Abstract: A user sets a function of corner stapling, two-point stapling or punching on an operation panel of a copying machine, as a process for a paper after copying. Then, the copying machine determines whether or not a function of folding the paper after copying is set, for setting a position for corner stapling, two-point stapling or punching on a portion suitable for each folding method. The user can set the paper folding function and the stapling or punching function in a combined manner, and the facility of the copying machine is improved.

Abstract: An image forming apparatus is capable of performing a plurality of processes for a sheet provided with an image such as stapling and punching. When two different processes are set together, the image forming apparatus displays a particular screen for making a user select positions for these processes. Thus, the incidence of setting errors can be reduced when the user sets the two processes in combination with each other.

Abstract: An image forming apparatus capable of simultaneously performing an image forming operation of a first job and an image reading operation of a second job wherein the jobs comprise a plurality of sheets. The apparatus has a controller which continues the image reading operation of the second job even when the image forming operation of the first job is stopped, and prohibits the start of an image reading operation of a third job different from said first and second job when the image reading operation of said second job ends.

Abstract: A telephone line interface section, which has a selector switch for selectively connecting two of a facsimile section, a telephone line and an information unit such as a personal computer, is provided. The telephone line interface section is provided with a telephone line monitor which detects an ON/OFF state of a start switch for directing the facsimile section to be operated and detects existence or non-existence of a DC loop current which is a connecting signal at the time when the facsimile section is connected to an external telephone switchboard via the telephone line. The selector switch connects the facsimile section to the information unit based upon the telephone line monitor when the start switch is in the ON state and the connecting signal is not detected. As a result, in the case where the facsimile section is used as a scanner and printer of the information unit, the facsimile section can be simply connected to the information unit.

Abstract: An instrument for chemical and microbiological tests comprises a sample container for temporarily storing a liquid sample; a plurality of sample-holding portions formed on the bottom face of the sample container; and a liquid-absorbent body capable of coming in contact with the liquid sample so that the body can absorb the excess sample, when the liquid sample is introduced into the container, while retaining the sample to be held on the sample-holding portions. This instrument can be used in a chemical or microbiological test wherein a sample is used in a relatively small amount and, in particular, those requiring a large number of reactions and cultivation. Moreover, the instrument does not require the dispensation of a sample to each reaction system and does not cause any scatter of the sample in the surroundings.

Abstract: Each of first and second lenses, which are in meniscus forms with concave surfaces opposing each other, is made as a plastic lens having at least one aspheric surface, and the whole lens system has a three-sheet lens configuration, thereby achieving a smaller size and a lower cost, while making it easy to restrain focus from fluctuating upon changes in temperature. Disposed successively from the object side are a first lens L.sub.1 in a low-power meniscus form made of a plastic having a convex surface directed onto the object side, whose both surfaces are aspherical; a second lens L.sub.2 in a low-power meniscus form made of a plastic having a concave surface directed onto the object side, whose both surfaces are aspherical; and a third lens L.sub.3 in a meniscus form made of a glass with a positive refracting power having a convex surface directed onto the object side.

The distance between the image side of the surfaces of second and third lens elements is made greater than or equal to 3.4 f, and less than or equal to 7.5 f, where f is the focal length of the image-forming lens, so as to minimize spherical aberration, coma, and astigmatism. The image-forming lens thus formed is a retro-focus lens having a half-picture angle of about 80.degree. and an F# of about 1.8.

Abstract: The invention provides a document editing apparatus by which a hand-written inputted editing operation can be reflected on a document without deterioration of the efficiency in editing operation. Editing operations recognized by an editing operation recognition section based on locus data, that is, information hand-written inputted using a locus data inputting section, are stored once into an editing operation storage section. Each time an editing operation is inputted, an editing operation which satisfies a determination condition stored in a determination condition storage section is searched from among the editing operations stored in the editing operation storage section by a determination section. Then, only the editing operation thus searched out is reflected on the document by a document editing section.

Abstract: A copying machine according to the present invention having a multi-job function can perform processing to a current job and a sub job, and errors are divided into two stages. If a high level error occurs in a job processed as the sub job, the job is switched to the current job, and the error is widely displayed on the entire display portion. If a low level error occurs in a job processed as the sub job, the error is displayed in a small sub job display portion in the display. As a result, the user can be accurately informed of an error occurring in the sub job in the copying machine.
