A press structure for a press type stationery, having a mounting board (1), a button (400) and a resilient piece. A front upper end of the mounting board is recessed with a recess (11). A position limiting block (12) is provided at the front surface of the mounting board in this recess. A closed loop sliding track is formed between outer walls of the position limiting block and inner walls of the recess. The resilient piece has a spring (2) and a resilient rod (3). The position limiting block has a first inclined surface (122) and a second inclined surface (123) inclined towards the same side. End portions of lower ends of the first and second inclined surfaces are at one side of the resilient rod; upper ends of the first and second inclined surfaces are at another opposite side of the resilient rod. A contact part (4) positioned within the sliding track is provided at an end portion of an upper end of the resilient rod. The press structure makes use of the positional relationships between the resilient rod, the position limiting block and the position fixing slot so that the contact part may rely on the resilience of the resilient rod alone to achieve sliding in the sliding track. The press structure has a long service life and is easy to be configured.

Multifunction writing instrument comprising a body extending in an axial direction and housing at least two retractable writing elements and a ring portion movable in rotation. The ring portion having at least as many pairs of guide surfaces as retractable writing elements. The writing elements include buttons. Each button is configured to cooperate with a respective one of the pair of guide surfaces of the ring portion. Actuation of the button of a writing element facilitates movement of the writing element from the retracted position to the writing position and returns any of the other writing elements in the writing position to the retracted position, whereby at most, one writing element is in the writing position.

A writing instrument, in particular a pen, comprises a housing comprising a front barrel and a rear barrel, the front barrel having a front opening, two or more cartridges for storing colorants or inks, each cartridge having a writing tip, at least one actuator for selectively moving one of the cartridges within the housing so that the writing tip of a selected cartridge extends through the front opening of the front barrel, and a cartridge guide member which is designed to guide the movement of the cartridges within the housing. The front barrel and the cartridge guide member are designed to be removed from the rear barrel for replacing one or more of the cartridges. In particular, the front barrel and the cartridge guide member may be removed from the rear barrel while the cartridge guide member may remain mounted to the front member at the same time.
