Abstract
Abstract Facsimile transceiver of the drum scanning type wherein the writing stylus and scanning head carriage is releasibly attached to a drive belt whereby the carriage can be manually moved relative to the belt to any point along the longitudinal axis of the drum. The transceiver is further characterized by the provision of stylus retracting structure which effects disengagement of the stylus from a copy sheet when the access cover is opened for removing or installing copy paper. Stylus retraction or disabling is also accomplished when the carriage is manually moved or when the transceiver is placed in the send mode of operation.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
91 words
Transceiver apparatus comprising: a rotatable document supporting drum structure, a stylus and support carriage therefor mounted for movement along the longitudinal axis of said drum structure, drive means including an endless belt, and means for attaching said carriage to said endless belt for movement therewith and providing manual means for moving said carriage relative to said endless belt, said attaching means comprising a manually actuable lever one end of which is spring biased towards a post member whereby the belt is securely captivated between said one end and said post member.
Claim 2
Dependent Claim
91 words
Transceiver apparatus comprising: a rotatable document supporting drum structure, a stylus and support carriage therefor mounted for movement along the longitudinal axis of said drum structure, drive means including an endless belt, and means for attaching said carriage to said endless belt for movement therewith and providing manual means for moving said carriage relative to said endless belt, said attaching means comprising a manually actuable lever one end of which is spring biased towards a post member whereby the belt is securely captivated between said one end and said post member.
Claim 3
Dependent Claim
29 words
Structure as specified in claim 1 including, means associated with said manually actuable lever for effecting movement of said stylus away from said drum upon actuation of said lever.
Claim 4
Dependent Claim
22 words
Structure as specified in claim 1 wherein, said scanning device is mounted above said stylus and spaced apart from a 60* therefrom.
Claim 5
Dependent Claim
30 words
Structure as specified in claim 1 including, means cooperating with said mode selecting means for moving said stylus away from said drum structure once the apparatus is conditioned for transmitting.
Claim 6
Dependent Claim
43 words
Structure as specified in claim 4 wherein said means for moving said stylus away from said drum structure comprises lever means supported by a stationary support frame and an elongated cam member which is co-extensive with the longitudinal axis of said drum structure.
Claim 7
Dependent Claim
101 words
A facsimile transceiver comprising, housing structure, a document supporting drum structure, means for imparting rotational movement to said drum structure, a carriage having a recording pen and scanning means thereon, means for moving said carriage relative to said drum along the longitudinal axis thereof, a cover structure providing access to said drum structure for installing a copy sheet thereon and, means for effecting movement of said recording pen away from said drum structure when said cover structure is moved to an open position, said movement effecting means being ineffective when said cover structure is moved through an angle less than 70*.
Claim 8
Dependent Claim
101 words
A facsimile transceiver comprising, housing structure, a document supporting drum structure, means for imparting rotational movement to said drum structure, a carriage having a recording pen and scanning means thereon, means for moving said carriage relative to said drum along the longitudinal axis thereof, a cover structure providing access to said drum structure for installing a copy sheet thereon and, means for effecting movement of said recording pen away from said drum structure when said cover structure is moved to an open position, said movement effecting means being ineffective when said cover structure is moved through an angle less than 70*.
Claim 9
Dependent Claim
50 words
Structure as specified in claim 6 including, mode select means for conditioning said machine for either transmitting or sending, and; means operatively associated with said mode select means for effecting movement of said recording pen away from said drum structure when said machine is in the transmit mode of operation.
Claim 10
Dependent Claim
55 words
Structure as specified in claim 6 including, a drive arrangement drivingly connected to said carriage, said drive arrangement including an endless belt, and manually operative means for disconnecting said carriage from said endless belt for permitting relative movement therebetween over a portion of said belt coextensive wiTh substantially the longitudinal axis of said drum structure.
