Japanese Patent No. 5751400

  In a conventional measurement device, the measurement start button may be used also as a button for performing other operations. In this case, measurement start can be instructed by the measurement start button only under specific conditions. . Therefore, in order to instruct the start of measurement, a complicated operation for shifting to a specific condition is required each time. For example, in the case where measurement is repeatedly performed while finely adjusting the measurement position, complicated operations can be repeated. In addition, for example, when the state of the measurement object changes from moment to moment, the measurement timing (opportunity) may be missed by being forced to perform complicated operations.

  An object of the present invention is to provide a measuring device that is advantageous in terms of operability, for example.

<1. Equipment overview>
A measuring apparatus according to the present embodiment will be described with reference to FIGS. FIG. 1 is an external view of a measuring device 10 according to the present embodiment, FIG. 2 is a diagram showing an internal configuration of the measuring device 10 viewed from the X direction, and FIG. 3 is a block diagram showing a functional configuration of the measuring device 10. is there. The measurement apparatus 10 that measures the characteristics of an object can include, for example, a housing 11, a detection unit 12, a display unit 14, an operation unit 15, and a control unit 16. For example, the measurement apparatus 10 measures the reflection characteristics of the measurement target surface 20 that is an object through the opening 17 formed in the housing 11 in a state where the external light is blocked by the housing 11. The housing 11 has a substantially rectangular parallelepiped configuration, for example. Here, the reflection characteristic may include at least one of specular gloss, haze, DOI, image clarity, and BRDF, for example. DOI is an abbreviation for Distinctness of Image. BRDF is an abbreviation for Bidirectional Reflectance Distribution Function, and is an index representing a bidirectional reflectance distribution.

  The control unit 16 includes, for example, an MCU (Micro Controller Unit) and controls each unit of the measurement apparatus 10. The control unit 16 has a function as a processing unit that obtains the reflection characteristics of the measurement target surface 20 based on the detection result of the detection unit 12. However, the processing unit may be provided separately from the control unit 16. The control unit 16 may include a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), or the like instead of the MCU or in addition to the MCU.

  The housing 11 has, for example, a first surface 11a (bottom surface) in which an opening 17 is formed, a second surface 11b (upper surface) opposite to the first surface 11a, and a side surface 11c. When measuring, the first surface 11a is placed on the measured surface 20 such that the first surface 11a is on the measured surface side (so that the first surface 11a faces the measured surface 20). A detection unit 12 and a control unit 16 are provided in the housing 11, and a display unit 14 and an operation unit 15 (operation button group) are provided on the second surface 11 b of the housing 11. The operation unit 15 as an input unit includes a measurement button 15a for instructing measurement start. When the user presses the measurement button 15a, a measurement start instruction is input to the control unit 16. Alternatively, the input unit may include a reception unit that receives a measurement start instruction from an external device, and the measurement start instruction may be input to the control unit 16 via the reception unit.

  The control unit 16 (processing unit) and the detection unit 12 may constitute the measurement unit 5 that measures the reflection characteristics of the object in accordance with the input measurement start instruction. The control unit 16 causes the display unit 14 to display a result screen indicating the measurement result. The detection unit 12 is configured to irradiate the region of the measurement target surface 20 through the opening 17 and detect the light reflected by the measurement target surface 20. The detection unit 12 includes a light source 12a and a lens 12b, and irradiates the measurement target surface 20 with light. The light source 12a is connected to the light source control circuit 12c, and the light emission intensity is adjusted according to a signal sent from the control unit 16 to the light source control circuit 12c. The light emitted from the light source 12 a is converted into parallel light by the lens 12 b, passes through the opening 17, and enters the measurement target surface 20. The detection unit 12 includes a sensor 12d and a lens 12e, and receives (detects) light reflected by the measurement target surface 20. The sensor 12d includes, for example, an area sensor in which photoelectric conversion elements composed of a CCD, a CMOS, or the like are two-dimensionally arranged. The sensor 12d receives light reflected by the measurement target surface 20 and collected by the lens 12e. The intensity distribution of the reflected light from the measurement surface 20 is detected. The control unit 16 can perform calculation based on the intensity distribution data of the reflected light output from the sensor 12d (detection result of the detection unit 12), and obtain the reflection characteristic of the measurement target surface 20.

