A keyboard instrument having a key and a link mechanism provided on a lower side of the key, and the link mechanism has a first member having a first fixing fulcrum, a first link pivotally supported on the first fixing fulcrum on one end side, a second member having a second fixing fulcrum provided further forwards and further downwards than the first fixing fulcrum, a second link pivotally supported on the second fixing fulcrum on one end side and a coupling link configured such that a distance between the other end side of the first link rotating about the first fixing fulcrum in response to a key operation and the other end side of the second link rotating about the second fixing fulcrum in response to the key operation is fixed and remains unchanged, and the second link has a counterweight provided further forwards than the second fixing fulcrum.

Keyboard instrument

A keyboard instrument has a first member having a first fixation fulcrum, a first link rotatably fixed to the first fixation fulcrum at one end side thereof, a second member having a second fixation fulcrum provided further forwards and downwards than the first fixation fulcrum, a second link rotatably fixed to the second fixation fulcrum at one end side thereof, and a coupling link fixed to a key so as to couple the other end side of the first link and the other end side of the second link together.

An electronic device having a waterproof structure includes a housing having a sound hole waterproofed by a waterproof membrane; an barometer which is arranged in the housing, determines data variable in response to a state of the waterproof membrane, and outputs the determined data; and a central controller which detects an abnormal state of the waterproof membrane based on atmospheric pressure data outputted from the barometer.

Electronic device having a waterproof structure

An electronic device including a body case which has an accommodating section at least partially in a curved shape, a frame which has a first frame section and a second frame section having a width shorter than a width of the first frame section, and is accommodated in the accommodating section, and a circuit board which is accommodated in the accommodating section so as to be laminated on the frame, and provided so as not to overlap with the second frame section when viewed from a laminated direction of the frame.

Electronic device

An electronic apparatus includes a front case, a rear case whose peripheral portion is brought into engagement with a peripheral portion of the front case and an electrostatic capacity type sensor portion which is encompassed by the front case and the rear case. A primary conductive portion, which is brought into engagement with the sensor portion for electrical connection, is formed on part of an inner surface of the peripheral portion of one of the cases which extends to the engagement portion. By adopting this configuration, the electronic apparatus can be fabricated easily and the operation of a touch switch provided in the electronic apparatus can be stabilized.

Electronic apparatus

A rental system contains a plurality of rental digital cameras, and comprises a rental-item providing machine which provides users with digital cameras, respectively, and a management center which manages the digital cameras. The rental-item providing machine makes a credit inquiry about the users. The rental-item providing machine provides the users with the respective digital cameras, in accordance with a result of the credit inquiry. The rental-item providing machine sends identification information for identifying each of the contained digital cameras, to the management center. The management center manages the digital cameras, using the identification information sent from the rental-item providing machine.
