    • A data reception system includes a data acquisition unit acquiring data from a predetermined transmission path, an access control unit storing the data acquired by the data acquisition unit in a predetermined storage area, and a plurality of storage areas. The plurality of storage areas includes a first storage area and a second storage area having a greater storable capacity and a lower storing speed compared to the first storage area. The access control unit further includes a transfer unit. The access control unit determines whether the total amount of data stored in the first storage area is in the excess of a predetermined threshold or not and causes a transfer unit to transfer the data acquired by the data acquisition unit to the second storage area to store the data in the second storage area when the total amount is in the excess of the threshold.

    • An impact-type electronic printer uses a rotary printing wheel and a ROM to store printing-type position data for dealing with respective printing types borne by the rotary printing wheel, hammer pressure data, and the spacing data respectively matching the designated printing types together with printing-type position data. The main CPU then draws out the printing-type position data, hammer pressure data, and the spacing data in response to the input data to allow the printer to execute the printing operation using the designated printing types in accordance with these data drawn out of the ROM, thus realizing distinctly clean printed characters. The unique system embodied by the present invention makes it possible for the controller to easily read important data from the ROM. In other words, since the control system reflecting the present invention allows the ROM to effectively store the printing-type position data, hammer pressure data, and the specifying data in two words, the control system can, for example, securely read the data merely by executing the reading operations twice.
    • 冲击型电子打印机使用旋转印刷轮和ROM来存储用于处理由旋转印刷轮承载的各种印刷类型,锤压数据和分别与指定印刷类型匹配的间隔数据的印刷位置数据以及 打印型位置数据。 然后,主CPU根据输入数据抽出打印类型的位置数据,锤击数据和间隔数据,以使打印机能够根据这些数据中的指定的打印类型执行打印操作 ROM,从而实现清晰的打印字符。 由本发明实现的独特系统使得控制器能够容易地从ROM读取重要的数据。 换句话说,由于反映本发明的控制系统允许ROM以两个字有效地存储打印位置数据,锤压数据和指定数据,所以控制系统可以例如仅安全地读取数据 通过执行两次读取操作。
