Description of the Invention: [Technical Field] The invention relates to an electronic device', and more particularly to an electronic device in which a cover body is rotatable relative to a body. [Prior Art] A disc player generally refers to a device that reads information such as a text 'sound' image stored on a disc by optical means. The device can be connected to a computer or a television by a signal line to make text, images, etc. The information is displayed on the computer display or on the TV screen, or the machine delivers the sound to the human ear. When the disc player reads the information stored on the disc, the disc is placed in a disc valley, and the disc player can also be called a disc change device. When the disc player stops reading the disc, the disc is taken out from the accommodating area. The prior art disk changing device can be classified into a tray carrying type, a suction type changing device, or a flip type disk changing device. Among them, the tray-loading type is mainly applied to the disc drive (such as (3)-dirty, CD-R/RW, DVD_R〇M, etc.) or the home desktop audio/video player. The m-type (four) structure is mainly applied to the car-mounted disc player, and now some The home audio and video player produced by the manufacturer also adopts a slot-loading type. The tray-loading and suction-type disc changing structure is characterized in that a frame-like slit-in and out passage is provided on the main body of the disc player to facilitate the entry and exit of the tray carrying device and the optical disc. The clamshell type disc changer is mainly applied to a disc player such as a mini type, a mobile type or a portable type. Among them, the disc type disc player can be classified into two types: a display screen and a display screen. Among them, a disc player without a display screen can be set separately or without a disc cover, and a disc player with a display of 200928137 needs to be additionally provided with a disc cover to prevent the disc from flying out during use. • The current clamshell disc changer generally includes a body, a disc cover pivotally attached to the body, a locking mechanism for locking the disc cover to the body, and a torsion spring abutting the body and the disc cover. If it is necessary to close the disc cover, apply an external force to press the disc cover until the disc cover is engaged with the locking mechanism to lock the disc cover. At this time, the disc cover is closed, and the torsion spring is pressed by the cover body and the body to be in an elastic deformation state. If you need to open the disc cover, operate the closing disc cover. The locking mechanism will open the cover. At this time, the torsion spring will return to elastic deformation and generate elastic force. The disc cover will open relative to the body under the elastic force of the torsion spring. The tray-loading and suction-type disc changer structures are easily caught by foreign objects during use, thereby damaging the optical disc or the disc player itself, and the clamshell disc changer solves the above drawbacks. However, the disc cover of the above-described clamshell type disc changing device is opened relative to the body by the elastic force of the torsion spring, and the disc cover may be shaken during the opening process due to the large elastic force, thereby easily damaging the disc cover. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide an electronic device which can improve the stability during opening of a cover. The alpha electronic device includes a body, a stopper on the body, and a cover body and a torsion magazine pivoted on one side of the body, the body is provided with a through hole, and the cover body is disposed adjacent to an end of the body a first blocking member abutting the body and the cover body, the first blocking member penetrating the through hole and contacting the stopper when the cover body rotates relative to the body at 7 200928137 and generating frictional resistance The cover rotates relative to the body. The friction generated by the contact of the first blocking member with the stopper in the electronic device can prevent the cover from rotating relative to the body to stabilize the cover.

