Description

stapler This disclosure relates to a stapler that fastens objects together with a needle. Conventionally, staplers that fasten stacks of paper or other materials by driving staples into them have been proposed. Motor-driven electric staplers are equipped with a guide to abut the leading edge of the material to be stapled. When the material is inserted into the stapler's slot by the user, the leading edge of the material abuts against the guide, causing the guide to move backward. This activates a detection unit, which generates a drive signal to operate the motor, and the stapling operation is performed (see, for example, Patent Document 1). This is a side cross-sectional view showing an example of a stapler according to the first embodiment.This is a side view showing an example of a stapler according to the first embodiment.This is a perspective view showing an example of a stapler according to the first embodiment.This is a side view showing an example of the operation of the stapler according to the first embodiment.This is a side view showing an example of the operation of the stapler according to the first embodiment.This is a side cross-sectional view showing an example of a stapler according to the second embodiment.This is a side view showing an example of a stapler according to the second embodiment.This is a perspective view showing an example of a stapler according to a second embodiment.This is a side view showing an example of the operation of the stapler according to the second embodiment.This is a side view showing an example of the operation of the stapler according to the second embodiment.This is a side cross-sectional view showing an example of a stapler according to the third embodiment.This is a perspective view showing an example of a stapler according to a third embodiment. The embodiments of the stapler described herein will be explained below with reference to the drawings. <Example of the configuration of the stapler in the first embodiment> Figure 1 is a side cross-sectional view showing an example of a stapler according to the first embodiment, Figure 2 is a side view showing an example of a stapler according to the first embodiment, and Figure 3 is a perspective view showing an example of a stapler according to the first embodiment. The stapler 1A of the first embodiment comprises a staple-feeding unit 2 for ejecting staples 10, a stapling unit 3 for bending a pair of staple legs 10re of the staples 10 ejected by the staple-feeding unit 2, a drive unit 4 for executing the stapling operation of the object to be stapled with the staples 10, and a detection unit 100 for activating the drive unit 4 upon detection of the object to be stapled. The stapler 1A has a staple-dispensing section 2 and a staple-binding section 3 that are connected so as to be rotatable relative to each other, with the connecting shaft 110 as the pivot point. The staple-dispensing section 2 and the staple-binding section 3 open and close in directions relative to and apart from the side connected by the connecting shaft 110. In stapler 1A, the side where the staple-issuing section 2 and the stapling section 3 open and close is referred to as the front side, and the side where the staple-issuing section 2 and the stapling section 3 are connected by the connecting shaft 110 is referred to as the rear side. Furthermore, in stapler 1A, the side where the staple-issuing section 2 is located is referred to as the upper side, and the side where the stapling section 3 is located is referred to as the lower side. The stapler 1A is configured to form staples 10 and then eject the formed staples 10. Before forming, the staples 10 are in a linear, elongated form. These unformed staples 10 are also referred to as unformed staples 10bf. After forming, the staples 10 have a pair of staple legs 10re extending approximately parallel to each other from both sides of a staple crown (not shown). These formed staples 10 are also referred to as molded staples 10af. Multiple unformed staples 10bf are detachably connected along a direction intersecting their extension direction. This forms a connected staple 11. The stapler 1A is equipped with a detachable cartridge 12 that houses multiple connected staples 11 stacked in a manner. The staple-punching section 2 comprises a first opposing section 20 facing the binding section 3, and a first projection 21 protruding from the first opposing section 20 toward the binding section 3. The staple-punching section 2 has the first projection 21 on its front end side, and a concave first opposing section 20 is formed on the rear side of the first projection 21. The binding section 3 comprises a second opposing section 30 facing the staple-punching section 2, and a second projection 31 protruding from the second opposing section 30 toward the staple-punching section 2. The binding section 3 has the second projection 31 on its front end side, and a concave second opposing section 30 is formed be
