A device for reproducing a color on demand. The device includes a body including a tip and a scanner. The body also includes a control unit, a plurality of ink reservoirs, an ink supply system, a mixing tank and a sensor. The control unit communicates with the scanner and ink supply system to reproduce a desired color that has been scanned.

This printing device is provided with a first ink container that contains a first ink; a second ink container that contains a second ink; temperature adjusting units that adjust the temperature of the first ink contained in the first ink container and/or the temperature of the second ink contained in the second ink container; a nozzle that sprays the inks; and a control unit that controls the first temperature adjusting unit and the second temperature adjusting unit.

An electronic stylus device includes a stylus tip element having a stylus tip end and an opposing end. The stylus tip element is positioned at an end of the electronic stylus device and aligned along the long center axis of the electronic stylus device. A nutation collar is positioned about the stylus tip element and the long center axis. The nutation collar provides one or more bearing surfaces around the stylus tip element between the stylus tip end and the opposing end of the stylus tip element. The one or more bearing surfaces permit the stylus tip element to nutate within the nutation collar. A deflection sensor is positioned proximate to the opposing end of the stylus tip element on the long center axis and detects lateral deflection of the opposing end of the stylus tip element relative to the long center axis of the electronic stylus device.

The present disclosure relates to a device for activating thermochromatic ink. The device may include a drawing tip, a heating element, which may include a positive temperature coefficient (PTC) heating element, communicably coupled to the drawing tip and configure to heat the drawing tip, and a power source configured to provide power to the heating element. The power source may be a lithium-ion battery. The battery may be rechargeable, and the device may have a charging port to recharge the battery from a power source coupled to the charging port. The device may have a regulator for regulating power from the power source to the heating element. The device may have a controller for directing power from the power source to the heating element. Further the heating element may be configured to heat the drawing tip to a temperature between 30-70 degrees Celsius.

A heat pen may be used with an electronic cutting and/or drawing system to enable the electronic cutting and/or drawing system to use heat to define text and/or designs on a substrate. The heat pen may be coupled with a cradle of an electronic cutting and/or drawing system directly or by assembling an adapter with the heat pen. Power may be supplied to the heat pen by electrically coupling the heat pen to an external power supply, such as a power and/or communications port of the electronic cutting and/or drawing system. Electronic heated design systems and methods for modifying substrates using heat are also disclosed.

Various embodiments provide a position pointer that includes a plurality of refill bodies that can be configured at low cost, and ensures freedom from malfunction during exchange of signals with a sensor section of a position detection device. In one embodiment, the position pointer includes a tubular housing having an opening portion, a plurality of refill bodies, a refill body selection mechanism section that selectively causes at least a tip of one of the plurality of refill bodies to project from the opening portion, a magnetic material core, and a coil wound around the magnetic material core. The refill bodies not selected by the refill body selection mechanism section are located away from a through hole of the magnetic material core.
