Claim 8

A copying device having a slit-exposure system comprising: a housing; a copy stand on the upper portion of said housing and means for reciprocatingly moving said stand; means for storing, feeding and charging photosensitive material; means for transferring said photosensitive material between said feeding means and charging means; means for synchronously moving said copy stand and the photosensitive material; means for illuminating the original placed on said copy stand; a stationary optical system within the housing for introducing the light image of the illuminated original to the exposure station, where the light image of the illuminated original is cast upon the photosensitive material; means for developing the photosensitive material; said means for synchronously moving said copy stand and the photosensitive material comprise: means for normally stopping said copy stand at the terminal position of its normal movement and initiating reverse movement; means for feeding the photosensitive material at a predetermined position in the reverse movement of said copy stand; and means for synchronously driving the photosensitive material to the slit-exposure position when said copy stand arrives at the illuminating position.

Claim 9

A copying device having a slit-exposure system comprising: a housing; a copy stand on the upper portion of said housing and means for reciprocatingly moving said stand; means for storing, feeding and charging photosensitive material; means for transferring said photosensitive material between said feeding means and charging means; means for synchronously moving said copy stand and the photosensitive material; means for illuminating the original placed on said copy stand; a stationary optical system within the housing for introducing the light image of the illuminated original to the exposure station, where the light image of the illuminated original is cast upon the photosensitive material; means for developing the photosensitive material; said means for synchronously moving said copy stand and the photosensitive material comprise: means for normally stopping said copy stand at the terminal position of its normal movement and initiating reverse movement; means for feeding the photosensitive material at a predetermined position in the reverse movement of said copy stand; and means for synchronously driving the photosensitive material to the slit-exposure position when said copy stand arrives at the illuminating position.

Claim 10

The copying device as claimed in claim 6, wherein said means for normally stopping said copy stand is moveable, whereby the terminal position of said copy stand is adjustable in accordance with the size of the original.

Claim 11

The copying device as claimed in claim 7, wherein said moveable stopping means is mounted on said copy stand.

Claim 12

The copying device as claimed in claim 5, wherein said drum rotating means includes means for absorbing the shock produced when reverse movement of said copy stand is initiated.

Claim 13

A copying device having a slit-exposure system comprising: a housing; a copy stand on the upper portion of said housing and means for reciprocatingly moving said stand; means for storing, feeding and charging photosensitive material; means for transferring said photosensitive material between said feeding means and charging means; means for synchronously moving said copy stand and the photosensitive material; means for illuminating the original placed on said copy stand; a stationary optical system within the housing for introducing the light image of the illuminated original to the exposure station, where the light image of the illuminated original is cast upon the photosensitive material; means for normally stopping said copy stand at the start position of its normal movement and initiating normal movement responsive to the arrival of the photosensitive material in the slit-exposure position; means for adjusting the travelling distance of the normal movement of said copy stand in accordance with the size of the original, said travelling distance adjusting means being mounted on said copy stand; and means for developing the photosensitive material.
