Abstract:
A recording medium storage apparatus has a storage cassette and a lock mechanism. The lock mechanism restricts movement of the storage cassette in the drawing direction. The lock mechanism has an engaging portion on an apparatus body and an engaged portion on the storage cassette. While the storage cassette is drawn out of the apparatus body, an abutting portion of the engaging portion moves along a first slope on the engaged portion toward a peak portion while swinging in a second direction in which it retracts from the engaged portion, and meanwhile the engaged portion rotates in a third direction so that the peak portion is displaced from a protruding position to a guiding position.
Abstract:
An image forming apparatus includes a duplex conveying unit, an intermediate conveying unit, a duplex conveying path, a main conveying path and a locking mechanism. The duplex conveying unit turnable around its lower end is provided in an aperture of an apparatus main body. The intermediate conveying unit turnable around its lower end is disposed inside the duplex conveying unit. The duplex conveying path is arranged between the duplex conveying unit and the intermediate conveying unit. The main conveying path is arranged inside the intermediate conveying unit. The locking mechanism couples the duplex conveying unit and the intermediate conveying unit by turning the duplex conveying unit and the intermediate conveying unit in an approaching direction to each other. The locking mechanism decouples the duplex conveying unit and the intermediate conveying unit by turning the duplex conveying unit and the intermediate conveying unit in a separating direction from each other.
Abstract:
An image forming apparatus includes: a fixing section; a housing having an air inflow hole, an air outflow hole, a duct, and a fan circulating the air in the duct; and a main body frame. The duct has: (i) a first duct part extending from the air inflow hole to an arrangement region; (ii) a second duct part continuing to the first duct part and extending along the arrangement region; (iii) a third duct part extending from the air outflow hole to the arrangement region; (iv) a fourth duct part continuing to the third duct part and extending along the arrangement region at a position different from the second duct; and (v) a fifth duct part being provided between the second and the fourth duct parts and being curved in a meandering manner in a region, other than the arrangement region, located between the housing and the main body frame.
Abstract:
A sheet feeder includes a sheet feeding cassette stored in a cassette storage part, a heater and flow regulating plates. A first gap is formed between the bottom plate of the sheet feeding cassette and a bottom portion of the cassette storage part, and having an air intake port. A second gap is formed between the side plate of the sheet feeding cassette and a side portion of the cassette storage part and has a vent port communicating with the first gap and the sheet storing part. The flow regulating plates are disposed in the first gap so as to form a duct together with the sheet feeding cassette and the cassette storage part. Air flow is generated such that air is supplied from the air intake port into the first gap, is heated, rises through the second gap from the vent port, and flows to the sheet storing part.
Abstract:
A sheet feed device includes a feed unit and a sheet loading cassette. The feed unit includes a separation conveyance portion that is composed of a feed member and a separation member, a separation holder that supports the separation member and is swingable, and a pressing member that presses the separation holder. The sheet loading cassette includes a grip portion, a pressure release member that, in conjunction with an operation of drawing out the sheet loading cassette, comes into contact with the pressing member, an operation lever that is provided at the grip portion. In a state where the sheet loading cassette is inserted in the apparatus main body, the operation lever is gripped together with the grip portion, and thus the pressure release member slides to come into contact with the pressing member, so that the pressing member is released from the separation holder.
