Abstract
Abstract An image processing apparatus has a reader capable of dynamic and static reading, a printer, an original feed unit, and a control circuit including a microcomputer. When image data of an original larger than a standard size is fed, the data is partially read by dynamic reading and recorded, and thereafter the remaining data is read by static reading and recorded.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
75 words
An image processing apparatus comprising: reading means operated in a first mode for reading image data while an original is being moved and a second mode for reading the image data by scanning while the original is stopped at a predetermined position; memory means for storing the image data read by said reading means; and selecting means for selecting one of the first and second modes in accordance with a state of said memory means.
Claim 2
Dependent Claim
75 words
An image processing apparatus comprising: reading means operated in a first mode for reading image data while an original is being moved and a second mode for reading the image data by scanning while the original is stopped at a predetermined position; memory means for storing the image data read by said reading means; and selecting means for selecting one of the first and second modes in accordance with a state of said memory means.
Claim 3
Dependent Claim
27 words
An apparatus according to claim 1, wherein said selecting means selects the second mode when said memory means overflows during image data reading in the first mode.
Claim 4
Dependent Claim
28 words
An apparatus according to claim 2, wherein the image data read in the first mode and stored in said memory means is deleted when said memory means overflows.
Claim 5
Dependent Claim
34 words
An apparatus according to claim 3, wherein said reading means reads the image data of the original which is read and subjected to overflow of said memory means after the image data is deleted.
Claim 6
Dependent Claim
31 words
An apparatus according to claim 1, wherein said reading means comprises original feeding means for feeding the original and scanning means which reciprocates to scan the original at the predetermined position.
Claim 7
Dependent Claim
45 words
An apparatus according to claim 5, wherein said scanning means is fixed at a dynamic reading position in the first mode so as to cause said original feeding means to feed the original in such a manner that the original passes by said scanning means.
Claim 8
Dependent Claim
23 words
An apparatus according to claim 5, wherein said scanning means passes by the original stopped at the predetermined position in the second mode.
Claim 9
Dependent Claim
61 words
An apparatus according to claim 6, wherein said feeding means feeds the original in a static reading position to read the image data from the original by reciprocating said scanning means in the second mode, the dynamic reading position in the first mode and the static reading position in the second mode being located on a single platen of recording means.
Claim 10
Dependent Claim
33 words
An apparatus according to claim 5, wherein said scanning means comprises image pick-up means for converting an optical signal to an electrical signal, the image data being read by said image pick-up means.
Claim 11
Dependent Claim
91 words
An image processing apparatus comprising: reading means operated in a first mode for reading image data while an original is being moved and a second mode for reading the image data by scanning while the original is stopped at a predetermined position; recording means for recording an image on a recording medium in accordance with the image data read by said reading means; and controlling means for switching from the first mode to the second mode in response to a specific conditional signal during image data reading in the first mode.
Claim 12
Dependent Claim
91 words
An image processing apparatus comprising: reading means operated in a first mode for reading image data while an original is being moved and a second mode for reading the image data by scanning while the original is stopped at a predetermined position; recording means for recording an image on a recording medium in accordance with the image data read by said reading means; and controlling means for switching from the first mode to the second mode in response to a specific conditional signal during image data reading in the first mode.
Claim 13
Dependent Claim
18 words
An apparatus according to claim 10, wherein the specific conditional signal comprises a signal representing an original size.
Claim 14
Dependent Claim
89 words
An apparatus according to claim 11, wherein said controlling means causes said reading means to read a portion of the image data and causes said recording means to record partial image data on the recording medium and thereafter causes said reading means to read a remaining portion of the image data in the second mode and causes said recording means to record remaining image data on the recording medium when a signal representing that the original size is larger than a standard size is received by said controlling means.
Claim 15
Dependent Claim
34 words
An apparatus according to claim 12, wherein said recording means records the partial image data read in the first mode and the remaining image data read by the second mode on different recording media.
Claim 16
Dependent Claim
25 words
An apparatus according to claim 13, wherein the image data read in the first mode partially overlaps the image data read in the second mode.
Claim 17
Dependent Claim
26 words
An apparatus according to claim 10, wherein the specific conditional signal comprises a signal representing a feed failure of the recording medium in said recording means.
Claim 18
Dependent Claim
31 words
An apparatus according to claim 10, wherein said reading means comprises original feeding means for feeding the original and scanning means which reciprocates to scan the original at the predetermined position.
Claim 19
Dependent Claim
45 words
An apparatus according to claim 16, wherein said scanning means is fixed at a dynamic reading position in the first mode so as to cause said original feeding means to feed the original in such a manner that the original passes by said scanning means.
Claim 20
Dependent Claim
23 words
An apparatus according to claim 16, wherein said scanning means passes by the original stopped at the predetermined position in the second mode.
Claim 21
Dependent Claim
62 words
An apparatus according to claim 17, wherein said feeding means feeds the original in a static reading position to read the image data from the original by reciprocating said scanning means in the second mode, the dynamic reading position in the first mode and the static reading position in the second mode being located on a single platen of said recording means.
Claim 22
Dependent Claim
27 words
An apparatus according to claim 19, wherein the dynamic reading position is located at an upstream side of the static reading position along an original feed direction.
Claim 23
Dependent Claim
33 words
An apparatus according to claim 16, wherein said scanning means comprises image pick-up means for converting an optical signal to an electrical signal, the image data being read by said image pick-up means.
