    摘要: Sheets of recording paper are stacked and put on a push-up plate, and the uppermost recording paper is moved by pickup rollers and is separated by separation pawls. The separated recording paper is further moved by the pickup rollers so as to be carried out to the conveyance path between an upper guide and a lower guide. Notches are provided in those regions of the lower guide which correspond to the corner parts of the recording paper. Owing to the notches, the corner parts of the recording paper deformed by the separation pawls do not come into touch with the lower guide, so that the bending and jamming of the recording paper can be prevented from occurring.

    摘要: A facsimile apparatus having a housing (10) for the apparatus and a telephone placing portion (12) disposed at an upper part of the housing, on which a telephone (11) connected to a public telephone network can be placed. The facsimile apparatus further including elements (18) for scanning an original by feeding the original to generate electrical signals representing image information of the original and elements (19) for recording image information applied to the apparatus through the public telephone network on a sheet. Both the scanning elements and the recording elements are disposed side by side along the direction of feeding of the original. The telephone placing portion is disposed above both the scanning elements and the recording elements to cover the upper portion of both the scanning elements and the recording elements. The apparatus further includes a first passage (32) disposed between the telephone placing portion and the scanning elements for feeding the original and second passage (33) disposed between the telephone placing portion and the recording elements, for feeding the original passed through the first passage. Both the first passage and the second passage can be opened to the outside by opening the placing portion.

    摘要: A head driving mechanism for driving a recording head for a recording apparatus, includes a cylindrical head slide shaft, a head carriage formed with a circular bore so as to be slidably and rotatably fitted, at the circular bore, around the head slide shaft. A prismatic cam shaft which is engageable with the head carriage is also provided for rotating the head carriage, and an elastic member and a solenoid are provided for urging the cam shaft in opposite directions. Upon energization of the solenoid, the cam shaft is rotated in a direction such that the recording head is selectively depressed against a platen by a driving force of the solenoid and upon de-energization of the solenoid the cam shaft is rotated by an urging force of the elastic member such that the recording head is disengaged from the platen.
