<p>PURPOSE:To load and unload simply and smoothly a cassette tape even with a portable microminiature tape recorder whose external size can be expanded/contracted, by securing the opening/closing of a cassette holder with a single hand operation. CONSTITUTION:When an open button 7 is slided toward an arrow head A and a lock part 7a is released from an engagement part 6d of a mechanism substrate 6, an engagement part 2f of the 2nd housing 2 is disengaged from a projected part 1a of the 1st housing 1. Then the housing 2 is turned by a subcase open spring 12. Under such conditions, a cassette tape 17 is inserted from the side of an arrow head B and the housing 2 is closed toward an arrow head C. Thus a shaft 15 of a link arm 13 moves toward an arrow head D. When the cassette tape 17 is loaded, the force is applied to the housing 2 from the side of an arrow head E by a toggle spring 16. Thus the tape 17 is held. In such a way, the housing 2 can be opened simply by a single hand just by operating the button 7. Furthermore the tape 17 can be held assuredly by a toggle mechanism.</p> |
