Abstract

PURPOSE:To prevent such trouble that a user forgets setting a reserved document and is left unset not by insuring the completion of reservation setting the reserved document is not set at the time of reservation setting. CONSTITUTION:A comparator 39 compares detected outputs from document detecting sensors 11 and 12 with a reference value, and if the outputs detected by the sensors are less than the reference value, the comparator 39 outputs a document unsetting signal to a microprocessor 30. According to the result compared by the comparator 39, the microprocessor 39 decides whether the reserved document is set or not. If there is no reserved document in an automatic document feeder ADF at the time of reservation setting, reservation setting is retained. Consequently, such trouble that the document is left unset and reserved copying is not executed when setting is completed if a user forgets setting the reserved document is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a copying machine equipped with a reservation function for automatically copying a reserved original set in an automatic document feeder (ADF).

<Prior Art> A conventional copying machine with a reservation function is configured to cancel a reservation or erase reservation contents using a reservation cancellation switch provided on an ADF operating section. However, conventional methods do not detect the center status of reserved originals, so once a reserved original is set and then removed from the ADF's document tray, reserved copying starts as a blank original unless the reservation cancel switch is pressed. Furthermore, if the settings are completed without setting the reserved original, the original is left unset and the reserved copying is not executed. Furthermore, if a reservation cancellation switch is provided, an inexperienced operator may easily cancel a reservation after making a reservation, or an operator who is not familiar with the reservation settings may mistakenly operate the reservation cancellation switch and change the reservation settings. This also has disadvantages, such as erasing reservation cancellation switches, increasing costs, and complicating the operation section.

<Purpose of the Invention> In view of the above-mentioned conventional problems, the present invention provides a method for suspending the completion of the reservation setting if there is no reserved manuscript in A. The purpose is to provide a copying machine with a reservation function.

<Structure and Effects of the Invention> The present invention provides a copying machine equipped with a reservation function for automatically copying a reserved original set in an automatic document feeder, which is configured to accept reservation settings for copy processing conditions for the reserved original. means for instructing the setting means to complete the reservation setting; and storage means for storing the copy processing conditions set by the setting means when the instruction means instructs the completion of the reservation setting. , a detection means for detecting the presence or absence of a reserved document in the automatic document feeder; and a holding means for suspending completion of the reservation setting by the instruction means when the detection means detects that there is no reserved document during reservation setting by the setting means. and, after the reservation setting by the instruction means is completed, the copying process is performed based on the copying processing conditions stored in the storage means.

With the above configuration, according to the present invention, the reservation setting cannot be completed unless the reserved original is set at the time of setting the reservation, so it is possible to prevent troubles such as forgetting to set the reserved original and leaving the original in an unset state. In addition, you can reserve the copy processing conditions for a reserved original before setting it, and this reservation setting can be done while the copying process for other originals is in progress, reducing work time. can be realized.

<Embodiment> FIG. 2 is an overall structural diagram of a copying machine with a reservation function which is an embodiment of the present invention.

Reference numeral 7 denotes an ADF mounted on the upper part of the copying machine main body 1, and has a two-stage reserved document table 9 and 10. 8 is reserved manuscript table 9.1
This is a document conveying belt that conveys reserved documents set at 0 one by one to the exposure position of the copying machine main body 1, and discharges the copied documents to the document discharge tray 13 side above the ADF 7 after the copying process is completed.

1). A document detection sensor 12 detects the presence or absence of a reserved document on the reserved document tables 9 and 10, and corresponds to the detection means of the present invention.

Figure 3 shows the document detection sensor 1) placed on the reserved document table. 1
FIG. 2 is a layout diagram of No. 2. The document detection sensor l1)2 is composed of a light emitter/receiver, and emits light onto a reflective sheet 20 provided on a reserved document table 9, 10, and receives the reflected light to detect whether a reserved document is set on the document table. Detect. When a reserved original is set, the amount of light received by the sensor decreases, and the set of the original is detected. Reference numeral 8 is a paper feed roller that is lowered by a moving mechanism such as a solenoid (not shown) and feeds the reserved original on the document table, as shown by the two-dot chain line. This is a pair of separation rollers for separating the sheets one by one.

