In this type of apparatus, first, a staple is pushed out by grasping a lever, the leg portion of the staple is pierced through the sheet, and then the lever is depressed, thereby lowering a sheet receiving tray for placing the sheet to bend the staple leg. It is like that.

[0003]

However, in such a system, a regulating member is provided below the paper receiving tray for holding the paper receiving tray at the raised position, and the lever is depressed. The member is slid to allow the paper receiving table to descend. Therefore, in order to slide such a regulating member, a separate slide member and a mechanism for sliding the slide member are separately required, so that the number of parts is increased, and downsizing is required. In a stapler,
There was a problem that the assembly became difficult.

[0004] Therefore, an object of the present invention is to provide a binding device capable of assembling more easily by devising a slide member for restricting the lowering of the paper receiving table. It is.

[0005]

That is, the present invention provides a holding member for holding consumables for binding paper sheets, a handle member for ejecting consumables held by the holding member, and In a binding device having a deformable table for deforming a consumable, and a paper receiving table provided to be able to move up and down with respect to the deformable table, the holding member is provided with a restricting portion for restricting the lowering of the paper receiving table. The restricting portion is slid together with the holding member in accordance with the closing operation of the handle member to allow the paper receiving table to descend.

In such a configuration, for example,
Providing a protruding portion inside the handle member, providing an inclined piece having an inclined portion on the holding member, making the protruding portion contact the inclined piece with the closing operation of the handle member, and sliding the regulating portion together with the holding member. If the lowering of the paper receiving table is allowed, it is not necessary to separately provide a new slide member as in the related art, and the number of parts can be further reduced.

Preferably, if such a holding member is provided as a cartridge detachable from the main body, it is not necessary to mount the slide member in a small place as in the conventional case, and the manufacturing process can be further shortened. Will be able to do it.

[0008] When the holding member is slid in this manner, the consumable to be ejected also slides, so that the relative positional relationship with the ejection member for ejecting the consumable is shifted. Therefore, in order to prevent such a problem, it is preferable to slide the holding member having the restricting portion after the consumables are ejected.
