Title: The Innovative Contributions of Roger N. Tregear
Introduction
Roger N. Tregear is a notable inventor based in San Jose, California. He has made significant contributions to the field of audio technology, particularly with his innovative designs for tape cassettes. His work has led to advancements that enhance the functionality and durability of these devices.
Latest Patents
Tregear holds a patent for an improved Philips-type tape cassette. This design features a shiftable tab that selectively blocks the opening created by the removal of the conventional knock-out tab. This improvement allows users to determine the presence of pre-recorded material on the tape. The cassette's two shells incorporate an enhanced tongue and groove structure, which ensures a secure fit and prevents relative movement. Additionally, the design includes relatively wide front and rear end walls that provide increased thickness to maintain structural integrity. An improved internal lock is strategically placed near the central part of the rear wall, where an attachment screw would be impractical. Each hub of the cassette features a leader-holding insert that supports the tape across a recess, preventing 'spoking' in the tape pack. Furthermore, the design includes improved idler posts that provide spaced cylindrical bearing surfaces while accommodating lubricant. Tape guides are positioned near the open, tape-exposing extremity to minimize the 'barber pole' effect on the tape.
