• Staplers of this type are known (DE-A 44 47 079), which have a spring magazine, in which a magazine insert can be displaced from the operating position into the loading position relative to the base part and the cap part.
• the magazine insert which is under the action of a spring, is pressed out of the top part of its top position by pressing a push button or a button into its loading position.
• Spring specialist devices are somewhat more complex to construct than so-called upper loader rate, for which the cap part is folded around the transverse axis into a loading position opened by 180 ° and the clamp slide is taken against the spring force in the slide guide of the clamp magazine.
• the slider is retracted either via a tension spring or a pull tab.
• the cap part is under the direct or indirect action of the spring acting on the clamp slide, which tries to pivot the cap part back into its closed position.
• it is releasably latched to the base part in its opened loading position by means of a latching mechanism.
• the object of the invention is to develop a stapler of the type specified at the outset, which has a loading mechanism which is easy to handle and manufacture.
• the solution according to the invention is based on the idea that the staple magazine is connected to the base part so as to be displaceable, and that the cap part can optionally be displaced together with the magazine cover in a magazine guide and / or a bottom part fixed slide guide relative to the bottom part. With these measures it is achieved that the clip magazine for the refilling process can be opened by moving the cap part over the rear transverse axis.
• a preferred embodiment of the invention provides that the locking mechanism is designed as a latching mechanism arranged between the clip magazine and the cap part or magazine cover.
• the latching mechanism can have a button arrangement which can be operated directly or indirectly via the cap.
• the thrust guide comprises at least one guide link on the magazine side, in which the cap part and / or the magazine cover connected to it with displacement engages with at least one sliding block arranged on the driver side.
• the driver-side sliding blocks are expediently designed as pins projecting laterally beyond the magazine cover, which engage in the guide slots of the clip magazine, which are open toward the inside.

• Head part 20 of the insertable driver 30 insertable cap part 32 of the clip magazine.
• the clip magazine 22 is overlapped by a magazine cover 34 against which the cap part is supported by a spring 36 which is integrally connected to the driver 30 in the exemplary embodiment shown.
• the driver 30 is together with its spring 36 positively anchored to a cap-side driver holder 38.
• the clip magazine 22 is connected to the bottom part 14 so as to be displaceable, while the cap part 32 together with the magazine cover 34 takes the clip slide 28 and the spring 26 from an operating position (FIG. la) in a loading position relative to the clip magazine 22 and to the bottom part 14 in a loading position (Fig. 1b).
• the staple magazine 22 can be refilled with staples from above.
• the spring 26 is clamped between the magazine cover 34 and the clamp slide 28 in the manner of a tension spring in such a way that when the cap part 22 and the magazine cover 34 are closed, the clamp slide 28 is carried along by the spring 26 in the direction of the head part and against the clamps located in the magazine the headboard presses.
• the spring 26 is free of prestress, so that the cap part remains in its loading position even without a locking mechanism.
• a push guide 40 is provided.
• the slide guide 40 comprises two guide links 44, which are arranged in mirror image to one another in the side flanks 42 of the clip magazine 22, into which the magazine cover 34, which is fixedly connected to the cap part 32, engages, each with a link block 46 arranged on the driver side.
• the guide links 44 each have a parallel to the direction of displacement th displacement section 48 and an end section 50 oriented perpendicularly to this and parallel to the ejection direction of the driver 30.
• the displacement section 48 merges into the end section 50 via a locking curve 52.
• the displacement sections 48 are formed by two grooves in the side flanks 42 of the clip magazine 22 which are open towards the inside of the magazine and also serve as a slide guide 24 for the clip slide 28.
• the magazine cover 34 is raised over the cap part 32 at the driver end so that the latching cams 56 disengaged from the latching recesses 54 and the sliding blocks 46 in the end sections 50 of the guide slots 44 are lifted over the latching curves 52 and moved into the shifting sections 48 will.
• the latching cams 56 come out of the engagement area with the side flanks 42 of the clip magazine into an area above the upper edges 58 of the side flanks 42.
• the slide guide 40 furthermore has two guide links 62, which are arranged on the side flanks 60 of the cap part 32 and are designed as inwardly open grooves and are arranged in mirror image with respect to one another, into each of which a bottom guide arranged at a radial distance from the transverse axis 16 partially engages guide cam 64.
• the guide elements 62 on the cap part side have a displacement section 66 aligned parallel to the direction of displacement and a pivoting section 68 connected to the latter, which is formed concentrically to the transverse axis 16 in the operating position of the cap part 32.
• the flanks 70 of the guide link 62 facing the transverse axis 16 are interrupted by a gap 72 in the transition region between the sliding section and the pivoting section 68 for reasons of assembly and are open towards the transverse axis 16 against the direction of displacement.
• the latter enables the cap part 32 to be displaced across the transverse axis 16. Since the transverse axis 16 is located outside and the guide cams 64 are located within the flanks 70 of the guide link 62 in each displacement position between the operating position and the loading position, the cap part 32 is locked against pivoting in the displacement position.
• the driver-side sliding blocks 46 and the locking cams 56 also contribute to this blocking.
