Description

 The device relates to the field of electromechanical information display devices and allows you to develop a solid field scoreboard.

A known information device containing a chassis, a coil with information plates and an engine [1]
A disadvantage of the known device is the significant weight and volume attributed to the area of information display.

The closest in technical essence to the claimed device is a device containing a propulsion device, a chassis with axles on which the first and second coils are freely mounted with a common tape formed from the observation side [2]
The disadvantage of this device is the significant amount and weight attributed to the display area of information recorded on the tape.

 The aim of the invention is to reduce the volume and weight of the device relative to the display area of information recorded on the tape, by increasing the compactness of the device.

 This goal is achieved by the fact that in the device containing the mover, the chassis with axles on which the first and second coils are freely mounted with a common tape formed from the observation side, each coil has one brush made of ferromagnetic material, the first and second electromagnets are introduced, and elastic elements, which together with the cheeks of the coils form a mover, the chassis of the device in the section is L-shaped, the axis of the coils are fixed on its side, on the base of the chassis opposite the cheek of each coil the first and second electromagnets are fixed, the first electromagnet is fixed using an elastic element movably in the plane of the chassis base, and the second electromagnet is fixed on it motionless, while the external U-shaped magnetic circuit of the first electromagnet is orthogonal to the cheek of the coil and the magnetic circuit of the second electromagnet and forms a working gap with it .

 In FIG. 1 shows a design of an information device; in FIG. 2 shows the design of the propulsion device.

 The information device (Fig. 1) contains a propulsion device 1, a chassis 2 with axles 3, on which the first 4 and second 5 coils are freely mounted with a common tape 6 formed on the observation side, each coil 4, 5 has one cheek 7 made of ferromagnetic of material, the first 8 and second 9 electromagnets and elastic elements 10 are introduced, which together with the cheeks 7 of the coils form a mover 1, the chassis 2 of the device in the section is L-shaped, the axis 3 of the coils 4, 5 are fixed on its side 11 Based on 12 chassis 2 opposite the cheek 7 each th coils 4,5 sequentially along the winding of the tape 6 secured the first and second 9 electromagnets. The first electromagnet 8 (FIG. 2) is fixed using an elastic element 10, for example, a spring, movably in the plane of the chassis base 12, and the second electromagnet 9 is fixed thereon, while the external U-shaped magnetic circuit 13 of the first electromagnet 8 is orthogonal to the coil cheek 7 and the magnetic circuit 14 of the second electromagnet 9 and forms with it a working gap z.

 The tape 6 with the information applied to it from the observation side can be formed, for example, by rollers 15 mounted on the chassis 2 (Fig. 1).

 The information device operates as follows.

 In the initial state, the tape 6 is completely wound, for example, on the second 5 reel, while in the field of observation (the plane between the rollers 15) on the tape 6 information is set. No current is supplied to the electromagnets 8.9 and there is a working gap z between the magnetic circuits of the first 8 and second 9 electromagnets (Fig. 2). To replace the information included part of the propulsion device 1, located opposite the ferromagnetic cheek 7 of the first coil 4 (figure 1). The electromagnets 8, 9 constituting the mover 1 are supplied with current pulses from the current drivers, which are controlled by a logic device (not shown in Fig.). Under the influence of a current pulse, the first 8 electromagnet (figure 2), freely fixed in the plane of the base 12 of the chassis, for example, on a spring 10 is attracted to the ferromagnetic cheek 7 and engages with it. After coupling the first electromagnet 8 with the cheek 7, the second electromagnet 9 is switched on, fixedly mounted on the base 12, which attracts the magnetic circuit 13 of the first electromagnet 8. Since the magnetic circuit 13 of the first electromagnet 8 is coupled to the ferromagnetic cheek 7 during the action of the current pulse on the second electromagnet 9 coil 4, then the tape 6, wound on it, moves by a certain amount, determined by the size of the gap z between the U-shaped magnetic circuit 13 of the first electromagnet 8 and the magnetic circuit 14 of the second electron nit 9. Then, the first 8 and second 9 electromagnets are switched off, the magnetic core 13 of the electromagnet 8 is disengaged from the ferromagnetic cheeks 7 of the coil 4 and the second magnetic core 14 of electromagnet 9 and under the action of the elastic member 10 returns to its original position. After that, the electromagnets again, in the above order, are supplied with current pulses. The process of adhesion and movement is repeated and the tape again moves by the same amount as in the previous cycle of the action of current pulses on the electromagnets 8, 9. The supply of current pulses on the electromagnets 8, 9 continues until the tape in the observation plane between the rollers 15 the necessary information does not appear.

 To rewind the tape in the opposite direction, the first 8 and second 9 electromagnets are included, located opposite the ferromagnetic cheek 7 of the second coil 5.

 The proposed technical solution, due to the simplification of the propulsion device (by combining the rotor function with the cheek of the coil and the direct use of electromagnets) and arranging it between the base of the L-shaped chassis and the tape wound around the coil, allows developing compact, highly reliable and easy-to-use information devices that may be the main high-information board of a continuous field.

 According to the proposed technical solution, a mock-up of an information device was made, which showed operability. Moreover, the ratio of the volume occupied by the device to the display area of information recorded on the tape exceeded the prototype by more than two times.
