Extremely shown in Figure 5 as Fig. 3, the roof pressure portion 61 of nearby extending of the above-mentioned rewinding control lever 55 oriented follower gears 42 and the mate of driven wheel 27, shown in each figure of Fig. 6, the cardinal extremity of this roof pressure portion 61 is formed with the bendable portion 62 of a thin thickness, and this part can make roof pressure portion crooked about in the of 61.
Below roof pressure portion 61, be provided with protuberance 63 that extends forward and a pair of projection 64a that is positioned at its both sides, 64b.The projection 64a of one side leaves the mate of follower gear 42 and driven wheel 27, and is positioned between these two gears 42,27.As shown in Figure 6, projection 64a, the front and back of 64b is formed with the 1st and the 2nd dip plane 65a that extends and tilt to the rear of frame 1 along with to below separately, 65b.
Above-mentioned roof pressure portion 61 and projection 65a, 65b expose above frame 1 by the 3rd peristome 66 that is arranged on the frame 1, and the opening lateral margin about the 3rd peristome 66 is provided with inwardly outstanding guides 67a, 67b.These guidess 67a, 67b and above-mentioned roof pressure portion 61 constitute decontrols, and under follower gear 42 and state that driven wheel 27 is meshed, decontrol makes it to break away from and meshes along facewidth direction roof pressure follower gear 42, and the back will be described this.
Under the state of the not bulged-in Fig. 3 of rewinding control lever 55 and Fig. 6 (a), guides 67a, 67b are positioned at projection 64a, and the place ahead of 64b in the back of guides 67a, 67b, constitutes along with the 1st spigot surface 68a that extends upward and tilt to the front side of frame 1.And the guides 67a of a side is provided with downwards the extension 70 that prolongs, and the front of extension 70 constitutes with downward extension and the 2nd spigot surface 68b that tilts to the rear of frame 1.
Therefore, as shown in Figure 6, in case when pushing rewinding control lever 55, the 1st dip plane 65a of projection 64a, 64b just contacts with the 1st spigot surface 68a of guides 67a, 67b, and roof pressure portion 61 is bent upwards in bendable portion 62 parts, simultaneously projection 64a, 64b rides over guides 67a, on the 67b.
When projection 64a, 64b slipped over guides 67a, 67b, shown in Fig. 6 (c), the elastic restoring force of bendable portion 62 rotated top pressing device 61, projection 64a, 64b are located in guides 67a, the place ahead of 67b, and lockplate 58 is locked in this position to rewinding control lever 55.
On the other hand, as shown in Figure 4, the pushing of rewinding control lever 55 makes the engagement projections 50 of bend 56 pushing support members 47, makes follower gear 42 move to the position that is meshed with driven wheel 27, and at this moment, engagement projections 50 is divided a word with a hyphen at the end of a line from bend 56 in the recess 57.
In case push locking lever 59, rewinding control lever 55 resets to initial position, along with resetting of rewinding control lever, shown in Fig. 6 (c), the front that the 2nd dip plane 65b of projection 64a, 64b meets guides 67a, 67b, then shown in Fig. 6 (d), roof pressure portion 61 is in the reclinate while of bendable portion 62 places, projection 64a, 64b forward guides 67a to along the 2nd spigot surface 68b, the downside of 67b.
At this moment, as Fig. 6 (d) and shown in Figure 7, roof pressure portion 61 nearby forces down ring gear 43 or arm 45 the position of engagement of follower gear 42 and driven wheel 27, thereby makes the nearby bending of the position of engagement of follower gear 42.Like this, follower gear 42 bears the load of magnetic tape tension etc. on the one hand, easily breaks away from the engagement with driven wheel 27 simultaneously, and cuts off from motor 10 to supply reel table 4 drive path.
Owing to be accompanied by the homing action of rewinding control lever 55, bend 56 leaves the engagement projections 50 of gear support 47, so, the elastic restoring force of joint 52 is rotated support member 47, and projection 64a, 64b leave guides 67a, 67b, the elastic restoring force of bendable portion 62 rises roof pressure portion 61 and resets to initial position, and follower gear 42 is also freed from pushing of top gets back to original shape, and follower gear 42 returns to the preceding disengaging configuration of engagement after breaking away from driven wheel 27.
As mentioned above, formation according to present embodiment, by making follower gear 42 move the engagement of carrying out 42 pairs of driven wheels 27 of follower gear along the sense of rotation of driven wheel 27, by using decontrol (guides 67a, 67b and roof pressure portion 61) roof pressure follower gear 42 meshes on facewidth direction releasing, then make follower gear 42 reset to the preceding disengaging configuration of engagement with resetting means (gear support 47 that comprises joint 52 parts) with elastic restoring force.
Therefore, make follower gear 42 operating physical force that crooked operating physical force moves much smaller than the sense of rotation that makes follower gear 42 contrary driven wheels 27 on facewidth direction, particularly, owing to only make a part of local bending of the ring gear 43 or the arm 45 of follower gear 42, so its operating physical force is extremely slight.But,,, when engagement releasing, can not apply big load to the mate of two gears 42,27 so can instantaneous disengaging mesh because the amount of movement of the facewidth direction of follower gear is very little yet.
But, because the nearby local bending of the mate of follower gear 42 makes it to be disengaged with the engagement of driven wheel 27, so, guarantee roomy space just need not under the situation that follower gear 42 integral body are moved vertically abreast, this just can dispose other functional parts outside the circuit block near follower gear 42, thereby is suitable for the miniaturization of device.
The present invention is not limited to the above embodiments, in the scope that does not deviate from its design, can implement various remodeling, for example: make the follower gear local bending and do not break away from engagement,, also can make whole follower gear break away from engagement along facewidth direction if the space is spacious and comfortable.
According to the present invention, when follower gear and driven wheel were out-of-gear, even act at rotary load under the state of follower gear, operating physical force was small as also can not to make the driven wheel reversing, but can make both instantaneous disengaging engagements.And in the time of out-of-gear, two side's gear meshing part can not be applied in big load, thereby can prevent the damage of gear.
In addition, because follower gear is to be made by the synthetic resin of energy elastic deformation, so, if only make its mate bending, just can reduce operating physical force further, also need not to obtain roomy space for follower gear mobile, this just further is suitable for the miniaturization of whole device.
Particularly being made for radial arm between the ring gear of follower gear and the wheel hub, owing to make mate crooked easily, this just more can alleviate operating physical force.
