Abstract

A stapler that enables early recognition that staple refilling is necessary. To achieve this, the stapler has a residual staple quantity-notifying device for issuing a notice when a residual quantity of staples received in a staple magazine becomes less, and the notice is made using sound as the medium. It is constructed such that sound is produced when a pusher (13) touches at its predetermined position a driver (15), and to achieve this, the movement of a pusher (13) pushing and sending a staple into a strike out direction is used. The structure eliminates a conventional trouble of peering into a view window and frees a user from a sudden notice of stale refilling.

Description

Specification

Stapler

Technical field

The present invention relates to a stapler with a stable remaining amount notifying device for notifying a user of a remaining amount of stapling.

Background art

[0002] The basic configuration of a stapler includes a base having a curved base, a staple magazine for loading a staple insert having an ejection opening, and a handle having a driver for ejecting staples (needle) in the staple magazine from the ejection force. The rear ends of the base, the magazine and the handle are supported rotatably about an axis.

[0003] Under such a basic configuration, staples are housed in a box-shaped staple magazine, so that the remaining amount of staples cannot be confirmed during use.

[0004] Therefore, in conventional staplers, various measures have been taken so that the remaining amount of staples can be visually checked. For example, Patent Document 1 discloses a stapler provided with a slot and a display on a side surface of a stable magazine.

[0005] Further, in Patent Document 2, if a stapler is loaded into a magazine and the handle is lowered, the handle covers the magazine, and the stable in the magazine cannot be visually recognized. A stapler is disclosed in which a viewing window is provided at a position so that the power of the viewing window and the remaining amount can be visually checked.

Disclosure of the invention

Problems to be solved by the invention

[0006] In any of the conventional techniques, the remaining amount of staples is relied on visual recognition, so that it is not always possible to reliably recognize the remaining amount of staples, and that the staples in the staple magazine are empty. In some cases, it became noticeable for the first time after hitting with no air, increasing the feeling of irritation. [0007] The present invention has been made in view of the above problems, and has as its object to provide a stapler capable of quickly recognizing the necessity of a stable replenishment operation.

Means for solving the problem

[0008] In order to achieve the above object, a stapler according to the present invention has a staple outlet at a bottom end of a front end of a staple magazine, which opposes a curved table, and a pusher for pushing the staple in the direction of the outlet, Table ejection force Assuming a structure that includes a driver that ejects a staple, a staple-notch remaining amount notification device that reports sound and light as a medium when the remaining amount of staples stored in the staple magazine is low is provided. It is a thing.

[0009] According to this configuration, since a notification function using sound or light as a medium rather than visually recognizing the remaining amount is provided, it is possible to eliminate the hassle of looking through the viewing window as in the related art. This frees the user from sudden notification of refilling the staples and allows the user to perform the needle-punching operation with sufficient psychological margin.

[0010] As a means of generating sound or light in this case, a stapler generally uses staples.

Since a pusher is always provided for pushing in the direction of the ejection port, the pusher is moved so that the pusher is operated at a predetermined position by linking to a member that physically or electrically contacts the pusher. be able to.

[0011] That is, the remaining amount notifying device employs a configuration in which when the pusher reaches the vicinity of the ejection opening of the magazine, a sound or light is generated by sensing the contact with the pusher physically or electro-optically. s can.

[0012] The stable remaining amount notification device includes a bullet that generates a sound, and an engaging portion that engages with the bullet and plays it. The bullet is provided on the pusher and the engaging portion is formed on the driver so that the bullet is flipped. Then, when the stable is launched, the sound of the bullet can be used to notify that the remaining staples in the staple magazine are running low.

[0013] As another configuration of the stable remaining amount notification device, a bell member that generates a sound, a striking member that strikes the bell member, and an engaging portion that engages with and strikes the striking member may be configured. The engaging portion is provided on the pusher so that the engaging portion flips the striking member when the staple is released. An engaged portion of the striking member for engaging the joining portion is formed near the driver. This makes it possible to notify that the staples in the staple magazine are running low by the sound of the bell member when the stapler is launched.

[0014] The stable remaining amount notification device may include a sound generation unit that generates a sound, a switch that stops the operation of the sound generation unit, and an engagement unit that engages with the switch to turn on and off. A switch is provided on the pusher, and the engaging portion is formed on the driver so that the engaging portion is turned on and off by hitting the staple when the remaining amount is small. Then, when the stable is launched, the sound of the sound generating unit can notify that the remaining staples in the staple magazine are running low.

[0015] Further, a light generation unit may be provided instead of the sound generation unit, and the light of the light generation unit may be used to notify that the staples in the stable magazine are running low. In other words, the stable remaining amount notification device includes a light generation unit for generating light, a switch for stopping the operation of the light generation unit, and an engagement unit for engaging and disengaging the switch. Alternatively, a switch may be provided on the pusher so that the engaging portion is turned on and off by the ejection of the staple, and the engaging portion may be formed on the driver.

The invention's effect

[0016] As described above, according to the present invention, a stable remaining amount notifying device is provided for notifying when the remaining amount of staples stored in the stable magazine is low, and the remaining amount is visually checked. The sound and light are used as a medium for recognition instead of recognizing it, so that it is released from sudden notification of step refilling work, and it is possible to perform needle punching work with psychological margin.
