  • Patent number: 9144836
    Abstract: A feeding device includes a fixing base. A motor is fixed to the fixing base. The motor has an output axle. A transmission axle is fixedly connected to the output axle. The feeding device further includes a feeding block having a side fixedly connected to the transmission axle. The feeding block has a feeding notch. The feeding notch is formed around the transmission axle circumferentially. Hence, once a slender material enters the rotational space of the feeding block, the motor drives the feeding block to rotate, whereas the slender material is pressed by the feeding notch of the feeding block and sent out as a result of the continuous rotation of the feeding block. Hence, the feeding device not only enables continuous material conveyance but also allows the slender material to be conveyed smoothly even when the slender material is slightly bent or deformed.

  • Patent number: 8256906
    Abstract: A sliding cover structure and an electronic apparatus are disclosed. The sliding cover structure is used for covering a lens, and includes a base, a first cover, a second cover and a swing part. The first cover slides forwards and backwards on the base, and slides between an opening position that does not cover the lens and a closing position that covers the lens. The second cover moves upwards and downwards on the base. The swing part is pivoted with the base and has a first contact end and a second contact end. The pivoting position of the swing part and the base is located between the first contact end and the second contact end so that the swing part can perform a seesaw operation. The first contact end is located below the second cover so that the first contact end drives the second cover to move upwards.

  • Patent number: 8014844
    Abstract: An electromagnetic sliding mechanism and an electronic device are provided. The sliding mechanism includes a fixing base, a sliding piece, and an elastic piece. The fixing base and the sliding piece are respectively provided with an electromagnetic element and the two electromagnetic elements correspond to each other. The sliding piece can slide between a first position and a second position with respect to the fixing base. One end of the elastic piece is pivotally connected to the fixing base, and the other end thereof is pivotally connected to the sliding piece to slide synchronously therewith. Via a repulsive magnetic force generated by electro-magnetizing the two electromagnetic elements, the sliding piece slides automatically from the first position to the second position. When the electromagnetic sliding mechanism is applied to the electronic device, two opposite casings of the electronic device can slide with respect to each other.

  • Publication number: 20100124953
    Abstract: An electronic device with a sliding and rotating cover is provided. The electronic device comprises a fixed member, a rotating member pivoted with the fixed member, an elastic member disposed between the rotating member and the fixed member, a sliding member installed at the rotating member and may slide relatively to the rotating member, a casing connected with the fixed member, and a cover connected with the sliding member. Via this arrangement, the cover slides with the sliding member. The sliding member can rotate with the rotating member by the elastic member. Thus, the cover can rotate relatively to the casing.
