Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
216 words
An electronic oven comprising a housing provided with a heating chamber and heating time indicating windows, a highfrequency oscillator, second and minute time unit setting shafts provided in the housing to be rotatable about the longitudinal axis thereof and movable in an axial direction, rotatable second and minute indication bodies associated with each other so that a remaining heating time is displayed through the heating time indicating windows, connecting means operatively connecting the time setting shafts to the time indication bodies to cause the time indication bodies to be rotated an amount corresponding to the extent of rotation involved when the time setting shafts are rotated from an original position after an axial movement, and adopted to cut off the operative connection between the time indication bodies and the time setting shafts when the time setting shafts are returned to the original position, a starting shaft provided in the housing to be movable in an axial direction, means adapted to return the time setting shafts to the original position when the time starting shaft is moved, means for causing the high-frequency oscillator to be operated when the starting shaft is moved, and a timer motor causing the time indication bodies to be rotated by said amount in a reverse direction when the starting shaft is moved.

Claim 3
Dependent Claim
26 words
An electronic oven according to claim 1 further including means for holding the time setting shafts in a position where the time setting shafts are moved.
Claim 4
Dependent Claim
38 words
An electronic oven according to claim 1 in which said second and minute time unit setting shafts are coaxially provided relative to each other, the time setting shafts having outwardly extending one end where knobs are provided respectively.
Claim 5
Dependent Claim
99 words
An electronic oven according to claim 1 in which the minute indication body has a 10-minute indication body and a 1-minute indication body which are connected to the second indication body in a manner that when said second indication body makes one rotation the 1-minute indication body makes one-tenth rotation and when said 1-minute indication body makes one rotation the 10-minute indication body makes one-tenth rotation, said second indication body bearing equidistantly spaced numerals within numerals 0-59 on its entire peripheral surface and said 1-minute and 10-minute indication bodies bearing equidistantly spaced numerals 0-9 on their entire peripheral surfaces.
Claim 6
Dependent Claim
50 words
An electronic oven according to claim 1 in which said respective time indication bodies are light transmissive drums, a light source is provided within the outermost one of the time indication bodies, and means is provided so as to make uniform light amounts passed through the heating time indicating windows.
Claim 7
Dependent Claim
27 words
An electronic oven according to claim 1 further including sound producing means for informing the completion of heating when all the time indication bodies stop their rotation.
