To the process how cartridge with the above driving force transmitting assembly being installed in electronic imaging apparatus be described below.Figure 19 is the structural representation of the revolving force driving head of electronic imaging apparatus, and wherein, 31 is driving force passing pin, and 32 is the taper surface matching with the conical socket 1262 of rotating driving force receiver.Figure 20 is that cartridge is (not shown, can be according to the position of the position judgment cartridge of photo-sensitive cell 4) along directions X, be assembled to the schematic diagram in electronic imaging apparatus (not shown), 5 is the guide rail of the installation cartridge of electronic imaging apparatus in prior art.Described guide rail has inverted V-shaped part 51 as shown in figure 20, is provided with inclined-plane 511 and 512 on it.As shown in figure 20, rotating driving force receiver 12 is under the maintenance of Compress Spring 13, in the process of installing, and touch the inclined-plane 511 of guide rail inverted V-shaped at rotating driving force receiver 12 before, rotating driving force receiver 12 keeps the state (as shown in Figure 21 a) not tilting always, and its axis of rotation L2 keeps coaxial with the axis L1 of photo-sensitive cell gear; After rotating driving force receiver 12 touches the inclined-plane 511 of inverted V-shaped 51, rotating driving force receiver 12 starts run-off the straight, inclined-plane 512 can make to be inclined to the side that rotary driving force acceptance division 126 is more close to the revolving force driving head 3 of electronic imaging apparatus, as shown in Figure 21 b; Continue cartridge is installed, as shown in Figure 21 c, rotating driving force receiver 12 starts to touch the schematic diagram of revolving force driving head 3, and now rotating driving force receiver 12 starts to reduce with respect to the deflection angle of photo-sensitive cell gear 11; After cartridge is in place, rotating driving force receiver 12 is realized engagement with revolving force driving head 3, as shown in Figure 21 d, now, the axis L3 of revolving force driving head 3 is coaxial with the axis L1 of the axis of rotation L2 of rotating driving force receiver and photo-sensitive cell gear; Now, when electronic imaging apparatus work, revolving force driving head 3 rotarily drives rotating driving force receiver 12 rotations, thus 4 rotations of dynamic optical element.During rotary actuation, the driving force passing pin 31 on revolving force driving head 3 and dip plane 12611 interlocks of claw 1261, and rotary driving force is passed to claw 1261 by dip plane 12611.Claw 1261 passes to transmission of power pin 14 by rotating driving force receiver 12 after receiving driving force again, by pin 14, by pin, keep groove 113 and 153 that rotary driving force is passed to photo-sensitive cell gear 11 again, dynamic optical element 4 rotates (as shown in figure 20) simultaneously, and photo-sensitive cell gear is coaxial with the axis L1 of photo-sensitive cell.
Figure 22 a to Figure 22 d is depicted as while dismantling cartridge from electronic imaging apparatus, and rotating driving force receiver 12 and revolving force driving head 3 be out-of-gear process gradually.Figure 22 a is rotating driving force receiver 12 and the revolving force driving head 3 still schematic diagram in engagement; 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 contacts with the inclined-plane of inverted V-shaped 51; Figure 22 c is that rotating driving force receiver 12 no longer contacts with the inclined-plane of inverted V-shaped 51, and 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 diagram the axis L1 of photo-sensitive cell 11 and the 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 transmits pin 14 by driving force and limits with the opening angle δ of the fan-shaped fluting 1211 of symmetry of rotating driving force receiver 12, the axis of rotation L2 of rotating driving force receiver 12 is along with groove 1211 swings with respect to the transmission of power pin 14 of horizontally set and the action that occurs to tilt with respect to photo-sensitive cell axis L1, simultaneously also with respect to the axis run-off the straight of transmission of power 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 restricting rotation driving force Receiver 12 beats angle.