Abstract
A housing of an electronic cassette has an inclined surface which is formed between a side surface and a rear surface thereof and inclined relative to the side surface and the rear surface. An antenna opening through which a radio wave is transmitted is formed on the inclined surface. Since the antenna opening is formed on the inclined surface, the antenna opening is not blocked by a rear plate of a holder of an upright radiographic stand or a supine radiographic stand, and the antenna opening is not blocked by a side panel of an outer grid. Both in the case where the electronic cassette is set to the holder and in the case where the outer grid is attached to the electronic cassette, it is possible to perform stable wireless communication.
Claims13
An electronic cassette comprising:
- an image detector for detecting a radiation image of a subject based on radiation having been transmitted through the subject;
- a housing for housing the image detector, the housing having a front surface on which the radiation is incident, a rear surface facing the front surface, four side surfaces and an inclined portion, the inclined portion being inclined relative to at least a part of the side surfaces and the rear surface, and having a first end and a second end which is opposite to the first end, the first end contacting to at least one of the side surfaces, a second end contacting to the rear surface;
- an antenna for use in wireless transmission of at least the radiation image via radio waves, the antenna being disposed inside the housing;
- and
- an antenna opening through which the radio waves are transmitted, at least part of the antenna opening being formed on the inclined portion,
- wherein the antenna is disposed at a position which faces the antenna opening, and
- wherein the antenna is disposed to be located at a center of the antenna opening, and so that an installation surface on which the antenna is installed is parallel to the inclined portion.
