Abstract

PURPOSE:To facilitate paper jam clearing operation by providing a plurality of transports with sensors for checking a paper jam, and driving the transports for transporting a sheet independently to stop the transport where a jam is caused. CONSTITUTION:A paper transport system of a copying machine is constructed by sequentially disposing a vertical transport 2 arranged along a plurality of paper trays 1, a registration transport 3, a transfer portion 4 for transferring a developer on a photosensitive material 8 to a copy sheet, a pre-fuser transport 5, a fuser (heat fixing roll) 6 and an output transport 7. In this case, driving systems for the respective transports are provided with sensors A-G for checking a paper jam. When one of sensors A-G detects a paper jam, the transports for transporting a sheet are driven independently, whereby the transport where a paper jam is caused is controlled to stop individually.

BACKGROUND OF THE INVENTION Although various improvements have been attempted to improve the performance of current copying machines, paper jams still frequently occur in paper conveyance systems. When this paper jam occurs, removing one jammed sheet becomes a troublesome operation for the operator. Especially in high-speed copying machines, when one sheet is loaded,
A large number of sheets of copy paper remain in the machine, and it is necessary to remove all of the copy paper, which reduces work efficiency and leads to operator distrust of the copy machine.

Structure of the Invention The paper conveyance system of a copying machine according to the present invention is configured such that each transporter of the V paper conveyance system is driven independently, and a sensor for detecting paper jam is installed at a predetermined position of each transport. This system is characterized in that it is connected to the drive system of each transport to individually stop the transport at the location where a single paper jam occurs, making it easier to remove a single paper jam and improving work efficiency. Note that the term "transport" herein refers to all conveyance means, regardless of their type.

■ When sensor C detects a paper jam, the registration transport 3 stops and the supply of copy paper is stopped. The copy paper after the registration transport 3 is ejected to a desired tray or the like. Since the conveyance of the copy paper before the registration transport 3 is stopped, after this is detected by the sensor B, the particle transport 2 is stopped, and thereafter it is used as it is in the next cycle.

In this case, there are still some copies of paper left in the copying machine, but a purge cycle is performed (when you press Start Print, the copies in registration transport 3 and beyond are ejected to unused trays. After the leading edge of the copy paper before the registration transport 3 is detected by the sensor B, the particle transport 2 is stopped, and the copy paper is then used in the next cycle.

In order to protect the photosensitive material 8, a brake is applied to the photosensitive material 8 and the photosensitive material 8 is stopped instantly. Copy sheets from the print user transport 5 onward are discharged to a desired tray or the like. For copy paper before registration transport 3, after the leading edge is detected by sensor B, particle transport is stopped, and the paper is then used in the next cycle. The copy paper in the registration transport 3 is purged and discharged to an unused tray.

Effects of the Invention As described above, the paper transport system of the copying machine according to the present invention independently drives each transport for transporting one sheet, and
Since the transport is stopped individually at the location where paper jam occurs, the copy paper in other transports is ejected to the desired tray, and all that is required is to remove the copy paper from only one paper jam location. The operator's annoyance is greatly reduced.Furthermore, since some of the copy paper is used as is in the next cycle, there is an advantage that waste that would previously have been discarded can be eliminated.
