In the above configuration, set the copy reduction ratio for the original size using the reduction ratio setting button 121 (no operation is required if it is 100%), and select whether or not a paper cassette corresponding to this reduction ratio is installed. Confirm by indicator light 12g. If the appropriate cassette is not selected, select it using the tray selection button 12f, and if the applicable cassette is not found among the installed cassettes, install a separate paper feed cassette containing the appropriate paper. do. In this state, the document placement position is determined according to the reduction ratio, the register storage button 11 lights up, the position where the document should be placed (including horizontal and vertical directions) is displayed, and the document is placed according to the displayed contents. may be placed on the platen 10. Note that when the reduction ratio setting button 12N is not operated, the paper size of the paper feed cassette selected at that time is displayed by the register storage guide 11. When the start button 12dt- is pressed in this state, only one sheet of paper is sent from the selected paper feed cassette to the copying mechanism under the control of the control section, and thereafter, the sheets are sequentially fed until the set number of sheets is reached.

However, with conventional electronic copying devices, the tray selection and registration guide are treated as separate items, even though they are closely related, so the registration guide only displays the document placement direction. , the paper size of the cassette was displayed by the selection indicator light 12g. This makes operation difficult, and there are many operation buttons on the console, which may lead to operational errors.

[Object and structure of the invention]

The present invention has been made in view of the above, and provides a paper selection switch that selects a paper size determined based on the original size and the reduction ratio, in order to improve the usability of the original size switch and simplify the console section. The present invention provides an electronic copying machine device in which the display lamp is integrated with the indicator light of the register storage and guide.
