Abstract

PURPOSE:To evade the double working of a data processor after the reapplication of a power supply by providing an address pointer to show the stored position of the data on the operation carried out at present by a machine on an IC card and restarting the operation according to the address value of the address pointer when the operation is restarted with the reapplication of the power supply of a data processor. CONSTITUTION:An address point is set at a part of an IC card 2 to show the data with which a machine 1 is working. The machine 1 sets the head address of the working data to the address pointer when the machine 1 reads the data out of the card 2. If a power supply is cut due to an instantaneous power failure, etc., while the machine 1 is working by reading successively the stored data, the machine 1 reads the data on the storage address shown by the address pointer and starts its operation after the reapplication of a power supply. Thus the machine 1 can start the operation in the state set right before the stop of the machine 1 after the reapplication of the power supply even if the power supply is cut due to an instantaneous power failure, etc.

適用されるデータ処理装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to, for example, programmed operation of industrial robots, etc.
The present invention relates to a data processing device applied to a machine that operates using data stored in an IC card.

している。[Prior Art] In a machine that operates using data stored in an IC card, when the machine is operating by sequentially reading the stored data, the power is cut off due to a momentary power outage, etc. In this case, it is impossible to know what data was being used for operation at the moment it stopped. Therefore, after the power is turned on again, the device operates by reading data from the beginning of the stored data.

After the power is turned on again, the system returns to the first process and starts a duplicate operation, making it impossible to restart the operation from the state immediately before stopping.

地のデータから読み込んで動作を行なう。[Means for Solving the Problems] According to the present invention, an address pointer is set in a part of the IC card to indicate which data the machine is using to operate. When the machine reads data from the IC card, it sets the start address of the data being used in the address pointer. If the power is cut off due to an instantaneous power failure while the machine is operating by sequentially reading stored data, after the power is turned on again, the machine reads data from the memory address indicated by the address pointer and performs the operation.

Therefore, if the power is cut off due to an instantaneous power failure while the machine is operating by sequentially reading stored data, the machine will read the data indicated by the address pointer and perform the operation after turning the power back on. Therefore, the operation can be started from the state immediately before stopping.
