 The present invention relates to a white board wiper having a casing engaged with a body on which fabric is wrapped. The spare section of the fabric is stored in the casing so that the fabric does not need to change frequently.
 A conventional white board wiper is shown in FIG. 1 and generally includes a case 11 made of plastic material and a foam body is connected to the case 11 and a fabric 10 wraps on the foam body. The white board marker generally is filled with water-base liquid and is used to write on the white board. The wiper is able to wipe the result on the white board out by the white board markers by adhering the liquid on the fabric. However, the adhered liquid cannot be cleaned from the fabric by petting so that the conventional white board wipers have to be change periodically and this costs much. The other conventional white board wiper is shown in FIG. 2 and includes a case 14 in which hook-loop type members 13 and magnetic members 15 are received. A fabric 12 is adhered on the hook-loop type members 13 and the wiper can be adhered on the white board by the magnetic members 15. Although the wipers improve the drawbacks of the first type of wipers, the fabric 12 still needs to be changed frequently.
 The present invention intends to provide a white board wiper that has spare section stored in the casing and the user can adjust the fabric to use every section of the fabric.
 In accordance with one aspect of the present invention, there is provided a white board wiper and comprising a body with adhered members connected to three sides of the body and a fabric is wrapped around the body and adhered on the adhered members. A casing is removably engaged with the body so that a spare section of the fabric is received in the casing.
 The primary object of the present invention is to provide a white board wiper wherein the fabric does not need to be replaced frequently.
 These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.
FIG. 1 is a side view to show a conventional white board wiper;
FIG. 2 is a perspective view to show another conventional white board wiper;
FIG. 3 is a cross sectional view to show a white board wiper of the present invention, and
FIG. 4 is a perspective view to show the white board wiper of the present invention.
 Referring to FIGS. 3 and 4, the white board wiper of the present invention comprises a body 21 having four sides and three adhered members 25 are connected to three sides of the body 21. a magnetic member 22 IS connected on the fourth side of the body 21. A fabric 20 is wrapped around the body 21 and adhered on the adhered members 25, wherein the magnetic member 22 is covered by the fabric 20. A casing 23 is removably engaged with the body 21 and spare section of the fabric 20 is stored in the casing 23. When the using surface of the fabric 20 is contaminated, the user simply removes the casing 23 and peels the fabric 20 to shift the fabric 20 and engage the casing 23. By this way, the surface of the fabric 20 of the wiper is easily changed within a short period of time. It is to be noted that the fabric 20 can be used on both sides and the fabric 20 is washable.
 There are many ways to connect the casing 23 and the body 21. In this embodiment, the casing 23 has a flange 24 extending from an inner side of the casing 23 and the flange 24 securely clamps the body 21.
 While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope and spirit of the present invention.
