A sheet stacking device includes a liftable/lowerable sheet stacking portion on which sheets to be ejected are stackable. The sheet stacking portion moves downward as an amount of stacked sheets increases. The sheet stacking device includes a movable member disposed below the sheet stacking portion with a space therebetween, and a detecting portion configured to output a signal in accordance with a position of the movable member. Ejection of the sheet to the sheet stacking portion is stopped on the basis of the signal output from the detecting portion in accordance with downward movement of the movable member.

An ink jet recording apparatus incorporating a plurality of ink tanks that is independently exchangeable. An amount of ink suction for a suction recovery operation is changed and controlled based on the ink tank being exchanged. In this way, a small-sized apparatus operating at a low running cost is possible by saving and decreasing the ink amount discharged by controlling the ink discharge more than necessary during the suction recovery process after exchanging the ink tank.

A liquid discharge head includes a discharge element including a discharge port, a liquid supply port, an electric connection terminal, and a heat transfer terminal. The discharge head also includes a supporting member including an electric connection terminal portion formed on a first surface thereof and electrically connected to the electric connection terminal, a heat transfer terminal junction portion formed on the first surface and connected to the heat transfer terminal, a plurality of through-holes extending between the first surface and a second surface of the supporting member, a partition wall portion separating the through-holes from each other, and a heat transfer path connected to the heat transfer terminal junction portion. An interval between the through-holes increases according to a direction from the first surface to the second surface. A volume of the heat transfer path increases according to the increase of the interval.

An optical apparatus includes a focus adjustment unit which controls a focusing lens such that the focusing lens is driven to an in-focus position using a signal obtained by photoelectric conversion of an image of an object, the image being formed by an optical system including the focusing lens; and a color temperature detection unit which detects a color temperature of the object. The manner in which the focusing lens is driven differs depending on the color temperature.

A lens barrel is configured so as to rotatably support lens barriers by a barrier drive member that rotates around an optical axis and the lens barriers rotate and revolve on an axis when the lens barriers are opened and closed. The lens barrel includes wall units provided on an inner circumference portion facing to a space where the lens barriers of the lens barrel member operates, and convexes provided on surfaces of the lens barriers adjacent to the inner circumference portion of the lens barrel member. When the lens barriers are held at a barrier opening position and the barrier drive member is moved to a driving member closing position, the wall units are brought into contact with the convexes and the lens barriers are forcibly closed.

An inkjet recording apparatus includes a head assembly in which a plurality of head chips, each having multiple nozzles arranged therein for discharging ink, are disposed in the arrangement direction of the nozzles. The discharge of ink from the nozzles of each head chip in band-boundary regions in which bands recorded by the head chips overlap each other is adjusted in accordance with the detection result of the temperature of each head chip.

An element substrate for a recording head includes groups of heating resistors that are disposed next to one another in each group; logic circuits configured to time-divisionally drive the heating resistors in units of one block; a heat enable signal line common to the groups of heating resisters, the heat enable signal line supplying a heat enable signal to each of the groups of heating resisters; and delay circuits connected to the heat enable signal line at positions between the groups of heating resisters. A signal output from each delay circuit to the next group is inverted.

A sheet conveying apparatus includes first and second conveying paths. The first conveying path is configured to receive a sheet from a device connected at an upstream side in a sheet conveying direction so as to transfer the sheet to a device connected at a downstream side in the sheet conveying direction. The second conveying path intersects with the first conveying path. A controller switches between a first operation mode and a second operation mode. In the first operation mode, the sheet is conveyed along the first conveying path, and in the second operation mode, the sheet is conveyed along the second conveying path. The controller controls a sheet conveying operation in the first operation mode or the second operation mode in accordance with the state of the sheet on the second conveying path.
摘要:
A recording and reproducing apparatus including a reproduction unit configured to reproduce information data, which is error-correcting-coded for every N tracks, from a recording medium, wherein the information data includes moving image data which is variable-length-encoded, a recording unit configured to record moving image data on the recording medium, a detection unit configured to detect additional information from the information data reproduced by the reproduction unit, wherein the additional information indicates that the editing point, which can be set up for every frame of a predetermined number, is contained in the moving image data recorded in the N tracks, and a controller configured to control the reproduction unit to reproduce the information data by transporting the recording medium at a high-speed faster than a normal reproduction speed.
