Abstract

Abstract (1.) An electronic checkbook consisting of: (A.) a dedicated microprocessor which continues to perform a specific function and store the information on a day to day basis, even when not otherwise in use, (B.) Checks. (C.) Checking stubs with numbers corresponding to the checks upon which can be kept handwritten records of the balance, checks written, and deposits made. (D.) Checking account deposit slips. (E.) A folder containing all of the above . In regards to the dedicated microprocessor, four high priority routines are present which are able to interrupt the main program: (1.) When the "STOP" position is selected, it halts the processor and turns off the display. (2.) Depressing the "CLEAR" button will clear the display and second register if not in "STOP". (3.) When the "REMOVE PROTECT" button is depressed, the contents of the memory effectively become zero, if not in "STOP". (4.) When the "POST BALANCE" button is depressed, the contents of the display are added to the contents of memory, if not in "STOP". When the unit is set at "START" the contents of the memory will appear in the display.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 98 words
An electronic checkbook comprising: (a) a carrier member having first and second surface portions; (b) a plurality of checks connected to one of said surface portions; (c) a plurality of record members connected to one of said surface portions, said record members each having indicia and guidelines for recording of hand written information thereon; (d) a microprocessor attached to one of said surface portions for computing and maintaining numerical information quantities related to the information contained in said record members; and (e) said record members and said microprocessor being located on said carrier member in directly adjacent relation.
Claim 2
Dependent Claim 98 words
An electronic checkbook comprising: (a) a carrier member having first and second surface portions; (b) a plurality of checks connected to one of said surface portions; (c) a plurality of record members connected to one of said surface portions, said record members each having indicia and guidelines for recording of hand written information thereon; (d) a microprocessor attached to one of said surface portions for computing and maintaining numerical information quantities related to the information contained in said record members; and (e) said record members and said microprocessor being located on said carrier member in directly adjacent relation.
Claim 3
Dependent Claim 43 words
Apparatus according to claim 1, wherein said carrier member is a sheet provided with a fold along a midline to provide a folder wherein said first and second surface portions are on the same side of said sheet and separated by said fold.
Claim 4
Dependent Claim 72 words
Apparatus according to claim 1, wherein said microprocessor includes means for storing information even when said microprocessor is not otherwise in use, means for recalling stored information, and means for displaying stored information upon start whereby displayed information can be affected by the performance of any computational operation or sequence of computational operations and again displayed for error avoidance of approval whereupon the amount may then be stored in the same manner.
Claim 5
Dependent Claim 23 words
Apparatus according to claim 1, wherein said record members are individually removably connected to one of said surface portions of said carrier member.
Claim 6
Dependent Claim 35 words
Apparatus according to claim 1, wherein said checks are located on one of said surface portions of said carrier member and said microprocessor and record members are located on the other of said surface portions.
