The rear end of the both sides of clamper base plate 168 is respectively equipped with linking arm 171.Two linking arms 171 are configured as the surface perpendicular to clamper base plate 168, thereby in the face of two sidewalls 162 '.A rest pad 172 is arranged on the clamper base plate 168, faces each linking arm 171 with predetermined spacing.

Clamper base plate 168 is provided with the medium disc sensor 173 that is used for the medium disc that sensing is held.Whether whether medium disc sensor 173 can have the medium disc being clamped by sensing, have the medium disc to be fed to client, or the like.Medium disc sensor 173 can be cooperated with the reflecting element 184 ' on the clamping limb 184, and plays the sensing effect, and this will be further elucidated hereinbelow.

A base plate rotation motor 175 that is used for transmission clamper base plate 168 is arranged on delivery tray 162.The driving force of base plate rotation motor 175 is by a plurality of gear transmission.Just, base plate rotation motor 175 is provided with motor gear 175 ', and the transmission shaft 176 that is installed on the delivery tray 162 is provided with one first shaft gear 176 ', and it is engaged in motor gear 175 '.The two ends of transmission shaft 176 also are respectively equipped with second shaft gear 177.Two second shaft gears 177 are engaged in the connection gear 178 that is installed on the delivery tray 162 respectively.Connection gear 178 is engaged in the transmitting gear 179 on the linking arm 171 that is arranged on clamper base plate 168.

Here, second shaft gear 177 and connection gear 178 all are to be rotatably supported on each gear carrier 180.Gear carrier 180 is mounted on the delivery tray 162.A side of gear carrier 180 extends between linking arm 171 and rest pad 172.And another side of gear carrier 180 also is used for the output shaft of bearing plate rotation motor 175.Such gear carrier 180 is respectively to be provided with one at the two ends of delivery tray 162.

Transmitting gear 179 is mounted to one with gear shaft 179 ', and it is with linking arm 171 and rest pad 172 actions.That is to say that linking arm 171, rest pad 172, gear shaft 179 ' and transmitting gear 179 all rotate together.But gear shaft 179 ' can rotate with respect to the sidewall 162 ' of gear carrier 180 and delivery tray 162.

The following describes the structural arrangement of the rotation that is used to control clamper base plate 168.Several clamping sensors 182 are arranged on the delivery tray 162, near each linking arm 171.Each gear shaft 179 ' is provided with a sensing block 183, and its light that can be selectively located clamping sensor 182 penetrates between part and the light receiving unit.Here, although two clamping sensors 182 are to be installed on the delivery tray 162 with same direction, each sensing block 183 can be stretched out to different directions at 90 degrees to each other.Because 168 of clamper base plates rotate and reverse in the angular ranges of 90 degree, its position is by two clamping sensors 182 sensing alternately.

Clamping limb 184 is to be installed in rotation on the clamper base plate 168. just, the two ends of arm rotation axis 185 that are installed on the rear end of clamping limb 184 are to be rotatably supported in respectively on the frame support bracket 185b of clamper base plate 168.

The shape of clamping limb 184 can prevent its when rotating with stack wheel 110 and interfere.In other words, in this embodiment, clamping limb 184 is branched off into three parts.These from clamping limb 184 branches come out partially-formed for not overlapping with the anti-groove 168 ' of interfering.Reflecting element 184 ' is arranged on the clamping limb 184, and its position is corresponding to the medium disc sensor 173 of clamper base plate 168.The effect of reflecting element 184 ' is the light receiving unit that the light from the light emission part is reflexed to medium disc sensor 173.Owing to have reflecting element 184 ', it is just passable that a medium disc sensor 173 only is set on the clamper base plate 168.

The driving force that clamping limb 184 is rotated is produced by the arm rotation motor 186 that is installed on the clamper base plate 168.The driving force of arm rotation motor 186 is delivered to the rotation axis gear 185 ' that is arranged on the arm rotation axis 185 by motor gear 186 ' and connection gear 187.So, rotate with clamping limb 184 at the effect underarm rotation axis 185 of the driving force of arm rotation motor 186.

