Abstract

A control mechanism for a clamper guider in a slot-in drive comprises a motor used to drive a transmission sheet to move through a gear train; the transmission sheet drives a control sheet to rotate counterclockwise or clockwise and further to cause a raised piece of the control sheet to prop against or separate from the lower end of a downward bended section of the clamper guider to allow a clamper at the lower section of the clamper guider to be separated from or entered the location that a disc is clamped. Whereby, the whole control mechanism has a more power saving structure and the matching design of the whole transmission structure and the motor used therein is more convenient.

Claims

1. A control mechanism for a clamper guider in a slot-in drive, comprising a control sheet connected at the upper side of a ceiling plate on a chassis;

an arm being extended from the side of said control sheet and three guide slots being symmetrically disposed at a same circumference;

a guide pin is combined with said arm and said guide pin being passed through a guide slot in a transmission sheet;

said transmission sheet being movably on the upper side of said ceiling plate;

three guide pins being connected at a location at the upper side of said ceiling plate relative to said three guide slots in said control sheet and said guide pins being passed through and out of said guide slots to combine each with a C-ring;

a clamper being combined with a lower section extended downward from the front end of a clamper guider and the rear end of said clamper guider being connected pivotally to said ceiling plate;

a spring for providing said clamper with a downward suppressing force being installed between said clamper guider and said ceiling plate;

holes are respectively disposed in locations of said ceiling plate and said control sheet relative to said clamper;

a raised piece projected upward and relative the side of said clamper guider being installed on said control sheet and a slant face being formed at one side of said raised piece faced to said base;

a motor and transmission gear train being combined with said chassis;

whereby, said transmission sheet is driven to move by said motor through said transmission gear train and said control sheet being driven by said transmission to take said three guide pins as supporting point to be rotated counterclockwise or clockwise so as to allow said raised piece of said control sheet to prop against or separate from the lower end of said clamper guider to control said clamper to separate from or enter the location that a disc is clamped.

2. The control mechanism according to claim 1, wherein a downward bended section bended downward is disposed at a location at said clamper guider close to said hole, a groove bended downward is disposed at a location that said control sheet contacted with said downward bended section;

whereby, the lower section of said clamper guider connected to said clamper is allowed to stretch into the lower side of said hole;

a hollow area is existed in said ceiling plate relative to the moving area of said groove.

3. The control mechanism according to claim 1, wherein said raised piece is formed as a hemisphere shape.

4. The control mechanism according to claim 1, wherein the upper side of said ceiling plate is connected movably with a first transmission sheet and connected pivotally to one end of a third sheet body;

another end of said third sheet body is connected to a guide pin, said guide pin is passed through said transmission sheet, a guide slot corresponding to said first transmission sheet and said ceiling plate.

5. The control mechanism according to claim 1, wherein a round hole is disposed in the middle of said lower section, bayonets on a neck portion projected upward and disposed in the middle of said clamper is passed through said round hole to buckle corresponding buckling holes in a buckling sheet;

whereby, said neck portion of said clamper is caused to connect pivotally to said round hole.

6. The control mechanism according to claim 1, wherein retaining sheet is extended upward from said ceiling plate;

one end of said retaining sheet is stretched into said hole and extended to the upper side of said clamper.

7. The control mechanism according to claim 2, wherein an upward bended sheet is projected out of a location at said downward bended section contacted with said raised piece.

8. The control mechanism according to claim 4, wherein said guide slots in said ceiling plate of said chassis relative to said first transmission sheet and said guide slot of said transmission sheet are respectively combined with guide pins passed through the corresponding guide slot.

9. The control mechanism according to claim 8, wherein a driving shaft of said motor is combined with a gear in said transmission gear train;

a rack is disposed at one side of said first transmission sheet so as to engage with another gear in said gear train.
