Abstract
A keyboard is provided with a base member, moving members provided on the base member and unit parts. Each of the unit parts includes a contact which is electrically connected when depressed and an elastic member. The moving members include a first moving member which engages with one unit part, and a second moving member which engages with plural unit parts. The second moving member has a structure where the second moving member pushes the elastic member of one unit part and avoids pushing the elastic member of the other unit part.
Claims7
A keyboard comprising:
- a base member;
- elastic members;
- support parts connected to said base member;
- sliders, respectively supported by said support parts, including first sliders configured to push said elastic members, respectively, and second sliders configured to not push said elastic members;
- keytops, each connected to at least one slider moving with the at least one slider connected thereto when pushed;
- and
- an electrical connecting member, wherein
- when one of the keytops is depressed, one of the sliders connected to the depressed keytop deforms one of the elastic members and the deformed elastic member pushes the electrical connecting member to make an electrical connection,
- said keytops including a first keytop attached to one of said first sliders and none of said second sliders, and a second keytop attached to at least one of said first sliders and at least one of said second sliders, said first keytop with the respectively connected sliders and said second keytop with the respectively connected sliders are exchangeably attached to and detached from said base member.
A keyboard comprising:
- a base member;
- moving members provided on said base member, each of which moves when being pushed;
- unit parts, each including a contact which is formed in an electrical connecting member and electrically connected when depressed, an elastic member which is arranged between said moving member and said electrical connecting member, which deforms upon being pushed by said moving member and which pushes said electrical connecting member, and a support part provided on said base member that supports said moving member;
- and
- a biasing member which is arranged around said support part and which biases said moving member in a direction away from said electrical connecting member, wherein an elastic force of said biasing member is smaller than an elastic force of said elastic member;
- wherein
- said moving members include a first moving member which engages with one unit part, and a second moving member which engages with plural unit parts,
- said first moving member and said second moving member are exchangeably attached to and detached from said base member, and
- said second moving member has a structure where said second moving member pushes said elastic member of one unit part among said unit parts which are engaged with and avoids pushing said elastic member of the other unit part.
