Patent JP-H01210375-A (JP)
Title: Automatic stamp
Inventor: HIRAGA IMAO
IPC: B41K3/10
Filed: 1988-02-19
Abstract: PURPOSE:To reduce a load on a motor and increase reliability by providing a transmission construction to which no torque is applied with the help of holes and dowels in the relationship between a printing belt and a belt drive wheel of an automatic stamp which automatically stamps a specified label in year, month, day and time. CONSTITUTION:Guide holes 2-a, 3-a, 4-a, 5-a and dowels 6-a, 7-a, 8-a, 9-a are provided on printing belts 2, 3, 4, 5 and belt drive wheels 6, 7, 8, 9 and the reliability of belt driving is increased by the combination of holes and dowels. In this way, the hole and dowel design eliminates the necessity to apply tension to the printing belt, and allows transmission of the torque to the printing belt from the belt drive wheel. Consequently, a load resting on the belt drive wheel can be eliminated and thereby the reliability of quality increased. Furthermore, the elimination of application of tension to the printing belt leads to the prevention of the printing belt from expanding and contracting due to environmental changes such as temperature, and the subsequent stabilization of a position for a printing part.
