Abstract
Abstract A storage chamber for temporally storing elongate web is provided between exposure device for imagewisely exposing the elongate web and developing device. After the amount of web in the storage chamber has reached a preset amount, the web is fed from the storage chamber to the developing device, and feeding device is stopped when development of the trailing end of the final exposed section on the web has been terminated after the feed of the web to the developing device has been started.

Claim 1
Independent Claim
180 words
A recording apparatus for recording an image on an elongate web comprising: exposure means for exposing an image on said web; developing means for developing the exposed web; a web storage chamber disposed between said exposure means and said developing means for storing in loop form the web fed from said exposure means; feeding means for feeding the web from said web storage chamber to said developing means; operating means for initiating operation of said developing means; timer means arranged for actuation when the amount of web in said web storage chamber has reached a predetermined amount so as to generate a timing signal a predetermined interval after actuation, wherein said timer means is reset to prevent generation of the timing signal if said operating means initiates opertion of said developing means before passage of the predetermined interval; and control means for controlling said feeding means such that the web in said web storage chamber is fed to said developing means either in response to the initiation of operation of said developing means or in response to the timing signal.
