Description

Embodiments of the present invention relate to a sheet processing apparatus. The sheet processing device comprises a guide, a support, a stacker, and a gate. The guide has a conveying surface aligned with the sheet's conveying direction. The support, together with the guide, forms a conveying path for the sheets. The stacker has a stacking surface that supports the surface of the sheets being conveyed through the conveying path. The gate is configured to accept sheets into the stacker. If the leading edge of a sheet catches on the gate during movement, sheet jamming may occur. Japanese Unexamined Patent Publication No. 6-127782 A schematic diagram of the image forming apparatus according to the embodiment.A block diagram showing an example of the functional configuration of an image forming apparatus according to an embodiment.A schematic diagram of the sheet processing device according to the embodiment.A schematic diagram of the area around the stack inlet gate in the sheet processing apparatus of the embodiment.A perspective view showing the first and second extended portions of the gate of the embodiment.A first explanatory diagram of the operation of the support portion of the embodiment, showing the support state of the first extended portion and the second extended portion.A second diagram illustrating the operation of the support portion of the embodiment, based on the support state of the first and second extended portions.A perspective view showing the first and second extended portions of the first modified example.A perspective view showing the first and second extended portions of the second modified example. The sheet processing apparatus of this embodiment will be described below with reference to the drawings. In the following description, components having the same or similar functions will be denoted by the same reference numerals. Duplication of these components may be omitted. Figure 1 is a schematic diagram of an image forming apparatus 1 according to an embodiment. For example, the image forming apparatus 1 is placed in a workplace. The image forming apparatus 1 comprises an image forming apparatus body 100 and a sheet processing apparatus 200. The image forming apparatus body 100 and the sheet processing apparatus 200 are arranged adjacent to each other. The main body 100 of the image forming apparatus will now be described. The image forming apparatus body 100 forms an image on a sheet P (recording medium) using a recording material. The sheet P is, for example, plain paper or label paper. A specific example of the recording material is toner. The toner is either a toner used as a decolorizing recording material or a toner used as a non-decolorizing recording material. For example, the image forming apparatus body 100 is a multifunction device. As shown in Figure 1, the image forming apparatus body 100 includes a display unit 15, an operation unit 14, an image reading unit 16, a printer unit 17, a sheet storage unit 18, a paper discharge roller 19, and a first control unit 80. The display unit 15 is an image display device such as a liquid crystal display or an organic EL (Electro-Luminescence) display. The display unit 15 displays various information related to the image forming apparatus main body 100 and the sheet processing apparatus 200. The operation unit 14 has multiple buttons. The operation unit 14 receives user input. The operation unit 14 outputs a signal corresponding to the user's input to the first control unit 80 of the image forming apparatus body 100. The display unit 15 and the operation unit 14 may be configured as an integrated touch panel. The image reading unit 16 reads the image information to be read as brightness and darkness. The image reading unit 16 outputs the read image information to the printer unit 17. The sheet storage section 18 stores the sheet P used for image formation. The sheet storage section 18 supplies the stored sheet P to the printer section 17. The printer unit 17 forms an image on the sheet based on image information generated by the image reading unit 16 or image information received via the communication channel. The printer unit 17 includes an image forming unit, a transfer unit, and a fixing device. The image forming unit forms an electrostatic latent image on the photoreceptor drum based on the image information. The image forming unit forms a visible image by attaching toner to the electrostatic latent image. The transfer unit transfers the visible image onto the sheet. The fixing device heats and pressurizes the toner to fix the visible image onto the sheet. The paper discharge roller 19 is positioned near the paper discharge opening of the image forming apparatus body 100. The paper discharge roller 19 feeds the sheet P on which the image has been formed to the sheet processing apparatus 200. Figure 2 is a block diagram showing an example of the functional configuration of an image forming apparatus 1 according to an embodiment.
