Abstract
The utility model relates to a magnetic tape cassette, comprising a loosening limiter for preventing magnetic tapes loosening. The loosening limiter is integrated with the side of a baffle plate which extends upward from the bottom of the outer shell of the magnetic tape cassette, and the loosening limiter is provided with a flexible thin rectangular plate. The loosening limiter comprises a most near part integrated with the side of the baffle plate, a free end part which extends from the most near part, a low friction material coating added on the free end part, and an outer opening arranged on the middle of the upper part of the loosening limiter. In addition, the thickness of the loosening limiter is gradually decreased from the most near part to the free end part so as to provide sufficient compliance and elasticity.
Description
The present invention relates to a kind of tape cassete, particularly a kind of tape cassete that has with the lax limiter of tape cassete housing global formation, it is used to prevent or reduces the lax or looseness (moving) of the tape on the rotatable reel in the tape cassete housing.
Usually, a kind of video tape recording/or replay device that is used for, the tape cassete that is called " VCR " comprises that has the tape cassete housing that upper and lower two parts fit together, and comprises two rotatable reels and the one section tape on the reel in the tape cassete housing.
For this tape cassete, when it just is transmitted or when it engages with VCR or throws off, the phenomenon that the lax of tape just may be taken place or unclamp.Especially, if two reels are driven in the VCR operating process asynchronously, then tape will produce laxly, thisly lax can damage tape or cause record or replay operations to be out of order.
Therefore, the various lax limiter that is used to limit or tighten tape has been disclosed by prior art.For example: at United States Patent (USP) 3,797, a kind of lax limiter that is provided in No. 779 comprises a soft band of elasticity, and its end is fixed on the tape cassete housing, also has a free end with one deck low-friction material coated.The free end that is somebody's turn to do lax limiter is pressed against the fixed part of tape cassete housing with tape, so just prevented that tape is lax in the tape cassete housing.
In addition, United States Patent (USP) 4,290,567,4,518,135,4,569,492,4,598,329,4,606,513,4,773,615 and 4,819,890 have disclosed some kinds of lax limiters, and attempt prevents tape looseing.
Though the lax limiter of those that disclose in above-mentioned prior art has been used for its intended purposes.But the common defects that exists in the design of this prior art is, needs an additional stationary installation, and for example viscose glue or the mechanical fasteners limiter that will relax is connected to the tape cassete housing.Therefore, because the connector of lax limiter has increased extra manufacturing step, the cost of making tape cassete is improved.In addition because the structure of these lax limiters is quite meticulous, and their fastening operation is very inconvenient usually, and their are not only expensive so make, and non-normalizing is time-consuming.Therefore, after long-term the use, the lax limiter of these prior arts just breaks away from or separates with tape cassete.
The purpose of this invention is to provide a kind of improved tape cassete, this tape cassete has a kind of lax limiter, when tape cassete just is transmitted or when engaging or unloading, can prevent or reduce the tape on the reel and the tape that extends from reel lax and loosening from VCR.
Another object of the present invention provides a kind of tape cassete with lax limiter, and this limiter can make tape tape channel along appointment in tape cassete stably move.
A further object of the invention provides a kind of above-mentioned lax limiter shortcoming of overcoming, and becomes easily the tape cassete of the lax limiter that unloads from tape cassete.
Further purpose of the present invention provides a kind of tape cassete with a lax limiter, and this tape cassete can be with the production of quite low cost-effective rate.
Above-mentioned purpose of the present invention is finished by a kind of tape cassete is provided.This tape cassete comprises a lax limiter with tape cassete housing global formation, and the place has opening outside in the middle of lax limiter top.
Above-mentioned purpose of the present invention and advantage can be found out from the description below in conjunction with accompanying drawing significantly, wherein, in different figure, refer to identical parts with same numeral.
Fig. 1 is the sectional plan view of an expression according to the tape cassete of the lax limiter of the novelty of of the present invention and tape cassete housing global formation.
Fig. 2 is the enlarged perspective of the lax limiter of tape cassete shown in Figure 1.
With reference to Fig. 1, comprise one by going to the bottom 12 and the tape cassete shell formed of loam cake 14 according to the tape cassete 10 of a most preferred embodiment of the present invention.Two are contained in 16,18 and one sections of the rotatable reels of going to the bottom on 12 tape 20 on the reel 16,18.Going to the bottom 12 comprises one first and second cylinder guide finger 22,24, and they all are fixed in the tape channel, its objective is make tape 20 in tape cassete by desired direction operation.In addition, go to the bottom 12 have one from the bottom surface upwardly extending the molded diaphragm 26 and tape channel of a tape 20 that moves along dividing plate 26 outsides is arranged.
Be clear that more that in Fig. 2 in most preferred embodiment of the present invention, lax limiter or elastic baffle 28(for the sake of clarity remove tape), at the side global formation of neighbouring part 30 with dividing plate 26, and be positioned at guide finger 22,24 near.Specifically, the lax limiter 28 of mold pressing has suitable flexibility and elasticity, and consequently pressing tape 20 leans against first guide finger 22 that is positioned at one of reel 18, and when tape 20 is mobile in tape cassete 10, can keep the stability of tape operation.Preferably baffle plate 28 is by suitable flexible plastics, for example HIPS(high impact polystyrene), impact strength polystyrene among the MIPS(), ABS resin or POM(polyoxymethylene) thin rectangular plate constitute.In addition, baffle plate 28 preferred design become with first guide finger 22 enough close contact, departs from first guide finger 22 to prevent tape.
Explanation as Fig. 1 and Fig. 2, preferably lax limiter 28 can reduce thickness or gradient gradually, promptly the free end portion 32 from neighbouring part 30 to lax limiter 28 reduces gradually, for it provides a desired elasticity, neighbouring part 30 preferred thickness range of lax limiter 28 be 0.5mm to 1.5mm, the thickness preferable range of the free end portion 32 of lax limiter 28 is that 0.2mm is to 0.5mm.Baffle plate is that the level and smooth contact of the free end portion 32 of limiter 28 presses against first guide finger 22 with tape 20, and by its given elasticity to prevent tape looseing.
As shown in Figure 2, the place provides one to be square or the outer opening 34 of rectangle usually in the middle of the top of lax limiter 28.Opening 34 is used for reducing the cross-sectional area of lax limiter 28 center sections, so that provide desired elastic force for lax limiter 28.And opening 34 allows to arrive optical pickup apparatus from the light beam of light emitting devices, when tape 20 plays sensitive detection effect during almost or fully not around one of reel, to produce for example recoil of tape.In addition because the existence of opening 34, can boost productivity, such as, module just is easy to throw off from its mould.
As shown in Figure 2, the free end portion 32 of lax limiter 28 can coated one deck than low-friction material, teflon for example.The coating 36 of this low-friction material is provided on one of free end portion 32 of lax limiter 28 or two sides; with tape 20 contacts; and tape is pressed against first guide finger 22, the coating 36 of lax limiter 28 be used to protect tape to make and be not subjected to excessive wear or since the damage that tape 20 and lax limiter 28 Continuous Contact cause encircle.
Though the present invention represents for preferred embodiment and has narrated.But the ripe refining technician of this area will recognize: certain changes and improvements of being carried out all do not break away from the present invention, in the spirit and scope that following claim limited.
