Abstract
A paper tray arrangement is disclosed for receiving a stack of paper and which is insertable into a receiving device of a copying machine or the like and which includes a supporting plate for the stack of paper and springs applied to the supporting plate to lift the supporting plate off the bottom of the tray. Tensioning apparatus is provided for the springs and a stop of the receiving device is assigned to the tensioning device in such a manner that the spring is tensioned when the paper tray is inserted into the receiving device and is relaxed when the paper tray is taken out of the receiving device.
Claims19
A paper tray arrangement for receiving a stack of paper and which is insertable into a receiving device of a copying machine, comprising:
- a supporting plate for the stack of paper,
- at least one spring applied directly to the supporting plate to lift the supporting plate off the bottom of the tray,
- tensioning apparatus for the at least one spring,
- and a stop on the receiving device engageable with the tensioning apparatus in such a manner that the spring is progressively tensioned only when the paper tray is inserted into the receiving device and is progressively relaxed only when the paper tray is taken out of the receiving device.
A paper tray arrangement for receiving a stack of paper and which is insertable into a receiving device of a copying machine comprising:
- a supporting plate for the stack of paper,
- at least one spring applied to the supporting plate to lift the supporting plate off the bottom of the tray,
- tensioning apparatus for the at least one spring,
- and a stop of the receiving device assigned to the tensioning apparatus in such a manner that the spring is tensioned when the paper tray is inserted into the receiving device and is relaxed when the paper tray is taken out of the receiving device,
- wherein said at least one spring includes one tension spring respectively pivotally connected on both sides to the supporting plate laterally next to the paper stack, and wherein said tensioning apparatus includes a respectively assigned tensioning apparatus for each tension spring.
A paper tray arrangement for receiving a stack of paper and which is insertable into a receiving device of a copying machine, comprising:
- a supporting plate for the stack of paper,
- at least one spring applied to the supporting plate to lift the supporting plate off the bottom of the tray,
- tensioning apparatus for the at least one spring,
- and a stop of the receiving device assigned to the tensioning apparatus in such a manner that the spring is tensioned when the paper tray is inserted into the receiving device and is relaxed when the paper tray is taken out of the receiving device,
- wherein the tensioning apparatus includes a disk which is pivotally disposed in a pertaining lateral wall of the paper tray and to the circumference of which one end of the tension spring respectively is fastened.
A paper tray arrangement for receiving a stack of paper and which is insertable into a receiving device of a copying machine, comprising:
- a supporting plate for the stack of paper,
- at least one spring applied directly to the supporting plate to lift the supporting plate off the bottom of the tray,
- tensioning apparatus for the at least one spring,
- and a stop on the receiving device engageable with the tensioning apparatus so that the spring is automatically tensioned only when the paper tray is inserted into the receiving device and is automatically relaxed only when the paper tray is removed from the receiving device, with said automatic relaxation of the spring being effected without any steps other than removal of the paper tray from the receiving device and consequent disengagement of the stop and the tensioning apparatus.
