A sheet holder (100) for holding sheets (50) comprising a housing (101) defining first and second side walls (120 and 110) spaced apart from each other and defining a slot (170) therebetween. The first and second side walls (120 and 110) also define a bottom aperture (172) leading into the slot (170). A plurality of guiding grooves (134) are defined in the first side wall (120) facing the slot (170). The guiding grooves (134) define substantially opposed groove top and bottom ends (136 and 138) and extend further away from the second side wall (110) adjacent the groove top end (136) than adjacent the groove bottom end (138). Holding elements are each at least partially received in a respective one of the guiding grooves (134) and movable therealong. At least part of the holding elements (134) remains in the guiding grooves (134) at all positions therealong. |
