    A retractable mechanical pencil unit 3 and a ball point or rollerball pen unit 3' are assembled in a lower barrel 1 of a writing instrument having an upper barrel 2 which is rotatable in one or two directions relative to the lower barrel and guide 9 around its axis. Cam 8 within said upper barrel of the writing instrument engages with the pen and pencil units to selectively shift them axially into writing position. The upper barrel is shiftable axially relative to said lower barrel by a distance set by rotating sector 12 and stationary cam 12 on the head 16 of guide 9 to operate the lead feed of the mechanical pencil unit when this unit is in its writing position, but the set distance reduces to zero and the upper barrel is axially non-shiftable relative to the lower barrel when the pen unit is in its writing position. <IMAGE>

The second option.
    The combined writing device comprises a tubular body, made in two parts in height, consisting of the bottom part 1, connected to the top part 2 with a possibility of rotation by 180 relative to it and with the possibility of axial displacement.
    The lower part of the body is made with holes at the ends and has a cylindrical sleeve 3 with two diametrically located slots 4 and 5 and
    locking cam 6 on the upper end. In the upper part of the body there is a guide pull-out 7, covering the upper part of the cylindrical coupling and having in the upper part a segment stopper 8 that interacts with the cam 6. In the lower part of the body they are diametrically opposite to its axis and mounted with the possibility of axial
    the mechanical pencil 9 and the ball writing unit 10 move. The writing elements of the pencil and ball node face the opening of the lower part of the body,
    Mechanical pencil and ball writing unit have on the upper ends located in the grooves 4 and 5 of the cylindrical coupling 3 sliders 11 and 12, interacting with the sleeve 7. The mechanical pencil has a casing
    13 with an emphasis and with a conical tip 14. In the casing with a possibility of axial movement, a rod 15 connected to the slider 11 is installed,
    connected to the housing through the connecting sleeve 16, as well as to the collet chuck 17, which cooperates with the clip 18. At the handpiece, the sealing ring 19 is mounted,
    The combined writing device has a coupling 20 installed in the lower part of the body. The cylindrical coupling 3 has an annular protrusion 21 in the lower part, rigidly connected to the coupling coupling. The guide bushing 7 has a cam 22 and a groove 23, and the sliders of a mechanical pencil and ball writer node have protrusions 24 for engaging with the cam and the bushing groove. On the sleeve 7, a fixing ring 25 is installed. According to the first embodiment, the cam 22 of the guide sleeve is made in the form of two curviline protrusions 26 connected by ends, in the joint zone of which a groove 23 is located. The cylindrical sleeve 3 is connected with the direction of the sleeve 7 to rotate relative to the vertical axis in both directions. According to the second embodiment of the writing device, the guide sleeve 7 has an arcuate, horizontally disposed portion 27, and the cam is embodied as a vertical projection 28 bounded by a straight portion 29 and a curvilinear portion 30- connected in the lower part in the slot 23. . The cylindrical sleeve 3 is connected with the guide sleeve 7 so that it can be rotated relative to the vertical axis in one direction. The process of extending and moving the pencil and element of the ball of the writing unit into the writing or retracted position is shown in Figs. 13 and 14. FIG. 14 shows the position in which both writing elements are removed. In this position, the beveled surfaces of the protrusions protruding at the apex 24 at the ends of the rods guided in the grooves 4 and 5 of the cylindrical coupling 3 are respectively elastically pressed into the middle part of the sliding curvilinear protrusions 25 of the sleeve 7 by means of springs. At this moment, the segment stopper 8 in the upper part of the sleeve 7 abuts against the beveled surface of the cam 6. The dash-dotted line at the bottom of the writing elements indicates the position of the neck of the lower part of the body. In order to push the element of the ball-point knot into the writing position, the upper part of the body, namely the sleeve 7 attached to it, is turned to the position shown in Fig. 13. As a result of this rotation, the beveled surface of the pencil-shaped protrusion 24 at the apex 24 slides up along the beveled surface of cam 22 and stops on a flat portion. 04 Sharpened. At the apex, the protrusion 24 of the ball assembly slides down along the beveled surface of the sleeve 7 and enters the engagement with the groove 23 at the apex of the said sliding beveled surfaces. At this moment, the segment stopper 8 of the sleeve 7 slides into the gap t formed between the lower flat surface of the cam 6 and the upper surface of the coupling 3. As a result, the sleeve 7 is displaced slightly below the position shown in Fig. 11. The gap t is of such magnitude that the sleeve 7 becomes non-displaceable in the axial direction relative to the coupling 9 when the stopper 8 enters the specified gap. In this position (Fig. 14), the element of the ball assembly is brought to the writing position when the sleeve 7 with the upper part 2 of the body attached to it is engaged without displacement in the axial direction. For the purpose of moving the upper part 2 of the housing, namely the sleeve 7, to the position shown in FIG. 15 (180 from the position shown in FIG. 14), to the writing position of the mechanical pencil element. As a result of this rotation, the beveled surface of the pointed at the top of the protrusion 24 of the mechanical pencil slides down the beveled surface of the sleeve 7 until it engages with the groove 23 at the apex of the sliding beveled surfaces. Thus, the pencil element is in the writing position. The segment stopper 8 slides upwards along the inclined surface of the cam 6 and disengages from the cam 6, while at the same time it rests against the lower end of the fixing ring 25 attached to the sleeve 7, as shown in Fig. 3, thus preventing movement upwards cylindrical coupling 3 from the spring. Due to the fact that the stopper 8 is brought into this position, the sleeve 7 moves upward relative to the coupling 3 in accordance with the displacement of the segment stopper 8. As indicated, in the position shown in Fig. 15, the stopper 8 is in the position in which He does not interact with Cam 6 with TJPa 