PURPOSE:To hold an object with fingers firmly by providing a cabinet with a plurality of guide shafts parallel with racks and arranging the fingers provided projectingly on the racks closely to the respective shafts. CONSTITUTION:Guide shafts 28a and 28b are fixed to a cabinet body 22 in parallel with racks 26a and 26b, and the brackets 32a and 32b fixed to each of the side ends of the racks 26a and 26b are inserted respectively by the guide shafts 28a and 28b slidably. The brackets 32a and 32b are provided with fingers 30a and 30b respectively. Therefore, the fingers are neither shifted nor tilted toward each other. The fingers 30a and 30b are provided with a pair of link arms with one end of the respective link arms fitted rotatably and another end engaged forming a jig 38. This jig 38 is swung vertically downward according to the movements of the fingers approaching and separating to and from each other. Such arrangement of the jig as to be abutted on the upper face of the object held with the fingers prevents it from tilting.
