Document Type and Number:
Japanese Patent JP2820938
Kind Code:
B2
Abstract:
PURPOSE:To inhibit the reading actions performed for the duplication purpose by storing previously the data on execution of a program and inhibiting the program reading job in the case no coincidence is obtained between the program and said data. CONSTITUTION:The executing order address, etc., of a user program of a 1st memory 42 are stored in a 3rd memory 66. In a program reading mode, a control program stored in a 2nd memory 38 is first read and the user program of the memory 42 is sequentially read in response to the execution of the control program. Then the data on the address, etc., of the read-out user program is compared with the data stored in the memory 66. Thus the access is inhibited to the memory 42 in the case no coincidence is obtained between both data. As a result, the user program can be read out only for the due purpose.
