PURPOSE:To gather operation data on a working machine securely by a simple device and to perform specific arithmetic and display the data by providing a programmable logic controller and a printer in one body. CONSTITUTION:The working machine 10 is provided with the known programmable logic controller(PLC) 12 and the printer 14 which prints the output of the PLC 12 and the PLC 12 and printer 14 are stored in one case body 16. The PLC 12 inputs data on the operation time and working time of the working machine 10 and calculates the operation rate and working rate of the working machine 10. Then the printer 14 prints out the operation time and working time, and the operation rate and working rate. Namely, the PLC 12 and printer 14 are stored in the one case body 16, so they can easily be carried and fitted to a new working machine or existent working machine. |