The following describes the structural arrangement of the action that is used to control clamping limb 184.Among each frame support bracket 185b any all is equipped with two with respect to the arm sensor 189 of arm rotation axis 185 apart from one another by 90 °.Arm rotation axis 185 is provided with sensing block 190 (see figure 10)s.In other words, two arm sensors 189 are arranged on the movement locus of sensing block 190, and therefore, arm sensor 189 can sense the position of sensing block 190 according to the rotation of arm rotation axis 185.

Clamping limb 184 is provided with several promotions and refers to 192.Each promotes to refer to that 192 shape is a curved surface, makes its front end can produce predetermined elasticity power.Each promotion refer to 192 be configured as not overlapping with the anti-interference groove 168 ' of clamper base plate 168.In this embodiment, integrally be formed with four promotions and refer to 192, they are arranged on the correspondence position on the surface of clamper base plate 168.

Each promotes to refer to 192 by each elastic supporting piece 194 supporting and be installed on the clamping limb 184.In this embodiment, elastic supporting piece 194 is to be sleeved on the elastic support shaft 193, and the latter's two ends are to be bearing on the clamping limb 184.Each elastic supporting piece 194 can rotate around elastic support shaft 193, so their end can promote to refer to that 192 also produce elastic force thus.Each promotes to refer to that 192 effect is that the medium disc is pressed on the clamper base plate 168 how much medium disc quantity between pepe gripper base plate 168 and the clamping limb 184 is not.

Below, will describe so work of the media dispenser of the present invention of structure in detail.

In media dispenser of the present invention, the medium disc is one by one to be separated from a media disc sheet box by client operating, by transmitting module, then by carrying module 1 to transmit.In carrying module 1, the medium disc is sent to subsequently by belt conveyor 50 guiding and stacks wheel 110.Being sent to quantity that the medium disc that stacks wheel 110 will buy according to client stacks and is stacking on the module 3.Transmit to stack by the gripper 160 of delivery clamp module 5 and stacking the medium disc on the module 3 and flowing to client.

Below, the medium disc of the quantity that how will buy client with reference to Figure 11 a to 11i explanation stacks and is stacking on the module 3 and flowing to client.

At first, stacking on the plate 140, driver plate 138, stacking plate 140 and gripper 160 and all should be positioned at separately initial position for several medium discs are stacked.Such state is shown in Figure 11 a.In other words, driver plate 138 and stack plate 140 and move to as close as possible separating plate 124.Gripper 160 is positioned at it by that central in each magnetic field sensor 164 ' sense position.

In addition, the clamper base plate 168 vertical ground of gripper 160 hang downwards.It is to be in such state, and the sensing block 183 that is in relative right side under this state in Fig. 9 is by corresponding clamping sensor 182 sensings.

Also have, so clamping limb 184 is to be parallel to delivery tray 162., clamping limb 184 and clamper base plate 168 are mutually perpendicular.

At this state, one by one injected between each the tangential fin 112 that respectively stacks wheel 110 by the medium disc between the second and the 5th medium disc guiding piece 62 and 75.Then, make by CD-ROM drive motor 100 respectively to stack wheel 110 and rotate, the medium disc is transmitted by respectively stacking wheel 110.

Run into separating plate 124 if injected the medium disc that also rotates between each tangential fin 112, the medium disc just is located away from and respectively stacks wheel 110.Separated plate 124 is located away from the medium disc that respectively stacks wheel 110 in the process of each tangential fin 112 of being pushed respectively to stack to wheel 110 by push rod 147 continuously, by the inclined surface guiding of separating plate 124.

So the medium disc is supported and is erected at and stacks on the plate 140, respectively stacking between wheel 110 and the push rod 147.By this way, several medium discs are erected at continuously one by one and are stacked on the plate 140.Here, push rod 147 pushes away and is erected at the medium disc that stacks on the plate 140, makes its each tangential fin 112 of contact closely.Figure 11 b has expressed several medium discs and has been erected at and stacks on the plate 140.

But, increasing if be erected at the medium disc quantity that stacks between wheel 110 and the push rod 147, push rod 147 is just to pusher.That is to say that when spindle moving part 146 was pushed, coupling shaft 148, connecting rod 150 and pitman shaft 151 overcame the elastic force of elastic component 154 and also be pushed.So, pitman shaft 151 according to the quantity of the medium disc of erectting in 153 li motions of slotted hole.

