2. Description of the Related Art Conventionally, there has been proposed a still image transmission system for transmitting still image data between still image transmission devices. The still image transmission device includes a portable type and a stationary type. A file device such as a magneto-optical disk device is connected to the stationary still image transmission device. For example, still image data is transmitted from a portable still image transmission device to a stationary still image transmission device via a telephone line.

[0003]

However, the conventional portable still image transmission device cannot communicate with the stationary still image transmission device, and, for example, a still image file recorded on a magneto-optical disk cannot be transferred over the telephone line. It was also impossible to receive over.

On the other hand, it was possible to receive a desired still image file between the stationary still image transmitting devices by typing in the file name with the attached keyboard, but all the still image files are successively transmitted. And it was impossible to receive.

In view of this, the present invention provides a still image transmission system which allows one still image transmission device to successively and continuously receive still image files stored in the file device of the other still image transmission device. Is.

[0006]

The present invention provides a still image transmission system configured to transmit still image data between a first still image transmission device and a second still image transmission device. Of the still image transmission device is equipped with a file device for storing a plurality of still image files each having a file name, and the first still image transmission device requests all the still image files corresponding to the acquired file names. Mode setting means for setting the all still image file request mode, and all still image files corresponding to the file name obtained from the file device via the second still image transmission device when the all still image file request mode is set. And a control means for sequentially reading out.

[0007]

When the first still image transmission device is set to the all still image file request mode, the first still image transmission device sends the second still image transmission request for the still image file corresponding to the acquired file name. Sequentially send to device. Therefore, still image files corresponding to the file names obtained from the second still image transmission device are sequentially transmitted to the first still image transmission device.
