Patent JP-H03211072-A (JP)
Title: Type printer
Inventor: TAKAYAMA MAKOTO
IPC: B41J23/02
Filed: 1990-01-17
Abstract: PURPOSE:To ensure that sheets are fed if a load is applied to a sheet feed roller through a sheet by connecting a drive side gear to a driven side gear in a rotating direction with a play. CONSTITUTION:If a sheet is pulled by a user, a load is applied to a sheet feed gear, and this load acts on a driven side gear 3B. However, if a load rests on the driven side gear 3B, the load is not positioned on the driven side gear 3A as the drive side gear 3A which engages with a drive gear 1 by rotation given by a coil spring 11 in an initial sheet feed action has a play in a rotating direction between the drive side gear 3A and the driven side gear 3B. Consequently, the drive side gear 3A engages stably with the drive gear 1 only by action of the coil spring 11, if the drive side gear 3A pulls the sheet, and thus the sheet is fed. Stable sheet feed is ensured as the drive side gear 3A is independently actuated and therefore, they can rotate independently at their specified angles.

Title: Counter circuit
Inventor: SHIGETA YOSHIHIRO
IPC: H03K23/62
Filed: 1989-01-13
Abstract: PURPOSE:To preclude malfunction in up/down switching by providing a delay circuit composed of a logic circuit, and delaying a 2nd clock pulse by a period which is an integer multiple of a 1st clock pulse with an up/down switching signal and then supplying the delayed pulse to a counter. CONSTITUTION:If the up/down switching signal U/D enters count-down mode when a counted number is 10, a clock pulse CLK rises one clock DELTAT after the change point of a reset signal R'. Consequently, even if the switching signal U/D has a slight delay time, the switching signal U/D is inputted to an up/down counter 60 before a next CLK. Therefore, the CLK is inputted in secure count- down mode and the counted number is counted down. Namely, the up/down switching signal is inputted to the up/down counter before the input point of the 2nd clock pulse, so malfunction in mode switching is eliminated.
