Abstract

PURPOSE:To eliminate such irrationality that a copy is taken without increasing the counted value of a key counter by stopping a copy cycle and handling a jam when the key counter is pulled out before the key counter counts up. CONSTITUTION:The key counter 5 is inserted and an operation part 6 is put in operation to start a copying process. It is discriminated in the middle whether the key counter is still inserted or not, and when the key counter is inserted, the copying processing is advanced in prescribed order and the key counter 5 counts up. A count-up signal is outputted to the key counter 5 from an arithmetic processing part 4 on the basis of the output of a paper discharge sensor. If the key counter is pulled out in the middle of the copying process, that is detected and jam processing is carried out; and the copy cycle is stopped and a jam warning display is made. Copy paper is not detected by the paper ejecting sensor, so the key counter does not count up.

Description

[Detailed description of the invention] (B9 Industrial application fields The present invention relates to a copying machine having a key counter.

(Rough Prior ArtCurrently, copying machines such as electrophotographic copying machines are widely used, and each copying machine is equipped with a counter that counts the number of copies made due to the needs of the user or the need for maintenance management.) .

On the other hand, in order to keep track of the number of copies of the department's good fortune for management purposes, companies and other organizations have key counters installed in each department, and copies are made only when this key counter is inserted into the designated position of the copying machine. Nowadays, key counter type copying machines are being used in which the number of copies is cumulatively counted each time one copy is made.

In this type of key counter copying machine, the timing at which the key counter counts the number of copies varies depending on the model. In a copying machine that counts up when a paper is detected by the paper discharge sensor, if the key counter is removed before the paper discharge is detected by the paper discharge sensor, it is unreasonable that copying can be performed without being counted by the key counter.

In order to prevent such unreasonableness from occurring, it is possible to extract the count-up signal of the key counter at the early stage of the copying cycle, but if a paper jam (so-called jam) occurs afterwards, I also counted it and this is also inappropriate J! It is 1j.

←Object and structure of the invention The present invention has been made in view of the points mentioned in ``-4.
In a'JJ'4m with key counter.

The purpose is to prevent the key from being removed and copied before the key counter counts up, and for that purpose, the key counter will count up.If the key counter is removed, the copy cycle will be stopped and a jam will be displayed. It is composed of

FIG. 1 shows an overall configuration diagram of the present invention.

The presence or absence of a key counter before the key counter counts up is detected by the key counter detection means, and when a failure without a key counter is detected, the copying cycle is stopped by the control means, and a jam is displayed by the display means. It was designed to do this.

) Example The present invention will be explained below based on the drawings.

FIG. 2 shows a control circuit of a copying machine having a key counter according to the present invention. Reference numeral 1 denotes electrical and mechanical loads for carrying out the copying process, such as a motor for driving the document table or photosensitive drum j, or a charging electrode, For example, one transfer pole and one separation pole. 2
is a moving circuit in which these f′l loads are 1< moving 1, 3
is the sensor input circuit such as the paper feed sensor and paper ejection sensor,
4 is a Jf processor such as a microcomputer that controls the copying process. In part 11, 5 is a key counter, and 6 is an operation unit for setting copying conditions and the like.

Next, the copying operation of the copying machine having the above structure when the key counter according to the present invention is removed will be described with reference to FIG.

A series of copying processes is started by inserting the key counter and operating the operating section 6 (F-1). While the copying process is being performed sequentially, it is determined whether or not the key counter is inserted (F-2). If it is inserted, the copying process proceeds in a predetermined order and the key counter counts up. . This count-up signal is output from the arithmetic processing section 4 to the key counter 5 based on the output of the paper discharge sensor. The presence or absence of the key counter is checked repeatedly until the iM copying cycle is completed (F-4), and when the copying cycle is completed, the standby mode advances (F-5).

On the other hand, if the key counter is removed during the copying process, this is detected in step (F-2) and jam processing (F-6) is performed. In this process, the copying cycle is stopped and a jam warning is displayed.In this case, the paper ejection sensor does not detect the copy paper, so as a natural result, the key counter counts up. If the key is removed in the middle of the copying process, the copying cycle is stopped and the jam is cleared, so there is no unreasonable situation where only copying is performed without increasing the count of the key counter.

Effects of the Invention - 1 - As explained above, in the present invention, when the key counter is removed before the key counter counts up, the copying cycle is stopped and the jam is cleared.
It is possible to prevent the unreasonable situation in which copying is possible without increasing the count of the key counter.