  A value indicating the reflection characteristic of the measurement target surface 20 obtained by the control unit 16 is displayed by the display unit 14. The display unit 14 is configured by, for example, an LCD provided on the second surface 11b of the housing 11. The display unit 14 displays a value indicating the reflection characteristic of the measurement target surface 20. Thereby, the user can visually recognize the reflection characteristics of the measurement target surface 20.

  Setting of measurement conditions and the like of the measurement device 10 is also performed by operating the operation unit 15 while the user visually recognizes it. The operation unit 15 can be configured by a plurality of operation buttons including a measurement button 15 a provided on the second surface 11 b of the housing 11. The plurality of operation buttons including the measurement button 15a may be configured by a mechanical switch, or may be configured by a capacitance sensor, a temperature sensor, an optical sensor, or the like that senses a user's hand (finger) contact. . The measuring device 10 may include a touch panel arranged so as to be superimposed on the display unit 14 configured by an LCD, and these operation buttons may be configured by the touch panel. For example, the measurement button 15a is configured to output a measurement start signal when the user touches the measurement button 15a (when the user presses the measurement button). Alternatively, the measurement button 15a may be configured to output a measurement start signal when the user releases the measurement button 15a (when the measurement button that has been pressed is released).

  In response to detecting a signal generated when the measurement button 15 a is pressed by the user, the control unit 16 starts measuring the reflection characteristics of the measurement target surface 20. Here, the incident angle θ of light incident on the measurement target surface 20 when measuring the reflection characteristics of the measurement target surface 20 (the reflection angle θ ′ of light reflected from the measurement target surface 20) is JIS, ISO, or the like. It is defined for each reflection characteristic according to the standard. For example, when the specular glossiness is measured as the reflection characteristic, the incident angle θ (reflection angle θ ′) is defined as one of 20 degrees, 45 degrees, 60 degrees, 75 degrees, and 85 degrees. In the case of measuring haze as the reflection characteristic, the incident angle θ (reflection angle θ ′) is defined as either 20 degrees or 30 degrees. When DOI (image clarity) is measured as the reflection characteristic, the incident angle θ (reflection angle θ ′) is defined as any one of 20 degrees, 30 degrees, 45 degrees, and 60 degrees. In the example shown in FIG. 2, one detection unit 12 is provided, and the reflection characteristics of the measurement target surface 20 are measured at one type of incident angle θ (reflection angle θ ′). However, as described above, the incident angle θ (reflection angle θ ′) is defined for each reflection characteristic standard. Therefore, a plurality of detection units 12 having different incident angles θ (reflection angles θ ′) are measured so that the reflection characteristics of the measurement target surface 20 can be measured at a plurality of types of incident angles θ (reflection angles θ ′). You may provide in the apparatus 10. FIG. For example, when the detection unit 12 having an incident angle θ (reflection angle θ ′) of 20 degrees and the detection unit 12 having an incident angle θ (reflection angle θ ′) of 60 degrees are provided in the measuring apparatus 10, the specular glossiness is increased. , Haze, and DOI can be measured. In addition, the measurement unit 10 is not limited to providing the plurality of detection units 12, and a drive unit that drives the detection unit 12 is configured to be able to change the incident angle θ (reflection angle θ ′) in one detection unit 12. It may be provided.

  As shown in FIG. 3, the control unit 16 (processing unit) includes a display control unit 161, a ROM 162 and a RAM 163 as storage units, a communication control unit 164, a measurement control unit 165, a calculation unit 166, and an imaging control unit 167. sell. The ROM 162 is a read-only memory, and stores in advance various data such as a startup program for the measurement device, a measurement processing program, and a plurality of screen data. The RAM 163 is a readable / writable memory that provides a work area for the control unit 16 and stores setting data such as measurement conditions, measurement result data, and the like. In addition to the RAM 163, an external memory may be connected. Further, the display unit 14, the operation unit 15, the detection unit 12, and the imaging unit 18 are connected to the control unit 16. The control unit 16 stores the calculation result of the reflection characteristics (one or more of specular gloss, haze, DOI, and BRDF) in the RAM 163 and causes the display unit 14 to display the result. The control unit 16 may transmit the calculation result to an external device through the communication control unit 164 or may store the calculation result in the RAM 163.

  The imaging unit 18 (not shown in FIG. 2) images the area of the measurement target surface 20. An image of the measurement target surface 20 obtained by the imaging unit 18 is displayed on the display unit 14. Thereby, since the user can visually recognize the measurement area and its periphery on the display unit 14, the measurement apparatus 10 can be easily and accurately positioned so that the measurement area is arranged in the target area.

