According to one embodiment, an image forming apparatus includes a support shaft, a connecting member, and a detachable member. The support shaft extends in a first direction. The support shaft includes a protrusion. The protrusion protrudes in a second direction orthogonal to the first direction. The connecting member is formed of an elastic material. The connecting member interposes the protrusion therebetween. The connecting member is connected to the support shaft to surround an outer periphery of the support shaft. The detachable member is detachably connected to the support shaft via the connecting member.

An electric stretch film dispenser includes a frame and a power unit. The frame has a top seat and a bottom seat. The top seat and the bottom seat are jointly provided with a film mounting unit and a film dispensing unit. The film dispensing unit has a first roller and a second roller. The first roller is connected with a first power drive unit. The first power drive unit is configured to drive the first roller to rotate. When in use, the film of a film roll is pulled due to different rotational speeds of the first roller and the second roller. Thereby, the electric stretch film dispenser can automatically generate tension when used, so it can be used to pack articles at different heights. The electric stretch film dispenser facilitates the application of the film and increases the tension of the film.

An image reading apparatus includes a medium support section that supports a medium before feeding, a reading section that reads the medium that feeds from the medium support section, a transport roller that is disposed upstream of the reading section and transports the medium to the reading section, and a load applying device that applies a load against rotation of the transport roller. The transport roller is disposed on a rotating shaft that extends in a medium width direction that intersects the medium transport direction, and the load applying device imparts the load by pressing a transport roller driving gear that is disposed at one end of the rotating shaft in a direction from the one end of the rotating shaft to the other end thereof.

A lottery ticket dispensing unit includes at least one ticket compartment and a separation module that has a drive roller and an opposed idler roller. A motor is geared to the drive roller and is switchable between a convey mode wherein the drive roller engages and conveys a leading ticket to a separation position and a brake mode wherein the motor provides a reverse retarding force to the drive roller to brake the drive roller against an attempted reeling of the lottery tickets. from the dispensing unit. A controller switches the motor between the convey and brakes modes such that in the brake mode, power to the motor is interrupted and windings in the motor are short-circuited.

In an example, a roller lock may include a lock to engage with a roller of a feed system, and a leadscrew to engage with the lock. The lock may include a coupling to operably engage with a complementary coupling of the roller. The leadscrew may include an advancer to engage with the lock such that the advancer may translate the lock along a longitudinal axis of the roller so that the lock may engage and disengage with the roller to intermittently prevent the roller from rotating in a forward direction.

A sheet feeding device includes a cassette storage part, a sheet feed cassette, a pickup roller, a feed roller, a retard roller, a retaining member, and a pushing mechanism. The pushing mechanism pushes the retaining member so that the retard roller is pushed to contact with the feed roller. The pushing mechanism includes a pushing member that contacts and pushes the retaining member, and a biasing member that biases the pushing member. In a plane perpendicular to a rotation shaft of the retard roller, a pushing direction of the pushing member in a push contact position against the retaining member forms an angle of 45 degrees or less, with a straight line connecting the center of the rotation shaft of the retard roller and the center of a rotation shaft of the feed roller.

A film packing device capable of replacing gears includes a handle. Two ends of the handle are provided with a coupling rod and a base, respectively. A film application unit and a pair of rollers are pivotally connected between the coupling rod and the base. Two ends of each roller are provided with an axle gear, respectively. The outer toothed portions of the axle gears mesh with a drive gear and a reduction gear, respectively. The drive gear meshes with the reduction gear. Through the outer toothed portions of the axle gears to mesh with the drive gear and the reduction gear, the drive gear and the reduction gear can be installed easily. The drive gear and the reduction gear having different numbers of teeth on the outer toothed portions thereof are selective so as to change the gear ratio thereof to provide a different binding force for packing.
