Description
The present invention puts it briefly and relates to the dish ejecting structure of a kind of magneto optical driver (MODD), especially when because power interruption when causing can not the realization dish ejecting automatically, carry out the improvement of artificial dish this device when ejecting, and use a solenoid to realize that as the driving means of disc holder dish ejects automatically, come simplification device and improve usability with this.
Known as those of ordinary skill, magneto optical driver and magneto-optic disk use together, and the data on the dish are by laser beam and magnetic typing.When magneto optical driver used together with dish, disk drive should provide a kind of dish liftout attachment that can eject dish.
In common magneto optical driver, dish is to be carried in the cassette holder with hole, and its configuration of dish of using in magneto optical driver commonly used is similar to for example 3.5 inches disks that use in the typical personal computer in 3.This dish is disclosed in United States Patent (USP) 5021913 and 5036421.
Now proposed and be extensive use of the dish liftout attachment of the various modification of magneto optical driver.Shown in Figure 1 be a kind of dish liftout attachment commonly used for example.In order to eject the magneto-optic disk D that is contained on the disk drive loader mechanism, only show the carriage 10 of loader mechanism among the figure, dish ejects eccentric rod 45 and pushes the carriage one integrated pin 46 that ejects to back, and carriage 10 is retreated.Here, eccentric rod 45 is driven by the revolving force of a high deceleration motor, and the revolving force that ejects motor 44 that perhaps is installed on the basal surface of disk drive carriage 10 drives.Because the setback of carriage 10 so make breech lock 13 biasings at carriage 10 supporting rod 11 on one side, also just retreats and latch 13, this breech lock 13 is hinged on the loader mechanism by jointed shaft 12, and by a tension spring (not shown) biasing.So breech lock 13 is because the restoring force of its tension spring can flexibly be pressed (as Fig. 1 direction of arrow) rotation counterclockwise around jointed shaft 12.So the dish that is positioned at breech lock 13 basal surfaces ejects rod 14 and pushing away the back side of coil D and move forward, so automatically will coil D and eject disk drive.In Fig. 1, drawing reference numeral 47 expressions make the Spindle Motor of dish D rotation, and label 47 ' is represented magnet, is contained in the top surface of Spindle Motor 47, is used for fixing the recording surface that coils D; Label 48 expression pick-ups, label 49 expression laser focusing lens.
Dish at dish liftout attachment commonly used ejects in the operation, and Spindle Motor 47 need shut down before ejecting dish D.If when the dish D that is rotating is ejected device and ejects, do not stop Spindle Motor, and dish D still by the magnet 47 of Spindle Motor 47 ' folded the speeding up of magnetic force, and be forced to eject, this hour indicator is still rotating in the air high speed, so dish may be by badly damaged.
Be that solution dish D may impaired problem in ejecting operation, the dish liftout attachments that great majority are commonly used stop its Spindle Motor 47, and start it and eject motor 44, can eject dish D so automatically and unlikely damage dish D.
However, what dish liftout attachment commonly used was adopted is the select motor 44 that ejects from the high deceleration motor of costliness, so increased the expense of disk drive.
In addition, dish liftout attachment commonly used is to eject dish D by high deceleration being ejected the rectilinear motion that rotatablely moving of motor convert carriage 10 to, and therefore coiling liftout attachment need be equipped with the required add-on parts of rectilinear motion that converts carriage from rotatablely moving of motor to.The movement conversion part makes the production run of liftout attachment and operation complicated, therefore requires the smooth and accurate operation of liftout attachment not realize.
Make great efforts to solve above-mentioned because during problem that the movement conversion part is brought, the dish liftout attachment adopts solenoid to replace ejecting motor, for example No. the 12779/1993rd, the Jap.P. prospectus.But the dish liftout attachment still exists problem complicated and the dish ejecting mechanism that size is big except that using solenoid.Said apparatus is because the dish ejecting mechanism of big molded dimension brings a problem to be: with the recent development trend-compactedness of disk drive-run in the opposite direction.Another problem of this kind device is: liftout attachment can not bring the effect of reduction expense.Secondly, this liftout attachment does not have manually-operated means, and therefore this liftout attachment can not eject dish under the situation of outage.
For under the dish liftout attachment can not the situation of operation, for example owing to power failure or owing to the liftout attachment driving means breaks down, still need manually to eject dish D, the dish liftout attachment that great majority are commonly used can manually eject the pattern operation except ejecting automatically the pattern, but its automatic mode employing is the revolving force that ejects motor.
