  Hereinafter, modes for carrying out the invention will be described in detail, but the scope of the present invention is not limited to these modes.

  FIG. 1A shows an example of a waveform display device 1 to which the present invention is applied. The waveform display device 1 includes a display screen 17 on a portable main body. The display screen 17 is a touch panel as an example, and also serves as the operation unit 18. As an example, the waveform display device 1 is a measurement device that measures measurement data and displays waveforms A and B based on the measurement data on the display screen 17.

  FIG. 2 is a block diagram showing the configuration of the waveform display device 1.

  As an example, the waveform display device 1 includes a tilt sensor 10, a measurement sensor 11, a measurement unit 12, a CPU (central processing unit) 15, a display screen 17, an operation unit 18, a storage unit 19, an external I / F unit 20, And an external recording device 21.

  The tilt sensor 10 is for detecting the tilt of the display screen 17. The tilt sensor 10 is provided so as to move with the display screen 17. It is preferable to use an inclination sensor 10 that can detect not only the direction of the inclination but also the magnitude of the inclination. For example, the tilt sensor 10 is an acceleration sensor. Since the acceleration sensor can detect the direction of gravity, it can detect the inclination with respect to the direction of gravity, that is, the inclination with respect to the vertical direction. When the display screen 17 is in an upright state (reference state), that is, the tilt sensor 10 is in the top direction (upper side in FIG. 1A) is the celestial direction (upper side in the figure), and the lower part ( It is provided in such a direction as to detect that there is no inclination of the display screen 17 when the lower side of FIG. 1 (a) faces the ground direction (the ground G side shown in cross section in FIG. 1). In this example, the inclination sensor 10 detects the leftward inclination (see FIG. 1B) and the rightward inclination (see FIG. 1C) of the display screen 17, so the left and right inclinations relative to the vertical direction are detected. To detect. Therefore, any sensor that can detect at least a single-axis tilt with respect to the direction of gravity can be used as the tilt sensor 10. A detectable tilt sensor may be used.

  The measurement sensor 11 is, for example, a temperature sensor, a current sensor, a voltage sensor, a measurement probe, or the like. The measurement sensor 11 is provided in the main body, or provided by being connected to a cable outside the main body. When the measurement sensor 11 is arranged outside the main body, a connector for connecting the measurement sensor 11 to the main body may be provided. The measurement sensors 11 are provided for the measurement channels. For example, the measurement unit 12 includes an amplifier 13 that amplifies the measurement value measured by the measurement sensor 11 to an appropriate level, and an analog that performs analog / digital conversion on the amplified measurement value and outputs measurement data to the CPU 15. A digital converter 14 is provided. The measurement sensor 11 and the measurement unit 12 are the same as known measurement apparatuses.

  The CPU 15 operates according to a program stored in the storage unit 19 to control the operation of the waveform display device 1 in an integrated manner, and controls the operation of the measurement unit 12 to perform measurement, as will be described later. The waveform display processing means 30 and the scroll instruction means 31 operate.

  The display screen 17 is, for example, a liquid crystal panel that can display an image. The display screen 17 is a touch panel as an example, and the contact position on the display screen 17 can be detected. The display screen 17 also serves as the operation unit 18. In the present invention, the display screen 17 may not be a touch panel. As the operation unit 18, an operation push button (switch) may be provided.

  The storage unit 19 is a rewritable nonvolatile memory and stores a program for operating the CPU 15 and measurement data. The storage unit 19 also stores contents necessary for measurement such as measurement conditions. The storage unit 19 is, for example, a semiconductor memory such as a flash memory or a hard disk. The storage unit 19 may be divided into objects to be recorded, such as a program storage unit and a measurement data storage unit, and separate memories may be used, or a single memory may be used in common as shown in FIG. .

  The external I / F unit 20 is an interface for connecting an external device. The external I / F unit 20 is, for example, a wireless or wired LAN (Local Area Network), a modem, a USB (Universal Serial Bus), Bluetooth (registered trademark), a printer connection interface, or the like.

  The external recording device 21 is used as an external recording medium such as a portable semiconductor memory such as a USB memory or an SD (SD) memory card, or an optical disk memory such as a CD (compact disc) -R (recordable) / RW (rewritable). An external storage medium writing / reading device for recording data or reading data from an external recording medium.

  Next, the operation of the waveform display device 1 will be described with reference to FIGS. FIG. 3 is a flowchart showing the operation of the waveform display device 1.

  The CPU 15 (see FIG. 2) of the waveform display device 1 operates according to the program in the storage unit 19 when the power is turned on. The CPU 15 controls the measurement unit 12 to perform measurement, and acquires measurement data. The CPU 15 stores the acquired measurement data in the storage unit 19. This measuring operation is the same as that of the conventional measuring apparatus. Measurement data may be read from the external I / F unit 20 or the external recording device 21 and stored in the storage unit 19.

