Abstract
To obtain an epoxy resin composition outstanding in mechanical strength and resistance to deteriorating matters such as SF6, for use in heavy electrical parts such as air break switch with high resistance to voltage as a requirement, by incorporating an epoxy resin composition with an alumina compound. The objective composition can be obtained by incorporating (A) an epoxy resin composition (pref. comprising 15-40pts.wt. of an epoxy resin such as phenol novolak-type epoxy resin, 1-20pts.wt. of curing agent plus curing accelerator and 1-10pts.wt. of releasant, etc.) with (B) an alumina compound (pref., alumina or aluminum hydroxide).
Description
The present invention relates to the keeping device for magnetic tape cassette of cassette tape recorder, be specifically related to tape cassete and still be unkitted the fashionable constant keeping device for magnetic tape cassette of apical position that can use with the spring members that tape cassete is drawn close to magnetic head.
As everyone knows, in cassette tape recorder, when being arranged on tape cassete on the blattnerphone support when tape cassete is packed into and packing the position into, need tape cassete is fixedly secured on support.If fix not firmly, then when tape running, the relevant position of magnetic head and tape will change, thereby can not give play to desirable performance.
Thereby, existing cassette tape recorder all resembles Fig. 3 the position of packing into of the tape cassete on support and is provided with pillar 2,3, be provided with leaf spring 5 with the height and position And of this pillar 2,3 restriction tape cassetes 4 at pack into the rear of position of tape cassete, the top of backup plate spring 5 pushes tape cassete 4 to the magnetic head direction.The lower end of leaf spring 5 is screwed at pack into the rear position Shang ， And at position of tape cassete and becomes "＜" font by fixed part to a lateral bending of pillar 2, and the top ， And that a side on its top extends to pillar 2 makes its upper end form circular arc portion 6.Like this, when tape cassete 4 being placed on the pillar 2,3, just make the upper back of tape cassete 4 and the bottom crimping of circular arc portion 6.Because the bending force of this moment has sent tape cassete 4 top to the magnetic head direction with push up power to support 1 direction, thereby tape cassete 4 firmly is fixed on the pillar 2,3, promptly has been fixed on the support.Among Fig. 37 is reel shafts.
There are the following problems to press the existing keeping device for magnetic tape cassette that said structure constitutes, that is by being directly proportional with the initial bending amount of leaf spring 5 to the pushing force of magnetic head direction with to the pushing intensity of force of support direction that leaf spring 5 produces.Thereby the amount of bow situation of double dot dash line B more can fixedly secure tape cassete 4 than the amount of bow situation of double dot dash line A among Fig. 4., if by setting the initial bending amount shown in the B like that, then be unkitted fashionablely at tape cassete, the top of leaf spring 5 will be positioned at the place ahead far away, top of pillar.This is just along the direction of packing into (that is the direction shown in Fig. 4 double dot dash line) of tape cassete when packing tape cassete 4 into, just can produce leaf spring 5 distortion or turnover causes obstacle to tape cassete problem.In order to address the above problem, the thickness that can increase leaf spring 5 to be strengthening the ability of its recovery, and can reduce the initial bending amount thus., so, can produce again increases the problem of making leaf spring 5 required expenses.
In sum, existing keeping device for magnetic tape cassette is under the prerequisite that does not increase spring members thickness, and as fixedly securing tape cassete on support, spring members is out of shape or causes the problem of obstacle to the turnover of tape cassete in the time of will being created in the tape cassete turnover.
The purpose of this invention is to provide a kind of keeping device for magnetic tape cassette, its structure not only simply but also not increases spring members thickness, and can prevent the above-described problem from occurring.
The measure that the present invention addresses the above problem is that spring members is crimped on the pillar.
If the middle part of spring members is crimped on the pillar, then by such crimping, can make the pressure independent of spring members and spring, and its apical position must be limited on the constant position, therefore can not increase spring members thickness, and the top that makes spring members is positioned on the position that does not hinder tape cassete turnover, thereby strengthens the pressure of spring members, and strengthens the pushing force of tape cassete that is hold power.
Referring now to the following drawings explanation embodiment.
Fig. 1 is the oblique view of the only expression keeping device for magnetic tape cassette major part relevant with one embodiment of the invention;
Fig. 2 is the partial side view of this holding device when packing tape cassete into;
Fig. 3 is the side view of the holding device of prior art;
Fig. 4 is the synoptic diagram of explanation existing apparatus problem.
In Fig. 1 and Fig. 2, the symbol that uses with the same section of Fig. 3 and Fig. 4 is also identical.
In the related keeping device for magnetic tape cassette of present embodiment, give tape cassete 4 is crimped on rearward end from pillar 2 to the middle part of the leaf spring 5 of the power of magnetic head direction and support 1 direction, that is the becoming one with it to rearward projection 11 of the rearward end of pillar 2, the middle part of spring members 5 is crimped on this projection 11.
If such structure is unkitted fashionablely at tape cassete 4, leaf spring 5 is subjected to being located at the restriction of the projection 11 on the pillar 2 towards the recovery angle of rotation of pillar 2 directions.Thereby being unkitted fashionablely at tape cassete 4, the apical position of leaf spring 5 must remain on the constant position.So, as long as preestablish the height of projection 11, so that tape cassete 4 is unkitted the apical position of fashionable leaf spring 5 when being in the position that does not hinder tape cassete 4 turnover, can strengthen the initial bending amount of leaf spring 5, strengthen its restorability, also can strengthen pushing force, also do not hinder the turnover And of tape cassete 4 and when tape cassete 4 was packed into, leaf spring 5 can not be out of shape yet tape cassete 4.In other words,, need not to increase the thickness of leaf spring 5 if adopt said structure, do not hinder the turnover ， And of tape cassete 3 yet and when tape cassete 4 is packed into leaf spring 5 indeformable, thereby give full play to the firm function of blocking tape cassete.
The present invention is not limited to the situation of the foregoing description, uses leaf spring as spring members in the above-described embodiments, uses cylindrical spring also to be fine certainly.
Generally speaking, adopt the present invention can not increase spring members structure thickness or diameter, this spring members does not hinder tape cassete turnover ， And and when tape cassete was packed into, spring members was indeformable, thereby has given full play to the firm function of blocking tape cassete.
