth platform 52-6). To realize. In addition, when it is detected that an error has occurred on the main platform 50 or the first platform 52-1 to the sixth platform 52-6, or between the main platform 50 and the first platform 52-1 to the sixth platform 52-6. When it is detected that a communication abnormality has occurred, a signal indicating the abnormality is provided to the processor 34 via a signal line L2 connected to a dedicated terminal such as GPIO (General Purpose Input Output). The processor 34 can store the state of each platform, for example, the activation status of the application and the information of the error generated in each platform in the storage unit, and the light emitting mode of the power indicator light 18 and the status display unit 20 and the code display. It can be reflected in the display mode of the unit 22.

A power supply unit that supplies power to the relay device 28 and the LED board 30 is connected to the power supply slot 38. Power supply unit, the backup power voltages V ₁ to be constantly supplied regardless of the state of the power switch 16, it is possible to output the drive power supply voltage V ₂ to be supplied only when the power switch 16 is ON. Further, the converter 40a that steps down supplies a step-down constant voltage V _{11 that steps down the constant power supply voltage V 1} to a predetermined voltage to the processor 34 and the LED board 30 side. Similarly, the converter 40b that steps down supplies a step-down drive voltage V _{21 that steps down the drive power supply voltage V 2} to a predetermined voltage to the main platform 50, the first platform 52-1 to the sixth platform 52-6, and the like.

The relay device 28 and the LED board 30 are connected by an LED connector 42a and an LED connector 42b. By connecting the LED connector 42a and the LED connector 42b, the LED board 30 receives the step-down constant voltage V ₁₁ and sends and receives signals via the signal line L2 connected to a dedicated terminal such as GPIO. do.

The matrix LED controller 44 controls the lighting of each point light source 24 of the code display unit 22 based on the control signal provided by the processor 34. Similarly, the RGB LED controller 48 controls the lighting of the light source (for example, LED) of the status display unit 20 based on the control signal provided from the processor 34. The acceleration sensor 46 acquires acceleration information for discriminating the posture (vertical posture and horizontal posture) of the housing 12 and provides the acceleration information to the processor 34. Matrix LED controller 44, an acceleration sensor 46, an RGB LED controller 48 and the processor 34, for ^example, by serial communication, such as ^I 2 C (R), is performed transmission and reception of signals via a signal line L3. _{A step-down constant voltage V 11} is constantly provided to the point light source 24 of the code display unit 22, the LED of the status display unit 20, and the like, so that light can be emitted at any time.

FIG. 6 is an exemplary and schematic block diagram showing a configuration for realizing control of the code display unit 22 in the processor 34. The processor 34 realizes modules such as an acquisition unit 34a, a determination unit 34b, and a display control unit 34c by executing a software program stored in the memory.

The acquisition unit 34a acquires the acceleration information detected by the acceleration sensor 46. Further, the acquisition unit 34a is in an operating state on each platform (main platform 50 or first platform 52-1 to sixth platform 52-6), for example, whether or not it has started, and whether or not there is an error (internal error, peripherals such as a fan, etc.). Acquire information such as whether or not the device is driven. In the present embodiment, as an example of the posture information indicating whether the housing 12 is installed in the vertical posture or the horizontal posture, the acquisition unit 34a has described an example in which the acquisition unit 34a acquires the acceleration information. Information other than acceleration information may be used as long as the information can determine the posture of the body 12.

The determination unit 34b determines whether the posture of the housing 12 is the vertical posture or the horizontal posture based on the acceleration information acquired by the acquisition unit 34a. Further, the determination unit 34b determines the direction of change when the posture is changed, for example, whether the posture is rotated by 90 ° to the left or right from the vertical posture to be in the horizontal posture. The determination unit 34b can determine, for example, the posture and rotation direction of the housing 12 (information processing device 10) with reference to the direction of gravity.

The display control unit 34c is based on the operating state of each platform (main platform 50 and the first platform 52-1 to the sixth platform 52-6) acquired by the acquisition unit 34a, and the presence / absence of display of the code display unit 22 and the code. When displaying the display unit 22, the display content, for example, the type of the error code 22a is determined. Then, when the display control unit 34c displays the code display unit 22, the code display unit 22 is based on the posture and rotation direction of the housing 12 determined by the determination unit 34b and the content of the error code 22a to be displayed. The point light source 24 to be turned on is determined, and a lighting control signal is output.