26 and rests against the locking ring 25 under the action of springs, while, as a result, the sleeve 7 is pressed downwards, i.e. The upper part 2 of the housing in the axial direction, it can be freely shifted to the position shown in FIG. As a result of the displacement of the sleeve 7 in the axial direction, the mechanical pencil 9 is displaced in the same direction. The distance between the lower end of the segment stopper 8 and the upper side of the coupling 3, namely the displacement distance in the axial direction of the stopper in the position shown in Fig. 15, is selected such that the magnitude of the displacement of the pencil 9 at the axial displacement of the sleeve 7 allows the lead to be released as a result of the interaction of the abutment of the pencil casing 13 into the neck of the lower part 1 of the housing. Thus, the sleeve 7 ,. those. the body part 2 attached to it is pushed out in the axial direction and retracted, resulting in a smooth and reliable release of the pencil lead, ensuring the writing position. When the pencil is in the writing position (FIG. 15) and the lower part of the body is fixed, the upper part 2, i.e. sleeve 7 is displaced. The pencil 9 is displaced further downwards (Fig. 16) in such a way that the abutment of the casing 13 of the pencil 9 abuts against the neck of the lower part 1 of the housing. Upon further pressing and displacing the sleeve 7 down, the connecting sleeve 16 connected to the shaft 15 slides toward the end of the mechanical pencil relative to the case 13, As the case is resting against the case rests on the body neck. In accordance with the movement of the connecting sleeve 16, the collet chuck 17 is displaced to the end of the pencil. As a result, the lead, held by the engagement of the collet with the clip 18, is fed to the end of the caravan dash. together with the cartridge rests in the stopping step of the tip 1A and its further movement stops, as a result of which the cartridge 17 is separated from the clamp 18 and the stylus is released from the clamp in the cartridge 17. Thus, the stylus is released at a distance This is determined by the amount of displacement of the clamp 18. Further, when the load on the sleeve 7 is removed, i.e. the pressure on the upper part 2 of the housing, in the state where the lead is held by the elastic support ring 19, the cartridge 17, the coupling sleeve 16 and the rod 15 are moved to the initial position, as a result of which the cartridge 17 will firmly hold the stylus again. By repeating the reciprocating displacement by pressing the upper part 2 of the body, the stylus can be extended from the tip 14 to the desired amount convenient for operation. The process of extending and retracting the lead of the mechanical pencil and the ball point element to the writing or retracted position according to the second variant is carried out as follows. In a position where both writing elements are removed (Fig. 17), the inclined surfaces of the apexes which are sharp at the apex and directed in the slots 4 and 5 of the cylindrical sleeve 3 are respectively elastically abutted against the middle part of the sliding curvilinear section 30 of the hub 7; At this moment, the stopper 8 located in the upper part of the sleeve 7 abuts against the straight line section 29 of the cam 6. The dash-dotted line shown below the writing elements indicates the position of the end neck of the lower part 1 of the housing. In order to move the pencil 9 to the writing position, turn the upper part 2 of the body, i.e. guide sleeve 7 to the position shown in Fig. 19. As a result of this rotation, the beveled surface of the pinned part of the pencil protrusion 24 sharpened at the top slides down the curvilinear section 30 to the top to engage with the groove 23 of the sleeve 7. At this time, the stopper 8 of the sleeve 7 slides along the inclined section of the cam 6 and is set to plot where there is no cam surface. As a result, the sleeve 7 rises in a direction from the position shown in Fig. 18 to the position shown in Fig. 19. 7 Thus, the apex, which is pointed at the apex, of the protrusion 24 of the element of the ball-type writing unit gradually departs from the section 27 of the sleeve 7 to achieve the position shown in Fig. 19. The upper end of the stopper 8 rests on the lower end of the fixing ring 25 under the influence of the spring, and between the upper end of the coupling 3 and the lower end of the stopper 8 there is a gap d (Fig. 19). This interval .d is chosen to correspond to the displacement (shock distance downward in the axial direction of the upper part 2 of the body, i.e. sleeve 7, after the lead is released. In the position shown in Fig. 19, the pencil is in the writing position The stopper 8 rests in the lower torus of the fixing ring 25 under the influence of a spring to maintain the gap d and by pressing on the upper part 2 of the housing, i.e. the sleeve 7 downwards in the axial direction, it can be unhindered in the position shown in FIG. .20. As a result of the displacement The tulk 7 pencil also shifts, the gap d is chosen so that the magnitude of the pencil displacement together with the displacement of the sleeve 7 in the axial direction provides release of the lead as a result of the interaction of the emphasis of the casing 13 into the neck of the lower part of the body 1. Thus, as a result of placing in the axial direction , releasing and reciprocating 008 the movement of the sleeve 7, i.e. the upper part of the body attached to it, the process of moving the pencil leads smoothly and reliably, ensuring the writing position. In order to extend the element of the ball writing unit 10 to the writing position, the sleeve 7 is rotated to the position shown in Fig. 17, and the pinned part 10 of the element of the ball unit 10 having the notch 23 at the top of the sleeve 28 is engaged. 7. In the position shown in Fig. 17, the stopper 8 enters the gap, t between the upper part of the coupling 3 and the lower flat surface of the cam 6. The magnitude of this gap t is chosen such that the sleeve becomes unbiased axially relative to the coupling 3 when the stopper zah Fits into the mentioned gap. According to the invention, the mechanical pencil and the ball point element can be smoothly and reliably withdrawn to the writing and locked position by rotating the upper part of the body in one or two directions, and the stylus can be extended by displacing the upper part 2 of the body in the axial direction, as a result, a combined writing instrument with a very simple design and reliability can be obtained.
