Abstract
Abstract A photosensitive material such as film is conveyed while the widthwise edges thereof are guided by width guides. The width guides have an adjusting part such as a screw to adjust the position thereof when the width of the photosensitive material changes. The adjusting part, even when the width dimension of the sensitized material does not change, is driven at a specified interval such as every few hours to remove a precipitate such as a developer which is deposited on the adjusting part.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
97 words
A method of operating a conveyor rack which guides and conveys photosensitive material within a treatment area and which is used for an automatic developing apparatus in which the position of width guides for guiding the widthwise edges of said photosensitive material is adjustable by drive means according to the width of said photosensitive material, comprising the following step: driving said width guides with said drive means within a given position-adjusting range at a specified interval to remove a precipitate which has precipitated out of a treatment liquid and which has been deposited on said drive means.
Claim 2
Independent Claim
97 words
A method of operating a conveyor rack which guides and conveys photosensitive material within a treatment area and which is used for an automatic developing apparatus in which the position of width guides for guiding the widthwise edges of said photosensitive material is adjustable by drive means according to the width of said photosensitive material, comprising the following step: driving said width guides with said drive means within a given position-adjusting range at a specified interval to remove a precipitate which has precipitated out of a treatment liquid and which has been deposited on said drive means.
Claim 3
Dependent Claim
24 words
A method of operating a conveyor rack as in claim 1, wherein said driving step includes driving said width guides at specified time intervals.
Claim 4
Dependent Claim
20 words
A method of operating a conveyor rack as in claim 1, further comprising the step of heating said treatment liquid.
Claim 5
Dependent Claim
33 words
A method of operating a conveyor rack as in claim 1, wherein said driving step is conducted after a stop signal for terminating the operation of said automatic developing apparatus has been generated.
Claim 6
Dependent Claim
42 words
A method of operating a conveyor rack as in claim 1, wherein said driving step includes driving said width guides for the entire distance of a previously specified position adjusting range, and then returning said width guides to the original position thereof.
Claim 7
Dependent Claim
44 words
A method of operating a conveyor rack as in claim 1, wherein said driving step includes driving said width guides from a position corresponding to a minimum width of said photosensitive material to be conveyed to a position corresponding to a maximum width thereof.
Claim 8
Dependent Claim
60 words
A method of operating a conveyor rack as in claim 6, wherein said driving step includes driving said width guides, whose home position is made to be said position corresponding to a maximum width, to said position corresponding to a minimum width at the end of each said specified interval and thereafter returning said width guides to said home position.
Claim 9
Dependent Claim
26 words
A method of operating a conveyor rack as in claim 1, further comprising the step of detecting the position of said width guides using limit switches.
Claim 10
Dependent Claim
30 words
A method of operating a conveyer rack as in claim 1, further comprising the step of sounding an alarm if said width guides move out of said position adjusting range.
Claim 11
Dependent Claim
28 words
A method of operating a conveyer rack as in claim 1, wherein said driving step includes driving said width guides a plurality of times at said specified interval.
Claim 12
Dependent Claim
31 words
A method of operating a conveyer rack as in claim 1, wherein said driving step includes driving said width guides every time a specified length of photosensitive material has been treated.
Claim 13
Dependent Claim
31 words
A method of operating a conveyer rack as in claim 1, wherein said driving step includes driving said width guides every time a specified area of photosensitive material has been treated.
Claim 14
Dependent Claim
29 words
A method of operating a conveyer rack as in claim 1, wherein said driving step includes driving said width guides beyond said position adjusting range at said specified interval.
Claim 15
Dependent Claim
183 words
A conveyor rack which guides and conveys photosensitive material within a treatment tank, comprising; a rack body, part of which is immersed in said treatment tank; holding rollers supported by said rack body, for holding and conveying said sensitized material through a treatment liquid; a roller drive shaft having one end connectd to said holding roller and the other end extending out of said treatment liquid to serve as a drive-source connecting part; a manual roller-turning handle mounted on said rack body and connected to said one end of said roller drive shaft extending out of said treatment liquid; width guides, supported by said rack body, for guiding the widthwise edges of said photosensitive material through said treatment liquid, and whose positions are adjustable according to the width of said photosensitive material; a width guide drive shaft having one end connected to said width guides and the other end extending above the level of said treatment liquid; and a manual width guide adjusting handle connected to said one end of said width guide drive shaft extending above the level of said treatment liquid.
Claim 16
Dependent Claim
183 words
A conveyor rack which guides and conveys photosensitive material within a treatment tank, comprising; a rack body, part of which is immersed in said treatment tank; holding rollers supported by said rack body, for holding and conveying said sensitized material through a treatment liquid; a roller drive shaft having one end connectd to said holding roller and the other end extending out of said treatment liquid to serve as a drive-source connecting part; a manual roller-turning handle mounted on said rack body and connected to said one end of said roller drive shaft extending out of said treatment liquid; width guides, supported by said rack body, for guiding the widthwise edges of said photosensitive material through said treatment liquid, and whose positions are adjustable according to the width of said photosensitive material; a width guide drive shaft having one end connected to said width guides and the other end extending above the level of said treatment liquid; and a manual width guide adjusting handle connected to said one end of said width guide drive shaft extending above the level of said treatment liquid.
Claim 17
Dependent Claim
38 words
A conveyor rack for conveying photosensitive material as in claim 14, wherein portions at one end of said roller drive shaft and of said width guide shaft vertically penetrate and extend beyond the surface of said treatment liquid.
Claim 18
Dependent Claim
62 words
A conveyor rack for conveying photosensitive material as in claim 14, wherein said width guides are arranged such that width guide bodies corresponding to respective widthwise edges of said photosensitive material are driven by a combination of screws and nuts in a widthwise direction, that is, transversely across said photosensitive material and at a night angle to the direction of conveyance thereof.
Claim 19
Dependent Claim
53 words
A conveyor rack for conveying a photosensitive material as in claim 15, wherein said roller drive shaft and said width guide shaft stand upright and extend above the surface of said treatment liquid and said handles are connected to the respective upper ends of said roller drive shaft and said width guide shaft.
