[0016] The embodiments of the present invention will be described below, with the use of drawings as necessary. For ease of understanding, the descriptions will be divided into external features, internal structural features, functional block features, operation flow features, and screen display features, and will be explained sequentially.

[0017] Each feature, even individually, constitutes an independent technical concept and falls within the scope of the patent claims of this application. Furthermore, by combining various features, it is possible to provide users with a sensor checker that offers improved convenience. Therefore, it is even more desirable to combine multiple features. However, this is not limited to cases where multiple features are combined. [Examples]

[0018] This embodiment describes the external features of an example of a sensor checker.

[0019] Figures 1A to 1E are schematic external views of an example of a sensor checker. Figure 1A is a schematic front view, Figure 1B is a schematic top view, Figure 1C is a schematic bottom view, Figure 1D is a schematic left side view, and Figure 1E is a schematic right side view.

[0020] The explanation will begin with the schematic front view in Figure 1A. The sensor checker 10 has a housing that is roughly rectangular in shape, with a longitudinal direction and a transverse direction. It is divided into a sensor connection part 10B and a main body part 10A along the longitudinal direction, and these are joined together to form a single unit. In this specification, the term "roughly rectangular" includes not only rectangular shapes but also shapes that can be considered substantially rectangular. Specifically, as shown in Figures 1A to 1E, Figures 8A to 8E, and Figure 9, shapes with rounded corners or small irregularities on the surface that can be considered generally rectangular in shape as a whole are also included in the definition of roughly rectangular. The longitudinal direction and transverse direction correspond to the vertical and horizontal directions in Figure 1A, respectively.

[0021] The sensor connection section 10B is provided with a sensor connector 30 to which a sensor is connected. A sensor connector is also called a terminal block or terminal for connection, and examples include M12 connectors and bare wire connection terminals. Note that the example of them being joined and integrated is just one example; it also includes cases where the sensor connection section 10B and the main body section 10A are constructed as a single unit from the beginning. The sensors to be connected include various sensors such as photoelectric sensors and proximity sensors.

[0022] However, by making the sensor connector 10B and the main unit 10A separable, it becomes possible to handle various sensors simply by switching the sensor connector 10B. This means that the main unit 10A can be shared. Furthermore, users can obtain a sensor checker with different functions simply by replacing the sensor connector 10B, without having to buy a new main unit 10A. As a result, a low-cost sensor checker with improved user convenience can be realized.

[0023] The sensor checker 10 has a display 11 that displays information regarding input and output with the sensor connected to the sensor connector 30. The information regarding input and output with the sensor includes, for example, at least one of whether or not a trigger has been sent to the sensor, the detection status of the sensor signal, and the power supply status to the sensor.

[0024] The display 11 displays information regarding input and output to the sensor using text or graphic information. For example, the display 11 may display information regarding input and output to the sensor using only text, only graphic information, or both text and graphic information. The display color of the display may be grayscale.

[0025] When considering the replacement of the sensor connection unit 10B, the amount of information that needs to be displayed on the display 11 increases. Therefore, in order to accurately provide information to the user, a multi-functional display capable of displaying multiple colors and simultaneously displaying text and graphic information may be used, in addition to conventional monochrome displays, lamp displays, and displays of numbers and characters only. The display 11 can also detect the replacement of the sensor connection unit 10B and display in a different manner, or it can be manually switched between displays.

[0026] The sensor checker 10 has a sensor connector 30. As shown in Figure 1A, it is located on the upper side of the sensor checker. It is a connector for connecting wiring to an external device to be measured. There are no particular limitations on the type or number of connectors, but one that can handle four or more is desirable in order to accommodate a variety of measurement targets.

[0027] The sensor checker 10 has a grip portion 12. The presence of the grip portion 12 is not essential, but it is desirable for the reasons described below.

[0028] The sensor checker has a recessed grip portion 12 on the underside (the side with the USB connector) of the housing, below the display 11. The grip portion 12 is realized by slightly recessing, indenting, or reducing the thickness of a part of the main body 10A. The amount of recessing itself may be less than 1 mm. However, by recessing, indenting, or reducing the thickness of a part in this way, the ease of gripping the sensor checker when the user holds it is improved, and the effect of preventing the sensor checker from slipping from the user's hand and falling can be achieved. In addition, the display 11 is less likely to be obscured by the user's hand. In Figure 1A, the grip portion 12 is configured so that its width in the vertical direction decreases from the side toward the center.

[0029] The effect of this shape is that it guides the user to grip the device more towards the center than if the width were not constant. As a result, the grip becomes more secure, and it becomes possible to prevent damage to the display 11 due to inappropriate pressure applied during gripping. This is a desirable consideration because the display 11 is a multi-functional display and is a thin-film device such as a liquid crystal or OLED display.

[0030] Figure 1B is a schematic top view. It shows that the sensor connector 30 described in Figure 1A is located on the top side, which is one end face in the longitudinal direction of the housing of the sensor checker.

