  • Publication number: 20210008286
    Abstract: A recording device for injection device includes a housing, a viewing window, a photographic module, a light splitting element and a signal transmission device. The housing is removably mounted on a dose scale window of an injection device. The viewing window is formed on a surface of the housing, and a viewing path is formed from the viewing window to the dose scale window. The photographic module is located on the housing, and provided with an image-capturing optical axis which is perpendicular to the viewing path. The light splitting element is located at an intersection of the viewing path and the image-capturing optical axis for guiding information located in the dose scale window to the photographic module and the viewing window, respectively. The signal transmission device is electrically connected to the photographic module for transmitting signals of the photographic module to an external device.

  • Patent number: 10705555
    Abstract: A roller module for an input module includes a roller base, a roller element and an adjusting element. The roller element is pivotally coupled to the roller base. Moreover, at least one discontinuous protrusion structure is circumferentially arranged a bottom surface of a concave region of the roller element. A contacting part of the adjusting element is contacted with the at least one discontinuous protrusion structure. Consequently, a rotation of the roller element results in a tactile feel.

  • Patent number: 10698499
    Abstract: A mouse device includes a lower casing, a circuit board, an upper casing, a button and an elastic element. The switch module is disposed on the circuit board. The circuit board is located over the lower casing. The upper casing has a slot. The upper casing and the lower casing are combined together. The button includes a push structure. The push structure includes a contacting portion corresponding to the switch module. The push structure is penetrated through the slot. The button is pivotally coupled to the upper casing. Consequently, the button is permitted to be swung relative to the upper casing. The elastic element is arranged between the contacting portion and the upper casing. Moreover, two ends of the elastic element are respectively contacted with the contacting portion and the upper casing. Consequently, the contacting portion is in contact with the switch element.

  • Publication number: 20200135415
    Abstract: A switch module includes a switch base, a common terminal, a normally open terminal, a resilient piece, an upper cover and a soft element. The resilient piece includes a first portion and a second portion. The first portion of the resilient piece is disposed on the common terminal. The second portion of the resilient piece is located over the normally open terminal. The upper cover is disposed on the switch base to cover the common terminal, the normally open terminal and the resilient piece. The soft element is arranged between the upper cover and the second portion of the resilient piece. When an external force exerted on the resilient piece is eliminated, the second portion of the resilient piece is moved in a direction away from the switch base in response to an elastic restoring force of the resilient piece.

  • Patent number: 10636593
    Abstract: A silent keyboard and a key structure are provided. The key structure includes a keycap, a buffering layer, a stabilizing element and a supporting plate. The keycap includes a bottom surface and a protrusion edge. The protrusion edge is disposed on a periphery of the bottom surface. The buffering layer is disposed on the bottom surface and the protrusion edge. The buffering layer includes a flat part, a raised part and plural coupling parts. The stabilizing element is located under the keycap and pivotally coupled to the coupling parts. The supporting plate is located under the keycap. The supporting plate includes a key seat, a supporting surface and plural recesses. The plural recesses are aligned with the corresponding coupling parts. While the keycap is moved toward the supporting plate, the flat part, the raised part or the plural coupling parts are subjected to deformation.
