摘要:
A device for detecting and communicating the occurrence of malfunctions occurring in an optical unit of a laser printer or the like wherein the number of terminals needed for communicating multiple malfunction-indicating signals is reduced to one. Various malfunctions are indicated by signals of respective different frequencies. The pulse width of the single signal thus composed is detected to determine in an external processor the type of malfunction.

In an automatic diaphragm stop down operation square wave pulses are generated, the number of which represents the extent of diaphragm stop down. Short pulses are generated responsive to the leading and trailing edges of the square wave pulses. The short pulses are counted. After a predetermined number of short pulses are counted, diaphragm stop down is arrested. In one embodiment, when a periodic input signal representative of the extent of diaphragm stop down rises above a first threshold, the square wave pulses are produced at a first level and when the input signal drops below a second threshold lower than the threshold, the square wave pulses are produced at a second level.

A clothing simulation apparatus precisely determines clothing pressure for bringing a clothing into tight contact with a human body. A fitting part 22 divides a paper pattern model into a plurality of elements, imparts dynamic characteristics shown by a fabric model to each element, deforms the paper pattern model by solving the motion equation of each element using a finite element method, and then fits the clothing virtually to a human body model. The fitting part 22 sets a temporary model to cover a predetermined section of the human body model, deforms the paper pattern model to bring the paper pattern model into contact with the temporary model, and thereafter deforms the paper pattern model to bring the paper pattern model into contact with the human body model.

An Internet camera system is provided with a file server connected to the Internet, an Internet camera provided with a modem, and a terminal device. The Internet camera is capable of capturing an image and converting the same into an image file. Further, the Internet camera is capable of transmitting the image file, through the modem, to the file server via the Internet. The terminal device is connectable to the Internet, and is capable of browsing images the file server stores. The terminal device further includes a transmitting system that transmits predetermined data to the file server. The file server includes a calling system that makes a call to the modem of the Internet camera when the predetermined data is transmitted from the terminal device. The Internet camera is configured to capture an image and transmit an image file of the captured image when the modem receives a call.

A thermal printer has with a cover member which swings away from the printer. A thermal line printhead is separated from a platen roller in response to the swinging of the cover member. A paper detector on the cover member swings away from the printer with the cover member. Accordingly, a single sensor detects when paper is loaded in the printer, when the cover is open, and when the thermal line printhead is separated from the platen roller, all of which result in the an interruption or prohibition of printing.
摘要:
An electrophotographic printer using a plurality of types of continuous recording forms having different page lengths, respectively, with perforations being provided between pages of each of the continuous forms. The printer is operated at least in a standby state and in a printing state. The printer comprises feed means for feeding the continuous-form recording sheet loaded into the printer, and control means for controlling the feed means in such a fashion that the perforations is located at a predetermined position when the printer is in the standby state, regardless of the page length of the recording form loaded into the printer. The predetermined position coincides either with an image-transfer position or an image-fixing position.

A horizontal sync signal generating device for use with an optical printer to determine the starting positions of horizontal scannings on a photoconductive member for forming images thereon. The generation of horizontal sync timing signals is kept constant regardless of any difference in the characteristics of a light beam transmitted via each scanning face of a polygonal rotary member.

An image organizing unit for use in a laser beam printer. The image organizing unit comprises a character generator which has a plurality of character patterns, each of which has a larger number of pattern elements a long the width direction than that corresponding to a resolving power of the printer. A main-scanning clock pulse frequency is also set to be higher than that corresponding to the resolving power of the printer. With the thus constructed image organizing unit, the printing quality can be improved, particularly for oblique lines of characters, with the resolving power of the printer remaining unchanged.
摘要:
The present invention provides an intensity control device for a laser in a laser beam printer that produces a hard copy of image information by copy-processing a photosensitive surface scanned by the laser while it is in a scanning mode during which the laser is modulated by the image information. The intensity control device according to the present invention stores a first representation of a present light intensity of the laser during its non-scanning mode. It further stores a second representations of a user selected image density for a hard copy produced by the printer. The first and second representations are combined for forming a control voltage during a non-scanning mode of the laser. Finally, a current is produced that is supplied to the laser in response to the control voltage such that the intensity of light produced by the laser is dependent on both the first and second representations.
