    • A power source system failing to become operable when only a primary A.C. power source is turned on, and made operable by turning on not only the primary A.C. power source but also a secondary power source is disclosed, in which initial-state-of-secondary-source setting means is previously set so that the initial state of the secondary power source at a time when the primary A.C. power source is turned on, is a desired one of an ON-state and an OFF-state, a system control part reads out the state of the initial-state-of-secondary-source setting means immediately after the primary A.C. power source has been turned on, and an ON-OFF control is performed for an ON/OFF switching circuit in accordance with the read-out state, to make the initial state of the secondary power source equal to the desired state. Thus, in a case where a controlled apparatus is required to become operable as soon as the primary A.C. power source is turned on, the initial-state-of-secondary-source setting means is set so that the initial state of the ON/OFF switching circuit is an ON-state, to make the controlled apparatus usable immediately without operating any operation switch, thereby improving the usability of the controlled apparatus.
    • 当只有一次交流电源接通时,电源系统不能起作用,并且通过不仅接通主交流电源而且通过次级电源可以操作,其中初始次级 源设定装置被预先设定为使得在主交流电源接通时次级电源的初始状态是导通状态和断开状态期望的一个,系统控制部分读取 在初级交流电源已经接通之后紧接着初始状态二次源设定装置的状态,并且根据读出的ON / OFF切换电路进行ON-OFF控制 状态,以使次级电源的初始状态等于期望状态。 因此,在主电源接通的情况下,要求受控装置变得可操作的情况下,初始状态二次源设定装置被设定为使得开/关的初始状态 开关电路是导通状态,使得受控设备可以立即使用而不需要操作任何操作开关,从而提高受控设备的可用性。

    • A thermal ink-transfer printer is disclosed in which an ink donor sheet is wound on a supply reel. The ink donor sheet is drawn out from the supply reel and passes between a rotating drum and a thermal head and is then rolled round a winding reel. Printing paper is moved in a printing-paper transporting path formed between the rotating drum and guide means. The thermal head presses the ink donor sheet against the printing paper and heats the ink donor sheet to transfer the ink on the ink donor sheet to the printing paper. The ink donor sheet after completing the ink transfer is separated from the printing paper and rolled round the winding reel. The printing paper separated from the ink donor sheet is moved in the printing-paper transporting path. When the ink donor sheet during separation from the printing paper is erroneously drawn into a predetermined portion of the printing-paper transporting path, this erroneous operation of the ink donor sheet is detected by jam detecting means.
    • 公开了一种热转印打印机,其中供墨片卷绕在供带盘上。 供墨片从供带盘上拉出,并在转鼓和热敏头之间通过,然后卷绕在卷绕卷轴上。 打印纸在形成在旋转滚筒和引导装置之间的打印纸传送路径中移动。 热敏头将供墨器薄片压在打印纸上并加热供墨片,将供墨片上的墨水转印到打印纸上。 完成油墨转印后的供墨板片与印刷纸分离并在卷绕卷轴上滚动。 与供墨片分离的打印纸在打印纸传送路径中移动。 当从打印纸分离期间的供墨器片被错误地吸入打印纸传送路径的预定部分中时,通过卡纸检测装置检测供墨板的这种错误操作。
