    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 translation: 冲击线打印机设置有字符鼓，其字符和数字在其外围表面上具有字符和数字，并且打印锤与字符鼓相对，其中打印纸在字符鼓和打印锤之间通过。 打印机还设置有从动轴，摩擦盘安装在从动轴上。 设置有轮构件，每个轮构件与每个摩擦盘相对并且通常间隔开。 轮构件选择性地与摩擦盘接触以致动所选择的打印锤以在打印纸上进行打印。 打印锤通常通过例如通过弹簧偏压以远离字符鼓。

    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: In a recording apparatus using a plurality of kinds of head cartridges each comprising an ink jet recording head and an ink tank formed as a unit, the present invention prevents, when a wrong head cartridge has been mounted during cartridge exchange, data regarding the remain of ink in a thitherto used cartridge of other kind from being lost, and enables the remain of ink in that cartridge to be confirmed. A user is pressed for the exchange of the head cartridge now mounted to thereby effect the exchange actually, and is called on to confirm whether the newly mounted head cartridge is a right one, and the initialization of the data regarding the remain of ink is effected when the user has done the inputting of the confirmation.

    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.

    Abstract: A thermal printer is capable of maintaining the heating elements thereof at a constant temperature to achieve uniform print density and to avoid abnormal heating of the heating elements. For this purpose each heating element receives a stronger driving pulse at the first printing operation in a scan line and receives a weaker driving pulse at the subsequent printing operation.

    Abstract: A thermal transfer printer includes a thermal head having plural heat generating elements, a thermal head driver connected to a character generator for controlling the thermal head by supplying drive currents to the heat generating elements of the thermal head in response to print information, and control circuit for controlling the drive currents from the thermal head driver in response to the ambient temperature. Therefore, the thermal transfer printer is capable of constantly providing an optimum transfer density regardless of the ambient temperature, thus ensuring a satisfactory print quality.
