To solve problems in a conventional cap opening apparatus wherein it is uneconomical and requires a large storage space to prepare dedicated cap opening apparatus to open the caps of various cans and bottles sealed by different systems and, in a conventional cap opening apparatus having cap opening functions for different applications at both ends of a single output shaft, when one of the functions is set to develop a proper capacity, the other develops an excessive or a sufficient capacity. This cap opening apparatus comprises a speed changing portion 50 having a gear train for matching the output of a motor to the purposes of a plurality of output shafts and an output power changing section for the gear train. Since the speed changing portion transmits optimum torques to the output shafts 133 and 140 and can selectively drive only one output shaft through the output power changing section, safety can be increased. Further, an installation space and a storage space can be saved by adopting a ceiling-hanged type apparatus.

The invention claimed is: 1. A cap opening apparatus comprising: a single power source for generating power; a first last end output power shaft which is capable of rotating by receiving a transfer of the power; a second last end output power shaft which is capable of rotating by receiving a transfer of the power; a first transfer section for transferring the power generated by the single power source to the first last end output power shaft; a second transfer section for transferring, independently from the first transfer section, the power generated by the single power source to the second last end output power shaft at a gear ratio different from that of the first transfer section; a first cap opening section which squeezes a cap of a first article to be opened and opens the cap by rotating the cap by a use of rotation driven by the first last end output power shaft, the first article to be opened being closed by a cap which is fitted to the first article with a screw path; and a second cap opening section which cuts a wall of a second article to be opened and opens the cap by the use of rotation driven by the second last end output power shaft. 2. The cap opening apparatus as claimed in claim 1, wherein the first transfer section has a gear ratio larger than that of the second transfer section. 3. The cap opening apparatus as claimed in claim 1, wherein the first opening section further comprises a cap handling portion for narrowing a gap between squeezing nails for squeezing the cap of the first article to be opened by the rotation in one direction of the first last end output power shaft, and a spring which stores a repulsion for rotation in the other direction at a time of the rotation in one direction; the first last end output power shaft being rotated in the other direction by the repulsion of the spring to release handling of the cap of the first article to be opened by the cap handling portion, when a transfer of power from the single power source to the first last end output power shaft has been finished. 4. The cap opening apparatus as claimed in claim 1, wherein the first opening section further comprises: a lower handling portion which handles a lower portion of the first article to be opened; a lower housing in which the lower handling portion is provided; and an upper housing in which a cap handling portion is provided, wherein a supporting pole is provided in one of the upper housing or the lower housing and a guide member is provided in the other of the upper housing or the lower housing, and a guide hole for guiding the supporting pole is formed in the guide member, the supporting pole being inserted through the guide hole and thereby the upper housing and the lower housing are capable of sliding up and down to each other. 5. The cap opening apparatus as claimed in claim 1, further comprising: a friction pad; a supporting portion which supports the friction pad in the upper housing with the friction pad capable of rotating on a predetermined plane surface; and a handling portion which handles the friction pad in the lower housing, wherein the friction pad is capable of rotating on a plane surface and moving in a horizontal direction on the plane surface.
