Claims
- 1. A sheet sorting apparatus comprising:
- plural bin trays arranged in vertical alignment, said trays including a front end for receiving said sheets;
- followers associated with the front ends of said bin trays;
- front end support means for supporting the front ends of said plural bin trays for vertical movement; and
- a cam member formed with a spiral grove for guiding said bin trays, said groove having an end portion of less inclination relative to a horizontal plane than he inclination of the remainder of said groove.
- 2. A sheet sorting apparatus according to claim 1, wherein one of sad followers, when lifted-up to the starting position on said less-inclined end portion, contacts another of said followers located adjacently thereabove, and thereafter ascends while pushing up said adjacent follower.
- 3. A sheet sorting apparatus according to claim 2, wherein said front end support means ascends together with the remaining followers in synchronism during the lifting-up of said followers.
- 4. A sheet sorting apparatus according to claim 1, wherein said spiral cam means comprises a pick-up portion positioned at substantially the same height as the lowermost portion of the follower which stands by at a starting position, said pick-up portion guiding said follower to the spiral groove upon revolution of said spiral cam means.
- 5. A sheet sorting apparatus according to claim 1, wherein said spiral cam means comprises upper and lower planar surfaces, and said spiral am means stops at a position where said upper and lower planar surface oppose the followers.
- 6. A sheet sorting apparatus comprising:
- plural bin trays arranged in vertical alignment, said bin trays including a front end for receiving the sheets;
- front end support means for supporting the front ends of said plural bin trays for vertical movement;
- means for moving the respective front ends of said bin trays to enlarge the opening between successive trays; and
- resilient means engaged at one end thereof with the uppermost bin tray and engaged at the other end thereof with the lowermost bin tray, and urging said bin trays toward one another, whereby when a respective bin tray is moved to enlarge the opening between successive bin trays, the remaining bin trays are moved in the same direction by said resilient means.
- 7. A sheet sorting apparatus according to claim 6, further including rear end support means for supporting the rear ends of said plural bin trays.
- 8. A sheet sorting apparatus according to claim 7, wherein means are provided for moving said rear end support means vertically relative to said front end support means.
- 9. A sheet sorting apparatus according to claim 8, wherein said respective means for moving sad front ends of said bin trays include a cam member formed with a spiral groove for guiding said bin trays, said groove having an end portion of less inclination relative to a horizontal plane than the inclination of the remainder of said groove.
- 10. A sheet sorting apparatus, comprising:
- plural bin trays arranged in vertical alignment;
- front end support frame for supporting the front ends of said plural bin trays, said frame movable by ascending and descending; and
- plural followers associated with the front ends of said bin trays and movable by ascending and descending in relation to said front end support frame;
- a follower provided uppermost with respect to said plural followers and secured to said front end support frame;
- rotating means for moving said plural followers of respective said bin rays vertically by engaging therewith to enlarge the opening between successive trays; and
- stopper means for restraining said front end support means at the lowermost position thereof;
- wherein when said front end support frame is located at the lowermost position, said uppermost bin tray is located below said rotating means, and said follower of uppermost bin tray is opposed to an engaging inlet portion of said rotating means.
