PURPOSE:To eliminate the operating troubleness by subtracting the time required for a different work item already inputted from the time counted by a timer at the present time point when the time necessary for work is recorded and displaying the time obtained by the subtracting process a the initial value. CONSTITUTION:The corresponding work item and its setting signal supplied via a keyboard 1h are transmitted to an arithmetic unit 1a and stored temporarily in an editing data memory area of a memory 1c via the setting signal. Then the unit 1a receives the count value of a clocking timer device 1b from this device 1b at the present time point. The time necessary for another work item already inputted and received from the memory 1c is subtracted from the count value of the device 1b. This time obtained from the subtracting process is displayed at a necessary work time display part for work items of a display device 1g via a data line 1i and an output interface 1e as the initial value of the work necessary time of the corresponding work item. Thus the timing job and the time calculating job can be omitted. |
