摘要： In a keyboard, a keybutton opposes an operation detection portion. A light source is provided on an outer side of the operation detection portion. A light guide member guides light from the light source to a keytop of the keybutton. The light guide member includes an incident portion opposing the light source, an emitting portion opposing the keytop, and a guide portion which guides the light incident from the incident portion to the emitting portion. An incident surface of the incident portion is formed in a shape of a curved surface that protrudes to the light source side.

摘要： A capacitive keyboard that can detect a key that has been depressed and the depressed amount thereof with high accuracy is provided. The capacitive keyboard includes a drive circuit 11 that alternatively switches the voltage of each of drive lines M from an L-level to an H-level, a sensing circuit 12 that is connected to each of sensing lines N and that selects one of the sensing lines N to detect the voltage generated in the selected sensing line, and a control circuit 15. The control circuit 15 includes a storage unit 44 including storage areas corresponding to keys, a storage control unit 42 that acquires the voltage generated in the sensing line and that stores the acquired voltage in a storage area corresponding to a key, and a correction unit 43 that corrects, if one of the keys is operated, the voltage generated as a result of an operation of the one of the keys by using voltages stored in storage areas corresponding to other keys. Thus, even if a plurality of keys are depressed at the same time, detection with high accuracy can be realized.

摘要： A hardenable steel sheet is treated with press-forming by means of a die. The method is comprised of: heating the steel sheet to a temperature of an Ac3 point or higher; carrying out a primary press on the heated steel sheet so as to give a local strain to a limited part of the steel sheet; keeping the steel sheet in a state apart from the die shortly after the primary press; and carrying out a press on the steel sheet kept in the state and retain the steel sheet in close contact with the die.

摘要： A key switch including a substrate prepared from dielectric material, and first and second electrodes respectively formed on the bottom and top surfaces of the substrate to constitute a capacitor together with the substrate. The first electrode is electrically connected to a pulse voltage signal oscillator, thereby pulsatively storing a static capacitance between the first and second electrodes. A first fixed contact electrically connected to the second electrode is provided on that portion of the surface of the substrate. A second fixed contact is positioned near the first fixed contact. The first and second fixed contacts are electrically connected or shut by a manually operable movable conductive rubber contact.