  The measurement device 10 may further include a power switch (not shown), a built-in battery, a power supply and communication cable connector, and the like. For example, when the measuring device 10 and an external device such as a computer are connected, the data of the reflection characteristic calculation result may be transferred to the external device, and the value of the reflection characteristic may be displayed on the external device display unit.

<2. Example of screen transition>
The display control unit 161 controls screen display on the display unit 14. For example, the display control unit 161 changes the display screen displayed on the display unit 14 in response to a signal input according to the operation of the operation unit 15 by the user. Specifically, the screen related to one of the plurality of screen data is changed to the screen related to one other screen data different from the one screen data. The plurality of screen data are hierarchized, and the screen transition is performed according to an operation of tracing between the hierarchies by the user.

  For example, as shown in FIG. 4, the screen transition rule includes a rule in which a plurality of screens are associated in a tree shape and the display control unit 161 makes a transition. The measurement screen D0 (main screen) is defined as one screen that is the starting point of the highest first hierarchy H1. In addition, the menu screen Dm belongs to the second hierarchy H2 as one hierarchy below the first hierarchy H1. A third hierarchy H3 as a hierarchy below one of the second hierarchies H2 includes a menu a screen Da, a menu b screen Db, and a menu c screen Dc. The fourth hierarchy H4 as one hierarchy below the third hierarchy H3 includes a menu a1 screen Da1, a menu a2 screen Da2, and a menu a3 screen Da3. One screen related to the screen data of the first layer among the first to fourth layers H1 to H4 is displayed on the display unit 14. Then, the display screen of the display unit 14 is changed from the single screen by the display control unit 161 in response to a signal input in response to the user's operation in a state where one screen of one layer is displayed on the display unit 14. A transition is made to another screen related to screen data of another layer one level lower or higher than the first layer. For example, such a screen transition rule is easy to use to set the measurement conditions of the apparatus.

  Other screen transition rules include, for example, a rule in which a plurality of screens are sequentially transitioned and transitioned by the display control unit 161 as shown in FIG. This is a screen transition in which screens in one hierarchy are displayed in order. For example, such a screen transition rule is easy to use for displaying a plurality of histories such as past reflection characteristic calculation results.

  In recent years, devices have become more multifunctional so that various settings and displays can be performed, and a wide variety of display screens exist, so a combination of these screen transition rules or other screen transition rules can be combined. Screen transitions may occur.

<3. Flow example 1>
Next, a flow for measuring the reflection characteristic of the measurement target surface 20 using the measurement apparatus 10 will be described with reference to FIGS. 6 and 9. FIG. 6 is a flowchart of a measurement process for measuring the reflection characteristic of the measurement target surface 20. A program corresponding to the flowchart of FIG. 6 is included in, for example, a measurement processing program stored in the ROM 162, and can be executed by the control unit 16 (processing unit). FIG. 9 shows a specific example of the transition screen.

  S101 is a step of changing the screen displayed on the display unit 14 from the measurement screen D0 (main screen) in FIG. 4 to the menu a1 screen Da1 (screen A) according to the operation of the operation unit 15. Here, a specific example of the measurement screen D0 (main screen) in FIG. 4 is shown in FIG. 9A, a specific example of the menu screen Dm is shown in FIG. 9B, and a specific example of the menu a screen Da is shown. FIG. 9C shows a specific example of the menu a1 screen Da1. First, the main screen of FIG. 9A is changed to FIG. 9B, which is a menu screen, with the right operation button. The list in the menu screen of FIG. 9B has three options “Camera”, “Settings”, and “Statistics”, which are selected with the up / down operation buttons. Here, “Camera” (transition to the imaging mode of the surface to be measured) is selected and determined with the right operation button. Then, the screen transitions to FIG. 9C, which is a screen for selection of positions to be imaged by the imaging unit 18. In the list in the screen of FIG. 9C, there are three options “20 deg”, “60 deg”, and “85 deg” related to the incident angle θ, which are selected with the up and down operation buttons. Here, “20 deg” is selected and determined with the right operation button. Then, the screen transitions to FIG. 9D, which is a display screen of the image of the measurement target surface 20 imaged by the imaging unit 18. Here, this display screen is the screen A of S101.

