Pinch roller assembly of a magnetic recording/reproducing apparatus

Abstract

A pinch roller assembly for a magnetic recording and reproducing apparatus has a pinch roller configured to selectively contact a capstan axis mounted on a deck base. A pinch arm is provided for rotatably supporting the pinch roller on one end thereof. The pinch arm is pivotally mounted on the deck base for movement between first position and second positions. When in first position, the pinch roller is adjacent to the capstan axis, and when in the second position the pinch roller is spaced away from the capstan axis. A pinch axis is mounted on the other end of the pinch arm. The pinch axis is a pivot point of the pinch arm. A pinch spring is disposed on the pinch axis to elastically support the pinch arm when being pivoted to the first position toward the capstan axis. A separation preventing protrusion is integrally formed with the pinch axis to prevent deviation of the pinch spring.

1 . A pinch roller assembly for a magnetic recording and reproducing apparatus comprising: 
 a pinch roller configured to selectively contact a capstan axis arranged on a deck base;    a pinch arm for rotatably supporting the pinch roller on one end thereof, the pinch arm being pivotally mounted on the deck base for movement between a first position and a second position, wherein when in the first position the pinch roller is adjacent to the capstan axis and when in the second position the pinch roller is spaced away from the capstan axis;    a pinch axis mounted on the other end of the pinch arm, the pinch axis being a pivot point of the pinch arm;    a pinch spring disposed on the pinch axis to elastically support the pinch arm when being pivoted to the first position toward the capstan axis; and    a separation preventing protrusion integrally formed on the pinch axis to prevent deviation of the pinch spring.    
   
   
       2 . The pinch roller assembly of  claim 1 , wherein one separation preventing protrusion is provided to fit in a groove of the pinch spring.  
   
   
       3 . The pinch roller assembly of  claim 1 , wherein a pair of separation preventing protrusions are formed to respectively fit in grooves of the pinch spring.  
   
   
       4 . The pinch roller assembly of  claim 1 , wherein one separation preventing protrusion supports a lower part of the pinch spring.  
   
   
       5 . The pinch roller assembly of  claim 1 , wherein the separation preventing protrusion is substantially annular.
