DETAILED DESCRIPTION OF THE INVENTION Referring to figures 1 to 4, 7 and 9, the toy drawing desk 10 according to a preferred embodiment of the present invention is shown in exploded and perspective views. The toy drawing desk 10 comprises two rollers 15 (only 10 one is seen in figure 7) adapted to support an elongated paper sheet 21. Two handles 18 are coupled to respective front ends of the rollers 15, to rotate them. The handles 18 are removably secured to the rollers 15. The handles 18 are accessible from the exterior of the desk to allow a user to rotate the rollers and change the images to be coloured. 15 The desk 10 further comprises a case having a substantially flat surface 14 and a window 13 delimiting a viewing area over the flat surface 14. Each of the compartments embodies a space 17 adapted to receive a roll 15 of paper sheet as shown in figure 7. In the illustrated embodiment, there are two compartments 16 located 20 respectively on both sides of the viewing area. The compartments 16 are placed substantially parallel to each other and have securing means for securing the rollers 15 in operating position. Each roller 15 is rotatably mounted in its space 17. A sheet of paper 21 on which is printed images to be coloured, is wound up on the rollers 15. The rollers 15 are operatively 25 connected to two handles 18.

WO 01/05605 PCT/CAOO/00839 5 In use, the handles 18 are rotated to a given direction to allow the paper to unroll from one of the roller and to roll up to the other roller. The rollers 15 are secured in their space 17 in such a way that the paper sheet does not ripple nor undulate upon scrolling the paper sheet. The rollers 15 when 5 placed in the compartments 16 are substantially parallel to each other and rotatably mounted in their space 17. Friction means are also provided for exerting a predetermined frictional force against the rotation of the rollers. These friction means allow scrolling of the image all the while preventing loose movement of the paper sheet. 10 The case is shaped as a flat rectangular parallelepiped with four corners and is preferably made of moulded plastic material. The window 50 allows user to have access to the paper sheet to be coloured. As best seen in figure 4, each compartment 16 comprises inner 17 and outer 19 elongated spaces extending between front and rear portions of the 15 case. The inner 17 and outer 19 spaces of each compartment are separated by a wall. The inner space 17 is designed to receive a corresponding roller 15 and the outer space 19 is designed to be a storage space for small objects such as pencils and crayons. Preferably, pivoting lids 20 for covering the compartment 16 are provided. 20 The lids 20 have a general rectangular form and has a first side edge 24 that is pivotally fixed on the exterior limits of the case and a second side edge 26 that fits on the case, by a simple engaging mechanism. The lids may be mounted on the case by means of hinges 11. In the illustrated embodiment, two pairs of hinges 11 are provided and are located at the 25 four corners of the case. Each hinge 11 embodies a complementary facing part of the case and the lid. Each hinge 11 further comprises a connector for connecting the complementary facing parts. A plurality of stoppers 28 may also be provided on the surface of the lids 20.

The knob 34 is located on a front portion of the case. The handles 18 are held in place by a friction 5 means on the lower end of each compartment. The friction means may be resilient arms 30 which preferably press the central portion of the shaft 32 in order to hold the handle in place. Each shaft 32 further comprises an elongated discontinuous protuberance 33 extending around the circumference thereof at a given distance of the corresponding knob 34. 10 Each of the lids has a curved edge that fits around the corresponding shaft 32, when in closed position, between the corresponding protuberance 33 and knob 34 to secure the corresponding handle 18 in operation position. This prevents any radial movement of the handle to the outside of the desk, when the lid 20 is closed. The end of the shaft 32 is preferably provided 15 with a plurality of crests 38 for securing the roller 15 from the inside. As mentioned herein above, in the present embodiment, the friction means may be a pair of resilient arms 30 adapted to apply pressure on the corresponding shaft along radial direction thereof to at the same time prevent loose movement of the paper sheet and allow unwinding thereof by 20 the user. Referring now to figure 6, the top end of each compartment sides comprises securing means 40 for holding the roller in position during rotation. The securing means 40 comprises a stopper 41 connectable with the rear end of the corresponding roller and a pair of U-shaped supports 42 25 for supporting respectively rear and front portions of the corresponding roller.
