JPS58114981A - Identification system for withdrawal of inserter medium - Google Patents

Abstract

PURPOSE:To prevent printing without paper in a printer with an inserter by inspecting a paper immediately before the printing following the instruction of the printing in addition to inspection of the state thereof after the shifting of the line to allow identification of an operator's withdrawal of the paper. CONSTITUTION:When a paper 1 is inserted into an inserter 10, it is automatically sucked and the initial position thereof is set as indicated by the arrow 5 on a platen 2 with a paper end detection sensor 3 and a line shift position sensor 4 provided on a passage. Then, one line is printed according to input information and shifted. After the line shifting, the presence of the paper 1 is checked for with the paper end detection sensor 3. The sensor checks to see if paper presents thereon 3 immediately before the start of printing after the instruction of printing. When the inspection after the line shifting indicates the presence of paper and that immediately before the printing the presence of no paper 1, with a judgement that an operator withdraws the paper 1, an alarm sounds.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention This invention relates to a separate method for pulling out the inserter rope body in which the operator pulls out the printing medium in a printing device with an inserter.

(2) Prior art and checking point Conventionally, in a printing device such as a kanji printer equipped with an inserter, as shown in FIG. When inserted, the initial position of the medium end detection sensor 3 and line feed position detection sensor 4 provided in the passage is set to the position indicated by the arrow 5 on the platen 2.Next, the input information is When one line is printed, a line feed is started.At the end of this line feed, the medium end detection layer/?5 inspects the presence or absence of the medium, and if it is ``present'', the process proceeds to the next step, and if it is ``absent'', printing is performed. This is sufficient under normal conditions, but often the operator makes a mistake in the type of paper, etc., and then pulls out paper 1 outside at the 9 o'clock line feed position.

Current equipment does not have a means to identify such operations, so there is a risk that curling and subsequent overprinting of hot paper will occur.

An object of the present invention is to provide an inserter fabric drawing and fiber separation method that allows an operator to pull out print media in different ways in a printing device with an inserter.

(4) Structure of the Invention In order to achieve the purpose of cocooning, the inserter medium withdrawal identification system of the present invention inhales the print medium every evening, feeds the print medium to the line to be printed, and returns the line to the line to be printed at the end of 70 days. Printing that checks the medium's I#@ using the medium detection center and prints with the print command! 1!
At the position i, mark '# command wave Just to the right to start printing, there is a medium next time (Mlitft), there is a medium at horizontal 1 after the line break), and there is no medium before printing m. Extraction of the p1 gland body by 1 krJ is considered to be a threat to the body.

(5) Examples of the invention FIG. 2 is a flowchart showing the procedure for producing the mounting part of the present invention.

Conventionally, the detection of the presence of a swallow in the edge body was performed after the line break was set, so the operation was immediately started with the ton or - character command. In contrast, in the present invention, as shown in the figure, when there is a print command, it is checked whether or not the medium suction position is reached, and if it is OK, it is checked whether or not there is a medium at the medium suction position. If this is found, another check is performed just before printing so that the printing operation can proceed. This means that the operator can
This is because it is counted at ρ time.

This makes it possible to generate an alarm even when the paper is being pulled out or even after it has been pulled out.

No. 5Iiii1 is the structure of the superimposed embodiment.

In the same figure, the medium detection sensors 11 are numbered 10 including, for example, J11, figure 01s, body work/de detection center tS.

This Sen? 11C) The detection signal is branched and a positive signal and an inverted signal are set to 0 on each side, and a line feed end timing signal from a processor (not shown) is input as another input. AND 1m path 12 circuits 50 outputs 7 rip 70 ts (Fj') 140&.

R terminal, and the IIDQ output is connected to the medium detection sensor 110.
Insert it into AND circuit 15 along with the output, and output FF1.
Jujii with 4's Q output and 0 print command from Pupuryu Tuna! When the circuit 14 is input and each signal is in the 0 state, it is determined whether there is a pullout or not.

In this configuration, mND gate 12.15 and j'j"1
The 40 circuit indicates that the medium is in bad condition at the end of the line feed, and if the Q output is at a high level, a print command is executed,
Furthermore, the next line feed is performed. When the Q output is inverted to level 4, it indicates the paper end, so the section is stopped and #- is performed.

Book 9! After detecting the state at the end of the line feed, in other words, as shown in FIG. It is detected by In other words, even if the Q output of FF 14 is at a high level as a foreshadowing at the end of the line feed, if the output of FF 11 changes to a low level, the output of ANDIgl path 15 will be Become world level. Therefore, if the change of this output to a low level is determined in relation to the time of the print command, it is possible to distinguish the baldness tJl of the extraction.

It is clear that if the fJ is completely removed, the Q and Q outputs of Fji"14 will be reversed.

(6) As described in detail, according to the present invention, in addition to inspecting the state of the medium after a line break, the operator can remove the medium by placing it horizontally immediately before printing after a printing command. It is possible to distinguish the pulling out of the machine and generate an alarm, so if there is no paper 0II
This makes it easier to prevent the risk of printing on k-shoes.

Claims (1)

[Claims] The inserter sucks in the print medium, and when the line feed is completed, the medium detection sensor detects the presence of the print medium M1i.
In a printing device that prints with a tdi printing command,
After printing/confirmation, just before starting printing, remove the 4fs of the tanzo green body, place the medium horizontally after the line break, and check that there is no medium, and check that there is no medium.恢I! This is a separate method for inserter media removal and removal.
