    摘要: This display device is capable of reducing possibilities of electrical disconnection between a display element and a circuit board due to a difference between the thermal expansion coefficient of the circuit board and that of a housing. Display elements (10, 20) have lead terminals (12, 22, 13). A circuit board (30) is electrically connected to the lead terminals (12, 22, 13). A housing (40) houses the display elements (10, 20). Lead guide sections (50, 60) have through holes (52, 62), through which the lead terminals (12, 22, 13) are inserted. The housing (40) has a first aligning section (43), which is aligned with the circuit board (30). The lead guide sections (50, 60) have second aligning sections (51, 61), which are aligned with the circuit board (30), and elastic supporting sections (53, 63), which are connected to the housing (40).

    摘要: A powder storage container includes a powder storage unit, a conveying member, and an elastic member. The powder storage unit stores powder. The conveying member is rotatably disposed in the powder storage unit and conveys the powder stored in the powder storage unit to an outlet. The elastic member includes: an upper end portion fixed to the inside of the powder storage unit; and a lower end portion which is a swingable free end and is disposed above the conveying member. A part of the lower end portion along the conveying direction of the conveying member is configured to contact with the conveying member to be elastically deformed.

    摘要: An image display device applies a higher voltage than the original voltage to the pixel, without causing deterioration of the display quality. The image display device includes a plurality of pixels each including a main capacitive element as a display element performing display operation in accordance with image data supplied to one end thereof. An auxiliary capacitive element has one end connected to the one end of the main capacitive element. A drive circuit drives each of the pixels, while supplying an additional potential to the other end of the auxiliary capacitive element in each of the pixels. The additional potential is individually determined so that a voltage between both ends of the main capacitive element rises higher than an original voltage.
