An image forming apparatus includes a fixing device that has: a fixing roller heated by induction and a pressing roller brought into press-contact with the fixing roller to fix a toner image borne on a paper sheet conveyed toward the fixing device by a conveyor unit. When a paper sheet having a width smaller than a width of a maximum-width recording medium that can be passed through the fixing device is passed through the fixing device, a non-paper passing region is formed at each end portion of each of the fixing and pressing rollers. Sirocco fans cool the non-paper passing region at a part of an outer peripheral surface of the pressing roller. The pressing roller is disposed opposed to the outer side of the main body of the image forming apparatus.

A total reflection measurement method using a total reflection spectrometer 1 is a total reflection measurement method comprising arranging an object to be measured on a total reflection surface 31c of an internal total reflection prism 31 and measuring an optical constant concerning the object 34 according to a terahertz wave totally reflected by the total reflection surface 31c after passing the prism 31, wherein a liquid 50 incapable of dissolving the object 34 is interposed at least between the total reflection surface 31c and the object 34. A force such as an adhesion force acting between the liquid 50 and the object 34 can place the object 34 closer to the total reflection surface 31c, thereby stably generating an interaction between an evanescent component and the object 34.

A joining jig 5 is constituted of a pair of flat-plate sandwiching portions 17, 18 including sandwiching faces 15 which sandwich therebetween a plate member laminate 4 prepared by laminating two plate members 2, 3 with providing a solder on a joined face between the plate members. The joining jig has a plurality of vapor inflow ports provided in the sandwiching face 15 so that surplus solder vapor on the joined face flows into the vapor inflow ports in a case where the plate member laminate 4 is heated while sandwiching the plate member laminate between the pair; vapor flow paths provided so that the vapor flow paths communicate with the vapor inflow ports; and vapor discharge ports 42 provided in the side surface of the joining jig so that the vapor discharge ports communicate with the vapor flow paths to discharge the vapor of the solder to the outside.

A game machine (1) includes a game board (3) having a housing section opened on a game surface, a target which is provided to the housing section so as to freely appear and disappear, and a target driving mechanism which is provided into the game board and allows the target (9) to appear and disappear from and into the housing section. The game machine is provided with a supporting pedestal (2) which supports the game board, a rotation driving device (20) which rotates the game board supported to the supporting pedestal about a pivot axis line RC extending to a direction where the line crosses the board surface in a reciprocating manner, and a tilt giving mechanism which is provided between the supporting pedestal and the game board and gives a motion to the game board according to the rotating motion of the game board about the pivot axis line RC so that the game board tilts with respect to the pivot axis line.

An image forming apparatus includes a fixing device. The fixing device includes a heating member and a pressing member that form a fixing nip, an approach guide positioned an upstream in a recording-medium conveyance direction of a fixing nip, a fixing-pressure-changing mechanism designed to change the fixing device between a high-pressure mode and a low-pressure mode, and an approach-guide-changing mechanism designed to change an angle of the approach guide in conjunction with the changing by the fixing-pressure-changing mechanism.

A sheet feeding device for manually feeding a sheet to a specified apparatus such as an image forming apparatus is provided with a manual feed tray for guiding a sheet being manually fed, and a pair of cursors provided on the manual feed tray and movable in opposite directions along a sheet width direction normal to a sheet conveyance direction in accordance with the width of the sheet. The pair of cursors are operable such that the front end positions and/or the rear end positions thereof with respect to the sheet conveyance direction are shifted along the sheet conveyance direction.

Provided is a checking apparatus for array electrode substrate, which can check an array electrode substrate in non-contact and at high speed. A probe assembly includes a plurality of electro-optic probes arranged in the staggered relation. Since this arrangement uses a plurality of (for example, eight, sixteen, twenty, forty, etc.) small electro-optic probes, it becomes equivalent to an arrangement of an elongate electro-optic probe, thereby enabling simultaneous measurement of potentials of numerous unit electrodes. Namely, because a measurement light beam is incident into each electro-optic probe and each reflection-return light is detected by a photodector, potentials of unit electrodes in a number corresponding to the number of electro-optic probes can be simultaneously measured. Since deflection of the measurement light beams in the array direction is synchronized with relative movement between the electrode arrays and the probe assembly in a direction perpendicular to the array direction, after completion of measurement of an electrode array in a certain line, next measurement of an electrode array in a next line, can be started, as a result, enabling continuous potential measurement.
