    • A magnetic recording reproducing apparatus is made ready to operation by insertion thereto of a pack housing an endless recording medium. When a magnetic card is inserted into the apparatus with the pack inserted thereto, the contents, informations or data recorded on the magnetic card are read out and recorded on the endless recording medium and then the recorded contents, informations or data are reproduced from the endless recording medium. After passage of the magnetic card through the apparatus, the reproduction from the endless recording medium will repeatedly continue. When a magnetic card is inserted into the apparatus without any pack inserted thereto, a direct reproduction from the magnetic card is performed. When another type of a pack housing an endless recording medium having a longer playing time period is inserted into the apparatus, the reproduction from the recording medium can be effected, and any information transfer from the magnetic card to the recording medium cannot be performed and any direct reproduction from the magnetic card cannot be effected.
    • 磁记录再现装置准备好通过插入到容纳无端记录介质的包装盒中进行操作。 当将磁卡插入装置中插入包装盒时,将记录在磁卡上的内容,信息或数据读出并记录在环形记录介质上,然后将记录的内容,信息或数据从无尽的 记录介质。 在磁卡通过设备之后,来自环形记录介质的再现将重复地继续。 当将磁卡插入到装置中而没有插入任何包装时,就执行从磁卡的直接再现。 当将具有较长播放时间段的环形记录介质的其他类型的包装插入到设备中时,可以实现从记录介质的再现,并且不能执行从磁卡到记录介质的任何信息传送,并且任何 从磁卡的直接再现不能实现。

    • The recorded content of a magnetic card is transferred directly to a magnetic tape simply by bringing the magnetic card into contact with the magnetic tape and applying a magnetic field to the contacting area with the aid of a copy magnet or a magnetic printing head energized by D. C. current or A. C. current, on the condition that the coercive force of magnetic material on the card is larger than that on the tape, and a reproducing head mounted along the path of the tape reproduces the transferred content. Thus, the recorded content of a magnetic card can be reproduced many times just by engaging the card in the device once.
    • 磁卡的记录内容可以简单地通过使磁卡与磁带接触而直接传送到磁带,并借助复制磁体或通过DC通电的磁性打印头向接触区域施加磁场 电流或AC电流,条件是磁卡上的磁性材料的矫顽力大于磁带上的矫顽力,并且沿磁带路径安装的再现头再现传送的内容。 因此,只要通过将卡片卡在设备中一次就可以多次再现磁卡的记录内容。

    • To prevent image defects such as fog and irregularities caused by the accumulation of the oppositely charged toner by flying the toner toward a photoreceptor to compulsorily consume the toner even though the toner is oppositely charged toner having a small charged amount. A potential difference between the photoreceptor and the development roller is set at a value at which the normally charged toner on the development roller can be flown toward the photoreceptor in the development phase at the time of compulsorily consuming the toner, and this potential difference is set at a value at which the flown normally charged toner can be returned to the development roller in the recovery phase. A development duty and a frequency f are set in such a way that a time period in the development phase is larger than a time taken for the normally charged toner on the development roller to fly to a point located midway between the development roller and the photoreceptor and is smaller than a time taken for arriving at the photoreceptor, and a time period in the recovery phase is larger than a time taken before the normally charged toner arrived at the point located midway between the development roller and the photoreceptor arrives at the photoreceptor, returns to the development roller to beaten out the oppositely charged toner and the oppositely charged toner beaten out flies to the photoreceptor.
    • 为了防止由于相反充电的调色剂的积聚引起的图像缺陷,例如通过将调色剂朝向感光体飞行而强制消耗调色剂,即使调色剂具有相反电荷的带电量小的调色剂。 感光体和显影辊之间的电位差被设定为在强制消耗调色剂时显影辊上的正常带电的调色剂能够在显影阶段中朝向感光体流动的值,并且设定该电位差 在正常充电的调色剂可以在恢复阶段返回到显影辊的值。 显影负荷和频率f被设定为使得显影阶段的时间段大于显影辊上的正常充电的调色剂飞行到位于显影辊和感光体之间的位置的时间 并且小于到达感光体所需的时间,并且恢复阶段的时间段大于在正常充电的调色剂到达位于显影辊和感光体之间的位置到达感光体的时间, 返回到显影辊,以殴打带相反电荷的调色剂,并将带相反电荷的调色剂扑灭到感光体中。