In FIG. 7, the horizontal direction that coincides with the horizontal direction (X direction) of the housing 12 (front cover 14) is the X direction, and the vertical direction that coincides with the vertical direction (Y direction) of the housing 12 (front cover 14). Is shown in the code display unit 22 in the Y direction. FIG. 7 shows the arrangement of the point light sources 24 in the code display unit 22, the vertical display area 54 used when the housing 12 is in the vertical position, and the horizontal display area 56 used when the housing 12 is in the horizontal position. The position (non-used area 58) where the unused point light source 24, which is not used in any of the postures, exists is shown.

The code display unit 22 displays one element (for example, when the state information (error code 22a) is displayed upright, that is, when the user sees the error code 22a from the front and the display is easy to recognize. , Numbers, letters, alphabets, etc.), it has been confirmed by tests and the like that it is desirable to use a display area of at least 7 dots vertically and 5 dots horizontally in consideration of visibility (element resolution). Further, when displaying a plurality of elements side by side, it has been confirmed by tests and the like that it is desirable to leave one line of dots between the elements in the arrangement direction (blank area). Therefore, when displaying the two-element error code 22a on the code display unit 22, the minimum number of arrangements of the point light sources 24 is 7 dots in the vertical direction and 5 dots + 1 dot in the horizontal direction + 5 dots = 11 dots.

As shown in FIG. 7, a code display in which the vertical Y direction and the horizontal X direction of the housing 12 (front cover 14) and the vertical direction (Y direction) and the horizontal direction (X direction) coincide with each other. First, consider a case where the code display unit 22 displays the error code 22a when the housing 12 is installed in the vertical position in the unit 22. In this case, the two-element error code 22a is displayed using the vertical display area 54 having 7 dots vertically and 11 dots horizontally. FIG. 8 is an example in which the error code 22a of “01” is displayed in the vertical display area 54. Therefore, the display control unit 34c turns on and off the light source 24 at each point so as to form "01". In this case, the error code 22a displayed on the code display unit 22 is displayed upright as in the example shown in FIG. 3, and when the user sees it from the front, the error code 22a is easily "01". Can be recognized.

Next, consider a case where the code display unit 22 shown in FIG. 7 displays the error code 22a on the code display unit 22 when the housing 12 is installed in the horizontal position. In this case, the two-element error code 22a is displayed using the horizontal display area 56 having 11 dots vertically and 7 dots horizontally. FIG. 9 is an example in which the error code 22a of “23” is displayed in the vertical display area 54. Therefore, the display control unit 34c turns on and off the light source 24 at each point so as to form "23". In this case, the code display unit 22 is displayed in a state where the housing 12 (information processing device 10) is rotated 90 ° counterclockwise, so that the error code 22a is the same as the example shown in FIG. , In the horizontal posture, the display is upright, and when the user sees it from the front, the error code 22a of "2 3" can be easily recognized.

That is, the display control unit 34c makes an error based on the posture of the housing 12 so that the error code 22a to be displayed on the code display unit 22 is displayed upright regardless of whether the housing 12 is in the vertical or horizontal posture. The code 22a is displayed and controlled. As a result, an information processing device including a code display unit 22 capable of displaying an error code 22a such as a number in an easily recognizable state regardless of whether the housing 12 is installed in a vertical position or a horizontal position. 10 can be provided.

Further, the display control unit 34c may perform display based on the operating state of each platform (main platform 50 or first platform 52-1 to sixth platform 52-6) acquired by the acquisition unit 34a. For example, when the acquisition unit 34a acquires the information that an error has occurred in any one of the platforms, the display control unit 34c controls the display of the information that identifies the platform in which the error has occurred. As the information for identifying the platform on which the error has occurred, for example, the slot number to which the platform is connected can be considered. In this case, the display control unit 34c performs display control with "S 3" (slot number 3). Even when the display control is performed, an upright display is performed according to the posture of the housing 12. By displaying the information that identifies the platform on which the error has occurred, the user can recognize the platform on which the error has occurred.

