The transport process of path CD is as follows:

Fig. 3 has shown that path CD D1 is inserted into 4 o'clock the state of mouth that inserts, and two test rods 11,12 are compressed the direction fine rotation of Xiang Suoding by the periphery of path CD when the front end of path CD D1 inserts between transfer roller 5 and the guided plate 6.At this moment the plate 13 that links slightly moves right because of the rotation of test rod 11,12, moves by this sliding panel 20 is moved to inserting oral-lateral by web joint 21.By moving of sliding panel 20, operating sheet 20b connects the 3rd switch 22, makes the CD-ROM drive motor starting.So transfer roller 5 begins rotation path CD D1 is introduced the insertion mouth, and path CD D1 is transmitted to device inside.On the other hand, the slight interlock plate that moves 13 keeps the tongue piece 13a and the first plectrum 17a not to mesh.Therefore, the first guide plate 17b of first guide member 17 is positioned within the transmission lines of CD.

In addition, because 20 of sliding panels have moved a little, so the first lug 20a and the second plectrum 18a do not mesh.Therefore the second guide plate 18b of second guide member 18 also is positioned within the transmission lines of CD.At this moment, second rotor plate 28 of clip 27 is inverted the turned position that spring 30 is limited in a direction, contacts with the top of top board 2 because slip sheet 31b, and the leading section 31c of hold assembly 31 rises to clip 27 a top side of top board 2.Therefore, 27 contacts of path CD D1 discord clip, but guided by first guide member 17 and second guide member 18, be sent to the centre (as shown in Figure 4) of clip 27 and plummer 3.On the other hand, clip 27 is held parts 31 and is clamped on the plummer from three directions, therefore, can keep its rotation center consistent with the rotation center of plummer 3.

Fig. 5 has shown that catch 19a that path CD D1 is sent to its periphery and path CD baffle plate 19 touches the state of position.At this moment, the rotation axis 23d of start-up plate 23 is placed in motionless state by the slotted hole 2a and the second circular hole 24b.On the other hand, the front end of path CD D1 presses the cylinder 23a of start-up plate 23, is the center with rotation axis 23d, makes start-up plate 23 by counterclockwise rotating.Because the counter clockwise direction of start-up plate 23 is rotated, projection 23c presses the edge of crank hole 9b one side of control panel 9, and control panel 9 is moved to inserting a mouthful direction.Touched to inserting the control panel 9 that mouthful direction moves, the transmission of power that is activated motor begins to move to inserting a mouthful direction, and then, first of control panel 9 presses sheet 9c and 29 engagements of the 3rd rotor plate, makes the 3rd rotor plate 29 to counterclockwise rotating.Along with the rotation of the 3rd rotor plate 29, second rotor plate 28 rotates to clockwise direction.At this moment, the following of path CD supported by the tab 23b shown in Fig. 5 B.

When this second rotor plate 28 rotated, cam 9a and 8 engagements of transfer roller support plate made transfer roller 5 leave guided plate 6.Simultaneously, crank hole 9b makes the cylinder 23a of start-up plate 23 rotate approaching to top board 2 one sides.By the rotation of this start-up plate 23, tab 23b when the face of path CD D1 is supported to moving with transfer roller 5 identical directions.Then, along with the rotation of second rotor plate 28, hold assembly 31 slip the incision hole that sheet 31b falls into top board 2.So the leading section 31c of hold assembly 31 makes path CD and clip 27 simultaneously approaching to plummer 3 as shown in Figure 6 under the effect of bar springs 32.At this moment, the rotation center of clip 27 keeps consistent with the rotation center of plummer 3 and approaching to plummer 3 centers by hold assembly 31.At this moment, path CD D1 transports on the plummer 3 by two catch 19a, the first guide plate 17b about plummer of equipment inboard, the guiding of the second guide plate 18b.Therefore, free under the state of clamping even transfer roller 5 breaks away from guided plate 6, path CD D1 still is sent on the plummer 3 under the clamp position of tab 23b, clip 27 and transfer roller 5 exactly.

Fig. 7 has shown the broadcast state of path CD.Path CD D1 is clamped on the plummer 3 by the permanent magnet of clip 27.When the center pit of path CD D1 is directed to the centered cylinder of wedge surface 3c and plummer 3 when chimeric, the path CD by wedge surface 3c be pulled back to insert oral-lateral some.Retract action by this, the periphery of path CD breaks away from from catch 19a.On the other hand, projection 23c is pushed to the opposite side of crank hole 9b, and start-up plate 23 continues by counterclockwise rotating, and cylinder 23a is broken away from from the periphery of path CD fully.In addition, as shown in Figure 8, transfer roller 5 and tab 23b also break away from from the face of path CD D1, move to the position that can not hinder path CD D1 rotation.

On the other hand, along with the clockwise direction of second rotor plate 28 is rotated, the protrusion tab 2d of back shaft 31a and top board 2 touches, and each hold assembly 31 is that the center rotates counterclockwise with square hole 28b.Rotate by this, the leading section 31c of each hold assembly 31 withdraws from annular groove 27b.Because leading section 31c withdraws from annular groove 27b, the unitary rotation of clip 27 and plummer becomes possibility.In addition, in the process that second rotor plate 28 moves in the direction of the clock, make the counter-rotating of counter-rotating spring 30, by the power of this counter-rotating spring 30, the leading section 31c of second rotor plate 28 and each hold assembly 31 is maintained at the state that withdraws from the annular groove.Thereafter, the 3rd presses sheet 9e makes 26 actions of the 4th switch, and the rotation of CD-ROM drive motor is stopped.

