An image reading device for reading image information of an original with reading means, includes: original pressing means including a flexible sheet, a flexible member for pressing the flexible sheet, and means for pressing the flexible member.

Image reading device

During the forward driving of a recording motor, a platen roller is forwardly rotated and a de-curl shaft is rotated so as to bear against a recording sheet and at this time, a cutter is not driven. During the reverse driving of the recording motor 31, the cutter 17 is first driven to cut the recording sheet 14, whereafter the platen roller 15 is reversely driven and the de-curl shaft 27a becomes spaced apart from the recording sheet 14.

Recording apparatus

The present invention relates to an image formation apparatus comprising a first housing and a second housing which can be freely opened and closed, and in the first housing a locking nail is provided while a locking member is provided in the second housing, to which the locking nail can be hooked or released therefrom. Then, detection means is provided for the locking member in the second housing for detecting whether the locking nail is hooked or its hooking is released.

Image formation apparatus

An original feeding apparatus is structured with a first housing and second housing to enable the second housing to be opened and closed, and is provided with a feeding member for carrying an original respectively in the first housing and second housing. The original feeding apparatus according to the present invention is characterized by providing the aforesaid first housing with an original inlet for inserting an original and an original outlet for exhausting the original and at the same time, arranging the first housing to serve dually as an upper guiding plane when an original is fed while the second housing to serve dually as a lower guiding plane at the time of the original being fed.

Facsimile apparatus

An automatic sheet supplying apparatus comprising a first supply rotary member for feeding a sheet intermittently, and a second supply rotary member disposed at a downstream side of the first supply rotary member in a sheet feeding direction and adapted to feed the sheet at a stop time period shorter than that of the first supply rotary member. A clearance is created between a previously fed sheet and a next sheet.

Sheet supplying apparatus with an intermittently driven sheet separator

There is provided an image recording apparatus to record an image onto a recording sheet in a facsimile apparatus or the like. This recording apparatus comprises: a recording head for recording an image onto the recording sheet; a rotary platen roller for conveying the recording sheet; a guide member for guiding the recording sheet along the peripheral surface of the platen roller; and a device to rotatably support the guide member around the rotary shaft of the platen roller as a rotational center. The recording head is arranged so as to be come into pressure contact with the peripheral surface of the platen roller. A pair of cam members for separating the recording head away from the platen roller are attached integrally with the guide member. With this apparatus, even if the sheet holder and platen roller are closely located, the recording sheet can be easily inserted into the gap therebetween. The apparatus can be miniaturized.

Facsimile apparatus having a thermal image recording head retractable

An image reading apparatus has conveying means for conveying a sheet, a transparent member for intimately contacting the sheet conveyed by the conveying means, a photoelectric conversion element provided on or in proximity to the transparent member for reading an image formed on the sheet conveyed by the conveying means, support means for supporting the conveying means, and positioning means provided on the support means for positioning the photoelectric conversion element relative to the conveying means.

Sheet conveying and reading apparatus

A sheet conveying and reading apparatus has a conveyance path for conveying a sheet, a transparent plate for contacting the surface of the sheet being conveyed on the conveyance path, a photoelectric conversion element disposed on the transparent plate or in proximity to the surface thereof opposite to the surface of the transparent plate contacting the sheet, and a light-intercepting member for covering the side edge surfaces of the transparent plate.

Sheet conveying and reading apparatus having a light-intercepting member

An image processing apparatus such as a facsimile system has a CCD sensor for reading an original image, a detection circuit for detecting if a one-line image signal is a nearly black or white signal, a buffer memory for temporarily storing the image signal from the CCD sensor, and a microprocessor CPU for controlling the reading/recording operation in accordance with the detection result of the detection circuit. Image boundaries due to switching between reading and recording operations are eliminated from the reproduced image. A low-torque single motor may be used as a drive source in any of the transmission, reception and copying modes.

Image processing apparatus

An original reading apparatus of this invention has a platen roller for conveying an original, a solid state image sensor, a small imaging element array for forming the image of the original on the solid state image sensor, and a plate for holding down the original against the platen roller.
