Abstract

PURPOSE:To simplify the construction of a course varying board while make it a low cost by forming a course varying board in such a way that guide pieces which guide sheets of papers in two directions is cut and raised from a sheet of metal plate. CONSTITUTION:A course varying board 2 is formed by a sheet of metal plate, from which guide pieces 2a, 2b that guide sheets of papers 10 to two directional courses A, B, are cut and raised. By making a cam 6, which is brought in contact with a pin 5 which is projected sideways from the end side of the thus formed course varying board 2, travel in the arrow directions by means of a solenoid 7, the end side of this course varying board 2 is rotated centering around the shaft 4a of one of transporting rolls 4. Following this rotation, the course of the sheets of papers 10 is varied from a course in the direction of A heading for the transporting rolls 4 to a course in the direction of B heading for other transporting rolls 8, being guided by the lower face of one of the guide pieces 2a.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a paper path changing device for a copying machine or the like that changes the path of a sheet on a paper conveyance path.

Prior Art In a conventional copying machine or the like, when changing the path of paper moving on a paper conveyance path, for example, a path change plate α as shown in FIG. 1 is provided on the conveyance path, and this path change plate α is rotated. By moving the sheet c, the course is changed in the t-d direction or the e direction.

However, this type of route changing device has a complicated structure, with the conveyor path being separated into four parts by the route changing plate α, so it requires a lot of installation space and requires a lot of effort to assemble. There was a problem.

OBJECT OF THE INVENTION The present invention has been made for the purpose of improving the above-mentioned problems, and provides a paper path changing device for a copying machine or the like in which the traveling direction of paper can be easily changed using a single plate.
The aim is to facilitate installation and reduce costs.

Structure of the Invention A path change plate is formed by cutting and raising guide pieces for guiding paper in two directions from a single metal plate, and this path change plate is installed in a paper conveyance path, and the path change plate is moved by an appropriate driving means. A paper path changing device for copying machines, etc. that allows the direction of paper travel to be changed by moving the leading edge up and down.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings shown in FIG. A step 1α is formed on the side, and the tip of the course changing plate 2 reaches this step 1α. The course change plate 2 is formed by bending a single metal plate, and a bracket 3 protruding from the bottom of the proximal end is attached to an axis 4α of a conveyance p-ru 4 provided in the direction of the course l. It is supported so that the distal end side can rotate around this shaft 4α to the position shown in FIG. This rotation is performed by moving a cam 6, which contacts a pin 5 projecting laterally from the tip side of the course guide plate 2, forward and backward in the direction of the arrow by means of a solenoid 7. Two pairs of tongue-like guide pieces 2α and 2b are cut and raised at the center of the plate. The guide piece 2α located on the distal end side of the course change plate 2 is longer than the guide piece 2b on the proximal end side, and is cut and raised diagonally downward toward the proximal end side, and the distal end portion is directed in the course B direction. The paper 10, which is guided by the lower surface of the guide piece 2α and advances, is supplied to the transport roll 8 on the path B.

On the other hand, a short guide piece 21I provided to face the guide piece 2α is also cut and raised diagonally downward, so that the leading edge of the paper 10 moving on the course changing plate 2 is directed to the guide piece 2α.
The part hanging down into the through hole 2c created by cutting and raising α, 2b is returned to the upper surface of the course changing plate 2.

Effects of the Invention As described in detail above, the present invention allows the course A to be set in two directions from the course changing board 2 made of a single piece of metal board.

Since the guide pieces 2α and 2b for guiding the paper IO to B are cut and raised, the structure is simple and can be provided at low cost.
The path of the paper 1o can be easily selected. Furthermore, since it can be made very thin using sheet metal, it can be easily installed in a small space, and since the guide portion is not divided into many pieces, it is easy to assemble.
