Holding trays for electronic components have different dimensions, depending upon the manufacturer, and are, thus, non-standardized. The invention is a device for holding trays of this kind, which has a tray-shaped carrying element. The carrying element includes a holding region for at least one holding tray, which has variable dimensions for adapting to the dimensions of the at least one holding tray. The carrying element also has a rectangular-shaped edge region with outer surfaces. Guide elements are provided on the outer surfaces of the rectangular edge region. In one embodiment according to the invention, the guide elements are grooves with toothed rack profiles on an end of the grooves. Guide devices such as a pinion, groove block or roller engage in the toothed rack profiles to guide and transport the device. In another embodiment according to the invention, the holding region includes locking pins (71, 7b) disposed in a contact surface of the holding region, which displace to the dimensions of the at least one holding tray.
