Abstract: A vehicular interior lighting device includes a main body portion fixed to an inside surface of a roof, a light source accommodated in the main body portion, a light shielding cover portion constituting a housing with the main body portion and covering the light source from below, and a light guide member having a protruding portion protruding along the inside surface from a gap between the main body portion and the cover portion. The light guide member has a diffusion portion formed on a surface of the protruding portion facing downward and diffusing light, a first light guide portion guiding light emitted from the light source to the protruding portion, and a reflecting portion reflecting light guided by the first light guide portion toward the diffusion portion.

Abstract: A vehicular interior lighting device includes a main body portion fixed to a roof, a first light source and a second light source accommodated in the main body portion, a light shielding cover portion covering the first and second light sources from below, a light guide member having a protruding portion protruding along the inside surface from a gap between the main body portion and the cover portion, and a condensing lens disposed between the second light source and the light guide member. The light guide member has a diffusion portion formed on a surface of the protruding portion facing downward and a reflecting portion reflecting light emitted from the second light source toward a part of the diffusion portion. The diffusion portion emits light in whole by light emitted from the first light source and partially emits light by light emitted from the second light source.

Abstract: In order to reduce power consumption while an incoming call is detected by each of a plurality of communication methods, a mobile phone includes a radio circuit, a wireless LAN circuit, and a control portion to control power supply to them. The control portion cuts off power supply to the radio circuit when communication for a call by the wireless LAN circuit is established when power is supplied to both the radio circuit and the wireless LAN circuit.

Abstract: In order to simplify the operation during a call, a communication terminal includes: a radio circuit and a wireless LAN circuit; a flash ROM storing user identification information for identifying a target to communicate and telephone book data in which the user identification information and multiple pieces of access information respectively corresponding to the radio circuit and the wireless LAN circuit are associated with each other; and a control portion to search the telephone book data, if the wireless LAN circuit becomes incommunicable with the other party's mobile phone during communication, to extract a mobile phone number which is related with the user identification information of the user of the other party's mobile phone and corresponds to the radio circuit, and to originate a call to the other party's mobile phone by the radio circuit using the extracted mobile phone number.
