摘要： A VCR has a reel sensor prism device fabricated by being separated into a scattering member and a fixing member. The scattering member includes a cylindrical body part for transmitting light and a head formed to the upper portion of the body part for scattering the light. A fixing member is formed with a center hole of being inserted with the body part of the scattering member, and two pairs of hooks are formed to the lower end. A base for supporting and fixing the fixing member is formed with two pairs of hook holes and a thruhole for passing the light generated from a reel sensor light emitting part therethrough. By this construction, the light generated from the reel sensor light emitting part is prevented from being scattered at the body part to minimize loss of the transmitted light, thereby maximizing the transmitting effect of the light and preventing a malfunction of the VCR. Also, the assembling is completed by fitting the hooks of the fixing member into the hook holes to improve assemblage and productivity.
