    • A thermal head drive circuit with the input connected to a source of printing data and the output connected to a thermal head including heater elements, so as to improve the picture quality of a thermal head recording apparatus for printing successive lines. Improved picture quality is effected by using data from previously printed lines to compute a corrected pulse energy for the line being printed. The circuit uses a heat storage state operator for operating the heat storage state of each of the heater elements constituting a thermal head, a pulse energy operator for computing a printing pulse energy to be applied to each of the heater elements, a memory for storing the electrical pulse energy used in the previously printed line, and a counter to count the number of dots on the line to be printed. The pulse energy operator uses data from the heat storage state operator, the counter, and from the memory which has data on the pulse energy used in previously printed lines. The output of the pulse energy operator is connected to a pulse generator which is used to drive the heater elements of a thermal head.
    • 一种热敏头驱动电路,其输入端连接到打印数据源,输出端连接到包括加热器元件的热敏头,从而提高用于打印连续线的热敏头记录装置的图像质量。 通过使用来自先前打印的线的数据来计算改进的图像质量,以计算正在打印的线的校正脉冲能量。 电路使用蓄热状态操作器来操作构成热敏头的各个加热元件的蓄热状态,用于计算要施加到每个加热器元件的打印脉冲能量的脉冲能量算子,存储器 在先前打印的线中使用的电脉冲能量,以及计数要打印的线上的点数的计数器。 脉冲能量运算符使用来自储热状态运算符,计数器和存储器中的数据,存储器具有关于以前打印的线中使用的脉冲能量的数据。 脉冲能量运算器的输出端连接到用于驱动热敏头的加热元件的脉冲发生器。

    • An image input/output device having a device body with an operating panel and a controlling computer section comprising a central processing unit, a read-only memory a random access memory and a bus line for transmitting data therebetween. An input/output control section connects the controlling computer section and the device body to each other. A start/stop switch is provided on said operating panel. The computer determines (1) whether or not the device body is in operation, (2) whether or not said device body is connected through a line to an outside device, and (3) whether or not an original is set at a predetermined position. When the start/stop switch is operated, according to outputs of the computer, the device is stopped, or a specific mode copying, signal receiving or a signal transmitting is selected, so that the device is automatically operated in the mode thus selected.
    • 一种图像输入/输出装置,具有具有操作面板的装置主体和包括中央处理单元,只读存储器随机存取存储器和用于在其间传输数据的总线的控制计算机部件。 输入/输出控制部分将控制计算机部分和装置主体相互连接。 在所述操作面板上提供启动/停止开关。 计算机确定(1)设备主体是否在运行,(2)所述设备主体是否通过线路连接到外部设备,以及(3)原件是否设置在预定位置 。 当启动/停止开关被操作时,根据计算机的输出,设备停止,或者选择特定模式复制,信号接收或信号发送,使得设备在如此选择的模式下自动操作。
