In this embodiment, in the initial state, display is performed with a preset set value. These initial setting values can be changed in each timeline unit 110 and event detail display unit 170, and the changed setting values are displayed in real time.

  That is, circular timeline change buttons 114 are provided at both ends of the time bar 113, and the timeline change button 114 is dragged from the state of FIG. 6A, as shown in FIG. 6B. When it is moved to an arbitrary position on the event timeline 112a (step 514), the control device 6 determines that the time condition of the event 30 has been changed, and sets it as the time condition of the selected event 30 (step 516). ).

  Further, in this embodiment, the control device 6 displays various detailed setting display button groups 171 stored in the storage device 7 corresponding to the selected event. For example, in the state of FIG. 6A, as “event B occurrence”, a numerical value display unit 172 is provided on one side, and a numerical value setting unit 173 and a switch group 175 are provided on the other side. The control device 6 monitors whether or not the numerical value setting unit 173, which is an event detail change button, has been clicked (step 518), and an arbitrary numerical value can be selected from the respective pull-down buttons of the upper limit setting unit and the lower limit setting unit of the numerical value setting unit 173. By setting, the contents of the search condition can be changed as shown in FIG. The set value is displayed in real time with the corresponding change numerical value reflected in the numerical value display unit 172 (step 520). Here, the switch group 175 includes an OK button that receives the changed numerical value, a cancel button that returns the numerical value, and an apply button that applies the changed numerical value to all.

  The control device 6 also monitors whether or not the event-button 142 has been clicked (step 522). When the event-button 142 is clicked, the control device 6 executes the deletion of the event 30 in the selected state in the event display unit 140 (step 524). When deleting, a guidance is displayed to confirm the deletion again.

  Further, when a plurality of events 30 are displayed on the event display unit 140, the control device 6 monitors whether or not another event 30 has been selected (step 526). When another event 30 is selected, the control device 6 changes the detailed setting display button group 171 of the event detail display unit 170 to the one corresponding to the selected event 30 (step 528).

  In this embodiment, any one of the events 30 input to the event display unit 140 is in a selected state, and the detailed contents of the selected event 30 are displayed on the event detail display unit 170. In the state shown in FIG. 6, one event 30 is input. However, in the state where a plurality of events 30 are input as shown in FIG. 7, other events 30 displayed on the event display unit 140 are displayed. By selecting, the detailed contents can be displayed on the event detail display section 170, so that the detailed setting value can be changed or the event itself can be deleted.

  Next, the control device 6 monitors whether or not the search expression display unit 150 is clicked with the mouse 4 and a search expression is input through the keyboard 5 (step 530). When a search expression is input, the search expression is stored in the internal memory (step 532).

  On the other hand, since the search formula is not input and the process returns to step 508, the event + button 141 can be operated again to set a plurality of events 30. FIG. 7A shows a state in which a plurality of events 30 are input, and FIG. 7B shows a state in which a search formula is set in the search formula display unit 150.

  The control device 6 monitors whether or not the search button 151 is clicked (step 534). When the search button 151 is clicked from the state of FIG. 7B, it is determined whether or not the search expression is valid. (Step 536) If the search formula is not valid, a warning guidance is displayed and re-input of the search formula is accepted. On the other hand, when the search expression is valid, as shown in FIG. 8, a predetermined database is accessed and the result is displayed on the search result display unit 160 in real time. In this embodiment, in the initial state, the number of hits is displayed on the search response display unit 161 (step 538). In this state, the output format of the search result displayed on the search content display unit 162 such as a list display or a graph display can be set from the pull-down menu of the output format selection unit 163 (step 540). When the control device 6 accepts an operation of the output button 164 (step 542), the output format set by the output format selection unit 163 is displayed in real time on the search content display unit 162 (step 544).
