Provided is a coating film transfer tool comprising an external cassette and an internal cassette housed in the external cassette. The internal cassette includes a supply portion configured to supply transfer tape having a coating film on substrate tape. A pressing and transferring portion is configured to transfer the coating film to a film receiving surface by pressing the transfer tape against the film receiving surface, a take-up portion is configured to take up the substrate tape after the coating film is transferred, and a rotation-in-conjunction mechanism is configured to rotate the supply portion and the take-up portion in conjunction with each other. The external cassette includes a button and an elastic member. The pressing and transferring portion sticks out of the external cassette by the button being pressed, and the pressing and transferring portion retracts into the external cassette by the pressing of the button being stopped.

A retractable writing instrument includes a push member including a clip and a protruding and retracting mechanism that causes a pen point to protrude from and retract into a front end of the barrel at a frontward press on the push member, without the push member rotating with respect to the instrument. The protruding and retracting mechanism includes cam teeth and cam grooves formed in an inner face of the barrel, a rotary member including protuberances engageable alternately with the cam teeth or the cam grooves, a cam member connected to the push member and includes cam projections rotating the rotary member, and engagement projections engaged with the cam grooves in the inner face of the barrel so as to be movable in the longitudinal direction; and a resilient element that biases the writing element rearward. The push member and the cam member are in detent engagement with each other.

A writing instrument between a first end and a second end including a writing element configured to transition between a non-writing state and a writing state, a first housing member oriented about at least a portion of the writing element and extending between the first end and the second end of the writing instrument, and an actuator configured to be moved between a first position and a second position, wherein the writing element is configured to transition from the non-writing state toward the writing state when the actuator moves from the first position toward the second position, and the writing element is configured to transition from the writing state to the non-writing state when the actuator moves from the second position toward the first position.

A writing instrument may include a barrel having a longitudinal axis, a cartridge, a writing tip, a self-retracting system for sliding the cartridge inside the barrel between a first position wherein the writing tip extends outside the barrel and a second position wherein the writing tip is retracted, the system comprising a button configured to move the cartridge between the first and the second position, and a sealing member configured to be actuated between a closed position closing a writing passage of the writing instrument, wherein the self-retracting system further comprises a linkage that connects the button and the cartridge, the linkage being configured to convert an actuation of the button into a linear motion of the cartridge along the longitudinal axis.

A writing instrument may include a barrel having a longitudinal axis, a cartridge, a writing tip, a self-retracting and sealing system for sliding the cartridge inside the barrel between a first position wherein the writing tip extends outside the barrel and a second position wherein the writing tip is retracted, the system comprising a button configured to move the cartridge between the first and the second position, and a sealing member configured to be actuated between a closed position closing a writing passage of the writing instrument, wherein the cartridge is configured to actuate the sealing member to the open position when the cartridge is moved to the first position and to allow the sealing member in the closed position when the cartridge is in the second position.
