Abstract
Abstract A copier including a document transporting carriage movable from a home position through a document illuminating station and back to the home position, and including instrumentalities for energizing the copier for a predetermined time interval to copy a document on the carriage is provided with timing apparatus for disabling the energizing instrumentalities. The timing apparatus includes a switch operatively connected to the energizing instrumentalities for enabling and disabling the same. The switch is normally operative for enabling the energizing instrumentalities and is actuatable to disable the instrumentalities. In addition, an actuating device cooperative with the carriage and the switch is provided for actuating the switch after a predetermined time interval if the carriage is not moved from the home position, or back to the home position, during the aforesaid predetermined time interval.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
118 words
In a copier including a document transporting carriage movable from a home position through a document illuminating station and back to said home position, and including means for energizing said copier for a predetermined time interval to copy a document on said carriage, timing apparatus for disabling said energizing means comprising: a. switching means operatively connected to said energizing means for enabling and disabling said energizing means, said switching means being normally operative for enabling said energizing means and being actuatable to disable said energizing means; and b. means coopertive with said carriage and said switching means for actuating said switching means if said carriage is not moved back to said home position during said predetermined time interval.
Claim 2
Dependent Claim
118 words
In a copier including a document transporting carriage movable from a home position through a document illuminating station and back to said home position, and including means for energizing said copier for a predetermined time interval to copy a document on said carriage, timing apparatus for disabling said energizing means comprising: a. switching means operatively connected to said energizing means for enabling and disabling said energizing means, said switching means being normally operative for enabling said energizing means and being actuatable to disable said energizing means; and b. means coopertive with said carriage and said switching means for actuating said switching means if said carriage is not moved back to said home position during said predetermined time interval.
Claim 3
Dependent Claim
91 words
The apparatus according to claim 1, wherein said interval is a first predetermined time interval, said actuating means including a timing motor and an arm connected to said motor for rotation thereby, said arm having a rest position wherein said arm is disposed out of engagement with said switching means, and said arm being rotatable out of said rest position and into engagement with said switching means by said timing motor for actuating said switching means at the end of a second predetermined time interval ending after said first predetermined interval.
Claim 4
Dependent Claim
31 words
The apparatus according to claim 1, wherein said energizing means includes a print switch, and said switching means including a normally closed switch electrically connected in series with said print switch.
Claim 5
Dependent Claim
53 words
The apparatus according to claim 2, wherein said carriage includes a stop extending therefrom and movable thereby into engagement with said arm for normally returning said arm to said rest position during said first predetermined time interval, thereby to prevent said arm from actuating said switching means during said second predetermined time interval.
Claim 6
Dependent Claim
29 words
The apparatus according to claim 2, wherein said timing motor is energized when said copier is energized, and said second time interval is longer than said first time interval.
Claim 7
Dependent Claim
37 words
The apparatus according to claim 4, wherein said timing motor includes clutch through which said arm is rotated by said timing motor, said clutch being adapted to slip when said arm is returned to said rest position.
Claim 8
Dependent Claim
151 words
In a copier including means for energizing said copier for copying a document during a copying cycle, timing apparatus for disabling said energizing means, comprising: a. switching means operatively connected to said energizing means for enabling and disabling said energizing means, said switching means being normally operative for enabling said energizing means and being actuatable to disable said energizing means; and b. means cooperative with said switching means for actuating said switching means in a predetermined time interval after energizing said copier, said actuating means including a timing motor and an arm connected to said motor for rotation thereby, said arm having a rest position wherein said arm is disposed out of engagement with said switching means, and said arm being rotatable out of said rest position and into engagement with said switching means by said timing motor for actuating said switching means at the end of said predetermined time interval.
Claim 9
Dependent Claim
151 words
In a copier including means for energizing said copier for copying a document during a copying cycle, timing apparatus for disabling said energizing means, comprising: a. switching means operatively connected to said energizing means for enabling and disabling said energizing means, said switching means being normally operative for enabling said energizing means and being actuatable to disable said energizing means; and b. means cooperative with said switching means for actuating said switching means in a predetermined time interval after energizing said copier, said actuating means including a timing motor and an arm connected to said motor for rotation thereby, said arm having a rest position wherein said arm is disposed out of engagement with said switching means, and said arm being rotatable out of said rest position and into engagement with said switching means by said timing motor for actuating said switching means at the end of said predetermined time interval.
Claim 10
Dependent Claim
31 words
The apparatus according to claim 7, wherein said energizing means includes a print switch, and said switching means including a normally closed switch electrically connected in series with said print switch.
Claim 11
Dependent Claim
27 words
The apparatus according to claim 7, wherein said timing motor is energized when said copier is energized, and said time interval is longer than said copying cycle.
Claim 12
Dependent Claim
38 words
The apparatus according to claim 7, wherein said timing motor includes a clutch through which said arm is rotated by said timing motor, said clutch being adapted to permit said arm to be returned to said rest position.
