摘要： An electrical connecting member electrically connects between two conductive members. The electrical connecting member includes a coil spring part formed by winding a wire around a coil axis. The electrical connecting member comes into contact with one of the conductive members with elastic force in a circumferential direction around the coil axis and comes in contact with the other of the conductive members with elastic force in an axial direction of the coil axis so that the conductive members are electrically connected.

摘要： An image forming apparatus includes a housing including a first wall portion extending in a vertical direction, a second wall portion extending in the vertical direction on a side opposite from the first wall portion, and an internal space formed between the first wall portion and the second wall portion. In a first state in which a sheet cassette is not attached to the housing, a cover member seals an opening portion formed in the second wall portion and through which the sheet cassette passes through, and forms part of the second wall portion. In a second state in which the sheet cassette is attached to the housing, the cover member is pivoted by being abutted by part of the sheet cassette and covers a top of a portion of the sheet cassette that is exposed to the outside of the housing.

摘要： In a sheet feeding device, a feeding roller is driven and rotated to feed a sheet in a conveying direction of a sheet conveying path and a drive transmission mechanism transmits rotation drive force generated in a driving portion to the feeding roller. In this mechanism, a drive input gear having an inner space is arranged on a rotation axis supporting the feeding roller rotatably so as to rotate by the rotation drive force. A drive transmission gear arranged between the feeding roller and drive input gear on the rotation axis rotates and becomes slide-movable along the rotation axis between a first position transmitting the rotation drive force to the feeding roller and a second position cutting off the transmission of the rotation drive force to the feeding roller by the rotation drive force from the drive input gear to transmit the rotation drive force to the feeding roller.

摘要： An image forming apparatus includes a driven unit, a coupling mechanism, a driving lever and a locking mechanism. The driven unit is configured to be supported slidably between a storage position and a pull-out position. The driving unit is driven by a driving force from a driving source. The coupling mechanism is configured to be switchable between a transmission state and a transmission release state. The driving lever is slidable between a transmission position and a transmission release position. The locking mechanism is configured to prevent the sliding of the driving lever from the transmission release position toward the transmission position. The sliding of the driving lever from the transmission release position into the transmission state can be permitted by the sliding of the driven unit from the pull-out position into the storage position.

摘要： An image forming apparatus includes an apparatus main body, a first sheet feeding cassette, a conveyance unit and a lock member. The first sheet feeding cassette is inserted into the apparatus main body along a predetermined insertion direction and is drawn out of the apparatus main body along a drawing direction opposite to the insertion direction. In a state where the lock member is in a lock position, the first sheet feeding cassette does not interfere with the lock member to allow the first sheet feeding cassette to be inserted into the apparatus main body. In a state where the lock member is in a lock release position, the first sheet feeding cassette interferes with the lock member to inhibit the first sheet feeding cassette from being inserted into the apparatus main body.
