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 reservation document set in advance on a document table.

<Summary of the Invention> The copying machine with a reservation function according to the present invention interrupts the copying process of the reserved copy when another user approaches the copying machine to make a normal copy, for example, in the middle of a reserved copy. The copying is restarted after the copying is completed, and the reserved copying is executed only during a preset reserved copying execution time period.

<Prior Art> A conventional copying machine with a reservation function is configured such that once reserved copying starts, it does not allow interruptions for copies other than reservations during reserved copying unless the reserved copying is ended. For this reason, once the reserved copy has started, even if the user comes to the copying machine to make a copy other than the reserved one, he or she has to wait until the reserved copy is finished. However, if the amount of reserved copying is large, it will take a long time to complete, resulting in a large waiting time loss, and the scheduled copying that is in progress may be finished at a certain time, such as in the morning of the same day. Even in non-urgent cases where it is only necessary to turn on the copier, there is a problem in that it is not possible to give priority to copying that needs to be done urgently, reducing the efficiency of use of the copying machine.

<Object of the Invention> In view of the above-mentioned problems, the present invention provides a copying machine with a reservation function that executes reservation copying when normal copying is not being performed and allows urgent copying etc. to be interrupted in the middle of execution of reserved copying. The purpose is to provide a machine.

<Configuration and Effects of the Invention> FIG. 1 is a diagram for explaining the configuration of the present invention. A human body detection sensor is provided on the front of the copying machine. The output effect of the human body detection sensor and the copy mode (whether the normal copy mode is the reserved copy mode) are input to the reserved copy interrupting means. The reserved copy interrupting means does not interrupt the copy process even when a human body is detected by the human body detection sensor in the normal copy mode, but in the reserved copy mode, the copy process (reserved copy) is performed in response to the detection of a human body by the human body detection sensor. Interrupt.

According to the present invention with the above configuration, when a user approaches the copying machine to make a normal copy while a reserved copy is in progress, for example, the execution of the reserved copy is interrupted and interruption of the copy is permitted. Therefore,
To give priority to urgent copies over reserved copies, to eliminate waiting time loss due to waiting for a large amount of reserved copies to be completed, and to improve the utilization efficiency of a copying machine. In addition, if you avoid times when the copier is used frequently and set a scheduled copy execution time during a free time such as lunch break when normal copying is not done, scheduled copying will only be performed during that set time. Therefore, non-urgent or large-volume reserved copying can be performed without interfering with normal copying, and the copying machine with the reservation function can be used efficiently.

<Embodiment> FIG. 3 is an overall structural diagram of a copying machine with a reservation function, which is an embodiment of the present invention.

Reference numeral 1 denotes a main body of a copying machine in which a copying process mechanism including a photosensitive drum 2 is built. Paper feed cassettes 3 and 4 are loaded into the main body 1 of the copying machine. Reference numerals 5 and 6 indicate cassette empty detection sensors for detecting loading of the paper feed cassette.

Reference numeral 7 denotes an ADF mounted on the upper part of the copying machine main body 1, and has two reserved document tables 9 and 10. Reference numeral 8 conveys reserved originals set on reserved original tables 9 and 10 to the exposure position of the copying machine main body 1, and after the exposure process is completed, the copied originals are transferred to the original output tray 1 on the upper part of the ADF 7.
This is the document conveyance belt that discharges the document. When reserved originals are set on both reserved original tables 9 and 10, reserved copying is performed in the order of upper row → lower row. 11,12
is a document detection sensor placed on each reserved document table. The original detection sensors 11 and 12 are composed of light emitters and receivers, and detect the set of originals by receiving reflected light from a reflective sheet (not shown) provided on the reserved original table. That is, when a reserved original is set, the amount of light received by the sensor decreases, and thereby the setting of the original is detected. Reference numeral 18 denotes a paper feed roller that feeds the reserved original on the original table.

