摘要： PURPOSE:To certainly detect the presence of a recording sheet without increasing the number of parts by forming a reflecting surface having an angle different from that of the guide surface of the recording sheet at the predetermined position of a frame body. CONSTITUTION:A recording sheet presence sensor 48 is constituted of a reflection type optical sensor and the light from the light emitting element of the sensor 48 is reflected from the recording sheet 1 passing between the edge part oblique surface 27e2 of the window 27e formed to the second housing 27b and the oblique surface 6g formed to an apparatus oblique surface 6g formed to an apparatus main body 6 to reach a photodetector. That is, the surface of the light emitting element of the sensor 48 and the surface of the recording sheet 1 guided by a guide member 31 become almost parallel and, when there is no recording sheet 1, the light from the light emitting element is reflected from the edge part oblique surface 27e2 of the cartridge D and the difference between the quantity of the reflected light and that from the recording sheet 1 is detected on a voltage level to detect the presence of the recording sheet 1. The sheet guide member 31 is not bonded to the reflecting surface 27e3 reflecting the light from the light emitting element of the sensor 48 impinting against the cartridge D and the angle of inclination of the reflecting surface 27e3 is made different from that of the other edge part oblique surface 27e2.

摘要： PURPOSE:To make it possible to keep the recording density uniform by changing the carrying quantity of an ink sheet to a recording medium in response to recording density and/or recording speed. CONSTITUTION:It is checked that image to be recorded is image by standard mode, or image by fine mode, or image by super-fine mode. This can be discriminated during transmitting/receiving process of a facsimile signal. When multi- print is indicated by a switch 103a, a recording paper 11 is carried in the direction shown by arrow (a) by a quantity of 1/n of one line. The change of such (n) value can be performed by changing a step number of a ink sheet carrying motor 25 by a control signal 142. By operating a recording paper carrying motor 24 in the step S8, the recording paper 11 is carried by a quantity for one line in the direction shown by arrow (b).

摘要： PURPOSE:To improve positioning accuracy easily by performing positioning by means of a positioning member, when an ink cartridge is loaded to a recorder, and arranging first and second winding members and a guide protrusion approximately on a line. CONSTITUTION:Under a state where an ink sheet cartridge A is loaded to a recording cover 11 of a body 10, a bearing 8, U-grooves 4c, 4d and a guide pin 4e are arranged such that the centers of the guide pin 4e of the ink sheet cartridge A and the bearing 8 fitted in the U-grooves 4c, 4d lie substantially on a line. Consequently, when the ink sheet cartridge A is rotated around the guide pin 4e, the bearings 8 of a feed reel 2 and a winding reel 3 are fitted and positioned simultaneously with the U-grooves 28b, 28c of a positioning member 28. When the centers of the groove 28a2 at a key type groove part 28a and the U-grooves 28b, 28c made in the positioning member 28 are also arranged substantially on a line, the bearing 8 can be positioned accurately with respect to the guide pin 4e.

摘要： PURPOSE:To enable use of both thermal recording and thermal transfer modes and shorten recording time when a medium for thermal recording is used by changing the number of thermal dots from a thermal head depending on the processes of recording using a medium for thermal recording and of thermal transfer recording using an ink sheet. CONSTITUTION:A roll paper 10 consisting of recording sheet 11 is stored so that the sheet 11 is supplied to a thermal head part 13 when the device is set to thermal transfer mode. On the other hand, the thermal recording sheet 10 is supplied to the thermal head 13 when the device is set to the thermal recording mode. A platen roller 12 transports the recording sheet 11 and presses an ink sheet 14 and the recording sheet 11 between the roller and a thermal element 132 of the thermal head 13. The sheet 11 where an image is recorded by the heat of the thermal head 13 is transported in the direction of a discharge roller 16, then is cut using a cutter 15 and is discharged when the device is set to the thermal transfer recording mode, the ink transferred from the ink sheet 14 to recording sheet 11 and an image is recorded there. When the device is set to the thermal recording mode, the thermal recording sheet 11 becomes colored to record an image. When an image is recorded on the thermal sheet, the number of dots which become heated simultaneously by the drive of the thermal head 13 is increased to cut the recording time short.

摘要： PURPOSE:To enable recording of a clear image by applying tension on an ink sheet and transporting it using a friction force between the ink sheet and a recording medium and the loading action of a loading device which applies load on the ink sheet during the transport of a recording medium. CONSTITUTION:A torque limiter is provided on the end of the shaft 86a of a transmission gear 86. The torque limiter 85 is for example, set so that a constant load is applied on the shaft of an ink sheet supply roll 17. Consequently, an ink sheet roll 17 changes its diameter in accordance with the feed of an ink sheet 14 from the start of its use to the termination of its use. Therefore, the tension applied on an ink sheet 14 increases gradually. Thus a sag in the ink sheet is eliminated and prevented from generating.

摘要： PURPOSE:To enable slack of an ink sheet to be removed by a method wherein when loading a loading part of the ink sheet is detected by a detection means, and a specific amount of the ink sheet is carried by an ink sheet drive means. CONSTITUTION:Whether a cartridge 71 exists or not is detected with a cartridge sensor 72. When the cartridge 71 exists, rotation of an ink sheet carrying motor 25 is started, and an ink sheet winding roll 18 is subjected to rotational drive. Then, whether an ink sheet feed roll 17 is rotated or not is examined based on a signal from an ink sheet sensor 19. When the rotation of the ink sheet feed roll 17 is detected, and the rotational drive of the ink sheet carrying motor 25 is stopped. Thus by necessary minimum rotational drivie of the ink sheet winding roll 18, slack of an ink sheet 14 in the cartridge 71 is thoroughly removed, and necessary tension is given to the ink sheet 14.
