Abstract
Abstract The present invention relates to a transfer sheet guiding device. The transfer sheet guiding device includes a separator for separating one lateral side of the transfer sheet from a photosensitive drum and a guiding plate for guiding the transfer sheet in a direction away from the photosensitive drum. The guiding plate extends in an adjustably inclined position with one lateral side thereof adjacent the separating means disposed at a level lower than the other lateral side thereof.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
182 words
A transfer sheet guiding device for separating and transporting a transfer sheet from a photosensitive drum having a central axis, said device comprising: means adjacent an end of the photosensitive drum for separating one lateral side of the transfer sheet from the photosensitive drum; transport means for transporting the transfer sheet in a transport direction away from the photosensitive drum as the lateral side is separated by said separating means; a guide member provided downstream of said transport means with respect to the transport direction of the sheet for guiding the transfer sheet as the sheet is transported by said transport means, said guide member having a surface inclined upward from one side thereof adjacent said separating means to the other side thereof with respect to a direction perpendicular to the transport direction of the sheet so that an angle of inclination is defined between said surface and the central axis of the photosensitive drum; and means for adjusting the angle of inclination at which said surface of said guide member is inclined relative to the central axis of the photosensitive drum.
Claim 2
Dependent Claim
182 words
A transfer sheet guiding device for separating and transporting a transfer sheet from a photosensitive drum having a central axis, said device comprising: means adjacent an end of the photosensitive drum for separating one lateral side of the transfer sheet from the photosensitive drum; transport means for transporting the transfer sheet in a transport direction away from the photosensitive drum as the lateral side is separated by said separating means; a guide member provided downstream of said transport means with respect to the transport direction of the sheet for guiding the transfer sheet as the sheet is transported by said transport means, said guide member having a surface inclined upward from one side thereof adjacent said separating means to the other side thereof with respect to a direction perpendicular to the transport direction of the sheet so that an angle of inclination is defined between said surface and the central axis of the photosensitive drum; and means for adjusting the angle of inclination at which said surface of said guide member is inclined relative to the central axis of the photosensitive drum.
Claim 3
Dependent Claim
60 words
A transfer sheet guiding device according to claim 1, wherein said guide member is a plate; and said adjusting means includes, a supporting means for pivotally supporting said guide member at said one side thereof adjacent said separating means, and an adjusting mechanism provided at said other side for adjusting the inclination of said guide member about said supporting means.
Claim 4
Dependent Claim
28 words
A transfer sheet guiding device according to claim 2, wherein said separating means is a separating belt which is in contact with one end of the photosensitive drum.
Claim 5
Dependent Claim
34 words
A transfer sheet guiding device according to claim 3, wherein said guide member is conductive for attracting the transfer sheet thereto, and has a resistor connected thereto through which the guide member is grounded.
Claim 6
Dependent Claim
47 words
A transfer sheet guiding device according to claim 3, and further comprising suction means provided below said guide member, and wherein said guide member has a plurality of openings extending therethrough and through which the transfer sheet is attracted to said guide member by said suction means.
Claim 7
Dependent Claim
164 words
A transfer sheet guiding device for separating and transporting a transfer sheet from a photosensitive drum having a central axis, said device comprising: means adjacent an end of the photosensitive drum for separating one lateral side of the transfer sheet from the photosensitive drum; transport means for transporting the transfer sheet in a transport direction away from the photosensitive drum as the lateral side is separated by said separating means; a guiding plate provided downstream of said transport means with respect to the transport direction of the sheet, and including a planar surface with parallel lateral sides for guiding the transfer sheet as it is transported by said transport means; supporting means for supporting said guiding plate in an inclined position at which one of said lateral sides thereof adjacent to said separating means is disposed at a level that is lower than a level at which the other lateral side thereof is disposed; and means for varying the inclination of said guiding plate.
Claim 8
Dependent Claim
164 words
A transfer sheet guiding device for separating and transporting a transfer sheet from a photosensitive drum having a central axis, said device comprising: means adjacent an end of the photosensitive drum for separating one lateral side of the transfer sheet from the photosensitive drum; transport means for transporting the transfer sheet in a transport direction away from the photosensitive drum as the lateral side is separated by said separating means; a guiding plate provided downstream of said transport means with respect to the transport direction of the sheet, and including a planar surface with parallel lateral sides for guiding the transfer sheet as it is transported by said transport means; supporting means for supporting said guiding plate in an inclined position at which one of said lateral sides thereof adjacent to said separating means is disposed at a level that is lower than a level at which the other lateral side thereof is disposed; and means for varying the inclination of said guiding plate.
Claim 9
Dependent Claim
44 words
A transfer sheet guiding device according to claim 6, wherein said supporting means pivotally supports said guiding plate, and said varying means for varying the inclination of said guiding plate comprises means for adjusting the position of said guiding plate about said supporting means.
Claim 10
Dependent Claim
57 words
A transfer sheet guiding device according to claim 7, wherein said supporting means pivotally supports said guiding plate at a position proximate to said one lateral side adjacent to said separating means, and said varying means varies the level at which the other lateral side thereof is disposed for adjusting the inclined position of said guiding plate.
Claim 11
Dependent Claim
28 words
A transfer sheet guiding device according to claim 8, wherein said separating means is a separating belt which is in contact with one end of the photosensitive drum.
Claim 12
Dependent Claim
37 words
A transfer sheet guiding device according to claim 9, wherein said guiding plate is conductive for attracting the transfer sheet to said guiding plate, and has a resistor connected thereto through which the guiding plate is grounded.
