Abstract: With a structure in which a coupling member includes a sphere providing a center of inclination (pivoting), a rotational force transmitted member has an opening have a diameter smaller than that of the sphere, and the coupling member is prevented from disengaging from rotational force transmitted member by contact of inner edge of the opening to the sphere, the inner edge of the opening may limit an inclinable (pivotable) angle range of the coupling member. In a state that a pin that is a shaft portion is inserted in a hole that is a through-hole provided in a coupling member, opposite end portions of the pin are supported by a driving side flange, which is a rotational force transmitted member. The coupling member, the driving side flange, and the pin are connected in this manner, and the pin contacts the inside of the hole without limiting the inclinable angle range.

Abstract: A developer stirring member for stirring a developer in a developer accommodating portion includes a supporting shaft and a sheet-like member for stirring the developer. The sheet-like member has a first lateral end which is a free end and a second lateral end which is fixed on the supporting shaft. The sheet-like member is waved at the second lateral end, and waving is greater in the second lateral end than in the first lateral end. The sheet like member is fixed to the supporting shaft at intervals which are the same as pitches of the wave.

Abstract: A cleaning member is supported by a cleaning container by fastening screws with lubricant interposed between support surfaces of the cleaning container and a supporting member of the cleaning member. Accordingly, the difference in the amount of thermal expansion between the cleaning container and the supporting member generated by a change in temperature can be absorbed by sliding of the support surfaces and the supporting member relative to each other.

Abstract: The invention provides a driving circuit for a liquid crystal device having a reduced number of transistor elements by sharing transistors having identical logics among adjacent decoders. The driving circuit for a liquid crystal device capable of carrying out gradation display by applying gradation voltage corresponding to a display data to a liquid crystal element comprises a decoder circuit portion composed of a dynamic circuit for selecting the gradation voltage, the decoder circuit portion having a number of transistor elements 4 reduced by sharing transistors with identical logics constituting adjacent decoders. The voltage level corresponding to the display data causes all the analog switches to be set to an off status, so as to prevent overlap of output voltage during a timing of transition of the analog switch to the off status and a timing by which the analog switch is turned on according to a subsequent display data.

Abstract: The present invention aims to reverse and transport a card in an automated card game machine, and relates to a card reversing device that reverses and transports each card, with no one touching the card. The present invention also relates to such a card game machine and a card reversing method. Each card placed on a card placement unit of a table is pulled by the magnetic force of a magnetic circuit having three electromagnet units. Accordingly, when a slider that supports the magnetic circuit is moved by a card transportation mechanism, the card slides on the upper surface of the card placement unit as if to follow the movement of the magnetic circuit. With one end portion of the card being attracted to the center electromagnet unit, the card is reversed by 180 degrees by the repulsive force generated between the other end portion of the card and the left-side electromagnet unit.