In the example of FIG. 7, an example in which the error code 22a is displayed by two elements is shown, but the number of elements to be displayed may be two or more elements. The types of error codes 22a that can be displayed increase according to the number of elements. In this case, it is necessary to be able to display the same error code 22a in the vertical posture and the horizontal posture. That is, the maximum number of vertically arranged points and the maximum number of horizontally arranged point light sources 24 arranged in a matrix of the code display unit 22 are the same. Therefore, the code display unit 22 is formed in a square shape regardless of the number of elements (number of digits) to be displayed. As a result, it is possible to maintain the same aspect ratio of the elements to be displayed in the vertical posture and the horizontal posture, and even if the posture of the housing 12 is changed, the display can be performed without discomfort. .. In this case, assuming that the number of elements to be displayed is K, the maximum number S of the vertical and horizontal arrangements of the point light sources 24 in the code display unit 22 is indicated by S = 5 × K + (K-1). Therefore, the code display unit 22 provided with the minimum necessary point light source 24 can be easily designed.

By the way, as described above, the vertical display area 54 is used when the code display unit 22 is displayed in the vertical position, and the horizontal display area 56 is used when the code display unit 22 is displayed in the horizontal position. Will be done. Therefore, as shown in FIG. 7, the code display unit 22 is not used in either of the cases where the error code 22a is displayed in the vertical position and the error code 22a is displayed in the horizontal position. There is a point light source 24 at a position. Therefore, the unused point light source 24 can be omitted from the code display unit 22. For example, in the case of the code display unit 22 shown in FIG. 7, 4 dots at the four corners, 16 dots in total, are unused (non-used area 58). Therefore, in the case of the 11 × 11 dot code display unit 22 of FIG. 7, the point light source 24 of 11 × 11 − (4 × 4) = 105 dots is used to display the display in the vertical position and the display in the horizontal position. can do. In the code display unit 22, the number of vertical and horizontal dots R of the unused area 58 of the point light source 24 that can be non-arranged (omitted) is K, and the number of elements displayed in the code display unit 22 is K, and the vertical display area. Assuming that the number of horizontal dots of 54 (or the horizontal display area 56) is A and the number of vertical dots is B, it can be calculated by R = | AB | / K. That is, in the case of the code display unit 22 shown in FIG. 7, R = | 11-7 | / 2 = 2, each unused area 58 is 2 × 2 = 4 dots, and a total of 4 × 4 = 16 dots. Can be omitted.

That is, when designing the code display unit 22 that can handle both the vertical posture and the horizontal posture, the size of the code display unit 22 and the point light source 24 constituting the code display unit 22 are based on the number of elements to be displayed. The number can be easily grasped, and the design of the code display unit 22 can be simplified.

As described above, according to the information processing apparatus 10 of the present embodiment, the display control unit 34c erects the error code 22a displayed on the code display unit 22 regardless of whether the housing 12 is in the vertical or horizontal posture. The error code 22a is displayed and controlled based on the posture of the housing 12 so as to be displayed. As a result, the error code 22a such as a number can be displayed in an easily recognizable state regardless of whether the housing 12 is installed in the vertical position or the horizontal position.

Further, by making the maximum number of vertical arrangements and the maximum number of horizontal arrangements of the point light sources 24 arranged in a matrix of the code display unit 22 the same, the code display unit 22 is irrespective of the number of elements (digits) to be displayed. It is formed in a square shape. As a result, it is possible to maintain the same aspect ratio of the elements to be displayed in the vertical posture and the horizontal posture, and it is possible to display without discomfort even if the posture is changed.

Further, by configuring the code display unit 22 to display two or more elements of numbers, symbols, or characters as the state information, the type of error code 22a can be easily selected regardless of the vertical posture or the horizontal posture. Can be increased to.

Further, in the information processing apparatus 10, the point light sources 24 at positions that are not used in either of the vertical postures and the horizontal postures are not arranged, thereby reducing the cost. Can contribute.
