Abstract
Abstract Image data transmitted through a line is recorded by conducting main scan by moving a recording head having a plurality of recording elements arranged in a sub-scan direction relative to a record medium in a main scan direction. A resolution in the main scan direction may be set by a user to a desired value through a switch, and the image data is thinned at a predetermined rate in accordance with the selected resolution and the speed to move the record head is increased.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
152 words
An image communication apparatus capable of recording an image on a record medium at a first resolution in accordance with image data transmitted through a line by record-scanning by using record means having a plurality of recording elements arranged at a predetermined recording density, comprising: selection means for selecting a resolution of the image to be recorded by said record means; supply means for dropping the image data at a predetermined rate when a second resolution lower than said first resolution of the image to be recorded by said record means is selected and supplying the dropped image data to said record means; and scan means for conducting the record-scanning of said record means at a high speed in accordance with said second resolution, wherein said scan means conducts the record-scanning at the second resolution at a speed of (the first resolution)/(the second resolution) times of the speed in the first resolution.
Claim 2
Dependent Claim
152 words
An image communication apparatus capable of recording an image on a record medium at a first resolution in accordance with image data transmitted through a line by record-scanning by using record means having a plurality of recording elements arranged at a predetermined recording density, comprising: selection means for selecting a resolution of the image to be recorded by said record means; supply means for dropping the image data at a predetermined rate when a second resolution lower than said first resolution of the image to be recorded by said record means is selected and supplying the dropped image data to said record means; and scan means for conducting the record-scanning of said record means at a high speed in accordance with said second resolution, wherein said scan means conducts the record-scanning at the second resolution at a speed of (the first resolution)/(the second resolution) times of the speed in the first resolution.
Claim 3
Dependent Claim
19 words
An image communication apparatus according to claim 1, wherein said selection means sets any resolution in the record-scan direction.
Claim 4
Dependent Claim
28 words
An image communication apparatus according to claims 1 or 2, wherein said scan means conducts the record-scanning by relatively reciprocally moving said record means to said record medium.
Claim 5
Dependent Claim
29 words
An apparatus according to claim 1, wherein said selection means selects the resolution of the image to be recorded in accordance with a resolution of the image data transmitted.
Claim 6
Dependent Claim
28 words
An apparatus according to claim 1, wherein said selection means selects the resolution of the image to be recorded in accordance with a remaining amount of recording material.
Claim 7
Dependent Claim
12 words
An apparatus according to claim 5, wherein said recording material is ink.
Claim 8
Dependent Claim
28 words
An apparatus according to claim 1, wherein said selection means selects the resolution of the image to be recorded in accordance with a remaining amount of recording agent.
Claim 9
Dependent Claim
40 words
An apparatus according to claim 1, further comprising memory means for storing the image data transmitted, wherein said selection means selects the resolution of the image to be recorded in accordance with a remaining memory capacity of said memory means.
Claim 10
Dependent Claim
40 words
An apparatus according to claim 1, further comprising memory means for storing the image data transmitted, wherein said selection means selects the resolution of the image to be recorded in accordance with a remaining memory capacity of said memory means.
Claim 11
Dependent Claim
18 words
An image communication apparatus according to claim 3, wherein said record means discharges ink to record the image.
Claim 12
Dependent Claim
27 words
An image communication apparatus according to claim 10, wherein said record means discharges the ink by causing a state change in the ink by using thermal energy.
Claim 13
Dependent Claim
26 words
An image communication apparatus according to claims 1, 2, 4, 5, 6, 7, 8 or 9, wherein said record means discharges ink to record the image.
Claim 14
Dependent Claim
27 words
An image communication apparatus according to claim 12, wherein said record means discharges the ink by causing a state change in the ink by using thermal energy.
