Abstract

PURPOSE:To make it possible to remove a jammed paper without breaking the latter, by providing such an arrangement that a paper feed system including a copying paper storing section, a paper feeding roller, paper conveying rolls and a guide plate may be pulled at one time. CONSTITUTION:Upon occurrence of trouble such as, for example, paper-jamming, a handle 3 on an elevator tray 1 is pulled backward to extract the elevator tray 1 in the direction orthogonal to the direction of paper-feeding. Thereby, a copying paper setting bed 12 together with a paper feeding roller 6, conveying rollers 8a, 8b, and a guide plate 10, which are all incorporated in the paper setting bed 12, are pulled out. Accordingly, the paper feed roll 6 and the conveying rollers 8a, 8b are visible so that a jammed paper may be taken out without being broken.

Description

Detailed Description of the Invention (Technical Field) The present invention enables the paper feed roller, conveyance roller, and guide plate to be pulled out together with the copy paper loading table at the same time, so that the copy paper will not be damaged even if a paper jam occurs. The present invention relates to a paper feeding device for a pine copying machine that can be removed by removing the paper.

(Prior art) As a conventional paper feed device for a copying machine, for example, a large amount of copy paper can be placed on a paper loading table, and the paper feeding level can be kept constant by raising the paper loading table as the copying paper is consumed. There are elevator trays that hold and allow continuous copying of large quantities. In the elevator tray, copy paper can be refilled on the paper tray by, for example, sliding the copy paper tray toward the front in a direction perpendicular to the paper feeding direction and pulling it out.

However, according to this copying machine paper feeding device, when a paper jam occurs due to diagonal feeding by the paper feeding roller, or when the copy paper stops with the leading edge caught in the conveying section,
In order to solve these problems, if you slide the paper tray out of the copier and pull it out toward you, the paper will be pulled and damaged by the pull-out operation, and the paper will remain inside the copier and cause other problems. There is a fear.

(Purpose and Structure of the Invention) The present invention has been made in view of the above, and in order to make it possible to remove copy paper without damaging it in the event of paper twisting, etc. To provide a paper feed device for a copying machine in which a paper roller, a conveyance roller, and a guide plate can be simultaneously slid and pulled out from the copying machine.

(Example) The paper feed device for a copying machine according to the present invention will be described in detail below.

FIGS. 1 and 2 show an embodiment of the present invention, in which guide rails 2 for sliding the elevator tray 1 are provided on both sides of the elevator tray 1, and a drawer handle 3 is provided on the front surface of the elevator tray 1. ing. A frame 4 is provided around the copy paper tray 12 on which the copy paper 7 is placed so as to surround the copy paper 7, and a paper feed roller drive shaft 5 is rotatably installed on the frame 4. A pair of paper feed rows 26 are provided which are driven by the paper feed roller drive shaft 5 (the paper feed rollers 6 are constantly in contact with the surface of the copy paper 7 due to the elevator mechanism of the elevator tray 1). Furthermore, conveyance roller drive shafts 8a and 8b are rotatably installed on the frame 4, and a pair of conveyance rollers 9a and 9b are respectively provided on the two conveyance roller drive shafts 8a+8b.
The conveyance roller 9a and the conveyance roller 9b are in contact at one point in order to convey the copy paper). Furthermore frame 4
A guide plate 10 is installed in which the copy paper 7 fed by the paper feed roller 6 is guided by transport rollers 9 a # 9 b K''!.

In the above configuration, if a problem such as a paper jam occurs, open the door of the copying machine 11, raise the handle 3 of the elevator tray 1, and pull the handle 3 toward you to move the elevator tray 1 in the paper feeding direction. Pull it out in the right angle direction. As a result, the paper feed roller 6, transport rollers 8a, 8b, and guide plate 10 can be pulled out at the same time as well as the copy paper loading table 12. If a problem occurs, the copy paper 7 can be easily removed without damaging the copy paper 7 causing the trouble.

(Effects of the Invention) According to the paper feeding device for a copying machine according to the present invention as described below, a paper feeding roller, a conveyance roller,
Since the guide plate and the guide plate can be simultaneously slid out of the copying machine and pulled out toward the front, when paper jam etc. occurs, it can be removed without damaging the copy paper.
