Abstract

PURPOSE:To offer always the copy which the user desires, by providing a paper quality setting means in the paper feeding part of a copying machine and comparing not only the paper size but also paper quality information and generating a selecting signal only for coincidence. CONSTITUTION:Papers are supplied to the copying machine from an upper-stage paper feeding part 1 and a lower-stage paper feeding part 2 by a paper feeding rolls 3 and 4. Information from not only no-paper detecting means 8 and 9 in parts 1 and 2, paper size detecting means 10 and 11 in parts 1 and 2, and upper stage and lower stage setters 12 and 13 which select either of the upper-stage paper feeding part 1 and the lower-stage paper feeding part 2 but also a paper quality setter 14 are inputted to a controlling circuit 15. The controlling circuit 15 performs processings for these information to output a cut signal 16, an upper stage paper feed signal 17, a lower stage paper feed signal 18, or the like as a control output signal. The paper quality setter 14 consists of a paper thickness setting part, a paper type setting part where different paper types are set by the transmittance of the paper, and a paper color setting part.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic switching and selection mechanism for paper feed sections in a copying machine having multiple stages of paper feed sections.

Conventionally, in order to improve copying efficiency, it has been common to provide multiple stages of paper feeding sections, both in the case of roll feeding and in the case of cassette feeding. In this case, in addition to switching and selecting paper of different sizes, if you set paper of the same size in multiple paper sources, and the selected paper source runs out of paper, the same size paper will be automatically matched. Various configurations have also been proposed in which paper of different sizes can be switched and selected from paper feed units.

However, now the paper used as transfer paper not only has different signatures, but also has different paper quality. In other words, the thickness of the paper, the transparency of the paper, the color of the paper, etc. have come to be selected in succession depending on the purpose.The thickness of the paper is 55Kf paper, 60Kf paper, etc.・・・

Therefore, when automatically switching the paper feed section, if the switching is performed simply based on the information that the paper is of the same size, there is a risk that a copy may be made with a paper quality that is not requested by the user.

The present invention has been made in view of the above circumstances,
When paper fish detection is performed on the selected paper source, when automatically switching to another paper source, not only the paper size but also the six paper quality information are compared, and a selection signal is generated only when they match. By doing so, the aim is to always provide the user with the desired copy.

That is, in FIG. 2, the paper size detection means 8, 9 and the paper size detection means 10 and 11 of the upper paper feed section, the lower paper feed section, and either the upper paper feed section 1 or the lower paper feed section 2 are detected. There is a paper quality setting device 1 in addition to the upper setting device 12 and the lower setting device 18 to be selected.
The information from 4 is manually input to the control circuit 15. After processing this information in this control (b) path 15, the cut No. 1 16 is output as a control output signal.
, an upper paper feed signal 17, a lower paper feed signal 18, etc. are output. The cut signal 16 activates the cutter unit 6, and the upper paper feed signal 17 indicates that the lower paper feed section 2 is selected. This is the signal that is issued when paper of the same size and quality is loaded. The lower paper feed signal 18 is a signal in the completely opposite case.

FIG. 4 shows the layout of the switch groups 19, 20, and 21 of the paper quality setting device 14 on the panel display section 25 provided on the surface of the copying machine. The switch column 19 of the paper thickness setting section 14a includes switches for standard paper of 55Kf, 84.5Kg, thin paper of 40Kf, 70 o'clock, 90 o'clock, 11 OKf, thick paper of 185 edge, and others. Further, the paper type setting section 14b (1) The switch group 20 includes switches for plain paper, tracing paper TA8Q, TA70, -q illustrator-g, OHP paper, and SO17)&. Furthermore, the switch group 21 of the paper color setting section 14c is set to white, "#, pink, yellow, others, etc.
It consists of each switch. Each of these switches is configured such that only one switch can be selected from each switch group. When selecting standard paper, select the leftmost vertical column (5). In addition, if you select the "Others" switch, the automatic switching of the paper feed section may be determined in the machine control circuit.Also, these switch groups are the upper paper feed section L, the lower paper feed section L, and the lower paper feed section. When paper is set in each paper feed section 1, 2, the correct answer for this paper is selected from the switch group and this switch is pressed.This causes each decoder 22, 28, . Information is input to the control circuit 15 via 24.

For example, assume that the same size and quality of paper is set in both the upper and lower shelves, and that the upper paper feed section l is selected first. Then, when the paper runs out in the middle of copying a large number of sheets and a paper signal is input from the upper paper feed section 8 to the control circuit 15, the control circuit 15 determines the paper size of the lower paper feed section, the paper size and the L. Since they are the same, an output is sent to the lower paper feed signal 18, and the lower paper feed section 2 is automatically switched.
