PURPOSE:To lock precisely guide rolls to unload a tape from a small-sized tape cassette charged in a case body having the same size as a standard size tape cassette, by locking the guide roll by a locking member pivotally mounted on the body. CONSTITUTION:A tape is unloaded from the small-sized tape cassette charged in a case body (not shown in figure) having the same size as the standard size tape cassette by unloading arm means. A pair of unloading arm means are arranged on each side of the take-up reel and supply reel sides. A lever pushes the locking member 32 pivotally mounted on the base plate 6 of the case body through a cam plate 41, a plate spring 40 and a slide arm 39 and holds the shaft of a guide roll 12 pivotally mounted on the leading end of the unloading arm (not shown in figure) together with a locking part 35. The same structure is prepared on the take-up reel side. Consequently, the guide rolls are supported rigidly and the tape can be travelled stably. |
