摘要： PROBLEM TO BE SOLVED: To provide an imaging apparatus free of image defects to be generated by shocks at a cutting time when a roll-shaped recoding paper is drawn out to be image transferred and cut at the same time. SOLUTION: On a path for the recording paper 131 to reach from a recording paper holder 130 to a paper discharge opening 12, when a distance M is an integral multiple of an added length of an imaging region cutting width and a non imaging region cutting width in a travel direction of the recording paper, the arrangement is configured so that distances C and D between imaging points of imaging parts and a distance H between an imaging point of a third imaging part 123 and a cutting point of a rotary cutter part 172 hold relations of C=D=M and H=2×M.

摘要： PROBLEM TO BE SOLVED: To provide an image printer having characteristics of lesser number of parts and smaller device size in regard to image printers recording various information such as image information on recording paper. SOLUTION: This image printer is constituted by a paper discharging roller 30 conveying a recording paper 1 to the exterior of a body and a paper discharging guide 31 so that the recording paper 1 winds around the paper discharging roller 30 from an obtuse angle in a conveyance direction and a perpendicular direction. The paper discharging guide 31 has a projection protruding in a direction toward a conveyance path of the recording paper 1. The projection has a gap in a position outside an axial direction of the paper discharging roller 30 so that it does not overlap an outer circumference in a cross sectional projecting direction and an inclination of an acute angle in respect to a guide face. By this, a conveying force can be applied to the recording paper 1 by an elasticity of the recording paper 1 and members for sandwiching and conveying the recording paper 1 such as a paper discharging pinch roller are made unnecessary. Thus, a height of the body can be made lower and a number of parts can be made fewer.

摘要： PROBLEM TO BE SOLVED: To provide a superior image printer for printing images in full colors which is compact in size and can reduce costs. SOLUTION: This image printer has a switching member 10 which switches a travel course for a recording paper 2 from a paper feed part to a paper discharge part, and a guide member 19 constituted of a hard wire which is present closer to the paper discharge part than a transferring means and is shaped so that a central part is separated from a travel face of the recording paper in nearly perpendicular to a travel direction of the recording paper 2. Accordingly the apparatus is made to be compact and low-cost.

摘要： PROBLEM TO BE SOLVED: To dispose with a highly accurate guide member for mounting by fitting into a device case and a mechanism for mounting a recording paper cassette by using a stationary paper feed tray instead of a detachable recording paper cassette. SOLUTION: A paper feed tray 24 has an inclination of being higher frontward and lower innerward so that a recording paper 12 obliquely descends in a paper feed direction. A translucent cover 13 for a paper ejecting tray is opened, then a paper feed lid 22 is opened by hooking a finger by a notch in the paper feed lid and plural pieces of recording paper 12 are arranged at a specified position on the paper feed tray 24, i.e., inside a regulating part 25. The presence of the recording paper 12 can be visually determined from the front of the device through the notch in the paper feed lid 22, if the translucent cover 23 for the paper ejecting tray is closed. Further, a recessed part is provided in the front center part 27 of a recovering paper mounting part for the paper feed tray 24, so that the recording paper 12 can be easily pinched out by finger when it is unloaded. After arranging the recording paper 12, the paper feed lid 22 is closed to activate the device and the paper feed operation is initiated.

摘要： PURPOSE: To contrive size and thickness reduction of a device easily without reducing the size of main components such as thermal head and a platen roller, and ensure a good ink sheet traveling, a good mount ability, easy manufacture and a good recording paper traveling. CONSTITUTION: A supply side guide part 18 and winding side guide part 19 are provided to form passage for an ink sheet 12, by which spaces where a thermal head, a pinch roller etc., are on stand-by are generated respectively near a supply side storage part 15 on the upper side of the passage of the ink sheet 12 and a winding side storage part 16 on the lower side of the passage of the ink sheet 12, thus minimizing a retract space for setting an ink cassette at a printer device.

摘要： PURPOSE:To keep off any double-feed, feed paper slip and damage to a sheet of recording paper with less load by installing a reverse roller which presses and separates a second feed roller from the underside and handles the second sheet and after of the recording paper. CONSTITUTION:A kick-down lever 22 generates such force as winding the second sheet of recording paper 12 upside down on a reverse roller 16, producing a strong reverse feeding force there. Accordingly, even if energizing force of an energizing means 21 is set so weakly, any double feed is preventable. In addition, if the energizing force is set feebly, conveying load of the first sheet of the paper 12 is reduced, thereby making a feeding paper slip preventable too. Moreover, since a contact area between the kick-down lever 22 and the paper 12 is increased, pressure per unit area is decreased, through which any damage to the paper is made hard to be incurred.

摘要： PURPOSE:To prevent the occurrence of a double feed due to the generation of static electricity by forming a reverse roller such that its width is increased to a value higher than that of a conveying belt, and bringing a lever member to kick down second and following recording sheets into contact with the both ends of the roller from above by means of a low energizing force. CONSTITUTION:A reverse roller 30 pressing a recording sheet against a conveying belt 9 from below and handling second and following recording sheets 15b through reversing is formed such that its width is increased to a value higher than that of the conveying belt 9. The tip part of a lever member 19 to kick down second and following recording sheets 15b is rotatably located so as to make contact with the two end parts of the reverse roller 30 from above through the force of a spring 20. Thus, during completion of the feed of the sheets, the kick-down lever 19 is lowered in a sate to nip the second and following recording sheets 15b following lowering of the reverse roller 30. A first recording sheet 15a is conveyed but the second and following recording sheets 15b are pressed directly against the reversing reverse roller 30 to generate a high backward movement force, and the occurrence of a double feed is prevented.