[0031] Figure 1C is a schematic bottom view. As a result of the inventors' consideration of user usage and environment in order to improve the convenience of the sensor checker, they concluded that it would be desirable to have a mobile battery function in addition to the sensor checker's multi-functionality. Therefore, the terminals and other components necessary to have a mobile battery function are mounted on the bottom surface, which is the other end surface in the longitudinal direction of the housing.

[0032] C1 and C2 are USB ports. While there are no specific restrictions on the USB port standard, USB-C ports, which are the de facto standard for current mobile devices, are preferred. The diagram shows two ports, but this is not limited to two. These USB-C ports can be used as power supply terminals for external devices as a mobile battery. They can also be used as charging terminals for the sensor checker's built-in battery.

[0033] LEDs are the external lighting components. While the term "LED" is used because LED elements are preferable due to their high light output and low power consumption, this does not exclude the use of other light-emitting devices.

[0034] Having an external LED light unit is a significant advantage for users of sensor checkers. That is, when using a sensor checker, the object being inspected by the user may not always be in an environment with sufficient light. One example is when using a sensor checker during inspections of existing equipment. In such cases, having a built-in lighting function in the sensor checker allows the user to obtain a sufficiently lit working environment without having to prepare other lighting devices. Therefore, it is possible to provide a sensor checker that improves user convenience.

[0035] Furthermore, it is preferable to position the LEDs towards one side. This is because it makes it easier to place larger LEDs in terms of the internal structure. Also, it helps to suppress the diffusion of heat generated by the LEDs into the interior through the physical structure.

[0036] By placing the LED on the bottom side opposite the top side where the sensor connector 30 is located, the convenience of using the LED while working with the sensor connector 30 can be improved. For example, it is possible to flip the bottom side 180 degrees to the top side to illuminate the LED.

[0037] Figure 1D is a schematic left side view. The sensor checker 10 has a connection bar 40. By operating this connection bar, the sensor connection part 10B and the main body part 10A can be separated and connected. Since this type of connection bar structure is widely used in consumer products such as shavers, a detailed description of the structure is omitted.

[0038] The sensor checker 10 has a left switch group 41. The left switch group has a distinctive arrangement; that is, a push switch is positioned between multiple slide switches.

[0039] Figure 2A shows an enlarged view of the area around the left switch group 41. A push-button switch is positioned between two slide switches. This structure allows the user to identify and operate the desired switch position by touch without having to visually check the switch's location. This means that the user's operating time when using the sensor checker will be reduced and work efficiency will be improved. Therefore, a sensor checker with improved user convenience can be provided by arranging a push-button switch between multiple slide switches.

[0040] The display 11 is positioned closer to the sensor connector 30 in the longitudinal direction. By separating the display 11 from the USB connectors C1 and C2, space can be secured for the USB circuitry near the USB connectors C1 and C2, enabling a tall and thin housing.

[0041] Figure 2A shows a push-button switch positioned between two slide switches. An example of the functional arrangement of each switch in this case is illustrated below.

[0042] The upper switch 41A is the power switch (also called the power switch). To prevent users from accidentally turning off the power while operating the sensor checker, or to prevent battery drain and depletion due to accidental operation, it is a slide switch that is less prone to accidental operation.

[0043] The central switch 41B is a trigger switch that controls the transmission of trigger signals to the sensor. For example, like an external trigger, it is a switch that allows the user to operate the sensor checker and output inspection signals, voltages, currents, etc., from the sensor connector 30 to external measurement targets or sensors. One example of a situation in which a user uses the sensor checker is when they need to sequentially check many measurement targets in a short amount of time. In such cases, if a slide switch is assigned, the operation will take time, worsening the user's work efficiency. Therefore, the sensor output switch, which may require multiple operations in some cases, is configured as a push-button switch.

[0044] The lower switch 41C is a buzzer switch. It allows the user to select whether or not to emit an audible alert based on the results of measuring an object using the sensor checker. This switch is also a slide switch designed to minimize accidental operation, thus preventing accidental audible alerts during work in environments requiring silence.

[0045] In this embodiment, to prevent malfunctions, a push-button switch is used during sensor checker operation (while the sensor is operating), and a slide switch is used before and after sensor checker operation (before the sensor is operating).

[0046] The text displayed in the diagram is in English as an example, but the type of language and its position are not particularly limited. Furthermore, the content of the display may also be subject to various changes.

[0047] Thus, the switch arrangement shown in Figure 1D or Figure 2A allows for the provision of a sensor checker that improves user convenience.

[0048] Furthermore, in the switch arrangement shown in Figure 1D or Figure 2A, each switch is positioned towards the right side of the figure. This means that they are positioned towards the front of the sensor checker. This arrangement further improves user convenience during operation. Also, as shown in Figure 3B later, if the circuit board 15 is positioned towards the front housing 17A side within the housing 17, connecting each switch to the circuit board 15 becomes easier.

[0049] The trigger switch (switch 41B) that controls the transmission of trigger signals to the sensor is located on the side of the housing, which is one end face in the shorter direction. Furthermore, it is preferable that the trigger switch is located closer to the sensor connector 30 in the longer direction of the housing. This configuration makes it easy to operate with one hand, as the trigger switch is close to the user's fingers when they hold the housing.

