When Figure 22 a to Figure 22 d is depicted as and dismantles cartridge from electronic imaging apparatus, rotating driving force receiver 12 and revolving force driving head 3 out-of-gear process gradually.Figure 22 a is that rotating driving force receiver 12 is still in the schematic diagram of engagement with revolving force driving head 3; Figure 22 b be rotating driving force receiver 12 with revolving force driving head 3 just in out-of-gear view; Figure 22 c is rotating driving force receiver 12 and revolving force driving head 3 out-of-gear view, but rotating driving force receiver still with the contact of incline plane of inverted V-shaped 51; Figure 22 c be rotating driving force receiver 12 no longer with the contact of incline plane of inverted V-shaped 51, now rotating driving force receiver 12 recovers vertical state under the effect of Compress Spring.
The α of deflection angle shown in Figure 23 is angle between the axis L1 of diagram the photo-sensitive cell 11 and axis of rotation L2 of rotating driving force receiver 12, and the size of deflection angle α can change along with the state of the installation and removal of cartridge.The maximum deflection angle of deflection angle α by driving force transmit pin 14 and the symmetric fanning of rotating driving force receiver 12 slot 1211 opening angle δ limit, the axis of rotation L2 of rotating driving force receiver 12 swings relative to the power transmission pin 14 of horizontally set along with groove 1211 and the action relative to photo-sensitive cell axis L1 inclination occurs, simultaneously also relative to the axis run-off the straight of power transmission pin 14; And when maximum deflection angle, rotating driving force receiver 12 does not touch the edge 115 of photo-sensitive cell gear 11 and the edge 156 of spheroid postive stop baffle 15.The size of the opening angle δ of groove 1211 can limit the angle of rotating driving force receiver 12 beat.Angle δ is larger, and deflection angle α maximal value is larger, and α=δ/2; But when angle δ is excessive, deflection angle α increases, rotating driving force receiver 12 is caused to touch the edge 115 of photo-sensitive cell gear 11 or the edge 156 of spheroid postive stop baffle 15, now, the maximum pendulum angle of rotating driving force receiver 12 is subject to the restriction at the edge 115 of photo-sensitive cell gear 11 or the edge 156 of spheroid postive stop baffle 15, and the opening angle δ of groove 1211 does not recur the effect of angle of restriction deflection angle; The maximum pendulum angle of rotating driving force receiver 12 is also subject to the restriction of the narrowest place distance m of groove simultaneously, in order to the restriction making the pivot angle of rotating driving force receiver 12 only be subject to sector open δ, such relation should be there is: m>d between the outside diameter d that the narrowest place distance m of groove and driving force transmit pin 14, and d/m=cos α or be slightly less than cos α, namely m is desirable than theoretical value slightly larger value.Described α angular range is between 15 degree to 30 degree, and now, when α gets maximal value 30 degree, supposing that the present embodiment medium power transmits the diameter d of pin 14 is 2mm, then m value is 2.4mm, or more bigger than 2.4, can value be 2.5 or 2.6mm; When α gets minimum value 15 degree, then the desirable 2.1mm of the value of m, or more bigger than 2.1, value is 2.2mm or 2.3mm; In the present embodiment, preferred α is 28 degree, and the diameter d value of power transmission pin is that 2mm, m value can be 2.3mm, but gets the value 2.5mm more bigger than 2.3 in the present embodiment; Generally speaking, the narrowest place distance m of groove the desirable theoretical value of value or get the value of 0.1-0.2mm slightly larger than theoretical value; M>d, and d/m=cos α or be slightly less than cos α, can reduce the friction between pin 14 and groove simultaneously, avoids m increase and cause rotating driving force receiver 12 to increase relative to the end play of photo-sensitive cell gear.
The portion size relation of each parts of Figure 24 display driver force transfer unit 1.Wherein, the external diameter of the first step 124 of rotating driving force receiver 12 is D1, and the central diameter of Compress Spring 13 is D2, and D2<D1, spring 13 conflict step surface 1241 all the time can be made, the internal diameter of flexible member retention groove 154 is D6, and the internal diameter of Compress Spring 13 is D7, and D7 equals or is slightly smaller than D6, Compress Spring 13 is loaded flexible member retention groove 154 and the object of not easily deviating to reach, distance between the limiting section 152 of spheroid 121 is L, and the diameter of spheroid 121 is D3, wherein L<D3, and spheroid can be made not deviate from, the diameter of spheroid holding surface 111 is D4, the diameter of spheroid limiting section 152 arc surface is D5, wherein D4 and D5 is equal, and be a bit larger tham the diameter D3 of spheroid, namely there is small gap between spheroid and its retainer face to be convenient to rotating driving force receiver 12 and to realize swinging, and, carry out radial and axial spacing by spheroid holding surface 111 and limiting section 152 acting in conjunction of spheroid postive stop baffle to the spheroid rotating drive Receiver 12, control the shifting amount relative to photo-sensitive cell gear rotating drive Receiver 12, cause power transmission not steady to prevent shifting amount excessive.Power transmission pin 14 is arranged on the center that spheroid keeps sphere 111, rotating driving force receiver 12 swings in the plane of the axis perpendicular to power transmission pin 14, as shown in Figure 25 dotted line, now maximum deflection angle α is subject to the restriction at the edge 115 of photo-sensitive cell gear 11 or the edge 156 of spheroid postive stop baffle 15.Because Compress Spring 13 has certain decrement after mounting, can absorb because the gap between spheroid 121 and its holding surface 111 causes rotating driving force receiver 12 relative to the axial movement value of photo-sensitive cell gear 11, can realize making power transmission object more stably.
No matter being installed in the process of electro-photographic image forming apparatus or in the unloading process of cartridge at cartridge, all deflection angle is produced between rotating driving force receiver 12 and photo-sensitive cell gear 11, and utilize technical scheme of the present invention, rotating driving force receiver can tilt to any direction relative to the axis of photo-sensitive cell gear, facilitates the installation and removal of cartridge.As shown in figure 23, power transmission pin 14 is fixedly fitted to the inside of photo-sensitive cell gear relatively through spheroid, its radial and axial activity is subject to the restriction of pin retention groove, rotating driving force receiver 12 can tilt relative to the axis L1 of photo-sensitive cell gear with in the plane of the crossing composition of axis L1 of photo-sensitive cell gear at the axis of power transmission pin 14, its maximum tilt angle is by the restriction of the opening angle δ scope of groove 1211, and simultaneously rotating driving force receiver 12 can the axis L1 place of photo-sensitive cell gear and with the plane of the axes normal of power transmission pin 14 in tilt relative to the axis L1 of photo-sensitive cell gear, the angle of inclination of both direction combines the universal swing function just making this driving force transmitting assembly have universal joint, namely the axis of rotation L2 of rotating driving force receiver 12 can do the inclination of any direction relative to the axis L1 of photo-sensitive cell gear 11, show that the swing of either direction can be decomposed into the inclination of above-mentioned both direction simultaneously.
According to the present invention, even if those skilled in the art are easy to expect the function that technical scheme of the present invention is cancelled described flexible member and still made rotating driving force receiver realize its axis to swing relative to any direction that the axis of photo-sensitive cell gear makes certain angle; And by technical scheme of the present invention, relative to driven unit, there is axis due to power transmission pin and radial direction is spacing, and the power pin described by the technical program and the matching relationship between the groove of spheroid, can be easy to expect, even if cancel spheroid limiting section, the axial float of rotating driving force receiver is limited to power transmission pin, and radial-play is still limited to spheroid and keeps sphere.
