Abstract
Abstract A memory cartridge loading/unloading device is disclosed which loads and unloads a memory cartridge from an apparatus for using the memory cartridge by means of motor driving. In the loading/unloading device, until the memory cartridge reaches a given position within a main body of the apparatus, the memory cartridge is pulled in by rotating a roller which presses against the memory cartridge such that there can be produced a given friction force with respect to the memory cartridge. When the memory cartridge reaches the given position, then an engagement member is brought into engagement with the memory cartridge and then the engagement member is moved in a cartridge insertion direction by means of motor driving, so that the memory cartridge can be pushed into a connector disposed within the apparatus main body.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
158 words
A memory cartridge loading/unloading device, comprising: a roller for pressing against a memory cartridge inserted into a given position within a main body of an apparatus for using said memory cartridge in such a manner that a given frictional force is produced with respect to said memory cartridge; roller drive means for driving said roller in a cartridge insertion direction by use of a motor so that said memory cartridge is moved by said frictional force; a slide member movably disposed in a cartridge insertion/discharge direction; a claw-shaped engagement member disposed in said slide member, movable apart from said memory cartridge during the movement of said memory cartridge by said roller and engageable with said memory cartridge when said memory cartridge is moved by a given amount; and slide member drive means for driving said slide member in said cartridge insertion direction using a motor to thereby push said memory cartridge into a connector within said main body.
Claim 2
Dependent Claim
158 words
A memory cartridge loading/unloading device, comprising: a roller for pressing against a memory cartridge inserted into a given position within a main body of an apparatus for using said memory cartridge in such a manner that a given frictional force is produced with respect to said memory cartridge; roller drive means for driving said roller in a cartridge insertion direction by use of a motor so that said memory cartridge is moved by said frictional force; a slide member movably disposed in a cartridge insertion/discharge direction; a claw-shaped engagement member disposed in said slide member, movable apart from said memory cartridge during the movement of said memory cartridge by said roller and engageable with said memory cartridge when said memory cartridge is moved by a given amount; and slide member drive means for driving said slide member in said cartridge insertion direction using a motor to thereby push said memory cartridge into a connector within said main body.
Claim 3
Dependent Claim
59 words
A memory cartridge loading/unloading device as set forth in claim 1, further including a roller retreat mechanism for pushing up a rotation shaft of said roller in conjunction with the feeding operation of said slide member in said cartridge insertion direction to thereby retreat said roller from said memory cartridge so as not to press against said memory cartridge.
Claim 4
Dependent Claim
43 words
A memory cartridge loading/unloading device as set forth in claim 1 or 2, wherein said roller drive means drives said roller in a cartridge discharge direction by use of a motor to thereby move said memory cartridge by means of said frictional force.
Claim 5
Dependent Claim
104 words
A memory cartridge loading/unloading device as set forth in claim 1, wherein said slide member comprises first and second slide members respectively movable in said cartridge insertion direction and interconnected with each other through a spring, said engagement member is disposed in said first slide member such that said engagement member is freely opened and closed, and said slide member drive means moves said second slide member ion said cartridge insertion direction to thereby mount said memory cartridge to said connector within said main body by applying a given energization force through said spring, first slide member and engagement member to said memory cartridge.
Claim 6
Dependent Claim
63 words
A memory cartridge loading/unloading device as set forth in claim 4, wherein said slide member drive means includes opening/closing means for closing said engagement member in conjunction with the motor driving of said second slide member in said cartridge insertion direction and for opening said engagement member in conjunction with the motor driving of said second slide member in said cartridge discharge direction.
Claim 7
Dependent Claim
65 words
A memory cartridge loading/unloading device as set forth in claim 4 or 5, wherein said second slide member includes a discharge claw for discharging said memory cartridge mounted to said connector out of said connector, and wherein said slide member drive means moves said second slide member in said cartridge discharge direction to thereby discharge said memory cartridge from said connector through said discharge claw.