[0050] Figure 1E is a schematic right side view. The sensor checker 10 has a connection bar 40.

[0051] The sensor checker 10 has a right switch group 42. An LED lamp switch 45 is located below the right switch group 42, away from it. The LED lamp switch 45 is the switch that turns the LED in Figure 1C ON and OFF. Since it is a completely different type of switch from the sensor-related operation switches, it is located away from the right switch group 42 to facilitate identification. Furthermore, by being located on the grip portion 12, the user can easily locate it by touch. In addition, by configuring the switch as a push switch and making it more than twice the size of the lower switch 41 or the push switches in the right switch group 42, it is easier for the user to visually recognize and operate it in terms of area. In this embodiment, the switches are distributed on both sides of the housing by the left switch group 41 and the right switch group 42. If switches of similar shape are concentrated on one side, it is difficult to distinguish them by touch alone, but by distributing them, it becomes easier to distinguish them, thus preventing accidental operation. This can be used as a criterion for distributing the frequency of use and the functions assigned to each switch. For example, the left switch group 41 consists of switches that are expected to be used relatively frequently when the sensor checker is in operation.

[0052] Furthermore, since the LED lamp switch 45 is expected to be operated while the LED remains lit for a period of time after being operated once, user convenience can be further improved by making it a push switch with a state-locking function that locks after being pushed once and releases after being pushed again. It is also desirable that the pressure or push amount required to determine ON or OFF is at least twice that of the push switches in the lower switch 41 or the right switch group 42.

[0053] Alternatively, instead of providing an LED lamp switch 45, the LED may be controlled to turn off by, for example, pressing and holding switch 42A.

[0054] Figure 2B shows an enlarged view of the area around the right switch group 42. The upper push-type switch 42A is the mode switching switch for the sensor checker. Various measurement modes can be switched each time the switch is pushed. Because it will be operated frequently, it is configured as a push-type switch, but to prevent accidental operation, it is positioned above the slide switch so that it is farther from the grip 12.

[0055] The lower sliding switch 42B is a sensor checker that switches whether the active element used in the circuit being measured is an NPN element or a PNP element.

[0056] By not automatically detecting whether the active element configuration is PNP or NPN, and instead requiring manual switching via a PNP / NPN switch, it becomes easier to determine the cause of the problem if no sensor signal is detected. This could be due to an incorrect setting of the output mode (PNP / NPN) or a sensor malfunction preventing the sensor from outputting a signal. When a sensor signal is output from the sensor, a buzzer sounds and the display on display 11 changes.

[0057] This allows us to provide a sensor checker that improves user convenience.

[0058] Furthermore, in the switch arrangement shown in Figure 1E or Figure 2B, each switch is positioned towards the left side of the diagram. This means that they are positioned towards the front of the sensor checker. This arrangement further improves user convenience during operation.

[0059] Figure 1F is a schematic diagram showing an example of sensor checker usage. According to this embodiment, the user can operate the trigger switch with their fingers while holding the housing, even while connecting to a sensor via the sensor connector or while charging the secondary battery via the USB connector. The cables between sensors and the AC power supply extend from the top and bottom in the longitudinal direction, ensuring ease of operation of the trigger switch and other switches, visibility of the display, and ease of gripping the housing, even while using and / or charging the sensor checker. Furthermore, this embodiment's configuration facilitates charging even while the sensor checker is in use. It is also possible to simultaneously power USB devices using another USB connector provided on the housing.

[0060] The various technical concepts described in this embodiment may be used individually, insofar as they achieve their intended effect. Alternatively, they may be combined with other embodiments.

[0061] Furthermore, the scope of the present application's claims also includes the extent to which the same technical concept can be achieved when applied to various electrical devices other than sensor checkers. [Examples]

[0062] This embodiment describes the internal structural features of an example of a sensor checker.

[0063] Figure 3A is a schematic front view of the sensor checker, corresponding to Figure 1A. Figures 3B and onward show cross-sectional views to illustrate the internal structure.

[0064] Figure 3B shows a schematic cross-sectional structure along line AA in Figure 3A. Note that this figure omits details other than those essential to the explanation. The housing of the sensor checker 10 has a front housing 17A and a rear housing 17B. For example, each is made of resin. The front housing 17A and the rear housing 17B fit together to form the housing 17.

[0065] The sensor checker 10 has a circuit board 15 that partitions at least a portion of the space inside the housing 17. A display 11 is located on one side of the circuit board 15, and a secondary battery 13 is located on the other side of the circuit board 15. This configuration allows for both portability due to the compact housing and increased capacity of the secondary battery, making it suitable for extended use and portability. Furthermore, by adding a mobile battery function to the sensor checker, the battery life is extended even when powering a USB-connected device via the USB connector.

