    • A program replacement device is incorporated in a computer system having a CPU and a program memory in which first programs to be executed by the CPU are stored. The program replacement device includes a RAM employed as the program memory and having a write enable terminal, and a protection circuit interposed between the write enable terminal of the program memory and a write signal outputted from the CPU. The protection circuit includes a push switch for instructing program replacement with respect to the program memory, a pulse generating circuit for generating a pulse signal having a given time interval in response to an instruction from the push switch, and a gate circuit for making, only when the pulse signal is generated, the write signal outputted from the CPU valid with respect to the write enable terminal of the program memory. The program replacement device further includes an interruption generating circuit for generating in the CPU an interruption required to write second programs in the program memory in response to the instruction from the instruction section, thereby replacing the first programs by the second programs.
    • 程序更换装置被结合在具有CPU和程序存储器的计算机系统中,其中存储有要由CPU执行的第一程序。 程序更换装置包括用作程序存储器并具有写使能端的RAM,以及插入在程序存储器的写使能端和从CPU输出的写信号之间的保护电路。 该保护电路包括用于指示程序存储器的程序替换的按钮开关,用于响应于来自按钮开关的指令产生具有给定时间间隔的脉冲信号的脉冲发生电路,以及仅用于制造的门电路 当产生脉冲信号时,从CPU输出的写入信号相对于程序存储器的写使能端有效。 程序更换装置还包括中断产生电路,用于响应于来自指令部分的指令,在CPU中产生写入程序存储器中的第二程序所需的中断,从而由第二程序代替第一程序。

    • Disclosed is a copying system wherein operation modes of a copying machine are set using an IC card located at a distance from the copying machine. The IC card has: a transmitter for transmitting a signal that contains an identification code for identifying the IC card itself, an identification code for identifying the copying machine, and prestored operation mode setting information for the copying machine; a receiver for receiving a signal transmitted from the copying machine; and a CPU for identifying the copying machine and its operating condition. The copying machine has: a transmitter for transmitting a signal that contains an identification code for identifying the copying machine itself, an identification code for identifying the IC card, and information concerning the operating condition of the copying machine itself; a receiver for receiving a signal transmitted from the IC card; and a CPU for identifying the originating IC card and for setting the copying machine operation mode.
