A screening method for a substance acting on a maintenance of the epithelial properties of cells which enables obtainment of highly-reliable data quickly at low costs is provided. The screening method includes (a) a step for culturing cells on a cell culture substrate that can form a spheroid, (b) a step for causing the cells to contact a test substance, and (c) a step for evaluating an effect of the test substance acting on a maintenance of the epithelial properties of the cells with a change in a morphology of the spheroid being as an indicator. In this case, the step (c) can carry out an evaluation through a measurement of the number of spheroids in a predetermined size or a measurement of the hypoxic areas in the spheroid.

A roll paper cutting device is attachable to the main body of an image forming apparatus main body. The roll paper cutting device includes a cutter for cutting the paper of a roll of paper contained therein, as well as an arrangement for feeding the cut sheet to the image forming apparatus. The roll paper cutting device has at least one transport roller for transporting the roll paper, as well as a drive system for driving the transport roller, and a drive change device such as a clutch for selectively bringing the transport roller into idle rotation or into a driven state. A detector detects the travel of the roll paper. A control device such as a CPU controls the rotation of the transport rollers with predetermined timing based on the time when the travel of the roll paper is detected with all the transport rollers in idle rotation in a standby state for paper feeding.

An electrostatic copying apparatus having a document holding device and a semi-automatic document feeding and discharging device provided on the top of a housing. The semi-automatic document feeding and discharging device includes a main frame structure mounted for free turning between an operating position and a non-operating position. When the main frame structure is held at the operating position, a document conveying passage having an introducing section, a main section and a curved discharging section is defined. The semi-automatic document feeding and discharging device further comprises a document conveying mechanism for conveying a document to be copied through the document conveying passage, a first regulating member located in the introducing section for regulating the position of the document, a second regulating member located near the downstream end of the main section for regulating the position of the document, and a control means for the document conveying mechanism and the first and second document-position regulating members. The document holding device comprises a document holding member and a mounting mechanism therefor. The mounting mechanism includes a support member mounted for free oscillation and upward and downward movement, and the document holding member is pivotally mounted on the support member.

A cleaning device for use in an electrostatic copying machine removes with a blade any residual toner from a photosensitive body after a toner image has been transferred therefrom to a sheet of copying paper. A support shaft supports the blade for slidable contact with the photosensitive body and has a horizontal axis extending perpendicularly to a direction of travel of the photosensitive body. The support shaft is angularly movable about the axis and is axially movable. A rotational shaft is rotatable about an axis parallel to the support shaft. A first device converts rotational movement of the rotational shaft into reciprocal movement along the axis of the support shaft. A second device converts rotational movement of the rotational shaft into reciprocal angular movement of the support shaft. A third device releases interconnection between the rotational shaft and the first and second devices.

A video content edition support system is provided which includes an imaging device (2) to record captured video content data to a recording medium (14), an editor's terminal unit (4) to display video content data transmitted from the imaging device (2) and a network to connect the imaging device (2) and editor's terminal unit (4) to each other. The video content edition support system further includes a recorder to describe electronic mark data related to the video content data in the video content data, an electronic mark list generator (28) to generate electronic mark list data including header information on the video content data, and an edition unit (26) to edit the video content data on the basis of the electronic mark list data. The video content edition support system permits to select necessary video content data on the basis of the heater information in which a feature of video content data included in the electronic mark list data is described and edit the video content data directly. Information on the to-be-edited video content data is collected in the electronic mark list data.
摘要:
An image forming apparatus has an image forming apparatus main body with a sheet inlet. The main body is arranged to form an image on a sheet inserted into the sheet inlet. A roll paper cutting device contains roll paper and includes a cutting arrangement for cutting the roll paper and discharging cut sheets. The cutting device is attachable to the main body of the apparatus, and is selectively positionable to a feed position where its outlet is in register with the sheet inlet, or a standby position wherein the outlet thereof is out of register with the sheet inlet. A guide arrangement is provided on the main body for guiding the cutting device for movement in the vertical direction between the feed position and the standby position.
摘要:
An electrostatic copying apparatus which can form an image on both surfaces of a copying paper as required. The apparatus includes a copying paper conveying passage, a copying paper feeding means for feeding a copying paper sheet to the paper conveying passage, a conveyance controlling means disposed adjacent to the downstream end of the paper conveying passage, a copying paper discharging passage extending from its upstream end adjacent to the downstream end of the conveyance controlling means, a copying paper reversing passage extending from its upstream end adjacent to the downstream end of the conveyance controlling means, a copying paper returning passage extending from its upstream end adjacent to the upstream end of the conveyance controlling means, a copying paper re-feeding passage, and a copying paper re-sending means for re-sending a copying paper returned through the paper returning passage to the paper conveying passage through the paper re-feeding passage.
摘要:
A copying paper feed device for an electrostatic copier. A copying paper cassette receiving section is adapted to receive a copying paper cassette having a box-like case with a bottom plate the front end of which is biased upwardly by a spring. Within the cassette receiving section, a feed roller is mounted on a rotatable shaft that is adapted to be connected to a drive source. When the copying paper cassette is properly loaded into the cassette receiving section, the front end of the uppermost sheet of copying paper contacts the feed roller. A clutch in its operating condition links the feed roller with the drive source and in its non-operating condition permits the feed roller to freely rotate.

摘要:
A shell-type electrostatic copying apparatus comprising a lower supporting frame, an upper supporting frame mounted on the lower supporting frame for free pivotal movement between an open position and a closed position, and a unit which includes a unit frame and a rotating drum mounted rotatably on the unit frame and adapted to be detachably mounted on the upper supporting frame. A provisional unit placing means is provided in the lower supporting frame for supporting the unit frame movably. The unit is mounted detachably on the upper supporting frame by placing the unit on the provisional unit placing means, pivoting the upper supporting frame from the open position to the closed position and then moving the unit in a specified direction.
