摘要： PURPOSE:To prevent an image input device from being driven by a malfunction and to suppress the presentation of unnecessary information by regulating the prescribed operation of a terminal equipment as necessary. CONSTITUTION:An operation switch 16 is directly or remotely operated, a motor arranged in an original setting plate 13 is driven, a rubber rollers 14, 15 are rotated to move an original set up on the plate 13 in the A or B direction, and a required part of the original is fetched from a camera part 11. When an operation inhibition switch 4 is depressed as necessary in the case of holding a conference with a remote plate by means of this video conference system, the control of a camera 1 in a present from an opposite station can be inhibited. Simultaneously the operation of the camera 1 is inhibited and the inhibited state is displayed on a monitor. Consequently the presentation of unnecessary data can be prevented.

摘要： PURPOSE:To increase the accuracy of a recording means relative to a recording performance recovery means and enhance the recording performance to make it possible to maintain an image quality at high level constantly by making the recording means and its recording performance recovery means one integrated body and further, making this integrated body detachable from the main device system. CONSTITUTION:A recovery unit 9 for normalizing the discharge abnormality of ink due to bubbles or impurities which generate in the discharge orifice 42 of a recording head 8, is arranged at a position behind each suction orifice 10. In addition, a suction pump connected to each suction orifice is arranged in the unit 9, and decreases the inner pressure of each suction orifice 10 in a capped state. Further, the suction pump sucks bubbles and impurities from the inner part of the discharge orifice 42 of each recording means together with ink and expells them to an outside area. The suction pump is so designed as to convert a rotating drive force to a load. It is possible to replace or maintain/inspect a main scan recording mechanism and recovery means 9, 10 by detaching part with the whole main scan base 26 in the arrow direction when a serviceman or a user replaces parts or checks them for periodic maintenance service.

摘要： PURPOSE:To achieve easy execution of the jam processing even when jamming occurs in any position in the conveyance path of recording medium, by releasing the recording-medium holding force of a recording-medium conveyance means through operation of a raising/lowering mechanism and drawing out the conveyance means from the recording position to a jam processing position located outside the apparatus body When the jamming occurs in the recording medium. CONSTITUTION:When a chassis 16 supporting conveyance means 14a, 14b, 15a, 15b is moved upwards, positioning thereof is effected by positioning plates 36 to 39. The positioning plates 36, 37 are fixed to a side plate to which is mounted a main scan rail 7 for guiding a carriage 5. On the other hand, the positioning plates 38, 39 are mounted integrally to a restoration unit 10. By this, the relative positional precision between the positioning plates 36, 37 and the main scan rail 9 is ensured while the positional precision between the carriage 5 and a platen 9 and the conveyance means mounted to the chassis 16 is increased. Resultantly, it is possible to facilitate the jam processing of the recording medium and ensure the positioning precision between the conveyance means and the recording means after execution of the jam processing.

摘要： PURPOSE:To make possible to assemble an image recorder with high workability by mounting a recording sheet carrying means detachably on the machine body thereby improving the positional accuracy of each member and to facilitate removal of sheet at the time of jamming. CONSTITUTION:When a recording sheet 1 is fed from direction A and arrives at a predetermined position, a carrying motor 17 is driven to rotate rollers 13, 14 thus carrying the recording sheet 1 onto a platen 19. Subsequently, a main scanning motor 3 is driven to move a carriage 7 in direction C and an ink delivery signal corresponding to an image is fed to the ink jet head of each cartridge 8 thus forming an image with a predetermined width. At that time, main members at recording position relevant to carriage of the recording sheet 1 are assembled on a base 25 which is then slid by means of a handle 37 to abut the rear face thereof against stop boards 27, 28 thus incorporating the base 25. When a jammed sheet is removed, the base 25 is drawn out.

摘要： PURPOSE:To stick two sheets together efficiently. CONSTITUTION:A first sheet Pa and a second sheet Pb are set on a first base 1a and a second base 1b respectively by means of positioning mechanisms 10a, 10b, 13a, 13b and the sheets Pa, Pb are fixed to the bases 1a, 1b respectively. The bases 1a, 1b are positioned by means of positioning mechanisms 15, 16 to stack them on one another and hot melt adhesives interposed between the sheets Pa, Pb are melted by means of heating mechanisms 23a, 23b to stick them together.

摘要： PURPOSE:To attain accurate alignment by feeding a transducer with less number of steps till a reference position with respect to a track is detected in a feeder feeding the transducer in plural steps in the normal operation mode. CONSTITUTION:The feeding of a magnetic head 3 per one track pitch of a sheet 1 is implemented by 4 steps by a step motor 6 in the normal operation mode in a recording and reproducing device for a magnetic sheet, and a head 3 is fed to an outer or inner circumference with a feed mechanism comprising the motor 6, a rotary shaft 7, a feed screw 8, a head base 4 and a guide 9 prior to the operation mode to ensure the absolute reference position with high accuracy. That is, the reference position is detected by a reference position detector comprising a shield plate 11 and a photocoupler 12 while feeding the head 3 with the feed mechanism one by one step. Thus, the alignment accuracy at the reference position is improved.