The retaining portions 242 are respectively located at two sides of the first supporting portion 224, and are respectively provided with cylindrical receiving grooves (not shown). The two positioning portions 244 respectively include two fixed 10-position columns. The two through holes 26 are adjacent to the two accommodating portions 242, respectively. The stopper 30 is located in the body 2, which may be a separate device, and is fixed on the second surface 24 of the upper casing or the lower casing 1 by conventional fixing methods such as riveting, screwing, or the like. The other components are integrated directly on the second surface 24 of the upper body 2〇 or on the lower casing 1〇. The present invention is an independent device that is fixed to the second surface of the upper casing 2, and includes an L-shaped base portion 31 and extends vertically from the base portion 31 in a direction away from the second surface 24. A stop portion 32 is formed. The two ends of the base portion 31 are provided with 8 200928137 first mounting holes 312 and second mounting holes 314 corresponding to the two positioning posts of the first positioning member 244. The screw 30 is screwed through the first mounting hole 312 and the second mounting hole 314 to the two positioning posts of the first positioning portion 244 to fix the stopper 30 to the second surface 24 of the upper casing 20. The stop portion 32 includes a first stop plate 322 and a second stop plate 324 that are parallel to each other. The cover 40 is pivotally connected to one side of the upper casing 20. The utility model is a nearly square structure. The inner surface opposite to the upper casing 20 is provided with two rotating members 42 and the first supporting portion 224 is provided with a second support. Part 48. The two rotating members 42 are respectively located at two ends of the boundary between the cover 40 and the body 15, and respectively include a fan-shaped main body portion 422 that is in contact with the inner surface of the cover body 40, and a first blocking member 424 formed by the body portion 422 extending integrally. a second blocking member 426 and a cylindrical pivot 428. The first blocking member 424 is a columnar body extending from the main body portion 422 toward the stopper portion 32, which is parallel to the stopper portion 32. The second blocking member 426 is a columnar body that is vertically connected to the first blocking member 424. The yoke shaft 428 is located at the center of the body portion 422 and is parallel to the second blocking member 426. The second supporting portion 48 is located between the two rotating members 42 and includes a first sidewall 482 and a second sidewall 484 and a third sidewall 486 extending from the first sidewall 482. Parallel to the boundary edge of the cover 40 and the body 15. The torsion spring 50 includes an elastic winding 52 that extends integrally from both ends of the elastic winding 52 to form a second force applying arm 54. The second force applying arms 54 are in contact with the first support portion 224 and the second support portion 48, respectively. The first support portion 224 and the second support portion 48 provide support for the elastic deformation of the torsion spring 50. In the assembly, the two stoppers 30 are first fixed to the second surface 24 of the upper casing 20, and the lower casing 10 and the upper casing 20 are correspondingly engaged to form the body 15. Then, the two rotating members 42 of the cover 40 are respectively passed through the two through holes 26 9 200928137 and moved to the two accommodating portions 242 until the two pivots 428 are respectively received in the receiving slots of the second portion 242. The body 40 is pivotally connected to the body 15, and the cover t 40 is rotatable relative to the body 15. Finally, the torsion magazine 50 is fixed between the first support portion 224 and the second support portion 48, so that the two force applying arms 54 abut against the first support portion 224 and the second support portion 48, respectively, and the electronic device 99 is assembled. As shown in FIG. 4 and FIG. 5, after the electronic device 99 is assembled, the cover 40 is in an open state. If the cover 40 needs to be closed, an external force is applied to press the cover 40 until the cover 40 and the cover 40 are locked. The combination is such that the cover 40 is locked. At this time, the two urging arms 54 of the torsion spring 50 are pressed by the first support portion 224 and the second support portion 48 in an elastically deformed state. If the cover 40 needs to be opened, the relevant locking device for operating the cover 50 causes the cover 50 to be in an openable state. At this time, the torsion spring 50 will return to elastic deformation to generate an elastic force, and the cover 40 can be elastically applied by the torsion spring 50. When the body 15 rotates, the two rotating members 42 are rotatable relative to the stopping member 30. When the cover 40 is rotated to a certain angle, the first blocking member 424 of the rotating member 42 is located at the first and second blocking plates 322, 324 of the blocking portion 32. The first and second blocking plates 322, 324 are in contact with each other. The friction between the blocking member 424 and the first and second blocking plates 322, 324 prevents the cover 40 from rotating relative to the body 15, thereby rotating the cover 40 smoothly. When the first blocking member 424 abuts against the base portion 31 or the second blocking member 426 abuts the second surface 24 of the upper casing 20, the force between the first blocking member 424 and the base portion 31 and the second blocking member The force between 426 and the second surface 24 of the upper casing 20 can prevent the cover 40 from rotating relative to the body 15, at which time the cover 40 is opened.
