Patent number: 5665946Abstract: A combined-operation type switching apparatus which is downsized and exhibits excellent operability. An operation unit is rotatably and slidably held by a housing. An operation ring is also rotatably held by the housing. The operation ring is rotated together with the operation unit only when the operation unit is pressed. A drive unit is movably supported by a shaft of the operation unit via a spring. A push switch (swell) actuated by pressing the drive unit and rotation detecting switches (projections) actuated by rotating a drive rod of the operation ring are placed inside the housing. A first pair of rotation detecting switches is actuated by rotation of the operation unit when the operation unit is not pressed. The push switch and a second pair of rotation detection switches are actuated by pressing the operation unit such that the operation unit slides along its axis toward the push switch, and then rotating the operation unit.Type: GrantFiled: October 5, 1995Date of Patent: September 9, 1997Assignees: Alps Electric Co., Ltd., Sony CorporationInventors: Akio Nishijima, Takashi Asakawa, Shuichi Matsumoto

Patent number: 5648650Abstract: An optical reading apparatus (bar code reader) including a plurality of light emitting elements, each light emitting element emitting light in different directions onto an information recording surface which has a linear recording (bar code pattern) printed thereon. A light receiving element receives reflected light from the information recording surface and generates a recording medium read signal which is transmitted to a signal processing section for converting the recording medium read signal into a display signal. The recording medium read signal is also transmitted to a regular reflection detection section. When the regular reflection detection section detects the occurrence of a regular reflection condition from the recording medium read signal, the regular reflection detection section transmits a regular reflection detection signal to a driving controlling section which controls light emission from the plurality of light emitting elements.Type: GrantFiled: August 7, 1995Date of Patent: July 15, 1997Assignee: Alps Electric Co., Ltd.Inventors: Shin Sugifune, Tsutomu Kanno, Hajime Nabeya
