The invention relates to computing, in particular to electromechanical printing devices, for outputting information from electronically-driven machines. A literary carrier for a selective printing device containing a drive endless belt with lettered links, each of which is made of a carcass mounted on a belt perpendicular to the print line and a letter strengthened on its working side, and means 1d for fixing literal events located with the known The inner side of the belt and including magnetic elements C However, this device is characterized by insufficient print quality, due to the fact that the presence of friction Between an infinite belt with lettered links and a support element located in the printing zone, leads to geasis wear of the contacting parts, filling the gaps with wear products. The aim of the invention is to improve the print quality. This goal is achieved by the fact that in a letter carrier a device for selective printing, containing a drive endless belt located along the Printing Line, with lettered links, each of which is made of a frame mounted on the belt perpendicular to the print line and attached to its working side, and means for fixing the lettering units located on the inner side of the belt and including magnetic elements, the means for fixing has a support, a spanning support outside the printing zone with a clearance guide rolling elements located in the gap between the support and the guide wall facing the belt are U-shaped, with the crossbar of this wall parallel to the plane of the belt, the grooves are parallel to the ends of the wall posts, the endless belt is located between the wall uprights, and the magnetic elements are located on the inner side of the dp fixation means of the lettered links, while the frame of each lettered link is made of magnetic material and has grooves corresponding to the grooves of the wall pillars and facing them d arranging rolling elements. In addition, the grooves of the pillars of the support wall and the frameworks of the lettered links are V-shaped. FIG. 1 shows a letter carrier of a device for selective printing with local sections, a general view; in fig. 2 is a section A-A in FIG. 1 (variant of the relative position of the letter unit and the guide): in FIG. 3 is a section BB in FIG. 1 (clip). The letter carrier of the device for selective printing contains a drive endless ramen 1 located along the print line with letter links 2. Each of the letter links is made of a frame 3 mounted on the belt 1 perpendicular to the print line of the frame 3 and the letter 4 fixed on its working side. is located on the inner side of the belt and includes magnetic elements 5. A means of fixing the lettered links also has a support 6, covering the support outside the printing zone with a gap, a guide 7 and quality elements 8, which are located in the gap between the support 6 and the guide 7. The support wall 9 facing the belt 1 is U-shaped. The crossbar 10 of this wall is parallel to the plane of the belt 1. At the ends of the uprights 11 of the wall 9, parallel printing lines of the grooves 12 are made. The belt 1 is located between the uprights 11 of the wall 9, and the magnetic elements are located on the inside of the means for fixing lettered links. The frame 3 of each literal link is made of magnetic material and has grooves 13, corresponding to the grooves 12 of the uprights of the wall and facing them to accommodate rolling elements 8. The grooves 12 and 13 are V-shaped. The belt 1 is made of elastic material and reinforced with steel tape. The teeth located on the inner side of the belt provide the possibility of its engagement with the driving gear wheel 14. With the help of the wheel 15, due to its movement in the direction of movement of the lettered links 2 on the straight line 31, the required tension of the endless belt 1 with lettered links 2 is ensured. 4, printing hammers 16 are positioned along the printing line to transfer information to a paper tape through the dye tape. The frame 3 of the lettered link 2, the rolling elements 8, the support 6, and also the guide 7 are made of metal. The carrier works as follows. The drive gear 14 engages with the teeth of the belt 1, in connection with which the endless belt 1 with the lettered links 2 is set in motion. The rolling elements in the print zone in two rows roll the surfaces of the 12 and 13 and , moving in the direction of movement of the belt 1 with the lettering units 2, push each other, fall into the guide 7. From the guide elements fall into the print zone 0 At certain times, the printing hammers 16 strike the desired letter 4 through paper and ink ribbons, thereby nose information, for example, of a computer on a paper tape. When the movement of lettered links 2. in the print zone, each literal link through each of the recesses is in contact with at least two rolling elements 8. This, as well as the presence of two parallel grooves in each lettered link 2 (and accordingly in support 6) ensures stable operation of the links in the printing process. The use of the invention will improve the reliability of the device for selective printing, print quality. Improving the reliability of the device and quality is achieved by completely eliminating sliding friction between the links and the yoke (only rolling friction is present).