But in order to make liftout attachment also artificial mode operation except automatic mode, protecgulum 15 has constituted the front portion of disk drive, a undersized hole 16 is set, the internal communication of this hole 16 and disk drive in protecgulum 15.When need manually eject dish D owing to outage, in tapered pin anchor clamps 17 patchholes 16, push the push pedal of giving prominence in carriage 10 fronts 18 to back, so just can eject dish D in the artificially.
In any case but, this can artificial mode except that automatic mode dish liftout attachment under the operation hole 16 must be set; This hole is formed in the protecgulum 15, and and the internal communication of disk drive.Secondly also will be for disk drive is equipped with pin anchor clamps 17 separately, in order to avoid anchor clamps 17 dislocation or misalignments.Because pin anchor clamps 17 separate preservation with disk drive, the user uses other pointed tool to replace this special-purpose pin anchor clamps 17 usually, so just may cause damage dish liftout attachment and disk drive.
Therefore, the objective of the invention is to: a kind of dish liftout attachment of magneto optical driver is provided, and it can overcome above-mentioned defective, and the means that move forward and backward as carriage when ejecting pattern automatically adopt solenoid to replace the motor of using always that ejects; When manually ejecting pattern, being provided with one can open the door, so that manually eject dish D, has so just simplified its structure and has improved its usability.
For achieving the above object, the liftout attachment of magneto optical driver of the present invention or manually to eject pattern, by the operation breech lock magneto-optic disk is ejected, magneto optical driver is made of the solenoid unit, comprise a coil, this coil unit is arranged on the basal surface of the dish load carriage of disk drive, with the pattern of ejecting automatically carriage is retreated, and dish is ejected; Described solenoid unit also comprises a retractable hook stick, and itself and solenoid are coupled; A control lever is hinged on the center of disk drive pedestal, and the free end of one end and hook stick is hinged, when coil was unmagnetized, hook stick stretched out, when coil magnetizing, the hook stick withdrawal, along with stretching out and the action of withdrawing of hook stick, control lever will coil load carriage and move forward and backward; One can be opened the door, and is hinged on by bindiny mechanism on the edge of handle hole of disk drive protecgulum, and the size of described handle hole allows user's finger to pass through, and handle hole is located in the protecgulum, and handle hole is connected with the carriage push pedal; Can open the door is with manually actuated, and allows user's finger to pass through handle hole, promotes push pedal, and carriage is retreated, and manually to eject pattern dish is ejected.

At the back of carriage 10, breech lock 13 is hinged on the pedestal 40 of disk drive by a jointed shaft 12, breech lock 13 can rotate around jointed shaft 12 like this.Be provided with dish at the end face of breech lock 13 and eject rod 14, flexibly promote to coil D forward, thereby automatically will coil D and eject disk drive with it.Setting operation pin 11 on carriage 10, operative pin 11 relies on breech lock 13 like this, is used for locating.Operative pin 11 is along with the action that moves forward and backward of carriage 10 comes mobile breech lock 13.
In addition, have a dish spool valve opening mechanism not shown in the drawings, this mechanism is arranged on the end face of carriage 10, by the preceding hole of disk drive, is used for dish D is loaded in the loader mechanism of disk drive.
Among the figure, Reference numeral 43 expression back-moving springs are used for carriage 10 flexibly is turned back to the original position from going-back position.
Fig. 6,7A and 7B represent the artificial pushing method of magneto optical driver of the present invention.Just as shown in these figures, be provided with handle hole 20 in the precalculated position of protecgulum 15 1 sides, push pedals 18 are aimed in hole 20, and it stretches out forward from the front of carriage 10, and with the inside UNICOM of disk drive.Hole 20 is provided with can open the door 50, and door 50 is hinged on the one side in hole 20.Can open the door 50 can center on jointed shaft 21 hand-turning, and when being in the artificial pushing method of dish liftout attachment, the finger of being convenient to opening operation hole 20 and allowing the user is by hole 20, operation push pedal 18.If handle hole 20 is not provided with door 50 o'clock, then foreign matter for example dust can be penetrated into the inside of disk drive and cause the damage of disk drive by hole 20.
According to the present invention, preferably the size in selection operation hole 20 is so that user's finger can be by being as the criterion.
Can open the door 50 is hinged on the jointed shaft 21, is positioned on the inside surface on one side of hole 20, so that door 50 can rotate around jointed shaft 21.According to the present invention, the door 50 preferred synthetic resin materials that adopt, door 50 can have predetermined elasticity like this.Because the elasticity of door 50 can flexibly be rotated by counter clockwise direction around jointed shaft 21 so mean door 50, and be got back to its off-position.Therefore, if want to open the door 50 the time when not applying external force, then door 50 is maintained in its closed position always.
