Abstract

Abstract An information reproduction apparatus is provided comprising: supporting means for supporting a recording medium; a drive source for moving the recording medium between an initial insertion position and a reproduction position by driving said supporting means; transmission means incorporating a transmission element for transmitting the driving force of said drive source to said supporting means; characterised by retraction means operable to disengage said transmission element from said transmission means; and motion means operable to drive the recording medium from the reproduction position to the initial insertion position when said transmission element is disengaged, whereby said recording medium may be removed in the event of failure of said drive source.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 122 words
An information reproduction apparatus comprising: supporting means (100) for supporting a recording medium (200); a drive source (300) for moving the recording medium between an initial insertion position and a reproduction position by driving said supporting means (100); transmission means (400) incorporating a transmission element (330) for transmitting the driving force of said drive source (300) to said supporting means (100); characterized by retraction means (500) operable to disengage said transmission element (330) from said transmission means (400); and motion means operable to drive the recording medium (200) from the reproduction position to the initial insertion position when said transmission element (330) is disengaged, whereby said recording medium (200) may be removed in the event of failure of said drive source (300).
Claim 2
Dependent Claim 32 words
Apparatus as claimed in Claim 1, wherein said transmission means (400) includes a series of gears, and said transmission element (330) is a gear which is retractable from said series of gears.