  In S102, the user can adjust the position where the reflection characteristic is measured while viewing the image of the measurement target surface 20 displayed on the display unit 14, and thereby the measuring device 10 is positioned. When the measurement apparatus 10 starts measuring the reflection characteristics, the user presses the measurement button 15a. In S103, the control unit 16 determines whether or not to start measurement based on whether or not a measurement start signal (measurement start instruction) from the measurement button 15a is detected. That is, the detection of the measurement start signal serves as a trigger for starting measurement. Alternatively, measurement of reflection characteristics may be started in response to detection of a measurement start signal received from an external device (for example, a computer device) connected to the measurement device 10. Alternatively, the measurement start instruction may be input as a user's voice command using voice recognition technology.

  If no measurement start signal is detected in S103, the process returns to S101. If a measurement start signal is detected, the process proceeds to S104. At this time, the “Measure” option is displayed and can be selected from the operation unit 15. If “Do not measure (cancel)” is selected, the process may return to S 101.

  In S104, the screen A (pre-measurement screen) displayed on the display unit 14 when the measurement start instruction is input or information indicating the screen A is stored in the RAM 163. In this example, the screen A is a display screen of an image (video) of the measurement target surface 20 as shown in FIG.

  In S105, measurement is started. Specifically, the control unit 16 irradiates the measurement target surface 20 with light from the detection unit 12. The light reflected by the measurement target surface 20 is detected by the detection unit 12 (sensor 12d). In S106, the control unit 16 obtains the reflection characteristic of the measurement target surface 20 based on the detection result (the intensity distribution data of the reflected light output from the sensor 12d) in the detection unit 12. At this time, the control unit 16 stores the obtained reflection characteristic in the RAM 163. At least during the execution of measurement, an image indicating that the measurement is being executed may be displayed. For example, during the period from S104 to S106 (from the time when the measurement start signal is detected until the reflection characteristic is obtained), during the measurement as shown in FIG. A message ("Measuring ...") is displayed in a superimposed manner.

  In S107, the display control unit 161 changes the screen from the menu a1 screen Da1 in FIG. 4 to the measurement screen D0. Here, from FIG. 9D, which is a screen image of the measurement target surface 20, the measurement screen D0 is automatically transitioned to a result screen showing the measurement result. In this way, the control unit 16 displays the calculation result of the reflection characteristic obtained in S106 on the display unit 14. Accordingly, here, after passing through FIG. 9D to FIG. 10A, a result screen as shown in FIG. 9E is displayed.

  S108 is a step in which the control unit 16 determines whether or not to perform screen transition after displaying the result screen. Specifically, the control unit 16 determines whether to perform screen transition based on the screen A or information indicating the screen A stored in the RAM 163 in S104. For example, when the screen A displayed in S101 is a display screen for the image of the measurement target surface 20, the process returns to S101 and the screen A is displayed again. That is, the screen displayed on the display unit 14 returns from FIG. 9 (e) to the screen A in FIG. 9 (d). As a result, the user can continue to measure the reflection characteristics while viewing the image of the measurement target surface 20. This saves the user from having to go back and forth between screen transitions every time measurement is performed, which is advantageous for repeated measurement while finely adjusting the location. Furthermore, when the state of the surface 20 to be measured changes from moment to moment, it is advantageous for measurement without missing the timing to be measured.

  If the screen A displayed in S101 is not a display screen for the image of the surface 20 to be measured, the screen does not return to the screen A in FIG. 9D, and the result screen in FIG. Return to. For example, the case where the screen A is a menu screen as shown in FIG. 9B and the measurement is started in a state where the menu screen is displayed may be considered. In this case, the screen A is not returned from S108 (the measurement screen of FIG. 9E is not returned to the menu screen of FIG. 9B), and the measurement screen of FIG. Thus, the user can continue to measure the reflection characteristic in the state of the measurement screen, and the time and effort for returning to the measurement screen when performing the measurement again can be saved.

  In this embodiment, if it is determined in S108 that the screen A is a display screen of the image of the surface 20 to be measured, the process proceeds to S101; otherwise, the process proceeds to S103. It does not have to be. For example, if the screen A is any one of the image display screen of the measurement target surface 20, the measurement condition setting screen, and the measurement history screen, the process may proceed to S101. Even if it is a screen of, you may make it progress to S101. That is, there may be one or more candidate screens that return from S108 to S101. This distribution rule may be determined in advance and stored in the ROM 162, or may be stored in the RAM 163 so that the user can select and set the distribution screen rule.

