  • Patent number: 11776511
    Abstract: Provided is a keyboard device that can suppress a reduction in the operability of a key. A rear guiding member comprises a pair of guiding surfaces that, in a side view of a key, face forward and rearward and are formed along an arc that is convex toward the front. The key comprises a pair of sliding surfaces that slide against the pair of guiding surfaces. Due to this sliding of the guiding surfaces and the sliding surfaces, rotation of the key can be guided while displacement of the key in the front-rear direction is regulated. Consequently, because forward and rearward displacement of the key during key pressing can be suppressed, a reduction in operability (feeling of touch) during pressing of the key can be suppressed.

  • Patent number: 11776512
    Abstract: Provided is a keyboard device for which the number of parts can be reduced. The present invention is provided with: hammers rotatably linked to a chassis; keys rotatably linked to the hammer thereof; guiding pins provided to the keys and extending in the widthwise direction of the keys; and a guiding groove provided to the chassis side and into which the guiding pins are inserted. The downward displacement of the front-end sides of the keys is guided by the rotation of the hammers with respect to the chassis, and the downward displacement of rear-end parts of the keys is guided by the sliding of the guiding pins with respect to the guiding groove. This eliminates the need for links to guide the displacement of the rear-end parts of the keys, thus allowing the number of parts to be reduced.

  • Patent number: 10620723
    Abstract: An input device includes a housing, an operation unit, a vibrating body, a piezoelectric element, a picker, and a signal processing unit. The operation unit is movable relative to the housing. The vibrating body has elasticity. The vibrating body includes a first end partially fixed to the housing, and a second end provided so as to be vibratable. The piezoelectric element is provided to the vibrating body. The piezoelectric element is configured to convert vibration energy of the vibrating body into electrical energy as the vibrating body vibrates. The picker flicks the vibrating body to allow the vibrating body to vibrate in conjunction with the operation unit. The signal processing unit is configured to receive power generated by the piezoelectric element to operate and transmit, through wireless communications, detection information to be generated as the operation unit moves.

  • Publication number: 20180373351
    Abstract: An input device of the present disclosure has a stationary part, an operation input part that is provided above the stationary part, and is movable with respect to the stationary part, a detector configured to detect information regarding operation of the operation input part, and an attachment part provided in the stationary part so as to project downward from a second surface of the stationary part. The attachment part has a holder and a coupler configured to couple to the stationary part. A holding force maintaining a state where the holder is attached to an object is smaller than a coupling force between the coupler and the stationary part. When a force is applied to the holder from above, the holding force of the holder allows the holder to be fixed to the object.
