Title: Timing mark print device
Inventor: HOZOJI MASAHIKO
IPC: B41F16/00
Filed: 1993-03-19
Abstract: PURPOSE:To execute a clear printing without occurrence of an extension at printing and with possibility of winding smoothly only necessary length of a printed tape. CONSTITUTION:A tape sending portion 58 executes a regulation of a braking power of a brake means by using a nut material adopted to the brake means through a spring. When a transfer heat plate material 56 goes down and executes a transfer, a guide means 62 migrates vertically with it, and evades contact with the transfer heat plate material 56, and a print tape 59 is so made that it is not elongated forcedly and a clear printing is executed. A print tape 59, after it is printed, can be wound smoothly at a printed tape winding portion 61 by regulating a braking power as well as a tape sending state before printing is executed.

Abstract: PURPOSE:To obtain a dimension measuring apparatus which can be handled easily, in which a measuring error is not generated and which can be used quickly by anybody by a method wherein a signal which is generated at every movement by a unit distance of a cursor along a measuring rod is counted and processed. CONSTITUTION:A measuring technique is selected by a medium-interval/small-interval lengthchangeover means 6, the criterion dimension of a tatami mat (a typical Japanese straw matting) is then selected, a cursor 4 is moved up to a criterion position, and a reset switch 7 is operated. A measuring rod 2 is placed on the tatami mat, the tatami mat is sandwiched at a right angle between its claw piece 3 and a claw piece 41 for the cursor 4, and a linear encoder 5 generates a pulse signal while the cursor 4 is moved. The pulse signal is counted by a counter circuit, a counted value which corresponds to the interval between the claw pieces 3, 41 is obtained, the counted value is converted into a dimension, and the dimension is displayed 18. Then, a length-measuring key is pressed, the displayed dimension is stored in a RAM for a signal processing circuit 10, and a display operation is continued. When the measured value is to be corrected due to the secular change of the tatami mat, a correction value is input 17, the RAM stores the dimension again, and the dimension is displayed. The operation is repeated so as to cover measuring parts, and data on the whole dimension of one tatami mat is changed into a file, stored and displayed.