[0066] In this embodiment, the arrangement and configuration of the circuit board 15 are a key feature. The circuit board 15 is positioned within the housing 17, closer to the front housing 17A. The display 11 is positioned above the circuit board 15, on the front housing 17A side. The figure shows an example where the display 11 is positioned on the front housing 17A via a display holder 14. This structure has the effect of protecting the display 11 and simplifying installation. This also includes cases where the display holder 14 is mounted on the circuit board 15, or where the display 11 is mounted on the circuit board 15. It is preferable to position the display 11 close to the front housing 17A to improve visibility. The thickness of the space on one side of the circuit board 15 on the front side of the housing is designed based on the height of the display 11. By sandwiching and supporting the display holder 14 between the housing and the circuit board 15, the rigidity around the display 11 can be increased.

[0067] The sensor checker 10 has a component 16. Component 16 is the second thickest component after the display 11 on the upper side of the circuit board 15. For example, it could be an acoustic component for a buzzer or a speaker, which requires thickness to ensure sufficient volume. This component 16, the second thickest component after the display 11 on the upper side of the circuit board 15, is positioned closer to the sensor connector 30. As a result, other components to be mounted on the circuit board 15 on the upper side of the circuit board 15 are limited to components that are thinner than component 16. Therefore, the grip portion 12 can be configured to the left of the component 16, the second thickest component after the display 11, in the figure, that is, below it in the front view of Figure 3A. The arrangement is not limited to that shown in Figure 3B, and component 16 may be positioned closer to the sensor connector 30 than the display 11.

[0068] The grip portion 12 is integrally formed with the front housing 17A, for example, by slightly recessing or indenting a part of the front housing 17A. Because the thickness of the component placed above the circuit board 15 is limited in this area, the grip portion 12 can be constructed by slightly recessing or indenting without reducing the thickness. This ensures sufficient strength in the grip portion, which is subjected to pressure from the user's grip.

[0069] Furthermore, it is desirable that the circuit board 15 be configured as a single-sided mounting system with components only on the upper side, and that no components be placed on the lower side. This will reduce the thickness of the sensor checker.

[0070] A battery 13 is provided on the underside of the circuit board 15. It may also be called a secondary battery. Figure 3B illustrates an example in which numerous cylindrical batteries 13 (also called cylindrical batteries) are spatially arranged in parallel along the longitudinal direction of the housing.

[0071] Typically, sensors operate at 12-24V. By connecting multiple rechargeable batteries in series, a boost circuit for the sensor checker becomes unnecessary. In this embodiment, 20V or more is achieved by connecting six rechargeable batteries in series. Furthermore, the USB PD (Power Delivery) standard, which uses a USB-C terminal to supply power to other devices (charge other devices) as a mobile battery, specifies power supply corresponding to voltages such as 5V, 9V, 15V, and 20V. By supporting up to 24V for the sensor checker, it is possible to simultaneously support the USB PD standard. Rechargeable batteries include batteries of other shapes, such as rectangular or planar batteries. By connecting multiple batteries of other shapes in series, the number of circuit components can be reduced without the need for boost / buck converters.

[0072] The circuit board 15 requires space for both the sensor checker circuit and the mobile battery circuit. However, in the area where the secondary battery 13 is located, the circuit board 15 is configured as a single-sided mounting system, with components not placed on the lower side. This allows for battery space to be secured without increasing the thickness of the sensor checker, enabling a larger battery and increased capacity. This configuration is particularly desirable when the sensor checker is to have a mobile battery function. On the other side of the circuit board 15, multiple cylindrical batteries are positioned closer to the USB connectors C1 and C2 than the display 11, and are superimposed on the display 11 when viewed from the front of the housing. This configuration achieves both increased capacity and a thinner design using highly reliable, low-cost, general-purpose batteries, without requiring a specially designed battery like those used in smartphones.

[0073] Figure 3B illustrates an example where the grip portion 12 is also provided on the rear housing 17B side. This allows for an even more secure grip for the user.

[0074] The sensor checker 10 has a connection connector 70. The connection connector 70 is a connector for electrically connecting the main body 10A and the sensor connection part 10B.

[0075] In Figure 3B, the circuit board 15 is positioned within the housing 17, towards the front housing 17A side. As a result, the various switches mounted on the circuit board 15 are also unevenly distributed within the housing 17.

[0076] The fact that switch group 41 is positioned to the right in Figures 1D and 2A, and that switch group 42 is positioned to the left in Figures 1E and 2B, is also due to this internal arrangement.

[0077] Figure 3C shows the case where the sensor connection part 10B is removed. Until the sensor connection part 10B is replaced or a new sensor connection part 10B is installed, the connection connector 70 will be exposed.

[0078] Figure 3D shows the case where USB terminals C1 and C2, as shown in Figure 1C, are provided, compared to Figure 3B. In the figure, they are shown as USB connector 80. The USB connector 80 is located below the circuit board 15 and to the left of the battery 13. This allows the USB connector 80 to be located towards the vertical center of the sensor checker in the figure, improving the convenience for the user when using it as a mobile battery. Furthermore, since the size of the USB connector is defined by the standard, it cannot be arbitrarily miniaturized. Therefore, by positioning the circuit board 15 closer to the front housing 17A and placing the USB connector 80 below the circuit board 15, the thickness of the sensor checker can also be reduced.

