Latest Patents

Koguchi's latest patents include innovative systems designed to enhance the functionality of recording and reproducing apparatuses. One of his notable inventions is a system for providing stable tape travel direction. This system incorporates a tape travel-direction switching mechanism and a tape tension regulating mechanism. The switching mechanism ensures that a pendulum gear engages with either a supply or take-up reel table when the tape's direction is switched. This occurs while the capstan motor is turned off, preventing slack in the tape. Additionally, the tape tension regulating mechanism takes up any slack before the tape travels in the reverse direction, ensuring that the tape remains taut during operation.

Another significant patent involves a tape guide system that features a rotary head drum inclined at a predetermined angle relative to the mechanical chassis of the apparatus. This design includes a guide roller that extends vertically relative to the chassis and an inclined guide post arranged along the tape path. The unique angles involved in this design are derived from specific parameters, enhancing the overall performance of the recording and reproducing apparatus.
