Abstract
The copying machine permits a selective use of either a single sheet original, or a file original such as a book, and in which an original is moved by means of rollers for scanning an image thereof. A plurality of drive rollers are disposed on the under side of a path of movement of an original to be copied, whereas mating driven rollers are mounted on a movable frame so that they can be retracted from their normal position when a file original is used. The frame is manually moved to the retracted position without substantial change in its posture, thereby permitting an operator to easily operate the frame. After the frame is retracted, a file original may be placed on a transparent sheet member which is arranged to be fed on the drive roller so as to be moved thereby for scanning.
Claims7
A copying machine, which permits a selective use of either a single sheet original or a file original comprising:
- a. main body
- b. a plurality of drive rollers disposed on the underside of a path of movement of an image bearing surface of an original to be copied with their axes extending transversely of said path, and mounted on said body for rotation,
- c. marginal driven rollers each mounted on said body on the other side of said path for cooperation with end portions of a respective drive rollers,
- d. a transparent sheet member arranged to be fed between said drive rollers and said marginal driven rollers from an inlet of said path, thereby to be moved along said path while receiving a file original thereon,
- e. intermediate driven rollers, each engageable with the remaining intermediate portions of said drive rollers on the other side of said path, to form nips therebetween for moving a single sheet original fed from said path inlet,
- f. frame means, mounting said intermediate driven rollers thereon, movable between a first position, in which said intermediate driven rollers engage with respective drive rollers, and a second position, in which it is closely juxtaposed to the region in which said drive rollers are disposed along a direction parallel to said path while its top extremity is below an extension of said path,
- g. guide means guiding the movement of said frame means between said first and second positions without substantial change in the orientation of said frame means,
- h. handle means provided at a front end of said frame means corresponding to said path inlet to be gripped by an operator to manually move said frame means between said first and second positions, and
- i. means for scanning an image of an original during its movement along said path.
