Abstract
Abstract A housing has a cover which is pivotable between an open and a closed position. A lock is movable to and from a locking mode in which it locks the cover in the closed position thereof. A cassette is carried by the cover for movement with the same and includes a take-up hub which is turnable to take up a stripshaped record carrier that is stored in the cassette. Recording electrodes are provided in the housing for recording information on the carrier, and a drive is provided for rotating the hub. A motion-transmitting arrangement is coupled with the lock and serves to shift the cassette to an operating position in which the hub is rotated by the drive and in which the electrodes record on the carrier, in automatic response to movement of the lock to its locking position.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
139 words
A recording device, particularly for the electrographic recording of measured values on a strip-shaped record carrier stored in a cassette having a take-up hub, comprising a housing; a cover mounted on said housing for movement with respect thereto between an open end and a closed position; means in said cover for receiving the respective cassette for movement with respect to said cover between a loosely inserted and an operative position; means for recording information on the record carrier when said cassette is in said operative position; and means operative when said cover is in said closed position for latching said cover in said closed position and for simultaneously moving said cassette relative to said cover into said operative position and into recording contact with said recording means while engaging said driving means with said take-up hub of said cassette.
Claim 2
Dependent Claim
139 words
A recording device, particularly for the electrographic recording of measured values on a strip-shaped record carrier stored in a cassette having a take-up hub, comprising a housing; a cover mounted on said housing for movement with respect thereto between an open end and a closed position; means in said cover for receiving the respective cassette for movement with respect to said cover between a loosely inserted and an operative position; means for recording information on the record carrier when said cassette is in said operative position; and means operative when said cover is in said closed position for latching said cover in said closed position and for simultaneously moving said cassette relative to said cover into said operative position and into recording contact with said recording means while engaging said driving means with said take-up hub of said cassette.
Claim 3
Dependent Claim
23 words
A recording device as defined in claim 1 wherein said cover is at least in part transparent for permitting viewing of said cassette.
Claim 4
Dependent Claim
16 words
A recording device as defined in claim 1, wherein said latching means comprises a key lock.
Claim 5
Dependent Claim
52 words
A recording device as defined in claim 1 wherein said driving means comprises a drive shaft and a sleeve surrounding said drive shaft and axially slidable thereon between a disengaged first position and an engaged motion-transmitting second position; and wherein said latching means effects sliding of said sleeve between said positions thereof.
Claim 6
Dependent Claim
23 words
A recording device as defined in claim 4, wherein said latching means comprises a motion-transmitting member having an arm which engages said sleeve.
Claim 7
Dependent Claim
21 words
A recording device as defined in claim 1 wherein said receiving means includes a pocket dimensioned for removably accommodating said cassette.
Claim 8
Dependent Claim
30 words
A recording device as defined in claim 6, wherein said cover is provided with an opening communicating with said pocket for permitting access of said recording means to said carrier.
Claim 9
Dependent Claim
31 words
A recording device as defined in claim 1 and further comprising biasing means resiliently biasing said cover to said open position and opposing shifting of said cassette to said operating position.
Claim 10
Dependent Claim
16 words
A recording device as defined in claim 8, wherein said biasing means comprises a biasing spring.
Claim 11
Dependent Claim
28 words
A recording device as defined in claim 1; and further comprising mounting means mounting said cover on said housing for hinged movement between said open and closed positions.
Claim 12
Dependent Claim
191 words
A recording device, particularly for the electrographic recording of measured values on a strip-shaped record carrier stored in a cassette having a take-up hub, comprising a housing; a cover mounted on said housing for movement with respect thereto in a path between an open and a closed position; means in said cover for receiving the respective cassette to share the movement of said cover in said path and also for movement with respect to said cover between a loosely inserted and an operative position; means in said housing for recording information on the record carrier when said cassette is in said operative position; means mounted in said housing for displacement substantially normal to said path between a retracted and an extended position and operative for engaging and driving the take-up hub when in said extended positioN; and means operative when said cover is in said closed position for latching said cover in said closed position and for simultaneously moving said cassette relative to said cover into said operative position and also into alignment with said driving means while displacing the latter into driving engagement with said take-up hub of said cassette.
