摘要： PURPOSE:To obtain a printing result with a fixed quality by suppressing the variation of the tension of an ink film for a thermal transfer printer. CONSTITUTION:The rotation of an S motor 32 for a supply side S reel 22, and the rotation of a T motor 29 on a take-up side T reel 6 are detected by pulse encoders 33 and 30, and the pulse cycles Ts and Tt are measured. By a micro-computer 50, the winding diameters Rs and Rt of the S reel and T reel are calculated based on the pulse cycles Ts and Tt, and current values Is and It in order to obtain a fixed tension in response to the winding diameters Rs and Rt are calculated, and the torques of the S motor 32 and the T motor 29 are controlled. Therefore, the torque of the motor is controlled in response to the winding diameter of an ink film of a heat transfer printer, and the tension of the ink film can be controlled to be uniform.

摘要： PURPOSE:To certainly detect the terminal of recording paper by providing a round hole to roll-shaped recording paper in the vicinity of the terminal part thereof and detecting the same by a reflection type infrared sensor. CONSTITUTION:Roll-shaped recording paper 2 is wound around a winding core 1 in predetermined quantity and the terminal part 2-a thereof is fixed to the winding core 1 by an adhesive tape 3 and a round hole part 2-b is provided to the recording paper 2 in the vicinity of the terminal part thereof. In a usual thermal transfer recording apparatus, the roll-shaped recording paper 2 is held between paper feed drive rollers 4, 5 and paper feed follower rolls 6, 7 and allowed to advance in the direction shown by an arrow A to be consumed with the advance of recording. At this time, the reflection type recording paper sensor 8 in the apparatus emits infrared rays on the light emitting side 8-a thereof and takes in the reflected light from the roll-shaped recording paper 2 on the light detecting side 8-b thereof to generate sensor output. Next, when the roll-shaped recording paper 2 is consumed and the round hole part 2-b reaches the position directly under the recording paper sensor 8, the infrared rays emitted on the light emitting side 8-a pass through the round hole part 2-b of the roll- shaped recording paper 2 and the reflected light is not incident to the sensor on the light detecting side 8-b thereof and, as a result, the output of the sensor becomes zero and the detection of the terminal of the roll-shaped recording paper becomes possible.

摘要： PURPOSE:To facilitate the replacement of an ink film by providing a member having a mechanism which engages with an engagement part on the other end of paired spools and fits the paired spools after the positional control of the spools in an axial direction, on the other end of the interior of a cassette. CONSTITUTION:Three end parts of both ends of each spool 8, 9 on the winding side and supply side of an ink film 7 are formed so that they become engaged in the same manner. Only the other one end is formed so that it becomes engaged in a different manner. In a cassette, members 2, 2', 3 which can become engaged with the engagement parts on the ends of paired spools 8, 9 and a member 4 which can become engaged with only the other end are provided. Consequently, when the spools of an ink film on the winding side and those on the feed side which are paired with the former are attached to the cassette 1, no erroneous attachment occurs.

摘要： PURPOSE:To eliminate the possibility of an erroneous use of a thermal recorder capable of both thermal transfer recording and thermal recording, by automatically switching a recording mode according to whether an ink paper enclosed in a cassette is fitted in place. CONSTITUTION:When an ink paper cassette 5 is fitted to a reel base 9 and is held by a cassette base 7 and a switch base 8, a recording mode detecting switch 10 is closed by the weight of the cassette 5 to give a command for a thermal transfer recording mode to a head 11, and thermal transfer recording is started. In the case of thermal recording, the ink paper cassette 5 is unnecessary, so that the recording mode detecting switch 10 opens to give a command for a thermal recording mode to the head 11. Then, with a thermal recording paper 18 inserted between a guide block 12 and a guide plate 13, thermal recording is performed.

摘要： PROBLEM TO BE SOLVED: To speed up sorting of query results in a database processing system capable of multiply issuing a data reading request. SOLUTION: The database processing system is configured to output requested data from a memory storing storage position information in which data and a storage position of the data are recorded in a predetermined order. In the system, necessary data is acquired from the memory by tasks which can be processed in parallel, and when a second task to be executed based on data acquired by a first task is absent, whether all of data requested by a third task executed prior to the first task is acquired is determined. When all of the data requested by the third task is completed, the data acquired by the first task is output, and when part of the data is not acquired, the data acquired by the first task is retained in a temporary buffer until all of the data requested by the third task is acquired, and thereafter the data is output.
