Abstract: The present invention provides an ink jet recording apparatus in which many components in a carriage-driving system are unitized into a carriage frame. The apparatus comprises a carriage loaded with a recording head for discharging ink from a plurality of nozzles, a carriage-driving device for driving the carriage, a bendable electric wire, and a carriage frame. The electric wire is bent from an apparatus body and mounted to the recording head and passes a printing signal to the recording head. The carriage frame arranges the carriage, the carriage-driving device, the recording head, and the electric wire at predetermined positions to form a unit. The carriage can reciprocate in parallel with the main scan direction along the longitudinal direction of the carriage frame. As a result, the recording head can be easily replaced, and the apparatus can be maintained without complicated work.

Abstract: An inkjet recording apparatus includes (a) a carriage, (b) a recording head mounted to the carriage, (c) a transferring machine for transferring a recording medium, (d) a driving machine for operating the transferring machine, (e) a driving-force-transmitting-machine disposed between the transferring machine and the driving machine, and for transmitting the driving force of the driving machine, (f) a rotary detector mounted to a rotating shaft of any one of rotating members constituting the driving-force-transmitting-machine, and disposed within the height of the driving-force-transmitting-machine, and (g) a detecting sensor for detecting a rotating angle of the rotary detector. In this structure, even if other members hit an element of the driving-force-transmitting-machine, they never hit the rotary detector. Thus the rotary detector is prevented from being damaged or deformed due to shocks.

Abstract: An ink-jet recording device according to the present invention includes: a paper supply tray arranged inward of a predetermined face of a main body to supply recording sheets; a paper display tray arranged inward of the same face as the paper supply tray to receive recording sheets discharged after recording; an ink cartridge loading unit, which is arranged inward of the same face as the paper supply tray, and into which an ink cartridge containing ink used for recording is loaded detachably; and a controller which disables removal of the ink cartridge during a removal inhibited period.

Abstract: The disclosed alloy with a shape memory effect and a pseudo-elasticity exhibits a thin-plate martensitic structure, which alloy is made by heating an alloy consisting of 32-34 wt. % of nickel, 3-6 wt. % of titanium, 10-15 wt. % of cobalt and the remainder of Fe to a temperature between 900.degree. C. to 1,200.degree. C. and effecting an aging treatment at a temperature between 500.degree. C. and 800.degree. C. so as to generate a thin-plate martensite.
