Abstract

Abstract A magnetic tape cartridge removing apparatus in a tape player for playing a vertical stack of cartridges from the lowermost to the uppermost in succession in a bottomless enclosure, comprises a player cabinet, a platform which is provided within the cabinet and on which the lowermost cartridge rests, a movable deck resting on the platform for playing the cartridge in the play position, said movable deck mounting thereon a capstan and magnetic head or the like, deck driving means for reciprocally moving the deck between such positions of engagement with and disengagement from the cartridge in the play position, and a pushing member operable to depressedly move the cartridge in the play position from the play position during the time that the deck is reciprocally moved by deck driving means.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 384 words
In a magnetic tape cartridge player utilizing a plurality of endless magnetic tape cartridges for playing a vertical stack of a plurality of tape cartridge from the lowermost to the uppermost in succession, a magnetic tape cartridge removing apparatus comprising a player cabinet; a horizontal platform which is provided in the player cabinet and on which the lowermost cartridge rests; a movable deck on the platform; a rotatable capstan on the deck, said capstan being adapted to forcedly abut against a pinch roller in the lowermost cartridge held in the play position; deck driving means for reciprocally moving the deck between a reproducing position where the capstan engages the cartridge in the play position and a retracted position where the capstan is disengaged from the cartridge in the play position; an idler wheel mounted on said deck in opposition to the capstan, means for abutting said idler wheel against the capstan to be rotated by the capstan during the period when the deck is moving between said reproducing and retracted positions; a drum operable to be rotatable in response to rotation of the idler wheel; a pushing lever slidably mounted on the platform for reciprocal movement toward and away from said cartridge in the play position, said pushing lever having a head member to oppose a cartridge in the play position; bias means for normally urging the pushing lever to an original position where the head member of the pushing lever is away from the cartridge in the play position; a belt connecting the drum to the pushing lever, said drum being operable to take-up the belt while being rotated in response to rotation of said idler wheel; and drum means for allowing the belt to be unwound when the rotation of said drum is arrested, the pushing lever being moved into engagement with said cartridge in the play position to thereby move said cartridge away from the play position a sufficient distance to enable another cartridge to replace it as the pushing lever is moved against the bias of the bias means in response to take-up of said belt on said drum, the pushing lever being returned to the original position by the bias of the bias means and said belt being thereby unwound in response to arrest of rotation of the drum.
Claim 2
Dependent Claim 384 words
In a magnetic tape cartridge player utilizing a plurality of endless magnetic tape cartridges for playing a vertical stack of a plurality of tape cartridge from the lowermost to the uppermost in succession, a magnetic tape cartridge removing apparatus comprising a player cabinet; a horizontal platform which is provided in the player cabinet and on which the lowermost cartridge rests; a movable deck on the platform; a rotatable capstan on the deck, said capstan being adapted to forcedly abut against a pinch roller in the lowermost cartridge held in the play position; deck driving means for reciprocally moving the deck between a reproducing position where the capstan engages the cartridge in the play position and a retracted position where the capstan is disengaged from the cartridge in the play position; an idler wheel mounted on said deck in opposition to the capstan, means for abutting said idler wheel against the capstan to be rotated by the capstan during the period when the deck is moving between said reproducing and retracted positions; a drum operable to be rotatable in response to rotation of the idler wheel; a pushing lever slidably mounted on the platform for reciprocal movement toward and away from said cartridge in the play position, said pushing lever having a head member to oppose a cartridge in the play position; bias means for normally urging the pushing lever to an original position where the head member of the pushing lever is away from the cartridge in the play position; a belt connecting the drum to the pushing lever, said drum being operable to take-up the belt while being rotated in response to rotation of said idler wheel; and drum means for allowing the belt to be unwound when the rotation of said drum is arrested, the pushing lever being moved into engagement with said cartridge in the play position to thereby move said cartridge away from the play position a sufficient distance to enable another cartridge to replace it as the pushing lever is moved against the bias of the bias means in response to take-up of said belt on said drum, the pushing lever being returned to the original position by the bias of the bias means and said belt being thereby unwound in response to arrest of rotation of the drum.
Claim 3
Dependent Claim 165 words
A magnetic tape cartriDge removing apparatus in accordance with claim 1, wherein said drum is rotatably mounted on a shaft operable to be rotated in response to rotation of said idler wheel, a rotary member mounted on said shaft coaxially with and spaced from the drums said drum means including a latch lever pivotally mounted on the drum, the latch lever being normally biased by a spring to have a latch lever first end engage the rotary member, the latch lever having a second end positioned adjacent the periphery of the drum, the latch lever being operable to be pivoted by the belt taken up by the drum, rotation of the drum associated with rotation of the idler wheel being arrested when the latch lever first end is disengaged from the rotary member upon pivoting of said latch lever, the pushing lever being freely rotated with respect to the shaft when it is returned to said original position by the bias of said bias means.
Claim 4
Dependent Claim 33 words
A magnetic tape cartridge removing apparatus in accordance with claim 2, wherein said abutting means includes bias means for normally urging said deck in the direction of the cartridge in the play position.
Claim 5
Dependent Claim 34 words
A magnetic tape cartridge removing apparatus in accordance with claim 1, wherein said cabinet has an opening, the cartridge which is pressed by the pushing member being discharged by the opening from the cabinet.
