Abstract

Abstract In an I/O card that can be inserted into a slot of an electronic device and supplied with electricity therefrom, a first connector can engage a connector provided in the slot of the electronic device. A second connector can engage an external connector of an interconnection cable used to connect the I/O card to an external device. A circuit notifies the electronic device that the I/O card has been loaded to the slot thereof when the external connector is connected to the second connector of the I/o card inserted into the slot. The I/O card receives a supply of electricity from the electronic device, the supply being started after the electronic device is notified by the circuit.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 113 words
An I/O card insertable into an electronic device and supplied with electricity therefrom, said I/O card comprising: a first connector for engaging a corresponding connector provided in the electronic device; a second connector for engaging an external connector of an interconnection cable so as to connect the I/O card to an external device; and a circuit which notifies the electronic device that the I/O card has been inserted therein when the external connector is connected to the second connector of the I/O card inserted into the electronic device, the I/O card receiving a supply of electricity from the electronic device, said supply being started after the electronic device is notified by said circuit.
Claim 2
Dependent Claim 113 words
An I/O card insertable into an electronic device and supplied with electricity therefrom, said I/O card comprising: a first connector for engaging a corresponding connector provided in the electronic device; a second connector for engaging an external connector of an interconnection cable so as to connect the I/O card to an external device; and a circuit which notifies the electronic device that the I/O card has been inserted therein when the external connector is connected to the second connector of the I/O card inserted into the electronic device, the I/O card receiving a supply of electricity from the electronic device, said supply being started after the electronic device is notified by said circuit.
Claim 3
Dependent Claim 60 words
The I/O card as claimed in claim 1, wherein: said second connector of the I/O card comprises a terminal for connecting to the electronic device via said first connector and for connecting to a signal line which detects the I/O card loaded into the electric device; and wherein said terminal is set to a given potential via said external connector.
Claim 4
Dependent Claim 24 words
The I/O card as claimed in claim 2, further comprising a communicating part providing data transfer between the electronic device and the external device.
Claim 5
Dependent Claim 66 words
The I/O card as claimed in claim 1, wherein: said second connector of the I/O card comprises a first terminal for connecting to the electronic device via said first connector and for connecting to a signal line which detects the I/O card loaded into the electronic device, and a ground terminal; and said first terminal and said ground terminal are connected together via said external connector.
Claim 6
Dependent Claim 24 words
The I/O card as claimed in claim 4, further comprising a communicating part providing data transfer between the electronic device and the external device.
Claim 7
Dependent Claim 24 words
The I/O card as claimed in claim 1, further comprising a communicating part providing data transfer between the electronic device and the external device.
Claim 8
Dependent Claim 102 words
An interconnection cable connectable to an I/O card insertable into an electronic device and supplied with electricity therefrom, said interconnection cable comprising: an external connector connectable to a connector of the I/O card; and a circuit part transmitting a detection signal from the I/O card to the electronic device, said detection signal indicating that the I/O card has been inserted into the electronic device when said external connector is connected to said connector of the I/O card inserted, the I/O card receiving a supply of electricity from the electronic device, said supply being started after the electronic device receives said detection signal.
Claim 9
Dependent Claim 102 words
An interconnection cable connectable to an I/O card insertable into an electronic device and supplied with electricity therefrom, said interconnection cable comprising: an external connector connectable to a connector of the I/O card; and a circuit part transmitting a detection signal from the I/O card to the electronic device, said detection signal indicating that the I/O card has been inserted into the electronic device when said external connector is connected to said connector of the I/O card inserted, the I/O card receiving a supply of electricity from the electronic device, said supply being started after the electronic device receives said detection signal.
Claim 10
Dependent Claim 77 words
A power saving method for an I/O card insertable into an electronic device and supplied with electricity therefrom, said power saving method comprising the steps of: outputting a detection signal notifying the electronic device that the I/O card has been inserted therein when an external connector is connected to a connector of the I/O card; and providing a supply of electricity from the electronic device to the I/O card in response to receipt of said detection signal.
Claim 11
Dependent Claim 77 words
A power saving method for an I/O card insertable into an electronic device and supplied with electricity therefrom, said power saving method comprising the steps of: outputting a detection signal notifying the electronic device that the I/O card has been inserted therein when an external connector is connected to a connector of the I/O card; and providing a supply of electricity from the electronic device to the I/O card in response to receipt of said detection signal.
