0 is the same as the glass piece sorting apparatus 1 of the first embodiment in the alignment, transportation, sorting instruction and removal of the crushed glass piece 9, and only the display of the crushed glass piece 9 instructed to be sorted is different. The detailed description is omitted, and the display (illumination) will be described. In FIG. 5, when the broken glass pieces 9 conveyed in one row reach the sorting instruction position SP, the worker 29 can use the broken glass suitable for reuse. When it is determined that the piece is the piece 9 and the push button switch 26 is operated to transmit a sorting instruction signal to the glass piece sorting device 80, the signal is transmitted to the control device 28 and the lighting device 81 is turned on.

Thus, the illuminating device 81 illuminates the white glass 9A from below the net conveyor 82, for example, which can transmit light in the vertical direction, and distinguishes the crushed glass pieces from the other crushed glass pieces 9 and instructs the operator 29 to sort the crushed glass pieces. 9 is clearly recognized.

In the above embodiment, the lighting device 81 is described as being turned on when the push button switch 26 is operated. However, the lighting device 81 is always turned on and the broken glass pieces 9 conveyed from below the net conveyor 82. Illumination may be used to facilitate identification of the worker 29, and when the push button switch 26 is operated, the illuminance may be increased to indicate that a sorting instruction has been given.
