Abstract

A staple removing device configured to remove a staple of a paper bundle bound by the staple includes a loading portion on which the paper bundle is loaded and a pressing member ( 120 A) configured to press the paper bundle to the loading portion. The pressing member ( 120 A) includes a staple support portion ( 126 ) configured to position the staple at a removing position at which the staple abuts against the staple support portion ( 126 ).

First claim

The invention claimed is:

1. A staple removing device configured to remove a staple of a paper bundle bound by the staple comprising:
a housing including a loading portion on which the paper bundle is loaded, the loading portion being located in an upper surface portion of the housing;
a pressing member disposed above the housing, configured to be movable toward the housing, and configured to press the paper bundle loaded on the loading portion to the loading portion by moving toward the housing; and
an insertion member disposed below the paper bundle, configured to be movable along a forward direction and a rearward direction of the housing while tilting upward, and configured to abut against the paper bundle and slide by moving in the rearward direction of the housing to remove the staple from the paper bundle,
wherein the pressing member is configured to press the paper bundle from a rear side of the insertion member, and
wherein the insertion member is configured to remove the staple from a front side of the pressing member.

2. The staple removing device according to claim 1 ,
wherein the pressing member comprises a staple support portion configured to position the staple at a removing position at which the staple abuts against the staple support portion and a paper support portion at a position which opposes the insertion member via the paper bundle.

3. The staple removing device according to claim 2 ,
wherein the staple support portion is provided in an edge portion on a downstream side in an advancing direction of the insertion member in an opening portion formed in the pressing member.

4. The staple removing device according to claim 2 ,
wherein the paper support portion extends toward the staple support portion from an edge portion on an upstream side in an advancing direction of the insertion member in an opening portion formed in the pressing member.

5. The staple removing device according to claim 2 comprising:
a switch configured to allow the insertion member to advance to the position between the paper bundle and the staple; and
an operation portion which is variable between a first state where the pressing member is pressed down and the paper bundle is pressed by the pressing member and a second state where the switch is turned ON by further pressing down the pressing member from the first state and an advancement of the insertion member is started.

6. The staple removing device of claim 2 , wherein the insertion member is configured to move toward the staple support portion to a position at which the insertion member is inserted between the paper bundle and the staple.

7. A staple removing device configured to remove a staple of a paper bundle bound by the staple comprising:
a loading portion on which the paper bundle is loaded, the loading portion comprising a loading surface;
a pressing member configured to press the paper bundle to the loading portion, the pressing member including a pressing surface facing the loading surface such that the paper bundle is pressed between the pressing surface and the loading surface; and
an insertion member configured to move to a position at which the insertion member is inserted between the paper bundle and the staple,
wherein the pressing member comprises a staple support portion configured to position the staple at a removing position at which the staple abuts against the staple support portion and supports the staple in a direction opposing movement of the insertion member.
