Claims (1)

[Claims for Utility Model Registration] 1. A reel shaft attached to a chassis includes a reel cap portion of the reel shaft, a tape reel receiving surface for receiving the tape reel of a tape cassette, and a vertically movable portion on the outer periphery of the reel cap portion. A reel stand main body is rotatably inserted and includes a reel blade that is freely biased upwardly by a spring and has at least one stay that protrudes in the radial direction, A through hole that penetrates into the inside of the reel cap is formed in the top wall of the reel cap, and at least one notch recessed in the radial direction is formed over the entire length of the inner peripheral wall of the through hole in the vertical direction. a reel cap portion in which at least one concave portion is formed radially from the lower part of the inner circumferential wall to the lower surface of the top wall; and an insertion shaft body that can be inserted into the through hole, and the peripheral wall of the insertion shaft body. a thrust receiving part having at least one protrusion protruding in the radial direction formed on the lower part thereof and a flange protruding in the shape of a disc on the top of the insertion shaft on the opposite side of the protrusion; The shaft body is inserted into the through hole of the reel cap part, and the protrusion part is inserted into the notch part from above the reel cap part, respectively, and the inserted protrusion part is formed on the lower surface of the top wall. The stay of the reel blade is fitted into the recessed part, the lower end of the insertion shaft body is brought into contact with the upper end of the reel stand shaft, and the stay of the reel blade is biased by the spring. It has a structure that stops when it comes into contact with the flange, and the height of the tape reel receiving surface can be adjusted by changing the vertical depth of the recessed part of the reel cap part or the vertical thickness of the protruding part of the thrust receiving part. A height adjustment mechanism for a tape reel receiving surface of a reel stand, which is characterized by adjusting the height. 2 A plurality of thrust receivers are formed, and
The reel according to Claim 1 of the Utility Model Registration Claim, wherein the thrust receiving parts have different thicknesses in the vertical direction of the protruding parts, and one of the thrust receiving parts is replaceably attached to the reel cap part. Height adjustment mechanism for the tape reel receiving surface of the stand. 3 A plurality of recesses are formed, and each recess has a different depth in the vertical direction, and the protrusion of the thrust receiver is removably fitted into any of these recesses. A height adjustment mechanism for a tape reel receiving surface of a reel stand according to claim 1, which is a registered utility model.
