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

In an original image reading device of this invention, a reading unit for reading an image on an original, an original convey unit for conveying the original, and a drive force transmission unit for transmitting a drive force from an apparatus main body to the original convey unit are integrally arranged on single support unit, so that the device is attachable to and detachable from said apparatus main body.

Image reading device and image information processing apparatus

An original image reading device includes a first supporting device having an original platen roller, provided on a side of an original opposed to an image reading device, for conveying the original at a position deviated from an original reading position, and a non-cylindrical original contact device for urging the original toward the image reading device. The original contact device is provided at the original reading position on the side of the original opposed to the image reading device. A second supporting device includes the image reading device, which has a contact-type reading sensor. The image reading device reads image information of the original by receiving a light reflected from the original. The first supporting device and the second supporting device are combined at a fulcrum at an original exit side so as to relatively rotatable. The original platen roller is separated from the second supporting device upon relative rotation of the first and second supporting devices.

Apparatus for improving illumination in a photoelectric conversion device having a light source for illuminating an original, and at least one photoelectric conversion element for receiving light reflected from the original includes a light guide for guiding light from the light source to the original, the light guide having at least one side surface. A correction section is provided and is disposed adjacent the side surface of the light guide. The correction section acts to suppress total reflection of at least a portion of the light emitted from the light source. Preferably, the correction section comprises regularly spaced light absorbing or light diffusing elements formed on the side of the light guide. The improvement apparatus may be employed in an information processing apparatus such as a facsimile machine.

A recording device comprises a plural number of ink jet device units, each unit comprising an ink jet head portion, its drive controlling portion and a wiring portion, juxtaposed on a common base plate.

Recording device

An ink jet recorder comprises a first tank as an ink supply source, a second tank as an ink supply source for the first tank, and three switching means and a pump arranged in an ink supply path. By controlling the open/close states of the switching means and operation condition of the pump, a print mode, supply mode, pressure mode, circulation mode or store mode can be selectively established.

A linear element array with n functional elements disposed one-dimensionally is constructed of a linear element array section having N blocks each having m functional elements, and a wiring section having m electrical wirings disposed side by side; wherein each of the functional elements is connected to a corresponding one of the electrical wirings by means of wire bonding.

Linear element array with wire bonding arrangement

A capping device for an ink jet recorder is provided with a support frame of substantially L-shaped cross-section contained in a frame and supporting an ink absorbing member inside thereof, and a throttle plate in contact with the underside of the absorbing member and disposed substantially parallel to the support frame, the capping device being so disposed that the rear end edge of the throttle plate opposite to a recording head is situated vertically below the side edge surface of the recording head. The specification also discloses an ink jet recording apparatus having such capping device. (FIGS. 1 and 6-8). A flow path for directing liquid squeezed from the absorbing member has upper and lower stages, the upper stage having a sufficiently large diameter that a liquid meniscus does not form and the lower stage having a small diameter that permits a meniscus to form. (FIGS. 9 and 10).

Ink jet recording apparatus and capping device

An ink jet recording apparatus has a recording head for discharging ink and effecting recording, a recording flow path communicating the recording head with one end of a first ink tank, a pump side flow path communicating the first ink tank with the recording head through a pump and, together with the recording flow path, constituting an ink circulation path through the head and the first ink tank, and a secnd ink tank for supplying ink to the first ink tank. Normally open electrical opening-closing means (FIG. 11) are provided in the recording flow path and in a tube for opening the first ink tank to atmosphere. Another normally open electrical opening-closing means and a check valve permitting the passage of ink from the pump only to the recording head, this latter opening-closing means and the check valve being interposed in series in the pump side flow path between the pump and the recording head. The apparatus also may include an overflow sensor (FIGS. 9 and 10) for detecting the amount of ink that has overflowed from the first ink tank and a water hammer damper (FIG. 14) that absorbs fluid shocks in the pump side flow path. The second ink tank may have excised portions (FIGS. 15, 16 and 18) to ensure that color ink tanks are properly mounted to the apparatus.

Ink supply device and an ink jet recording apparatus having the ink

A temperature control system for an ink jet printer has a plurality of head units each having a heater and a temperature sensor, and a fan for cooling the plurality of head units in which the fan has a heat transfer coefficient represented by a gradient of a first line connecting a maximum heat generated by heads corresponding to a sum of heat generated by the head units and heat generated by said heaters and a maximum operable temperature of said printer, and said heaters each has a heat transfer coefficient represented by a gradient of a second line connecting said maximum heat generated by the heads and a minimum operable temperature of the printer.
