  • Patent number: 9076451
    Abstract: An operation determination processing section of a center extracts words included in the utterance of a driver and an operator, reads an attribute associated with each word from a synonym and related word in which an attribute is stored so as to be associated with each word, reads a domain of a candidate or the like for the task associated with the attribute from the synonym and related word in which domains of a candidate for a task associated with the read attribute or domains of a task to be actually performed are stored, totals the domains read for each word for words included in the utterance of the driver or the like, and estimates those related to a domain with a highest total score as the candidate for the task and the task to be actually performed. In this manner, it is possible to estimate the task with high accuracy.

  • Patent number: 8730533
    Abstract: A document photosensor is provided which comprises a substrate 11, 12, a bracket 41, 42 disposed on substrate 11, 12 for forming a light diffusion chamber 53 and a light receiving chamber 58 separated from each other, an LED chip 21, 31 surface-mounted on substrate 11, 12 in light diffusion chamber 53, and a PD chip 37, 38 surface-mounted on substrate 11, 12 in light receiving chamber 58. These chips 21, 37, 31 and 38 are secured at precise locations on a substrate 11 and 12 with accuracy on the order of a few micrometers or less to exactly detect by PD chip 37, 38 a light irradiated from LED chip 21 or 31 after reflection of the light on a bill 50 moved along a passageway 55 to improve validation performance of bill 50.

  • Patent number: 8649069
    Abstract: A document photosensor is provided which comprises upper and lower sensor assemblies 1 and 2 disposed on opposite sides of a passageway 55 along which a document 50 is transported. Upper sensor assembly 1 comprises an upper substrate 11, an upper LED chip 21 surface-mounted on upper substrate 11 and an upper PD chip 37 surface-mounted on upper substrate 11. Lower sensor assembly 2 comprises a lower substrate 12, a lower LED chip 31 surface-mounted on lower substrate 12 and a lower PD chip 38 surface-mounted on lower substrate 12. These chips 21, 37, 31 and 38 are secured at precise locations on upper and lower substrates 11 and 12 with accuracy on the order of a few micrometers or less to exactly detect by upper and lower PD chips 37, 38 lights irradiated from upper and lower LED chips 21 and 31 after penetration of these lights through particular points on a bill 50 moved along passageway 55 to improve validation performance of bill 50.

  • Patent number: 7789211
    Abstract: A conveying device 2 in a device for validating valuable papers, comprises a rotor arrangement 5 rotatably mounted in a casing 1, a drive device 12 for rotating rotor arrangement 5, and a roller arrangement 11 disposed around and in contact to an outer circumferential surface of rotor arrangement 5. A bill 10 inserted from an inlet 8 of casing 1 is grasped between rotor arrangement 5 and roller arrangement 11 to wind up the whole length of bill 10 around rotating rotor arrangement 5 so that bill 10 can reliably be transported with rotation of conveying device 2 while preventing slippage of bill 10 on rotor arrangement 5. Also, bill 10 can be rotated together with rotor arrangement 5 one revolution or more to positively prevent unauthorized extraction of bill 10 by means of any extraction tool.
