First Claim
1. An electronic equipment comprising:
- a first computer;
a first power line over which power is supplied to said first computer;
a second computer;
a second power line over which power is supplied to said second computer; and
a switch having one terminal thereof connected with a data bus to which said first computer is connected, and having the other terminal thereof connected with a data bus to which said second computer is connected,wherein when power is supplied to said second computer over said second power line, said switch connects the data bus to which said first computer is connected with the data bus to which said second computer is connected, and when no power is supplied to said second computer over said second power line, said switch isolates the data bus to which said first computer is connected from the data bus to which said second computer is connected.

Abstract
An electronic equipment comprises a first computer, a first power line over which power is supplied to the first computer, a second computer, a second power line over which power is supplied to the second computer, and a switch having one terminal thereof connected with a data bus to which the first computer is connected, and having the other terminal thereof connected with a data bus to which the second computer is connected. When power is supplied to the second computer over the second power line, the switch connects the data bus to which the first computer is connected with the data bus to which the second computer is connected. When no power is supplied to the second computer over the second power line, the switch isolates the data bus to which the first computer is connected from the data bus to which the second computer is connected.

17. A camera comprising:
-
a first computer; a first photographic operation circuit to be engaged in at least portion of photographic operations, and controlled by said first computer; a second computer; a second photographic operation circuit to be engaged in a different portion of the photographic operations from those of said first photographic operation circuit, and controlled by said second computer; a power circuit including a first power line over which power is supplied to said first computer and a second power line over which power is supplied to said second computer; and a switch having one terminal thereof connected with a data bus to which said first computer is connected and having the other terminal thereof connected with a data bus to which said second computer is connected, wherein when power is supplied to said second computer over said second power line, said switch connects the data bus to which said first computer is connected with the data bus to which said second computer is connected, and when no power is supplied to said second computer over said second power line, said switch isolates the data bus to which said first computer is connected from the data bus to which said second computer is connected. - View Dependent Claims (18, 19, 20)