  The CPU 15 operates as the waveform display processing means 30, reads the measurement data from the storage unit 19, and displays part of the waveform based on the measurement data as waveforms A and B on the display screen 17 as shown in FIG. (Waveform display processing step S1 in FIG. 3). The waveform display processing means 30 may display the waveforms A and B in real time during the measurement, or may display the waveforms A and B by a waveform display operation by the measurer after the measurement is completed. The waveform display processing means 30 displays the measurement data such as voltage along the time axis as waveforms A and B, or performs arithmetic processing on the impedance or the like based on the measurement data of voltage and current along the time axis. Waveform display. When the waveform display device 1 performs measurement by sequentially moving the measurement probe with a moving mechanism, the waveform display device 1 may display a waveform with the measurement position as the horizontal axis. The vertical and horizontal axes for displaying the waveform, the type of graph, and the like are the same as the waveform display method of a known waveform display device, and differ depending on the measurement object and the type of measurement data. The display scale of the waveform and the data range to be displayed can be appropriately set by operating the display screen 17 (operation unit 18). The entire range of measurement data can also be displayed as waveforms A and B on the display screen 17 by setting the display scale. When a partial range of measurement data is displayed as waveforms A and B on the display screen 17 by setting the display scale (when a part of the waveform is displayed), by scrolling the waveforms A and B as described later, Waveforms A and B at arbitrary positions (measurement data range) in the entire waveform can be displayed by moving the waveform (waveform display portion) displayed on the display screen 17.

  When the waveform is displayed, the CPU 15 operates as the scroll instruction unit 31, and the waveform display processing unit 30 scrolls the waveforms A and B based on the inclination of the display screen 17 detected by the inclination sensor 10 to display the display screen 17. To display. This will be specifically described below.

  In the tilt detection step S <b> 2 shown in FIG. 3, the scroll instruction unit 31 acquires the tilt direction and magnitude (angle) from the tilt sensor 10. Subsequently, the scroll instruction unit 31 determines whether or not the acquired horizontal inclination of the display screen 17 is greater than or equal to a predetermined threshold (inclination presence / absence determination step S3). This predetermined threshold value is a threshold value for determining whether the display screen 17 is not tilted in the left-right direction (not scrolled) or tilted (scrolled). As an example, the predetermined threshold is a value of 3 ° to 30 ° as the leftward tilt angle and the rightward tilt angle of the display screen 17. If the predetermined threshold is too small, it is not preferable because it is determined that the display screen 17 is tilted when the display screen 17 is shaken due to camera shake or the like. On the contrary, if the predetermined threshold is too large, it is not preferable that the display screen 17 is not tilted unless it is largely tilted in the left-right direction.

  When it is determined in the inclination detection step S2 that the horizontal inclination is greater than or equal to the predetermined threshold, the scroll instruction means 31 proceeds to the scroll instruction step S4. In the scroll instruction step S4, the scroll instruction means 31 instructs the waveform display processing means 30 to scroll the waveforms A and B in the direction in which the display screen 17 is inclined (left direction, right direction) and the inclination. The waveform A and B are instructed to be scrolled at a speed corresponding to the size (scroll instruction step).

  For example, the scroll instruction means 31 sets the scroll speed to the minimum value when the horizontal tilt of the display screen 17 is a predetermined threshold, and the horizontal tilt of the display screen 17 is equal to or greater than a predetermined maximum value (for example, 90 °). When, the scrolling speed is set to the maximum value. Between the predetermined threshold value and the predetermined maximum value, the scroll instruction means 31 may vary the scrolling speed with a function such as a linear function (proportional), a quadratic function, or an exponential function according to the angle of inclination. Alternatively, the scrolling speed may be varied based on a predetermined speed conversion table in which the angle of inclination and the speed are associated with each other. The scrolling speed may be continuously changed by a linear function, for example, or may be changed stepwise such as 2 to 10 steps. Note that the scrolling speed may be set to a constant speed without being changed.

  As a result, in the waveform display processing step S1, the waveform display processing means 30 reads the measurement data to be scrolled (moved) and displayed from the storage unit 19 based on the instruction of the scroll instruction means 31, and the scrolled waveforms A, B is displayed on the display screen 17. For example, when the waveforms A and B are scrolled to the left, the waveform display processing means 30 reads and displays the measurement data on the left side of the waveforms A and B that have been displayed so far. The waveform display processing means 30 is scrolled at the scrolling speed designated by the scroll instruction means 31.

  While the display screen 17 is tilted leftward or rightward, the CPU 15 repeatedly executes a loop of waveform display processing step S1 to scroll instruction step S4. For this reason, the waveforms A and B are continuously scrolled and displayed in the direction of the inclination of the display screen 17 at a speed corresponding to the inclination.

