![]() Tape transport mechanism of cassette tape recorder
专利摘要:
A magnetic-tape deck for magnetic-tape cassettes (1) comprises a playing-loop device with playing-loop guides (8) which withdraw the magnetic tape (2) from the cassette to form a playing loop, and fast-winding means which, for facilitating fast winding between the two reels (3) of the cassette, only slightly withdraw the magnetic tape from the cassette so as to form a fast-winding loop such that the front of the magnetic tape is in contact with at least one draining element for draining static electricity from the front of the magnetic tape. The draining element (16) is arranged on a movable playing-loop-guide support (10) in a position substantially opposite the playing-loop guide (8) and on the opposite side of the magnetic tape. 公开号:SU1338788A3 申请号:SU833573798 申请日:1983-04-11 公开日:1987-09-15 发明作者:Корнелиус Йоханнес;Мюллер Антониус 申请人:Н.В.Филипс Глоэлампенфабрикен (Фирма); IPC主号:
专利说明:
The invention relates to the accumulation of information, in particular to tape-drive mechanisms of tape recorders. The purpose of the invention is to simplify the design of the tape mechanism and increase its compactness. Figure 1 shows a tape mechanism of a tape recorder prior to refueling a magnetic tape; 2 is the same, B playback mode; figure 3 - the same, in the mode of fast forward. The tape mechanism comprises guiding elements 1 and 2, made in the form of cylindrical guiding elements and mounted on the first 3 and second 4 rotary elements with the possibility of pulling the magnetic tape 5 wound on the coils 6 and 7 from the cassette 8 and filling it with the guide drum 9 when rotating the first 3 and second 4 pivoting elements from the first extreme position to the second extreme position in the playback mode. At the same time, at least one rotary magnetic head 10 is located inside the guide drum 9, and the first and second 4 rotary elements are made in the form of arcuate rotary levers kinematically connected to one another and the other by means of a pin 11 located in their arcuate grooves 12 and 13. The pin 11 is mounted on one shoulder of the two shoulders lever 14, the other shoulder of which is made with a pin 15 located in the profiled guide groove 16 of the worm wheel 17, connected via a worm to 18 with an electric motor nineteen. The tape drive mechanism also contains the first 20 and second 21 additional guide elements made in the form of cylindrical on the guide rollers and mounted respectively on the third 22 and fourth 23 rotary elements with the possibility of pulling the magnetic tape 5 out of the cassette 8 when turning the third 22 and fourth 23 rotary elements from the first extreme position to the second extreme position in, the mode of fast-forwarding. The third 22 and fourth 23 rotatable elements are made in the form of rotary levers connected kinematically five five 0 five 0 five 0 five TU 24 with a pin 25 mounted in another profiled guide groove 26 of the worm gear 17. The first 3, second 4, third 22 and fourth 23 rotatable elements are placed on board 27, on which fixed magnetic heads 28 are mounted. In addition, guide drum 8 and electric motor 19 are also strengthened on board 27. The tape mechanism contains the first 29 and second 30 current collectors, made in the form of cylindrical metal struts. The first current collector 29 is mounted on the first pivot member 3 so that it can mate with the working layer of the magnetic tape 5 in the fast forward mode at the average position of the first pivot member 3 between its extreme positions. First current collector 29 is mounted to form an air gap between it and the working layer of the magnetic tape 5 in the playback mode. The second current collector 30 is mounted on the second rotary element 4 with the possibility of interface with the working layer of the magnetic tape 5 in the mode of fast-forwarding with the average position of the second rotary element 4 between its extreme positions. Second current collector 30 mounted to form an air gap between it and the working layer of magnetic tape 5 in playback mode. In the tape machine, the first additional guide member 20 is made in the form of a pressure roller, which is installed with the possibility of pressing the magnetic tape 5 to the drive shaft 31. Tape mechanism of the cassette tape recorder works as follows, In the playback mode, after the cassette 8 is installed on the board 27, the electric motor 19 through the worm gear 17 acts on the double-arm lever 14 and on the first 24, which rotate the first 3, second 4, third 22 and fourth 23 turning elements. The latter leads to the fact that the first 1 and second 2 guide elements and the first 20 and second 21 additional guide elements one The magnetic tape 5 is pulled out of the cassette 8. At the same time, the first 1 and second 2 guide elements load the magnetic tape 5 onto the guide drum 9, and the first additional guide element 20 presses it against the drive shaft 31. During playback, the drive shaft 31 provides movement of the magnetic tape along the helix relative to the guide drum 9, winding it from the coil 6 and winding onto the coil 7. In this case, the rotating magnetic heads 10 alternately move along the magnetic tape 8 due to their rotation. In the accelerated transfer mode, the first 20 and second 21 additional guide elements pull the magnetic tape 5 out of the cassette 8 and press it to the first 29 and second 30 current collectors with its working layer. At the same time, the first 1 and second 2 guide elements do not charge the magnetic tape 5 onto the guide drum 9, and the first additional guide element 20 does not press it against the drive shaft 31. In the process of accelerated rewinding, the electrostatic charge formed on the working layer tape 5 due to friction, is removed by the first 29 and second 30 current collectors.
