Abstract
Abstract A checkwriter incorporating an accumulator and differentially settable sectors for entering amounts to be printed on checks and for subtracting such amounts from the accumulator as well as for adding into the accumulator amounts representing deposits in the user''s bank account. The checkwriter is automatically locked up when an amount is overdrawn from the accumulator or when an amount greater than a predetermined amount is entered. The checkwriter also incorporates control means which are normally set to cause subtract operations but which may be selectively set to cause an add operation and which are automatically returned to subtract controlling condition following an add operation.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
81 words
In a checkwriter having an accumulator; printing mechanism; means including differentially movable sectors for setting up amounts to be printed; control mechanism settable in a first condition for causing said sectors to subtract an amount from said accumulator; the combination of a member movable out of a home position by any of said sectors upon setting up an amount; and means controlled by said accumulator upon reaching an overdrafted condition for blocking said member from moving out of said home position.
Claim 2
Dependent Claim
81 words
In a checkwriter having an accumulator; printing mechanism; means including differentially movable sectors for setting up amounts to be printed; control mechanism settable in a first condition for causing said sectors to subtract an amount from said accumulator; the combination of a member movable out of a home position by any of said sectors upon setting up an amount; and means controlled by said accumulator upon reaching an overdrafted condition for blocking said member from moving out of said home position.
Claim 3
Dependent Claim
83 words
The combination according to claim 1 comprising cyclically operable drive means wherein said last-mentioned means comprises means for sensing an overdraft condition of said accumulator; means controlled by said sensing means upon sensing an overdraft condition for blocking said member form moving out of said home position; and means responsive to said drive means when out of full cycle position for rendering said sensing means inoperative and responsive to said drive means when in full cycle position for rendering said sensing means operative.
Claim 4
Dependent Claim
90 words
The combination according to claim 1 wherein said last-mentioned means comprises sensing means for sensing an overdraft condition of said accumulator; means controlled by said sensing means upon sensing an overdraft condition for blocking said member from moving out of said home position; cyclically operable means having a full cycle position for operating said printing mechanism; and means operable during operation of said sectors for rendering said sensing means ineffective and operable substantially at the end of a cycle of said cyclically operable means for rendering said sensing means effective.
Claim 5
Dependent Claim
26 words
The combination according to claim 3 wherein said last-mentioned means maintains said sensing means operable when said cyclically operable means is in said full cycle position.
Claim 6
Dependent Claim
50 words
The combination according to claim 1 wherein said control mechanism is selectively settable in a secoNd condition to cause said sectors to add an amount set up in said sectors into said accumulator, and means responsive to operation of said checkwriter for resetting said control mechanism in said first condition.
Claim 7
Dependent Claim
68 words
The combination according to claim 1 wherein said control mechanism is selectively settable into a second condition to cause said sectors to add an amount set up in said sectors into said accumulator; latch means for maintaining said control mechanism in said second condition; spring means for returning said control mechanism to said first condition; and means responsive to operation of said checkwriter for releasing said latch means.
Claim 8
Dependent Claim
34 words
The combination according to claim 5 comprising means controlled by said accumulator when the highermost order thereof registers a predetermined positive amount for preventing said control mechanism form being set into said second condition.
Claim 9
Dependent Claim
36 words
The combination according to claim 7 comprising means controlled by said last-mentioned means when said member is out of said home position for preventing movement of said control mechanism between said first and said second conditions.
Claim 10
Dependent Claim
100 words
In a checkwriter having an accumulator; printing mechanism; means including sectors differentially movable from home positions for setting up amounts to be printed; and cyclically operable drive means; the combination comprising: control mechanism settable in an add condition for causing said sectors to add amounts into said accumulator during movement of said sectors away from said home positions, said control mechanism being settable in a subtract condition for causing said drive means to drive said sectors to said home positions and for causing said sectors to subtract amounts from said accumulator during movement of said sectors to said home positions.
Claim 11
Dependent Claim
100 words
In a checkwriter having an accumulator; printing mechanism; means including sectors differentially movable from home positions for setting up amounts to be printed; and cyclically operable drive means; the combination comprising: control mechanism settable in an add condition for causing said sectors to add amounts into said accumulator during movement of said sectors away from said home positions, said control mechanism being settable in a subtract condition for causing said drive means to drive said sectors to said home positions and for causing said sectors to subtract amounts from said accumulator during movement of said sectors to said home positions.
Claim 12
Dependent Claim
57 words
The combination according to claim 9 comprising means for sensing an overdraft condition in said accumulator; means controlled by said sensing means upon sensing an overdraft condition for preventing movement of said sectors out of said home positions; and means controlled by said control mechanism when set in said add condition for rendering said sensing means inoperative.
Claim 13
Dependent Claim
68 words
The combination according to claim 10 comprising spring means for rendering said sensing means inoperative; means including a latch operable by said drive means for normally rendering said sensing means inoperative during the major portion of a cycle and for rendering said sensing means operative during the remainder of said cycle; and means controlled by said control mechanism when set in said add condition for releasing said latch.
Claim 14
Dependent Claim
23 words
The combination according to claim 9 comprising means controlled by said drive means for invariably setting said control mechanism in said subtract condition.