A sorter 14 is attached to the main body 1 of the copying machine. The sorter 14 has a copy stage bin 15, and a reservation-only bin 16 is provided at the bottom stage. Copy sheets for reserved copying are discharged into a bin 16. Reference numeral 17 denotes a bin empty sensor for detecting copy sheets in the bin 16.

Figure 4 shows the ADF operation section. The ADF operation section 31 includes an upper reservation key 32 and a lower reservation key 33.
and a reservation memory key 34 are provided. The upper reservation key 32 and the lower reservation key 33 are respectively provided with document table reservation display devices 35 and 36 for displaying the reserved document table. Reference numerals 37 and 38 are paper feed cassette reservation display devices for displaying reserved upper or lower paper feed cassettes. Reference numeral 39 indicates a display that indicates that the document has not been set, and reference numeral 40 indicates a display that indicates that the document has been left behind when the document remains on the document table after scheduled copying has been completed.

To make a reservation, first press the reservation key on an empty reservation manuscript table. Then, the document setting guide display 39 blinks to prompt the user to set the document. At this time, the document table reservation display 35 or 36 of the reserved document table selected at this time also blinks. Next, when you set the reserved original on the reserved original table, the original setting guidance display disappears.
Next, copy conditions such as the number of copies of the original, copy paper size, density, etc. are input, and the reservation memory key 34 is pressed. This key operation ends the reservation setting, and the reservation display of the selected reservation manuscript table changes from flashing to lit. At this time, if the bin empty sensor 17 detects that the reservation bin 16 is not empty, the reservation setting will not be completed even if the reservation memory key 34 is pressed.

A human body detection sensor 19 is provided on the front side of the copying machine main body 1, as shown in FIG. The human body detection sensor 19 is composed of a pyroelectric infrared sensor including a pyroelectric detector 20, as shown in FIG. For example, the wavelength from the surface of the human body at a temperature of 30°C is
Infrared radiation with a peak wavelength of 10 μm is emitted. The pyroelectric detector 20 is a detector that is highly sensitive to this peak wavelength. 21 is a condensing mirror for condensing infrared rays L emitted from the human body over a wide viewing angle. FIG. 7 shows a human body detection circuit using the human body detection sensor 19. The output of the pyroelectric detector 20 is amplified by the first stage amplifier 22, and the DC component is further cut off and introduced into the amplifier 23. The output of the amplifier 23 is input to third and fourth stage comparators 24 and 25. The output of the amplifier 23 only changes from a state in which a human body is detected to a state in which a human body is not detected, or vice versa.
It deviates from the intermediate potential only in an unsteady state and returns to the intermediate potential in the steady state. When the output of the amplifier 23 deviates from the intermediate potential, the third and fourth stage comparators 24 and 2
5 turns on, turning on the output transistor 26.
By turning on the output transistor 26, the controller CPU 27 of the copying machine is notified that the human body, that is, the user has approached or left.

Next, the operation when performing reserved copying will be explained with reference to FIG.

Assume that a reserved original is set on the reserved original table and reserved copying is set. First, step n
1 (hereinafter, step ni is simply referred to as ni), it is determined whether normal copying is being performed or whether normal copying is starting. If a normal copy is to be executed, n2 executes the copy process. When normal copying is not being performed, it is determined in n3 whether reserved copy is set. When there is a reservation, steps n4 and n5 start a built-in timer (not shown) in the CPU 27 and determine whether a user approaching the copying machine is detected before the timer times up. When the human body detection sensor 19 detects the approach of the user, it is determined that normal copying is being used, and the state returns to the copy operation acceptance state n1. When the approach of a human body is not detected even after the timer expires, reserved copying is started n6. If the human body detection sensor 19 detects the approach of a human body even after the reservation copy is started, the execution of the reservation copy is interrupted and the process returns to the normal copy operation acceptance state n1 n7. As a result, interrupts for normal copying are enabled even when reserved copying is being executed, and interrupt copying is executed with priority over reserved copying.
