A printer includes an apparatus main body, an inner door unit, a main body gear, a transmission gear, and a lock mechanism section. The lock mechanism section locks the inner door unit against the apparatus main body and unlocks the inner door unit from the apparatus main body. The lock mechanism section includes a counter-engagement shaft which is long in a Y-direction, a lock lever having an engagement surface configured to engage with the counter-engagement shaft, and a tension spring that applies force to the lock lever to enable the engagement surface to change in position from a first posture to a second posture. In a closing operation, the engagement surface changes position to the second posture while shifting the position of contact with the counter-engagement shaft, and applies, to the counter-engagement shaft, a pull-in force for moving the inner door unit to a closed position.

An object of the present disclosure is to provide a conveyance apparatus whose detection unit of a printing medium is unlikely to be damaged. One embodiment of the present invention is a conveyance apparatus including: a first guide that is fixed to a main body; a second guide capable of moving to a position at which the second guide forms, together with the first guide, a conveyance path through which a printing medium is conveyed and a position at which the second guide opens the conveyance path; a first lever that is provided to the main body and which detects whether or not the printing medium exists in the conveyance path; and a second lever that shields light, wherein the first lever and the second lever can swing integrally or independently in accordance with the position of the second guide.

A web material dispenser for housing two or more rolls is provided. The web material dispenser includes a housing having a fixed housing portion provided with a first roll support assembly coupled thereto for supporting a first roll of web material. The housing further has a movable housing portion, movable between a closed position and an open position, provided with a second roll support assembly coupled thereto for supporting a second roll of web material. The fixed and movable housing portions defining a housing chamber therebetween when the movable portion is in the closed position, for at least partially enclosing the two or more rolls of web material within the housing chamber. The movable portion is moved to the open position for providing access to the two or more rolls and allowing replacement of at least one of the first and second rolls.

A sheet conveyance apparatus includes a first guide plate, a second guide plate, an operation portion provided on the second guide plate, a holding portion configured to hold the second guide plate at a second position, a door being provided to be pivotable between an open state and a close state, a releasing portion configured to abut with the operation portion on the second guide plate positioned at the second position along with a move of the door from the open state to the close state and release the second guide plate held by the holding portion, a pressing portion configured to press the operation portion such that the second guide plate is positioned at a first position, a retraction portion configured to retract the pressing portion from a moving locus of the operation portion in moving the second guide plate from the first position to the second position.

While the first opening and closing member is moved from the first closed position to the first opened position, a force transmitted to the second opening closing member by the first member interfering with the second member pivots the second opening and closing member from the second closed position toward the second opened position. While the first opening and closing member is moved from the first opened position to the first closed position, the second member retracts from the movement locus of the first member by interference of the first member with the second member, and the first opening and closing member is configured to move to the first closed position in a state where the second opening and closing member is positioned at the second closed position.

A support frame for a sheet conveying apparatus includes a bottom plate that includes a first member having a first surface portion and a first wall portion and a second member having a second surface portion and a second wall portion, a support rod that is fixed to the bottom plate, and a plurality of installation members that is fixed to the bottom plate and installs the sheet conveying apparatus. The second member is fixed to the first member by the second wall portion overlapping and being joined to the first wall portion on an outer side of the first wall portion.

A tape dispenser, including: a main body, including a base and a reel member, the reel member being connected to the base and movable between a plurality of positions relative to the base; an installation portion, connected to the main body, configured for installation of a tape; and a control portion, mounted to the base; wherein the control portion operates to allow movement of the reel member so that the reel member is switched to and restricted to be in one of the plurality of positions.

A transportation portion includes an apparatus body, a cover, first and second path formation portions, and a movement portion. The apparatus body has a transportation path including a downward path and an upward path having portions located at the same level in the Z direction. The cover covers and uncovers the transportation path. The first path formation portion is movable to a first position and to a second position. The second path formation portion defines the upward path and defines the downward path with the first path formation portion. The movement portion moves the first path formation portion in response to opening or closing of the cover. The first path formation portion is positioned in a movement area during a closed state. The movement portion moves the first path formation portion to the second position when the cover is opened and to the first position when the cover is closed.

A transport portion includes a device main body, an upper guide portion, and a lower guide portion. In the device main body, a descending path and an ascending path overlap each other in a Z direction. The upper guide portion is configured to be moved outward with respect to the device main body and is positioned above the descending path and the ascending path in a state in which the upper guide portion is stored. The lower guide portion forms the descending path and the ascending path together with the upper guide portion. The lower guide portion includes a first path forming member and a second path forming member. The first path forming member forms the descending path and at least partially overlaps a moving area of the upper guide portion at a first position and does not overlap the moving area at a second position.

A transport section includes a first roller, a second roller, a first rotating shaft, a second rotating shaft, a support unit, a main body, a door, and a third rotating shaft. The second roller nips a paper sheet together with the first roller. The first rotating shaft rotatably supports the first roller; the second rotating shaft rotatably supports the second roller. The support unit supports the first rotating shaft; the main body supports the support unit. The third rotating shaft allows the door to rotate. When the door is opened, the support unit moves the first rotating shaft to an escaped point. The escaped point of the first rotating shaft is further from the first roller positioned at the nip point than the nip point.