14 is a sorter for sorting and storing copy sheets, and has a plurality of bins 15. A bin 16 exclusively for reservations is provided at the bottom. Copy paper for reserved copying is in Bin 1
It is discharged at 6. Reference numeral 17 denotes a bin empty sensor for detecting whether or not copy paper is discharged into the bin 16.

FIG. 4 is a schematic block diagram of the ADF control section. The detection outputs of the document detection sensors 1) and 12 are compared with a reference value by a comparator 39. When the sensor detection output is less than the reference value, the comparator 39 outputs a document not set signal to the microphone 1 coprocessor 30. The microprocessor 30 is a comparator 39
Based on the comparison result, it is determined whether the reserved original is set or not.

The ADF operation section 31 has an E stage reservation key 32. A lower reservation key 33 and a reservation memory key 34 are provided. The reservation memory key 34 is an instruction means of the present invention for instructing completion of reservation setting. Upper reservation key 32. Lower reservation key 33
A reservation display 2335.36 is provided for each. Reference numerals 37 and 38 are a display for prompting the cents of a reserved manuscript and a display for indicating that a manuscript has been left behind. In the figure, the shaded display indicates a blinking or lighting state.

To make a reservation, first press the reservation key on an empty document table. Then, the document set display 37 blinks to prompt the user to set the document, and the reservation display 35 or 36 corresponding to the reservation key pressed at this time also blinks. Next, when the reserved original is set on the original table, the original set display on the display 37 disappears.Next, copy conditions such as the number of original copies, copy paper size, density, etc. are input, and the reservation memory key 34 is pressed. By operating this key, the reservation details are stored in memory, the reservation setting is completed, and the reservation display of the selected reservation manuscript table changes from blinking to lit.

At this time, if the pin empty sensor 17 detects that the reservation exclusive bin 16 is not empty, the reservation memory key 3
Even if 4 is pressed, the reservation contents are not memorized and the completion of the reservation setting is put on hold. Incidentally, if there is a document remaining on the reserved document table after ADF copying is completed, the display 38 blinks to indicate that the document has been left behind.

Next, the reservation setting process will be explained with reference to FIGS. 1(8) and (B).

First, it is assumed that a document is set on a reserved document table in one stage. In step nl (hereinafter, 1 step ni will be simply referred to as ni), the number i of reserved document table sets is set to 1.

Reservation settings in the standby state until the start of normal ADF copying are performed in steps 02 to n4. The reservation setting when the print start switch PSW (not shown) is pressed and normal ADF copying is started is performed by interrupt processing of n7 to n9. n20 to n25 correspond to the reservation setting processing routine JOBI of n2 and n7.

To set a reservation when in standby mode, first set the number of sets i with n20.
It is determined whether or not the number of originals is less than or equal to the number of originals M (=2).

In this case, since i=1 (<2), the reservation is accepted. When reservation key 32 or 33 is pressed (n21)
, accepts input of copy processing conditions (n22). This n
22 corresponds to the setting means of this invention. After setting the copy processing conditions, determine whether a reserved original is set on the reserved original platen 9 or IO (n23), and when the original detection sensor 1) or 12 detects the original cent, use the reservation memory key 34. Completion of the reservation setting is accepted, and on the other hand, when it is detected that the original is not set, the completion of the reservation setting by the reservation memory key 34 is not accepted until the original is sent (n23, n24). Step n23 corresponds to the holding means of the present invention, and the completion of the reservation setting is put on hold by the process from n23 to n22. This makes it possible to prevent reserved copying from being performed with a blank original if the user forgets the reserved original. When a document is set and the reservation memory key 34 is pressed, the reservation contents are stored and the set number i is incremented by 1 (n25). This n25 corresponds to the storage means of the present invention.

When the reservation setting is completed using the above JOBI, the cent status of the reserved document is determined again in n3.

When the original detection sensor 1) or 12 detects that the original has not been removed and it is determined that the original has been removed after setting the reservation, the reservation is canceled and the reservation contents are cleared (n4), and the original is not removed and is normal. If set to , complete reservation settings. After setting the reservation, when the print start switch PSW is pressed, ADF copying starts for the document placed before the reserved document (n5).

When making a reservation while ADF copying is being executed, the reservation is set using the JOBI during the copying process (n6.nlo, n1l) (n'7 to n9). If the reservation settings are not completed and the reservation document is detected to have been removed after the settings are completed, the reservation is canceled and the reservation contents are cleared (n 23.
n24. n8n9).
