To facilitate permeation of water when water is applied to the crimping range of a sheet made of a water-permeable paper material. A binding unit applies water to placed sheets and then crimp-binds the sheets. The binding unit includes a pair of pressure teeth (pressure teeth and receiving teeth part) provided on both the front and back sides of the sheets and configured to crimp-binding the sheets, a water reservoir provided on the back surface side of any one of the pressure teeth and configured to store water to be applied to the sheet, and a pressurizing member (piston) that pressurizes the water in the water reservoir to apply water to the sheet crimping range.

According to one embodiment, a sheet binding device includes a first mounting part, a second mounting part, and a mounting adjustment part. The first mounting part mounts a tape on an edge part of a sheet bundle. The second mounting part is opposite to the first mounting part in a sheet bundle thickness direction. The mounting adjustment part is capable of adjusting a mounting gap between the first mounting part and the second mounting part based upon a thickness of the sheet bundle. The mounting gap is equal to or smaller than the thickness of the sheet bundle before the sheet bundle is inserted between the first mounting part and the second mounting part.

According to one embodiment, a sheet binding apparatus includes a first roller, a second roller, and a nip-pressure adjusting section. The first roller attaches a tape to an edge portion of a sheet bundle. The second roller is opposed to the first roller in the sheet bundle thickness direction. The nip-pressure adjusting section is capable of adjusting, on the basis of the position of an edge portion leading end of the sheet bundle, a pressing force of a nip formed by the first roller and the second roller. Before the sheet bundle is inserted between the first roller and the second roller, an interval between the first roller and the second roller is equal to or smaller than the thickness of the sheet bundle.

Personalized printed products are produced in which at least one individually printed sheet is combined with conventionally printed sheets. A plurality of stacks of conventionally printed sheets are made available. In addition, a print material web is made available that contains individual sheet segments and respectively one marking based on information received from a database, or a roll is provided which contains a pre-printed material web containing the sheets segments with respective markings. The markings on the individual sheet segments are read out and information read from the markings is used for selective gathering of conventionally printed sheets that are needed for the personalize printed product. Following the readout of the markings, individually printed sheets are cut from the print material web. Respectively at least one individually printed sheet is supplied to the associated, conventionally printed sheets, corresponding to the information read from the marking from the one individually printed sheet.

A binding apparatus includes: a set of binding parts configured to press and bind a bundle of recording materials from one side and a remaining side in a thickness direction; a first support part configured to support the bundle of recording materials from the one side by performing rotation toward the bundle of recording materials around a predetermined fulcrum; and a second support part configured to support the bundle of recording materials from the remaining side so as to face the first support part when binding is performed by the set of binding parts.

A binding apparatus to bind sheets includes a binding device, a non-volatile memory, and control circuitry. The binding device is configured to bind a plurality of stacked sheets with a binding member. The non-volatile memory is configured to store a quantity of binding members in the binding device. The control circuitry is configured to control operation of the binding device. The control circuitry outputs an alert when the quantity of binding members stored in the non-volatile memory is equal to or less than a first predetermined value and cancels the alert when the quantity of binding members is equal to or less than a second predetermined value.

In a stapling device, a first guide member and a second guide member are disposed one by one on both sides of a binding portion of the recording medium on a side of a recording medium placing of a placement table such that each of the guide members is rotatable, and the first guide member and the second guide member are rotatable between a first posture along a first direction in which one abutting end side extends and a second posture inclined with respect to the first direction in line symmetry with respect to an imaginary line that passes through the binding portion along a second direction orthogonal to the first direction.
