Abstract

PURPOSE:To eliminate the possibility of damaging the leading end of a sheet and lowering the transport speed by changing a paper path by means of course change rolls which are rotated in peripheral contact with each other. CONSTITUTION:While driving means 9 is not excited, course change rolls 2, 3 are located as shown in the drawings and rotated in direction of an arrow, so that a sheet 10 transported from the direction of an arrow (a) along a paper transport path 1 advances between the course change rolls 2, 3 and simultaneously the leading end thereof is deflected to a branch path 11. When the driving means 9 is operated to change the course of the sheet 10, an arm 5 is turned around a driving shaft 4 through a lever as shown in the drawing, the leading end of the sheet 10 transported from the arrow (a) along the paper transport path 1 is deflected to a branch path 12 by course change rolls 2, 3. In this system, the sheet is free from friction unlike the conventional systems, so that the sheet is prevented from damage, and the transport speed is not decreased.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a paper path switching device for a copying machine or the like in which a paper transport path is branched.

BACKGROUND ART Conventionally, as a paper conveyance path in a copying machine, etc., a path branched into two paths as shown in the first part is used. In the paper conveyance path as described above, a rotatable gate b is provided at the branch point α, and by switching the tip of this gate b to the loading position or storage position, the paper conveyed from the direction of arrow C is dt - The allocated amount is being conveyed in the direction of arrow C or the direction of arrow f. However, in the paper path switching device as described above, since the direction of the paper d is changed by the gate b, there is a problem in that the paper dK is burdened by frictional resistance with the gate b, and the conveyance speed of the paper d is reduced.

Purpose of the Invention The present invention has been made for the purpose of improving the above-mentioned problems, and provides a paper conveyance device for a copying machine or the like that allows the path to be changed without putting a burden on the paper, thereby preventing a decrease in the conveyance speed. This is what I am trying to do.

Structure of the Invention A pair of route changing rolls that rotate while circumferentially touching each other are provided at the entrance of the branching path of a paper conveyance path having a plurality of branching paths in the middle, and one of the path changing rolls is driven by a driving means as needed to move the other one of the path changing rolls. By moving in the tangential direction of the course change roll.

Leading edge of paper between each diverting roll? A paper path switching device for a copying machine, etc., which deflects paper in the direction of a branch path.

Embodiment An embodiment of the present invention will be described in detail with reference to the first page shown in the second page and below. Road 11*12
It is branched into.

Also, each branch road 11, I! A pair of course changing rolls 2 and 3 are provided at the entrance of the rotor, which circumferentially surround each other. One of the course changing rolls 2 is fixed to a drive shaft 4 and is rotated in the direction of the arrow by a drive source (not shown), and one end of an arm 5 is rotatably supported on the drive shaft. The other one of the course changing rolls 3 is rotatably attached to the middle of this arm 5.

On the other hand, the other end of the arm 5 projects outward from the paper transport wIl, and its tip is engaged with a long hole 7α provided at one end of the lever 7 via a pin 6. The lever 7 has an L-shape, for example, and has a bent portion rotatably supported on a support shaft 6, and a driving means 9 such as a solenoid is connected to the other end of the lever 7. Drive means 9
The arm 5 is rotated via the lever 7 as follows.

Next, to explain the operation, when the driving means 9 is not activated, each of the course changing rolls 2 and 3 is in the position shown in FIG. 2 and is rotating in the direction of the arrow. The paper 10 that has been transported from the direction of arrow A through the paper transport path 1 enters between the respective path changing rolls 2 and 3, and at the same time, its leading end is deflected toward the branch path 1. Furthermore, when the drive means 9 is operated to completely change the path of the paper 10, the arm 5 is rotated via the lever to the position shown in FIG. 3 about the drive shaft 4. The leading edge of the paper 10 that has been conveyed from the direction is diverted to the branch path 1. It can be deflected to the side.

Effects of the Invention As described in detail above, this invention allows the paper path to be simply changed using the course changing rolls that rotate while circumferentially contacting each other, and does not place a burden on the paper due to friction unlike conventional gates. Do not damage the leading edge of the paper.
There is no risk of reducing the conveyance speed. Further, since it can be easily constructed by a pair of course changing rolls and means for changing the position of these changing rolls by one unit, it can be provided at low cost.
