  • Patent number: 8371393
    Abstract: An electric stapler is operated by a paper bundle pinching step of relatively moving a table part and a driver unit and also pinching a paper bundle; a staple separation step of folding a staple into U-shape by a forming plate and also separating the folded U-shape staple from a staple sheet by moving a driver; a penetration step of penetrating legs of the staple into the paper bundle by further moving the driver; a clinch step of inward folding the legs by a clinch device; and a paper bundle releasing step. A relative movement of the table part and the driver unit, the forming plate, the driver, and the clinch device are powered by a single motor. A driving speed of the motor in the steps excluding the penetration step and the clinch step is slower than the driving speed of the motor in the penetration step and the clinch step.

  • Patent number: 8328176
    Abstract: To provide a paper-sheet-loading device that makes it easy to take out booklet or the like loaded on a tray. The paper-sheet-loading device 1 is provided with a discharge-processing portion 7 which discharges the booklet or the like through a discharge portion and a discharged paper stacker 8 having a loading stage 80 on which the booklet or the like discharged from the discharge-processing portion 7 is loaded. The loading stage 80 is provided with a tray 81 on which the booklet or the like is loaded and which can be pulled out from the front side of the device and an auxiliary loading member 80b closing the lower side of a rear side of the tray 81 when the tray 81 is pulled out. The auxiliary loading member 80b has a shape after a loading face 81a of the tray 81 and becomes exposed continuously from the lower side of the tray 81 to the rear side thereof, thereby enabling the booklet or the like to be loaded without losing its balance.

  • Patent number: 8322940
    Abstract: A binder is configured such that a plane portion is formed on an outer peripheral surface of at least one ring part at a portion intersecting with a back part of the binder, and such that, when a binder holding member of a binding processing machine holds the binder, the plane portion of the binder contacts with a plane table provided on the binder holding member. Because the binder contacts the plane table on the binder holding member when the binder holding member holds the binder, the binder is held in such a state that the binder cannot incline or rotate. Thus, a binding processing operation can be carried out in the binding processing machine while the binder is held in a regular orientation. Accordingly, a mounting failure due to an inclined orientation of the binder and be resolved.

  • Publication number: 20100135712
    Abstract: A planar section is formed on one or a plurality of ring sections of a binder, on an outer circumference side of a portion orthogonally intersecting with a spine section. When a binder holding member of a binding machine holds the binder, the planar section of the binder is permitted to abut to a planar table formed on the binder holding member. Since the planar section of the binder abuts to the planar table of the binder holding member when the binder holding member holds the spine section, the binder is held in a status where the binder cannot incline nor rotate and binding is performed by the binding machine with a prescribed posture. Thus, a possibility of causing a mounting failure due to inclination of the binder posture is eliminated.

  • Publication number: 20080090199
    Abstract: In the field of dental care, diagnoses have been and being made by means of X-ray images, visual observation, explorer, palpation, fluorometery, insertion of a pocket probe and observation, observation by means of a root canal meter and the use of a Doppler flood flowmeter. However, such diagnoses are invasive and not very clear and three-dimensional X-ray CT apparatus that are being used for diagnoses are very large and complex. Additionally, OCT apparatus for obtaining optical tomographys by using reflection light that are being used by ophthalmologists give rise to problems because of the profile of the detection probe and operability when such an apparatus is used in an oral cavity that contains hard tissues such as teeth and soft tissues such as gingiva for dental care. The present invention dissolves the above identified problems and provides a non-invasive and high resolution dental optical diagnostic apparatus.