If the medium disc of client's requirement is to stack stacking on the plate 140, just be stopped by the medium disc transmission of carrying module 1.Then, clamping limb 184 rotates.Clamping limb 184 is rotated by the driving force of arm rotation motor 186.That is to say that the driving force of arm rotation motor 186 is delivered to arm rotation axis 185 by motor gear 186 ', connection gear 187 and shaft gear 185 '.Because arm rotation axis 185 is an integral body with clamping limb 184, the rotation of arm rotation motor 186 will make clamping limb 184 rotate.Promotion refers to that 192 also rotate thereupon.

Because clamping limb 184 and promotion refer to that 192 rotate, the medium disc enters with clamper base plate 168 and contacts closely.Specifically, promote to refer to that 192 rely on the elastic force of himself and the elastic force of elastic supporting piece 194 that medium disc pressure is pushed to clamper base plate 168, and no matter how much quantity of medium disc is.Such state representation is in Figure 11 c.

As a reference, the medium disc that Figure 12 a expresses relative lesser amt is clamped in the state of 168 li of clamper base plates, and 12b expresses the state that the medium disc of relative a greater number is clamped in 168 li of clamper base plates.Shown in this two figure, be to refer to that by each promotion 192 medium discs push clamper base plate 168 to.

Then, each spindle moving part 146 rotates.Spindle moving part 146 is owing to the motion of driver plate 138 is rotated, and the latter's motion is by the drive force of CD-ROM drive motor 130.That is to say that the driving force of CD-ROM drive motor 130 is to be delivered to transmission shaft 136 by motor gear 132 and first and second connection gear 135 and 135 '.The driving force that is delivered to transmission shaft 136 is delivered to tooth bar 139 and 139 ' by the transmission gear 137 and 137 ' that is arranged on the transmission shaft 136 again.So the driver plate 138 that is provided with tooth bar 139 is stacking motion on the base plate 120.Driver plate 138 will move to first sensing block 157a always and be held sensor 158 and sense.Such state representation is in Figure 11 d.

At the state that spindle moving part 146 tilts to the rear end that stacks base plate 120, the right side motion of gripper 160 in figure, clamper base plate 168 deasil rotates simultaneously.Such procedural representation in Figure 11 e to 11g.

Then, gripper 160 is carried motor 165 to drive by dish.In other words, dish carries the driving force of motor 165 to be delivered to one of each tooth bar interconnection gear 166 ' by motor gear 165 ', thereby carries transmission shaft 166 to rotate.Carry the rotation of transmission shaft 166 that each tooth bar interconnection gear (rack interconnecting gear) 166 ' of each tooth bar that is engaged in respectively on the clamper guiding piece 20 is moved, thereby gripper 160 is also moved.

Gripper 160 will move to gripper 160 as described above always and be sensed by leftmost that in each magnetic field sensor 164 ' among Fig. 3.In the position that gripper 160 is sensed by that magnetic field sensor 164 ', support and be prevented from by extension 169 to the whereabouts by the clamping limb 184 of gripper 160 and the medium disc of clamper base plate 168 clampings.

In addition, extension 169 kaysers can not stretch out in clamper guiding piece 20 in the part of clamper guiding piece 20, thereby just the medium disc stretches out.That is to say, extension 169 stick into clamper guiding piece 20 front end that part and relatively withdraw along clamper base plate 168.In other words, extension 169 is relatively to withdraw along guide rod 170, makes elastic component 170 ' elastic deformation simultaneously.Such state representation is in Figure 11 i.So client has only just upwards to carry with handgrip medium disc and can take out the medium disc.

Next, if client takes out the medium disc, gripper 160 is motion in the opposite direction just.This motion of gripper 160 makes extension 169 reach its initial position.Gripper 160 is to carry the drive force of motor 165 to its original state by dish.That is to say that media dispenser has carried out the preparation that stacks the medium disc for next bit client's purchase.In other words, media dispenser has become the state shown in Figure 11 a.Here, each spindle moving part 146 is driven the original state of the drive force of motor 130 to them.

Simultaneously, if also do not take the medium disc away the state client shown in Figure 11 i.The medium disc just will be return and be sent to returns box 4.Such process is carried out conversely with the order from Figure 11 i to Figure 11 d.

