Title: Timer input device
Inventor: SAKAI MOTOO
IPC: D06F33/02
Filed: 1988-10-18
Abstract: PURPOSE:To eliminate mis-count due to chattering and to prevent timer mis- setting by providing an integration means integrating every time an output pulse value of a pulse encoder changes in a prescribed way and a stop means of the integration operation. CONSTITUTION:Every time a pulse encoder 101 generates an output pulse by its drive and the output pulse changes in a prescribed way, an integration means 102 applies integration. Moreover, a stop means 104 after the integration of the means 102 depending on the output pulse stops the integration of the means 102 for a prescribed time only. Thus, even if chattering takes place and the output pulse is changed at its change, since the integration is stopped, the change is not integrated by the means 102. Thus, even when the encoder 101 is used, the mis-setting of a timer caused by chattering specific to a mechanical contact is prevented and the time is set accurately.