[0079] Since the USB connectors C1 and C2 are subjected to repeated insertion and removal of cables, it is important to secure the circuit board 15 to prevent the USB connectors from peeling off. In order to secure space for the secondary battery and provide a sufficient holding structure, in this embodiment the USB connectors are positioned on the lower side opposite the upper side where the sensor connector 30 is located.

[0080] Furthermore, as a result of positioning the USB connector 80 on the underside of the circuit board 15, in Figure 1C, C1 and C2 are positioned slightly above the center.

[0081] Figure 3E is a schematic cross-sectional view of the section marked by line BB in Figure 3A. The difference from Figure 3D is that the LED unit 81 is located below the circuit board 15 and to the left of the battery 13.

[0082] The LED unit 81 is a large component in order to ensure sufficient light output. In terms of thickness, it is a thicker component than the display 11. Also, as shown in Figure 1C, it is a large component in order to ensure sufficient light emission area. Therefore, by positioning the LED unit 81 below the circuit board 15 and to the left of the battery 13, it is possible to achieve both the mounting of a large LED unit and a reduction in the thickness of the sensor checker.

[0083] Figure 3F shows an example of the internal structure of the LED unit 81. The LED unit 81 has an LED element 82, a reflector 83, and a diffuser 84. The reflector 83 is made of metal or the like and has the function of concentrating the light from the LED. The diffuser 84 has the function of making the light from the LED uniform. For example, it is made of an opaque, milky white plastic plate. This combination of element, reflector, and diffuser realizes a configuration in which sufficient light intensity and appropriately focused illumination light is emitted from the LED in Figure 1C. This configuration is adopted not as a normal lamp, but based on the performance requirements of a light source intended for the working environment of a sensor checker.

[0084] According to the structure of this embodiment, a sensor checker with improved user convenience can be provided.

[0085] The various technical concepts described in this embodiment may be used individually, insofar as they achieve their intended effect. Alternatively, they may be combined with other embodiments.

[0086] Furthermore, the scope of the present application's claims also includes the extent to which the same technical concept can be achieved when applied to various electrical devices other than sensor checkers. [Examples]

[0087] In this embodiment, further features of the internal structure of an example of a sensor checker will be described.

[0088] Figure 4A is a front view of the circuit board 15 inside the sensor checker. The display 11 is located at the top front of the circuit board 15. A feature of Figure 4A is that multiple holes 90 are provided on the side of the circuit board 15, arranged in parallel in the vertical direction. Since the USB connector 80 is used for inserting and removing cables, the circuit board 15 is fixed to the rear housing 17B with screws or the like at a position close to the USB connector 80. In addition, the rigidity of the circuit board 15 is increased by fixing it to the housing with screws or the like at the middle of the circuit board 15 in the longitudinal direction and at a position close to the sensor connector 30.

[0089] Figure 4B is a schematic transparent view of the substrate 15 to illustrate the effect of the structure shown in Figure 4A. As shown by the dotted lines in the figure, it is shown that multiple batteries 13 from Figure 3B are arranged in parallel in the vertical direction in Figure 4B. The holes 90 in the substrate 15 are provided at positions corresponding to each battery 13. Note that if the battery 13 is flat or rectangular, the image will be as shown in Figure 4C.

[0090] Figure 4D is a schematic cross-sectional view along line CC in Figure 4B. Holes 90 are provided on both sides of the circuit board 15. Legs 91, integrally molded, extend downward from the front housing 17A, passing through the holes 90 in the circuit board 15, and supporting and holding the battery 13 from above. In other words, the holes 90 in the circuit board 15 can also be called holes for fixing the position of the battery, or holes for holding the battery.

[0091] In this way, by providing holes 90 in the substrate 15 and utilizing these holes 90 to fix or hold the battery, the structure for holding the battery can be simplified. As a result, the thickness of the sensor checker and the cost of materials can be reduced. In addition, since the circuit board 15 is supported by the housing independently of the secondary battery, the overall structure of the sensor checker becomes more stable and resistant to impact. Furthermore, the width of the substrate 15 may be narrowed in the short direction at each end in the longitudinal direction. This makes it possible to secure an area for arranging the LED unit 81 and an area for arranging the components for fitting the front housing 17A and the rear housing 17B.

[0092] In Figure 4D, the lower part of the battery 13 is shown to be directly held by the rear housing 17B, but it goes without saying that a separate holding structure may also be provided.

[0093] This structure ensures secure battery retention, thereby improving the reliability of the battery mounting structure in the sensor checker.

[0094] According to the structure of this embodiment, a sensor checker with improved user convenience can be provided.

[0095] The various technical concepts described in this embodiment may be used individually, insofar as they achieve their intended effect. Alternatively, they may be combined with other embodiments. Furthermore, the scope of the present application's claims also includes the extent to which the same technical concept can be achieved when applied to various electrical devices other than sensor checkers. [Examples]

[0096] This embodiment describes the features of a functional block in an example of a sensor checker.

[0097] Figure 5 is an example of a functional block diagram.

[0098] CPU100 is the first CPU. CPU200 is the second CPU. One of the features of Figure 5 is that it has multiple CPUs, and only one of them can be selectively put into a hibernation state.

