In addition, also can adopt a draft helical spring to replace being turned round volute spring 100, but because under the situation of present embodiment, the actuating range of object of bestowing load is big, and only bestow load to stopping part, therefore, space from structure and spring, above-mentioned way is unfavorable, because turned round volute spring and can be disposed by save space, even and will increase the angle of bestowing load point, also as long as change the wrist 102a of parts, the position of 102b, therefore its wide accommodation is preferred.
Even bestow mechanism as load, for example also can bestow the load that constitutes by friction force for fan-shaped gear 112 or with the casing 32 of fan-shaped gear 112 one rotation at rotation stop position A, B, but shown in present embodiment, because therefore the load variations when using spring members to reduce to stop is preferred.
In addition, employed medium is not limited to the such former tabular medium of medium M of described embodiment, also can use the polygon-shaped or oval-shaped medium of rectangle etc., in addition, unqualified to its recording mode, can be any ways such as optical recording mode, magneto-optical recording.
In addition, in said embodiment, be example, be that example is illustrated to transmit gear 111 with fan-shaped gear 112 as follower gear as the driven wheel that drives this fan-shaped gear 112, but be not limited to the shape of gear or the kind of gear, also can be horizontal gear, crowngear, owing to being in order to solve the deviation of the stop position that causes by the small loosening gap that produces of gear, therefore, irrelevant with the shape or the kind of gear, can be suitable for.
In addition, as the media processing apparatus of load medium conveying mechanism, carrying out the machine that composes and prints that data write with label printing and be illustrated for having used, but be not limited thereto, also can be only to have label machine or only carry out the treating apparatus that data write.
In addition, in the present embodiment, used vertical guide axle 35, but its important part and do not lie in vertically, but expression can guide the mechanical arm meaning of the axle of lifting along the vertical direction, equally, in the present embodiment, conveying arm 36 horizontally rotates, and has used level, but and do not mean that to be exactly level, but represent and can guide the meaning of the leading axle orthogonal directions that mechanical arm moves along the vertical direction.