According to the present invention, also can giving to open the door 50 is provided with a back-moving spring in coupling place with jointed shaft 21.Like this, door 50 is because the recuperability of back-moving spring is maintained in its closed position under normal conditions.
In other words, a fastener (not shown) is installed also can for door 50, and is locked in forcibly on the protecgulum 15 by fastener.
The operating effect of above dish liftout attachment is described below:
For the dish D with Fig. 2 and Fig. 3 ejects disk drive automatically, the action button (not shown) of touch dish liftout attachment control module, signal of action button output is to solenoid 30.Solenoid 30 is driven by the signal of button.So coil 30 produces a magnetic force, and make hook stick 31 direction of arrow as shown in Figure 5 of withdrawal withdraw.Because the result of hook stick 31 withdrawal actions makes and the control lever 33 of rod 31 couplings moves in the direction of the clock around jointed shaft 32, therefore shown in Figure 4 and 5, control lever 33 retreats carriage 10.
Because the backward movement of carriage 10 makes the operative pin 11 of carriage 10 leave breech lock 13, so breech lock 13 flexibly rotates by counterclockwise centering on jointed shaft 12 shown in Fig. 4 arrow.By when counterclockwise rotating, the hook stick 14 of breech lock 13 is pushed dish to the front in the hole 42 of carriage 10 at breech lock 13.Therefore make dish D from disk drive, eject, as the dot-and-dash line of Fig. 4.
Dish D finish eject action after, the hook stick 31 of solenoid 30 is stretched over its original position, therefore, because the restoring force of back-moving spring 43, carriage 10 flexibly is returned to its original position.Because the answer of carriage 10 action, so breech lock 13 also returns to its original position, so that reaches dish load stand-by state.
As mentioned above, when automatically dish being ejected magneto optical driver, dish liftout attachment of the present invention is to adopt electric coil to cause the action of stretching out and withdrawing of hook stick 31, and does not use rotatablely moving of common high deceleration motor.Therefore this liftout attachment has been removed high high deceleration motor from.So reduced the expense of disk drive.
Secondly, owing to adopt simply stretching out and retraction movement of electric coil hook stick under the dish mode ejecting automatically.So that the dish liftout attachment has been removed movement conversion mechanism commonly used when converting rotatablely moving of high deceleration motor the rectilinear motion of carriage to from.Such dish liftout attachment had both structurally also all been simplified in operation.Owing to coil the simple structure and the simple operations of liftout attachment, thereby improved the throughput rate and the operating efficiency of disk drive.
According to dish liftout attachment of the present invention, when occurring operating in the dish liftout attachment, for example owing to have a power failure or liftout attachment when breaking down, the dish D that is loaded in the disk drive can manually eject from disk drive.For the ease of manually ejecting dish D, the door 50 among Fig. 7 A can pull to the place ahead by hand, can center on jointed shaft 21 rotary doors 50 like this, just can be as Fig. 7 B as having shown opening operation hole 20.
After opening door 50, user's finger can stretch in the hole 20, and the push pedal 18 of carriage 10 is rolled back, and carriage 10 is just manual has like this retreated.The artificial backward movement of carriage 10 also causes breech lock 13 similarly flexibly to rotate described as ejecting pattern automatically.So dish D manually is ejected disk drive manually to eject pattern.
After will coiling D and ejecting disk drive, the external force that is applied on the door 50 is removed, so door 50 flexibly is returned to its original position, the position of promptly closing again.This is because due to the elasticity of door 50 hinged parts.At this place, door 50 is hinged on the jointed shaft 21 of protecgulum 15.Like this shown in Fig. 7 A, just door has been closed handle hole 20.
Can simply dish D be ejected disk drive by hand according to dish liftout attachment of the present invention, and need not to use for example pin anchor clamps of independent instrument, so improved its usability.
Secondly, simplified on its structure owing to coil liftout attachment, so the throughput rate of disk drive has also been improved.
As mentioned above, the dish liftout attachment of magneto optical driver of the present invention is to have adopted solenoid to replace the motor that ejects commonly used, at the driving means that ejects automatically under the pattern as carriage, has to manually ejecting opening the door of dish usefulness in that the pattern that manually ejects is next.Therefore simplified the structure of disk drive and improved its usability.
Although for the purpose of illustration, disclosed above-mentioned preferred implementation of the present invention, be used for assessing various remodeling, so other adds additional and replacement all is possible, and do not break away from protection domain of the present invention and spirit.
