Abstract
Abstract An electronic cash register electrically communicates with an electronic weighing scale. An interface circuit is included in the electronic cash register for introducing weight information data from the electronic weighing scale into the electronic cash register. An abnormal condition detection system is included in the electronic cash register for detecting an abnormal condition occurring within the electronic weighing scale. The electronic cash register includes a synthetic speech sound generation system for audibly informing an operator of the abnormal condition detected by the abnormal condition detection system.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
108 words
A combined electronic cash register and weighing scale comprising: an electronic cash register; an electronic weighing scale for developing weight information data for the electronic cash register, said electronic cash register including, an interface circuit for receiving said weight information data from said electronic weighing scale and developing an output signal in response thereto; detection system means responsive to the output signal from said interface circuit for detecting an abnormal condition occurring within said electronic weighing scale and developing a detection output in response thereto; and an announce system responsive to said detection output for audibly announcing the abnormal condition of said electronic weighing scale in response thereto.
Claim 2
Dependent Claim
108 words
A combined electronic cash register and weighing scale comprising: an electronic cash register; an electronic weighing scale for developing weight information data for the electronic cash register, said electronic cash register including, an interface circuit for receiving said weight information data from said electronic weighing scale and developing an output signal in response thereto; detection system means responsive to the output signal from said interface circuit for detecting an abnormal condition occurring within said electronic weighing scale and developing a detection output in response thereto; and an announce system responsive to said detection output for audibly announcing the abnormal condition of said electronic weighing scale in response thereto.
Claim 3
Dependent Claim
57 words
The combined electronic cash register and weighing scale of claim 1, wherein said detection system means comprises: a first detection system means for detecting whether said electronic weighing scale is electrically connected to said electronic cash register, and developing a first detection output when said electronic weighing scale is not accurately connected to said electronic cash register.
Claim 4
Dependent Claim
29 words
The combined electronic cash register and weighing scale of claim 2, wherein said announce system audibly announces synthetic speech sound of "SCALE" in response to said first detection output.
Claim 5
Dependent Claim
41 words
The combined electronic cash register and weighing scale of claim 3 further comprising: display means responsive to said first detection output for providing a display indication indicative of the inaccurate connection of said electronic weighing scale to said electronic cash register.
Claim 6
Dependent Claim
50 words
The combined electronic cash register and weighing scale of claim 1, wherein said detection system means comprises a second detection system means for detecting whether a weighing platform of said electronic weighing scale is stable or is fluctuating, and developing a second detection output when said weighing platform is fluctuating.
Claim 7
Dependent Claim
30 words
The combined electronic cash register and weighing scale of claim 5, wherein said announce system audibly announces a synthetic speech sound of "MOTION" in response to said second detection output.
Claim 8
Dependent Claim
32 words
The combined electronic cash register and weighing scale of claim 6 further comprising display means responsive to said second detection output for providing a display indication indicative of the fluxuating weighing platform.
Claim 9
Dependent Claim
48 words
The combined electronic cash register and weighing scale of claim 1, wherein said detection system means comprises: a third detection system means for detecting whether a zero adjustment is achieved in said electronic weighing scale, and developing a third detection output when the zero adjustment is not achieved.
Claim 10
Dependent Claim
31 words
The combined electronic cash register and weighing scale of claim 8, wherein said announce system audibly announces a synthetic speech sound of "ZERO CENTER" in response to said third detection output.
Claim 11
Dependent Claim
38 words
The combined electronic cash register and weighing scale of claim 9 further comprising display means responsive to said third detection output for providing a display indication indicative of the fact that the zero adjustment has not been achieved.
Claim 12
Dependent Claim
65 words
The combined electronic cash register and weighing scale of claim 1, wherein said detection system means comprises: a fourth detection system means for detecting whether an article to be measured by said electronic weighing scale is within a weighing range of said electronic weighing scale, and developing a fourth detection output when said article is not within the weighing range of said electronic weighing scale.
Claim 13
Dependent Claim
32 words
The combined electronic cash register and weighing scale of claim 11, wherein said announce system audibly provides a synthetic speech sound of "OUT OF RANGE" in response to said fourth detection output.
Claim 14
Dependent Claim
44 words
The combined electronic cash register and weighing scale of claim 12 further comprising display means responsive to said fourth detection output for providing a display indication indicative of the fact that said article is not within the weighing range of said electronic weighing scale.
