  • OPTICAL DETECTION DEVICE
    Publication number: 20180113024
    Abstract: A light detection device includes a Fabry-Perot interference filter, a light detector, a spacer that has a placement surface on which a portion outside a light transmission region in a bottom surface of the interference filter is placed, and an adhesive member that adheres the interference filter and the spacer to each other. Elastic modulus of the adhesive member is smaller than elastic modulus of the spacer. At least a part of a lateral surface of the interference filter is located on the placement surface such that a part of the placement surface of the spacer is disposed outside the lateral surface. The adhesive member is disposed in a corner portion formed by the lateral surface of the interference filter and the part of the placement surface of the spacer and contacts each of the lateral surface and the part of the placement surface.

  • FIXING DEVICE AND IMAGE-FORMING APPARATUS
    Publication number: 20170139373
    Abstract: An image-forming apparatus includes an image-forming unit, a fixing device including a heating rotator and a pressure member forming a nip portion together with the heating rotator, and a bias-applying unit applying bias to the heating rotator. Image forming modes each having a time interval between a preceding recording material and a succeeding recording material which is different from each other can be performed. A control unit executes a first control while the recording materials are being conveyed at the nip portion, and a second control while the recording materials are not being conveyed at the nip portion due to the time interval. A switching time in the image forming mode in which the time interval is a first time interval is determined to be longer than in the image forming mode in which the time interval is a second time interval shorter than the first time interval.
