    Abstract: A thermal head has heating resistors for thermal image recording and a lift-off heating resistor for ink lift-off. In image recording, both resistors are energized to maintain the ink adhesive to a recording sheet until an ink ribbon is separated from the recording sheet. In the lift-off operation, only the former resistors are energized but the latter positioned behind is deactivated, so that the ink already deposited on the sheet adheres to the ink ribbon, is cooled due to the deactivation of the latter resistor and is lifted off by the ink ribbon.

    Abstract: An impact line printer is provided with a character drum which has characters such as letters and numerals on the peripheral surface thereof and printing hammers in opposite to the character drum, wherein a printing paper is passed between the character drum and the printing hammers. The printer is further provided with a driven shaft on which is mounted frictional discs. Wheel members are provided, each of which is opposed to and normally spaced apart from each of the frictional discs. The wheel members are selectively brought into contact with the frictional discs to actuate selected printing hammers to effect printing on the printing paper. The printing hammers on normally biased for example by means of spring to keep away from the character drum.

    Abstract: The present invention relates to a discharge recovery processing of an ink jet recording apparatus which forms an image on the recording medium by discharging the ink. The invention aims to prevent the increase in the running costs and the shortened life of a waste ink tank by preventing the wasteful ink consumption which may be caused by the dual use of an automatic recovery processing and a manual recovery processing after the replacement of an ink tank. Also, the invention further aims to provide an ink jet recording apparatus with high safety and reliability as well as effecting an appropriate recovery by controlling the movement of head in involving the recovery.

    Abstract: A recording apparatus for recording by discharging plural kinds of ink from the recording head to a recording medium comprises detection means for detecting the decrease of ink remains of each ink of the plural kinds of ink, ink amount indication means arranged in a number smaller than the number of the plural kinds of ink, and signal outputting means for outputting signals which enables the decrease of ink remains having the least amount of ink remains to be displayed on the ink amount indication means in accordance with the results of plural detections by the detection means. In this way, only the ink remains having the least ink remains among those kinds of ink in use is indicated on the display, not the ink remains of all the kinds of ink, thus making it possible to minimize the number of indication means to make the indication device simpler and smaller or minimize the area on the screen of the display assigned for indicating the ink remains in order to save it for indicating more information other than the ink remains.
