Abstract
Abstract A facsimile apparatus has a single conveying roller in it, above which an image sensor is set and below which a printing head is set. Pressing pins are set respectively near the upper and lower ends of components supporting the conveying roller to freely rotate. In transmission, the lower pressing pins keep away the printing head from the conveying roller and the image sensor presses an original document onto the conveying roller. In reception, the upper pressing pins keep away the image sensor from the conveying roller and the printing head presses the recording paper onto the conveying roller. In this way, structure of the facsimile apparatus is simplified.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
145 words
An image data processing apparatus comprising: conveying means for conveying an original document in a first direction and for conveying recording paper in the first direction; reading means movable in directions perpendicular to the conveying direction of the original document and the recording paper, for being pressed against the original document and reading and outputting image data from the original document; printing means movable in directions perpendicular to the conveying direction of the recording paper, for being pressed against the recording paper and printing image data onto recording paper; and plural working members, operatively contactable to the reading means and the printing means, for releasing pressure to move one of the reading means and the printing means away from the conveying means and for simultaneously contacting and applying pressure to move the other of the reading means and the printing means toward the conveying means.
Claim 2
Dependent Claim
145 words
An image data processing apparatus comprising: conveying means for conveying an original document in a first direction and for conveying recording paper in the first direction; reading means movable in directions perpendicular to the conveying direction of the original document and the recording paper, for being pressed against the original document and reading and outputting image data from the original document; printing means movable in directions perpendicular to the conveying direction of the recording paper, for being pressed against the recording paper and printing image data onto recording paper; and plural working members, operatively contactable to the reading means and the printing means, for releasing pressure to move one of the reading means and the printing means away from the conveying means and for simultaneously contacting and applying pressure to move the other of the reading means and the printing means toward the conveying means.
Claim 3
Dependent Claim
57 words
The image data processing apparatus of claim 1, wherein said conveying means includes a roller located between the reading means and the printing means, for being pressed against one of the reading and printing means, through the original document and recording paper, respectively, upon the one of the reading and printing means being moved toward the roller.
Claim 4
Dependent Claim
155 words
The image data processing apparatus of claim 2, wherein end components, freely supporting the roller for rotation and conveying, are located at axial ends of the roller and are operatively connected to the plural working members, the plural working members including first working pins, for applying and releasing pressure to the reading means and second working pins, for applying and releasing pressure to the printing means, the first working pins being set at locations where the first working pins are pressed against end released from the reading means, corresponding to a first state of predefined angular motion of the end components and a second state in a reverse direction of the first state, respectively, and the second working pins being set at locations where the second working pins are released from and pressed against the printing means, corresponding to the first state and the second state of predefined angular motion of the end components, respectively.
Claim 5
Dependent Claim
33 words
The image data processing apparatus of claim 3, wherein the end components are operatively connected to a driving means for driving end components in the first and second states of angular motion, respectively.
