Has been.

In the DSVC, connection with a printer for printing out a recorded photographed image is an important problem.

[0004] For example, if an analog signal line such as a video tape recorder is connected to a printer, the connection is simple and easy, but the signal is apt to deteriorate and the image quality is deteriorated.

Further, if the digital signal line is used for connection, the signal is not deteriorated, but a plurality of connections are required, resulting in an increase in size of the device.

Therefore, the IC card mounting portion is provided in the printer so that signals can be exchanged between the DSVC and the printer.
It is considered to be performed via a C card.

Further, since the number of images that can be taken with one IC card is limited, the user needs to go to the printer main body in order to replace the card, and the operation is restricted, which is not convenient. There was a problem.

An object of the present invention is to provide an image printing apparatus having good operability.

[0010]

In order to achieve the above object, the present invention relates to a mounting section for mounting an image data recording medium, a data reading section for reading image data from the image data recording medium, and an apparatus main body. A remote controller including a transmission unit that transmits an operation signal and image data, a reception unit that receives the transmission signal of the remote controller, a printer unit that performs print processing based on the received image data, and the image data. And a display unit for displaying an image based on the above.

Further, it is characterized in that the remote controller wirelessly transmits to the apparatus main body.

The remote controller and the apparatus main body can be bidirectionally communicated with each other, and the image data captured by the printer unit can be transmitted to the remote controller and recorded on an image data recording medium.

Further, the image data subjected to the data compression processing is transmitted.

[0014]

According to the above means, by mounting the image data recording medium on the remote controller, the image data recorded on the image data recording medium can be wirelessly transmitted from a position distant from the apparatus main body. Images are displayed and printed out based on the image data transmitted from the main body.

By enabling bidirectional communication between the remote controller and the apparatus main body, the image data captured by the printer unit can be recorded on the image data recording medium mounted on the remote controller, and the apparatus main body serves as an image input device. Can be used.

Further, by using the compressed data for the image data to be transmitted, the data transmission time can be shortened.
