DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a handy labeler including a plurality of labels temporarily adhered onto a tape-like mount sheet, marks about price and date and so on being printed on the labels, and the labels being peeled off the mount sheet to adhere the label onto an article or a package thereof each time the label is printed.
BACKGROUND ART
A handy labeler is required to be smaller in size and lighter in weight than conventional ones, because it is gripped when used. However, a handy labeler has been widely used in retail stores as well as big grocery stores, it is now further required to fabricate at lower costs. In addition, as a handy labeler has been widely used, it is used in a variety of ways. Specifically, it is often used roughly, and those who are not used to handling a handy labeler use it. Hence, a handy labeler is required to be tough, and to be able to print at a certain printing concentration, even if it is used in whatever ways. To this end, there have been suggested a lot of pressure adjusting systems for printing at a certain printing concentration without being influenced by a speed of gripping of an operator. One of them is suggested in Japanese Unexamined Patent Publication No. 6171636.
However, the pressure adjusting system suggested in the Publication includes a manual lever an operator grips, an arm (manual arm), a separate part from the manual lever, for handling a printer, and a spring (impact spring) or an intermediate member disposed between them. Namely, the system is quite complicated in structure. In addition, it is necessary to make the manual lever and the arm move in synchronization with each other, and to set various conditions for forces of springs acting on the arm. It is difficult to fabricate a handy labeler so that it can withstand harsh use. Above all, the pressure adjusting system in question has a problem that it is high at costs to fabricate.
Thus, it is an object of the present invention to provide a handy labeler which is capable of providing a printing concentration sufficiently stable for practical use without problems, and has a quite simple structure.
DISCLOSURE OF THE INVENTION
The present invention provides a handy labeler including a label tape comprising a long mount sheet and a plurality of labels temporarily adhered onto the mount sheet, a printer being made to make contact with the labels from a stationary position and print on the labels in a manual lever gripping step, the printer being made to return to the stationary position and a transfer drum being made to rotate to thereby feed the label tape by one label distance in a manual lever releasing step, a printed label being peeled off the mount sheet and partially fed outside a main body, the handy labeler being characterized by: a ratchet pawl having a pawl portion and a resilient portion deformable by being compressed by the manual lever, the ratchet pawl making forward movement in a manual lever gripping step and making backward movement in a manual lever releasing step; and a ratchet wheel having a plurality of ratchet teeth including longer tooth surfaces and shorter tooth surfaces, the pawl portion making slide movement on the longer tooth surfaces towards a distal end of the tooth, when the ratchet pawl makes forward movement, the ratchet wheel being rotated by the shorter tooth surfaces being compressed by the pawl portion to thereby rotate the transfer drum, when the ratchet pawl makes backward movement, the resilient portion being deformed by the manual lever when the pawl portion is making slide movement on the longer tooth surfaces while the ratchet pawl makes forward movement, and resulting resilient force acting on the manual lever as a resistive force, the resistive force being abruptly decreased at the moment when the pawl portion exceeds the distal end of tooth to thereby cause the manual lever to make the printer make impact contact with the label. The invention makes it possible to provide constant printing concentration regardless of a speed of gripping a ma
