A composite printing apparatus includes a character-based impact printer, a dot matrix printer, and a memory for storing a plurality of sets of pattern data corresponding to different fonts and other characteristics of print images. The impact printer includes a print element carrier having indicia identifying the font and other characteristics of the print elements on the carrier. A print carrier detector determines from the indicia the type of type elements on the carrier and generates signals for selecting from the memory a set of corresponding pattern data that is used to control the dot matrix printer to produce character images with print quality and characteristics matching those of the character images produced by the impact printer.

A key matrix circuit comprises a plurality of column lines and a plurality of row lines, a plurality of capacitance switches which are respectively arranged at different intersections of the column lines and row lines, and a select switch having a condenser, a movable contact connected to a selected one of the column lines and a plurality of change-over fixed contacts, respectively, connected to different row lines other than the row lines to which the selected column line is connected through the capacitance switches. Each of the fixed contacts is selectively connected to the movable contact and the selected column line is connected to one of the different row lines through the condenser which has an equivalent capacitance to the capacitance switches when operated. A decoder and a multiplexer are respectively connected to the row lines and the column lines of the key matrix circuit. A control circuit scans cyclically the respective conditions of the capacitance switches and the select switch through the decoder and multiplexer. As a result, a simpler circuit and method of operation are obtained.

This invention relates to an apparatus for conveying cops and bobbins for directly connecting a ring frame with a winder wherein one operation to feed those cops which are doffed onto the transport-bands on both the right and left sides of the ring frame to the subsequent process from one end of each of the transport-bands and the other operation to receive bobbins needed for the next doffing onto the transport-band are together simultaneously performed, with these two simultaneous operations being repeated. This invention has no provision of a random stock zone and the substantial function of bobbin stock is given to the transport-band, and the bobbin returned from the winder is adjusted in alignment thereof by the bobbin aligning device and conveyed by the bobbin stock conveyor and dropped onto the transport-band.

The image developing part 10 is constructed from the developing agent storing part 20 storing the fluid developing agent 18 and the developing agent supplying part 22 confronting the surface of the photosensitive drum 12 via the minute opening 25. The developing agent supplying part 22 includes a pair of, upper and lower, flat plates 24a and 24b which are placed in parallel and which define the uniform minute opening 25 over an entire width of the photosensitive drum 12. The flat plates 24a and 24b are formed with the electrodes 26a and 26b, respectively. It is possible to finely adjust the gap between the flat plates 24a and 24b through operating the minute displacement actuator 28 placed at the gap between the flat plates 24a and 24b. It is therefore possible to control the pressure to be exerted upon the fluid developing agent 18.

An article which bears information representative of a convertible value thereof is deposited by a consumer for retrieval by the manufacturer of the article. The information is represented by a bar code on the article and read by a bar-code reader. A valuable return, such as a monetary payment, to the consumer is prepared based on the convertible value represented by the information read by the bar code reader. The valuable return is actually made to the consumer based on information borne by a consumer's recording card and updated based on the information read by the bar-code reader.
摘要:
To eliminate wasteful use of thermal stencil paper and thereby provide an inexpensive stamp device, a single thermal head is employed for both the thermal recording on a reversible thermal recording sheet for confirmation of a stamp image and the thermal perforation through the thermal stencil paper for creation of a stamp original. The stamp image is first thermally recorded on the reversible thermal recording sheet; the stamp image thus recorded is then confirmed; and the thermal stencil paper is thermally perforated in accordance with the stamp image to create the stamp original. The stamp device of the present invention includes a thermal head 19, a thermal stencil paper 24 adapted to be thermally perforated by the thermal head 19 to form a dot image as a stamp image, a reversible thermal recording sheet 101 adapted to be heated by the thermal head 19 to thermally record an image corresponding to the stamp image, so as to confirm the stamp image, and a heating roller pair 90 for erasing the image thermally recorded on the reversible thermal recording sheet 101.

A light-and pressure-sensitive recording sheet and an original, overlapping each other, are introduced into an image forming apparatus, and are exposed to radiation on a transparent drum by means of a light source in the drum, whereupon a latent image, based on the contents of the original, is formed on the recording sheet. Then, the recording sheet is separated from the original by means of a separator, and is passed between a pair of pressure rolls. When the recording sheet is exposed, microcapsules thereon change their hardness. These microcapsules are ruptured selectively by pressure applied to the sheet. As a result, a chromogenic material, contained in the microcapsules, and a developer material, on the surface of a substrate of the recording sheet, react with each other, so that the sheet surface changes its color. Thus, the latent image is developed to accomplish copying in accordance with the original.
