Patent number: 9956787Abstract: According to one embodiment, a laser recording device performs recording by irradiating a recording medium with laser light. The recording medium includes thermal recording layers including thermal materials with different color development threshold temperatures and stacked in an ascending order of the threshold temperatures of the included thermal materials from a surface irradiated with the laser light; and an intermediate layer provided between the thermal recording layers to perform thermal insulation and thermal conduction. The laser recording device includes a controller. The controller sets a power density of the laser light and an irradiation time and performs recording on the thermal recording layers by controlling irradiation with the laser light. The power density is relatively higher at recording of any of the thermal recording layers with a higher threshold temperature.Type: GrantFiled: March 7, 2016Date of Patent: May 1, 2018Assignee: Kabushiki Kaisha ToshibaInventors: Nobuki Nemoto, Fumitoshi Morimoto, Takahisa Nakano, Shota Kure, Takashi Yamaguchi

Patent number: 9936093Abstract: An image reading apparatus includes a sensor, a light source, and an image-capture controller. The sensor has a sensitivity area that is in a predetermined wavelength band, and acquires an image signal in accordance with light from sheet. The light source has a first light emitting unit that emits first light having a wavelength within the sensitivity area of the sensor, and a second light emitting unit that emits second light that has a wavelength which is outside of the sensitivity area of the sensor and that excites a fluorophore applied on the sheet. The image-capture controller irradiates the sheet with the first light and the second light to acquire a first image signal using the sensor, and irradiates, after acquiring the first image signal, the sheet with only the second light to acquire a second image signal using the sensor.Type: GrantFiled: March 9, 2016Date of Patent: April 3, 2018Assignee: Kabushiki Kaisha ToshibaInventors: Shota Kure, Teruhiko Uno
