Abstract
In a sheet conveying apparatus, starting sound is reduced and downsizing is contrived without causing any increase in cost. The sheet conveying apparatus is provided with a plurality of pairs of rotary members disposed along a sheet conveying path for guiding a sheet, and conveying the sheet, a plurality of rotary driving devices for rotating the pairs of rotary members, and a control device for staggering the starting time of each rotary driving device and starting the rotary driving devices.
Claims15
A sheet conveying apparatus comprising:
- a plurality of pairs of rotary members, disposed along a sheet conveying path for guiding a sheet, for conveying said sheet;
- a plurality of rotary driving means for rotating said plurality of pairs of rotary members;
- and
- control means for starting said plurality of rotary driving means such that starting times of each of said plurality of rotary driving means are staggered when a power source switch of said sheet conveying apparatus is closed.
1 more element
A sheet conveying apparatus comprising:
- a plurality of conveying means provided with at least one rotary member for conveying a sheet along a sheet conveying path, and each driven by independent driving means;
- a plurality of sheet detecting means for detecting a presence of the sheet at predetermined positions of said sheet conveying path;
- and
- control means for controlling each of said driving means when a power source switch of said sheet conveying apparatus is closed so as to start said driving means such that starting times of each of said driving means are staggered, and to stop said driving means in accordance with a detection of the sheet by said plurality of sheet detecting means after a start of said driving means.
1 more element
A sheet conveying apparatus comprising:
- a plurality of conveying means provided with at least one rotary member for contacting with a sheet and being rotated to thereby convey the sheet along a sheet conveying path, and each driven by independent driving means;
- a door openable and closable to clear a sheet jammed in said sheet conveying path;
- detecting means for detecting that said door has been closed;
- a plurality of sheet detecting means for detecting a presence of the sheet at predetermined positions of said sheet conveying path;
- and
- control means for controlling each of said driving means when said detecting means detects that said door is closed so as to start said driving means such that starting times of each of said driving means are staggered, and to stop said driving means in accordance with a detection of the sheet by said plurality of sheet detecting means after a start of said driving means.
