A conveying device according to the present invention includes a first connection mechanism provided on an upper surface, a base member provided on the upper surface, a sliding mechanism that relatively and slidably moves the position of the first connection mechanism relative to the base member on the slide axis, and a traveling mechanism that makes the conveying device travel. The first connection mechanism has an over-riding portion provided on the slide axis, and a connection part connected with the object to be conveyed. The over-riding portion is in an over-riding state of over-riding an upper surface of the base member when the sliding mechanism slidably moves the position of the first connection mechanism relative to the base member. The connection part performs a lifting operation to be connected with the object to be conveyed when the over-riding portion is in the over-riding state.

Conveying device

A conveying device according to the present invention includes a first connection mechanism provided on an upper surface, a base member provided on the upper surface, a sliding mechanism that relatively and slidably moves a position of the first connection mechanism on a slide axis relative to the base member, and a traveling mechanism that makes the conveying device travel. The first connection mechanism is connected with a carriage at a predetermined connection position. The sliding mechanism slidably moves the first connection mechanism between the connection position and a predetermined conveyance position spaced away from the connection position on the slide axis in a state in which the first connection mechanism is connected with the carriage. The traveling mechanism makes the conveying device travel in a state in which the first connection mechanism is positioned in the conveyance position.

An object of the present invention is to obtain a display device having excellent display quality by appropriately modifying the chromaticity of images. In this display device, a correction processing part (CPU) determines a first chromaticity change amount stored in memory () on the basis of a first cumulative usage amount, which is the cumulative usage amount of an LED () up to a present time, the cumulative value having been measured by a counter (), and the correction processing part also determines a second chromaticity change amount stored in the memory () on the basis of a second cumulative usage amount, which is the cumulative usage amount of the LED () up to a time when the chromaticity of a pixel is adjusted by a chromaticity adjusting part (CPU), the cumulative value having been measured by the counter (). Then, by subtracting the second chromaticity change amount from the first chromaticity change amount, the correction processing part obtains the value to which the chromaticity is to be modified, and modifies an image signal on the basis of the value to which the chromaticity is to be modified.
