Electronic underlay with wireless transmission function

Abstract

Provided is an electronic underlay with a wireless transmission function, designed not to sense a hand holding a writing tool at the time of writing on a sheet. The electronic underlay with a wireless transmission function can be laid under a sheet to perform writing with a writing tool. The electronic underlay is provided with: a sheet-like optical waveguide formed by sandwiching lattice-like cores between a sheet-like under cladding layer and a sheet-like over cladding layer; a light emitting element connected to one end surface of the core; a light receiving element connected to another end surface of the core; and wireless transmission means for wirelessly transmitting inputted letters as electronic data. An elasticity modulus of the core is larger than an elasticity modulus of the under cladding layer and the over cladding layer.

Description

TECHNICAL FIELD[0001]The present invention relates to an electronic underlay with a wireless transmission function, which can be laid under a sheet where an inspection record for equipment or an apparatus or the like is to be written, to wirelessly transmit the contents written on the sheet to a data center or the like as digital data (electronic data).BACKGROUND ART[0002]For example, in the case of inspecting gas equipment, electric equipment or the like in a house, a factory or the like, an inspector from an inspection company or the like visits a site with the presence of the equipment or the like to be inspected and performs inspection, and based on a result of the inspection, the inspector writes a check mark on each inspection item listed in a dedicated inspection record sheet or writes a comment on the sheet. Subsequently, the inspector returns to the inspection company or the like, and organizes the inspection result and arranges a necessary replacement part or the like.[000...

Benefits of technology

[0006]On the other hand, in the inspection by means of the mobile terminal, the efficiency in organization of the inspection result and the like can be improved by digitization, but the client who requests inspection cannot receive a sheet with the inspection result recorded thereon in the site. The client receives the sheet later by mail or the like.

[0012]The electronic underlay with a wireless transmission function (hereinafter simply referred to as “electronic underlay”) according to the present invention is provided with a sheet-like optical waveguide in which an elasticity modulus of a core is larger than an elasticity modulus of an under cladding layer and an elasticity modulus of an over cladding layer. Accordingly, when the surface of the over cladding layer in the optical waveguide is pressed, in a direction of the pressing, a deformation ratio of the core in a cross section is smaller than deformation ratios of the over cladding layer and the under cladding layer in cross sections, and a cross sectional area of the core is retained in the pressing direction. When a sheet is put on the surface of the over cladding layer in the optical waveguide and letters or the like are written on the sheet with a writing tool such as a pen, writing pressure by its tip (pen tip, or the like) and pressure by a portion of a hand holding the writing tool are transmitted to the over cladding layer via the sheet, and the surface of the over cladding layer is pressed. The pressing makes it possible that, at a portion pressed by the tip of the writing tool, bending of the core becomes steep along with the tip of the writing tool, and leakage (scattering) of light from the core occurs, and at a portion pressed by the portion of the hand holding the writing tool, bending of the core becomes gentle along the hand, and the leakage (scattering) of light does not occur. This then makes it possible that, as for the core pressed by the tip such as the pen tip, a light detection level (amount of received light) in a light receiving element decreases, and as for the core pressed by the portion of the hand holding the writing tool, a detection level does not decrease. A position (coordinates) of the tip such as the pen tip can be detected by the movement locus specifying means due to the decrease in the light detection level. The portion of the hand whose detection level does not decrease is in the same state as a state where it is not pressed, and it can thus be prevented from being sensed. Therefore, only a movement locus of the tip such as the pen tip (the information such as the letters having been written) can be detected. Then, the movement locus of the tip such as the pen tip can be wirelessly transmitted as electronic data by the wireless transmission means. That is, information such as letters written on the sheet can be left on the sheet and can also be wirelessly transmitted as electronic data to a data center or the like. Accordingly, for example in inspection of the equipment, an inspection record sheet with an inspection result written thereon can be passed to a client who requests inspection on the site, and the inspection result can also be efficiently organized.

Problems solved by technology

In the inspection by means of the inspection record sheet, using the inspection record sheet as a transfer sheet allows a client who requests inspection to receive a copy sheet with the inspection result transferred thereto for confirmation in the site, whereas it is inefficient for the inspector because the inspector does some work such as organizing the inspection result after returning to the inspection company or the like.