[0099] CPU100 is the CPU responsible for controlling the sensor functions as a sensor checker. CPU200 is the CPU primarily responsible for controlling parts other than the sensor functions. An example of CPU100 and CPU200 is described below.

[0100] The CPU 100 implements a connected device detection means 101, an output specification detection means 102, a sensor output detection means 103, a buzzer setting detection means 104, and a trigger transmission means 105. Each of these means can also be referred to as a function.

[0101] The CPU 100 receives signals directly or indirectly from the sensor input / output terminal 110. The power switch 111 turns the CPU 100 ON or OFF. This corresponds to the slide switch 41A in Figure 2A. This switch allows selective power OFF to only the CPU 100. Note that even if the power switch 111 is turned OFF, the CPU 200 does not turn OFF. Therefore, even if the power switch 111 is turned OFF, the mobile battery function remains available. In other words, when switch 41A (power switch) is OFF, trigger transmission to the sensor is prohibited regardless of the operation of the trigger switch 41B. When switch 41A is OFF, even if the sensor is connected to the sensor connector 30, power supply from the secondary battery 13 to the sensor is prohibited, while power supply from the secondary battery 13 to USB devices connected to USB connectors C1 and C2 is performed. As a result, the sensor checker function can be turned OFF when not needed to avoid power consumption and avoid affecting the convenience of the mobile battery function. This feature makes it possible to integrate a mobile battery function into a sensor checker, enabling both functionality and performance simultaneously.

[0102] The mobile battery's usage status (charging / power supply) is recognized via communication functions through physical insertion and removal. For example, in the case of USB, the status of the connected device (fully charged and no power supply from the mobile battery is needed, operation stopped) can be determined through communication, so an ON / OFF switch on the mobile battery is unnecessary. In other words, switch 41A (power switch) is only necessary because it is a sensor checker. To prevent unintended battery drain caused by leaving the sensor connected, operating switch 41A (power switch) turns off the display 11 and stops the power supply to the sensor via the sensor connector 30.

[0103] The CPU 100 is connected to the signal from the mode button 112. The mode button 112 corresponds to the upper push-button switch 42A in Figure 2B. It is connected to the NPN / PNP output switching button 113, which corresponds to the lower slide-type switch 42B in Figure 2B. It is connected to the trigger switch 114, which corresponds to the central switch 41B in Figure 2A. It is connected to the buzzer ON / OFF switch 115, which corresponds to the lower switch 41C in Figure 2A. It is connected to the buzzer 116, which, for example, corresponds to component 16 in Figure 3B, and corresponds to the buzzer, which is the second thickest component after the display 11 on the upper side of the circuit board 15.

[0104] CPU200 is primarily responsible for controlling functions other than the sensor equipment. Therefore, control related to the mobile battery function is mainly handled by CPU200. Furthermore, CPU200 continues to operate even when CPU100 is powered off.

[0105] The CPU 200 includes a display control means 201. The display control means 201 controls the display on the display 205. This display 205 corresponds to the display 11 in Figure 1A.

[0106] It has a light emission control means 202 that controls the LED lighting 430. The LED lighting 430 corresponds to the LED shown in Figure 1C. By operating the lighting switch 206, the light emission control means 202 controls the on / off state, brightness levels, etc., of the LED lighting 430. The lighting switch 206 corresponds to, for example, the LED lamp switch 45 shown in Figure 1E.

[0107] Furthermore, it includes a battery level detection means 203 and a power consumption control means 204.

[0108] Each of these means can also be called a function.

[0109] By implementing the display control means 201, light emission control means 202, battery level detection means 203, and power consumption control means 204 in the CPU 200, the mobile battery function can be realized even when the CPU 100 is turned off.

[0110] The CPU 200 controls the battery (secondary battery) 400. The battery (secondary battery) 400 corresponds to, for example, battery 13 in Figure 3B. USB port 1, 411, and USB ports 2, 411 and 422, correspond to C1 and C2 in Figure 1C, respectively. The charge / discharge control circuit 1, 410, and the charge / discharge control circuit 2, 420, are controlled by the CPU 200 to control the power supply from the battery (secondary battery) 400 to each USB port, or the charging of the battery (secondary battery) 400 from each USB port.

[0111] When CPU100 is powered on, i.e., when its function as a sensor checker is ON, CPU100 and CPU200 cooperate with each other to adjust the content displayed on the screen, etc.

[0112] The memory unit 300 stores a sensor checker screen display program 301 and a mobile battery screen display program 302. Each program may be preloaded into each CPU before execution. Alternatively, each CPU may have the necessary programs for its functions pre-installed in its own memory area.

[0113] It should be noted that the means and functions described above are merely examples, and of course, other means and functions may also be included.

[0114] According to the functional block structure described in this embodiment, the associated CPU is operated only when the sensor or sensor checker function is ON. This achieves both reduced power consumption when not needed and the continuous maintenance of the mobile battery function.

[0115] Therefore, according to the functional block structure described in this embodiment, it is possible to provide a sensor checker with a mobile battery function that improves user convenience.

