SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a tool system in which the magnitude relationship between a target value and a threshold value can be intuitively grasped and the operation of inputting the target value and the threshold value is simple.

That is, a tool system according to the present invention comprises a measuring tool, and a display device connected to the measuring tool and having a display, wherein the display device displays on the display a measurement value measured by the measuring tool. a slider display unit for displaying a target value slider for inputting a target value, and a threshold slider for inputting a threshold value indicating at least one of the upper limit and the lower limit of the allowable range of the measured value, the slider display unit displays the target value slider and the threshold slider separated by a distance corresponding to the difference between the target value and the threshold, and when the difference is zero, the target value slider and the threshold slider and are displayed so as not to overlap each other.

In this case, a target value slider for inputting a target value and a threshold slider for inputting a threshold indicating at least one of the upper limit or lower limit of the allowable range of measured values are displayed on the display. Since the target value and the threshold value are input by the target value slider and the threshold slider, the target value and the threshold value can be input simply by sliding the target value slider and the threshold value slider. It becomes simple.

Further, since the slider display section is configured to display the target value slider and the threshold slider separated by a distance corresponding to the difference between the target value and the threshold value, the positional relationship between the target value slider and the threshold slider The magnitude relationship between the target value and the threshold can be intuitively grasped, and erroneous input can be prevented.

Furthermore, when the difference between the target value and the threshold value is zero, the slider display section is configured to display the target value slider and the threshold slider so that they do not overlap. It becomes simple. More specifically, for example, in a tightening tool (measuring tool), a target value of tightening torque (measured value) and threshold values indicating the upper and lower limits of the allowable range of tightening torque are set. Since the target value and the threshold value are both numerical values that change depending on the tightening object, the target value slider for setting the target value and the threshold slider for setting the threshold value can be easily distinguished from each other. is indicated by a symbol (for example, O, △, etc.) having a width in the moving direction (sliding direction). In this case, if the target value slider and the threshold slider are displayed overlapping each other, it becomes impossible to accurately specify the slider to be slid. Therefore, a separate operation is required to designate the slider to be slid, and multiple operations are required to change the target value or the threshold value. Therefore, if the target value slider and the threshold value slider are displayed so as not to overlap each other as in the present invention, the operation for specifying the slider becomes unnecessary, and the input operation becomes simpler to the extent that the operation becomes unnecessary. .

Further, as a specific configuration of the slider display section, when the difference is zero, the slider display section displays the target value slider and the threshold slider in contact with each other.

With such a configuration, when the target value slider and the threshold value slider come into contact with each other, it can be intuitively grasped that the target value and the threshold value are the same.

Also, when tightening a plurality of objects to be tightened, there are cases where only the target value is changed according to the object to be tightened, and the tightening work is performed without changing the difference between the target value and the threshold value. Therefore, when the user performs an input operation to slide the target value slider, the slider display unit displays the threshold value together with the target value slider without changing the distance between the target value slide and the threshold value slider. It may be displayed by sliding a slider.

With such a configuration, even if the target value is changed by sliding the target value slider, the difference between the target value and the threshold does not change, and there is no need to reset the threshold in the tightening work.

In addition, the display device includes a measurement condition display unit that displays the set target value and the threshold value together with the target value slider and the threshold value slider on the display, and a user's target value slider and the threshold value slider. and a measurement condition setting unit that sets the target value and the threshold value input based on the input operation to the measurement condition display unit.

With such a configuration, since the target value and the threshold are displayed together with the target value slider and the threshold slider, the magnitude relationship between the target value and the threshold can be intuitively grasped from the positional relationship between the target value slider and the threshold slider. Furthermore, an accurate numerical value can be grasped from the target value and the threshold value.

Further, the display device further includes a numerical input area display unit that displays a numerical input area for numerically inputting the target value and the threshold value, and the measurement condition setting unit performs an input operation on the numerical input area by a user. The target value and threshold value input based on the measurement condition display unit are set in the measurement condition display unit, and the slider display unit sets the target value slider and the threshold slider to the target set by the measurement condition setting unit They may be displayed with a distance corresponding to the difference between the value and the threshold.

With such a system, it becomes possible to input numerical values for target values and thresholds. When numerical values are input, the magnitude relationship between the target value and the threshold can be intuitively determined from the positional relationship between the target value slider and the threshold slider. can be comprehended.

The display device may be provided separately from the measuring tool and may be connected to the measuring tool wirelessly or by wire. With such a device, the display device can be separated from the measuring tool, so that the measuring tool can be miniaturized. This reduces the weight of the measuring tool and reduces the burden on the user.

Also, the display device may have a touch display.

Further, a tool system program according to the present invention is a program used in a display device connected to a measuring tool and having a display, wherein target values of measured values to be measured by the measuring tool are input on the display. and a threshold value slider for inputting a threshold value indicating at least one of the upper limit or the lower limit of the allowable range of the measured value. wherein the slider display unit displays the target value slider and the threshold slider separated by a distance corresponding to the difference between the target value and the threshold, and when the difference is zero, the target It is characterized in that the value slider and the threshold slider are displayed so as not to overlap each other.

According to the present invention configured in this way, the magnitude relationship between the target value and the threshold can be intuitively grasped, and the operation of inputting the target value and the threshold is simplified.

Each slider SD has a width in the moving direction so that the user can easily touch it. Specifically, for example, each slider SD has a shape such as ◯, Δ, □, etc., having a width in the moving direction and in the direction orthogonal to the moving direction. In this embodiment, the target value slider SD1 has a circle shape, and the upper limit value slider SD2 and the lower limit value slider SD3 have a triangle shape. Therefore, the target value slider SD1 and the upper limit value slider SD2 are in point contact when the difference between the target value and the upper limit value becomes zero. Further, the target value slider SD1 and the lower limit value slider SD3 are in point contact when the difference between the target value and the upper limit value becomes zero.

Numerical values corresponding to the measuring range of the measuring tool 10 are assigned to the line L along the longitudinal direction. As a result, the numerical values assigned to the positions of the sliders SD on the line L are input as the measurement condition values. Therefore, when the user performs an input operation to slide each slider SD along the line L, the numerical value assigned to the position of each slider SD after movement with respect to the line L is input as each measurement condition value.
