Abstract
A sheet separation member having a separation pick includes a substrate made of hard material, which is swingable around a support shaft connected to a stable member, and a wrapping member made of resin softer than the substrate for wrapping the substrate. A leading end of the substrate is integrally molded with the wrapping member using inert molding, and a leading end of the wrapping member protrudes from the leading end of the substrate by not more than 5 mm.
Claims6
A sheet separation device having a separation pick configured to separate sheets conveyed by a sheet conveyance mechanism, said separation pick comprising:
- a substrate made of hard material and swingable around a support shaft connected to a stable member;
- and
- a wrapping member made of resin softer than the substrate and configure to wrap the substrate;
- wherein a leading end of the substrate is integrally molded with the wrapping member using inert molding, and
- wherein a leading end of the wrapping member protrudes from the leading end of the substrate by not more than 5 mm.
A sheet conveyance apparatus comprising:
- a sheet conveyance mechanism configured to convey sheets;
- and
- a sheet separation device having a separation pick configured to separate sheets conveyed by a sheet conveyance mechanism, said separation pick including:
- a substrate made of hard material and swingable around a support shaft connected to a stable member;
- a wrapping member made of resin softer than the substrate and configure to wrap the substrate;
- and
- a leading end position adjusting mechanism arranged on the opposite side of the leading end of the separation pick;
- wherein a leading end of the substrate is integrally molded with the wrapping member using inert molding and the wrapping member protrudes from the leading end of the substrate by not more than 5 mm;
- wherein the leading end of the separation pick is arranged in the vicinity of a sheet passage of the sheet conveyance mechanism, and
- wherein a gap between the leading end of the separation pick and the sheet passage is adjusted by the leading end position adjusting mechanism.
An image forming system including a fixing subsystem configured to fix a toner image onto a sheet, said fixing subsystem including a sheet conveyance apparatus comprising:
- a sheet conveyance mechanism configured to convey sheets;
- and
- a sheet separation device having a separation pick configured to separate sheets conveyed by a sheet conveyance mechanism, said separation pick including:
- a substrate made of hard material and swingable around a support shaft connected to a stable member;
- a wrapping member made of resin softer than the substrate and configure to wrap the substrate;
- and
- a leading end position adjusting mechanism arranged on the opposite side of the leading end of the separation pick;
- wherein a leading end of the substrate is integrally molded with the wrapping member using inert molding and the wrapping member protrudes from the leading end of the substrate by not more than 5 mm;
- wherein the leading end of the separation pick is arranged in the vicinity of a sheet passage of the sheet conveyance mechanism, and
- wherein a gap between the leading end of the separation pick and the sheet passage is adjusted by the leading end position adjusting mechanism.
