JPS58112773A - Feeder for continuous paper - Google Patents

Abstract

PURPOSE:To provide the titled feeder which eliminates the need to stop the feed to a continuous paper and enables to contrive an increase of speed of a recording operation, by a method wherein one page on each side of a spliced part of a continuous paper is fed without any recording thereon. CONSTITUTION:The paper 71 contained in a hopper and the paper 72 to be used next are spliced to each other by a splicing tape 8 having a reflectivity different from that of the paper 7. When the tape 8 comes to a detecting position 13, it is detected by a detector 14, which feeds a detection signal to a controlling mechanism 1. The mechanism 1 so controls that electrostatic latent images by a laser beam 2 are formed on the page parts on the forward side of the spliced part except the page part having the spliced part, and then the production of the latent image for the next data on the paper 7 is started after feeding the paper 7 by an amount of two pages.

Description

[Detailed description of the invention] Book! 1 is related to a continuous paper conveying device κ in a device κ equipped with a mechanism for conveying continuous paper such as a laser beam printer. A renkei transporter that can be transported! There are 6 things related to relocation.

Conventionally, tin slices of continuous paper were used for 20 so * tc *, and the printing operation was stopped, the end of the continuous paper and the beginning of the next continuous paper were pasted together with a splicing chive, and the splice part was used as the stack of continuous paper. This method involves feeding the continuous paper until it enters the printer, and then restarting the κ printing operation.0 However, with this method, the conveyance of the continuous paper must be temporarily stopped, which reduces the high-speed printing speed. There are problems in that continuous conveyance cannot be easily carried out because the unevenness at the front and back of the tin slice section of the continuous paper, which has disadvantages, causes transfer defects and the like.

Therefore, an object of the present invention is to provide a new continuous paper conveying device that is improved in view of the above-mentioned drawbacks. Another object of the present invention is to stop the progress of continuous paper being conveyed. The present invention relates to a continuous paper conveying device that can convey a continuous sheet of paper while controlling recording operations without any problem.

That is, the main structure of the present invention capable of achieving the above object is a continuous paper conveying device in which a plurality of 11 papers are connected, splicing continuous paper, and continuously conveying the continuous paper to the recording section. A detection means for detecting the splice part is installed in the upstream direction, and the signals from the detection means are used to record the sheets before and after the tin slice part. The recording process is controlled so as to carry out the mold cultivation, and the nine continuous paper conveying devices are used to feed mold.
151. The figure is a sectional view showing an embodiment of the present invention. In the figure, a data #i allocation mechanism 1 modulates a laser f-beam 2 and forms an image on a photosensitive drum 3 to form an electrostatic latent image. The above electrostatic latent image is developed in the developing device 4.
Then, the image is transferred onto the paper 7 by the transfer charger 10. By the way, the paper 71 in the hopper is transported by the tractor 9. Transfer charger 1
0. It passes through the tractor 11 and the fixing device 12, and is folded into the stacker and enters the friend paper 7sK. The image transferred onto the paper 7 by the transfer charger 10 is fixed onto the paper 7 by heating or pressure by a pair of fixing rollers 12 . 8
is a splicing tape with a different reflectance from 117, for example, it is coated with aluminum! Iller's tape. The tin rising tape 8 is the paper 71 in the hopper.
The paper 72 to be used next is pasted together.

14 is an a5 detector and a light emitter 5. It includes a light receiver 6 and detects the reflectance on the paper 7. The presence of the tin rising tape 8 on the paper 7 is detected and connected to the detected output expansion control mechanism 1.

In the above configuration, the printing operation for the paper 71 is performed, and during the printing operation for the paper 71, the next paper 7 is connected with the tin rising tape 8. When the splicing tape 8 eventually reaches the detection position 13, the detector 14 detects the splicing tape 8, and the detection signal is sent to the control mechanism 1. The control mechanism 1 controls the laser source 2 to form an electrostatic latent image up to each sheet one page before the splice portion, and then delays the formation of the electrostatic latent image of the next data by two pages. . In other words, the paper is simply fed without performing the printing operation for each sheet page before and after the spliced part, and the printing operation is resumed from the next page υ). In the above embodiment, the detector 14 is a reflective Although the original charge detector is used, it is also possible to detect with a transparent charge detector. Using tin rising tape 8 as a magnetic tape,
It is also possible to detect with a magnetic head, and various detection methods can be considered. It can be performed continuously without stopping, and the speed of recording processing can be increased.
