Abstract: A state determining device includes a current detecting unit, a state determining unit, and a notifying unit. The current detecting unit detects a current value of a drive current which flows into a drive motor that rotary-drives a driven unit with a drive force according to the drive current. Based on the drive current value detected by the current detecting unit, the state determining unit determines a state of a driving system including the driven unit. The notifying unit notifies a user of a determination result of the state determining unit.

Abstract: A holder for the selected loading of a large or small cassette. A pair of positioning-restriction elements is provided inside the cassette holder at a distance enough for the small cassette to be loaded therebetween. A cassette detector detects the large cassette when it is loaded through the cassette opening. A drive mechanism moves the restriction elements from positions allowing the small cassette to be loaded to positions where the restriction elements allow the large cassette TO be loaded. A pair of flaps is positioned so that each flap is closer to the front-end section of the cassette opening than the positioning-restriction elements. The distance between the flaps allows the small cassette to be loaded therebetween. The flaps are opened so the large cassette can be loaded and they obstruct the small cassette from being loaded when at least either of the flaps is pushed by the small cassette.

Abstract: A cassette holder for a large and a small cassette to be selectively loaded. An upper surface of a frame is a part of a bottom surface of a cassette opening having a size fitting the large cassette, through which the large or the small cassette is to be loaded. A pair of positioning-restriction elements is provided inside the cassette holder when viewed from the opening provided on the front panel. The distance between the restriction elements has a width enough for the small cassette to be loaded therebetween to a predetermined position in the cassette holder. A cassette detector detects the large cassette when this cassette is loaded through the cassette opening. At least a part of the cassette detector is positioned so that it is closer to a front-end section of the cassette opening than the positioning-restriction elements are when viewed from the cassette opening.
