Description
Technical field
The present invention relates to a kind of CD player adjusting gear and CD player, and be particularly related to a kind of in order to avoid guide rod because of producing CD player adjusting gear and the CD player that moment of torsion is out of shape.
Background technology
In the epoch now that development in science and technology is maked rapid progress,, make the CD that possesses high storage capacity become important software carrier in modern's daily life along with the application popularization of picture, music, film and computer software.Wherein, CD more can be divided into CD and DVD, but its capacity is big, the characteristic of the little and safe storage data of volume, more allows masses like and adopts.In addition, therefore the CD player that can read CD and DVD also becomes one of basic outfit of PC.
Because the data orbital distance of DVD is littler than the data orbital distance of CD, makes that the storage area of DVD is bigger than the storage area of CD.Therefore, CD player must read the data of DVD with the optical read/write head of less laser spot and bigger numerical aperture (NA).When CD player read optical disc data, the inclination permission of CD and the cube of numerical aperture were inversely proportional to, and the inclination permission when causing reading DVD is less.Yet, in the process of CD player manufacturing and assembling, will produce the tolerance on making and assembling.Therefore, CD player needs adjusting mechanism to adjust and reduces the degree of tilt of the optical axis of optical read/write head with respect to cd side, reads quality with the CD that improves optical read head.
The CD player with CD player adjusting gear of prior art sees the Taiwan patent announcement No. 565828, wherein, CD player comprises an optical read head and at least one CD player adjusting gear at least, optical read head is positioned on the guide rod, and the CD player adjusting gear comprises that one adjusts a screw and a shell fragment.
Owing to adjust the elastic force direction parallel opposed longer sides that locks force direction and shell fragment force section of screw, but not be located along the same line, and the point of application of two power on guide rod be separated with a distance mutually, causes guide rod will be subjected to a torsional interaction.Thus, guide rod will produce the phenomenon of distortion, and the guide rod after the distortion will seriously influence the mobile smoothness of optical read/write head.In addition, when CD player is subjected to external impacts,, cause the kink of shell fragment to be easy to generate the phenomenon of permanent strain or fracture because the bending degree of shell fragment is excessive, very big to the quality influence of CD player adjusting gear.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of CD player adjusting gear and CD player.The adjustment screw of described CD player adjusting gear and shell fragment, can be avoided guide rod because of being subjected to the phenomenon that moment of torsion produces distortion, and keep the mobile smoothness of optical read/write head the guide rod design of the application of force opposite to each other along same rectilinear direction.In addition, the design of shell fragment of the present invention is in the time of can avoiding shell fragment to be subjected to external impacts and produce the phenomenon of permanent strain or fracture.
According to purpose of the present invention, provide a kind of CD player adjusting gear.This CD player adjusting gear is arranged on the movement, in order to the distance between the movement surface of adjusting a guide rod and movement.The CD player adjusting gear comprises a shell fragment and an adjustment screw, and shell fragment comprises a junction surface and a supporting part.The junction surface is smooth on the movement surface, and the supporting part is connected with the junction surface, and forms an angle with movement surface, but the supporting part props up guide rod in the mode of springing.Adjust screw and engage with movement in the mode that runs through the supporting part, in order to the supporting part along same straight line to the guide rod application of force opposite to each other, feasible adjustment screw and supporting part clamp guide rod.Wherein, when adjusting screw and be rotated, guide rod and supporting part trend or away from the movement surface.
According to a further object of the present invention, a kind of CD player is proposed, comprise a movement, a guide rod, an optical read head and a CD player adjusting gear at least.Movement has a movement surface, and guide rod is arranged on the movement surface.Optical read head and guide rod articulate, and move along the bearing of trend of guide rod.The CD player adjusting gear is arranged on the movement, in order to adjust the distance between guide rod and the movement surface.The CD player adjusting gear comprises a shell fragment and an adjustment screw, and shell fragment comprises a junction surface and a supporting part.The junction surface is smooth on the movement surface, and the supporting part is connected with the junction surface, and forms an angle with movement surface, but the supporting part props up guide rod in the mode of springing.Adjust screw and engage with movement in the mode that runs through the supporting part, in order to the supporting part along the same adjusting to a line guide rod application of force opposite to each other, feasible adjustment screw and supporting part clamp guide rod.Wherein, when adjusting screw and be rotated, guide rod and supporting part trend or away from the movement surface, and the optical axis direction of optical read head will and then be changed.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent, a preferred embodiment cited below particularly, and conjunction with figs. are described in detail below:
