Abstract
Abstract When a print switch is pressed, the color of the switch changes from green to orange. A wait indication prohibiting removal of an original placed on a platen glass is turned on. When reading of original images by an image reader is finished, the wait indication is turned off, permitting the removal of the original. Meanwhile, the color of the print switch is kept as it is until the end of image formation on a paper. The color of the print switch is turned into green when the image formation is finished, and the copying machine is returned to a stand-by state. Therefore, the next original can be set before the end of image formation, and the copying operation can be facilitated.

Claim 1
Independent Claim
97 words
A copying machine, comprising: a platen on which an original is placed; image reading means having a one-dimensional image sensor and scanning means for reading images of the original placed on said platen; memory means for storing image data corresponding to the images read by said image reading means; image forming means for forming images based on the image data stored by said memory means; first indicating means for indicating that said image reading means is carrying out reading operation; and second indicating means for indicating that said image forming means is carrying out image forming operation.
Claim 2
Dependent Claim
97 words
A copying machine, comprising: a platen on which an original is placed; image reading means having a one-dimensional image sensor and scanning means for reading images of the original placed on said platen; memory means for storing image data corresponding to the images read by said image reading means; image forming means for forming images based on the image data stored by said memory means; first indicating means for indicating that said image reading means is carrying out reading operation; and second indicating means for indicating that said image forming means is carrying out image forming operation.
Claim 3
Dependent Claim
78 words
A copying machine according to claim 1, further comprising mode designating means for designating a mode in which said image forming means are activated a plurality of times based on the image data stored in said memory means, wherein said image reading means is activated once in response to a designating output of said mode designating means, and indication of said first indicating means is released after the end of the reading operation of said image reading means.
Claim 4
Dependent Claim
64 words
A copying machine according to claim 1, further comprising: area designating means for designating a plurality of areas of the original placed on said platen; and control means for controlling said memory means such that only image data corresponding to the areas designated by said area designating means out of the images read by said image reading means are stored by said memory means.
Claim 5
Dependent Claim
122 words
A copying machine according to claim 3, wherein said area designating means comprises at least two index members arranged on an end portion of said platen along a scanning direction of said scanning means, said members movable in said scanning direction, and detecting means for detecting a position of each of said index members; and said control means responsive to a detection from said detecting means, controls said memory means such that image data of the original included in a scanning area scanned by said scanning means sandwiched by two of said index members are removed, and image data of the original included in an area scanned before said sandwiched area and an area scanned after said sandwiched area are continuously stored.
Claim 6
Dependent Claim
42 words
A copying machine according to claim 4, wherein each of said index members has a mark on the rear surface, said scanning means scanning said original as well as said mark for projecting an image of said mark to said image sensor.
Claim 7
Dependent Claim
98 words
A copying machine, comprising: a platen on which an original is placed; image reading means for reading images of the original placed on said platen; memory means for storing image data read by said image reading means; image forming means for forming images based on the image data stored in said memory means; prohibiting means for prohibiting, when said image reading means in an activated state, removal of the original placed on said platen; and releasing means for releasing, when reading by said image reading means is finished, prohibition of removal of the original by said prohibiting means.
Claim 8
Dependent Claim
98 words
A copying machine, comprising: a platen on which an original is placed; image reading means for reading images of the original placed on said platen; memory means for storing image data read by said image reading means; image forming means for forming images based on the image data stored in said memory means; prohibiting means for prohibiting, when said image reading means in an activated state, removal of the original placed on said platen; and releasing means for releasing, when reading by said image reading means is finished, prohibition of removal of the original by said prohibiting means.
Claim 9
Dependent Claim
128 words
A copying machine according to claim 6, further comprising instructing switch for instructing activation of said image reading means; first indicating means capable of switchably indicating a first state in which said image forming means is in active and a second state in which said image forming means is not in active; and second indicating means capable of switchably indicating a first state in which said prohibiting means is in active and a second state in which said prohibiting means is not in active; wherein said first and second indicating means, responsive to an instruction output of said instructing switch, change from the second state to the first state, said releasing means changes the indication of said second indicating means from said second state to said first state.
Claim 10
Dependent Claim
31 words
A copying machine according to claim 7, wherein said first indicating means changes from said first state to said second state when image formation by said image forming means is finished.
Claim 11
Dependent Claim
57 words
A copying machine according to claim 7, further comprising mode designating means for designating a mode in which said image forming means is activated a plurality of times based on the image data stored in said memory means; wherein said image reading means is activated once in response to a designation output from said mode designating means.
