    on the housing and in its channel cavity with the channel of the housing, a replaceable ink tank installed in the housing, a tube of elastic elastic material in the bottom, through which the needle passes into the cavity of the tank, and means for fixing and fixing the position of the tank in the housing, the channel cavity in | The needle consists of a central deaf channel and, in conjunction with it, and located perpendicular to its hole, the diameter of which is less than the thickness of the reservoir plug, and the means of fastening and fixing the position of the reservoir. in the housing consists of a guide groove made in the housing, radially around the needle and having two stepped sections, and a finger mounted on the reservoir, which is located in the guide groove of the housing.
     FIG. 1 shows the proposed printing unit of the device for recording information with ink jet; Figure 2 is the same in the position where the reservoir is in the neutral position and ink supply to the working chambers is stopped; in fig. 3 - the same, in the position when the tank is in the working position - in FIG. 4 - interaction of a hollow needle with an elastic stopper of a bottom of the tank.
    The printing unit of the device for recording information with an ink jet contains a writing head including a body 1 in which there is a channel 2 for supplying ink to working chambers (not shown) and a cannula 3 mounted on the body 1 mounted in the body 1 of an interchangeable ink reservoir 4 having a resilient elastic material in the bottom 5, through which the needle 3 passes into the cavity of the reservoir 4, and means for fixing and fixing the position of the reservoir 4 in the housing 1, consisting of a groove 6 that is made in the housing 1 and is fixed to the reservoir the pin 7, p memory location in the guide groove 6 of the body 1.
    The canal cavity in the needle 3 consists of a central blind channel 8, communicating with channel 2 of housing 1 and located perpendicularly to the blind channel 8 and connected with it a hole 9 with a diameter less than the thickness of the plug 5.
    The groove 6 is located radially around the needle point 3 and has two stepped sections 10 and 11 and a section 12 through which the finger 7 is inserted into the groove 6.
    Power ink head ink. This is done when the tank 4 is installed in the working position, in which the finger 7 is located in the area 11 of the groove 6, and the hole .9 of the needle 3 is located above the stopper 5, into the cutting
    In this case, the ink through the opening 9, the channel 8 of the needle 3 and the channel 2 of the housing 1 are fed to the working chambers of the writing head.
    Such installation of the tank 4 is achieved by its rotation around its axis, with the result that the finger 7 fixed on the tank 4, moving along the groove 6, will move the tank 4 in the vertical direction.
    When the tank is rotated in the opposite direction, the finger 7 will move from the lower portion 11 of the groove 6 to the upper portion 10, with the result that the reservoir will move upwards and the opening 9 of the needle 3 will be blocked by the stopper 5.
    A significant advantage of the proposed device is that both when opening and closing the inlet 9 of the needle 3 there is no change in the volume of the channels leading to the working chambers. Therefore, one should not be afraid of the release or suction of ink in the working chambers pi- ;; shuschy head.
    By. The perimeter of the tank 4 is provided with a contact device (not shown), controlled by a protrusion (not shown) on the tank 4. Using this contact device 4, the working chambers are controlled.
    The proposed device, due to its instructive features, makes it possible to increase the reliability of the printing device of the device for recording information with ink, which has been shown above.
