Abstract

Abstract The improved portable check recordal device of the present invention includes a cover within which are disposed a block of checks, a check recordal pad and a check calculator, held in the cover by tabs or the like in one or more cover pockets. At least the calculator can be moved by its retaining means to a position outside the cover while still being secured to the cover. Such retaining means may also bear, for example, a memo pad, container, mirror or the like. In one embodiment, both the pad and the block can be slid sideways to parallel each other and overlap the sides of the cover but not each other, and the pad or block carries the calculator with it, for convenience of use. The calculator may be electronic and include recessed keys and plus and minus signs visually displayed in a readout window. One embodiment will purposely exclude all functions, except addition and subtraction for simplicity of operation. The calculator may further have a permanent decimal point and a double zero key, and it may retain the last figures (balance) readout before inactivation, to avoid having to re-enter them upon reactivating the calculator. Since the keys on the calculator would probably be closely spaced, it would be advisable to employ a stylus or a small diameter pen having a reduced opposed end for easy selective depression of a desired key. The device is simple, compact, efficient, easy to use and durable.
