2. Description of the Prior Art A conventional clipboard 14, as shown in Figs. 1 and 2, is composed of a plastic board 11 and a clamp member. 12. The clamp member 12 consists of a base plate 121, a twist spring 122 and a clamping plate 123. The twist spring 122 is positioned between the base plate 121 and the clamping plate 123 so as to enable the clamping plate 123 to produce a clamping force. Besides, the base plate 121 has two through holes 1211 respectively bored at two preset locations matching with two through holes 111 of the plastic board 11 and riveted together by rivets l3.Thus, when the clamping plate 123 of the clamp member 12 is pressed downward, there forms a clamping openin5 between the clamping plate 123 and the plastic board lI for paper to be placed and clamped therein, with the plastic board 11 serving as a bottom pad for facilitating writing or drawing on the paper clamped thereon.
However, the conventional clipboard 12 has the following drawbacks.
1. The plastic board 11 and the clamp member 12 have to be made separately, and the clamp member is composed of the base plate 121, the twist spring 122 and j the clamping plate 123. Besides, the base plate 121 and the plastic board 11 are respectively bored with two through holes 1211, 111 at preset positions matching with each other for the convenience of combining the base plate 121 with the plastic board 11 together by means of rivets 13, thus complicating producing and assembling processes, increasing producing and assembling cost and not advantageous for economic gain.
2. The clamp member 12 of the clipboard 10 is high, so it needs to take a large space to be packed in a carton, increasing packing and transporting cost.
