  • Patent number: 9003875
    Abstract: A sheet thickness detection apparatus includes a bracket, a power device, a first linking lever, a second linking lever, a sheet pressing part, and a sensing device. The bracket has a base with a perforation. The sensing device includes a supporting part and a sensor. The power device, the first linking lever, the second linking lever and the sheet pressing part are disposed on a first surface of the bracket. The sensor is fixed on the supporting part. When the supporting part is connected to a second surface of the base, the sensor is penetrated through the perforation and exposed to a lateral side of the first linking lever. Moreover, the supporting part is movable, so that the position of the sensor relative to the first linking lever is adjustable.

  • Patent number: 8827257
    Abstract: A sheet processing device includes a supporting plate, a stapler, a casing, a protrusion structure, and a swinging arm. The casing is disposed over the supporting plate. A sheet conveying channel is formed between the supporting plate and the casing. The protrusion structure is disposed on a lower surface of the casing, located beside the stapler and accommodated within the sheet conveying channel. During the process of introducing a sheet into the supporting plate, the stapled side of the sheet is flattened by the protrusion structure, and thus the possibility of upturning the sheet is minimized. During the process of introducing the plural sheets to the stapler, the stapled sides of the plural sheets are flattened by the protrusion structure, and thus the formation of the folded corners of the sheets is avoided.

  • Publication number: 20130234384
    Abstract: A stapling device for use with a printing device is provided. The stapling device is disposed on the printing device. The stapling device includes an exit, a conveying channel, and a channel base plate. The channel base plate is located at a bottom side of said first conveying channel. In addition, the channel base plate has a movable contact plate, which may be moved relative to the channel base plate. In a case that a paper jam event occurs within the stapling device, the user may move the movable contact plate. As the movable contact plate is moved, the jammed paper sheet is correspondingly moved to a position near the exit. Consequently, the jammed paper sheet can be easily removed through the exit by the user.
