Patent number: 5206771Abstract: A tape drive mechanism for a video tape recorder and an audio tape recorder. The tape drive mechanism automatically corrects the position of tape in the width-wise direction thereof without mechanically restricting the edge of tape. Sensors (8) and (8) on a tape path detect a dislocation of the tape (7) from a reference running position that may develop in the width-wise direction of the tape (7), a tape guide post (1) for attracting the tape (7) is moved in the width-wise direction of the tape, or inclination of a tape guide post (41) is changed to move the tape (7) in such width-wise direction by means of actuators (2), (42) and (62) that give corresponding displacement based on the values detected by the sensors (8) and (8), or the reel plate (57) is moved in the direction of width of tape to move the tape (7) together with the reel (24). The tape (7) having a small thickness is prevented against vertical movement on the tape path and is permitted to run stably without damaging the edges of the tape.Type: GrantFiled: August 30, 1990Date of Patent: April 27, 1993Assignee: Kabushiki Kaisha Sankyo Seiki SeisakushoInventors: Daiichirou Katou, Tamotsu Mitsuyasu, Kazuo Abe, Takuji Sekiguchi, Hitoshi Yanagisawa, Tsuneharu Hashizume, Toshihiko Okina, Mitsutaka Miyashita, Masaki Gotoh

Patent number: 5004898Abstract: An optical reading device which is capable of being assembled readily and assures stabilization of the distance between a sensor of the reflecting type and a surface of a medium to be read by the sensor. The sensor is carried on a holding member, and an engaging member is pivotally supported on the holding member at a location spaced from the sensor. A screw shaft and a guide shaft extend in parallel to each other and to an axis of pivotal motion of the engaging member. The screw shaft has a spiral groove formed thereon for meshing engagement with a toothed portion formed on the engaging member or the holding member and is rotated to move the holding and engaging members therealong. A record medium to be read by the sensor is fed in a direction perpendicular to the screw shaft. A contact element is provided on the holding member for assuring a minimum distance between the sensor and a surface of the record medium to be read by the sensor.Type: GrantFiled: August 9, 1989Date of Patent: April 2, 1991Assignee: Alps Electric Co., Ltd.Inventors: Hiroshi Ishikawa, Kazuo Hasegawa, Masaki Gotoh