[0116] Furthermore, by placing the CPU 100 on the sensor connector 30 side and the CPU 200 on the USB connectors C1 and C2 side, it becomes easier to achieve a balanced circuit layout, allowing the CPUs 100 and 200 to be mounted on essentially one side of the circuit board 15.

[0117] The various technical concepts described in this embodiment may be used individually, insofar as they achieve their intended effect. Alternatively, they may be combined with other embodiments.

[0118] Furthermore, the scope of the present application's claims also includes the extent to which the same technical concept can be achieved when applied to various electrical devices other than sensor checkers. [Examples]

[0119] This embodiment describes the operational flow characteristics of an example of a sensor checker.

[0120] Figure 6A is an example of an operation flowchart. Step S1 is the start. In step S2, it is determined whether the sensor checker screen mode is the sensor checker MODE screen or not. Depending on the result of the determination, in step S3 the display 11 displays the mobile battery MODE screen, or in step 4 the display 11 displays the sensor checker MODE screen. For example, the screen mode can be switched by long-pressing the mode switch 42A in Figure 2B. Note that the operation flowchart in Figure 6A is assumed to be running continuously. Therefore, even if it reaches step S3 or step S4, it always restarts from step S1 and is an operation flowchart that runs continuously.

[0121] Figure 6B shows the operation flow when the mobile battery MODE screen is selected. In Figure 6A, this can also be described as the case where the mobile battery MODE screen is displayed at S3.

[0122] Step S11 initiates the process. In step S12, the connected device detection means detects the connected device and determines whether it is charging or powering. If either charging or powering is achieved, the process proceeds to step S13. If neither applies, the process returns to before step S12 and continues in a standby state.

[0123] In step S13, the display control means displays the mobile battery MODE screen on the display 11. This allows the user to check the battery status on the display when charging or supplying power.

[0124] In step S14, the battery level detection means detects the remaining battery level.

[0125] In step S15, the power consumption detection means detects the power consumption due to power supply or charging.

[0126] In step S16, the display control means displays the battery level and power consumption on the display. At the same time, the display shows the status (ON or OFF) of the slide switch 41A.

[0127] Step S13 is optional, and the information may be displayed on the display 11 all at once at the timing of step S16. Steps S14 and S15 can be performed in any order.

[0128] The display of the slide switch 41A indicates its status (ON or OFF), which allows users to easily understand the mode and use the sensor checker smoothly when it is equipped with a mobile battery function. Without this display function, users would have to visually check the status of the physical button to confirm the mode or status of the sensor checker. This is especially difficult when the user is holding the device in their hand. Therefore, the function of displaying whether the sensor or sensor checker function is OFF is important for improving user convenience.

[0129] Figure 6C shows the operation flow when the sensor or sensor checker is ON. In Figure 6A, this can also be described as the case where the sensor checker MODE screen appears in step S4.

[0130] Start at step S21.

[0131] In step S22, the output specification detection means detects whether NPN or PNP is selected using the output selector switch. The buzzer setting detection means also detects whether the buzzer is ON or OFF. The display control means displays the sensor checker screen corresponding to the detected setting.

[0132] In step S23, the sensor output detection means detects whether the sensor's output terminal is 0V (ON) or not (OFF) according to the specified output specification (NPN / PNP), and whether the sensor's output terminal is 24V (ON) or not (OFF) if it is PNP.

[0133] In step S24, determine if the sensor output is ON. If YES, i.e., ON, proceed to step S25. If NO, i.e., OFF, loop back to before step S24.

[0134] In step S25, the display control means displays on the screen that the sensor is ON.

[0135] In step S26, it is determined whether the buzzer setting is ON. If YES, i.e., ON, the process moves to step S27 and the buzzer sounds. Then, it loops back to before step S24. If NO, i.e., OFF, it loops back to before step S24, meaning the buzzer does not sound. Note that steps S25 and S26 can be performed in any order.

[0136] According to the operation flow described in this embodiment, it is possible to easily switch between the sensor checker MODE screen and the mobile battery MODE screen. Therefore, when a mobile battery function is incorporated into a sensor or sensor checker, it becomes easier for the user to access the information they want to check, thus providing a sensor checker with a mobile battery function that improves user convenience.

[0137] The various technical concepts described in this embodiment may be used individually, insofar as they achieve their intended effect. Alternatively, they may be combined with other embodiments.

[0138] Furthermore, the scope of the present application's claims also includes the extent to which the same technical concept can be achieved when applied to various electrical devices other than sensor checkers. [Examples]

[0139] This embodiment describes the screen display features of an example of a sensor checker.

[0140] Figure 7A shows an example of the display on the sensor checker's display 11. This is an example of using both the mobile battery function and the sensor checker function simultaneously.

[0141] The battery level is displayed numerically in the upper left. The battery level is displayed graphically in the lower left. In the upper right, the voltage and current output to the sensor via the sensor connector 30 when used as a sensor checker are displayed. Sensor failures can be identified by overcurrent or lack of expected current consumption. In the lower right of the diagram, the power supply voltage and power supply current to external devices from USB connectors C1 and C2 in Figure 1C, when used as a mobile battery, are displayed.

