Abstract
Embodiments provide a keyboard device having high versatility and high waterproof performance and an electronic device having the keyboard device. A keyboard device has a base plate having a plurality of attachment holes through which a plurality of hook members provided in a body chassis of an electronic device can be passed or with which the plurality of hook members can be engaged in the lower surface, a reflection sheet, which is a sheet-like member covering the lower surface of the base plate, and a plurality of keytops provided on the upper surface of the base plate, in which the reflection sheet is provided with cut lines cut in the thickness direction at positions overlapping with the attachment holes in the vertical direction.
Claims9
A keyboard device comprising:
- a base plate having a plurality of attachment holes through which a plurality of hook members in a chassis of an electronic device are configured to pass;
- a sheet-like member covering a lower surface of the base plate;
- and
- a plurality of keytops provided on an upper surface of the base plate, wherein
- the sheet-like member is provided with cut lines cut in a thickness direction at positions overlapping with the attachment holes in a vertical direction, and
- the hook members are configured to break through the sheet-like member through at least some of the cut lines, and the cut lines with the sheet-like member provide a waterproof barrier before the cut lines are broken through.
A keyboard device comprising:
- a base plate having a plurality of attachment holes through which a plurality of hook members provided in a chassis of an electronic device are configured to pass;
- a sheet-like member covering a lower surface of the base plate;
- and
- a plurality of keytops provided on an upper surface of the base plate, wherein
- the sheet-like member is provided with cut lines cut in a thickness direction at positions overlapping with the attachment holes in a vertical direction,
- the cut lines extend along a projection direction of claw portions of the hook members in attaching the hook members to the attachment holes
- the cut lines are provided in sets of two lines to one attachment hole and the two lines of each set are disposed approximately parallel to each other, and
- the two lines of each set are positionally shifted from each other with respect to the projection direction of the claw portions and a direction orthogonal to the projection direction of the claw portions.
An electronic device, comprising
- a chassis;
- and
- a keyboard device that includes
- a base plate having a plurality of attachment holes through which a plurality of hook members provided in the chassis are configured to pass;
- a sheet-like member covering a lower surface of the base plate;
- and
- a plurality of keytops provided on an upper surface of the base plate, wherein
- the sheet-like member is provided with cut lines cut in a thickness direction at positions overlapping with the attachment holes in a vertical direction;
- wherein
- the hook members break through the sheet-like member through at least some of the cut lines and are engaged with the attachment holes, whereby the keyboard device is fixed to the chassis, and
- the cut lines with the sheet-like member provide a waterproof barrier before the cut lines are broken through.
