Abstract:
An overhead type file sheet projector including a projector body with a cover provided at an upper face opening thereof, a light source and a projecting condenser lens placed in the projector body. A support arm extends from one side of the projector body to above the projecting condenser lens with a reflecting mirror and a projecting lens system held by the support arm. A stage movably is fitted to guide rails provided at opposite sides of an upper portion of the projector body, and guide members are provided on the stage. The guide members allow movement of the file sheet in a direction orthogonal to the guide rails. A file sheet and a jacket holder for use in the overhead type file sheet projector include pitch movement cuts formed at at least one edge of the file sheet body or the jacket holder body. The pitch movement cuts are formed such that the pitch movement cuts may be engaged with a file sheet movement fitting member formed on a stage movably placed on an upper portion of the projector body.
Abstract:
A glass stage for use as an upper stage in an overhead type projector system. The glass stage includes a rectangular frame body having substantially the same dimension as that of a lower stage of a projector, a lower transparent plate fixed to the rectangular frame body, and an upper transparent plate which pushes a strip film onto the lower transparent plate. The upper plate is rotatably supported by brackets provided on the frame body. Each of the brackets is provided with a longitudinal hole which engages with hinge pins for guiding movement of the upper transparent plate in a drawing direction thereof. The longitudinal hole is provided with a portion inclined downwardly at an end of a pushing side of the upper transparent plate. The rectangular frame body is provided at one side portion thereof with small holes through which the upper stage-fitting pins are to be snugly fitted.
Abstract:
An information recording carrier-holding sheet in which laterally and vertically extending partition walls are formed in a single rigid resin sheet to form a plurality of rectangular depressions for allowing information recording carriers to be housed therein. Planar lugs are formed on the opposite side walls of each of the rectangular depression while projecting from almost the central portions of the opposite side walls in the longitudinal direction thereof to the inside of the rectangular depression. Guide members for guiding the movement of the information recording carrier in the rectangular depression are provided at the planar lugs in each of the rectangular depressions or in the vicinity thereof.
Abstract:
Disclosed herein is a film jacket for strip film comprising a surface sheet, a back sheet and a pair of locating means each consisting of at least two welded portions as a unit which are separated from each other in the width direction of the strip film at distance slightly larger than the width of the strip film, said pair of the locating means being separated from each other in the length direction of the strip film pocket and said welded portions constituting a film pocket for holding a strip film therein. The welded portions of the paired locating means on either one of the upper and lower sides of the film pocket may be united together to form a short or long welded portion which is positioned between the welded portions on the other side of the film pocket.
Abstract:
The disclosed cooling device, which is for overhead projectors adapted to project pictures of transparencies carried by a filing sheet without removing them from the filing sheet, comprises a blowing fan and an air-blowing nozzle adapted to discharge at least a part of the air from the blowing fan toward a space between a transparency in position for projection and bottom wall of the filing sheet, so as to cool the transparency and the filing sheet.
Abstract:
The disclosed structure holds a rectangular thin-piece such as a photographic transparency on a base sheet between at least two holding portions formed on the base sheet and a thin-piece seat being recessed relative to the holding portions. A push-in area is formed on the base sheet adjacent to both the seat and at least one of the holding portions. One edge of the thin-piece is once pushed in between the push-in area and the holding portion adjacent thereto to an extent sufficient for clearing the thin-piece from the remainder of the holding portions, and then the thin-piece is moved back from the push-in area onto the seat where an abutting member abutts the thin-piece to keep the thin-piece in position. A plurality of the thin-piece holding structures are formed on one base sheet to form a slide filing sheet.
Abstract:
A sheet-like storing element for storing an optical recording disc. The storing element is formed at one side with one or more rectangular frames each of which have a circular frame formed therein. In the circular frame, there is a cutout portion which is formed by cutting off a portion of an area which is surrounded by the circular frame. The circular frame is interrupted or cut-off in the vicinity of at least one of corners of the rectangular frame. The sheet-shaped storing element has a film of a flexible material which is attached thereto at a side where the circular frame is formed so that the area surrounded by the circular frame is covered thereby. The circular frame of the storing element has an inner diameter which is larger than the outer diameter of the recording disc which is to be stored in the storing element. The circular frame further has an inner periphery which is slanted radially inwardly to provide a slanted surface which functions to receive the periphery of the recording disc to thereby support the disc with a clearance with respect to other portions of the storing element. The film of flexible material is split along a split line extending in a direction of crossing the circular frame whereby the film can be turned over at one side of the split line to provide an access to the disc stored in the circular frame for taking out the disc by gripping it with fingers.
Abstract:
A file sheet binder including a plurality of binding units arranged in parallel. Each of the binding units comprises a flat, elongated base plate and one or more gripping sections, each including a pair of gripping members provided at one surface of the base plate. The paired gripping members have edges which are opposed to each other to form a slit therebetween so that a file sheet can be gripped at an edge portion by the edges forming the slit. An opening is formed in the base plate between the paired gripping members. The gripping members and the base plate are manufactured as an integral part by molding a plastics material. The opening is adapted for removing a core which is used in molding process for defining a space between the paired gripping members.
Abstract:
A recording disc filing device for storing optical recording discs such as compact discs. The filing device includes a recording disc filing sheet having a plurality of recording disc storing sections for receiving recording discs, respectively. The recording disc storing sections are arranged in a predetermined pattern. The filing device further includes a leaflet filing sheet having leaflet storing sections for receiving leaflets carrying information on recorded contents in the recording discs stored in the recording disc storing sections. The leaflet storing sections correspond in number to the recording disc storing sections. The recording disc filing sheet and the leaflet filing sheet are arranged so that the leaflet storing sections in the leaflet filing sheet are located at positions corresponding to the recording disc storing sections in the recording disc filing sheet. The leaflet filing sheet is connected along one edge portion with the recording disc filing sheet so that the leaflet filing sheet can be laid over the recording disc filing sheet in a manner that the leaflet filing sheet can be turned over to expose the recording disc filing sheet.