[0142] Figure 7B shows an example of the screen display on display 11 when the mobile battery MODE screen is selected. Figure 7B also shows an example of the screen display when a sensor is connected but the mobile battery is not supplying power to an external source.

[0143] The battery level is displayed numerically in the upper left corner. The battery level is displayed graphically in the lower left corner. When used as a sensor checker, the battery level is displayed, as in Figure 7A, to allow users to understand the remaining usable time and status of the sensor checker.

[0144] On the upper right side, the output from sensor connector 30 when used as a sensor checker is displayed.

[0145] Figure 7C shows an example of the screen display on display 11 when the mobile battery MODE screen is selected. The left side of the screen is the same as in Figure 7A. The difference is that the upper right of the figure does not show any display related to the output from the sensor connector 30.

[0146] Figure 7D shows an example of the screen display when the Sensor Checker MODE screen is selected and the NPN / PNP discrimination function is being performed as a sensor checker using the mode switch 42A in Figure 2B.

[0147] The upper left of the diagram shows either NPN or PNP, indicating which is selected in the right switch group 42 in Figure 2B. The upper center of the diagram shows the sensor input. When switch 41B is pressed to provide input to the sensor, it is indicated by changing its color. At that time, text is also displayed, and the area around it is colored to improve user visibility.

[0148] The upper right of the diagram shows the speaker or buzzer status graphically or using icons. When the lower switch 41C in Figure 2A is ON, the display in the upper right of the diagram makes it easy to see that the speaker or buzzer is ON.

[0149] The lower part of the diagram is a display that receives output from the sensor and acts as an indicator light for the sensor. In this embodiment, the size is enlarged so that the sensor's response is easily visible.

[0150] Figure 7E shows an example of the screen display when the Sensor Checker MODE screen is selected and the NPN / PNP discrimination function is being performed as a sensor checker using the mode switch 42A in Figure 2B. This is an example where PNP is selected in the right switch group 42 in Figure 2B, and "PNP" is displayed in the upper left. The speaker or buzzer display in the upper right corresponds to the OFF state, and is indicated with an X mark or similar to make the OFF state easily recognizable. The sensor output area at the bottom is not displayed, as is clear from the comparison with the display in Figure 7D. By comparing the two, the user can clearly understand that no sensor output is being performed. The screen display examples in Figures 7A to 7E are merely examples.

[0151] The display 11 simultaneously or by switching between displays related to the mobile battery function and displays related to the sensor checker function. Furthermore, when the display 11 simultaneously displays displays related to the mobile battery function and displays related to the sensor checker function, it displays charging information in the first color, power supply information in the second color, and information related to the sensor connected to the sensor connector 30 in the third color, thereby achieving a display that is easy for the user to distinguish. The display 11 is a multi-functional display that goes beyond conventional monochrome displays, lamp displays, and displays of numbers and letters only, and is capable of displaying multiple colors and simultaneous display of text and graphic information, thus enabling accurate information provision to the user. In addition, since various types of displayable information can be set, even in a sensor checker that enables various measurements by replacing the sensor connection part 10B in Figure 1A, it is possible to provide appropriate information to the user.

[0152] The screen display features described in this embodiment enable accurate information provision to the user. Therefore, when a mobile battery function is incorporated into a sensor or sensor checker, the user can understand and operate the information without confusion. This allows for the provision of a sensor checker with a mobile battery function that enhances user convenience. [Examples]

[0153] Figures 8A to 8E correspond to Figures 1A to 1E of Example 1.

[0154] The main difference in appearance between this embodiment and Embodiment 1 lies in the structure of the corners.

[0155] In the figures for Example 1, the corners were shown with arc-shaped or curved structures. In this example, the corners are connected by straight lines or cut off.

[0156] This reduces the volume of dead space in the corners, allowing for miniaturization of the sensor or sensor checker. Simultaneously, it also reduces the volume of the exterior components, resulting in a lighter sensor or sensor checker. [Examples]

[0157] Figure 9 illustrates the additional structure provided in this embodiment compared to Figure 1A or Figure 8A.

[0158] A key feature of Figure 9 is the presence of an anti-slip surface 60. As its name "handheld" suggests, the sensor checker is designed to be operated while held in the hand. Therefore, it is desirable to take precautions to prevent it from slipping from the operator's hand during operation. Thus, in Figure 9, an anti-slip surface 60 is provided. Various configurations can be applied to the anti-slip surface 60, but in Figure 9, it is realized with a configuration of numerous linear grooves or indentations arranged in parallel. This allows the operator to get a better grip on the sensor checker's hand than if it were completely flat, thus providing an anti-slip function. There are no particular limitations on its size, number, or detailed shape. However, a configuration with multiple parallel surfaces is desirable from the viewpoint of ease of arrangement and ease of manufacturing. The various technical concepts described in each embodiment may be used individually, as long as they achieve their effects. Alternatively, they may be combined with other embodiments. Furthermore, the scope of the present application's claims also includes the extent to which the same technical concept can be achieved when applied to various electrical devices other than sensor checkers.