At the state shown in Figure 11 d, CD-ROM drive motor 130 makes the direction motion of driver plate 138 to CD-ROM drive motor 130.Spindle moving part 147 no longer rotates, but keeps its corner that has rotated with driver plate 138 motions.Here, the interconnect block 138m of driver plate 138 is fastened togather mutually with the interconnect block 141 that stacks plate 140, stacks plate 140 so driver plate 138 can drive.

Stacking plate 140 is moved by guide rod 142 guiding.Specifically, while stack plate 140 and move and make restoring piece 143 elastic deformations.The 3rd the sensing block 157c that driver plate 138 will move to it always drawn off sensor 159 and sensed.

Simultaneously, be to be in the state shown in Figure 13 a and the 13b if stack plate 140, return notch 126 and just be opened.So, can be returned to and return 4 li in box by returning notch 126 by the medium disc of clamper base plate 168 and clamping limb 184 clampings.As a reference, returning box 4 can be provided with one and be used to receive by the import of returning the medium disc that belt 85 returns and another and be used to be received in the import of one pile of medium disc on the gripper 160.

If clamping limb 184 is raised at the state shown in Figure 13 a and the 13b, will falls into and return box 4 by returning notch 126 by the medium disc of clamper base plate 168 and clamping limb 184 clampings.Here, the rotation that stacks wheel 110 can make all medium discs enter and return box 4.

If the medium disc has been return fully, for being erected at the medium disc, the purchase of giving the next bit client stacks on the plate 140, and each element will move to their original state shown in Figure 11 a.Here, if because driver plate 138 moves to its initial position, interconnect block 138m and 141 is no longer engaging mutually, stacks plate 140 and just moves to its initial position under the effect of the elastic force of restoring piece 143.

In addition, spindle moving part 146 is mounted to such: according to the relation of the position between the position that stacks plate 140 and driver plate 138 and connecting rod 150, coupling shaft 148 and the elastic component 154, it makes push rod 147 favour and stacks wheel 110.

Simultaneously, in the present invention, can do different settings to the direction that the medium disc flows to client.That is to say,, both can carry the medium disc also and can carry to the right-hand member direction of clamper guiding piece 20 to its left end direction by Fig. 2.Here illustrated is the structural arrangement that the medium disc is carried to the left end direction of clamper guiding piece 20.

But Figure 14 expresses, and gripper 160 is assembled into the medium disc is carried by the right-hand member direction to clamper guiding piece 20.As shown in the drawing, transfer dish 162 has rotated 180 °, carries that surface of motor 165 to keep up and be provided with dish.So dish is carried the direction of motor 165 to become and is turned around.

Then, can after making each gear shaft 179 ' disengaging, be assemblied in transfer dish 162 to clamper base plate 168 conversely.Why can do like this, be because those parts that are engaged in transfer dish 162 of clamper base plate 168 are to be designed to symmetry and identical mutually.So when the top of clamper guiding piece 20 is watched, clamper base plate 168 is to be positioned at relative top, and clamping limb 184 is to be positioned at relative bottom.At such state,, just can flow to client to the medium disc to the right-hand member direction of clamper guiding piece 20 if gripper 160 is installed in 20 li of clamper guiding pieces.

In such structural arrangement, original state is that clamper base plate 168 is erected at the top that stacks plate 140 vertically, and clamping limb 184 flatly be positioned at transfer dish 163 lower surface below.In addition, follow-up action according to preceding structure in identical order carry out.In this embodiment, extension 169 guides top rather than its underpart of medium disc naturally.

Can expect: the media dispenser of so constructing according to the present invention has following advantage.

In the present invention, stack most of elements of module, stack on the base plate and be fixed in two guide plates except that transmitting module and carry the module, all being mounted in.Delivery clamp module is to refill gripper by the upper end that the clamper guiding piece is installed in two guide plates to form.Like this, constitute because this media dispenser is a part by several modules, an one advantage is that I﹠ M is all very convenient.

Particularly, such advantage is arranged, be used for direct clamping exactly and stack and stacking the medium disc on the module and the structure that they flow to client's delivery clamp module relatively simplified.
