Abstract
An image reading apparatus in which a session timeout does not take place in a case where user's confirmation is obtained before image data obtained by reading originals is transmitted. Before transmission of image data, a control unit determines whether a protocol having a time out is selected. If the selected protocol has a timeout, the control unit determines whether a memory is in a memory full state each time image data of one page is stored into the memory. If the memory is in a memory full state, the user is requested to confirm as to whether transmission is to be performed. If the necessity of transmission is confirmed by the user, the control unit establishes a session with a destination and transmits image data of pages stored in the memory to the destination.
Claims10
An image reading apparatus comprising:
- a reading unit configured to read originals for a job including more than one original;
- an interface unit configured to transmit data in accordance with a first protocol and a second protocol;
- and
- a transmission control unit configured to control transmission using each of a first type of transmission method and a second type of transmission method, based on protocol information indicating one of the first protocol and the second protocol for transmitting data of the original for the job,
- wherein, in the first type of transmission method, data of one original is transmitted by said interface unit in accordance with the first protocol each time the one original is read by said reading unit,
- wherein, in the second type of transmission method, data of the originals is transmitted by said interface unit in accordance with the second protocol in response to all of the originals being read by said reading unit,
- wherein the first protocol and the second protocol are different protocols.
A control method for an image reading apparatus, the image reading apparatus including an interface unit configured to transmit data in accordance with a first protocol and a second protocol, the control method comprising:
- a reading step of reading originals for a job including more than one original;
- and
- a transmission control step of controlling transmission using each of a first type of transmission method and a second type of transmission method, based on protocol information indicating one of the first protocol and the second protocol for transmitting data of the original for the job,
- wherein, in the first type of transmission method, data of one original is transmitted by said interface unit in accordance with the first protocol each time the one original is read by said reading step,
- wherein, in the second type of transmission method, data of the originals is transmitted by said interface unit in accordance with the second protocol in response to all of the originals being read by said reading step,
- wherein the first protocol and the second protocol are different protocols.
An image reading apparatus comprising:
- a reading unit configured to read originals for a job including more than one original;
- a USB interface configured to transmit data in accordance with a USB protocol;
- a network interface configured to transmit data in accordance with a network protocol;
- and
- a transmission control unit configured to control transmission using each of a first type of transmission method and a second type of transmission method, based on protocol information indicating one of the USB protocol and the network protocol for transmitting data of the originals,
- wherein, in the first type of transmission method, data of one original is transmitted by said USB interface each time the one original is read by said reading unit,
- wherein, in the second type of transmission method, data of the originals is transmitted by said network interface in response to all of the originals being read by said reading unit.
A control method for an image reading apparatus, the image reading apparatus including a USB interface configured to transmit data in accordance with a USB protocol and a network interface configured to transmit data in accordance with a network protocol, the control method comprising:
- a reading step of reading originals for a job including more than one original;
- a transmission control step of controlling transmission using each of a first type of transmission method and a second type of transmission method, based on protocol information indicating one of the USB protocol and the network protocol for transmitting data of the originals,
- wherein, in the first type of transmission method, data of one original is transmitted by said USB interface each time the one original is read by said reading step, wherein, in the second type of transmission method, data of the originals is transmitted by said network interface in response to all of the originals being read by said reading unit.
