A shoe cover cartridge includes two guiding arms and a plurality of shoe covers overlapped in a sequential manner to define a standby shoe cover and a subsequent shoe cover. Front and rear interlocking units are provided at front and rear sides of each of the shoe cover respectively and are slidably engaged with the guiding arms at a position that the front interlocking unit at the subsequent shoe cover is located in front of the rear interlocking unit at the standby shoe cover along the guiding arms. Therefore, when the standby shoe cover is pulled for dispensing, the subsequent shoe cover is pulled by the standby shoe to dispense the shoe covers in a sequential order.

A recording apparatus includes a carriage, a transport drive roller, and a plurality of gears. The carriage includes a recording head configured to record onto a medium. The carriage is configured to move in a movement region in a first direction and a second direction that is an opposite direction thereto. The transport drive roller is configured to transport the medium to a recording region in which the recording head performs recording. The plurality of gears are configured to transmit power of a motor to the transport drive roller. When the carriage is positioned at an end of the movement region in the second direction, at least a portion of one of the plurality of gears overlaps the carriage when viewed along a vertical direction that is parallel to a direction of gravity and overlaps the recording head when viewed along an axial direction of the transport drive roller.

A removable media tray with an adjustable rear tray extension operable by a rear media restraint. The tray extension is slidably attached to a front section of the tray via a cam having a locking arm engaged in a J-slot. When in the curved portion of the J-slot the front section and tray extension are locked together. A rear media restraint slidably latching to a track in the bottom of the tray has a locking lobe that engages with a locking notch on the cam. As the media restraint is slid toward the rear, the locking lobe initially rotates the cam moving the locking arm to the straight section of the J-slot, then the locking lobe engages with the locking notch, locking the media restraint to the tray extension. Thereafter, the media restraint and tray extension move together until the end of the J-slot is reached by the locking arm.

An image forming apparatus includes an apparatus main body and a feed device. The feed device is detachably attached to the apparatus main body and feeds a recording medium. The apparatus main body includes an image forming section and a main body frame. The image forming section forms an image on the recording medium. The main body frame supports the image forming section. The main body frame has a first positioning hole and a second positioning hole. The feed device includes positioning protrusions. When the respective positioning protrusions are fitted into the first and second positioning holes, a relative positional relationship between the main body frame and the feed device is determined.

A bobbin changing device for feeding bobbins to and/or removing bobbins from a processing device which can wind a strand-form material onto a bobbin and/or from a bobbin, wherein the bobbin changing device has at least one conveyor device, wherein the bobbin changing device has a swivel fork which is suited for feeding bobbins to and/or removing bobbins from such a processing device and for feeding bobbins to and/or removing bobbins from the conveyor device.

In some examples, printing device performance analysis may include actuating a motor to operate a first separation tire of a printing device in a first rotary direction. The first separation tire may be operable adjacent to a second separation tire rotatable in a second rotary direction that is opposite to the first rotary direction to separate physical media. Printing device performance analysis may further include actuating the motor to operate the first separation tire in the second rotary direction, and determining whether a motor torque difference of the motor between the first and second rotary directions is greater than a predetermined threshold.

A glove donning device includes a guide rack having a positioning portion, and a glove providing a connection portion at one side of the glove-wearing mouth thereof and a tear line at the junction of the glove and the connection portion. The connection portion is detachably fastened to the positioning portion of the guide rack to hand down the glove against one side of the guide rack. When the hand is wearing the glove, the guide rack holds the glove in place so that the glove will not move arbitrarily, and the user's hand can be easily and smoothly worn by the glove-wearing mouth into the glove by a one-handed movement. Then, the hand is pulled outward to tear the tear line apart, so that the glove can be easily disconnected from the connection portion. This design solves the disadvantage that conventional gloves (such as thin-film gloves) must be worn with both hands.

A spindle unit includes a swing mechanism fixed to a fixed frame, a support member swingably supported by the swing mechanism, a spindle main body and an electromagnetic brake supported by the support member. The spindle main body rotates integrally with a bobbin around which a yarn is wound. The electromagnetic brake applies a resistance to the rotating spindle main body. The swing mechanism includes a fixed attachment member fixed to the fixed frame, a swing shaft supported by the fixed attachment member, a spring, and a sensor. The spring applies a spring force to the support member in a direction opposite to a direction in which the support member swings by the tension of the yarn. The sensor detects the tilt amount of the support member when the support member swings.
