摘要:
In a portable communication apparatus of the invention, an inner wall (22) of an openable/closable member (2) faces the front face of a diaphragm of a close-talking microphone (5) via a sound path (64), and an outer sound hole (27) faces the rear face of the diaphragm of the close-talking microphone (5) via a sound path (65). An inner sound hole (26) is biasedly located in a position which is close to a free end of the openable/closable member (2), and the outer sound hole (27) is biasedly located in a position which is close to the center position of opening and closing movements of the openable/closable member (2), thereby obtaining a speech quality of a very high S/N ratio at a substantially same degree in both the cases where the openable/closable member (2) is opened, and where the member is closed.

A mounting member 72 is formed which is pushed by a base plate 3 on the side from which a rotation shaft of the motor main body projects, that is to say, on the side on which the counter weight is mounted. A mounting member 81 is provided which is pushed by the base plate on the bracket 80 mounted on the other face opposite to that from which the rotation shaft of the motor main body projects. A supply terminal 90 having a spring characteristic and which is mounted on the bracket and a terminal 31 which supplies electricity are pressed together. A peaked section 71 is formed in the flexible holder mounted on the outer periphery of the motor main body so that the supply terminal is tightly held against the supply terminal.
摘要:
A lighted switch illuminator which solves a problem of a conventional device in that it was difficult to reduce its thickness and size because the electroluminescent (EL) layer functioning as an illuminator is adhered to a separate film click board. An EL layer is directly formed on a film click board by stacking its layers (consisting of a transparent electrode layer, a light emitting layer, a dielectric layer, a rear electrode layer and an insulation layer) in order excluding hollow convex portions of the film click board. Upper contacts and lower contacts are formed on the film click board and a printed board, respectively, such that they face each other. Depressing a key button pushes the corresponding hollow convex portion so that the upper contact and the corresponding lower contact are brought into conduction, in which case a good clicking feeling is obtained because the EL layer is not formed on the back of the hollow convex portions. Since the film click board is an integral part of the electroluminescent light, the thickness of the illuminator can be reduced.

A click plate (9) constituting a switch used for an operation key etc. of a portable telephone is attached on a substrate (1 by soldering it on a contact pattern (6) formed on the substrate. The click plate (9) includes a convex portion (11) which center portion is expanded and made hollow. The convex portion is pushed and deformed to contact with a contact pattern (7) on the substrate thereby to generate a contact signal. The peripheral portion (10) of the click plate (9) is provided with attachment portions (17) protruded outward. The attachment portions (17) are soldered on the contact pattern (6). In this manner, the click plate can be attached on an arbitrary position in a manner that the click plate (9) is attached on the substrate (1) by the soldering.

Stress exerted on a liquid crystal display element via a case was likely to impede display on the liquid crystal display element, or damage a liquid crystal display device. A front end of a rib 9 protruding toward a case 1 from a peripheral edge portion of a holder 8 supporting a liquid crystal display element 4 is brought into contact with the case 1, whereby stress on the case 1 is imposed on the rib 9. Thus, stress directly acting on the liquid crystal display element 4 via a rubber sheet 7 can be prevented.

A push button switch of the invention has base rubber having actuator portions, a resin molded portion attached to the base rubber, and a permeable film formed on the surface of the resin molded portion. More preferably, a flange portion of the film is disposed so as to avoid a region just above thick portions such as base plate supported portions of the base rubber. A push button switch capable of preventing peeling of coating or the like and intrusion of water can be therefore provided. A push button switch and a switching device which have satisfactory touch and can be thinned can be provided.
摘要:
An illuminated button including a key button and an electroluminescent light (EL) for illuminating the key button from its bottom. The key button is composed of a silicone rubber material mixed with white color particles which prevent, while the EL is inoperative, a pink light reflected from the EL from being projected to the outside through the key button. This makes possible to solve a problem of a conventional illuminated button, which includes a key button and a white light EL used as a backlight, in that the pink color of the EL is seen from the outside through the key button, and this spoils the beauty of the illuminated button.
摘要:
A portable radio device in which a radio telephone device body and a receiver unit are separately constructed and connected together by a pair of adjustable supporting rods. As a result, the distance between the radio telephone device body and the receiver unit can be adjusted according to whether the device is being used as a telephone unit or a pager unit. While being used as a telephone, the distance between a receiver and a microphone can be easily adjusted to the distance between an ear and a mouth of a user. When the device is used as a paper, it can be miniaturized so as to be conveniently carried.
摘要:
A housing for a portable radio telephone device to which a part thereof is exposed externally at a position recessed from an outer surface of a portable radio telephone device so that the part does not contact the skin whereby heat generated within the portable radio telephone device is efficiently radiated outside and a reliable operability is provided without the outersurface portions to thereof become too hot or cold to comfortably hold by hand.
