A sheet detecting device usable with a sheet feeding device for feeding a sheet, the sheet detecting device includes a common light emitter; a first light receptor and a second light receptor for receiving the light emitted by the common light emitter and output a signal in response to the reception of the light; a first detector configured to detect presence or absence of the sheet by switching the signal outputted by light receptor, in response to the sheet blocking or reflecting the light emitted by the common light emitter; a movable portion capable of being moved by the sheet which is moving; and a second detector configured to detect presence or absence of the sheet by switching the signal outputted by the second light receptor, in response to the movable portion forming or blocking a optical path for the light emitted by the common light emitter.

The present invention relates to an accommodation container and, more specifically, to an accommodation container capable of easily and simply winding a flexible glass-bonded substrate and accommodating the same. To this end, the present invention provides the accommodation container comprising: a container body having a slit, formed at one side thereof, for providing a passage such that the flexible glass-bonded substrate having magnetism is inserted or withdrawn; and a core part rotatably formed inside the container body, formed in parallel to the slit, and winding, around the outer peripheral surface thereof, the flexible glass-bonded substrate by rotation in a state in which the end portion of the flexible glass-bonded substrate, inserted into the container body through the slit, is fixed by magnetic adsorption.

A method for processing a thin glass is provided. The thin glass is subjected to a tensile stress .sub.app smaller than $1.15.Math.\mathrm{Min}({\stackrel{\_}{}}_a-{}_{a}0.4.Math.\left(1-\ln \left(\frac{A_{\mathrm{ref}}}{A_{\mathrm{App}}}\right)\right),{\stackrel{\_}{}}_e-{}_{e}0.4.Math.(1-\ln (\frac{L_{\mathrm{ref}}}{}$

A sheet processing apparatus that is capable of facilitating a process by eliminating waste of a result even if a translucent sheet is conveyed. A conveyance unit conveys a sheet received from an image forming apparatus. An optical sensor detects a sheet end conveyed. An alignment unit aligns sheets based on information detected by the optical sensor. A post-process unit performs a post-process to the sheets aligned. An input unit inputs sheet information about a type of the sheet to be received from the image forming apparatus. A control unit stops sheet conveyance when the sheet information indicates a first type sheet and when the optical sensor cannot detect the sheet end, and continues sheet conveyance when the sheet information indicates a second type sheet of which transmittance is higher than the first type sheet and when the optical sensor cannot detect the sheet end.

A tape feeder (part feeding device) includes a main body including a transporting passage for guiding a part feeding tape to a part removing position, a conveyor for positioning a storage of the part feeding tape which is inserted to the transporting passage to the part removing position, and a part detector for detecting the part stored in the storage in the transporting passage at the upstream side of the part removing position. The transporting passage includes a travelling surface for supporting the part feeding tape from underneath, a pair of side guides for guiding two side surfaces of the part feeding tape, and a squeezed portion in which a distance between the pair of side guides is gradually reduced from the upstream side of the part detector toward a part detecting position of the part detector.