<4. Flow example 2>
Next, another flow for measuring the reflection measurement of the measurement target surface 20 using the measurement apparatus 10 will be described with reference to FIG. FIG. 7 is a flowchart of measurement processing for measuring the reflection characteristic of the measurement target surface 20 as in FIG. 6. The same processing steps as those in FIG. 6 are denoted by the same reference numerals, and description thereof will be omitted. In FIG. 7, S109 is executed instead of S108 of FIG.

  In S107 to S109, the control unit 16 displays the calculation result (FIG. 9E) for a predetermined time (for example, 1 to 3 seconds) that is an appropriate time for the user to check the calculation result. After a predetermined time has elapsed after displaying the result screen, the process returns to S101, and the control unit 16 displays a display screen (FIG. 9D) of the image of the measurement target surface 20 obtained by the imaging unit 18. Display on the unit 14. Thereby, the user can continue to measure the reflection characteristic of the measurement target surface 20 after confirming the calculation result. The predetermined time may be set by the user in a time between 0 seconds and 5 seconds, for example, in consideration of not confirming the result or confirming a longer time. Setting information for these predetermined times can be stored in the RAM 163.

  In addition to S101, the transition after the predetermined time elapses may be made to transition to S103 in addition to S101 according to screen A as in flow example 1 (FIG. 6) (S103 in FIG. 7). Dashed arrow heading to).

  In the flow examples of FIGS. 6 and 7 described above, the screen transitioned from S108 or S109 (screen A) is the screen of the image of the surface to be measured 20, but is not limited thereto. For example, when the screen A is a screen that displays a history such as past calculation results, it is advantageous for comparing changes such as a difference between the latest calculation results and past calculation results. In particular, when the calculation result is BRDF, it is advantageous to quickly grasp the location dependency of BRDF. Further, when the screen A is a statistical display screen such as statistics or histograms of calculation results obtained by measuring a plurality of times, it is advantageous for quickly grasping where the latest calculation results are located in the statistical distribution.

<5. Flow example 3>
In the flow examples of FIGS. 6 and 7 described above, the screen transitioned from S108 or S109 is the pre-measurement screen or the result screen, but is not limited thereto. That is, the flow may be a transition to a third screen other than the pre-measurement screen and the result screen. Measurement processing according to this flow will be described with reference to FIGS. 8 and 11. FIG. 8 is a flowchart of a measurement process for measuring the reflection characteristic of the measurement target surface 20. FIG. 11 shows a specific example of the transition screen.

  S110 is a step of changing the screen displayed on the display unit 14 from the measurement screen D0 of FIG. 4 to the menu a screen Da (screen preA) in accordance with the operation of the operation unit 15. Here, a specific example of the measurement screen D0 is shown in FIG. 11 (a), a specific example of the menu screen Dm is shown in FIG. 11 (b), and a specific example of the menu a screen Da is shown in FIG. 11 (c). Has been. First, when the user operates the right operation button on the operation unit 15 from the main screen of FIG. 11A, the screen transitions to FIG. 11B, which is a menu screen. In FIG. 11B, there are three options “Camera”, “Settings”, and “Statistics” in the list on the screen, and the user can select with the up / down operation buttons on the operation unit 15. Here, it is assumed that the user selects “Settings” (transition to the setting mode for determining the measurement condition) with the up and down operation buttons and decides with the right operation button. Then, the screen transitions to FIG. 11C which is a screen for measurement condition options. Here, the screen of FIG. 11C is the screen preA.

  S111 is a step of changing the screen displayed on the display unit 14 from the menu a screen Da (screen preA) in FIG. 4 to the menu a1 screen Da1 (screen A) in accordance with the operation of the operation unit 15. Here, a specific example of the menu a screen Da is shown in FIG. 11C, and a specific example of the menu a1 screen Da1 is shown in FIG.

  The list in the screen of FIG. 11C has three options “20 deg”, “60 deg”, and “85 deg” related to the incident angle θ, and the user can select with the up / down operation buttons. Here, it is assumed that the user selects “20 deg” with the up and down operation buttons and decides with the right operation button. Then, a display screen as shown in FIG. 11D is displayed on the display unit 14. Here, the screen of FIG.

  In S102, the user can adjust the position where the reflection characteristic is measured while viewing the image (FIG. 11 (d)) displayed on the display unit 14 and set so as to be able to measure at 20 deg. Thus, the measuring device 10 is positioned. When the measurement apparatus 10 starts measuring the reflection characteristics, the user presses the measurement button 15a. In S103, the control unit 16 determines whether to start measurement based on whether a measurement start signal from the measurement button 15a is detected. That is, the detection of the measurement start signal serves as a trigger for starting measurement. If no measurement start signal is detected in S103, the process returns to S111. If a measurement start signal is detected, the process proceeds to S114.

