Abstract
Disclosed is a tape running mechanism relative to the recorder base. The utility model mainly comprises a casing which a shaft hole of a driving shaft is arranged on, a tape sending disc, a tape collecting disc, a guide wheel, a tension wheel, an elastic membrane belt, a circulation driving belt and a magnetic-tape which are all arranged in the casing. The utility model can also have a reverse drive device in order that the tape running mechanism can be used matching the existing machine base. The magnetic-tape is scarcely under stress because the utility model drives the magnetic-tape to run via the friction force generated by the circulation driving belt; therefore, the aims achieved of the utility model are to eliminate the fault fundamentally in the process of running of the magnetic-tape and apply to the thin magnetic-tape of high capacity.
Description
The utility model relates to a kind of tape travelling mechanism with respect to support, the particularly a kind of tape travelling mechanism with respect to support that can fundamentally eliminate the mechanical drive fault in the tape operational process.
Existing tape travelling mechanism with respect to support is in the tape operational process, because the influence of the factors such as dynamic change of rotating torque and magnetic tape tension, be difficult to satisfy the harsh requirement of mechanical coupling aspect always, perhaps can not guarantee to reach this requirement for a long time in actual use.For the many faults that come from mechanical property that may imply, the mechanical drive fault of slim magnetic recording tape in audio video reproduction process particularly, users can only be by choosing high-quality product and maintaining it meticulously and avoid.Described mechanical drive fault is because the coupling of driving torque is malfunctioning or the physical strength deficiency of tape own is caused as excessive band of strand band or stretching belt phenomenon occur in the tape operational process.In order to address the above problem, people also once proposed some improvement projects, but all failed fundamentally to eliminate the mechanical drive fault in the tape operational process.
The purpose of this utility model is to provide a kind of tape travelling mechanism with respect to support that can fundamentally eliminate the mechanical drive fault in the tape operational process.
The purpose of this utility model also is to provide a kind of tape travelling mechanism with respect to support that is suitable for the high power capacity thin tape.
The utility model is achieved in that
A kind of tape travelling mechanism with respect to support, comprise: housing, main drive shaft axis hole on the housing, centre separated by a distance, middle part is the belt-sending disk and the machine reel of band tooth circular hole in the housing, the angle sheave at housing internal upper part drift angle place, the stretching pulley at lower middle position place in the housing, around the elastic membrane band between angle sheave and the stretching pulley, the perseverance of being close to it in the elastic membrane band outside is long non-extensible and have a circulation rotating band of rubbing surface, and the tape of everywhere being close to the circulation rotating band on running way in the circulation rotating band outside, the tape magnetic surface is wound on above-mentioned belt-sending disk and the machine reel inwards.
A kind of tape travelling mechanism with respect to support, comprise: housing, main drive shaft axis hole on the housing, centre separated by a distance, middle part is the belt-sending disk and the machine reel of circular hole in the housing, the angle sheave at housing internal upper part drift angle place, the stretching pulley at lower middle position place in the housing, around the elastic membrane band between angle sheave and the stretching pulley, the perseverance of being close to it in the elastic membrane band outside is long non-extensible and have a circulation rotating band of rubbing surface, and the tape of everywhere being close to the circulation rotating band on running way in the circulation rotating band outside, the tape magnetic surface is wound on above-mentioned sending inwards, on the machine reel, further, in the middle circular hole of this above-mentioned belt-sending disk and machine reel, can be inserted with reverse transmission.
The utility model is to carry out improved a kind of tape travelling mechanism with respect to support on the basis of existing technology, the tape on running way in rotating band and its outside of wherein circulating is close to everywhere, drive the tape operation by friction force, make tape guided by it, itself is stressed hardly, fundamentally eliminated at the tape operational process because the coupling of rotating torque is malfunctioning or the not enough caused mechanical rotation fault of the physical strength of tape own, this advantage embodies more obviously when the F.F. of tape is fallen soon.Further, the serious machine error of existing magnetic tape deck or the tape that fault is caused in tape operational process damage are owing to having avoided with respect to the shutting down at most of tough and tensile circulation rotating band in the tape travelling mechanism of support.The utility model can satisfy and makes tape very thin and requirement that improve capacity also promptly provides a kind of desirable tape travelling mechanism with respect to support that is applicable to the high power capacity thin tape.By setting up reverse transmission, the utility model can also be used with existing support.In addition by using the elastic membrane band that tape can be pressed to magnetic head can save felt and elastic pressuring plate; The circulation rotating band also can have conductive characteristic, reduces the antistatic requirement to tape greatly; The tape magnetic surface is reeled inwards and can be reduced print-through.