As mentioned above, Yi Bian path CD D1 be sent on the plummer 3 on one side by first guide plate 17b about two catch 19a of device inboard, plummer and second guide plate 18b guiding.Therefore, even transfer roller 5 breaks away from from guided plate 6, make clamp position liberation, the path CD still can be sent on the plummer exactly.The transport process of this CD, no matter what kind of posture disk player is in, and can carry out exactly.Therefore, no matter what kind of posture playing device is in, and this load mode can be carried out exactly.And two catch 19a and the first guide plate 17b, the second guide plate 18b do not move when the path CD transmits, so design easily.In addition, in present embodiment, the position of stipulating the first guide plate 17b and the second guide plate 18B is positioned at CD transmission lines intersection and by on the center line of plummer, but, its position is not geometric straight line, so long as the path CD can be sent to position on the plummer, on direction of transfer before and after some error also can.In addition, though be to make first guide member 17 and 13 engagements of interlock plate, and 12 engagements of right test rod are also passable.

The transport process of big footpath CD is as follows:

Fig. 9 has shown the state when big footpath CD D2 transports from inserting mouth 4 by transfer roller 5.Two test rods 11,12 and big footpath CD D2 periphery offset, and rotate significantly.Because of this rotates significantly, interlock plate 13 also moves significantly, and tongue piece 13a and first plectrum 17a engagement are rotated first guide member 17, and the first guide plate 17b is withdrawed from from the CD transmission lines.In addition, sliding panel 20 moves significantly and causes the first lug 20a and second plectrum 18a engagement, and second guide member 18 rotates, and the second guide plate 18b is withdrawed from from the transmission lines of CD.Further, because of moving significantly of sliding panel 20, cause the second lug 20c and the 3rd plectrum 19c engagement, path CD baffle plate 19 also rotates, and catch 19a is withdrawed from from the transmission lines of CD.Then, first recess 20d of sliding panel 20 and the support 24d of first rotor plate 24 engagement, making first rotor plate 24 is the center with axle 24a, by counterclockwise rotating.By the rotation of this first rotor plate 24, the rotation axis 23d of start-up plate 23 is positioned at the position of the second circular hole 24b and straight hole intersection point, becomes movable state.Subsequently, start-up plate 23 is the center with the edge contact point of projection 23c and crank hole 9b one side, rotates while rotation axis 23d is moved in straight hole 24c and slotted hole 2a.

State after Figure 10 has shown big footpath CD D2 and big footpath CD baffle plate 7 contacts.At this moment, support 24e limits returning of sliding panel 20 by the recess 24d of the rotation axis 23d and first rotor plate 24 is chimeric, therefore, left and right sides test rod 11,12 is trapped in the position after rotating significantly, and detection lug 11b, 12b are broken away from from the periphery of big footpath CD D2.On the other hand, the terminal of rotation axis 23d and slotted hole 2a touches, and anticlockwise rotation takes place start-up plate 23, and control panel 9 is moved to the direction of inserting mouth 4.In the moving of this control panel 9, the transmission of power of CD-ROM drive motor is to control panel 9, makes control panel continue to move to inserting mouthfuls 4.Then, the situation during with transmission path CD is identical, and the CD holder device action carries out the big directly clip of CD.Thereafter, the 3rd presses sheet 9e makes the action of the 4th switch 26, and the rotation of CD-ROM drive motor is stopped.

This disk player is provided with on a pair of test rod 11,12 and presses the 11e of portion, 12e, on interlock plate 13, added and to have realized first contacting part 13b of clutch and the second contacting part 13c that left side test rod 11e realizes clutch with the 12e of the portion that presses of right side test rod, when two test rods 11,12 do not rotate, place on the straight line that connects two test rods, 11,12 rotating fulcrum 11d, 12d as long as will respectively press the 11e of portion, 12e, just can realize CD being guided to the center of insertion mouth and CD being sent on the plummer quickly and safely.

And, the CD holder device by clip 27, be fixed on second rotor plate 28 that the central authorities of top board 2 can freely rotate, with the action of control panel 9 by the counter-rotating spring 30 that first presses the 3rd rotor plate 29 that sheet 9c passes to second rotor plate 28, second rotor plate 28 is remained on rotate terminal location, be installed in three hold assemblies 31 on second rotor plate 28, give leading section 31c with these hold assemblies 31 and be clamped in the power of annular groove 27b bottom direction and give clip 27 is constituted to the bar springs 32 of the approaching power of plummer direction by back shaft 31a.When CD being carried out clip by this formation, under the state that is consistent at center with the center of clip and plummer, make clip approaching to plummer, after CD is clamped on the plummer, the hold mode of clip is removed, so the clip action can be not limited to the posture of playing device and carry out exactly.In addition, when not tightening CD, clip is by the hold assembly hold mode, so even playing device is subjected to also can not producing noise from the vibrations of outside, and this technology can be used to play the disk player of the different CD of external diameter.

In the present embodiment, in CD transports circuit, transport with CD that circuit intersects and by on the straight line at plummer center, as long as be equipped with the engagement of the periphery of path CD, can set first, second guide member with both spacings of path CD holder on plummer, just can Without wishing and the posture of device, the path CD is carried out the dvd playback action.

The utility model generally is used for the family expenses disk player, also can be used on the vehicle mounted disk player.
