Abstract: A print device includes a supply unit, a print unit, a conveyer, a tensioner, and a rotor. The conveyer is configured to nip and to convey, with a pair of rollers, a long medium in a conveyance direction. The tensioner is configured to contact a second surface of the medium to cause the medium to bend. The tensioner is pivotably supported at a position upstream of the conveyer in the conveyance direction. The rotor is rotatably supported at a position upstream of the conveyer in the conveyance direction, and positioned downstream, in the conveyance direction, of an upstream end portion, in the conveyance direction, of the tensioner. The rotor is positioned such that an upper end of the rotor and a nipped point are at a same height. The rotor is configured to contact the second surface.

Abstract: There is provided a sheet conveying apparatus including: a casing having an opening; a cover configured to uncover and cover the opening; a holder configured to hold a roll body, the roll body including a sheet being rolled; a slidable support attached to the casing, the slidable support being configured to support the holder, the slidable support being configured to slide to an accommodated position at which the slidable support is accommodated within the casing and to a drawn position at which at least a part of the slidable support is positioned at outside of the casing with respect to the opening; and a conveyer configured to convey the sheet of the roll body in a state that the slidable support is at the accommodated position.

Abstract: A gear mechanism includes: at least one gear including a rotation shaft; and at least one bearing portion. The at least one gear can meshingly engage with another gear that applies a force to the at least one gear. The at least one bearing portion includes: a collar portion supporting the rotation shaft; and a notched portion exposing a portion of the rotation shaft to an outside. A first imaginary plane defines a first region and a second region of the at least one bearing portion. The first imaginary plane extends in an axial direction and contains a first linear line passing through a center of the rotation shaft and perpendicular to a direction of a line of action of the force. The first region is positioned downstream of the first linear line in the direction of the line of action. The notched portion is formed in the second region.

Abstract: An image forming device includes a main casing, a support member, a plurality of developing cartridges, a handle provided to the support member, and a pair of interfering parts provided at both ends of the support member. Each developing cartridge includes a casing and a developing member supported by the casing. A gap between the pair of interfering parts is narrower than a length of the developing member, and the pair of interfering parts is located between the handle and one of the developing cartridges. Each of the interfering parts has a higher height than the handle.

Abstract: A cover opening/closing mechanism, including a housing having an opening; a flexible cover movable between a closed position and an opened position; a first locking mechanism; and a second locking mechanism, wherein a first distance by which a pair of members of the first locking mechanism slide and move with respect to each other in order to bring the first locking mechanism to a locked state is longer than a second distance by which a pair of members of the second locking mechanism slide with respect to each other in order to bring the second locking mechanism to a locked state. An external force for causing the pair of the members of the first locking mechanism to slide and move with respect to each other is weaker than an external force for causing the pair of members of the second locking mechanism to slide with respect to each other.

Abstract: An apparatus includes: a main body; a supporting member having a first side wall and a second side wall, the supporting member configured to be movable between an accommodation position and a withdrawn position, the supporting member configured to be removable from the apparatus main body by being withdrawn further from the withdrawn position; a first frame facing the first side wall and a second frame facing the second side wall; a lock member configured to be movable between a lock position and a release position; and a restriction unit provided on the second side wall and the second frame, the restriction unit configured to restrict a rotation of the supporting member by coming contact with the supporting member when the supporting member, which is locked into the withdrawn position, rotates to the first frame side of the apparatus main body.

Abstract: A low cost drive transmission system provided with one-way clutch having a simple assembly and not requiring precision parts. A drive shaft 31 and a shaft 45 are connected via a link cam 30. A main cam 34 is formed on the drive shaft 31 and the link cam 30 is moved in a thrust movement along the free shaft 45 by the cam effects of the guide surfaces 50a, 50b, 53a, 53b between the link cam 30 and the main cam 34. The link cam 30 engages with an engagement pin 50 formed on the shaft 45, thus transmitting the driving of the drive shaft 31 side. Conversely, when the shaft 45 rotates faster in the advancement direction than the rotational velocity transmitted from the drive shaft 31, a thrust movement along the free shaft 45 in the opposite direction is exerted on the link cam 30 as a result of actions opposite to the above and the engagement with the engagement pin 50 is broken.

Abstract: A hand held cellular telephone system including voice storage features which enable the cellular telephone to perform functions similar to a telephone answering device, a battery monitoring system for providing the user with a real time display of the amount of time remaining for use of the cellular telephone in both the standby and conversation modes, and an interface adapter which may be used to provide speakerphone functions, power the cellular telephone, and recharge the battery.
