Multiple contact input device
InactiveUS6399904B1Manual control with multiple controlled membersMultiple contacts formed in one plate/layerEngineeringElectrical and Electronics engineering
The present invention relates to a multiple contact input device which makes it possible to use a single operation member in common for the purpose of controlling a coordinate signal and setting a point thereby preventing two switches from simultaneously operating. The device reduces the number of elements of the multiple contact input device. A base is provided with a first switch and four second switches at a periphery of the first switch, and an operation member is provided with a first pressing portion, second pressing members, and projections. When the operation member is swung longitudinally and laterally, the second pressing portions press the second switches. When the operation member is swung diagonally, each projection touches a receiving portion of the base, thereby preventing the second pressing portions from pressing the second switches. When the operation member is pushed, the first pressing portion presses the first switch.

A transmissive key sheet using translucent resin, which is capable of effective illumination while ensuring the thinness of the entire key sheet as well as suppressing a decrease in light transmission, input keys using the transmissive key sheet, and electronic equipment with the input keys. A transmissive key sheet of input keys comprises a first key sheet unit and a second key sheet unit, the opposite side of the first key sheet unit from key tops and the opposite side of the second key sheet unit from pressure applicators being bonded together with a translucent adhesive. The key tops made of translucent resin are molded integral with a translucent resin film having letters on its under surface to provide the first key sheet unit. The pressure applicators made of translucent resin are molded integral with a translucent resin film to provide the second key sheet unit. The light from a light source on a substrate illuminates keys so that the letters printed on the under surface of the translucent resin film become visible form outside. The pressing of each key top presses a corresponding key switch through the pressure applicator, and the key switch is concavely curved to make a contact with an electrode on the substrate. Thus, key input is provided.
