<p>PURPOSE:To prevent abnormality of a cassette inserting feeling and damage of parts and to carry out the normal loading by providing an expansion part in an engaging groove of a revolving lever and providing also a spring for energizing in the direction of preventing an engaging pin from intruding into the expansion part. CONSTITUTION:The engaging groove 5a of the revolving lever 5 is provided with the expansion part 12 of a recessed shape, and the engaging pin 2 is intrudable in a 1st position where the tape cassette 3 in a cassette holding body 1 is loadable and unloadable. Then, the spring 13 is provided to energize in the direction of preventing normally the pin 2 from intruding into the expansion part 12. A tip part of an arm part 13a of the spring 13 is brought into contact with a abutting part 5b provided integrally with the lever 5, and a groove shape of the previous groove 5a before providing expansion part 12 is secured by the arm part 13a. Consequently, the pin 2 is allowed to intrude into the expansion part 12 only when the pin 2 is pressed by larger force than the energizing force of the spring 13. By this method, the normal loading can be carried out without causing any abnormality in the cassette inserting feeling and any damage of the parts.</p> |
