(Not shown) are supported in a vertical arrangement, but a reinforcing angle 16 for supplementing rigidity can be arranged at the upper end and the lower part, while the sheet feeding device is arranged to overlap at an intermediate portion. Therefore, in view of a state in which a means for supplementing the rigidity of the panels 13 and 14 is not practically available, the above-mentioned feeding guide 2-2 and the auxiliary feeding guide 2-3 are used as alternative means. .
[0018]
Further, as shown in FIGS. 2 (a) and 2 (b), in order to secure the fixing means of the feed guide 2-2 and the auxiliary feed guide 2-3, the feed guide 2-2 and the auxiliary feed guide 2-3 are respectively provided at both ends or intermediate portions. Preferably, grooves or holes 2-21, 2-22, 2-31, 2-32 for screw fixing are formed on the back side of the guide surface of the sheet.
[0019]
