An image recording system comprises a plurality of image recording units that can selectively be driven to achieve most efficient operation. For example, the system may also include an input unit for entering image information and a control unit for selectively supplying image information entered by the input unit to at least one of the image recording units. In this case, the input unit further includes a display for indicating an operating condition of each of the recording units. As another example, the system may include a plurality of input units and a control device for detecting, during recording by all of the recording units, a new recording requirement and designating at least one of the recording units to interrupt its current recording operation and fulfill the new recording requirement. The system may also include a plurality of storage trays, for storing sheets on which recording has been performed by the recording units, in accordance with the one of the plurality of input means through which image information has been entered by the recording units.

Disclosed is a device for detecting an incident position of radiation beam, particularly, its center or center of gravity. The detecting device is provided with a scanning type radiation beam sensing device having a plurality of radiation sensing elements in a linear arrangement, and the sensing device is disposed in such a manner that its radiation receiving surface may be substantially coincided with an incident surface of the radiation beam to be detected. When reading an output from the sensing device, the time sequential output signals from the sensing device are split into predetermined sections, and the signal quantities among the sections are compared. In this way, the position of the center or the center of gravity of the radiation beam on the incident surface is detected with the position corresponding to a split point of the signals as the reference.

In an image information recording apparatus which comprises a laser oscillator, means for deflecting and modulating the laser beam from the laser oscillator by an external signal, a recording medium, optical means for imaging the modulated laser beam on the recording medium and means for causing the laser beam to scan over the recording medium, the light path of the laser beam is divided into a plurality of light path sections and partition plates are provided before and behind each of the light path sections and have holes formed at the portions thereof corresponding to the center of the optical axis. Thus, the optical axis in the apparatus may be adjusted by passing the laser beam through the center of the holes in the partition plates.

An image forming apparatus capable of enhancing the accuracy of the scanning position of a laser beam to thereby obtain a more precise image. Optical sensors detect reflected light from a surface of a photosensitive drum. During image formation, the apparatus detects the scanning speed of the laser beam in a main scanning direction based on detection signals from the respective optical sensors in each of divisional sections of an image forming area in the main scanning direction. The apparatus corrects magnification of the image in the main scanning direction, based on results of detection of the scanning speed of the laser beam in the main scanning direction.
摘要:
A color ink jet printing apparatus including a single suction mechanism having a capping member designed to cap any one of the printheads of the apparatus and carrying out a suction recovery of that capped printhead. A plurality of additional caps which are not associated with the suction mechanism are provided for capping the printhead. Various printing moving schemes are devised to provide quick and efficient positioning of selected printheads opposing the suction mechanism to speedily service that printhead.

A hand-held recording apparatus for image recording on a recording medium by manual movement comprises a main body, a thermal head provided in the main body and having plural heat-generating elements for image recording on the recording medium, an ink sheet positioned feedable to a recording position by the thermal head and bearing ink which is transferred onto the recording medium in response to the heat generation of the thermal head, a first elastic member for biasing the thermal head to the recording medium, and a second elastic member for biasing the main body having the thermal head therein to the recording medium.The elastic force of the second elastic member is selected larger than that of the first elastic member.
摘要:
An image recording apparatus capable of recording images of two opened pages of a book-type original on the front and back sides either of one record paper or of different record papers upon receipt of a single instruction. Image data representing a first page of two opened pages of the book-type original read by a first reading unit is supplied to a recording unit, and representing image data of a second page of the original reading by a second read unit can also be stored in a memory. The recording unit record images based on the first image data and third image data which was read and stored in the memory in a previous cycle.