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, cause rotating driving force receiver 12 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 do not recur effect of angle of restriction deflection angle of the opening angle δ of groove 1211; The maximum pendulum angle of rotating driving force receiver 12 is also subject to the narrowest place of groove apart from the restriction of m simultaneously, in order to make the pivot angle of rotating driving force receiver 12 only be subject to the restriction of sector open δ, the narrowest place of groove is apart from having such relation: m>d between m and the outside diameter d of driving force transmission pin 14, and d/m=cos α or be slightly less than cos α, m is desirable than the slightly large value of theoretical value.Described α angular range be 15 degree between 30 degree, now, α gets maximal value 30 while spending, and supposes that the diameter d that the present embodiment medium power transmits pin 14 is 2mm, m value is 2.4mm, or more bigger than 2.4, can value is 2.5 or 2.6mm; α gets minimum value 15 while spending, 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, preferably α is 28 degree, and the diameter d value of transmission of power pin is 2mm, and m value can be 2.3mm, but in the present embodiment, gets than 2.3 bigger value 2.5mm; Generally speaking, the narrowest place of groove is apart from the desirable theoretical value of value of m or get than the value of the slightly large 0.1-0.2mm of 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 to increase and cause rotating driving force receiver 12 to increase with respect 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, can make spring 13 step surface 1241 of conflicting all the time, it is D6 that flexible member keeps the internal diameter of groove 154, and the internal diameter of Compress Spring 13 is D7, and D7 equals or be slightly smaller than D6, to reach, packs Compress Spring 13 into flexible member keep groove 154 and the object that is difficult for deviating from, distance between the limiting section 152 of spheroid 121 is L, and the diameter of spheroid 121 is D3, and wherein L<D3, can make spheroid not deviate from, it is D4 that spheroid keeps the diameter of face 111, the diameter of spheroid limiting section 152 arc surfaces is D5, wherein D4 equates with D5, and be a bit larger tham the diameter D3 of spheroid, be between spheroid and its retainer face, to exist small gap to be convenient to rotating driving force receiver 12 to realize swing, and, by spheroid, keep face 111 and limiting section 152 actings in conjunction of spheroid postive stop baffle to carry out radial and axial spacing to the spheroid of rotation drive Receiver 12, control the shifting amount with respect to photo-sensitive cell gear of rotation drive Receiver 12, to prevent that shifting amount is excessive and cause transmission of power not steady.Transmission of power 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 transmission of power 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 assembling, can absorb because the gap between spheroid 121 and its maintenance face 111 causes rotating driving force receiver 12 with respect to the axial movement value of photo-sensitive cell gear 11, can realize and make transmission of power object more stably.
No matter in the process that is installed to electro-photographic image forming apparatus of cartridge or in the unloading process of cartridge, between rotating driving force receiver 12 and photo-sensitive cell gear 11, all produce deflection angle, and utilize technical scheme of the present invention, rotating driving force receiver can tilt to any direction with respect to the axis of photo-sensitive cell gear, facilitates the installation and removal of cartridge.As shown in figure 23, transmission of power 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 that pin keeps groove, rotating driving force receiver 12 can tilt by the axis L1 with respect to photo-sensitive cell gear in the axis of transmission of power pin 14 and the crossing plane forming of the axis L1 of photo-sensitive cell gear, its maximum inclination angle is subject to the restriction of the opening angle δ scope of groove 1211, and rotating driving force receiver 12 can tilt by the axis L1 with respect to photo-sensitive cell gear in plane axis L1 place and vertical with the axis of transmission of power pin 14 of photo-sensitive cell gear simultaneously, the angle of inclination of both direction combines the universal swing function that just makes this driving force transmitting assembly have universal joint, the axis of rotation L2 that is rotating driving force receiver 12 can do with respect to the axis L1 of photo-sensitive cell gear 11 inclination of any direction, 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 technical scheme of the present invention, cancel described flexible member and still make rotating driving force receiver realize its axis to make with respect to the axis of photo-sensitive cell gear the function that any direction of certain angle swings; And by technical scheme of the present invention, because transmission of power pin has axially with radially spacing with respect to driven unit, and according to the matching relationship between the described power pin of the technical program and 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 transmission of power pin, and radial-play is still limited to spheroid and keeps sphere.