  In S114, the screen preA displayed in S110 or information indicating the screen preA is stored in the RAM 163. At this time, screen A or information indicating screen A may also be stored in RAM 163. Here, the screen preA refers to FIG. 11 (c) which is a screen of options of positions to be measured, and the screen A is a screen in a state set so as to be able to measure at 20 degrees. It is (d).

  In S105, measurement is started. Specifically, the control unit 16 irradiates the measurement target surface 20 with light from the detection unit 12. The light reflected by the measurement target surface 20 is detected by the detection unit 12 (sensor 12d). In S106, the control unit 16 obtains the reflection characteristic of the measurement target surface 20 based on the detection result (the intensity distribution data of the reflected light output from the sensor 12d) in the detection unit 12. At this time, the control unit 16 stores the obtained reflection characteristic in the RAM 163.

  In S107, the display control unit 161 changes the screen from the menu a1 screen Da1 in FIG. 4 to the measurement screen D0. Here, the screen is changed from FIG. 11D, which is a screen set to be able to measure at 20 deg, to a result screen in which the measurement result is displayed on the measurement screen D0. In this way, the control unit 16 displays the calculation result of the reflection characteristic obtained in S106 on the display unit 14. Therefore, here, the measurement result screens as shown in FIGS. 11D to 11E are displayed.

  S108 is a step in which the control unit 16 determines whether to perform screen transition. Specifically, the control unit 16 determines whether or not to perform screen transition based on the screen preA or the information indicating the screen preA stored in S114. For example, when the screen preA displayed in S110 is the measurement condition setting screen (FIG. 11C), the process returns to S110 and the screen preA is displayed again. That is, the screen displayed on the display unit 14 returns from the screen of FIG. 11 (e) to the screen of FIG. 11 (c). Thereby, for example, the user can change the setting so that the measurement can be performed at, for example, 60 deg. Therefore, it is advantageous when the measurement operation and the setting operation are repeated alternately in order to determine the optimum setting such as measurement conditions. Further, since it is desired to perform comparative measurement by changing only the setting under the same conditions in as short a time as possible, it is advantageous when the measurement operation and the setting operation are alternately repeated for trial and error. Furthermore, it is possible to prevent the measurement apparatus 10 from being displaced and not being in the same condition while the operation button is pressed to move back and forth between the measurement screen and the setting screen.

  Here, the process moves from S108 to S110. However, as in the flow example 1 (FIG. 6), setting and selection may be made so that the screen returns to the screen immediately before the measurement depending on the screen (from S108 to S111). May be.)

  The order of each process in the flow examples of FIGS. 6 to 8 described above is not limited to this. The order of each step may be appropriately changed, omitted, divided, integrated, or executed in parallel during other steps. For example, S104 may be performed before S103 or before S102. If there is no adjustment or setting, S102 may be omitted. Further, the step of moving to the measurement screen in S107 and the step of displaying the result may be divided and the step of moving to the measurement screen may be performed before S105. In this case, what is displayed on the display unit 14 until the calculation result is displayed is a screen including a message indicating that measurement is in progress, for example, as shown in FIG. A flow combining the above flow examples 1 to 3 may be configured.

<6. Other examples>
In the example of FIGS. 6 to 8, the user may select the screen display after measurement in S103. For example, the following options are displayed on the screen in S103.
(A) “After measurement, return to screen A (or screen preA) / do not return”
(B) “After measurement, after returning to screen A (or screen preA) after a lapse of a predetermined time”
The user may branch at S108 or S109 by selecting a desired setting from the above options.

  Alternatively, the branch may be changed by pressing the measurement button in S103. For example, the subsequent branches may be divided depending on the time difference of the measurement button operation, such as when the button is pressed for 1 second or longer and when the button is pressed for less than 1 second. Or you may divide | segment by the difference in the frequency | count of measurement button operation like pushing once, pushing twice continuously, and half-pressing. Alternatively, it may be divided by the difference in the number of button operations, such as pressing only the measurement button, pressing the measurement button and another button simultaneously, and pressing the measurement button while another button is pressed.

  As mentioned above, although preferred embodiment of this invention was described, it cannot be overemphasized that this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