  When the measurer wants to stop scrolling the waveforms A and B, the measurer returns the display screen 17 to a straight state (neutral position). When the inclination of the display screen 17 disappears, it is determined in the inclination presence / absence determination step S3 that the magnitude of the inclination is smaller than a predetermined threshold, and the process returns to the inclination detection step S2. As a result, no scrolling instruction is issued to the waveform display processing means 30, so that the scrolling is immediately stopped, and the waveforms A and B are stopped in the state of being displayed at that time.

  FIG. 1B shows a state in which the display screen 17 (waveform display device 1) is tilted to the left. In this state, the waveforms A and B continue to scroll in the left direction and are displayed as indicated by white two-dot chain arrows in FIG. FIG. 1C shows a state where the display screen 17 (waveform display device 1) is tilted to the right. In this state, the waveforms A and B continue to scroll in the right direction and are displayed as indicated by white two-dot chain arrows in FIG. As shown in FIG. 1A, when the display screen 17 is returned to the state where it is not tilted, the scrolling of the waveforms A and B is stopped.

  Thus, the waveforms A and B can be scrolled by a simple operation of tilting the display screen 17. Since the display screen 17 may be tilted in the direction in which the waveforms A and B are desired to be scrolled, the operation is easy to understand intuitively and the operability is good.

  Note that once the display screen 17 is tilted leftward (rightward) and the waveforms A and B begin to scroll, the scrolling will not stop and continue to scroll even if the display screen 17 is returned to the neutral position. Also good. In this case, for example, the scrolling is stopped by tilting the display screen 17 in the reverse direction, tapping the display screen 17, or pressing a stop button.

  Further, it is preferable that the predetermined threshold value for starting the scrolling can be set to an arbitrary value or to be selectable from several values by the operator's operation. In this case, the predetermined threshold may be set to zero. Further, the waveform presence / absence determination step S3 in the flowchart of FIG. 3 may be omitted, and the waveform may be scrolled when the display screen 17 is tilted even a little without comparing the predetermined threshold value with the magnitude of the tilt. In addition, in the inclination presence / absence determination step S3, a hysteresis characteristic may be given to the comparison with the predetermined threshold value.

  Moreover, you may use the geomagnetic sensor which can detect the direction of east-west north-south (north-south) as an inclination sensor. Moreover, you may use combining an acceleration sensor and a geomagnetic sensor as a tilt sensor. When used in combination, it is possible to detect the direction of inclination in more various directions and to improve the detection accuracy.

  Moreover, although the waveform A and B demonstrated the example scrolled in the left-right direction, you may make it scroll a waveform up and down. When scrolling up and down, for example, the waveform may be scrolled upward when the display screen 17 is tilted leftward, and the waveform may be scrolled downward when tilted rightward. In addition, when scrolling in the vertical direction, the tilt sensor 10 is provided so that the tilt in the front-rear direction of the display screen 17 can be detected, and the waveform is scrolled upward when the display screen 17 is tilted to the measurer side (front). The waveform may be scrolled downward when tilted to the opposite side (back) of the measurer. When the waveform scrolls up, down, left, and right, the waveform may be scrolled with the tilt of the display screen 17 in the front, back, left, and right directions.

  The inclination of the display screen 17 and how the waveform is scrolled may be determined as appropriate. Furthermore, it is preferable that the measurer can set the direction in which the waveform is scrolled when the display screen 17 is tilted by operating the operation unit 18. It is preferable to use a two-axis tilt sensor or a three-axis tilt sensor as the tilt sensor 10 because the movement of the waveform scroll can be defined in accordance with various movements of the xyz axis of the display screen 17.

  For example, FIG. 4A shows a side view of the waveform display device 1a with the reference screen when the display screen 17 is in a horizontal state facing the sky. In this waveform display device 1a, as shown in FIG. 4A, the tilt sensor 10 is such that the display screen 17 (upper side of FIG. 4A) faces the sky (upper side of the figure) and the rear surface of the display screen 17 When detecting that the display screen 17 is not inclined when the state (the lower side in FIG. 4 (a)) faces the ground direction (the ground G side shown in cross section in FIG. 4) (reference state). The waveform display device 1a is provided. FIG. 5 shows a plan view of the waveform display device 1a. FIG. 5 is a diagram illustrating a state in which the waveform display device 1a illustrated in FIG. 4A is viewed in the direction indicated by the alternate long and short dash line P in FIG. 4 (the direction in which the ground direction is viewed from the celestial direction). 4A is a diagram illustrating a state in which the waveform display device 1a is viewed from the direction indicated by the alternate long and short dash line Q in FIG.

  In this example, when the tilt sensor 10 detects the tilt in the left direction of the display screen 17 shown in FIG. 4B, the scroll instruction means 31 has a waveform A in the L direction indicated by a white two-dot chain line in FIG. , B is scrolled. On the other hand, when the tilt sensor 10 detects the rightward tilt of the display screen 17 shown in FIG. 4C, the scroll instruction means 31 moves the waveforms A, R in the R direction indicated by white two-dot chain lines in FIG. Scroll B.
